GAS-BURNER.

Specification of Letters Patent.

Patented Nov. 4, 1913.

Application filed April 5, 1913. Serial N04 759,106.

To all whom it may concern Be it known that we, LOUIS C. Human and 'FRANKLIN Invnve CAMP, citizens of the United States, residing at Meriden, county of New Haven, State of Connecticut, have invented an Improvement in GasBurners, of which the following is aspecification.

l he invention relates to gas burners of the type having a pilot light from which the gas is automatically ignited when turned on, and particularly to gas burners having means whereby the gas may be turned alternately oil and on by similar successive movements of a single chain or other operating device.

One object of the invention is to provide a construction in which a relatively small movement of the valve or cockwill effectively control the flow of gas in the desired manner.

Other objects of the invention are to simplify and generally improve devices of this character and to provide a self-lighting gas burner which Wlll be convenient and efficient in use and otherwise well qualified to fulfil the requirements of such a device, all as will hereinafter more fully appear.

With these and other objects in VleW we have devised the novel gas burner which we will now describe, reference being had to the accompanying drawings forming a part of this specification, and in which:

Figure 1 is an elevation, partly broken away, of a gas burner constructed in accordance with the invention; Fig. 2 is an elevation at ri ht angles to Fig. 1 with the inclosin shell removed; Fi ,3 is a section on t e line 3-3, Fig.2; ig. 4 is a section on the line 4-4, Fig. 3; Fig. 5 is an elevation of the valve operating mechanism, as viewed from the left in Figs. 2 and l, with certain parts omitted; Fig. 6 is'a detail perspective view of the operating member detached.

12 denotes a'body having a central longitudinal gas passage 13 and provided at its upper end. w th a threaded nipple 14 for the attachment of the burner proper (not shown) and at its lower end with a similar threaded nipple 15 for connection with the gas supply pipe, as bv means of a unionor threade sleeve couplin 16.

17 denotes'aninclosing shell or casing suitably held in place on the body 12, as by having a portion clamped between the union 1G and a shoulder 18 on said body. 19 denotes a passage in the body 12 leading from the main gas passage 13 below or in advance of hereinafter described, and communicating with the pilot tube.

, 20 denotes a screw constituting a valve for controlling the passage of gas to the pilot tube. Said pilot tube com rises a section 21, permanently secured within a bore 44 in the body 12, and a detachable section or pilot tube proper 22, said sections being connected by a. sleeve 23 permanently secured to the section 22 and fitting the end of the section 21,

24 denotes the main gas controlling valve or cook, said valve comprising a tapered plug held in a transverse tapered herein the body 12 by a screw 25 and Washer 26. The valve or plug 24 is arranged with its axis transverse to the axis of the gas passage 13 and at one side thereof, and is provided with a'number (preferably greater than two and herein shown as three) of communicating, radially arranged ports '27, as shown most clearly in Fig. 3, said ports forming equal angles with one another. The location of the axis of the valve 24 and the arrangcment'of the ports 27 is such that two of these ports will register simultaneously with the upper and lower portions of the gas passage 13, respectively. As shown in Fig. 3 the valve 24 is in a position to permit gas to fiow through the passage 13 to the burner. If the valve be turned through one sixth of a complete rotation the ports 27 will be moved out of register with the passage 13 and the gas will be turned off. By turning the valve through a further one sixth of a rotation communication between the ports 27 and gas passage 13 will again be established and the gas will be turned on. It will be seen that the location of the valve 24 and the arran cment of its ports is such that only one SlXlfil of a complete rotation of said valve is necessary in order to turn the the controlling valve or cook,

gas. on or oil, and that by increasing the number of ports the necessary movement of the valve at each operation may be corre spondingly decreased. It will also be ob- .served that by reason of the passage 19 in advance of the valve 24:, the flow of gas to the pilot tube, controlled by the screw er vaive 30 the reduced Uiid if Y iter-ciochm so as to (urn (iii and u; M
