BALlNG-PRESS.

SPECIFICATION forming part of Iletters Patent No. 300,642, dated June 17, 188%.

Application filed September 19, 1883. (No model.)

To all whom, it may concern:

Be it known that I, ALBERT S. ROBINSON, a citizen of the United States, and residing in the city and county of Albany, and State of New, York, have invented certain newand useful Improvements in Baling-Presses, of which the following is a specification.

My invention relates to a duplex balingpress having mechanism for operating the IO duplicated parts of the same, devices for exerting pressure on the formed bales, feedingchambers, automatically-feeding mechanisms, automatically-operating gates for opening and closing communication between the feeding- I 5 chambers and their respective platen-chambers, automatically-operating dogs for holding sections of material thrust into the pressing-chamber from moving back, and mechanism for equalizing the movement of the sweeplever and 'for preventing a rebound of the same when the platens commence their return towardthe front ends of their respective platen-chambers.

lhe objects of my improvements are to pro- 2 5 vide means for increasing or diminishing the friction of moving in the platen-chamber, and for automatically feeding the material to be baled into the respective platen-chambers of the press in the form of sections, which will be gradually compacted in their passage from the feeding-chamber to the platen-chamber and be closed therein by the automatic action \of mechanism, so that the operator will be only required to introduce the material alternately 3 5 within the flaring and conveniently spreading open ends of the feed-chambers; and, also, to provide means by which the introduced sections of the material, as they are thrust into the pressing-chamber, will be held in place for moving backward; and, also, to provide mechanism by which a rebound of the sweeplever will be prevented at the times of the end of forward thrust of the platens, so that all liability of accident to the animal will be ob- 5 viated and the power of the driving mechanism of the press will be equalized. I accomplish these objects by means of the mechanism illustrated in the accompanying drawings, in

which there are thirteen figures illustrating my invention, in all of which the same designation of parts by letter-reference is used.

Referring to the drawings, Figure 1 is a view 1 of my improved press from above. Fig. 2 is a side elevation of the same view from the feeding side thereof. Fig. 3 is a longitudinal sec- 5 5 tional elevation taken at line No. 1 in Fig. 1. Fig. 4. is a view of the rear end of the press. Fig. 5 is a rear side elevation of the gear mechanism of the press. Fig. 6 is a horizontal sectional view of the feed-chamber, feed mechanism, and gate on an enlarged scale, and taken at line No. 2, Fig. 2. Fig. 7 is a transverse sectional elevation taken at line No.

In the drawings, A A. represent the frame of the body of the hay-press, which press is duplex in its character in respect to the respective chambers, platens, and mechanism for operating the adjunctive moving parts of the same by a single system of driving-gear mechanism. I These duplex parts may be arranged horizontally and neighboring side by side, thou gh-I prefer to arrange them vertically, neighboring, and one over the other, as shown. These duplicated parts in my improved press are the platen-chambers B and B; feed-openings a and a, connecting each to its respective platen-chamber from the same and one side of the press; pressing-chambers b and 0, commencing at the rear end-throw of the platens and extending rearward to the forward end of the baling-chamber; the baling-chambers G 0, extending rearward from the pressing-chan1bers to the rear end of the body of the press; the feeding-chambers D D, connecting, respectively, with the platen-chambers B B through their respective feed-openings a a,- feeding mechanism E E, moving in direction from the outer end openings, 0 c, of the feed ing-chambers toward reed-openings a a; feedchamber-clearing gates F and F; quadrantpinions G and G; racks H H for operating said gates; platens I and I; pitmen J and J; crank-arms K and K for operating the platens fromthe gear-operating mechanism of the press; friction-lining L L of baling-chambers G O; depressing-bars (Z d and their drawbolts (2 e and brackets f f for adjusting said 5 friction-linings in relation to the permanent opposite side lining of said bailing-chambers.

As adescription of one of each of the abovenamed duplicate parts will suffice for that of the. other parts, I will describe only those parts and elements shown in the upper half or horizontal portions of the press in the drawings.

