SUPPORT FOR INCANDESCENT MANTLES.v

SPECIFICATION formingpart of Letters Patent No. 760,814, dated May 24, 1904. Application filed November 10,1903. Serial No. 180,591. (No model.)

To all whom, it may concern.-

' Be it known that I, ALLEN N. SPooNER, a

citizen of the United States, residing at the city of New York, inthe borough of ,Manhattan and State of New York, have invented certain new and useful Improvements in Supports for Incandescent Mantles, of which the following is a full, clear, and exact description.

This invention relates to incandescent gasthe chimney, so that the combined-devices may constitute a single article of manufacture.

My improved support consists, essentially, of a cross-wire having its ends seated in two diametricallyarranged perforations in the chimney and its middle portion provided with a bend or loop in which the usual loopon the mantle is seated.

The invention will be described in detail, with reference to the accompanying drawing, in which the figure is .a vertical section of a lamp-chimney, showing the burner, mantle,

and support in side elevation.

The burner is indicated by A, the mantle by B, and the chimney or shade by C. The fixture includes the usual bracket or support a for the chimney.

At diametrically opposite points and at a suitable height the chimney is provided with two perforations 0 and c. In the case of a mica chimney these perforations may be reinforced by eyelets; but in the case of a glass,

chimney the reinforcing isnot required, the holes being merely drilled in the glass.

6 is a cross-wire constituting the support for the mantle. It is preferably of platinum to withstand the heat; but it may be of iron or any other refractory metal'or material. The length of the wire is slightly greater than the diameter of the chimney, so that when its two ends are inserted in the holes 0 0 they can be bent laterally on the outside of the chimney to retain the wire in place' At the middle point of the wire it is provided with a loop or bend e, furnishing a seat for the usual asbestos or wire loop I) at the upper end of the mantle.

. Asupport of this character can be removed and replaced very easily and without tools. One of the projecting ends of the wire is simply bent out straight and the wire then drawn out, the mantle being disconnected by drawing the wire through the loop 6. To mount a new mantle, thesame is held within the chimney while the wire is threaded through one of the perforations c, then through the loop 5, and finally into the other perfora-- tion 0.

A support of this character, which may be made a substantially permanent part of the chimney, renders it feasible to assemble the 'collodion-dipped unburned mantle with the chimney by attaching the mantle to the support. The combined chimney, mantle, and support may then be packed, shipped,and sold as a single article of manufacture ready for use.. The subsequent renewals of mantles would then be attended to by the user in the manner above described.

I am aware that supporting wires or frames for the mantle have heretofore been attached to the chimney; but I do not know of. any such permanent arrangement as I have devised nor of any such simple device.

Having described my invention, I claim In an incandescent gas-light, a mantle-sup- ALLEN N. SPOONER.
