PROCESS FOR MAKING TDOLS.

Original application filed November 19, 1914', Serial No. 872,926.

Specification of Letters Patent.

1916. Serial No. 89,259.

To all whom it may concern:

Be it known that we, HENRY B. Barman, a citizen of the United States, residing at lVallingford, in the county of Rutland and State of Vermont, and Cnrrronn i1. Bmnnn, a citizen of the United States, residing at lVabash, in the county of Wabash and State of Indiana, have invented new and useful Improvements in Processes for Making Tools, of which the following is a specification.

This invention relates to an improvement in processes for making tools and more particularly to hoes, shovels or similar implements, involving the subject matter which was divided out from our co-pending application, Ser. No. 872,926, filed November 19, 1914i.

The object of the present invention is to provide a process for constructing implements of the nature set forth whereby the cost of production may be substantially reduced and incidentally an implement of great strength and durability result therefrom.

The invention consists of the several steps and operations substantially set forth in the following specification and particularly pointed out in the claims.

Referring to the drawings:

Figure 1 illustrates a side elevation of a strip of metal preferably embodying the initial step in the construction of an implement.

Fig. 2 is an end elevation of the strip illustrated in Fig. 1.

Fig. 3 is a detail view of the strip illustrating the second operation as having taken place.

Fig. 4 is a front elevation of a hoe in the course of construction and substantially embodies the operation following that illustrated in Fig. 8.

Fig. 5 is a side elevation of the completed work member of a hoe.

Fig. 6 is a perspective view of a shovel constructed in accordance with the process embodying this invention.

Like numerals refer to like parts in all views of the drawings.

In the drawings, 8 illustrates a strip of metal having an enlargement or rib 9 arranged longitudinally of said strip and substantially at the center thereof, said rib be ing of any preferred conformation but preferably convexly curved as illustrated in Fig. 2, and disposed substantially symmetrical with respect to the opposite faces 10 and 11 of said strip.

The strip embodying the construction recited may be and preferably is formed be tween suitable rollers in the manner well known to those skilled in the art. r he dimensions of said strip and said rib may be varied in accordance with the implement for which the same is intended. For instance, if it is intended for a hoe, as illustrated in Figs. d and 5, the width of said strip, from the edge 12 to the edge 13 thereof, which is somewhat thicker than the finished hoe will be made, is made somewhat narrower than the work member 14 of said hoe and likewise the length of the strip 8 will besubstantially shorter than the combined length of the work member 14 and the finished shank 15 of said hoe.

The next step in the construction of a hoe is preferably to remove predetermined portions of the material constituting said strip upon opposite sides of and contiguous to said rib 9. The portions just referred to will be indicated by the notches 1'6 and 17 in Fig. 3, thereby leaving a portion 18 of said rib 9 extending beyond the remaining portion of the strip 8, which remaining portion constitutes the material from which the work member of the implement is to be formed and the portion 18' constitutes the material from which the shank of the implement will be formed.

The next step in the operation of forming a hoe is to forge'the material into a shape as near like the finished work member is to be, as possible, after which said work member is finished OK in the manner desired. During the forging of said work member the remaining portion of the strip 8 on opposite sides of the rib 9 is worked out together with said rib portion contiguous thereto so as to provide a working edge at 19 of substantially equal thickness throughout while at the rear edge of said work member the rib still retains a greater portion of its previous dimension'as at 20. The portion 18 of the rib 9 is also forged and drawn out by reducing the size thereof to the length necessary for the finished shank as will be seen in Fig. 4, said rib being slightly tapered after which said shank may be bent to the desired angle with relation to the work member, that is, if the implement is to be formed into a hoe the shank will be bent substantially as indicated in Fig. 5, extending at right angles to the work member 14.

If it is desired to make a shovel, as illustrated in Fig. 6, instead of a hoe, the process will be substantially identical with that hereinbefore set forth up to and including the form shown in Fig. 3. i

The next step, however, in this form of implement consists in forming the work member 21 of the shovel substantially as was the work member of the hoe, but the portion 18 of the rib instead of being drawn out as was the one illustrated in Fig. 4, may be split as indicated by the line a a Fig. 2, from the extremity 22 of said member to the juncture 23 of said member 18 with the work member 14 and forming forward and rear portions 24: and 25 respectively.

These portions 24: and 25 are then forged into a suitable shape, preferably as indicated in Fig. (3 to form a socket 26 into which the handle of the shovel, not shown in the drawings, may be inserted and secured.

In an implement formed in accordance with the above described process, the weak.

points so often present in implements formed by welding the work member and shank to gether from separate pieces of material will be entirely eliminated owing to the fact that the shank and work member in the present implement are formed from a single piece of material requiring no welding whatever in any part of its construction.

The advantages resulting from the construction hereinbefore described consist in the formation of a very strong, durable implement with the expenditure of a very small we claim and desire by Letters Patent to secure is:

1. A process for making tools which consists in forming a strip of metal with an enlargement extending longitudinally through the center thereof and disposed substantially' symmetrical. with respect to opposite faces of said strip, then in removing predetermined portions of the material constituting said strip upon opposite sides of and contiguous to said enlargement, and in i subsequently forging the remaining portions of said strip into the form desired.

2. A process for making tools which consists in forming a strip of metal with a rib extending longitudinally substantially through the center thereof, then in removing predetermined portions of the material constituting said strip upon opposite sides of and contiguous to said rib, and then in forging the portion of said rib which was contiguous to the removed portions of said strip into a shank and the remaining portion of said strip into a work member.

In testimony whereof we have hereunto set our hands.

HENRY B. BARDEN. CLIFFORD A. BARDEN.
