This invention relates to cooking appliances and refers particularly to a portable home barbecuing device which may be employed for barbecuing, broiling or toasting meats or other articles of food.

One of the objects of this invention is to provide a home barbecuing device of the character described which is suiciently small and light as to permit its being readily portable but which is so designed as to cook or barbecue food by a concentration of heat from a heating element upon any desired cooking area, with the result that the cooking is accomplished at a more rapid rate than is possible to obtain with conventional barbecuing devices, the rapidity of the cooking rate leaving the food relatively moist as compared with that cooked on previous barbecuing devices.

Another object of this invention is to provide a device of the character described wherein the heat source is in the form of a hood-like reflector having a heating unit disposed therein, and which is hingedly mounted to swing up from its operative position to provide unrestricted access to the food being cooked.

Another object of this invention is to provide a device of the character described wherein the heating element is mounted within a hood-like reflector having a substantially parabolic cross section, and in which the heat source comprises an elongated heating element located in the horizontal plane extending through the focal point of the cross sectional area, whereby the heat from said source is in effect focused by the reflector to concentrate the heat in an area of limited dimensions.

Another object is to provide a device of the character set forth in the preceding paragraph wherein the heating element may be moved vertically Within the reflector to change the area upon which the reflected heat is concentrated.

It is also an object of this invention to provide a device of the character described which, while designed primarily for roasting or barbecuing meat, can be employed for broiling, toasting and other similar forms of cooking.

Another object of this invention is to provide a device of the character described which is neat in appearance and which can be readily kept clean.

Another object of this invention resides in the provision of a device of the character described so designated that the operating mechanism thereof is encased and concealed from View to thereby insure a neat external appearance and also protect the mechanism.

With the above and other objects in view which will appear as the description proceeds, this invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described, and more particularly defined in the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

The accompanying drawings illustrate one complete example of the physical embodiment of the invention constructed in accordance with the best modes so far devised for the practical application of the principles thereof, and in which:

Fig. 2 is an end view of the barbecue device shown in Fig. l, a portion of the end of the reflector hood being broken away to show the mounting of the heating element therein;

Fig. 13 is a vertical sectional view taken through the line III-III of Fig. 1;

Fig. 4 is a top plan view of the device with a portion thereof broken away;

Fig. 5 is a fragmentary detail View illustrating the manner in which the rotatable food supporting spit is removaly Aheldl in position.

Fig. 6 is a detail sectional view taken through Fig. 5 on the plane of the line VI-VI;

Fig. 7 is a perspective view of the inner end portion ofthe rotatable spit; and

Fig. 8 is a detail sectional view taken through Fig. 2 on the plane of the line VIII-VIII.

Referring now particularly to the accompanying drawings in which like numerals indicate like parts, the numeral 5 designates the base of the entire structure. The base is rectangular in shape and is designed to be set directly upon a table or other supporting surface. If desired, legs 6 may be provided for the base.

One end of the base has an upright hollow standard Vor pedestal 1 secured thereto as by screws 8. While it is preferable from manufacturing considerations to fabricate the pedestal and base as separate units and then assemble them, it is, of course, apparent that these parts could be made as one integral unit, for in effect the pedestal constitutes merely a continuation or extension of the base.

' Supported on the top of the pedestal 1 is a heat source generally indicated by the numeral 9, the heat source comprising an elongated hood-like support I2 preferably formed 'of insulating maif terial such as a ceramic insulating support having at one of its ends a vertically extending wall i3 of substantially triangular shape, the end wall I3 having a flange I4 through which extends a supporting screw I5 by which "one end `of the support I2 may be suspended in the hood. The opposite end Wall I6 of the support 'is siinilarly constructed and is secured in the hood I by means of a screw Iv'l. As will be understood by those skilled in thisart, the screws I and I'I may be threaded directly into the ceramic material or to metal inserts I8 embedded within the flanges of fthe 'end walls.

The end walls i3 and I5 of the supportare connected together by afpair of bars I9 and 20 formed f with the end wall structures, a plurality of verticallyjextendi'ng brackets 2| being formed at regular intervalsalong the 4lengths of the bars I9 and `2i), each of the brackets 2| being of substantially triangular cross section but having a depression 22 in theapex thereof in which may be Aseated the coil II. Thus the support I2 provides a plurality of's'upportin'g'points spaced'along the length of the coil II to Ihold this coil in substantially va straight yline position, and as will be observed from an inspection kof (Fig. 2, disposes the longitudinal axis ofthe coil II substantially at the focal point of Atl'ieparabolic cross section of the hood I.

The screws I5 and ,'I'I are .preferably provided with knurled yheads 23 by which they may be readily turned tofrstjinitially adjust the axis of the coil IIVat vthe ffocal point` of the reflector throughout the length `of the coil, and-thereafter may beturned to raiseo'r lower the coilrelative to this focal point Yfor the purpose `of changing the areagof the base 5 lupon which the reflected heatv of ythe heating coil may be concentrated, the purpose oi which will be more fully described hereinafter. A,

For barbecuing, Aa vre'tatable spit 36 is provided to support meatancl other food inthe space under the heat source. This spit 4is rotatably mounted and deriven by means -to behereinafter described, located within thefhollow pedestal V'I.

