Application tiled March 27, 1911. Serial o. 617,242.

To all whom it may concern:

Be it known that l, ARNOLD A. WEIcnL, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Antifriction-Bearings; and I do hereby declare that the fol lowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings','andto the letters of reference marked thereon, which form a pai-tof this specification.

This invention relates to antifriction bearings, and more particularly to what are known as side bearings for use on railroad cars.

The invention consists of the matters'hereinafter described, 4and. more particularly pointed out in the appended claims.

In the drawings :-Figure l is a view representing a longitudinal, central section through a side .hearing made in accordance with my invention.- Fig. 2 is a bottom plan 'View of the same.` Fig. 3 is an end elevation.

Fig. 4 is a transverse section through the bearing onthe line 4-4 .of Fig. 1. Fig. 5 isV a transverse section through the bearing on line 5-5 of Fig. 1. Fig. 6 is a top plan View of the bearing. Fig. 7 is a transverse section bthrough the antifriction rollerand the frame supporting the same showing a slightly modified form of the construction.

Referring now more particularly in detail 5 L to the drawings, 10 re resents a casing by means of which the antlfriction device is secured to the car bolster, said casing inclosing an antifriction roller 11 which is adapted to transmit load in a familiar manner from a hearing or wear-plate supported in the casing to be more particularly referred to later, and a hearing or wear-plate 'provided on the truck holster. The casing 10 is of oblong, rectangular form and is provided at its four corners with ears 12 located on a level withits top surface land hv means pf which it is adapted to be secured to the car bolster by bolts (not shown) which pass through, apertures 12EL in said ears. The said casing comprises side members 13, 13 and end members 14, 14. Thelatter are pro-` vided 'on their inner faces with transverselyl extending lugs or shoulders 15, 15 on whic rests a bearing or'wear-plate' 16, said wearcasing 10; Said ribs or flanges 18, 18, of the filler block 17, depend below the lower face of the wear-plate 16 and provide thrust shoulders to take up the lateral thrust of the antifriction roller 1 1. y

The antifriction roller 11 is sus ended from the frame or casing 10 by the ollowing mechanism: 19 indicates a roller frame comprising laterally spaced side members 20, 20, and transverse webs 2l, 21 which are located onein front and one at the rear of the roller 11. The side members 20, 2O of said roller bearing 'frame are connected at their ends by transverse rods 22, 22 which extend through vertically elongated apertures 23, 23 formed in sleeves 24, 24 which are each made integral with a pair of upright links 25, 25. 1Said links and sleeves together constitute swinging suspension members 24a which conne'ctthe roller frame with the casing and suspend the said roller frame therefrom. At the upper ends of said links 25, 25 are formed vertically elongated eyes 26, 26 by means of which sald links are suspended from transverse rods 27, 27 secured to the frame 10.

As shownV in Figs. 1 to 6, inclusive, the antifriction roller 11 is provided with integral trunnions 28, 28 which rest in U-sha ed, upwardly opening sockets 29, 29 formed in the side nim'hers 20, 20 of the roller carrying frame.

The operation of the bearing is as fol lows: lVhen the roller is transmittino' load and'engaged with the bearing or wear-plate 16, the rods 22, 22 are in the highest parts of the apertures through which they extend, and the-links `25 'are each, as a whole, in their -highest position with the rods 27 in the lowest parts of the eyes 26 in said links in which they are located. When the antifriction roller rolls away from the center ,of the casing it carries the roller.bearing weight of the suspension members 24a, 24a comprised by the pairs of links 25, 25 and the associated integral sleeves 24,24 causes them pendulum-like to swing toward a vertical position, thus returning the roller bearing frame to its normal central position and with it the ant-ifriction roller.

In the preferred form of my improved bearing the rods 27 are mounted in the frame so as to be non-rotative, said rods being squared at one end as shown'in Fig. 5. The links 25 are each provided with a detent 26a depending from the upper side of the eye 26and adapted to engage ina notch or opening 27a 'in the rod 27, below said detent. The object of these detents and notches is as follows: After the roller carrying trame, during the transmission of load by the r roller, has moved to one or the other side of the center ofthe frame or casing and when the roller is released and brought back to center by means of the swinging, suspension members 24a, the detents 26a of the links engage in the notches 27a of the rods 27 and lock said suspension members in vertical position. This position is maintained, notwithstanding jars or liolts of the car until l the antitriction roller is raised into engagement with the wear plate 16, when said roller is next brought into place to transmit load from the body bolster to the truck bolster. This prevents la constant swinging movement of the suspension arms when the antifriction member is idle and obviates the resultant wear and rattling of the parts.

In Fig. 7 I have shown a modification of the means by which thegroller is supported in its frame. In this case 11a indicates the roller," and 20a, 20a the side members of its supporting frame. 'The roller 11a has a central bore 30 in which is located a bolt or rivet 31 which extends through suitable apertures 29a, 29El formed in the side members of the'frame, said bolt being held in place on one sideby a head 32 and on the other by a nut 33. In this case, the roller "instead of having'integral trunnions which have bearing in the side members of the frame is journaled on a bolt which rigidly connects the 'side members of the frame. Manifestly, the bolt might be replaced by a rivet.

I claim as my invention 1. In a'n antifriction bearing, in combination with an antifriction member, and a swinging suspension member adapted for supporting said antifriction member, means for locking said swinging suspension member ina predetermined position when said antifriction member is not transmitting load.

2. YIn an antifriction bearing, in combination with an'antifriction member, and means for suspending said antifrict-ion member, said suspending means including a link protion when said link is suspended fromgsaid bearing.

3. In an antifriction bearing, in combination with an antifrict-ion member, and means for ,suspending 'said antifriction member,

. said suspending means including a link provided with an eye, and a non-rotative rod extending through said eye, said lin being provided with a depending detent coated in said eye and adapted for engagement with a notch formed in the upper side of said rod below said detent, when said link is suspended from said fdd.'
