ATTORNEY QEdB m l i l I I I I I 1 I l WITNESS ran srarns PATENT orr on,


- a, To all whomz'tmay o1ic em,-f i

Be it known that I, EDWARD FLANAGAN, a citizen of the United: States,; residing at 1430 Blavis street, Philadelphia, in the county of Philadelphia and Stateof- -Pennsylvania, have invented new and useful Im-. provements in Smoke-House's, of which the following is a specification. 1 p a V i This invention relatesto smoke -house s, and has for-an object, amongothers to pro vide a novela'nd improved'form ofsmoke genera ting apparatus, which embracesauto matic. features of control and operation, tending to produce a'more'eilicient andmore economically operating means for,,maintaining the temperature ofthe smoke house withinprescribedflimits. I

Another object residesyin the I provision of the smoke house wh-iolreconomizes fuel when inoperation and serves to insurefa positive circulation; of smoke throughout every part thereof, -withou't}t resorting .to the 'use of circulating-fans and simllar zipper} tainances.

I A furtherv obj ectfresidesj in a smoke house havingalsmokejgenerating apparatus posi tioned therein, and an oscillating damperfor controlling the circulation of smoke through the closure, a chain being connected with said damper to retain the same in an open position J111d Wll3ll the smoke outlet door or damper. of saidapparatus, a fusiblev linkqis provided in the chain so that when the temperature within the smoke house reaches a. predetermined j limit, ,said link 1 will fuse so as to. destroy the chain con? nection existing between the dampers, in order that the [latter may revolve to closed positions, whereby. the temperature of A buildingv will be. instantly lowered. The invention consists of novel features,

' details of construction andg'i'combination of parts, which hereinafter will be more parsMoKE-H USE.

' Patented July 2, 1918.

Similar characters of reference denote corresponding parts throughout the several views of the drawing; f

,Referring more particularly to the drawing, the preferred formpf the invention consistsoffais'inoke generator 1, which is positioned interiorly of a smoke house 2,

jthe latter may beof any appropriate size, or constructed from any suitable material,

and is preferablyheated through the agency ofsteam-heated coils 3 or their equivalent,- whereby thetemperatureof the house may be maintained at a required degree necessary improperly conserve'iedible materials positioned therein. Y, r The generator, 1 in its preferred embodiment consists of a,:sheet metal structure which is intern'ally divided, by means'of a mu. or partition 4, tofdefine afuel-receiving hopperga andacombustion chamber '6;

Aecess is to be had to the hopper through ui'ei g acyer a hingedcover 7,' whereby .sua bleruei, such as saw dust. obtained ,jfro'm' certain' woods, may bereadi'ly posi- I tioned therein, 'lhe lower wall of thejhop y per'y5 i preferably inclined toward the iower pemon o'fth'e combustion chamber .6, i

so {fuel positioned within the hopper will lautoma'tically, gravitate toward; said needed. p Air is supplied to the chamber, 6 through combustion cl amber 'as itf consumed for theuse of a substantially funnel-shaped pipe ,8, which communicates with the eX-- terior, of thesmoke house and terminates ing teriorlywithhrthe combustion chamber in a ;-dow'nwardl-y extending nozzle19; pipeis a'dapted to supply afsuificient iq'uan y @O fr hair to the .generatorto conform with,theicombustion requirements .of the latter,ffand"practice hasprovenithe fact that b f'v tue of-this construction it isfnot necessary to'employ a fan' or' blower, suchjas A -l 1.11 thegc n r ti o er d y m fo1j mer Patent #l,133,118. Smoke escapes from" the combustion chamber through a 'damper covered outlet 10 provided in the upper extremity of the chamber 6,, and is: then adapted to circulate throughethe smoke. house so as tobe utilized in curing suitable foods; A cupola 11' is provided'on *the upper portion of the smoke house-and is formed with a smoke outlet opening 12,

and by reasonofthis construction it will be 7 seen that "air will be "permitted to circulate through the smoke house in 'a' constant and steady stream, when the damper 13, is in an open position. v

The smoke outlet of the generator "l'is adapted tobe covered by means of a door or damper ltwvhich, when the generator is in service, is in anopen position, clearly indicated in Fig. 1, so that smoke produced cl'iain. A fusible link'17 is employed to con-' nect the chain 15 with the damper 13 and it will be seen that in the event of thetem per'a'ture of the smoke house'reaching an ab- Inormal or dangerous point the link .17 will fuse sothat theconnection existing between said damper18 and the chain-will bebr'oken. This action will permit the damper 13 to revolve to a closediposition, "shutting-oil'- the thisconstruction"itvvillbe possible to ecocirculation through the Smokehouse, and at the same time will 'release the "damper 14L so as to cover thecombustion'chamber 6; By

nomically cure food stuffs positioned within the' sinokehouse, as the proper temperature required for "properly curing suchm'atter is always "maintained, and excessive waste-producing temperatures are 'a'cc ording ly eliminated. 'VVhen'the' damper 14: revolves'to closed position, the supply of fuel from the hopper5 'to'the combustion chamber'is also automatically cut on; as said damper isc'onnected bymeans of alink 18 with a pivoted door'fl19', associated with the'wa'll 1 4L and designeu to control-the passage ofthe fuel into said combustion chamber; s will be clearly understood. The link'IS also serves to "open the do'o'r 19 when thedamper leg is elevated to permit 'o'fthe rise of'smoke within'the I G' -Q I 1. i From thej"'foregoing des'oripti'on it "is thought thatth'e operation and construction of thepresent invention will be clearlypbvi'o'us to those versed in the art, and there i,271,3oo
