The invention relates to cigar, cigarette and tobaccolighters and particularly aims to present .a device adapted to combine these uses.

It is 'a special aim to evolve a novel mechanical device having an electrical heating element extensible, by simple manipulation, into a pipe bowl, to properly contact and ignite the tobacco at Whatever level it may be therein. It is also an important object to present a novel and simple device to effect proper extension of the heater or igniter element with a minimum effort on the part of the operator, without requiring electrical propulsion. One accomplishment of the invention is the perfection of a portable lighter which may be operated with greater certainty in lighting tobacco pipes by reason of certain novel functions contributing 'to effective contact of the heater element with the tobacco in the pipe, and yet may be utilized without diminished utility in lighting cigars and cigarettes.

An important object is to evolve a novel and useful mechanical movement applicable to this device and to other uses: for instance, where an implement or tool is to be extended and retracted toengage work or forother purposes.

It is an important object to evolve novel coordination of parts in the operation of an electrical switch and a heater projection means.

Additional objects, advantages and features of invention reside in the construction, arrangement and combination of parts constituting the invention, as a whole, as will appear from the ,fol lowing description and accompanying drawing, wherein Figure 1 is an elevation partly in section of a pipe and my lighter-initially presented thereto for ignition of the tobacco charge.

There is illustrated a lighter comprising a case including a cylindrical tubular handle part 2| having an L extension 22 at its outer end, the whole being formed of a suitable material such as Bakelite or other synthetic gum, or other material found suitable. The end of the handle distant from the L 22 is closed by a plug 23 apertured and suitably adapted to receive and support the lead-in wires 2425 from a suitable electrical source, not shown.

The case may be flattened or otherwise shaped at the junction of the handle and L to, provide a chamber open opposite the L to receive snugly between its sides an operating unit 26, secured in the case in any approved manner and is open at the upper side between these flat parts from the outer end to a line inwardly on the handle a distance beyond a projection of the L, affording a good access opening for assembly and repair.

The outer end of the L 22 is reinforced by a metal ring 21 set permanently therein and serving as a bearing for a heater unit 28, engaged slidably in the L extension. This heater unit consists of a cylindrical slide body 29 of porcelain or other good insulating material, having a circular recess 30 in its lower end in which there is set a coil 3| of suitable resistance material. This body is of the same length as the L 22, and has a reciprocating movement approximating half its length. The heater is preferably of ribbon section, wound in a spiral or other form together with a slightly wider strip 32 of mica or other proper material, whereby an insulation is formed between the coils and the greater width of the mica projected at the lower side forms a guard by which tobacco will be held from direct contact with the material 3!, minimizing accumulation of carbon on the coil. The ends of the coil may be extended upwardly through suitable passages in the slide 29, and connected respectively to the wire and a slack wire 24' led from a switch 33 set in the handle at the lower side near the L 22. This switch is a simple normally open push button switch of any approved manufacture having the button 34 exposed slightly beyond the surface so that it may be pressed by a finger of the hand of an operator grasping the handle while the thumb is extended over the operating unit opposite the L, as will be described. The wire 24 is connected to the lead-in terminal of this switch.

The operating unit as here embodied is adapted to be assembled complete and set in the case simultaneously with the sliding heater unit after all parts are properly connected. It consists of a frame of sheet metal plate bent to form two parallel side plates 36 between and upon which the operative parts are mounted, these plates being connected by fiat top wall parts 31. The side plates have inwardly turned bottom flanges 36 at their lower edges parallel to the top wall and extending from the end wall 38 of the outer end of the handle. The lower edges of the side plates may be cut away from the bases of these flanges 36 so as to extend diagonally inward and upwardly beyond a projection of the L a distance at the top of the case, and the top wall 3'! of the frame may have a lip 39 extended slightly over and set in a part of the top of the case shaped for that purpose and this may be utilized for a permanent or removable fastening by which the frame is held in the case. The junction of the inner side of the L and the lower side of the case is rounded as illustrated.

The frame is formed with a rectangular top opening flush with the side plates and stopping short of the ends of the frame sufficiently to afford proper transverse connecting material. Midway of the length of this opening upstanding ears 4!] are formed on the side plates, apertured to receive a pivot pin 41 carrying a finger piece 42 or operating member in the form of a segment of a cylinder concentric with the pin and of a width and radius to lie close to the sides and ends of the top opening in the frame so that the opening is always closed. On the finger piece there is an extension or knob 43 to facilitate movement of the finger piece by pressure longitudinally of the case, and its outer face may be knurled or ribbed, as at 44.

