. provide a nail set both ends of which are harder than the intermediate portion of the set, and to provide a protecting shield, for the percussive end of the set, which shield is softer than the hardened, percussive end of the tool.
A further object of the invention is to provide, for the hardened, percussive end of a nail set, a polygonal sleeve, constituting a means for preventing the set from rolling about upon a support.
With the foregoing and other objects in view which will appear as the desgription proceeds, the invention resides in the combination and arrangement of partsand in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention. In the accompanying drawings,Figure 1 shows the invention in perspective; Fig. 2 is a longitudinal section; and Fig. 3 is an elevation, the constituent parts of the set being separated.
The set comprises an intermediate portion or body 1, knurled, or milled, as shown at 2, the body 1 merging into a tapering tip 3, havingin its end, the usual depression 4, adapted to -receive "the head of the nail. The opposite end;ofthe body 1 is formed with a reduced spindle 5, defining a shoulder 6 in the set. i v\ The tip 3 and the spindle!) are tempered or hardened to a greater degree than the body portion 1, the elements 3 and 5 ordinarily being tempered by a special process, or otherwise, to a violet blue. Over the spindle 5 is slipped, with a close driving fit, a sleeve 7, the sleeve 7 abutting against the shoulder 6. The outer end of the sleeve 7 is flush with the end face 8 of the spindle 5, the face 8 representing the percussive end of the tool. The sleeve 7, adjacent the end face 8 is tapered, as shown at 9, to expose the end face 8 prominently, to receive the blows of the hammer.
As denoted by the numeral 10, the sleeve 7 is of polygonal transverse section, the flat faces of the sleeve 7 outstanding beyond all other portions of the tool, as most clearly discernible in Fig. 2. The sleeve 7 is of softer material than the hardened spindle 5 which it surrounds.
\Vhen the nail set hereinbefore described, is laid upon a supporting surface, it will be seen that the flat faces 10, engaging such surface, serve to prevent the nail set from rolling about. The nail set is the more effectively prevented from rolling about, for the reason that the faces 10 of the sleeve '7 are located beyond all other portions of the.
tool. The hardened spindle 5 is well adapted to receive the blows of the hammer, and this spindle 5 is reinforced and strengthened, by the surrounding sleeve 7, which sleeve 7 is softer than the tempered or hardened spindle 5. The spindle 5, being hardened, is well adapted to stand the percussive blows of the hammer, a cracking of this spindle 5 being prevented, by the surrounding sleeve 7 which, being softer than the spindle 5, possesses a greater tensile strength.
Owing to the beveling or tapering of the sleeve 7, as shown at 9, the end face 8 of the spindle 5 is exposed prominently to the hammer, and there will be no appreciable battering of the periphery of the sleeve 7, adjacent its outer "end.
Obviously, the shoulder 6 formed at the line of union between the spindle 5 and the body 1, constitutes a support, against which the sleeve 7 abuts.
For convenience, I have described the invention in the form of a nail set, but it is obvious that the essential principles of the invention may be embodied in prick punches, solid punches, center punches, and in any other similar tool, the selection of a nail set being merely for the sake of pre senting one embodiment of the invention.
Havin thus described the invention, what is claime is 1. A driven tool comprising a metal body; and a metal sleeve surroundin one terminal of the body; the terminal having greater compressive strength than the sleeve, and the sleeve having greater tensile strength than the terminal.
2. A driven tool comprising a metal body;
prominently. 9
terminal having greater compressive strength 7 than the sleeve, and g the Sleeve having greater tensile strength than the terminal.
In testimony that I claim the foregoing 15 as my own, I have hereto aflixed my signature 1n the presence of two witnesses.
