TIMEL GAS-LIGHT EXTINGUISHER.

SPEGIFIGATIQNforming part of Letters Patent No. 760,844, dated May 24,

Application filed October 27, 1903. $erial No. 178,680. (No model.) i

T0 at whom it mdy concern:

Be it known that I, PHILIP E. N EWsoM, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Automatic Apparatus for Extinguishing Lights, of which the following is afull, clear, and exact description, such as will enable others skilled in the art'to which it'appertains to make and use the same. My invention relates to an apparatus for automatically extinguishing a gas-light at a predetermined time, although it may b'e'used for extinguishing other kinds of" lights; It has for its object'to provide a simple inexpensive device of this'character that will operate easily and .surely. Other objects will appear from the hereinafter description."

The invention consists in certain novel features of construction; and combination of parts, all as hereinafter fully set forth in this specification, and particularly pointed outinthe claims thereof.

Referring to the drawings, which form a part of this specification, and in which the same reference characters represent the same parts in the different views, Figure 1 is a rear view of the apparatus attached to a swinging or Fig. 2 is asection on the line-2 of Fig. 1. Fig. 3 is a section on line 3 of Figs. 1 and 2. Fig. 4 is a detailedsectional-view, on an enlarged scale, of certain parts of the mechanism for automatically ex- 'tinguishing the light, this section being taken on the line 4 of Fig. 1. Fig. 5 is .a detail View of certain parts illustrated by Fig. 4, some of the .parts being in a different position from that shown in Fig. 4. Fig. 6 isa front view of certain parts shown in Figs. 4 and 5.

Fig. 7 is a detailed sectional view on the line 7 ofFig. 1, showing certain parts of the mechanism for extinguishing the light and means for starting and stopping said mechanism. Fig. 8 is a front view of certain parts of the mechanism shown in Fig. 7, taken on the line 8 of that figure. The part marked 1 on the drawings repre sents the gas-pipe of the swinging gas-fixture. 2 is the burner, and 3 is the valve bywhich the gas passing through the pipe is turned on and off from the burnen 4 is the casing, secured to the gas-fixture. Mountedin this casing is an arbor 5, the upper end of which is bifurcated and connected to the valve The lower end is journaled in the lower part o'f-the'casing 4, this "end pass ing through the casing-and having secured thereto the lever 6.

7 is acoiled spring, the inner end ofwhich is secured to the'arbor, andthe outer end is secured to one side of the casing by a screw 8, as shown in Fig. 2. i i

1 Ms astop or pin'projecting from the lower end of the casing and against which the lever rests when the apparatus is not" set for extinguishing the light. When the lever is turned from the pin, it turns thearbor and Winds or puts the springunder'tension. Pivoted to the rear side of the casing 4 and projecting downwardly therefrom is aswinging stop 10;-

which is recessed at 11, leaving a finger 12- 14 represents the casing of the clock mech anismshown in rear view of Fig. 1, which is suspended from the gas-fixture by the straps 'orr0ds15.- V I 16 represents what corresponds to the ordinary alarm dial-clock, having a finger or pointer 17sccu'red to the arbor 18. Y Secured to the .front end of this arbor is a small disk 19, having a projection or finger 20 thereon.

21 is a gear-wheel loosely mounted on this arbor and which-has a collar 22,- which is thrown over the disk 19. "Whenthis gearwheel is turned to a certain position, the pin 20 of the disk 19 bears againstthe forward edge ofthe "collar until the gear wheel is vmoved such a position by' -the clock mech-.

anism" 'that the cam-recessi-23 in the collar 'c omes opposite the pin 20, when the gearwheel and collar are thrown overthe disk. one a spring secured to the forward frame 25 of the'clock mechanism. This spring rests against the inner face of the gear-fwheel 21 and tends to move the gear-wheel forward or laterally on the arbor 18. W The inner-end of- 1 thisspring is-inturned, forming-afinger-26:

27 is a shaft or arbor pivoted into the front and rear frames 28 and 29 of the clock mechanism. 30 is a finger secured to this arbor, and 31 is an arm also secured to the arbor and carrying a weight 32, which moves the arbor in a certain direction. 33 is another arm secured to this arbor, the free end of the frame being bent at right angles and extending through the slot 34 in the rear face of the clock and against which the end 13 of the arm 10 rests when the mechanism is set. The finger 26 of the spring 24 comes in the path of movement of the finger 30 and holds the arbor 27 in a set position to be described.

This apparatus operates as follows: Suppose,for example, it is desired to extinguish the light at twelve oclock. The arbor 18 is turned until the hand 17 points to the hour 12, as shown on Fig. 1 of the drawings. As the arbor is moved it carries with it the disk 19, carrying the finger 20, which forces the gearwheel 21 inwardly, thus forcing-the finger 26 of the spring 24 over the arm 30, so that this arm cannot be moved upwardly or the arbor 27 rock, the arm 33 being in the position shown in Fig. 1 of the drawings. The clock mechanism is now set. The lever 6 has moved from its stop 9 for winding up its spring, and during this operation the spring on the arbor 5 iswound up. The free end of this lever strikes against the swinging arm 10 and moves it into the position shown in dotted lines in Fig. 1. Then the lever is released, and the free end moves in the recess 11 of this arm. The swinging arm moves backward against the arm 33 and is held in position against further movement by this arm 33. The finger 12 prevents the lever 13 from moving back to its original position. The parts are now as shown in Fig. 1 and the gas-valve turned so thatthe gas can pass through the gas-pipe to the burner 2. At twelve oclock the gear 21 has been moved by the clock mechanism to such position that the cam-recess 23 therein will be opposite the finger 20 of the disk 19, at which time the spring 24 throws the gear forward, and the finger 26 is carried out of the way of the arm 30. At this time the arm 33 no longer holds the swinging arm set when the lever 6 is released, and the coiled spring? turns the arbor 5, whereupon the valve 3 is turned to cut off the gas.

The means for starting and stopping the clock mechanism will now be described.

40 is the arbor of the clock mechanism, to one end of which the hair-spring 41 is secured, 42 being the balance-wheel'mounted on the arbor. This balance-wheel has also secured to it the pin 43, which meshes with the teeth on the lever 44, mounted on the escapementarbor 55, the escapement-lever being shown at '46, which is in contact with the escapementwheel 47, mounted on the arbor 48. This arbor has secured to it the pinion 49, which is driven by a train of gears leading to the mainspring. (Not shown.) Secured to the rear frame 29 of the clock mechanism is a spring 51. having an inturncd end of linger 52, which is normally out of contact with the lever 44.

53 is a push-button extending through the rear casing of the clock and through the frame 29 and has an eye 54 on the forward end thereof, through which the spring 51 passes. \V hen it is desired to stop the cloekmcchanism, this push-button is pushed inwardly, when the free end 52 of the spring is thrown in contact with the lever 54 and holds the lever from rocking and prevents the escapement-arbor from rocking, whereby the clock mechanism is stopped. from operating. When the pushbutton is released, the lever is permitted to rock in the usual manner. If the mainspring of the clock mechanism is wound, but the mechanism is not operating when the button is moved in and released quickly, the finger 52 of the spring will strike the lever 54 and rock the lever, whereupon the escapementarbor is rocked and the mechanism is put in motion.
