ANTHONY B. ZIERLEYN, OF GRAND RAPIDS, MICHIGAN ELECTRIC TIME-SWITCH.

T all whom it may concern.-

Be it known that I, Au'rnorn' B. ZiERLEYN, a citizen of the United States, residing at Grand Rn. )ids, in the county of Kent and State of It chi an, have invented a new and useful Electric limo-Swi tch, of which the following is o specification.

This invention relates to electric timoswitches, and has for its principal object to provide a means for automaticolly'connectmg-sad disconnect-in an electric circuit so that the circuit may s closed or broken for any desired length of time,

A further ob ect of the invention is to provide a. timing device of this character in which the time of closing the circuit and the time of openingthocircuit may be I indepondcntl of each other. i

provide an electric time-switch of simplo and inexpensive construction and which may be connected at comonrativelysmall cost to an ordinary clock-tram.

With thesoand other objects in view, as

r o clock-train includes a coimon-puuon 15 of equal size, said gears being loosely mounted on orbors 16 and 17, respectively, 'cnd those srbors are rmidcd at a point n front of the clock-dial .wilh knobs 19, by wln'ch they may be turned for the purpose of adjusting the time of o ation of the switch mechanism, Each or 1 comics o small gointer 20, thatri's qmovableovcr s. d al, there sing two dials 21,0118. 22 ongto indicate the time set for closing th circuit and the other to indicot the-time se fl ior ope the cir-' curt, and these are adjustable independently f The core 14' aiid "15ers each provided with into hubs 24, oarrjing timin -.c'ams 25 of the t f eordin V yam loyodin a. arm-trains,

Bearing against the 24 are thaupper bifurcated ends of lovers and 3 1, pivoted in suitable brackctsBZ, and the lower ends of which serve to control the movement of the circuitclosing device. The upper ends of these arms refereed into 'ment with the hubs 24 by means of springs 3, and as soon as one of f the shonlders of one of the timing-cams come 0 osito one of the In 26 the timing-com 81 :5 hub'wiil more out sard under the influonce at s 33, and the cimuit-controiling lover w be swung on its, pivot for the urpose of releasing one of the circuit-contt-o ing members. At a central point under the' clock-trek: is arranged a motcllic'standsrd 36 carrying a pair of slightly-spaced metallic plates 37, arranged for the reception of the opposite ends of a. pair of switch- blades 39 and 40, and when both blades are engaged withthc plate 37 the lighting or other circuit is closed, and when either is disconnected the circuit is open.

The switch-blade 39 is carried by. a block 41 formed of porcelain or other material, and tho rear end of the blade is connected mechsnicolly and electrically to a. stem 42,that

lis arranged to slide withhi sv recess formed be- 13, which intermeshes with two gears 14 and ofeach other mjchthe some manner as an v ordinary elarmoficlianism 13 set, V V A still fun or object of the invontionis'to reduced portion of thestem is surrounded by a helical compressiomspring 50, hearing at one end ainst the collar 47 and at the oposite em? against a lug 51, carried by the ower plate 44 and provided with an opening for the passage of the reduced portion of the stem. This spring tends normally to move the stem outward from the position shown in Fig. l, and thus pull the switch-blade 39 from engagement with the plates 37.

The switchfblade 39 is held from 'rotative movement by a pair offlan cs 53, (see Fig. 2,) formed integral with the ase l() and en- "aging the ends of the blades which project be end the bloek'41; The block 41 is provided with a vertically-dis osed opening 54, in which is arranged a he ical compressionspring 55, held in place by upper and lower plates 56, secured to the block. -These plates are provided with openings for the passage of a verticaly-movable rod 58, car rying at its upper en a catch 59 beveled on one face ,and provided with an abrupt vertical shoulder designed to en age with the clock-controlled lever 31, an when so engaged the lever will hold the switclrblade 39 in engagement with the plates 37 but when lever 31 is moved at the end of a predetermined period qf time to one side of the catch 59 the spring 50 will withdraw the blade 39 from engagement with the plates 37 for the purpose of breaking the circuit. The blade 40 is alsg' mounted in a block 41, which carries a spring-pressed catch 59, of a construction similar to the catch 59, and the stem 42', attached to the blade 40, is acted upon by a spring 50', which tendsto move the blade 40 into enga ement 'with the catch 59. The upper cm of the stem is provided with a knob 48 to permit manual adjustment of the position of the blade 40. The catch 5!) is cngaged by the lever 30 and held by said levar with the blade 40 in the position shown in Fig. l--tl|at is to say, out of contact with the plates 37. The stem 42' is guided between two plates 43 and 44; the lower plate 44 carrying a binding-screw 45 for connection to a circuit-wire 2:.

The normal position of the parts is shown in Figs. 1 and 3, with the blade 40 out of engagement with the plates 37 and the blade 39 engaging said plates 37, the circuit being broken. The pointers 20, carricd by the arbors 16 and 17, are then ad'nstcd to time the closing of the circuit ad the subsequent opening of the circuit, and at the proper time lever 30 will be released and forced to move by its spring from engagement with the catch 59', whereupon the spring 50 will act to force the blade 40 into engagement with the plates 37, thus completing a circuit from line so through binding-screw 45', plates 44 43, stem 42', blade 40, plates 37, blade 39, stem 42, plates 43 44, binding-screw 45, and circult-wire .c. The circuitwill then be closed until the gear 15 in rotating carries its cam to a position to release the lever 31, whereupon said lever is forced by its spr'n :g from enga gement with tlie catch 59 and spring 50 imme diately withdraws the blade 39 from engagement with the plates 37, breaking the circuit.

It will be seen that the time of closing the circuit and the time of opening the circuit may be independentl adjusted and the curcent may be opt on or an desired length of time, this being of especial value in many cases where it is desired to avoid waste of currentas, for instance, in the lighting of a show-window darn: g a portion of the evening or the lighting of a store alter the closing hour, so that a light may be kept burning throughout the night and extinguished early in the morning.
