Application filed August 4, 1914 Serial No.'855,045.

To all e'e'howt'it'hm i concern:

it knovvn t-l'lait we, WVILLIAM R. Jnnvoiqs, (2) ARNOLD 'Wm'r'rixirnn, citi- Zens of the llnited'tatmtes, residing at Cleve land, in the county of Cu a-hoga and State of @h'io, have invented certain new and useful Improvements in Oil-Stoves, of which the following is a full, clear, ande'X'aet description, reference being had to the accompanying drm'vings.

This invention relates to burners, and more particularly to the hurners 'ofoil heating stoves wherein 'a wick is employed. The inven'tion, more specifically, resides in 'a novel construction of gallery and in certain cooperating features of construction of the gallery, :the wink tubes, and the heating drum which is located above the gallery and the burner; Further and more limited objects of the invention will appear herein after in connection with the detailed description of the parts illustrated in the drawii'rg. p

Referring to the drawing forming part hereof, Figure 1"represents a view, partly in section and partly in el'e' "fit-i011, of an oil heater of the "type known to the trade as smokeless heaters and 2 is a view, partly iusetion and "partly in perspective of the gallery which is employed in connection with said heater.

The heater illustrated herein is of the type wherein Wick tubes project upwardly from the central portion of a reservoir, which is mounted within a stove base or base ring, the stove drum being hinged to the stove base through an extended bottom or cone plate Which is open at the center tO'HClIHlt the upper nd ot the air distributer and "the flame burning froin the top or "the Wick, there being a collar depending from the central openingof this plate and adapted to engagetheftop'fof the gallery, which is preferably mounted ontop of the reservoir and surrounds the outer wv-i'clr tube.

It has been tt'oi'ind desirahleto make the gallery easily removable and to provide with an inwardly projecting trough which is adapted to substantially contact with the outer. ivick tube, whereby any particles fallingin the space "between the outside of the-outer Wick tube and thegallerymay be caught and retained until. such time as it is desired to 'relnovethe gallei" when the particles or other material may be conveniently removed front-he gallery by merely invert ing the same. Among the particles thus liable to 'l' all Within this space and accumulate on top of the reservoir are the carbonized portions of the avid: which are liberated in considerable quantity Whenever the top of the wickis rubbed to even and clean the same. However, it frequently happens that the operator, in replacing gallery having the trough ireferrec'l' to, will invert the gallery, with the result that the inwardly projecting trough will "block "the flow of air through the perforations of the gallery then therebe'neath to the exterior of the flame, resultingin imperiec't combustion, with consequent evolution of smoke and the "possibilities of even more serious consequences. It is a further object"ol this invention to provide a gallery construction which is applicable to a stove of the type referred to, which Will. secure the advan tages referred to and which, should the op erator invert the same, will (obviously to the operator) prevent the stove drum from occupying a proper relation to the parts therebeneath and particularly will prevent the e11gageine1it'( tthe latch members vvhieh fasten the drum until the gallery is placed iuits proper position.

In the drawing forming part hereof, 1 denotes the stove base, the'saiine being shown as a ring having legs 2 and having suitable means, as inwardly projecting segmental flanges 3, for supporting the reservoir 4. Although the reservoir may he supported in any approved manner Within the stove base, We have shown the top of the reservoir as provided with a 'flange 5 which is adapted to be supported by upwardly proj ecting bosses 6 on the segmental flanges 3 a construction described and cl'aimed in our copending application No. August 4, 1914.

The reservoir fisof the type shown in the aforesaid application, being shallow and having an extended substantially horizontal top 7. The reservoir isprovidedwith a cen- 855,044, filed tral opening for the outer wick tube 8 the inner Wick tube These tubes prefer ably extend completely 'tliroug'hfthe reservoir and project above and below the'sa'me,

Projecting upwardly from the top of the inner Wick tube is the air distrihuter 10,

which may be of any approved type, such, for instance, as disclosed in the patent to Wm. B. Jeavons No. 906,887. Above the reservoir is located the drum 11, said drum being secured to a bottom or cone plate 12, the portion of which within the drum is of frusto-conical shape and is provided with a central opening. The portion of the cone plate outside of the drum projects clownthere depends a collar 16. The body of this collar is substantially cylindrical, but is pro vided at its lower end with an outwardly flaring skirt comprising an outwardly projecting portion 17, a downwardly projecting portion 18, and an outwardly and downwardly flaring portion 19. ThlS skirt cooperates with the top of the gallery, will now be described:-

The top of the reservoir, adjacent to the wick tube 8, is formed into a substantially horizontal annulus, indicated at 20, and the metal of the reservoir bounding the outer edge ofthis annulus is preferably inclined outwardly, as shown at 21. The gallery which we employ comprises a substantially cylindrical wall 22, the upper edge whereof is bent outwardly and downwardly to form an inverted U, as shown at 23. The metal forming the bottom portion of the cylindrical wall is bent outwardly and downwardly to provide a flange 241, which may be of the same inclination as the inclined surface 21. A sheet metal annulus is connected to the flange 2 L by having its outer edge portion bent therearound, as shown at 2 1,

thebottom of the outer portion of said annulus contacting with the flange 24:, as shown at 2 1 The annulus extends horizontally inwardly from the bottom of the wall 22, forming a'bottom 25 for the trough ,(tobe described hereinafter) and a means which and the bottom row of perforations in the wall 22.

The parts will be so constructed that the gallery will be practically centered by means of the engagement of the inner edge of the flange 26 with the outer wick tube, and the parts will be so proportioned that, when the drum is swung downwardly upon its hinge and latched to the stove base, the top of the gallery will be in substantial engage ment with the outwardly projecting flange 17 of the collar 16. It will be evident that any matter that may drop within the space between the vertical wall 22 of the gallery and the outer wick tube will be collected within the inwardly projecting trough can ried by and forming part of the gallery. It will also be evident that, when the drum is unlatched and swung back upon its hinge, the gallery may be lifted from its seat, the matter within the trough removed, and the gallery conveniently replaced.

In the event that the operator should invert the gallery, it will be evident that the inwardly projecting trough will then extend above the perforations in the gallery and will block the flow of air through these perforations to the outer portion of the flame, with corresponding detriment to the combustion and the possibility of serious consequences. To prevent the stove from being operated with the gallery thus inverted, the outwardly projecting flange is provided. Through the provision of this flange (which is laterally extended to prevent it from entering the skirt which depends from the collar 16) it will be impossible for the operator to close the drum, the flange engaging the collar and preventing the drum from closing to an extent that will permit the latch member to cooperate. Only by removing the gallery and placing it in proper position can the drum be closed. In other words, as long as it is possible to close the drum, the operator will know that the gallery is in proper position to perform its usual functions and the additional functions due to its peculiar construction and environment; when it is impossible to close the drum, the operator will know that the gallery has been inverted and will have to remove it and restore it to proper position before the stove can be operated.

The depending skirt 18 forms in eflect a telescopic connection with the top of the gallery 22. This accommodates any irregularity that may arise through imperfect assembling of the parts; it also accommodates variations in the positions of the bot tom of the collar and the top of the gallery, due to the expansion and contraction of the cone plate by which the collar is carried. lVhen this plate expands, through the heating operation, the tendency is to elevate the collar. The telescoping connection between ermee be varied or 'cl'epttrted froin esdesirable, butv without fleeting the invention covered hereby; and We do not proposeto be li lnited to such details of con'struetie'n except asthey may be positively included in the elachns hereto annexed or their inclusion may be rendered necessary by the'prio'r state of'the art.
