FREDEIHOK FRAN RLIN DIER AND MEDERIC PRIMEAU, OF WINNIPEG, MANITOBA, CANADA.

Patented July 2o, 190e.

Application led Januar-y 9, 1909. Serial No. 471,542.

To all whom it may concern: l

Be it known that we, FREDERICK FRANK- LiN Dina and Mnonnlo' PRIMEAU, of the city of 1iimnipeg, 1n the Province 'of Manitoba,

Canada, have invented certain new and use -ful Improvements in Gas-Lighting Appli- `ances, of rwhich `the following is the specifi- .-cation.. The invention relates to improvements in devices to be employed for igniting gases, and which is more especially intended to be used'in connection with stoves in which Vgas or gasolene is v'used as fuel,` -yet' it maybe employed for igniting .gases used for other purposes. A

\ `It consists in certain peculiarities of con struction, andnovel arrangementand operation of the various parts thereof, as will be hereinafter more particularly set-` forth, and specifically claimed. l

' On'ejobj'ect of the invention to 'provide f an' economical, simple', electrically operated igniter for gas and other igntable'substances :which: .of such a nature that'an electric spgarlccan be produced at a desiredtime and point thereby Vdispensing with the employ- -inent of matches and avoiding all inconven- .iences arising from their use.

`Another object is to so construct the ap pliance that there is neither a possibility of the operator reeiving an electric shock when using it'nor of the apparatus becoming short circuited when not in use even if it be laid .upon anelectrical conductor.

'Other objects` and advantages will become apparent when the invention has been. fur ther described.

Fig. l1 is an enlarged detailed longitudinal and central sectional view through .the hand instrument, the section being 'taken in a plane, at right angles to Fig. 2, showing the manner 1n which the wires are connected Y -within the instrument. Fig. 5 is an enlargf-zd detailed perspective view of one end of the instrument.

In 'the drawings like characters of reference indicate corresponding parts in each figure.

1 `^represents`a square box in. which is.

placed tw-o cells Q and 3 forming a battery,

the cells being connected in series and hav` ing the remaining terminal of the cell 2 in electrical connection with the binding post L1.

5 isahelix or solenoid also within the box and ity has one of its terminals connected to the remaining terminal ofthe cell`3 and its other terminal G'interconnected by a wire 7 to a. binding post 8. f

We have considered 'it unnecessary to give a detailed description of the box, the solenF oid, the cells, and their connections, as they are constructed and connected in precisely y the same manner as has been described in a United States application for patent on a gas lighting appliance, Serial #463699,led November 20th, 1908.

9 is a contact making hand instrument -whlch consists infa handle formed from' a tube 10, preferably of metal, and of a length which' is best adapted for the purpose. One end of the tube is closed by a plug or end vwall 11 which is bored centrally and has is secured to the tube rearwardly by screwsl 17 passinginwardly through the tube and into the plate. The opposite endpof the 'spring passes forwardly through `the opening 13 in the .plug and entends fora considerable distance.

18 is a fibrous member forming a press button which is secured vto the spring by screws19, the press button passing into an opening 10 formed in the tube so that the spring can be depressed bythe hand whenr "grasping the tube. We have considered it advisable`4 to make the-spring with' the rear ,22 is a contact plate secured adjustably to the strip by Vscrews which it will be noticed pass through slots 24 formed in 'the plate.

^ The plate can be adjusted by unloosening the screws, as will readily be understood. The free `end of the plate passes through the opening- 13' and extendsconsiderably there-V beyond being turned upwardly and back and litted with a wedge or V-shaped contact piece 22', s uch contact piece appearing normally directly' beneath the free end of the spring 15. Y

25 is a comparatively weak flat spring se-vl cured by a screw 26 to the strip 20 andA it' has its free end extending upwardly and forwardly beneath the spring 15 with which-it i f is designed to make contact.

Y e through the coil 12 and is looped around'a 27 is a wiresecuredat its one end to the binding -post 8 and having its oppositev endin electrical connection with the plate'22 by passing it around one of the Vscrews 23 before 1t is tightened to position. The wire passes screw 28 extending fromthe fibrous strip the screw preventing the wire from being accidentally withdrawn from the tube.A -'29 is a second wire having its one end secured to thebinding post et and' its opposite end passing throughthe coil 12 and electrically connected to the Spring 5 byv passing it around the screw`26 before it is fastened in positionf YThis wire is also looped around a screw 30 similar to that 28 and serving the same purpose; The two wires can be wound together so as to form a single cord'between the instrument and the contacts 4 and 8.

31 is a hook extending fronxthe end wall 11 whereby the instrument can be hung up when it is idle. Y `In order to better understand'the appliance we will now 'describe' its operation,- The contact tip 22' is brought within thel zone of the escaping gas and thepress button 18 is forced downwardly by the pressure of the hand on the instrument. This initially vbrings the extending end of the springv 15 into Contactwith the tip, the "spring touching Ythe tip toward `its base.Y Upon' continued Ypressure ofthe hand the forward portion of the springis bowed and shortly before the free end escapes from the apex 'of' thecontact` tip the spring25 engages' with the spring 15 thereby closing the circuit. By the time the press button -is brought to the level of the tube, that is, when itiis deend of the spring 15 Hips oil' the apex of the contact piece to the position shown indotted 'outline in Fig. 3, and causes a spark to ignite the gas.- When -the pressure of the-jv l.pressed as faras possible' by the hand, vthe i hand is released the forward end of the spring 15 returns against the face of the contact piece and is bowed upwardly before it flips of( the apex. The upward bow of the spring causes it'topass out of contact with` the plate 25before the tiplof the spring 15 escapes from the contact piece and consequently there is no spark when the spring 15 V Vis passed to its upper pr normal position.-

'lhe only advantage whlch we claim 1n this respect is the saving it is,in the battery to have only one spark instead of two. As far as igniting the gas is concerned two sparksv would not be disadvantageous but the second one would be entirely useless if the vlirst werel large enough to ignite the gas. The Contact tip maybe made of platinum if it be found necessary to do so.

' What we claim as our invention is 1.111 a gaslighting appliance the combination with a battery and a helix, of a handV instrument designed to close the circuit, said hand instrument being provided with two extending Amembers adapted tobe brought together, the circuit being closed after such members initially e'ngage,as and for the purpose specified.
