ELECTRIC BROILER.

SPECIFICATION forming part of Letters Patent No. 585,308, dated June 29, 1897.

Application filed OOtOlJGI 28, 1896- Serial N0. 610,275- (N0 model.)

To all whom it may concern:

Be it known that I, GEORGE E. FRALEY, a citizen of the United States, residing in the city of Denver, in the county of Arapahoe,

' State of Colorado, have invented a new and useful Improvement in Electric Broilers, which improvement is fully set forth in the following specification and accompanying d rawi n gs.

My invention consists of a novel construc* tion of electric broiler in which the meats, viands, or other articles to be cooked, heated, or broiled are effectively subjected to heat from a source of electrical enegy, provision being made for rotating the broiler and enabling the juices which are usually lost in the act of broiling to be effectively retained within the article which is being broiled.

It further consists of a novel construction of conductive blocks through which the electricity is conveyed while the apparatus is in operation.

It further consists of novel means for gaining access to the interior and for enabling the broiler to be rotated without retarding the operation thereof.

' It further consists of novel details of construction, all as will be hereinafter set forth, and specifically pointed out in the claims.

Figure 1 represents a side elevation of an electric broiler embodying my invention. Fig. 2 represents a plan view of the broiler, the standard and its adjuncts being broken away. Fig. 3 represents a front View of the broiler seen in Fig. 1. Fig. at represents a perspective view of the receptacle in which the meats, &c., to be broiled are placed. Fig. 5 represents an interior plan view of one of the heating-blocks, showing the conductor for the electricity. Figs. 6, 7, 8, and E) represent modified forms of heating-blocks which may be employed. Fig. 10 represents a perspective view of an oven for heating and working, showing the means for electrically heating the same and a drip-pan in which the juices from the viands cooked are received. Fig. 11 represents a detail View showing the manner of making the connections from the exterior to and through the hollow shaft on which the principal operative parts of the broiler are mounted.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a suitable base, and B a hollow standard arising therefrom upon which the broiler O is adapted to be supported.

D designates a shaft which is supported in suitable bearings, in the present instance near the top of said standard, said shaft having a hand-wheel A mounted thereon,which latter may be provided with a handle, if desired.

E and F designate collars or commutators mounted on the shaft D, as seen in Fig. 11,

E in Fig. 1, and it being of course under-- stood that said strips are supported in any suitable manner within the hollow shell G at the top of the standard B, in which the shaft D has its bearing.

L designates a wire or conductor leading from the commutator E through the hollow shaft D and out through the port M to the binding-post or terminal N, which is located in the heating device P, the same consisting, in the present instance, of a series of blocks Q, which are held together by means of the bolts R or similar devices.

S designates a conductor of electricity which is sinuous in form, as will be evident from Figs. 2 and 5, said conductor being formed by grooving or recessing the blocks assembled, as shown, to the desired depth and painting the same with a composition of plumbago or carbon, which is pulverized and commingled through the medium of any suitable saccharine material, the said conducting device S leading to the terminal T, from which the wire U leads back to the port M, into the hollow shaft D, and thence by conductor V to the commutator F, and thence through the strip H to the conductor K, out and away from the broiler, the course of the current being understood from Figs. 1, 2, and 5 and the dia grammatic view seen in Fig. 11, the parts omitted from one figure for the sake of clearness of illustration being shown in the others.

The grooves or recesses in the blocks (seen in Fig. are usually, in practice, painted every time the broiler is used with the composition of plumbago or carbon and saccharine material above referred to.

