AUTOMATIC TIME SWITCH.
APPLICATION FILED MAR.16, 1909.
Patented Mar.8,1910.
"ofwhich thefollowing is a unrrn snares PATENT OFF CE.-
PAUL J. STUPARICH, 03: SAN FRANCISCO, GALIFOBNI'AQ To all ibhomit concern: Be it known t t I, PAUL J. Sroranrfin,
citizen of the United States, residing in. the
city and county oi San Francisco and State of California, have invented new and useful Improvements in Automatic TimeSwitches,
specification. My invention relates to a device for automaticall operating an electrical switch after the apse of a predetermined interval of time. I r
In hotels and apartment houses it is a common source of grievance and expense for the landlord to discover in the morning that guests or others coming in late at night have turned on the light in the hallwa and after passing up the stairs' have faile to put out the light.
The object of this inventionis to provide a simple, practical device in the form of an automatic time switch which willnot interfere with theproper lighting of'the lamp,
but aftenthe lapse of five minutes or so, or such other tiine as it is desired to have the light burn, the light will be extinguished.
The invention consists of the parts and the. construction and combination -.of parts as hereinafter .more fully described and claimed, having reference to the accompanying drawings, in which- Fi ure 1 is a side elevation of the time SWltdll. Fig. 2 is a plan view of the same. Fig. 3 is a section through the gear casing showing the gears for operating the switch. F 4 is a diagrammatic representation of the system.
A is an actuating wheel of any suitable description, and having anydesired number of arms. As here shown, this wheel has four arms each carrying a roller, two of these rollersj2 which are opposed to each other extending to one side oi. the wheel, andthe other rollers 3 extending in the opposite direction. This wheel is mounted on a shafts which is revolved slowly by any appropriate"means, so that when the wheel -1S setin motion it will take a predetermined interval of time, say one minute, or five minutes, as the case may be, for an arm to revolve through an arc of 90; the rollers 23 acting alternately in therevolution of the wheel on respective push-buttons l-5 of a three-point switch 6. Each push-button is disposed beneath a spring plate 1 so that as a roller comes down and strikes a plate it will slide over the latter, pushing the plate any the switch 21 is connected with 'as shown at 22,
auroisnrrc 'rrnE-swzrcrr.

in and operating theppush -button. Thesenown in the art, so that-as one button'is puslgzdzin, the other is automatically ushed out. It is also designed that each buttons, and either of them, when pushed in will, put out the light which is to be controlled, all as will be shortly described.
The wheel is revolved intermittently by appropriate means. As vhere shown, the shaft ii: is jourualed in the casing 8, and this shaft carries :1 M9 engaging a worm 10 on a shaft 11.3. I heft llcarries a large worm 12 which engages a small worm Pinion 13 on a shaft 14'. ha-ft 14 carries'a large gear 15 meshing a small worm 16 of the motor shaft 17; 18 being the. motor.: By this arrangement of gears and shafting,-the Wheel Avmay be made to revolve as -slowly as desired, although. e motor may be run at the rate of 1800 to 2000 R. P. M.
Referring to Fig; 4, the lights to be controlled are represented at 20, these lights being arranged inparallel, and connected, with the line circuit with'the motor 18. 6 is a three-pointswitch operated from the motor, andf21 is a three-point switch arranged in the hallway, or other place,for controlling the lights 20. One member of while the two points of, the, switch 21 are indepen ently connected by the wires 23-24 with two corresponding points of the switch 6.
' In operation, with the switches'6 and 2 1 standing in the p osition shown, the current will pass to the ights and through the motor, and the lights will stay lighted' until' such time as one of the rollers 2 or 3comes 1n contact with its res ective spring 7 and pushes 1n correspon" Ing button so .as to these;
the lights, op 'osit-e put out the lights: Pushing in o-ne ofthev 4 buttons 4 or 5 has the same effect as would throwing the switch arm of switch 6, diagrammatically repre entedin .Fig."4, from it is desired to light the contact 25 to the contact 26, and ob--,
button l: or 5 and puts out the light, or until I the light is otherwise tufnedofi' by reversing the switch 21.
Suitabie switch connections v( oot, necessary here to be shown) may be employed by Which the motor may be cut out at, any time; as Where it is desired to have the lights continue to burn for any extended ing in opposite directions and adapted to operate said switch members on the rotation of the Wheel, a shaft upon which the Wheel is carried, a motor shaft, and a train of gearing between the motor shaft and the shaft of said Wheel 2.. An automatic time switch comprising a operate said switch members on the yo a me pair of cooperating switc 1 members having radially extending; arms, a, of said arms having roller contacts e ing in opposite directions and adaptc.

In testimony whereof I have he my hand in presence of two subs messes.
