SPECIFICATION formingpart of Letters Patent No. 494,942, dated April 4, 1893. Application filed September 24, 1892. Serial No. 446,848. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES THOMPSON, a resident of the oityof Syracuse, in the county of Onondaga, State of New York, have invented a new and Improved Car-Axle Frame for and in Connection with a Sectional Oar- Axle for Use upon Street Cars or Railways and other Analogous Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in sectional axles and frames therefor and it has for its object, among others, to provide a sectional car axle that can be operated insingle sections or by combining two or more sections as occasion may require.

It has for a further object to rigidly support each sectional axle on a parallel plane and in such a manner as to overcome undue vibration at the center connection of the axles and at the same time to permit each section to operate with the least possible friction when passing around curves.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings which, with the letters of reference marked thereon,form a part of this specification and in which- Figure 1 is a side elevation with a portion broken away showing my improvem -nt as applied for instance, to a street-car. Fig. 2 is a plan of the compression-plate detached. Fig. 3 is a plan of the frame with a sectional axle therein. Fig. a is aside elevation of several sections combined for use as acar truck.

Like letters of reference refer to like parts in all the figures of the drawings.

Referring now to the details of the drawings by letter A designates the frame, rectangular in form as seen in Fig. 3 and provided with the central cross timber A upon which are supported the boxes or bearings a for the adjacent journals of the sectional axles, being supported upon the end timbers of the frame.

13 are the sectional axles formed at one end with the journals 2) supported in the boxes or bearings a and at their other ends with the journals I) supported in the boxes or bearings a.

B are extensions or projections.

O are the wheels of known construction arranged upon the axles within the frame A adjacent to the end timbers A thereof as shown.

Referring now to Fig. 1 the application of my invention will be seen. D designates the bottom or frame of the car to the under side of which is secured the bracket E which is formed upon the are of a circle and is provided with flanges e through which pass the bolts 6' or other means which serve to secure the same to the frame of the car. This bracket has a curved slot or opening E in which works the extension B which is somewhat narrower than the said slot as seen in Fig. 1, for a purpose which will hereinafter be explained.

E' is a stop on the bracket. Between it and the said extension is arranged a spring F of any suitable character as for instance, a rubber block as seen in Fig. 1.

G is a box or frame connected to or extending from the front portion of the frame Aand at its other end pivotally supported upon a pivot 9 supported in the cars it of a plate H which is provided with the longitudinal slots 71. in which work. the bolts I as seen best in Fig. 2, which serve to secure said plate to the car frame, as seen in Fig. 1 and not permit of longitudinal movement of the plate when occasion may require. This plate is provided with an upwardly extending portion H which fits in a recess (11in the car frame as seen in Fig. 1 which recess is somewhat longer than the said portion H which remaining space is occupied by the spring I of any suitable character preferably a rubber block as seen in Fig 1. With the parts thus arranged and the truck supposed to be moving in the direction of the arrow in Fig. 1, should the wheels meet with an obstruction or from any other cause he so acted upon as to under ordinary circumstances cause a shock, the said shock will be taken up by a spring I and thereby prevented from being transmitted to the car. This is accomplished in the following manner: The extension B being smaller than the slot in v This, connecting bar whiehmay be inch-eon,
