I MACHINE FOR TREATING HIDES, SKINS, AND LEATHER.

Application filed November 22, 1916.

Massachusetts, have invented an Improvement in Machines for Treating Hides, Skins, and Leather, of which the following descrlption, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to a machine for treating hides, skins and leather, and has for its object to provide a machine with which the major operations now performed upon the hide, skin or leather by a plurality of machines of different constructions, according to the particular-kind of work such as unhairing, fieshing, putting out, setting, shaving, etc., being performed, may be done in a superior manner upon a single machine. To this end, the machine is provided with a bed of substantially small working area to support the work, preferably in the form of a roll of relatively small diameter, an operating tool, such as a bladed cylinder to engage the work while on the bed, and

a device which is movable with relation to 7 said bed and tool to move the h de or skin away from the operator and toward the bed and tool to enable the hide or skin to be worked by the tool, and then to move the treated portion of the hide or skin away from the tool and bed and an untreated portion of the hide or skin toward the said bed and tool, whereby the hide, skin or leather remains under the eye and control of the operator as it is moved toward the bed roll and operating tool, and is effectively and advantageously acted upon by the bladed cylinder or operating tool cooperating with the small or narrow portion of the hide or skin on the small working area of the bed roll, and further is placed and maintained under tension while the hide or skin is being drawn away from the bed roll and operating tool.

The movable device to which the work is secured may and preferably will be made in the form of a drum of relatively large diameter, and it may be preferred to employ a bolster which is attached to the drum and is passed over the bed roll, which latter may and preferably will be mounted concentrically with the drum.

In the machine herein shown provision is Specification of Letters Patent.

Serial No. 132,891.

made for moving the bed roll from an inoption to the working tool and to permit the bed roll to remain in its operative position while the movement of the drum is continued.

These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a front elevation of one form of machine en'ibodying this invention.

Fig. 2, a section on the line 2-2, Fig. 1, looking toward the right.

Figs. 3, land 5, details in section of the drum, bed roll and working tool to illustrate the operation of the machine and,

In the present instance I have shown the invention as embodied in one construction of machine. in which the greater portion of the machine is of known construction and substantially that shown and described in U. S. Patent No. 802,878 dated Oct. 24, 1905,

and known to the trade as a drum machine. The drum machine herein shown comprises essentially a Segmental drum (0 of relatively large diameter and having a stationary clamping jaw 10 with which cooperates a movable clamping aw 12, carried by arms 13 mounted loosely on the shaft 11 of the drum a. The movable clamping jaw 12 is acted upon by a spring 15 to normally hold the said jaw against, a stop 16, see Fig. 2, and thereby allow the jaw 10 to move with the drum in the direction indicated by the arrow 17, Fig. 2, and away from the jaw 12: so as to open the clamp and permit a portion of the hide or skin 18 to be placed within the drum and over the fixed jaw 10.

On the movement of the drum a in the direction indicated by the arrow 19, which may be termed its forward movement, the fixed jaw 10 is moved toward the jaw 12 and the hide or skin is firmly clamped between them. In the machine herein shown, the drum (4 is rotated in a forward direction indicated by the arrow 19, by a straight belt 20, see Fig. 1, which is passed about a pulley 21 on a main or driving shaft 22 and about a pulley 23 normally loose on a counter shaft 24:, and said drum is rotated in the reverse direction, indicated by arrow 17 by a cross belt 25 passed about a pulley 26 on the main shaft 22 and about a pulley 2'7 normally loose on the counter shaft 24. The pulleys 23, 27, are adapted to be rendered fast on the counter shaft 24. by clutchmechv 35 which meshes with a gear 36 on the drum shaft. The main shaft 22 is provided with fast and loose pulleys 37, 38, and with a pulley 39,which latter is connected by belt 40 with a pulley 41 on the shaft 42 of a bladed roll e3, which constitutes one form of operating tool. The bladed roll 43 is journaled in levers 4A pivoted at 4:5 to the frame work of the machine and connected with a foot treadle d6 as by rods or links 47, so that the operator can bring the bladed roll into its operative position by depressing said foot treadle. The machine as thus far described is substantially such as shown in the patent above referred to. In the drum ma chine of the character shown in the patent referred to, the bladed cylinder 43 cooperateswith the drum a to act on the portion of the hide or skin lying on the periphery of the drum, as the latter is rotated in its forward direction, and this machine has the advantage of carrying the hide or skin from the operator, standing in'front of the machine with his foot on the treadle 46, toward and beyond the working cylinder, and leaves the portion of the hide or skin von the outside of the drum under the eye and control of the operator, Who can see the condition of the hide or skin on the drum and can smooth out any plaits or wrinkles therein with his hands, so that, the hide or skin may be presented to the bladed cylinder in its proper condition to avoid cutting or otherwise injuring the hide or skin. So also on the return movement of the drum, the operator can inspect the work done by the bladed cylinder, and if the work has been improperly done in some places, the operator can. cause the drum to again move forward and subject the hide or skin to a second operation without disturbing or changing the hide or skin on the drum. The drum machine presents a substantially large or wide area of surface for the bladed cylinder to work against, and for certain kinds of work it is not as efficient as those machines in which the bladed cylinder cooperates with the hide or skin while the latter is supported by a bed roll of relatively small diameter, as the bed roll presents a substantially small or narrow area for the bladed cylinder to work on, and

