EDWIN E. HILLIKER, OF EAST AURORA, NEW YORK.
LIQUID-FUEL BURNER.
Specification of Letters Patent. Patented Jjflyi 27', 192() Application filed August 29, 1918, Serial No. 251,881. Renewed June 8, 1920. Serial No. 387,513.
To all whom it may concern Be it known that I, EDWIN E. HILLIKER, a citizen of theUnited States, residing in East Aurora, in the county of Erie and State of New York, have invented new and useful Improvements in Liquid-Fuel Burners, of which the following is a specification.
This invention relates to a liquid fuel burner which is more particularly designed for producing heat in a stove by the use of kerosene oil although the same may also be used for other heating purposes and in connection with other kinds of liquid fuel.
It is the object of this invention to produce a burner of this character which is very simple in construction, capable of being produced at low cost, not liable to get out of order, readily inspected, cleaned or repaired and one which will produce a maximum heating effect for the amount of fuel consumed and not liable to back fire or interfere with the proper burning of the combustible mixture after the same has burned for some time.
In the accompanying drawings:
Figure 1 is.a side elevation of the liquid fuel burner embodying my improvements. Fig. 2 is a sectional top plan view thereof with the top plate or cover removed. Fig. 3
is a vertical longitudinal section taken on line 33, Fig. 2. Fig. 4 is a vertical cross section of the same taken on line 44, Fig. 2.
Similar characters of reference refer to like parts throughout the several views.
In its general organization this burner comprises a longitudinal mixing chamber 1 into the front or outer end of which the vaporized liquid and air are introduced so ing coil 4 preferably of U-shape which has one leg arranged adjacent to the burning surface of one delivery chamber and another leg arranged adjacent to the other delivery chamber, one end of this pipe having a supply-controlling valve 5 and connected with a liquid supply such as a kerosene oil tank while the opposite end of this I through which the heated liquidis dischargedinto the outer or inlet end of the mixing chamber.
In carrying the chambers-of this invention into practical form the same are preferably constructed as follows:
7 represents horizontal bottom plate or floor provided on its upper side with two longitudinal inner walls 8,8 which are arranged parallel but spaced apart and which have their front ends in line with the front or outer end of the bottom plate'while their inneror rear ends terminate short from the rear end of thebottom plate, two longitudinal outer walls 9, ,9 arranged along'opposite longitudinal edges of the bottom plate, a curved rear wall 10 arranged along the' curved rear end of the bottom plate, and two. transverse walls 11,11 each of which is arranged at the front end of the bottom plate and connects the corresponding front and said walls being preferably constructed integrally of cast iron.
' 12 represents a top plate or cover which extends over the upper edges of the walls and is provided on its underside with grooves or channels 13. which receive the upper edges of these walls so as to'form' a comparatively tight joint therewith. This I cover or top plate maybe connected with the bottom plate and associated parts in any suitable manner, for instance, by'meansof screws 14: bearing with their headed ends against the outer side of the top plate while their threaded ends engage" with correspondingly threaded openings in the bottom plate, as best shown in Fig. 3. By'this means the inlet or mixing chamber is formed 'between the inner longitudinal wallsand the adjacent parts of the top plate and bottom plate and each of thedelivery or outlet chambers is formed between one' of the inner longitudinal walls and the companion outer longitudinal wallsand the adjacent parts of the top andbottom plates.
Each of the delivery chambers is provided with a longitudinal burner opening 15 arranged in the outer longitudinal wall of this chamber and extending to the top.
plate so that the latter serves to complete. the burner opening for the respective delivery chamber. The burning surface in this burner opening is preferably construct ed in the form of a screen which isheld in place by engaging its lower horizontal edge with a lower channel or groove 16 formed in the lower edge of the burner be easily put in place when assembling. the
parts as well as readily removedtherefrorn when wornout and replaced by another, so that it is possible to maintain the burner con'venientlyin its best working condition.
The U-shaped heating pipe is preferably so mounted on the outer'side of the delivery chambers that the same is readily detachable therefrom, for which purpose a plurality of pairs of retaining lugs 19,-19 are provided the members of each pair being arranged one above the other, and one pair .being arranged at the front ends of the longitudinal outer walls and another pair centrally on, the outer side of the curved rear wall. The U-shaped heating pipe is preferably so constructed that in order to engage its legs and curved bow .with the pairs of retaining lugs; on the outer longitudinal'walls and the curved rear wall, it is necessary to spring the legs of this heating plpe apart somewhat, and after the bow and legs of this pipe have been engaged with the several pairs of-retaining lugs, as
shown in the drawings, the resilience of this pipe operates to hold the same reliably in place without requiring any additional fastening means, thereby reducing the cost of manufacture. accordingly and 'materially simplifying the construction. the heating. pipe are preferably arranged lengthwise along the outer sides of the outer longitudinal walls so that the tops of these legs are adjacent to the lower edges 'of the burner openings and burning surfaces, whereby the flames upon issuing from these burning surfaces will play against the upper sides of these heating pipe legs and heat the contents thereof.
It follows from this construction, that when kerosene oil or other liquid hydrocarbon or fuel is supplied throughthe inlet end of the heating pipe, that the same passes successively through the legs of the heating coil and is exposed to the flames issuing from the "burning surfafl: whereby this liquid is raised in temperature and caused to issue from the delivery valve in a vapor condition. ,This vapor is delivered into the filont or inlet end of the mixing chamber and carries with it continuous stream of airinto the mixing chamber.
sage through the mixing chamber become and an upper groove 18 formed hori-.
The legs of 7 thoroughly commingled, so as to form a combustible mixture in which all parts are thoroughly mixed and in the best condition for subsequent combustion. Upon reaching tlierear end of the mixing chamber this combustible mixture strikes the curved rear \wall'and is divided into two streams which are caused to travel in a direction opposite to that in which the mixturemoves through the mixing chamber, one of thesestreams passing reversely and'forw'ardly through one of the delivery chambers and the other reversely and forwardly through the other delivery chamber. As the mixture in each dehvery chamber reaches the outlet opening of the latter, the same issues in the form of a finely divided body through the screen therein and burns on the outer side of the latter which forms the burning surface. The flames issuing from these burning surfaces pass upwardly as'well as laterally for heating any object which may be above or at the side of the burner, and part of these flames are engaged with or are sufficiently closeto the upper sides of the heating pipe legs to vaporize the kerosene oil within the.
latter. 7 r
Bythis means a thorough preheating or vaporization of the kerosene oil or other liquid fuel is effected before it is delivered into the mixing chamber, a large and ample volume of air is drawn into the mixing chamber with the vaporized fuel, and a free outlet for the combustible mixture is formed on opposite longitudinal sides ofthe burner so as to furnish the maximum heat for the quantity of fuel which is consumed.
Owing to the flames of this burner being on opposite longitudinal sides thereof and fresh air being continuously drawn through the central part of the same, there is a constant tendency to keep the central part of the burner cool, so that overheating of the same and backfiring which would follow such overheating, is prevented. V
' Furthermore, this tamer is very compact and simple in construction, it has compara tively few parts, most of which can be cast of metal at low cost without requiring any coring or expensive machine work for fitting them together. Moreover, ing the heating coil so'that thesame is only exposed to a part of the flames, it is possible to obtain the requisite vaporization of the] liquid without unduly heating this pipe which otherwise would cause the same to be burned out and necessitate frequent freby arrangthe opposite end of the mixing chamber and ing an outlet opening toward said inlet of the mixing chamber.
