FRANK J. F AULKNER, OF LYNN, MASSACHUSET' LEATHER-DRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. t4.3,433, dated December 23, 1890.

Application filed August 11, 1890. Serial No. 361,649. (No model.)

To all whom it may concern:

Be it known that I, FRANK J. FAULKNER,a citizen of the United States, and a resident of Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Leather-Dressing Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention has for its object to provide novel means for mechanically blacking or seasoning sheep, goat, calf, and other skins; and to accomplish this object the invention involves the features of construction, the combination or arrangement of devices, and the principles of operation hereinafter described and claimed, reference being made to the accompanying drawings, in which Figure 1 represents afront elevation of the machine. Fig. 2 represents an elevation of the same as seen from X in Fig. 1. Fig. 3 represents a cross-section on the line Y Y shown in Fig. 1; and Fig. 4 represents an enlarged cross-section on the line Z Z shown in Fig. 3. Fig. 5 represents a perspective view of one of the pads, and Fig. 6 represents a longitudinal section of one of such pads.

Similar letters refer to similar parts when everthey occur on the different parts of the drawings.

In the drawings, A A represent suitable frames secured together at a proper distance apart in any suitable manner, such frames having bearings a a in their upper ends, in which is journaled the shaft 1), to which arotary motion is imparted, preferably by beltpower applied to the pulley 1), fast on said shaft. 1) is a loose pulley on said shaft, onto which the driving-belt is shipped when the machine is to be stopped. To the shaft 17 is secured in a suitable manner the pad-carrying wheel or drum B, asshown. On the periphery of said drum are secured a series of pads, each of which is preferably composed of a block 0, secured to'the rim of the wheel B by means of abracket O and suitable fastening-screws. To each block 0 is secured a sheet of rubber 0, covered with a sheet of cloth, felting, or textile or fibrous material C, as shown in Fig. 6.

C is ahollow air-spaeeleft between the block 0 and rubber O, which. serves,in connection with the rubber cover 0, as a cushion to im part the needed flexibility and yielding propensity to the pad.

I11 practice I prefer to arrange alternate pads on the opposite faces of the wheel B, as shown in the drawings, one set of which is designed for the purpose of applying the liquid seasoning to the skins and the other for the purpose of rubbing it into the pores and surface of the skins.

D is a suitable pail, tank, or vessel containing the liquid blaeking or seasoning D that is to be applied to the skins.

d is a faucet or equivalent device for regulating the flow of the liquid from the vessel D. The said vessel D is preferably supported ends of standards A A, cast in one piece or secured to the respective frames A A, as shown.

E is a flexible strap or apron, preferably secured in its upper end to the shaft D and provided at its lower end with a cross-bar E, which is held in position by means of rods or bars E E, secured in their lower ends to said cross-bar E and in their upper ends to the shelf D" or other stationary part of the machine. In practice I prefer to make the apron E only wide enough to cover the pads on one side of the rotary wheel B, as shown in Fig. 1, and said apron serves for the purpose of transferring the liquid blacking or seasoning to one set of the pads and to distribute it evenly on such pads, which is accomplished by said apron being held in contact with the rotary pads.

In front of the rotary wheel B is arranged a curved table F, secured at its ends to the frames A A, which table serves as a support for the skin G that is to be operated upon. Between the inner side of the curved table F and the outer surface of the pads there is a space sufficient'to receive the skin without contact with the rotary pads.

Opposite to the wheel B and its pads I make a cut-away portion F in the table F, adapted to receive one or more curved pressure-blocks H H, pivoted at h in their lower ends to the floor or any other stationary part, as may be most practical. Said curved pressure-blocks are manipulated for the purpose of pressing a portion of the skin from time to time against on a shelf or board D, secured to the upper the rotary pads by means of treadles ll ll, pivoted at h and having levers II" II, pivoted to links II II, jointed in their upper ends to the pressure-blocks II II, as shown in Figs. 1, 2, and 3.

The operation of the machine is as follows: The pad-carrying wheel 13 is set in a rotary motion in the direction as shown by arrows in Figs. 2 and 3, and the blacking compound or seasoning D is allowed to how or trickle out from the faucet (Z onto the rear edge of the shelf 1) or upper end of the apron or distributor E, by which one set of pads is charged evenly with the liquid compound or seasoning. The skin G is then introduced between the curved table or support i and the wheel I and by depressing the treadles II II a portion of the skin is brought in contact with the pads on the wheel 13, causing the seasoning to be rubbed onto and evenly distributed on the surface of the skin. By changing the position of the skin from time to time its entire surface is acted on by the liquid supplying and distributing pads until the whole surface of the skin is properly seasoned.

Ilavingthus fully described the uatu re, construction, and operation of my invention, I wish to secure by Letters Patent, and elai1n 1. In a blacking or seasoning machine,t-he combination of a rotary wheel having at its periphery two sets of yielding pads arranged at opposite sides of the wheel, with those in one set alternating with those in the other set, and oneset serving to apply the blacking or seasoning and the other set to rub the same into the skin, with a tank or vessel forcontaining the blacking or seasoning and delivering it to the set of pads, which apply the same to the skin, substantially as described.

2. In a blacking or seasoning machine, the combination of a rotary wheel having at its periphery two sets of yielding pads arranged at opposite sides of the wheel, with those in one set alternating with those in the other set, and one set serving to apply the black.- ing or seasoning and the other set to rub it into the skin, with a tank or vessel for containin g the blackin g or seasoning and a curved apron arranged to press against one set of the pads to evenly distribute the blacking or seasoning thereupon, substz'intially as described.

In a blacking or seasoning machine, the combination of a rotating drum having atits periphery two sets of alternating pads for respectively applying and rubbing in the blacking or seasoning, a curved, slotted, or recessed table extending partially round the wheel, the curved pressure-blocks extending through the slots or recesses in the table, and treadle mechanism for moving the blocks through the table to press the skin against the two sets of pads, substantially as described.

i. A blacking or seasoning machine consisting of a tank or vessel for containing the blackiug or seasoning, and a rotary wheel having at its periphery a series of yielding pads for applying and rubbing in the blacking or seasoning, each pad being composed of a holder attached to the wheel and an elastic sheet secured to the holder, having an external fibrous pad covering and arranged to provide an air-space between the elastic sheet and holder, substantially as described.

In testimony whereof I have signed my name to this specificatioinin the presence of two subscribing witnesses, on this 5th day of August, A. D. 1890.

FRANK J. FAULKNER.
