UNITED STATES PATENT OFFICE.

JOHN M. YOUNG, OF BALDWINSVILLE, NEW YORK.

MANUFACTURE OF METALLIC RAKES.

, SPECIFICATION forming part of Letters Patent No. 267,640, dated November 14, 1882, Application filed May 18, 1882. (No model.)

To all whom it may concern Be it known that I, JOHN M. YOUNG, of

Baldwinsville, in the county of Onondaga, in

the State of New York, have invented new and useful Improvements in Methods of Manufacturing Metallic Rakes, of which the following,

" taken in connection with the accompanying of metal, as hereinafter fully described, and

set forth in the claim.

The annexed drawings illustrate the successive steps necessary to carry out the aforesaid method or process, in which Figures 1 and 2 illustrate the method of obtaining from a crude bar of metal the blank from which the rake is formed. Figs. 3, 31}, and 4 are inverted plan views of the aforesaid blank, showing the manner of forming from the same the rakehead and its tan gs and Fig. 5 is a perspective View of the rake complete.

Similar letters .of reference indicate corresponding parts.

A represents the blank from which the rakehead and its tangs are formed. Said blank, having its central portion, a, wider than its end portions, 11 b,,may he obtained either by shearing or punching it out of a square or rect' angular bar oflmetal, as illustrated in Fig. 1 of the drawings, or by drawing or swaging out the end portion of a bar shorter than the rakehead to be formed, but otherwiseof sufficientlyincreased dimensions to admit of forging it into the shape of the blank A, as represented in Fig. 2 of the drawings. The projecting part of the central portion, a, I compress vertically toward that portion of the blank which forms the top of the rake-head, thereby distendiug.

said enlarged portion a laterally, as shown in Figs. 3 and 4 of the drawings. I then make in the center of said distended portion an incision, c, reaching to a point nearly or quite on a line with the adjacent face of the end portions, 11 b, and from the end of the incision c I out in opposite directions part way thelength of the central portion, a, as indicated by dotted lines (marked d) in the drawings. The portions e 6 thus severed I draw or swage out into two long prongs, and bend the same outward from the blank and bring them together at the proper point to form the braces e e and the tangs t t, the extremities of which are separated sufficiently to admit of inserting between them a Wedge for securing the shank in the socket of the rake-handle H, as illustrated by dotted lines'in Fig. 4 of the drawings. The teeth 8 s are forged or drawn out of the blank A in the usual manner.

I do not claim broadly the method of forming the shank of metallic rakes integral with the head thereof by cutting into a metal blank and drawing out the cut portions into the requisiteshape, as I'am aware the same has been carried out in various ways; but

What I do claim as new, and desire to secure by Letters Patent, is-

The within -described mode of formiug a rake-head and its tang of one piece of metal-i. 6., by first forming a blank, A, having its central portion, a, wider than its end portions, 1) b, then shearing the center of the said enlarged portion, as at c, and from said centerin opposite directions, as at d d,part way. the length thereof, and then drawing out lengthwise the sheared parts and bending the same into the requisite shapeto form the braces and tangs of the rake, substantially as specified and shown. I

Intesti inon y whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 15th day of May, 1882.

JOHN M. YOUNG.
