HANDLEQFASTENING.

To all whom it may concern:

Be it known that I, lVILLIs F. HOBBS, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Handle-Fastenings, of which the following is a specification.

This invention relates to two-part combination tools generally and especially to the class of tools in which it is required that a part or parts of the tool be forged from steel of a high grade and fine quality, in order to insure durability in use and uniformity and reliability of temper, and another portion or portions of the tool require to be made from a much lower grade of steel, and my invention has for its object to devise a novel handle fastening, which will permit the use of two entirely different grades of steel, one only of which is required to have a high temper and which shall be simple and inexpensive and will produce tools adapted to stand the hardest kind of usage without injury.

With these and other objects in view I have devised the novel handle fastening which I will now describe, referring to the accompanying drawing forming a part of this specification and using reference characters to indicate the several parts:

Figure 1 is an elevation of a combination tool comprising a claw, hatchet and hammer, illustrating my novel invention; Fig. 2 a section on the line 22 in Fig. 1, looking in the direction of the arrows; Fig. 3 a section on the line 83 in Fig. 1, looking in the direction of the arrows, showing the high tempered member as formed and the two members assembled ready for uniting; Fig. f a similar view after the final operation and Fig. 5 is a view corresponding with Fig. 3, illustrating a slightly variant mode of locking the members against the possibility of movement.

10 denotes a member which may or may not be high tempered, in the present instance a hammer and hatchet, and 11 a member which may be relatively low tempered, in the present instance a shank and claw.

Specification of Letters Patent.

Application filed December 13, 1913.

Patented Oct. 6, 1914:.

Serial No. 806,456.

It should be understood, however, that my invention is equally adapted to the production of any other of the numerous types of two-part tools irrespective of whether the members are forged from different grades of steel. Member 11 is preferably forged from a relatively low grade of steel, as strength and toughness rather than a high temper are required.

12 denotes the shank which is preferably given a twist, as at 13, and 1 1- a claw formed at the outer end of the member.

Member 10 may be forged from a relatively high grade of steel and comprises in the present instance a hatchet 15, a bodylfi and a hammer 17 in longitudinal alinement. This member is forged to substantially the form shown in full lines in Fig. 3. The body is provided in one side with a recess 18 which just receives the other member and locates it centrally in the completed tool, the member 11 being fitted to the recess. At

the opposite ends or edges of the recess up turned lugs 19 are formed, which are adapted to be laterally bent or closed inward and downward upon member 11 as indicated in dotted lines in Fig. 3, and when struck a final blow to cause them to tightly grip member 11 and secure member 10 thereto, suilicient metal being allowed forthe lugs to cause their ends to abut firmly when closed down, as in Fig. 4. The operation of closing down these lugs is usually performed while the metal is hot and the mem bers are thus rigidly secured together. In order, however, to prevent the possibility of member 10 becoming loose on the shank I preferably provide additional securing means, as a transverse recess 20 in member 11 into which the lugs are closed down, as in Figs. 2 and 1-, or if preferred, the members may be locked together by a pin 21, as in Fig. 5.

Having thus described my invention 1 claim:

A tool comprising a metallic head provided upon one side with a recess which is rectangular in cross section and having at its edges transversely bent lugs integral with the head, and a metallic handle rectangular in cross section and fitted t0 the recess having at one side a transverse recess Which re- In testimony whereof I aflix my signature 1n presence of two Witnesses.

J ceives the lugs which thereby retain the head ILLIS HOBBS 5 rigidly upon the handle against iongitudi- W'itnesses:

nal and transverse movement with relation H. WV. MEADE, thereto.
