  • Non-refillable gas lighters include a tube-shaped closed body, which receives liquid fuel that is converted to a gaseous state when it is released. The fuel is released through a valve that is installed in the upper closed end of said body. The valve is next to a knurled wheel, which strikes a pyrophoric flint and produces sparks to ignite the gasified fuel as it is released.
  • lighters In one form of these lighters, once the fuel and/or flint has beenexhausted, a lighter is no longer useable. It lacks an inlet valve through which the fuel reservoir may be refilled. The flint cannot be replaced since it is permanently installed in a blind pocket located inside the fuel reservoir. There is no way to gain access to that pocket. The only wayto replace the flint is by removing the spindle on which the striking knurl spins. But, this is difficult since the ends of the spindle are usually riveted. If the broadened rivet parts are removed, the agents which support the spindle deteriorate, rendering the entire lighter useless.
  • lighters Another form of these lighters is organized around its fuel reservoir and is generally tube-shaped and made of a transparent or translucent, preferably plastic material.
  • the lighter is equipped with a refill valve in the closed bottom through which the fuel reservoir may be refilled.
  • a gas release valve At the top of the lighter are a gas release valve and the mechanical devices which permit adjustment of that valve.
  • the transparency of the reservoir permits continuous viewing of the fuel which remains and permits timely refilling through the refill valve.
  • These lighters also have a stationary ignition device mounted on a tubular rod with a closed lower end. This rod is nonremovably fastened at the upper end of the reservoir and extends down inside same. An expanding spring is installed in said rod, and on top of this is positioned a relatively long pyrophoric flint.
  • Both of these are fas tened to the knurled wheel which strikes the flint.
  • This wheel is permanently suspended from a clamped and riveted spindle that is hung between two integral supports which project out vertically from the top of the reservoir.
  • the present invention provides a liquid fueled, gas emitting lighter without the disadvantages and limitations of prior art lighters.
  • the lighter of the invention is relatively inexpensive and permits both replacement ofthe pyrophoric flint and refilling ofthe fuel reservoir.
  • the lighter includes a hollow, projecting, tapering wedge-shaped, thin width ridge which projects out from the main body and makes the lighter easier to handle.
  • the ridge protects the lever that controls the gas release valve, since it covers the extended end of same, and prevents chance opening of the gas release valve when, e.g., the lighter is carried in a pocket.
  • a relatively strong elastic device like a leaf or laminated spring, places constant pressure on the lever which controls the gas release valve, tending to hold it closed and in place, thus preventing chance gas release. Since the leaf spring automatically closes the release valve, that valve does not need a return spring, normally required by such valves. These springs, due to their small size, are relatively weak, and therefore cannot guarantee a good closure.
  • the autonomous ignition device including a pyrophoric flint and striking knurl, is fitted into the reservoir by simple insertion, and it may be easily removed by pulling it with the fingers in order to replace the flint.
  • the mounting of the knurled wheel on this device has also been specially designed to provide for simple assembly and disassembly.
  • the traditional processes which the ends of the spindle are riveted or the spindle itself is machined and one of the ends threaded have been done away with.
  • the pyrophoric flint and the spring which works it are installed through a lateral opening in the tubeshaped lighter body. Mounting the flint and spring is a quick and easy operation. The screw which is normally inserted axially to hold the spring in place and provide the pressure which same places on the flint is not used in the device.
  • the closure over the open bottom of the body and reservoir of the lighter seals the reservoir against leakage, and is equipped with a valve which allows for repeated injection of fuel into the reservoir.
  • the lighter ofthe invention is essentially made up of the following parts:
  • Autonomous ignition mechanism which can be mounted and dismounted in the body of the lighter by simple insertion.
  • Stopper-like piece which provides for a practically air-tight seal at the bottom of the deposit, which piece is united to the main body ofthe lighter by means of a special welding process.
