LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 554,491, dated February 11, 1896. Application filed 0ctober 15, 1894. Serial No. 525,947. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH JAUOH, 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 the 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 a lampburner constructed in accordance with my invention with the gallery in its depressed or normal position; Fig. 2, a view, partly in elevation and partly in vertical section, showing the gallery in its elevated and locked position; Fig. 3, a view in transverse section on the line a b of Fig. 2; Fig. 4, a detailed view showing the connection of the lower ends of the arms of the gallery with the stop-ring; Fig. 5, a detailed view showing one of the arms in its locked position.

My invention relates to an improvement in that class of lamp-burners for central-draft lamps which have vertically-adjustable galleries, adapted to be locked in their elevated positions, in which they permit a taper or match to be applied under the gallery to the wick without the removal of the lamp-chimney, the object being to produce at a low cost for manufacture a simple, useful, and attractive article, composed of few parts, not liable to derangement, and very convenient to operate.

With these ends in View my invention consists in a lamp-burner having certain details of construction and combinations of parts, as will be hereinafter described and pointed out in the claims.

As herein shown, the gallery A is furnished with four corresponding depending arms B, arranged at equal distances from each other, and having their lower ends secured by rivets b to a horizontally-arranged coupling-ring C, which has also the function of a stop.

By reference to Fig. at of the drawings it will be seen that the coupling and stop ring C is provided with four offsets 0, arranged at equal distances apart and corresponding in depth to the thickness of the lower ends of the arms which fit into them, so that the inner faces of the arms will be flush with the inner periphery of the ring. The gallery is also furnished with four spring chimney-holding fingers D, which are formed integral with the upper ends of the arms B, the said fingers being offset at a right angle from the upper ends of the arms to form horizontal bearingshoulders d, upon which the gallery rests, and to which it is secured by rivets d. I do not, however, limit myself to forming the said depending arms and spring-fingers integral with each other, though that construction is compact and effective and presents a Workmanlike appearance. The lower ends of the said arms have bearing and play up and down upon the outer face of a bearing-ring E, which is secured in a vertical position and at a point between its upper and lower ends to the inner edge of a horizontal flange F, extending inward from the upper end of the perforated burner-skirt F, which terminates at its lower end in an integral neck F containing an indented bayonet-groove F which receives a retaining-point,which is not shown, but which projects inward from the collar of the lampfount, which is also not shown. The external diameter of this bearing-ring is enough smaller than the internal diameter of the stopring before mentioned to permit the same to slide freely up and down over its projecting lower end.

Four long narrow slightly-curved slots f, formed in the inner edge of the flange F at equal distances apart, give passage to the lower ends of the arms, as clearly shown in Fig. 3. The said slots are substantially as long as the arms are'wide, so that they guide the arms laterally and prevent the gallery from rotation except as required for locking the same in its elevated position, for which purpose the extreme lower ends of all the arms are cut away to form locking-notches B, which, when they are brought into line with the said slots by the elevation of the gallery to its highest position, permit the same to be rotated to a distance represented by the depth of the notches which are carried over, so to speak, the adjacent end walls of the slots, as shown in Fig. 5, in such a manner as to lock the gallery in its elevated position,

from which it is readily unlocked by rotating it in the opposite direction and clearing the notches from the end walls of the slots.

I have before spoken of the coupling-ring C as having a stop function, and will now mention that when the gallery is lifted to its highest position the said ring rides up over the projecting lower end of the bearing-ring E, and then engages with the lower face of the inner edge of the horizontal flange F, located at the upper end of the burner skirt or body F, whereby the upward movement of the gallery is limited. On the other hand, the downward movement of the gallery is limited in the ordinary manner by its engagement with the flange of the burner-skirt and the upper end of the same.

It will be understood from the foregoing that the gallery is guided in its vertical m ovement without any reference whatever to the outer wick-tube H, between which and the bearing-ring there is a clear space H, as shown in Fig. 3.

As herein shown, the lower end of the outer wick-tube H is furnished with an integral cup-shaped collar H adapted in size to fit within the collar of the fount and constructed with a vertical slot 71 through which the projection on the collar of the fount passes to enter the bayonet-groove F formed in the neck F located at the lower end of the burner body or skirt. It will thus be seen that the outer wick-tube is secured in place not directly but through the medium of the body of the burner, and I would call attention to the fact that inasmuch as the slot h before mentioned is a vertical slot the rotation of the burner in one direction or the other for the purpose of locking it or unlockingit will not disturb the position of the collar 11 located at the lower end of the outer wick-tube.

The coupling of the burner-body and outer wick-tube to the fount of a central draft lamp by means of an inward projection on the collar of the fount is so well known that I have thought it unnecessary to illustrate the fount or describe this point more at length.

I would have it understood that in carrying out my invention I may make some changes from the construction shown and described, and I do not therefore limit myself thereto, but hold myself at liberty to make such alterations as fairly fall within the spirit and scope of my invention. I am aware, however, that it is old to provide the gallery of a lampburner with depending arms and to connect the lower ends of the said arms with a tube adapted in diameter to fit over and ride up and down upon the exterior surface of the outer wick-tube of the burner, and that it is old to notch such arms to adapt them to be utilized for locking the gallery in its elevated position by a slight rotary movement of it.

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

1. I11 a lamp-burner, the combination with a burner-gallery, of arms depending therefrom, a burner-body, a short, vertically-arranged bearing ring permanently secured within the upper end of the said body and terminating above the lower end thereof, a coupling-ring joining the lower ends of the said arms which pass downward into the burner-body and bear upon the outer face of the said bearing-ring, and a removable outer wick-tube of smaller diameter than the said bearing-ring, between which and it there is an annular space, substantially as set forth, and whereby the depending arms of the gallery are supported upon the bearing-rin g and without reference to the outer wick-tube, the removal of which from the lamp-body does not affect the support of the said arms.

2. In a lamp-burner, the combination with a burner-gallery of arms depending therefrom, a burner body or skirt having an inwardly-projectin g horizontal flan ge located at its upper end, a short, vertically-arranged bearing-ring located within the said burnerbody and permanently applied to the inner edge of the said flange, which is constructed with clearance-slots for the downward passage through it of the lower ends of the said arms, which are notched for engagement with it when the gallery is rotated, a coupling-ring secured to the lower ends of the said arms, the inner faces of which bear upon the outer face of the bearing-ring over the lower end of which the coupling-rin g is free to slide up and down, and a removable outer wick-tube of smaller diameter than the said bearing-ring between which and it there is an annular space, substantially as set forth, and whereby the depending arms of the gallery are supported upon the bearing-ring and without reference to the outer wick-tube, the removal of which from the lamp-body does not affect the support of the said arms.

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

JOSEPH JAUCI'I.
