LIGHTER Application December 27, 1935,,Serial No. 56,309 In Great Britain February 20, 1935 23 Claims.

This-invention relatesto-lighters which employ a catalyst for .igniting cigaretttes and the like, wherein the vapor of alcohol or other vaporizable L liquid carried by absorbent material is employed 'for'eifecting such action upon the catalyst, in the presence of atmospheric air, as will render such catalyst incandescent; so thatthecigarette or the like applied thereto and drawn upon, may be ig- M nited.

In catalytic lighters ithas beenfound that if thecatalyst is held in the presence of fuel vapor for a prolonged period, the lighter being closed, the confined vapor will condense upon the catalystand render it'inactive until said catalyst has been dried out.

zii factorily is attributable inno small measure to inability of the suction applied through the cigarette to draw'sufiicient or proper mixture offuel vapor and air for contaction with the catalyst.

2 3* Therefore my improvements, comprised in this application, which is a continuation in part of my application Serial No.. 54,215, filed December 13, 1935, include the provision of means, operable by the closing of the cover of the lighter, to isolate or remove the catalyst from communication with the fuel vapor and to seal the fuel egress opening and air admission vent, to the end that in the inoperative state of the lighter, no opportunity may be presented for the, collection upon 'the catalyst of condensation from the fuel vapor. Further myimprovements include the provision of a, passageway for conducting atmospheric air from the vent to the, base of the fuel chamber and in the provision of means for localizing the fuel carrying absorbent material to produce a vaporspace substantially completely surrounding the latter and communicating with the air passageway so-that suction applied at the top of the lighter will induce a flow of air toenter the passageway and commingle with the'fuel vapor in the vapor space, the mixture to be drawn to the catalyst to incandesce the same.

An object of the invention includes the arrangement of a lighter comprising a fuel chamber with'a fuel egress opening, and an air admission passageway to the fuel chamber, over which fuel egress opening a catalyst holder is situated when' the lighter is in use and wherein the catalyst holder is isolated from the fuel opening when 55""the lighter is in its inoperative condition. In

It has been further. found.

(01. 67-7) this arrangement the catalyst holder is disposed to be slidable over the fuel opening by a connecta ing arm between'the catalyst holder and a hinged cap or cover which is adapted when opened to bring the catalyst into connecting with the fluid opening but which cap'or cover on being closed, removes the chamber from this position and at the same time, seals the fuel chamber and air admission passageway, the association between the catalyst and the connecting arm being such that the catalyst holder may readily-be removed upon opening of the cover or cap for the purpose of filling the fuel chamber through the fuel open- A further object of the invention resides in the provision of a vapor space surroundingthefuel carried absorbent material, whereby the; air drawn in through the passageway readily com-' mingles with the vapor in the said space for coaction with the catalyst in .the catalyst holder when the cigarette or the like is drawn upon; And for this purposemeans are provided for confining or localizing the said absorbent material. Another object includes the provision of means for hermetically sealing the bottom of the fuel chamber or casing.

Inthe accompanying drawings I show what I now consider to be a preferred form falling within the scope of. the invention as hereinafter claimed. The disclosure is not to beregarded as restrictive but rather to illustrate an embodiment of my in? vention, which ,it is. understood may take many other detail forms.

The numeral 26 indicates the wall of a fuel chamber or casing which may be of stream-lined or other suitable shape in cross-section, and adapted to contain a vaporizable fuel vehicle. The lighter has a cap or cover 28 hinged to wall 26 at 2? which together with the member 28 completes the closure means. A top plate 35 forming the upper wall of the casing or container has a fuel opening 42 and an air duct or vent d3, EX- tending from vent 43 to near the bottom 48 of the casing is a tube or passageway a l. Within the casing is a wick which acts as an absorbent for the fuel which may be alcohol fed into the casing through opening 32. Upon the top plate 35 a combined catch plate and slideway 3G is superimposed, one end of which has an upright member 33 carrying a stud or release button. 32 extending through an opening in wall 26 and the other end of which has another upright member 33' engaging an expansion spring 31. Spring 31 is arranged so that normally the button 32 protrudes through opening 0 in the position shown in Figure 1 but so that by pressing the button 32 inwardly against the force of spring 37 an opening G in the raised end 33 of plate 35 may be caused to release or engage a stud or pin Y on the cap or cover 28. The slideway 34 has a cutaway part in its centre forming an opening C so that in any position it does not obscure the opening G2 or $3. Expansion spring 3'! is located around an extension arm 38 of slideway 34, which arm passes through an opening 39 in the upright portion at of the fixed cover portion 35.