The framework of the press is made to in clude the operating-gear mechanism, the platenchambers, press -chambers, and balingchambers. This'frame is so made as to inclose between its side portions a horizontal middle partition, .A, formed by cross-bars framed with the middle horizontal plates of the frame and bottom lining, g, of the upper series of chambers, and top linings, g, of the lower series of similar chambers. This partition completely separatesthe two series of chambers. In one of the side linings or walls of platen- 2 5 chamber 13 is made feed-opening a, which has a vertical extension equal to the vertical distance the upper and lower linings of said chambers are apart, and with a horizontal eX- tension a few inches shorter than the length of the movement of platen I in said chamber. Pressing-chamber b is made with closed sides, and top and bottom linings or walls, in which each one of each two of its oppositely'located walls is parallel with the other. V

The lower wall or floor-lining, g, of balingchamber is arranged on the same horizontal plane with the floors of the platen and pressing chambers, and is fixed in position, and the two oppositely-located sides of each of these a1ing-chambers are made open from the hori- .ontal plane of their respective friction-linings L to thehorizontal plane of the bearingsurfaces of linings g and g, respectively, as shown in Figs. 2, 3, 4, and 8. These openings Mextend in a horizontal direction from the rear end of pressing-chambers b b to the rear of the press, and said linings L L and g g of these baling-chambers are free from projecting marginal boundary-ledges or guiding-strips.

Secured to linings L L and g g" at about central in the width of their bearing-surfaces are longitudinal ways in on. These ways are preferably made of metal, and with a V-shaped form in their cross-area, though they may be made half round or oval or rectangular in form of cross direction; and, if preferred,they

may be made of hard wood. These ways in each baling-chamber are in situation opposite each other-one above and one belowas 0 shown in Figs. 4 and 8, and they extend from the rear end of baling-chamber to near the forward end of pressing-chambers b b, as shown in Fig. 3. M is the partition-board, made in the usual manner, and provided with tyingofi slots, as heretofore made. The opposite ends or edges (above and below) are each provided with grooves m, corresponding in form, size, and situation with the form, size, and situation of ways m,- secured to thelinings of the baling-chamber, so that said grooves will engage with said ways and be held therewith and guided in its progressionally-rearward movement toward the discharge ends of the baling-chambers. Each face side of said partition-boards is provided with two or more spurs, which project to a short distance outward from the plane of the face surface of the board. The spurs engage with the end of the bale. The board is set against and held with the bale as itand the board are being progressively moved rearward,so that the bale is stead.- ied and held from twisting. At the same time the ways m m will themselves be made to hold with longitudinal grooves, which will be gradually formed in the sides of the bale by said ways as the material is being forced into the pressing-chamber. By thus making the. two oppositely located sides M of the balingchamber to consist of a single opening extend. ing from lining to lining, the bale may be tied off nearer its longitudinal corners, and any number of ties may be applied to the bale in a convenient manner, the partition-boardbeing provided with tying-ofl'slots to correspond.

The upper wall of lining L of baling-chamher 0 is made of planking-boards, which are continuous with the upper lining or walls of the platens and press-chambers. These planking'boards are held to the upper cross-timbers, A of the frame by bolts or screws, as shown in Figs. 1 and 3. The portion of these planking-boards which extends rearward of pressing-chamber b and from the upper side lining of the baling-chamber is free to be deflected in a vertical direction from a true plane line.

Placed loosely on the upper side of the friction-lining board L of bale-chamber C, and between the upper longitudinal plates of the frame, is the stiflening-rack N ,formed of bars a and tie-pieces n, which are held together by bolts. This rack is made with a length 'suflicient to be extended from the rear end of the lining of pressing-chamber b to the rear end of the baling-chamber. This stiffeningrack, resting on the top friction-lining, L, of the baling-chamber, rises up even with the top surface of the longitudinal top plates of the frame, and extends from side to side between said top plates, as shown. Secured to the rear end of this stiffening-rack is crossbar a". Arranged across the rear end portion of this stifl'eningrack N is depressing-bar d, which is made with notches in its end portions, as at n, from its lower side, so as to readily receive the lower side portions of the bar between the shoulders of these notches between the top plates, as shown in Fig. 4. The outer projecting ends of this depressing-bar are pierced and receive screw-threaded drawbolts 6 e, which bolts are each provided at one end with a head and the other end with a screw-nut, e 6. These draw-bolts also pass through brackets f f, secured to the sides of the frame on a vertical line with the holes made in depressing-bar d,- and when the screwnut is tightened on the draw-bolts they will draw on depressing-bar d, and force the rear end of stiffening-rack N and the top lining, L, downward, so that it will be deflected from a true parallel line with the floor or bottom lining, g, and cause the vertical extension of the rear end of baling-chamber O to be a little less than the vertical extension forward end of the same chamber. A slacking of the nuts will relieve this depressingbar and permit the top lining of the chamber to resume its normal position. The lower series of chambers, B, b, and O, are made substantially in the same manner,with this differencethe bottom lining, L, of lower baling-chamber, O, is made to be a friction-lining,'and capable of being deflected the same as friction-lining L of the upper baling-chamber, and the stiffeningrack N,made similar to and'operating as stiffening-rackN, is placed beneath, as shown.

