Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed January 6, 1908. Serial No. 409,416.

To all whom it may concern:

Be it known that I, GEORGE GIOVANNA, a citizen of the United States, residing in the city of New York, borough of Manhattan, county and State of New 1 ork, have invented a certain new and useful Apparatus for Broiling Meats and the Like, of which the followin is a specification.

This lnvention is an a paratus designed for domestic purposes, suo as for broiling or roasting meats, poultry, or the like, before an open hearth or grate.

The apparatus is especially useful in restaurants, cafs and other public eating places where it is desirable at times to displa to the view of the patrons the operation of roiling or cooking meats; but some of the parts of the invention are useful in an apparatus to be installed in the kitchen, or'other place, which ordinarily is not accessible to the ublic.

. My apparatus makes provision or broiling a number of pieces of meat at a single operation, each iece being carried by a rotating s it, and all the spits being driven, prefera l from a single source of power. A pecuharityof the invention is that any one of the spits can be disconnected from the driving mechanism, and removed from the apparatus, while the other spits remain in operation, whereby the spit so removed may be sup lied with the material to be broiled or the roiled material removed from said spit.

The invention contemplates, also, a novel construction of the fireplace which accommodates the grate or hearth and one or more warming ovens. I

In the accompanyin drawings, I have illustrated one practica embodiment of the invention, but the construction shown therein is-to be understood as illustrative, only, 2nd not as defining the limits of the inven- Figure 1 is a front elevation of an apparatus for broiling meats embodying this invention. Fig. 2 1s a horizontal section on the line 2-2 of Fig. 1. Fig. 3 is a vertical cross section on the line 3-3 of Fig. 1. Fig. 4 is an elevation looking at that side of the apparatus which is provided with means for operating the rotary spits. Figs. 5 and 6 are enlarged detail views, partly in section, of parts entering into the construction of the apparatus.

' In the embodiment of the invention shown by the accompanying drawin s, the apparatus is provided with a frame, K, of composite construction. This frame comprises suitable upright members, a, a, a and horizontal members, a said vertical and horizontal members producing a skeletonized structure which is fi led in with suitable tiling, a. The

tiling may consist of blocks or slabs com osed of refractory material, and in some instances it is preferred to use glazed tiling which form an open fireplace and one or more inclosed ovens.

As shown in the-drawin s, the frame, A, is constructed to produce a replace, B, having a forwardly extending hearth, b, a central oven, 0, one or more side ovens, l), D, and an overhanging hood, E. If desired, however, one or both of the side ovens may be omitted, so that the apparatus may have only a central oven, and, furthermore, the hood, E, may be dispensed with, but these details may be modified as desired by the skilled constructor.

From the upper part of the fireplace, B, leads a stack or uptake, 1). With this fireplace communicates the chamber of the overanging hood, E, whereby the draft through the fireplace will carry the smoke, fumes and odors from the broiling meat into the stack or uptake. The frame work is provided in rear of the oven, C, with a descending flue, c, which communicates with the ash pit, 0. Over this flue, c, is arranged a grate, F, which is fitted removably in the fireplace, B, in the rear of the hearth, b. The grate, F, is held in place by suitable means, but as shown in Fig. 3, I employ a pivoted dog, f, adapted to enga e with a toe plate, f. The dog is shown as eing ivoted to the grate, F, and the toe piece is xed to the hearth, b, whereby the dog when engaged with the toe piece operates to force the rate against the back wall of the frame work.

The ovens, D, D, are arran ed at the respective sides of the frame wor or on opposlte sides of the fireplace B, whereby said ovens are adapted to be heated from the grate in said fireplace. Said ovens are provided with appropriate doors, (1, and in Fig. 2, the door of the oven, D, is at the back of the structure, while the door of the other oven, D, is at the frontof said structure, but its arrangement is optional and may be modified as desired. The oven, C, is below the hearth, b, and extends in front of the grate, F. Said middle oven is provided with a swinging door, 6, adapted to drop downwardly in front of the ash pit, c, and this door has a sliding catch,

- adapted to be engaged with a keeper, e the latter being fixed on the frame work.

