(ci. iacp-1) This invention relates to cooking ranges particularly adapted for camp and` garrison use and for ready transportation from one point to another to feed a large body of men.

It is onefof the objects of the invention toprovide a cooking range, which is peculiarly adaptable for army use or-camp use and which can be transported as by 'truck from one location to another and which will be exceedingly strong and rugged to withstand rough handling and transportation.

Another object is to provide sucha cooking range, which is adaptable for operation through use of different 'types of fuel such as may be available at different locations and under varying circumstances.

- More specifically, itis one of the objects of the invention to provide a cooking range which includes a skeleton frame of great strength and cooking compartments Vand burners located completely within the outline of the skeleton frame, whereby the skeleton vframe will act asa buffer for the burners and cooking compartments to prevent injury thereto during rough handling in 'D moving the range from one location to another.

Another more Vspecific object is to provide a cooking range, which can be utilized successfully with gasoline, Woo-d, or gas as a fuel.

The objects and advantages of the invention will more fully appear from the following description made in connection with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the various views,'and in which, V

Generally stated, the cooking range of the invention includes a skeleton frame designated generally-by the letter A, an oven section designated generally by the letter B, cooker sections, three of which are shown in the present embodiment, designated generally by the letter C and a compartment section designated generally by the letter D. Of course, the number of oven sections B and cooker sections C incorporated in the range may be varied as desired Vaccording to the requirements of the range. l

The skeleton frame A, as best shown in Fig. 2, consists in reality of a pair of heavy, vertical,

front and rear upright longitudinal frames spaced from each other and interconnected by a number of transverse cross bars. The longitudinal frames each include upper and lower horizontal rails I3 and Il respectively interconnected by vertical corner rails I5,- intermediate rails IB and I1 and intermediate bars I8. The front left corner rail I5 is interconnected with the rail I6 of the front longitudinal frame by a horizontal rail I9, while the rails I8 and I1 of both front and rear framesI are interconnected by horizontal rails spaced a short distance above the rails I4. The rails i6 and Il of the rear longitudinal frame are interconnected by a horizontal bar 2I locatedI a short distance below the top horizontal rail I3 of this same frame. Theleft hand rail I5 of the front frame is connected to the rail I6 thereof by a horizontal bar 22 attached to the inner sides of the said rails I5 and I6, this'bar 22 being spaced somewhat above therail I 9. At .the same level as the bar 22, a bar 23 interconnects the left hand corner rail I5 of the rear frame .with the rail I6 thereof. U-shaped rails 24 forming the supports or legs-for the cooking range are conrear longitudinal frames of the skeleton frame A include a pair of bars 2i attached to and extending between the two bars 22 and 23-above the same, onev of which bars 2l is located adjacent the corner rails Il and the other of whichbars 2l is located adjacent the rails I.. Also among the said transverse bars are bars 2l resting on,

extending between and connecting the two rails 2l, one of these bars 2l being located` adjacent rails I1, others being located adjacent bars i8 and another being located adjacent rails I1. Bar 2| of the rear longitudinal frame is connected to the front longitudinal frame by horizontal bars 21. The various bars and rails composing the skeleton frame are preferably welded or otherwise secured together to form for all intents and purposes a unitary frame'of great strength and rigidity. The various rails I3, I4, i5, IB, I1, I9, and 24 in the form of the device illustrated, are shown as being of T-bar construction and the outer ones of these rails have their central webs directed inwardly so as to present flat outer surfaces. The bars 2l, 22, 23, 25, 2l and 21 in the form of the device illustrated, are shown as being of angle bar construction and among these bars, bars 25, 26 and 21 are arranged in pairs in oppositely facing relation. Of course, the detailed construction of the skeleton frame can be varied considerably as desired. y

The oven section B of the range is defined in outline by those portions of the skeleton frame A extending longitudinally of the skeleton frame between the left hand corner rails I5 and the rails I0, extending vertically of the skeleton frame between rails I4 and rails i2 and extending transversely of the skeleton frame between the front longitudinal frame and the rear longitudinal frame thereof. Within these outlines the oven itself and the oven burners are located. The oven section is closed at its bottom by a bottom panel 28, is closed at its sides by side panels 2l and is closed at its back by a back panel I0. Extending between and resting on the cross bars are a plurality of longitudinally extending channels II which are assembled in engaging relation with their channels facing upwardly. Within these channels 2l are located fillers 22 formed of asbestos or analogous material which will assist in preventing the burning out of the channels and in disseminating even heat through the bottom of the oven. overlying the filled channels 2| is a plate'll. The channels Il, llers l2 and plate `22 form the bottom of the oven proper and serve as a base upon which normally rests a grating 24 consisting of a number of spaced rods having their ends secured to and embedded within three or any number of transversely extending bars. Above the bars 25 a vertical panel 35 extends between bar 23 and the upper rail I2 oi' the back. frame to form a back for the` oven, while in like manner upwardly projecting side panels 3i extend from the bars 25 upwardly to form the sides of the oven proper. Panel II is spaced from the panel 3l to form an air channel, the purpose of which will presently appear, while in similar manner panels 36 are spaced from the side panels 29 to aiford channels between the sides of the oven proper and-the side panels 2|. The upper edges of panels It and 2l are reversely bent as best shown in Fig. 3, to permit of overlapping engagement.

