LAM P-WICK LIFTER.

srncrrrcnrron forming part of Letters Patent No. 402,945, dated May 7, 1889.

Application filed November 21, 1888. Serial No. 291,515. (No model.)

To all whom it may concern.-

Be it known that I, LYMAN T. LAWTON, of Meriden, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Lamp-WVick Lifters, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a side view of a lamp equipped with my improved wick-lifter. Fig. 2 is an enlarged perspective view of the wick-tube and improved attachment, and Fig. 3 detached detail views of the essential features of the invention.

The object of my invention is to provide the wick-tube of an Argand burner with a lifting device so arranged that the tube can be readily attached or detached, and which will be positive in its action, and cannot work loose or become displaced while in use,'as will now be set forth in detail.

In the accompanying drawings, A represents the movable tube, and B the inner stationary tube, between which the wick C is held. In practice the wick 0 moves with the wicktube A, and in order to effect this the inside of this tube has spurs to hold the wick; but as I that forms no part of the present invention I have not shown the details thereof.

Near the lower end of the Wick-tube A is a stud, D, having a suitable head, and in the same horizontal plane and removed a short distance therefrom is a stud or catch, E. The lifting bar or stem F passes vertically through into the lamp-reservoir by the side of the opening, and its lower end is bent into aloop which passes around the neck of the reservoir. To the inner upturned end, G, of the lifter is attached a yoke, II, having therein a longitudinal slot, I, which terminates at the outer end of the yoke in a circular aperture, J. This circular aperture is made of the proper size to receive the stud D on the Wicktube, and the slot I is of sufficient width to receive the body of the stud D,

It will be observed by reference to Fig. 2 that the stud D on the wick-tube has been placed in the yoke and turned so that the stud E rests in the circular opening J of the yoke. In this position the stud E locks the tube A and prevents it from turning. The yoke H is bent so as to conform to the arc of the tube A, and the lifting-stem F is held in its place so as to prevent turning by means of the stud D and yoke H, thereby obviating any liability of displacing or disengaging the yoke from the studs, unless the outer end of the yoke is drawn out so as to clear the stud, when the wick-tube can be turned sufliciently to release the yoke from the headed stud D.

What I claim as new is A lamp having a headed stud and a catch on the wick-tube, in combination with a lifting-stem, on the inner upturned end of which is a horizontally-disposed slotted spring-yoke, substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand, this 19th day of November, 1888, in the presence of witnesses.

LYMAN T. LAWTON.
