Letters Patent Np. 114,620, dated May 9, 1871.

IMPROVEMENT IN SHANK-MARKING TOOLS.

The Schedule referredto in these Letters Patent and making part of the same.

I, SAMUEL STONE, of Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in Shank-Marking Tools, of which ihe following is a specification.

Nature and Object of the Invention.

painting or staining, 850., of the shank of the boot or shoe at the point where it meets the sole proper.

Description of the Drawing.

Figure 1 is a view from the side. Figure 2 is a viewfrom the top.

Description of the Invention.

In the drawing-- A, figs. 1 and 2, is a last, supposed to be covered with a boot or shoe.

The last is held in position by ahead-block, so called, a contrivance well known in the boot-manufacturing trade, which, therefore, needs no further description than to say that it consists of a flat disk, B, (with a hole in the center,) which lies horizontally and bears at the right-hand side two perpendicular ears, 0, fig. 1, which carry the head piece.

D, fig. 1, an upright block of metal turning upon a pin, E, fig. 1, passing through it and the ears, which block carries above a small perpendicular shaft, D,

dotted lines, fig.- 1, and projecting from its lower end on the back side a horizontal arm, F, called the spindie-arm, used for holding the head-piece D and its last (and boot) in place.

G, fig. 1, is a curved piece of metal hollowed on its upper surface, called the toe-support, joined to and rising from the flat disk B, which piece G supports, as seen inthe drawing, the toe end of the last A.

It has not been thought necessary to include the whole of the head-block in the drawing.

. I now come to my special device.

Proceeding horizontally to the lcft'is an arm, H, fig. 1, (aflat bar of iron,) fastened by the screw-bolt and nut Hf to the projection from the disk B at the left of the toe-support G. This arm, called the bearerarm, carries a collar, I, called the arm-collar, which is a ring, whose axis is perpendicular. This ring or armcollar I has a set-screw, J, called the standard screw, by which it is held firmly.

K K",'fig. 1, are washers above and below the armcollar I, which, their appropriate set-screws, seen in fig. 1, being tightened, held from slipping up and down the standard.

L, a solid shaft, which proceeds I perpendicularly through the arm-collar I to a height a little above the last'nnd boot, shown in the drawing.

At this elevation it bears at-its end ariug, M, called the axle-shaft ring, whose bore is horizontal. Through this bore passes, loose enough to permit its turning, a round shaft, N called the axle-shaft, which passes at each end through a long slot in each of two parallel bars or strips of metal, U .U, fig. 2, (U, fig. 1,) called the frame-bearers.

The respective ends of'the axle-shaft bear each, outside of the respective slots through which they pass, a washer and a nut, seen in fig. 2, which nuts, when screwed up, hold the'frame-bearers to the axleshaft.

The ends of the flame-bearers nearest the last and boot are fastened to the sides near the bottom of a light frame of two small slabs of wood, P P, fig. 2, (P, fig. 1,) called the frame side pieces, connected at the top by a similar slab, Q, called the top piece, which latter, in top View, is seen to be slightly curved. At a short distance from the lower ends these side pieces are connected by another slab of wood, R, fig. 2, called the bpttom piece, the front of which is cut away in a semicircular form.

S is a thin piece of steel, called the marking-plate, passing across the bottom of the frame and fastened firmly thereto by two screws, (see fig. 1,) which are provided with nuts, so as to admit of removal or changing of the marking-plate at pleasure.

Between the marking-plate and the bottom of the frame are placed at each side, respectively, two pieces of rubber, T, called the plate-springs. (See fig. 1.)

The marking-plate is seen in the drawing to be cut away in front in a semicircular form, sometimes in shape of'the top of a heart, or in-other shape.

And the operation of mydevice is as follows:

The last with a boot or shoe over it being placed on the head-piece D in the position seen in the drawing, the frame with its marking-plate isslid backward or forward on the axle-shaft, according to the size of the boot to be 'marked, till the marking-plate is at the point where it is desired to mark the shank. The nuts on the axle-shaft are then tightened. The frame'is then turned to the right or left (the standard L being capable of rotation in its bearing) according as the boot or shoe'to be operated on isa right boot or a. left boot. The standard-screw J is then tightened, thus holding the frame as it may have been set. Should it, according to the size of the'boot or shoe, be necessary to raise or lower the frame, the standard-screw being loose, the washers K KT are also loosened, and the standard is forced 'downor pulled up throughthe arm-collar I till the frame is at the proper height, when the two screws K K are tightened. lhe marking of theshankmy last and boot and my frame and its attachments in other convenient modes, and sometimes-I have my frame-bearers cylindrical, and have two rings carrying set-screws, one at each .end of the axle shaft, all insteadlof the slot and nut and screw arrangement; and I sometimes use a wedge instead of my set-screw J to hold the standard L in place.

' What Iolaim herein as of my own invention, and

desire to secure by Lettexs Patent, is-- 1. The combination and arrangement of the markin g-plate S and its frame P P Q with the frame-bearers U U, axle-shaft N, and standard L, whether the same be used with or without the head-block, all substantially as described.

' 2min combination with the standard L, the frame-- bearersU U, the axle-shaft N; the frame P: P Q,Vand marking-plate S, the ring or arm-sleeve 'I and its set screw J -or its equivalent,all substantially as shown and described.

3. 1n shank-marking tools, the combination and arrangement of the marking-plate S and the frame I P Q with the elastic connections or plate-springs T '1,

all substantially as shown and described.
