Specification of Letters Patent.

Patented. ay a l, 1915,

Application filed April 16 1914:. Serial No. 832,156.

b all whom it may concern:

Be it known that 1', Enmcs'r L. GALE, Jr, a citizen of the United States, residing at Yonkers, in the county of Westchester and State of New York, have invented anew and useful improvement in Conveyors, of which the following is a specification.

My invention relates to improvements in endless conveyors and has a general appli- 0r freight carrying type, traveling in a hbrizontahinclined or vertical plane.

One Jf'the objects of the invention is to provide--an endless conveyor, having later ally movable carriers or treads, whereby objects conveyed thereby are landed or discharged therefrom to the side of the conveyer.

Another object of the invention is to provides conveyor operable automatically to discharge vlaterally at one or more points or side landingsdn its path of travel.

Still another object of the invention is to provide a ilective control systein whereby each carrier or tread can be independently controlled automatically to discharge only at the desired one of ,number ofdandings.

Another object of the 'nvention is to provide an endless convey r operable to discharge objects conveyed thereby at one or more points at one orboth sides'of the conveyer, and in a longitudinal direction, making the conveyor in etlect, a three way discharge conveyor.

Still another object of the'invention is he provision of a hand rail capable of lateral movement with the carriers or treads.

A still iurther object of the invention is capable of discharg} to the side thereof, without requiring a step to be taken by the passenger from the escalator to the landing. which is effected byJhe present invention by iroviding transversely movable treads which will slide the passenger therefrom to the landing. Other objects of the invention will appear more fully hereinafter, the novel cornbinations of elements and arrangements ol parts being pointed out in the appended claims.

Referring now to the drawings, shows a eonveyer of the step type, being more or less diagrammatic; Fig.

shows an enlarged detail view of rollers, etc, shmvnin Fig. i; Fig. 8 is a part sectional plan view of certain portions of Fig. 7; Fig. 9 is anenlarged plan view of the deflecting track system as arranged at the landings l), E and 1*, shown in Fig. 2, together with various other electrical apparatus; Fig. 10 is a modified construction for effecting the lateral movement of the carrier; Fig. 11 shows a hand rail such as is associated with each tread; is shows a. carrier or modified construction, more particularly adapted to carry loose material; Fig. 13 shows a carrier or tread of modified construction, the same being adapted to move laterally over the side of the conveyer.

Referring now to Fig. l, truck frames .1 are providedwith wheels 2, which oo-act with tracks or ways 3 and l. These tracks are of a well known construction and are therefore illustrated diagrammatically. T he trucks are connected together in a well known manner, as for example by suitable driving chains or llnlis .8, to form! an and less carrier. The chains are driven in a well known manner, as for example by means of sprocket wheels (3, which are driven by a set of gears 7 driven by any suitable source of power.

Each truck is provided with two laterally movable carriers or treads 8 and 9 4) which I have shown in the form oi? endless bolts. The carrier and particularly the working surface thereof, may be made of leather, rubber, sheet steel, or in fact any of the well known carrier or treads having" flexibility, may be employed; These bolts are carried by rollers 10 and ll, respectivel and additional sets ol' rollers 12 and 13 are LII run of the conveyer onto a landing G. It i trucks 1 being such movement of the the passenger. These rails are located at the provided to prevent sagging of the belts. The rollers and 11 are carried by shafts l4 and 15 respectively, said shafts being suitably journaled in bearings 16 and 17 The carriers 8 on the left side of'the trucks are'adapted to land or discharge objects conveyed thereby to the left side of the con veyer, each carrier being independently con trolled as hereinafter described automatically to discharge-at any one of the plurality of landings A, B or C. The carriers 9 are controlled in a like manner to discharge to the right side of the conveyer, to any one of the landings D, E or F. These 1andings as illustrated in Figs. 2 and 4, are in the formof belt conveyers which are operatingat right angles to the main conveyer,

such an arrangement being obviously forfrelght se1v1ee,.etc.

adapted for passenger service, stat1onary When my conveyer is landings are provided, such as illustrated in Fig. 3, the said landings being cut away as shown atl'S, so that the top surface 18 thereof is flush and in close proximity with i the tread surfaces of the conveyer.

