.GAS-REGULATING BUNSEN BURNER..

Patented Feb. 6, 1906.

.To all whom it may concern:

Be it known that I, CHARLES E. WIRTI-I, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented an Improvement in Gas-Regulating Bunsen Burners, of which the following is a specification.

My invention relates to a gasregulating valve device for the Bunsen burners of incandescing mantles with the object of providing a device acting in the axial center of the burner to regulate the flow of gas through a centrally-placed hole, it requiring an appreciable extent of turning movement of the burner to entirely close 0H or open up the gas-passage. In the device of my 'invention I provide a member revoluble about the nipple to be secured upon the gas-pipe. The top of the revoluble member has a central hole and the upper end of the nipple an elongated perforation, and between and at its ends passing into these parts isa valve positioned by the nipple and raised and lowered by means employed in connection with the revoluble member and returned to place by a spring. In its initial position this valve leaves the opening in the revoluble member free for the discharge of the maximum supply of gas to the burner, while in its elevated position and according to the size of the valve the opening may be entirely closed or only` opened for a minimum flow of gas, and Vbetween these positions the valve may be placed to re ulate the flow of gas as desired by turning t e revoluble member and raising` or lowering the valve.

In the drawings, Figure 1 is a vertical central section through my improved gas-regulating Bunsen burner and an elevation of the valve in its lowermost position. Fig. 2 is a vertical section and partial elevation of the operative parts of the device, showing the valve in its elevated position. Fig. 3 is a partial vertical section and elevation at the upper end of the nipple and sleeve portion of the revoluble member at right angles to the position Fig. 1, with an edge view of the valve in elevation. Fig. 4 is a plan of the parts shown in Fig. 3. Fig. 5 is a vertical section and partial elevation showing a form or modification of my invention, and Fig. 6 is a sectional plan at about the dotted line acA w of Fig. 5 with the parts in a position at right angles thereto. 4

a represents the nipple to be secured upon the end of a Uas-pipe, the same being shown heavy in the ower portion and of thinner cylindrical form in the upper portion and provided with an elongated perforation 2 in the upper end, which, as will be seen from Figs. 3 and 4, is not only elongated, but provided with opposite gas-passages.

l) is the air-distributer, c the hood, and d the Bunsen tube, which parts are of usual or well-known construction connected together substantially as shown in Fig. 1, so as to form the principal external portions of the revoluble member.

A sleeve e with a closed-in upper end extends around the upper portion ofthe nipple a, and is provided with an open center and with opposite vertically-disposed circular cams e. A cap f with a steppedexterior at its lower end surrounds thev upper end of the sleeve e and is connected thereto by an inturned rib f at its lower end, and above the upper end of the sleeve c the cap at its narrowest diameter rises an appreciable distance, and in its upper end there is a circular opening 3. Within the cap and between the same and the upper end of the nipple is located the valve, of which q represents the valve-body, and 4 opposite shoulders made therewith. 5 is the stem of the valve, 6 its conical head, and 7 its square and recessed upper end, which parts by preference are stamped up out of metal and are integral. Vithin the cap and surrounding the valve is a helical spring h, one end of which bears against the under surface of the cap and the other end upon the shoulders 4 of the valve. The valve-body g extends down into the elongated perforation 2 in the top of the nipple,

and as this perforation freely receives the valve-body it locates the valve so. that the same cannot turn, but is free to receive a vertical movement. Meanwhile the shoulders 4 extend across so that their ends rest upon the upper end of the sleeve c and come between the circular cams c. The conical head 6 when the valve is in the position Fig. 2 provides for entirely or approximately closing oil the opening 3. The square andrecessed upper end 7 normally remains in the TOO opening 3 and by the recessed construction thereof provides ample space for the discharge of the maximum flow of gas through the said opening.

In the operation of the device and considering the parts to be in the position Fig. l the connected air-distributer b, hood c, Bunsen tube d, sleeve e, and cap f are turned together. .This causes the cams e to underrun the shoulders 4 of the valve and raise the same. To obtain the full rising movement requires a quarter-turn of. the parts enumerated, at which time the" valve will be in the position Fig. 2 and according to the length of the valve, or, in other words, the proportions thereof, so the opening 3 will be entirely closed off, or so nearly so that only a minimum quantity of gas can escape-j ust enough to simply keep the mantle of the burner glowing instead of being incandescent. Between these two points the valve will be supported by said cams and will remain in Whatever position it is placed, because the valve-body cannot turn, and there is sufficient Jfriction between the sleeve e and the nipple to prevent the saine turning except by the exercise of some force.

I have shown and prefer to provide a recess in the nipple a and a rib and recess in the sleeve e, the rib thereof fitting the recess of the nipple and the recess thereof receiving the inturned rib f of the cap. Thereby the revoluble member in its entirety is connected to the nipple and longitudinal movement prevented, and at the same time a gas-tight joint is formed both during the revoluble movement of the connected parts f e b c d and when said parts are in a state of rest.

In the modification or form of my invention shown in Figs. 5 and 6, a represents the nipple provided with a circular axial opening and on opposite sides of which opening are formed circular cams e2, similar to the cams e, heretofore described, except that the cams in this instance are formed on the nipple or stationary member instead of on the revoluble member. t' represents the revoluble member of offset portions, the same being the equivalent of the sleeve e and cap f, hereinbefore described, and shown in the other figures. The upper portion of the revoluble member in the present instance is formed with parallel internal ribs t" i2, forming guides, the same being placed longitudinally of the revoluble member and on opposite sides and re ceiving between the same the ends of the shoulders 4 ofthe valve. The valve is the same as hereinbefore described, and illustrated in the other figures of the drawings, as is also the spring h, and the functions thereof in the modified form are identical. In the operation of the modification the valve turns with the revoluble member and is raised and lowered by the cams e2, being guided and also held in a fixed relation to the revoluble member by the ribs i i2. The other parts of the Bunsen burner (not shown in Fig. 5) are to be the same as shoWnin'Fig. 1. The parts a and t' are connected by a groove in aand rib 8 in fi, preventing longitudinal movement, permitting revoluble movement, and forming a gas seal.
