Description
J. SINKO CIGAR LIGHTER Aug. 2o, 1935.
File@ Oct. l5, 1931 Patented Aug. zo, 1935 UNITED STATES PATENT OFFICE 3 Claims.
This invention relates to electric cigar lighters of the wireie ss" type, and has reference more particularly to that class of such igniters wherein the ignitcr coil is mounted within the chamber 5 of a hollow knob, and the front wall of the latter is provided with a central opening, preferably closed by a window, through which light rays from the igniter coil are visible.
The purpose or object of the invention is to provide an improved cigar lighter of this type well adapted to signal its incandescent condition, automatically maintain a normally separated condition of the contact members, and maintain a secure grip of the removable unit on the stationary unit against accidental displacement or jarring off, at the same time permitting easy application and removal.
The invention, in a preferred embodiment thereof, is illustrated in the accompanying drawing, in which-- Fig. 1 is a longitudinal axial section, showing the contacts separated.
Fig. 2 is a similar view showing the knob pushed inwardly, and the contacts closed.
Figs. 3 and 4 are transverse sections on the lines 3-3 and 4-4 of Fig. l.
Fig. 5 is a transverse section on the'line 35 of Fig. 2.
Fig. 6 is a perspective detail of a friction sleeve that is mounted in the removable member of the device.
Referring to the drawing, and describing tirst the stationary unit or holder, I designates a fragment of the usual sheet metal instrument board, formed with a hole l I in which is mounted the threaded shank of a thimble I2 secured in place by a nut I3. Through the thimble I2 is led the usual insulated circuit conductor I4 from the positive side of the battery. On the reduced inner end or neck of the thimble I2 is mounted the countersunk face of an escutcheon ring I that lies in contact with the instrument board I0, and nested in the countersunk face of the eseutchcon ring and also mounted on the neck of the thimble I2 is a hollow sheet metal post I6; the escutcheon ring and post being locked on `the thimble I2 by swaging down the endof the neck over the base of the post I3, as shown at I'I. The inner end of the circuit conductor I4 beyond the thimble I2 is stripped to expose the wire I8, which, in the present instance, consists of a twisted strand oi' fine copper wires, and on this exposed end of the circuit line is mounted a short metal sleeve I9. Fitted onto the sleeve I9 is an insulation disc 20, the periphery of which nts within a cup-shaped spacing member 2i, which latter snugly ts within the hollow post I6, lying against the bottom wall of the latter, said cup-shaped member 2| beingy formed with a forwardly offset central portion 2i that enclrcles with clearance the sleeve I9. Also mounted on the sleeve I9, and lying against the forward face of the insulation disc 20, is an annular contact terminal comprising a disc 22 (Fig. 4) formed with four spaced forwardly projecting contact fingers 23. Cup-shaped member 2| may be locked in place by a plurality of indented lugs 24 formed in the circumferential wall lof the hollow post I6. The forward end of the sleeve I9 is formed with a head 25 having a central countersink, and its rear end is swaged over a brass washer 26 that, in turn, lies against an insulation washer 21 bearing against the offset central portion 2i of the cup-shaped member ZI, whereby the members 2I, 20 and 22 are all securely clamped together as a unit on the circuit conductor. To lock the end of the latter in the sleeve IB, the strands are spread into the counter-sink of the sleeve head. a thin washer 28 is then laid over the ends of the strands, and the metal of the head is then swaged down over the disc 28. It will thus be seen that the contact terminal 22 is in metal contact with the circuit line through the metal sleeve I8, while the cup-shaped member 2I and the hollow post I6 are insulated from the circuit line.
Describing next the removable or portable unit, 29 designates a hollow knob of bakelite or other nonconducting material, the iront or face wall of which has a central opening therethrough, the outer end of which opening is enlarged-to form a seat Iona translucent window 30 of plain or colored glass, amber, or other translucent material that is preferably mounted in a thin metal shell 3i set in the enlarged end of the opening. The knob 29 is formed, behind the window 30, with an internal annular rib 32. Fitted within the rib 32 and extending inwardly thereof is a hollow supporting member, the outer open end o! the cylindrical wall 33 of which is swaged over the outer side of the rib 32, as shown at 33. The supporting member has at its inner end a transverse wall 34 that is formed with a central hole into which is driven a low boss 35' formed on the face of a nut 35, whereby the nut is `locked on said wall. The wall 34 is further formed with a circular row of holes 38 Fig. 5), the purpose of which is to permit the light rays to pass from 'the igniter coil through the supporting member to and through the window 30. The wall 34 is extended beyond the diameter of the cylindrical porlll tion 33 to torni an. abutment fiange 3 i' ing as hereinafter described. Encircling the cylindrical wail 33 is a sleeve Siorrned at its outer end with a flange 38 which abuts against the inner side oi the rib Encircling and slidable on the hollow post i6 is a friction sleeve 39 formed with a laterally onset transverse wall w'that is centrally apertured to slidably engage over the sleeve 3l and normally abuts against the iiange 34', and between the ange 38 and the wall dit is a coil compression spring 4i. As best shown in Fig. 6, the friction sleeve 391s formed with a, plurality of inwardly struck fingers t2 that, as the friction sleeve is telescoped over the post iE, are expanded into the plane of the friction sleeve, and thus afford a friction grip on the post.
Mounted in the nut 35 is a screw d3 that projects inwardly of the transverse wall 34 of the supporting member, and clamped thereon between the head of the screw and insulation washers-44 by means of a nut te is a cup-shaped contact member 4t. Within this contact member is the usual igniter coil di, one end or which is anchored to the head or the bolt 43, while the other end is anchored in the circumferential wall of the contact member 4t. The bottom wall of the contact member 46 encircles the screw 43 with clearance, as shown, so as to be out of electrical contact with the latter. Between the bottom wall of the contact member 46 and the igniter coil tl is a. mica washer 43, and this washer and the bottom wall of the contact 46 are formed with registering openings 49, best shown in Fig. 3, to permit the passage of the light rays from theigniter outwardly through the holes 36 of the supporting member to and through the window 30.
'Ihe spring 4l normally maintains the contacts 23 and 46 separated, as shown in Fig. i. When the knob is pushed inwardly, the spring 4l Iis compressed, and the contacts are closed, as shown in Fig. 2. The current then flows from the circuit conductor I8 through sleeve I9, contacts 23 and 46, igniter coil 41, screw 43, nut 35, walls 34 and 33 of the supporting member, sleeve 3l, spring 4I, friction sleeve 39, and post I6 to esucutcheon ring I5 and thence to ground through the metal instrument board I3. From the foregoing it will be seen that the sleeve 31 forms a part of the grounding circuit, and it also, through its abutment against the inner side of the rib 32, cooperates with the ange 33 in supporting and centeringl the cylindrical body 33 of the supporting member.
.When the igniter has become incandescent, the knob is withdrawn bodily from the post I6, and when subsequently replaced, the spring 4I automatically maintains the removable unit sulciently retracted to insure separation of the contact members. When the removable unit is withdrawn the friction sleeve 38, of course, comes with it, being clamped and centered between the'inner end of the spring 4I and the abutment iiange 34 of, the supporting member.
I claim:
