TO ALL WH-OM-IT MAY GONCERN:

Be it known that I, JOHN L.McIN-T0sH, of Boston, in the county of .Su'olk, andState of` Massachusetts, have invented a new andl improved Pinking-Machine and Button-Hole Cutter;l and I do hereby declare that the following is a full, and exact description of the same, reference being had to the accompanying drawings, with letters of reference marked thereon; A l

The nature of my invention is a combination of a pair of pincersfor.scissors-handles,`with a pinking-tool; also'hwith a button-hole cutter, and gauge for the same, and a cutting-block, for the purpose'of cutting the edges ofcloth, leather, tc., into various shapes, and of cutting button-holes.

In the drawings annexed- Figure 1 is a side view of my invention Figure 2 is a vertical sectionof the cutting-part of the machine.

Figures 3 and 4 are lrespectivelya side view and an end view of two pinking-tools. y

And in the drawings annexed, A A, iig. 1,.are the lower handle and upper jaw, and vB B, g. 1,=are the upper handle and lower jaw of a metallic device of two levers, connected by and playing upon the rivet C, 'g: 1, and resembling a pair of pincers. D is a spring, rmly fastened, by the screw or rivet E, to the insideot' the lower handle, and playing loosely upon the opposite handle. The upper jaw contains, in its lower side a socket at F, g. 1, (dotted lines,) and bears, at right angles to the socket, a thumb-screw, G, called the toolscrew. In this socket ts the shank of the pinkng-tool, which tool diiiers in vno respect from an ordinary pinking-tool, except that it has a shorter handle. The lower jaw B bears in the socketseen in iigs. 1 and 2, the

4iat round block H, gs. 1 and 2, of brass, soft metal, wood, hardened rubber, or other substance,ealled thel cutting-block." This block is held to the jaw'by the set-screws I, figs. 1 and 2, called the blockscrew. This screw passes through an aperture bored perpendicn'larly through lthe bottom of the lower jaw B, which aperture is made of greater diameter than the screw. J, iigs. 1 and 2, is a piece of rubber, fon-which I sometimes substitute any other elastic substance, lying between the cutter-block H and its support. K, ig. 1, is a gauge, sliding back and forth upon the side of the handle B, guided by the pin L, fig. 1, whichworks in the slot seen in the gauge, and is held in place by the set-screw M, fig. l, called the gauge setscrew. N, iig. 1, isa tool for cutting button-holes, being a hollow truncated cone of steel, with its narrower and lower end sharpened, and bearing attached to its side a flat piece of steel, also sharpened at its lower end, and bearing a tang or Ahandle at its top. O is a representation of the face of this button-hole tool. P P are pinking-tools, made in the ordinary fashion, but with shorter handles, and below them are representations of their faces.

And the operation of my device is this: I place in the upper jaw apinking-toohbearing thedevice or figure towhich I wish to bring the substance operated on, and secure it there by the Atool-screw. Then, placingl 'the edge of a piece of cloth uponthe cutting-block, I press the two levers or handles together, and bring dorvvrrr the pinking-tool upon it. I find that there is not entire parallelism vb 'etween the two meeting-portions of the device. Pressing it more strongly, however, the-India-rubber spring J gives way, and the surface of the cuttingblock accommodates itself to the edge of the pinking-tool, the enlargement of the aperturetbrough which the lower part of the block-screw runs permitting the adjustment. The cloth or other substance operated on-isthus readily and clearly cut, when, withdrawing it, another portion of the cloth is submitted to the action ci' the tool, and the process proceeds. In the intervals of usingthe tool,'I rotate the cutting-block upon the -blockscrew I, thus preventing continued action of the sharp edge of the pinking-iron or other tool making a corresponding channel upon the face of the cutting-block. l

And wherTI desire to cut button-holes, I remove the pinking-tool, and replace it with the tool represented. Then arranging my gauge, so that the proposed button-hole may be at a. proper distancefrom the edge of the cloth, I proceed to cut the holes. And I sometimes have but one lever, the upper lone,and join it'to theupper jrawl And I sometimes dispense with the screw to hold the cutting-block, and keep it in placeiwith a flange or a spring.

And what I claim herein as my own invention, and desire to secure by Letters Patent, s- A machine or device for pinking leagher, cloth, SC., consisting of a lever, armed at one end with a. tool and o, tool-bearing socket, (the atter sdarranged as that the pinking-tool may be changed at pleasure,) in combination with the revolving block, when the same is supported and made adjustable by a spring beneath. 1.11 substantially as and for the purpose described.