The chamber in the oven section B below the oven bottom forms a burner and broiler compartment. as best shown in Fig. 6. A burner designated as an entirety by the letter E is supported within the said compartment' above the level of rail' Il by means of straps 21 attached at their ends to the cross bars 2i. A lower front closure plate 2l for the oven section is provided which fits between the lower rail Il of the front frame and the rail I0 and extends from the left front corner rail Il to the front rail I.. The space between rail I! and bar 22 ls normally partially closed by a removable intermediate closure plate 29. this plate having a central opening therein for access to thevalve handles of the burner E. 'Ihe front of the oven is normally closed by an oven door Il pivotally connected near its lower edge to the adjacent rails I5 and I0 of the skeleton frame by pivot studs ll. This oven door has pivotally connected thereto a pair of stop bars 42, as best shown in Figs. 5 and 6, and these stop bars work between the side panels Il of the oven and the side panels 2! of the oven section and extend through slots formed in the inner webs of the front left rail II and the front rail Il and in the forwardedges ofv panels 2l and 2l. Stop bars 42 have angularly bent inner ends which engage with the forward portions of the panels 38 when the oven door is swung downwardly to a horizontal position to retain the door in this position. To releasably connect panel 38 and oven door Il at their upper edges with the adjacent rails of the skeleton frame. latches I2 are provided having removable handles 44. Inasmuch as a number of similar latches are provided for other panels of the range, the detailed construction of these latches will be hereafter described.

A lid 4l is provided for closing the top of the oven section of the range. This lid consists of a shallow box-like casing having projecting flanges at its top which normally rest upon the rails I2 and the upper edges of the side panels 2l. To permit the exhaust of the waste products of combustion from the oven section B. the back panel is provided with a series of spaced apertures 30a near its upper edge. Also the side panels 20 of the oven are equipped with a series of apertures a near their upper ends, while the adjacent ends of the box of lid 45 are equipped with a series of apertures "a and the back wall of the box of the lid 4l is equipped with a series.

of apertures 45h. The back panel 35 of the oven is also equipped with a series of spaced apertures 25a near its upper end. 'Ihe waste products of combustion from the burner E in the oven section B take paths upwardly and about the side walls and the back wall l5 of the oven. In other words, some of the products of combustion run'upwardly through the channel between panels M and 25 and exhaust to atmosphere through the apertures 20a. Other products of combustion run upwardly from the burner E through the channels between side panels 20 and 2.9, pass inwardly through apertures 38a and apertures 45a into the box-compartment of lid l5 and thence travel rearwardly through apertures 45h and 35a to exhaust to atmosphere through apertures 20a. The products of combustion in addition to heating the bottom of the-oven thus heat the side walls and the back of the oven as well, so as to cause uniformdlstribution of heat to the oven.

Preferably the side panels 56 of the oven are equipped with oppositely opposed grille slides 45 lor receiving the oven grille 54. For reception within the oven there is provided a large cooking vessel 41 having a lid 41a. 'To tightly secure thecooking vessel 41 in place as when thecooking range is being transported, a clamping bar 40 is provided having ends adapted to be received within slots 36h adjacent the upper ends of the spring action of the clamping bar 48, while at the same time retaining the cooking vessel 41 against sliding movement through engagement of the bar 4I with opposite portions o! the edge of the vessel.

The cooker sections C of thevra'nge are defined in outlini? by those portions of the skeleton frame A extending longitudinally of the frame between rails I6 and I1, extending vertically of the-frame between rails I4 and I3 and extending transverse- Aly of the skeleton frame between the front longitudinal frame and the rear longitudinal frame thereof. Theleft hand cookersection C extends 4 longitudinally oi' the skeleton frame between rails I6 and the left hand bars I8; the middle cooker section C extends longitudinally o1 the skeleton frame between the left hand bars I 8 and the right hand bars I8 and the right hand cooker section C extends longitudinally oi the frame between the right hand bars I8 and the right'hand rails I1. 'I'he various cooker sections communicate .one with the other and are generally of similar construction.

