ROLL-ER SIDE BEARING FOR RAILWAY-CARS.
Specification of Letters Patent.
Patented April 9, 1907.
Application filed December 29, I906. Serial No. 349,983.
To all whom it may concern:
Be it known that I, FREDERICK B. T'owN- SEND, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Roller Side Bearings for roller side bearing of a strong, sim le, efll,
cient, and durable construction, in w ich the cap-plate may have an extended movement in respect to the bottom plate, in which the cap-plate may be automatically returned to its' normal position when relieved from load or pressure, and which will be composed of few parts, of simple form and construction, ca able of being cheaply manufactured.
1y invention consistsin the means I employ to practically accomplish this object or result-that is to say, it consists, in connection with a top or cap plate against which the body-bolster bears and a bottom or base plate secured to the truck-bolster and provided with an integral longitudinal recess 'or chamber'to receive a s'prin for restoring the cap-plate and rollers to t eir central position, of a pair of rollers interposed between the top and cap plate and having notches or teeth to engage the notches orteeth on the top and bottom plates, and a roller spider or frame cast in one integral piece andprovided with seats or bearings to receive the integral shafts or hubs of the rollers, and an integral 1 spring-engaging member projecting into the spring chamber or recess of the bottom plate and engaging the springs in said chamber or recess, so that the roller spider or frame and the rollers journaled thereon and the capplate meshin with the teeth or notches of the rollers be restored to their central or normal position.
My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described. 7
In the accompanying drawings, forming a part of this specification, Figure 1 is a peraspective view of a railway side bearing embodyin my invention. Fig. 2 is a central vertica cross-section. Fig. 3 1s a vertical longitudinal section. 4 is a plan view.
I with the top plate removed. Fig. 5 is a perspective view of the roller frame or spider, and Fig. 6 is a perspective view of one of the followers or bearing-disks interposed between the end of the spring and the springen'gaging member of the roller frame or spider.
In the drawings, A represents the cap or top plate, and B the base or bottom plate, which is secured to the truck-bolster of the car by bolls passig through the ears or lugs b of the base-plate. The base-plate B is'provided with integral lateral flan es or guides b, one engaging a corresponding integral flange or guide a of the cap or top plate and the other engaging a removable guide a fitting in a slot a of thedepending flange a of B B of the bottom or base plate B form a preferably two in number and which are furnished with short integral shafts d.
The rollers D are prefer'ably'of conical or frustum shape, and the tread B of the bottom plate and A of 'the top plate are preferably correspondingly inclined and curved. The rollers D are also furnished with teethlike devices d, on aging correspondin intermeshing teeth-1i e devices a and 2 to keep the rollers and top and bottom plates in proper engagement or mesh and insure the rcturnin of the to plate to its central position with the r0 ers and roller-frame or spider F.
cast in one integral piece and has seats or bearings fl prefer ably in the form of upright slots, to engage the short shafts (Z of the rollers D. The roller-frame or spider F has a cross -'bar f connecting its side bars f and is also provided with an integral springengaging' member f rejecting beyond one of the side bars into t 1e spring chamber or recess B of the bottom or .base-plate B. This spring-chamber B contains oneor more. and preferably two, coiled springs G, which bear at their outer ends against the shoulders or ends b of the spring'chamber or recess B and at their inner ends engage the member or pro'ectionf of the roller spider or frame F, an thus cause said frame or spider to be restored to its central position'when the top or cap plate A is relieved from. load, and this the cap or top plate A. The upright sides roller frame or spider F thus causes the rollchamber to receive the rollers D, which are The roller frame or spider F is preferably too ers D and cap-plate A to be also restored to their central position.
If desired, followers or bearing-disks K may be interposed between the inner ends of the springs G and the spring-bearing member f 3 of the spider F.
I claim 1. In a roller side bearing for railway-cars, the combination of the cap or top plate and the bottom or-base plate having interengaging guidesor flanges to permit thecap or top plate to reciprocatein respect to the bottom or base plate, rollers interposed between saidplates furnished with short shafts at each end, a movable .roller frame or spider having slotted seats or bearings to receive the shafts of the rollers and provided With a projecting spring-engaging member, said bot,-
tom or base plate being provided with a spring-receiving chamber or recess, and a spring tllelfll'r acting upon said spring-engaging member of said roller spider or frame, said rollers and said top and" bottom plates being provided with interengaging teeth.- like devices, substantially as specified.
2. In a roller side bearing for railwaycars, the combination with top and bottom plates,.
short projecting shafts at each end, a roller frame or spider having seats or bearings engaging the shafts of the rollers and provided 'with a projecting member to engage the springs and a pair of springs in the springreceiving chamber or recess ofthe bottom plate, substantially as specified.
