CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 626,552, dated June 6, 1899. Application filed December 27, 1898. Serial No- 700,455. (No model.)

To all whom may concern.-

Be it known that I, GEORGE O. MURRAY, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Car-Trucks, of which the'following is a full,-clear, and exact description, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to car-trucks; and it consists of the novel construction, combination, and arrangement of parts hereinafter described and claimed.

Figure 1 is a side elevation of myimproved car truck. Fig. 2 is a plan view thereof. Fig. 3 is a view in perspective of one of the side frames of my improved car-truck. Fig. 4 is a view in perspective of the mating plates which form the housing for the upper end of one of the springs of the truck. Fig. 5 is a view in perspective of a pair of mating journal-box guides. Fig. 6 is a view in perspective of one of the wearing-plates made use of in carrying out myinvention. Fig. 7 is ahorizontal sectional view taken approximately on the line 7 7 of Fig. 3. Fig.8 is a horizontal sectional view taken approximately on the line 8 S of Fig. 3 and looking upwardly. Fig. 9 is a View in perspective of a bearing-plate such as is located in the spring-housings.

In the construction of my improved cartruck I make use of a bolster or transom 1, which is preferably constructed of a pair of I-beams, to the ends of which are riveted or bolted the side frames of the truck. Eachof these side frames comprises an I-beam 2, the center of which is depressed, together with the lower member 3, which is preferably a T-bar having its center arched, or said lower member may be an I-beam. As heretofore stated, the ends of the bolster 1 are secured to. the side frames by rivets or bolts, and to further strengthen the frame of the truck so constructed clips at are riveted to the top of the T-bar 3 and to the flanges at the ends of the I-beams forming the transom or bolster 1.

Located upon top of the ends of the bolster or transom are the plates 5, on which the side bearings of the truck operate, and located at the center of the bolster or transom is a kingpin guide or seat 6, the same being securely riveted or bolted to the webs of the I-beams forming the bolster or transom.

Formed in the flanges of the T-bar 3, adjacent its ends, are the pairs of rectangular notches 7, and formed in the lower flanges of the I-beam 2, in alinement with said pairs of notches 7, are the pairs of notches 8, all of these notches extending approximately halfway through the width of the flange, and the balance of the flanges between the pairs of notches Sin the I-beam 2 is removed, the purpose of which will be presently set forth. Seated upon the ends of the I-beams 2, one on each side thereof, are the plates 9, the same being of the same size and construction and equal in width to the web of said I-beam, with the outer faces of which plates are formed integral the semicircular casings 10, there being the vertically-arranged flanges 11 formed integral with the outer faces of the ends of said plates. When these plates are correctly positioned upon the web of the I-beam, the ends of the casings 1O coincide with the inner ends of the pair of notches 8, thus forming the circular housings for the upper ends of the springs.

The journal-box guides, (seen in Fig. 5,) a pair of which have their upper ends seated upon each end of the plates 9,comprise the vertical plates 12, in the upper ends of which plates are formed the oppositely-arranged notches 13,Which pass into the pairs of notches 8 in the lower flange of the I-beam 2, which notches also engage upon the portions of the which extend between the material of said plates 12 surrounding the notches 13 and 14. The lower ends of the pair of platesl2 that is located adjacent the outer ends of the side frame are extended inwardly toward the center of said frame, while the lower ends of the ICC inner pair of plates 12 are extended outwardly to meet the extended inner ends of the outer pair of plates. The ends of the inner pair of vertical plates 12 are held together and to the inner ends of the plates'9 andto the webs of the I-beam 2 and T-bar 3 by the rivets 16, said plates 9 being held to the web of the I-beam 2 by the rivets 17. The outer pair of plates v12 are held to the ends of the plates 9 and to the web of theT -bar 3 bythe bolts 18, the nuts for said bolts being upon the inside faces of the-side frames.

Located within the spring-housings, composed of the mating casings 10, is a disk 19, the same being provided'on its under side with'a lug 20, said disk being held within said housing by the rivets 21, which pass through the top of the casings 10.

The journal-boxes 22 used in connection with my improved truck are of the ordinary construction and provided in their'sides with the vertically-arranged groove 23, and formed integral with the top of each box is a circular lug 24, the usual helical coil-springs 25 being interposed between the journal-box and the plate 19 in the top of the spring-housing, the ends of said spring being seated upon the circular lugs 20 and 24.

The wearing-plates 26 engage in the vertical groove 23, formed in the sides of the journal-boxes, said wearing-plates being provided with integral rearwardly-projecting ribs 2'7, which are located between the pairs of journal-box guides.

By my improved construction a very strong, simple, and compact car-truck is produced, and whenever desired the bolts 18 at either or both ends of the truck may be quickly removed in order to take out the axle, wheels, and journal-boxes.

By making use of I-beams and T- bars for the side frames the construction of the truck is greatly simplified and cheapened, inasmuch as no large castings or specially-formed parts are required, and the entire truck may be as sembled in any ordinary car-repair shop.

I claim 1. In a car-truck, a bolster, a pair of I- beams having depressed centers and a pair of T-bars having arched centers, a pair of which I-beams and T-bars are rigidly secured to the ends of the bolster and to each other, substantially as specified.
