IMPROVEMENT IN CANDLE LAMPS C R HOLDERS.

Specification forming part of Letters Patent No. 123,803, dated February 20, 1872.

To all to whom Athese presents shall come:

Be it known that I, MARTIN WEIs, of Boston, in the county of Suffolk and State of Massachusetts, have made an invention of a new and useful Improvement in Candle Lamps or Holders; and do hereby declare the following to be a full, clear, and exact description thereof', due reference being had to the accompanying drawing making part of this specification, and in which- Figure l is a vertical section; and Fig. 2, a horizontal section of a portion of a lamp containing my improvements.

This improvement is based upon a class of lamps now extensively in use in railway cars, made to receive a large candle, which is forced up to a certain point and maintained there, as

it is consumed, by the agency of a spiral spring placed below it, the candle and its skeleton frame and spring being contained within a tubular case, which is attached to the base of the globe by aspring-catch and clutch.

The accompanying drawingrepresents, at A,

ythe annular base of a candle lamp or holder,

and to which is secured the glass globe B in the ordinary manner. C represents the open or skeleton frame which contains the candle, and l) the spiral spring', which is disposed within the frame and below the candle, and serves by its expansion to maintain the candle in contact with the conical cap-plate -E, which surmounts the frame G. F in the drawing represents the tubular case which receives the frame O and candle, the two being united by an adjustable connection. To the upper part of the case F an enlarged annular concave ring, G, is attached, this rim having aseries of projections, a a, &c., to interlock with a corresponding series of projections formed upon the inner periphery of the annular base A before named, the joint thus produced being one in common use. H represents a horizontal bolt, which plays in an orice, I, created in the rim Ghand projects a short distance beyond the exterior of the latter, the innerend of this bolt being affixed to a harp-shaped or curved spring, J, which partially or Wholly surrounds the upper portion ofthe tubular case F, and is disposed within the rim G, the free ends of the center of this spring, as the case may be, being secured to the rim at a point opposite the bolt H. A rod, K, is attached to the spring J immediately below the bolt H, and passing through the rim Gr is provided at its outer extremity with a knob or button, L, by means of which the bolt is forced inward beyond the exterior of the said rim. The bolt H operates, in connection with one or more notches, b, formed in the interior of the annular base A, 'to lock the tubular case F and its contents to such case. The noyelty in this improvement consists in the character of the bow or annular spring J, which operates the bolt H. Heretofore this spring has been a single-acting one-that is to say, the bolt H has been aflixed to the free or dis; engaged end of a simple platespring, the opposite end of which has been secured to the interior ofthe rim Gr at a point more or less remote from the bolt. has been found inadequate, in many instances, to securely hold the case F and its contents in place, as the bolt has frequently been misplaced and retracted by the twisting or rotating motion imparted to the case F in the attempt to insert the base-plate of the candle holder or frame Owithin the said case, as the spring, being confined at one end only, yields before the pressure, and permits a retraction of the bolt without pressure upon its thumbknob L. This accidental retraction of the bolt and sundering of the connection of the case F and its contents with the rim and globe frequently occurs by means ofthe thrusts and concussions resulting to it while the car is in motion, and the case and candle, in such event, fall to the door of the car. By means of my double-acting spring the pressure upon the bolt is exerted with equal force upon cach side; consequently the bolt has no tendency' to leaveits socket in the base A. As herein shown, the spring J is in the form of a deep bow or harp, withits two ends secured independently to the rim G but I may prefer rrrcn.'