The catalyst P which may be composed of a suitable spong platinum composition or the like is housed in a chamber or holder 55 which consists of a base plate or slide 55 having a collar 65 and a cup 64 having an opening 65. Slide 65 is press fitted onto cup 65. Catalyst P is located in cup fi l over opening 66. A perforated plate or screen S of heat resisting material is placed over catalyst P which is held in position by a retainer ring R. Another perforated plate or screen (not shown) may be positioned on the bottom of the cup covering opening 66 below the catalyst. Slide 65 has two catches 55 which project upwardly. The cover or cap 28 is hinged to wall 26, and pivoted or hingedly secured at 29 to the cover is an arm or pusher 38 of which one end is bifurcated, the extremities of each llimb 52, 53 having a detent or notch which may be shaped as shown in Figure 24 and engaging the catch 55 of slide 65. A spring 3! presses on the arm or pusher 30 and against cover 28 so as to effect the engagement of 54 and 55 and also acts as means to swing or force open cover 28 when release button 32 is pressed inwardly. The base plate or slide 65 is provided with two channel members 5?, 58 which uide the shank portion 59 of slideway or catch plate 34 and when the cover 28 is open, i. e., in the operative position. shown in Figs. 3, a and 5 the catalyst holder 56 lies vertically above the fuel opening 42. In closing and opening cover 28, pusher 32] will cause holder 55 to slide forward and backward over opening 42, and when the cover 28 is closed the holder 55 will slide away from opening G2 to an inoperative position. Two grooves 50, 6| are provided in top plate 35 to clear the guides 51, 58. The arm 38 carries on its underside a gasket M which may be a pad of rubber composition or the like and a stud or button 51 projects from the upperside of arm 30. When the cover is open pad 4! is clear of the fuel opening 42 and air opening 43, but when the cover is closed arm 30 moves holder 5% to the position shown in broken lines in Figure 1, and the pad 4| is brought into a position over the openings 42, 43, the cover 28 exerting a slight pressure on the stud 5| to ensure that the pad effectively seals said openings,

To localize the wick or absorbent material 66 to provide a vapor space there surrounding an upper screen or perforated plate 45 and a lower screen or perforated plate 4'! are provided which are spaced from the top and bottom respectively of the casing to provide the respective fuel vapor and air passages 68, 6?. Screens d5, M are preferably arched as shown in Figs. 11, 12 to facilitate maintainance of respective vapor spaces 58, 61. The wick 46 is, and screens 45, A? may be, confined within the casing so as to provide the fuel vapor and air passages 49, 5E} communicating with passages 68, 61. Tube 44 passes through the screens 45, 41. A complete circuitous path is thereby provided on either side of tube M for the commingled fuel vapor and air to reach the catalyst P.

It will be seen from the above that when cover 28 is closed the fuel chamber is sealed and the catalyst holder or chamber 55 is removed from the fuel opening 42 whereas on opening cover 28 the holder 56 is brought into an operative position. A cigarette or the like held against the screen S of the catalyst holder 56 will be lighted if suction be applied by drawing upon the cigarette,

'owing to vapor and air (entering the casing through duct 43) mixing in the passages in the casing and entering the catalyst holder in the presence of the catalyst incandescing the latter.

The container may be refilled at any time by removing holder 58 from pusher 3i and slideway 341. This is accomplished by sliding holder 56 away from pusher 3&3 along slideway 3A (in which case catches 55 leave the notches 54) and detaching holder 56 from slideway 34 by passing the uides 5?, 58 through the notches 62 in slideway 34, The holder may thus be removed from opening 42 into which the fuel may be poured. Replacement of holder 55 is readily effected by slidingly engaging the holder with slideway 343 through notchesv E2 and by sliding the catches 55 under the detents 54.
