' Application filed March 3,1902. Serial No.y 96.403. (No model.)

To all wir/0771, it may concern: p

Beit known that we, FRANCIS G., SUSEMIHL and AUGUSTUS Tonner, citizens of the United States 4of America, residing at'Detroit, in the county of Wayne and State of Michigan,'have invented certain new and useful Improvements in Car Side Bearings, of which the following is a specification, referencebeinghad Vtherein to the accompanying drawings.

This invention relates toY that class of side bearings in which antifriction-rollers are interposed between the truck and lbody bolsters on opposite sides of the center bearing.

The object' of our invention is to make a roller-bearing of simple construction and not liable to get out of order; and to this'end the invention consists of a casing carried by thebody-bolster and inclosing al series of Vdisconnected roller-trucks guided upon a track within the casing and coperating with a bearing on the truck-bolster' to forman anti'- friction side bearing, all as more fully hereinafter described, and shown in the accompanying drawings, in whichi Figure l is a side elevation of the bearing 'with thefrontwall of the casing broken away to show the interior of the casing. Fig'.- 2 is a top plan of the bearing; Fig. 3, across-section of the bearing. Fig. 4 is a detached plan Vof one of the roller-trucks, vand Fig.v 5V is an en'd elevation ofrFig. 4.

Aand B represent the outer ends of a bodybolster and a truck-bolster, respectively, between which our improved side bearingis interposed, thebolsters being, as usual, provided with a center bearing.- (Not shown.) C is the casing', secured in any suitable manner to the under side of the body-bolster, and D represents a series of roller-trucksinclosed in said casing free to travel. Each roller-truck consists of a pair of tapering rollers a`,for1ned with journals b, and of la rigid frame coinposed oftwo side bars c c', formed with bearings d, in which the .rollers are removably journaled, and of a cross-bar e, connecting the side bars between the rollers. The side bars c c.. are rounded off at the ends, and the journals l) of 4 the rollers project beyond the side bars of the truck-frame.r The side bars are also provided with hoods'jwhich project over the top yportions 'of the projecting ends of the rollers, but leave the lower portions exposed. These hoods strengthen the sidev bars. at the bearings and at the saine time form stops to prevent the endwise movement of the roller in the truck-frame. truck is adapted to form anindependent traveling unit, and the series of trucks together form an endless'train free to travel within the casing around a central core g formed Each rollerthereinand adapted to support a 'plurality core at a distance apart equal to the length of the bearing-face of the rollers and adapted to guide the roller and mediately `the trucks in a path concentric with the center bearing. The casing is open on top and bottom and may be cast in one piece, with the exception of forming the bearing-face for the active rollers ofaseparate steelA plate j. The

sides of the casing at their lower edges are formed or provided with inwardly-proj ectin g retaining-danges i, which prevent the rollertrucksfrom falling out in. case the bolster B shouldbe withdrawn. These retaining-flanges,

however, continue upward upon the sides'of the casing in the path of the roller-trucks,

and from being vmere r'etaining-iianges they Vbecome bearing-flanges '11', upon which the projecting ends of the journalsof the rollers y are adapted to travel in rolling contact therewith in passing around the ends of the core g, the hoods being suitably cut away to pe mit this travel;v The anges fz are continued upward sui'i'ciently to guide the rollers till they can travel upon the top portion 'of the core, and they are then-stopped off, so

as to form a clear and unobstructed entrance into the top of the casing, through which the trucks maybe inserted into or removed from the casing when the casing is taken oEEI The l flanges e" inl connection with the attened portions of the core thus forni the track on which the rollers travel whenever alrelative movement between lthe holsters takes place,

, and in whatever direction the movement takes ment takes place' and in such manner that as soon as each roller is relievedof the load it commences to travel withits journals upon the flanges i', owing-.to the tendency of the trucks to 'push each other outwardly in passingaround 1the ends of the core. In doing so the rollersy are .caused to revolve in a re- `verse directon upon their axis till gravity causes the trucks to drop on top of the core. In passing-over the top the rollers travel upon the core, while the trucks ride upon bearings l, formed between the guide-anges hand the sideof the casing. As the trucks collectively form an endless train in which the individual trucks can havev little or-no independent travel, itis not necessary that thereshouldbe any connection between the trucks. In fact, vwe find it more desirable that the trucks should be independent, as it insures greater freedom in travel by allowing the trucks to slightly separate. It also dispenses with unnecessary parts. However, suitable connections between the trucks may be used without interfering withthe broader featuresv of our invention. The contour and shape of the trnckframe is such that rubhing contact with the casing will be avoided, and the side bars areof such relative lengths that a line drawn through the extreme end. will pass through the center bearing. In-

stead of one cross-bar 'centrally uniting the side bars the side bars may be united by cross-bars near the ends.

It is obvious that our improved beat-in g in.-

stead of being carried by the body-bolster may beA carried upon .the truck-bolster, and any modification with this end in view we deem to be within the scope of our invention. The advantage of roller-bearings in which the rollers travel in a continuous path over those in which the rollers are stationary or travel in the are of a circle only is well understood.; but in all construction of the former kind of which we are aware it is possible for the rollers to skew-that is, they get ont of radial alinement with the center bearingand thenk they become inoperative as an anti'- friction ;bearing. In our construction thiscannot occur,as the rollers are rigidly held in alinement by being journaled in rigid truckframes, two or more. It will also beseen that our construction is simple and the rollers are adapted to'travel with a minimum of friction.
