1929. Divided and this application filed Gctober 1, 1929.

This invention relates to structures for 10- comotives and more particularly to a novel combination of side frame members, truck center plate and pin, bumper bracket, brake cylinder brackets, crosshead guide brackets, working cylinders, distribution valve chests and/or cylinder saddles, and is a division of my copending application Serial No. 265,888, filed March 28, 1928,11ow Patent No. 1,731,511, of October 15, 1929. An object of the invention is to provide a structure of such type, which will be strong, rigid, and simple; which will effect a substantial economy in the cost of manufacture; which will effect a substantial reduction in the number of separately form-ed connected members; and which will insure accurate alignment of the side frame members, by permitting the necessary boring and slotting thereof to be performed in pairs.

Another object of the invention is to pro vide a crosstie member adapted to rigidly couple together a pair of side frame mem bers, which crosstie member may be employed to support a cylinder saddle and may have incorporated with it a center pin, or a bumper bracket.

Other objects of the invention will hereinafter readily appear.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure 1 is an isometric view of a fabricated structure embodying the invention the right hand side frame member being shown removed; Fig. 2. an isometric view of the removed side frame member; Fig. 3, a vertical transverse section taken on the line llllll of Fig. 1; Fig. 4:, a vertical longitudinal section taken on the line lVlV of Fig. 1; Fig. 5, a vertical, transverse section taken on the line VV of Fig. l; and Fig. 6, a plan view, the lower half being in section.

In the practice of the invention, referring descriptively to the specific embodiment thereof which has been selected for exemplificatien herein, the frame comprises two counterpart side frame members, 10, each comprising a main side frame member 11, and front side frame member 12. Pref- Serial No. 396,425.

erably the main and the front side frame members are formed together as an integral casting, but itis within the contemplation of the invention to form them separately. They are also preferably, but not necessarily made of hollow or box cross-section.

Each front side frame member comprises inner and outer vertical side walls 12a and 12?); top and bottom horizontal walls. and 12d, connectin the side walls; transverse walls, connecting the side walls and providing sockets, or mortises 12h and 122', for the reception of cross tie tenons; and a vertical longitudinal flange 12 extending above the top wall 120, and constituting a bracket for the attachment of a brake cylinder. The side walls 12a and 125 are provided with openings in register with the sockets 12h and 122', and the top wall 120 is provided with a transverse depression or pocket 12% adapted to receive a cylinder saddle. Suitable bolt holes 1% are provided in the side walls 12a and 12?) for the reception of bolts for fastening the cylinder to the frame member.

A cross-head guide bracket 11a, is preferably, though not necessarily, formed integrally with, and projects laterally from, each main side frame member 10.

The front side frame members 12. are rigidly secured together by a truck center plate cross tie member 13. and a bumper beam bracket cross tie member 14. A The truck center plate and pin member 13. 1s disposed between and at the saddle pocket portion of the front side frame members. is preferably, though not necessarily. formed as an integral casting, and compi'ises horizontal top and bottom walls 13a and 137): a central vertical tubular wall 130, connect ing the top and bottom walls and projecting below the bottom wall to form a center-pin 13d; vertical transverse end walls 136. obnnecting the top and bottom walls vertical longitudinal side walls 13;", connecting the top, bottom, and end walls; vertical longitudinal bracing walls 139, connecting the top. bottom, and tubular walls; vertical trans verse bracing walls 13h, connecting the top,

bottom, tubular walls and side walls; and

tubular tenons or dowels 135, one projecting laterally from, and intermediate the length of, each side wall, the tenons being adapted to be force or press fitted into the sockets 12h, of the front side frame members, and welded to the walls thereof. The side walls 13;". are provided with boltholes 13;; in line with holes 121, for bolting the casting to the front side frame members, and the top wall 18% is provided with openings 13X: to permit access to certain of the bolts.

The bumper beam lr; cltet cross tie member 1+. is disposed between and at the forward end of the front side frame members; preferably though not necessarily. formed as an integral casting; and comprises, vertical longitudinal side walls 14a. vertical front and rear walls l i-Z) and l lo. connecting the side walls, a horizontal wall lei-(Z, connecting the side, front, and rear walls, and tuljiular tenons or dowels 140, one project ing laterally from, and intermediate the length of. each side wall. each tenon being adapted to be force or p 'ess fitted into one of the sockets 125, of the front side frame members and welded to the walls thereof. The front wall 14]) is adapted to serve as a bracket for the attachment of a bumper beam. It is within the contemplation of the invention to form the bumper beam integrally with the bumper cross tie member.

Supported in the pockets 12b of the front side frame members, are two counterpart integral castings 16, each comprisii'ifr a half saddle 16, a cylinder 16?), and a distriliiution alvo chest 160. It is within the contemplation of the invention to form the saddle. the cylinders. and the distribution valve chests separately. or to combine them together, or with the front side frame members in any of the ways heretofore known.

\Vhile the l. nnper beam cross tie and the center pin cross tie have been shown as separately formed it is within the contemplation of the invention to combine them in an integral casting.

While one of the preferred forms of construction has been shown. it is obvious that many variations in procedure. form. a rran gement. and construction of the parts can he made, and the invention is not therefore limited to the particular embodiment disclosed, but includes such. changes and modifications as come within the spirit and scope of the invention as set forth in the appended claims.