  • the lighter also hasan optional tubeshaped case or sheath for the top of the lighter with open ends and a pair of aligned notches which are located above the lateral ridge of the main body. In the upper edge there is a rim which is turned inward. The inside is smooth, and at the front there is a groove which holds the knob which regulates the length of the flame.

  • the lighter main body is a molded hollow cylindrically shaped tube 1, preferably made of synthetic plastic material.
  • Body 1 defines interior reservoir 2 for holding liquid fuel.
  • the body may be translucent or transparent so that the amount of fuel left in the reservoir can be seen.
  • the top 3 of the body 1 is closed, and its bottom 4 is open.
  • the bottom is sealed with a special stopper (FIG. 6) which is attached to the body 1 by a special welding process.
  • the top 3 has a pair of tubular pockets 5 and 6, which hang down inside reservoir 2.
  • Pocket 5 is open at the top 7 to the outside, and closed at the bottom 8 and is designed to hold and position a special autonomous lighting device (FIGS. 7 and 12). This device can be easily removed to replace the pyrophoric flint when needed.
  • Pocket 5 has a longitudinal groove 9 along its interior wall which corresponds to a shoulder or rib 9a, located on the lighting device. The device slides into the pocket and is directed to shoot sparks toward the gas release opening in order to ignite the fuel.
  • Main body 1 has a hollow downwardly inwardly tapering ridge 10 which projects radially outward and extends from the top 3 ofthe body 1 almost to the bottom 4. This ridge is designed to:
  • e. provide space for other features, small complementary suspension devices, such as a magnetic inset, for example.
  • pocket 6 Parallel to pocket 5 is second pocket 6 also integrally formed inside reservoir 2.
  • the diameter of pocket 6 successively decreases through smaller chambers ll, 12, and 13. It has a small hole 14 in the bottom which leads to the reservoir.
  • the gas release valve is housed in pocket 6.
  • Main body 1 has two parallel, facing homologous rises 16, 17 above the top 3 of the body and perpendicular to it.
  • the rises are positioned on the edge of top 3 and form with it an extension such that the external sides 18, 19 have the same curved form, and the internal sides 20, 21 are straight, and parallel to one another, and the separation between them is equal to the width of the outside of hollow ridge 10, to the width of the laminated spring, and to the width of the lighting mechanisms.
  • Each rise is shaped in the form of a right quadrangle.
  • One vertical side 22 of each rise near ridge 10 has a respective angular notch 23, 24 whose upper edge 25 is horizontal and whose lower edge 26 is slanted. On the inside this forms a gradation 27 whose length is equal to the height, the larger side acting as reinforcement.
  • the lighter may be optionally equipped with vertical grooves which run over the circular recess 28 and hold the metallic cap or sheath 29 of the lighter in place. These grooves serve as guides for the inside pivots or ribs 280 of cap 29 when it is mounted on the body and direct these pivots toward recesses 28 in the body where they are held. Given the smaller diameter at the bottom of said groove, the cap can be installed without forcing.
  • the upper rim 30 of cap 29 rests on the orthogonal seams 31 which have said quadrangular-shaped extensions l6, 17 at the top 3.
  • the flap of said sheath 29 is set and fixed into place in the section 31a where the perimeter of the body 1 decreases slightly, just below the top 3.
  • the open bottom 4 of main body 1 is closed off with a stopper 32 which is solidly attached to it, and which bears the refill valve; the inside diameter of said body 1 increases at the bottom, which means that the wall is narrower at that point.
  • the lighter is designed to increase the distance traveled by the gas fuel before being released through the release valve, assuring that when the gas reaches the outside it is in optimum condition for burning.
  • the lighter also prevents turbulence when the fuel is released, thus providing for greater stability of the flame.
  • the lighter gas release valve is located in cylindrical pocket 6. It includes a screw-on cap 34 which has a recess 35 approximately half-way up its perimeter.
