LEATHER-ROLLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 333,196, dated December 29, 1885.

Application filed October 2, 1885. Serial No. 178,852. (No model.)

To all whom it may concern:

Be it known that l, EBEN E. CHURCH, a citizen of the United States, residing at Beddington, in the county of Washington and State of Maine, have invented a new and usefulImprovementinLeather-RollingMachines; and Ido hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved attachment for machines for rolling soleleather, whereby the machine may be adapted and adjusted to roll leather of different thicknesses,

and is illustrated in the accompanying drawings, in which- Figure I is a side elevation of a leatherrolling machine with my attachment. Fig. 2 is a side View of my attachment. Fig. 3 is a projection of the front end of my attachment.

Similar letters refer to corresponding parts throughout the figures.

My invention is applicable to leather rolling machines of various kinds, but especially to that patented to John Bright by Letters Patent dated May 23, 1876, No. 177,682, and for use upon which it is more especially designed.

The construction and operation of Bright s machine, which may be taken as a type of the class of machines to which my invention is applicable, is thus described.

A represents the frame of the machine, to the base of which is attached the bed-plate B, upon which the leather is placed to be rolled. The face of the bed-plate B is concaved upon the are through which the roller 0 of the vibrating lever D swings. The upper end of the vibrating lever D is pivoted to the lever E near its end. The other end of the lever E is pivoted to the frame A. To the free end of the lever E is attached a rod, F, which passes up through the top beam of the frame A, through a rubber block, G, placed upon said beam, and has a hand-nut, H, screwed upon its upper end.

I J are two short bars, the adjacent ends of which are pivoted to the end of a connectingbar, K. The outer end of the bar I is pivoted to the lever E directly above the end of the vibrating lever D. The outer end of the bar J is pivoted to the top beam of the frame A directly overthe ends of the bar I and the vibrating lever D. The bars I and J act as a toggle-joint to press the roller 0 down upon the leather. The outer end of the bar K is pivoted to the inner end of the short beam L, the outer edge of which is pivoted to the top beam of the frame A. To the inner end of the bar L is pivoted the upper end of the c'onnectingbar M. The bars K L thus act as a togglejoint to apply pressure to the toggle-joint I J. The lower end of the connecting-bar M is pivoted to the end of the short arm of the foot-lever'N, which is pivoted to the sill of the frame A, and the long arm of which projects into such a position that the workman can readily operate it with his foot to apply pressure to the leather. To the Vibrating lever D is pivoted the inner end of the cOnnecting-barO, which passes between pins or other guides attached to the frame A. The outer end of the connecting-bar O is designed to be connected with mechanism for giving a vibratory motion to the lever D. When the workman removes his foot from the lever N, the roller 0 is at once raised from the leatherby the action of the rubber spring G.

My improvement consists in providing a shaft, T, having the arbors T T and the cocentric t. The top beam of the frame A is made both wide and thick, and is recessed on its under side, across its width, to receive said shaft, the arbors of which are journaled in boxes on either end of the recess in the top beam. The forward end of the shaft terminates in a square head, upon which is fitted the pulley w, operated by the cord or belt a a. Upon the bottom of the top beam of the frame A, I attach the hanger a, preferably by a bolt passing through its thin end and upward through the top beam of the frame and an elastic cushion or spring, G, and secured in place by the nut b. The hanger, however, may be hinged to the top beam instead of bolted, and is so placed upon the bottom of the top beam as to be directly underneath the eccentric t, which bears upon it. The outer end of the bar J of the toggle-joint I J is pivoted to the hanger u.

In operation, if a thin side of leather is to be treated, the pulley w is revolved by means of one of the cords a a, and the shaft T turned until the part of the eccentric t projecting G is brought slightly nearer the bed-plate B than when the projecting part of the eccentric is turned upward, which may be done when a thicker side of leather is to be operated upon.

It is apparent that as each portion of the circumference of the eccentric is presented to and bears upon the hanger u a different adjustment of the machine is effected, and thus it is adapted to treat sides of any thickness. As the projecting part of the eccentric is turned up, the hanger it follows it, being brought up by the expansion of the elastic cushion or spring G.

If desired, means may be provided for locking the shaft T at any desired position; but in practice I find this to be unnecessary, the shaft retaining any position to which it is revolved.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. The combination of the recessed top beam of the frame A, shaft T, journaled in boxes at the ends of said recess and provided with the eccentric t, and hanger u, secured to the under side of said top beam, so placed as to be borne upon by said eccentric, and so attached to said top beam as to yield to downward pressure as the eccentric is revolved, and to follow upward as such pressure is removed, substantially as described.

'2. The combination of the shaft T, provided with the eccentric t, and hanger u, so placed as to be borne upon by said eccentric, and so secured 'as to yield to downward pressure as the eccentric is revolved, and to follow upward as such'pressure is removed, substantially as described.

3. The combination of the lever E, rod F. rubber block G, two toggle-joints, I J and K L, connecting-bar M, foot-lever N, vibrating lever D, which carries the operating-roller G, shaft T, having the eccentric t, pulley w, and cord a a, hanger u, bolt 1), and elastic cushion or spring G", substantially as described.
