Specification of Letters Patent.

Patented March 31, 1908.

Application filed August 1, 1906. Serial No. 328,688.

To all whom it may concern:

Be it known that l, (mimics E. Avsnr, a citizen ol the United States, and a resident ol" Jersey (ity, .lludson county, New Jersey, have made certain new and useful Improvements in 'lime-Switches, of which the follow-.

ing is :1. full, clear, and exact description, rel.- erel'ice being bad to the accompanying draw ings, Forming part of this specification.

My invention relates to circuit-controlling devices 'l'or electric circuits and the object thereof is to 'irovide a simple and ellicient circnit-controlling device or switch which will operate automatically at a predetermined time to open or close an electric circuit.

A. further object thereof is to provide means for so operating existing types of switches and which will also permit the man-- uni operation 0'! the switch at any time and also the resetting of the same without any interl'erence with the time controlling devices.

A further object thereof is to provide op erating means by which the same apparatus may be employed to open or close the circuit by simply traiisposing the position ol the switch device.

illustrating its constructionand mode ol o 'ieration. l will describe a preferred lorm ol; apparatus embodying my invention which is operated in the manner described to close a circuit at a predetermined time with. the innlerstondmg; that it is not my intention to limit my invention, as delined in the claims, to the details ol' construction shown or to a device operating: to close a circuit.

In the drawings Figure 1 is a view in ele votion and partly in section on the line l'-l l!" l of apparatus embodying my inventioi L is a plan View thereol'; Fig. 3 is a detail vim showing the actiui ting Ii'ic .-.l'iaiiisiii or scale, and Fig. 4 is a similar VlOW on a hu show'inu' me parts in another position.

Similar reference characters are employed to designate like parts in all views.

The eppariittus is supported on a plate l which may he seemed to awall or other support 2 in any suitable manner. A. bracket 3 is attached to the plate l and su 'iports the time actun. lip; mechanism at which as shown may be an nll'irn'i oloclr ol. ordinary construc tion, n rear ehrvation of which is illustrated in l ig'. l. A cam fixed to some rotating element oontrolled-by or actuated with the Prel'erably and shown this cam is secured to the WllHlli'lg our i the alarm which is released to re tote in the direction shown by the arrow in Fig. l at any desired prmletermmed time lor which the alarm is Secured to the plate 1. is a switclrS ol' the push button type. As shown the switch is operated by push buttons 9 and 10, to actuate a switch lever ll to throw a switch blade. 12 into and out of contact with the switch. contacts 14 to open and close the circuit. shown in Fig. 'l the circuit is open. By depressing the button 9 the switch blade will be thrown into engagement with the contacts 14 to close the circuit. By depressing the button 10, which is elevated when the but-' ton S) is depressed, the circuit will be opened and the switch reset. As my invention does not reside in the form of switch employed, and the operation of push button switches is well understood by thoseskilled in the art l deem it unnecessary to describe its construcs tion more in detail.

A lever 18 is pivoted to the switch plate or cover 19 of the switch box 20. Its free end lies directly under the operating suiiace of the cam 5 and is engaged thereby. A spring arm 2.1v is secured to the lever 18 and projects outwardly therefrom with its l'ree end in contact with the top of the pushbutton S). The

outer end ol the lever 18 is provided with a 5 channel or groove which receives the edge of the can]. 5 and with the parts in normal posh tion, that is to say before the operation. of the same, as shown in Fig. 3, the spring arm 21 will be under slight tension holding the parts yie-ldmgly in engagement.

The opcratirw surlace of the cam "5 is formed to give t l0 cam a constantly increasing throw as the camv revolves to operate the apparatus. A stop 22 engages the lever 18 and arrests the movement ol" the mini alter the switch has been. operated, and a similar stop 23 formed on the opposite side of the calinengaires witli the end of the lever 18 when the cam i" prevents the lurther movement of the cam.

With the form ol apparatus shown, the parts being" in the position shown in Fin 1].

when the alarm trainv is released at thotime for which the alarm has been set, the Wlll(l ing arbor-(Swill revolve making a partial revolution. This movement of the arbor-will carry the cam 5 with it depressing the lever 18, spring arm 2! and push button l) to close the switch which will remain closed until the cam 5 is turned back to its reset position and the push button ll) is operated carried by the cam 5 at and 100 t). As will be to open the switch. The resetting of the cam 5 will rewind the spring which actuates the alarm train and the device will be ready for another operation.

The switch inclosing box. 2t) ma be readily removed l'rom the plate t and in order to arrange the mechanism to automatically open instead oi to close a circuit at a predetermined time, it is only necessary to remove the. switch box, reverse the cover plate it) thereon and then replace the switch box in reversed position so that the cam 5 will act uate the push button It) instead ol the button understood this lever might be omitted and'the. cam 5 arranged to directly engage a push button ol" the switch.

.l claimr l. in a time switch, the combination of a time keeping device, a rotating arbor controlled thereby, a cam carried thereby, a push button switch, a lever actuated by said cam to operate a push button of the switch and a spring secured to said lever to furnish a yielding connection between the ram and the lever substantially as set l'orth.

l. in a time switch, the combination ot a time keeping device, a rotating element controlled thereby to operate at a predetermined time, a cam carried thereby, a push button switch, and a lever engaged b v said cam having a spring arm which engages a push button ol" the switch, substantially as set lorth.

3. In atime switch, the combination of a time keeping device having an alarm train arranged to operate at a predetermined time,

a winding arbor t or the alarm, a cam secured thereto, a. )ush button switch, a lever arranged to be actuated by said cam and a spring which furnishes a yielclim connection between. a push button of the SWltGh and said cam.

t. In a time switch, the combination of a time kee ing device, a rotating element controlled t iereby, a cam carried by said element, alever actuated thereby, a push button switch having a button for closing and a button for opening the switch, and a support for said switch upon which the switch mechanism is reversible to bring either one ol" said push buttons into operatn 'e relation with said lever.

3. in a time switch, the combination of a time keeping device, a rotating element controlled thereby to operate at a predetermined time, a push button switch having a button for opening and a button for closing the switch, a cam carried by said rotating element and asupport For said switch upon which the switch mechanism is reversible to bring either one ol said push buttons into operative relation with said cam.

(3. ln a time switch, the combination with the alarm winding arbor of a time clock, of a push button switch, a lever engagirn a push button ot the switch to actuate t 10 same and a cam carried by said winding arbor and directly engaging the switch lever when the arbor is released, substa-ntiall as set forth.
