:carrying chains.

My invention comprehends improvements in the operation of forming glue into sheets' of jelly for the purpose of 'being dried as heretofore conducted, and reduces the cost of manufacture between the periods of the ren-A dering aud the drying of the glue.

Machinery embodying my improvements is represented in the accompanying drawings and hereinafter described, the'particular subject matter claimed as novel being hereinafter definitely specified.

In the drawings, Figure 1 isa central vertical longitudinal sectional side elevation through a preferred form of machine embodying my improvements. Fig. 2 is acentral vertical transverse sectional Ielevation through the cooling cylinder shown in Fig. 1, and through an ice chamber employed in connection therewith,an associated pump and pipe connection being shown' in elevation. Fig. 3'is a fragmentary end elevational View of the driving drum and of the sheet carrying apron, the View beingtakenvfrom the left hand end of Fig. 1. Fig. 4 is a similar View taken from theright hand end of said Fig. 1, of the knife shaft knife and knife drum, showing also in transverse section the endless net carrying chains and one of the nets. Fig. 5 is atransversc central vertical sectional. elevation through a modified form of cooling cylinder.

Fig. 6 is a fragmentary side elevational detail of a train of gearing which l find it convenient to employ for the actuation of the knife vshaft the sheet carrying'apron and the net Fig. 7 isa fragmentary side sectional detail to an enlarged scale of the inclinedchute, and of a portion of the cooling cylinder.

Fig. 10 is a transversev central verticalsectional elevation, through a modified Fig. 11 is an end elevational view of a modification of the trough employed in connect-ion with the reservoir and adapted to supply liquid glue to the chute.

of the same. Similar letters of reference indicate correspending parts.

Fig. 12 is a side elevational View A Referring now first to the lirst seven iigures of the drawings, A is a tank or reservoir provided with a suitable outlet faucet a, for containing liquid glue fed to it in any preferred manner, as, for instance, through the supply pipe ax. This tank is supported in any'suitable manner, as, for instance, upon the frame work Ax.

is a cooling cylinder, preferably formed as av casting having a smoothly turned peripheral face. This cylinder is conveniently formed with two concentric cylindric webs, of which the outenb, is the glue receiving and carrying surface, and the inner, bx, a web concentric with the outer Web, and disposed sufficiently apart from it to occasion the formation between the webs of an annular cooling and circulating chamber b laterallyinclosed by radial flanges b2 having peripheralfextenso as to form edges to prevent the liquid glue v'applied to the surface of the outer web from escaping laterally from oif it.

Bx is a hollowshaft formed as a part of the cooling cylinder, upon trunnions hier eXtensions of which, the cylinder is mounted for rotation in suitable bearings b4. The shaft is intern ally longitudinally divided by a partition h5 into two chambers which in the construction under discussion respectively communicate with the respective trunnions, and one of which, through a series of hollow spokes h6, communicates with the annular cooling chamber, and the other of which through a corresponding series of hollow spokes simi-4 larly communicates with said cooling chamber at a point preferably diametrically opposite to the point of communication of the spokes first referred to. It is obvious therefore that cooling fluid (liquid or gaseous) admitted through one trunnion will be caused to pass to the cooling chamber, to circulate throughout it, and to escape from it through the other trunnion. Solid spokes 1f' conveniently complete the structure of the cooling cylinder as a whole.

C is a glue distributing trough, preferably of a length correspondent with the breadth of the face of the cooling cylinder, conveniently longitudinally disposed in parallelism with the axis of the said cylinder, and supported upon the frame-work in such relation to the reservoir as to receive through the outlet faucet a. a supply of liquid glue. In the bottom of this trough are a series of discharge orifices c, which may be in the form of depending nozzles of uniform size and equally spaced longitudinally, through which the liquid glue escapes from the trough upon an inelined chute D the lower or outer edge of which is of the breadth of the carrying face of the cooling cylinder and rests thereupon preferably at a horizontal line not more than forty-five degrees below the top of the cylinder.

A closed pipe cX having the depending nozzles c' and communicating through a suitable regulating valve c2 with the reservoir A, may, as shown in Figs. Il and 12, be substituted for the trough C.

The inclined chute, as clearly shown in Fig. 7, is preferably hinged at its upper edge to the framework so as to rest as to its lower edge by its own weight upon the surface of the cylinder. The chute is inelosed at its sides.

