LAMP AND ATTACHING MEANS THEREFOR.

Specification of Letters Patent.

Patented Jan. 27, 1914.

Application filed February 6, 1913. Serial No. 746,491.

To all whom it may concern Be it known that I, JOHANNES G. VON Jnmson, a citizen of the United States, residing at Linoleumville, 1n the county of Richmond and State of New York, have mvented certain new and useful Improvements in Lamps and Attaching Means Therefor, of which the following is a specification.

This invention comprehends improvements in lamps and relates more particularly'to those which are especially adapted for use on vehicles.

The primary object of the invention is the provision of a gas lamp of this type, which, because of its peculiar construction, Wlll never become overheated, which will be visible to a certain extent from the rear, and which will furnish a maximum amount of illumination.

Another object of the invention 1s to provide a novel spring support for the lamp and its generator.

With these and other ob ects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangementof parts, as will be hereinafter described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is a side elevation of my invention, Fig. 2 is a top plan view, Fig. 3 is a front elevation of the lamp proper, Fig. l is a fragmentary detail sectional view through the upper portion of the lamp body, and, Fig. 5 is a fragmentary detail sectional view taken on a horizontal plane, showing the construction of various parts to be hereinafter more particularly described.

In the following description and accompanying drawings, similar parts will be referred to and designated by like characters of reference.

Referring in detail to the drawings by numorals. Q designates, generally, my improved lamp, 6 an acetylene gas generator. and '7 a gas purifier. These last mentioned members form no part of the present invention, having been fully described and claimed in my pending application for improvements in acetylene gas generators, Serial No' 740,074, filed January 3, 1913.

The body portion of my improved lamp is double walled, having an external wall 8 and an internal wall 9. The intermediate portion 10 of the lamp body forms an essentially square chamber, the bottom 11 of which is aperturedto permit the passage of the burner 12 attached to the purifier 7. The side walls of the central portion 10 are apertured as at. 13, as clearly shown in Fig. 5. Supporting plates 14 project laterally from the exterior walls of the central portion 10 above and below the outermost apertures 13 and are for the purpose of retaining the colored lenses 15 and 16. It will be noted that the lenses of each pair converge toward their outer edges and are set at an angle to the sides of the lamp, whereby rays of light coming through the apertures 13, may be seen from the front and rear of the lamp.

The rear end of the lamp is closed by the walls 17 and 18, which are secured to the outer and inner walls respectively, of the body portion. Series of perforations 19 and 20 permit a circulation of air. The forward portion 21 of the lamp body is frusto-conical and is lined with a mirror having a wavy surface. The interior wall 9 is cxtended outwardly, as at 2, forwardly, as at 2i, and then again outwardly to provide a series of shoulders, the purpose of which will be hereinafter explaned. This wall is extended rearwardly, as at 25, and then inwardly, as at .26, and soldered or otherwise secured to the wall 8. A plurality of openings '27 permit air to flow freely around the outer end of the wall 8, as indicated by the arrows in Fig. If desiredfthc wall 9 and mirror :22 may be provided with coinciding openings 28 to permit an entrance of air into the interior of the lamp body.

A lens retaining ring 29 is hinged, as at 30, to the lamp body and is of such a shape as to conform with the angles formed by bending the wall 9, as indicated at 23 and 24. A plain concave-convex lens 31 and a similarly shaped lens 32 having a cut exterior surface 33 are secured in spaced relationship by the ring" 29. A spring catch 34 serves to lock the ring in its closed position. As clearly shown in Fig. 4, a perforated cylindrical housing 35 is secured to the top of the central portion 10 of the lamp body over the openings 36 formed therein. A fan 37 is journaled within this housing and is adapted to be rotated by the heated air entering from the interior of the lamp.

The lamp body 5 may be attached to the purifier 7 by any suitable means, such as the arms 38 and threaded ring 39.

From the foregoing description in connection with the accompanying drawings, it will be seen that I have provided a gas lamp which is so constructed as to be maintained at a relatively low temperature, which, because of its multiplicity of mirrors and lenses, Will shed a maximum amount of light, and which is visible to a certain extent from the rear.

The purifier is connected to the generator by means of the bands 40 and the latter is supported by my improved spring means. Upper and lower pairs of spaced ears 41 and 42 are mounted upon the generator 6 and are apertured to receive bolts 43 and 44. A pair of spring arms '45 is looped about each of the bolts 43 and 44. These arms are extended rearwardly and upwardly and coiled about bolts 46 carried by suitable cars 47 formed upon a split socket member 48. Sleeve members 49 encircle each air of arms to steady and hold them in proper relationship. The split. socket member is adapted to encircle any suitable support and be clamped thereto by means of the fasteners 59.

It is to be understood that while I have shown and described the preferred embodiment of my device, I do not wish to be limited to this exact construction, combination, and arrangement of parts, but may make such changes as will fall-within the spirit and scope of the invention.

It will be furthermore understood that while I have stated that my-lamp is designed especially for vehicles, it will be apparent that it may be used on hydroplanes, flyin machines speed motor boats, bicycles and or commercial use generally.

Having thus described my invention, what I claim is In a lamp of the character described, a body having a frusto-conically shaped forward portion, said body being double walled with an air space between the walls, the inner Wall being extended around tile 6X- tremity of the outer wall forming a housing, said housing being apertured upon its "rear side to admit air between the walls, the

body being formed with outlet openings at its rear to permit the escape of heated air. In testimony whereof I aflix my signature in presence of two witnesses,
