TOOLHOLDER Filed Feb. 27, 1945.

Patented Apr. 26, 1949 UNITED STATES ATENT OFFICE TOOLHOLDER Dale Hanes, Benton, Wash, assignor of one-half to Rossie Hanes, Benton, Wash.

1 Claim. 1

This invention relates to tool holders, and more particularly, to a detachable handle device adapted to be secured to a tool so that the tool may be manually employed.

A main object of this invention is to provide a tool holder of novel construction provided with improved means for detachable securement to a tool.

A further object of this invention is to provide a tool holder of simpl construction which may be readily fastened to or released from engagement with a tool.

Further objects and advantages of the invention will appear from the following description and claim, and from the accompanying drawings, wherein:

Figure 1 is a side elevational vieW of a tool operatively secured to a tool holder in accordance with this invention.

Figure 2 is a plan view of the tool and holder structure of Figure 1.

Figure 3 is a longitudinal vertical cross-sectional view of the too-l and holder structure of Figure 1.

Figure 4 is a cross-sectional View taken on line 4-4 of Figure 3.

Figure 5 is a cross-sectional View taken on line 5-5 of Figure 3.

Referring to the drawings, l designates a hollow handle member adapted to receive a portion of a tool 2, which may be a chisel, knife, file or other similar tool, for which it is desirable to provide a manual gripping means.

Tool 2 is provided with a tang portion 3, said tang portion being formed with a plurality of notches 4 on one edge thereof, the other edge being provided with a straight portion 5 and an inclined bearing portion 5.

Hollow handle member I may be built up of longitudinal laminations held together by rivets in a manner well known in the art. The internal bore of said handle member is provided with inwardly projecting tooth elements l substantially in the longitudinal median plane of said handle member, said tooth elements being adapted to interlock with the notches of the tool tang 3 when said tang is inserted into the handle bore. The tang is held in locked position with respect to said tooth elements I by a wedge member 8 adapted to be urged against inclined bearing Portion 6, said wedge member 8 being provided with a wedging surface adapted to wedgingly cooperate with hearing portion when wedge member 8 is urged in the direction of the tool.

Wedge member 8 is rigidly secured to a longitudinal bolt member 9 by locked, threaded engagement or other appropriate securing means. Bolt member 9 is provided with a head portion In, said head portion ill and the adjacent portion of the shank of bolt member 53 being contained in a knurled cap member I l which is freely rotatable With respect to bolt member 9, but which otherwise engages head portion for axial movement thereof.

Cap member H is formed with an externally threaded sleeve portion l2 which is in threaded engagement with the end Wall of handle member l. Said cap member is provided with an end wall [3 which exerts a thrust on bolt head portion l0 as the cap member is advanced inwardly with respect to the bore of handle member I. This thrust is communicated to wedge member 8 which in turn acts on inclined bearing portion 6 of tang portion 3 to lock said tang portion in engagement with tooth elements I. By reversing the rotation of cap member I I, wedge member 8 may be loosened and drawn away from tang portion 3 so that, by rotating the tool clockwise with respect to handle member I, as shown in Figure 3, said tang portion 3 may be withdrawn from the handle member. To insert the tool, the reverse process is employed.

Bolt head H] is positioned within cap H by forming an axial opening large enough to pass bolt head Ill therethrough in wall i3 and inserting shank 9 through the opening, said shank being drawn through sleeve portion I2 until bolt head It is positioned within the cavity in the cap. The axial opening is then sealed up by welding or brazing therein a closure disc M shaped to fit said opening. The resulting cavity is substantially the same in depth as the thickness of bolt head I!) so that cap I! can exert forward or rearward thrust on said bolt head.

While a specific embodiment of a tool holder has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention 3 other than as defined by the scope of the appended claim.

What is claimed is:

A holder for a tool handle having a serrated upper surface and having a lower surface em bodying a smooth inclined portion and a smooth straight portion, the straight portion extending rearwardly of the inclined portion, the said holder comprising a hollow, elongated gripping member adapted to encase the tool handle, a plurality of teeth within the gripping member adapted to dovetail with the serrated upper surface of the tool handle, wedge means slidable along the bottom of the interior of the gripping member to bear on the lower surface of the tool handle, the said wedge means having an upper surface that is complementary to the smooth inclined and straight portions of the lower surface of the tool handle, and means for urging said wedge means against the inclined and straight portions of the lower surface of the tool handle.

DALE HANES.
