Application October 23, 1936, Serial No. 107,141

10 Claims.

As the title indicates, the device of thisl invention relates .to broilers, particular reference being had to the type of ,broiler used in hotels -and restaurants, for the purpose of brqilinlg 5 meats, etc. However, in addition to serving as broiler for meats, etc., it includes features that, insofar as I am aware, have never been used heretofore, i. e., the device serves also as a hotplate for the purpose of preparing the so-calledV l short-order, also for the baking of pastries.

It has been a common experience heretofore, in broiling meats, that the operator of the broiler was very apt to either over d'o the meat or to broil it too'rare,` either condition being unsatisi factory to the epicure of well prepared foods.

It is therefore a prime object of the present invention to provide a broiler wherein the subject l matter may be brought within variable degrees of heat, to the end that the heat of the 20 broiler may be more eiilciently applied than heretofore.

A further object provide a broiler that is simple in design, does not require expert attendance, and which pro- 25 duces superior results. l

A further object of the invention consists in the novel anduseful provision, formation, construction, association, and relative arrangement of parts, member and features, all as shown in certain embodiments in the accompanying drawings, generally described, and more particularly pointed out in the claims. i

In the drawings of which there are four sheets:

Figure 1 is a front elevation of the device of this invention.

Figure 2I is a plan view of the same.

Figure 3 is a side `elevation showing operating mechanism of the broiler. f

Figure 4 is a side elevation taken on line 4 4, Fig. 1.

Figure 5 is a sectional elevation taken on line 5 5, Figure 6.

Figure 6 is a front elevation, partially in secof the present inventioni is to.l

ing a at top surface I2, and sides I4 and I6, .the Whole of which may rest upon legs or feet I8, or it may rest upon a suitable frame (not shown) without being provided with the legs I3.

The interior of the broiler III is provided with a suitable leverage, whereby a grill plate 20 upon which meat, etc., to be broiled, may beadjustably positioned with respect to'a series of burners 22.

The plate 20 may also be withdrawn from the body of the broiler, for the purpose of placement or removal of meats, etc., and as'shown in Figure 1 a drop-plate 24 to which the'grill plate 20 is secured, provides not only an exterior finish to complete the frontal appearance of the device when in normal closed position, butI it also provides a means to with-draw the whole of the grill plate and the plates entrained supporting mechanism, and at the same time affords means tov manually vary the elevational position of the grill plate 2U, all of which will be hereinafter more distinctly pointed out.

A scoring or pattern device 26 is adjustably positioned with respect to the grill plate 20, and is operable through a leverage system which is formed as follows.

'I'he scoring device 26. comprises a frame having longitudinal and transversely extending members 29 and ,10 which form a pattern, and are integrally joined to the frame 30. The frame is pro,- vided with lugs 32, which extend through arcuately formed slots 3| in the side walls I4 and I6, when the scoring frame is in operative position. The lugs 32 are pivotally supported upon a rockarm 34, which is oscillatable upon a boss 35 pro- `iecting from the sides I4 and I6. The rock-army 34 is provided with an. arcuately shapeddependent linger 36, the end of which is bifurcated for a purpose to be hereinafter set forth.

A link 31 connects the rock-arm 34 with a lever 38 which is substantially L shaped and which is secured upon a longitudinally extending square shaft 4Il,`suitably journalled in the sidewalls I4 and I6. The opposite end of the shaft 40 is fitted with a second lever 38a, The leg 38' of lever 3B is pivotally connected to a manually operated lever 42 having a handle 43, and which is provided with serrations or teeth 44 adapted to engage and interlock upon the lower lip of a slot 45 formed in the marginal front plate 46.

Springs 38h, have one end attached to the rockarm 34, while the opposite ends thereof are attached to levers 33 38a, are adapted to counter-balance the dead-weight of the scoring frame 26'. y

o? purpose aforestated.

The finger 36 which is formed. as a part of rock-arm 34, is adapted to support a counterbalance and to forcibly lift the same. The balance 46 is pivoted upon a boss 4l and is provided with a weight 48, which is of slightly less weight than a swingable window 50 which is secured to the balance arm 46 by any suitable securing means 52. The balance arm 46 is provided with a bend 53, so that the arm, which is pivoted upon the exterior of the walls |4 and I6, may extend through an arcuate slot 54, and bc attached to the window 50 at a point interior of the body loa.

A manifold 55, shaped as an inverted "U, is adapted to supply fuel to each of a series oi burners 22. Valves 56 are adapted to regulate the fuel supply. Superposed upon and resting as a hood over the burners 22, I provide refrac tory blocks 51, for the well known purpose of improving combustion of the fuel, as well as tending to regulate and make the dissipation of heat more even. As a further means of heat regulation to avoid spot temperatures in the grill plate I2, I place a sheet top surfaces of the refractory blocks 51.

The manifold 55 is provided with fuel from a A chamber 60 which is built in the frame of the boiler, and it is upon the top surface of the longitudinally extending chamber 60, that I mount a pair of bearings 6| and 6|a, while upon a second frame member 62, I place a second pair of corresponding bearings 63 and 63a. These bearings are adapted to receive xed rods 64 for the purpose of slidably supporting mechanism 66 which in turn supports the grill plate 20 in adjustable relation to the burners 22 and which -alsopermits the grill plate to be moved to a point exterior of the broiler. The bearings Gla and 63a are formed with an open side, as shown in Figures 6 and 7 to permit lateral expansion due to heat.

