PHILIP E. NEWSOM, OF NEW YORK, N. Y.

SPECIFICATION forming part of Letters Patent N 0. 736,538, dated August 18, 1903.

Application filed February 20, 1903. Serial No. 144,225. (No model.)

To all whom it may concern.-

Be it known that I, PHILIP E. NEWsoM, residingat the borough of Brooklyn, city of New York, in the county of Kings and State ofNew York, have invented certain new and useful Improvements in Automatic Apparatus for Extinguishing Lamps, of which the following is a full, 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 apparatus for auto-v matically extinguishing a 1ight,and especially an oil-lamp, at a predetermined time, and has for its object to provide a simple, inexpensive, and easily-operated device of this character. Other objects will appear from the hereinafter description.

The invention consists in certain novel fea tures of constructions and combinations of parts, all as hereinafter fully described and claimed.

Referring now to the drawings which form a part of this specification, and in which I have illustrated my device as applied to an oil-lamp, Figure 1 is a rear elevation of the apparatus. Fig. 2 is a detail View of certain parts thereof. Fig. 3 is another detail View with certain parts in different position from that shown in Fig. 2. Fig. 4 is a front view of certain parts shown in Figs. 2 and3. Fig. 5 is an illustration of the extinguisher as ap plied to the lamp-burner. Fig. 6 is a front View of the device shown in Fig. 1, and Fig. 7 illustrates a modification. 7

Referring now to the drawings, in which the same reference-letters indicate the same parts in the different views, A represents a clock, by the mechanism of which the extinguisher is released.

B represents a lamp, and 0 represents the burner of the lamp.

The clock consists of the usual mechanism by which the extinguisher, hereinafter to be described, carried by the lamp-burner, is released.

D is the front frame, and E is the rear frame, of the clock mechanism.

F is a shaft mounted in the frame, having on the rear end thereof a key f, by which it maybe turned. To the front end of this shaft is attached the hand Gr, shown on the face of the clock, adapted to be set at an hour at which the light is to be extinguished.

H is a disk also secured to the shaft inside of the face of the clock and having connected thereto a finger or log h.

J is a gear-wheel loosely sleevedon the shaft F inside of the disk H and is driven by the mainspring K of the clock mechanism through the series of gear wheels and pinions K K K &c.

J is a ring or band connected to the gear J, having a recess J in the outer edge thereof, which has an inclined face J The internal diameter of this band is such that it will fit over the disk H when the finger h of the disk is in the recess J of the band.

J is a sleeve secured to the inside face of the gear J and against which the spring L rests. This spring is attached to the frame D and has the free end thereof inturned into a finger, as shown at L. The spring rests against the sleeve J" and tends to force the gear toward the forward end of the shaft E. The finger h, bearing against the edge of the band J except when the notch or recess J is opposite the finger h, keeps the spring pressed in.

M is a rock-shaft pivoted between the frames D and E. m is an arm connected near the front end of this shaft in such position that it comes in contact with the finger of the spring when the finger is pushed in. N is an arm connected near the other end of the rockshaft M. The free end of this arm rests in a notch O of the rear frame E of the clock mechanism.

C is the bottom plate of the burner, and O is the wick-tube secured thereto.

P is the extinguisher pivoted to the burnerplate 0.

Q is a rod, one end of which is connected to the extinguisher at q, and the other end is bent or curved, as indicated by q, in such manner that the rod can be held by the arm N, heretofore described. R is a coil-spring surrounding this rod, one end of the spring being connected to the burner-plate G and the other secured to the rod, so that it tends to move the rod upwardly and throw the ex tinguisher over the top of the wick-tube.

The apparatus operates as follows: Suppose it is decided to extinguish the light at nine oclock, for example. The shaft F is turned by the keyf until the small hand on the face of the clock (shown in Fig. 6) points to 9. When in this position the finger h of the disk H will be on the outer edge of the collar J, and the gear J will be moved inwardly. pressing in the spring L, so that the finger L thereof will be in the path of movement of the arm m, so that the shaft M cannot be rocked. In this position the arm N will be seated in the notch O of the rearframe E, as shown in Fig. 1 of the drawings. The

rod Q is now pulled down, and the bent end q catches under the arm N, whereby the rod is held down against the tension of thespring R, and the extinguisher P is pulled down from over the lamp-wick, so that the light will burn in the usual manner. The parts will stay in this position until the hourof nine arrives. At this time the gear J will have been rotated by the clock mechanism, and the recess J in the edge thereof will come opposite the finger h, when the spring L will force the gear J out to the position shown in Fig. 3, with the finger h of the disk H in the recess J of the ring J. The springfinger L is now out of engagement with the arm N, and the lever may now be rocked. The spring Rwill then pull on the rod Q, and the arm Nwill be raised out of its seat 0, permitting the rod to be released and pulled up, whereupon the extinguisher P will be thrown over the upper end of the wick-tube and extinguish the light. To reset the device, the shaft F is again turned by the key fto the right, whereupon the finger will ride out of the recess J on the incline surface J of the recess, when the gear willbe forced inwardly, moving with it the spring L, so that the finger L thereof will again come in contact with the arm M to hold the arm N in its seat 0, so that the rod can be again held down by the curvedlower end q thereof hooking over the arm and holding the extinguisher away from the light against the tension of the spring R.

In the modification that I have illustrated in Fig. 7 the clock mechanism is placed in one room and the lamp B in another, and the rod Q is bent, so that it will pass from one room to the other through an opening, as shown at S. The spring R in this case has its upper end secured to a bracket O and the that I may use the same device for extinguishing electric and other lights.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1.
