WlCK-RAISER.

SPECIFICATION forming part of Letters Patent No. 407,970, dated July 30, 18 89.

Serial No. 280,570- (No model.)

To all whom it may concern.-

Be it known that I, HENRY E. SHAFFER, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in ick-Raisers; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the drawings acco1npanying this application. 7

My improvement relates to that class of wick-raisers in which the circular wick is attached to a tubular holder that slides up and down 011 the central draft-tube of the lamp, and a handle is attached to the holder that extends up through the top of the lamp and is operated by the fingers.

The invention consists in the construction and arrangement of parts, hereinafter more fully described and definitely claimed.

In the drawings, Figure 1 is a central vertical section of a center-draft lamp, showing my improved wick-raiser applied thereto. Fig. 2 is an enlarged side elevation of the tubular holder and the lower connecting end of the handle. Fig. 3 is an elevation looking at right angles to Fig. 2. Fig. 4 is an elevation of the connecting end of the handle. Fig. 5 is an elevation of the holder and connecting parts, showing a modification in the means for raising the same. i

A indicates a lamp, and B the central drafttube, over which rests the circular wick C, which slides up and down on the draft-tube in the usual way.

D is the tubular holder that holds the wick, the wick passing through it and being held by it by means of small spurs or indentations struck in from the holder, and which engage with the wick. This holder slides up and down on the center tube with the wick.

E is the handle by which the wick is raised, said handle being attached to the holder and extending up through the top of the lamp. Devices of this kind are in common use. In

tached to the holder and is raised and removed bodily with it from the lamp. In other cases the handle is made to be detached from the holder, to allow the holder and wick to be removed from the lamp, while the handle remains permanently in place in the lamp and is engaged with the holder again when it is inserted. My improvement relates to the last-named class.

The object of the invention is to enable the v engagement and disengagement of the handle and holder to be made without turning the holder axially 011 the center tube. When so turned, it binds and the wick twists under the torsion, and it frequently becomes so tight and wedged in place that it cannot be easily raised to feed the light. In all engaging and disengaging devices of the kind with which I am acquainted this side action or turning motion of the holder takes place, the engagement being made by forked lugs engaging with a rim of the holder, a bayonet-slot, or some similar device. I accomplish the action by a straight up-and-down motion, as follows:

a is a small tubular socket attached to one side of the holder near the bottom.

I) is a vertical stem at the lower end of the handle, provided with an elongated hole d, said stem being turned upward and standing in line with the socket. When the holder is lowered, the socket strikes over the stem and no turning motion of the holder is produced.

0 is a double-sided spring pin or key, formed by bending a sprin g-wire double, the tendency of the sides being to expand. This pin is inserted through the elongated hole cl made in the stem, and rests on top of the socket to, lockin g the holder and handle together. The elongated hole prevents the pin from turning, and the elasticity of the pin produces a tight connection and keeps the parts tight, so that the wick can be adjusted up accurately and without any lost motion. To engage or disengage the handle, it is raised to the top of the lamp, where the parts can be readily reached by the fingers. The wick and holder are inserted or removed byfirst removing the burner G of the lamp, which leaves the top of the lamp open. The great advantage consists in the construction whereby the handle and holder can be connected or disconnected without turning the holder on the center tube.

In Fig. 1 the top of the handle is shown as resting looselyin a well or curb f, which forms a guide, said handle being operated simply by raising it with the hand.

In Fig. 5 the handle is shown as threaded its whole length and running through a thumbnut H, seated in the top of the lamp and turn- 5 in place.

15 by Letters Patent, is

10 of the wick-holder and removable with it.

Neither do I claim the construction of the burner shown in my pending application, Se.

vrial No. 280,569; but

WhatI claim as new, and desire to secure 1. The combination, with the center tube of a center-draft lamp, of a handle located permanently inside the lamp and provided with an upwardly-turned stem at its lower end, a 20 wick-holder sliding on the center tube and provided with an open socket on one side, said socket engaging with the stem when the wick-holder is forced down, and a suitable fastening device securing the socket to the stem, the Whole so arranged, as herein described, that the w ick-holder and Wick can be removed from the lamp Without removing the handle, as specified.

2. In a center-draft lamp, the combination of the center draft-tube B, the tubular holder D, provided With the socket a, the handle E, provided with the stem Z), that engages With the socket, and the spring-pin c, passing through an elongated hole in the stem above the socket, securing the parts and making a tight connection, as shown and described.

In witness whereof I have hereunto signed my name in the presence of two subscribing Witnesses.

HENRY E. SHAFFER.
