APPARATUS FOR TREATING HIDES PREPARATORY TO TANNING.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed April 27,1905. Serial No. 257,742.

'To all whom, it may concern.-

Be it known that I, JAMES WILLIAM DECK- ERT, a citizen of the United States, residing at Oakville, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Apparatus for Treating Hides Preparatory to Tanning; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for treating hides, and especially in the provision of mechanism for soaking, liming, baiting, and tawing hides and skins; and it consists in the provision of a partition-tank in which the hides are sus--.

pended and in which a circulation of the treating liquid is produced by the rotary movement of a winged wheel positioned in a passage-way underneath the partition and causing the liquid to circulate over the top of the partition from one compartment into the other.

The invention consists, further, in connection with the foregoing, of means for hoisting the solids which are precipitated from the liquid and in the returning of the liquid to the tank containing the hides.

The invention is illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings Figure 1 is a sectional view through my improved apparatus. Fig. 2 is an enlarged sectional view showing parts of the invention in elevation, and Fig. 3 is a sectional view on line 3 3 of Fig. 1.

Reference now being had to the details of the drawings by letter, A designates a tank which is provided with an exit-opening controlled by the plug A, and said tank has a central partition B with a space intervening between the bottomthereof and the bottom of the tank, through which space the liquid contained within the tank is adapted to circulate. The upper end of said partition is below the top of said tank, aflording a space over the top whereby liquid may flow from one side of the partition to the other. Hooks C are fastened to the flange D,'mounted upon the upper end of the partition B, and also to the hooks D, which are fastened to the projections D on the ends of the tank.

F designates a shaft which is journaled in suitable bearings and has keyed thereto a winged wheel G, the wings of which are adapted to turn in the space below the partition for the purpose of causing a current of the liquid in the tank. A sprocket-wheel G is also fixed to the shaft F, and a sprocketchain H, passing over the wheel G, also passes about a sprocket-wheel G fixed to a shaft G mounted in the hangers G", which may be suspended from the ceiling of a room. A clutch-wheel I (shown clearly in Fig. 3 of the drawings) is splined to the shaft G and has a lever I, which is pivotally mounted at 1 Fig. 1, and engages said clutch I for the purpose of throwing the same longitudinally upon the shaft G in order that the lugs I may engage the holes J in the hub of the pulley J, which is loosely journaled upon the shaft G Motion is imparted to the shaft G through the pulley N, which is keyed to said shaft and to which pulley belted connection I is had with the pulley N upon the shaft N and said shaft N is driven by gear connection with a motor 0.

M designates a conduit which empties into the reservoir M and is adapted to convey the liquids which make exit from the tank A into the reservoir M. Mounted in the hanger Q is a shaft Q, and Q designates a pulley which is keyed to the shaft Q and has belted connection Q with a pump Q. The casing of said pump has a pipe P leading therefrom downinto the reservoir M, the lower end of said pipe being perforated, and an exit-pipe P leads from the pump Q} and empties into the tank L, which is similar in construction to the tank A on a smaller scale and is provided with a partition L and a winged wheel L mounted underneath the partition thereof, and said wheel is driven by sprocket-chain connection L with a sprocket-wheel L*, rotating with the shaft S, which also carries a pulley S, which has a belt S connecting the same with a pulley Q upon the shaft Q.

Mounted in suitable hangers T is a shaft T, having a gear-wheel T on one end thereof and in mesh with a bevel-gear T upon the shaft S. A sprocket T is mounted upon the shaft T, and a sprocket-chain T connects the same with a .sprocket wheel T, which is mounted upon a stub-axle T mounted in suitable bearings. One end T of said stub-axle is forked and has pivotal connection with the stem W of the spiral hoisting-worm W, which is mounted in suitable hearings in the inclined passage-way. (Shown clearly in Fig. 1 of the drawings.) The lower end of said hoisting-worm-extends through the bottom of the tank Maud is adapted to raise the solid particles which may be precipitated from the liquids and deposit the same at the upper exit end of said worm. An exit-pipe Y leads from the tank L to the tank A, and a plug-valve L is provided to fit the entrance to said exitpipe, and valve-regulated pipes X and X lead into the tank L and by which'liuids may be introduced into the tank L.

It will be observed that secured to the lower portion of the partition, which divides the tank into two compartments, are the curved members G having flanged edges underneath which the winged wheel rotates. Said member is provided for the purpose of causing the paddles as they turn to be out of the current of the liquid and, further, to prevent back pressure upon the upper portion of thewheel.

From the foregoing it will be observed that by the provision of an apparatus embodying the features of my invention the hides may be thoroughly treated by the violent agitation of the liquids, which are caused to circulate from one compartment to the other of the tank A, and after drawing off the liquids from the bottom of the tank the precipitated particles are hoisted by the hoistingworm, and the liquid may return to the tank L, where after being thoroughly agitated by the motor-wheel working therein it may be fed back into the tank A.

While I have shown a particular form of apparatus illustrating my invention, it will be .understood that I may vary the details ofthe same, if desired, in various ways without in any way departing from the spirit of the invention.

Having thus fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

1. An apparatus for treating hides comprising a compartment-tank with a space intervening between the partition thereof and the bottom of the tank, the upper end of the partition being below the top of the tank, a winged wheel mounted in suitable bearings underneath said partition, means for driving said wheel whereby a current may be formed with the liquid in the tank, a reservoir with a valve-regulated passage-way leading from said tank thereto, means for returning the liquid from said reservoir to the tank, a wormshaft mounted in suitable bearings with its lower end extending into said reservoir, and means for operating said shaft, as set forth.

2. An apparatus for treating hides comprising a compartment-tank with a space intervening between the partition thereof and the bottom of the tank, the upper end of the partition being below the top of the tank, a winged wheel mounted in suitable bearings underneath said partition, means for driving said wheel whereby a current may be formed with the liquid in the tank, a reservoir with a valve-regulated passage-Way leading from said tank thereto, a pump, a second partitiontank into which the liquid is raised from the reservoir by said pump, a worm-shaft mounted in suitable bearings and extending into the bottom of said reservoir designed to elevate the precipitated matters from said liquid, and means for agitating the liquid in said second tank, as set forth.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

JAMES WILLIAM DEOKERT.
