Specification of Letters Patent.

' Patented Nov. 5, 1907 Application filed September 29.1906. Serial No. 336,764-

To all whom it may concern:

Be it known that I, GEORGE J MILLER,.8. citizen of the United States of America, residing at Kansas City, in the county of Jackson and State of Missouri,- have invented certain new and useful Improvements in Broiling Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others to make and use the same, reference being-had to the accompanying drawings, forming apart of this-specification.

. The object of the invention primarily is an apparatus for broiling meats, poultry, etc., in which the meats to be broiled may be turned quickly when exposed to the fire and the juices thereby preserved. SecondThe turning of-the broiler while being elevated in position above the heating grate. Third-To communicate a down draftto the smoke and vapor during theprocess of broiling. Fourth'-To enable the attachment of any draft apparatus for forced draft.

The invention consists in the novel construction and combination of parts such as will be first fully described and'then specifically pointed out in the claims.

In the drawingsFigure 1 is a view in perspective of the novel broiling apparatus, aportion .of the case or frame being-b oken away to show the support-for the inner ends of tne removable ventilating and heating grate. Fig. 2 is a plan view of the apparatus with the broiler removed, the heating grate being broken away to show the lower chamber and the aperture and cover in the bottom of the chamber. Fig. 3 isa transverse vertical sectional view of the apparatus as seen in Fig. 1. Fig. 4 is an end view ofthe upper portion of the frame showing the broiler supporting frame and the broiler rotating devices in an upwardly extended position. Fig. 5 is a detail side View enlarged of one of the outer jointed bars connected with the broilershowing the ratchet teeth in the jaw or yoke. Fig. 6 is a plan view of the jaw or yoke showing the-ratchet teeth. Fig. 7 is a detail side-view of the separable supporting plates for the trunnions of the broiler on the broiler supporting frame. Fig. 8 is atransverse' sectional view enlarged of the trunnion showing the ratchet teeth thereon. Fig. 9 is a detail view of the adjusting bolt and nut for the jointed arms. Fig. 10 and 10 are views of the outer jointed bar connected with the broiler as seen in Fig. 5 and 6 without the ratchet teeth. Fig. 11 is a modified view in perspective of the broiler raising and lowering and turning devices, the lower portion of the case or frame being broken away. Fig. 12 is a view of a modification of the broiler.

Similar numerals of reference indicate corresponding parts in all the figures of the drawing.

Referring to the drawings 20 indicatesa rectangular shaped case or frame composed of the

sides

21, 21 22,

22 and bottom 23, preferably constructed of thin metal. In the

end

22, 22 of the case at points equidistant from the

sides

21, 21 extending a short distance downwardly from the upper horizontal surfaces of said ends are oblong openings or slots 24, the

lower surfaces of which openings are curved in the arc of a circle.-

Upon the inner surfaces and ends of the case or frame are secured the horizontal broiler supporting flanges 25 which extend from the inner surfaces of one side of the box to the inner surfaces of the otherside and a slight distance below the line of the lower curved surfaces of the openings or slots 24.

Upon the inner surfaces of the

ends

21, 21 at points equi distant from the upper and lower horizontal surfaces ofjthe box-are horizontal flanges 26 of the same length as the flanges 25, the flanges upon one end 21 of the box being short in length as further described.

The flanges 26 support-a ventilating and fuel burning,

grate 27 extendingtransversely to the box and beneath which grate is a chamber 28 for smoke and vapor arising from the broiling of the meats or other food. In the side 21 of the box is an opening or flue 29 leading from the chamber 28 and upon thev outer surface of. said side extending around said opening is an annular flange or collar 30 and in which'collar as shown is fitted a flanged cover 31. The fuel burning and ventilating grate 27 consists ofpipes or burners 32 perforated at 52 upon their upper surfaces, said pipes extending from the.

