APPARATUS FOR AUTOMATIC LIGHTING OF GAS-JETS AND THEIR EXTINCTION AFTER A PREDETERMINED TIME.
Specification of Letters Patent.
Patented June 18, 1907.
Application filed November 11, 1904;. Serial No. 232,323,
To (LU 1071,0111 it may concern:
Be it known that I, FREDRIK Tns'rou, manufacturer, a subject of Sweden, residing at 49 Surbennusgatan, Stockholm, Sweden, have invented new and useful Improvements in Apparatus for Automatic Lighting of Gas- Jets and Their Extinction After a Predetermined Time, of which the following is a specification.
This invention relates to an automatic apparatus resembling those for electric stairlighting, but designed for gas-lighting and operating in such a manner that one or more gas-jets can be lighted for instance by pressswitch in the illuminating circuit.
ing on a button and extinguished after the elapse of a predetermined time.
The automatic devices for electric stairlighting chiefly consist of an electromagnetarmature connected partly with a clockwork or other check-mechanism (controlling the duration of its motion) and partly with a I l On closing the circuit of the electromagnet the armature will be set into motion and the position of the switch changed so as to close the illuminating circuit and light the lamps, whereupon the armature gradually returns to its position of rest and, on reaching this, returns the switch into such a position as to break the illuminating circuit and cause the extinction of the lamps. This contrivance, according to the present invention, is also applicable to gas-lighting, if the cocks of the gas-burners be arranged to turn on or shut ofi the gas by means of an electric current.
The present invention relates to a combination of such gas-burners with the automatic stair-lighting device just mentioned.
The invention is illustrated in the accompanying drawing in which verse section.
a is the electromagnet, b, b are its poles, c is an oscillating armature carrying a pawl cl actuating a ratchet e which is combined with a suitable clock-work or cl'ieck-mechanisin as shown in Fig. 2-.
f is a spring operating for returning the armature to its position of rest (indicated by full lines). The armature is connected with a rod 01 with two arms 0, r situated on each side of a lever Z which is movable over two contacts is, m in their respective circuits for actuating the gas-cocks.
n is an electric conduit between the gascocks and the lever Z. Contact mis in the circuit for turning on the gas, while contact 7r: belongs to the circuit for shutting off the flow of gas. The conduit 11- and lever Z, complete the circuits.
On pressing the button a, the electromagnet becomes magnetic and its armature being turned into the position shown by dotted lines in the figure will lift the rod i thus causing the lower arm 0 of the latter to swing the lever Z from the position indicated by full lines. The lever in its motion first passes the contact 7c and subsequently occupies the position indicated in the figure by dotted lines, against the contact m, in which position it closes the circuit for turning on the gas to the burners, the outl'lowing gas being lighted by means of a pilotjet, for instance or any other suitable means. As the clockwork rotates the ratchet c the spring is permitted to gradually return the armature to original position, the rod i meantime descending. TI hen the latter has reached its lowest position, the upper arm 1* strikes the lever l and swings it back to its original position. The circuit for turning on the gas is hereby first broken and that for closing the gas supply is subsequently closed (through the contact 1:) so that the gas is put out.
1. In a contact controlling device the combination of the stationary contacts, of an electromagnet, an oscillating armature, an oscillating lever connected to the armature and arranged to move over the contacts and check mechanism for controlling the return movement of the armature.
2. In a contact controlling device the com:
bination of the stationary contacts, an oscillatmg lever arranged to move over the contacts, an clectromagnet, an oscillating arma- I lgure 1 is an elevation, and Fig. 2 1s a transture, a spring for returning the armature to normal position, a connection from said armature to the oscillating lever for oscillating said lover, a ratchet, a pawl on the armature engaging with said ratchet and check mechanism actuating the ratchet for controlling the return movement of the armature.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
