Application filedApril 19,1901. SerialNo. 56,529. (Nomodel-l To all whom it may concern:
Be it known that I, GUY L. FAIRBROTHER, a citizen of the United States, residing at Thompsonville, in the county ofHartford and State of Connecticut, have invented certain new and useful Improvements in Electrical- Controller Attachments, of which the following is a specification.
This invention relates to a device designed to be attached to an electric controller for the purpose of requiring the handle to stop at each notch when the motorman is turning on the power.
The object of the invention is to provide a simple, inexpensive, and easily-operated device of this nature which may be quickly attached to and removed from the electric carcontrollers in common use. p
The embodiment of the invention that is illustrated by the accompanying drawings has an annular plate with radial mortises containing outwardly-spring-pressed bolts that when the plate is set upon the top of the controller about the end of the spindle project into the path of 'a part of the handle a little in advance of the several notches and obstruct the movements of the handle until they are forced into the plate by a finger-lever carried by the handle.
Figure 1 of the views shows a plan ofone of the attachments placed upon the end of a common controller. Fig. 2 shows a plan of the attachment with a part of the cover broken away and one of the bolts forced in. Fig. 3
shows a vertical section of the attachment on the plane indicated bythe broken line 00 a: on
Fig. 1, the handle being shown in the position indicated by the 'dotted outline on Fig. 1, where it is obstructed by one of the bolts. Fig. 4 shows a transversesection of the controller-handle on the plane y yon Fig. 3; and Fig. 5 shows a vertical section similar to that shown in Fig. 3, with one of the bolts pushed in by the finger-lever, so that the handle may be advanced another step. The controller 1, that is shown in the views, is one of the so-called Westinghouse type,
' having the ordinary spindle 2, with operating-handle 3 and reversing-handle 4. The operating-handle has the usual downwardlyprojecting lug 5, and adjacent to that lug it carries a finger-lever 6.
The plate 7 has a central perforation 8, so that it may be set upon the top of the controller about the end of the spindle, and has a foot 9 arranged to extend between the handle-stopping lugs 10 on the top of the controller and prevent the plate from moving when in position. The plate has radial inortises 11, in which are bolts 12, that have the front faces of their outer ends fiatand the back faces of their outer ends beveled. The
mortises are preferably smaller'at their outer ends, and the bolts taper so that they may freely move inwardly, but can only move outwardly a specified distance. In the face of the plate is an annular recess 13, in which a spring-ring let is arranged to press against the inner ends of the bolts and force them outwardly. A cover 15 is placed over the top of the plate to retain the bolts and spring in position. The mortises are so arranged that when the plate is in position upon the top of a controller a bolt projects outwardly a little in advance of each of the marks that are employed to indicate the notch-points, so that as the handle is advanced it willbe obstructed and stopped by a bolt over each mark. The handle is turned in the usual manner until it is stopped by a bolt. Then the finger-lever is oscillated and the obstructing-bolt forced into the plate out of the path of the handle. The handle is stopped at each notch and it is necessary to force in the obstructing-bolt before the handle can be advanced to'the next notch. With this construction it. is necessary on reaching each notch to stop the handle and depress the outer end of the finger-lever and force in a bolt. This can be very quickly accomplished; but it requires the motormau to make a complete stop at each notch, so that he cannot suddenly throw on all of the curboth ends of a car, the motorman transferring it with the operating-handle. I claim as my invention- ICO 1. A controller attachment consisting of a plate adapted to be placed upon a controller about the spindle, bolts loosely held by the plate, a spring for causing the bolts to project outwardly from the plate into the path of a part of the controller-handle, and a lever attached to the controller-handle adjacent to the ends of the bolts, substantially as specified.
2. A controller attachment consisting of a radially-mortised annular plate adapted to be placed upon a controller about the spindle, tapering bolts loosely held in the radial mortises and projecting beyond the periphery of the plate, a spring for thrusting the bolts outwardly, and a lever attached to the controllerhandle adjacent to the ends of the bolts, substantially as specified.
3. A controller attachment consisting of an annular plate having radially-arranged tapering mortises, an annular recess, a projecting foot, a removable cover, tapering bolts loosely held in the radial mortises with their ends projecting beyond the periphery of the plate, a spring for thrusting the bolts outwardl y, and a lever attached to the controllerhandle adjacent to the ends of the bolts, substantially as specified.
4. A controller attachment consisting of a plate adapted to be placed upon the top of a controller about. the spindle, bolts loosely held by the plate with their outer ends projecting beyond the periphery of the plate, means for thrusting the bolts outwardly, and means carried by the controller-handle for thrusting the bolts inwardly, substantially as specified.
