LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 554,038, dated February 4, 1896.

Application filed November 20, 1 8 9 3.

To all whom it may concern.-

Be it known that I, JOSEPH C. SHULL, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Lamp-Burners; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a view in side elevation of one form which a lamp-burner constructed in accordance with my invention may assume, the gallery being shown in its depressed position; Fig. 2, a corresponding view with the gallery shown in its elevated or lighting position; Fig. 3, a detached view of the gallery with a portion of it in vertical section; Fig. 4, a view of the gallery in transverse section on the line 00 0c of Fig. 3 and looking toward its upper portion; Fig. 5, a plan view of the burner with the gallery removed; Fig. 6, a View in vertical section through one side of the burner, showing the gallery in its vertical position and one of the springs in engagement with the upper edge of the outer wick-tube.

My invention relates to an improvement in that class of lamp-burners in which the gallery is adapted to be raised and lowered for lighting the lamp without removing the chimney.

\Vith these ends in view my invention consists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claim.

In carrying out my invention as herein shown I provide the gallery A of the burner with a depending sleeve B, adapted in its dimensions to fit over the outer wick-tube C of the burner and to slide up and down freely thereupon and corresponding in size to the central opening of the gallery, into which its upper end is directly connected, as shown in Fig. 6. The said sleeve B is constructed with openings B, which are located slightly below its upper end and which permit a match or other lighted taper to be applied to the wick over the upper edge of the outer wick-tube C when the gallery is raised, the said openings Serial No. 491,454. (No model.)

being arranged so that when the gallery is depressed the said wick-tube closes them and cuts off any draft through them to the flame. For sustaining the gallery in its elevated po- 5 5 sition I provide the said sleeve with springs D, arranged with their free ends downward. These springs are formed integral with the sleeve in the vertical portions B thereof lying between the openings B. As shown, the sleeve has four of such openings, and hence four vertical portions; but only two of the latter are constructed with springs. If desired, however, all of the said vertical portions may be provided with springs. The lower end of each spring is constructed with a beveled retaining-shoulder cl, and each spring is bent or set so that it will exert a constant efiort to spring inward Within the line of the sleeve and within the line of the outer wick-tube C. Then, therefore, the gallery is raised so that the lower ends of the springs are elevated above the upper edge of the wick-tube, the springs will at once spring inward over the upper edge of the same, as shown in Fig. 4 of the drawings, and thus support the gallery in its elevated position. Owing, however, to the beveled form of their retaining-shoulders, they are easily dislodged from the upper edge of the wick-tube and caused to spring outward and ride upon the outer face thereof when the gallery is forced downward into its depressed or normal posi tion.

By preference, also, I provide against the accidental removal of the gallery from the wick-tube. As herein shown, I accomplish that end by forming in the depending sleeve B of the gallery, in one of the vertical port-ions B thereof, athree-armed flute, the respective portions of which are arranged at a right angle to each other and co-operate with a projection C, formed in the outer wick-tube C. The said flute comprises two vertical clearance portions E E, and a horizontal stop portion E interposed between them. When the gallery is applied to the outer wick-tube, the portion E of the flute is aligned with the projection C, whereby the sleeve is permitted to slip down over the tube until the projection engages with the upper wall of the outer end of the stop portion E of the flute. The gallery is then rotated until the inner end of the said stop portion of the flute, and hence the vertical portion E thereof, has been brought into alignment with the said projection, thus permitting the gallery to be depressed into its normal position. In the ordinary elevation and depression of the gallery the portion E of the flute clears the proj ection C and permits the gallery to be raised and lowered, but it is prevented from being removed from the tube by the engagement of the projection with the lower wall of the inner end of the stop portion of the flute; but the gallery may be rotated somewhat during its elevation or depression. It is not, however, likely that in any ordinary use of the burner the gallery, and hence its depending sleeve, will be rotated enough so but what the lower wall of the stop portion of the flute will somewhere engage with the projection and prevent the removal of the gallery. It is also a simple matter to rotate the gallery to bring the short vertical portion E of the flute into line with the projection, after which the gallery may readily be removed. I have shown only one flute and projection, and that is sufficient for practical purposes; but two may be employed, if preferred. Nor do I limit myself to the use of a flute and projection for coupling the sleeve of the gallery with the outer wick-tube of the burner, for some other means might be used in their place.

The outer wick-tube is combined with a collar F and perforated skirt G, both of ordinary construction and requiring no detail description. The gallery is also furnished with the usual spring-fingers A for clasping the chimney.

I would therefore have it understood that I do not limit myself to the exact construc- .tion herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention. ever, that it is old to construct a lam p-burner with a gallery adapted to be vertically moved for convenient access to the wick, and to connect friction-sprin gs with the said gallery and arrange them to ride upon the wicktube so as to support the gallery in its elevated position. I do not therefore claim such a construction broadly.

I-Iavin g fully described my invention, what I claim as new and desire to secure by Letters Patent, is-

In a lamp-burner, the combination with the gallery and the outer wick-tube thereof, of a depending sleeve corresponding in size to the central opening of the gallery, extended at its upper end directly thereinto and connected therewith, adapted to fit over the outer wicktube, and to slide freely up and down thereupon, constructed below its upper end with lightingopenings which are closed by the outer wick-tube when the gallery is depressed, and also constructed with one or more integral vertical springs arranged with their free ends downward, struck out from those portions of the sleeve lying between the said lighting-openings, set to spring inward to engage with the outer face of the outer wicktube upon which they ride up and down, and having their lower ends bent to spring inward over the upper edge of thesaid outer wiclv tube forsupporting the galleryin its elevated position, and to be sprung outward by the said tube when the gallery is depressed, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
