Feb. 25, 1936 W. C. STOLLBERG OVERFLOW DEVICE Filed Oct. 20, 1933 Di Hin OOO OOOO

Patented Feb. 25, 1936 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to devices for preventing the overflow of fuel oil in the burner well of a gaseous fuel burner and it primarily has for its objects to provide a device for that purpose which will be of a simple, eiiective and inexpensive construction, one which will be non-siphoning and one which will not give ofi objectionable odors.

Further, it is an object of my invention to pro vide a device for the purpose stated in which provision is made whereby the over-flow pipe of the device may be closed off when it is desired to prime the burner.

Further, it is an object to provide an over-flow device of the character stated in which the level of the over-flow tubes outlet may be adjusted higher or lower in order that the fuel level in the burner well may be raised or lowered.

Further, it is an object to provide an over-flow device in which air vapors, which may be formed due to excessive heat, may be condensed in the device and run out through an over-flow discharge pipe.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, the invention still further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description, and then be particularly pointed out in the appended claims, reference being had to the accompanying drawing in which:-

Figure 1 is a vertical section of a burner with my invention applied.

Figure 2 is an enlarged vertical section of a slightly modified construction of my device.

Figure 3 is a top plan view of the parts shown in Figure 2.

Figure 4 is a cross section on the line 4-4 of Figure 1.

Figure 5 is a vertical section of another modification of the invention.

In the drawing in which like numerals and letters of reference designate like parts in all of the figures, i represents the oil well of the burner (the burner may be of any well-known construction), 2 the oil chamber housing, 3 the float valve, 4 the lower sediment chamber into which the fuel oil is delivered and from which it passes via the float valve 3 into the sediment chamber 1 of the housing 2. The housing 2 has a duct 8 that communicates with the burner-well oil-feed tube 9 that is secured in the oil chamber housing by means of a compression sleeve ll and compression sleeve lock screw [0.

i2 is the sediment chamber head through which the needle valve unit 5 passes for controlling the flow of fuel oil into the chamber 1. Secured to the head 5?. in any suitable manner is a duct is which has a base I4 that carries the. outer casing 15 of my device. The casing 55 encloses an overflow chamber 3'! and it has an inlet bore It in which is vertically adjustably mounted the overflow pipe ii. The pipe l? is held in its position by means of a compression sleeve 18 and compression sleeve lock screw [9. The head l2 which carries the duct l3, etc. is held in place by the valve head 39 which is threaded at 40 to screw into the threaded part 4! of the well 2; 4'6 indicates the float-valve stem guide, 41 the valve stem, 42 the float bar, 43 the float connecting rod from the bar 42 to the float 44, the latter being located in the float chamber 45. The operation of the

parts

3, 41, 42, 43, 44 and 45 may be the same as those of the

respective parts

8, 9, l, B, 5, ,5

In order to prevent siphoning the casing 15 may be provided with one or more vents 22.

In the embodiment of the invention shown in Figure 1 the upper end of the casing I5 is internally threaded as at 23 to receive a screw plug 24 which has a tapered shut-off member 25 that may be used to plug the upper end of the overflow pipe I! when it is desired to prime the burner. The plug 24 is provided with a screw driver slot 25 for manipulation purposes.

21 is a slot for a wrench whereby the compression lock-screw I9 may be turned.

Instead of screwing the plug 24 into the casing [5 the arrangement shown in Figure 2 may be employed. In Figure 2 those parts which cor respond to like parts in Figure I bear the same reference numeral plus the index letter a. The plug 24a is not threaded into the casing l5a, but is slidably mounted thereon so that it may be forced toward the upper end of the pipe Ila by pressing on the finger knob or button 28 against the tension of a light spring 29. The plug 24a is held from movement out of the casing l5a by means of a threaded collar 30 which has holes 3| for a spanner wrench. By this arrangement it is impossible to close the end of the the button 28 the spring 29 will force the plug 2 1a awav' from the pipe Ila. 1 Z

In 'fFigure Zjthe casing |5a is shown connected withfa duct 33 that communicates with the ioil feed line and the burner-well oil-feed tribe through the tuse of ordinary pipe fittings and couplings not shown. The'duct 33 is connected with the casing Ilia by means of a threaded collar 32 which corresponds to the base I; while the duct 33 corresponds to the duct l3 in'Figur'e 1.

In Figure 5 is shown another modification of the invention? In this figure the over-flow pipe 11b is threaded at 35 into t le. base [4b and the casing I5!) is removably threaded into the base, the casing lSb having openings 38 in its threaded end to register with the oven-flow pipe 2lb that is carried by an over-flow neck 35 of the base [4b. In this embodiment also the casing IE1) is provided with the tapered plug 25b so that by unscrewing thecasing Gib and inverting it as shown in dotted lines in Figure 5 it may be used as a temporary closure fer the pipe llb when it is desired to prime theburner.

In the embodiment shown in Figure 5 those parts which correspond in purpose and function to like parts in the preceding figures bear the same reference numeral plus the index letter 19.

The oil level is indicated in Figure 1 by line 36.

From the foregoing description, taken in connection with the accompanying drawing, is thought that the complete construction, arrangemerit and advantages of my invention wili be clear to the art to which it appertains.

What I claim is: a V

lfIn combination with a liquid frgel burner, a constant maximum level fuel fee-ding means 4O therefor including a housing having an inlet compaiftment communicating with the source ofi fuel, a sediment compartment communicating j with theburnery a threaded passage connectingsaid compartments, a detachable cover plate forming a wall of said sediment compartment and having an upwardly extending conduit pro ecting therefrom in communication with the sediment chamher and an opening in axial alignmjent with said threaded passage, a valve unit extending through said opening and into engagement with 'said threaded passage to contrgrl the flow of fuel between said compartments and to clamp said cover plate in place, and an overflow device connected to said conduit and operatlvely positioned relative to said burner to prevent flooding thereof wall of said sediment compartment and havinglan upwardly extending conduit projecting therefrom in. communication with the sediment chamber'and an opening in axial alignment with said threaded passage, a valve unit extending through saidppening and into engagement with said threaded passage to control the flow of fuel between said compartments and to clamp said coverpiate'in place, an overflcw' device connected to said conduit and operatively positicnedrelative to, said burner to prevent flooding thereoi upon the fuel level exceeding said maximum level, and manu aiiy actuated means for endering said'overfiow device inoperative purposes.
