STOVE CONSTRUCTION Filed July 1, 1929 Patented Apr. 7, 1931 CLAUDE M. DIBBLE, OF JOLIET, ILLINOIS, AS SIGNOR TO MOORE BROTHERS COMPANY 7 OF JOLIET, ILLINOIS, A CORPORATION OF ILLINOIS PATENT OFFICE STOVE CONSTRUCTION Application, filed July 1, 1929. Serial No. 875,297.

of the door movements and also to the influence of'the cooler outside air whenever the door is opened. The disadvantages 'of each of these conditions are, of coursefreadily apparent. The thermometers have been thus located because of the presence of heating spaces about the sides of the ovens and because the front walls of the ovens usually consist entirely orisubstantially entirely of the oven doors. The mounting and location of the oven thermometers, prior to this invention, have therefore been confined to the front walls, which usually meant the oven 'doors.

'Broadly, the objects of the present invention are to so locate an oven thermometer thatit will be permanently fixed in position and will be protected against the shocks and jars of door movements and against the influenceof outside atmosphere. 7

A more specific object of this invention is the location of a thermometer through a side flue or heating space of an oven without subjecting it to the temperature influence of the flue or oven heating gases passing through such space.

Another object of the invention is the location ofan oventhermometer through a side flue or heating space of an oven and at the same side of the stove as a water heating tank or reservoir positioned adjacent the flue space without subjecting the thermometer to the temperature influence of the reservoir, "and by so mounting the thermometer to protect it against accidental mechanical injury.

Numerous other objects and advantages of the invention will be apparent as'it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings Figure-1 is a partial elevation of a stove embodying the invention;

Fig. 2 is an enlarged partial vertical section taken transversely of the stove and through the temperature indicating device, the latter being shown in full lines, and

Fig. 3 is an enlarged section taken substantially on the line 33 of Fig. 1.

For the purpose of illustrating the invention, the drawings show a coal stove 11 supported on legs 12. A suitable combustion unit or source of heat 13 is providedto heat the stove 11 and a usual oven 14 of the stove.

VVhile the drawings show a coal range, it

will be understood that the invention may be embodied in various types of stoves and ovens, the sources of heat of which may be provided from a usual or preferred construe tion such, or example, as that illustrated at 13 in Fig. 1.

The products of combustion from the source of heat 13 pass up and across the top of the oven 14 and down into a flue or oven heating space 15 which is provided-between the outer right side wall 16 of the stove and an adjacent wall 17 of the oven 14. I This flue space 15 is closed at its front by a front wall 18 of the stove, this wall 18 providing a usual oven opening closed by a suitable oven door 19.- It will be observed that the front wall of the oven itself consists entirely, or substantially entirely, of the oven door 19. The Wall 18 has a marginal flange 21' which extends from the outer right corner of the stove toward the back, as shown in Fig. 3, co-operating with an inwardly disposed, marginal olfset portion 22 of the right stove wall 16 and suitably secured thereto to provide a corner closure for thefiue space 15.

A pocket, generally indicated by the ref erence character 23, is set off in the flue space 15 at the front of the stove by partition walls or

members

24, 25 and 26 formed integrally with the wall 17 of the oven 14. The walls 24 and 25 extend outwardly from the oven wall 17 and are arranged horizontally in spaced relation so that the wall is above the wall 24, as shown in Fig. 2. These walls 24 and 25 are connected along their rear edges by the vertical wall 26 which extends outwardly from the oven wall 17. The

partition walls

24, 25 and 26 cooperate with the side wall 16 and the front wall 18 to form the pocket 23 and to seal it from the flue space 15, leaving the pocket open at its side adjacent the oven 14 and in communication with the oven.

A tube or thermometer shank 27 is arranged through an opening 28 in the side stove wall 16 and extends into the pocket 23. A collar 29 having a flange 31 is provided to embrace a portion of the shank 27 for mounting the shank in the pocket 23 by suitable bolt and nut assemblies 32, which secure the flange 31 of the collar 29 to the inner face o f the stove wall. 16. The collar 29 and the flange 31 hold the shank 27 in place and the flange seals the opening 28. The thermometer shank 27, disposed in the pocket 23, is provided at its inner end with a plurality of perforations or openings 33 to permit the atmosphere of the oven 14 to reach a suitable heat sensitive member (not shown) of the thermometer which actuates an indicating member 34 of the thermometer positioned at the outer end of the shank 27, outside of the oven 14, and a water heating tank or reservoir 35 is or may be mounted at the same side of the stove, as shown in Fig. 3. The indicating member 34 is provided with a suitable scale 34' for indicating the temperature of the oven.

The reservoir 35 is provided with a wall 36 which is positioned adjacent the wall 16 of the stove and a front wall 39 extending out wardly longitudinally of the stove behind the indicating member providing a space 38 between the wall 39 at the reservoir 35 and the indicating member 34 of the thermometer, the space 38 supplementally insulating the indicating mechanism from the temperature influences of the reservoir A check or front finish plate 42 is suitably secured near the front of the stove and extends outwardly therefrom in front of the reservoir 35, as shown in Fig. 3, to form a space 37 between the front wall 39 of the reservoir to the rear of the indicating member 35 and the cheek plate 42 in front of the indicating member.

The cheek plate 42 is made to provide a sight aperture or recess 43 near its edge adjacent the side of the stove, the aperture or recess registering with the scale 34 of the thermometer to readily permit observation of the temperature of the oven. indicated thereby. The recess 43 is cast in the plate 42 to provide a finishing head 44 around its edges, as shown in Figs. 2 and 3.

By thus mounting the thermometer, all of the advantages of the location through the door are preserved and the disadvantages are eliminated. A stationary mounting is thus provided through a side flue or oven heating space and at the same side of the stove as a water heating tank or reservoir, the thermometer extending into the side flue space of the oven and being readily observable. Such a stationary mounting eliminates the misadjustments of the thermometer which are caused by thejars and shocks of door movement, and eliminates the inaccuracies of the thermometer which are caused by exposing it to the influences of the cooler temperatures outside of the oven when the door is open. The thermometer, being located in the space 37 between the plate 42 and the end 39 of the reservoir, is protected against accidental mechanical injury and while the thermometer extends into the flue space 15, it is protected from the influences of the reservoir and the flue space.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
