WiCK-RAISING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 404,274, dated May 28, 1889.

Application filed June 19, 1888.

To all whom it may concern:

Be it known that I, PATRICK J. GLYNN, of Highland, in the county of Ulster and State of New York, have invented a new and Improved l/Vick-Raising Attachment, of which the following is a full, clear, and exact description.

This invention relates to lamps provided with a wick-raising gear mechanism, whereby the wick may be raised and lowered without removing the fount, and has for its object to provide an improved device of the character referred to so arranged that the burner may be readily taken off and put on, and the wick raising gear mechanism properly adjusted so that it always may be effectively operated.

The invention consists in a lamp provided with a wickraising mechanism constructed and arranged as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figurel isan elevation of alamp constructed in accordance with this invention. Fig. 2 is a view of the neck of the lamp with burner detached. Fig. 3 is a view of the neck of the lamp in portions before it is completed, parts being broken out to better disclose the construction; and Fig. 4 is a detail of the wickraising mechanism.

Heretofore in lamps with a wick -raising mechanism in which the shaft for raising and lowering the wick was geared with a vertical shaft it has been found that a perfect adj ustment of the gearing could not be effected, owing to the fact that the burner could not be screwed down tight and at the same time bring the bevel gear-wheel of the wick-shaft into proper mesh with the bevel gear-wheel of the vertical operating-shaft, since the screw of the burner cannot be so determined as to bring the gear into the proper engagement when the burner has been screwed down tight, and also because as the screw becomes worn the bevel-wheel of the wick-shaft will be carried too low to properly engage the bevelwheel of the vertical shaft when the burneris in place.

A lamp with a spring-catch to hold the Serial No. 277,610. (No model.)

bevel gear-wheel of the wick-shaft in engagement with the bevel gear-wheel of the operating-shaft has been provided, as shown in Letters Patent No. 309,481, granted to McLeod December 16, 1884.

This invention is also intended to obviate the defect heretofore mentioned and provide an improved lamp having a ,wickraising mechanism which will be effective.

0 indicates the fount or oil-receptacle of a lamp constructed with the ordinary form of base P, having a catch and spring, H, for attachingthe' lamp to the globe-frame.

The neck of the lamp is formed by means of an internally-screw-threaded collar, E, permanently held and adapted to turn freely upon a flanged ring, L, projecting into and soldered to the rim L, surrounding the opening of the fount O, the flange L of the ring L engaging an internal annular shoulder of the collar E,-and the collar resting on the rim L. The collar E is formed with a milled flange, E, for turning it.

The internally-threaded portion K of the collar E extends from the top of the collar to the flange E, where the upper edge of the ring L forms a seat for the screw D of the burner D, the screw D equaling inlength the screw-threaded portion K of the collar E, so that when the burner is drawn down tight in the collar E the rim D of the burner will rest against the threaded portion K of the collar E.

The wick-raising mechanism is constructed as follows: In a sleeve or tube, G, secured in a bracket, F, projecting from the side of the fount O, and fastened at its lower end to the base P, is mounted a shaft, G, the lower end of which projects through the base P and is provided with a thumb-nut, I. The upper end of the shaft carries a bevel gear-wheel, B adapted to mesh with a bevel gear-wheel, B, on the wick-shaft A, having the usual spurpinions, O, for raising and lowering a wick. Upon the upper end of the tube G is secured, by solder or otherwise, an arnnS, having a notch or recess, S, in its upper end for the wick-shaft A to rest and turn in when the burner has been drawn down into engagement with the neck of the lamp and the gearwheels B and B brought into engagement with each other. Vhilel have described the shaft G as preferably mounted in the tube G, it is obvious that the shaft G may be mounted on the fount in any other suitable manner.

In use, after the fount has been filled, the end of the screw D is engaged with the internally-screw-threaded portion K of the collar E, the shaft A being located above the notch S in the arm S. The burner D is then lowered into engagement with the neck of the lamp by turningthe collarE, which causes the screwD of the burner D to be drawn down into the threaded portion K until the lower end of the screw D bears against the seat formed by the upper end of the ring L and the rim D of the burner is seated on the portion K of collar E. The wick-shaft A is also brought down, so as to rest in the notch S in arm S, the bevel gear-wheel B meshing with bevel gear-wheel B and the arm S keeping the bevel gear-wheel B in en gagement with gear-wheel B.

To take off the burner, it is simply necessary to turn the collar E in the opposite direction from that in drawing down the burner D, when the screw D and the collar E will be disengaged.

By means of a lamp constructed and arranged as herein set forth the wick of a railroad or other lamp or lantern may be effectively raised or lowered without removing the lamp, and the burner readily removed and replaced, as required,the bevel-gearin g being always brought into proper engagement.

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

1. The combination, with a lamp-fount provided with a vertical shaft carrying a bevelgear and a burner provided with the usual threaded portion, and a wick-shaft provided with a bevel-gear, of an internally-threaded collar revolubly held to the fount, substantially as shown and described.

2. The combination, with the fount O, having the flanged ring L, with flange L ,permanently secured in the neck-openin g of the fount, of the rotary collar E, having an internal shoulder engaging the flange L substantially as shown and described,

3. The combination, with the fount O, the threaded collar E, revolubly held to the fount, the shaft G, and pinion B, of the burner D, the shaft A, and pinion B, substantially as shown and described.

4. The combination, with a lamp having its neck formed with an internally-screwthreaded revoluble collar, a burner having a screw-threaded portion adapted to engage the screw-threaded collar, and a horizontal wickshaft provided with a bevel gear-wheel, of a vertical operatingshaft mounted on the lamp and having a bevel gear-wheel adapted to mesh with the bevel gear-wheel on the horizontal wick-shaft, substantially as shown and described;

5. The combination, with a lamp having its neck formed with an internally-screwthreaded revoluble collar, a burner having a screw-threaded portion engaging the screwthreaded collar and seated on the neck of the lamp, and a horizontal wick-shaft provided with abevel gear-Wheel, of a vertical operatingshaft mounted on the lamp and having abevel gear-wheel meshing with the gear-whecl on the wick-shaft, and an arm mounted on the lamp and having a notched end in which the wick-shaft rests, substantially as shown and described.

6. Alamp consisting of the fount O, with the rcvoluble ring 13, revolubly attached thereto at the opening of the fount and having the internally screw threaded portion K, the burner D, having the screw D, cngagingthe screw-threaded portion K of the ring E, the horizontal wick-shaft A, provided with the bevel gear-wheel B, the tube G, mounted on the fount O and having an arm, S, with notch S in its end, in which rests the wick-shaft A, the Vertical shaft G',journaled in the tube G, and the bevel gear-wheel B on the upper end of the shaft G, meshing with the gear-wheel B on the shaft A, substantially as shown and described.

PATT .T. GLYNN.
