HAND GRIP FOR TOOLS.

Application filed January 7, 1921.

To all w 7mm t may concern:

Be it known that I, WARREN S. BnLLows, a citizen of the United States, residing in the city of llllorcester, county of Worcester, and Stateof l/iassachusetts, have invented certain new and useful Improvements in Hand Grips for Tools. ot which the following is a specification. l

This invention relates to improvements in hand grips for tools and particularly to hand grips for brace wrenches, brace bits and similar' tools.

The object of the invention is' to provide a hand grip which is simple in construction, inexpensive to manufacture, and which may be quickly and easily attached to the shank of the tool and held against longitudinal movement with respect thereto. rlhe invention further has for its object to provide a vhand grip consisting of a plurality of interengaging parts which are maintained in engagement with one another by the assemblage of the parts without the use of extraneous means. Further objects 0f the invention are to provide a hand grip which is durable and eilicient in use, and which will present a neat and attractive appearance.

In the accompanying` drawings forming part of this speciiication. wherein I have shown two preferred embodiments of my invention for the purpose of illustrating the principle thereof,-

Figure l is an elevation al view of a brace bit provided with a hand grip constructed in accordance with and embodyingr my invention;

Figure 2 is a longitudinal sectional view of the hand grip as applied to the shank of the tool; and

Figure 3 is a sectional view taken on the line III-III of Figure 2.

For purposes of illustration I have shown the invention as applied to a brace bit, but it is oi course to be understood that the invention is not limited to this particular' type of tool as it may be employed in connection with tools of other types.

.Referring to Figure l, l represents the shank of a brace bit of the usual type, which shank is bent in the well-known manner to form an offset portion to which is secured a hand grip 2. As shown in Figures' 2 and 3, the hand grip comprises a pair of sleeves 3 preferably formed of metal, adapted to rotatably engage the shank l and having their inner ends spaced from one another.

Serial No. 435,648.

IVithn this space is a member t engaging an annular groove 5 formed in the shank l. The member 4c is preferably U-shaped, as shown in Figure 3, to permit it to be readily positioned within the groove 5. Mounted uponthe sleeves 3 is a third sleeve 6, preferably formed of wood or the like, the bore of which frictionally engages the outer surfaces of the sleeves, whereby the parts of 55 the hand grip will be firmly secured to one another. In order to more eliectually maintain the sleeve 6 in fixed relation to the sleeves 3, the outer surfaces of the latter are roughened. as indicated in Figure 2. The outer ends of the sleeves 3 are preferably spun outwardly so as to engage the ends' of the sleeve 6 as indicated at 7, F ig. 2; and the length of the sleeve 6 is sufficient to maintain the adjacent ends of the sleeves 3 prop- 7 5 erly spaced from one another.

When the several parts have been thus assembled, the hand grip, comprising the pair of sleeves' 3 and the sleeve 6, will be held against longitudinal movement with respect to the shank l by the member 4 which engages the groove 5 of the shank and the annular recess formed within the hand grip between the spaced inner ends of the sleeves 3.

lVhile I have illustrated and described my invention in connection with a preferred embodiment thereof, it will be understood that I do not intend to limit myself to the specific embodiment shown but that I intend to cover my invention broadly in whatever form its principle may be employed.

Having thus described my invention, I claim: a

A tool including a shank having an annular groove formed therein, a pair of sleeves rotatably engaging said shank and having their outer ends spun outwardly, a third sleeve the bore of which frictionally engages the outer surfaces of the pair of sleeves, said third sleeve being engaged at its ends by the outer spun ends of said pair of sleeves and being of a length suihcient to maintain the vadjacent ends of said pair of sleeves spaced from one another, and a U-shaped member located between the adjacent spaced ends of said pair of sleeves and engaging said annular groove.

In testimony whereof I have affixed my signature to this specilication.

VARREN S. BELLQWS.
