GAS-BURNER AND MEANS FOR ADMITTING GAS AND AIR THERETO.

SPECIFICATION forming part of Letters Patent No. 579,318, dated March 23, 1897. Application filed May 2S, 1896. Serial No. 592,815. (No model.)

To @ZZ whom t may concern:

Be it known that I, JOHN E. DAME, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Gas- Burners and Means for Admitting Gas and Air Thereto, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar numerals of reference indicate corresponding parts.

This invention relates to gas and air burners for stoves, furnaces, and other heating apparatus; and the object thereof is to provide an improved burner of this class and also improved means for supplying gas and air thereto; and with these and other Objects A in view the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which- Figure 1 is a plan view of my improved burner and the gas and air supply device connected therewith, and Fig. 2 is a central longitudinal vertical section thereof.

In the practice of my invention I provide a burner head or tube, which is designated by the reference-numeral 5, and which is preferably provided with a base-plate 6, which is secured thereto or formed on the bottom thereof, and said base-plate is provided with transverse supports 7, and said burner tube Y or head is preferably provided withpa longitudinal partition-plate S, which is perforated throughout its length and above which is the burner proper, which consists of the casing 9, which is also perforated throughout its length, as shown in Figs. 1 and 2, and said casing 9, which is segmental or semicircular in form in cross-section, and the partition-plate S are secured together and to thel main or body portion of the burner tube or head by bolts 10, which are passed therethrough. I also provide means for cutting out a portion of the burner tube or head when only a short part thereof is required for use, and in doing this I form in the bottom of the perforated tube or head 5 an opening 11, which is closed by a plate 12, which is of the form shown in Fig.

2, and in which is placed a cut-off or damper 13, which is mounted on a shaft 14, and between the plate 8 andthe casing 9 is placed a partition 40, and by means of this device all that portion of the burner head or tube to the right of the cut-off or damper may be closed whenever necessary and only that part thereof at the left of said cut-off or damper will be inuse.

The device for mingling the gas and the air consists of a tube 15, which communicates with one end of the burner head or tube 5, and on the other end of which is mounted an enlarged tube 1G, in the lower side of which is a slot or opening 17, and mounted on said tube 16 is a sleeve 18, which is provided at its lower side with a shoulder or projection 19; and 1 also provide a coupling-head 20, which is provided at one side with a tube 21, which communicates with the tube 16, and with the opposite side of which is connected a screwthreaded plug 22, provided with a central port, through which passes a needle valve-rod 23, which is also passed through the couplinghead 20, and which is provided at its inner end with a pointed valve 24E, which is adapted to close a similar opening in the inner end of the tube 2l, and said rod 23 is provided centrally with a iine screw-thread 25, which is adapted to operate in connection with a corresponding screw-thread in the plug 22, and mounted on the outer end of the plug 22 is a cap 26, in which is placed packing material 27.

The outer end of the rod 23 is enlarged and provided with a screw-thread, as shown at 28, and this screw-thread is the same as that formed on the central portion of said rod at 25, but of greater pitch, and mounted on said screwthreaded portion 28 is an arm 29, through the lower end of which passes a screwthreaded rod 30, which also passes through an arm 31, secured to or formed on the coupling-head 20, and the inner end thereof is con-v nected with the shoulder or projection 19 on the sleeve 18.

The outer end of the rod 23 is provided with a wheel or cross-bar 32, by whichl said rod is operated, and the cross-head 20 is provided at one side with a tubular extension 331, which is designed to serve as a suitable connection for a gas-pipe, and said cross-head is provided on its upper side with a vertical tube ICO 34, on the inner side of which is a nozzle 35, which is designed to serve as a connection for a pilot-pipe, with which a small igniting jet of gas may be carried to the burner, and the vertical tube 34 is provided with a valve-rod 36, having a knob or head 37, and the valverod 36 is adapted to control the passage through the nozzle 35.

By turning the rod 23 in one direction the passage or port at the inner end of the tube 21 will be opened, and at the same time the sleeve 18 will be moved inwardly by the rod 30 and the arm 29, thus opening the slot 17 in the bottom of the tube 16, and by turning the rod 23 in the opposite direction the port or passage in the inner end of the tube 21 will be closed, as will also the slot or opening 17, and it will be understood that the gas passes through the tube 21 into the tube 15 and that air passes through the slot or opening 17 into said tube, and said tube forms a mixing-chamber for said gas and air, and the amount of the gas and air admitted may be regulated to any desired degree of nicety by simply turning the rod 23.

This device is simple in construction and operation and perfectly adapted to accomplish the result for which it is intended, and it will be understood that my improved device for supplying gas and air may be used in connection with any desired form of burner, and that my improved burner may also be used in connection with any desired form of heating apparatus.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with a gas-burner, for stoves, furnaces and other heating apparatus, of a device for supplying gas and air thereto, consisting of a tube which communicates with one end thereof, on the outer end of which is mounted a short tube, having a slot or open. ing in one side thereof, a sleeve mounted on said short tube, and provided with a shoulder o r projection at one side thereof, a couplinghead connected with the opposite end of said short tube, and provided with a port or passage which communicates therewith, a needle valve-rod, which passes through said couplinghead, and which is adapted at its inner end to close said port or passage, said valverod being provided centrally with a screwthread, and at its outer` end with an enlarged section on which is formed a screw-thread, of greater pitch than that at the central portion of thev rod, and an arm mounted on said outer screw-thread, and connected by means of a rod, with said sliding sleeve or the shoulder or projection formed thereon, substantially as shown and described.
