SPECIFICATION forming part of Letters Patent No. 616,770, dated December 27', 1898. Application filed April 1,1898. Serial No. 676,077. (No model.)

0 all whom it may concern:

lle it known that we, CHARLES S. COLE and JOHN II. KINSMAN, citizens of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Lighting or Extinguishing Automatically Incandescent Electric Lamps; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

Our invention relates to mechanism for turning on and shutting off incandescent electric lights at any predetermined timein stores or other places in which a light or lights are kept burning during the night. Itis the usual practice to turn on the light in closing the store in the evening and shut it off in opening up in the morning. This is frequentlya source of waste, especially in summer, as the lights are kept burning much longer than necessary, owingto the shortness of the nights.

The object of our invention is to provide improved means whereby the lights will be automatically turned on and cut oil at any desired time.

The invention consists in the novel construction and combination of parts hereinafter fully described'and claimed.

In the accompanying drawings, Figure 1 is a rear view of an apparatus constructed in accordance wit-h our invention, the clock being removed. Fig. 2 is a detail front view, the clock being in place. Fig. 3 is a transverse sectional view.

In the said drawings the reference-numeral l designates a wooden or other non-conducting casing, the top of which consists of a metal conducting-plate 2, upon which the clock 3 rests. This clock may be what is known as the lVaterbury or other metal clock. If the clock is not of metal, theworks must be electrically connected with the conductingplate 2. Secured to the inner side of the front of the casing are two metal conductin L 6 plates 4 and 5, having upward extensions formed with semicircular recesses 6 in the inner sides. These plates are separate and distinct from each other, and the clock sits between said recesses with the dial. The plate upon which the clock rests is located far enough back from the upright metal plates to be out of contact with them and to allow the adjustable contacts to revolve without touching them. In rear of said recesses are semicircular slots 7, in which are located rotatable contacts, which by the engagement therewith of the hour-hand of the clock make and break an electric circuit which controls the lamp or light circuit, as hereinafter described. Thesc contacts can be freely moved in the semicircular slots and are retained in any desired position by a flange and thumbscrew. The plates at and are each made of two pieces hinged together a short distance above the wooden front in order that either side may be turned down whenever it is desirable that one or both of the revolving contacts should not be actuated by the hourhand. Another rotatable contact is placed in a fixed position in the upper portion of one of the upright plates from which it is insulated. It is also actuated by the hourhand. This contact has only one conductingarm, the others being of non-conducting material. Its use is to cause a bell to ring to call attention to the fact that the clock should be wound. The number of arms is equal to the frequency with which it is desired to wind it. It is in electrical connection with the 10- cal battery and the bell, (not shown,) which may be placed wherever convenient.

Located on the bottom. of the casing are two independent electromagnets 8 and 9, the coils l0 and 12 of which are connected as one with a conductor 13, leading to binding-post 14. This binding-post is connected by a conductor 15 with an electric battery 16. The other pole of the battery is connected by conductor 17 with a bindingpost 18, which in turn is connected by conductor 19 with the conducting-plate 2 at the upper end of the casing. The other end of the magnet-coil 10 is connected by means of conductors 20 and 21 with contact-bl0cks 23 and 28, respectively, secured to the front of the casing. The other end of the magnet-coil 12 is connected by cond uctors 25 and 2b with contact-blocks 21: and 97, respectively, in line with and similar to blocks 23 and 28.

The numeral 29 designates a switch consisting of a rectangular non-conducting bar located in a groove in the front of the casing and adapted to slide horizontally therein. This bar is provided with two contact-strips 30 and 31, the upper ends of which contact, respectively, with the plates l and 5, while the lower ends are adapted to contact with blocks 23 and .t or 27 and 28, as the case maybe.

The numerals 32 and 3-1: designate bindingposts at opposite sides of the casing, each of which is provided with an inwardly-extendingconducting-strip These strips almost, but do not, meet at the center of the casing, and are pivotally connected with the bindingposts, and are in electrical connection with an electric-light circuit.

