OIL BURNER.
Application led January 25, 1923.
To all lwhom t may concern.'
Be it known that I, CHARLES H. SIMMONS, a citizen ofthe United States, and resident of Chicago, 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.
My invention relates to burners, and relates more particularly to those using liquid fuel, such as oil, in which the latter is subdivided or carburetted under the action of centrifugal force.
One object of the invention is the employment of an electric-driven motor which may be operated at moderate speed, and hence may be produced or -manufactured relatively economically, a further aim' of the invention being to lubricate the gearing employed by the oil later used in and consumed at' the burner, and to this end the gears may be submerged in the supply of I such oil.
To the accomplishment of these and other desirable ends, I' 'have provided the preferred embodimentof the invention present'- ed in detail in the accompanyingdrawings forming a part of this specification and throughoutthe several views of which like reference characters have been used for the same parts. f
In these drawings,-
Fig.A 1 is a partial elevation and artial central longitudinal section through t e improved burner showing it. in place in the lower portion of a furnace;
Fig. 2 is an enlarged partialelevation and partial section on line 2 2 of Fig. 5, showing the screw pump mechanism for feeding the oil;
Fig. 3 is a horizontal section on line 3 3 of Fig. l;
Fig. 1 is a horizontal section'on line 4-4 of Fig. l: and Y Fig. 5 is a plan View and partial section of the portion of the structure shown in Fig. 2, but on a' reduced scale.
By referencel to the drawings, it will be seen that the improved and 'novel appliance includes a base 11 a portion of which iS intended to be positioned inside of the lower portion of the furnace 12,. the other part of the base projecting forwardly out of the Y Serial No. 614,749.
nected to a suitable source of liquid fuel supply,-Such as oil, not shown, by a pipe 17 which projects inside of the chamber and is equipped internally o f such chamber with a suitable valve structure 18 through which the oil is delivered into the compartment and which is operated/(by an arm 19 on a lever 21 fulcrumed at 22 on one wallof the chamber, such lever at its other end carrying a float 23 whereby the oil or other liquid 1n the compartment is automatically maintained at a substantially predetermined level.'
An upright skeleton standard or frame 24 mounted on the floor or bottom wall of the `compartment has roller bearings 25 and 26- for a revoluble, vertically-disposed, hollow shaft 27 which extends' upwardly out through a hole in the cover plate.
The open lower end of such hollow shaft is fitted with a screw pump element 28 secured to the shaft internally at such end and projecting down beyond thebottom of the shaft nearly to the base of the compartment.
As lis shown most clearly in Fig. 2, Such screw or spirally-formed member is enclosed in a cylindrical shell 29 reaching from the bottom wall of the compartment, to which it is secured in any approved manner, to the under face of that cross part 31 of the standard fitted with the lower rollerbearing 26, the bottom portion of the shell having ,a. number of apertures 32 therethrough to permit. the oil to flow into its interior.
The hollow shaft' 27 is equipped with a spiral-gear 33 driven by another spiral-gear 34 on a suitably-journaled, horizontal shaft loo oil inthe compartment isI such that these intermeshing, co-operating gears 33 and 34 for the admission of air to its .interior.
a set-screw 44.
The pipe inside of the element 37 has au number of spirally-arranged, oil-delivery holes 42 which may be opened or closed more or less by an adjustable collar or sleeve 43 held on the shaft in adjusted position by A plu 45 fits in the open top endof the shaft and carries a horizontal, circular plate 46 with a beveled edge` spaced vertically above the similarly beveled top edge o f the member 37 to provide a circular slit or opening throu h which the mixed oil and air are discharged under the action of centrifugal force ready for combustion, the additional oxygen for which is supplied by the surrounding air.
In order to admit air to the oil compartment 14 to facilitate the pumping of the oil to the rapidly-rotating distributor 37, its
-cover is supplied with one or more' vent ver holes 47.
A circular support 48 of suitable shape spaced away from and surrounding the burner elementn 37 carries an inclined re fractory wall 49 sloping. downwardly inwardly toward the burner, the appliance being fitted with a pair of appropriate pilot lights or burners 51 and 52. j The structure operates practically as follows:
l The motor, removed' or positioned away from the hot zone, rotates at-a moderate speed, for example, 1750 R. P. M., and through the gears 34, 33, it revolves the burner at high speed. The oil in the bottom of the compartment or chamber flows into the shell through the apertures of the latter and is pumped up the hollow shaft by the screw or spiral member 28, being discharged laterally therefrom by centrifugal force through the shaft ports 42, where it becomes mixed with air entering the apertures 41, the mixture being delivered through the circular opening between the parts- 37 and 46, and being consumed in a whirlin flame after such exit.
Any excess of oi or any delivery thereof when the 'pilotlights are not burning by accident, fiows down the wall 49 and returns to the oil compartment through the holes in its top wall.
It will be perceived that although the burner is rotated at a relatively high speed, the motor which does the work revolves at a much slower speed, the increase in speed being due to intervening gearing properly lubricated by reason of its immersion in the oil supply, the oil from the latter being gradually drawn ofi for combustion purposes.
The invention is not limited and restricted to the precise and exact details of structure herein presented, but it is susceptible, of a variety of satisfactory embodiments, all differing more or less in mechanical. details, but all incorpora-ting the main or fundamental principles constituting the essence of the present invention as defined by the appended claims'.
