GAS-BURNER BRACKET.

SPECIFICATION forming part of Letters Patent No. 788,670, dated May 2, 1905.

Application filed January 12, 1905. Serial No. 240,815.

To all 'IJihf/TH/ it Iii/(Ly concern:

Be it known that I, ALnnn'r W. NICHOLLS, a citizen of the United States. residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Burner Brackets; and I do 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 improvements in gas-fixtures; and its main object is to provide a safety wall-bracket which when turned or swung toward the wall will lower the light to prevent it from burning the wall and at.

the same time permit it to serve as a pilotlight and which when swung at right angles to the Wall Will quickly enlarge the light witl out requiring the usual turning-key to be operated.

Another object of my invention is to provide means whereby the pilot light thus formed may be readily regulated.

A further object of my invention is to provide a device of this character which will be of simple and comparatively inexpensiveconstruction and at the same time very convenient in use and well adapted for the purpose intended.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of a wall-bracket constructed in accordance with my invention. Fig. 2 is a vertical sectional view through the same, the bracket being swung at right angles to the wall, so that the light is turned on to its full extent. Fig. 3 is a horizontal sectional view through the same, taken on the line 3 3 of Fig. 2. Fig. 4 is a view similar to Fig. 2, showing the bracket swung at right angles to its former position, parallel with the Wall, so that the light will be reduced to a very small flame. Fig. 5 is a horizontal sectional view taken on the line 5 5 of Fig. 4. Fig. 6 is an elevation of a portion of the bracketarm having the regulating-plug. Fig. 7 is a vertical sectional view showing a slight modification of the invention, the pilot-light-adjusting screw being located at the top of the bracket instead of at the bottom, as seen in Fig. 2; and Fig. 8 is a view similar to Fig. 7, showing the pilot-light-adjusting screw at one side of the plug of the bracket-arn'i.

Referring to the drawings by numeral, 1 denotes the usual bracket-casing, which has one of its ends 2 adapted to be screwed upon a stationary gas-pipe and its opposite end formed with two conical seats 3 4, connected by a gas-inlct 5. The seat 3 is adapted to're ceive the usual cut-off plug or cock 6, having an operating-key 7, and the seat 4 is adapted to receive the plug 8, which is provided upon the bracket-arm 9 and which serves as a pivot or fulcrum for the latter. In carrying out my invention I form in the periphery of said plug 8, in alinement with the gas-inlet 5 of the casing 1, two non-communieating grooves or channels 10 and 11. The latter extends approximately three-fourths of the way around the periphery of the plug 8 and the former less than one-fourth, so that the remaining portions 12 of the plug separate saidgrooves when the plug is in its seat 4. The usual centrally-disposed gas-duct 13 in the plug 8 and its bracket-arm 9 are placed in communication with the said grooves or channels 10 and 11 by means of channels or passages 14 and 15. The passage 14, which I will term the L main-burner passage, leads from the groove 10, as clearly shown in Fig. 2, so that when the bracket 9 is turned in the position at right angles to the wall the gas may pass freely through the inlet 5, the passage 14, and the duct or passage 13 in the plug 8, and bracket 9. The passage 15, which I will term the pilot-light passage, is. as shown in Fig. 2, substantially right-angular in form, one of its arms or branches 16 extending transversely and effecting communication between the groove 11 and the vertically-extending arm or branch 17, which is screw-threaded, as shown at 18. This branch 17 is screw-threaded to receive an adjusting or regulating screw 18, which passes upwardly through the bottom of the plug 8, as shown, the latter being retained in its seat 4: in the casing 1 by the usual washer 19 and nut 20. It will be seen that by means of the screw 18 the passage of gas through the pilot-light passage 01' channel 16 may be readily regulated to vary the size of the pilot-light as desired. In Figs. 7 and 8 of the drawings the location of this screw 18 is slightly different. In Fig. 7 it passes downwardly through a threaded opening 21, formed in the top of the bracket, and projects into the said vertical portion 17 of the pilot-light passage 15. In Fig. 8 this pilot-light passage 17 is angularly disposed, as shown at 22, and the regulating-screw 23 passes through a transversely-extending screw-threaded opening 24, formed in the plug, as shown.

The operation and advantages of my invention will be readily understood. It will be seen upon reference to Figs. 2 and3 that when the bracket-arm 9 extends at right angles to the wall the groove 11 will be closed and the groove 10 in communication with the inletpassage 5, so that the gas may pass freely to the bracketarm 9. and that upon reference to Figs. 4: and 5, which show the bracket-arm swung parallel to the wall, the groove 10 will be closed and the groove 11 in communication with the passage 5 to permit the gas to pass through the pilot-light passage 15 and into the bracket-arm 9.- By adjusting the regulating-screw the size of the pilot-light may be readily varied as desired.

When this invention is used, therewill be little or no danger of burning the wall when the bracket is swung around.

While I have shown and described the preferred embodiments of my invention, it will be understood that I do not wish to be limited to the precise construction herein set forth, since various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is r 1. In a gas-bracket. the combination with a casing having a gas-inlet, of a bracket-arm having a pivot-plug seated in said casing, said plug being formed with non-communicating peripheral grooves or channels, a centrallyextending duct, and passages leading from said peripheral grooves to said central duct, whereby, when the said bracket-arm is turned in one direction, the inlet in said casing will be in communication with the central duct of said plug through one of said passages and the peripheral groove or channel of such passage, and, when turned at right angles to said position, the inlet in said casing will be in communication with the central duct of said plug through the other of said passages and the peripheral groove or channel of the latter, substantially as described.

2. A gas-bracket having a pivot for the bracket to swing on as its fulcrum, and provided with a duct extending centrally in said pivot and'having two entrances or passages leading to opposite points in the periphery of said pivot, said entrances or passages being in communication with non-communicating peripheral grooves or channels formed in the said pivot, and means for controlling the flow of gas through one of said entrances or passages, substantially as described.

3. A gas-bracket having a pivot for the bracket to swing on as its fulcrum, and provided with a duct extending centrally in said pivot and having two-entrances or passages leading to opposite points in the periphery of said pivot, said entrances or passages being in communication with non-communicating peripheral grooves or channels formed in the said pivot, and a screw for controlling the flow of gas through one of said entrances or passages, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ALBERT WV. NICHOLLS.
