AUTOMATIC HIDE-TANNING MACHINE,

Specification of Letters Patent.

Patented May 18, 1909.

Application led October 2, 1905. Serial No. 281,003.

To all whom it may concern:

Be it known that 1, CHARLES JOHN G-LAsEL, a citizen of the United States, residing at South Boston, Massachusetts, have invented new and useful Improvements in Automatic Hide-Tanning Machines, of which the following is a specification.

My invention relates to automatic hide and leather treating machines and has for its object the novel construction and management of its parts whereby the skins or hides to be treated are manipulated, worked and carried by rigid connections with the receptacle in combination with moving connections which are adapted to move in radial, longitudinal or various directions and be contained within said receptacle but moving independently of it. These and other details and objecps of my invention are more fully described in the following specification and set forth in the appended claims.

ln the drawings forming part of this speciiication and accompanying same, like reference characters are used to designate the same parts in the various views.

Figure 1 is an elevation of a tanning machine embodying my invention. Fig. 2 is a longitudinal sectional view. Fig. 3 is a cross sectional view on the line 3 3 of Fig. A2. Fig. 4 is a cross sectional view on the line Ll-Ll of Fig. 2. Fig. 5 is a fragmentary sectional detail showing a modified form of a frame. Fig. 6 is a longitudinal sectional view of the machine showing a means of mounting the skins without using frames. Fig. 7 is an end view of this form of machine, Fig. 8 is a fragmentary elevation of one of the end frames. Fig. 9 is a similar view of the intermediate frame. Fig. 10 is a view illustrating the reciprocating means for the supporting roller. Fig. 1.1 is a view of a modiiicd form of supporting roller.

ln view of the well known construction and operation of these tannery receptacles, I have not illustrated all the details of the cylinder 5 of the various figures but have shown only enough to clearly illustrate my invention.

The cylinder 5 may be of any desired construction and size, and is provided with heads 6 and 6a and circumferential rails or hoops 7,

the latter running in the grooves of supporting and propelling rollers 8 and 9 on shafts 10. These shafts are journaled in standards 11 of the construction shown in Fig. 1 Where it will be seen that there is some space existing between the upright supports of each standard which allows ample room for a longitudinal movement of each roller along its shaft, the shaft at roller 9 being double threaded to allow of a reverse movement of the roller when it reaches the limit of its confines and starts back in a reverse direction. The roller 9 is provided With its necessary interior stud 9a which plays in the reversing thread and the roller 8 is slotted at its hub to play on a spline on the shaft and freely move longitudinally while rotating with said shaft. The roller 9 is causedby the screw threads to move forward and reverse with a reciprocatory motion, and the cylinder 5v is thus caused to reciprocate through the connection between the rails 7 and grooved wheels; the rollers 8 and 9 at the same time imparting a rotary movement 'to the cylinder. The shaft 10 and its rollers are rotated by means of the pulley 12. Thus the cylinder 5 is bodily rotated and also longitudinally reciprocated., the reciprocal movement being as great as the distance between the arms of standards 11. The reciprocal movement of the cylinder causes a continuous agitation of the tanning agent therein, and increases the efficiency of the action of the agent in the process of tanning by repeatedly bringing the agent into contact with the hide with a splashing or washing effect against the hide.

