CAR-TRUCK.

Specification of Letters Patent.

Application filed September 11, 1913.

iiatentedNov.it ,1913 Serial No. 789,331.

To all whom it may coaccm Be it known that I, l/VILLIAM F. Kinsnp, J12, a citizen of the United States, and rose dent of Altoona, county of Blair, State of Pennsylvania, have invented certain new and useful Improvements in Caulruchs, of which the following is a specification.

This invention relates to car trucks and more particularly to certain improvements whereby the wear of the wheels may be compensated for to maintain the car body at a substantially uniform height above the ail.

In prior constructions it has been customary to have a 11011-t1lj11$ttbl0 connection between the journal box and the car truck and therefore the truck frame has been gradually lowered as the wheels were or became smaller in diameter and the car body, together with the couplers, would be likewise lowered and as a result couplers on adjoining ears have been considerably out of alinement. This is an undesirable condition in railroad practice and it has been the object of my invention to overcome this condition by providing means for maintaining the truck frame at a substantially uniform elevation above the rail as the diameter of the wheel decreased on account of wear.

The invention is illustrated in the accompanying drawings, in which,

Figure 1 is a fragmentary side elevation of a truck frame and wheel; Fig. 2 is a section on the line 2-2 of Fig. l with the wheel shown in elevation; Figs. 3, t and are sections on the lines A-B of Fig. 1 and showing different arrangements of the shims for adjusting the position of the j ournal box with relation to the truck frame.

Referring to the drawings, 10 indicates a truck wheel which is mounted on the axle 11, the axle being provided with the journal 12 which carries a journal box 13. The journal box 13 is arranged between the end portions of the frame members 1 1 and 15 and as shown in the drawings the journal box is of less depth than the space between the frame members 141- and 15 and the clearance space between the journal box and. the rame members is filled by means of shims.

In Figs. 1 and 3 I have illustrated two shims 16 and 17 arranged between the lower side of the journal box and the lower frame member 15. This is the arrangement of the parts when the wheel 10 is new. In

actual practice I have made the shims 16 and 17 one-half an inch thick and the car wheel has a permissible reduction in diameter of three inches before it must be discarded. When the car wheel has worn off to such an extent that its diameter is reduced one inch or a reduction of one-half an inch in the radius of the wheel, the truck frame will be one-hall. an inch nearer the rail and in order to restore the frame to its original elevatitm above the rail, one of the shims 16 or 17 is transferred to the top of the journal box 13, as shown in Fig. 1. W hen the wheel wears down another inch in diameter the truck frame is again restored to its original height above the rail by changing the second shim from the bottom to the top of the journal box, as shown in Fig. 5.

.Vith the parts shown in Fig. 5 the wheel is allowed to wear down another inch in diameter so that the total reduction in diameter will amount to three inches. The wheel is then discarded.

It will be obvious, from the foregoing, that by my improved construction it is possible to maintain the truck frame and the car body at a substantially uniform elevation above the rail, with a maximum variation of one-half an inch where one-half inch shims are employed. If desired four shims, each one-quarter inch in thickness, may be employed in place of the two one half inch shims which have been indicated on the drawings and in this way the maximum variation in the elevation of the truck frame will not exceed onc-quarter of an inch.

In Fig. 1 it will be observed that the shims 16 and 17 are slightly curved at one end so as to lit the radius at 18 in the truck frame.

Having described my invention what I claim and desire to secure by Letters-Patent is,

1. In a car truck, the combination with the side frame having spaced members be tween which the journal box is secured, of a journal box of less depth than the space between said members, and a shim adapted to fit the top or bottom of the journal box and till the space between the box and the frame, whereby the wear of the truck wheel may be compensated for by changing the shim from one side of the journal box to the other.

2. In a car truck, the combination with the side frame having spaced members bepensated for by changing the shims from tween which the journal box is secured, of a one side of the journal box to the other. 10 journal box of less depth than the space be- In testimony whereof I afi ix mysignature tween said members, and a plurality of in presence of two Witnesses.