Each cooker section C is provided with a bottom 50, a back panel I extending from the rear rail to the rear rail I3, and a back panel4 52 extending from the rear rail I4 to the rear rail 20. Burners E are supported by straps 53 in the lower portions of each cooker section, the straps being secured at their upper ends to the cross bars 26. The burner part of each cooker section is closed at its frontv by a removable panel 54 on the same order as panel 39 previously reierred to and having a central opening therein to permit access to the various valve handlesof a burner E. I'he front of each cooker section above the front rail 20 is closed by a removable front panel 55 equipped near its upper end with a latch 43 having a removable handle 44 similar to the previously described latch. Panel 55 has an opening 55a therein near its lower edge and this opening is adapted to be closed to a desired degree by means of a sliding damper plate 56 inwardly disposed from panel 65 and having, as

best shown in Fig. 4, an upwardly projecting 'shank 56a to which issecured a nut 51. A knob 58 carries a stud which projects through the shank 56a and cooperates with the nut 51, the

front panel 55 having a vertical slot 55h therein for receiving the stud and permitting upward and downward movement of the knob 58. With this structure, knob 58 may be loosened f rom its nut 51 whereupon by pressing upwardly or downwardly on the knob 58 the damper plate 56 can be raised or lowered to expose the opening 55a to the desired extent and the knob 58 can then be turned so as to tightly clamp the panel 55 between the shank 56a and the knob. The damper project down through an plate Il win then be heldin the desired adjusted position. 'I'he lower ,edges of the panels 55 are prefere ably provided with projections 55e `which are received within small openings 20a providedin the rails 2l. vIn similar manner, the panels 54 are provided with projections 54a.at their lower edges received within openings I4a provided in the frontrail I4. To secure the upper edges oi the panels 54 in place, spring pressed pins mountedin wells 60 attached to the upper edges of the panels v54 are provided, these pins cooperating with openl ings in the front rail 20. It should here perhaps be stated that the panel 39 of the oven section' B is removably 'held in place in similar manner to the panels54 and that the lower edge of the panel 38 of -the oven section is held in place on the front rail I4ln the same manner as are the lower edges of the p'anels 55 held in place on' the front rail 28. i l" N The tops oi' the three cooker sections are closed by a single lid 6I which carries a downwardly projectingskirt spaced from its peripheral edges. 'This lid is preferably braced by cross brace members 62 and the back part oi' the skirt is provided with a plurality of spacediapertures 6Ia to prevent the fumes arising from the burners from being caught and held by the skirt. 'Ihe waste products of combustion from the burners may ex.- haust to atmosphere from the cooker compartments C through a plurality of spaced' apertures 5Ia provided in the back panels 5I 'near their upper edges. U

A cooking vessel 63 for each 'cooker section C is provided and each cooking vessel is equipped with a removable lid 63a. These cooking vessels 63, as shown in full lines, Fig. 4, and as also shown in Fig. 3, are normally carried by pairs of cross bars 26 and they are of such height that they canbe removed -from the'cooker sections C when the iront panels 55 thereof are removed.

For holding the cooking vessel 63 in place, during movement of the cooking range from one posi-n-1' e tion to another, as well as for securely clamping the lids 63a in position, a clamping bar 64 is provided Which has portions adapted to be received below the forwardly projecting parts oi angular brackets 65 attached to the central cross bars 21. Each 4latch bar 64 is of such length that when applied in overlying relation relative to the cooking vessels 63, end portions of the bar will rest against handles 63h attached to the lids 63a. The latch bar 64, as best. shown in Fig. 8, is formed of spring metal and has upwardly projecting central lugs 64a within which a clamping dog 66 is pivoted. Clamping dog 66 has a tongue which may project down through an opening in the central part of the clamping bar 64 as the dog is swung from the full line position shown in Fig. Sto the dotted line position there shown, and this dog will bear against the handle 63h of the central cooking vessel 63 to distort the clamp- Ling bar, as shown in Fig. 3, to firmly and securely wood to be placed therein. When the flrepots 61 are used, they will be supported upon the cross forms the exterior sections C, all panels. burners. etc.. within these heated. by a supply from to the supply line 1l.

