WRENCH ATTACHMENT Filed July 3, 1928 niiil A TTORNE Y Patented Oct. 29, 1929 UNITED STATES ATENT oFFicE AUGUST nnnuonz, or MINNEAPOLIS, MINNESOTA wnnncn ATTACHMENT Application filed July 3,

This invention relates to improvements in tool handles and more particularly bolt wrenches and the like such as employed on railroad track work.

One of the objects of my invention is to provide in a tool handle, such as a wrench, provision for manipulating the tool by two operators as when tightening or loosening a bolt.

Another object of my invention is to provide a tool handle attachment permitting an adjustable leverage for a tool or implement I including provision whereby the said tool and its attachmentv maybe operated by two 15 operators.

To enable others skilled in the art to more fully comprehend the underlying features of my invention, reference is had to the accompanying drawing forming a part of this specification in which Fig. 1 is a side view.

Fig. 2 is a front view.

Fig. 3 is a fragmentary detail showing a collar and its relation to the handle and attachment.

Referring now to the drawings, 5 designates an elongated tool shank having a bolt engaging head 6 of any design such as employed for ti ghteningand loosening bolts on railroad tracks. Theshank is provided with a plurality of apertures 7 for adjustably mounting an attachment consisting of a top collar 8 and a bottom collar 9 joined by a rear, flat bar 9 and connected by removable pins 10 passing through the said apertures.

The bottom collar 9 is formed with rearwardly directed, parallel cars 11 for supporting a pivot 12 on the lower end of an elongated lever 13. The upper collar is provided with a rear, preferably flat extension bar 14 which is adapted to slidably pass through a recess 15 through the lever 13. The bar lt is equipped with a coil spring 16 bearing against the lever and an outer head 17 on the end of said bar. The head is preferably removable so that the bar may be passed through the recess 15 and permit the coil spring to be positioned as shown.

The upper portion of the lever 13 is further provided with a bracket 18 to which is 1928.; Serial No. 290,261.

pivotally attachedasi at '19, a pairof-side handles 19, 20. Then not in use, the said handles 19, 20 may be moved to an inoperative or vertical position as shown in dotted lines by Fig. 2. 'The upperend of the levelis equipped with asingle'handle 21 of sufficient length to be gripped by both operators when the tool is'being used.

From the above construction, it will be seen that as each operator grips the top han dle 21 and a bottom or side handle, the shank of the tool may be manipulated, the coil spring tending to return the lever from the dotted line'to the full line position as shown by Fig. 1. It will be understoodthat in tightening orremoving boltsion railroad track I work, along leverage is necessary and as a. i rule two men are'requiredto manipulate the tool. Thebolt engaging headv ,6 must here I leased or movedback on the nut with each ditions the shank 5 andthe lever 13 move in parallelismuntil considerable power is exerted whereupon the'pivoted lever bears against the resistance'of the spring so thati this lever is somewhat inclined at an angle to the shank. The spring causes the lever to return to its parallel position, each time the shank is moved to the vertical or full line positionjshown in Fig. 1. This permits the I workto be done in a more efiicient manner, is much easier. for the workman and provides a tool whereby the workmen may function in unison. I 1

While I have shown and described myin vention with some'degree of particularity, I realize that various changes, modifications and alterations in the details shown may be resorted to. I therefore do not wish to be v limited or restricted to the precise and exact details shown, but reserve the right to make such changes as may fairly fall within the. scope offthe subject matter being claimed.

Having shown and described my invention, what I claim as new and desire to secure by Letters Patent is: I i j 1. In combination with a tool handle'hav ing a shank, spaced collars connected to said shank, a lever pivotally connected to the lowc er collar, a rearwardly extending flat bar 10 7o operation of thetool. Under ordinary conformed with the top collar extending through a recess in said lever, a coil spring on said fiat bar, side handles connected to said lever and a handle on the upper end of said lever.

' 2. In combination with a tool having a shank, a top collar and a bottom collar adjustably connected to said shank, an elongated lever pivotally mounted on the rear of the bottom collar, a bar formed with the top collar, said bar being movable througha recess in said lever, a coil spring on said bar against which said lever is operated when the tool'shank is manipulated and a handle for said lever.

3. In combination witha tool having a shank, interconnected top and bottom collars adapted to be adjustably fastened to said shank, an elongated lever pivoted to the rear of said bottom collar, a rearwardly extending flaI-tbar integral with the top collar passing through a recess in the said lever, a coil spring on said fiat bar, side handles connected to the lever and a top handle on the endof said lever.

4. In combination with a tool handle havin a shank, interconnected top and bottom collars adapted to be adjust-ably fastened to said shank, an "elongated lever pivoted to cars on the bOttOIH' collar, a rearwardly extending fiat bar formed with-the top collar adapted "to pass throughfa recess in the lever, a coil spring 'on said flat bar, a head on said bar engaging one end of the spring when the lever manipulated, side handles attached to said lever and a handle on the upper end of said lever. I

In testimony whereof I'afiix my signature.

AUGUST BEDUORZ.
