Claims.

Our invention relates to portable cigar and cigarette lighters, and more particularly to portable electrically operated [dry cell-operated] lighters. I

It is the general object of the invention to provide a simple and compact cigar and cigarette lighter which is operated by a battery of small dry cells, and which is capable of functioning even when exposed to high winds, and is free from fumes and odors.

It is a further object of the invention to provide a cigar and cigarette lighter of the type indicated wherein means are provided for positioning and interconnecting a plurality of dry cells in side-by-side relation.

.It .is also an object of the invention to provide a battery-operated lighter in which an electric resistance element heated by the battery current can be withdrawn from the casing for use at a point remote from the latter whereby greater convenience in use is afforded, a cable of suitable length being connected with the resistance element and being normally coiled within the casing.

A .still further object of the invention is to provide a battery-operated lighter wherein the electrical circuit is normally open but is automatically closed upon opening of the cover of the lighter.

Still another object of the invention is the provision of means for keeping the electrical circuit open when the control switch fails to function for any reason.

It is a further object of the invention to provide an improved mounting for an electrical heating unit which .is of more general application and is suitable for use in electrically operated cigar and cigarette lighters, the heating unit and its mounting being united into a separate and separable structural unit whereby the heating coil may be easily and conveniently removed for repair or recompartment by means of a conducting spring placement and the repaired or new unit as easily and conveniently fitted on its support and connected in the electrical circuit.

In the accompanying drawing is shown a preferred embodiment of the invention. In said drawin Fig. 1 is a vertical section through the lighter on an enlarged scale;

Fig. 2 is an end view of the lighter as shown in Fig. 1;

Fig. 3 is a top plan view of the lighter with the cover in the open position;

Fig. 4 represents a fragmentary view in ver tical section;

Fig. 5 is a plan view of the removable bottom wall of the casing; while Figs. 6, '7 and 8 show modified forms for mounting and supporting a'heating unit for convenient detachment.

The casing of the lighter comprises a main'body portion ll] of approximately rectangular cross section to which is pivoted, at H, a cover I2, the latter being normally biased to the open position by a coil spring 43. The cover is held in a closed position against the action of spring 13 by a detent member in :the 'form of a plate is secured upon the inside wall of the casing as .by "means of rivets 15 and provided at its upper end with a cam-faced lug l6 which is arranged 'to pass through registering openings in the casing wall and in the closed cover, as will be readily under stood. The detent is released by means of a finger piece 11 which passes through a suitable opening in the casing wall. For reasons which will appear hereinafter, the bottom wall of the casing is separable from the main "body of the casing itself, and :as shown, is in the form of a plate It provided with a peripheral flange I9 having open-ended slots 20 adapted to receive the stems of screws 21 threaded into suitable openings in the vertical end walls of "the casing It. As will be obvious, upon loosening of the screws '2 I the bottom wall l8, 19 can be removed from the casing to provide access to the interior of the latter. To prevent loss of the screws 2|, their inner ends can be struck down as shown at 22.

The casing is internally constructed to receive a plurality of dry cells; and in the preferred form of the invention, 'the :cells are arranged in at least two columns or files, instead of in the single file arrangement common in flashlights. The dry cells are preferably of the high ampere-hour type providing a potential of about four volts per cell. Each cell 23 has a metallic shell constituting one of its terminals and is provided with an insulating cover 24 of paper or the like. Three cells of this type connected "in series are suflicient to provide the current for operating the resistance element of our lighter over quite a long period of time, and as shown in Fig. 1, two of these'cells may be arranged in co-axia'l relationship. The third cell, shown at '25 is arranged laterally on the two-cell column and preferably in adjacent relation. To this end the interior of the casin is divided into three compartments by the partitions 25 and 21, the compartments being indicated at 28,29 and 30. Two of these cells, as shown, are positioned in the compartment 28 while the cell 25 is located in the compartment 29 and is elec- Extending across both of the compartments 28 and 29 toward the top of the casing I is an insulating plate 33 which forms a stop for the first or upper cell 23 in the compartment 28. The plate is provided with an aperture 34 into which the positive terminal 35 of the saidfirst cell protrudes. The compartment 29 is similarly provided with an insulating stop plate 36 fixed intermediate its ends for limiting the inward movement of the cell 25. A contact member 31 is secured to the plate 36 in position to engage the metallic wall or negative terminal of the cell 25.

The third compartment 30 is provided at its upper end with a support 38 adapted to receive an electric resistance element which is indicated generally at 33. This element includes a stem portion 40 of sufficient length to be grasped conveniently with the fingers, and is of enlarged diameter at its upper end as shown at 4| to provide a shoulder which is adapted to engage the support 38. Within the member 4| there is arranged a high resistance element 42 which is adapted to become sufiiciently heated with current from the battery to ignite a cigar or cigarette. The stem 40 including the upper portion 4| is made of heat resisting material such as clay or the like. The upper portion 4| is recessed so as to receive the coiled resistance element 42 whose ends are connected by conductors 43 with socket terminals 44. The latter are adapted to receive the prongs of a plug 45 connected to a length of cable 46 normally coiled within the bottom portion of the compartment 36 and terminating in a conductor 41 permanently connected to the contact member 31, and a conductor 43 connected to one terminal of a manually operable switch 49. The other terminal of such switch is connected by conductor 50 with a pivoted contact member which, as shown in Fig. 4, is normally urged into engagement with the terminal 35 by means of a coiled spring 52. The contact 5| is fulcrumed on a rod 53 extending across the opening 34 in the insulating plate 33. The plates 33 and 36 are held in place by screws 54.