inner surface of one end 22 nearly to the inner surface of the other end 22 and closed by suitable plugs 33 at each end. -A series of pipes or burners 32 are employed extending parallel with eaclnother. In the end'22 of the box opposite the ends of the pipes or burner 32am openings 35 through which extend the nipples 36 which are smaller in circumference than the pipes 32, the inner ends of which nipples extend through the plugs 33 a short distance within the pipes 32 and support said pipes detachably in position. Extending in the longitudinal direction of the pipes 32 and laterally from the opposite surfaces and in the line of the diameterof said pipes are short flanges 37 and from the outer surfaces of the flanges extend the plates or 'webs 38-, which plates are curved'in the arc of 'acircle and the upper'en'ds of which plates extend a short .distance above the line of the horizontal upper surfaces of thesaid pipes'and to a position a short distance from a vertical line extending through grate equi distant from said pipes thus forming between the outerlongitudinal surfaces of adjacent parallel plates 38 the-longitudinal slots or ventilating openings39; Upon -the ends of the plates 38 of the box are lugs 40 which rest upon the flanges 26.

The portions of the grate'adjaoent to the inner surface of the side 21 of the box'consist of narrow plates 41, supported upon the flanges 26, at one end and the end 21 of the box and also upon the short flanges 26 upon the end 22 of the box. In width these plates 41 extend from the inner surfaces of the sides of the box to within a short distance of the longitudinal outer surfaces of the plates 38 thus leaving a slot or opening of the same width as the slot or opening 39 between the suriaces of adjacent plates. Upon the outer ends of the nipples 36 are internally screw threaded caps 45, in which are ordinary cut off valves and with which valves are connected the valve stems 47 which extend through the said caps 45 and upon the outer ends'cf said stems are wheels or handles 48. With the lower surfaces of the sides of thecaps 45 are connected the upper endsoi short pipes 49 and with the lower end of one of saidzpipes is connected anelbow 50 and with thegother pipes the three way pipe connections 51 the elbow and one of said connections being connected by means of a shortlength of. pipes 52, the other connections 51- being connected by a short length of pipe 53. 54 indicates a gas supply pipe for gaseous fuel and is connected with the source of supplyat one end and with one of the three way connections 51 at the other end;

In the bottom 23 of the box is avlargecircular opening 42' in the sides of'which opening is fitted the annularflange 43 upon'the inner surface of the cover 44, which cover is larger than said opening and closes upon the outer surface of the bottom 23 of said box.

55 indicates the broiler-which consists of two frames between which'the meat is placed for the purpose of broilingor roasting, the details of construction of which broiler will be made the subject matter of a separate application. For thepurpose of illustration it will be observed the separate frames er the broiler com- I prise series of cross wires 55 upon which the articles are laid and that the frames'are mounted on the trunnions 56, the outer portions of the frames extending to within a short distance'jof the inner surfaces of the sides.2l of the boxthe lower flame resting upon the flanges 25 within the case and the outer ends of the trunnionsextend. through the slots 24 in the

ends

22, 22 of the case. Uponsaid outer end portions of the trunnions are wheels-.orhandles 57, The frames may be kept closed by awire'andhook 54.i 58 indicates the device or lever for raising and lowering the broiler which consists of-the

rocking bar

59 and 60 arranged in position near the upper portions'of the sides 21" and 21 of the case and'a short distance from the outer surfaces of the case. The ends of these'bars extend a slight distance beyond the line ofthe ends 22, 22 of the case. The bar 59 is connectedrwith the outer leaves of inverted hinges 61 arranged near the upper surface of the case, the inner leaves being secured rigidly to the case. With the outer ends of

thebars

59 and 60 are connected rigidly the lever arm-62 which extends parallel with the outer surface of the

ends

22, 22 of the case and are bent 1 in a downwardly curved line from the

bars

59 and 60 and below the line of the bottom of the slots 24 in the

ends

22, 22 of the case and also bent at both ends a slight degree inwardly. Connected rigidly withthe uppersurfaces ofv the curved lever arms 62 opposite the slots 2 4 are upwardly'extended plates 63 in which are'annularopenings or bearings 65 for the trunnions 56, supporting the broiler 55 in the upper portions of which plates are slots or openings 66, leading to the hearings or openings 65 which slots permit the passage ofthe trunnions. The trunnion supports or plates 63 as'shown are made intwo parts and riveted to the outer surfaces of the lever arms.

