I heat is required, and has for its objects to provide such a device adapted to be'he'atedby fluid circulation around the walls there" UNITED STATES PA E OFFICE.
JOHN R. MQK OWN', or TORONTO, ONTARIO, CANADA. I
HEAT-BOX.
Dominion of Canada, have inventedcertain new and useful Improvements'in Heat- Boxes, and do hereby declare th'at the following is a full, clear, and exact descrip tion of same.
This invention relates to heat boxes or chambers particularly adaptable tobe used as incubators, or for the purpose of raising bread and such purposes where a steady of, and to provide simple and efficient means for carrying such an ob ect into effect.
Further ob ect-s subs diary to or resulting from the before-mentioned main objects or" from the constructlon of the inventlon as'it may be carried into effect, will become apparent as the invention is hereinafter further disclosed.
As a means of carrying the said invention into effect, I may provlde a heat chamber with double lateral walls, between which fluid in a heated state may circulate, a suitable heater being connected to the chamber or chambers formed between the said double wall, the said chamber being suitably insulated to prevent the escape of heat outwardly from the fluid therewithin, whereby all, or practically all, of such heat will be directed into the heat box as required; and it is preferred to divide the fluid chamber into upper and lower passages by means of a wall extending across the same intermediate of the height thereof, the said wall terminating at a desirable distance from the extremities of the said chamber, whereby the passage of heated fluid from the upper side to the underside of the said wall will be permitted, all of which is more particularly described and ascertained in and by the following statement having reference to the example illustrated in the accompanying drawing, in which:
Figure 1 is a broken perspective view of a heat box constructed in accordance with this invention:
Fig. 2 is a sectional plan view of the same, and
Fig. 3 is a vertical section of the rear end of the same showing the heater connection thereto,
- spectively, by a transverse Specification of Lettersl atent. I Patented Oct, 28, 1919, "A lication filed January 26, 1918. S eria1No.213,998. 1
Similar characters of reference indicate simllar curved at the rear of the box, whereby 1n plan it may be said to be U-shaped, a'door 2 extending between the extremities of the said lateral wall A and serving, when closed,
with the top' 3'and bottom l of the heat box" to form an inclosed receptacleforany article which it may be desired to subjectt'o a continuous heat, 5,15 vbeing slides upon which, for example, an incubator tray may be accommodated. '6 is a further wall parallel to the aforesaid wall 1*, and forming anjinclosed chamber therebetween, and 7 *isastilI-further and outer wall extending around the said wall 6 and inclosing a layer of heat insulating material 8,"such"as asbeswe: The chamber between the walls 1 and 7, which walls will be hereinafter referred to in combination as a double wall, is preferably divided into upper and lower pas sages, which are indicated as 9 and 9" reartition 10, terminating at a desirable dlstance from the forward extremities of the said double wall, whereby communication is established between the said upper and lower passages 9 and 9". 11 is an inlet to the said chamber,
through which fluid, preferably preheated, i
may be introduced to the said chamber, and 12 is a heater having conduits 13 and 14: connecting the same with the upper and lower passages 9 and 9 respectively in the said double wall, whereby a convection current may be secured, as will be readily understood. 'With a device of this type, heat within the box may be readily secured by the pouring of preheated fluid into the chamber between the walls 1 and 6, such heat being thereafter maintained by means of the heater 12, and any well-known means may be employed to effect the regulation of theheater; and it will be understood that changes in the exterior temperature will not easily affect the temperature within the said heat box, owing to the heat being secured from the walls thereof, through which, in the old types of heat boxes, the heat more or less escaped, and furthermore, in the device now proposed, it will be comparatively easy to retain a steady temperature owing to the limitations of temperature to which fluids may be raised in the surrounding walls, even though the temperature of the heating medium may become excessive.
This invention may be developed within the scope of the fOllOWiIlg claims without departing from the essential features of the said invention, and it is desired that the specification and drawing be read as being merely illustrative and not in a limiting sense except as necessitated by the prior art.
What I claim is 1. A heating device of the character described comprising a box like body having a top, a bottom, a door and a side wall, said side wall being U-shaped in plan and doubled to form a U-shaped hot water receiving chamber, a horizontal partition dividing said chamber into upper and lower compartments and terminating short of the ends of the side wall to allow communication between the compartments, a filling inlet cornmunicating with the medial portion from one of said compartments, pipes leading from the medial portions of both of said compartments and a heating chamber with which said pipes communicate.
2. A heating device of the character described includmg a box like body comprising a bottom, a top, a side wall U-shaped in plan having its upper and lower edges joined with the top and bottom, a door for the body, another side wall surrounding and spaced from the outer face of the first mentioned side wall and secured to the upper and lower edges thereof to provide a hot water receiving chamber an outer side wall surrounding the last mentioned side wall, a layer of heat insulated material between the last mentioned side walls, a horizontal partition arranged in the chamber and terminating short of the ends of the side walls to provide upper and lower communicating compartments, a filling inlet extending through the medial portions of the outer side wall and colmnunicating with one of the compartments, pipes leading from the medial portions of the compartments and a heating chamber associated with the outer ends of the pipes.