The cover or lid |2 is provided upon the inner face of its peripheral flange 55 and adjacent to v the fulcrum H with a bracket 56 which is provided with an insulating plate or block 51 arranged to swing the contact member 5| to inoperative position upon closing of the cover l2.

As will be evident, the contact member 5| and the switch 49 are. in series, so that when the cover is closed the electric circuit is broken even if the switch 49 should be closed.

The manner of assembly and use of our improved lighter will be apparent from the foregoing. Upon removal of the bottom plate Hi the dry cells can be slipped into the compartments 28 and 29 and upon attaching the plate 3, the cells become connected in series. If the cover I2 is kept open during this replacement, the switch 49 will be opened'to prevent heating of the resistance element 42. Upon closing of the switch 49, the lighter is ready for use and upon closing of the cover the flow of ourrentis interrupted. If for any reason the cover -|2 should .fail to close properly, the switch .49 can be opened to prevent running down of the battery. I

While the whole lighter can be brought bodily to the end-of a'cigar-or cigarettefor igniting the same, it will frequently be more convenient to pull out the heater element 39 and hold only such element against the end of the cigar or cigarette. Such separation of the heating element from the body of the casing is permitted by the cable 46. It will be evident that the lighter will function satisfactorily even in a high wind and in all kinds of inclement weather. Aside from this advantage over fuel operated lighters,-our improved lighter has a further advantage that no flame is held near the face, so that danger of burning of the skin or of the hair is eliminated. It will also be obvious that with our lighter no fumes of any kind will be drawn into the cigar or cigarette, as is the case with fuel operated lighters.

In the form of the invention shown in Fig. 1, the heating element 39 can be removed for replacement or repair by simple disengagement from the plug 45. In Figs. 6 to 8 there are shown two other satisfactory modes of detachably mounting the resistance element 42 which is of general application not only to the lighters of the present invention, but also to other electrically heated devices. In the form shown in Figs. 6 and 7, the latter being a plan view of Fig. 6 with the resistance element removed, the resistance element is coiled Within a relatively thin refractory disc or the like 58; and when mounted on the tubular stem ormember 40 it slides under and is retained by an over-hanging ledge or fiange 59, the appearance and operation being very similar to thoseof a tubular coil bank. The member 53 is provided with'terminals which in the normal position of said member maintain electrical contact with spring terminals '60 suitably positioned on insulating material within the stem and electrically connected to the conductors 43. The latter may be connected to socket members 44 as in Fig. 1, or they may be more or less permanently connected to the cable 46. It will be evident that the spring terminals act to urge the member 58 against the under side of the ledge 59 to hold said member against displacement. However, other securing devices can be employed together with or in place of the l, spring action of the terminals 6|]. It will be seen that although the stem 43 can be readily grasped between the fingers to remove the same from the casing Ill without interfering with the positioning of the member 58, the latter can be easily slid out of the stem 40 for repair or replacement. Thus, it becomes unnecessary to disas semble the whole lighter (or other heating device of which the separable resistance element forms a part) to remove the resistance element and its immediate support; nor does the whole device have to be transported to a repair shop for replacing the resistance element or for fitting a new member 48 to the device.

The structure shown in Fig. 8 employs a plug and socket connection between the separable resistance element and its immediate mounting, and the stem 40. This type of connection will be preferred in arrangement wherein it is inconvenient to slide a repaired or a new resistance element into position from the side. In this form of the invention, the enlarged top portion 4| of the stem 40 is separate from the main body of the stem and supports the resistance coil 42 upon a suitable refractory member as in Fig. 6. Terminals are connected with the ends of the resistance coil which engage the laterally bent ends of prongs 6| projecting through suitable insulation, below the bottom of the portion 4|. The prongs are adapted to be received within socket terminals 62 connected to the conductors 43. It will be understood that the friction between the prongs El and their sockets is considerably greater than the friction between the stem 40 and its socket 58 so that the parts ll, 40 may be withdrawn from the casing H] as a unit without separating the parts 50 and 41'. If desired, however, parts an and 4| may be provided with releasable fastening devices to prevent their separation in the normal use of the device. The upper edges of the member 4!, assuming that the latter is made of metal, can be bent over to hold the resistance coil with its refractory support in place where it is made of non-flexible material suitably fastening devices made, if desired, to be utilized to fix the refractory disc in place.

The tubular stem M3, 4! or 40. 4| can be made of metal or of refractory or plastic material. The casing with its cover and bottom plate or wall can be made of metal or of various plastics of preferably non-combustible material.

As will be obvious to those skilled in the art, numerous variations from the preferred invention herein described may be resorted to within the scope of the appended claims without departing from the spirit of the invention.