Secured to a side of the body of the press, and extending outward from. the same from feed-opening a of upper platen-chamber, B, is feeding-chamber D, which feed-chamber has its two oppositely-located sides I) I) made to flare outwardly as they are extended outward from said feed-opening. The contracted end of this feed-chamber terminates at said feed: opening, and is the discharge end, while the enlarged end is open and is the receivingmouth of the chamber. I prefer to make the transversely-located sides t 1)" of this feedchamber also flaring in part or whole, as such flare will increase the capacity of its receiving-mouth. The inner end of wall I) of feeding-chamber D is made to curve back in direction of the backward movement of platen I and toward the margin edge of feed-opening a, as at 0:. (Shown in Figs. 1 and 6.) By the above-described form of feeding-chamber the walls of the same are made to compact the material to be baled while it is being thrust forward from the receivingmouth through this chamber, and be discharged into the platenchamber, and each charge of hay (or other material) will be introduced into said platenehamber in the form of a partially-compressed charge, which will form one of several sections of a bale when the same is completed, and which will be readily detachable from the other similarly-formed sections of the balev when it is broken open. I

Arranged at the sides of the oppositely-located flaring sides I) b of feeding-chamber D are inclosed feed-mechanism chambers O O, which inclose each feed mechanism E E. These chambers O O communicate with the feeding-chamber through openings or slots 1) 9, made in its respective side walls, I) If, as shown in Figs. 2, 6, 7, and 8, and through slots or openings pp project the moving spurs q q of feed mechanism E E, which engage with the charges of hay (or other material to be pressed) to carry the same from the receiving-mouth of the feed-chamber into the platenchamber through feedopening a, in the form of a partly-compressed section of a bale.

The preferred form of feeding mechanism is shown by full lines in Figs. 2, 6, 7, and 8, and dotted lines in Fig. 1, and consists of vertical shafts r r, passing through chambers O O ata short distance from the ends of said chambers, and having a series of sprocket-wheels, r 1" r r, secured to each, so as to revolve with the same. Carried by said sprocket-wheels are endless chains r with the links of which (at distances of about four inches, more or less, apart) are made spurs q q. These spurs are carried by the said chains in direction indicated by arrows l in Figs. 1, 6, and 8, so that the spurs, projecting the feeding-chamber from its flaring walls, will be carried toward feedopenings a, while, when they are returned, they will move in an opposite direction in chambers O O. The endless chainsr are supported from sagging and against being crowded back by recessed ways 8. in which the links move, and the edges of slots 1) p, in which spurs q q move, are preserved from wear by metal strips 8, all as shown in Figs. 2, 6, 7, and 8. The sprocket-wheel shaft 9' in feed mechanism chamber 0, nearest to platen-chamber B, is set as near'to said chamber as possible to havespursqclearthe sides of the platen neigh boring the ends of the spurs as they turn back with the sprocket-wheel off from feed-chamber a. The portion :0 of flaring wall b of the feed-chamber is made with such a curve that the recessed ways 8 s and slots 1) 1) will be made to gradually extend beyond spurs q q, as the latter turn back at curve :20.

Secured to the lower ends of vertical sprocket-wheel shafts 0" r, nearest to the body of the press, are gear-wheels Q Q, made each with an equal diameter as the other, and working each with the other to revolve said shafts in opposite directions, and carry the series of spurs in direction of arrow 1, as indicated in Figs. 2 and 6. Secured to one of the same shafts, r,

so as to revolve with the same, is a sprocketwheel, B, which sprocket-wheel is actuated by sprocket-wheel B and endless chain R and this second sprocket-wheel R is actuated by endless chain B and sprocket-wheel B", secured to the vertical drivingshaft S.

Supported in vertical bearings in longitudinal plates A A of the frame, and at near the rear edge of feed-opening a, is vertical shaft T, to which is rigidly secured gate F.

iSecured to the upper end of gate-shaft T is quadrant-pinion G, which has made with it tripping projection t and catching-notch t.

