WM. H. ANDREWS, OF CHESHIRE, AND R. T. ANDREWS, OF PLYMOUTH, CONNECTICUT.

ALARM-TIMEPIECE FQR LIGHTING LAMPS.

To all whom it may concern Be it lmown that we, WILLIAM H. AN-

DREWS, of Cheshire, in the county of New Haven, and RANDAL T. ANDREWS, of Plymouth, in the county of Litchfield, both in the State of Connecticut, have invented a new and useful Improvement in Alarm-Timepieces for Lighting Lamps; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, which make a part of this specification, which is a perspective view of a section of the case and movement of a timepiece, showing the half cylinder in which the lamp is fitted, with the levers, springs, match, &c., which cause the lamp to be lighted by the operation of the alarm-wheel of the timepiece.

Our improvement consists in using a longitudinal section of a hollow cylinder placed vertically in the lower part of the case of the time piece, with the lamp, match, &c., placed in it, so as to be within the case when not in use, but so that when the alarm is let off the cylinder will be revolved one half of a circle, the lamp lighted and presented in front of the case of the time piece, for the convenience of the user.

We use an alarm time piece of any kind, as seen in section at A, &c. In the alarm wheel we insert a pin, as seen at B, to act on the rod C, which passes downward, (behind the bell D,) to connect with the lever, E, (which is of the elbow shape,) which works the lever F, which hold the cylinder, G, when the lamp is turned in out of sight, (while the alarm is at rest). This cylinder, G, is sustained in its posit-ion by two pivots, or bearings, in the case, one of which is seen at H, and the other is concealed by the bot tom of the cylinder. In the bottom of this cylinder, G, are two pins, or projection, (near a, and 6,) not shown in the drawing. The one near 7), rests in a spring catch, at b, to steady the .cylinder when turned so that the lamp is exposed, as shown in the drawings; and also rest against the end, or hook, 0, of the lever, F, to hold the cylinder firm when the lamp is turned in, after it has been extinguished. The pin, or projection near a, is that on which the spring I, 0, acts to throw around the cylinder after it has been released from the hook, c, of the lever F.

In our lamp, K, we have a tube, L, suited to use burning fluid, and an extinguisher, a, to extinguish it. Back of the tube, L, we fit a spring of the form shown at e, with a hole in the horizontal part to receive the match, f, while the lower end of the match is steadied in a small socket on the cap, or top, of the lamp, not shown in the drawing. This lamp, by a flange on its bottom, is held secure between the parts of the bottom of the cylinder, but may be easily removed, to serve as a hand lamp, by the user.

In the upper part of the cylinder, G, we firmly fix a piece, M, with a rough, or friction surface on its under side. This piece, M, we secure permanently to the case of the time piece by means of the pivot, or bearing, H, on which the upper end of the cylinder, G, revolves, so that the rough, or friction, surface will be always stationary, and firm, for the match to rub against. 7

Having thus made and arranged the several parts, we fill the lamp, K, with fluid, put on the extinguisher, d, insert the match, "f, (it being prepared of the proper length,) turn the cylinder, G, half around, where it will be steadied by the pressure of the spring, I, 0, against the pin, or projection, near a, while that near I), will be locked against the end, or hook, c, of the lever, F, which will be held firm by the spring, N, so that all will remain quiet until the alarm of the time piece is let off.

When the work of the time piece lets ofi the alarm the pin in the alarm wheel at B, as it comes around, will take hold of the upper end, 9, of the rod C, and by carrying it up, raise the arm, h, of the lever, E, and thereby bring the arm, i, against the lever F, so as to'force back the end 0, and unlock the cylinder; when the spring I, 0, will carry the cylinder, G, half around, to the position shown in the drawing. And as the cylinder, Gr, revolves, the piece M, will remove the ex tinguisher, d, and the end of the match, rubbing against the friction surface, will be ignited, and so light the lamp. Should the match be a trifle too long, the spring 6, will allow it sufficient play to prevent injuring the match.

What we claim as our invention, and desire to secure by Letters Patent, is

The use of a revolving vertical section of a cylinder, (as G,) when combined with a spring, (as I, 0,) to revolve it, when these and arranged, substantially as herein deare combined with the appropriate levers, scribed.

(as E, and F,) and connected with the alarm WM H ANDREWS wheel (as B of an alarm time piece by an 5 appropriate connecting rod, (as (3,) for the RANDAL ANDREWS purpose of lighting a lamp in connection Witnesses: with the alarm given by an alarm time piece, R. FITZGERALD,

when the whole is constructed, combined, r F. W. J. SIzER.
