CIGAR LIGHTER.

Application led August 16, 1926, Serial No. 129,363. Renewed November 5, 1928.

The invention relates to electric cigar lightl ers.

One object of the invention is to provide a portable lighter which is of new and improved construction and is provided with an automatically operating switch to pass current through the resistance element when the lighter is lifted from the table or its support.

Yln devices of this type, it frequently occurs that the casing or body of the lighter is tipped over, -and when this occurs, the .switch automatically closes, so that the resistance element will become heated, with the consequent iire hazard; Another object of the .1nvention is to provide an electric lighter which will right itself, if it should be accidentally tipped, so that the switch will not be, or remain, closed.

Other objects of the'invention will appear from the description.

The invention consists in t-he several novel features hereinafter set forth and more particularly defined by claims at the 'conclusion hereof.

In the drawings: Fig. 1 is a vertical section of a device embodying the invention. F 1g. 2 is a section on line 2 2 of Fig. 1, parts being Shown in elevation. F ig. 3 is a perspective of the device. Fig. 4 is a section on line 4 4 of Eig. 1. Fig. 5 is a plan view of the resistance velement and the parts associated therewith. l

'lhe invention is exemplified in a casing or container comprising anupper member 7 and a lower member or base 8 which are slidably connected together to permit their separation when the upper niember is lifted independently of the base. The upper member i s enlarged at its lower end and itsupper portion is constrieted so it may be conveniently grasped between the fingers for manual minipulation. 'lhe base is provided with a cushion 9v adapted to reston a table orother support. The

base is formed of heavy material, such as` brass, and the upper member is made of light insulating material. Exteriorly, the bot-tom face of the base is convex so that any lateral shift of the upper member will causethe casing to rock or roll on its c o'nvex lower face to change the center of gravity, so the weight ol the material will be always distributed so the casing will assume its upright position by gravity as soon as-it is released. A post 10 has its lower end threaded into the base 8 and extends through the center of a crosswall 12 iii the lower end of the upper member 7. The post is axially slidable in said wall, to forni a sliding connection between the member and the base, which is utilized to operate a switch which controls the operation of the resistance element. A socket 23 is foi-ined in member 7 to contain some of thc circuit connections for the resistance element. A plug 13 for the resistance element is removably held in the upper end of the socket 23 of member 7.

insulating material and is threaded to the upper constrieted end of member 7, so that the plug will be removably clamped to the casing. Plug 13 is formed of insulating material, is built up of a lower member 14a, on which the fiange 14 is formed, a top member 14b and a ring 14C interposed between members 14a and 14". The top face of member 14b is formed with a sinuous groove 16 in which is laid the resistance element 17. The terminals of element 17 are .electrically connected to screws 18 and 19 respectively which extend through and secure the plug-members together. Each of said screws has its lower end threaded into a contact stud 20 belowthe plug member 14a and in socket 23. A sheet of mica 21 is held over the resistance element by a flanged ring 22.

The circuit for the resistance element comprises a conductor 25 which passes through an opening 25i in member 7 and is connected to a bolt 26 which extends through the wall 12 und a conductor 28 which also passes through said opening and is connected to the lower end of a bolt which has a shank extending' through the wall 12 and a contact stud 29 at its upper end. An upwardly exerably made oi Said plug has a flange 14 which 1s engaged by a collar 15 which is preftending resilient contact strip 3U is adapted i to engage one of the studs 20 and has its lower end secured by bolt 26 to wall 12. A similar resilient contact-strip 32 has its upper end disposed to engage the other stud 20 and its lower end is secured to the wall 12 by a bolt 33. An arcuate strip 34 connects bolt 33 and the shank 35 of a bolt with a contact stud 35 at its upper end which is diametrically opposite to the stud 29. The circuit is normallyinterrupted between studs 29 and 35. A contact ring 36, adapted to close the circuit across said studs, is secured to material which is ixedly secured by a may be modified within the scope of the ap-A nut 38 on the upper end of post 10. A light spring 40, coiled around the upper end of stud 10, is interposed between the washer 37 and the wall 12 to supplement gravity in forcing Vthe members 'l' and 8 together, so that ring 36 will open the circuit except when the base member 8 is suspended and is entirely free to be lowered by its own weight and when the lighter is held in a substantially upright position.

When the member 7 is lifted ofi1 a table or other support, to apply the resistance element to a cigar for lighting it, base 8 will be lowered by gravity awa)v from member-W. Such separation will move the stud 1() downwardly until the contact ring 38 engages the contactstuds 29 and 35 to bridge the gap between said studs, to close the circuit as follows: conductor E25, bolt 26, strip 30, stud 20, screw 18, resistance element 17, screw 19, stud 20, strip 82, bolt 83, strip 84, stud 35, ring 36, stud 29 and conductor 28.

The invention exemplifies a portable cigar lighter of the type which is adapted to rest on a table or support, which will right itself in event that it is tilted; in which `the switch is automatically operated by relative movement of the casing members; in which all of the circuit connections are carried in or by the upper casing member', in which the resistance element ismounted in a plug which is removably held in the upper casing member; one which can be readily assembled and'produced at a" low cost.- a
