WVILLIAM BEHRENS, OF ST. LOUIS, MISSOURI.

CAR-PEDESTAL.

SPECIFICATION forming part of Letters Patent No. 416,773, dated December 10, 1889.

Application and February 5, 1889.

To all whom, it may concern:

Be it known that 1, WILLIAM BEHRENS, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Car-Pedestals, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This pedestal is intended specially for streetcars. The pedestals have capacity for lateral movement relatively to the car upon anti-friction rollers and return to their normal position by the influence of gravity.

Figure I is an outside elevation of a pedestal, showing a wheel in outline. Fig. 11 is a vertical transverse section at II II, Fig. V. Fig. III is a vertical transverse section at III III, Fig. V. Fig. IV is a vertical transverse section at IV IV, Fig. V. Fig. V is avertical longitudinal section at V V, Fig. IV. Fig. VI is an under View of the sill-plate. Fig. VII is a top view of the pedestal. Fig. VIII is an inside elevation of the pedestal and body-sill. Fig. IX is an enlarged detail section at IX IX, Fig. V, showing the pedestal in its normal position, while Fig. X is a section on the same plane, showing the pedestal in its outer position.

1 is the Wheel 2, the axle; '3, the brass which bears on the axle-journal. 4. is the greasebox. No novelty is herein claimed in these parts.

5 is the sill-plate, secured to the sill by bolts 6. The plate has at each end two saddles 7, which are adapted to bear on anti-friction rollers 8. The saddles are so formed that the side 9 toward the center of the car-body fits against the roller when the pedestal is in its normal position, as-seen in Fig. IV, while the other side 10 of each saddle is inclined, so that it runs upon the roller when the pedestal moves outward.

The pedestal 11 has inverted saddles 12, I

soon as the side strain is removed from the Serial No. 298,788. (No model.)

pedestal the pedestal will be forced back by the weight of the car into normal position, as seen in Figs. IV and IX.

15 is a flange of the sill-plate, whose oflice is to exclude dirt from the roller-bearings.

In order to hold the sill-plate to its bearings on the rollers 8 and to limit the side movement of the pedestal, and also to assist in bringing it to its normal position, a bolt 16 passes vertically through the saddles between The socket Him the pasestal moves outward and inward. The bolt 16 passes through a rubber or other spring 19 beneath the saddle, and carries beneath the spring a cup shaped washer 20, bearing against the bottom of thespring and retained by a nut 21.

22 are studs on the pedestal, which occupy elongated cavities 23 in the sill-plate, and which may act to limit the side movement of the pedestals.

24 are the rods passing axially through the springs '25, and whose upper ends occupy the elongated holes 26 of the sill-plate and sill.

Fig. IX shows the pedestal in its normal position, while Fig. X shows it moved outward. The rollers 8 have collars 27 at the ends, which are adapted to bear against the ends of the' the rollers at the proper distance asunder, so

that if the pedestal should'be tilted when out of the normal position, so as to remove the weight from one of the rollers, this roller would not approach the other one and thus throw the rollers out of the proper relative position.

I claim as my invention- 1. A car-pedestal carrying rollers 8, resting in saddles of the pedestal and of the sill-plate 5, the saddles having inclines 10 .14, substantially as and for the purpose set forth.

2. The rollers 8, occupying saddles in the pedestal and sill-plate and having collars 27, substantially as and for the purpose set forth.

3. The combination, in a car-pedestal, of the bearing-rollers 8, working in saddles 7 12 ofv the pedestal and sill-plate, and the rocking bolt 16, with spring 19 and retaining-nut 21, substantially as and for the purpose set forth.

4:. A ear-pedestal, rollers upon the pedestal with their axes longitudinal, and a plate secured to the body-sill of the ear adapted to ride on the rollers and allowing transverse movement of the body on the pedestal, substantially as and for the purposes set forth.

5. The combination, in a oar-pedestalbearing, of a sill-plate 5 With saddles '7, adapted to rest on the rollers 8, a pedestal having saddles 12, adapted to receive the rollers 8, Collars 27 at the ends of the rollers, adapted to bear against each other and against the ends of the saddles, and T-headed swinging bolts 16, connecting the sill-plate and pedestal, substantially as and for the purpose set forth.
