ROBERT G. KIRKWOOD, FI PITTSBURG, PENNSYLVANIA.
.To all whom it may concern.
Be it known that l, llonsa'r lr. Kiimwoon, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented. ce1- tain new and useful Improvements in (.)il-
4 l'hilrner Stands, of which the following is a specification, reference being had therein to `the aeeomlimnying drawing.
My invention relates to improvements in liquid or gaseous fuel` burners, and especially to certain novel means for supporting and operating such a burner.
The :in'iproved supporting stand or frame and operating meehanifan is especially in tended for use in. connection with open `hearth steel meltin T furnaces. lIn manv instances'this class of furnaces .is fired by two liiurncrs, using a burner Iat opposite `ends of the furnace alternately, and as the heated gas from the operating burner passes ofi at the opposite end of the furnace, it is necessary to Withdraw the nozzle of the idle bui-nea.' from the mouth of the furnace to prevent melting off of the same from the g: of the operating burner.
Theobject of the present invention is to provide i'ueans for supporting such a burner as indicated above, which will supply fuel, such as oil and air to the burner, and at the same time provide the burner with movements to intrtuluce, or withdraw the nozzle of the burner from the furnace in Which the fuel. is to be used.
A. further object is to provide means by which the point or nozzle of the burner-.niay be elevated or depressed as desired for use in the furnace'.
The inventionconsists in certain novel features of constructioi'i in the supporting frame; a pivoled hurner; regulating valves on the air and oil inlets, and-"certain comhi` nations and arrangements of parts as hereinafter set forth.
ln the present descril'ition ofthe device Il` `shall reifer to the use of oil and air as the i-.xai'i'ipleof the physical embodiment'of my' invention, constructed according vto the hec* Specicatien of Letters Patent. Application filed August 6, 1906. Serial No. 329,326.

22, 29, castings, bored to receiveV the oil and4 air pipes, and provided with pairs ofsset screws 30, by means of which screws vthe pipes are held rigid with relation to their castings 29; 3l, 31', the inner ends of the supply pipes 27 and 28 which ends are located within the extensions 23 of casting 21 32, 32, packing glands at the joint between pipes 27 ,and 28 and 'their respective extensions 23, 23,33, 33, threaded nuts to engage 'the threaded extensions 23 to force the packing into the packing space to form an oil and air tight joint at the connections; 84, an air cylinder, preferably formed -of brass tubing and provided with -heads35, each having a pair of perforated projecting lugs-36; 87, 37, a pair of suspending bars, each having a journaled end 38 adapted to swing on the studV shaft 20, and their outer threaded ends passed through the perforated lugsA 36 on the air cylinder; 39, 39 shoulders formed on the bars 37, located adjacent the cylinder head 36, and adapted to bear rthereon; 40, 40, nuts on the threaded ends of the bars 37, by means of which, in connection' with the shoulders 89, the two heads 36 may be clamped withan air tight joint to the cylinder 34; 4l, an air inlet pipe or tube passed throu fh an opening in the lower head of the cylinder 34, and forming a stationary piston rod; 42, a piston located in the cylinder and secured by screw threads at the endI of the air pipe 41; 4?, a packing ring; 44, a -packing nut; 45, a i'netallic casting provided with a journaled extension 46, an interiorly threaded extension 47, and exterior threaded extension 48, and a cord passage 49 which connects with the open ends of theY extensions 47 and 4:8; 50, a supporting casting'in which the'journal 46 has a bearing; 51 acompressed air supply pipe; 52, a seat formed 1n the bore of the casting 45 to receive the en d of the pipe 51;r 53, a packing gland inclosed by the extension 48 and surrounding the pipe 51; 54, a packingy nut,
sin'iilar lo the nuts 8S on the supporting frame, for securing an air tight joint between the pipes il4 and 5l g' 55, a supporting A casting through which thc pipe 5l is passed and secured rigidly therein by means of the set screw .Soy 57 `a sheave, loosely journaled by means or' its hub on the shaft 20; 59, a bar or extension of the hub 58; 60, an adjustable weight connected to said bar; 61, a
l cord or rope having one end -firfmly secured at (52 to the sheave 57 and. passed over said sheave, and (Sil is a suitable anchor for the rope or cord f VThe stand or supporting [frame for the burner is arranged to receive oil from supply pipe 27 andl con|pres:-;cd air from pipe 28 and eonjvey these elements of `the fuel through pipes'6 and 7, trunnion arms 2 and 3 and burner 1 and from the nozzle thereof the fuel passes into the furnace.
