SMOKEHOUSE.

Application filed April 2 5, 1927. Serial No. 186,336.

This invention relates to improvements in smoke houses, particularly ofthe type employed for curing meat, fish and like-commodities by subjecting the same to a dense smoke or smudge from suitable combustibles, and aims primarily to providea smoke house especially designed to use any kind of fuel for maintaining a smudge to cure the commodity placed therein and wherefrom the noxious combustion products of the fuel are carried 0H without contacting withor contaminating such commodity.

Contemplated by the present invention is a smoke house embodying 'a combustion chamber or fire box; a smudge chamber separated andsealed from said fire box; a curing or smoking chamber for the commodities to be cured communicating with said smudge chamber; a grating or grille separating the smudge and curing chambers; a fiue for combustion products leading upwardly from the combustion chamber through the smudge chamber; a transversely disposed super-heatingflue wherewith the combustion chamber "flue is connected which'extends through and projects at one end thereof from the smudge chamber; a flue for the smoke from the smudge chamber leading from the upper end of the curing chamber; means for supporting within the curingc-ha'mber the commodities to be treated; and means to permit of rapid and ready access to the several chambers of the smoke house, all of which are important features of the invention and are to 'be'correlated in the broad aim of enhancing the 'efficiency of the apparatus for general use.

The above,and additional features and objects which will be more specifically treated are attainedby such means as are shown in the accompanying drawings, described in the following specification and then more clear- 1y pointed out in the claims, which are appended hereto and form'part of this application. 1

WVith reference to the drawings, in Which there is illustrated one embodiment of the invention, and throughout the several views of which like characters of reference designate similar parts:

' Figure 1 is a longitudinal vertical medial section of a smoke house comprehended by the present invention, and

Fig. 2 is a fragmentary vertical transverse section of the same taken through 22 of way of illustration.

Fig. 1, certain parts thereof being shown' in elevation for clarity of illustration.

Beforetakin-g up the detailed description of the drawings, a general exposition of the specific purposes, functions and advantages of the smoke house evolved by the present in ventlon will be undertaken, which, while it is primarily and especially designedf'forsmoking or curing meat and fish is also adaptableand suitable for treating other commodities in a like manner when necessary or desired." Heretofore, it has been customary in fabricating a smoke house-toconstr uct the same with a common smudge and curing chamber only, which necessitated burning fuel having no noxiousfumes or gases to contaminate the commodity being cured, actual experience has demonstrated in many in.- stances that such methods are inconvenient, wasteful and ineflicient. Wherefore, it is a primary object of p the present invention to fabricate a smoke house-having afire box or combustion chamber separated and sealed from the intercommunicating smudge and curing chambers thereof, wherein any kind of fuel may'be burned such as coke, coal, oil, gas or the llke, for 1gn1t1ng and maintaining a smudgeof suitable combustibles within said smudge chamber, and wherefrom thenoxious gases or fumes from said fuels are carried off- 111 such a manner as to prevent the same from coming in contact with the commodity being treated in order that the latter may not be contaminated 01" detrimentally affected thereby, aswill be manifest and apparent; A further and essentially important feature of the present invention is to produce and'maintain asmokehouse smudge in a more convenient, economical and efiicient manner than has'heretofore been attamed. In the present instance the smoke house "disclosed" is equipped with oil burning apparatus, but, it

is to be understood that other fuels maybe used, without departing from the spirit. of

the invention or the benefits-derivable there A from, the present showing being merely by jBeginning the more detailed description of the apparatus by reference to the drawing,

are supported or rest upon the basement floor 4 andlextend upwardly therefrom through the main floor 5, and inasmuch as: the smoke houses are identical in construction, a description of one. will sufiice for all.

The smoke house 6 is sub-divided into a-se ries of chambers comprising a brick-lined combustion chamber or fire box 7, a smudge chamber 8 and a curing or smokingchamber 9. The combustion chamber 7 and smudge chamber 8.are separated from-each otherby a horizontallydisposed brick-wall 10or=bya metal =.plate and, to effiect a positive sealing andaseparationof such-chambers from each other, a layer of fire cement 1.l is spread upon the upper surface-of the separatingwall 10, whereat italso serves and functions-as a floor I for the-smudge-cha1nberi8.

-Moun-ted:upon1 the forward wallof the combustion chamber 7 in any convenient manner-is an oil burner 12, ofrany well known type, the diseh-argenozzle or burner tip 13 of which extends: into said combustion chamber throughhan aperture llformed in said ilorthrough-"the smudge chamber Sand iitsupper end is: curved forwardly and rigidly connected :to an enlarged transversely disposed fiue{16', wl1-ieh extendsthrouglrand is-:common to allof thesmudge chambersof the seriesyof.smoke -houses, saidfl'ue 16. beingprimarily. designed .and intended to; utilize the heat of; the.:combustiony products passing therethrough for superb-eating; the-- smudge chamber 8: and materially increasing the temperature of. tlie curing; chambers .associated thGI'G'lVlthJ The discharge end of the fine 16 extends beyond'ztherend smudge chamber. 8 of the series. and is connected to a chimney, not showin -'bviously-,rtherefore, the

An -opening *18formed in! the forward wall of the smudge chamber 8 and normally closed by aydoor 19 provides ready and-'convenient aeoess to said smudge chamber for replenishing the same with combustible matter. I

'Interposedfland suitably supportedi between the smudge chamber 8 and the curing or smoking chamber 9 for separating the same, while permitting of ready communication therebetween, is agratingor grille 20, which latter .is preferably disposed in the horizontal plane of the main floor 5, and serves andfunctions to intercept any of the suspendedcommodities being treated in the curing chamber, which may accidentally drop from their supports and prevent same from falling. into the-smoldering mass of combustibles 17 as will be obvious and apparent. Centrally and fixedly: securedto the rear walliof the curing chamber- 9, adjacent its upper end and extending perpendicularly therefrom beyondthe. forward wall of said chamber, is .a track 21 rigidly I secured .at its opposite orouterzend to verticallyv disposed support22.

A double door.QGhingedly-mounted upon the forward edges of the, verticalside walls of the curing, chamber 9.serves and functionsthereat, as. a forward wall for the.

I also desire to have it understood that certain features of the invention herein disclosed may be employed in other combinations than these shown and described.

Having thus fully described my invention, what I claim as new and desire to secure by 1.
