t'lih'e present invention is directed to a simple,

practical, novel grill structure, for cooking provide a very practical, useful and economical structure for cooking wieners or frankfurters, turning them continuously during cooking over a bed; of coals or other heat source. beneath, and to provide simple and effective means for continuously turning said wieners or frankfurters about. their lengths located horizontally over the coals or other equivalent source of heat, which driving connection is instantly interrupted by moving. the mounting means upon which the articles cooked are swung to a horizontal position for removal and replacement by others, the swinging of the mounting means back to operative position auto matically connecting a driving motor with therotating holding means which carries the. articles which are to be cooked.

An understanding of the invention may be had from the following description, taken in connection with the accompanying drawings, in which: Fig; 1 is an elevation of the grill structure of. my invention,

Fig. 2 is a transverse vertical section therethrough,

Fig. 3 is a fragmentary longitudinal vertical.

section,

. Fig. 4 is a, fragmentary plan view and horizontal section atone end of the machine, and

Fig. 5 is an enlarged horizontal section through thefrankfurter or Wiener holding blade showing.

called its front edge, is bent upwardly at right. angles to provide a front 2. Vertical ends 3, also of sheet metal, extend above the upper edge of the front 2. The body structure thus described;

is supported above the floor at its corners by legs 4. The back is open, except for a horizontal crossbar 5 of channel form whichextends be tween the ends 3 substantially midway between their upper and lower edges. I

A relatively heavy wire screen 6, connected at its lower edge with the front 2, extends upwardly above the ends 3 and is then turned to the rear tomake a horizontal top section! as shown.

A receptacle 8 vfor retaining ashes is placed above the bottom I. A basket' 9, having, vertical sides and ends and a horizontal bottom I0, is 10-- solai s. (01. ire-421,)

cated' above the ash receptacle 8. Over the bottom II] a lining llof fire resistant material is placed, above which charcoal [2 which may be" burned is carried. Said bottom liner II and the" bottom [0 of the basket have vertical openings in conjunction with each other for supplying air to the burning fuel. The basket is suspended by vertical fiat bar l3, connected one at each end and extending upwardly at the inner side of each end 3 of the body structure, each of the bars [3 having a number of vertical spaced openings lA, through se-- lected ones'of which pins 15 may. be passed, the pins being carried by the ends 3 of the body. In.

vthis manner the basket may be adjusted verti cally to different positions to bring the heat. from the burning fuel closer to or farther away frozn;

the 'food articles which are being cooked. The

draft of air through the openings in the bottom lfl'and liner II is controlled by a horizontal draft plate It, located underneath the bottom Ill and slidably held at its ends by angle bars I? secured to the basket. Said draft plate. l6 has openings which in one position of the plate (Fig. 2) aline with the openings through the bottom it of the.-

' form, is hingedly connected at its lower edge to the bar 5.. It. may be swung downwardly to ahorizontal position (Fig. 2') and supported by chains, as at Hi. It may be turned to a vertical position, shown in dashed lines in Fig. 2, and" releasably latched therein by latching rods 20,;

best shownin Fig. 1, which at their outer end portions pass through openings in the ends 3 of the body structure, and at their inner ends are.

pivotally connected to a rocker bar 2!, which'is manually rocked by a handle 22 to withdraw the latchingrods when the plate [3 is to be turnedfrom vertical to horizontal position, and to pro-4.

ject the rods when the plate It has been turned back to upper position. I a

back plate it within which a number of spaced sprockets 24 are located and rotatably mounted, operatively connected with which is an endless, chain 25 which, when driven, rotates-all of,the-.

sprockets continuously. The bar '23. atpne endentends beyondthe adjacentv end .-3 of the bowl- Fig. 2, there is a disconnection of the clutch members 28 and 29.

Each of the sprockets is mounted upon a stud shaft 3, which at one end is mounted in the bar 23 and passes through a second bar 3| parallelv thereto and against the plate 18, and through said plate, as in Fig. 5. At the projecting end of each stud shaft 39, a holder for a Wiener or frankfurter is detachably connected. The holder consists of a pointed elongated blade or spit 32, which is secured to the closed end of a sleeve 33 provided with a bayonet slot (Fig. 2) for connecting with a pin extending outwardly from its associated shaft 30.

The Wiener or frankfurter food article is impaled upon the blade or spit 32 when the back plate I8 has been turned to horizontal position, as shown in Fig. 2. When all, or as many as wanted of the blades or spits 32 have been supplied, the back plate 18 is turned to andsecured, in vertical position. The motor 26 is operated and there is a continuous rotation, at a desired low speed, of the wieners or frankfurters over the bed of coals at l2. Preferably burning charcoal is used as a source of fuel, but of course any other available equivalent heat source ,may be used. In the structure shown, the burning of the fuel may be increased or dim nished by regulating the draft plate l6, and the bed of burning charcoal may be moved toward or away from the longitudinally turning food articles above. When the wieners or frankfurters have been sufiiciently cooked the back plate I8 is turned to the horizontal position, as in Fig. 2, and they may be removed and replaced by others. The detachable connection of the sleeve socket 33 to a stud shaft 30 is so that the spits may be removed for cleaning.

The grill structure in use may be located back of a window so that passers-by may readily see the operations performed, look'ng through the screen 6. convenient place to put buns to be warmed while the wieners or frankfurters are being cooked. An attractive showing is provided.

The structure described is very practical, useful, readily and easily operated, and has proven exceptionally satisfactory in use.

The invention is defined in the appended claims, and is to be considered'comprehensve of all forms of structure coming within their scope.
