sion of an improved means'for connectingv the handle with the wrench so as to eliminate the chances of breaking the tool in the wrench.
Another object in view is to provide a wrench with a handle frictionally engaging the wrench, together with means for-varying the degree of friction so as to adapt the wrench to tools of different size and strength. A still further object of the invention is to provide a wrench for a tool which is formed with spring-pressed catches fitting into depressions in the wrench, wherebyv when more power is exerted on the handle than the tool will stand the catches will move out of the notches so as to allow the handle to rotate without rotatingthe wrench.
In the accompanying drawings :-Figure 1 is a top plan view of a wrench and handle, with certain parts broken away, the construction shown embodying the invention; Fig. 2 is a side view of the structure shown in Fig. 1, certain parts being broken away; Fig. 3 is an enlarged transverse section through Fig. 2 on line 3-3; Fig. 4- is an enlarged transverse section through Fig. 2 on line 4 4; Fig. 5 is a view similar to Fig. 3 but showing a slightly modified form of the invention.
Referring to the accompanying drawings by numerals, 1 indicates the wrench which may be of any desired construction for receiving a tool 2 which may be a tap, reamer or other tool. Connected with the wrench 1 is a handle 3 whichv may be provided with arms 4; and 5 is desired, as shown in Figs.
1 and 2, or may be provided with someother shape so as to adapt the same to the face plate of a lathe or an ordinary chuck. Arranged in each ofthe arms are a number of parts which act for connecting the handle 3 with tool 2. As these parts are duplicate a description of the parts shown in the arm 5 will equally apply to-parts in the arm 4.
It will be observed that arranged in the arm 5 1s a reciprocating member 6 which may be termed' a catch, the same being formed with a rounded end 7 fitting into a correspondingly rounded socket 8 inthe end of the tool 2. The member 6 is provided with a reduced extension 9 over which one end of a spring 10 fits.f The opposite end of spring 10 to that engaging the reciprocatv ing member -6 is caused to press against a Washer 11 which in turn presses against an externally threaded nut 12. The washer 11 is provided with an indicating extension 13 fitting into the slot 14 so as to indicate the position of nut 12 and consequently the degree of tension on spring 10. As shown in Fig. 1, a plurality of graduations 15 are provided for indicating the proper tension for different size tools 2. The idea of providing the graduations 15, spring 10 and associated parts is to allow the friction between the catch 6 and tool'2 to be sufficient for turning the tool 2 for properly operating the same but to be not sufficiently strong to break tool 2. Before tool 2 will be broken the pressure on arms 4 and 5 will cause the reciprocating member 6 to move out of socket 8 and thus allowthe handle to be free to rotate without rotating the tool. It is evident that when a small tool is used the compression spring- 10 must be very small, while for a large tool the compression may be up to the limit of the spring.
The nut 12 is threaded exteriorly so as to engage the threads 16 arranged interiorly of arm 5. The nut is provided with a square `or many-sided aperture through which the shaft 17 passes, saidshaft being, of course, of the same shape as the aperture in the nut, the shaft shown in the drawings being square. It is evident that a round shaft could be used With a key or other form of shaft provided the nut 12 could travel dur# ing the rotation of vshaft 17. Shaft 17 is provided with a stop 18 and a threaded thumb member 19 whlch is screwed on to the end of the shaft. Nut 2O is provided with a threaded extension or boss 21 which acts as a bar for shaft 17, said shaft having an enlarged portion 22 which rests in the nut 20. Whenv the member 21 is rotated in one direction the nut 12 will be forced toward catch 6 and when rotated in the opposite dip rection the nut will be forced away from the catch 6', thus regulating the tension.
When the slot 14 is arranged on top as shown in Fig. 1, a covering member 23 is provided which is held in place by a suitable screw or pin 24. However, preferably the slot 14 is arranged on the under surface of the handle and the cut-away portion 25 is left uncovered or bare. Wrench l may be of any desired construction but preferably the upper end is solid so as to provide ample material in which the sockets 8 are formed. A washer 26 is arranged at the upper end of wrench l and is held in place by a suitable screw 27, said washer overlapping part' of the handle 3 so that the handle cannot be moved off ofthe wrench until the washer 26 has been removed.
What I claim is:
l. In a device of the character described, the combination with a tool, of a handle therefor provided with a catch frictionally engaging said tool, a spring pressing against said catch, an exteriorly threaded sleeve arranged in said handle, said handle being formed with a threaded portion for receiving said sleeve, said sleeve having an opening therein, and a rotatable bar itting in said opening, said opening being of such shape as to cause said sleeve to-rotate when the bar is'rotated and to slide along the bar, the adjustmentof said sleeve being for varying the tension of said` spring.
2. In a device of the character described, the combination with va tool provided with rounded depressions, a handle for said tool, said handle having va. portion surrounding part of said tool, a reciprocating catch formed with a rounded end, an arm projecting into said rounded depression whereby the catch may be forced from the depression when suiiiclent side pressure is applied thereto, a spring acting on said catch for holding the same in said depression, a traveling member for. varying the tension 0f said spring, and a fixedl rotating member engaging said traveling member for rotating the same.
3. In a device of the character described, the combination with a tool, of a handle therefor, a catch arranged in said handle, said catch frictionally engaging said tool, a spring pressinc` against said catch, said handle having a threaded portion, an interiorly threaded sleeve arranged in said threaded portion and pressing against said spring, said sleeve being formed. with a ing, a shaft extending through said squared opening, and means arranged for rotatingly supporting said shaft, whereby when said Shaft is manually rotated said sleeve will bek moved and the tension of said spring will be varied.
4. In a device of the character described, the combination with a tool, of a handle therefor, a catch frictionally engaging said tool, a spring pressing against said catch, said handle being formed with a slot, a washer engaging the end of said spring, said washer being formed with a projection extending into said slot and indicating the position of said spring, and means arranged 1n said handle for varying the ycompression of said spring, said means moving said washer.

5. In a device of the character described, the combination with a tool holding member provided with a depression, a handle mounted on said tool holding member, a reciprocating pin adapted to be forced into said depression, said reciprocating pin moving radially of said tool holding member, a spring for normally holding said reciprocating member in said depression, said spring being arranged in said handle, a traveling member arranged in said handle for varying the tension of said spring, vand a rotatable square openy member engaging said traveling member, j
said rotatable member having a thumb portion at the end of said handle whereby when l JULIUS DUNN ER. Witnesses: e Y
