T0 @ZZ whom it may concern,.-
Be it known-that we, ERNEST E. KRENGEL and WILLIAM G. MOLENNAN, citizens of the United States of America, and residents of Nezperce, county of Nez Eerce, State of Idaho, have invented certain new and useful Improvements in Cold-Axle Setters, of which the following is a full and clear specification, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view showing our device applied to an axle; *ig 2, an end view of the device on the axle, Eig. 3, a detail perspective view of the lever or bar; Fig. 4, a detail perspective view of the shiftable fulcrum; Fig. 5, a detail perspective view of the hook, and Fig. 6 a detail perspective view of the gage parts separated.
The object of this invention is to pI ovide a simple and strong implement for straightening axles without heating them and without removing them from the vehicle, as more fully hereinafter set forth.
To the accomplishment of this object and such others as may hereinafter appear the invention consists of the parts and combination of parts hereinafter fully described, and particularly pointed out in the appended claims, reference being had to the accompanying drawings, forming a part of this speciiication, in w `ch the same reference characters designate like parts throughout the several views,
Referring to the drawings by reference characters, A designates a strong metal bar or lever which is provided along its under side with a central longitudinal strengthening-rib a, which makes the bar substantially T-shaped in cross-section. In the forward end of the web portion a is formed a hole a. for the reception of the pivot-bolt b of a yoke or loop B, which embraces the forward end ofl the bar and which has its lower end b made narrower in order to closely embrace the web poi tion a of the bar. In the upper end of this yoke is mounted a screw C, provided at its upper end with a hand cross-bar c and having swiveled to its lower end a bearingblock c', which block is adapted to slide between the vertical bais of the yoke.
Mounted to slide on the bar is a fulci-umblock D, whose upper edge is tapered and whose lower side is provided with a pair of fianges d, which embrace the opposite edges of the bar. A set-screw d may be mounted on the fulcIum-block to hold it in its adjusted position and to prevent it being shifted while in operation or sliding off the bar when not 1n use. At the rear end of the bar is mounted a -slidable hook E, which is provided with a hook portion e, adapted to extend over the up er side of the axle. This hook is also provi ed with a plate e, which rests upon the upper side of the bar, and with a pair of inwardly-extending flanges e2, which engage under the o posite edges of the bar and confine the hook to the bar, but permit it to slide lengthwise thereof. A set-screw e3 may be provided to lock a hook at its adjusted point and prevent it shifting while in use or sliding off the bar when notin use.
The device is applied to the axle as shown in Fig. 1, and when the hook and the fulcrumblock are properly adjusted it is simply necessary to force down the bearing-block c u on the spindle f of the axle. The yoke is swung up over the end of the spindle after the hook e is engaged over the main part of the axle. 1t will be observed that the hook and the fulcrum-block may be adjusted readn ily on the bar and, further, that byreason of the fact that they are attached to the bar the device may be applied to the axle very readily. The shape of the vbar in cross-section gives it great strength with a minimum of weight and at the same time affords a convenient arrangement of oppositely-extendirig iianges on which the fulcrum-block and the hook may be mounted.
In order that the angle of the spindle may be accurately determined during the act of bending it, we mount in the loop a gage-finger G, whose squared shank g wor ks through a vertical slot t2 in one of the uprights of the loop, the gage being held in its adjusted position by a winged nut H, tapped on a threaded extension g of the shank g. and bearing against the outer side of the bar of the loop through the medium of a washer.
What we claim, and desire to secure by Letters Patent, is
1. ln a device of the class set forth, the combination of a bar haw'ng oppositely-extending longitudinal flanges along its upper edge and a central depending longitudinal flange, a hook slidably attached to the oppo-` site longitudinal flanges, a fulcIum-block also slidably attached to said flange, and a spindle-engaging device consisting of a loop having vertical side bars embracing the side flanges of the bar and a reduced lower end embracing the central ange of the bar, a
f pivot-bolt extending through the reduced portion and the intermediate flange, a slidable bearing-block adapted to slide vertically between the side members of the loop, and a screw mounted in the upper end of the loop.
2. In a device of the class set forth, the combination of a bar carrying a slidable fulcrum-block and a slidable hook for the purposes set forth, a spindle-engaging member consisting of a loop pivoted to the forward end of the bar and having arallel side members, a pressure-block wor Iing between the side members and a screw for operating this block, and a gage-linger extending across the loop under the bearing-block and adjustable I5 nesses, this 12th day of January, 1906.
