lnlllllll Il .T M 5 n R N m6 R N s O E e l M m A nVlm.. -I1 l. o o I. @0E I Patented Oct. 21, 1930 'PATENT OFFICE JAMES G. BLUNT, OF SCHENECTADY, NEW YORK CROSSTIE STRUCTURE EUR Application filed September This invention relates to improvements in cross -tie structures for locomotive side frames, and more particularly to cross-tie structures designed for application between the front ends of the side frame members of a locomotive.

An object of the invention is to provide a cross-tie structure which is economical to manufacture and maintain; which is convenient to install and remove; which is of great durability; which is adapted to firmly and securely connect together the side frameV members, the cylinder saddle, and the bumper beam; and which embodies a novel, rugged,

: and eilicient center pin construction.

Another object of the invention is to provide a cross-tie structure, embodying the advantages indicated, which may be formed as an integral or one piece casting.

ther objects of the invention will hereinafter readily appear.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawing: Figure 1 is a top plan View of a crosstie construction embodying the invention; Fig. 2, a side elevation thereof; Fig. 3, a longitudinal, vertical section on the line III- III of Fig. 1; Fig. 4, a. partial front end view, in elevation; Fig. 5, a partial, rear end View, in elevation; Fig. 6, a vertcal transverse section, taken on the line VI-VI of Fig. 1; Fig. 7, a vertical, transverse section, taken on the line VII*VH of Fig. 1; and, Fig. 8, a partial, horizontal, transverse section taken on the line VIH- VIH of Fig. 2.

In the practice of the invention,.referring descriptively to the specific embodiment thereof which has been selected for exempliiication herein, the cross-tie structure comprises an intermediate, or cylinder saddle supporting portion, A, a front portion, B, eX- tending forwardly of the cylinder saddle por'- tion, and a rear portion, C, extending rearwardly of the cylinder saddle portion.

The structure embodies two substantiallyv parallel vertical side walls, 10, each having front and rear portions, a, and 10b disposed in substantially the same vertical plane and extending respectively throughout the lengths Loociaofrrvn sinn FRAMES e, 1929. serial' No. 390,697.

of the front and rear portions, B and C, and an intermediate portion, 10c, set inwardly of the front and rear portions, at the saddle supporting portion, A, of the cross-tie structure, to provide clearance for the heads of the usual bolts by which cylinder castings are attached to side frame members. Suitable bolt holes, 10, are provided in the front and rear portions of the side walls for bolting the cross tie structure to the side frame members. Each rear portion, 10b, of the side walls is formed at its rear end with a vertical upstanding extension, 10e, to provide additional areafor bolting to side frame members.

yThe rear portions, 10b, of the side walls are tied together by a single transverse web, 11, which has a longitudinal portion, 11a, oined to the tops of the rear portions of the side walls and bellied upwardly therefrom to provide clearance for a truck accessory, and a vertical or upstanding portion, 11b, joined to the front ofthe extensions, 10e.

The intermediate and front portions, l()c and 10, of the side walls are tied together by two vertically spaced webs, 12 and 13, the web, 12, being oined to the tops of such portions, and the web, 13, to the bottoms thereof. The top web, 12, projects laterally beyond the intermediate portion, 10, of each side wall to provide a reinforcing flange, 12a. A portion of 'the sides of both webs, at the forwa rd ends thereof, terminate short of the sine walls, and are joined together by vertical wal ls, 111, which in turn are oined to the front portions of the side walls by horizontal webs, 15d, disposed intermediate their heights. This constructien enables the bolts for fastening the cross-tie structure to the side members cf the frame, te be conveniently applied.

rlhe webs,12 and 13, and the frcnt portions, 10, of the side walls are joined to a transverse vertical bumper flange or bracket, 16.

Vl'he top web, 12, at the cylinder saddle portion cf the cross-tie structure, is formed with four spaced bosses, 17, for the attachment of suitable cylinder saddles. y

To provide for a center pin, the top and the bottom webs, 12 and 13, are each formed with a circular aperture and are connected by a cylindrical wall, 1S, which forms a socket,

it, toi' tin reception et the cilindrica] ci (lle supporting; portion ifoiiiprfiiiigi; veitiiilllv tension, 1920i ii center pin, lll. llitx centri' pin formed with circumferential segmental ianges, 19h, having their top faces formed with bosses, 19, which fit in grooves, 13, in the bottoni 'tace ot the bottom web, 13. Bolts, 19, ias g through the bossed portions of the flange, 19h, ot the center pin, and the bottom Walls of the grooves, 138, in the bot-- tom Web, in cooperation with the cylindrical extension, 19a, ot the center pin and its socket, 18a, serve to irnily attach the center pin to the cross tie structure.

Suitable ribs, 18h, radiating trom the socket Wall, 1S, and connecting` the top and the bottom webs serve to reinforce the structure to eiiiciently withstand the stresses imposed on the center pin.

The bottoni web, 13, is connected at its rear to an upstanding wall, 21, which in turn is connected to the top Web, 12. The Wall, 21, has a bellied portion, 21a, to afford clearance for a truck accessory.

The invention contemplates *forming the entire cross-tie structure, excl .sive ot tlie center pin, as an integral. or one-piece casting; and also termin@l the entire cross-tie structure together with a center pin as an integral or one-piece casting.

.Vhile one ot the preferred forms of construction has been described and shown, it is Obvious that many variations in procedure, and in the torni, arrangement, and construction oit the parts, may be resorted to, and the invention, therefore, is not limited to the particular embodiment disclosed, but inclndes such changes and modifications come Within the spirit and scope of the invention as set forth in the appended claims.