The cooling cylinder upon the external surface of which the liquid glue is deposited from the reservoir through the medium of the trough and chute, is of the construction al# ready explained in order to permit of the continuous passage or circulation through it of ice water or cooling duid, and in Fig. 2 I have indicated a convenient device for establishingandmaintainingsuehacirculation. This device is conveniently composed of a chamber E, water tight at the bottom and adapted to contain ice, and of a pump F adapted through a suction pipefleadingout from the lower part of said chamber to suck the ice water from said chamber and force it through the force pipe f into one of the trunnions of the cooling cylinder through the cooling chamber of which it circulates and through the other trunnion of which it is, after its circulation, forced into a discharge pipe f2 leading back into the ice chamber. The suction pipe should start from the bottom or the lower portion of the ice chamber. The discharge pipe may deliver its contents either int-o the lower part of the ice chamber as shown or above the ice. The force pipe into and the discharge pipe from the cylinder make tight communication with the trunnions of the cylinder by the stuiiing 'boxes fx. The pump may be of any preferred character. A drain pipe f3 is provided for the escape of the su rplus water as it accumulates from the melting of the ice.

G is a driving drum or roller, suitablyhoused for rotation at the proximate end of the framework of the machine below the trough and chute, and in axial parallelism with and near the periphery of the cooling cylinder.

` (lX is a driven drum or roller, parallel with the driving drum, but preferably of smaller diameter and disposed at the distant end of the framework. Its upper or carrying face is in the construction under discussion shown as on the same level with the upper face of the driving drum. Intermediate between these drums are a series of idler rolls g in axial parallelism with each other and with both the driving and the driven drums. Both the driving and the driven drums, and, if desired, the idler rolls, are circumferentially channeled with a series of correspondent grooves g (see Figs. 3 and 4) which receive a series of endless cords or tapes II, together forming an endless sheet-carrying belt or apron-conveniently led in the manner shown in the drawings around the driving drum the idler rolls and the driven drum, and which prevent the projection of said cords above the surfaces of the drums and rolls.

Many devices for imparting motion to the driving drum and the cooling cylinder may be resorted to. I iind it convenient to provide a motor shaft I deriving its motion from any suitable source of power and equipped with a toothed driving pinion z' in engagement with a toothed driven spur wheel 72X applied to one of the trunnions of the cooling cylinder' and adapted to drive it, and also equipped with a pulley i2 from which a belt s runs to the driving drum G or to a driven pulley e, Fig. 6, applied to its shaft to drive said driving drum.

The foregoing is simply, as stated, a convenient connective driving gear which may be replaced by other driving mechanism. Whatever gear be employed, it should be of such character as to speed the periphery of the driving drum in slight excess of that of the cooling cylinder.

gi is what I term a knife drum, it being, as shown in Fig. Il, grooved in correspondence with the driving and the driven drn ms to permit the passage of the cords with respect to it but below its surface. Immediately above the knife drum is mounted a rotating knife J, conveniently formed as a knife blade radially projecting from the surface of a shaftj mounted in suitable bearings in axial parallelism with the knife drum, the edge of the knife being parallel with the axis of its shaft. As the knife shaft j is caused to rotate, the knife or blade is caused at intervals to come down upon the upper surface of the knife drum. The rotation of the knife shaft may be conveniently eil'ected in many ways. I find it easy to effect it by an endless chain IIC jx passing 'over a chain wheel 3'7 Fig. 4, on the knife shaft j, and taking its motion from al chain wheel j, Fig. 6, on an idler pinion shaft j2 upon which shaft is also mounted an idler toothed pinion j?? inA engagement with a master pinion ji uponrthe shaft of the driving drum, as shown in Figs. l and 6. The idler toothed pinion 7"3, taking its motion from said master pinion, also serves to transmit it to a chain wheel pinion ji upon' a chain wheel shaft lo housed in the framework, and upon the respective ends of which are mounted a pair of counterpart chain wheels k which correspond in their dimensions and mountings to a counterpart pair of counterpart chain Wheels kx upon a shaft 7a2 in parallelism with thev shaft 7c butv at the distant end of the framework. The lateral distance apart of the wheels forming the respective pairs of chain wheels la kx is preferably correspondent with the breadth of the face of the cooling cylinder.

