ELECTRIC LOCOMOTIVE.

Specification of Letters Patent.

Application filed August 26, 1909. Serial No. 514,707.

To all whom it may concern:

Be it known that 1, WILLIAM E. Wool)- ARI), of Schenectady, in the county of Schenectady and State of New York, have invented a certain new and useful Improvement in Electric Locomotives, of which improvement the following is a specification.

The object of my invention is to provide an electric locomotive of such construction as will facilitate and economize time in the installation of the electrical apparatus, enable the amount of cable requlred to be reduced, and render the apparatus more readily accessible than heretofore for inspection and repairs.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure 1 is a side view, in elevation, of an electric locomotive illustrating an application of my invention; Fig. 2, a similar view, on an enlarged scale, of the independent bed and electrical apparatus detached; Fig. 3, a vertical transverse section, on the line a a of Fig. 2; and, Fig. 4:, an end view, in elevation.

In electric locomotives of the construction known prior to my invention, the auxiliary electric apparatus is mounted directly on the frame and cab, and the ordinary method of construction is to first build the locomotive frame and cab (with auxiliary cabs if required) after which the control and auxiliary electric apparatus is attached, the connecting cables being run as the apparatus is mounted. It results from this method, that the otherwise completed locomotive often remains several weeks in the erecting shop while the electrical apparatus is being installed.

The leading and characteristic feature of my invention consists in a frame or bed which is adapted to support and carry the auxiliary electric apparatus of an electric locomotive, and which is wholly independent of the locomotive structure proper, z'. a, the frame and. cab thereof. The construction of the frame or bed is such that the auxiliary electric apparatus can be assembled thereon, and all the necessary interconnections made, at any convenient point in the works of the manufacturers of electric apparatus, before the frame or bed is secured in place upon the locomotive frame. This work can be carried on simultaneously with the construction of the locomotive frame and cab in another shop or department, and when the locomotive proper is ready for erection, the frame, and the electrical apparatus mounted thereon, can be brought to the locomotive and put in place when the frame and cab are being erected. By reason of the control and auxiliary apparatus being mounted on an independent frame or bed, the wiring can be done more readily and quickly than under the present practice, as .the frame can be placed, for the purpose, in a shop where all the facilities for wiring are at hand. The assemblage of the auxiliary apparatus upon the independent frame or bed, admits of grouping the apparatus, so as to reduce the amount of cable required in ordinary constructions, and also renders the apparatus more readily accessible for inspection and repairs. After the independent bed or frame and the apparatus thereon are secured in position on the locomotive, connection is made to the trolley pole or third rail shoes, as the case may be, and to the lighting, heating, and air compressor circuits.

' Referring to the drawings, my invention is exemplified as applied in an electric locomotive having a main supporting frame, 1, of any suitable known construction, upon which is secured a cab, 8, and which is carried on driving wheels, 4-, to which power is imparted from electric motors, through connections of any suitable and preferred design, which do not constitute part of my present invention and are not therefore herein shown. In the practice of my invention, I provide an independent frame or bed, which is ordinarily of substantially rectangular form, and is preferably of metal, being, in this instance, shown as composed of lower lateral and central channel bars 9, 9, connected by transverse members, 9", and upper central channel bars, 9, which are connected to the lower channel bars by vertical end members, 9. A flooring of wood or other insulating material, 10, is secured upon the top of the lower channel bars, and a beam, 11, of wood, extends centrally from one end plate to the other, about midway between the upper and lower channel bars. A vertical switch board, 12, is connected to one of the end plates, by bolts, 12 passing through interposed distance pieces, 12, of insulating material. The frame or bed, which is secured detachably to the main frame of the locomotive by bolts passing through the lower flanges of the lower lateral channels, serves as the support of the control and electrical apparatus, which in and of itself, does not form part of my present invention. Eyes or sockets, 9 are secured to the upper channel bars, for the purpose of raising and lowering the frame as required,

In the instance shown, the resistance boxes, 13, and the reversing switch, 14, are mounted on the flooring, 10, the contactors, 15, are supported above them, and the main switch, 16, and lighting, heating, and air control switches, 17, 18, and 19, are mounted on the switch board, 12. Cables, 20 and 21, extend from the resistance boxes, 13, and contactors, 15, to a junction box located on the switch board. If desired, the independ ent bed or frame may be extended sufficiently to serve as a support for the controllers.

The construction shown is one which is more particularly adapted for application in a comparatively light locomotive, and in the case of heavy locomotives, it may be found advisable to use two independent frames or beds, and divide the auxiliary apparatus between them, connections being made by cables and junction boxes, in the ordinary manner.

I claim as my invention and desire to secure by Letters Patent:

1. The combination, in an electric locomotive, of a main supporting frame, a separate and independent frame or bed adapted for the reception and support of assembled members of auxiliary electrical apparatus, and connected detachably to said main frame, and auxiliary electrical apparatus mounted on said frame or bed.

2. The combination, in an electric locomotive, of a main supporting frame, a separate and independent frame 01' bed adapted for the reception and support of ZlSStlllblGtl members of auxiliary electrical apparatus, and connected detachably to said main frame, auxiliary electrical apparatus mounted on said frame or bed, and a cab inclosing said frame or bed and the apparatus thereon. 3. An independent frame or bed for sup porting auxiliary electrical apparatus of electric locomotives, comprising a metal base and top, vertical end members connecting said base and top, and a flooring of insulating material supported on the base.

4. An independent frame or bed for supporting auxiliary electrical apparatus of electric locomotives, comprising lateral and central base channel bars connected by transverse members, central top channel bars, and vertical end members connecting the base and top channel bars.