:The reiiectorA I5 is hingedly attached to the pedestal-asjat 215 so as toenable the same to be swung upwardly from its horizontal operative position to a raised position (indicated in dotted lines in Fig, l) affording unrestricted access to the food being 'barbecued -or broiled.

The base 5 comprises essentially a stamped and formed `instal frame Vopen at its top Yto removably receive a drip -pan 25. The pan -`obviously functions to .catch grease and drippings L.from the meat supported lon the spit; and for broiling or toasting, .a removable wire rack 26 is supported across' the 4top of the pan..

i l The uprighthollow4 standard or pedestal I consistsof an outer housing'or shell 21 stamped and formed from sheetnietal and l'an'innerframe 28 formed of heavier metal. Thisinnerframehas arear upright portion tb'verlying the inner surfac'eerjthe're'ar wan "su f the 'housing or shell, and ain'l'fpriglft Inrrber h3! "adjacent Al'Olnlli 4 spaced from the front wall 32 of the housing or shell.

Bearings 33 and 34 carried respectively by the upright members 29 and 3| of the inner frame rotatably mount a tubular drive shaft 35. One end of this drive shaft extends through a hole in the rear wall of the housing or shell to be accessible from the space between the base and the heat source to permit insertion of the inner @nu fof a spit *as 'into the tubular fdrive shaft.

As best shown in Fig. '7, the inner end of the Aspit is bifurcated as at 37 to embrace a cross pin 38 extending through the tubular drive shaft and thereby drivingly connect the spit to the drive shaft.

A spring detent 39 confined within a cover plate@ 'on therea'r wall 30 of the housing or shell engages -in an annular groove 4I in the spit to readily detachably hold the spit assembled With its drive shaft. The spring detent 39 may take any suitable form and in the present instance is illustrated as a hairpin-'shaped wire 'spring member yheld in place Iby screws or other fastenings engaged in the rear upright 29.

The cover plate 40 conceals the detent and proV- Vides a neat external appearance. This cover plate is `preferably lheld 4inplace 'by Ltangs 42 which pass through the walls 29 land 30 to be struck over as shown in Fligjd I l Between its bearings "33 and 34, the tubular drive sha-ft mounts a gear or worm wheel"43 which is preferably iiXed to the shaft bythe same cross pin 33 used to provide a drive connection'to the spit.

lVIeshing with the gear or Worm wheel 43 is a worm 44 which is driven by an electric motor 45 conveniently supported on part of the inner 'frame so Las to be completely encased Within the hollow pedestal or standard. Obviously the motor through the worm and worm wheel drives the spit to revolve'the same'and to thus continuously turn 'the food which may be impaled upon the spit.

To nx food upon thelspit -3'6 in such manner that'ro'tationof the spit 'Siil will /insurerotaton of the food, Ipr'efer -to .provide additional prongs upon which the'food may also be impaled,'one of such sets of .prongs vbeing illustrated at 46 as comprising abar 47 secured as indicated at 48 to the shaft of the spit 36, ythe bar-extending on opposite sidesof rthe shaft'to mount a pair of pins 49 lextending longitudinally of the spit v36, the connection `'46 lbeing'formed in any suitable manner so as to rigidly secure the bar and the prongsfor rotation with the shaft of the spi-t3B. Also, if desired, an additional set of `prongs 50 may be mounted upon the Aopposite. end of the spit 36 adjacent the sharpened end 5I,`the. prongs being supported on opposite sides ofthe shaft of the spit 36 by means of a bar 52 through which the sharpenedend 5I of the spit may pass, the bar 52 being preferably fitted witha collar -53 frictionallyengaging the spit 36 but-permitting its ready removal whenever a ypiece of food is to be impaled upon the spit y3G. l

Thefheating element and its `reiiector maybe swung on its hinge 2'4 whenever access is desired to the spit 36 and food which may be impaled thereon by anysuitable means, one form of mechanism Vfor swinging the 4-heatsource 9 from its normal horizontal position as shown in full lines in Figfl to its elevatedposition as shown in broken lines in Fig. 1 comprising a knob 54 on the front wall 32 ofthe pedestal, 'the knob being secured to a stub shaft 55 mountedin a suitable bearing 56 secured to the front wall 3| of the inner frame 28. The inner end of the stub shaft 55 may be additionally suportcd by a bracket-51 indicated as of generally Z-shaped construction, one arm of the Z being rigidly secured to the wall 3|'of the inner frame 28, while the other arm of the Z is disposed at some considerable distance from the wall 3| and is provided with a bearing member 58.

Secured to the inner end of the stub shaft 55 is a crank arm 59, to the outer end of which is pivotally secured a link 60 which extends upwardly adjacent the rear wall of the pedestal, the link having its upper end bent over in the form of a. clevis 6| to engage a pin 62 which may be secured to the hood I0 by striking up from an inturned end 63 of the end wall of the hood a pair of ears 64 and B5 spaced forwardly of the pivot or hinge 24 which interconnects the hood I0 with the pedestal 24. As viewed in Fig. 3, it will be observed that the link 68 has its central portion cut out as indicated at 66 so as to straddle or freely pass the spit shaft and its bearing 33 without interference therewith.

