llereto'fore in the manufacture of glue it has been customary to set'the glue in molds,

sheets and lay the sheets out on the nets byl Serial No. 489,081. memorial.) Y

' turnedto the glue making department, to be again unstacked, filled, and stacked by hand and returned to the drying-room.

The objectof my invention is to provide a glue-making machine in which the process of making glue may be carried on continuously, and in which the nets may be unstacked, loaded with sheet-glue, and stacked .by machinery ready for transportation to the dryin g-room, thus doing away with manual labor.

My invention consists in the combination of a device for forming glue into sheets, for spacing and subdividing the sheets, and for cutting the sheetsinto sizes for delivery to the drying-nets, mechanism for removing the nets from the stack and carrying them forwardsuccessively to receive the subdivided sheets of glue, and mechanism for placing the filled nets in stacks and removing the stacks from the machine, all as will be hereinafter more fully described. V

In the diagram Fig. 1 I have shown the apparatus 1 for cooling the glue and forming it into sheets arranged in operative relation to the separator-and subdivider 2. I have also shown the relation of the net-unstacker 3, uet conveyer 4, net-stacker 5, and the stackremover 6 to each other. The glue-cooling aud sheet-forming apparatus 1 is shown and described in my application for Letters Patent of the United States, Serial No. 481,621, entitled Apparatus for cooling glue and forming it into sheets, tiled July 27, 1893. As this apparatus forms no part of my present invention, except in so far as it enters into combination with other mechanism, a comessary.

The liquid glue is supplied through a suitplete description of'the same will not be necable valve 7 to a cooler consisting of a series ing over a roller 10 in .the glue-cooler and forming cakes, then to out the cakes iuto sheet-former 1 and over a roller-11 in the separator and subdivider 2.

In the side pieces 12 of the frame 13 of the separator and snbdivider 2 are journale'd drums 14 15 16 17, formed of wheels which receive the endless cords 18 19. The drums 14 16 are journaled in the frame 13 in aplanetwo series of endless cords cross each other at 20 at or near the center of the machine. The cords 18 pass over and lie in the grooves of a grooved drum 21, and the cords 19 pass over and lie in the grooves of a grooved drum 22. The journal-boxes of the drums 14 17 are placed in slots in the end of the frame 13 and are adjusted by screws and nuts, so that the tension of the endless cords may be ad-' justed. The roller 11 is journaled in the frame 13 with reference to the drum 14 and cords 18, so that the endless conveyer 9 may deliver the sheets of glue formed in the apparatus 1 to the series of endless cords 18.

In an upward extension 23 of the frame 13 is journaled a shaft 24, carrying arms provided with cutters 25, which are capable of making contact with the periphery of the drum 21 as they are revolved, thereby cut-' ting-the continuous sheet of glue delivered 'by the endless convcyer 9 to the cords 18 in length-s suitable for filling the nets. On the end of the shaft 24 is mounted a spur-wheel 26, which is engaged by a pinion 27, mounted on a shaft 28, journaled in the extension 23. The said shaft is providedwith asprocketwheel 29, receiving an endless chain 30, which passes around a sprocket-wheel 31 on the shaft of the drum 14. The shaft 32 of the drum 16 is provided with a pulley 33, .which 7 said shaft is furnished with a sprocket-wheel 41, which receives motion through a chain 42 from a sprocket-wheel 43 on the shaft 37. The shaft 44 of the drum 15 is provided with a spur-wheel 45, which takes motion from the spur-wheel 36 on the shaft 37, and upon the ends of the said shaft 44 are spur-wheels 46 47, which engage pinions 46 on the ends "of a shaft 46, journaled in the frame 13, said shaft also carrying next said pinions gearwheels 46, engaging pinions 48-on short shafts 49, projecting inwardly from opposite sides of the frame 13 and carrying on theirinner ends sprocket-wheels 49", engaging endless chains 50. The said chains 50 move in. inclined planes opposite grooves formed in this On the shaft 32 is sides of the frame 13, parallel with the path of the cords 19. The lower ends of the chains 50 are received on sprocket-wheels 51, secured to shafts 52, which project outwardly through the sides of the frame 13. Each shaft 52 is pro vided on its outer end with a spur gear-wheel 53. On the opposite side of the line of intersection of the cords 18 1.) is arranged a similar pair of chains 54, running in inclinedplanesopposite grooves in the sides of the frame 13, the said grooves being parallel with the cords 18.

