FUR CLIPPING AND UNHAIRING MACHINE.

SPECIFICATION forming pm of Letters Patent No. 309,878, dated December 30, 1824..

Application filed August 14, 1884.

the fur clipping and unhairing machine for which United States Letters Patent No. 275, 07 7 were issued to me on the 3d day of April, 1883,

consists in the combination, with a strip over which the fur to be clipped is passed, knives for cutting off hairs of the fur, and an airforcing apparatus, of combs or strips for holding down some of the hairs that have been laid down by the current of air, which combs are so arranged that they will be first moved toward each other and then moved downward by a suitable mechanism.

The invention consists in various parts and details and combinations of the same, as will be fully described and set forth' hereinafter.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal sectional elevation of my improved fur clipping and unhairing machine, showing it provided with my improvements for operating the comb. Fig. 2 is a side view of the mechanism for operating the combs, showing the combs drawn toward each other. Fig. 3 is a like view showing the combs drawn toward each other and lowered. Fig. 4 is a sectional plan view on theline 00 :17, Fig. 2. Fig. 5 is a cross-sectional viewon the line ;I y, Fig. 4.

The combs A aresecured at each end to the upper ends of upright plates B, provided in their upper and lower ends with transverse slots 0, through which pins D, carrying rollers, pass into a plate, E, held to slide vertically in a recess, F, in the side frame, G, of the machine. The plates B are adapted to (No model.)

slide toward and from each other on the plate E; but they cannot slide vertically on the said plate E. The plate E can slide vertically in the recess in the frame Gr, but cannot slide laterally. A bent lever, H, pivoted in the machine-frame, has its rear end resting on a cam, J, mounted on a shaft, K, which rear end of the lever H is pressed on the cam J by a spring, J, secured to the leverH and to the machine-frame.

To the lower front end of the leverH an upwardly-projecting connecting-bar, L, is pivoted,'to which links M are pivoted, which have their opposite ends pivoted to the sides of the two plates B. Theplate Eis drawn up ward by a spiral spring, N. The fur to be clipped or unha'ired is stretched over a plate or board, a, which is located between and be low the combs, and the upper edge of the said plate or strip is so arranged in relation to the combs that when the combs are drawn downward and toward each other so far as possible the toothed edges of the combs will be almost in contact with the upper edges of the said plate a. The current of air is produced in a blower, T, provided with a valve, U, in its spout T", below which spout a sliding nozzle, V, is held, which extends the err tire length of the plate a, over which the fur is stretched. The hairs are clipped off by a sliding knife, R, and by a rotary spiralknife, A. Suitable devices are provided for moving the knives and stretching and feeding the fur.

The operation is as follows: If the cam J raises the rear end of the lever H, the front end will be drawn downward and the connect ing-rod L will be drawn downward. The re sistance offered by the spring N prevents the plate E from being drawn downward, and causes the links M to draw the plates B and the combs A, secured to the same, toward each other until the outer ends of the slots 0 strike against the pins D. The plates B cannot be moved toward each other any farther, as shown in Fig. 2, and the forceexerted by the lever H now overcomes the tension of the spring N and draws the plate E, and with it the plates B and the combs A, downward, as shown in Fig. 3. The edges of the combs A will then hold down the hairs that have been laid down by the current of air issuing through the nozzle NV. As the shaft K completes its revolution the spring J, or another suitable device provided, presses down the rear end of the lever H, whereby the front end will be moved upward and the connecting-rod Lwill be moved upward, and thereby the plates B will be moved from each other until the inner ends strike the pins D, whereby the combs are separated, and then the plate E and the plates B and combs A, held on the same,will be raised, and so on. In place ofcombs, metal strips may be used.

I am aware that combs have heretofore been used on fur-clipping machines, the same being shown in the patent of Gimiotti, granted April 12, 1881, No. 240,007, and my patent granted April 3, 1883, No. 275,077, and I there fore do not claim such invention.

Having thus described my in vention,I claim as new and desire to secure by Letters Patent 1. In a machine for clipping and unhairing fur, the eombination,with a strip over the edge of which the skin is to be passed, of an airforcing apparatus, knives for cutting off hairs of the fur, and of combs or plates for holding down some of the hairs, which combs are arranged to first move toward each other and then downward, essentially as herein shown and described.

2. In a machine for clipping and unhairing fur, the eombination,with a strip over the edge of which the skin is to be passed, of an airforcing apparatus, knives for cutting off hairs of the fur, and of combs or plates attached to upright plates, adapted .to be moved toward each other and then drawn downward, substantially as herein shown and described.

3. In a machine for clipping and unhairing fur, the eombination,with a strip over the edge of which the skin is to be passed, of an airforcing apparatus, knives for cutting off hairs of the fur, combs or plates, upright strips or plates to which the said combs or plates are fastened at the ends, and of means for drawing the said plates to which the combs are fastened toward each other and then downward, substantially as herein shown and described.

4. In a machine for clipping and unhairing fur, the combination, with a strip over the edge of which the skin is to be passed, of an airforcing apparatus, knives for cutting ofl' hairs of the fur, and of combs or plates having their ends securedto upright plates provided with transverse sl ots,through which pins are passed into a vertically-movable plate, and of links connecting the said slotted plates with a connecting-bar having an up-ancbdown movement, substantially as herein shown and described.

5. In a machine for clipping and unhairing fur, the eombination,with astrip over the edge of which the skin is to be passed, of an air forcing apparatus, knives for cutting off hairs of the fur, combs or plates having their ends secured to upright plates provided with transverse slots, through which pins pass into a vertically-movable plate, means for drawing the vertically-movable plate upward, and of links connecting the upright plates with a connectingrod having an up-and-down movement, substantially as herein shown and described.

6. In a machine for clipping and unhairing fur, the eombination,with a strip over the edge of which the skin is to be passed, of an airforcing apparatus, knives for cutting ofi hairs of the fur, combs or plates having their ends secured to upright plates B, provided with transverse slots 0, a vertically-movable plate, E, pins D, passed through the slots 0 into the plate E, the spring N, for drawing the plate E upward, the lever H, connecting-rod L, pivoted to the lower end of the lever H, and the links M, connecting the plates B with the connecting'rod L, substantially as herein shown an d described.