The shafts of 'all the rolls, pinions, drums, and wheels, hereinbefore referred to, are in parallelism. f y

Thepairs of chain wheels [a kx carry two parallel endless net-carrying chains K, which at uniform intervals are provided with adjacent parallel pairsof transverse guttered carrying bars k3, so spaced as to be adapted to receive o'r-have slid into them, the depending legs Zot the net frames ornets L,-the arrangement being such that as each net frame is successively applied to the carrying bars of the netl carrying chains it is closely behind the preceding frame or net. The longitudinal distance apart of the carrying bars of i Vthe endlessl net carrying chains bears relation to the length of the nets, the latter being such as convenience `for handling may dictate. I

To the end that each sheet of glue may, in

l Y the operation of the machine, whereof here-l inafter, be of the length of the nets, the edge 0f the knife is at such a distance from the center of the knife shaft and the revolutions of the Yknife shaft are so speed'ed as to occasion the descent of the knife 'upon the knife drum at .intervals of time correspondent with those which in the operation of the machine elapse between the longitudinal passage of the front and back edges of a net past a given fixed point, for instance, the knife drum of the machine. -In other words, the rotation of the knife is timed to coincide with the travel of the nets. During the momentary interval of contact of the knife with the knife drum the sheet glue passingov'er the drum upon the breast of` the sheet carrying apron, is transversely severed.4 v

M is a net wagon or truck arranged and l adapted to be `broughtup to the distant chain wheels, and to receive a series or stack of nets from the chains, as shown in Fig. l. lt will be observed that, as stacked, the nets' rest upon each other through the interventionof their depending legs'wherebya circu lation of air between the nets constituting a' stack is permitted. Having thus described .machinery embodying my improvements, its operation is'as follows: Glue,while still warmV and in the liquid state, is supplied to the reservoir, and the pump is then set inaction to occasion a circulation of the cooling fluid into and out of -the cooling cylinder, with the result that the carrying face of said cylinder is cooled and y kmaintained in a cold condition so long as the pump is kept in action to maintain the circulation through theI cylinder, and at the same time the motor shaft is caused to rotate and drive the cylinder in the direction of the arrow. The sheet-carrying endless apron, the knife shaft, and net-carrying endless chains, will also through the connective driving gearing all be caused to move in the direct-ion of the arrows respectively shown as applied to them, and will be maintained in motion. The outlet faucet from the tank being then opened sufficiently to give the proper supply, the liquid glue will flow into the trough and thence upon the chute in constant streams which will merge together in iiowing over the chute and form a sheet of` uniform thickness distributed evenly across the face ofthe chute and evenly across the carrying face of the cooling cylinder, by the revolution of which TOO great as to prevent it/from being carried forward and upward without the necessity of a tight contact to prevent leakage downward between the edge of the chute and the face of the cylinder or the necessity of any contact at all between' the sides of the chute and the cylinder. The delivery of the glue high enough on the cylinder to'obviate the necessity of havingla tight contact of the glue delivering device with the cylinder, or any contact at all of its sides with the cylinder, orof having the cylinder dip into a vessel containing the liquid glue,is one of the features of my invention that distinguishes it from others having the same general purpose, in which the glue is either taken up by the cylinder from a tank placed below itand into which it dips, or in which the cylinder takes the glue from a delivering device placed about level with or lower than the axis, and which, because it is so placed, requires to be tightly pressed against the face of the cylinder, and

sometimes to have packing'arrangements to prevent leakage.

backward is less, a thicker sheet of glue`can be taken ontothe cylinder and hence upon n Bydeliveringthegluehigh on the cylinder where its tendency to run' point about opposite tothe driving drumf an attendant, standing in a favorable posi tion, reaches over the drum, and, while the apparatus continues in motion, dexterously parts or detachee the advance edge of the sheet from the cooling cylinder and overlays it upon the drum, the adhesion of the sheet to the surface of the drum being suiiicient `to occasion the initial stripping, which is thereaftercontinuous. ln practice, the speed of the i moving parts being under complete control,

the apparatus is slowed down during the performance ofthe operation above referred to.

