EDGAR HUNTER, OF OSSIAN, INDIANA.
RIM BREAKER.
Application filed March 14, 1921. Serial No. 452,024.
T 0 all whom it may concern:
Be it known that I, EDGAR HUNTER, a citizen of the United States of America, and resident of Ossian, in the county of Wells and State of Indiana, have invented certain new and useful Improvements in Rim Breakers, of which the following is a specification.
This invention relates to improvements in rim breakers, and the object thereof is to provide apparatus for collapsing split rims for the purpose of removing and replacing tires, especially for heavy duty, such as is required in tire repair establishments, and to so construct the device that the rim may be positioned in connection therewith and the operations of breaking and collaps ing as well as springing the rim may be accomplished with but little physical exertion.
The objects of the invention are accomplished by the construction illustrated in the accompanying drawings in which:
Fig. l is a plan view of the invention in operating position and with a rim mounted in readiness for operation;
Fig. 2 is a detail view showing a cross section on the line AA of Fig. 1;
Fig. 3 is a similar detailed view on the line B-B of Fig. 1;
Fig. 4: is a perspective view of the invention; and
Fig. 5 is 2. Ian view of the invention shown in modi ed form.
Similar characters of reference indicate corresponding parts throughout the several views and having reference now to the same:
1 is a stationary supporting bar consisting of an angle iron, and 2 is a bracket fixed on the angle iron, there being a U-shaped reinforcement 3 and bolt 4; arranged in connection with the bracket for supporting and securing it in connection with the bar 1. Upon the end of the supporting bar adjacent the bracket 2 is secured a fixed jaw 5 having a stud 6 projecting upwardly therefrom and having a grooved lip 7. Upon the stud 6 is mounted an adjustable jaw 8 having a grooved lip 9 disposed opposite that of the fixed aw.
A primary lever 10 having an integral U- shaped stirrup 11 formed at one of its ends has pivotal connection bet-ween the extending arms 13 and 14: of the bracket 2, there being aligned bolts 15 and 16 extending through the lever and opposite end of its stirrup respectively forming pivotal connections. A secondary lever 17, having formed at one end thereof an integral U-shaped stirrup 18, has pivotal support in the stirrup 11 of the primary lever 10, there'being a bolt 19 extending through both stirrups securing them together. The secondary lever has mounted in connection therewith a pivotal jaw 20 having a grooved lip 21, a bolt 22 mounted in the stirrup and extending through the jaw serving as the pivotal support therefor. The jaw 20 has an upwardly extending stud 23 upon which is mounted an adjustable jaw 24 having an extending grooved lip 25. The stud 6 has a nut 63 and the stud 23 has a similar nut 23 by means of which the jaws 8 and 24 are respectively clamped into engaging position.
In using the invention the supporting bar 1 is rigidly positioned horizontally in a vise 26, or in any suitable manner, affording rigidity. A tire rim 2'? is positioned with its ends 28 and 29'arranged respectively on the jaws 5 and 20, said ends being secured fixedly thereon by applying the corresponding adjustable jaws 8 and 24:, the nuts on the studs 6 and 23 being tightened to clamp the rim ends between the jaws. While the rim. is thus secured with its ends between the respective pairs of jaws, the primary lever 10 is turned upon its pivotal support so that the end 29 of the rim is drawn inwardly out of connection with the abutting end 28. In affecting this operation the lever 10 may be turned until its stirrup l1 enters the notch 1', made in the supporting member, as shown in dotted outline in Fig. 1. While the primary lever 10 is thus positioned, the secondary lever 17 is swung upon its pivotal support in the primary member causing the end 29 of the rim to lap the opposite end 28 as indicated in dotted outline in Fig. 1. While the rim is thus held positioned the tire 30 is removed and replaced in the usual manner. The end 29 of the rim is: replaced to its normal position by shifting the secondary and primary members to their former positions, the operator manipulating the levers so as to spring the end 29 into proper abutting relation with the opposite end of the rim.
In the modification shown in Fig. 5 the bracket 31 and fixed jaw 5 are integral or connected directly together, and a support ing bar 1 is removably secured to the member comprised of the bracket and fixed jaw.
In other respects the modification is similar to the construction previously described. In this form the supporting bar may be removed and the device utilized as a portable tool to be carried in the vehicle.
What I claim is:
1. In a rim breaker, a stationary supporting member including a bracket; a rim clamping means fixed on said member; a primary lever pivotally supported by the bracket; a secondary lever'pivotally supported by the former lever and adapted to be actuated thereby; and a clamping means pivotally supported by the secondary lever.
2. In a rim breaker a supporting member including a bracket; a fixed jaw on the supporting member having an adpistable aw in connection therewith; a primary lever having a stirrup formed at one of its ends pivotally connected between the arms of the bracket; a secondary lever having a stirrup formed at one of its ends pivoted in the stirrup of the primary lever; and a clamping means including a jaw pivotally supported in the stirrup of the secondary lever and an adjustable jaw in connection with the pivotal jaw.
In testimony whereof I afiix my signature, in presence of two Witnesses.
EDGAR HUNTER.