As shown in Figures 5, 6 and 7, the mechanism 66 comprises a pair of sleeves 68. which are integral, and are made rigid by means of a web 69, while rearwardlyof the sleeves, I form vertically extending brackets 10, having bearings 1| to journal pintals 12, upon which is pivotally supported a frame 14, having arms 16.

The free ends of the arms 16 are pivotally secured to the rigid legs 18, which in turn arc secured to the grill plate 20 by means of screws 80.

Counter-balances 10a are adapted to offset the weight of the assembled mechanism 66, and is formed of a tubular member 10b which is fitted over pintal 12 and rests between brackets 10. The member '10b is provided with rearwardly extending `tongues 1lb upon whichV weights 1|c are slidably mounted to effect graduated and accurate balance, while a dc` pendent member |Id. formed integrally with the member 1lb, is.adapted to bear against the frame 14 to lift upwardly thereagainst for the- A brace 82 is pivotaily secured t`o the lower end of the legs 18 and to the brackets 10 by means of pivots 84, and acts as an equalizer to keep the grill plate 20 in relatively level posi-A tion when the plate isdrawn forwardly as shown in Figure 5, however during the. broiling period the grill plate 20 is tipped rearwardly so that grease and fat may drain by gravity therefrom. This tilting motion is obtained by reason of the fact that the spaces between pintal l2 and pivot 56 of noncombustible material, such as asbestos` over the 84, and between pivots 18a and 18bare of different magnitude, thereby causing leg 16 to be swung forwardly when the grill plate 20 is elevated to broiling position.

The legs 16 are formed with a web 86, which on its inner face is provided with a boss 68 to which a pawl is pivotally supported, the free end of the pawl being adapted to engage one of a series of teeth formed inthe web 69.

A push rod 84, adapted to be finger pressed, is journalled at its one end in handle 96, which is secured to the front drop plate 24, while the other end of the rod rests in an aperture 08- formed in web 86, and is adapted to press against the pawl 30 to lift it from engagement with the teeth 92, when it is desired to raise or lower the mechanism 66, as shown in Figures 5, 7, and 8. The pawl functions to support the plate 20 in any one of' various elevated positions, and in so doing carries all of the unbalanced weight of the plate 20 and its associated train.

In order to heat the grill plate 20. for any purpose, burners |00, which are movable with the plate 20, are mounted upon bosses |02 formed as a part of the plate, and are sup,

plied with fuel from a manifold |04, `which is connected by means of a pipe |06 and flexible tube |08, with a valve I|0 in connection with the chamber 60.

In order to bring the scoring device 26 into effective operation it is necessary that the device i 26, conform with the position of the grill 20 regardless of whether it is tilted or in horizontal position, and to enable the device to be tilted, the levers 38 and 36a are provided with a slot 38 which is adapted to receive a pin 31' secured to the lower end of the links 31, thus permitting the frame and the link to assume any tilted position within reasonable limits, so that the framemay rest flat upon meats being broiled upon the grill 20.

To place the device of this invention in operation, it is only necessary to open valves 56 and to light the burners 22. After the broiler has come up to a sufficient heat, the grill plate 2,0 is manually pulledoutwardiy by means of handle 86 on drop plate 24. The articles to be broiled are then placed upon the plate 20, which is the forced inwardly by sliding the Whole of the leverage mechanism 66 inwardly over rods 64.

The intensity of the heat applied to the article broiling may be varied, not only by means of the amount of fuel applied. but also by proximity of the article to the heat of the burners. And this is accomplished by lifting up upon the handle 96 and simultaneously pressing upon the finger rest ||2 on push rod 94, to cause pawl 90 to be disengaged from teeth 92, and then lowering the whole of the adjustable mechanism 66, if the heat is too intense. If it is desired to more quickly broil the meat, it is only necessary to lift upwardly upon the handle 36 thereby causing the pawl A90 to follow and to move outwardly to la new position, which is then fixed by reason of the engagement of the pawl 90 with anew one of the teeth 62.

For the purpose of effect or appearance, it may be desirable to mark the steak being broiled. and to eifect such searing marks, it is only necessary to lift handle 43 and to pull it outwardly. thereby lowering the scoring or marking device or frame 26. until it rests upon the steak, upon which the pattern of the frame is then seared.

The handle 43 and its associated parts should be operated for the purpose of' lifting the swing- 7 able window and the scoring device 2B prior to removal of any object being broiled. During the broiling operation the condition of the subject matter may be observed through the windows H6 which are preferably made of Pyrex glass or its equivalent.

In order to combine more general utility in the device of this invention, as previously mentioned, I have provided a grill plate I2 upon which the so-called short-order may be prepared.

The plate l2 is hinged at |2a to the body |00. of the broiler, to provide ready access to the interior thereof for the purpose of inspection, cleaning or repair.

A groove H8 is adapted'to catch. grease, which drains through stub drain pipe H8a from which it enters detachable drain pipe |20. The pipe |20 being detachable for the purpose of removing hardened grease or fat derived from cooking operations upon the grill I2.
