may concern. Be it known that I, AMES L. CARBnRY, a. citizen of the United States, residing at Rockhill, in the county of York and State of South Carolina, have invented certain I new f and useful Iinprov'einents in stem Cooking Apparatus, of whichthe following is a specification. Y i f 7 My inventionrelates to steam cookers for sterilizing or processing fruits, vegetables or other food stuffs and has particular ref erence to such cookers of the closedfor sealed type, wherein, different desired degrees of minimum.

steam pressure may be obtained, for provide.

ing corresponding degrees of heat, and the elements of danger, such as explosions or other similar accidents are reduced to the [A11 importantv object of this inventionis to provide means of thelabove mentioned character, which will reduce the time re-, quired for preserving fruits, vegetables and ,the like and increase the'iminunityiofthe same from subsequent deterioration onspoiling, due to action 'ofunkilledbacteria, fungi, I

spores of the same. v r

A further Object of t tion is a.

provide a steam cooker of the abovefnienQv tioned character, which is so" constructed that the bottles, cans, or other receptacles, containing the material to be preserved,niay

be quickly and easily moved into faiid out of the same.

I liable in operation.

c Other; objects and advantages of this irivention will; be apparent during the course provide a steam'cooker of the. above mentioned character, which is'siinplej in corn struction', cheap to manufacture, andre of the following, description.

In the drawings, wherein forth'e sake of illustration is [shown a preferred enibodiment of my invention, the numeral 6 designates a main shell orcasing, forming the body portion of the apparatus. Theflower end of the main shell 6 is closed by a bottom 7, as shown.

i 5 main shell 6 constitutes a processing or cooking chamber, The rear endcf the main?" ,shellfi.is provided with an opening f), the, .walls 10 of which are preferably jslightly beveled or bent inwardly, for eiigagi'rigfw,ith v a door 11, the-:free edges of which are bev-w r eled or bentf outwardly, as shown; This, door 15 connected with the main shellQG to swing in a horizontal 13laI18,."l11621Il S 0 f hinges12, Connected with the .doorl-l is a swinging latch 13, to engagel a fixed catch 14 carried, by the inain shell, 6, as shown. "The swinging latch 13 engages the verti-. ically inclined face 15 of thefixed catchle,

whereby upon the downward movement of the lat'ch13 within the I fixed catch 14:, the swinging latch will force the door '11 inwardly into firm engagement with the walls of theopemng 9, for forming therewith a substantially steain tight joint. The'door 11 is preferably provided upon its engaging in inner surface with a sheet of packing 16.

Disposed within vthe nain shell 6 arev I spacedfhorizontal guide. rodsor rails 17,

which are rigidly connected with jthe sides oftheinain-shell. These f g'uid'e rods or rails are preferably L-shaped in cross-section and are spaced fromthe bottom 7 ofthe cham; ber 8, to be adjacentthe lower end of the 5. opening 9. Adaptedtotravel or slide long'itudinally upon the rails' l 7 is acarriage,

riage, caror d'rawer l8 is provided with a ine A car orffdrawer l8 arefixed horizontalcrails 'or"guide redslfi, engaged by a transverse striporbar 18, attached to; one endof. the T carriage 18. The function of this constructioniis toprevent the tilting of the carriage,

car or dr'awer when partly withdrawn from the main shell 6. Pivot'ajlly connected with position and horizontally *arranged when the carriage is moved into the mainshell, as

the bottom of the carriage, car or drawer -18 is 'afsupportin'g leg 19 ,which is vertically.

disposed when thecarriage is in its .outer I shown Any suitable means may be employed tosupport the free end of the leg 19, when the same is horizontally arranged.

The lower portion of the main shell, 6 beneath the rails '17 constitutes a water holding chamber 21. The water is supplied to the chamber 21 from a tank 22, whichis disposed exteriorily of the main shell 6 and suitably connected therewith, as shown. Connectedwith thelower end of the tank 22 is an outlet pipe 23," extending into the chamber 21. Within thischamber the out-l let pipe--23 is provided with a valve 2%, opererated by 'apivoted-lever-25, which is moved by a' iioat 26. When the level of the water within the chamber 21 falls below a certain point, the float 26is lowered whereby the valve2 1 is opened to supply the water to the inunication between the upper portion fofthe chamber until the desired level is regained. At its upper end,the tank 22 is provided with an inlet pipe 27, carrying a removable cap 28. A pipe29 serves to establish coinmain shell 6 or the cooking chamber and the upper end of the tank 22, whereby the pressure "above'andbelow the water 'withm the tank 22, is balanced.

The numeralBO designates a furnace shell or the like. One end of the furnace shell is provided with a fuel opening 31f,'which* is normally closed by apreferably horizontally swinging door 32. Thisdoor is held in its closed osition b latchmeans 3S and isalso preferably provided with damper At its opposite end the furnace-shell S0 is provided with an outlet opening discharging into an upstanding stack 2-36. This stack is connected with the tankt22 by'horizontal from its opposite "ends with upstanding "tubes 39,,cove redby fusible" caps 10. Tl1ese I 21; It is thus seen that should the valve 24:

andvertical' strap irons 37 and 38, as shown. V

The stack is ded with damper 36 The bottom 4 is provided near and spaced caps are to be ana mia suitable metal that will fuse'when the heat within the shell. (3 exceeds a certain degree, due tofthe very" low level of the water within the chamber and float means for operating the" same, for

any reason, become inoperativefso that the water level within the chamber 21 should drop below the danger point, the caps 4L0 will fuse, whereby the steam pressure will be released and the remaining water and steam discharged intothe furnace shell 30 for'extinguishing the fire. The function in providing two of the. fusiblecaps 4L0 disposed near and spaced from the opposite end of the main shell 6, is to provide means which willoperate satisfactorily when the main shell 6 is horizontally disposed or inclineda I provide a safety valve structure 42 for regulating the pressure of steam maintained within the shell 6.

; The operation of the apparatus is as follows: The material to be preserved is put up ;in jars, cans or other receptacles, whiclrare placed in baskets, whichin turn are placed within the carriage 18. A suitable fire" is built within the furnace shell 30, which boils ;the water in the chamber 21, for generating thesteam', which in turn cooks the material to be preserved. The valve structure a2 is normally closed and is adapted to quickly reduce the pressure within the apparatus, when opened. To maintain constant the water level in chamber 21, I provide the float ioperated valve which automatically operates for withdrawing the water as needed from the tank 22, and supplying the same to the chamber 21.

It is to beunderstood that the form ofmy invention, herewith shown and described is to be taken as a preferred example ofthe same, and that certain changes in'the shape, slze and arrangement of parts may be resorted to withoutdeparting from the spirit of the invention or the scope of the sub joined claims.
