scon thereoto y invention has for its ObJQGt to provide a simple, economical and efl'eotive' tool for breaking the joint in demountable rims for the purpose of removing or replacing ti TBS. Another object of my invention is to provide a combination tool for the purpose specified wherein certain of the parts are sold in sets whereby a series of rims may be operated upon with an actuating mechanism which is removable from one wt of the devices Mine other, thus a plurality of rims may be manipulatethandlocked up with a single actuating device.

With the above objects'in view the invention consists in certain peculiarities of con: struction and combination of the parts as hereinafter set forth with reference to the accompanying drawings and subsequently claimed.

In the drawings: Figure 1 represents a side elevation of a portion of a clincher rim having attached thereto-a tool embodying the features of my invention, the parts of the tool being to shown in position to break the rim. Figure 2 is a-Fplane .view of the same with parts broken away'and in section toshow certain structural features.

Figure 3 is a side elevation of therim to locking elements of the tool showing the same in position upon a rim which iscontracted and locked, the actuating lever ofthe tool being removed.

Figure 4 is a detail cross section of one of the rim gripping elements embodying a portion of the tool this section being indicated by the line 4-4 of Figure 3, and

Figure 5 is a detail fragmentary view of the lower portion of the actuating lever of- Said i001.

Referring by characters to the drawings A-A' represent the ends of a split 'rim'of any known type and at a predetemnined hand nut 6 whereby 'the se arable portions in Figure 3 of the drawings being locked predetermined distance from the ear 4 to distance from the joint between rim sec t10I15- A pair of grips 1-1"are fitted to thernn. As best shown in Figure 4 each of these grips comprise seble straps hav- 1 ing hooked ends 2 whic t over the rim bead and at an intermediate point the grips are formed with inwardly extended flanges 3 which rest upon the inner face of the rim. An upstanding ear portion 4 of the grip is apertured for the reception of a tie bolt 5, which he bolt is in threaded union with a of the rim grip are. adjusta ly fitted to the rim and held frictionally to prevent slippage, The grip member 1 as shown in Figurea has loosely mounted upon the bolt 5 a locking dog 7 which dog terminates with the hooked end 7' that is adapted to be folded over for engagement with the tie bolt 5 of the run grip 1'. When the rim sections A-A. have been contracted by manipulationof the two in which position they are shown by the dog 7. The tie bolt 5 has'mounted thereon a specmg sleeve 8 which is stopped at one end a form clearance space for the reception of the =5; lower end of an actuating link 9, which lower end is apertured for the reception of the bolt that constitutes a pivot connection therefor. 1 as The upper end of the actuati link 9 is provlded with a series of perfcratlons 9 for locking engagement with a key pin 10 that is fitte through any one of a series of apertures 10' formed. in the lower end of an actuating lever 11. The extreme end of the actuating lever 11, as best shown in Figure 5 is provided with a T-shaped slot 12 adapted for removable engagement with the he bolt 5 of the grip 1 there being a space becc tween the shank of the locking dog and the juxta-posed ear 4 of the'grip member for the reception of the slotted end of this lover. The T shape of the lever serves to make the lever reversible. The lever is adapted to be entirely removed from 1ts cooperate parts excepting the chain and pin,

and may be used in connection with other similar parts with arm of the T shapodslot,

therefore adapted to engage withv a bolt.

Thus it is unnecessary that the lever should 7 too be operated in one particular direction, it is reversible and the bolt may be engaged in either arm of the T shaped slot,

As best shown in Figure 2 of the drawings the lever is preferably constructed from a malleable strip folded upon itself so as to provide the necessary strength and the folded lower ends are each formed with a key hole slot as shown in Figure .5. The folded sections of the lever 11 are secured together an oiiset portion by a rivet 13, which rivet is formed with an eye head 13 that is pro vided tor the reception of one end of a chain to the lower end of which is attached the locking pin 10 as shown in Figure 1.

From the foregoing description it will be seen that when the parts are in the position shown in 1 should it be desired break and contract the rim member the ac 1 tuating lever may be first swung in the op posits dir ction from that indicated by the arrow 03. The joint of rim, to the pressure being put upon the lever and in this direction will open or spread the rim sections causing them to break out of alinement, The actuating lever is then swung in the direction indicated by the arrow a2 whereby the ends of the rim are contracted and folded upon themselves as shown. in Figure 3' of the drawings. Thus the tie bolts of the rim grips are brought together approximately a distance equal to the length of the locking dog. The locking dog is swung by hand to cause the nose of the locking dog to nest over the bolt 5 and its associated thimble 8 whereby, the gripping members are securely fastened in their contracted relation so as to hold the rim in the position shown in Figure 3.

Should it be desired to manipulate one or a series of: rims in a like manner the operator will then simply remove the pin 10 to free the link9 from the actuatinglever 11' and thereafter said lever can be readily extracted from its fulcrum engagement with the tie bolt 5 due to the key hole slot at its end. The lever is then utilized for coupling engagement with a similar set of rim grips and their associated parts, the locking dog 7 and link 9. This interchangeability of actuating mechanism is an important feature in repair shops where a number of rims are to be worked upon and thus a great saving in cost of rim tools is efiected where more than one tool can be economically put into use. Obviously in cases where a single tool only is used the removed feature of the lever 11 may be dispensed with.

Attention is directed to the fact that I provide a series of apertures in the link and lever whereby they may be pivotally connected by the locking pin 10 at predetermined distances from their fulcrumed points whereby the leverage or to *gle link connection is varied to provide or manipulating insane rims wherein a greater or less degree of power is required. lhus when a still rim is to be manipulated the leverage between the link and actuating lever is shortened so as to increase power and vice 'versa.

While I: have shown and described the structure of the tool minutely as to detail it is understood that changes in such detail s ructure may be eiiected without departing from the spirit of my invention,

l claim:

it. In a device of the class described, combination of alever made of a sir elongated piece of metal, bent at the raids and extending in substantially parall l stretches, forming a handle portion throughout which the stretches are in close contact and an actuating portion having a T shaped slot in the end thereof for cooperation with a bolt, arms of the receiving the bolt retaining the lever in engagement there with, the lever being reversible with the bol" whereby either arm of m may receive the bolt, the "lever havin the i:

series of spaced, apertures in its actuatn part and being deflected laterally betwee said actuating part and said handle, and a rivet exten m thru the laterally flected portion for securing the stretches c2. metal rigidly together, an eye rigid with said rivet, a chain carried by said eye and pin carried by said chain, "the lever being deflected laterally to facilitate movement of the lever without causing the lever to come in contact with the hub of the wheel.