The hot embers and ashes from the ate accumulate in'the ash pit, c and the H ue, 0, so that the oven,-C, will be heated from the waste fuel. a I My apparatus employs a plurality of rotat ing spits,'G, which are in front of the grate,

F, said, spits being rotated simultaneously from a common driving mechanism, whereby the material on the spits is exposed to the heat of the grate. Any desired number of spits -1nay beemployed, and they may be arranged in any desired order with relation to the grate, but as shown in the drawings, I employ four of the spits extending horizontally across the fireplace, said spits being mounted in substantially the same vertical plane and in front of the grate. Each s it is shown as consisting of a spindle, g, an a rod, 9. The spindle is considerably longer than the .rod, and it is pointed at one end. The rod, "g,is pointed at one end and'provided at its other end with an arm, gZ-terminating in a collar, 9 the latter being clamped on the spindle, 9, whereby the rod is disposed parallel to the spindle. The free pointed end of the rod is supported by a clamp, 71., which is fitted on the spindle so as to be set at any desired point along its length by a binding screw, h. The clamp extends outwardly from the spindle, and it engages with the rod, g, whereby thearm, g and the clamp, h,/SllPPOI't the rod parallel to the spindle and in fixed relation thereto.

The spits are mounted in/bars, H, I, J, so

that they are adapted forrotation on their axes, and an important feature of the invention'consists in a construction of the bars 'fitted the clamping screws or bolts, '8

which permits the spits to be removed individually and without disturbing the remainin spits of the series.

he bar, J, is fastened to the frame work in a vertical position and at one side of the fireplace, B. Said bar, J, is provided with suitbar; I, is thus fastened adjustably -to the bar is fp each 0 which opens through the front edge frame at one side of the fireplace, and said rovided with a plurality of slots, 1',

of the bar, substantially as shown in Fig. 5.

The bar, H, is arranged on one side of the frame, A, substantially as shown in Fig. 1,

said bar, H, being parallel to the bars, I, J.

The bar, H, is constructed similarly to the bar, I, and is fastened adjustably to the i frame, A. Furthermore, the bar, H, is provided with the slots, k, which open through one edge of the bar, and these slots, is, are in alinement horizontally with the slots, 7', of the bar, I. It will be 'seen'that the spindles, g, of the spits, G, may have their pointed ends inserted into the openings of the bar, J, and said s indles are adapted to be slipped throug 1 the alined slots, j, k, of the bars, H, I, whereby the spindles of the spits are adaptedto be inserted or withdrawn easily and quickly.

For the purpose of retaining the spits in the bars, it is preferred to employ suitable catches, K, see Fi 6'. Said catches are associated individua ly with-the s its, and each catch is pivoted as at k to the ar, H. The catch is shoulderedto engage with the spindle of the spit, and said catch is adapted to drop by gravity across the slot, Zr, in the bar, whereby the spindle, g, is prevented from lifting accidentally out of its bearings in, the sup orting bars.

. e spindles, g, of the rotary spits are provided with sprocket gears, Z, which are adapted for engagement with an endless chain. This chain is confined in cooperativerelation to the gears, Z, by a guide bar or guard L, the'latter being shown in Fig. 4 as supported in a fixed osition at one side of the chain, the sproc et wheels Z engaging with the chain on its opposite side. The chain is supported and operated by suitable sprocket wheels, m, m, each carried by a suitable shaft, m The shaft of the lower sprocket, m, is mounted in adjustable bearings, 71., provided on one side of the frame, as shown 111 Fig. 4. The shaft of the upper sprocket, m, is. provided with a suitable driving member, such as a pulley,'0, but this driving member may be operated by any suitable means, such as an electric motor.

