HEADLIGHT.

Application filed January 6, 1922. Serial No. 527,415.

T 0 all whom it may concern:

Be it known that I, Mosns J. DAVIS, a citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented a new and useful Headlight, of which the following is specification. i

This invention relates to headlights primarily designed for use on loconiotiVes'although the improvement constituting this invention can also be embodied in connection with automobile headlights, etc.

It is an object of the invention to provide a headlight which can be quickly changed so as to throw either a white or a colored light (preferably red).

A further object is to provide a structure in the form of an attachment which can be applied readily to headlights already in use and by means of which the light can be changed from white to a color such as red.

An object of the present invention is to provide a means whereby in an emergency the light projected from the headlight can be changed to red so as to serve as a danger signal.

.Another object is to provide a structure of this character which is simple, durable and compact and can be easily operated.

VVith' the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a front elevation of a headlight having the present improvements combined therewith, parts being broken away.

Figure 2 is a side elevation thereof, parts being shown in section.

Figure 3 is a section through a portion of the device.

Figure 4 is a rear elevation of the attachment, a portion being broken away.

Referring to the figures by characters of reference 1 designates a cylindrical headlight housing of the usual or any preferred construction, the same being provided with a transparent lens 2 for throwing a white light;

The attachment constituting the present invention includes a rear cross bar 3 and a front cross bar 4-,these bars being attached to the front and back of the headlight housing and being secured at their ends to side rails 5 the forward ends of which are downturned as indicated at 6 so as to extend to opposite sides of the lens 2. Formed Wltlll-fl the inn-er sides of the rails 5 are longitudinal channels 7, these channels extending down wardly within the downturned portion 6 as shown in Figure 3. A cover plate 8 is secured on the rails and covers the space therebetween, this plate being provided with a central raised portion 9 extending longitudinally thereof.

Mounted to travel within the channels 7 are the ends of parallel cross rods 10 and 11, these rods being secured to the rim or frame 12 of a colored lens 13. An arm 14: is extended from the rod 10 and is pivotally connected to an actuating rod 15 which extends rearwardly under the raisedportion 9 of the cover plate 8 and to any convenient point where it can be reached readily for the purpose of actuating the movable lens.

Under normal conditions the rods 10 and i 11 are seated between the upper or horizontal portions of the rails 5 so that the lens 13 and its frame 12 are thus housedbetween rods 10 and 11 to slide forwardly within the channels 7 and thence downwardly w'thin those portions of the channels in the depending portions 6 of the rails. Thus the lens 13 and its frame 12 will be projected forwardly and swung downwardly so as to cover the white lens 2 and cause a colored light to be projected. By pulling backwardly on the rod 15 the lens 13 will be brought back to position between the hous ing 1 and the plate 8 Obviously, therefore, the color of the light projected from the headlight can be quickly changed in an emergency.

The device described can be applied readily to headlights already in use and is not only efficient for use in connection with locomotives but can also be used, to advantage on automobileheadlights,etc. Yhile ill) a red lens is preferably used it is to be understod that lenses of other colors can be employed when desired.

It is to be understood that the rod 15 can be mounted within a suitable guide such as shown at 16 in Figure 4, thereby to hold the rod in proper relation at all times to the arm 14.

What is claimed is 1. The combination with the cylindrical headlight housing of a locomotive or the like, of a one-piece supplemental lens normally housed above and outside the housing, means for sliding the lens, and means for guiding said lens during its sliding movement, from the top of the housing down wardly into position across the lens of the housing, and a cover plate extending over the housing for protecting the lens while in position above the housing.

2. The combination with a cylindrical headlight housing, of parallel guide rails supported above and upon the top of the housing and having downwardly extending front end port-ions, cross members slidably engaging the rails, a one-piece lens fixedly connected to the cross members and normally supported thereby above the housing and between the rails, and means for sliding the cross members, said rails constituting means for guiding the sliding cross members to position across the upper and lower portions of the housing lens thereby to support the one-piece lens in position across the front of the housing.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