The shafts 55, carrying the sprocket-wheels- 56, which support anddrive the chains 54, are furnished outside of the frame 12 with spurwheels 57, and the spur-wheels 53 and 57 are connected mechanically by intermediate spurwheels 58, journaled on studs 59, projecting from the sides of the frame. The upper ends of the chains 54ers supported by sprocketwheels 54, which turn on studs projecting inwardly from the sides of the frame 13. 13y means of this construction the chains 50 and 54 are made to revolve simultaneously in the same direction: 1

Upon'each side of the machine a bar 60 is pivotally connected with a link of each of the chains 50 and 54, and the said bars 60 are connected bycross-bars 61. The said cross-bars, in connection with upwardly-projecting longitudinal plates 62, form a transfer-table for lifting and carrying a sheet of glue from the cords 18 and lowering it onto the cords 1!) as soon as the sheetof glue comes into position on the cords 18. The cords 19 are made to travel faster than the cords 18 by proportioning the gears which drive the drum 16, carrying the cords 19 to cause it to revolve faster than the drum 14, which drives the cords 18. The difference between thespeed of the cords 1S and 19 is such as to leave a space of some six or eight inches between the sheets when delivered on the cords 19 by the transfer-table or ICC sufficient space to correspond to the space ex- The mechanism by which the sheets are spaced I shall call a spacer, to obviate the necessity of further describing it.

It will thus be seen that the table 62 iscarried forward to the receiving end of the machine by the chains50 and 54, and that owing to the inclination of the chains the table 62 is inclined, so that when those links of the said chains pass around the sprocket'wheels 49", 51, 54, and 56, by which the bars 60 are supported, these chains carry the bars 60, by which the table 62 is supported, upwardly with a parallel motion, the cars 60 being guided bythe extension of their ends beyond their pivotal connection with the chains which project into the slots in the side of the frame,so that the bars of the table, being parallel with the cords 18, engage the entire sheet of glue carried by the cords, lifting the glue from the cords. The transfer-table 62 is raised by the chains as they revolve, and at the same time is moved forward. At the instant the said transfer-table comes into contact with the glue sheet carried by the cords the velocity of its forward motion is the same as that of-the cords 18 and the glue sheet carried thereby. A further movement of the chains carries the table with the sheet of glue thereon toward the delivery end of the machine, at the same time tilting the table, so as to bring the sheet of glue parallel with the cords 19, when the bars 60, together with the table, are dropped below the level of the cords by the carrying of the pivotal connections of the bars 60 with the chains around the sprocket-wheels 49? and 56 at the delivery ends of the chains.

As the transfer-table descends, its forward motion is retarded, the motion being the resultant of the forward and downward movements, so that when the glue sheet is delivered by the transfer-table to the cords 19 the transfer-table is moving at the same speed as the cords 19, which speed, although slower than the speed of forward movement of the transfer-table when passing from the cords 18 to the cords 19, is faster than that of the cords 18. ,The sheet is carried forward by the cords 19 under the cutters 39, which cut the sheet into strips. Beyond the cutters 39 is arranged a shaft 63,which is provided with a sprocketwheel 64, taking power through the chain from a sprocket-wheel 66 on the shaft 37. The shaft 63 carries two disks 67 68, in which are fastened knives 69, parallel with the shaft 63. The knives 69 are arranged with reference to the strips of glue carried by the cords 19, so that the said knives will cut the strips into short lengths or squares by contact of the knives with the roller 70, journaled in the frame 13. The glue in its passage to the knives69 and roller 70 is transferred from the cords 19 toithe cords 71, passing over the said roller 70, also around a roller 72, journaletl in pillar-blocks 7 3a short distance from the delivery end of the machine. Endless chains 7 4 run over sprocket-wheels 76, carried by shafts 78 79. The said chains 74 are arranged parallel with each other and at a suitable distance apart to receivethe net: lowering mechanism or net-frames 80 and form an endless carrier for conveying the said frames under the separator and subdivider and under the roller 72.-

On opposite sides of the endless carrier at the receiving end of the machine are arranged standards 81 82, two upon each side of the carrier. The'distance between the standards 81 82 of one side and the standards ofthe opposite side is sutficient to receive between them the net-frames 80. The net-frames are provided with two notches in each side for receiving the retaining-pawls 83, which are capable of projecting beyond the inner faces of the standards 81 82 and also of dropping back into a recess in the standard when ,re leased, each pawl being provided withta when released in the manner weighted arm 81 for causing it to drop back presently to be described.

