Application filed March 6, 1917. Serial No. 152,847.

To all whom it may concern:

Be it known that I, WILLIAM F. BROWN, a citizen of the United States, residing at Denham Springs, in the parish of Livingston and State of Louisiana, have invented certain new and useful Improvements in Tire-Tools, of which the following is a specification, reference being had to the ac companying drawings.

This invention relates to certain improve ments in tire tools and has relation more particularly to a device of this general character especially designed and adapted for use in connection with demountable split rims; and it is an object of the invention to provide a device of this general character having novel and improved means whereby a split rim may be readily expanded or contracted to apply or remove the rim from applied position.

It is also an object of the invention to provide a tool of this general character havingnovel and improved means which cooperates with a split rim in a manner to facilitate the requisite locking of the split end portions of the rim.

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

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

Inorder that my invention may be the I better understood, I will now proceed to describe the same with reference to the accompanymg drawlngs, wherein- Figure 1 is an elevatlonal view of a tlre tool constructed in accordance with an embodiment of my invention and in applied position;

Fig. 2 is an enlarged fragmentary view partly in elevation and partly in section of my improved tire tool as herein embodied;

Fig. 3 is an enlarged fragmentary view in elevation of my improved tool as herein disclosed and illustrating the end portion thereof opposite to that illustrated in Fig. 2; and

Fig. 4 is a fragmentary view in elevation showing certain of the parts in a. second position.

As disclosed in the accompanying drawings, R denotes a split rim of conventional construction having one end ortion provided with the tongue 1 adapted to interlock with the second end portion of the rim, and 2 denotes a pivot latch carried by the second end portion of the rim and adapted to coact with the tongue or extension 1 in a conventional manner for a well known purpose.

As herein disclosed, my improved tool comprises the reversely threaded elongated shanks 3 and 4 with which is operatively engaged a turn buckle 5 herein disclosed as comprising an elongated member provided intermediate its length with a recess or open ing 6 into which a suitable implement such as a screw driver or the like may be inserted in order to facilitate the requisite rotation of the turn buckle.

The outer end portion of the shank 3 is provided with the head 7. Said head 7 has the outstanding and longitudinally directed spaced ears 8 between which is positioned an .andwhich hook member 15 bridges or straddles the outer end portion of the arm 9 but separated therefrom. The outer end portion of the arm 9 and the adjacent hook member 15 of the arm 14 afi'ord coacting clamping jaws between which a marginal portion of the rim is adapted to be clamped especially when it is desired to contract the rim.

' The outer end of the second shank 4 is also provided with a head 16, the outer portion of which being pointed, as indicated at 17, and projecting beyond opposite sides of the head 16 and in longitudinal spaced relation relative to the head and the shank are the studs 18. The outer studs 18 are directed through the slots 19 disposed longitudinally of the metallic straps 20 while the inner studs 18 are adapted to be seated within the open slots 21 arranged inwardly of the slots 19 but in longitudinal alinement therewith. The slots 19 are of such a length as to permit the rear studs 18 to be free of the rear slots 21 when the straps 20 are moved forward so that the straps 20 may turn about the forward studs 18.

Pivotally engaged between the outer ends ally engaged with said ofl'set portion 24' of the straps 20, as indicated at 22, is the elongated arm 23 also having its outer end portion offset, as indicated at 24, and pivotthrough the medium of a rivet 25 or the like is the elongated arm 26 having its forward end portion returned to afford a hook member 27 adapted to overlie or bridge the outer end portion of the arm 26 so that the hook member 27 and the outer end portion of the arm 23 may contact to afford a clamping contact with the rim when it is desired to contract the rim to remove the same. When it is desired to expand a rim in order to apply the same the arms 14 and 26, or dogs as they also may be termed, are reversed which permits the outer or free ends of the arms 9 and 23'to contact with the rim so that upon the turn buckle 5 being properly rotated, the rim will be caused to properly expand.

In practice it often occurs that theton-gue 1 fails to properly lock with the opposite end portion ofthe rim. In this event, with my improved tool, the arm 23 together with the straps 20 are swung out of position so that the pointed end 17 of the headlfi may be brought into engagement with the tongue 1 so that said ton ue may be gently forced into place and he d rigid until the latch 2 can be turned in holding or locking adjustment. When my improved tool is in this position the operator has convenient access to the latch 2 so that the tongue may be bled, and it will also be obvious that my 4 invention is susceptible of some change andmodification without material departure from the principles andspirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter end thereof, coacting means carried by said second member and the strap for holding said strap against pivotal movement, and rim engagin means pivotally engaged with the outer en portion of the strap.

2. A tire'tool comprising a pair of coaxially disposed elongated members, means c0- acting with the inner end portions of said members for imparting movement thereto in a direction toward or from each other, rim engaging means carried by the outer end portion of one of the members, longitudinally spaced studs extending laterally from the outer end portion of the second elongated member, a strap provided with longitudinally disposed alined slots through which the studs of said second named elongated member are directed, one of said slots having an'open end so that said strap may have pivotal movement about the second stud when said strap is moved longitudinally in one direction, and rim engaging means carried by the strap. a y

In testimony whereof I hereunto .aflix my signature in the presence of two witnesses.
