BENDING TOOL Filed Jan. 4, 1952 2 sheets-sheet 2 K Q n N Invenlar\ f1 Harney Patented Aug. 2, 1932 PATENT? OFFICE AUSTIN G. MARSH AND AUGUST IBILLEK, OF SPIRII\`|'GII1ELD, ILLINOIS BENDIG TOOL Application led January 4, 1932. Serial No. 584,744.

This invention relates to a bending tool which is intended particularly for 4use on vehicle axles butit is understood, of course, that the tool may be utilized for any kind of work for which it may be found adapted and desirable, such as in bending bars or beams. A

An important object of the invention is to provide, in a manner as hereinafter set forth, a bending tool of the aforementioned character embodying a novel construction, combination and arrangement of parts through the medium of which the axle or other work may be readily bent in opposite directions.

Another important object of the invention is to 'provide a bending tool of the character described which may be expeditiously adj usted to meet various conditions which may be encountered. Other objects of the invention are to pro Vide a bending tool of the character set forth which'will be simple in construction, strong,

v durable, eilicient and reliable in operation and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein Figure 1 is a View in side elevation of the bending tool showing the same operatively connected with an automobile axle for bending one end portion of said axle downward,

Figure 2 is a view in side elevation of the tool showing the same connected to an automobile axle for bending an end portion of said axle upward,

Figure 3 is a sectional view taken substantially on the line 3-3 of Figure 1,

Figure 4 is a sectional view taken substantially on the line 4-f4 of Figure 2,

' Figure 5 a view in top plan of the lever,

Figure 6 is a detail view in elevation of the saddle, and

Figure 7 is a detail view in the clevis.

Referring now to the drawings in detail,

elevation of it will be seen that the reference numeral 1 designates a portion of a conventional vehicle axle on one end of ,which is mounted a wheel 2. The axle yto be bent is elevated to make room for the bending tool therebetween by placing chairs 3 beneath the wheels onv said axle. A rack or service pit, such as are in common use in many service stations, obviates the use of the chairs above mentioned.

The bending tool constituting the present invention comprises a lever which is desig: nated generally by the reference numeral 4, said lever including a tapered portion 5 having a T head 6 integral with its free end. The lever 4 further includes an angularly extending large end portion 7 in the upper and lower sides of which are provided a plurality of transverse grooves 8. The reference numeral 9y designates bosses on the vertical sides of the end portion 7 of the lever 4 and extending transversely through said end por- Ption 7 is a series of openings 10.

A clevis 11 is detachably and adjustably connected to the endportion 7 of the lever 4 through the medium of the pin 12 which is selectively insertable through the` openings 10. The pin 12 is secured against accidental displacement by a cotter pin 13 inserted through an opening provided therefor in one end portion of said pin 12. The clevis 11 is engageable over the axle 1 and, of course, is adapted to swing on 'the pin 12. The inner side of the bightportion of the clevis 11 is rounded, as at 14, to assure proper engagementof the clevis with the top ofthe axle and to provide a rocking surface.

A rounded shim 15 is detachably mounted Y on the endportion 7 of the lever 4 for 4engagement with the lower side of the axle 1. On the bottom ofthe shim. 15 is a lug 16 which is selectively insertable in the grooves -V posed with either horizontal sides uppermost, depending on conditions.

The reference numeral 17 designates a substantially U-shaped saddle which is mounted on the axle 1 and which is provided with the eyes 18 on the free ends of its legs. The eyes 18 are for the reception of a pin 19 which is secured against accidental displace` ment by the cotter; pins 20 which are inserted through openings provided therefor in the end portions of said pin 19. The inner side of the bight portion of the saddle 17 is rounded, as at 2l to assure proper engagement with the upper side of -the axle 1 and to provide a rocking surface.

The reference numeral 22 designates a hydraulic jack which is mounted, when -the axle is to be bent downward as illustrated in Figure 1 of the drawings, in the lower portion of the saddle 17 on the pin 19. The saddle 17 is positioned on theaxle 1 to straddle the lever 4 adjacent the T head 6. The jack 22 is equipped with a bifurcated base 23, the bifurcations of which have their lower ends notched or recessed to accommodate the pin 19. The jack 22 further in cludes a rounded head 24 which is engageable beneath the adjacent end portion of the lever 4. While a hydraulic jack has been illustrated and described, it should be under.- stood that any type of jack which may be fouid suitable, such as a screw jack may be .use

When the axle 1 is toy be bent downward, the shim 15 is mounted inward on the angu- 'larly extending end portion 7 of the lever 4 and the clevis 11 is connected to said end portion 7 at a point outward of the fulcrum point of the lever which is provided by the shim. Then, the jack 22 is actuated and, in turn, moves the end portion 5 of the lever 4 upward toward the axle 1, said lever fulcruming on the shim 15 and the free end of the portion 7 of said lever is moved downward and away from the axle. Of course, through the medium of the clevis 11, the axle is bent downward.

As illustrated in Figure 2 of the drawings, when it is desired to bend the axle upward, the shim 15 is mounted on the outer portion of the end portion 7 ofthe lever and theclevis 11 is connected to the lever at a point inwardly of the shim. The saddle 17 and the pin 19 are dispensed. with and the jacket 22 is mounted on the head 6 of the lever 4. The bifurcations of the base 23 of the jack 22 straddle the lever 4. The head 24 ,of the jack 22 is engaged beneath the axle 1 and the jack is then actuated. When in use, the clevis 11 constitutes means for-mounting the lever 4 for swinging movement beneath the axle 1, said lever fulcruming on the pin 12. lVhen the tapered end portion 5 of the lever is swung downward by the jack 22, the end portion 7 of said lever is, of course, swung upward to engage the shim 15 beneath the axle and said axle is thus bent upward.

It is believed that thc many advantages of a bending tool constructed in accordance with the present invention will he readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the conibination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
