COMBINED ALARM-CLOCK AN D LAMP-REGULATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 313,300, dated March 3, 1885.

Application filed May 2, 1884.

To all whom it may concern.-

Be it known that 1, JOHN M. CRAWFORD, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Illuminated Clocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification, in which Figure 1 is a front elevation; Fig. 2, a rear elevation; Fig. 3, aside elevation, and Fig. 4 a perspective of detail.

The intent of my invention is to efi'ect, by means of olock-work acting on an oil-lamp, the periodical illumination of an apartment or other space, and reciprocally the lighting up of a dial of a clock, so as to permit visual observation of the time indicated thereby.

A still further object of my invention is to combine with an alarm-clock an oil-lamp in such manner that when an alarm is started by the clock the light of said lamp shall be raised from a glimmer to a full or enlarged flame, so as to illuminate an apartment and make the clock-dial plainly visible.

The peculiar construction,combination, and arrangement of parts hereinafter fully stated comprise my invention.

In the accompanying drawings, Aindicates an oil-lamp provided with a wick and having a shaft, B, whereby such wick may be raised and lowered to increase and diminish the flame of the lamp.

0 is a clock of any suitable construction, preferably a portable spring-clock having a dial. The lamp A and clock 0 are secured to a base, D, with the lamp in advance; but to one side of the clock, so that when its flame is sufficiently raised it will illuminate the dial while not obstructing the view of the latter, either directly from the front or from'either side of the clock. The clock may be, and preferably is, rigidly secured to the base D, while the lamp is detachably fastened by means of screws 6 e and a button, 6, so that it can'be removed from said base to permit replenishment, cleaning, 8m. 7

On the outer end of wick-shaft B is firmly fastened a disk, F, having around or near its edge and closely together a series of openings,

(No model ff, into one of which at a time enters the wrist-pin g of a crank-shaft, G, sustained on a standarchH. Said standard consists of two pieces, h and h, the piece h being secured to the base D by screws or equivalent fastening, while the piece h is formed witha vertical slot, h", and is secured to the piece h by asetscrew, h passing through said slot., By these means the piece h may be moved up and down on the piece h, and the altitude of shaft G adjusted to fit lamps of various heights.

The purpose of the series of holes in the disk F is to have one always aligned with the wristpin notwithstanding said disk will be rotated as the wick of the lamp is trimmedfrom time to time.

The shaft G carries at one end a disk, G, having an opening or openings, 9, for the reception of a pivotal screw, 9 whereby it is attached to a pitman, I, which forms the medium of connection with the clock 0. The opposite end of said pitman is pivotally secured by a screw, 2, to a disk, K, or equivalent three-a-rmed lever loosely journaled by its center ]i') on the back 0 of the clock-case. \Vhen said disk is partially rotated, it will produce, by means of the pitman I, a corresponding rotation of the shafts G and B and a raising or lowering of the wick, according to the direction of such rotation. To produce such rotation in one direction, the disk K is formed with a lug or projection, is, against which will abut, forashort period of time and successively, one of the series of arms Z Z of a cross, L, secured rigidly to the arbor M of the minute-hand of the clock. This will cause the lamp-wick to be raised.

To produce a contrary rotation or reverse motion of disk K aiter an arm Z has cleared lug k, and thereby to lower the wick,a spring, N, is provided, having its lower end secured to base D, and its upper end fastened to a lever,O, connected, as shown, by one end to said disk, its other end having apivotal connection with the lower extremity of a lever, P. Said lever P is approximately of V shape, and is journaled at its apex on the winding-arbor Q of the clock. Its upper arm, p, inclines to- IOC tion.

said nut has a pivoted dog or latch, 8 which may stand aligned with the nut-Wings and transverse of the axis of said arbor, or may be turned so as to be parallel with said axis, in which latter event it will intercept and raise the upper end of lever 1? when the alarm is set going and shaft R rotates. Lever P being attached to lever O and latter to disk K, the result is that when alarm goes off the lamp-wick will be raised. As long as the alarm-arbor rotates the illumination thus produced will be intermittent; but as soon as such rotation terminates the illumination becomes permanent, as the dog 8 will then remain in contact with the arm 1) of lever P, and the latter will stay raised until lowered by hand.

To afford means for sustaining the wick raised to give a full flame, I provide a rock-shaft, T, mounted in suitable bearings on the base D, and having at one end a crank-handle, t, and at the other an arm, t, which latter, when said shaft is rocked by means of said handle, will impinge against and raise the lower arm of lever P, dogging and sustaining the latter until turned back to its normal position by hand. If desired, the arms of the cross L may have pivoted wings Z, as in my patent No. 281,465.

To alter or vary the throw of the pitman I, and thereby to adjust the extent of elevation and depression of the wick, the disk K has two series of radial openings, k for the reception of the pivots connecting the levers P and O therewith. The-nearer said pivots are brought to the center of said disk the less will be the movement of the wick.

The operation is substantially as follows: The parts being duly adjusted the lamp will be turned down to a glimmer or faint light. At periodical intervals say every quarter of an hour, or more or less frequently-one of the arms lor its wing will come in contact with the projection 70 and effect a partial rotation of the disk K, thereby causing the elevation of the lamp-wick to the extent desired or necessary to produce a full flame or increased illuminaand enable the time indicated thereon to be observed. As soon as the arm Z passes the lug k the spring N will effect a reverse motion of disk K, and thereby produce the lowering of the wick. hen the alarm starts, the wick is also raised and remains raised until turned down by hand, and when it is desired This will render the clock-dial visible to maintain a full flame without waiting for the alarm mechanism the rock shaft T is moved, as already described.

What I claim as my invention is as follows:

1. The combination, with an oil-lamp having a wick and ashaft for raising the same, of a clock and an intermediate shaft connected with the wick-shaft and the works of the clock, whereby the movement of said works will produce an elevation of said wick, substantially as shown and described.

2. The combination, with the wick-shaft B and crank-shaft G, of a disk, F, having a series of openings for the reception of the wristpin 9, substantially as shown and described.

3. In combination with the crank-shaft G, the vertically-adj ustable standard H, substantially as shown and described.

4.. The combination of wick-shaft B, disk F, crank-shaft G, carrying disk G, pitman I, and disk K, journaled on the clock-case 0, substantially as shown and described.

5. The combination,with cross or lever L on the minute-hand arbor of the clock, ofthe disk or lever K, having projection 6r lug in, substantially as shown and described.

6. The combination,with the lamp A, having wick-shaft B, with disk F, and clock 0, having a cross or lever, L, on its minute-hand arbor, of the intermediate mechanism consisting of crank-shaft G, pitman I, disk K, with lug lo, and spring N, whereby the lamp-wick is raised and lowered, substantially as and for the purpose set forth.

7. The combination,with disk or lever K, of levers O and P, substantially as shown and described.

8. The combination,with alarm-arbor R, of nut S, having a pivoted dog or latch, 8", substantially as shown and described.

9. The combination, with alarm-arbor R, having nut S, of levers P and O and disk K, substantially as shown and described.

10. The combination, with levers O and I and disk K, of rockshaft T, having crankhandlet and arm 26, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 29th day of April, 1884.

JOHN M. ORAVVFORD.