enables the blades of said cylinder to get a into the small point of contact or narrow area of the hide or skinresting on the bed roll, and in the operation of unhairing en'- ables the grain side of the hide orskin to be opened up, and the fine or coarse hairs to be removed, and in the operation of fleshing a smaller and cleaner cut is made. So also if small wrinkles should exist in the hide or skin, the bladed cylinder is better able to get to the bottom of the wrinkles.

So also in the rubber'roll machine,'the

hide or skin is drawn over the bed roll by I means of feed rolls of relatively small dithe eye and control of the operator as it is moved toward'the bladed cylinder, and 00- operates with the latter to present a small working area or surface of the hide or skin for the blades to act against. In the present instance the bed roll 50 1s journaled in arms 51 mounted to turn on the drum shaft 14, and said arms are preferably made of such length that the bed roll 50 contacts with and is supported by said drum, which is of advantage as it prevents springing of the substantially long bed roll of relatively small diameter.

Provision is made for positioning the bed roll with'respect to'the drum a, so as not tointerfere with the clamping of the hide or skin to the drum, and further to enable the bed roll. to be moved with the drum into operative relation to the bladed cylinder, and remain in such position, while the drum continues its forward movement;

To this end, the arms 5i which carry the bed roll, are operatively connected with cams 52 located at opposite ends of the drum and herein shown as path cams, which are suitably shaped to effect movement of the bed roll from its inoperative into its operative position; be held in'its operative position, and after the portion of thehide or skin outside of the drum has been acted upon by the bladed cylinder to be returned with the drum to its inoperative position.

Each path cam 52 is represented in Fig. 6 as provided with a circular portion 53 frnm which extend inclined portions 54, 55,

and one of the inclined portions as 54 ef-' fects movement of the bed rollinto its operative position, and when the drum is reversed into it inoperative position, and if the drum has a continuous rotation in one direction, the other inclined portion 55 effects the return movement of the bed roll to its' inoperative position.

In the present instance, the path cam 52 acts on the short arm 56 of a bell crank lever 57 whose long arm 58'has a pin and slot connection with the arm 51 supporting the bed roll at one end, the long arm 58 carrying a pin 59 which is extended into a slot the drum (4 upon which the hide or skin 18 rests, and in the present instance, the bolster 62 has one end fastened to the stationary jaw 10 of the drum and is passed overthe bed roll and has its other end yieldingly secured by springs 63 to the drum.

The cam may be driven from the drum shaft 1 f by a gear 6+1: on the drum shaft, meshing with an intermediate gear 65, which meshes with a gear 66 fast to the path cam The operation of the machine herein shown may be briefly described as follows: Assume the drum and bed roll in their inoperative positions represented in Fig. 3. The operator .at the front of the machine throws one half of the hide or skin 18 into thedrum and then moves the clutch lever 32 to start the drum rotating in the direction of the arrow 19. As the drum is moved toward. the bladed cylinder 13-, the bed roll 50 is moved simultaneously with it toward the bladed cylinder, until the bed roll has been brought into its operative position with relation to said cylinder as represented in Fig. 1. On the movement of the drum toward the bladed cylinder, the fixed jaw 10 picks up the movable jaw' 12 and the hide or skin is firmly clamped or secured to the drum. WVhen the bed roll has been brought into its operative position, the oporator depresses the treadle 46 and brings the bladed cylinder into engagement with the portion of the hide or skin resting on the bed roll, and as the drum continues its forward movement in the direction indicated by the arrow 19, and as represented in Fig. 5. the hide or skin is carried with it away from the bed roll and bladed cylinder and the latter performs its work, which may be unhairing, fieshing, putting out or stretching, scudding, shaving, etc., depending upon the character of the blades or vanes in the working cylinder 13. On the movement of the drum (4 beyond the operative position of the bed roll, the portion of the hide or skin on the bolster or outside of the drum is moved away from the operator toward the bladed cylinder, but remains under his eye and control, so that, he is enabled to smooth out the hide or skin on the bolster and arrange it so that it may be presented to the bladed cylinder in the best possible condition, and if the hide or skin is in such condition that it cannot be properly smoothed out by the operator, he has it in his power to reverse the machine and'replace the hide or skin.

