GAS-REGULATI'NG MEANS.

SPECIFICATION forming part of Letters Patent No. 733,954, dated July 21, 1903.

Application filed April 91 1903. Serial No. 151,890. (No model.)

the extreme point of exit, so that the force of discharge will not be seriously interfered with.

In view of the fact that gas varies in pressure it is desirable to vary the discharge-orifice to suit such differences. The original manner of accomplishing this was to ream the opening; but if it was the least bit too large or too small the candle-power was re duced. ployed for changing the size of the dischargeorifices; but those which to my knowledge have proven practicable and have been placed generally on the market either require the services of an expert to operate them or else are comparatively expensive to manufacture.

It is the object in the present invention to provide an extremely-simple device for regulating the pressure, which device can be cheaply manufactured and readily and properly operated by any one of ordinary intelligence. v

The device, furthermore, because of its quick-action qualities is useful for turning down the light without extinguishing it entirely, thereby acting in the nature of a bypass.

The preferred means for accomplishing these objects is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of the invention, the parts being shown on an enlarged scale in order to more clearly illustrate them. Fig. 2 is longitudinal sectional view through the same. Fig. 3 is a cross-sectional view. Fig. 4 is a detail perspective View of the valve, and Fig. 5 is a view in elevation of the holding-cap.

Various devices have lately been em-' the valve.

Similar reference-numerals indicate corresponding'parts in all the figures ot' the drawings.

In the embodiment herewith illustrated a suitable conduit or body 10 is employed, having a passage-way 11 therethrough. The lower end of the conduit is counterbored and internally threaded, as shown at 12, to permit its attachment to a gas-bracket in the ordinary manner. The upper end of the conduit is formed into a nipple l3,the passage-way therefrom being contracted, as shown at 14, and constituting a valve-sear.

A valve is slidably mounted in the passageway and comprises a head 15, carrying a needle 16, which is movable into the dischargeorifice. The head is preferably angular in crosssection, and a socket 17 extends int-o the same from one face, the inner end of the socket being rounded and the outer portion thereof being outwardly flared, as shown in Figs. 2 and 3. The wall of the conduit is provided with an opening 18 therethrough that alines with the socket l7, and the outer portion of this opening is enlarged and rounded to form a socket. employed in the structure, said lever extending through the opening 18 and having an intermediate enlarged ball 20, that fits in the socket portion of said opening. The inner end of this lever is also provided with a ball enlargement 21, which fits on the socket 17 of The lever is held in placeby a cap-plate 22, having a bifurcation 23 and a circular recess 24, in which the outer portion of the intermediate ball 20 of the lever fits.

The cap-plate is held in place by a fastening screw 25, that engages the conduit and serves to clamp said plate against the ball 20, so as to constitute friction holding means for the lever and urge the ball 20 thereof into close engagement with the walls of the socket in order to prevent the escape of gas.-

The operation of this regulator will-.be apparent. When the handle end off'the lever is raised, the needle will be correspondingly lowered, and the discharge-orifice may thus be opened to any degree desiredqf The plate 22 serves as a frictional holding'device, so that the valve will remain in any position.

drawn through the opening, as the inner ballis smaller than the same. It will be apparent that the structure can be manufactured at very small cost, and the parts are not liable to become deranged. The valve can be operated, if desired, for turning down the light, and the needle may be constructed so as to afford a small passage-way for the gas when itisin closed position, thus acting as a by-pass.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without fnrtherdescription, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the ad vantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In gas-regulating means, the combination with a conduit having a valve-seat therein, of a valve movable toward and from the seat, and an actuating-lever fulcrumed in one wall of the conduit and having a connection with the valve for moving the same.

2. In gas-regulating means, the combination with a conduit having a valve-seat therein, of a valve movable toward and from the seat, and an actuating-lever mounted on the conduit and having a movable engagement at its inner end with the valve.

3. In gas-regulating means, the combination with a conduit having a socket in its wall and a valve-seat, of a valve coacting with the seat, and a lever having a ball that fits in the socket, said lever also having a connection with the valve.

4. In gas-regulating means, the combination with a conduit having an opening therethrough, the outer portion of the opening being enlarged to form a socket, of a valve-seat located in the conduit, a valve coacting with the seat, and a lever passing through the conduit-opening and having an intermediate enlargement located in the socket, the inner portion of said lever being connected to the valve.

5. In gas-regulating means, the combination with a conduit having an opening therethrough, the outer portion of the opening being enlarged to form a socket, of a valve-seat arranged Within the conduit, a valve coacting with the seat, a leverpassing through the conduit-opening and having an intermediate ball enlargement fitted in the socket, the inner portion of said lever being connected with the valve, and a cap fitted over the ball and secured to the conduit.

6. In gas-regulating means, the combina' tion with a conduit having a valve-seat, of a valve coacting with the seat and provided with a socket, and an actuating'lever having its inner end movably engaged in the socket.

7. In gas-regulating means, the combination with a conduit having a valve-seat, of a valve coacting with the seat and provided with a socket, and an actuating-lever having aball at its inner end that movably fits in the socket.

8. In gas-regulating means, the combination with a conduit having a nipple and a valve-seat located therein, said conduit being provided with an opening therethrough the outer portion of which is enlarged to form a socket, of a valve slidably mounted in the socket and movable toward and from the seat, and a lever having a ball enlargement on its end and on an intermediate portion, the end enlargement fitting in the socket of the valve, and the intermediate enlargement being located in the socket of the conduit.

9. In gas-regulating means, the combination with a conduit having a valve-seat, of a valve coasting with the seat, a lever movably mounted on the conduit and arranged to actuate the valve, and holding means for the lever frictionally engaging the same.

10. In gas-regulating means, the combination with a conduit having a valve-seat and a socket, of a valve coacting with the seat, an actuating-lever for moving the valve, said lever having an enlargement fulcrumed in the socket, and means for holding the enlargement in the socket.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

EDWIN E. FREDERICK.