A third tread or carrier 19 is fixed stationary on the truck frame, this carrier being adapted to discharge atthe end of the will be here noted that each one of the provided with three carriers, 8, 9 and l9, makes the conveyer in effect a three-way discharge conveyer. A hand rail 64 is provided for each carrier,and co1n-' prises an upright or standard 65 which 1s suitably secured to the carrier. This standard maybe n the form of a wooden ornamental panel having the hand rail portion 64 formed at the top, for the hands .of

the passenger. These panels may be of the same length as the carrier shown in Fig. 1, the same of course being movable laterally with the carrier and the passenger can there for maintain a hold on the same during carrier "to discharge right hand side of the carrier 8 and at the left hand side of the carrier 9 as shown in Fig. 11. I

In ordernowto' effect thedi'scharge operation or lateralmovement of the carriers 8 and 9. I associate with each carrier ablock 20 (see'Fig. 7) carrying a rod 21, which supports a. roller 22. These rollers travel between suitable tracks 23, which are positioned nearthe outer edge of the conveyer, and extend in alinement therewith as shown at 23. At the first landing point, such as D for example, the tracks deflect inwardly as shown at 24, and extend again in alinement with the conveyer as shown at 25. The rollers 22.will thus be deflected by the deflectortrack 24, and there y cause a lateral'movement of the carrier or tread,

which movement thereof is eg lialfto the flectors which rack is positioned at each carrier,

- are, provided with width of the tread surface as designated by the arrows b-b, which amount of move ment thereof will efiect the complete dis charge of objects from said carrier. Guides are attached to each truck frame, and-engage slots 56 in the blocks 20, these guides serving to steady the said blocks and pre vent buckling of the belt, as the rollers F are deflected. The rollers 22 after passing through the deflector track 24, follow the inward tracks 25 whichextend in alinemen't with the conveyerto the end of the run thereof, whereupon they extend to-the return run of the conveyer, and again deflect as shown at 26 to the outer edge designated 27of the conveyer, and from there extend continuously through the return run of the ied throughout their entire travel on the upper or working run of the conveyer. Tracks 28 and 29 extend from the landing D to landing E and F respectively, and deand 31 are positioned at the said landings, respectively, each deflector leading to the inner tracks 25. These deflectors 24, etc., may .be independent sections, so that they may be placed at any point along the run of the conveyier where it is desired to discharge. eral movement of the treads or carriers may be varied by changing the angle at v which the deflectors are set.

In the modified construction shown in Fig. 10 for effecting a lateral movement of v The rate of discharge or latthe carriers, a toothed rack 32 is provided,

I each landing. The rack is adapted to be engaged by a pinion 33 which rotates the shaft'lS, through a sprocket and chain connection 3%, which is driven by a bevel gear connection 35, from the pinion 33. The racks 32 of course are made of a sufficient length to effect a of the carrier.

complete discharge movement The selective control system whereby each carrier can be controlled automatically to discharge only at the desired one of the landings D, E or F, comprises manually operable switches 36 and 37, associated with each switch comprising a contact shoe 38 and 39, which are carried byrods 40, 41, respectively, which extend wardly through the truck frame-1.: These out ofcontacting position from contadtjstrip 42, .42

shoes are normallyfheld 43, by springs-4A- -aamtfa e ease 4 l2 and 452, and the shoe 39 is of: a' width in Fig. 9.

