, LAMP FOR AUTOS AND OTHER VEHICLES AND PURPOSES- To all whom, it may concern:

Be it known that I, NICOLAS LOEWENSTEIN, a subject of the Czar of Russia, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Lamp for Autos and other Vehicles and Purposes, of which the following is a specification.

My invention consists of a lamp embodying a reflector of novel construction, whereby great brilliancy of light is attained, a plurality of lenses, whereby the volume of reflected light is vastly increased in field and brilliancy, and other details of construction are presented, as-will be hereinafter described, the novel features being pointed out in the claims.

Figure 1 represents a front elevation of a lamp embodying my invention. Fig. 2 represents a longitudinal vertical section thereof. Fig. 3 represents a side elevation of another embodiment of the invention.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates the casing of the lamp, and B designates the burner thereof, the latter being of the order of acetylene, the carbid for which is carried in the chamber (1,.which is attached to the casing A, as in Fig. l, or supplied by the attachment D, which extends to a place of storage of said material in the auto or vehicle on which the lamp is used.

E designates the reflector of the lamp, the same being constructed of suitable metal or other material with reflecting-surfaces and composed of the rear portion F, which is of the form of a prolate spheroid, and the front portion Gr, which is of the form of the frustum of a cone, the narrow end of which joins the wide end of the portion F, it being noticed that the narrow end of the latter is closed and that the burner B is within said portion F, backed by the closed end thereof, whereby the rays of light from said burner are gathered by the reflecting-surface of the portion F and concentrated within said portion, in which condition the light in a highly-brilliant condition is transmitted against the reflectingsurface thereof and again subjected to the action thereof, whereby there is further increase in the brilliancy of the light, the effect of which is evident, it being also noticed that the portions F Gr of the reflector are practically continuities, being broken only by the openings hereinafter described, thus provid- Specification of Letters Patent.

ing practically unbroken reflecting-surfaces on said portions, which cause a unlformlty.

In the casing in front of the reflector is the lens H, and in front of the latter is the lens J, both properly supported, it being noticed that the lens H is of less diameter than the lens J, but is of more powerful nature, it occupying, as is evident, a portion rearward of the center of said lens J and foward of the center of the closed rear end of the portion F of the reflector, by which provision the volume of reflected light is condensed into a beam, producing a large field of the same, possessing great brilliancy, especially as the support of the inner lens is of skeleton form, it being composed of arms which are secured to the casing, so that there is a space in the casing around the periphery of said inner lens, the same being comparatively unobstructed, and thus the light of the burner is reflected not only to and through the inner lens, but also around the same, and so reaches the outer lensin comparatively two different streams, one of which is directed to the peripheral portion of the outer lens, which is not fully reached by the light from the inner lens.

In the lower part of the casing A are openings K and in the portion F of the reflector are openings L for the admission of air to the burner B. Above the burner there is an opening M, which is in communication with an opening N in the top of the casing, whereby there is an outlet for the products of combustion from the burner.

Secured to the casing above the opening N is the hood P, which is closed in front and open in the rear, whereby while the products of combustion, as aforesaid, may escape from the casing said hood acts as a guard for preventing downward drafts of air from reaching the burner, so that puffing and irregularity of the light of the burner is obviated; but the rear wall Q of the opening N acts as a deflector for some of the products of combustion, whereby they return into the space R between the back of the chamber 0, and so enter the openings L, thus supplying the burner with warm air, the effect of which is evident.

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

1. In a lamp, a reflector composed of members, the rear one of which is in the form of a prolate spheroid, and the front one of which is that of a cone, the reflecting-surfaces of said members being practically continuities and in unbroken planes, the burner of the lamp occupying the rear member of said reflector and located entirely within the same, a casing and a plurality of differential lenses on said casing, one behind the other and both in front of said reflector, the inner lens being supported by arms, so that a comparatively unobstructed space exists in the casing around the periphery of said lens.

2. In a lamp, a reflector having openings in its lower portion and an opening in its upper portion, an interior casing in which the same is contained, annular exterior means for directing the products of combustion from said lamp, and a guard on the casing over said means.

3. In a lamp, a reflector having openings in its lower side, an interior casing in which in its lower portion, a casing therefor having an opening with one Wall extended over the outlet forming a deflector for the products of combustion from the burner, and a hood over said opening, whereby a portion of the products of combustion are returned through said openings in the reflector to supply the burner with warm air.