The weight of the hood I 0 and the heating element structure associated therewith will ordinarily be such as to normally urge the hood into its horizontal position, and to aid in holding the hood in its elevated position against the effect of gravity, I prefer to employ a tension spring 61, one end of which is secured to the link 6|! while the other end is secured to the top plate of the frame 28, the force of the spring 61 tending to balance the weight of the hood I0 and thus permitting ease of elevation thereof upon rotation of the knob 54.

The throw of the crank arm 59 is approximately 180 so that 180 of rotation of the knob 54 from its normal position as shown in Figs. 1 and 2 to the position it will assume when the hood is elevated is required, and the hood may be maintained in either its horizontal position or its elevated position by the provision of a spring 68 (see Fig. 8) secured upon the inner face of the wall 32 of the outer housing of the pedestal having a hemispherical detent 69 securedv thereto to project through an opening in the wall 32 and into either of two depressions 10 and 1| formed on the inner surface of the knob 54 (see Fig. 8) and disposed on diametrically opposite sides of the stub shaft 55. Thus, when the knob is in its normal position as shown in Figs. 1 and 2, the detent 69 will engage the depression 1| and restrain any effect of the tension spring 61 to inadvertently elevate the hood I8 from its horizontal position, while when the knob has been rotated through 180 the detent 69 will engage in the depression 10 and will hold the hood in its elevated position against any tendency of the weight of the hood III to move the hood from the elevated position.

By referring particularly to Figs. 2 and 4, it will be observed that on the rear wall of the pedestal 'I there are mounted two electrical switches 12 and 13, respectively, to which a suitable ilexible electric cable or cord (not shown) may be connected, the switch 12 being connected by suitable circuit connections to the heating element II while the switch 13 may be employed to control the operation of the motor by suitable electrical connections (not shown).

'I'he electrical connections to the heating element I1 preferably include a two wire conductor cable or cord 14, the conductors of which are connected, respectively, to terminals 15 and 16 mounted upon the end wall I3 of the heating element support II, the terminal 16 being also coupled to the end of the heating element II adjacent the wall I3. The terminal 15 has connected thereto a conductor 11 which extends through openings 18 in the brackets 2|, whereby the conductor 11 will be supported throughout the length of the heating element support I2, a suitable terminal 19 being mounted upon the end wall I6 to which the conductor 11 and the opposite end of the heating element I may be connected.

From the foregoing description, it will be apparent that I have provided a home barbecue device Which is completely self-contained and in which meat or other foods to be barbecued may be'readily supported upon the spit 36 to receive the most intense heat from the heating element I I by focusing the heating element relative to the hood I0 in such fashion as to cause reflection of and concentration of the heat over an area lying substantially at a longitudinal horizontal plane intersecting the axis of the spit 36. By employing this arrangement, a heating coil II of relatively small wattage may be effectively employed to produce intense heat on and in the foods impaled upon the spit 36.

It will also be noted that my barbecue device may be readily adapted to the broiling or toasting of other foods disposed directly upon the wire rack 26, in which event the spit 3.6 may be removed merely by pulling the spit 36 out of its tubular drive shaft 35 to provide space above the wire rack 26 into which foods placed thereon may extend. In the event of use of the barbecue device for such toasting or broiling of foods disposed on the rack 26, I prefer to change the position of the heating element II in the hood I8 to extend the area of focusing of the heat, as well as to change the region at which the most intense heat will be concentrated to a level below the spit 36, This change in the position of the heating element can be readily accomplished by turning the screws I5 and I1 an equal amount to raise the heating element I to a higher level in the hood I0.

By employing the parabolic-type of reflector and the elongated heating element associated therewith for disposition at the focus of the reflector, permits the concentration of a maximum amount of heat from a heating element of given size upon the foods to be cooked, thus permitting the cooking to be accomplished with a considerable saving in electric current costs. Also, by changing the position of the heating element relative to the focus of the reflector to concentrate the heat at different horizontal planes and over different sizes of horizontal areas, results in the acceleration of the rate of cooking, tests of the device showing not only great savings in time required for cooking a given mass of food, but also insuring the maximum conservation of the moisture within the food.

While I have shown and described the preferred embodiment of my invention', I do not desire to be limited to any of the details of construction shown or described herein, except as defined in the appended claims.

I claim:

l. In a food cooking device of the character described: a base; an upright hollow pedestal disposed at one end of said base and having spaced front and back walls; a hood-like reflector; means hingedly mounting the reflector on said hollow pedestal with the hinge axis of said connection near the front wall so that the top of the pedestal supports the reflector in a substantially horizontal 7 position extended out over the base; and means concealed Within the hollow pedestal and actu-- ated from the exterior thereof for swinging the reflector on its hinge connection.

2.