This quadrant-pinion is so set in relation to gate F that when the former is folded back into flaring side wall I) of feed-chamber D the first cogs of the series in pinion G will be made to project off over the top of the pressbody, as shown in Fig. 1, when tripping pro- I jection tand notch t will be relatively on a vertical line with gate F. Being thus arranged in relation to gate F, pinion G will, through shaft T, turn said gate from position against side I) of the feed-chamber to position parallel with the line of movement of platen I and close feed-opening a, as shown and indicated in Fig. 6.

Pivoted to bracket a, secured to platen I, is rack-bar H, Figs. 1 and 3. To the free end of said rack-bar is secured rack it, having cogs corresponding with cogs of quadrant-pinion G, with which said rack is to engage. Immediately rearward of the series of cogs in u is check if, against which projection it will strike when pinion G p is turned up by the pushing force of rack-bar H, when the latter is thrust forward. Pivoted to the upper side of the press, or to an adjunct thereto, is dog it", having spring a bearing against its back for throwing it forward to engage with notch t in pinion G, when the latter has been turned up to its full distance by the movement of rackbar H. I

Pi'voted to the top of the press is lever u This lever is connected at its lower end to dog if, at a point about at the middle of its length, by connecting-rod a. Secured to rack-bar H, at a point back of the rearward cog of the series in rack a a little less than the length of the forward movement of the platen, is tripbloek a which is made to strike against the upper end of the lever a and thrust it forward, (just before the platen has finished its forward thrust,) and, through connecting-rod a, draw dog u" out from engagement with pinion G, so as to leave the latter free to be turned back. a

Secured to the upper end of quadrant-pinion shaft I is eccentrical quadrant-pulley T, Figs. 1 and 11. This pulley is so arranged in relation to quadrant-pinion G as to be in op position to the same, and is connected (at its point of greatest throw) to compression spiral spring T by pull strap, chain, or cord, t

This spring T is inclosed in holder T, which is secured to the top of the press. The spiral spring is made to have its forward end bear against the forward end of holder T and a draw-rod, t passing through the forward end of the holder, and also through the spring, draws on the rear end of the latter and compresses the same when a drawing strain is exerted on draw strap or cord t by eccentrical quadrant-pulley T. By the employment of this latter device, with the compression spiral spring T the elastic pressure is'made to exert equal force on pulley T, for turning shaft T and swinging gate F from closing position at feed-opening a to an open position at the side of the feeding-chamber, as illustrated in Fig. 1.

Made in the top of the press is a narrow slot, 9 in which bracket u (attached to platen I and connected with rack-bar H) works, as shown in Figs. 1 and 3. I p

In my duplex press I duplicate all the abovedescribed parts, except the sprocket wheel shafts r r of feeding mechanism E E, for said shafts extend from top to bottom of the press.

the same manner as is upper gate, F, but alternatel'y with the same, according as platens I I are respectively moved alternately in opposite directions in their respective chambers, and forward and back past their respective feed-openings a a.

The duplicated platens I I are so geared to the driving-gear mechanism that they are made to move in their respective platen-chambers B B in a reciprocating manner, with platen I moving forward while platen I .is being drawn back. To each of these platens are pivoted pitmen U. The opposite ends of these pitmen are each connected with crank-arms K, carried by vertical shaft U supported in proper bearings by the framework of the press. Secured to double-crank shaft U", between the cranks, is gear-wheel U which gearwheel is actuated by pinion U, attached to vertical shaft S, which shaft is supported in proper bearings from a side of the frame-work of the press. The upper end of shaft S is preferably squared, and has attached to it sweep-leverV by a squared socket made with the connecting end of said lever, and the sweep is steadied by any ring, collar, and braces, or equivalent devices. Mounted on shaft S, at a point below the sweep, and at about on a plane with the top of the pressbody, is bevel-gear t, which actuates bevelpinion o, secured to horizontal shaft 1)", supported in proper bearings from the timbers of the press. Mounted on this horizontal shaft is fly-wheel W, which will be revolved at high speed when bevel-gear 'v on shaft S is revolved by sweep-lever V, and the momentum of said fly-wheel will operate to aid the animal drawing on the sweep lever to carry pitmen U U past the centers of the-crank-arms at the finish of each stroke of the platens when the resistance to the platens is the greatest, and also operate to prevent rebound of the sweep after the pitmen have passed the centers of said crank-arms. The movement of sweep-lever V in direction of arrow in Fig.1 will revolve drive-shaft- S and give motion to sprocketwheel 1% on the said shaft at the same time motion is imparted to double-crank shaft U and fiy-wheel W.

