Jan. 2, 1968 B. LESTER CIGARETTE DISPENSER AND IGNITER Filed July 7, 1965 FIGS United States Patent Ofifice 3,361,894 CIGARETTE DISPENSER AND IGNITER Borislav Lester, Temora, New South Wales, Australia, assignor of forty-nine percent to George Stimson, Temora, New South Wales, Australia Filed July 7, 1965, Ser. No. 470,085 2 Claims. (Cl. 219-261) ABSTRACT OF THE DISCLOSURE In a combined cigarette dispenser and igniter the cigarette is moved when desired to an igniting position in which it is held between a suction device and an ignition coil, the latter of which advances gently towards the end of the cigarette by thermal expansion of a wire included in the ignition circuit. A time delay device cuts off the ignition circuit and the suction and the ignited cigarette is then moved to a delivery position.
This invention relates to a cigarette dispenser and igniter, particularly one for use in automotive vehicles.
One form of cigarette lighter in use in automotive vehicles includes a removable element in the dashboard which is pressed in to energise an electric element in it or in part in contact with it to bring the element or a portion of the element up to ignition temperature so that when the element is removed and it or that portion of it placed at the end of a cigarette, same is ignited. Another type of cigarette lighter is of the type where a cigarette is inserted into a recess which is electrically heated. In both these constructions considerable driver distraction takes place and it necessitates the use of one of the drivers hands for some seconds. Furthermore, there is the general inconvenience of having to remove a cigarette from the package or holder. Such constructions moreover do not provide suction means to draw the cigarette which may make it difiicult to ignite the latter.
The present invention relates to an improved but already known type of cigarette dispenser which overcomes the aforementioned disadvantages and makes provision for cigarette dispensing by providing a cigarette storage magazine and cigarette dispensing means adapted to deliver successively and singly as required cigarettes to ignition means wherein one end of the cigarette is located adjacent the ignition means and the other end adjacent suction means, the ignition means and suction means being operable upon the operation of a mechanism for the insertion of a cigarette therebetween, there being a timing device arranged to cause disconnection of the current supply to the ignition means and transfer of the cigarette to a delivery position.
The present invention provides a cigarette dispenser of the improved type hereinbefore defined including an electrically heated wire adapted by its thermal expansion to permit movement of said igniting means towards the cigarette, and by its contraction to move said igniting means away from the cigarette, and wherein said timing device includes thermally responsive means arranged to interrupt the fioW of current to said wire, said igniting means and an electrically actuated means for maintaining a support for said cigarette in a cigarette ignition position and thus permitting said lighted cigarette to be trans ported by said support to a cigarette removal position.
The invention further comprises a cigarette dispenser of the improved type hereinbefore specified, including a length of electrically heated wire having high thermal extension properties which has one of its ends fixed in an insulated manner to the dispenser frame and its other end attached to a spring biased and pivotally mounted arm which supports the cigarette ignition means, a sup- 3,361,894 Patented Jan. 2, 1968 port for said cigarette for holding it in an ignition position and transferring it to a removal position, an electromagnetic coil with a sliding core which is connected by linkage to said cigarette support, a set of contacts engageable by the movement of said cigarette support into a cigarette selecting position and through which electric current passes to said coil, to said ignition means, to said extensible wire and to a thermally operated circuit breaker.
Preferably the relay or timing device also disconnects the suction when the ignition means is removed.
A preferred embodiment of the present invention will now be described by way of example with reference to the accompanying drawings, in which:
FIGURE 1 is a front perspective view of a cigarette dispenser and igniter made in accordance with the present invention.
FIGURE 2 is a rear elevation of the device illustrated in FIGURE 1,
FIGURE 3 is a sectional 3-3 of FIGURE 2,
FIGURE 4 is a sectional end view along the section line 3-3 of FIGURE 2 showing the parts in their cigarette dispensing positions and FIGURE 5 is a wiring diagram for the dispenser illustrated in FIGURE 1.
An elongated normally vertical cigarette receptacle 10 is provided at its lower end with a metering device including a pivotted arcuate portion 11 in which the lower most cigarette 12 will rest and which is rotatable about an axis so as to discharge that cigarette 12 whilst preventing the cigarette 13 immediately above from falling onto said arcuate portion 11. When it is returned to its initial position it receives the next cigarette 13 and so on. A slide 14 attached to the receptacle and adapted for arcuate movements about its support 141 is provided. In a delivery position it receives the cigarette 12 which rolls to where the slide 14 terminates in spaced arms (or cradle) 15 which carry the cigarette 12 during the lighting operation and support it at the completion of such operation before it is removed.
There is provided a supporting member 16 secured to a frame 17 which carries the cigarette receptacle 10. The supporting member 16 carries an electromagnetic coil 18 provided with a sliding plunger 181, the said plunger is connected to the member 14 by a linkage 142 with a pivot 143 and two universal joints 144 and when the coil 13 is energised, the plunger 181 withdraws into the coil 18 and through the linkage holds the slide 14 in its lowermost and delivering position, which is also the ignition position for the cigarette 12.
