PUTTING-OUT MACHINE.

SPECIFIC-ATION/,forming part of Letters Patent No. 299,701, dated June 3, 1884. Application filed February 1l, 18S-l. (No model.)

To @ZZ whom/it may concern:

Be it known that I, JOSEPH W. VAUGHN, of Peabody, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Putting-Out Machines, ofwhich the following is a description sufficiently full, clear, and exact to enable any person skilled in the art lor science to which said invention appertains to make and use the same, reference being had to the accompa-A nying drawings, forming a part of this speci-A ication, in which--V Figure, 1 is an isometrical perspective view of my improved machine; Fig.- 2, an enlarged perspective view of a section of one of the iianges, showing the method of attaching the iianges to the roller, and Fig. 3, aview showing the arrangement of the ilanges on the roller.

LikeV letters and figures of reference indicate corresponding parts in the different iigures of the drawings.

My invention relates to that class of machines which are used in the manufacture of leather for putting-out, scouring, fleshing, and unhairing the hides and skins; and it consists in a novel construction and arrangement of the parts, ashereinafter more fully set forth and claimed, by which in some respects a more desirable device of this character is produced than is now in ordinary use.

The nature and-.operation of the improvement will be readily understood by all conversant with such matters from the following explanation In the drawings, A represents the upright frame-work, and B the inclined framework, these constituting the body of the machine. The upright frame-work consists of the long standards a and short standards f, connected by the beams b and rods d. The inclined frame-work consists of the side rails, g, and

with the main driving-pulley D and loosepulley E, and at the other with the fast-'pulleys G H. A carriage or table, J, is disposed on the frame-work B, being fitted to slide longitudinall y on the ways 40, attached to the side rails g. The table is provided with side rails, m, which rest on said ways and project upwardly or forward of the center of the table proper, as shown at t', and attached to the inner sides of these rails are toothed racks e.

Disposed horizontally near the center of the frame-work B there is a shaft, K, carrying at its outer end the fast pulley L and loose pulley M, and between the rails g the pinions Z and small elongated rollers n, the pinions being adapted to intermesh with the racks z, beneath the side rails of the table J.

. Projecting upwardly from either of the rails g, near the shaft K, there is a standard, j, and pivoted horizontally, near its center, in either of said standards, in parallelism with the rails g there is a lever, N, a counterbalance, o, being suspended from the upper or rear end of each of these levers.

Journaled horizontally in the levers N, between the forward ends of said levers and the standards, j, there is a shaft, t, carryingaroll, O, provided around its periphery with a series of flanges, 25, as hereinafter more fully described. The shaft t has one of its ends eX- tended beyond the frame-work B, and is provided with a fast pulley, l?, which is connected with the pulley G by the belt r, the pulleys H L being also connected by a belt, w.

A rocker-shaft, Q, is disposed in the rear ends oi' the side rails, b, being provided at its outer ends with arms e, and near its center with the treadle-B. The lower or forward ends. of the levers N are connectedwith the outer ends of the arms c by means of eXtensible spring-rods y, so that when the foot of the workman'is placed on the treadle B the action of the weight o will be overcome and the roll O depressed, the weight being sufficiently heavy to keep the roll elevated, so that the table J may pass beneath it without coming into contact therewith when the foot is removed from the treadle A rod, 2, provided with4 an upwardly-proj ecting stud, 3, hasits inner end pivoted at 4 to a bracket on one ofthe rails g, its other end passing through a mortise, 5, inthe opposite rail and jointed to a rod, 6. A rod, 7, arranged in parallelism to the rod 2, has its inner end pivoted at S to one of the rails g, its other end passing through a mortise, l0, in the opposite rail, and being jointed to the rod 6.

A bracket, 12, projects from the standard af, and pivoted thereon at 13, is a bell-crank lever, 1i, having its inner end jointed at 15 to the rod 6, and its opposite end provided with studs 16 between which the belt uw passes, the rods 2, 6, and 7 and lever 11- constituting a shipping mechanism for said belt.

A horizontal]y-arranged har, T, is suspended between the projections 'i of the side rails, m, by means of the lugs 17, the lugs having their upper ends pivoted to said projections at 1S.

Projecting downwardly from either end of the bar T there is a bar, 19, having its lower end curved, as seen at 20, these bars being connected by the cross-rod 21.

Attached to the under side of the lower cross-rail, l1, beneath the table J, there are two downwardlyprojeeting studs, 22, these studs being arranged at the same distance from the side rails, y, as the bars 19.

