ELECTRIC HEADLIGHT.

Application filed October 14, 1921.

and exact description, such as will enable others skilled in the art to which it'appertains to make and. use the same. a

This invention relates to electric head-.

lights, and has for its main object to provide a serviceable and inexpensive headlight of such construction that the lens, reflector and lamp can be removed quickly and without the necessity of first removing a number of small screws orother retaining devices that are dificult to handle or manipulate.

Another object is to provide an'electric headlight which is equipped with a divided casing that is constructed in such a manner that when it is open or the sections of same separated, the lens, reflector and lam will be exposed to view and can be easi y removed. Other objects and desirable features of our invention-will be hereinafter pointed out. To this end we have devised headlight that is rovided with a casing composed of a plura lty of sections separated or divided by joints which extend longitudinally of the casing and provided on their inner sides with ribs, coves or the like that hold the lens and t e reflector in a position at right angles to the lon itudinal axis of'the casing.- Gne element 0 the easing is provided with a support for the socket that holds the incandescent'lamp oi the headlight, and a movable or adjustable element co-operates with said sup ort to re- .tainsaid socket in operative position.

Figure 1 of the drawings is a perspective view of an electric headlight constructed in,

accordance withour invention, showing the two sections of the casing se arated.

A and A designate two semi-cylindrical shaped members that cooperate with each other to form a cylindrical casing that houses anelectric incandenscent lamp B, a lens C and a reflector D; The joints between the members A- and A, are located preterably at the horizontal center of the casing haljf of the casing and the member A the top half. Said members can be connected together in any suitable way thatwillpermit them to be separated easily so as to expose the lens, lamp and'reflector, but we pjrsfer to connect said'members together by ges 1 so as to enable the top half .or section A of the casing to be swung into the pos1t1on shown 111 Figure 1 when it is desired to inspect or remove the elements of .the headlight that are arranged inside of the casing. Normally, is held clampedtifghtly member A by means of a fastening device whlch may consist of a screw: 2 pivotally connected by a pintle pin 3 to a pair of laterallyprojecting lugs 4 on the bottom member A and provided with a wing nut 5 that is adapted tb bear the topfmember A against the bottom lugs don the top section A of the casing, said screw being adapted to be swung on its pivot Into and out of engagement with the lugs i on the top section of the casing,

1e lens and the reflector are loosely mounted in transversely-disposed grooves 6 and 7, respectively, in the bottom section A of the casing, and the top section is pro vided with co-operating grooves 6 and 7 that receive said lens and reflector when the top section of the casing is moved into its closed position. The lamp B is mounted in a lamp socket 8 that is seated in a semi-circular-shaped supportt that extends transversel of the bottom member A oi the casing a j acent the rear end of same, said lamp socket being retained in position preferably by a'clam'ping member 10 pivotally connectedby a hin e l1 tothe transversel -disposed lamp soc et support and provi ed at lts free, end with an elongated slot 12 for an "upwardly-projecting, screwreceivin thread Stud 13 on-which a wing nut 14 is adapted to be mounted after the clamp 10 against a bifurcated I v aw or pair of laterallyprojecting an electric will form the lower has been swung downwardly into engagement with the socket,'as shown in full lines in Figure 3. When it is desired to adjust or i be formed from any suitable material, but

when the headlight is designed for use on an electric storage battery mine locomotive, we prefer to cast said members and provide the meeting. edges of same with laterally-projecting flanges 15, so that the top member of the casing will have a. firm bearing on the bottom member, the lugs and l and the ribs that form the grooves which receive the lens and the'reflector being integrally connected to the members of which they form a part;

In the form of our invention herein illustrated the bottom member A of the casing is provided with integral, laterally-projecting lugs 16 through which fastening-devices are passed to connect the headlight to the structure on which it is mounted. The lens C is preferably set inwardly some distance from the extreme front end of the casing, and the top member A of the casing is provided with a forwardly-projecting hood 17 that tends to protect the lens. Ventilating openings 18 are formed in -the top of the casing and the bottom part of the casing is pro vided with an air inlet opening '19 so as to cause air to circulate through the casing. If desired, the top member A may be provided on its outer side with integral hoods or shields 20 for preventing dirt from blowing into the casing through the ventilating openings 18 therein.

With a headli ht of the construction above described it is a very simple matter to inspect or remove the lens, reflector and lamp, owing to the fact that the casing is divided longitudinally into a number oi sections that can be easily separated, so as to expose the lens, reflector and lamp, the lens and reflector being loosely mounted in one section oi the casing and the lamp socket being retained in position by a hinged clamp secured by a wing nut. While our improved headlight is not limited to use with an electric storage battery mine locomotive, it is particularly adapted for such use, on account of its rugged construction and the ease with which the lens, lamp and reflector can be inspected or removed, it being unnecessary to remove 'or manipulate a number of.

small screws or other retaining devices to gain access to the interior of the casing or to remove the lens and reflector. In addition to the desirable features above pointed out, our improved headlight is inexpensive "to manufacture, as the casing is so designed that co-operating integral portions on the,

sections of same hold and clamp the lens and reflector in operative position.

Lesopoa Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. An electric headlight, comprising an electric lamp, a lens, a reflector, and a longitudinally-divided casing composed of a loosely mounted in one section of the ca ing and adapted to be engaged and clamped in position b the other section of the casing.

3. A hea ight provided with a casing composed of a plurality of sections that are separated from each other by joints that extend longitudinally of the casing, one of said sections being movable, a lens and a reflector loosely mounted in one section of the casing and adapted to be engaged and clamped in position by the movable section of the casing, a lamp socket inside of the casing, and a clamping device for retaining said lamp socket in position.

l. A. headlight provided with a longitudinally-divided casing composed of a stationary bottom part and a movable top part, means for securing said top part in its closed position, a lens and a reflector loosely arranged in transversely-disposed grooves in-said bottom and top parts, a lamp socket support in said bottom part, and a movable clamping device that co-operates with said support.

5. A headlight provided with a cylindrical-shaped casing com osed of two horizontally-divided sections inged together, a lens and a reflector positioned between said sections and held in position by integral devices on same, a lamp socket support on one of said sections, a hinged clamp co-operat- 'ing with said support, and a securing means for said clamp;

'6. A headlight provided with a cylin drical-shaped casing composed of two horizontally-divided sections, a lens and a reflector mounted loosely in the bottom section of'the casing, a lamp socket removably mounted. in the'bottom section of the casing, and a hinged securing device connected to one section of the casing and adapted to be swung into engagement with the other section when the casing is closed.
