RIM TOOL.

Application filed January 12, 1922.

To all whom may concern:

Be it known that we CI-mnLns HmnAnn and lVARREN Hrnnann, citizens or the United States, and residents, respectively, of Hudson Falls in the county of lVashington, and State of New York, and Fort Edward, in the county of l l ashington, and State of New York have invented a new andImproved ldim Tool, of which the following is a full, clear, and exact description.

This invention has relation to tools and particularly refers to a rim tool tor automobile tii which is designezl as a means for facilitating the association and disasseciation of tires and rims in a simple expeditious and efficient manner.

Heretol ore tools of this character have been devised for this purpose, but have been found wanting in many respects due to the fact that they have failed to overcome certain contingencies. t is therefore the principal object of the present invention to produce a rim tool which will completely and effectually handle the rim to facilitate the disassociat-ion of the tire therewith by shifting and disengaging the locking means at the rim joint and contracting and holding the rim in contracted condition while the tire is removed; facilitating the association of the tire and rim by erianding the rim, and shifting and intercngaging the locking means at the joint.

As further object the invention afiords means for compensating for the deflection oi? the ends of the rim at the joint where the same have been bent or otherwise distorted to normally lic out oil true alignment.

its a still itilrther object the invention con templates a comparatively simple and inc):- peric ivc tool which may be arranged to occopy a. mininuim amount ol' space when not in use whereby the same may he readily carried in the tool box of a vehirlc for use on the road. and which will l'oi'm a. useful part of the equipment of garages. repair shops and service stations.

l ith the above recited and other objects in view, the invention resides in the novel. construction set forth in the following specification particularly pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other Serial No. 528,747.

Referring to the drawings by characters of reference A designates one of the common forms of demountahle tire rims which is split as at B an d provided with one of the common Forms of locking means for rctwining the ends in loc e l condition to hold the rim in ring torrn within the tire. h peci'lh cally the locking n'ieaus ernhedics a slot in one of the rim terminals and a lug l) pro-- vided with an ofiset extremity l v which engages within the slot D.

The tool which constitutes the invention includes av pair of rim clan ping members dos ignated generally by the characters 10 and 11 which are connected together for relative movement. The member 10 comprises a base plate 12 provided on its under side with depending torwardly projecting laterally spaced arms 13 preferably forming integral elements thereof. The member 10 further includes clamping jaws 14; hinged to the opposite sides of the base plate 12 by a hinge pin 15 which passes through aligned pairs of knuckles 16 and 17 'lormed respec tively on the base plate and clamping j The upper extremity oi the jaw. 141- are pro vided with spaced pairs of rim engaging hooks 18 by means of which the member associated with the rim. A clamping bolt 19 is passed through aligned apertures 20 in the jaws lt for locking and retaining the rim engagaing hooks in clamping relation to the rim. T he inner or rear portions of the arms 13 are provided with aligned bearing openings 21 in which a transverse shaft 22 is mounted and upon which a sprocket wheel is arranged between the arms 13 and keyed as at 2% to the shaft. A. ratchet 25 is keyed to the shaft 22 at the outer side of one of the arms 13 and the shaft 22 proects therebeyond and is provided at its outer extreme end with a multi-ttaced extremity 26 with which a wrench or crank may be associated for rotating the shaft. The outer or forward tree extremities of the arms 13 are apertnred to receive a transverse stub shaft 28 upon which an idler roller 29 is mounted and arranged between the arm terminals and a sprocket chain 30 is trained over the sprocket wheel 23 and idler roller 29. A pawl 31 is pivotally mounted as at 32 on one of: the arms 13 and is normally engaged with the ratchet 25 by a lealt spring 33 to limit the rotation of the shalt for turning movement in one direrti a when engaged therewith. The pawl 31 is provided with a. pair o't spring engaging in s 3 1 and 35 in order to provide means for rcspc :tively throwing the pawl into and out oi" engagement with the teeth of the ratcnet when desired.