  • the upper edge 36 of recess 35 and base 37 of cap 34 are bevel-edged so that when cap 34 is mounted on the lighter, it is forced past a circular rib in pocket 6.
  • the upper edge of this pocket rib is also beveled, so that when the valve is pressed downward, the bevel edges slide against one another and distort the material of the cap until cap 34 is positioned with the pocket rib in recess 35 of the cap.
  • Cap 34 is internally screw threaded to hold valve body 38 which consists of a cylindrical tube open at one end and closed at the other, and in the center of which there is a small hole 39 which is circled on the inside by a wide rim 40 on which a cylindrical elastic piece 41 is placed and either left to lie loosely or held in position by means of an upper cylindrical axial extension 42 which extends into the piston or burner device 43 from underneath, forming the valve with which this hole is opened and closed.
  • This bodkin consists of a semi-circular piece whose ends are folded towards the center and in the center of which is perpendicular arm 45 so that it may be handled more easily.
  • valve body 38 There are three peripheral recesses in the valve body 38; one 46 which separates the grooved zone from the screw-cut zone another 47 which extends from the latter downwards to the bottom, close to which the third 48 is located.
  • ln recess 48 is a resilient O-ring 49 which puts pressure on body 38. This O-ring rests on the inside wall of the intermediate gradation 12 of pocket 6, sealing it air tight to prevent gas leaks but allowing said piece to pivot.
  • a cylindrical piston or burner device 43 is fitted into the smooth inside of the valve body 38 but in such a way that it can move up and down or rotate. This device rests on the resilient piece 41 which closes the hole 39 in said body.
  • Piston 43 has an axial hole 51 which opens at both ends and which branches off in various radial arms 52 which radially open to the outside in an area where the diameter of piston 43 is smaller. Hole 51 decreases in three gradations from bottom to top, the widest area being the bottom in which the resilient seal 41 is held in place.
  • Downward closing pressure on device 43 is provided by a laminated leaf spring 65 located below lever 55, which forces the latter to maintain a constant closing pressure by compressing the resilient seal 41 against the lower end of gas release hole 39 of the valve body 43.
  • piece 66 At the narrow bottom of the pocket holding the valve is placed piece 66.
  • This piece has a cylindrical shape and is short in length, and its bottom 67 is extended in the shape of a diametrally grooved cone frustrum 68, the ends of which double back orthogonally and continue upward until they reach the top 69.
  • a knob 70 In the center of the top there is a knob 70, also conical in shape and extended into a spherical bonet, where the central groove of the bottom 50 of the valve body 38 is set and fitted into place.
  • element 71 Between the body and the special piece there is an element 71 which limits the amount of gas released and which consists of a porous foam, more specifically, it is a polyuretane disc which is compressed between the two, such that the disc pressure is produced exclusively in its center.
  • the gas rises in liquid form through a wick 72 which is held in hole 14 leading from reservoir 2 to the cavity where the valve is housed, and through the special cylindrical piece 66, which presses the top against the bottom of the cavity.
  • REFILL VALVE The refill valve is located in the stopper which seals the bottom of the fuel reservoir 2.
  • Stopper 32 has in its 1 center a tube shaped projection 73 in which the refill valve is installed. Its upper inside edge is beveled and below it there is a perimeter recess 75 whose upper angle edge 76 is slanted. The lower edge forms a perpendicular gradation which acts as a check for a special piece 77 which penetrates the wallls of said recess by pressure, and is thus held in place by a bond.
  • Special piece 77 consists of a thick washer or support whose external appearance is the reverse of the one described for the frame; it has a hole which is larger at the top and at the bottom becomes a rim or flap 78 rather like a collar.
  • the spring 79 which keeps the gas opening closed rests on the bottom of this piece around the collar.
  • the body of the valve consists of a cylindrical piece 80 which has various gradations and ribs, in accor dance with their function.
