Specification of Letters l n Patented Dec. 8, 1914.

Application filed February 4, 1814. Serial No. 816,440.

To all whom it may concern Be it known that I, JULIUS Rounn, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented new and useful Improvements in Locomotive-Headlight Covers, of which the following is a specification.

In the operation of locomotive engines after dark it is customary when entering cities or other places thickly populated to dim the headlight so as to prevent blinding persons and animals by the intense glare.

The present invention provides novel means whereby the headlight cover may be operated from the cab of the engine without subjecting the fireman or other attendant to any risk or unnecessary exposure.

The invention further consists of peculiar supporting means and actuating devices for the cover, the actuating means embodying members which have a relative play to adits own weight after passing the dead center in either direction, such arrangement of parts ,preventing the actuating means from stopping upon a dead point with the result that the cover may be positively moved from either position when required. The invention also further consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated and claimed.

In the drawing hereto attached-Figure 1 is a side view of a locomotive headlight showing the same in position and embodying the invention, the full lines showing the cover thrown back and the dotted lines illustrating the position of the cover and actuating means when said cover is moved to a position in front of the headlight. Fig. 3 is a front view. Fig. 3 is a horizontal section on the line y-y of Fig. 1. Fig. 4 is a vertical section 0 the cover and front portion of the headlight on the line awe of Fig. 2. Fig. 5 is a detail'view.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawing, by the same reference characters.

The numeral 1 designates a headlight such as commonly provided for locomotive engines. A bracket 2 is secured to a side of the headlight and forms a support for the operating parts. An arm 3 is mounted in the bracket 2 and is provided with a lateral extension l at its swinging end to which the cover 5 is attached. T he 5 fastening 6 by means of which the cover5 is attachedto the lateral extension brace such part 4: and admit of the cover 5 having a limited play, such movement being determined by means of opposed lugs 7 at the end of the part 4, such lugs constituting stops. Two of the fastenings 6 are arrange upon opposite sides of the lugs 7 and close thereto so as to prevent longitudinal movement of the cover 5 upon the part l. he pivotal movement of the cover 5 upon the art 4 enables such cover to fit close against either the front or the back light as indicated by lines in Fig. 1. A keeper 8 is arranged upon the back of the headlight to receive the lower portion of the cover when the same is swinging to a position in the rear of the headlight so as to be out of the way. plurality of clips 9 are located at the front of the headlight to receive the cover an hold the same in horizontal position when swinging to a point to cover the headlight. The clips 9 are located one at the bottom and two at the sides of the front so as to receive the lower portion of the cover an cause the same to fit close against the front of the headlight. An opening 10 is formed in the upper portion of the cover 5 in position to register with the part of the lens of the headlight provided with the number to admit .of such number being read. be opening 10 is covered by mica or other material to dim the rays of light shed therethrough. A crank 11 is mounted loosely upon an extension of the bent end 12 of the arm 3 which is journaled in the bearing portion of the bracket 2. The crank 11 is formed at its upper end with bifurcations 13 which have lateral extensions 14 at their extremities arranged in the path of the arm 3 to engage the same. The crank 11 has a limited movement which is determined by means of stops 15, the latter consisting of lateral extensions at the ends of a cross bar 16 forming a part of the bracket 2. The stops 15 prevent the crank 11 from reaching a dead point and enable the cover 5 to be readily operated in either position. A rod 17 is connected at one end with the crank 11 by means of a crank 18 and its opposite end 4 are of a nature to emterminates Within the cab of the locomotive engine in position to be conveniently grasped and operated when it is required to move the cover 5 to extend in front of the headlight or to expose such headlight. A guide tube 19 at the side of the engine receives the operating rod 17 and directs the same in its movements and enables a comparatively light rod being employed.

When the locomotive engine is upon the road the headlight is uncovered by having the cover 5 occupying a position in the rear thereof as indicated by the full lines in Fig. 1. Upon approaching a city or other populated district requiringthe headlight to be dimmed the operating rod 17 is manipulated to throw the cover 5 from the point in the rear of the headlight to a point in front thereof as indicated by the dotted lines in Fig. 1. This operation is adapted to be performed with ease andconvenience without subjecting the attendant to any risk or exposure as will be readily understood.

From the foregoing description, taken in connection with the acompanying drawing,

the advantages of the construction and of the method of operation will be readily apparent to those skilled in 'the'art to which he invention appertains, and While I have described the principle of operation of the invention, together with the device which I nowconsider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the invention asclaimed.

carried by such .pivoted arm to move Having thus described the invention what is claimed as new, is

1. In a locomotive headlight, the combination of .a cover therefor, a pivotally mounted arm having a lateral extension formed with opposed lugs constituting stops and fastening means securing the cover to the lateral extension of the arm and admitting of such cover having a limited pivotal movement upon the arm.

2. In a locomotive headlight, the combination of a pivotally mounted arm, a cover thrown to a position in front of the headarm and adapted to be.

light, a crank, operating means connected with the crank and adapted to be actuated from the cab of the locomotive engine, and connecting means between such crank and the latter past a dead center in either direction, such arm and the cover carried thereby continuing its movement by gravitative action to the predetermined point.

3. In a locomotive headlight, the combination of a pivoted arm, a cover carried by the pivoted arm and an operating crank having bifurcations formed with stops which extend upon opposite sides of the pivoted arm to move the latter past a dead center in each direction upon operating the crank to throw the cover into or out of operative position.

In testimony whereof I aflix my signature in presence of two Witnesses.
