RAILWAY TRUCK Filed June 24, 1925 2 Shoots-Sheet 2 Patented Dec. 23, 1930- UNITED STATES PATENT OFFICE CHARLES P. NOSER, OF ROCHESTER, NEW YORK, ASSIGNOR TO THE SYMINGTON COM- PANY, OF NEW YORK, N. Y., A CORPORATION OF MARYLAND RAILWAY TRUCK Application filed June 24,

This invention relates to trucks and, more particularly, to railway car trucks having roller bearings with provision for allowing angling of the journal box containing said bearings with respect to the supporting frame. 1

The principal object of my invention, generally considered, is the provision of a car truck having side frames between the upper and lower end extensions of which are positioned journal boxes which are preferably of the roller bearing type, said journal boxes being connected to said side frame extensions and so formed that the desired amount of angling with respect thereto as well as vertical movement therebetween is permitted whereby the tendency to unevenly load the axlesand roller bearings is obviated.

An object of my invention is the provision of a car truck, the side frames of which have upper and lower end extensions with journal boxes positioned between said extensions and pedestal means positioned on either side of each journal box and spacing said extensions to allow clearance between the same and the box, through bolts being preferably provided joining the extensions and pedestal means, said box being formed with flanges or guides embracing or cooperating with said pedestal means, sufficient clearance, however, being provided to allow relative motion of the box with respect thereto. L Another object of my invention is the provision of a car truck, preferably having roller bearing journal boxes connected at the ends of the side frames thereof between pedestal means, said means being suflicientlylong to space the upper and lower side frame members a sufficient-distance for providing the desired amount of clearance between the bottom of the journal box and the corresponding tie member to provide a flexible connection between said box and frame.

A further object of my invention is the provision in a truck of the class under consideration of journal box bolts extending between the end portions of the side frame and properly supporting pedestal pieces therebetween, the corresponding journal box being positioned between said pedestal pieces REISSUED and bolts and formed with guides engaging 1926. Serial 1104118389.

said pedestal pieces, the spacing between the end portions of the frame being such that vertical movement of the box on the pedestal pieces is permitted, said pedestal pieces being alternatively formed with rounded portions to permit angling of the box in a horizontal plane and the box being preferably crowned on its upper surface to permit angling thereof in a vertical plane.

Other objects and advantages of the invention relating to the particular arrange- 'ment and combination of the various parts will become apparent as the description proceeds.

Referring to the drawings illustrating my invention, the scope whereof is defined by the appended claims:

Figure 1 is a side elevation of a portion of a railway car truck shown partly in longitudinal vertical section centrally of one of the side frames thereof.

Figure 2 is a transverse vertical section on the line 2-.2 of Figure 1 looking in the direction of the arrows.

Figure 3 is a fragmentary horizontal sectional view on the line 3-3 of Figure 1 looking in the direction of the arrows.

Figure 4 is a fragmentary sectional'view corresponding substantially to Figure 3 but showing a modification of my invention.

Referring to the drawings in detail, like parts being designated by like reference characters and first considering the embodiment of my invention illustrated in Figures 1, 2 and 3, one end of a car side frame is illustrated although I do not wish to be limited to such a showing as the principles of my invention may be embodied in other forms of trucks than here illustrated. Although a side frame 1 of the arch bar type having a compression member 2, a tension member 3 and a tie member 4 is illustrated, I do not wish to berestricted to such a showing as my invention may be embodied in a side frame of other construction than that shown.

The substantially horizontal overlapping end extensions 5 and 6 of the compression and tension members 2 and 3 of the side frame are preferably spaced from the corresponding extension 7 of the tie member 4 by means of a plurality of pedestal members or means 8 and 9, respectively, said pedesnuts 16 are being tightened thereon, lock washers 17 being advantageously used as indicated. The pedestal means 8 and 9 are preferably bifurcated at their ends to form flange portions 18 extending around the adjacent frame member for holding the pedestal means square with respect thereto. The inner and if desired both pedestal means may advantageously be formed with strengthening means such as the rib or flange portion 19, shown most clearly in Figure 3.

The journal box 10 is preferably positioned between the end extensions of the side frame and the pedestal means 8 and 9, as shown, the upper surface or roof of said box being preferably crowned as indicated at 20 to allow angling between said box and frame in an upright or vertical plane. The sides of the journal box adjacent the pedestal means 8 and 9 are preferably formed with guiding portions or ,flanges 21 extending on either side of the'adjacent portions of the pedestal means 8 and 9 with suflicient clearance for allowing a slightamount of angling in a horizontal plane. A greater amount of angling in such a plane is satisfactorily pro vided for, as shown in the modification illustrated inFigure 4 in which modification the pedestal means 9*, as well as the corresponding pedestal means on the opposite side of the journal box, is crowned or curved where it engages the guiding portionof the journal box 10, said guiding portion being preferably formed of a corresponding curvature with suflicient clearance between the same and the flange or lip portions 21 thereon. Except for this change, the second modification maybe the same as illustrated in Figuresl, 2 and 3, it being understood that the pedestal pieces of either modification may be alternativelv formed with or without strengthening flanges or ribs 19.

Positioned within the journal box in accordance with usual practice with roller hearing journal boxes is a bushing or roller bearing raceway 22 and inwardly spaced from said bushing 22 is another bushing 23 surrounding the journal 24 and between said bushings are roller means 25 which may be of standard construction. The details shown for holding the bushing 23 on the journal may be of standard construction not necessitating further description and the usual form of grease grooves 26 may be provided, if desired. The journal box is preferably closed at its outer end by means of a cover or lid -27 preferably connected thereto by means of cap bolts 28 preferably formed with any desired type of locking means 29. A gasket 30 of the usual character may be provided between the lid 27 and journal box 10 to provide a liquid tight oil or grease compartment 31. A plug 32 may be provided for permitting access to the compartment 31 for inserting the desired lubricant therein;

A thrust bearing 33 may be provided on the inside of the lid 27, saidbearing being held in place in the present instance by means of a cap bolt 34 provided with locking washer 35. For lubricating the thrust bearing 33, an oil feeding wick or other means 36 may be provided, held in place as shown particularly in Figure 2 by means of a screw or other connecting means 37.

It will be apparent that by virtue of the aforedescribed construction, a connection between a journal which is preferably of the roller bearing type and an associated side frame is provided allowing a limited amount of vertical movement therebetween and.an-.

gling in all directions thereby obviating the tendency to unevenly load the axle and roller hearing when the truck is rounding a curve. Such flexlbil'lty 1s more necessary in a roller bearing box than with the usual design in which a brass is applied to the top of the axle because the axle in this case is completely surrounded by the bearin and housing and it is not possible w enthe truck is thrown out of square for the axle to float comparatively free within the box. By using through journal box bolts instead of short b'olts, top and bottom, the connection between the frame, pedestals and journal boxes is facilitated and the connecting nuts are more readily applied and kept tight.