When the clamped end of the hide or skin is drawn away from the bed roll and placed under tension by the drum cooperatmg with the bed roll and working cylinder,

the grain side in the operation of unhalring is opened up fully in the small area of that portion of the hide or skin which is engaged with thenarrow working area of the bed roll, assisted by the tension or pull upon the hide by the drum and clamps, and as a re-' salt the fine or coarse hairs, dirt or other foreign matter are removed by the blades of the working cylinder, which blades act on practically a point of contact with the hide or skin or what may be designated a surface area of narrow width, which is extended lengthwise or axially of the bed roll. If fleshing and shaving are being done, the small clean cut of the rubber roll machine is obtained. If putting out, stretching or like operations are being performed, they are effectively performed as the work is presented to the bladed cylinder under the eye and control of the operator, and the body portion of the hide or skin can be put out, stretched, etc., and the machine can then be returned to its starting position and the hide or skin shifted and clamped in its shifted position so as to present the shanks in proper position to be effectively treated.

It will therefore be seen, that with a machine embodying this invention, the operations of fieshing and nnhairing which are now performed on the rubber roll machine, such for instance as shown and described in U. S. Patent No. 696,588, dated April 1, 1902 can be performed, and that the operation of putting out, stretching, etc, which are now performed on the so-called single table and serial table machines, such for instance as shown in U. S. Patents No. 27%858, dated Mar. 27, 1883, and No. 722888 dated March 17, 1903, can be performed, and the operation of shaving which is now commonly performed on machines of the character shown and described in U. S. Patent No. 618,620, dated Jan. 31, 1899 can be performed on this machine with advantages not possessed by the. individual machines referred to.

For fleshing and unhairing, a machine ditional advantages of having the hide or skin under the eye and control of the operator; the advantage of retaining the gelatin and other valuable substances in the hide or skin; the further advantage of being able to repeat the operations on the return movement of the hide and also repeat the'operations on a second forward movement with out removing the hide or replacing the same in the'machine, and the still further advantage in the operation otunhairing of a greater opening up of the pores of the hide or skin, becauseof the tension on the hide or skin placed upon it by the clamp which is located at a lower level than the bite of the bed roll andworking cylinder.

For putting out, stretching and like operations the advantages of having the hide or skin under the eye and control of the operator are retained, and the additional advantages of the small area of contact of the blades of the cylinder on the hide or skin, and of the treated portion of the hide or skin being maintained under tension between the clamp and the bed roll and working cylinder, are obtained, with the result, that the wrinkles, water, scud, etc., are removed'in a superior manner, while leaving the untreated portion of the hide or skin, which is approaching the bladed cylinder and bed roll, loose and treeto respond to the working out movement of the helical bladed cylinder. 7

Furthermore for putting out, stretching, etc., it has the advantage of the single or serial table putting out machines, in that the hide or skin after passing the operating tool is kept under tension until the whole pertion-oI" the skin being worked has passed the operating tool, and it has the further advantage that the hide or skin can be placed in any position on the drum and retained in this position against any pull of the working tool, and as a result the shank portions of-the hide or skin can be put out, set out, etc., justas well as the body portion, and thereby dispense with the use of separate machines now commonly used for working out the shanks separate from the machines employed for putting out, stretching, setting out, etc., of the body portions. In the present instance, the drum constitutes one form of movable device which carries the hide or skin from one side of a plane through the operating tool to the other side thereof, and while it may be preferred to use the drum for this purpose, it is not desired to limit the invention in this respect. So also it may be preferred to use a bolster which is secured to the drum and passed over the bed roll as herein shown, but it is not desired to limit the invention in this respect.

In the present instance only sufficient the invention parts of the drum machine have been shown-- the same as that shown inthe Patent N 0.-

802878 above referred to. 1
