Application filed April 26,
This invention relates to tools and more particularly to an improved method of making tools such as illustrated in my copending application Serial No.'616,327, filed F ebruary 1, 1923, and is a continuation in partof said copending application.
The objects of the invention are to provide an improved method of forming the frame portion of the wrench with a minimum oflabor and expense. I
The above and other objects may be attained by first providing a. transverse hole in the blank from which the frame member is'made, this hole being located at a predetermined point and acting as a key to all subsequent operations.
Two cutting operations are next performed, the cutters being moved into the metal from opposite sides of the frame, two slight slotting, cutting or punching operations removing corners of the metal left by the cutters, after which a broaching, keyseating or other cutting :tool is passed through the slot thus formed to widen a portion thereof, providing guideways or tracks.
The method thus set forth in general terms is illustrated in the accompanying drawings, in which- Fig. 1 is :aside elevation of the blank. from which the frame portion of the tool is formed;
Fig. 2 is a similar view after the first operation of providing the transverse hole in the frame; 3
Fig. 3 shows the second operation per formed by a cutter;
Fig. 4 shows the third operation which is also a cutting operation;
Fig. 5 shows the frame after the two triangular slotting, cutting, or punching operations; i
Fig. 6 shows the frame. after the guideway operation;
Fig. 7 is an edge elevation of the finished frame; and
Fig. 8 is a sectional viewof a partially completed frame made under a slightly dif ferent method. Y
Similar numerals'refer to similar parts throughout "the drawings.
The wrench to which the invention pertains is illustrated in my copending application above referred to, and the present method concerns more particularly the frame member illustrated at 1, and provided 1924. Serial No. 709,303.
with an integral jaw 2 and an integral handle portion 3.
This frame has an opening through its centralportion as shown at i to receive a lever, and is provided with the guideways or tracks 5 toreceive a movable jaw operated by the lever, all of which is illustrated in the copending application. above referred to, but which has no particular bearing upon the present application, ex-
cepting that the improved method includes the formation of the frame member to receive said other parts.
The blank shown in Fig. 1, may be formed by punching, forging or the like, and ineludes the frame portion 1, integral jaw 2 and handle portion 3.
The first operation comprises the forming of the transverse hole 6 in the frame portion of the blank by drilling, punching or the like at a predetermined point. The location of this transverse hole determines the finished shape of the frame portion and acts as a key to each subsequent operation. This hole may be forged in when the piece is forged, or punched when the piece is blanked.
The next operation is shown in Fig. 3, a
into the transverse hole 6 and substantially meeting or overlapping the cut made by the cutter 7.
From an observation of Fig. 4, it'will be seen that by providing the transverse hole 6,
the substantially triangular shaped portion of metal indicated at 11, is thus removed.
In thenext operation, the two substantially triangular portions of metal shown at 12 :and 13, are removed by slotting, punching or broaching or other similar operations, leaving the straight edges 12 and 13" respectively, as shown in Fig. 5.
The guideways or tracks 5 are then formed through the slotted portion of the frame, by drawing a breaching tool, a saw,
a slotter, or the like through the same, the finished tool member being shown in Figs. 6 and 7.
From the above, it will be seen that the transverse hole 6 is the key to the operations, as it furnishes the locating pointfor each subsequent operation on the frame, and also removes the triangularportion of metal indicated at 11, which could not be removed in any other way on a commercial manufacturing basis.
This transverse hole thus furnishes the key to the most practical and inexpensive method known for manufacturing the frame member for this class of tool out of one solid piece of metal upon a commercial basis. It furnishes an economical means of deepening the slot beyond the reach of a slotting cutter, in that it removes the triangular portion of metal, indicated at 11, without removing the back wall. It furnishes an absolute and unvarying locating point for all subsequent operations upon this member.
Fig. 8 shows a partly completed frame member made by a slightly different method, in which the transverse hole is not provided in the frame to start the operations.
In this form, the cutters 7 and 9 are operated in the directions indicated by the arrows or at right angles thereto, in the manner above described, slotting the frame as shown at S and 10 in Fig. 8, leaving the two substantially triangular portions of metal 12 and 13 to be removed by broaching, slotting, punching or other obvious method. It will be noted that in this form, a considerably greater amount of metal has to be removed at 12 than is necessary in the method above described. However, this method eliminates one operation, namely, the transverse hole.
The guideways or tracks may be afterwards formed by breaching, as indicated at 5 and as above described.
