i VAPOR-BURNER.

SPECIFICATION forming part of Letters :Eat-.ent No. 251,709, dated January 3, 1882.

Application inea september 3o, 18st. (No model.)

To all whomy it mail concern:

Be it known` that I, EZRA O. GARLAND, ot' New Bedford, county of Bristol, and State of Massachusetts, have invented an Improvement in Vapor-Burners, ot' which the following description, in connection with the accompanying drawings, is a specilicat-ion.

My invention relates to vapor-burners for hydrocarbon fluids.

In burners ofl this class as heretofore commonly constructed the liquid passes through a suitable passage to a small orice, Where it is ignited, the said fluid being converted to a vapor by the heat ofthe parts after the llame has been burning a short time. This orifice is usually controlled by a needle-valve mounted on a screw-threaded stem, so that by rotating the said stem the point of the needle is caused to move through the orifices for the purposeV of clearing it when it becomes clogged or for partly closing it to control the effective area ofthe orifice and consequent size of the iiame. By this arrangement a considerable rotary movement of' the valve-stem is required to produce an effective lon gitndinal movement of the point of the valve, and the process of clearing the orifice ofthe burner is consequently a slow one.

This invention has for its object to give the needle-valve a direct reciprocating movement, and at the same time to enable it to be Xed in any desired position so as to properly regulate the passage of the fluid. The needlevalve is mounted in a carrying-block, which is guided b v and free to slide in a tubular passage, and an operating-handleis properly connected therewith to give the said block and connected valve the desired sliding movement.

A clamp is provided by which the said operating-handle and connected valve may be tXed in any desired position to control thepassage of the liuid, and thereby regulate the flame.

Figure l is a vertical section ot' vapor-burner constructed in accordance with my invention; Fig. 2, an elevation thereof, as viewed from the right-hand side of' Fig. l, the socket of the operating-handle being shown in section; Fig. 3, asection on line :v a', Fig. 2, illustrating the holding-clamp for regulating the burner; and Fig. 4, a side elevation ot' the i valve and its carrying-block detached.

The. burner a, with its inlet-passage b and orifice c, may he of any usual construction.

Below the burner and in line with the passage leading directly to the orifice is a tubular guide,d, which receives a block, e, carrying the needle-valve f, adapted to clear and control the orifice c, the said valve-carryin g block c being of suitable material to slide easily in the guide-tube d. The said guide-tube d is provided with a tubular projection, g, extending laterally from the part occupied by the block ewhen in an intermedia-te position. The socket hl for the valveoperating spindle t' projects laterally from the projection g, and is screw-threaded internally.

The valve-operating spindle t' is shown as a threaded rod having a portion, j, bent at an angle to the threaded spindle to serve as a handle to enable the latter to be easily rotated. The said spindle t' is so connected with the block e that a slight 'rotary movement ot' the said spindlewill produce a longitudinal movement of the needlej' toward or from the orifice c, which may thus be thoroughly cleared by a slight oscillation of the handle j. As herein shown, the block e is provided with a notch or hole, 2, and the handle t' is provided. near its end with a hole, 3, which, when the said handle is in place in its socket, as shown in Fig. 2, lies within the tubular projection g and opposite the said notch 2. A pin, l, is passed through the hole 3 and enters the notch or hole 2, as shown in Fig. l, the end ofthe projection g being left open to enable this pin to he inserted. When the parts are thus properly put together by screwing the spindle into its socket and inserting the pin l the end of the projection g is closed by a screw-plug, m, which serves also to retain the pin l in proper position.

The end of the handle-socket h is `split on one side, as shown ata-4, Fig.3, to form a clamp, which is operated by the thumb-screw a to tightly hold the handled and fix the point of the valve f in any desired position to properly regulate 'the flame.

The handle t is screw-threaded for4 the purpose of packing, asits longitudinal movement is immaterial; and it will he seen that by making the valve containing tube and handlesocket in a single piece, as herein shown, the

TOO

burner is as tight at every point as when .provided With the usual threaded stemmed valve.

I claim- 1. The guide-tube, lateral projection therefrom, and handle-socket extending laterally from the said projection, all made of a single piece, combined with the needle-valve and its carrying-block fitted in the said guide-tube, and the valve-operating handle mounted in the said socket, and connected with the said block, to operate it and the connected valve, substantially as described.

2. The guide-tube, tubular projeclion there from, and handle-socket, combined with the valve and itspslotted or notched carrying-block and the handled spindle, and pin mounted therein and entering the slot ofthe valve-carryin g block, substantially as described.

3. The reciprocating needle-valve and its carrying-block, and the valve-operating handle connected with the said block, combined with the handle-socket slotted and pivoted with 'a clamping-screw to fix the said handle and valve in any desired position, substantially as described.

4. The valve and guide tnbe and lateral tubular projection therefrom and the handlesocket, combined with the valve operating handled spindle and pin to connect it with the said valve, and the screw-plug to close the end of the said tubular projection and retain the said pin in proper position, substantially as described.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.

EZRA 0. GARLAND.