In a plate covering the back of the recess containing the pawl 83 is inserted a rod 84, which is pressed forward into contact with the pawl 83 by the spiral spring 85, surrounding it and abutting against the plate. The outer end ofthe rod 84. passes through an arm 86, secured to a rock-shaft 87, journaled in ears projecting from the standard 82. Upon the rod 84, outside of the'arm 86, is placed a wing-nut 88, and upon the shaft 87 is secnred an arm 89, extending toward the center of the machine into the path of atripper 90, secured to the net-lowering bar 91. The pawls 83 and accompanying devices are the same upon opposite sides of the machine, but oppositely arranged with respect to each other, so that the pawls on one side engage the-notches in one side of the net-frame and the pawls on the other side engagethe notches in the other side of tlleframer The bars 91 are connected at opposite ends with togglejoints 92, the said toggle-joints being oppositely arranged with respect to each other, and a pair of oppositely-arranged togglejoints 93 94 are connected with the middle of each bar 91 and also with the floor, and the intermediate pivots of the t0ggle-joints are connected by rods 95 with the central pivot of the toggle-joints at the ends of the bars 91. This arrangement of toggle-joints and bars forms a parallel motion, whereby the bars 91 are kept in a horizontal position when raised or lowered in'the manner hereinafter described.

Each bar 91 carries a roller-96, which rides upon a cam 97, secured to the shaft 98, there being one such cam on each end of the said shaft, and to the shaft .98 is impartedan intermittent rotary motion by a segmental pinion 99 on the said shaft and a segmental gearwheel'lOO on the shaft 101, which receives-its motion from the shaft 78 th'roughmitengearing 102, the shaft 103, and miter-gearing 104. The stack of net-frames 80 is delivered to the unstacking device from the platform 80. Posts 81*, erected on the said platform, act as stops when placing the net-frames in position to be fed to the unstacker.

At the opposite end of. the machine, beyond the roller 72 and upon opposite sides of the endless net-elevator and frame-carrier, are

arranged posts 105 106, and in the said posts are pivoted spring-pressed pawls 107, which are capable of engaging the notches in the net-frame, and below the level of the endless chains 74 is arranged mechanism like that already described, comprising bars 91*, tog- 97, segmental pinion 99, segmental spu rwheel 100, journaled on the shaft 101*, which takes powerthrough miter-gearing lOt, shaft- 103, and miter gearing 102 from theshaft79.

- Above the chain 74, at the delivery en'd'of to-which reference has been made.

the machine, is arranged a frame 107", in

which are journaled rollers 108 for receiving segmental spur-wheel 124 on' the'shaft 125,-

the said segmental spur-wheel'having a portion of its periphery plain to receive the stop 126', formed on the segmental pinion; The shaft 125 is provided with aspur-wheel 127, which is connected through an intermediate spur-wheel 128 with a piniou'129 on the shaft 130, and the said shaft 130 carries a spurwheel 131, which receives motion from a pin-. ion 132 onthe shaft 79. The rollers'108, which form a continuation of the series of rollers 108, receive niotion through the chain 133 from a sprocket-Wheel 134 on the shaft 79. provided with a sprocket-wheel for receiving thechain and is connected with the other rollers in the series by a chain-gearing;