  • the upper part 81 is grooved by longitudinal, parallel and equidistantly spaced grooves in order to allow the gas which enters through the tube'shaped collar 73 to flow in through these grooves and the support-washer into the reservoir 2.
  • This upper part 81 penetrates into and is guided in its vertical upward and downward movements by the opening in the center of washer 77.
  • the diameter of piece 80 is enlarged to nearly the size of the inside diameter of the spring 79, acting as a guide for same and thus preventing the deformations which could come about as a result of compression, due to the force transferred to the other end of the spring by means of an annular rim 82 on which it rests.
  • Collar 73 has, close to its lower edge, a narrowing of smooth sides and sharp angles, which leaves a center hole, through which a rod 84 protrudes.
  • the valve is extended to this'rod, which has various parallel planes 85 making the transfer of gas from the refill bottle to the valve easier.
  • a sealing gasket 86 is placed around the rod 84 and compressed against the upper side of the gradation 83 of said collar and the lower edge of the valve rim 82.
  • the coil spring 79 is permanently compressed and the sealing gasket 86 is under constant pressure, which keeps the gas opening normally closed.
  • This lever is made up of a flat stamped piece 55, preferably rectangular in shape, from whose longest edges aligned appendages 56 and 57 project in opposite directions. Appendages 56 and 57 constitute points of support for movements of the lever to establish the open and closed positions for the gas release valve 43, and act as checks to limit the upward movement of lever 55.
  • a pair of axial, homologous and reciprocally parallel extensions or rods 16, 17 project upward from the upper part of the body of the lighter for installation of lever 55. Said lever is suspended between the two extensions. Rods 16, 17 each have an angular notch 23, 24 in which the appendages 56, 57 of the lever 55 are placed. Lever 55 is installed in such a way that it can rock between the open and closed positions, thus controlling the release of gas.
  • lever 55 One of the shorter edges of lever 55 is narrowed, and at its center has a notch 60 which delimits two homologous arms 58, 59 which are fitted into a groove 54 in the tip 43 of the gas release valve.
  • lever 55 When lever 55 is put under pressure, it rocks, resting its appendages 56, 57 on the angular bottoms of their respective positions 23, 24 and causes valve 43 to raise up and allow gas to flow out.
  • Lever 55 has been improved in the following important manner: the edges ofthe operating sides are folded downward, both side and back, forming retention and centering rims 63, 64 around the upper wing of the laminated spring 65. This puts constant pressure on the lower part of the lever, thus returning the valve 43 to the closed position.
  • the lever 55 has a central opening 61 with a notch 61a designed to allow the lighting device described below to pass through.
  • Lever 55 is under pressure from laminated spring 65, which keeps it in the closed position at all times. In order to release the gas, pressure must be brought to bear on lever 55 in order to overcome the resistance of said laminated spring.
  • Spring 65 consists of a folded over V-shaped elastic lamella, and is positioned between the top 3 of the body 1 of the lighter and the bottom of the opening lever 55 for the gas release valve 43.
  • the spring has a notch 650 open in front, that is at its vertex, and has a rim 65b diverted downward at an angle from the lower wing. which extends into the opening in the upper edge ofthe wedge shaped ridge 10 of the main body, holding the spring in place, and preventing it from moving upward.
  • the upper wing of spring 65 rests against the bottom of lever 55 which controls the gas release, and is centered or retained by the peripheral rim or flap 63, 64, which borders the operating sides of lever 55.
  • the lighting mechanism is an autonomous device. It is built around a cylindrical tube 87 one of whose ends is closed. One part of this tube has been cut away 88 from the lower end, by means of two perpendicular cuts, one of them longitudinal and the other through the diameter. A semi-cylindrical cavity is produced, which is an extension of the center opening 89 of tube 87. The lower end of this cavity is closed by a semicircular divider 90.
  • tube 87 is integral with a U- shaped bodkin with sharp angles centered above it, whose eyes 91, 92 are grooved.