\V designates a conductor leading from the conductor L into the external circuit, which is designated by X of the diagrammatic view in Fig. 11, it being understood that said circuit X represents the lower heating-block of a broiler in case the circuit S is designed to represent the upper block, as will be apparent, the current passing to and through the circuit X, through the wire \V, and being thence conducted to the wire V and through the com mutator F and strip H to the conductor K and out of the broiler.

l3 designates a skeleton casing or oven, (best seen in Fig. 4-,) within which the meats or other articles to be cooked are placed, said even consisting of the front side 0, the rear side D, which is provided with the boss D which is adapted to be screwed into engagement with the hollow shaft D, as will be evident from Fig. 11, the oven having the ends E, which are shown in the present instance as closed or solid.

and G designate wires or other devices having their ends attached to suitable supports, said wires being adapted to be bowed inwardly, as indicated in Figs. 1, 3, and -l, and to support thereupon the gridiron upon which the meats or other articles are to be broiled.

ll designates latches, (best seen in Figs. 1 and 3,) which are pivotally attached to the sides E and have hooks J thereon, which are adapted to engage the pins K, which are inserted in the heating blocks or devices P, the movement of said latches 11 being limited by the pins 31, and the position of said latches relative to said pins being assured by means of the springs L.

N designates lugs attached to the ends of the heating-blocks P for the purpose of readily manipulating the latter, which, it will be understood, are hinged or pivotally attached to a suitable support, which may be the easing B, through the medium of suitable lugs and the pins B P designates a modified form of heatingbloek, (seen in Fig. 7,) in which are supported the sections Q, R, and S, which are held together by means of bolts T or other suitable devices, said sections when assembled being provided with sinuous grooves l which extend intermediate the terminals U V, said grooves being filled with carbonized paper, silk, or other suitable analogous conducting material.

X designates a modified form of heatingblock, as seen in Fig. 6, and similar in some respects to the block seen in Fig. 7, except that the several elements of the conductors C extend in substantially parallel lines to each other, the several blocks of which the heating device proper is composed being held together by means of bolts \V, and the conductor C being provided with the terminals A B D designates another manner of mounting or securing the conductor of the heatingblock, (best seen in Fig. 8,) said conductor being designated as F and having a depending portion H and being struck up from a plate of metal or other suitable conductive material. In like manner the block E (seen in Fig. 9) has its conductorembedded therein in an analogous manner, said conductor consisting of the strip G which has the depending legs IF attach ed thereto, the current passing through the strip G and by reason of the resistance of the latter heating the same to a high degree, and consequently the contiguous blocks between which said strip is held.

The function of the legs ll is to assist in the retention of the strip G in place, it being of course understood that in practice the top of the strip G preferably terminates near or projects slightly beyond the top of the adjacent blocks and that a plurality of strips and blocks are employed, which latter may be arranged substantially as seen in Figs. 5 and 6, if desired.

In Fig. 10 is seen another embodiment of the principle of myinvention, J designating an oven which has a top K a base L and the sides P said top having embedded therein a suitable conductor R which has the terminals Q and S into and through which the electricity is conveyed for the purpose of heating said top, which latter may be of fire-brick or other suitable material and being thus readily heated to a high degree.

The meats or other articles to be cooked may be placed on suitable skeleton frames or other devices, which are supported on the lugs M it being of course understood that as many of the latter may be employed as desired.

N designates a pan for the reception of the drippings from the meats or other viands while they are being cooked.

The operation is as follows: The meats or other articles to be cooked having been placed in position between the wires F G, the heating blocks or devices P are brought against the top and bottom of the oven B and are held in position by means of the latches H, the parts now assuming the position seen in Fig. 1, and the electricity, being conducted through the medium of a switch or similar device into the wires J, and thence through the heating-blocks, as has been explained, will, after completing the circuit through the heating devices, be conducted therefrom by the wire or conductor K, as has already been described. The broiler proper, 0, being rotatably mounted on the shaft D can be turned from time to time to the desired extent in unison with said shaft, so that the richjuices, &c., contained in the meats or viands, which are usually lost, can always be retained there in, since the broiler can be set so that either surface of the meat as desired may be at top or bottom or the meat can be caused to assume an upright position, if desired.

The operation of the heating devices seen in Figs. 6, 7, S, and 9 is substantially identical and it is thought will be apparent from the foregoing description without further explanation.

The operation of the oven seen in Fig. 10 has already been described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
