' A further object of the invention is to provide a burner of the general character mentioned that .is particularly simple and inexpensive of manufacture.

.Other objects and features of the invention will be best and more fully understood from the following detailed description of a typical form and. application of the invention, throughout which description reference will be had to the accompanying drawing, in which:

Fig. 1 is a side elevation of the burner provided by this invention. Fig. .2 is an enlarged longitudinal detailed sectional view of the device, and

Fig. 3 is an enlarged transverse detailed sectional view taken as indicated by line 3-3 v on Fig. 2.

The burner provided by my present invention includes, generally, a body I0, an extension II p on the body carrying a nozzle head I2, means I3 tral longitudinal opening I5 extends completely through the body from one end to the other. The body opening I5 has portions of various diameters, as will be hereinafter described.

A lateral fuel inlet port I6 communicates with closed in the drawing the packing means for sealing about the fuel conduit includes a body I9 of packing arranged against the end of the boss I1 and surrounding the conduit I8, and a gland or follower '26 screw threaded on the boss I! to compress thep'acking. V

The body extension I I is provided to carry the nozzle head IZand to deliver or pass fuel to the nozzle head. Further, the extension II operates to support theheating means I4, as will be hereinafter described. I

In accordance with the preferred form of the invention, the extension I] is in the nature of a simple length of pipe or tubing. The extension II may be of any suitable length, depending upon the use or application of the burner. It is preferred .to initially form the extension II comparatively long so that it may be shortened team '1 desired length when the burner is installed.- It is a feature of the invention that the extension II has a detachable connection with the body III.

The outer end of the extension II is screw threaded into a socket 2| in the inner end of the body ID. The opening 22 in the extension II exstruction the'nozzle head I2 is detachably screw threaded to the extension; case illustrated in the drawing the nozzle head I2 is provided with a screw threaded socket 23 to receive the end of the extension II. The head I2 is provided with a central longitudinalopening'24 to discharge the fuel. The opening His In the particular of considerably less diameter than the opening 0 '22 of the extension, and its outer end portion 25 is restricted or reducedin diameter. The outer end portion of the nozzle opening isround in cross section and is rather short, and-its walls are flared or outwardly divergent.

The nozzle head I2 may be suitably shaped, for example, it may have an outwardly convergent exterior and a flat outer end.

The means i3 is manually operable or adjustable to control thedischarge of fuel from the nozzle [2 and operates to cause the atomization of the fuel as it is discharged from the nozzle. The control means l3 includes a fiow controlling member or control head 26, a stem 21 carrying the head 26, and means 28 for operating the stem 21. The control head 26 is disposed .within the restricted portion 25 of the nozzle opening and operates to cause the breaking up or atomizing of the fuel as it is discharged from the nozzle under pressure. The control head 26 includes a main ,portion or body 23. The body 29 of the control head is frusto-conical, having outwardly divergent walls pitched at the same angle as the walls of the nozzle opening 25. The body 29 of the control head is proportioned so that it may-effectively seat against or cooperatewith the walls .of the opening 25 under certain operating conditions.

of the control-head 26 to facilitate the mounting and removal of the control head.

The stem 21 is an elongated rod extending through the extension II and into the body I0. The stem 27 is round in cross sectional configuration and is movable longitudinally by the means 28. An end portion of the stem 2'! is slidable in the opening24 of the nozzle head. The opening 24 operates to slidably guide and center the stem. A screw threaded opening 32 is provided in the end of the stem 21 to receive the screw of the control head. The end portion of the stem 2'! extending into the nozzle opening .24 is fluted or provided with spaced longitudinal grooves 33. The grooves 33 are provided to. pass the fuel from the opening 22 of the extension .to discharge through the nozzle head. The stem 21 extends through the body opening l5 and is slidably guided and centered by a reduced portion 33 of the body "opening. It is to be noted that the

openings

24 and 33 operate to slidably support the stem 2'! at longitudinally spaced points so I that it is effectively centered and guided.

I The means 28 for operating or shifting the stem 21 includes an operating member 34 extending into an opening 35 in the body If). 'A pin 36 is provided on the operating member 34 and is screw threaded into the body opening. Asuitable hand wheel or disc-shaped enlargement 31 is provided on the outer end of the operating member 34 to facilitate the manual turning or operation of the member, The stem 21 extends through a central longitudinal opening 38 in the operating member 34. The stem 21 is freely rotatable in the opening 38. The stem .21 is connected with the operating member 34 so as to move longitudinally together with the operating member. The outer end portion of the opening 38 is of en- 40 is threaded into the outer end of the opening 38 and engages the end of the stem. 21 to retain the collar 39 against the outwardly-facing shoulder 4|. It will be apparent how operation or threading of the operating member 34 causes longitudinal movement of the stem 27. The stem 21 may not turn or rotate during operationof the member 28, as the stem is rotatably carried in the opening 38.

The invention includes means for sealing about the stem operating member 34. Packing 42 is arranged in a socket in the end of the body and surrounds the member 34. A follower 43 surrounds the member 34 and engages the packing 42. A gland or cap 44 is screw threaded onto the end of the body I0 and engages the follower 43 to force it against the packing 42.

The heating means I4 is operable to heat the fuel during its passage through the body extension ll, so that it may have the desired fluidity when discharged from the burner. Warming or heating of the fuel during its passage through the extension ll renders it more fluid, so that it is effectively broken up or atomized when discharged from the nozzle. A plurality of heating units 45 are arranged on the extension H. The

units 45 are annular or tubular structures, each including a shell 46, a heating element 41 within the shell, and suitable insulating material 48 encasing the heating element. The several heating units 45 are alike or similar in construction and are removably retained on the extension I I. There may be any suitable number of heating units 46, there being four units in the specific embodiment of the invention illustrated in the drawings. The several heating units 45 may be separate or individual devices and may be electrically connected by suitable connections 49. The heating units 45 are clamped between the inner end of the body l6 and the nozzle head l2. Spacers 50 may be arranged between the several heating units 45. It will be apparent how the heating the control head 26 may be set or adjusted to provide for the desired discharge of the fuel. The burner may be operated at pressures in the neighborhood of 2000 pounds per square inch. The operating member 28 maybe manually operated to set the control head 26 in any desired position. Where the fuel is handled at very high pressures, the body 29 of the control head may be seated against the walls of the opening 25. Theseat- 'ing of the body 29 0f the control head in the nozzle opening may be hand-tight, that is, the oper-- ating member 28 may be manually operated to seat the head 26 in the opening with the desired force. The fuel under pressure tends to stretch or elongate the control head 26 and issues from between the head 26 and the walls of the opening 25 in an extremely fine spray. It is to be understood that the control head 26 may be set in any desired or suitable position, depending upon the character of the fuel, the'pressure under which the fuel is handled, etc. The heating .units 45 operate to warm or heat the fuel during its'passage through the burner so that it is made more fluid to be readily broken up when discharged from the nozzle head I2. The burnermay be readily adapted for any particular installation, as the extension l [and the rod 21 may be cut to the desired sizes to suit theburner for any particular situation. The detachable extension I l and the stem 21 may be cut and fitted during the installation of the burner. If the extension II is shortened when the burner is installed, it is only necessary to cut threads on its end so that it may be attached to the body It). If the stem 21 is shortened, the collar 39 is fixed on the end of the stem so that the stem carries the control head 26 in the desired position. The present invention provides a burner that is particularly simple and inexpensive of manufacture and a burner that is readily capable of installation in various situations.
