Specification of Letters Patent.
Patented Nov. 20, 1906.-
I Application filed ianuar 'aisoe. SerialNo.295.274.
improvements in igniters for explosive-en gine's. Its object'is to provide an efficient and simple igniter and maintain it in oper,
ative condition.
It is well known that in theuse of igniters which have a bar extending through the cylinder-head into the interior of the cylinder and surrounded, as such bar must be, by insulating material there is a tendency for the materials found in the interior of the cylin-.
der, and especially for carbon, the result of the combustion there taking place, to collect upon this insulating material and make a deposit thereon and in connection therewith, which will establish a circuit between the igniter-bar and other adjacent parts of the mechanism,- so as to prevent the formation of the desired spark at the proper place, and to avoid this difficulty is the more special object of my invention. This object I accomplish by the mechanism shown in the accompanying drawings, in which Figure 1 is a vertical cross-section of my device ready for insertion into the cylinderhead, the cross-section being taken on'line :c as. of Fig. 2. Fig. 2 is a sideplan ofthe same parts, a portion being broken away to 5 is the igniter-bar, made of any suitable material and extends from the outside of the cylinder-head through into the interior. It
is preferably threaded upon both ends, as shown.
6- is a binding-nut adapted to clamp down the circuit-wire, the upper end of the bar 5 thereof serving as a binding-post.
1 is an insulating-sleeve, made'from porcelain or other suitable material, wholly surrounding the igniter-bar. At its upper end it is provided with a cap 7, making engages ment withthe screw-thread of the igniterbar and holding the sleeve from movement in that direction. At its lower end it is provided with a suitable depression to receive the threaded nut 8 which is screwed up against the resulting shoulders and holds the sleeve from movement in that direction. 2 is a metal sleeve surrounding this insulatingsleeve, having the outward projection shown and having the external screw-thread 1 1 and having at the lower end the-bead 14.
3 is a lock-nut, and 4 represents an external thread on a portion of'the sleeve 2 and an internal thread on the lock-nut 3. This sleeve 2and this nut 3 are provided with or constitute shoulders which engage with corresponding shoulders on the insulating-sleeve 1, and thereby, holdit from motion in either to it.
10 is a washer or disk, closing the lower end of sleeve 2, held in position by the beading 14 afind having the central opening shown in is a loose sleeve or ferrule surrounding the lower part of the insulating-sleeve 1. It is prevented from moving upward very far by the shoulder shown on sleeve 1, and it is prevented from falling down out of position by the washer 10. It is not connected either with the insulating-sleeve within it or With the metal sleeve outside of it, but'is free to vibrate and shake and rap against the adjacent parts.
13 1 3 are notches or open. spaces in the.
' direction with reference to the parts external lower part of the sleeve to permit the gas more freely to enter within the same, and.
12 12 are notches or corrugations upon the upper edgeof the sleeve, wherebyit may more efficiently scrape the insulating-surface I of the sleeve 1.
15'represents notches or. openings in the lower edge of sleeve 2 to permit the gas more freely to enter the interior of the sleeve.
device can be assembled without difficulty into the form shown in Fig. 1, making the device complete. It is then screwed down into the ordinary screw-threaded opening in the cylinder-head, the thread 11 engaging It is evident that the various parts of my" with the internal thread upon the opening in the cylinder-head, and it is screwed down tightly until the projecting portion of sleeve.
2 engages with the external face of the cylinder-head. Then when the electric current is passed through the igniter-bar a jump-spark will be formed between the lower end of the igniter-bar and the nearest portion of the washer 10, and this spark being properly timed with reference to the presence of exlosive gas in the cylinder an explosion will I ollow. Evidently this explosive as, being under considerable pressure, Will 11 all the open spaces within the sleeve 2 and inside the cylinder, and the explosion will cause a great shock and vibration at this point. Thereby the loose sleeve 9 will be jarred and shaken against and upon the parts adjacent to it on both sides and above and below, and it will scrape or knock or jar loose the carbon and other deposits that otherwise would form. There will be a repetition of this jarring and shaking'and knocking at "every explosion; and it Will be found impossible for any considerable deposit to form or for any short circuit to result.
Having thus described my invention, What I claim to have invented, and desire to secure by Letters Patent, is-
An igniter for explosive-engines, comprising an ignited-bar, an insulating-sleeve, a jarring member, and means for loosely retaining the jarring member in continual proximity to the adjacent parts.
I In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
