TIME-S WITCH.

Specification of Letters Patent.

Patented Jan. 3, 1911.

To all whom it may concern:

Be it. known that l, A mnon \V. Kolnun, a citizen of the United States, residing at Richmond, in the county of l-lenrico and State of, Virginia, have invented certain new and useful improvements in Time-Switches,

of whiclrthe following a. specification,

reference being had to the accompanying drawings.

This invention relates to improvements in time switches, and more particularly a time controlled electrical cut out adapted for use in stores and buildings for extinguishing one or more. electric lamps or series of lamps at.- a predetermined time, although the device may be employed for other purposes.

' The object of the invention is to provide an improved cut-out or switch of simple and practical construction which may be conyenientlyset and when set will be entirely automatic in operation.

- \Vitli the. above andjother objects'in view,

the invention consists of the novel features a of construction and the combination and arrangement of parts hereinafter fully de scribed and claimed and illustrated in the accompanying drawings, in which-- .Figure'l is a front/eievation'of my: im-

7 proved time switch, the electric-circuit being diagrammatically illustrated." Fig. 2 is a de-v tail sectic' nal View taken on the plane indicated by "the line 2+2 in Fig. l,and-'Figs. 3

.J'and tare detail views of parts; Referring moreyparticularly to-the draws "ing,-1 -indicates a-clock dial upon. which my improved Qti me switch'is arranged. This switch is controlled by the hour hand 2 of the clock which carries a trip pin 3, V which is' fa'dapted toiengage and actuate acou- -ductorgarm, l, pivotally mounted to rotate I aboilljt the hour;handshaft 5 from which it:

i s' jinsulatejd by means of a sleeve tv. The

"conductor-amid is thus mounted for movei Inent independent of the time"indicating hands ,and'itdsfadapted to be adjusted to break the electric circuit-at a predetermined -A cont-actbloclti -is arranged for move;-

Im'entbetween the concentric stationary nonconductin rings 8 which are-secllredupon thetacc o .the-dialin"any well known man insulating material; The rings Bfare'of angu- 'lart os'iss ecti'onali:forniltopifoyide'the track the opposite edges of the contact block 7. It will be noted from reference to Fig. 2 of the drawing that the flanges 9 of these rings are slightly inclined, the flange of the inner ring being disposed nearest the face of the clock dial. The upper and lower surfaces of the contact block 7 when in position between the flanges 9 are therefore also inclined toward the center of the dial. The block 7 is formed 'in two sections, one of which is composed of copper or other electric conducting material, and the other of rubber or any well known insulation as indicated at 7'. These block sections may be cemented or otherwise secured together, and the metallic section is provided with a suitable finger piece as shown at Fig. 3 whereby the block may beeasily moved between the concentric insulation rings 8, to any desired point of the clock dial, at which time it is desired to break the circuit and extinguish the lights. The end of the arm 4: is then positionedupon the upperinclined surface of the block 7.-

This arm is .sufliciently resilient to cause 'the same to retain its position upon the block 7 in any position of the clock. The sleeve 6 upon which the innerendof the arm 4 is mounted is fitted upon the shaft 5 so as to prevent outwardmovementof the arm toward thegcasing of the dial whereby secure frictional'contact'of tl1e end of the arm, with 'the block 7 after it is released is insured.

After-the block has been properly positioned andthe arm engaged therewith, the circuit is connected, and when the hour hand 2 reaches the t-imeset for extinguishing the flights, the pin 3 carried thereby engages thearm 1 and moves the same from the timing section of the block to .the insulated section 7, thereof, thereby breaking the circult, and the said arm 4 continues tomove withthe hand until itclears the insulated section offthe block and drops 'therefrom upon the noneonducti ng rings s:. .By providing the, insulation .section 7-, in the vent that'the arm 1 should drop back a-gainstthe endof the block," the circuit would Istilllbe disconnectedQ-The conducting wires grand 1210f the circuit are connected-to 'theinner endof theiarinfl, and to'the metallic section of the block :7 respectively; The lamps 13 are includedin the circuittogetherwith a cut out ,switchl. One "or moreoffi-saidswitches may be mounted on a panel, board controlling the fsygitches I "14,. illldaihcitliiing no 15, which is pr'oyided. with a main; switch 16,

an electric circuit 17 containing a meter 18, which is connected to asource of current supply by means oft-he wires 19, which latter may be the usual street line of an electric light company supplying the current to the buildin 1n which the switch is arranged. \Vhile t llS is one manner in which the switch may be connected up and used, it will. be obvious that the invention may be utilized in many other ways and for a great number of different purposes. The circuit wire 17 need not necessarily ass through the casing which incloses the c ock and switch mechanism, when connected in series before switch 16., Furthermore, it will, be readily understood that the wire 12 may be directly con nected'to the circuit wires-17 andthe con' trolling switches 14 and 16 located at a point distant from-the time switch when all lights are simultaneously extinguished.

-ln the use of the invention, as above 'stated, tl1e block. is moved to the desiredpoint and the resilient arm 1- lifted and disposed upon the same. At the proper time, the 'pin 3 engages said. arm and moves the same ofl of the block 7 and breaks the cit cuit and extinguishes t-he lights. 'After the arm movesofl-of the block, the resiliency of the same causes it to engage upon the flanges 9b)? the non-conductin rings where by itis disposed below the en of'the pin 3,

thus remaining stationary while the hour hand 2 continues its-movement. The'arm 4 is also, providedwith a finger piece similar to that-carried by the block .-7 whereby, it'may be readily lifted and engaged upon the.-con-' tact' member. stood that when the block" and arm 4' have "been properl adjusted, th e switches 1 and '16 are close so that theelectric circuit is connected. It will beunderstood that in practice the handles on the block 7 and on the conducting arm 4 will be madeof insu latingmateriai so as to render it safe tohandle the "device. It will also be. understood-that should it become necessary, suitable means-will be-provided to hold the construction and 0 block 7 the various parts, itwill be understood that It will of course be under--' against movement between the.

the device is susceptible of many minor shaft, a conducting block movable between the said guide rings and pro ecting from the outer faces thereof, hands on the hand shaft, one of the said hands being provided with a pin which projects toward the dial and a conducting arm' pivotally mounted on the hand shaft and for disposition with its .outer end on the said' conducting block to dispose the said conducting arm in the path of the said pin of the said hand, the said conducting arm being a spring arm and adapted thereby when moved from the said conductin block to move out of the path of the said pin.

.2. In apparatus of the class described in' combination with a clock dial having a pair of concentrically disposed non-conducting rings on the outer side thereof, spaced apart and provided on their opposing sides with flanges, a conducting block mounted for movement between the said guide rings and having grooves in its sides engaged by thefianges thereof, said conducting block projecting beyondthe outer sides of said guide rings and being also provided with a noneonducting section at one end thereof, a hand shaft projecting from the dial, hands on the hand shaft, one of thesaid hands being provided with a pin whiclrprojects toward the Y dial, and a spring conducting arm mounted on the said hand shaft for movement aroundthe dial, and to bear-on the said block, the

said conducting arm when thus'disposed on the block being in the path of the said pin of the said hand, the said conducting arm when moved from the said block dropping upon the inner guide ring, and hence getting out of the path of the said pin'forthe purpose set forth.

In testimony whereof I hereunto aflix my signatnrein the presence of two witnesses. ARTHUR W. KOINER.