- The operation of my improved machineis as follows: The melted glue being delivered by the valve 7 to the cylinders 8 is spreadout and formed into a thin sheet and cooled as'i-t is carried forward by the cylinders, the said cylinders being cooled by the passage of cold water through them or the application of cold water to the under surface'of the cylinders, as described in the application'for a patent The cooled sheet of glue is delivered'to the endless conveyor 9, which in turn delivers it to the series of cords 18, which carry it forward over the drum 21, where it is cut into lengths bytheknives 25. As soon as the sheet of glue comes above the table 62, thesaid table is raised by the chains 50 54,1iftihg they shoot of glue from the cords 18, The continued forward movement of the said chains 50 54 carries the table rapidly forward, at the same time tilting it, was to compel it to take a po sition parallel with the cords 19.. When the table is dropped, it leaves the sheetof glue upon the cords 19. The ,said cords 19 move forward with a velocity which-is greater than the velocity of the cords 18, thereby causing the sheet of glue to advance sufficiently to leavea space of six or eight inches between the sheet deposited arid thenext succeedingsheet. The table 62after being dropped is uickly returned to its position at the receiv-V ing end of the machine, while in the mean time another sheet of glue has been carried forward into position to be taken by the table and carried forward to the cords 19, as before The first of the series of rollers 108 is described. By carrying forward the sheet of glue from the cords 18 to the cords 19 and increasing the speed of its travel on the cords 19 suifi'cient space is left between the sheets toallow for spaces between the nets, the spacing being governed by the thickness of the netfr'a'mes, also by the distance required between the nets to'allow for the operation of the netstacker. The sheet of glue is carried forward by the cords 19 underneath the revolving cutters 39', which divide it into strips of suitable width, and the said strips are moved forward and delivered to the cords 71 In thepassage of the strips over the roller 70 the said strips are cut up into suitable lengths by the knives 69, and the sheet of glue thus subdivided is car-' ried' forward by the cords 71 to the roller 72, where it is delivered to the net 80., While the sheet of glue is'being formed, out into sheets, spaced, out into strips, and'further subdivided by being cut into small squares'preparatory to its delivery to the net-frames, and the frames '7 having been placed'in the form of a stackabove the unstacking mechanism, the netframes '8O are delivered one by one tothe end- I less chain 74 by the unstacking' mechanism 3, which operates as follows: The. stack of framesbeing'held' by the pawls 83 to engage pawls by the bars 91. The continued movements of the'cams 97' allow the bars 91 to descend, thus lowering-the entire stack of netframes, aud'at thesame time releasing the ar'ms'89 86,-all wing the sprin'g-pressed'rods 84" to move forward against the pawls-83, so

that when the secondframe from the bottom of the stack reaches the pawls the said pawls engage the notches in the frame and support the entire stack. The lower net-frame of the stack, beiug'below the device, continues its descent nntil it rests upon the endless chain 74,

which moves the frame forwardfrom beneath the stack of frames, so as to permit of another excursion of the bars 91. The'chain 7 1 and the intermittent unstacking mechanism a're'timed with reference to each other and to 'the delivery, of thesheet from the sheet separatorand subdiv'ider, so that the cords 71, may deliver a subdivided sheet. of glue to a net 80 as it passes under the roller 72, the re-- .qai'red=intermittent motion-of the uustackingmechanism being secured by the segmental 'in ion- 99 and 711 the said-wheels b I ringconneet'edwiththe same source of power thatoperates the other portions'of the machine, 'Ih'effram'es after being filled are still fcar riedfor ward until arrested by'the posts w, when they are received by the bars 91 of the stacking mechanism, which correspond to the bars 91 of the unstacking mechnet-frame'SO from the chain 74, carrying, up-

ward with the said frame the superposed frames until it is brought into engagement with the pawls 107, thus adding one frame after another to the bottom of the stack until a stack is formed of convenient size for handling. The height of the stack is controlled by the gearing connected with the endless chain 110. The said gearing takes its motion from some moving part of the machinery or. from the source of power and is timed so as to work synchronously with the unstacker and the separator and subdivider. The chain 119 is moved forward intermittently by the segmental wheel 124, the segmental pinion 123, the spur-wheel 122, pinion 121, and sprocketwheel 118. The bars 120, connected with the chains 119 on opposite sides of the machine, engage the stack of not-frames 80 and move it forward over the rollers 108 until it is engaged bythe power-driven rollers 108, which carry it away from the delivery end of the machine to be transferred to the drying-room.

Although I have described my improvement as consisting of a glue-cooler, a subdivider and spacer, a net-unstacker, and a net-stacker, I do not confine myself to this arrangement,

as the unstacker and the subdivider and spacer may be omitted, and the'gluo may be delivered directlyto the nets carried by the endless chains, and the nets may be stacked .in the manner already described.

Having thus described my invention, I claim as new and desire to secure by, Letters Patent-- 1.
