GUIDE-BEARER QROSSTIE FOB LOCOMOTIVES.

Application filed December 18, 1926.

The object of my invention is to so design a guide bearer cross-tie that it will not only brace the frame of the locomotive but will support the guides for the cross-heads and a rock-shaft of the valve mechanism.

In the drawings, the guide bearer not only carries the side guides but also the central guides, as the construction shown is adapted to a three-cylinder locomotive.

In the accompanying drawings Fig. 1 is a perspective View of my improved guide bearer cross-tie for a locomotive;

Fig. 2 is a side View;

Fig. 3 is a plan view; and

Fig. 1 is an end view.

The guide bearer cross-tie 1 is made in a single casting, preferably of steel, and has a foot portion 2 at each side which rests upon a side frame of the locomotive, as shown in Fig. 2.

Depending from each foot section is a deep inner flange 3, which is secured to the inner side of a side frame and a rib at which extends on the outer side of the side frame.

Each foot section is of considerable length so that the cross-tie is rigidly supported on the side frame. Bolts extend through the feet 2 as well as through the flanges 3. Strengthening ribs 5 extend from the ends of the feet to the body of the cross-tie as shown in Fig. 1.

The body portion 6 is that portion of the cross-tie between the ribs of the foot section, and consists of a web 7 having an upper flange 8 and a lower wide flange 9, shaped as shown in Figs. 1 and 3. On one side of the cross-tie the lower flange is curved, while that portion of the flange on the opposite side of the cross-tie is angular.

The centre of the lower flange 9 of the body portion is flat, as at 15, and finished to receive the guide a for the central cross-head.

At each end of the body portion 6 of the cross-tie is an extension 10 in the form of a bracket, the lower portion 11 being curved Serial No. 155,689.

and enlarged at the end to form a plate 12, to which a side cross-head guide I) can be se cured by bolts which pass through openings in the plate shown in Fig. 3.

One end bracket is heavier than the other and has two flat surfaces 13 to which are secured the bearing brackets for a rock-shaft 0 of the valve mechanism.

Each bracket 10 of the cross-tie has its upper portion perforated for the reception of bolts which secure a waist-sheet to the surface 16 of the cross-tie. The lower edge of the waist-sheet rests upon a ledge 17.

Projecting from each foot portion on one side of the cross-tie are bearings 14 for a driving spring-link (l.

The entire structure is made in a single casting, preferably of steel, is substantial, and can be readily located in position on the main frame of the locomotive, and the several parts can be accurately placed, as the cross-tie is finished prior to being located in position in the main frame.

I claim A cross-tie for the guide bearer of a locomotive, having feet which rest on the longitudinal side frames of the locomotive; an arched central body portion extending considerably above the feet; integral curved brackets at each end of the body portion and projecting beyond the side frames of the 10- 'comotive, said brackets having plates at their ends to which the side cross-head guides may be secured, the arched central body portion having a flat surface to which the central cross-head guide may be secured, one of said brackets extending above the other and having flat surfaces to receive the bracket bearings for a rock-shaft of the valve mechanism, each bracket being perforated for the reception of bolts which secure a waist-sheet to 85 the cross-tie; and a ledge on the side of each bracket upon which the waist-sheet rests.

LAWRENCE L. NEEBE.