At one end of the receptacle 10 and within frame 17 there is provided ignition means 19, which is electrically heated and supported by a lever 31 pivotally mounted on the receptacle 10, Whilst at the other end there is provided adjacent the frame 17 a chamber 20 including a filter (not shown) which is in communication through a control valve 21 to a vacuum system which on an automotive vehicle is desirably the engine manifold. This vacuum system serves to draw air through the cigarette 12 when ignited by the ignition means 19. The chamber 20 has an aperture 191 which is located axially with respect to the adjacent end of the cigarette 12 when it is positioned in the ignition position in the cradle 15.
The slide 14 is coupled through a linkage 23 to the portion 11. Arcuate movements of the shaft 141 for supporting the slide 14, to which the linkage 23 is connected, transmits arcuate movements to the shaft which supports the portion 11 to which a further part of the linkage 23 is connected.
The slide 14 is spring loaded towards its uppermost position and the linkage 23 operates a rotary and spring end view along section line loaded valve 21 to open and close the vacuum line 24 as the slide 14 moves between its lower and uppermost positions respectively.
When the cradle and slide 14 are actuated by hand to deliver a cigarette, movable and fixed contacts 25 and 26 respectively are brought together which permits an electric current to pass through a thermal relay 27 to the aforementioned electromagnetic coil 18 and to the ignition means 1%. The current to the ignition means 19 also passes through a resistance wire 28 (in series or parallel with it) which it heats and in so doing allows it to expand. One end of the resistance wire 28 is fixed to the receptacle 10 in an insulated manner at 29 and the other end is attached to the arm of the lever 31 which is pivotally mounted on the receptacle 14). The lever 31 is connected to one side of its pivot to a spring 32 which urges the coil 19 towards the chamber 20 and to the other side of its pivot to the resistance wire so that as the resistance wire 28 is heated and expands the spring 32 is permitted to pull the lever 31 so as to move the ignition means 19 which comprises a flat spiral coil of resistance wire mounted on the lower end of said lever 31 towards the other end of the cradle 15, i.e. the end where the suction aperture is located. A steady contact (after an initial warming up period) with the cigarette 12 is thus maintained by gently engaging the ends of the cigarette between the ignition means 19 and the suction aperture. The engagement is progressive as the wire 28 expands and adjusts automatically for minor variations in cigarette length. By the time the relay 27 terminates the ignition operation the burning of the cigarette at a rate exceeding that of movement of the ignition coil releases the cigarette from engagement therewith. The amplitude of movement of the filament is constant, but the stationary position of the filament is adjustable, which in itself alters the extreme position of the filament towards the cigarette at the time when the heated wire is fully expanded. When properly adjusted for a particular length of cigarette, the filament, when activated, will exert slight pressure on the cigarette, moving it until it stops against the suction orifice. The heated filament will continue moving towards its extreme position, but at a slower rate than the burning rate of the cigarette, therefore releasing the cigarette from any tension, and allowing free discharge of the cigarette into the delivery position. The adjustment of the suction box is therefore only a supplementary adjusting means for very short cigarettes.
The thermal relay 27 terminates the current supply to the ignition means 19 and the electromagnet 18 after a predetermined time interval thus permitting the plunger of the electromagnetic coil 18 to release the member 14 to return to its normal position under its spring biasing in which position it presents the cigarette 12 lit and ready for removal. When the cradle 15 returns to this position it closes the rotary vacuum valve 21 through the linkage 23.
A release mechanism (not shown) may be provided to prevent delivery of a further cigarette when it is desired to relight a cigarette by placing it on the cradle and bringing it into contact with the ignition 19 means and suction.
Means (not shown) may be provided to vary the initial spacing between the ignition means 19 and the suction aperture so as to accommodate varying lengths of cigarettes. This may take the form of an adjustment connected to the ignition means 19 or a sliding tube journalled in the aperture and provided with holes or slots which are always located in the chamber or in communication therewith so as to maintain suction at the end of the tube in all its positions of adjustment. For this effect the tube may have an inclined slide at its end so as to always displace the cigarette towards the ignition means. Desirably, this slide merges with the respective end Wall of the cigarette holder.
The cigarette receptacle may be proportioned so as to receive a disposable package containing cigarettes to obviate the necessity of loading the receptacle by dispensing direct from the package.
The assembly may be covered by any suitable cover plate so as to blend in with a vehicle dashboard or the like. Desirably such a cover incorporated visual means to reveal the contents of the dispenser.
The control of the dispening of cigarettes may be carried out by a remote control, by an electromagnetic arrangement using a contact-0r or alternatively by direct manual mechanical control as illustrated in this preferred embodiment, the contacts 25 and 26 being closed manually by depressing the member 14 and the rest of the cycle being automatic and being terminated by the action of the thermal relay 27.
