CAR-BOLSTER.
Specification of Letters latent.
Patented Nov. 30, 1909.
Application filed July 7, 1909. Serial No. 506,333.
To all whom it may concern:
Be it known that l, Cnannus H. ANDER- sox, a citizen of the United States, residing at Seattle, in the county of King and State of \Vashington, have invented a new and useful. Improvement in Car-Bolsters, of which the following is a specification.
My invention'relates to improvement in the construction of the companion bolsters interposed between car-bodies and their trucks.
.My object is to provide a construction of bolsters adapted for railway-cars generally and more especially for interurban electricrailway cars, which, besides holding the truck and car-body together with desired security, will permit relative rocking of the parts within comparatively wide limits and, furthermore, contribute to safety and smoothness of travel of the car-body during changes in angle either vertical or horizontal.
In the drawings-Figure 1 is a broken plan view of the car-body bolster; Fig. 2, a view on irregular line 22 in Fig. 1 showing the'body and truck-bolsters half in elevation and half in section and Figs. 3 and enlarge sections on lines 3 and 4 in The body-bolster 5, forming a part of the underlframe of the car-body, is provided at its under side with a centralsemi-spherical ball'socket 6 and two segmental bearingplates 7 each in the arc of a circle drawn from said socket and presenting smooth under faces slightly inclined toward the center of the bolster. The truck-bolster 8 is shaped at its ends, in practice, to fit the particular spring-supportedsecuring means th'erefor on the truck, which it is not thought necessary to illustrate. The bolster is provided toward opposite ends with bearings 9.
for frusto-conical rollers 10 registering with the bearing plates 7 and has a central opening 11 surrounded at its upper end by a fixed truck center-plate 12 having an annular groove forming a lower ball-race member filled with balls 13. Journaled in the opening 11 is a king-bolt i l-having anannular shoulder 15 and a head 16 of sphericalform fittin' the socket 6 in the body-bolsterfi Under t e shoulder 15 is an annular bearingplate 17 having an annular groove 18 in its under side forming an IIPPCI'llCG-lllfilllbfl cngaging the balls 13. The king-bolt is held against removal by tinut l9.
The ball-bearing described permits ready turning of the king-bolt in the truck-bolster, whereby the car-bodyand truck may turn with reference to each other without material friction. The ball-and- socket construction 16, 6 forms the connecting joint between the bolsters and avoids any binding or material wear thereat from rocking of the carbody or during changes in angle, as when the car starts upon or leaves an incline in the roadbed. The rollers 10 and segmentalplates 7 form coiiperating stops of an anti-friction nature limiting the rocking movements of the carbody.
My improved construction affords not only a most desirable pivotal connection be-.
tween the car-body and truck contributing materially to the comforts of travel, but tends to lessen injurious results in the case of certain accidents. For example, in the event of a collision between trains, causing one car to telesco m another, a car-body in rising would readily leave its truck and be freed from the weight thereof, thereby tending to diminish the force of impact between I the car-bodies; furthermore, the freed truck would probably be caused to strike against the truck of the other car and thus further tend to diminish the force of the impact of the car-bodies against each other.
lVhat I claim as new and desire to secure Letters Patent is 1. In combination, a car-body bolster having-a spherical socket in its underside, a truck-bolster, a king-bolt on the truck-holster having a spherical. head to fit said socket and an annular shoulder below said head, a
combination, a car body bolster, a truck-bolster, a king-bolt and a ll-bcaring grooved annular bearing. plate below said therefor 0n. the. truck-b01ster, and aball-anders oh the other bolster forming steps to socket bearing connection between the kingengage said surfaces'in the rockmg of the 10 boll: ifxlld bbdg-bolster. b d b 1 car-body.
