To all whom imag-concern:

Be it known that I, PAUL I1. PFIJAGER; a

' citizen of the United 'States of numerica, and

resident of Chicago, Cook county, Illinois;- have invented a certain new anduseflrl'lm prominent in Axle-Generator Supportsyoi which the following is a'specification.V

My invention re'latesto improved meansr Cnc of the objects of my invention is to" provide a support in which-'these wearing parts are reduced to' a minimum, andl in which the vsupporticonsists of al single integral casting secured to the frame' of the' car truck. These and other objects of'nry involition will vbe more clearly understood by having reference to the accompanying 'di-aw# ings in which I have illustrated one embodiment of my invention, although, of course,`

it will be understood that'my inventionv is not liinitedto theparticularshape and form oil the casting shown in these-drawings, but that .f'arious modilications can bem'ade and still come within' the scope ofiny invention.

Figure 1 is aplan* view of my improved support. Fig. 2 is a sectional View taken* on the line 2 2 in Fig. 1.. Fig.: 3 is an end View' of the device. Fig. 4 is a detailed side View of' the frame. Figs. 5 and Gare detail viewsi I represent a portion5 of the frame` of the frame consists of the 'side sill 9 and theinter mediate longitudinal braces 10'fand '115 In the usual construction the end sill dips" downward, as indicated in Fig.j 3, and'the car axle is supported in suitable bearingsl hung from the side" frames, as indicated in Fig. 2.

In the usual construction the axle generator is located outside of the end sill and driven by a belt on a pulley on theca'raxle' In order to so mount the generator, I provide an integral casting 13 which is'rectangular in shape, as shown in Fig. 1, and also dips downward,.as shown in Fig. 4.' This casting is provided with two supporting extensions 14 andl, -which are' securely bolted zto the

intermediate bars

10 and 11. As shown, these arms are setinward to a slight degree, this being forth'ereason that it is necaessary forv the castingA tocle'ar the brake re'- llease springs 16. Of course, if these springs were set inwardfarth'er' on-the end sill, it vioirld'notbe necessary 'to' oiset'the casting `infthis manner; Connecting the two lower horizontal side-sections of thiscasting area fpair ofbra-ee bars 17 and'lS. hese side members of the casting are provided with .rectangu'l'a-r' openings 19' within which are llocated alinin'g' blocks 20.- These alining blocks are provided withia Central portion ywhich provides a bearing 21 for the rock shaft22-.- These spacing blocks are' secured to the casting 13 `by means ofthe bolts and. nuts 23. Thek axle 'generator 24 is mounted upon'thisfrock shaft 22v in the well known manner, being provided with a pair of down iwardly extending legs 25 through which the rock shaft 22" passes." The generator pulley 26 is connected witht the axle pulley 27 by :means 0I' the belt 28, Whereby'power is transinitted from the' axle to the generator. In order to properly aline-the generator pulley with the axle-pulley it' is merely necessary to properly adjust the alinement blocks 20 within the-fran'1e'-l3.y Inorder to mount the generator securely upon this rock shaft 22, I provide any suitabley means, such as a tension rod 30 which passes through an opening 1n thecastin'g 31 carried by therear connectiiigbar of the supporting castingand is secured atits forward end t0 the frame of the axle generator. A spring 32 is mounted on this rod, and this rod is threaded and provided with 'a'n adjustable nut 33 which bears against the spring, whereby on tightening this `nut the generator can be' rocked back Ward so as to tighten the bolt 28, While when the nutis' loosened the spring: tension Jforces the generatory in the opposite direction to loosen the belt.

IVhil'e I have-shown' one particular means 'for holding the generator in place on the rock-shaft, it-is, of course'7 understood that any suitablemeans can be employed for this purpose: v

In order'to makea more rigid connection 4between the support 13 and the car truck frame, I provide an-ofset portion 29'which is adapted to extend beneatlrtlie end sill 9` and thus grip the same, and in this manner providing a very rigid and eflicient support for the axle generator.

It will thus be seen that I have devised a very simple support comprising a single i'ntegral casting, and in which substantially all the wearing parts are eliminated. The only wear would occur on the bearing for the rock shaft 21 in the alinement blocks 20,

and in the usual construction a bushing is provided which surrounds this shaft whereby the entire wear comes on this bushing.

While I have illustrated and ydescribed one particular embodiment of my invention, it will be understood that I do not wish to be limited to the exact construction shown and described.

What I claim as my invention is:

1. In a car truck, a frame, an axle generator, and a support for said generator carried by said frame, saidsupport consisting of a `single integral casting independent of saidh frame.

2. In a car truck, a frame, a single integral casting secured t0 said frame, a rock shaft mounted in said casting, andan axle generator mounted on said rock shaft, said casting being independent of said frame.

3. In a car truck, a frame, a single integral ,casting secured to said frame, a rock shaft mounted in said casting, an axle generator v mounted on said rock shaft, and means for adjusting the position of said rock shaft in said casting to properly aline said axle generator, said casting being independent of said frame.

4. In a car truck, a frame, an integral casting secured to said frame, said casting comprising a pair ofmembers spaced apart, downwardl curved and longitudinally extending si e members, an end member extending between said side members, a rock shaft carried by said frame, and an axle generator carried by said rock shaft.

5. In a car truck,a frame comprising side members and an end sill an axle generator support secured to said frame, said support comprising a pair of supporting members secured to said frame, downwardly and rearwardly extending side members, brace bars y securing said side membersl together, a rock shaft mounted in said side members, and an axle enerator mounted on said rock shaft.

6. n a-cartruck, a frame comprising side members and an endv sill, an axle lgenerator support secured to said frame, said sup` port comprising a pair of supporting members secured to said frame, downwardly and rearwardly extending side members, brace bars securing said Side members together, a rock shaft mounted in said side members, an axle generator mounted on said rock shaft, and means for adjusting the position of said rock shaft in said side members.

7. In a car truck, a frame, an axle generatorsupport secured thereto, said support comprising side members spaced apart and secured at their ends to said frame, said members extending downwardly and rearwardly, and provided with an extending lug for gripping said end sill, and a shaft carried by said members, and an axle generator support mounted on said shaft.

8. In a car truck, a frame, an axle generator support secured thereto, said support comprising side members spaced apart and secured at their ends to said frame, said members extending downwardly and rearwardly and provided with an extending lug for gripping said end sill, a shaft carried by said members, an axle generator support mounted on said shaft, and means for adjusting the position of said shaft in said members. f

9. In a car truck, a frame comprising side and end sills, an axle generator support secured thereto, said support comprising an integral casting consisting of a pair of spaced side members, an end member connecting said side members, said side members extending downwardly and provided with a notched portion adapted to grip the end sill, means for securing said casting to the frame, and an axle generator supported in said casting. v

10. In a car truck, a frame comprising side and end sills, an axle generator support secured thereto, said support comprising an integral casting consisting of a pair of spaced side members and an end member connecting said side members, said .side members extending downwardly and provided with a notched portion adapted to 'grip the end sill, means for securing said casting to the frame, a rock shaft mounted -in` said casting, an axle generator mounted onv said rock shaft, and means for adjusting thel position of said rock shaft in said support.

11 In a car truck, a frame, an integral casting 'secured to said frame, said casting comprising a"pai-r.of members spaced apart,

`downwardly curved and longitudinally extending side members, an end member extending between said side members, and an axle generator supported by said integral casting.
