UNITED STATES CHARLES H. CUNO, 0F MERIDEN, CONN ECTICUT, ASSIGNOR TO THE CUNO ENGL- NEERING CORPORATION, OF MERIDEN, CONNECTICUT, A CORPORATION OF CON- NECTICUT.
ELECTRIC CIGAR LIGHTER AND THE LIKE.
Application filed July 19,.1924. Serial No. 726,934.
To all whomct may concern: 5
Be it known that I, CHARLES H. CUNO, a citizen of the United States of America, residing at Meriden, county of New Haven, State of Gonnecticuhhave invented a new and useful Electric Cigar Lighter and the like, of which the following is a specification. My invention relates particularly tofeatures involving a manually operable switch. The main object is to provide a simple, inexpensive but reliable construction in which the circuit is normally opened but which is adapted to be closed by pressure on a push button.
Another object is to provide a construction ofthis character which is adapted to interchangeably carry a heater unit.- An other object is to provide a construction of standard-type the parts of which can be readily assembled in their proper relation.
Fig. 1 is a longitudinal cross sectional view of a construction embodying one form of the improvements of my invention on a scale somewhat larger than would be necessary for ordinary commercial use.
Fig. 2 is a detail side view showing the unassembled parts on a smaller scale.
Fig. 3 is a transverse sectional view on the plane of the line 3-3 of Fig. 1. v
The casing 5 is preferably of tubular form, for instance, of metal adapted to contain the switch and hold the heater unit 6. It is also preferably adapted to support a guard or shield 7. The cable or cord 8 usually consists of two conductors or insulated wires.
The heater unit preferably has two pins or projections-9 adapted to interlock with bayonet slots 10 in the outer end of the tubular socket member 5. This heater member has preferably a body 11 formed of insulating material'adapted to suitably support a heater wire 12. One end of this wire is secured to a central contact button 13 and the other to the outer sleeve or ring 14.
In the particular form shown herein the switch member proper has a U-shaped frame or yoke 15, to one endof which is soldered or otherwise suitably secured one of the circuit wires 16. This frame 15 is secured to the tubular casing in a suitable manner, for instance, by a screw 17 which holds the parts together. -The other end of the frame 15 carries one or more spring pressed plungers 18 which press against the end ofthe heater .unit to yieldingly hold it with its pinsin place in the slots in the tubular casing.
The spring contact arm 19 is secured to the frame 15 though insulated from the frame by washers 21. The conductor 22 is secured to this rivet 20 as shown in Fig. 1. The outer end 23 of the arm 19 is bent over and adapted to engage the center contact 13 of the heater when the button 24 is pressed. The button is insulated from the arm 19, for instance, by the insulating strip 25 and washer 26. An insulating guard sleeve or collar 27 may be provided around the outer end of the wire 22.
\Vhen the button switch is closed the circuit is complete through wire 16 to the yoke or frame 15 thence through screw 17 to casing 5, thence to the terminal collar. 14 of the heater unit, through the heating coil back to the contact 13, thence through the arm 19 t0 the conductor-22. When the button 24 is mechanically by a rivet 20 al-' released the spring arm 19 automatically opens the circuit. When the plungers 18 are of metal the circuitmay also pass from them .to the end of the ring 1 4.
It will be obvious that the heater unit may be attached and detached as desired and that the shield 7 when used may be ap lied in any suitable manner, for instance as s own in the Cuno Patent #1,346,368. Itshould also be understood that this switch and heater unit may be used either with or without a reel as shown in Cuno Patents 1,208,504 or 1,378,013.
It will also be obvious that any ordinary electric lamp bulb can be readily substituted for the heater unit. a
The frame 15 with the pressure plungers and switch contact arm. made u and handled as a unit adapted to be inserte in any casing. It'will also be noted that the frame and contacts can be readily removed from the casing'as a unit for the purpose of inspection.
