HORIZONTAL LIGHT.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed November 5, 1906. Serial No. 342,111.

To aZZ whom it may concern.-

Be it known that I, ADOLPH G. KAUFMAN,

, a citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful Horizontal Light, of which the following is a specification.

This invention relates to incandescent gas burners, and has for its object to provide a burner of this character in which the mantle will be held in a horizontal, or inclined, plane, so that it will have the advantages of the drop, or inverted light including throwing the light directly down without the shadow of the burner being interposed, and will have certain advantages over the inverted light to be hereinafter pointed out. Further objects of my invention being, first, to provide means to hold the mantle in a horizontal, or inclined position in a secure and firm manner; second, to provide means to distribute the gas flame in an even manner over the mantle; third, to provide means for the easy regulation of the flow of gas; fourth, to provide a suitable globe; and, fifth, to provide an improved globe holder and flame and heat shield.

My invention is illustrated in the accompanying drawing, in which- Figure 1, is a side elevation of a horizontal light constructed according to my invention, the globe being in section; Fig. 2, is a plan view of the mantle holder; Fig. 3, is a view of a modified. form of my invention; Fig. 4, is a bottom plan view of a modified form of the discharge nozzle, with the inclosing mantle Fig. 5, is a side elevation thereof; Fig. 6, is a side elevation of another modified form; Fig. 7, is a plan view of the gas regulator; and, Fig. 8, is a vertical section thereof.

In the accompanying drawing the several parts of my invention are indicated by numerals of reference; and in practice I provide a light in which, as shown in Fig. l, the mantle 9, is held in a horizontal position, the gas discharge nozzle 10, being also in a horizontal position. The discharge nozzle 10, is larger than the column, or pillar 11 as clearly shown in the drawing, and is provided with a plurality of perforations 12, part of which are on the under side, as shown, so that when the gas and air is discharged into the mantle the flame will be distributed in an even manner over the entire surface thereof, and without waste of gas, as usually occurs where the mantle is inverted, for the reason that no gas escapes from the mantle without performing its function, and less pressure is required to force the flame against every part of the mantle.

The mantle 9 is mounted on the usual supporting ring 13, having feet 141; but in order to hold the mantle firmly in position, I provide the holding spider 15, with a plurality of humps 16, corresponding in number to the legs 14, of the ring 13, and proportioned in height so that when the angular portions of the legs 14 are in engagement with the humps, as shown in the drawing, the ring 13 will be drawn firmly against the spokes 17, of the spider, thereby holding the mantle 9 firmly 1n position.

Instead of holding the mantle in a horizontal position, as shown in Fig. 1, it may be held in an inclined position, as, for instance, in the manner shown in Fig. 3 the pillar 11, being curved so that the mantle is held in an inclined, downwardly directed position; but it is evident that the inclination might be reversed, or made at a difl'erent angle without preventing the downward radiation of light, and without permitting the escape .of flame from the base of the mantle, the mantle being in substantially a horizontal position.

While the gas flame will be evenly distributed by the form of nozzle shown in Fig. 1, I may provide a different form of nozzle, as shown in Figs. 4, and 5, in which the perforations 12 are all on the sides and bottom. As the gas flame will naturally flow upward, by forcing it against the sides and bottom of the mantle, the entire mantle will be reachedby the flame, as will be readily understood. Instead of using the form of nozzle shown in Figs. 4, and 5, I may use the form shown at 10, in Fig. 6, by which the flame will be driven downwardly and outwardly.

To provide for the easy regulation of the flow of gas, I have provided the improved gas regulator shown in Figs. 7, and S. This regulator consists of a .nipple 18, having a thimble-shaped extension 19, which is slotted transversely at right angles, the slots 20, extending to the base of the extension, as shown in Fig. 8, and the slots are made of sufficient width to allow of the [low of considerable gas through thcm. The nipple is also provided with a casing 21, which is pro vidcd with a screw-tlneaded portion 22, which may be screwed into the air mixer 23. I also provide a sleeve 24, which is screwed upon the nipple 18 and has a reduced extension 25, with an opening 26, in the end thereof; and the extension 25 is so shaped internally that when the sleeve 24 is screwed tightly upon the nipple 18, the four sections of the thimble-shaped extension 19, will be drawn into contact with each other at the edges, as indicated in dotted lines in Fig. 7, and by providing a gasket 27, to prevent the escape of the gas from the bottom of the slots 20, the flow of the gas will be entirely cut off and the regulation is such that a partial turn backward will open the slots to their full extent; so that by mounting a handle 28, in the sleeve 24, and providing the casing 21, with a slot 29, the flow of gas can be shut oil by bringing the handle into the position shown in dotted lines in Fig. 7, while intermediate of these points the flow of gas will be regulated as desired, as will be readily understood.

WVith this form of light, a globe of special construction is necessary, and accordingly I have provided a globe 30, which may be secured to the globe holder 31, by screws 32; and has an open top 33, an opening in the side of the bottom thereof 34, and a slot 35, extending from the opening 33, to the holder 31, the slot being of suflicient width to allow the passage of any flame which might escape from the base of the mantle through improper adjustment, and also to prevent the uneven heating of the globe by the heat accending from the base of the mantle.- The opening 34 being at one side of the bottom, will allow the admission of air, but is sufficiently far from the center to prevent the falling of any debris from the mantle to the floor, especially while hot.

The globe holder 31, comprises the annular flange 36, forming the seat for the globe, a

shield 37, ending in a ring 39, which fits upon the air mixer 23; and intervening between the globe seat 36, and the shield 37, is an annular portion 38, having a plurality of air holes 40. By this construction should the pressure be great enough to drive the flame out at the base of the mantle, the shield 37 will prevent the flame reaching the air mixer 23, and igniting the gas therein, and this shield will also prevent the overheating of this air mixer. Should the flame strike the shield, the air holes being in the annular part 38, the flame will be directed outwardly away from the air mixer, thus avoiding all danger of ignition of the gas in the mixer. It will thus be seenthat this part not only serves to hold the globe in position; but is quite an essential feature for this form of light.

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