Located centrally above the electromagnets is a rocking or oscillating balanced armature comprising the arms 36 and 37 and an upwardly-extending arm 38, provided at its upper end with a non-conducting segment 39, having on its upper side a metallic strip TO, by which the circuit between the strips 33 is made and broken. This armature is so balanced that when one of the arms 36 or 37 is depressed by the attraction of either of the magnets and the current broken it will remain in such position until the other magnet is energized, when it will be attracted thereby and its position reversed.

The numeral l1 designates screw-threaded pins passing through the slots in plates t and 5, on which are journaled tubes &2, provided with alternately-arranged long non-conducting and short conducting arms e8. A fixed washer 45 and a movable screw-nut 16 hold these pins in their adjusted positions.

The numeral 47 designates a rotatable rod passing through the front of the casing and provided with arms i8, by which the armature can be rotated by hand if desired to turn on and shut off the light.

The operation is as follows, looking from behind, which of course reverses apparently the motion of the hand: Supposing the hourhand to be at twelve m., or noon, and it is desired to have the light turned on at five oclock in the evening and shut off at eight oclock in the morning, then the rotatable contact at the left of the apparatus, as seen in Fig. 1, which represents the second revolution of the hand, as hereinafter described, is adjusted so as to come opposite the figure 5 on the dial, and one of the conductingarms thereof is turned so that it will lie in the path of the hour-hand of the clock. The other rotatable contact is adjusted so as to come opposite the figure S on the dial; but one of the non-conducting arms will lie in the path of the hour-hand. As the hour-hand moves it will come in contact with the 0011- ductingarm of the contact at the left, when an electric circuitwill be established, turning on the light. The circuit is as follows: from battery by conductor 17 to bindingpost 18, conductor 19 to plate 9, through the clock and hour-hand to the rotatable contact engaging therewith, to plate a, conductingstrip 30, contact-block 23, conductor 20 to electromagnet S, energizing the same, and by conductor 13, binding-post 14, and conductor 15 back to battery. As the electromagnet is thus energized it will attract arm 30 of the rocking armature causing the conductingstrip to connect the plates, making the lampcircuit and lighting the lamp. As the hourhand continues its movement it will turn the rotatable contact until it passes out of engagement with the conducting-arm, when the current will be broken and one of the nonconducting arms be brought into position occupied by the conducting-arm, as shown to the left in Fig. 1. The hour-hand will then come in contact with the nonconducting arm of the rotatable contact at the right, turning said contact so that one of the conductingarms will be in position to be engaged by the hand when it comes around again to said contact at the time for cutting oil the light, as shown to the right in Fig. 1. When the hourhand again comes into contact at the left or at the figure 5, it will engage with the nonconducting arm thereof, as shown to the left in Fig. 1, turning the rotatable contact so as to put a conducting-arm in a position for use when it is again time for the light to be put on. Passing on the hand reaches the metallic contact at the right, or figure 8, forming connection with the conducting-arm, as shown at the right in Fig. 1, and a new circuit will be established as follows: from battery to binding-post l8, conductor 1?), plate 2, the clock and hour-hand, the rotatable contact at the right, plate 5, strip 31, block 21-, conductor 25, electromagnet 12, conductor 13, binding-post 14c, and conductor 15 back to battery. This will cause the magnet to be energized, attracting arm 37 of the armature, throwing the segment 30 and strip -10 back to normal position, and breaking the circuit between the conducting-strips and turning off the light. hen the lamps or lights are to be turned on at, say, eight oclock in the evening and shut off at, say, five ocloek in the morning, the operation will be the same, except that the rotatable contact at the left will have a non-conducting arm turned in position to be engaged bythe hour-hand, while the contact at the right will have a conducting-arm in line with the hand. The positions of the two contacts will thus be reversed with respect to the conducting and non-conducting arms. It will also in this case be necessary to move the switch so as to bring the contacts 30 and 31, respectively, into contact with the blocks 27 and 28, as seen in dotted lines, so that the first circuit will be through plate and coil instead of through plate 4 and said coil 10, as first described.
