Application filed March 14., 1912. Serial No. 683,912.
To all whom it may concern:
Be it known that I, FRANCIS WAYLAND, a citizen of the United States, and resident of Salem, in the county of Essex and State'ot Massachusetts, have invented new and useful Improvements in Hide and Leather Working Machines, of which the following is a specification.
This invention relates to a machine for treating skins, hides and leather, and particularly for glazing and at the same time stretching and staking.
The principal objects of the invent on are to provide a machine of novel and mproved construction and operat1 on which will 'glaze skins over their whole exten at one time, at the same time soften the FKlIl and especially the grain surface of the skin, and stretch and stake the skin preparatory to the glazing and deliver it in stretched condition to the action of the glazing devices.
According to the glazing and burnishing methods heretofore generally employed, the skin has been laid upon a table or supporting bed, stretched out as flat as possible by hand, and glazed with a glass. It is necessary to. use a narrow glass and to treat only a narrow area of the skin at each stroke in order to get the best results, and to properly soften and work the grain surface, since if a wide glass is used and a wide area of the skin is treated at one time thereby, the glass tends to lay down and harden the surface. With my invention the skin is subjected to the action of a work roll or glazing roll provided with a plurality of glazing projections, said roll treating the whole extent of the skin at once and yet without the hardening effect of a wide glass, since the glazing projections each engage only a narrow part of the skin at one time, thus properly worle ing and softening the skin. Furthermore, my glazing projections also perform stretching, staking and putting out functions. Mechanism is also provided to stretch the skin preparatory to the glazing and to pass the skin in stretched condition and under tension to the glazing roll, to prevent Wrinkling or pleating of the skin in the glazing operation. Such mechanism will also perform the operations of staking, putting out, unhairing, etc.
In the accompanying drawings, which illustrate one embodiment of the invention,-Figure l is a side or end elevation of a leather working machine embodying my invention; Fig. 2 is a sectional view showing the relation between the rolls and the stretching jaws hereinafter described, parts being broken away Fig. 3 is a fragmentary front view showing a preferred arrangement of the glazing projections of the work roll; Fig. 4 is a fragmentary face view of one of said jaws; and Fig. 5 is a fragmentary face view of the other of said jaws.
Referring to the drawings: A represents the work roll, B the bed roll against which the skin lies and by which it is supported while being acted upon by the Work roll, and C is a pinch or feed roll, the rolls B and C acting together to feed or draw the skin S through the machine.
The work roll A is driven by a pulley A; the pinch roll or feed roll C is independently driven by any suitable power mechanism; and the bed roll B is driven from roll C by gears c and Z) mounted respectively on the shafts carrying rolls G and B. The work roll A. is journaled on the frame F of the machine, and the bed roll B is ournaled on swinging arm E, which is pivoted to the frame at D and constitutes a movable carrier for said bed roll, whereby the rolls A and B may be separated to admit the work, and broughttogcther to engage the work. The roll O is ournaled at its ends in blocks 0 mounted at each end of the frame to slide in ways 0 A spring 0 normally presses each block 0, and the roll C carried thereby, in the direction of the bed roll B.
The surface of the work roll A is provided with glazing projections which may be of any form and of any material adapted to glaze or burnish the skin. These glazing projections preferably comprise two diverging sets of helical ribs or vanes a, made of glass, hardened wood fiber composition, or other suitable material. They have smooth working surfaces and by reason of their diverging or helical arrangement not only glaze and burnish the skin, but also perform stretching, putting out and staking functions. In addition to the ribs 0., other glazing projections may be provided such as the smooth rounded knobs a of similar eration.
material arranged between the ribs a. Or such knob-like projections could be used without the ribs. Roll A is covered with an elastic cushion a of felt or other suitable springy material, and the glazing projections are secured to and bear on this cushion so that said projections will yield inwardly and provide yielding pressure of the glaz ing projections upon the work lying against the bed roll B, when the machine is in op- The ribs a are secured to the cushion a by angle clamps a Below and close to the rolls A and B are a pair of stretching jaws G and H of substantially the same length as said rolls. One of said jaws, the jaw H as herein shown, is rigidly mounted on the swinging arm E, and the'other, the jaw G, is pivotally mounted on said frame at I. Each of said jaws is provided with two diverging sets of vanes or blades, one set inclined to the right and the other 'to "the left, the blades of one jaw intermeshing with those of the other when the jaws are closed in operative position, that is, the blades of one jaw projecting into the channels between the blades of the other, as shown in lfigs. l and 2. The blades of jaw G are shown at g and those of jaw H are shown at h. The blades of one or the other of said jaws, and as herein shown the blades 9 of aw G, are comparatively thin and are flexible and resilient, to provide for inequalities in 'the thickness of the skin, so that the latter will be treated uniformly throughout its Whole surface, while the blades h of the other jaw are rigid and inflexible. One of said jaws also has two longitudinally extending scraper bars it, h, one at each side of said blades, to press and scrape part of the moisture or water out of the skin as it passes between the jaws, and the other jaw has a pair of opposed pads of felt, or other suitable material, with which said scraper bars cooperate to press and scrape the skin. Said bars It also serve as tension bars, the lower bar it putting tension on the skin for the action of blades g, and both bars serving to put tension on the skin for the action of the glazing roll. The pressure upon the skin between the sides of said blades may be varied by means of the Jpedal P, actingthrough connecting rod and pressed down by the foot of the user to increase the pressure between said blades, and lifted by spring K to relieve said pressure,
The operation of the machine is as follows: The arms E, carrying the bed roll B and jaw H, are swung away from work roll A and feed roll C, thiis opening the parts which coact upon the skin, to admit of the insertion of the skin. The mechanism for swinging the arms E back and forth may be of any well known construction and mode of operation employed in other leather working machines, and need not here be described. The skin S is then placed be tween the jaws (z' and H, the roll A and bed roll B, and the rolls C and B, and the arms E swung to closed position, said jaws and rolls engaging the skin as shown in Fig. 2. Thereupon, the rolls being rotated in the directions shown by the several arrows,
rolls C and B will feed or draw the skin upward and outward from the machine, and the glazing projections on roll A will glaze and burnish the surface of the skin lying against bed roll B. By reason of the diverging helical form of the projections a,
roll A will also perform spreading, stretching, staking and putting out functions. The jaws G and H, by their diverging blades or vanes, and bars, stretch the skin laterally preparatory to passing it to the work roll;
perform staking and putting out operations; press and scrape off part of the water from the skin which comes wet from the previous steps in its treatment; deliver the skin in stretched and fiat condition to the projections made of a form and material adapted to glaze or burnish a skin, a pair of stretching jaws one at least of said jaws having two diverging sets of blades cooperating with the other jaw to engage and stretch the skin laterally before. it passes to said roll, and means to vary the pressure between said jaws.
