March 20, 1951 c. w. GINTER ADJUSTABLE HANDLE FOR TOOLS Filed May 1, 1946 IINV.ENTOR. HALE, W. GflNTE Patented Mar. 20, 1951 7 UNITED STATE Duration of ,Ohio

3 ,Gla'mis.

.-'.-..Mx; se inyentiqnrelat to 'h die for tools, particularly for electric or pneumaticdrills'or the like so -.that the tool can be readily held against jumping outof the operators handraaaux l y hand ana s e s a pistol grip handle being provided on such tools forthis purpose.

One object of the invention is to provide a handle which is adjustably mounted on the tool so that it can be rotated on the tool to any convenient position or a position required in view of adjacent structure limiting the possible positions that the handle may assume. In prior art devices it has been common practice to aflix an auxiliary handle to the tool but quite often the position of the handle is such that it is in the way of adjacent objects and the handle cannot be changed in position, or if it is of the type that is threaded into any one of a series of holes around the circumference of the tool it is a time taking procedure to unscrew it from one hole and screw it into another. These disadvantages are eliminated with my adjustable handle.

A further object of the present invention is to provide a simple arrangement whereby the handle is mounted on the tool for swinging around to any desired position where it can be locked for use.

Still a further object is to provide a simple and quickly operable locking means that can lock the handle in any one of an infinite number of positions around the tool.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of a tool to which my adjustable handle has been applied.

Figure 2 is a side elevation thereof with a mounting ring for the adjustable handle shown in section.

Figure 3 is a front elevation looking in a lefthand direction at Figure 2, and

Figure 4 is an enlarged sectional view on the line 4-4 of Figure 2 showing a locking shoe and. the means for looking it.

On the accompanying drawings I have used the reference numeral to indicate an electric or pneumatic motor adaptable for performing various work such as drilling operations in which case a drill chuck I2 is mounted on the shaft M of the motor. A tool motor of this character usually ,Aro Equipment corpora 2,545,655 21 f- I j v IAnJ s'rABLE Ennis-ma To oLs Charles w.dimer,Bryan 0 i ?i11ie i i has-apistol grip handle It for the-purpose'of holding the tool, the handle having a trigger l8 for controlling an electric switch or'a compressed J lv A tool of the'kind'just disclo'sed cannotbeheld with only "one hand conveniently and especially when large drills are being usedthe tool is apt to twist out of the hand of the operator. An auxiliary handle can be provided which is a great aid in preventing the undesirable twisting of the tool out of the operators hand as the operator can then use his other hand on the auxiliary handle to hold the tool firmly in both hands. Heretofore auxiliary handles, however, have not been adjustable so that they can be conveniently and quickly projected in any direction from the tool.

My invention comprises provision of an auxiliary handle 20 which is mounted on the motor Ill by means of a band 22 having a boss 24 internally screw threaded as shown in Figure 4 to receive a stud 26 on the inner end of the auxiliary handle 20. The band 22 seats in a groove 28 around the housing of the motor 18 and the ring may be held assembled in the groove by an end plate 30 detachably mounted on the motor housing as by screws 32.

The ring 22 is normally freely rotatable on the housing of th motor it] but may be locked relative thereto by 'means of a locking shoe 34. The locking shoe 3 frictionally engages the bottom of the groove 28 whenever the handle 20 is rotated for screwing the stud into the boss 24. This frictional engagement of the shoe 34 with a portion of the bottom of the groove 28 causes the An auxiliary handle adjustable in the manner disclosed provides for readily unlocking by a twist on the handle 253 so that the handle can be moved to any position where it does not interfere with adjacent objects during drilling or other operations. When the new position is reached the auxiliary handle may be quickly locked again by slight rotation in the opposite direction, thus making for a convenient rigid auxiliary handle that can be quickly adjusted in a minimum of time.

Some changes may be made in the construction and arrangement of the parts of my device with out departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

1. For use with a tool comprising a motor having an annular groove itherearound and ahandle projecting from said motor at a position spaced from said groove, an auxiliary handle comprising a ring rotatably mounted in said groove, "a handle elementcarried by said for locking said ring in said groove.

2. For use with a tool comprising a motorjhaving an annular groove therearound and a handle projecting from said motor at a position spaced from said groove, an auxiliary handle comprising a ring rotatably mounted in said groove,-a;ha.nd1e element carried by said ring, and means for locking said .ring ,in said groove, said means being operated by rotation of .said handle element.

.3. For use with a tool comprising a motor having an annular groove therearound and aihandle projecting .from said .motor at a position spaced from said groove, an auxiliary handle .comprising a ring rotataloly mounted "in said groove, a

handle element carried by said ring, and means for locking said ring in said groove, said means comprising a portion of said handle element threaded in said ring and a shoe in said annular groove and engaged by said portion of said handle element.
