IMPROVEMENT IN' WASHER-CUTTERS.

Specification forming part of Letters Patent No. 210,553. dated December 3, 1878 application filed November 11, 1878.

To all whom it may concern:

Be it known that I, ALFRED J. PALMER, of Carlton, in the county of Orleans and State of New Y0rk,have invented a new and use-' ful Improvement in Washer-Onttcrs, Which improvement is fully set-forth in the followin g specification and accompanying drawing, in Which- Figure lis a view of the complete imple ment, and Fig. 2 a view of a cutter, seen as indicated by the arroW z in Fig. 1.

The object of my invention is to produce a tool complete within itself and at a low price, for cntting Washers out of leather, &0.; and it consists of a fiXed central point and adjustable cutters attached to a body formed simi larly to that of an ordinary bit-stock, by

means of Which the cutters are revolved and caused to cut out the washers aforesaid.

In the drawing, A is the body of the Washercutter, designed to be made of cast or malleable iron, cast solid in one piece, and having the usual SWVel breast-knob b and handle (Z, and provided with a slotted portion, B, at right angle to the axis of the stock or body A.

A steel center point, g, is cast in the metal of the stock and in the aXis of the same, and the oppositely-placed cutters h are adjnstable along the slots and held fast to the stock at any position of adjustmcnt by thumb-screws The. steel cutting-blades h are cast in the metal heads a by the metal being allowed to run around the shanks of the same and fill the hole l, and the heads of the clamping screws c are likewise cast in the heads a.

The slotted portion B of the stock is provided With grooves 0 next to and parallel with the slots, said grooves being on opposite sides of the stock, and each extending from the axial line of the same outward in opposite directions.

The metal heads a are provided With hooked lips f, which, when the heads are clamped to the stock, rest partially within the grooves 0, as shown in Fi g. 2. b

The shonlders e of the heads a, thatrest against the edge of the part B, are made concave, as shown in Fig. 1, so as to come to a bearing only at the outer edgcs, or at points at the greatest distance from each other, and the lips f rest upon the inclined sidcs of the grooves, as shown in Fig. 2, the tendency of which is, When the thnmb-screws are tighten ed, to drawthe shoulders e hard back against the stock, giving to the cutters a rigid stability.

The cntting-blades are inclined edgewise backward, as shown in Fig. 2, similar to the position in which a blade would be held 'in the hand when drawn across a substance for the purpose of cntting it. This position of the blades adds to the ease with which the implement is operated.

The stock atB may be graduated into fractions of an inch, that the cutters may be conveniently set to cnt washers of any desired diameter within the compass of the tool.

The breast-knob b is shown centrally sectioned, showing the form of the inclosed portion of the stock, which is provided With a collar, t, to prevent the knob from becoming removed. This part of the stock is first smeared over with a non-heat-conducting substance or separator for the iron, and the breastknob then cast upon the same, and When cold turns freely npon the stock as With a journal fit.

Washer-cutters as heretofore made are generally mere fixtures or attachments to bitstocks, and in order to use them it is neces sary to incur the eXpense attending the purchasing of a bit stock.

My Washer-cutter, as here described, is complete within itself and together, there being' no necessity of hunting up and putting' together parts, as is usually the case in order to compose a complete tool.

I claim as my inventionl. A Washer-cutter having the body A cast in one piece in the form of a bit-stock, provided With a centering-point, g, and unremovable breast-knob b, and adapted to receive detachable independent cutters L, substantially as described.

2. A stock, A, cast in one piece, provided with a rotary nnremovablc brcast knob, b,

Faroa. y

and slotted part B, stauding at right angles 4. The cutter-heads a, for holding theblades with the uXis of the stock and forming part h, provided with concave shoulders e a-nd thereof, substantialy as described and shown. hooked lips f, for the purpose set forth.

3. A Washer-cutter stock, A, having a slotted part, B, as described, provided With A. J. PALMER. grooves 0, made para-hel With the slots, one on each side of the part B, and extending from XVitnesscs: the axial line of the stock outward in opposite E. B. VVHITMORE, direetion Z. L. DAVIS.
