Specification of Letters Patent.
Patented Sept. 1'7, 1907.
Application filed December 17,1906. Serial No. 348,270.
To all whom it may concern:
Be it known that I, HARRY S. HART, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification. i
The object of my invention is to provide a car truck in which the bolster may be attached to the side frame of the truck by means that will permit the use of an integral side frame, or, if a non-integral side frame is used, will permit the removal of the bolster from the side frame without separating the parts of which the latter is formed.
My improved construction embodies means whereby the bolster may be separated from the side frames without disarranging any of the other parts of the truck.
In the drawings-Figure l is a side elevation, partly in section, of a truck equipped with my invention. Fig. 2 is a plan view of the same, also partly in section. Fig. 3 is a side elevation of a truck showing a modified form of my invention. Fig. 4 is a transverse sectional view of the structure shown in Fig. 3. Fig. 5 is a plan view, partly in section, of the modified form.
In Fig. 1 of the drawings, a and I; represent the upper and lower arch bars of an integral side frame, the columns of which are designated (Z. In this form of my invention I provide the bolster e with undercut grooves 9, two of such grooves being located on each side of the bolster. These grooves are separated by a distance equal to the thickness of the side frame. It may not be necessary in all cases to undercut the grooves in the manner shown.
The locking members consist of metal ears f having a base portion corresponding in cross section to the grooves g and a projecting portion of any form adapted to engage the side frame of the truck and hold the bolster against longitudinal movement. In this form of my invention the detachable ears f serve the same function as the usual integral ears upon a form of bolster now in extensive use. The distance between the projecting portions of the detachable ears f is such that while the bolster is held in proper relation to the side frame it is still permitted the necessary vertical movement upon the springs g.
The parts are assembled by inserting the end of the bolster e in the opening in the side frame. At this time of course the detachable ears f are not in place. After the bolster is properly positioned in relation to the side frame, the locking members f are driven into the grooves 9. These members are so proportioned that they will snugly fit the grooves 9 thus insuring them against displacement. When it becomes necessary to separate the bolster and side frame for any purpose, the lockingmembers f are driven endwise until freed from their positions in the grooves g.
In the modified form of my invention illustrated in Figs. 3, 4 and 5 of the drawings, I have shown locking members in the form of pins 70. When such locking pins are used the bolster is provided with openings Z corresponding in form to the cross section of the locking pins. These openings are spaced apart a distance sufiicient to give place for the side frame of the car be tween the locking pins. 1 have shown the locking pins 70 as being cylindrical in form, but it will be understood that any other desired form may be adopted or that the number and size of such pins shown in the drawings may be varied without departing from the scope of my invention. As in the Iorm of my invention above described the parts are assembled before the locking pins are inserted in the bolster. After the bolster is properly positioned, locking pins are driven home, thus preventing longitudinal displacement of the bolster, but permitting it to move vertically upon its springs.
What I do claim is:
1. In a car truck, a side frame, a bolster, recesses in said bolster, and guides having a tight driving fit in said recess.
2. In a car truck, a bolster provided near its end with an undercut groove, and a locking member engaging said groove and the side frame of the truck.
3. In a car truck, a bolster provided near its end with a transverse undercut groove, and a locking member engaging said groove and the side frame of the truck.
4. In a car truck, a side frame, column-guides in said side frame, and column-guide lugs having a tight driving fit in recesses in the bolster, said lugs engaging the opposite sides of the columnguides.
5. In a car truck, a side frame, column-guides in said side frame, a bolster, lugs upon said holster, said lugs being spaced apart and adapted to engage the opposite sides of each of said columirguidcs, the lugs engaging one side of said column-guides being removable independently of the lugs engaging the opposite side.
