HEADLIGHT'.

SPECIFICATION forming part of Letters Patent No. 664,418, dated December 25, 1900. Application iiled October 1'7, 1899. Renewed October 18, 1900;' Serial No. 33,450. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, FRED B. LASH, a citizen of the United States, residing at Farmersburg, in the county of Sullivan and State of Indiana, have invented certain new and useful Improvements in Headlights; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in the construction and combination of parts necessary to provide a light designed, primarily, for use as a headlight upon a locomotive, though it will be found desirable and useful for all of the various purposes for which a concentrated light of great brilliancy may be used.

The prime object of my invention is to provide a reiiector for my headlight which will have great capacity to concentrate or reflect a light and direct it to a given point.

A further object is to provide reliably-eilicient means by which the reflector may be reliably adjusted and securely held in its operative position without liability of its exterior coating of Quicksilver or the like being injured or without fear that the reflector will become broken.

A further object of my invention is to provide means for quickly generating a gas from gasolene or similar oil, as will be hereinafter fully set forth, the details of my inventionbeing illustrated in the accompanying drawings, in which- Figure 1 isa central vertical section of a headlight provided with a portion of the tubl ing comprised in my invention and showing the relative location of the burner, chimney, and contiguous parts. Fig. 2 shows a central vertical section of a portion of the oilconveying pipe shown in Fig. 1 supplied with means to quickly generate gas "from the oil. Fig. 3 illustratesa transverse section of the reflector and its cushion of rubber and exterior casing, and illustrating another disposition of the gas-conveying pipe from the position thereby occupied in Fig. 1. Fig. 4 is a central longitudinal section of another form of r reflector from that presented in Fig. 1.

Fig. 5 illustrates a varied construction for the conveyerpipe.

For convenience of designation the several parts of my invention and their coperating features Will be referred to by numbers, of-

Which 1 illustrates the exterior casing of the headlight, which may be formed in any preferred Way and provided with the usual vent 2, designed to permit the escape of the products of combustion, as is usual, it being understood that the body of the headlight thus provided may be att-ached at any desired point, as upon the bracket 3 of a locomotive, by means of bolts passing through the base, section 4 or otherwise. Within the housing thus or otherwise provided I dispose my improved reflector, Which consists of the reflector proper, 5, formed preferably of glass and molded and shaped as illustrated in Figs. l or 4, or otherwise, as may be deemed productive of the best results, and the outside thereof is coated in the usual Way with a quicksilver compound designed to make this portion of the reflector entirely impervious to light, and thereby enable the reflector to concentrate the rays of the light and direct the same to any desired point.

An integral radial fiange 6 is formed upon the rim of the reflector proper, designed for the purpose of holding the reflector in an adj usted position, as by means of bolts 7, passing through the contiguous wall S of the housing, as clearly shown in Fig. 1.

After the reflector proper has been provided with a coating of quicksilver or its equivalent itis fitted with the jacket 9, which is designed to cover all exterior parts of the reflector from the flange 6 inward, said jacket being preferably formed of rubber, though other yielding material may be found desirable, the object in thus providing this covering or jacket being to cushion the reflector proper and hold the same securely in position without liability of injuring the surface formed by the quicksilver dressing, inasmuch as the rubber jacket will cling tightly around its exterior coating from .becoming injured,

' tween the outer casing and the reiiector.

In order to securely inclose the reflector proper and its cushion of rubber, I provide the exterior casing 10, formed of some suiti able sheet metal shaped so as to snugly it said parts, and in order that the casing may be held into cooperative relationship with said interior parts I form thereon a radial flange 11, designed to cooperate with the flange 6 upon the reector proper, and it is clear that by reference to Fig. 1 the bolt 7, after passing through the wall 8, is extended through suitable aperturesin the anges 6 and 11 and secured by a suitable nut, and thereby locking all of said parts closely together andinsuring that the reflector, with its outer casing, will be disposed within the housing l in a proper Way to coperate with the lamp 12, which may be of any preferred construction and is preferably provided' with the usual mantle 13, designed to render the light incaudescent.

It will be understood that a suitable lens 14 is secured to the outside of the wall 8 in such position that it will coperate with the reflector, the said lens being held in position in any preferred Way, as by the extension or casing 15, secured to the wall 8 in any preferred way, preferably by hinges, so that said lensmay be moved out of the way to render the lamp or the interior of the refiector readily accessible, as for purposes of repair or for cleansing said parts.

