IMPROVEMENT lN LEATHER-DRESSING MACHINES.

Specification forming part of Letters Patent No. 173,627, dated February 15, 1876; application filed November 6, 1875.

To all whom it may concern g Be it known that I, JOSEPH HEAD, of Andover, inthe county of Alleganyand State of New York, have invented a new and valuable Improvement in Leather-Dressing Machine; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked- "thereon. 7

Figure l of the drawings is a representation of a longitudinal vertical section of my leatherglassing machine. Fig. 2 is across-section of the same. Figs. 3 and 4. are detailed views.

This invention has relation to machinery which is designed for glassing or dressing and finishing leather; and the nature of my invention consists in a novel construction of apparatus for-regulating the pressure of the dressing-tools upon the'leather, which is fastened upon the table beneath, as will be hereinafter explained.

In the annexed drawings, A designates a table, on which the leather to be dressed is applied, which table is mounted'upon caster wheels B, that allow it to be turned around in any direction in a horizontal plane. Above pitman-rod, E, the other end of which rod is applied on a wrist-pin, 2, fixed eccentrically into the wheel F, on a driving-shaft, F. E is a rod, which is pivoted at one end to the pitman-rod E, and at the other end to a cross-bar,

(1, connecting together the two plates D D. The pivot-pin which connects the rod E to the pitman-rod E,.is free to play in an oblong hole made through an car on said pitman-rod. By

turning the shaft F, the plates D will be caused to oscillate about the shaft 0, and they will be moved back and'forth with the slides b b. v

G designates a frame which is vertically movable, and which is composed of two'slotted side plates, 3 3, a top connecting-plate, 4, and

twobracket-guides, e e, which latter are constructed with lips that embrace the edges of the cheek-plates D D. r

H H designate clamping-jaws, which are designed for holding the slickers, and which are rigidly secured to arms j, that are pivoted to a cross-bar, g, of frame G. From these jaws H H rise arms h h, which are slotted, and which have books a adjustably secured to them by means of nuts j. To the hooks a, and also to hooks 70, on the brackets e e, helical springs s are attached, which hold the slicking-tools down to their work, but allow them to yield while passing over inequalities. By

adjusting the hooks i the springsscan be made to exercise more or less force in holding the slickers down upon the leather on the table.

The frame G is vertically movable, and is held up by means of springs S. On top of this frame G is a frictionroller, Z, and above this roller is a horizontal beam, J, which is connected to the short arms of levers J J by means of linksm m. The levers J have their fulcra in the hangers 'n n, and their longest arms are connected to a hand-lever, L, by means-0f rods 0 o. The beam J is raised, when the lever L is released, by means of a spring, S. By depressing the beam J it forces the frame G down, and causes the slickers to press hard upon the leather. The frame may be held down, even after the beam J is-freed from it, by means of a notched arm, N, and

spring-catches p p, which latter are opened to release frame G by means of a cam on the stem of a hand-lever, r. 7 What I claim as new, and desire to secure by Letters Patent, is-- l. In a leather-dressing machine the slickers H H, applied in a vertically-movable frame G, in combination with therectilinear reciprocating and oscillating frame D, and springs S, substantially as described.

2. The pressure-beam J, its levers J and lever L, combined with the ertically-movable In testimony that I claim the above, I have frame G, carrying slickers, and operating as hereunto subscribed my name in the presence described. I of two Witnesses.

3. In combination with the frames 1) G operating as described, the notched arm N, Witnesses: springcatches p p, and the lever r, substan- H; W. SANFORD, tially as described. 0. B. SPAULDING.
