CROSSTIE FOR ELECTRIC LOCOMOTIVES.
Application filed October 3, 1927. Serial No. 223,656.
The object of my invention is to make an integral cast metal cross-tie, in which the brake-cylinders form an integral portion of the cross-tie. p.
Y In the accompanying drawings:
Fig. 1 is a sectional planview on the line- 1-1, Fig. 2;
Fig. 2 is a sectional view on the line 2-2, Fig. l;
Fig. 3 is an end View; and
Fig. 4 is a sectional view on the line 1-4, Fig. 2.
This present application is a companion to one filed by me on the 1st day of October, 1927, under VSerial No. 223,343, in which space has been provided for the reception of separate brake-cylinders.
In the present instance, the brake-cylinders are an integral part of the structure.
lThe cross-tie 10, in the present instance, is in the form of an integral casting and is of sucient depth to form a rigid connection between the two side members of the locomotive frame, the side members bei ng shown by dotted lines 11, Fig. 2.
The centre bearing 12 is at the upper portion of the cross-tie and projects slightly above the body of the cross-tie as clearly shown in Fig. 2. 13 are the side bearings, which are integral with the structure. 111 are the brake-fulcrum which are also made integral with the structure, and 15 vare integral motor-suspension lugs.
The frame of the cross-tie in the rpresent instance consists oit' a longitudinal central plate 16, side plates 17, and end plat-es V18. There are openings in these several plates so as to lighten the structure and so that access may be had to the interior of thecross-tie.
The cross-tie is closed at the top by a plate 19 and at the bottom by a plate 20, and connecting the top and bottom plates are trans verse plates 21.
At each end of the structure within the end plates 18 are integral brake-cylinders 22,
which extend partly below and partly above the top plate 19, as shown in F ig. 2. Within shown in Fig. 4. Bolts secure these heads to the body of the cylindersin the presentin stance. f
The cross-tie may be made without the in# tegral motcisuspension lugs, and the crosstie canvbe applied to any rail conveyance, either motive power, passenger, or freight equipment.
By this invention am enabled to make the lnake-cylinders as integral parts of the cross-tie.
I claim 1. A cross-tie made as an integral casting, having a box-like body portion; integral side bearings extending above lthe body portion; and horizontally arranged integral brakecylinders located partly above and partly below the top plate of the structure.
2. A cross-tie made as a unitary cast structure, having a box-like body portion, with a longitudinal internal plate and two transverse reinforcing plates at the centre; a centre bearing; side bearings; two integral brake cylinders, one at each end of the structure; and projecting brake-hangers, said brakecylinders also being made integral withvtlie structure. i
3. A Y cross-tie for a locomotive frame,
' made as an integral casting` and arranged to lit between the side frames ot the locomotive and to form a rigid connection between the two frames, and having a brake cylinder cast integral therewith. i i
L1. A cross-tie for a locomotive traine, made as an integral casting andrarrang'ed to be located between the side frames of the locomotive and to be rigidly secured thereto, and having' a brak-e cylinder at each end thereof cast integral therewith.
