BURNER.

Application iled April 11, 1925. Serial No. 22,384.

To all whom it may concern:

Be it known that I, BENJAMIN F. VALDRON, a citizen of the United States, residing at Duncan, in the county of Stephens and State of Oklahoma, have invented a new and useful Burner, of which the following is a specification.

The device which constitutes the subject matter of this application is a burner adapted to be used in boiler furnaces, or elsewhere, and the` invention aims to provide novel adjusting means, to supply novel means whereby a proper mixture will be secured, and to supply means whereby the mixture can be spread or dispersed more or less, at the will of an operator.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains, it being understood that a mechanic, working within the scope of what is claimed, may make changes, without departing` from the spirit of the invention.

In the drawings Figure 1 shows in longitudinal section, a device constructed in accordance with the invention, parts being in elevation; Figures 2, 3 and 4 are sections taken respectively on the lines 2 2, 3 3 and 4 4 of Figure 1.

The device forming' the subject matter of this application comprises a body, which as a whole, is marked by the numeral 1, the body including a casing 2 provided with a partition 8 defining a fuel chamber and a pressure chamber 5. Fuel, in the form of gas or oil, is supplied to the chamber 4 through a pipe 6, a pipe 7 serving to supply steam to the pressure chamber 5. The body 1 includes, further, a nozzle 8, the reduced end 9 of which is threaded into the casing 2, said end forming a shoulder 10 in the nozzle 8. The nozzle 8 has a large bore 11 coniinunicating with a smaller bore 12, and at the rear end of the bore 12 there is a seat 14, the nozzle, briefly stated, being connected with t-he casing 2 and communicating with the 'fuel chamber 4. In the shoulder 10 of the nozzle 8 there are any desired number of inwardly inclined air inlet ports 15.

The casing 2 has a reduced neck 16 carrying a gland 17. In the gland 17 and in the neck 16, a tubular valve 18 is slidable, the forward end 19 of the valve being so shaped that it will cooperate with the seat 14. The valve 18 slides in a gland 2O carried by the partition 3. The valve 18 has anydesired number of openings 21 communicating with the pressure chamber 5. Thevalve is supplied in its forward end with any desired number of outlet duets 22 discharging through the seat 14. A carrier 23, in the form of a rod,- is slidably supported in a way which will be pointed out hereinafter, a head 24 being mounted on the forward end of the carrier 23 and being provided with a plurality of spiral ribs 25 fitting closely but slidably in the nozzle 8, at the forward end thereof. An auxiliary fuel supply conduit 26 is assembled with the part 9 of the nozzle 8 and opens into the bore 12 to the rear of the air inlet ports 15. A valve'27, under the control of an operator, is interposed in the auxiliary fuel supply pipe 26.

The operation of the device as thus far described, is as follows y Fuel enters the chamber 4 through the pipe 6 and flows through the seat 14 and through the bores 12 and 11 of the nozzle 8, under the governance of the valve 18, which may be moved endwise, toward and away from the seat 14. Steam enters the charnber 5 through the pipe 7 and passes into the hollow valve 18 through the openings 21, the steam being discharged with great force through the ducts 22, and carrying the fuel forwardly in the nozzle 8, air being drawn in through the ports 15. The mixture, moving out of the end of the nozzle 8, will be given a whirling motion by the ribs 25 of the head 24, and the amount that the mixture is scattered, dispersed and broken up, will depend upon the position of the head 24 with respect to the end of the nozzle 8, longitudinal movement being imparted to the head by way of the carrier rod 23. If, 'for any reason, an auxiliary supply of fuel is desired, such a supply may be obtained by opening, more or less, the valve 27 in the pipe 26.

It. remains to discuss the means whereby longitudinal movement is imparted to the valve 18 and to the carrier rod 28. ln this connection, it is to be observed that a U- shaped support 28 is provided, the same including a main bar 29 provided at one end with an arm 30 terminating in a ring 31 surrounding the neck 16 of the casing 2, and held in place by a nut 82. At its rear end, the bar 29 carries a bearing 33 located about parallel to the arm 30.' Intermediate its ends, the bar 29 carries a bearing 34, similar to the bearing 33. A bearing arm 35 projects from the bar 29 and is located between the bearings 33 and 34. A bearing36 is threaded at one'end -into the valve 18, the opposite end of the bearing carrying a gland 37. rIhe carrier rod 23 slides in'the bearing 36, the gland 3"? and in the armi35. For convenience in describing the invention concisely, the bearing 36 maybe considered to bea part of the valve 13. The member 36 has ears 33 between which lOperates an eccentric 39 forming part of a foot 40 on a shaft 4l journaled in thel bearing 34, the foot 40 being held against the end of the bearing 34 by a compressionspring 42, one end of which is received in a seat 43 on the bar 29, the other end ofthe spring engaging an abutment 44 on the shaft 41, the shaft being supplied witha hand wheel-45,y or with any other' suitable means whereby it may be rotated. A glance yat Figure l will show that when the shaft 4l ,is rotated by means of the hand wheel 45, theeccentric 39, cooperating with the ears 3301i the member 36, will impart longitudinal movement to the valve 13, as and for the purpose hereinbefore set forth. n

`.A bracket- 46 is adjustable on the carrier rod 23, longitudinally,thereof, andis held in adjusted positions by a lset screw 47,r the bracket having ears 43, corresponding to the elements 33. The bearing 33- carries a mechanism 49 which, coacting with the ears 48, imparts longitudinal movement to the carrier rod 23. The mechanism indicated at 49 need not bev describedin detail, because it is a'substantial duplicate ofthe structure beginning with the eccentric 39 and ending with' the hand wheel 45.

I claim y, V j

l. In a burner of the class described, a body comprisingza casing provided with a partition defining a fuel chamber and a pressurecliamber, and a nozzle connected to admission opening communicating with the pressure chamber-,and having an outlet duct discharging through the. seat, acarrier slidable in the valve and intheinozzle, a regulatingr head on the carrier and' operating in the nozzle, means for yoperating ther Walve, and means for'operating'the carrier.

2. A device of'the'class described, constructed as set forth in claim l, and further characterized by the `fact-:that-the nozzle is supplied intermediate its end with anair inlet port, andagoverned fuel'supplyidischarging into the nozzle to the rear of the port. i

3. A device of theclass described, vconstructed asset forth in claim l, and further characterized by the'factthat oney of .the last-specified means comprises a support mounted-onthe body, a shaftjournaled in the support, and an eccentric on the' shaft.

4. A device of the class rdesc1iloed',*con structed as set forth in claim'l, and further characterized by the fact thatboth of the last-specied means comprise a support carried by the body, shafts -journal'edin the support, eccentrics on the shafts, and members wherewith the eccentrics cooperate, said members being mounted, respectively, on ythe carrier and on the valvefone'of saidmembers beingadjustable longitudinally ofthe part whcreon it is mounted,'and means for holding the said member in adjusted positions.

In testimony that I claim the foregoing as my own, I have hereto afIiXed my signature. i

BENJAMIN FRANKLIN WALDRON.