A brush, 24C, is supported in the forward ends of the levers N, its teeth or bristles being so arranged as to be in constant contact with the roll O.

The flanges 25 are preferably composed of brass, composition, or similar metal, and are secured to the body of the roll by screws passing through the laterally-project-ing ears 26. These iianges start at the center 27 of the roll and pass spirally around it to either end, and are irregular in their formation, as illustrated by a plan view in Fig. 3, in which the dotted line 2S represents the central axial line of the roll O; 25, the flanges, and the dotted line 27 the line or point from which the flanges radiate or start. The first section, 29, stands at a greater angle to the line 2S than the second section, 30, and the third section, 31, stands at the same angle as 29 and in parallelism therewith, while the section 32 stands at the same angle as 30, and so on through the series. The object of this peculiar construction and arrangement of the iianges on the roll is to put out the hide or skin both laterally and longitudinally, or sidewise and lengthwise, the sections 29 and 3l acting to scrape and stretch the skin lengthwise, (or from the center t0- ward the sides of the table,) and the sections 3() and 32 sidewise, (or from the rear toward the front of the table,) thus performing the work much more perfectly than would be possible if the flanges were straight or segments of a true spiral. Each of the flanges may be formed in a single piece or in several pieces, as preferred, or most convenient and economical; and the ears 26 may be employed on one or both sides of the iiange, as desired.

In the use of my improvement the hide or skin to be put out, fleshed, scoured, or unhaired, as the ease may be, is placed on the table tI with its upper edge overhanging the upper edge of said table, a proper roll for the 7o work to be performed having been mounted on the shaft T. The bar 7 is then moved to ship the belt w onto the fast pulley L, there- Aby causingthe table to pass upwardly under the roll O. As the table advances, carrying the suspended bar T, the bars 19 will be brought into contact with the rollers mand ele-r vated or swung upwardly beneath the table, causing the bar T to be brought into contact with the overhanging portion of the skin, and SO firmly clamp it between said bar and the upper edge of the table. The table continuing to advance, the skin now passes under the roll and is brought into forcible contact therewith by means of the treadle R, acting on the levers N, and the work performed in a manner which will be readily obvious without a more explicit description. XVhen the table has passed beneath the roll far enough to bring all parts of the hide or skin into contact there- 9o with, it strikes the stud 3 on the bar 2 and ships the belt u? onto the loose pulley M, and at the same time the foot of the workman is removed from the treadle R, thereby permitting the table to descend by gravitation to the position shown in the drawings, preparatory to repeating the operation. As the table descends when the bars 19 have passed over the rollers n, their curved ends 20 are brought into contact with the studs 22, thereby'iorcing 10o the `bars downwardly and releasing or unclamping the hide or skin. from between the bar T and edge of the table.

The roll O rotates as indicated by the arrow, or in such a direction as to cause its iianges to oppose the passage ol' the hide or skin beneath it.

The brush 2i prevents the water and particles of flesh, hair, de, taken up by thcilanges 25 from being carried over the roll and brought 1 1o into contact with the finished portion of theA skin beyond it.

The table is covered with a thick sheet of rubber, 42, over which there is placed an outer covering of leather', 43, so as to render it I I 5 slightly yielding, and thereby prevent the roll from injuring the skin. A stout coiled spring,

33, is also introduced in either of the rods y,

and another, 34, at cach of the pivots j of the levers N for the same purpose, but the springs I 2o may be omitted, i'f desired, although I deem it preferable to use them, more especially those in the rods y.

Instead ot' the roll O any well-known form of roll for the same purpose may be employed, I 2 5 and, likewise, instead of the bar T, any wellknown device for clamping the hide or skin may be used, if desired.

A guard, 35, is attached to the foot of the table, to prevent the water expressed from the 13o skin from running down onto the clothing of the workman, a channel, 36, heilig provided to drain it off at either side ofthe machine.V

Buffers 37, composed of rubber, are also pro- ,f zeavol l 3 vided, against which the table strikes when it descends from the upper part of its course, as described.

It will be understood that the flanges 25 are to be constructed with sharp, angular, or rounded edges, in accordance with the work they are required to perform, and are to be changed as may be found necessary.

By inclining the table J, as shown and described, the water runs off readily from the hide or skin, and it is always in a position to be inspected by the workman. The machine may be adapted for light or heavy Work, and requires but one person to operate it.