The finger piece is normally held in initial position as shown in Figure 1 by a torsion spring 45 engaged around the pin 4| within a suitable recess at the right hand side of the piece, one arm of the spring engaging an eccentric pin 46 at the lower part of the piece toward the end wall 38, while the other arm of the spring is extended to a pin 41 connected between the upper parts of the side plates 36.

Below the finger piece a snap-action toggle link device is mounted between the plates 36 the middle pivot of which is connected to the beforementioned eccentric pin 46 by a draw-link 48 located at the opposite side of the finger piece from the spring 45. The toggle device includes a front rectangular ring-link 49 shown in Figure 8 having trunnions 50 at opposite edges pivoted in respective plates 36 while its body portion swings forwardly therefrom. The link 48 is pivoted on a trunnion 5| on the left side of the link at its extreme swinging part, close beside the adjacent plate 36. This arrangement affords a transverse swinging cross bar 52 on this link which forms the middle pivot of the toggle and is coaxial with the trunnion 5!, although this is not essential. The other member of the toggle proper is a two-piece telescopically extensible link with a compression spring confined therein. One piece is a stirrup 53 of U-shape with trunnions 53 at the extremities of its arms engaged in the plates 36 and forming the fulcrum pivot of this member of the toggle although its body portion extends and swings entirely opposite from the middle pivot of the toggle. At the bight of the stirrup, a spring seat pin 54 is extended inwardly in the plane of the stirrup on a radius of the fulcrum pivot, and a helical compression spring 55 is fitted thereon so as to be held in the plane of the stirrup and projected a distance across the axis of the fulcrum pivot. Set in the opposite end of this spring there is a telescope pin 56 having a forked or saddle head 51' receiving the bar 52 of the ring link therein so that the head is held against the bar 52 and compressing the spring at all times, although this compression is less at the extreme limits of the toggle action. The stirrup is of longer radius than the distance from the fulcrum pivot axis to the bar 52 at all times, so that when the toggle is operated the stirrup swings over a longer arc than the middle pivot (bar 52) of the toggle device.

The stirrup is formed with a downwardly extended eye 58 at its lower side in which there is pivoted the upper end of the push link 59 by which the heater unit is projected. The link 59 is connected to the top of the slide 29 in any approved manner. This connection may be in the form of Figure 14, a bar 60 fixed on the slide and having ears 6| at the top of the slide between which ears the lower end of the link 59 is pivotally connected. In this instance the bar is set in a longitudinal channel 62 in the side of the slide, the bar having inturned upper and lower ends 63, the lower one set in a suitable recess 64 in the side of the porcelain above the heater coil 3|. The side of the channel may be undercut and a C-spring 65 allowed to expand therein across the bar to hold the latter securely but removably in place without complication.

In use, the lighter may lie on a table or other support, or may be hung in a bracket or other device, and when to be used for lighting a cigar or cigarette, is grasped by the handle with the forefinger pressing the button of the switch 33 and then presenting to the cigar or cigarette as custornary with other lighters, no operation of the finger-piece 42 being necessary.

In the case of lighting a pipe, the end of the L is presented downwardly over the bowl 69 of the pipe; and both the finger piece 42 and the switch 33 operated, the forefinger of the hand grasping the handle being utilized to press the button 34, while the thumb on the same hand is engaged over the finger piece and the end of the thumb pulled inward against the knob by flexing at the first joint of the thumb. In this way the slide will be projected until the coil mica engages the tobacco '14 in the bowl, and its movement will be checked by engagement with the tobacco, or the pipe pressed downward by the slide until the movement of the finger piece is checked on the case. Return of the finger piece is checked at initial position by a pin 15 fixed in the side of the finger piece so as to strike the upper edge of the side plate 36.

In the operation of the finger piece, the draw link 48 first pulls the middle pivot 52 of the toggle upwardly opposing the spring 56 which is thereby compressed, and as the cross bar 52 passes dead center between the axes of the trunnions 53 and the trunnions 50, the expansion of the spring 56 augmenting the force manually applied through the finger piece causes the pin 56 to thrust the bar 52 rapidly upward, causing a snap action by which the far part of the stirrup is caused to move rapidly downward, and requiring less effort on the knob 43 to complete this movement and to hold the parts extended against the action of the spring 45. The pressure of the forefinger on the button 34 keeps the coil 32 energized and the tobacco under the slide becomes ignited.

On release of the pressure of the thumb on the knob 43, the spring overcomes the resistance of the spring 55 to return movement of the toggle, and the link 48 then presses the toggle joint downward again. As soon as dead center is passed by the bar 52, the device independently snaps completely to retracted position. The switch 33 is opened as soon as pressure of the thumb is relieved on the knob 43, as that pressure is necessary to afiord the necessary reaction to efiect depression of the button 34. Consequently, opening of the switch is automatically caused by release of the finger piece, and tendency to waste current is minimized.