The member 11 comprises a base plate -10 which has hinged to the opposite side edges thereof. a pair of: clamping jaws 4-1 by means oi a hinge pin 522 which passes through aligned pairs of knuckles a3 and 4A formed respectively on the base plate and the clamping jaws. The upper extremity of the jaws -t1 are provided with spaced pairs of rim engaginghooks 4:5 by means of which the member associated. with the rim. A clamping bolt 4:6 is passed t ough red rtufies in the aws 4:1 tor locking rim engaging hooks in clamp I rim. The outer or rear end of the base plate 40 is provided with de iiending spaced hinge lugs which receive therebctween a spaced pair of hinge lugs ll) of a complementary base plate and a hinge pin 51 is assed through the lugs 48 and 49 to hingedly connect the complementary base plate 50 with the base plate 40. The complem mary base plate 50 is provided with depending and forwardly orojecting laterally spaced arms 51 which are connected at their forward ilroc extremities to the sprocket chain 30 by one of the link pins 52. The threaded shank 53 of a wing screw 54: extends hrough a threaded aperture 515 in the coinplemcntarv ase plate 50 and the inner end of the shank is swiveled to the base plate 40 as at whereby rotation of the wing screw in opposite directions will respectively eii ect the advancement or relative separation oi the base plate L0 and complementary base plate 50.

In operation of the tool. when it is desired to remove the tire from the rim, the members 10 and 11 are attached to the rim A at opposite sides the joint B by engaging the clamping jaws 14 iand il therewith. In attaching the members to the rim. the link pin 52 which connects the arms 51 with the sprocket disposed at the o1 er portion oi the idler roller 29. The tool is then ready for operation to effect the removal of the tire by associating a wrench or crank with the multitaced extremity 26 of: the shaft 22 and rotating the same. The initial operation of the device by the movement of the link pin 52 around the idler roller 29 effects a relative separation oi": the ends of the rim to shil't the offset extremity F into a position to be removed from the slot 1). The next movement of the link pin indicated by the arrow in Fig. 3 effects a downward move-- of one rim extremity with respect to men-.1 the other to disengage the offset extremity i from the slot. ilrt this point the pin F 2 toqeth r with the ttm'ward e tremitiesot the arms 51 ot the member 11 have been moved toward the underside oi" the idler roller and. continued movement oi the sprocket chain 30 wi l, advance the member 11 towart the member 10 and the terminal. of the rim A clamped thereby nncor the other terminal to elite-ct a radial contrznrtion oi? the entire rim. The engagement oi the pawl 31 with the ratchet on the shatt 22 will retain the rim in its contracted condition to perm it the operator to rcadil y remove the tire trom the rim.

l i hen the rim is thus contracted and it is desired to apply a tire thereto, the tire is placed over the rim and the pawl l. is swung upon its pivot 32 to dispose the same out o l engagement witl, the ratchet. 'lhe shatt 25.! is then rotated in the reverse direction to effect a relative separation of the members 1 and 11. and the resulting e pension fthe rim 3*. until the link pin 52 re ches 'tl'iQ tor-- ward or outer extent of its movement. (on-- tinned .inovemont oi the sprorket chain will effect the raising of the depressed rim. tel minal into alignment with the other rim terminal and at the same time the entrance of the offset F into the slot D. The movement of the sprocket chain. will cause the rim terminals to be at vanced toward each other and. the shifting ot the oitset terminal to locking engagement within the slot, thereby completing the application of the rim to the tire.

In event or? the rim being distorted as il lustrated in Fig. i", the same may be componsated for by manipulating the wing screw 5% to separate the base plate l-O from the complementary base plate to lift and dispose the rim terminals in alignment prior to the final step of the operation of advancing the rim terminals into engagement and the offset extremity F of the locking lug into locking engagement with the slot D as illustrated in Fig. 8. It will thus be seen that a rim tool has been provided for facilitating the association and disassociation of tires and rims in a. simple, expeditious and ellicient manner, together with means for colupensatiupior distorted rims.

in the modified form illustrated in Figs. 153 to 15 exclusive an eccentric mounted on a transverse pin 61 and provided with a manipulating handle 62 is carried by the 'l'orwin'dly projecting laterally spaced arms 51 of the member 11, while the pin 64 is mounted transversely in the laterally spaced ears 65 of the base plate 4h). The eccentric and link connection is employed in the modified form in lieu of the wing screw 54 for efi'ectin relative separation between the base plate 40 and the arms 51 to compensate for distorted rims and dispose the rim terminals in alignment prior to the final step of the operation to advance the rim terminals into engagement and the offset extremity F of the locking lug into locking enn'agement with the slot D as illustrated in Fig. 13.
