CLYDE C. FARMER, 0E PITTSBURGH, PENNSYLVANIA, ASEwIGNOB TO THE TESTING- HOUSE AIR BRAKE COMPANY, 015 VJILMERDING, FPENNSYLVANIA, A GORIPORATION OF PENNSYLVANIA.
SAFETY CONTROLLER, HANDLE.
Application filed December 1, 1921.
To all whom it may concern.
Be it known that I, Cums C. FARMER, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Safety Controller Handles, of which the following is a specification.
This invention relates to electric car mo tor controllers in which a safety controller handle is provided such that the release of the controller handle operates to automatically cause an application of the brakes and the opening of the power circuit.
The principal object of my invention is to provide an adapter unit by which a standard safety controller handle unit may be applied to motor controllers of different types without altering the motor controller construction or the safety controller handle unit.
In the accompanying drawing, the single figure is a vertical section of the upper portion of a motor controller with a safety controller handle applied thereto in accordance with my invention.
In the drawing, the reference numeral 1 indicates the top plate of an electric motor controller and in the particular type of controller shown, the plate 1 is provided with a central sleeve portion 2 through which the controller shaft 3 extends. The upper end of the shaft 3 is provided with pins 4: which, in the ordinary controller. are adapted to engage in corresponding holes in the controller handle when the same is applied to the controller. The sleeve portion 2 is provided with an annular groove 5 for receiving the end of a set screw by which the handle is held in position on the controller shaft. A yielding stop device 6 is also provided, which yieldingly engages notches in the controller handle for defining the different operating positions thereof.
Accordingto my invention, in order to apply a safety controller handle unit to the controller without requiring alteration of the handle unit or the controller, an adapter is provided, which may comprise an extension shaft member 7. An adapter is designed for each differing type of motor controller, so that the adapter may be applied to the controller in place of the usual controller handle.
Serial No. 519,170.
In the particular type of controller shown in the drawing, as an example, the adapter is provided with a socket adapted to fit over the sleeve portion 2 and bores adapted to register with the pins l, and corresponding with the construction of the ordinary con troller handle. A set screw 8, having screwthrea'ded engagementin the member 7, is screwed down, after the extension shaft is applied, so that the end of the screw engages in the groove 5, to hold the shaft in posi tion and the extension shaft is also provided with notches, corresponding with the notches on the usual controller handle, for cooperation with the yielding stop device 6.
The standard controller handle unit may comprise main casting 9, to which is ap plied a housing base and in which is mounted a controller handle 11, the release of which is adapted to effect an application of the brakes and the opening of the power circuit in the well known manner. The extension shaft 7 is provided with a key section 12, and the main casting of the safety controller handle unit with a key aperture for receiving the key section 12. The housing base 10 may be secured to the yielding stop housing 13 of the controller by means of one or more screws 14E and then the controller handle unit may be applied to the key section 12. i
It will be evident that different adapters may be provided for application to various types of motor controllers in place of the usual controller handle, each adapter, however, having the same key section by which a standard safety controller handle may be applied to the controller without alteration.
Having now described my invention, what I claim as new and desire to secure by Letters Patent, is v The combination with an electric motor controller having means for receiving the usual controller handle, of an extension shaft constructed for application in place of the usual controller handle and provided with a key section, and a safety controller handle unit having a key aperture for receiving the key section of the extension shaft.
In testimony whereof I have hereunto set my hand.
CLYDE C. FARMER.
