TIRE AND Application led June 16,

This invention relates to an improved automobile tire and rim tool and it has reference to 'an article of this kind which is especially, but not necessarily, adapted for 6 the removing of the usual split band or rirg which is used in association with wheels.

Briefly, the tool is composed of two parts; the first of which is in the form of a lever 10 adapted to be operated by the person doing the work, this lever being constructed to engage and separate the split ends of the removable band; together with an adjustable anchoring device for maintaining the leverA in operating position. Y

My principal aim is to provide an exceptionally simple and inexpensive tool of this class, which is highly practical, compact and convenient, and thoroughly reliable under all conditions. Otherobjects and advantages of the invention will become apparent from the following description and drawings.

In the accompanying drawings forming a part of this-application, and in which llke numerals are employed to designate like parts throughout the same Figure 1 is a view in elevation and section showing the complete tool as it is used. Fig. 2 is a view somewhat similar to Fig. 1,t showing a further step in the operation of the tool.

Fig. 3 is a detail view with portions broken away and shown in section to disclose the details more plainly. I

Fig. 4 is a perspective view of one end of the bracing or anchoring arm. Referring to the drawings in detail, the reference character 1 designates a tire, the '40 reference character 2 the disk whee'l which is provided with the usual rim, the reference character 3 designates the movable slit band which is emplo ed in connection with the rim and tire, 4 esignates the enlarged central hub opening, and 5 the bolt holes which surround this opening.

The improved tool, comprises, as before stated, a lever' which is here shown as provided with a reduced portion 7 terminating in a hook '8 which is ada ted to'engage the slit over-lapped end of t e removable band 3. The' anchoring device, which acts somewhat asa prop, is represented generally by the ret'erence c aracter 9 and this comprises `with sai-d downturned en am moor...

me. serial no. 116,430.

A retaining nut 13 is employed for maintaining the parts in ad'usted position.'

It will be notice particularly from Fig. 4, that the part 12 terminates in a downturned or curved end 14, adjacent which areoutstanding stop pins 15. In practice, the downturned end 14 of the part 12 is inserted into one of the bolt holes 5 adjacent the main central opening 4 in the disk wheel. Then the screw 10,1s properly adjusted to produce the deslred leverage. Next, the hooked end Sis en aged beneath the Split ends of the expansi le band 3 and these ends are pryed apart and then back by swinging the lever as lndicated in Fig. 2, the band is lifted of, thus facilitating removal of the tire.

The advantages, construction, and operation are plainly evident `from the description and drawings, and a more lengthy description is-thought unnecessary.

Minor changes comin within the field of invention claimed may e resorted to if desired.v

Having thus described my invention, what I claim as new is 1. A tire and rim tool of the class described comprising a lever having a reduced hooked end, and a bracing prop therefore, said prop comprising a screw pivotally connected to the reduced end of the lever, a part into which said screw is threaded, a retaining nut in said screw cooperable with said part, said part terminating in a downturned end adapted to t into a bolt hole in a disk whee'l, and there being stop ins associated d) for resting lagainst the disk.

2. A tire and rim tool of the class described comprising a lever having a -hooked end, and a bracing prop therefor, said pro comprisin a pair of adjustably connecte arts one o whlch is pivotally engaged wit an intermediate portion of the lever and the other of which terminates in a laterall i' extending end adapted to fit into a bolt hole in a disk whee'l, and there being stop pins associated with said laterally extendin end for resting against the disk of the dis wheel.

Inv testimony whereof I affix my signature.

, ROY H. HATFIELD.
