UNITED STATES OIL. IB

Application filed February To all whom it mag concern Be it known that I, FRANKS. E'enorr, a citizen of the United States, residing at Riverside, in the county of Cook and State of Illinois, have invented certain new and useful Improvements "in ,Oil Burners, of which the following is a specification This invention which relates to an oil burner is designed particularly for use with building heating'plants of various kinds. In its construction are embodied numerous features of improvement having to do with simplicity in the construction and assembly. of its several components, and with general accessibility or removability of its princ pal units for purposes of repair, replacgment,

. burner showing the interrelation of its several components; and.

Fig. 2 is a plan view thereof with the flame andring deflectors removed.

The presentburner comprises four ma'or -unitsa burnerl'iead A- whereon is rest-e a flame deflector B, a frame C in which the burner ,head. is mounted, and a ring D ,loosely carried; in the frame. These several parts, when assembled as shown in Fig.- 1, are adapted to be placed within a" furnace wherein pipe connections are also carried to supply or remove oil as required.

The burner head is in the general form of a hollow cone having an inner cylindrical wall 3 uniting with a. bottom A which, in turn, is united with the lower, edge of an outer cone wall 5 having its -upper edge terminating, by preference, slightly below the upper edge of the cylindrical wallB. Between the upper edge of the cone wall 5 and the cylindrical wall 3 is an opening 6, shown as annular, communicating with the chamber 7 which is formed interiorly of the burner head by the walls and bottom just described. A fuel inlet pipe 8 is connected definitely advantageous FRANK S. EGLOFF, OF RIVERSIDE, ILLINOIS.

with the bidder head'so as to into this chamber.

deliverfoll The conical wall of the burner-head is are formed a plurality of cam-shaped ribs '1'2, constituting in effect a multiple cam.

.A drain pipe 13 connects with the trough,

.as shown. An undercut shoulder 14 is-fur- -ther formed on the peripheral wall, 'and incomplementary relation thereto are certain webs 15 projecting.inwardly from .the frame C. This frame which is of plate-likestructure provides through themedium of its several webs aseat inwhich theburner head is rested, a plurality of arc-shaped openings 16 having a substantial area intervening therebetween. Each of these webs, as shown.

is provided-with a lug 17 adapted to engage '80 i with the under side of the shoulder-14 to thereby afford support for the burner head-i.

By rotating the head to the position shown in Fig. 2 the cam ribs, will be caused to engage with certain grooves 18 that are provided in the webs so as to interlock the head with the. frame. Manifestly the head may- 'be removed "after being turned in a reverse direction sufliciently to disengage the cam ribs from thewebs of the frame. I

An upstanding shoulder 19 is provided on the frame in such a manner as to form an annular seat"whereon the ring D may be ,loosely rest-ed. The walls of this ring, ac-

For convenience in handling, an eye 23 is provided on-the upper w I side of the deflector, as shown. An e11 burner answering to the above ,de-

scription possesses certain very definitead- 1 p I J Supported on the burner head is the flame vantages both from the standpoints of manafactureand assembly, and of operation; as well, its several parts may be readily 1nstallod within a furnace, the frame alone.

being fixedly secured in place therewithin.

Adjacent the out-er periphery of the frame I have provided several elongated arcuate slots 24: through which, at any point'intermediate of their ends, one or more attaching bolts (not shown) may. be inserted for securing purposes. Manifestly the ring D may be lifted o'fi'of its seat without any preliminary operation. whenever its removal is desire Likewise the flamedefiector maybe taken off of the burner head by asimilar'operation. By first unlocking the burner'h'ead through a rotary 1noti0n, it may be removed' from'. the frame, either through 1ts upper or lower' side. .Incarrying out this latter operation, it is contemplated that the two oil pipes should be disconnected, preferably at the union (not. shown) which, in ordinary prac'' tice, is located close. to the. furnace door.

The present burner may use advantageous' lyany suitable distillate Whose gravity range is, say, from 36 to 42 degrees Bau'm. The chamber 7 is filled from the supply pipe so that the oil thereinmay burn at 'the opening 6, the oil burning' at that point only; producing the minimum. amount of flame and heat. WVith i crease in the flow. of oil to the burner, a portion of the fuel which overflows upon the relativelysteep conical walls 5 will spread and breakup, thelighter partbeing consumed before; reaching the base of the cone; vthe flow of the heavier portion of the fuel is retarded atthe shoulder of the cone, being consumed at thatpoint or above sofas to produce the maximum amount of flame'and heat, the flame being spread in a desirable manner by meansofthe deflector- B.

In case any valve controlling the flow. of oil through the intake pipe is opened accidentally or otherwise, so as to allow oil to.

flow through the burner without being ignited,,or in case of an excess of-oilbemgfed to the burner, any such excess or overflow is collected at the trough 10- from -whence it flows through the'o'utlet pipei13 into a cup (not shown) which may operate :a drip valve for shutting o'fl the, oil passing through the supply pipe.
