BROILER.

Specification of Letters Patent. Application filed March 25, 1909.

Patented June 1, 1909. Seria1 No. 485,566.

To all whom it may concern.'

Be it known that l, Louis Fav, a citizen oi' the United the county of' Hamilton and State oi Ohio, have invented certain new and useful lmprovements in Broilers, of' which the following is a specification. My invention relates to burners, and its object is to provide an arrangement oi'l burners l'or using gaseous iuel in broiling meats and the like by placing the articles to be broiled over the burners, thereby utilizing the i'ull amount of heat produced, and at the same time to avoid ignition ci' the grease or juices lfrom the articles broiled, and avoid the clogging of the burner orifices.

My invention consists in the combination with a burner having orifices for the escape and combustion ol gaseous l'uel, oi' a shield or hood mounted on the burner, having arches over said orifices through which the i'iames ol" combustion may pass from the orifices, but by means of' which fluid matter is carried below the burner without ignition.

My invention also consists in the parts and in the construction and arrangement of' parts as will hereinafter be described.

ln the drawings: Figure l is a front elevation oi' a device embodying my invention. Fig. 2 is a horizontal cross section on the line r oi' Fig. l. Fig. 3 is a vertical cross section on a line corresponding to the line g/*g/ oiI Fig. l, extending from the iront to the rear oi' the device. Fig. 4 is a vertical cross section on a line corresponding to the line .a-z ol' Fig. 2, illustrating, however', a modification oi' the use oi' the device. Figs. 5 and 6 are, respectively, a plan view and a side elevation of' part ol' the hood. F 7 is a vertical cross section through the hood on the line a-a of Fig. 6. Fig. 8 is a cross section on the line b-b oi' F ig. 6. Fig. 9 is a section longitudinally of the hood through one of the arches on a line corresponding to the line c-c ol` 5. Fig. 10 is a similar sece tion on a line corresponding to the line d d of Fig. 5. Fig. i] is a vertical section through a hood and a burner longitudinally thereof', illustrating a modification of' the burner to receive the hood, parts being broken away for lack oi` space. F ig. l2 is a similar section, through part ofl ahood and burner formed integral. F ig. 13 is a side ele.- vation of a hood in which wires are used for legs, parts being broken away for lack of' space. Fig. 14 illustrates the operation ci' States, residing at Cincinnati, in l y the mass of the y cessively heated,

,i form of a series of other lengthwise of the two l'orms oi' legs shown, in conducting liquid.

As illustrated in the drawings, the broiler consists in a casing l, provided interiorly with ledges 2, on opposite sides, running horizontally from its front to its rear, on which may be supported, at various heights, a broiler grating 3, which is adapted to receive meats or other articles to be broiled. Below the grating 3 are the burners 4L, each consisting in a tube closed at one end by a cap 5 and communicating through its other end with a mixer of suitable construction, which receives the gas through a pipe 7 provided with a valve 8 for controlling the flow of the gas to the burner. A main valve 9 controls the flow of gas to all the burners. These tubes forming the burners 4 extend transversely of the casing, at, preferably, regular intervals, and areprovided with orifices l0 at regular intervals throughout the greater part of their lengths, the orifices being located on both sides and extending radially through the walls of the tubes at angles suitable to direct the iiames upward against the lower side of the articles being broiled, in the most effective manner.

Resting on the tube is the shield or hood consisting in a series ci arches l1, each of which is so positioned that one of the orifices l0 will be located within it. At the same time, the hood, thus made up of the arches, straddles the tube and thus rests thereon in such position that the tops of the arches are maintained a considerable distance above the upper side of the tube, and the hood is otherwise so proportioned that the flames coming from the orifices 10 may pass upwardly, as above stated, through the arches without being obstructed thereby. The tops of the arches, which form the greater part of hood or shield, by this construction, are also prevented from being exe owing to the fact that none of the flames strike them directly, thus adding to the lasting qualities of the device. Owing to the construction of the hood in the arches succeeding each the. tube and straddling the tube, the part of the hood between each arch on each side will form a leg 12. Each of these legs l2 is provided with a vertically extending groove, or gutter 13, and laterally downwardly sloping gutters 14 are provided between the arches, on the top of the hood, communicating with these vertically extending gutters 13. The top of each arch j is inclined from a middle horizontal ridge 15, j in both directions to these gutters 14 between the arches. 1t will thus be seen that j the top of the arch over the orifice in the 1 burner, extending in a horizontal direction, l will not be adapted to conduct the grease over the side of the hood at the top of the arch, but all liquids will be conducted into j the gutters 14 and from there into the gutj ters 13 in the legs 12 between the orifices and between the flames which escape therefrom. 1n addition to being thus constructed, the 1 hoods are so positioned that adjacent ones will be out of alinement to the extent of one- 1 half the width of one of the arches so that the flame passing from the orifices in one j burner will pass diagonally upward and over the gutters 13 and 14 of the adjacent hood. l Thus, ample space is allowed for the passage l of the flames to avoid interference as hereinbefore referred to.

