GAS OVEN'.
Application led February 16, 1928, Serial No. 254,726, and in New Zealand March 1, 1927.
This invention relates to gas ovens.
The objects of the inventionl are, firstly 4to provide an improved construction for withdrawing the waste gases therefrom in 5 such a manner that the said gases will be caused to thoroughly transverse the interior before escaping, and, secondly to provide means for pre-heating the air supplied to the burner to support combustion, thereby eiiecting an economy yin gas consumption.
In carrying these objects into effect the present invention consists briefly in the provision, at a point immediately to the inner sine of the front of the oven and ata level beneath the door opening, of one or more outlet-openings arranged to communicate by means of one or more passages extending horizontally, or virtually so., at the bottom of the oven, with a chimney or vent-pipe arranged at the rear, and the provision in conjunction with the portion of the said vent-pipe connecting with the said passage or passages, of ajacket-space arranged to communicate between the at-l niosphere at the exterior of the oven and a point in the interior of the latter adjacent to that at which the burner is located.
The arrangement is such that the heated gases rising from the burner at the back portion ofthe interior of the oven become slightly cooled on reaching the topv thereof and in consequence vpass downward again at the front of the oven and enter the said outlet opening or openings from whence such gases are delivered byV the said hori- Zontal passage or passages to the vent-pipe. This withdrawal of the gases serves to induce an in-flow of air through the said jacket-space to the burner, such incoming air being heated in passingl through the jacket space.
In order that the nature of the invention and its construction may be clearly under stood, it willvnow be fully described and eX- plained with reference to the accompanying drawings, in which Fig. 1is a sectional elevation of a gasoven, illustrating one preferred embodiment of the invention.
Fig. Z-is a plan-view of the same along the line II-IL Fig. 1, and wherein the po' sitions of the outlet openings are indicated in dotted lines,
Fig. 3-is a sectionalelevation along the une 111411, Fig. 1.
Fig. i-is a `plan-view of the front por-V tion of the oven illustrating a slight modiiication of the arrangement shown in the preceding figures and wherein the positions of the door and the outlet 'openings are indicated in dotted lines, l
Fig. 5-is a sectional elevation of the lower portion of the oven,illustrating a further modification.
Fig. 6is a plan-view along thel line VI- VI, Fig. 5, and,
v Fig. 7-i's a sectional elevation of the lower portion of the oven, illustrating a still further modification.
As here shown, 1 represents the oven struc ture, from which the shelves have been omitted, such oven being formed at its front side with the customary door 2 enclosing the door-opening 3 by means of which access is gained to the interior, while located at or near the rear lower' portion of such oven is the gas-burner 4 by means of which such .oven is heated.
In one form of the construction, as here shown in Figs. 1, 2 and 3, there is provided along the inner side of the front of the oven, at a level beneath the door opening 3, a horizontally disposed flue `5, through the upper side of which are formed openings?) by means of which the waste gases from the oven are adapted. to enter such flue. j At its lateral sides the said oven isformed with passages 7L connecting at their forward ends with theends of the flue 5 and extending to the rear of the oven where they connect with a Y-shaped or T-shaped chimney or vent-pippe 8, the latter being preferably fitted with a regulating valve, as 9, turnable as by means of a crank or handle l0 for the purpose of varying the opening area of the ventpipe and so governing the escape of the gases from the oven.
Two slides 11 may be provided, one in each of the passages 7 for the purpose of controlling the flow of the gases therethrough such slides being operable from the front or sides of the oven.
In a slight modiiication of this construction, as shown in Fig. 4, the said flue in-l stead of extending across beneath the door opening, -is divided to constitute a pair of ypockets 12 arranged one in each of the fr'ont corners of the oven'. The said pockets 12 Cil will. each be formed with one or more entrance openings 13 for admission of the waste gases which are then conveyed by the lateral passages 7 to the vent-pipe 8 as in the vpreviously described form.
In a further modification of the construction, as shown in Figs. 5 and 6,.in lieu of the flue 5 or pockets 12, there is provided at the inner side of the front of the oven be-v neath the door-opening 3, a funnel-shaped intake member 14 having an upwardly facing mouth from whence such member diminishes in area to its lower end.
The said intake member 14 is preferably oblong or of other similar elongated form inV plan and arranged with its longer sides parallel with the front of the oven in order that it may occupy as littlev space as possible in the interior of the oven.
Connecting with the said lower or smaller end of the said intake-member 14 is a horizontal, or 'substantially horizontal passage 15 which extends centrally across the bottom of the oven to pass beneath the burner 4 and connects with a vent-pipe 16 at the rear.
The bottom of the oven is enclosed by means of a horizontal plate 17 preferably arranged at a level corresponding approximately with that of the burner 4, the rear portion of such plate being preferably curved or swept downward sufliciently to pass beneath such burner.
The said plate will preferably be enamelled and arranged to rest upon ianges or projections, 18, to permit of such plate being removed for cleaning purposes,
In a further modification of the construction, as shown in Fig. 7 the outletfopenings, as 19 will be formed through the plate 17 and at an interval beneath which a second horizontal plate20 will be provided to it closely with the walls of the oven and thus constitute a chamber or passage 21 through which the waste gases entering through the openings 19 will be conveyed to a vent-pipe as 22.
As already mentioned there is provided in conjunction with the portion of the ventpipe connecting with the said horizontal communicating with the atmosphere as at 24 and connecting as by means of an opening 25 with the interior of the oven at a point adjacent to the burner 4, the arrangement being such that air entering such shownv in Figs. 1,2 and rby providing av wall as 26 spaced at an interval from the vent-pipe or as shown in Figs. 5, 6, and 7 by providing walls as 27 to connect between the vent-pipe and the wall of the oven.
In operation the Yheated gases rising from the burner 4 at the back portionof the interior of the oven will become slightly cooled on reaching the top and will in consequence pass downward again at the front portion of such oven and'enter the said outlet openings from whence such gases will be conveyed by means of the horizontal passage or passages to the vent-pipe, such withdrawal of the gases serving to induce an iniow of air through the jacket-space, where it Vbecomes heated by the vent-pipe, to the portion ofthe interior of the oven in which the burner is situated.
I claim:
1. In a gasoven having a door opening at the front and a gas-burner disposed in the rear lower corner of such oven, outlet-openings for waste gases arranged immediately to the inner side of the front of the oven at a level beneath said door-opening, and substantially horizontal passages at the bottom of the oven communicating with said outlet openings and with a vent-pipe at the rear of the oven. y
2. A gas-oven as defined in claim 1 a jacket-space being provided in conjunction with the portion of said vent-pipe connecting with said horizontal passage or passages, said jacket-space communicating between the atmosphere at the exterior of the oven and the portion of the interior of the latter adjacent to the burner to pre-heat the air supplied to support combustion.
3. Agas-oven as defined in claim'l, the
lowcr'end of said oven being enclosed by a plate removably supported, said plate beingv arranged approximately at the levelof the burner and having its rear portion curved downward to lie ,lower than 'the openings of said burner.
In testimony whereof I have hereunto affixed my signature.
FREDERICK SAMUEL SCOTT.