The damper plates Il are usefulinregulating the draftof air to the nrepots when they are used. f course, to put the wood nrepots l1 in position for use, it isnecesaarytoilrstremovethefrontpanels Il. v It should be noted that the skeleton frame A outline for the three cooker cooker sections being protected by skeleton frame. v y

The compartment section D is defined in outline by those portions of the skeleton frame A extending longitudinally of the frame between lthe rails i1 and the right hand corner rails il, extending vertically of the skeleton frame between rails Il and rails il and extending transversely of the skeleton frame between the front longitudinal frame and the rear longitudinal frame thereof. The compartment .section includes a bottom Il. side walls il and front and A skiried lid'1l closes the top of the compartment section. Mounted within the compartment section is a liquid fuel tank 12 adapted to hold hydrocarbon fuel such as gasoline under air pressure. This tank is equipped with the usual nller opening closed by a cap 12a and it is also provided with the usual check valve equipped nipple 12b to which a hose from an air pump may be attached for applying 'airpressuretothetank Heavy cross handles 18 are attached to the ends of the range, these handles being secured to the corner rails Ii of the skeleton frame. By mans of these handles the range can be readily moved from one position to another. The various lids Il, li and 1i are all equipped -with wells within which handles 1l are pivotally mounted whereby the lids'can be readily manipulated.

To supply the burners E with gasoline .or such other liquid hydrocarbon fuel as may be desired, and to permit instant lighting of the burners, without pre-generation, by a supply of for example air and gasoline. as well as to permit continued operation of the burners, after they are of liquid fuel such as gasotwo fuel lines and 18 are provided running from the tank 1I to points adjacent the various burners E. An instantly ignitable mixture of air and gasoline is supplied through the line 1l while gasoline alone is supplied through in the embodiment illustrated. Mounted on the tank 1I is a valve iltting 11 connected'to the line 1l. From this fitting a short air tube 1l extends downwardly into the air space line,

' of the tank and terminates in a measured orince through which air may be admitted to the fitting 11. this air being controlled by a valve 1l mounted in valve fitting 11.v Also projecting downwardly into the tank from valve ntting 11 is a gasoline tube Il which projects downwardly to a point near the bottom of the tank within the liquid space thereof and at the said point the gasoline tube Il is provided with a measured orifice for the admission of gasoline thereto. A valve Il mounted in the valve fitting 11 controls the ilow of gasoline through tube Il. Air and gasoline are mixed in the fitting 11 in proper quantities for instant ignition and run therel! is mounted on the top of the tank and connects withsupply line". A gasoline tube Il connected to this fitting extends downwardly Another valve fitting therefromtoa point nearthebottosnofthetank within the liquid space thereof and this gasoline tubeis provided at its lower end with a measured orifice through which gasoline is admitted to the tube. A valve M mounted in the fitting I! controls theilow of gasoline through the tube al. Gasoline alone is supplied to the line 1t from the tube Il.

Lines 1l and 1i have-branches which run upwardly to shutoff valves Il and Il respectively for each burnerli. From the shut-oi! valves ll and Il, conduits I1 and Il respectively run and these conduits are-connected to a three-way ntting Il carried by a sleeve-like portion Il of a burner E. The three-way fitting Il of each burner communicates through a nipple, not illustrated. with a generator tube Il. the nipple being heldin tight engagement with an apertured port ofthe generator tube of a set screw Il. in accordance with the usual practice.

The particular burner E illustrated forms the subject matter of a separate invention and, therefore, need not be described in detail here. It suffices to say that the generator tube Il at its inner end loosely ilts throwh an opening in a mixing chamber Il and within this chamber the ,tube is provided with an orifice from which the gas from the generator tube Il elects into the mixing chamber. Air is admitted to the mix- -ing chamber through an opening M. best shown in Fig. 4, and the air and gas from the generator tube Il mix in the mixing chamber Il and are conveyed therefrom through hollow branches of the burner to various burner heads 0l, Il and l1. The burner head l1 is located below a portion of the generator tube Il, so as to play thereon an'd thereby heat the tube to generate gasoline supplied thereto into gas. The burners E are of such type as-to burn either ordinary gasoline or gasoline containing tetraethyl lead. But by substitution of a slightly different type of pipe for generator tube il, it is possible to burn either natural or artincial gas 'in the burners E.

To permit natural or artincial gas to be burned in the range, the range may be set up as shown in Figs. l2 and 13. A gas conduit Il may be applied to the range by mounting the same in brackets 8l attached respectively as to the front left hand corner ra II, the front rail it and the right hand front bar ll. these brackets being attachable to the respective rails and bars after the panels Il and Il have been removed. Branch pipes ill equipped with valves ill are connected to the conduit Il adjacent the various burners and'these pipes Ill are substituted for the generator tubes li. Of course, these pipes l Il have no communication with the threcway fittings 8l but otherwise they differ very little from the generator tubes with the exception that their outlet ports received within the mixing chambers Il of the burners E are larger than the small orifices found in the generator tubes il.

