MACHINE FOR TREATING HIDES OR SKINS.

Specification of Letters Patent.

Application filed February 12, 1910.

Patented June 21, 1910.

Serial No. 543,560.

To all whom it may concern:

Be it known that I, WILLIAM EVANS, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Treating Hides or Skins, of which the following is a specification.

My invention relates to certain improvements in a machine for fleshing or slating hides or skins by the use interchangeably of a knife or iieshing cylinder or of a slating cylinder in conjunction with an endless adjustable conveyer-apron when provided with a grip-roller for holding or positioning the hide or skin while acted upon in its travel, corresponding in diameter to that of the drive-roller for said conveyer-apron, and which rollers are positively geared together, to revolve at the same speed and thus to insure better control of the feed and correspondingly improved fleshing or slating action upon the skin or hide and also economy in wear throughout of the grip-roller in practical use in such type of machines; and my invention further relates to the constructive arrangement of the grip-roller for such a type of machine, which in diameter corresponds to that of the drive-roller, for an endless conveyer-apron, the said griproller having certain surface formations, as helical grooves broken by circular grooves in spaced relationship, arranged transversely to the helical grooves, whereby is provided a means due to such arrangement, for the uniform and even holding of the hide or skin in its travel through the machine.

My invention consists rst, in a machine for treating hides or skins having a griproller in diameter corresponding to the drive-roller for an endless adjustable conveyor-apron arranged to be manually shifted into the path of a rotating fleshing or slating cylinder; and second, a grip-roller of the character dened.

The nature, characteristic features and scope of my present invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, in which- Figure 1, is a vertical central sectional view through a machine forl treating hides or skins, embodying particularly main features of my said invention. Fig. 2, is a. front elevational view in broken section of so much of a machine as serves to illustrate my said invention, in operative relationship, for the performance of the actions upon a hide or skin, as hereinbefore defined, and also showing the grip-roller provided with helical grooves, broken by circular grooves in spaced relationship and arranged transversely to the helical grooves thereof; and Fi 3, is a vertical sectional view of the said grip-roller on the line w, of Fig. 2.

Referring to the drawings, 4 is a side standard of the machine.

5 is a mechanism for operating a treadle 6.

7 is a feed table adjustably connected with standards 4.

8 is an endless conveyer-apron mounted on rollers 9, 10, 11, as shown, in an operative position. The roller 9 is the drive-roller.

10 is the shiftable roller actuated by means of the treadle-mechanism within the standards 4, and 11 is the stationary guideroller of the conveyer-apron 8.

12 is either a rotary leshing or slating cylinder, journaled in the standards 4, and operated in any well understood manner. A familiar example, of a type of fleshing or knife cylinder that may be used is shown and described in United States Letters Patent granted to me, under date of September 25th, 1894, No. 526,387.

13, is the grip-roller journaled in the standards 4, and on a journal 16 thereof is mounted a gear 14, arranged to mesh with a complemental gear 15, on a journal 17, of the apron drive-roller 9. Both of said gears being arranged beyond one of the standards 4. The journal 16, carries a large gear-wheel 18, which meshes with a smaller gear 19, and both operative from the main driving shaft 20. This shaft carries loose and fast pulleys 21 and 22, as clearly illustrated in Fig. 2. The drive-roller 9, and grip-roller 13, are each of the same diameter and geared to each other so that they do travel at the same-rate of speed and thereby to uniformly or evenly hold the hide or skin in its travel through the machine, when the apron 8, is brought into an operative position, as shown in Fig. 1; and also to economize in wear of the griproller 13, and thus to insure better leshing or slating action of the hide or skin, owing to the unison action as to speed of the said grip-roller 13, with respect to that of the drive-roller 9, of the apron 8, carrying the hide or Skin thi-@agb the machine, aided particularly by the particular surface formations of the grip-roller 13, as clearly shownin Figs. 2 and 3. The surface formations consist of helical grooves broken by circular tions are `given to the ghide or skin the flesh-ing o-rsslating thereof. ,The defined :arrangement 'rof roller 13, -enables particularly economical :results being obtained, .because ofthe uniform Wear ofthe parts of the -machine,due tto the unison of speed as arranged, fof the said 4Working parts ofthe machine.I .1 f

Havingthusdescribed-fthe nature and Vobjects ofmy linventiomavhat I claim as .new and :desire to :secure by Letters Patent is 1. In a machine :provided Witha conveyerapron and-driveerollen la `grip-roller =in diameter corresponding dio .that of said driveroller, and said grip-roller provided With certain grooved formations broken by certain grooved formations in spaced relationship, oppositely arranged in respect to each other, to insure thereby, more smooth or even surface conditions being given to the hide or skin, substantially as described.

'2. In :a `.machine provided with a conveyerapron and drive-roller, a grip-roller in diameter corresponding to that of said driveroller, and said ygrip-roller 2provided with helical grooves broken by-circular grooves in spaced irelationship, arranged` transversely to :said helical grooves, substantially as and for the purposes described.

In Witness whereof, I have hereunto set my rsignature in the presence of two subscribing Witnesses.
