' GA ENGmE' .SPARKER.

To aZZ whom, it may concern.-

Be a known that I, STEPHEN A. HAS

eRoUc'K, acitizen o'f-the United States, reslding at Yonkers, in the county of- Westchester, State of 'Ne w York, have invented certain new and useful Im rovemehts in Gas- Myinvention relates to particularly to an'igniter or sparker.

. The invention consists in theimprovements hereinafter described in igniters of the make-and-break type, including able and 'stationaig eectrode an operating means W a mop, suitable ereby the. contact members are normally held a art, but are momensame to form an arc of-large and efiective proportions, said arc/being produced and ruptured so quickly that there is very little:

destructive action on. the contact-points,

such as usually results where the separation --is relatively slow. 3

ism.. Fig. 2 is-a The object of myinven tion is to construct the said s arker so that 'it will be sim 10,

effective, urable, and easilyadjusted. he construction is also such that the moment of the spark may be timed, so as to give an early or late ignition to the gas.

' In the drawings, Fi e 1 represents the lan view of the head 0 a gasi-engine'cylinder tted with my iproved sparking mechana entary view thereof,

partly in vertical sect on and artly in'elevation. Fig. 3 is a vertical'section'throu h the spark-plug and the associated arts. ig. 4

5 is a stem carried by the lug 2 and in turn carrying at its inner end astationary electrode or contact member 6. The stem 5 and the contact member 6 are insulated from the plug, 'as shown. at 61.

.7 is a movable electrode or contact member, the same being in the form shown an arm eccentrically mountedon a stem 8, so as to have a rocking movement in the plug 2.

A-s'pring 9 serves to hold the inner end of the stem 8 firmly against the inner end of the plug 2 to aid in forming a gas-tight connec- 11 is what I s all tern-1 a hammer-arm, the same being carried by Ca rock-shaft 12, which in the preferable form hasan oscillating bearing 13 in the head 1. The ends of the arms 10 and 11 'overla each other and under normal conditions ta e a-flat bearing, as best seen in Fig. 1. contact members 6 7 are spaced apart.

- 14 is a spring which is secured at one end to a suitable extensionor stud 15 on hammer-arm 1 1 and at the other end to a suitable extension or stud 16, carried by the anvilarm 10.' The strain of this spring 14 extends across and preferably diagonally across the bearing-line of the overlapped ends of the 1-0 is what I shall term an anvil-arm, (which is suitably secured to .the outer end of the stem 8 and roje'cts laterally therefrom. tarily and intermittent y, actuatedso as to close the circuit and then quicklybreak the In this position the arms 10 and'11,-and hence no matter which way the hammer-arm 11 is swung said spring 14 will tend to restore said arms to the nor: mal position. (Indicated in Fig. l.)

sion or arm17. 18 may represent the camshaft of the engine. whichrotates therewith and is arranged to in-' 'termittently and'momentarily engage with 23 in an operating-slide 24, which is employed in the'manner hereinafter described to shift the position of the rock-shaft to produce an early or a late spark.

25 is a diagonal slot in the slide 24, into The rock-shaft 12 isprovided with a lateral exten- 19 is a finger thereon slot 21 in the engine-frame 22, while another portion of said collar 20'projects into a slot which a pin 26' may project. The pin 26 is a stationarypin mounted on the frame 22, so thatwhen the side 24 is shifted lon 'tudinally the said pin 26, acting in the s t 25, will necessarily impart a forward or rear- Ward movement to the slide 24, and hence because a part of the collar projects into the slot 23 the said movement will shift the said collar 20 forward or backward in the slot 21. -Thus the rock-shaft 12 will be swung on its bearing 13.slightly and the contact-arm 17 willbe moved so as to be engagedearlier or later by theop'erating-finger 19. .In this simple manner an early or a late spark maybe produced. A thumb-nut '27 ay be mountedon the stud 26 by means of which the slide 24 may be set in any desired position.

28 is an adjusting-screw which may be carried by one end of the plug 2. Y The inner end of-this screw may bear against one of the studs so that when the nuts 4 4 are loosened the said plug may be rotatedireadily and accurately to eiiect the desired adjustment and position of the electrodes and incidentally the position of the anvil-arm 10 relatively to the position of the'hammerarm 11 when thelatter is retr'acted-for example, to the position indicated in Fig. 4. 4 A nut 29 may be 'mountedon the screw 28 to set it in the desired position. To cause the from the foregoing description will be readily understood. The rotation of the part 118 carries the finger 19 in a circular path. The finger 17 projects intothis pathan'd is engaged intermittently and. momentarily by engagement rocks the the finger .19.v This shaft 12 and retracts thehammer-arm 11 to the position indicated in Fig. 4. The first part of this movement removes the said hammer-arms from the position indicated in Fig. 1, whereupon the arm 10 follows until'the contact-points engage, checking the further movement of'said arm. Now, in order to get an effective blowand a; uick arc the hammer-arm is retracted still urther, so as to become free from the end of the anvil-arm. (See Fig. 4.) This further movement puts the spring 14 under still more'tension, so that.

"when the finger 19 trees the arm 17 said spring by its retractivo action will quickly draw the hammer-arm back to cause it to impart a quick sharp blow to the anvil-arm,

ends of the arms 10 and 11, I

"rupturing the circuit instantaiieously and producing a large and effective spark. The

spring 14 then'causes thearms 10 11 to resume their normal 1) until the finger 19 shall again engage the arm 17. It will be observed that but one positions (shown in Fig. Y 7 I spring is employed to produce: all of these I functions: For example, it first holds the bperativemembers in such a position that the contact-points are held apart and the arm 17 in the proper position to be engaged It next draws the contactpoints into engagement when the hammer is retracted, and it finally stores the necessary force in thehammer-arm to -.ru ture the eir cuit and produce the spark. T e oscillatlng bearing 13 is located so near the upper end of the rock-shaft 12 that: the movement at thelower end of the rock-shaft necessary to roduce a substantial chapg'e in the timing 0 the spark does not disturb the position of the hammer-arm 11 relatively to the anvil-arm 10. It is. obvious. that this invention is ap-;

plicable to any formotgas-engine. The.ar-.-

rangement herein shown indicates that the part 18 revolves clockwise. It is obvious to .any mechanic that the parts could be reversed so that the travel could be in theopposite direction. Even assuming that with the arrangement illustrated thQ part 18 should be revolved in a direction opposite to that indicated by,the arrow it will not injure 1 the igniter in any way, but;will simply throw the hammer-arm 11 in the opposite direction:

from that'inidi cated. This, however, would would not occur, would restore the parts to their normal position. I 1

The contact members are only conventionnot result in any harm,-for although the are nevertheless thespring 14 ally shown. Obviouslythe usual special points might be added thereto. Should'the contact-points wear down so as to vary the adjustment-ofthe parts and allow of too --lit I tle separation of said arms at the back position, it is merely block 2 to a sufiicient extent tobring the stationary contact member nearer'to the movable member, which movement also shifts the angular position of the stem 8-and anvil-'- q. necessary to rotate the arm 10., so that the hammer-arm 11 will upon.

the limit of its retractive movement become freed or spaced apart from the end of the anv1larm a suflicient distance toinsure the sharp quick blow essential tothe instantaneous rupturing of the circuit.
