To all whom it may concern.-

Beit known that I, PAUL R. DEF. Dl-IUMY, a citizen of the Republic of France, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Electrolytically'lreating Raw Hides, of which the following is a specification.

This invention relates to an improved machine for treating raw hides, leather and analogous substances, and consists in certain peculiarities of the construction, novel arrangement, and operation ofthe various parts thereof, as will be vhereinafter more fully set forth and specifically claimed.

The object of my invention is to providea machine for the above named purpose, which` is simple in construction andv reliable and effective in use, and will automatically reverse its movement.

In order to enable others skilled in the art, to which my invention pertains to make and use the same, I Will-now proceed to describe it, referring to the accompanying drawings, in which` f Figure 1, is a View in sideelevation of ,my machine as it appears when ready for opera# tion. Fig. 2, is a plan sectional view thereof.' Fig. 3, is a view in side elevation partly in section showingsome of the rollers or bars of; the treatingv drum removed. Fig. 4, is asimi# lar View of the treating cylinder and rollersk or bars, showing the raw-hides in place and in the act of being treated or acted upon.' Fig. 5, is a plan View of the upper plate of the ,treatingdrum and the cylinder, and Fig. 6 isan enlarged detail sectional view of the lower portion of the sleeve and its fiange.

vSimilar letters refer to like parts through# out the different views of the drawings.

A, represents the main or supporting frame, which rests on a suitable base or door, to which is secured the various parts of the ma-y chinery, andin which the several shafts ory journals have their bearing. To that portion of the supportingframe, which hasv the doorl a, is secured in a horizontal position 'on the upper surface of said floor a plate a', through suitable openings in which are passed and se-- cured a number of standards or upright posts a2, which have secured at their upper ends a4 plate a3, of substantially the same construction and form as the'plate a'. Throughthe cent-er of each of the plates c', and as, is formed an opening, in the former named plate, for the reception and operation of the Asis clearly seen in Figs. l, and 3, of the drawings, the lower portion of the cylinder B, extends through the floor a, and is provided with a horizontal beveled cogged gear D, which engages with beveled pinions d, and d', which pinions are suitably mounted on vthe Operating or main shaft D', which shaft has its bearings in suitable journal boxes d2, on the main or supporting frame, and extends some distance to .one side of the horizontal gear D, and the treating drum and its cylinder. On this extended portion and adjacent to the pinion d', is mounted a gearE, which meshes with the. gear E', mounted on the shaft F, which shaft is located parallel with the driving shaft D', and atl one side thereof in suitable'journal boxes d2, on the main or supporting frame... Near the gear E, and on the shaftD, is another gear E2, which engages with'a pinion or gearF,on theshaft F, as is clearly/seen in Fig. 2, of the drawings. To one side of the gear E2, and near its outerend the` shaft D', is formed or provided with a screw-threaded section D2, with which engages a traveler or nut D3, whichis forined'or .provided with an arm d3, the upper end of which is'secured to a horizontal bar d4, which is adapted to slide `or move horizontally with with a horizontal sliding bar e, on the inner end of which is provided a belt-guide e', and

which bar is retained in a horizontal positionv by means of brackets e2, secured to the supporting frame. Between the gears F', and E', on the shaft F, is mounted three pulleys H, H', and H2, the pulley II', being a loose pulley, and the one H, keyed to or fixed upon the shaft F, while the pulley H2, is rigid with the pinion or gear E', which gear is loosely Journaled on the shaft. The gears E2, and F', and pinion CZ, are keyed to or rigidly iixed on their respective shafts, but the gear E, and pinion d', are loose on the shaft D', but are rlgrdly connected together thus permitting the reverse motion of the machine, as will be presently explained.