By reference to Fig. 4, it will be seen that the driving chain travels in a vertical path, and that the gears, Z, of the series of spits engage with one lead of said driving chain. The driving chain is back or just in the rear of the vertical series of sprocketgears, and a each sprocket gear can be Withdrawn from engagement with said driving chain without interfering with either of the gears on the other spits. From this construction, it will be seen that any one spit of the series can be dismounted from the frame, and its gear, Z, disconnected from the driving chain without interfering with the operation of the remaining spits of the-series, whereby any one or more spits can be dismountedforthe purpose of placing meat thereon, or for removing broiled meat therefrom, while, at the same time, the remaining spits may be continued in operation.

The operation is as follows: A fire is built in the grate, F, any. suitable fuel being used 130 driving member shown in Fig. 4 as a sprocket in the coarse for the purpose. The heat of the fire is communicated to the side ovens, D, D, and the ashes drop through the flue, 0, into the ash pit, c, for the purpose-of heating the middle oven, 0. The spits, or any one or more of them, are dismounted from the sup orting bars, and the material to be broiled paled on said spit. To accomplish this, the clamp, h, is removed from the spindle and the rod, the pointed ends of said spindle and rod are thrust into or through the material,

and the clamp is replaced for the purpose of supporting the free end of the rod. In replacing each spit the pointed end of the s indle is thrust into an o ening of the 'bar, the s indle is then passed through the slots liars, H, I, the sprocket wheel is engaged with thedriving chain and the latch, K, is dropped into engagement with the s indle and across the slot in .the bar, H. he spit is thus mounted in the frame to be held by the catch against displacement, and said spit is rotated by the ear, I, which is driven from the chain, L. A l the spits are rotated from-a single chain, and said spits are in close proximity to the bed of incandescent fuel contained in the grate, F. The meat impaled on each spit is resented on all of its sides to the heat of the re, thus insuring the uniform and thorough cooking of the substances, while the smoke and odor arisin from the meat is collected by the hood an directed into the stack or uptake. When the meat on any one s it is cooked, the spit is readily dismounte from the frame, the clamp is withdrawn from the spindle and the rod, and the meat then removed from the spit.

My apparatus is simple in construction,

efficient in operation and economical to manufacture. The supporting frame covered by the tiling presents a neat ap earance so that the apparatus ma be use for display purposes. None of t e parts are likely to be worn when in use except the fireplace, which is directly exposed to the heat, and

- the apparatus is durable in service.

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

1. In an a paratus of the class described, a pluralit o spits, a driving element common to al of said spits and cod erating directly therewith for rotatin t e same simultaneously, and means w ereby a spit may be disconnected from the driving means an removed from theapparatus while re taining the other spit or spits in operative re lation to said driving means.

2. In an apparatus of the class described, a plurality of spits, and an endless driving member common to all of said s its and cooperating directly therewith, eac spit being is im-' driving member whi member 006 erating wit removable from cooperative relation to said e the other spits remain in operative engagement therewith.

3. In an apparatus of the class described, a supporting frame, an endless driving member, and a urality of spits mounted removably in said frame, each s it having a driven driving member and adapte to be disconnected at will therefrom, said endless driving member being common to all of the spits and cooperating directlywith the driven members thereof.

4.. In an apparatus of the class described, a supporting frame, an endless driving chain, a plurality of spits each having a sprocket wheel engaging with said chain, and a fixed uide member in cooperative relation to that ead of the endless chain with which the sprocket wheels are engaged, whereby the c ain is precluded from disengagement from said s rocket wheels.

5. 11 an ap aratus of the classdescribed, a sup ortin rame comprising bars, certain of said barsIiaving slots which open through the edges thereof, a plurality of s its supported in said bars and removab e bodiy therefrom through the slots therein, means for retaining the spits in the slotted bars, and an endless driving member cooperating with each of said s its, whereby each s it may be dismounted rom the frame while t e other spits remain in cooperative relation to said driving member.
