BOLT.

Application filed June 16, 1927. Serial No. 199,318.

This invention relates to certain improvements in bolts and it is an object of the invention to provide a device of this kind having associated therewith a holding member or nut which may be readily and conveniently applied thereto in a manner to avoid a threading operation.

The invention consists in the details of construction and in the combination and ar rangcment of the several parts of my improved bolt whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein Figure 1 is a view in elevation of a bolt constructed in accordance with an embodiment of .my invention, the coacting work be ing diagrammatically indicated by broken lines- Figure 2 is a View in side elevation of the structure as illustrated in Figure 1;

Figure 3 is an enlarged fragmentary view partly in section and partly in elevation of illustrating the wrench engaged with the nut.

As disclosed in the accompanying drawing 1 denotes the shank of a bolt having threaded on one end portion a head 2 although, if preferred, said head may be integrally formed with the shank. The opposite end portion of the shank 1, as herein disclosed, is enlarged transversely and has its outer or free extremity rounded, as at 3, on substantially a quarter circle from one side of the shank to the other. This enlarged portion of the shank 1 adjacent the outer end of the rounded extremity 3 and at opposite sides of the shank is provided with the notches or recesses 4 separated by an intermediate partition or septum 5. These notches or recesses 4 are open at their outer ends and to the side or portion of the shank at which the outer or high point of the rounded extremity 3 terminates. These notches or recesses have their inner portions arranged in axial alignment substantially radial of the shank 1.

I The nut N is of a cap type and has one slde open and adjacent to each of its side edges this cap nut is provided with the inwardly disposed lugs 6 which are adapted to be readi y received within the notches or recesses 4 when the nut N is substantially in a quartered position or relation with respect to the shank 1. The head 7 of a socket wrench is then engaged with the nut N whereupon the nut is turned outwardly until the side wall of the nut "opposed to the open portion is brought substantially into contact with the shank 1 or the enlarged portion thereof and when in this position, the nut N is effectively held against displacement with respect to the shank 1.

The inner portion of the side wall 8 of the nut N adjacent the free side edges is provided with the rounded outstanding extensions 9 which serve to facilitate the requisite turning or swinging movement of the nut N when the bolt or shank is properly applied to the work and thus assuring the assembled shank and nut to have requisite clamping or holding action with respect to the work.

I find in practice that my improved bolt is especially adapted for use in connection with a tire clamp although I do not wish 9 to be understood as limiting myself to, this specific or particular use.

In practice- I also find it of advantage to employ the washers or shims 10 which are adapted to be interposed between the head 2 and the work whereby the efiiciency of my improved device is materially increased.

From the foregoing description it is thought to be obvious that a bolt constructed in accordance with my invention is particularly well adapted for use by reason of the parting from the principles and spirit thereof and for thisteason I do not wish to be understood as limiting myself to the pre- 7 tion, said nut having one side open to faciliinto said engagement of the lugs within the net-asses, said nut when 1n :1 second position having its side opposed to its open side substantially in contact with the shank.

2. In combination, a shank provided at one end portion with opposed sides having open recesses, and a caplike nut to receive said end portion, said nut being provided with inwardly directed lugs engaging within the recesses when the nut is in applied position, said nut having one side open to facilitate said engagement of the lugs within the recesses, the side of the nutadjacent to the outer portion of the open side of the nut being provided with outstanding extensions.

In testimony whereof I hereunto affix my signature.

SCOTT L. WILSON.