\Vorking in slots made in the top and bottom linings of the press are pivoted a series of dogs, Y. The engaging ends y of these dogs are made with a vertical line of surface in front and with an inclined line of surface running rearwardly, as shown. The dogs working through the upper or top linings of both the platen-chambers are weighted forward of their pivots, while the dogs working through perforations made in the lower or bottom linings of said chambers are weighted rearward of their pivots. Made with the rear end of each of said dogs is an incline, y, Fig. 3.

Secured to the rear ends of each platen, and to the upper and lower sides thereof, are

wedging-blocks z z, in number and position tion corresponding with the number'and position of dogs Y. Made in the top and bottom linings of the respective platen-chambers are slots 2 2, corresponding in number, size, and

place with the number, size, and place of wedging-blocks z 2. These slots z z are made with a length from the rear end of the top and bottom linings of the platen-chamber forward to a distance equal to the length of the movement of the platens in said chambers. Then the platens are moved forward, the wedgingblocks z 2 will move forward in slots z 2 until the platens have made their full movement, and will carry wedging-blocks z 2 against inclines y of the dogs and force their engaging ends 'y inward toward said platens and into recesses Z2 2", provided in the upper and lower sides of said platens from their forward ends.

A belt-wheel, Z, may be secured to the flywheel shaft v for driving the gear mechanism of the press from any convenient power for operating the several moving parts of the press. In such a case Iwould employ a clutch with the fly-wheel and belt-wheel for the ready and convenient removal of the power from or application of the same to the gear mechanism of the press.

The manner in which the several parts of my improved press operate is as follows: The top lining, L, of the upper baling-chamber, B, and bottom lining, L, of the lower chamber, B, will be deflected, as indicated by dotted lines in Fig. 3, so as to give such a sufficient contraction to the discharge ends of said chambers as will produce an amount of frietion which will be required to produce bales of preferred density. This deflection of said linings is produced by turning screw-nuts 6 6 Figs. 1, 2, 3, and 4, on draw-bolts c 6 against bars (I d, when said bars willbe drawn against the rear ends of the stiffeni1ig racks N N,

bearing against linings L and L, and through said racks deflect said lining from true horizontal lines, as shownby full lines in Fig. 3, to slightly-inclined lines, as indicated by dottedlinesin the same figure. The forward ends of said racks will be held from rising by their being held beneath cross-bars A", as shown in Figs. 1 and 3. By these above-described means one of the lining-walls of each balingchamber will be so adapted to be set at will at a gradually-inclined line (in relation to the oppositely-located horizontal lining) which will extend from the rear end of pressing-chambers b b to the discharge ends of said balingchambers without any disturbance of the frame of the press, as heretofore required for producing a frictional resistance to the passage of the bale from the baling-chamber. If preferred, in some cases, the stiffening-racks N N may be omitted and bars d d may be made to have bearing directly on linings L L. In such a case the deflecting lines of linings L L will naturally partake a slightly-curved form. Platens I 1 are operated in a reciprocating manner in their respective chambers with the movements of the upper platen alternating in opposite directions with those of the lower platen. \Vhen the material to be formed into bales is introduced into the platen-chambers through their respective feed-openings a a the respective platens will by their alternate forward movements thrust forward, alternately, the charges of material from their respective chambers B B into their contiguous pressingchambers b I), where they will be shaped in a compacted section, to be subsequently alternately thrust rearward into the respective baling-chambers G C. When the charges of material in the platen-chambers are being thrust rearward in direction of arrow 3 in Fig. 3, the material thus moved will be made to slide against the inclines made with the engaging ends g of dogs Y, and force said engaging ends outward from said material and elevate the opposite ends of said dogs, and when the platens have made their full-extent thrust toward their respective pressing chambers the material will be carried fully into the latter and slightly past the engaging ends of said dogs, and at the same time the wedging-blocks z z (secured to the rear end portion of the respective platens) will ride on the inclined surface y of dogs Y, and force the engaging ends of the same inward, so that they will bear against the rear side edge of the section of the compacted material thus thrust into the pressing-chamber, and be held from passing or moving back into the platen chamber. These dogs are positively operated in one direction by the moving compacted section of material being pressed, and in the opposite direction by the platen, and the use of springs is dispensed with for holding them in effective engagement with the compacted material.

