L. H. DOWE TOOL HANDLE April 11, 1944.
Filed May '7, 1943 /m/E/vroe: Eo M DOWE, 5,/ /vuy/W Patented Api". 11, 1944 UNITED STATES PATENT OFFICE TOOL HANDLE Leo H. Dowe, Waukegan, Ill.
Application May 7, 1943, Serial No. 486,024
tachable handle adapted to accommodate a variety of tools.
The object of this invention is to provide novel and facile means giving detachability between the tool and its handle. By means of this invention a single handle of convenient form is provided for a plurality of tools so that economy of cost and space is obtained, the combination being efficient and the detaching means being facile and certain.
While the invention is defined in the appended claim, the following detailed description, taken with the accompanying drawing, disclose a preferred embodiment of the invention with some suggested modifications.
Fig. 1 is a top plan view of the handle with tool aftixed;
Fig. 2 is an elevational view;
Fig. 3 is a vertical section on line 33, Fig. l;
Fig. 4 is a vertical section on line 4 4, Fig. 3
Figs. 5 and 6 are elevational views of tools diierent from that shown in Figs. 2 and 3, but fitting the handle;
Fig. 7 is a vertical section showing a modification of the handle;
Fig. 8 is an elevational view showing a modification illustrated in Fig. 7; and
Fig. 9 is a vertical section showing a further modication.
The tool handle is of T-form having a staff I and arms 2 and 3 extending opposite each other at right angles to the staff. The staff has a bore 4 therethrough from top to bottom, and the arm 3 has a slot 5 extending downwardly from its top and communicating with the bore 4. The bore 4 and slot 5 accommodate a tool 6 which has a stem extending through the bore and a shank 'l resting in the slot. The shank is at right angles to the stem and connected thereto by a bend or elbow 8.
The arm 2 has a set screw 9 threaded therein and positioned to engage the perimeter of the bend or elbow 8 on the tool, in such a manner as to hold the tool against displacement.
By reference to Fig. 3 it will be seen that upon backing out the set screw 9, the tool 6 will be disengaged, and may be removed upwardly through the stem.
It may be understood that the handle 3 will accommodate a tool such as a hollow screw wrench shown in Fig. 3; a screw driver 65 shown in Fig. 5; or a bit 66 shown in Fig. 6; all of which are merely illustrative of a large variety of tools which may be used.
The tools may have a cross section circular or polygonal in form, or of other cross section if desired.
The handle may also be of metal, wood, plastic or the like. Fig. 7 shows a modification in which the handle is made of plastic with a metal liner or bushing l0 molded therein, the bushing being threaded to accommodate a set screw.
A ferrule Il may be attached to the lower end of the stern by a bayonet joint, as specially shown. It has a bore coaxial with the bore 4 but of reduced diameter, so as to adapt handle to tools of lesser diameter than those for which the handle is otherwise adapted.
Fig. 8 shows a modification in which a diierent type of set screw l2 is provided. This set screw has an enlarged head i3 with a hexagonal socket I4 which will fit the shank end of any one of a number of tools such as 6 and 65, made of hexagonal bar stock. Thus the set screw can be manipulated by any one of several tools in the set.
It will be obvious that various changes may be made in the details of construction, within the scope of the appended claim, without departing from the spirit of this invention, parts of the invention may be used without the whole, and improvements may be added thereto while retaining the full benefit of the invention.
A tool handle having a stai and an arm eX- tending at right angle to the stair, the staff having a bore therethrough and the arm having a slot extending downwardly from its top and communicating with the bore, the bore and slot being adapted to accommodate a tool having a stem extending through the bore and a shank, connected at right angles to the stem by a bend or elbow, seated in the slot, and a set screw threaded in the handle and positioned to engage the perimeter of the bend on the tool in such a manner as to hold the tool against dis placement.
