FLESHING MACHINE.

Applicationflled April 14., 1923. SeriaLNo. 632,071.

To all whom it may concern:

Be it known that I, ALBERTUs TRAvIs, a

citizen of the United States, residing at provide corrugated and rubber rolls mounted in a new and novel manner for directing the hides to the knife cylinder.

A further object is to mount the knife cylinder adjustably so that it can be minutely shifted toward or from the hide being treated.

A still further object is to provide yielding means for actuating the said rolls relative to the knife cylinder so as to adapt them to hides of different thicknesses.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combination of parts whichwill be hereinafter more fully described and pointed out in the claim, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit of the invention as claimed. In the accompanying drawings the preferred form of the invention has been shown- In said drawings:

' Figure 1 is a plan view.

Figure 2 is a front elevation.

Figure 3 is a side elevation.

.Figure 4: is an elevation with the drive mechanism removed, the feed roll being shown in active position relative to the fleshing or knife cylinder, the parts of the machine being removed on the lines-4: Figure 1.

Figure 5 is a section on line 55 Figure 1.

Figure 6 is a section on line ure 4:.

Figure 7 is a section on line 77 Figure 6.

Figure 8 is a section on line 8-8 Figure 1.

Figure 9"is a section on line 9-9 Figure 8. I

Referring to the figures by characters of reference 1 designates the side frames or standards of the supporting structure, these being pivotally connected as by means of a rod 2 and a rear beam 3. Each frame has an upwardly extending portion 4 near the front thereof formed with a slot 5 and in the top of this portion 1 is provided a bearing 6 in which is journaled the shaft 7 of a corrugated main feed roll 8.

Studs 9. are extended laterally from the standards 1 and mounted to swing'thereon are arms 10 each of which has a pair of bearings 11 and 12 at its upper end. Journaled in the bearing 11 is the shaft 13 of a rubber pressure roll 14; while the shaft 15 of a supplemental corrugated feed roll 16 is journaled in the bearings 12. See Fig ure 1. The shafts 13 and 15 extend through and are adapted to swing within the slots 5, the rolls. 14 and 16 being interposed between the extensions 4.

Shaft 7 is provided near one end with a gear 17 and a gear 18 is also provided on one end portion of shaft 13. This gear is designed to swing into and out of mesh with 7 gear 17 when the arms 10 are swung back and forth respectively.

Another gear 19 is secured to shaft 7 near its other end and is adapted to be engaged by a gear 20 secured to one end of shaft 15. Thus when the rolls 14 and '16 are swung toward the roll 8 gear 20 will be.

brought into mesh with gear 19 While gear 1 18 will be brought into mesh with gear 17.

The shaft 21 is journaled in the rearportion of the standards 1 and secured to this shaft close to the outer side of each standard is an eccentric 22 engaged by a split strap 23 from which extends an arm 24.

A longitudinal slot 25 is formed in the arm and slidably mounted in the arm is a rod 26 pivotally connected at 27 to the adj acent swing arm 10. A coiled spring 28 is mounted on each rod 26 within slot 25 and bears at one end against one wall of the slot and at its other end against a nut 29 adjustably mounted on the rod. Thus the springs on the two rods serve to hold the arms 10 normally swung toward arms 24. This swinging movement can be limited by stop nuts 30 adjustably mounted on the rods 26. andadapted to bear against arms as. I

- 9. Arm 38 is connected to a rock shaft 39 extending from the rear to the front of one of the standards l and provided at its front end with a foot pedal yieldingly supported by a spring 41 suspended from a bracket 42. "A disk43 is carriedby and rotates on the sha'ft21 and has a recess 44 in one facethe "peripheral wall of which is formed with an annular-series of teeth'45. A collar46 rotates with'shaft 21 and is seated in recess 44, this collar being provided with adog 47 pivotally connected thereto as at 48 and normally pressed outwardly by a spring 49 carried by the collar. Tripping studs50 are extended from the respective end portions of the cross head 33and are adapted to project into recess 44 so as to be engaged successively by the dog during the rotation of the collar 46and shaft 21. A large pulley 51 and a small pulley 52 are connected to and ro-' tate with disk 43, the disk and pulleys being normally mounted for'free rotation on shaft 21.1 [Under normal conditions the dog 47 is pressed against one'of the studs 50 so that disk 43 can rotate freely on theshaft 21.