Platens I l are operated alternately forward and backward in their respective platenchambers 13 B by the pitmen U, as they are actuated by crank-arms K, revolved by shaft equalize the movements of these several parts. When the gear mechanism is to be.operated by the sweep-lever V, pinion U on shaft S and gear U on the double-crank shaft will be dispensed with, and a large driving-gear, as, (shown in dotted lines in Figs. 1 and 4,) will be secured to shaft S in place of pinion U, and a small gear-wheel, :19, (about one-half the diameter of gear w,) will be secured to double-crankshaft U in place of gear U, so that the double-crank shaft will be made to revolve twice to each revolution of drive-shaft S. \Vhen sweep-lever V is made to revolve shaft S, bevel-gear c on said shaft will actuate bevel-pinion o, and through it revolve flywheel WV to a high speed, and thereby equa1- ize the speed of driving-shaft S, when, crankarms K K are passing the centers, and also prevent a sudden acceleration of the movement of the sweep-lever toward thevanimal drawing on the same at the time of finish of the forward thrusts of the platens and its start backward, and thereby remove all possibility of endangering the animal by a rebound of the sweep, as heretofore had in baling-presses driven by sweep-lever. \Vhile the pressinggear mechanism and platens are being operated, as above described, sprocket-gear R, attached to driving-shaft S, will, through endless chain R'', revolve sprocket-wh eel R, which sprocket-wheel will, through endless chain R and sprocket -wheel It, revolve one of the shafts r and gear Q in direction of arrow 4 in Figs. 1 and 2. 1 Gear Q will revolve gear Q and its attached shaft r in direction of arrow 4 in same figures. These shafts r will revolve their respective sprocket-wheels r r, carrying chains 0*, moving in recessed ways 8 s, with their attached spurs q q moving in slots 1) p in direction of arrows 1 in Figs. 1 and 6. \Vhen the operator introduces aforkfull of hay (or other material to be pressed) into feeding-chamber D, (or D,) the rapidlymoving series of spurs q q of feeding mechanism E (or E) will engage with said material and carry it inward toward feed-openin g a, (or a.) While the material is'being carried inward, the inclined or gradually-contracting sides of feed-chamber 1) (or D) will operate to gradually compress the material as it is being advanced into the platen-chamber B, (or B.) As the material is being compressed by the inclined sides of said chamber, feedingspurs q (1 will be made to have their strength of engagement with the material gradually increased, because of the increased compactness of the latter when approaching the feed-opening a (or a) before entering the platen-cham- It will be .observed that the feed mechanism working in the inclined side I) of the feedchamber next to the head end of the platenchamber is made to run nigher to the platenchamber, and that this incline curves back at w, .so that spurs q will have engagement with the compacted charge of material being introduced until it has been nearly wholly introduced into the platen-chamber, and that this curved portion 00 of wall b receives the entire length of spurs q in recessed slots 8, and operates to withdraw said spurs from the material just about at the point the \curved portion a: of said wall contributes to enlarge the throat of the feed-chamber at the feed-opening to the platen-chamber. By this form of construction and arrangement of said parts the side portions of the compacted material next to the face of the platen (before it is carried forward) are made to fully enter the platen-chamber before the former has been moved forward past curved portion 00 of wall I)". Vhen the compacted charge has been introduced into the platen-chamber, the platen, moving forward, will force the charge toward and into pressing-chamber b, (or b,) when dogs Y will be operated by wedging-blocks z z and ,made to hold against the rear side of said compressed section of material.