  • Pyrophoric flint 93 is inserted through the lower open part 88 of tube 87 as is the spring 94 which holds the flint against the knurled striking wheel 95.
  • Spring 94 is under pressure until it is completely inserted into the tube cavity resting its end on the bottom semicircular divider which closes it off.
  • This system provides for complete independence between the ignition mechanism and the other elements of the lighter, and avoids complicated machining work.
  • the knurled wheel has a special construction for which reason the arms 91, 92 of the bodkin which supports the ignition device from above, each have grooves 96, 97, which each converge inwardly toward the center of the bodkin, FIG. 12. This center area is enlarged, to a circle, thus forming the same number of small gradations.
  • the pivots 98, 99 which form the spindle of knurled wheel 95 pass through grooves 96, 97 and are squeezed inward and extend by pressure exerted by the converging grooves until the pivots 98, 99, become coupled to the circular enlargement, preventing said pivots from sliding out of place.
  • the bottom 4 of fuel reservoir 2 is sealed by welded on stopper 32 which forms a practically leakproof closure.
  • the stopper has a tube-shaped vertical projection 73 which passes through the center of the reservoir.

  • Stopper 32 is encircled by an annular crown 102, 103 extending perpendicular to the top.
  • a peripheral gradation 104 which has a slanted section groove 105 in its upper edge, the upper base of which is directed inward, thus forming a sharp angle.
  • stopper 32 which closes the open end 4 of the main body 1 must be practically leakproofinasmuch as the hollow main body forms the reservoir 2 which is to hold the highly volatile liquid fuel.
  • the invention includes a special process to establish a close union between the closure piece 32 and the hollow main body 1.
  • This process can also be used to effectively weld together pieces of thermoplastic materials, where the parts to be welded are interlinkable circular sections.
  • the welding method proposed herein is designed to overcome these disadvantages when the pieces to be welded have a small thickness.
  • This method offers the advantage that no burrs are produced on the outside, and of course it does not require protruding gradated rims. In short, it makes possible the union of pieces with annular coupling zones, without any irregularities on the outside.
  • One of the pieces to be joined is formed with an an nular recess in its inside wall.
  • a slanted section and circular groove are located on the exterior periphery exactly at the bottom of the rise or circular recess of the first piece.
  • Stopper 32 which closes the bottom 4 of fuel reservoir 2 must be integrally united to it, since the pressure of the extremely volatile liquid so requires.
  • Stopper 32 has two concentric tube shaped portions 73, 102 and 103 united by the base.
  • the center one 73 is the highest and its upper blunt edge 74 is turned inward, forming perimeter gradations 100, 101 where the special piece 77 is positioned and held in place.
  • On the inside it has a narrowing 83 through which the rod 84 slides, and which at the same time acts as a base for the resilient washer 86 which seals the groove formed.
  • This tube-shaped piece 73 extends downward forming a circular rim 106 joined to another concentric one 107. This latter is formed in the same manner by the external tube portion 102, 103 by means of radial rises 108 which reinforce the base and provide for the fastening necessary for welding.
  • the piece 32 On the outside the piece 32 has a peripheral rim 104, with the surface slanted inward. In this rise it checks and holds the tube shaped. body of the lighter l in place, leaving an angular cavity on the inside 109 and a pocket in the upper part formed by the curved edge of the tube-shaped portion, designed to hold and be filled by the welding burrs.
  • the body 1 is fitted with an annular inside recess 33, and the other piece 32 with an also annular groove 105.
  • Piece 32 is made to spin by any mechanism in the inside of the main body 1 and the heating due to friction'causes a softening of the parts; once they reach a certain degree of fusion they fill the spaces or grooves with the excess material, making for a stronger bond between the two pieces.
  • a tube-shaped cap or sheath 29 is provided in the upper part of the lighter to cover the mechanisms in its head. Both ends of this sheath are open, the bottom smooth, and the top circled by a rim 30 which rests on the edges 31, 31a.
