Specification of Letters Patent.

Patented Jan. 4, 1916.

Application led August 20, 1914. Serial No. 857,720.

To all whom it may concern:

Be it known that I, WILLIAM F. Kmsnr., J r., a citizen of the United States, andvresident of Altoona, Blair county, State of Pennsylvania, have invented certain new and useful Improvements in Locomotives, of which the following is a specification.

My invention relates to locomotives of that type wherein the power used to rotate the driving wheels is transmitted to and through a jack shaft which is positioned between the prime mover and driving wheels.

Heretofofe it has been customary to make the bearing for the jack shaft similar to the bearings for the driving axles so that the jack shaft could be dropped downward into a pit by removing the frame strap u nderneath the journal box and dropping 1t out of the box.

My invention contemplates a jack shaft" ypositioned transversely to rotate in bearings at eithery of the locomotive andl adapted v end, the bearings being rigidly fixed-1n the lframe of the locomotive and having means whereby the jack shaft crank can be readily placed in position and removed without the usual difficulties associated with this type of 'power transmission device.

d The above and other objects and the novel features of my invention will be apparent from the following description, taken .in connection with the drawings, in which:

Figure l is a side elevation of substantially one-half of an electric locomotive'embodying my invention; Fig. 2 is an enlarged detail view partly in section showing the manner of mounting the jack shaft on the frame; and Fig. 3 is an end elevation of the parts shown in Fig. 2. l

Referring to the drawings, and particularly Fig. 1, each half of the electric locomotive or engine consists of a parallel frame members 10 and 11 about 34 long, two pairs of driving wheels 12 and 13 mounted on the axles 14 and' 15, two pony trucks comprising the pairs of pony truck wheels 16 and 17 mounted on the pony truck axles 18 and 19, and a jack shaft 20 between and substantially in line with the.,axles 14 and 15 and carrying two

gear wheels

21 and 22 into which the pairso of

pinions

23 and 24 on the axles of the

motors

25 and 26 mesh. Each ofthe gear wheels 21-and '22 is connected by suitably located connecting

rods

27 and 28 with the pairs of driving wheels 12 and-13 respectively..

feet 6 inches The bearings-for the jack shaft 20 consistl of circular holes 29 and 30 in the frame members 10 and 11 respectively into which the phosphor bronze bearing sleeves 31 are pressed. The bearing sleeves 31 are provided at one end with" exterior flanges 32 to limit their inwardmovement. For the purpose of keeping the bearing sleeves 31 from rotating a plurality of bearing anchor bolts 33 are-provided and are preferably located on thel underside thereof having the Shanks extending through the bearing and the heads countersunk therein with the securing bolts bearing against the underside of the .frame members. The faces of the journals adapted to engage the inner surfaces of the bearingl sleeves 31 are, in this construction, formed integral with the crank located on the jack shaft. The cranks in this conhubs 34, the exterior surfaces of which are designed to iit the interior of the -hearing sleeves 31 and are enlarged at their bases as at 3,5 to engage the flanges 32 on the; sleeves and space the gear wheels 21 and 2,2ffrom the frame members 10 and 11 respectively. The gear wheel hubs slide freelyI in the phosphor bronze sleeves which provide a suitable bearing for the gear wheels and the jack shaft 20 which is secured thereto.

The hollow hubs 34 have tapering axial openings therein to receive and fit the tapering ends 36 of the jack shaft 20. The jack shaft 20 passes through the wheel hubs and the ends thereof are threaded to receive the nuts 37, whereby the wheels are held to the shaft on the outside of the wheel center and 'thus the bearings on the inside of the wheels treating the shaft a longitudinal hole 40 is drilled through the same, the ends of which -are preferably plugged after the shaft is reassembled.

' The phosphor bronze bearing sleeves 30 are solid, ,that is, they are not cut in halves andif theywear considerably they maybe A replaced' by new ones after first withdrawing the gear wheels. This arrangement makes it easier to keep the shaft 20 in proper alinement and makes it no more difficult to replace the bearings. In case it is necessary to remove either of the gear wheels this can readily be done by first removing the adjacent side-motion spring 41, then removing the nut 37 and drawing out the wheel. The opposite wheel with the shaft 20 may readily be pulled out from the other side. Since there are no torsional strains transferred through the jack shaft 20, it is not necessary to provide the shaft and gear wheels with keys, which arrangement is commonly found in prior constructions of this type.

For the purpose of supplying lubricant to the bearing surfacesbetw'een the sleeves 31 and the hubs 34, an oil reservoir `42 is provided on the inner side of eacliof the frame `members 10 and 11 directly above the openl ing therein and is preferably made integral with the frame. Each of the lubricant containers 42 has a filling opening 43 for filling the reservoir from the outside of the frame and a larger opening 44 on the inside for filling the reservoir from the inside of the frame and for cleaning it out. Duets 45 extend through the bottom of the reservoir and register with perforations 46 in the bearing sleeves 31 to lead the lubricant to a recess 47 on the inner surface of the bearing sleeves 31 and at the top thereof between the said bearing sleeves and the hollow hubs 34 on the gear wheels.

The cab 48, one-half of which is shown in outline in F ig. 1, is secured and rests on the body bolster 49. The body bolster 49 has a pair of extensions 50 at each of its ends andl the underside of each extension is. provided with a lug 51 which fits the top surface of the side-motion spring 41 which rests in a saddle 52. The saddles 52 at each side of the truck aremounted at the ends of the truck bolster 53 which is supported by the side frame members 10 and 11. y

The particular cab supporting arrangement herein shown is made the subject-matter of a separate application.