Suitable apertures 16 are provided in the reiector and its outer casings designed to permit proper draft to the lamp and to allow the chimney thereof to extend upward into the housing, as shown in Fig. 1, and in order to support the lamp in its adjusted operative position I provide at a suitable point beneath the lower aperture 16 the bracket 17, to which I secure the exit or vent portion 18 of the conveyer-pipe 19. The working parts of the lamp are secured to the end of the vent-pipe 18 in any preferred way, as is usual.

The conveyor-pipe 19, as will be seen by reference to Fig. 1, extends upward to a point above the re Hector, where it terminates in the inwardly-directed right-angled extension 20,

having the flared end 21 designed to receive the free end of the supply-pipe 22, which extends upward to the oil-tank 23 located at any Vpreferred point upon the exterior of the housing 1, the supply of oil from said tank being regulated or controlled by the valve 24.

end 21 of the conveyer-pipe 19, and by such pipe delivered to the lamp through the Vent 18.

In order to insure that the oiljemployed as fuel shall be readily converted into a gaseous state, I dispose with-in the supply-pipe an auxiliary flue, consisting of the U-shaped pipe 26, having the flared receiving end 27 and the flared terminal 28, it being understood that in order that the auxiliary tube or flue 26 may be readily introduced. within the supply-pipe the latter is made in sections, as

'indicated by the

joints

29 and 30, thus enabling said parts to be very cheaply man ufactured and quickly assembled in their respective operative positions. The construction illustrated in Fig. 2 is upon a slightly-enlarged scale, it being understood that all of the parts shown in said View are wholl y inclosed in the housing 1. By this arrangement it is therefore obvious that the vent or terminal 28 will discharge any heat productsinto the housing,

p from whence they will escape through the vent 2. The heat products from the chimney will enter the flared end 27 and pass through the U- shaped pipe 26, and from thence into theupper'portion of the housing 1, from whence they will escape through the vent 28, thus practically increasing the heating-surface applied to the oil, inasmuch as the heat from the `lamp will not only pass through the auxiliary flue thus provided but will also act upon the .exterior of the supply-pipe within which said line is disposed.

In Fig. 3 I have shown that the conveyerpipe 19 may be disposed laterally `or to .one side of the position occupied by the lamp instead of to the rear thereof, as'shown inFig. l, it being understood that the position of said pipe may be determined by expediency.

In Fig. 5 I have illustrated still another construction which may be adopted in forming the supply-pipe, wherein it will be observed that a coil-pipe formed out of said supplypipe is disposed immediately over the flue and consists in so shaping said pipe that a series of outer coils 3l is formed, and after a sufficient number of said coils have been provided the'end of the pipe is turned down lthrough the center of said coils, as indicated Vrable permanent character and that the several parts thereof may be very cheaply man- It will be understood that the dispositionE of the supply-pipe 22 shall be so made that it will be placed immediately over the end of.. the chimney 25 in order that the heat from; `the lamp Will result in the generation of gas` from the oil, which gas as it leaves the sup- Vply-pipe 22 will 'be' conducted into the flared:`

substantial equivalent thereof, and I do not therefore wish to be conned strictly to the exact showing herein made.

IOO

IIO

The cushion 9, it is obvious, will absorb the blows' and jars incident to the usage of 1my improved reector upon a locomotive or other moving mechanism, thereby -insuring that the reflector proper, formed of glass, will be fully protected.

Having thus fully described the construction of my invention, what I claim as new, and desire to secure by Letters Patent, is

l. As an improvementv in headlights, the combination with a suitable housing, of a reflector disposed within said housing, and having a radial flange; a metallic casing fitting said reiector; a cushion of rubber or the like interposed between said casing and reflector; a suitable lamp mounted within the same and having its chimney extending through said reflector and casing; a conveyer-pipe coperating with said lamp, in combination with a supply-tube coperating with said conveyertube and having an auxiliary Hue extending through a portion of its length whereby the heat of the chimney will be directed through said fiue and thereby more quickly transform the oil into gas in the manner 'specified and for the purpose set forth.

2. The herein-described headlightcompris ing an exterior housing 1; a reiiector proper having a jacket of rubber and an exterior casing of metal disposed within said housing and means to hold said parts in an adjusted position, in combination with a lamp mounted within said reiector and an oil-supply pipe having an auxiliary iiue disposed iu the interior thereof whereby the oil will be more quickly vaporized by the heat of the lamp passing through it in the manner specified and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
