Description: |
| Abstract:
This invention relates to improvements in electric igniters for explosive-engines, and has for its object to provide a simple, cheap, and effective device that can be readily applied to an engine, the particular construction of the parts insuring the production of a spark at each reciprocation of the piston, and also provides for manually operating the working electrode in the same manner as is accomplished by the piston.
With the above ends in view the invention consists in the particular construction and combination of the parts to present a stationary electrode insulated from the supporting frame, and a working electrode comprising a rock-bar having a bent end with beveled terminal which engages the stationary electrode, the working electrode being held normally in contact with the stationary electrode by 'a spring and operated against the action of said spring to break the circuit and cause a spark either by the hand-lever connected thereto or by a projection on the piston which contacts with the bent end thereof, as hereinafter fully set forth and particularly claimed.
Claims:
l. An electric igniter for explosive engines consisting of a stationary electrode C and a working electrode C supported parallel with each other in a suitable frame and insulated substantially as shown, the working electrode comprising a rock-bar the inner end of which is bent at an angle to contact with one side of the stationary electrode, and a handle G secured to the outer end of said working electrode; together with a spring for holding the electrodes normally in contact with each other, and an arm projecting from the piston of the engine to engage the bent end of the working electrode and move the same against the action of the spring at each reciprocation of said piston, for the purpose set forth.
2. In combination with an explosive-engine, of the stationary electrode having an end projecting within the cylinder, a working electrode C comprising a rock-bar one end of which projects within the cylinder and is bent at an angle to contact with one side of the inner end of the stationary electrode, a handle mounted on the outer end of the working electrode or rock-bar, and a spring connected to said handle and to a stationary part of the engine for holding the electrodes normally in contact with each other, substantially as shown; together with an arm secured to the piston of the engine and adapted to strike the bent end of the working electrode or rock-bar O and move the same away from the stationary electrode at each reciprocation of said piston, for the purpose set forth.
3. In combination with an explosive-engine, of the stationary electrode C projecting within the cylinder, a working electrode comprising a rock-bar C' the inner end of which is bent at an angle and the terminal beveled presenting an inclined surface which contacts with one side of the stationary electrode, a handle G mounted on the outer end of the working electrode, and a spring H connected to the handle and to a stationary part of the engine for holding the electrodes normally in contact with each other; together with an arm projecting from the piston of the engine and adapted to strike the bent end of the working electrode or rock-bar and operate the same against the action of the spring at each reciprocation of said piston, for the purpose set forth.
4. The combination with an explosive-engine having a cylinder-head with an opening therein, a frame or casting B secured over said opening and presenting projections or housings b and b2, an insulated stationary electrode C mounted Within the housing b' to project Within the cylinder of the engine, a Working electrode C comprising a rock-bar bearing` in the other housing and presenting an end which projects within the cylinder and is bent at an angle and provided with a-beveled terminal which contacts with one side of the inner end of the stationary electrode, a handle G mounted on the outer end of the Working electrode or rock-bar, and a spring H connected to said handle and to a stationary part of the engine to hold the electrodes normally in contact with each other; together With an arm projecting from the piston of the engine to operate the working electrode against the action of the spring at each reciprocation of said piston, substantially as shown and for the purpose set forth.