= as to be engaged by movement of the rollers 2-2350 as to clear the and 51 receive current sullicient to span both pairs of strips as seen The strips and i2 are posi tioned. at the first deflector Qd, in a position to be engaged by the shoe and 39 and the strips d3, d3 are positioned atthe' second deflector 30, and offset from the strip li, the shoes 39 only. (Janis il? and are normally held in an inoperative position by springs l9, and actuated to operative position by electromagnets '50 and 231, respectively. These cams when in their operative position are adapted to coact with rollers 52, carried by a member 53, which moves ertical ly in a slot at in the rod 21, thereby raising; the;

roller 22 to clear the top of the deflector track at the point 2%, so as not to be deflected by the same. The electromagnets 50 from a suitable source of supply designated ant I The operation will now be described, and since the method of control tor the carriers 8 which discharge'to the left, and the carriers 9 eldchdischarge to the right, is similar, a description. of one set of'carriers will therefore sullice for both sets. for example the carrier 9 on the right hand side of the trucks, if it is desired that all these carriers shall discharge at the f rst landing D, the switches 36 and 37 are left in their normal position as shown, whereby the shoes will not contact with the strips 42, 4 2", and the camel? therefore will remain in its inoperative position as shown, and the rollers will thus bedeilected by the first deflector 24:, thereby ellecting the discharge operation or lateral movement of each car rier at ,the landing D. It now it is desired that alternate carriers be discharged at the landing E, and the others at landing "D, the switches associated with the latter trucks will t n he eft in their normal position as slmwn, and the carriers carried by such trucks will therefore discharge' at the land ing D as above described.- The switch of alternate trucks are actuated, thereby shoving the shoes 3E3 into'position so as-to contact with the contactstrips i2, each of these shoes 38 contact with the strips 42, e2, a circuit is coinpleted'tor the electromag'ent 50, as follows: From. the con ductor to contact strip 42, through the shoe 38 to contact strip &2, conductor 5?,throngh Winding of electromagnet 50, and conductor 58 to line. The electroinagnet thus be ing energized will actuate the cam i? to its operative position, whereby the roller 52 will strike the same, causing the upward Taking top of the deflector 2e at the point 24''. The contact strips are of such a length and are so positioned at the deflector 2%, as to cause the electromagnet 50 to maintain the cam 47 in operative position just long enough to permit the same to effect the upward movement of the rollers 22 at the point 2A, whereupon the shoes 38 ride oi? the said contact strips, causing the deenerglzation of the electromagnet 50, and the rollers 22 will drop between the tracis 28. Since now the shoes 38 can not contact with the contact strips at the landing E, the cam 48 will of course remain inoperative, and the rollers 22 of the said alternate trucks will therefore be deflected by the deflector 30, this causing the discharge operation of said alternate treads at the said landing E.

It it is desired to discharge to thethree landingsl), E and F, the carriers discharglag in consecutive order, that is for example,

as illustrated in Figs. 2 and 9, wherein all carriers designated 9 discharge at landing D, the carriers 9 at landing E, and the carriers 9 at landing F, the method of control is as r'ollows: To elle'ct the dis charge operation of all carriers 9 at ing D, the switches 36 and 87 associated with carriers 9 will-be left in normal position as shown, and the rollers 22 associated with all carriers desi nated 9 will be de ti ctecl by the deflector :24: and thereby effect the discharge operation of said carriers 9 at the landing D To effect the discharge operation of the carrier 9 at landing D",

and .30 and consequently these rollers drop between tracks 30 and are deflected by the deflector 31. Thus the discharge operation of the carriers 9" will be etl'ected at the landing F.

it will be seen that each one of the tr ads or carriers 8 and 9 can be 1" depends itly controlled, automatically to discharge at only a desired landing of a plurality of landings; and furtheinore it will. be seen that I have provided a conveyer operable to discharge to a plurality of side landings simultaneously.

lit will be further noted that the laterally movable treads will move the passengers laterally in the plane of movement of the conveyor, and discharge said passengers therefrom onto the landing. The danger of parel'is entirely eliminated, since the land-- ing or floor plates as shown in Fig. 3 is flush with the -'tread surface and in close proximity thereto.

