' Be 'it known residing at 83, p p

land, have invented certain Improvements Relating t3 Heatingnstoves or (hens forDr'yingl dus the Other trial"Pur'poses, of whic following is a specification.

This invention relates to heating moves enamelled were in the courses of fofdrymg its manu acture, and also other stoves or ovens for various industrial purposes,. meluding bread and other baking or cooking operatlons.

. The invention comprises the provisionwith a chamber or'container for the articles to be dried, baked, or subjected to heat treatment, simple and reliablemeans for the efficient transfer to the said chamber of the heat contained in the aseous products of combustion from a urnace (adapted for the burning of gaseous fuel in any e ordinary. manner), whereb the articles placed in such chamber are sub ected to the required "heat treatment with economy, cleanliness and convenience. Referring to the accompanying sheet of ex lanatory drawings igure 1 is a plan of a drying or like stove constructed in accordance with this invention.

Figure the stove on the line A. A.. (Fi re 1) whilst Figure 3 is a sectional end'e evation on the line B. B. in'the direction indicated by the arrow (F 1);

The same reference letters, inithe difl'er ent views indicate the same or similar parts.

The chamber a is of. an esuitable construction and providedwi b for the admission and withdrawal of the articles to be subjected togheat treatment therein. Below the":falee.;jhaae or latform as c'of the chamber, there is p the circuitousl arralzlgld or looped iron or other metal pi d; e ends e'a'nd-j of such pipe solid, liquid or 2 is a sectional side, elevation of :doorssuch as the mixin duct'i associated in series with thepipe 7 and forming therewith-the conduit or'connection between the delivleg or et f "outlet side/of the blower g and the of the piped. The communication between the furnace h and the duct 11 is effected by means ofthe'lateral flue k; the pi "i is in lateral communication with the c imney or outlet flue l the said communication being controlled or adjusted by means ere v ve or regulator m. 1 The junction of the said lateral the k with the is greferably' formed, as shown at igure' 2 an 3, by a trough or channel a extend' acromtthe said not, the sectional area d which is enlarged to receive the trough and provide the passages 70, adjacent the trough sides," to.; maintain the communication belower and upper parts of duct 1'. starting up or putting the aforesaidiapparatus into'use, t e valve m is moved into-the position for closing or cutting ofl' communication between the blower an the pipe 7'; v- By the action of the blower which driven b an electric motor or t rough-the belt pu ley p or otherwise) the us products of combustion from the n are then drawn through the flue k andduct i to the inlet f of the circuitous pipe :d,'thence throu h the said pipe (I to the inlet side of the b ower. From the blower thegaseous roducts pass direct to chimne or outlet ue l for discharge.

On the exterior of said wall which in In this manner the temperature in. the

of the duct i ioo chamber a may be varied from that obtain- 106 able from the slowest ible rateof combustion in the furnace up to a rate of combustion giving the highest tem rature the 7 iron or metal ipes and satisfaeto rily with-stan The said 0 amber a may be 110 this example is also the and w building containing the chamber a), there is a a fan or blower g and a ,furnace a h. e outlets of the piped is attached to the suction or inlet side of the said blow- 66 erg. Withthefurnacehtherempmvided fitted with ventilators-as q for the, esca "e of vapour driven ofl 'from the articles p aced therein for drying or heat treatment.

The direction offlow of the hotwgases through the apparatus is indicatedby the arrowsshow'n'inthe drawings:

Having thus describedpur, invention what we claim as new and desire'to secure by Letters Patent is 1. In stoves I or ovens, the combination comprising a chamber, a pipe extending 'circuitously through said chamber and having its inlet andfoutlet ends'onithe exterior of the chamber wall, a blower with inlet connected to the outlet end of said circuitous pipe',.a connection betweenthe outlet of said blower andthe inlet end of 'tlie circuitous v pipe, a chimney, a lateral communication between the said connection and said chimney,

pipe,,a furnace, a ductconnected to the inlet'end of said circuitous pipe, 1: connecting pipe between such duct and the outlet ofsaid blower, a chimney, a lateral communi cation between said connecting pipe and said chi1'nney,' a regulator-for said frommunication, and a flue putting said duct in communication with "said furnace, as set forth. 3. In stoves or ovens, the combination comprising a chamber, a pipe extending circu'itously through said chamber and having vitsinlet and outlet ends on th'e" exterior of the 'chamberwall, a blower with inlet, con

nected to the outlet endof said circuitous pipe, a furnace, a duct-connected to the inlet end of said circuitous ipe, a connecting pipe between saiddufct' and the outlet of said blower, a chimney, a lateral-communication betweensaid connecting pipe and said chimi v ney, a regulator for said communication, a flue from said furnace, and a trough extend ing from said flue across said duct and providing therein centraland side passages, as

set forth. 7 v