;By.,depressing foot pedal 40' arm 38' will swing and cause thecross head 33 to slide on shaft 21,. thereby withdrawing studs 50 from the path of dog 47 Consequently spring 49 will throw the dog into engagement with one :50 will be stopped. This rotation of the shaft will besufiicient to cause the eccentrics 22 to pull rods 26 longitudinally, thereby to swing arms 10 toward shaft7 and roll 8. The skin "ithis gripping operation.

pedal 1s next depressed so as to again re or hide to be fleshed is first placed over the rolls 14 and 16 and obviously this movement of the arms 10 will cause the hide to'be gripped between the rolls 8 and 16while, at the same time, gear 20 will be brought into mesh with gear 19 and brought into mesh will gear17; Should the hide'be of uneventhickness one or the other of the springs 28 will be free to yield during lease dog 47 the shaft 21 will make another one-half revolution which will'be sufiioient in Figure 1. we rdly from'the'standards 1 and journaled gear 18 willrbe When the foot to swing the arms 10 back to the position shown in Figure 3. a

Each of the standards 1 has a bearing 53 slidably mounted thereon and journaled in these bear-ingsis the shaft 54 of a fieshing cylinder '55 on which are provided knives 56 preferably curved as illustrated for example Arms 57 are extended uptherein is an. adjusting screw 58 parallel with shaft 54 and having oppositely threaded portions 59 and 60 engaging oppositely pitched wedging blocks 61. These blocks are slidable transversely of the standards ;1 infront of the respective bearings 53. It

will be obvious, therefore, that by rotating screw 58 in one direction the-wedges 61.,will be drawn toward each other, thus "to force the bearings 53 toward slots 5. By rotating the/screw in the opposite direction. the

wedges will be moved apart andfthe shaft 5 4 is thus free to slide or shift backwardly away from the slots 5. Each of the standards is preferably formed with'anupstanding abutment 62 for one of the wedge blocks 61. A hand wheel 63 or the like can be secured toone end of the screwto facilitate the rotation thereof.

Shaft 54 constitutes the drive shaft of the machine and has a pulley 64 at oneend'for engagement by a drive pulley. A pulley 65 is carried by the other end of the shaft and is adapted to transmit motion through abelt 66 to a pulley 67 mounted for rotation on a stud 68 projectinglaterally from one of the standards 1. A gear 69 rotates with pulley 67 andmeshes with a gear 70 carried by a stud 71 projecting from said standard 1. .A

pulley 72 rotates with gear 7 O and is adapted to transmit motion through a belt'73 to the pulley 51. Another belt 74 is used for. transmitting motionfrom the icy 75 secured to the shaft 7. i

In using the machine shaft 54 is rotating constantly and, consequently," motion is being transmitted constantly through the belts and pulleys and through the gears69 and7O to the shaft 7 and pulley 51" as well as disk 43.

The operator places the hide "or skin'on the rolls 14. and 16. Foot pedal 40 is depressed momentarily so as to cause the arms 10 to swing rearwardly and grip the hide between the rolls 16 and 8. At the same time the gears 20 and 18 will be brought into mesh with the gears 19 and l7 respectively so that while roll 8 is rotating in a elookwisedirection when viewed as'in Figure 3, the other rolls 14 and 16 will be rotated in a counterclockwise direction. The two rolls 8 and 16 pulley 52 to a pul- 1.100 upward direction and when the entire surface has been treated the foot pedal 40 can be depressed momentarily as heretofore explained so as to cause the arms 10 and the rolls carried thereby to swing forwardly to their initial positions. By means of the adjustment provided for the bearings 53 and illustrated in Figures 6 and 7 the fleshing cylinder can be shifted minutely toward the hide so as properly to engage the same.

What is claimed is:

In a fleshing machine the combination With a supporting structure, a feed roll, a

fleshing cylinder, and means cooperating with the feed roll for directing a hide to the fieshing cylinder, of slidable bearings supporting the flashing cylinder, and means for simultaneously shifting the hearings to adjust the fieshing cylinder relative to the feed roll, said means including opposed Wedge blocks engaging the respective bearings and an adjusting screw having oppositely fixed threads engaging the respective blocks.

In testimony that I claim the foregoingas my own, I have hereto aflixed my signature in the presence of two witnesses.