In Fig. 2 it will be seen that the heads 6 and 6JL are each on their interior provided with rings 13 having interior 'eccentric grooves 14 and within these rings are fitted coinciding disks 15 carrying a uniting shaft 16 at a point eccentric with their centers but identical with relation to the axis of the cylinder. On the periphery of each disk is a stud with roller 17 which runs in the groove 14 of the adjacent ring and carries the disk up and down the rings interior, working in unison by means of the connecting shaft 16. With relation to the shaft 16, the disks 15 are eccentrics and the shaft is of suflicient soliditl and weight to retain same below the aXis of the cylinder when it is revolved. Upon the shaft 16 are loosely mounted frames 18 and 18a of wheel-like construction, the end frames 18 being held against longitudinal movement by the collars 19 .while the intermediate frame 18L is freeto rotate and slide on the shaft. The construction of the frames 18 is shown in Fig. 3, where it will'beseenthat a ring or tire 20 is provided with a plurality of sockets 2.1 to vreceive the spokes v22 vwhose inner ends are carried by.a hub 23, the inner side of each ring having hooks 24 or similar attaching means to secure parts of the hides and hooks 25 on fthe hubs serve the same purpose at that point. The intermediate frame .181L is vcomposed of a ring 26 and [the ring is attached to the interior of the cylinder by means of toggle arms 30 of thin resilient material yet sufficiently substantial to afford means to cause'the yframe 18a-to 'follow the cylinder in its rotation but yieldto any 1lateral strain put upon it from either side. This frame has hooks orclamps 31 on each side adjacent to the frames 18 and to the hooks ofthe threeiframes hides are hung as shown in Fig. 2 and as the cylinder 5 revolves and, lthrough the medium of the grooves '14 and rollers 17, reciprocates ythe shaft 16 andthe frames 18 yfirst toward one endand then the other, thehides being held practically stationary by one end at the -intermediate frame are stretched and allowed to `relax alternately by 'the reciprocating frames. With ythe arrangement of hooks around the rings a considerable number of hides may be placed in-position and treated. When'the treatment has been concludedthe 4ring `18aiis disconnected from the cylinder 'by removing the ytoggle arms 30, access being lhad to ythem bythe manholes 82, and by removing the head 6 and releasing the grooved ring 13 "from the head 6u7 Vthe shaft, its frames and the hides may be taken out and ,a new supply furnished. In the treatment of the hides'the cylinder is partly filled with certain'liquors, air, gases, etc., well'known to Ythe art and as the device is actuated, the

hides are Vimmersed and carried from the liquid, the stretching and relaxing operation continually going on to cause 4the ypores of the skin to absorb the solution which -peneyexpels vthe used solution andleaves'thepores ready for a new or fresh supply.

:In lFig. 5 is shown a modified arrangement of one of the frames, preferably the interforth in the following claims.

mediate frame; wherein the eccentric 83 is mounted fast on the shaft 16 and V'has its roller84 playin rthe grooveofthe .hub 35 of the frame 36. The shaft is in the case stationary and the frame connected by any suitable means with Y.the .interior of the cylinder so that when the latter' is operated the frame is rcarried `in and out of the solution which is thus kept agitated, and the hides are immersed and subjected to the `stretching action while secured to this frame and one or more adjacent frames.

In Figs. 6 and 7 is shown a means by which the hides are stretched and relaxed on llines radial and parallel with'the axis ofthe device while being jimmersed and removed from the solution. In'this means of accomplishing this end l employfthe usual eccen trics 38 in the cam-groovedrings 39 and l:having the studs 40 to act inthe groove=to shift lthe eccentrics longitudinally. The eccen- Atrics are provided with shafts or Atrurmions 4'1 one of which is provided with apulley 141iL to rotate same and receives Vmotion `from a similarI pulley on the roller shaft 10. 'They are also united by a shaft 42 on aline intersecting the axis of the cylinder and provided Vwith several loose sleeves 48 which carry )oints7 4hooks or clamps 44 to Asecure the lhides -whose other ends are attached ltothe interior of the cylinder byhooks similar to 44. This arrangement provides yfor the -radial action on the hides to amore or VAless degree as 'the center of the cylinder 'is 'receded from and provides for the treatment of 'hides of different sizes andquality. The hides are'in this case subjected to stretching and contracting manipulations on various angular lines between vthe point a and l'the points?) and c,infFi g. 6 as the reccentrics"3 -8 Vare shifted to lthe'left hand end o'ffthecylinder and as the shaft 42 moves around-and upward at the same end of the cylinder, 'the strain between the points a andb,and c and d, increases and the reverse movement of 11,0 vthe parts produce relaxation 4in the hide l:between these points, and as the eccentrics 88 4reverse their movement the strain is from `the `point d.

4In Fig. 11 is shown an eccentric support- 115 ing roller 46 whichmay be utiliZedto-produce a vertical ymovement ofthe cylinder when used in pairs on each side of thevapparatus, or when'used on one shaft only may produce a movement about the shaft withordinary 120 rollers. With themanagement offthe'frames as shown in Figs. 3 and 4, a clear and open space isleft in the upperpart of this cylinder which affords abundant room for the accommodation of thehides.
