UNITED STATES PATENT, OFFICE.

CHARLES F. WALDR'ON, or BosToN, MASSACHUSETTS.

CARRIAGE-LAMP.

SPECIFICATION forming part of Letters Patent No. 333,365, dated December 29, 1885.

Application filed February 13, 1885. Serial No. 155,811.

To all whom it may concern:

Be it known that I, CHARLES F. WALDRON, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massach usetts, have invented certain new and useful Improvements in Carriage-Lamps; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.

This invention is in the nature of an improvement on that set forth in the Letters Patent No. 280,101 granted to me June 26, 1883, for carriage-lamp. In said patent I showed a lamp adapted to consume a candle pressed upwardly by a spring; and a peculiarity of that invention was a cap having near its top an inward bead for the upper end of the candle to press against, and above the outward swell or bead an inward-turned bar rier to prevent slopping the melted wax or tallow. The foot of the candle rested on the upper edges of a cup seated within the top coil of the supportingspring.

My present improvement relates to the same class of lamps, and accomplishes the same results by somewhat different means. The cap is destitute of the inward head, but has the inward-turned barrier at its extreme top, and gradually enlarges from that point downwardly. Within this tapering cap is a candle-tube distinct from the cap, and having at its top the inward bead or an equivalent annular rest for the candle, serving to keep it from being pressed upwardly too far. The upper edge of this tube above the head is pressed against the tapering inner surface of the cap. The cup at the foot of the candle rests in a tube or sleeve within which the supporting-spring is secured.

In the drawings, Figure 1 shows in section a lamp provided with my improvements. Figs. 2 and 3 are enlarged details. Fig. 4 is a modification of the candle-tube.

A is the cylindrical candle-tube having near its upper end the inward bead, B, against which the candle O is pressed by the spring D.

F is the cap, spun up from a disk of sheet metal and given a tapering form, about as shown. At its extreme upper edge is a horizontal barrier, G, turned inward toward the candle-wick. The flaring upper edge, E, of

(No model.)

the tube bears against the tapering inner wall of the cap at a point just below the barrier G, the contact being close owing to the upward pressure of the spring, and the parts being proportioned to each other. I prefer to solder the tube permanently in this position within the tapering cap. By this arrangement a chamber is formed around the top of the candle by the tube and cap conjointly to retain the melted wax or tallow, so that it shall not be slopped over or thrown out by any ordinary movements of the vehicle.

In the manufacture of these candle-tubes I propose to make the cylindrical part of tin, with the seam closed by solder, and to form the beaded top ofit of a grooved continuous ring of thin brass soldered to the end of the tin tube. I sometimes employ the construction indicated in Fig. 4, where an equivalent for the bead B and edge E is formed by securing a beveled ring, H, at the top of the tube as a stop for the candle. The candle is pressed against the bottom of the ring, and the outer edge of the ring bears against the tapering cap, as in the corresponding parts B E in the other figures. The foot of the candle rests on the upper edges of the flanged metallic cup K at the top of a tin sleeve, L, which surrounds the upper end of the spring, to which it is secured. The body of the spring is inclosed in a bag or wrapper to prevent it rattling in the long stem of the lamp, as usual.

It is not essential that the cap F should have the uniform taper shownin the drawings.

I disclaim the construction shown in the patent on candle-lamps, No. 105,020, granted to Williams and Taber, July 5, 1870. In said patent a slotted plate or shield is introduced between the upper end of the candle and its flame, the slot allowing the wick to protrude through and be lighted above it, while the shield prevents the direct radiation from the flame downward to retard melting the wax. Furthermore, said patent does not provide an annular barrier above the melted wax to prevent its slopping; but the top of the candletube flares outwardly and does not come into contact with the inner surface of the cap, thus differing from my device in two essential features. My improvement, therefore, insures a much stronger light, since I provide abundant food for the flame; and by the joint 3eward bead or ring B, and heldfirmly in con-" tion of the tube and cap an inelosed chamber tact with the inner surface of the cap F, sub is formed, preventing the melted wax from stantially as and for the purpose set forth.

spilling down inside of the lamp. In testimony whereof I heretoaffix my sig- 5 I claim as my invention nature in presence of two witnesses.
