ELECTRIC TIME-SWITCH.

Specification of Letters Pat ent.

TPatented Jan. 7, 1908 Application filed March 11. 1907. Serial No. 361.764:-

' whom it may concern."

known that I, 'FnA'isK W. BROOK, of the United States, residing at a cam, in the county of Sanganion and oflllinois, have invented certain new and useful Improvements in Electric Time- Switches, ofwhich the following is a full, clear, and description, reference being had to the accompanying drawings, forming a part hereof. v My invention has relation. toimprovennents in electric timeswitches; and it con- S in. the novel construction of switch more lolly forth in the specification and j pointed out in the claims. the drawings, Figure 1 is a front eleu. of my invention showing the elecnits open; Fig. 2 is a similar view the circuits closed; Fig. 3 is a vertical transverse section on'the line 3-3 of l l and Fig. is an enlarged elevational detail of the latch and pawl for breaking or closii'ig the circuit, showing the rear of the lock and alarm key thereof for tripping the ohject of my invention is to provide 'nooperated sun'tch for turning store on and off at stated intervals, special ,tion being hadfor simplicity of operaanu urability of the parts. In detail tion may be described as follows: to the drawings, C, represent cl placed in contiguousrelation to a ending number of latches which rew operating weightsby which. the e operated. Adjacent to the a post 3: to which is pivoted near r, a vertically oscillating latch 2 end "caches to the head 3 of the to alarm mechanism of the opposite end terminating in a en ages and locks in elevated tion gravity pawl or arm passes through a loop or lb weight W is suspended. is connected the lower end of deli passes over a pulley 8, the two ends a, a which are pivoted switch-

levers

similar switch lever

9, 9, each circuit comprising a Wire w, arm 10, switch lever 9, a supporting arm 11 for the switch lever, a connectingiwire section a a second supporting arm 11, a switch lever 9, a contact arm 10 and wire w. In connection with the clock C is a similar arrangement of latch 2, post 1, hook 4,

pawl 5, and cord 7 with weight W, cord connected with the 9, to closed position, thus closing the circuits and automatically turning on the lights; The lights remain burning until such time as it may be necessary to extinguish them. To eflect this automatically the merchant sets the clock C to a definite hour, at which time the alarm goes oil, the head of the alarm key tripping the latch 5, whereupon the release of the weight W draws on the cord ends a a (dotted position 'Fig. 2), thereby oscillating the switch-levers 9 9 to open position and breaking the circuits.

Of course the cords 7, 7 may have any number of cord ends a, a, to controlany number of circuits, one clock being always set to turn'on the lights by closing the circults, and the other by breaking the circuits.

to extinguish the lights Having described my invention, what I claim is:

In combination with an electric circuit of said which the alarm has been set and release the Weight whereby the latter puhing on the cord oscillates the switch lever to closed position, and a second clock cooperating "with a simiiar latch, pew], weight and cord secured to the second switch-lever,

.vherehy at a predetermined hour the release of the second Wel ht 1s efiected, and. the pnlhng on the cord t ereof osclllates the second switchiever to open osition end the circuit is broken, substantially as set forth. In testimony whereof I affix my signature, in presence of two witnesses.