As before stated the cylinder B, is provided with a vertical slot B2, for'the reception of the raw-hides, which are secured in said slots by means of suitable set-screws c, which are located in holes or openings in the cylinder at the desired point. These openings c', arc of sufcient size to admit of the insertion of a wrench or other suitable device for tightening the screws, which screws when tightened, are counter-sunk in the cylinder, so as to offer no obstruction to the movements of the sleeve B', which is provided at its lower end with an annular flange B2, which flange extends from the periphery of the cylinder to the inner surface of the rollers or bars C, and af? fords a vertical pressure on the raw-hides. The upper end of the sleeve B', is provided with a hook or ring b4, to which may be secured a rope which may operate `over a pulley when it is desired to raise the sleeve. As the sleeve may not have suficient weight to give the desired amount of vertical pressure, I may place across its top a bar C3, which may be weighted at one end and adjustably secured to a post C, at its other.

As is clearly seen in Figs. 4, and. 5, the in ner surface of the sleeve B', is provided with an insulation M, which extends from its top to its bottom, and that the flange or 4disk B3, thereof, is also provided with an insulator M', around its periphery, which as before stated extends to the inner surface of the rollers C, which rollers are provided with an insulation, both at their upper and lower ends in the sockets within the plates a', and a2, which are located `as before set forth.

To the upper portion of the sleeve B', is connected by means of a suitable binding-post or terminal 'm,awire N, which leads from said l at m3, to prevent the current of electricity passing through the same.

In the event of the inoperation of the current of electricity through the wire N, at the top of the sleeve B', I may connect another wire N2, leading to the same pole of the battey, to the lower part of the cylinder B. In order to prevent the current of electricity from passing from the horizontal gear to the operating mechanism, the teeth or cogs of saine may be made of any suitable non-conducting material.

The operation of my device is simple and as follows: The sleeve B', is raised so as to expose the slot or a portion thereof 1n thecylinder B, and a number of hides are inserted and secured in said slot by means of set-screws c. The power is then applied to the machine by means of the belt f, which passes over the pulley H, and a power-pulley (not shown), and as the pulley II, is rigid on the shaft F,

it will cause the same to revolve, in which `operation the pinion F', meshing with the gear E2, transmits the rotary motion to the shaft D', which being geared to the horizontal cogged-wheel D, by means of the plniond, will impart its motion to the cylinder B, and cause the hides c10 to beiwound thereon, and to be compressed by reason of the rollers G, which as before stated are placed in a `circle around the cylinder, and in order to prevent injury to the hides by reason of friction, are preferably loosely secured in the plates a', anda, and at the same time the sleeve B', by reason of its own gravity or that 'of the vbar C2, when used, will afford vertical pressure 'on the hides. In the movement of the machine described, the traveler or nut D2, will glide forward on the driving shaft by reason of its screw-threaded connection, and will cause the lever which engages with the bars e', ande?,

to assume the position indicated by dotted lines in Fig. 1, when the belt f, will be forced IOC thereby from the pulley H, to the pulley H2,

which being rigid with the pinion E', which pinion is loosely journaled on the shaft F, and engages with the gear E, which is rigid with the pinion CZ', will impart a reverse mo,- tion to the horizontal gear and through it to the cylinder, and at the same tirnethe traveler D3, will be returned to its normal position and through its 4connections with the traveler, the lever will again cause the belt to shift `back to the pulleyh, when theoperation before described may be again repeated.

In the above stated operation 'the current of electricity is turned on andcarried `through the sleeve B', `from which it passes into `"and through the hides, which may havebeen moistened -to make them a better'conductor, 'thence through the rollers C, and over 'the wire N', or the alternative course 'may be taken. The electric current passingithroughthehidesdevelops a gentle heat, `:and assists in thezdisintegration and separation of thefattyfibrin contained iu the hides, and facilitates randacA celerates the penetration of the `component liquor therein,which quickly ren ders the same pliable, elastic, and silky, by reason of the mechanical and electrical action to whichthey have been subjected.

Having thus fully'described my invention,

what I claim as new, and desire to secure by Letters Patent, is
