IM PRQVEMENT IN CANDL'ESTICKS.

Speciiication forming part of Letters Patent No. 198,660, dated December 25, 1877; application tiled August 6, 1877.

To all whom 4it may concern:

Be it known that we, FRANoIs ROMAIN 'MINARD and ARMAND PIERRE MINARD, of the by the adhesion `of the candle, caused by the melted matter, is quite overcome by the powerful action of a screw. As to elegance, the form and design ofthe can dlestick are uninj ured by the absence of the external knob and slit or groove in the stem.

In the accompanying drawings, an Ordin ary tall candlestick is shown having our improved screw-lift. The same mechanism is suitable toilat or other candlesticks.

Figme 14 is an elevation of a candlestick embodying our invention. Fig. 2 Vis a vertical section, showing the combination and disposition of the new parts 5 Fig. 3, a horizontal section, following the line l 2; and Fig. 4, an external view of the screw-lift.

On the stem of the candlestick a the external caseb is fixed, which turns at c and forms the covering` to the socket d, in which the lower end of the candle is inserted. This socket d is a tube, open at both ends, and shaped to cover the piece b by a shoulder, e, above, where it is solid with it. The piece b terminates at the top in a rim or projection, e, which adjusts itself loosely in a groove or circle in the crown f of the socket, this screw being soldered to the socket when the parts are put together. l

In the socket are two grooves or vertical spaces, h, which are the guides to the screw c. This is a double and square threaded screw,V moving in the screw c of the head of the candlestick. At the upper end of this screw is a plate, t, acting as a piston in the tube or socket d, andwhich moves with the tube by aid of two tenons or wings, g g, made on'the circumference of the piston t, and which engage in the spaces h of the socket-tube d.

The action of the screw-lift or candle-regulator is as follows: In turning the crown f of the socket d to the right or left, a corresponding or up-and-down motion is imparted to the head or piston t of the screw c, the screw c serving as fulcrum. This movement causes the candle to ascend or descend, as required.

For increasing or decreasing the speed of the screw the pitch of the thread is correspondingly arranged, and a suitable number of threads made on it.

The system of candlestick described and illustrated as embodying our invention is therefore essentially characterized by the screw-lift v, which advantageously replaces the ordinary button and slot or groove, and has, like it, the object of moving at will the seat or plate t of the socket d, on which the candle rests, which movement is the result of the combination' of a screw, the head of which forms the seat of .the socket, and by turning which to the right or left, by means of the crown f, a simultaneous elevation or descent of the screw is effected, and consequently the candle rises and, descends in like manner.

The form and dimensions of the parts and the material of construction would naturally vary to suit the form of the candlestick, and the same mechanical arrangement may be equally applied to Candlesticks, lusters, chandeliers, and all kinds of candle-holders.

Y We claim as our invention- The double and square threaded screw c, guides h, screw c, and plate or piston t, in combination with the movable socket d, shoulder e, tenons g, and crown f, as and for the purposes precisely as herein described.