In Figs. 10 and 11, the detailed construction of a latch applied to the panels Il is illustrated. The latches applied to panel Il and panel Il are of similar construction with the exception that latch applied to panel 4l differs slightly as to detail. As shown in Pigs. 10 and 11. each latch la is o'f'cylindrical construction and carries a latching finger and has an outer end trunnione and Journaled in its mounting panel. In the caseofallthelatchesexceptthelatchapplied tothe doorpanelll.the other endof thelatch is trunnioned and received within a strap |02 secured to' the mounting panel at the inner side thereof. 'I'he outer trunnioned end of each latch projects through an opening in the mounting panel and the latch is bored and internally screw threaded to receive a knob headed screw |03 which releasably connects the handle 44 to the latch 43. The outer end of the latch is prol vided with a pyramid-shaped recess running into the screw opening of the latch to receive a corresponding projection on the handle 44. The outer end of the latch terminates flush with the outer surface of the panel to which the latch is applied so that when the handle 44 is removed by unscrewing the screw |03, no portion of the latch projects beyond the outline of the skeleton frame of the range. The particular latch 43 applied to the door 40 differs from the remaining latches only in that an inner portion of this particular latch is journaled in the inner section of the roven door 40 rather than in a strap |02 applied to the door, the construction of this oven door latch being illustrated in Fig. 6.

Of course, knobs 58 for the damper plates 56 may be removed and as brackets 99 for the gas conduit 90 may be readily removed and as latch handles 44 may be readily removed, all parts of the range projecting at the front beyond the outline of the skeleton frame may be removed whenever it is desired to transport the range` from one location to another. When the range is to be transported these parts are, of course, removed, the wood grates 61 are removed and the latching bars 64 and 48 are applied in position to secure the various cooking vessels 41 and 63 and the lids thereof in position, as best shown in Fig. 3. The skeleton frame A, together with the handles 13 then fully protect the Various parts of the range, such as the burners E, oven and the various panels, so as to prevent injury thereto during rough handling of the range. All parts of the range fall within the vertical outlines. of the skeleton frame A with the exception of the heavy handles 13 and the skeleton frame acts as a buffer to prevent injury to other parts of the range. Inasmuch as the supports 24 are longitudinally spaced from each other, so as to form in reality a recess in the lower part of the range between the left hand supports and the right hand supports 24, the range can be readily placed upon a truck having upwardly curved rear wheel wells or projections and the supports 24 will rest on the truck bottom. The range can thus be very easily moved from one position to another without danger of injury and is highly adaptable for army and camp use for this reason.

In utilizing the range with gasoline as the cooking fuel, the range will be set up as shown in Fig. 3. Tank 12 havingbeen partially filled with gasoline and air pressure having been applied to the tank and the generator tubes 9| being in position, the range is ready for use. To light one of the burners E, valves 19 and 8| being previously opened, it becomes only necessary to open the valve of that burner and apply a match to the burner. A mixture of air and gasoline is then supplied to the generator tube 4 9| of the burner E to be utilized and this mixture opened, whereupon the burner will continue in operation under liquid gasoline alone without exhausting air from the tank4 12.

When it is desired to operate the cooker sections C using wood, coal or the like, as fuel, the wood repots 61 will be placed in position, as shown in Fig. 1, and the cooking vessels 63, will be located as shown in dotted lines Fig. 4 over the repots. The damper plates 56 will then be raised to afford proper draft and wood res or coal fires or fires from any other type of solid lfuel may be kindled in the repots.

When it is desired, as for garrison use where natural or artificial gas is available as fuel, to use the range, the range can be set up as shown in Fig. 12 by applying the gas conduit 98, brackets 99, gas pipes |00 and valves |0|. The range will then be used as an ordinary gas stove after connection of conduit 98 to the gas supply is made.

It will be seen that an exceedingly strong and durable cooking range has been provided, which can be utilized with different types of fuel for cooking food to feed a large body of men. While the range is particularly adapted for army use in the field and in the garrison, it is also capable of being used anywhere where food is to be prepared for a large number o1 people. Inasmuch as the cooking vessels 63 and 41 are accessible from the top of the range, when the lids 6|, 63a, 45 and 41a are removed, the various cooking vessels may be left in place within the range while food is being dispensed from the cooking vessels and the food within the cooking .essels may be kept warm while food is being dispensed therefrom.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the Various parts r without departing from the scope of the present invention, which generally stated consists in the matter shown and described and set forth in the appended claims.