Upon the portion of the trunnions 56 extending beyond the flange 67 are ratchet teeth 68% seenlin'cross 'sectionin liig. 8 ,fthese teeth being made to extend in the opposite direction to the direction oi rotation of the trunnions 56. Upon the ends 22, 22 iof. the"box and extending at an angle to and located ashort distance irorn the sides ot-the slots 24 toward the'side 2'1 of'the case are the longitudinally grooved plates inwhich is a sliding pivot bolt'70 having 'a square shoulderflo Upon said bolt is a sleeve 70 having a shoulder 70 Upon the bolt 70 is a thunib screw 69*. The'lowerend, of a bar 71 fits over the sleeve 70 on the bolt 70. The other end of said bar extends upwardly a short distance and with which end is pivotally connected zit 72, the lower end of a short bar 73, Upon the upper end of the bar 73 is connected rigidly one side Cportion'jof :a U shaped trunnion grasping yoke hr jaw 74,. extending inwardly beyond the line of the lower surface oi the bar 73 and consistingof a plate bent in the arc ofa circle and extended about two thirds the distance in the direction'of the line of the circumferenceof the trunnion 56, a portion 74 of which U shaped portion extends laterally and inwardly and upon the "inner surface of whichjjaws are ratchet teeth. engaging with the ratchet teeth 68' upon the said trunnions. .Infthe outer curved surface of the plate 74 is a groove 74 which receives theflange 67. The sides of the opening 76 in plate 75 leading to the ratchet teeth are the proper distance apart {to'reg ister with the opening 66 in plate 63 ior the entrance oi the trunnions 56, the connection .of the plate 74 being made with the-plate 63. when the separate'parts are united with the bar 62. Whenthe trunnionsare 111-, troduced within the openings 66 and 76 thefra'tchet teeth on the trunnions engagewith the ratchet teeth 75 in plate 74, the broiler resting upon the flanges-25 in the case. Upon the outer free end of one of the, bars 62 supportingthe trunnion 56 is a handle 77.

In the side 21 of the case to which the-bar 59 is hinged and at a point equi distant-from theline of the

ends

22, 22 of the case isa vertical slot 78 which extendsfrom a point a short distance below-a line parallel with the under surface of the bar 59 and down wardly to a point above aline extending horizontally through the flanges 25. Upon the outer surface of the side 21 of the case below the lower end'of the slot is rigidly connected the lower end of aspring plate 79 the upper end of which plate is .bent inwardly within the slot 78, then bent at an angle toitseli andextended upwardly and outwardly from the upper portion of said slot forming a V shaped hook 'or 'spring catch80 the position'lof which is .just above one side of the lower frame or the broiler as seen in Fig. 3.

In the employment of the broiling apparatus the cover 31 is removed -irorn the flue opening 29 and the flange 30"connected with a pipe leading to an open fire place or chimney orother exitor draft opening for smoke. Gas-is admitted to theburners 32 by opening the valves 48. These burners 32 arelarger than the ni pples'46 thus adapting the apparatus to the use of either natural" orz'artificial hydro carbon gas which is admitted through the conducting pipe 54. In the employment of the former gas the grate 27 upon each side of the longitudinal slots 39 may lie covered with broken terra cotta or fire proof material which will absorb heat and radiate the same under low fire and the fire tempered so that the roasting may be gradual without liability of burning the gas permeating the material. During the roasting the draft upon the opening 29 acts to cause a down draft of the smoke and vapor and also. of the unconsumed gas which passes through the openings 39, into the chamber 28 and thence out of the chamber through the said opening and preventing the smoke and odors from entering the room and also preventing the deleterious action of gas on the meats. If preferred the cover 44-may be removed from the open ing 42 in the bottom 23 of the case and the case placed upon the stove or range, from which the cover has been removed and the opening 42 caused to register with the 7 opening in the range thus utilizing the natural draft of the stove or range to carry off the smoke. The drippings from the meat in broiling which will escape in some degree before the meat is seared will fall upon the flanges 38, the apertures 39 being above the hori- Zontal plane of the burner so that the down draft will not be impeded by clogging of the apertures. The drippings which fall upon the flanges are conducted to the upper surface of the flanges 37 in the heat of the burner and are carbonized the smoke passing through the apertures 39.

