Specification of Letters Patent;- Ayplicstion filed February 16,1907. Serial No. 357.668.

Patented Nov. 12, 1907.

To all "inborn it may concern: I

Be it known tli: it we, Qua. A. Pnmronnx and Aninun H. YOUNG, both of Chicago, Cook county, Illi- -.'noi s, have invented a newiind useful Time Contlled Circuit-Closing Device, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification ,"in which- Figure 1 is a front elevation, .partly in section of a timecontrolled circuit closing device embodying our invention; Fig; 2 is a vertical section of the -same; 3 is a showing the electricalcircuits; Fig. 4 is a front elevstion of a. modified form of relay; and Fig.

5 is a section of the same taken on the line V- "of Fig.

4, with the contacts Our invention is designed to provide means of simple, convenient and reliable character, for the purpose I .of closing electric circuits at predetermined times; :ind

predetermined times, :of one or more controlling is more particularly designed to provide nzeans of this character which may be usedto gdvantage for the pub pose; of actuating whistles or other 'signals, at certain with this object in'view, our invention consists in the cornbination, with a clock movernent having its hour hand arranged-to-make electrical contact at cerdriven by the clock movement, and having contact devices which cooperate with the contacts controlled by the hour hand to complete an electric circuit. This circuit includes a suitable relny device which controls a woflcingcircuit orfcircuits.

Our invention also consists in the novel construction, arrangement and combination of .parts, all substantinlly as hereinafter described and pointed out in 35- the appended claims: v v

listening to the accompanying drawings, in which we have illustrated one form of'apparatus embodying our invention, the numeral 2 designates a suitable case or closure having a clock dial 3, and containing a clock. movementoi any ordinary character.

4 is the minute hand of the clock carried by the spindle 5, and 6 is the hour hand which is carried by the sleeve 7, said spindle and sleeve being driven through the gear 8 actuated by the usual movement, not shown.

9 is an electrical conductor of circular form which is placed adjacent to the outer edge of the dial 3, and is electrically connected with one side of a circuit supplied battery 10, and including the coils 11 otthe magnets of a relay dence 12. The conductor 9 is connected at intervals by branch con'ductors lB with contact points 14 which project beyond the outer lace oi the dial, and are secured in insulating plugs 15 sorted in openings of the dial. The number and location of the contact points 14 will depend upon the time or times at which the circuit is to be closed. 7 in the draw- -arranged to be engaged by a contact ingsrwe have shown one of these contacts arranged-to be engaged with a contact device 16 carried by the hour hand 6 at 12 oclock, 12:30 o'clock, 1 oclock, 4::30.-

nclock, 5:30 o'clock, 6 o'clock and 7 oclock, respectively. The contact device 16 on the hour hsnd'6 is connected by a conductor 17 with aconductor 18 surrounding the sleeve 7 and engaged by a contact finger 19. The contact finger 19 is electrically connectedby conductors 20 with similar contact fingers .ZI-and 22-.

The finger21 makes electrical contact with a conducting ring 23 carried by a gear wheel 24, and the finger 22 makin contact with a similar ring 25 carried by gear wheel'26. The gear wheel 24 is connected by ineansl sleeve 7, said gear'wheels being arranged tocauso th wheel 24 to make one complete revolution each twentr four hours. The gear wheel 26 is driven by a pinion on the shajt of the gear wheel 24, and is srranged to contact-ring is rovided with a series of contacts 31 of gear wheels 27 and 28 with a gear wheel 29 on the '1 J nuke one complete revolution each sevendeys; The 7 which we designed to be engagedby u contact finger 32. 1 The contact ring 25 carries a contact 83 which is 84. The

two fingers 32 and 34 are connected in series with the reverse side of the battery 1Q by a co'nductoilhS.

The contact rings 23 and their respective gear wheels, as best shown in Fig. 2 The. arrangement of contacts carried by these rings will best understood by reference to Fig. 3 in which the time relations are indicated. Thusit'will be seen v i the ring 23 hascontacts which are arranged to been gaged by the finger 32 at 12 ocloclr noon, 12130 p. 111.; st 1 p. on, at 5:30 rm, 6 p. m., 7 p.i1n.,' 12 o'clock night, 1 oclock a. ni 6 a. m and-7a. m.;- while the ring 25 has a single contact arranged to engnge thefinger 34 at 4:30 p. in. Saturday. Y l

The relay. 12 controls a working circuit'iill in which 1 is placed the actuating or releasing device iorthe whis tle or other alarm to be sounded. Ylhen thp device is operated in connection with apparatus 'Qwhich quires a comparatively heavy current inithe'circuit controlled by the relay, I prefer to employ a relay such as is shown in Figs. 4 nudS. lntliesc figures, 38 designates-the relay magnet, and 39 an armature q rried by a lever 40. The longer arm ofthislcver carries a contact 41 at (nu-h and, and these contacts are arranged to cooperate with contacts 42 whichoro carried by arms '13. 44 is a spring which is cornice-tori to the short arm oi the lever 40. 45 is a screw [or adjusting the tension 02 the spring so that the lever 10 andcontact 41 will be normally held or balanced in the position shown in Fig. 5. When, however, thc circuit is completed in the magnet oils 38, the :irnurturc "10 is nitnmlml which H bringsthe contacts 41 and 42 together. \s'soon3u the circuit is broken in the magnet coils, the spring contacts 31 or 33, the circuit is not completely closed.

- If, however, either of the controlling members is in circuit closing position, a complete circuit is made, and the ,relay magnets are energized to close the working circuit by nieans of the movement of the relay armal5fture-37. 'it will benote'd that the contacts l6, 19, 21

and 22 arein series with eachother, while the contacts 21 and 32 and the contacts 22 and34 are in multiple relation. Therefore, while the circuit must be closed at the point 16 and also at one of the controlling m embers in order to complete the circuit, the circuit at i each controlling member is closed independently of the other controlling member. I i

- In the particular arrangement-illustrated-in the draw- 'ings, :thenlarm or whistle will be sounded each day at of the times indicated on the ntrolling ring 23,

; and: will also be sounded at 4:30 oclbck on It willbe understood that the particular arrangement shown isillustrative merely of one application of the 80 invention, andthat the particular arrangement of the contacts on the dial and on the controlling members,

and the number of controlling members, and the ratio 'of their gears will depend upon the particular the spirit and scope of our invention.

What we claim is: 4 1. Time-controlled circuit closing mechanism comprising a clock, a normally open electric circuit having contnctssrranged to be closed by a hand of the clock at I definite times, and a plurality of controlling members geared to the clock work to rotate in diflerent time pe riods, and contact devices controlled by said members, the contact devices controlled by each member being in series with the contacts controlled by the clock hand, but in multiple with the contacts controlled by the other member or members; substantially as described. 4

2. The combination of aclock movement, a normally open electric circuit having a plurality of contact devices in the pathot movement of a hand or the clock, a cooperating contact device on the hour" hand, in. controlling member geared to the clock movement to make a complete revolution each twenty-tour hours, a second; controlling :mcmber geared to make a complete 'days, and contact devieesoontrolled by each ot'the con rotation each. seven trolling members, the devices controlled by,each member being in series with the contacts controlled by the clock hand; and in multiple with the contacts controlled! the other member; substantially as described: i
