BURNER HEAD AND MOUNTING.

Application. med september 1s,- 1920. serial No. 410,67sf

To all whom z't may concern.'I

Be it known 'that I, JOSEPH T. VooRHEIs, a citizen of the United States, residing at Oakland, in the county ofAlamcda and .State of California, have invented a new change which cannot be accomplished with-1 out removal of the burner. Such removal should be quickly and readily accomplished in many instances, for instance when maneuvering at sea, makinga landing or operating' under any condition where a full Y head of ste-am is necessary as the steam pressure may drop or the furnaces may become too cool, thereby causing flare-backs or other disastrous results, etc.

One of the objects of the present invention is to provide a simple and substantial burner head` and mounting therefor, which will permit changing or replacing of burners in a minimum of time and with comparatively little effort on the part of the l'iremen.

V.Another object of the invention is to provide a mechanism whereby the burner and head may be quickly removed or replaced with relation lo the mounting or support, said mechanism being readily accessible and in a position where it will not be affected by leaking or escaping hot oil.

Another object of the invention is to prothe burner is automatically closed when the burner is removed and conversely automatically opened when the burner is replaced.

Further objects will hereinafter appear.-

The invention consists of the parts and the construction, combination and arrangement of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which-- Fig. 1 is a side elevation of the burner and mounting partially in section.

- Fig. r2'fis-,an end view of the same.

Refer'ringfto the drawings in detail, A indicates alpburner tube, 2 a nozzle or' tip,

and V3 a head member to which the burner.

tube is secured as at 4.- The head member is provided with .an oil duct 5 which communicates at one end with the burner tube and at the opposite or lower end with an,

oil duct 6, which is formed in a mounting' or casting 7 provided as a support for the burner head and tube. substantially L-shaped. 1t is provided `with a handle extension 8 to permit it to be readily grasped and handled when removing or replacing the burner, and it is--otherwise provided with a seat section 9 which is.

ground to snugly engage a ground joint or seat 10 formed in the casting 7. The burner tube isenclosed or partially protected from the heat of the furnace by anexterior tube 11., This tube'is secured Vto the casting 7 by any suitable means, or as here shown by a set screw 12, the tube being secured against outward or endwise movement by. means of an annular flange 13, which also serves the4 function of centering and guiding the burner head and tube whenjreplaced; the burner head being slightly enlarged at its upper end, as at 14' to permit it to he readily centered with relation to the tube 11 when inserted. The casting 7 is other- The head member is wise. provided with an integral extension bracket 15 on the forward end of which is formed a. lug 16. This lug is drilled and threaded as at 17 to receive aclamping screw lhe inner end of this screw is slglnlyl concave and engages a centering boss 1!) forpied on the lower end of the head member-33. 'lhe screw 1S is positioned in alignment with the center portion of the ground seats il and l() and is provided with a handle 19 so that sufficient pressure may 4be exerted to form `a tight leakproof joint between the seatusections. The casting or mounting 7 is suitably supported and secured with relation to the furnace front. It is connected with a source of oil supply by means of a pipe 20; this pipe being provided with a valve 21 whereby the oil supply to the burner may be regulated.' A

It has been found in actual practice that the firemen once in a while forget to close the valve 21 when attemptine to remove the burner head and tube A. buch forgetfulness or carelessness on the part of the lire- -men has in vseveral instances proved more or less disastrous as oil under high pressure has escaped into the fire room and hasbeen lll) ignited by the fire in the furnace. VTo avoid such an accident I have provided a check valve 22. This valve-engages a seat member 23 formed in the oil duct 6y and it is provided with a cylindricalhollow exten- 'sion 24 which is engaged by theseat member 9 on the burner head. The hollow cylindrical extension 24 isv so long that it will hold the check valve 22 away from its seat when theV burner head is in position, thereby permitting oil from the duct 6 to pass between the valve and the seat and to enter the oil duct 5 in the( burner1- head through radially disposed slots 25 formed in the extension 251. The check valve is engaged by a spring 26. interposed between the valve and a nut 2T and the tension is such that the valve will instantly move forward against its seat and shut oli' the oilsupply when the burn-er head is released. It is converselyv automatically opened when the burner head is replaced as -the cylindrical hollow extension 2t is so long that it will be 4engaged by the seat section 9 and will thus force the valve rearwardly to open position when the burner head is replaced. It can therefore be seen that the danger of escaping oil or hre is entirely avoided in the present instance' regardless of whether the valve 21 is closed or not as the check valve will automatically close when the burner head is removed and will similarly assume an open position when the burner head is replaced.

ln actual practice if for any reason it is necessary to change the burner, it is'accomplished by first closing the valve 21; secondly releasing the clamping screw 18; third swinging the burner head by grasp ing the handle 8 to the dotted line position shown at. S. This causes the lower part ofthe burner head toswing out of alignment with the lug 16 and thus permits the head, the burner tube A, and the nozzle carried thereby to be retracted. `Wl1en it is desired io replace the same burner or a new burner, 1t isaccomphshed by' inserting the nozzle and tube through the exterior tube 11; the

tube and head being centered and guided` -while replacing the same by the annular' fiange 13. The moment complete insertion has been accomplished, it will only be necessary to turn'the burner head and tube to the vertical position shown in Figs. 1 and 2 and then to tighten the clamping screw and` again open the valve 21. While it is not absolutely necessary to close the valve 21, due to the provision of the check valve 22, it is obvious that it would be better practice to close the same as the oil flow would instantly start with full force unless the valve 21 is gradually opened. The annular flange 13 does not only center and guide the burner when it is reinserted, but it also serres as a pirotal point about which the This spring 1s Ahead is turned. It furthermore insures alignment of the two ground seats 9 and 10, thus insuring perfect positioningv of the same when the clam ing screw is tightened. To further insure a ignment of the ground Seats, I provide a side lug 28 and a pair of stop members 29. These stop members insure alignment of the ground seats in a lateral direction and the annular flange 13 insures alignment in a vertical direction. Iujury to the seat sections. is thus entirely avoided and alignment and centering of the same is quickly accomplished when replacing the burner.

iVhile certain features of the present invention are more or less specifically illustrated, I wish it understood that various changes in form and proportion -may be resorted to within the scope of the appended claims, similarly that the materials and finish of the several parts employed may be such as the experience and judgment of the manufacturer may dictate or varying uses may demand.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1.