The hollow trunnion arms 2 and 3 have bearings in the castings or caps 4, and the oil burner maybe elevated or depressed as desired on these trunnions as a pivot point. The bearings between the ends of the trunnion arms 2 and 3 and the openings in the castings 4 are ground to make la 'tight oil` and air joint so that when the nut 17 on -bolt 16, and the screw bar 14 are tight the trunnion of theburner is held between the castings 4, 4, and the joints are oil and air tight, but the joint also permits Ithe burner to be oscillated in order to depress or .elevate the nozzle thereof as desired It will be observed that the-valves 10 and 12 will' be operativel at all times to regulate `t-he inlet of oil and air, regardless of the position of.
The sha-ft 20 is rigidy and does notV rotate, v
except when turned by a wrench or otherv toolto adjust the distance between 4the pipes 6 and 7. The height of the shaft maybe fixed by means of the set screws 19 which clamp the cross couplings 18 rigid withthe a upright pipes.
The supporting frame, carrying with'it the burnerf is adapted to swing on the journal 22 as a center to introduce the burnerto, or withdraw it from the furnace. The oil sup-- ply pipe 27 andthe air supply pipe 28 re-- main stationary, but when the frame is Afoscillated to move the burner the extensions 23 and their packed joints revolve around the ends of the respective pipes as a support, the main support for the swinging movement however, being the ycasting 26 in which the journal 22 rotates. 'lhe drawings illustrate one example of a desirable'J form of joint, vthe essential feature being that the frameshall swing, but at all times be in communication with the supply pi es; vl Various ways may be adapted fiir use-in s winging the frame to introduce the burner tov or withdraw the same from the furnace. ln the accompanying drawings I employ mechanism operated by the same air pressure which feeds the oil to the burner and furnace. to the supporting frame I provide the airor steam cylinder having a movable orswinging piston, to which is connected a hol-lowv piston rod which forms the air inlet, pipe to the cylinder. is connected to a rotatable casting in manner similar' to the `connection between thesupp'orling frame and its supply pipes.
One end of the piston rod To give the swinging movement ,l
thereon provided with a Weightedarm and the sheave is connected by rope 6l to the anchor G3. By opening valve 64, the 1notive pressure formoving the frame to position to introduce the burner into the furnace, and for supplyingjr the feed of air to the vfurnace, is turned on sinnlltaneously, and hy closing the valve the pressure is diseontirn'led.
l'Vhen the burner is to be intri'idueed to the furnace, 'alve (it. is opened and cornpressed air passes through pipe 7 to the bnrne' as described; the air also passes into theeylinder from pipe 5l, casting 45- and pipe 41. The cylinder is forced away from the piston, (the cylinder swingingr on the shaft 2()v as a center and the piston ro'd swinging on journal 4(5) and the rods 3T push or force the supporting frame in a wringing motion with the journal 2ias a center. The rope G1 fastened to the anchor and being fast to the sheave, causes the shea ve to turn on the stud shaft, lifting the weight G0 toward ahorizontal position, until the frame Carrying the burner reaches the desired position with relationto the furnace which the burner is to tire. The oil or other fuel being turned on, the fire is regulated by means of the valves 10 and 12. When it is desired-to withdraw the burner from the furnace, the oil is turned od and valve 64 is closed, allowing the pressure te escape from the cylinder through burner pipe 7. The weight 6() falls winding the rope around the sheave until the weiehted arm assumes the posit-ion shown in Fig. 1. A further drop of the weight to vertical poi sition causes the supporting frame to pass beyond its upright position, and its own 0 weight serves to carry it beyond the uprigl'it position to an inclined position away from the furnace, thus withdrawing the burnerV from the heated furnace.