When the charge of hay compacted in the feeding-chamberD (orD) has been about fully introduced within the platen-chamber by feed mechanism E (or E) platen I (or I) will have commenced its forward movement toward pressing-chamber b, (or b,) and, continuing its forward movement, it will carry pivoted rackbar H (or H) forward with its rack a, engage with quadrant-pinion G, (or G-",) and operating the same to. swing gate F (or F) inward from its folded position at inclined side I) of feeding-chamber, as shown in Fig. 6, to a closed position at feed-opening a (or a) at the side of the platen, as indicated by dotted lines in same figure. The gate, in swinging forward to close feed-opening a, (or (5,) will carry before it into the platen-chamber whatever of the rear end portion of the compressed charge of material there may be in the feed-chamber at the time the gate is closed. This closed gate will operate temporarily the same as the opposite side wall of the platen-chamberfor guiding the compacted charge of material in its passage to pressing chamber b, (or b.) As soon as quadrant-pinion G (or G) has been operated by rack-bar H (or H) to fully close gate F, (or F,) tripping projection 16 will arrive at check a on said rack-bar and lift the same. At the same time dog a is made to engage with notch t in said pinion, and hold the same locked from turning back. Thus dog a and quadrant-pinion G (or G) are made IIO to lock the gate in a closed position against the side of the platen-chamber until the platen has been moved to within three or four inches of the completion of its forward thrust. When the platen has nearly completed its forward movement toward pressing-chamber b, (or b,) tripping-block a carried on the rear portion of rack-bar H, (or'H,) will strike the upper end of lever 21? and force the same forward toward quadrant-pinion G, (or G,) when dog a will be drawn back out of engagement with notch t in said pinion, and the pinion and its connected gate will be free to be turned back to their normal positions by the united action of quadrant-pulley T and spiral spring fl and their connecting strap or chain and be held by the same with gate F (or F) folded in its place in the face side of inclined wall I) of the feed-chamber. lVhen gate F (or F) is folded back to its normal position in its side of the feed-chamber, a second charge of material will be introduced in the feed-chamber, when the several devices will operate again to effect a like compression of the charge, and also the introduction of the same in a compacted form into the platen-chamber, and also a shutting in of the charge by the gate, and a thrusting forward of the saine against the preceding charge, and moving both forward in the pressing-chamber and toward balingchamber 0, (or C.)

As before stated, the upper and lower feeding mechanism, E E, of the respective feedingehambers are moved simultaneously, while gates F F are operated alternately with the movements of each of thelatter, timed with the movements of the respective platens, which primarily operate to close and release their holding devices, as above described. It will therefore be readily understood that the charges of material to be formed into bales are to be introduced alternately in feedingchambers D D at the times their respective gates F F are turned open, like as shown in feed-chamber D in Fig. 2, and such introduction of charges will be stopped while the gates are closed, like as shown in lower feed-chamber, D, in same figure.

By these above-described improvements I am enabled to form two bales simultaneously by alternately-fed charges introduced mechanically into the platen-chambers in a compacted form of sections.

In Fig. 9 the gate F (or F) is shown to be made with a hollow sleeve, c", having arms 0 c separated by slots 0', with slots 0 c terminating with recesses 0 made with the sleeve portion of the gate. Then this gate is turned back into its place in side b of feeding-chamber D, (or D,) spurs q q of the feeding mechanism will be readily received into slots 0 0* between arms 0 0, while the spurs, when turning at the sleeve of the gate, will move recesses c 0 whether the gate be stationary or swinging toward or from side N.

If preferred, tripping projections i, made on pinion G, secured to gateshaft T, and catching-notch i, made in said pinion, may be made with a separate and independent piece from pinion G and be secured to the same shaft; and also, if preferred, a weight, cord, and pulley may be substituted for spring '1 for operating with the quadrantpulley T for swinging gate F from a closed position to an open one; and, further, band-pulleys and bands or band-wheels may be employed in lieu of sprocket-wheels and endless chains for communicating motion to the feed mechanism from the revolving mechanism operating the pitmen of the platens.

By my above described improvements a greater quantity of material will be formed into bales in a given time than has heretofore been accomplished, because of the automatic feeding of the material to the platen-chambers in a partly pressed or compacted form from material alternately introduced into the flaring ends of the feed-chambers in a convenient manner without any expenditure of time or manual labor for its introduction through the feeding-chambers to the platen-chambers.

I am aware that shallow and flaring-sided hoppers have been employed with the feedopening to platen-chambers of a baling-press for the purpose of conducting, in a more cleanly manner, the material to be baled into the platen-chamber. Such hoppers form no part of my invention, as they are not in the least adapted to compact the material in its passage to the platen-chamber, as does my feedingchamber; and, further, these shallow hoppers are not in the least adapted to receive a feed ing mechanism in their sides for coaction with the sides for forming and introducing compacted sections of material into the platenchamber, as is my above-described feedingchamber. \Vhen bales have been formed of compacted material'by successive charges received from the feeding-chambers, the bales will be tied off or banded and ejected in the usual manner practiced by the trade, which is so well known as to require no particular description.