The landings D, E, F, may all be in substantially the same plane, as would be in the case of ahorizontally movable endless conveyer, or they may be at different elevations, as in the case of an inclined conveyer, illustrated in Fig. 1. I

It is obvious that the conveyer may be constructed with asingle laterally movable tread for each truck, or with two of said treads, such -.as Sand 9, the middle tread 19, being eliminated in eithercase.

Another important feature of the present system particularly in its use for passenger sergice, resides in the provision of a travel ing way by means of which passengers may be transported past all the landings (that is to say the path for the transportation of the passengers s continuous or of unbroken continuity), and yet provision being made to effectapositive discharge of a passenger at any of the landings. This feature will "be readily appreciated since it will be seen that with the present system there are no'obstructions whatsoever at the landings such as shunts, as now commonly used to e'lfeet a side discharge, which shunts form a break in the path of travel of the passenger, requiring a passenger desiring to go past the landing to step off and again onto the travcling way. In the way of giving a concrete example in the way of illustrating this important feature of the invention, we will take a single moving way connecting four floors, now it will be seen that a passenger desiring to go from the first to the fourth floor will have a passage which is continuous or of unbroken continuity between these floors,-the passenger not having to step ofi of and second and third floorsfaud.fln'thermore, it is seen that a positive discharge of a passenger at any of the intermediate floors,

such as theQnd or 3rd floors, can be effected may be used to a or the like, where it is desired to discharge.

if so desired.

A conveyor having trucks each provided with three carriers, as disclosed in Fig. 4, great advantage on a dock at one or more points on one or both sides thereof, and also at the end of the dock also. Thus with the arrangement shown in Fig. 4, this can be accomplished, since each of the carriers 8 and. 9 can be independently controlled to discharge at any desired landings on the left and right side respectively of the conveyor, and the middle carriers 19 discharging at the end of the "conveyor. By means of switches '36 and 37 a despatcher standing at the receiving end of the conveyer,'ca11 control each carrier to freight, etc,

and thereby control the particular again onto the traveling way at the discharge at any of the desired landings. Of course it Will be seen that by removal of the'deflector tracks 24, 30 and 81, all three carriers 8, 9 and 19 will discharge at the end of the conveyer.

The switches 36 and 37 can be so constructed.

' and so arranged that a passenger can con- 'veniently actuate the same by foot or hand carrier on which he is standing to discharge at iany desired landing. A suitable number of these switches, etc, areprovided according to the number of landings, to be discharged at. 'An application of the present invention to a conveyer adapted to carry loose material, such as coal, etc, is illustrated diagrammatically in Fig. 12,in which case the trucks 1 are provided with a plurality othuclc ets 60, which are hinged at 64, to a suitable supporting member 62, carried on rollers 11. The buckets being thus hinged will per-. mi t the same to travel around rollers 11 and thereby effect the discharge of the contents of the buckets.

In the modification shown in Fig. 13, a member 60 provided with rollers 61 su ports the tread or carrier 62, the ends of which are fixed at 63. The member 60' is adapted to be moved laterally over the side of the conveyer, moving the tread therewith in a manner to effect the discharge there from of an object carried thereby. It is -olwiousthat variousmodificatiens to the mechanism herein disclosed Will suggest themselves to those skilled in the art,'1eo one particular instance being in the case of the mechanism foicontrolling the operation of each carrier'to discharge at onlythe'desired landing. It will readily be seen in this instance that instead of lifting the rollers 1'05 22 at the points such as 24, 30, etc., the same can be controlled by track switches located at the said points, with the provision of suitable means such as an electromagnet for controlling the operation of the same, 110 and said track switches can be arranged; so that they will normally prevent the rollers from entering the deflector tracks and wheni actuated pause the rollers to enter the particular. deflector" track associated with the 115 operated track switch.

I desire therefore not to be limited to the precise construction and arrang-ment of parts-as herein disclosed. 1
