Application filed March 27, 1928. SerialH'o'. 628,055.

To zZZ 'whom it may concern.'

Be it known that I, JOHN A. Sw`IT zER, a'

wardly of the

jaw

17 the' member is i formed with an

enlargement

19 the outer citizen of the United States, residing at \end of which is bifurcated at 20, with the Parr, in the county of Jasper, State of Indiana, have invented certainf new and useful Improvements in Bolt Holders; and l do hereby declare the following .to be a full,

clear, and exact descriptionof the invention,

such as will enable others skilled in the art vto which it appertainsto make and use the same.

This invention 'relates to toolsand articularly to tools for holding bolts w ile the nuts are being screwed on or o.

One object of the invention is to provide a device ofthis character which 1s particularly adapted for holding the 'bolts of an engine crank-case, and which will remain 1n position on the head of the bolt while the operator uses bothhands to manipulate the wrench bymeans of which the nuts are turned on or oj.

Another object is to provide a 'device of this character which will. bear against a portion of the crank-case so that the bolt' and tool will remain stationary while the. nut is bein turned.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a perspective view ofthe b olt v holding tool.

Figure 2 is a side elevation ofthe joined portions of the crankcase ofV an engine,

showing the tool engaged with the head ofl the bolt.

Figure 3 is a view looking upwardly at the parts shown in Figure 2, showing the manner in which the tool engages with the head of the bolt and with the side of the crank-case. Y

Referring particularly to the'accompanying drawing, 10 and 11 represents the anges.

of the

upper andlower portions

12 and 13, of the crank-case of an automobile engine, with the

bolt

14 disposed upwardlytherethiough and having the

nut

15 onl the upper en `The tool comprises a pair of members A and B, .the former of which is provided -with a

handle shank

16, at one end, and a

jaw

17 at its' other end, the inner face of the

shank

16 having. a

shoulder

18 for a purposewhich will presently appear.' In,-

.furcations `formed with transversely alin- 1n openings 21 toreceive the vpivot pin or bo t '22.

The member B is formed with-the handle shank 23., at one end, and/

fthe jaw

24, aty

the other end,' the latter' for co'o eration with the jaw" '17 to grip the hea of the

bolt

14. therebetween, as clearly seen in Figmember Bare transversely grooved, as'at 27, for the reception of the furcations ofthe

bifurcation

20, and also receives the pivot 22 therethrough, whereby the members A and B are pivotally4 connected together. The spring 26 normally urges the

shank

16 and 23 away from each other, and the

jaws

17 and 24C toward each other, with the result that the head of the bolt will be firmly gripped therebetween, and remain saI posltioned without the aid of the operator. @ne of the Shanks is arranged to rest against the side of the

lower portion

13 of the crankcase so that when a wrench is applied to the nut, on the upper end of the bolt, and the nut turned, any tendency of the bolt to turn will be prevented. Thus the operator may use both hands to manipulate the wrench,

parallel relation so that when engaged wit the opposite faces of the head of the bolt, they will stand parallel. Also, the opposite side walls 27', of the

grooves

27, serve to limit the opening movement of the jaws, with the result that the nut cannot rotate between the jaws. Any tendency of the bolt to turn will cause the toolto be swung so that one of its Shanks will engage the side of the 'crank-case, and thereby check such movement of the bolt.

To 'apply the device, it is only necessary to press, the shanks toward each other to separate the jaws, when the tool is slipped onto the head of the bolt and the Shanks released. The'spring 26 will urge the aws into firm engagement with the bolt hea thus ermitting Vthe 'operator to release. his hol from V-shaped spring 26. The

the tool, whereby the tool will maintain itself in bolt gripping position.

Vhat is claimed 1s:-

A bolt holding tool foruse in connection with an engine crank-case and comprising a pair of pivotally connected bolt `head gripping jaws and operating shanks, said shanks being arranged to bear against the side of the crank-case to prevent turning of the tool under the turning tendency of the bolt, and having cooperating stop means for limiting the opening movement of the jaws beyond a parallel position, the inner faces of the outer ends of the Shanks having shoulders, and a V-shaped spring between the Shanks and having its legs retained byv said shoulders for urging the jaws into gripping engagement with the head of the bolt and for supporting the tool in such position without external aid.

In 'testimony whereof, I aiiix my signature, in the presence of two witnesses.
