To fixedly secure the said'cam elements within the slots 24, I provide the washer 27,:"0nefa'ce of which is serrated as shownat 28 in Figure 14, which is adaptedito 4 cooperate with the serrations shown at29 on the inner faceofthe'timer cam-11, andthe nuts 30 which are threaded onjthe threaded shanks of said cam elements for securely looking said cam elements in the desired adjusted position. By reason of the elongated slotsv it will be. readily apparent that the said cam elements may be moved withinthe limits of said adjusted position within said slots. i L
The housing 3 vis'open at itsupper end'and is adapted to be closed bya suitable insulated cover or head designated generally. by the reference. character-31, said cover being provided with a'depending flange32, which is adapted to snugly fitwithin the housing 3.
'As shown in Figure 2 of the drawings,. the said cover is provided with a plurality of elongatedfslots 33, within which are adapted to be mounted the terminalconnecting sockets 34.
The said terminal connecting sockets are made of 'suitable insulated material, and havemounted therein the brass sleeve 35, the lower part of said sleeve being providedwitha threaded opening within which is adapted to be received the bolts 36, by means of which bolts thesaid sockets maybe rigidly secured to the covern31.

The center terminal 7, connecting socket 38,-it will be noted; is formed integral The extension shaft 1d is provided with an enlarged portion 19 which may be of any suitable form for facilitating the,
shaft intoithemain with the cover 31 and is also provided with the brass internal sleeve 39, the lower end of which is solid as shown at 40, and is provided at its bottom edge with a raceway l1, within which is mounted the ball bearing 42, said ball bearing being received within the raceway 41 and a depression 43 provided in the spring 23. It
A standard or post 47 is rigidly securedto the bottom wall of the housing '3, said standard having alreduced portion:- 48, upon lwhich'is mounted a sleeve of insulating material 49, said sleeve havlngimounted thereon theinterrupter arm. 50,- which is adapted-for pivotalmovement onv said sleeve; Theaassembly rof thei interrupter arm to the standard 47 is completed by means of an insulated washer 60, a metal washer -6l anda cotter pin 62 extendingsthrough an opening provided in the reduced'portionof the post 34. a The free end of the interrupter arm 50 has rigidly secured thereonuablocki 51 of in-: sulating material, which I may ibe. rigidly sejios cured thereto by means of the rivet 52, or :in
some other :suitable and well known mannen;
said block being adapted for engaging "the outer circumference of the timer. cam 11, upon which it is adapted to ride, and asshown in Figure 1 of the'drawings the said interrupter 55, which extends through an insulated threaded bushing 56, provided in the wallof the housing.
The contact55 has threaded thereona terminal 56, to which the lead 57 is connected Aynut 58 is provided on the inside 'of' the housing,
threaded on the contact '55l forfisecurely locking the same in" the desired adjustedposition i The contacts 55 and 54areso disposed-relative to each other as to be in contacting engagement with each otherwhen the block 51 engages the outer circumference of the timer cam lhand to be out of contacting,engagement witheach other when said. bloclg is in engagement with the heads of any of the cam elements 25.
it will be apparent that by adjusting the position of the cam'elements circumferentially on the housing 3, said handle beingprovide'd with a plurality of openings 65, whereby: the housing as a whole may befsecured in an advancedor retarded position.
' The operationof the device may be described aiw follo'wsz The interrupter arm 50 projects' into I the path of the cam elements 25, thespring 53 normally holding said-interrupter "arm in that position. The timer cam ll' isadapted to rotate with the Thus 54 and 55 are together, but as the timer cam 11 travels around with the shaft 5 the cam'elements 25 will be brought against the block 51 of the interrupter arm to force the latter about its pivot so as to draw the point 54 away from the point 55 and consequently break and interrupt the circuit. 'As the ignition circuit is controlled by the circuit through the points 54 and 55, it will be seen that the time of the ignition or the interval between successive explosionsmay be easily and accurately controlled by adjusting the cam elements in their respective slots, as hereinbefore more fully described.
It is believed that my invention, its mode of construction and operation and many of its advantages should be readily understood from the foregoing without further description, and should also be manifest that while a preferred embodimentof the invention hasbeen shown and described for illustrative purposes, the structural details are, nevertheless, capable of wide variation within the purview of my invention as defined in the appended claims.