By forming the link 48 with a longitudinal slot receiving the trunnion 5|, instead of a simple circular eye, an increased movement of the slide for a given movement of the finger piece is attained. This is shown in Figure 3 where the link 48 corresponds to the one 48 first described and the initial description may be read on this view as in the others. This link is formed with a slot 16 having its outer end located close to the end of the link, at a point such that on operation of the finger piece, it will engage and lift the link 49 above dead center position, and the length of the slot is such that, its upper end engaging the trunnion 5! on return movement of the fingerpiece, will depress the link 49 to a position slightly below dead center.

On operation of this last described device, after initial movement of the fingerpiece half the full swing, the toggle passing dead center will immediately independently and automatically complete movement of the parts to full and extended position, or until the slide is checked by engagement with tobacco in the pipe. This will obviate need for full operation of the finger piece, and also reduce failure to ignite pipes due to users of the appliance not pulling the finger piece to its full limit, or holding it so operated until ignition occurs.

In order to avoid the possibility that in placing the device over a pipe bowl 69, the slide may strike the side of the bowl or carbon accumulations 68 thereon and its movement obstructed before it reaches the tobacco, I have shown in Figure 13 a construction in which the device will be automatically centered in the bowl. In this instance an inverted external conical seat face 61 is formed on the lower end of the L 22 adapted to partly or completely enter the bowl. As shown the maximum diameter of the seat is less than that of a standard pipe bowl 69, but in case of a small bowl the conical part will partly enter the same and so be centered. Also, with carbon accumulations, as shown at 68, the conical portion will engage the upper part of such accumulation and so fend the slide 29 away from such accumulations. If desired, the conical end of the L may be made of larger maximum diameter so that it will function the same on large pipes as on small pipes. In the present instance the seat element is shown as an encircling rib 10 on the extremity of the L, thus reinforcing the material outwardly of the bushing ring 21.

In production, the complete operating unit in the frame 35 is assembled, and connected with the slide while the whole is removed from the case, the wires 25 and 24' are properly connected also withas little slack as possible. In assembling on the case, the slide is inserted through the open top of the case and started into the passage Ii through the L which is without obstruction, and the frame 35 then inserted between the walls 19 of the case 20, and pressed to final position. A single fastening at l2 at the inner transverse edge of the top plate 3? will be sufiicient to properly retain the assembly in the case, although other fastenings may be applied as discretion dictates. The outer end edges of the frame 35 rest snugly against the end wall 38 of the case and so prevent this portion of the frame from moving upward if the fastening H is provided, and as the lower side of the frame adjacent the wall 33 rests against a shoulder 3 at the outer side of the L 22, the unit is amply supported in the case.

It is obvious that various electrical sources. may be employed to operate this device. It may be constructed in a standard form to operate on a G-vclt circuit such as is common in motor vehicles, and in case of 110 volt direct current circuit, a suitable resistance interposed between the wires 24-25 and the service connection. In case of the 110 volt alternating current, a simple transformer may be employed.

For connecting the coil 3! in a circuit, binding posts I! are shown, these being bars inserted through suitable passages in the slide body 29, projecting at the upper side of the slide, and at their lower ends extending into a transverse passage 18 formed entirely across the slide just above the recess 3t. Apertures open from the recess 3% into the passage 13 near the center of the recess 30 and near one side thereof, and

through these respective ends of the coil 3! are extended, beside the bars TI, to which they are secured by conventional binding means or otherwise attached. The wires 25 and 24 are similarly connected to the projecting upper ends of the bars. utilized if desired.

A cowling o-r hood 80 may be provided to partially enclose the finger piece, leaving its upper part exposed at all times, but having side portions 19 raised beside the finger piece so as to enclose the operative connections and pivots.

In lighting the pipe with this appliance, it is possible to press the forefinger on the finger piece 42 while the thumb is pressed against the button 34. This produces the necessary opposing pressures by which proper operation of the two is secured, and when the finger piece 42 is released, the button 34, with a proper spring element in the switch will move to released position, breaking the circuit. In the claims hereinafter, the thumb may be included in the term finger.

The present construction is such that pressure of the thumb or forefinger on the finger piece tends to draw the handle more firmly into the grasp.

The functioning of the devices 8 to 563 inclusive constitutes these an energy storing means up to the point at which the dead center relation of the parts is passed, and beyond this position the structure operates to release the stored energy and is a means to convey the stored energy into motion of the link 5Q greater in extent than that of the operative connection 48 between the finger piece and toggle.
