Patented July 21, 1925.
UNITED STATES PATENT OFFICE.
CHARLES F. NORDEN, OF NEW YORK, N. Y., ASSIGNOR TO HENRY HYMAN 8a 00., INQ,
OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
SWITCH WITH TIMING DEVICE. 1
Application filed July 19, 1926. Serial'No. 397,328.
T5 all whom it may concern:
Be it known that I, CHARrlEs F. NoRDnN, a subject of the Republic of Germany, residing at New York city, in the county of New York and State of New York, have invented a new and useful Improvement in Switches with Timing Devices, of which the tollow-' ing is a full, clear, and exact description.\
My invention relates to time switches, the object of the invention being to maintain the current to apparatus controlled by snap switches, push button switches, knife switches, sockets and flash light switches for an adjusted time interval after the switch is turned ofi.
I attain these objects by the mechanism illustrated in the accompanying drawing, in which are 'shown the arrangements of the wiring and mechanism of the switch.
Fig. 1 is a diagrammatic illustration of the invention with the circuit open and the switch off Fig. 2 is a diagrammatic illustration showing the circuit closed; Fig. 3 is a diagrammatic illustration showing the main circuit device turned 01f but with the shuntcircuit through the timing mechanism closed; and F 1g. dis a diagrammatic illustration of the apparatus at the moment that the timing mechanism is releasing the time circuit device.
Similar numerals refer'to similar parts throughout the several views.
The-circuit closing device 01 main switch for the main circuit has a carrier or pin 2 arranged to contact with a second circuit closing device or supplemental element 3 and move it against the pressure of spring 4 intoclosed position as the main switch is closed,-a catch or link 5 on the end of a thermostatic spring 6 engaging the end of the supplemental element 3 to hold it in closed'positiony A screw 7 is provided to bend the thermostatic member 6 to adjustthe extent of engagement between thecontacting' faces of member 3 and the hook 5.
A resistance wire 8, preferably of German silver and of a resistance suitable for the cur- 6 and the other connects to the main circuit between the contact 9 and the lamp 10.
.A contact 11 arranged to be engaged by the member 3 when in closed position is connected to the thermostatic member 6.
. and therefore the time the lam When the main switch is closed, the parts are moved from the position of Fig. 1 to that of Fig. 2, the pin 2 moving member 3 into closed position with the hook 5 engag: ing its end. The lighting current now passes through member 1 and contact 9 to the lamp, substantially no current passing through the shunt circuit formed by memher 3, contact 11, spring 6 and resistance wire 8. When the main switchmember is opened, the hook 5 retains the member 3 in its closed position, but now the lighting cur rent may pass through the former shunt circuit to the lamp. This heavier current heats the resistance 8 and the thermostatic spring 6 to cause it to bend to withdraw the hook 5 and release member 3, whereupon spring 4 moves member 3 to open the circuit and extinguish the lamp 10. The spring 6 now cools and returns to its normal position, ready to engage member 3 when the main switch is next closed.
By adjusting the screw 7 the end of the sprin 6 may be shifted to vary the extent to which the hook 5 overlaps the end of the member 8. This serves to vary the time between the opening of the main switch and the release of the supplemental member 3 10 will continue to burn after the mam switch is opened.
I claim:
1. In a thermostatically-controlled time switch, a main circuit, a pivoted main switch for opening and closing a break in said main circuit, a supplemental pivoted switch having its plane of motion parallel to said main 'switch and having a bias to open position, means to move said supplemental switch to closed jposition when the main switch is closed, a thermostatic latch member comprising a curved sheet netal spring fastened at one end and havlng 'a. hook at the opposite end adapted to engage and hold the supplemental switch 1n closed position, said sprlng extending in the plane of motion of-said supplemental swltch, and a shunt circuit having a part arranged to heat-said latch member to cause it to bend to release its hook from on agement wlth said supplemental switch w en said mam switch is open.
2. In a thermostatically-controlled time switch, a main circuit, a pivoted main switch for opening and closing a. break nsaaeoe said latch member to cause it to bend to release its hook from engagement with said 15 supplemental switch when said main switch I is open, and means to adjust the position of said hook 'in relation to said supplemental switch to regulate the time of operation of the shunt circuit before the supplemental '20 switch is released.
Signed at New York city, N. Y., this 15th day of July, 1920.