As preferred, the hoods are formed sepaj rately from the burners and secured thereon i by means of nuts 16 screwed onto the tube of j the burner at the ends, clamping the hood j between them. 1t will be seen that the position of each hood on its respective burner may be adjusted by screwing the nuts forward or backward on the tube. 1n order to j maintain the hood positively in upright position on the tubular burner, 1 prefer to proj vide the burner with lugs 17 near its ends i which are adapted to enter corresponding l recesses 18 in the lower sides of the arches at l the ends of the hood. vWhere adjustment of the hood longitudinally of the burner is not l considered essential, the burner may be j formed with hubs 19 at its ends adjacent to which it is provided with lugs 17'l adapted to enter recesses 18 in the hood, as above described.

1n the modification illustrated in Fig. 12 of the drawings, the construction is similar to the above described construction excepting that the hood is formed integral with the burner tube.

1n the modification illustrated in Fig. 13, the hood consists in a body forming the top thereof and having the gutters 14 and ridges 15, but having the legs formed of wires 12a. l 1n such a construction the grease or juices must follow the wires instead of the gutters 13 in the legs 12. 1V here legs 12 with gutters 13 are provided, the grease will follow the gutters 13 as indicated at m in Fig. 14, while when wires 1:2a are used for the legs, the liquid will follow the wires as indicated at n in Fig. 14. 1t will be seen that with the gutters the surface of the grease is less exposed to the action of the heat than where wires are used.

TWith any of the above constructions, it will be seen that the orices are protected from the contact of the grease or juices therewith, avoiding the possibilityv of clogging the orifices and interfering with the operation of the burner. 1t the same time, these greases or juices, being confined to particular paths, are prevented from coming into such proximity of the iiaines as would cause their ignition. rihus, it is rendered possible to broil the articles by placing them over the burners without interfering with the operation of the burners or burning the products obtained from the articles broiled, which may be saved and which are valuable. The preferred construction, as iirst described, is

j particularly advantageous since it allows the hood or shield to be removed from the burner proper, permitting the burner, as well as the hood or shield, to be thoroughly cleaned. T he advantages attendant upon broiling the articles over the burners instead of under them, as is generally practiced, will be obvious, since, in attempting to direct the heat downward onto the articles, as ordinarily, most of the heat is wasted.

As illustrated in Fig. 4, it will be seen that the size of the broiler may be increased to any as a unit, using these units in any desired number, placing them one after the other, with their ends abutting, along the burner tube, and clamping them in position thereon in the usual manner. rlhus, as shown in Fig. 4, the burner is long enough to receive two of the hoods thereon, allowing the broiling space of the broiler to be practically twice the extent of that of the broiler illustrated in Fig. 1 of the drawings. 1t will be noted that the arches constituting the hood are not only arched over the orifices of the burner but are arched over the burner transversely thereof so that the tops of the arches afford the most efficient means for conducting the grease laterally of the burner and down past the sides thereof, but the bottoms or interior parts of the arches of the hood are separate from the burner tube far enough to a'flord ample air space between these parts of the hood and the adjacent parts of the tube to avoid undue heating of the hood as hereinbefore referred to. 1n addition to thus affording insulation of the hood from the burner, such a construction renders the hood less liable to warp under the action of the heat, since it substantially consists in a series of concavo-convex shells integral with each other, these shells being concave and convex both transversely of the hood and longitudinally thereof.

As illustrated in Fig. 1, the casing 1 may be provided with a shelf 2() upon which articles may be placed for warming, thus utilizing the heat that escapes upward past the broiler grating. 1n this connection it may be noted that whereas in the broiler with the burners over the broilerI grating most of the desired extent with the use of the hood y heat will naturally be directed upward instead of onto the article to be broiled so that a shelf, such as the shelf 20, over such a broiler would receive most of the heat, in my improved broiler only such heat as escapes past the articles being' broiled will be communicated to the warming shelf, utilizing' most of the heat for broiling, which is the object sought to be attained by any broiler.
