SPECIFICATION forming part ofReissued Letters Patent No..10,875, dated October 18, 138').

' Original N0- 3 9.39l, dated Mala-h l5, Ii-YHT. A ppliuation for Il-inslm lilnd Juno 2], last. Si-rial No. l-ILJLIIL .To aZ Z whom it may concern:

Be it known that I, DEMING J ARVES, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Glue-Cutting Machines; and I do hereby declare thatthe following is afull,

clear, and exact description thereof, reference being had to the accompanying drawings, which form; apart of this specification.

This invention relates to new and useful improvements in glue cutting machines; and the invention consists in the peculiar construction and combination of the parts, all as more fully hereinafter set forth.

' In the drawings which accompany this specification, Figure 1 is a vertical longitudinalsection of my improved machine. Fig. 2 is a crosssection of the same on the line a: a: of; Fig. 1. Fig.3 is a side elevation of one end. Fig. 4 is a plan of a section of the carrier.

A is a horizontal glue-cake carrier, open at the ends and of rectangular cross-section, corresponding in size with the crossscctiou of the glue cakes to be carried. Itssidcs'are formed by two parallel rows of vertical rolls, .3, and the top and bottom are formed by two endless belts, C C, respectively. That portion of the belt 0 which forms the bottom of the-gluccake carrier is supported on a row of horizontal rolls, D, and that portion of the belt 0 which forms the top of the glue-cake carrier is sup ported on the back by a similar row of' horizontal rolls, E.

The vertical rolls B are suit-ably journaled on the inside of the parallel frames F, which form the sides of my machine and support the operating parts thereof.

The horizontal rolls E on top of the glue cake carrier are suspendedby means of hangers G from the top of the frames F, and the horizontal rolls I) on the bottom of the gluecake carrier are journal'ed upon standing blocks H, secured on top of the horizontal beam I. This latter beam is supported vertically adjnstably on screw-supports J and laterally by the side frames, F.

The screws J are all provided with suitable worm-gear, \V, actuated by a common shaft, L, and hand-wheel M, by means of which'they may all be simultaneously actuated to raise or lower the beam I, with its row of rollers supported thereon.

-ing-scrcws O.

N N are glue knives or wires placed transversely across the path of the glue cakes 1n the carrier. They are formed of llatstccl bars I or wire secured at the ends to the side frames of the machine and provided with the strailn Tin-so knives or wires pass at suitable distance apart through the interstices in. the side rolls, which, bring preferably placed together as near as possible; have tohc notched to clear the knives or wires.

The knives are placed in an inclined series from front to'rear, beginning near tlieln')ttoi|i at the frout'ond of the carrier, and with an equal rise step by step to near the top of the rear end, the vertical distance from knife to knife being about one-eighth of an inch---l'.he

usual thickness into which glue is cut for the Should an increased thickness bcdcmarket. sired, a suitable number of knives is removed. In practice the cakes of glue are placed one after another upon the front cud of the lower carrier-belt, U, which for that purpose extends out in frontandhasthc guide-plates l. secured at the sides. This bclt carries the cake into the carrienbox, where each cake is pressed into shape andv subjected to the action of the knives, so that by the time it is discharged atthe rear end of the machine intoasuitablcclevator it is all cut up into layers, which, however, still adhere to each other.

It will be understood l hat the spirit of my invention consists in the peculiar construction of my carrier, which enables me to nnikc use of a continuous feed, and thereby produce a glue-cutting machine of a capacity herctoforc unknown.

,The parts which form the calm-carrier proper comprise the top and bottom rolls, l) l),- and the carrier-belts CO. The vertical rolls l are merely intended for guide-rolls and to prevent the cutting knives or wires from tearing the edges of the glue cakes while the knives are pressing through, and the entire or partial omission (leaving a few rolls at the front for guiding) of the. vertical rolls will not interfere with the successful operation of the machine, as there will be but little waste if the cuttingwircs are relatively line and well strained.

-\Vliat I claim asmy invention is- 1. 'In a glue-eutting machine, theieombina tion of an upper and lower bcd,each formed of a series of horizontal rolls, and ofj'wo carrierbelts traveling in the same direction, one pass mg over the lower bed and the other beneath the upper bed, and a series of cutting-wires, substantially as described.

2. In a glue-cutting machine, the combination of an upper and lower bcd,caeh formed of a series of horizontal rolls, the-lower bed of rolls being vertically adjustable, and two carrier-belts traveling in the same direction, one passing above the lower bed and the other be-. low the upper bed, and a series of cuttingwires, substantiallyhs described.

3. In a glue-cutting machine, thecombination, with'thc frame, of the series of lower rolls,

I), forming a bed, and the series of upper rolls,

ll, forming a bed, of the hangers G, suspending the rolls of the upper series from the frame, and the blocks H, supporting the rolls of the lower series, and two carrier-belts traveling in the same direction, one passing over the lower bed and the other under the upper bed, and a series of cutting-wires, all substantially as de-.

scribed.

4. In a. glue-cutting machine, the combinatiou, .witlrthe lower and upper series of horizontal rolls, forming an upper and lower bed,

of two oarrier bclts passing, respectively,'abov e and below said series of rolls,and of an inclined series of lcnives or cutting-wires arranged between saul carrier-belts, substantially as de scribed.

5. In a gluecutting machine, the combination, with the frame, of an upperseries of horizontal rolls and alower series of horizontal rolls, said rolls forming, respectively, an upper and lower bed for two carrier-belts, of an independent support for the lower rolls, and suitable screws'and worm-gear for vertically raising and lowering said support, substantially as described.

6. In a glue-cutting machine, the combination of an open-ended box, the top, bottom,and sides of which are formed b 57 rolls, and of two carrier-belts passing through said box upon opposite sides, substantially as described.'

7. In a glue-cutting machine, the combination of four rows of rolls, forming the four sides of an open-ended horizontal box, and of two endless carrier-belts passing through said box, one over the bottom rolls and the other under the top rolls, substantially as described.

8.v In a glue-cutting machine, the combination of the four rollsB B D E, forming the sides of an open-ended box, the carrier-belt 0, passing underneath the top rolls, and the carrierbelt 0, passing over the bottom rolls and projecting in front beyond the carrierbox, substantially as described.

9. In a glue-cutting machine,- the combination of the carrier-box A, the knives N, the side frames, F, the vertically-adjustable bed I, the screw-supports J, the worm-gear W, the shaft L, and wheel M, all arranged and operating substantially as described.