The advance edge of the sheetof glue having been led off of the face of the cooling cylinder on to the driving drum and carrying face or breast of the endless cord apron, the

friction of the glue upon the drum and cords will be sufficient to give it the necessary adi hesion to them, to enable them in moving forward, to strip the glue in a continuous sheet from the cylinder as long as the operation is kept up. As the chilled sheet adheres slightly tothe face of the coolingcylinder,some tension is required to strip it olf, and the sheet being elastic this tension stretches it somewhat. lf, i therefore, the periphery of the driving drum E should `move no faster than that of the `cooling cylinder, the glue, being stretched as it is received on the drum, would not be pulled 0E of the cylinder as fast as it would be car- 1 ried upward byitin adherence to its surface, and the line of parting between the sheet and the cylinder would in consequence be gradually carried upward until the sheet would encounter the under face of the chute, elevate it, and foul with the liquid glue. To obviate this result which would manifestly render the operation of the machine impractical, the driv' ing drum is speeded to an extent suliicient to cause its surface to move suliiciently faster than the surface of the cooling cylinder to insure a tension adequate to strip the sheet from the cylinder before it reaches the chute. The movement of the sheetcarrying apron occasions the advance of the sheet from the driving drum to between the knife shaft and knife drumand its further passage beyond them from off the apron to and upon the carrying face of the nets, which, in the travel of the net carrying chains, are caused to successively present themselves beyond the driven drum and in position to receive the advance portions of the sheet in the forms of sections of uniform length, correspondent with the length of the nets and formed by the dividing action of the knife, the timing of the ents of which is such, as explained, that `each cut is made in the portion of the sheet lying between theadjaeent edges of the successive knets in place' upon the carrying chains. rPhe nets are applied to the carrying chains one after another by attendants, who, standing at the side of the machine, slip them on the chains transversely of the direction of their travelrethe depending flanges of the net frames being, as already explained, `engaged with the carrying bars of the chains, an operation easily performed while the chains are in motion, as soon as the operators become dexterons. Each net with the divided sheet upon it, as it reaches the end of the carrying chains, is manually removed by operators and placed upon a net-carrying wagon, until astack has been formed which is removed upon said wagon, and succeeded by another stack erected upon another wagon run into the place of the first wagon.

The subsequent operation of drying the sheets of glue upon the nets by air at normal temperature or artificially heated, is the usual operation with which those skilled in the art are familiar.

Such being a description of a good form of machine embodying my improvements, I have in Fig.8 represented a type of variation in which the endless sheet-carrying apron is dispensed with andthe sheet of glue stripped from the cooling cylinder and deposited directly upon nets in placeof upon the nei-fearrying chains. In this construction the rela tive arrangement of the reservoir, trough, chute, and cooling cylinder, are the same as in the construction hereinbefore referred to, but the sheet is stripped from the cylinder by the aid of acounter-balanced pivoted stripper N bearing against the face of the cylinder and possessed of an edge so dull as not to cut the sheet. In this construction the endless netcarrying chains are arranged below the cooling cylinder and provided at intervals,bein g those between adjacent carrying bara-with transverse knives 7a4 of such height as to project slightly above the carrying faces of the nets when in place upon the chains, and to serve in conjunction with a pivoted knife drum g5 to occasion the transverse severance of the sheet into sections correspondent with the length of the nets, the weight of theknife drum alone being suiiicient to occasion the complete severance of the sheet. In this con- IOO struction the motor shaft I is provided with a represented in Fig. l, is arranged at a sharp.v

' downward incline, instead of being in parallelism with the netecarrying aprons as in the construction represented4 in Fig.` 1. The object of this varrangement which is not in itself essentially different from thatof Fig. l, is to permit of the arrangement of thenet-carrying aprons in the manner 'representedin the apparatus of Fig. 8,-that is to say belowv thecooli-ng cylinder,` to the end thatin anf apparatus ofthe characterof that of Fig. 8 the nets v'may be 'introduced beyondor in advance of the coolingcylinder instead of beneath theA sheet-carrying apron. In Ithis construction,

the gear for driving the cooling cylinder, thev sheet-carrying apron, and the knife drum, is essentially the same asin Fig. l, but the netcarryingapronsv are driven by a'beltO applied-to 'a pulley OX lon the. shaft'lc of the chain wheels,which belt derives its movementv from .a pulleyO2 onthe motor I shaft I.

VIn Fig. I have represented as a substitute for thecooling cylinder B.y o f the apparatus of Flgsfland 2, ak hollow drum B2 constituting 'z 5 atight cylindric tankV adapted to revolve on hollow trunnions and provided with'intern'al disks, shields, or` .diaphrag-ms, b8,.of lessdiameter than-the interior'diameter of the drum, 'f and -so concentri'cally Vsupported by radial brackets b9 as to occasionfthedeflection ofv ,a uid entering one trunnionpto theperiphery of thefdrum' and through or'across the interior thereofibefore it can escape'from the opposite trunnion.

