UNITE@ STATE PATENT @FFIGEO JOHN A. LAMONT, OF C'rIltiil\TITIi|` CITY, ILLINOIS, ASSIGNOR '10-AMERICAN STEEL FOUNDRIES, OF NEW YORK, N. Y., A CORPORATION 0F NEW JERSEY.
SWING-TRUCK.
T0 al? ivlzom. it concern:
Be it known that I, JOHN A. LAMONT, a citizen of the United States, and resident of Granite City, in the county of Madison and f and has particular reference to a novel swing or lateral motion truck.
Many railroads prefer to utilize a car truck in which the bolster shall be adapted for lateral movement with relation to .the side frames of the truck. This result is secured by the utilization of many different forms of mechanical devices and the present l construction is intended asan improvement thereon.
One of the objects of the present invention is to provide for maximum lspring capacity and for the distribution of the load carried by the springs over a greater area and to bring the'support for the springs nearer to the axles of the truck', whereby less strength and rigidity is required of the side frames..
bolster is permitted and in which the size and capacity of the springs is not limited by the usual space provided between the columns of the truck.
The invention will be more readily under-1 side frame having columns, a bail mounted stood by reference to the accompanying "drawings, wherein- Figure 1 is a side elevation of a car truck constructed in accordance with my invention; Fig. 2 is a bottom plan view thereof,
and Fig. 3 is a section on the line 3 3 of Fig. 1.
Referring more particularly to the drawings, it will be seen that the side frame contemplated by me is an integral structure comprising compression member 10,I tension member 11, columns or struts 12l and pedestal jaws 13, betweenwhich a journal box 14 is adapted to be received and held. Between the two struts 12 an opening is provided i within which the end 15 of a bolster is adapted to project. rI`he bolster on its lower surface near the ends is provided with an earxit, to which is secured a shoe 17 @n Specification o f Letters Patent.

the lower surface of the shoe I provide marglnal flanges 18. rlihe upper surface of the shoe is cui-ved to correspond to the curvature of the ear 16, and rotary movement is possible between the shoe and the ear. The shoe 17 rests upon and the flanges 18 engage the lower portion 19 of. a llei-shaped support or bail 20. vApertures are provided in the lupper ends of the bai-l, and a shaft 21 ex'- tnds through the apertures and through an elongated opening 22, shown in dotted lines in Fig. 3, in the columns 12 'of the sideframe.
'Ihe ends of the shaft 21 engage spring caps 23, located outside of the struts, which caps .rest upon springs 24, two series of spring 'being preferably placed beneath each cap.
These springs rest within pockets 25, formed integral with the side frame.
It will be seen that the springs 24: are located considerably nearer to the axles of the truck than has commonly been the practice. Also that the size and capacity of the springs is n'ot limited, due to the increased space within which such springs may be located. Such construction provides for the ready dismantling of the truck without removing bolts or rivets, it merely being necessary to jack up the bolster sufficiently to disengage the bail from the lower portion thereof, whereupon the bolster may be removed longitudinally through the 1opening between the columns. In some cases it may be necessary to remove the shaft 21 to provide suiiicient space for the removal of the bolster.
` I claim: y
1. In a car truck, the combination of a stantially as described.
2. In a car truck, the combination of a ,side frame having a bolster opening, a bail inv said opening, a bolster mounted on said bail, a pivotgfor said bail, said pivot proi `:|ecting through said columns, and springs mounted outside of said columns and providing a bearing for said pivot, substantially as described.
8. In a car truck, the combination of a side frame having columns providing a bolster opening, a bail mounted in said opening, a shaft supporting said bail, the ends of which shaft project through said columns, spring seats provided on said frame outside lll@ -said opening, a
of said columns, springs'mounted on said seats, und spring caps providing bearings for the ends of said shaft, substantially 'as bolster, a shaft acting as a pivot for said 10 buil, springs mounted outside of said coll bail for supporting said l umns, and spring caps .resting on said springs and providing bearings `for said s aft, substantially as described.
Signed at Granite City, Illinois, this 2li day of May, 1915.
