Application filed November 11, 1916.

To all whom it may concern:

Be it known that I, HARRY A. BAUER, of Lansdowne, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Gas- Fixtures, whereof the following is a specification, reference being had to the accompanying drawings.

The invention relates to improvements in gas fixtures, and as herein shown, is incor porated in one of the types usually known as an indirect or semi-direct fixture, in which a plurality of burners are employed.

An object of the invention is to provide a valve whereby the gas supply to the various burners may be controlled so that any number may be employed at one time.

A further object is to provide a method of continuously supplying gas to the pilot burners, one of which is associated with each of the main burners, notwithstanding the various adjusted positions of the central valve.

A still further object is to provide ornamental and decorative means for concealing the protruding parts of the valve, without in any way interfering with the operation or efficiency of the fixture.

A still further object is to so proportion the parts that the structure may be readily disassembled to afford access to the various burners.

With these and other objects in view, I provide a single rotatable valve stem mounted centrally of a plurality of main burners and pilot burners. This valve stem is provided with a plurality of radial passages adapted to be brought into registry with the ports leading to the burners, by rotation of the valve stem, and a single annular groove adapted to always remain in registry with the parts leading to the pilot burners.

In the accompanying drawings, Figure I, is a sectional elevation of a gas fixture incorporating the novel features of my improvement.

Fig. II, is a detail cross sectional view on the line II, II, of Fig. I, showing the method of communication of the pilot burner tubes with the main source of gas supply.

Fig. III, is a detail cross sectional view on line III, III, of Fig. I, illustrating the controlling valve for the main burner branch pipes.

Figs. IV, V, and VI, are lllustrations similar to Fig. III, with the valve in various adjusted positions.

Specification of Letters Patent.

Patented Aug. 14, 1917.

Serial No. 130,705.

Fig. VII, shows a cross section on line VII, VII, of Fig. I.

Fig. VIII, is a development of detachable tassel adapted to conceal the end of the valve stem protruding below the fixture.

In the drawings, the usual gas supply pipe 1, is ornamented as at 2, and connected by means of a union 3, with the casing 5, of

the control valve 6. This valve is retained in its casing with provision of adjustment for wear by a cap screw 7 and washer 8, and depends downwardly in the form of a shank 9, which terminates in a flattened key 10, by which the valve may be manually operated.

A plurality of branch pipes 11, 12, and 13, are threaded to the valve casing and their outer ends are provided with the usual threaded projections15, for the support of a standard type of burner such as diagrammatically illustrated in dotted lines at 16, in Fig. I.

The branches 11, 12, and 13, communicate with the bore of the valve through ports 17,

18, and 19, respectively which in turn are 5 adapted to communicate through radial passages 21, 22, and 23, with the central duct 25, open at its upper end to the main supply pipe 1. As shown in Fig. III, the passages 21, and 22, are provided with peripheral extensions as indicated at 26, and 27. These are functional in affording a selective control of ports 17, 18, and 19, as illustrated in Figs. III, IV, V, and VI. In Fig. III, all the ports are in registry with the passages and all the branches are being supplied with gas, while in Fig. IV, the branch 13, has been cut out. Further turning of the valve in a clockwise direction results in cutting out branch 12, also as shown in Fig; V, and the final illustration of Fig. VI, shows the valve completely closed; By this arrangement either one, two or all of the burners may be employed at one time.

A pilot burner tube 30, is associated with each burner, and these are connected through nipples 31, with ports 32, of the valve casing. In the plane of these ports, the valve is provided with a peripheral groove 33, which communicates with the central duct 25, of the valve through a passage 35, as best shown in Figs. I, and II. The pilot burners, however, may be independently cut out by means of thumb screws 36, threaded in the nipples 31.

The full open and closed positions of the valve are determined by a stop pin 37,

(Fig. I), engaging a recess 38, formed at the lower end of the valve casing.

As herein shown, the fixture is adapted for indirect lighting and as is usual in this type, the burners are all located within the confines of a bowl 40. This bowl is supported, with the interposition of a resilient washer 41, by a collar 42, threaded to a tubular extension 43. Said extension is also threaded within a thimble 44, which is secured to the valve casing by suspension screws, 45, of which there are three in number. As seen in Fig. I, the thimble 44, is provided with a flange 46, through which the screws 45, pass. (See also Fig. VII.) The bowl is secured in place by means of clamp screws 47, which are provided at their lower ends with resilient collars 48, adapted to bear against the inner surface of the bowl.

The valve stem 9, passes through the cylindrical extension 43, and the dimensions of these parts are such as to provide an ample annular interspace 49, which communicates through openings 50, with the interior of the bowl and thereby affords a channel for air circulation.

By this construction the tubular extension 43, may be readily detached from the thimble and the bowl 40, removed to afford access to the burners for renewing mantles, etc. It is also to be noted that the end of the thread upon the tubular extension is cut away as at 51, inFig. I, which with a corresponding recession 52, in the internal thread of the thimble 44, greatly facilitates the assembling of parts.

In order to conceal the depending end of the valve stem, I have provided a detachable ornamental tassel 60, constructed according to the development of Fig. VIII. This tassel may be made of any suitable material, such as cording, and the strands united by a band 61, which further serves as an envelop for a spring retaining strip, indicated by the dotted lines at 62. The tassel is further provided with a thickened strip 63, which is adapted to be received between the collars 65, and 66, of the valve stem, as shown in Fig. I. After being placed into position, the tassel is secured by means of the fastening devices represented at 70, and 71, in Fig. VIII.

While the construction herein shown, provides for only three burners, I wish it understood that I do not wish to be thus limited, since the number may be varied indefinitely without involving any change in the spirit of my invention.

Having thus described my invention, I claim:

1. In a gas fixture, the combination of a valve, a plurality of burners, controlled by said valve, a depending shank for operating said valve, and a detachable tassel surrounding said shank and depending below the end thereof, whereby the shank is completely concealed.

2. In a gas fixture, the combination of a valve, a plurality of burners, controlled by said valve, a depending shank for operating said valve, and a detachable tassel surrounding said shank and depending below the end thereof, whereby the shank is completely concealed, said tassel being secured between collars upon said shank.

3. In a gas fixture, the combination of a valve, a plurality of burners, controlled by said valve, a depending shank for operating said valve and a detachable concealingtassel secured between collars upon said shank, said tassel consisting of strands of cording united by a spring band and provided with a uniting clasp.

4. In a gas fixture, the combination of a Valve, a plurality of burners controlled by said valve, a depending shank for operating said valve, a thimble attached by suspen sion screws to the casing of said valve, a.

tubular extension threaded within said thimble surrounding said shank, a light dif-' fusing bowl substantially enveloping the aforesaid elements and an adjustable collar threaded to said tubular extension, supporting said light difiusing bowl.

5. In a gas fixture, the combination of a valve; a plurality of burners controlled by said valve; a depending shank for operating said valve; a tubular extension attached to the casing of said valve surrounding said shank; a light diffusing bowl substantially enveloping the aforesaid elements; and a collar attached to said tubular extension supporting said light diffusing bowl.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, th1s sixth day of November, 1916.