In Fig. 10 I'have further representedasa substitute for theotherforms of cooling cyl- I inder, a hollow drum B3 in which the force" pipe f and the discharge pipe f2 are both arl ranged to open through'a single trunnion b5, the forcepipe passing axially through'the.

. drum and discharging beyond, a disk or dia'- -f phragm b1@ corresponding to one ofthe diaphragms in` the/drum of Fig. 5. In this construction the other trunnion becomes a solid gudgeon, h. v

In any form of cooling cylinder selected for employment, it is of theessence of the inven' tion that provision bevmade to permit of the continuous circulation of the cooling medium water.

By the term cylinder as applied to the cool-' ing dr.um,I include any prism or drum of po- ;lygonal circumference wherewith the opera-- pressure and divested ofl the heat thereby developed, and which when released from pressure inside the cylinder thereby becomes cold,in the case of a gas' bysimple expanA cylinder tothe refrigerator, shouldbe the `same'fluid continuously used wheneverlts l ration,- in either case according to principles 1n` common kuse for refrigerating purposes.

ing of the ice should be allowed to escape,'so that the whole capacity of the ice to absorb in melting (except losses by radiation,v dac.) will be utilizedin cooling the glue. If-upon the and that onlythe surplus water from the meltother hand, a continuouslynew supply of wa-v ter should be [irs't passed through the ice,thenl through thecylindenand 'then be finallyvdis-I carded at a temperature lower than it had at its introduction into theice receptacle,.the"

meltingY of the ice that would be required to -f reduce the temperature of the water at its introductioninto the ice .receptacle to that at its discharge from' the cylinder,y wouldfbel waste thatwould be saved by using the same fluid.v repeatedly. The same economical con- Siderations applywhen other artificial refrigf eratingapparatus is employed, that is tovsay,

the'iiuid for transmitting the heat-from the temperature at its discharge from the cylinder is lower than that .at which itwould en.- ter the refrigerator inthe case of a continuously new supply. .These considerations, manifestly, have no applicationwhen naturally coldlwaterisused. j Whatever, however, the medium maybe, it -is of the essence of :the invention that it be caused lto circulate into and out of the interior of the coolingcyli1ider,in order to maintain the carrying vface of said cylinder constantly cold. Y f

I employ the terml F glue generically, to include gelatine and compounds composed principally of glue or gelatine. l e It is proper to state that a pump is probably the best device for occasioning circula- IIO tion of ythe cooling iiuid through the cooling Y 'cylinder and to and from the vchamber in which the cooling medium, whatever it may be, is contained, but that other devices may be employed to occasion such circulation,-

and also to state that while I prefer to employ iceas the refrigerating material lfor cooling water as the preferred cooling `iiuid,-yet that other refrigerating materials or processes may be employed for the cooling of the water or other fluid in a chamber of the character of the ice chamber E, or in another vessel, receptacle or reservoir being the equivalent for the purpose, of the chamber E; It may also be' added that-while I prefer to employ in. con'- nection with the net-carrying apron'the 'sheetcarrying apron shown in Fig. 1, yetvthat said sheetLcarryingapron is not of the essenceof the invention; andfurther that while the preferred means for supplying liquid glue to the carrying surface of the cylinder are the tank-trough and chute set forth, yet that other devices may be employed as their equivalents; and,

still further, that While the driving drum` shown 1n Figs. 1 and 3, is aconvenient means .Y 'for stripping and for carrying-olf from said cylinder the sheet of glue, yet that other devices operative in a similar manner may be substituted in its stead. In likev manner it may be remarked that the rotating knife as a mechanism for dividing the sheet trans-` versely into sections may be replaced bya vertically moving or reciprocating knife or its equivalent.

As already stated, the cylinder must he so constructed that the water or other cooling medium may be introduced into and with i of jelly, the following elements in combina tionz-a hollow revoluble cooling cylinder through which a fluid refrigerant is caused to circulate,a feed forsupplying liquid glue to the carrying surface of said cylin der whereon said glue is congealed into a shcet,-and a surface which travels ata speed superior to that of the peripheral surface of the cylinder and strips the sheet from said cylinder,*sub stantially as set forth.
