COLUMN OF RAILWAY-CAR TRUCKS;

Specification of Letters Patent. Patgntefl De 19 1916 Application filed February 19, 1914. Serial no. 819,746.

have invented certain new and useful Im- 1 provements in the Columns of Railway-Car Trucks; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates particularly to the portion of a truck including arch-bars and columns separating such arch-bars and forming therewith the side frames of the truck; and it has for its object to provide a column and a connection therebetween and the archbars by which the latter may be detached and removed with facility; and a further object is to simplify the support of the upper end of the brake-hanger and at the same time facilitate the adjustment thereof and exchange therewith of other hangers in case of repairs, or for other reasons.

The invention may be said briefly to consist of a column having a strap extending from one side to the other at the top of the to present an inclosed space or opening of suflicient width for the upper arch-bar, and of sufficient depth to accommodate this bar and the head of a r'vet or other means for connection to the overlying portion of the strap; another feature consists of the column being a casting having as integral parts, that isto say cast in one piece, the strap above mentioned, at its lower end the lateral extension or base-plate adapted to receive the lower archbar, and in addition to this base-plate a pair of wings for connection between the base of the column and other parts of the truck frame.

Another feature consists of an arm formed integrally with the column and having a pair of rigid jaws between which a brakehanger may be suspended.

For full comprehension, however, of my invention reference must be had to the accompanying drawings forming a part of this specification in-which similar reference characters indicate the same parts, and wherein:

Figure 1 is an elevation of the side frame of a truck constructed according to my in vention; Fig. 2 is a transverse vertical sectional view taken on line A B Fig. 1; Figs. 3 and 4 are detail elevations of the column removed, the views being taken at right angles to each other; Fig. 5 is a plan view thereof; Fig. 6 is a horizontal sectional view taken on line C D Fig. 4; and Fig. 7 is a modified construction of the column.

In the usual construction of trucks of this particular type the columns I) are connected to the arch-bars c and (Z to form the side frames by bolts extending completely through the columns and arch-bars and in a order to remove either arch-barit has been necessary to dismemberthe structure. According to my invention this is obviated by casting the column with an opening 6 in its upper end, the upper wall of which is formed by a strap 7' by which the ends of the opening are also formed, this portion of the casting being strengthened by ribs 9 extending from one side of the upper end of the column upwardly over such upper end and down the opposite side where they are extended laterally and merged in an arm 3' curved inwardly relatively to the truck and has its end in the form of upwardly inclined jaws 71: adapted to accommodate the usual brake-hanger m which is held rotatably in place by a split cotter pin a or other suitable means. The main length of this column is of substantial channel cross-section, the flanges o of which are offset as at p and form longitudinal strengthening ribs and at the same time act as a guide for the bolster and keeps it in linewhile the lower end thereof is cast with a base plate 7" and wings s. This base plate is upwardly chambered as at w when being cast for the purpose of accommodating the lower arch-bar which is secured therein by a rivet t or other suitable means. The column thus constructed has the advantage of being integral throughout including the strap and base plate and this fact enables its main length to be substantially in the same vertical plane and the vertical plane of the archbars, thus enabling sufficient accommodation to be afforded for threading the upper arch-bar through the opening.

' An opening for the insertion of the archbar may be provided in the upper end of the column by casting such column with an opening extending completely through one side and the top of the column having an enlargement of the strengthening rib g to coinpensate, for the side portion cut away.

What I claim is as follows: 1. In a railway car truck of the type having upper and lower arch bars; an integral column for spreading the arch bars, said column consisting of a member of box-like form having a comparatively large opening near its upper end to permit the passage therethrough of the upper arch bar; means for securing the upper arch bar to the column. and means independently of said just-mentioned means for securing the lower arch bar to the column and continuous strengthening ribs extending up one side and across the top of the column.

2. In a railway car truck of the type having upper and lower arch bars, an integral column for spreading the arch bars, said column consisting of a member of b0x-like form having a comparatively large-opening near its upper end to permit the passage therethrough of the upper arch bar and having a recess in its opposite endfor the purpose of straddling the lower arch bar, and

continuous strengthening ribs extending up one side and across the top of the column.

3. In a railway car truck of the type having upper and lower arch-bars, and an integral column for spreading the arch-bars such column consisting of a casting having two Witnesses.