In order to raise the broiler 'from the supporting flanges 25 power is applied to the handle 77 and the frame 58 is raised upon its hinges 61 and at the-same time an initial start toward rotation of the broiler frames 55 is imparted by the spring hook 80 and the pivoted bars 71 and 73 are extended, the jaws simultaneously maintaining a rigid grasp upon the trunnions 56 of the broiler and causing rotary,movement to be imparted to said frame and upon the completion of the upward movement of the supporting lever arms 62 the

bars

71 and 7 3"are in line with each other the U shaped jaw 74 being in a reversed position with the opening 76, turned past the opening 66 in the bearing 63 and in a downward direction,thus locking the trunnions and the broiler frames in the meantime being also in a reversed position for exposing other portions of the mcatto the fire the position of the jaw 74 being such as to prevent the dislodgement of the trunnions from the raising and lowering frame and the U shaped journal bearings '63. When the broiler is lowered in position the openings 66 on the journal bearing and the openings 7 6 to the jaws 74 register with each other and in which position the trunnions on the broiler may be raised out of the said openings. In lowering the frame 58 with the broiler the ratchet 75 upon plate 74 and the ratchet teeth 68 on the trunnions 56 slip past each other and the broiler frame moves downwardly tothe position for roasting as before. The lever arms 62 rest at all times upon the pivot bolt 70 and may be raised and lowered to adjust the height of the bar 71 to the height necessitated by the trunnions 56 by thumb screw 70 Instead of frame 58 for raising and lowering the broiler I may employ the modified construction as seen in Fig. 11. The case 81 as seen in said'figure. is sub-.

spring catch 84. This rod extends a short distance beyond the ends 83 of the case' and is fulcrumed or journaled in the brackets 86 which are connected with the said ends 83 of the case the upper ends of the bracket being inclined a slight distance outwardly and beyond. the upper outwardly inclined portion of the sides 82 of the case. The ends of the rod 85 are bent at right angles to form lever arms and extended to a position opposite the openings 87 in the ends of the case which openings are the same as the openings 24 in Fig. 1'. Said ends of the rods are bent upwardly and extended rearwardly a short distance in the arc of a circle as at 88. Upon the upper surface of the said ends'of the rods adjacent to the bent portion 88 are ratchet teeth 89. The trunnions 90 of the broiler are held between spring clips 91 consisting of a plate extending in an arc of a circle on 'Upon the trunnions are ratchet teeth 92 as in Fig. 1 which engage with the ratchet teeth upon the ends of the lever arms on rods 85. Upon the rod is a short arm 93 upon which is a detachable handle 94. Connected pivotally at one end with the portion of the clips 91 on the ends of lever arms on rod 85 are rods 95 the other ends of which rods are extended forwardly and connected pivotally with the ends 83 of the case near the parallel side 82 of the case. The broiler is raised repeatedly in this modification by the power applied to the handle or arm 94 inwhich'movement the clip 91 supporting the trunnions 90 move in opposite directions, the teeth upon the rod obtaining a grasp upon the ratchet teeth upon the trunnions 90 in each forward movement of the clips and imparting rotation to the trunnions 90, the bendingof the,upper portions of the sides of the box outwardly affords space for the movement of the frame of-the broiler. In the repeated movements upwardly and downwardly of the broiler frame the portion'of the frame toward the side 82 comes forcibly into contact with the spring plate 84 and upper surface of the hooks obtaining in each impact an initial movement upwardly to assist the rotation of the trunnions by the ratchet teeth.

The ratchet teeth upon the jaw 74 as in Fig. 1 may be dispensed with if desired and the surface left smooth as seen in Figs. 10 and 10 In this construction the jaw 96 will obtain a fractional grasp upon the trunnions which as shown in Fig. 9 in section will be made with corresponding frictional surfaces. I

It is obvious that instead of the broiler frames as shown an ordinary spit may be employed of which the trunnions will form an integral part as seen in Fig. .12

' in which 97' is the spit 98 the trunnions rotation being imparted to thespit as the spit is raised in position in corresponding manner with the rotation of the broiler frames. The spring plate 79 may be dispensed with and such other modifications employed as are within the scope of the invention.
