SPARKING IGNITER.

Specification of Letters Patent,

Patented June 26, 1906.

To (1U 1071/0771, it' may concern:

Be it known that I, CHARLES M. HUEY, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Sparking Igniters, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

My invention relates to electrical ignition devices, and particularly to that class of such devices in which the parts thereof are readily replaceable and also interchangeable upon different machines; and it consists of 'means hereinafter fully described.

'The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used. A

In said annexed drawings, Fi re 1 represents a central vertical sectionalliriew of my improved igniter. Fig.- 2 represents a horizontal section of the same, taken upon the Fi 3 represents a front view o f the armaturplate; and Fig. 4' represents a horizontal section taken upon the plane indicated by the line 4 4, Fig. 1.

In my improved igniter an outer protecting gas-proof casing A is provided, having a hexagonal-shaped cover A', adapted to be dirt and gas proof and yet allow of easy access to the working parts of the device. The gas-tight casing enables the igniter to be used under water and in similar submer ed places. vA core'or spool Bis containedwit in the casing, is internally screw-threaded at its lower en and adapted to receive an externally screw-threaded portion A3 of a plug A2, which latter is screwed into the cylinderhead, as shown. The plug A2 has a central bore c', which receives a vertically-movable drill-rod or'bron'ze rod C, which projects Vinto the cylinder from such plug A2 and extends centrally up through the core B and projects from the same through a plate C, suitably secured at the top thereof, as shown. This drill-rod C is preferably made of non-magnetic material, so that it will not grip when 'the core B is magnetized, and is adjustable Within the core at c, the adjustability being secured by breaking the rod at c into two parts and threading one part intov the other. The inner part may be threaded into the other part a greater or less amount, as is desired, from the outside of the core by operating the upper part of the drill-rod after breaking its connection with a rocker-arm c2, to be hereinafter more fully described. A

.suitable spring c is provided between a shoulder upon one of the parts of the drill-rod C at c and the top of the plug A2, which spring operates to normally hold the drill-rod C in its u permost position.

Suitab y pivoted to the top ofthe drill-rod C is a rocker-arm c2, comprising a right-angular piece pivotally mounted within its right angle at csupon the plate C" and receiving at its top a pin D, which is screw-threaded at its outer .end for a urpose hereinafter described. A spring d) upon the pinD, disposed between the headl of the same and the rocker-arm c2, acts as a cushion to take up any jar that might be occasioned when the device is operated, as will be hereinafter fully described. The plate C is provided with two upwardly-projecting ears c4, which receive a pin passing through the rocker-arm c2.at c3 to secure the rocker-arm pivotally to'A the plate C. An armature E is securely fas' tened to the core B by short pins or screws e, passin through suitable ears e', and is normally eld out of contact'with the core B by means of a wire e3, passing around the core B, as shown in Fig. 2, and comprising springs e2. These springs e are ends of the wire epass around pins e and extend rearwardly along the lateral ed es ofthe armature E, and at their tops are lent forwardly and crooked'so asto engage said ylateraledges ofthe armature, exert a pressure thereon, and normally hold same out of contact with the core B. These springs e2 are made of phosphor-bronze or other suitable non-magnetic material which will withstand a great heat. The springs ma ,however, be made of magnetic material, if esired, and suitable nonmagnetic Wash ers provided on the pins e e.

The length of the springs e2 and the amount With vwhich they are bent forwardly and crooked maybe varied in order to vary the force which they exert on the armature E.

The springs e exactly center the armature E relatively .to the core B and enable it to strike said core correctly when attracted thereby. The lower part of the armature E is held only a short distance comparatively from the core B,is tirst attracted by sa'd core, and then assists in pulling the upper part in toward the core. The armature is positioned a comparatively large distance vertically from the flange b of the core B in order that said lange may not attract it and cause it to hang, so that it would not be easily and readily pulled inwardly at the top. The main portion of the armature is of substantially the same height as the core B and at its top is provided with an upwardly-extending tongue je", which has a threaded bore adapted to receive the threaded end of the pin D,`which'rnay be threaded into the armature a greater' or less amount to vary the distance at which the armature is held away from the core B. l l

The drill-rod C receives at its lower end a transversely -locatedl conductor F, which passes through a small ring f, connectedt'o the drill-rod, within which it is loosely upported and in which it has' a limited sli ing movemeht when the drill-rod C is operated, thereby ehahlii'ig the conductor Epto move relatively to the rod C. This relative movenieht 'of the conductor F and rod C ehables the contact-electrodes f f2 (hereinafter described) to be kept ah'nernent 'and prevents their beingv thrown around at an angle rto each 'other wheh the rod C is operated. The conductor F-is provided at one end with a'. suitable contact electrode j", adapted yto form one of the electrodes between which the spark passes to cause the desired inition. At, its other end said arm F is pivote: in the outer end of a conductor F', screwed into the lug A2. The plug A? isprovided with a arge bore K, laterally of its center and eX- tending up through ythe main portion of the saine. This bore is filled with suitable insu;- lating material 7c, which has a small central bore le', as shown; The lower flange b of the core B is provided with a similar bore K/ laterally of its center and also laterally of the bore K. Suitable insulation k2 with a bore lc'is provided for the bore K similarly to the bore K. The bottom of the spool-flange l) and the top of'the main portion of the plug A2 are provided with similar registering aniru'lar coves l1 b2, lilled with suitable insulatklo from the winding of the core B. 'lhe central bore l" in the insulating material K is enlarged at itslower portion and receives a conductor F2, provided at its outer end with a contact-electrodefz, adapted to form the second ot' the electrodes, between which the spark passes. The conducting-wire lvlis connected to the conductor F2. The insulating-bushings 7c4 t' are sernicircular, grooved in their lateral centers, and reversely placed with respect to each other, so as to form an annular tubular bushing in the registering coves b b2. Within the grooves in the littoral ceiiters yof this bushing are provided thin juxtaposed vcopper rings le k7, as shown. The conductin'gwires le and k1" are connected to the rihgs k7 7c, respectively, and the current passes from one ring to the other-at any of the contacting points upon their juxtaposed surfaces. Said rings are completely surrounded by the are nular cylinder of insulating material frine'd by the insulation 764 and 7c3' and thereby all short-circuiting is 'eli'ec'tively prevented. A binding-post a is secured to' the caslhg A 'aiid connected with one of the poles of the souree of electricity. ,I

The operation of the device, which `will be easily understood from the foregoing' de# scription, is as follows: The lcore B is magnetized by the current passing 'around it in the winding, as shown, and attracts the armature E, the upper end of which carriles '1n'- wardly with it the pin' D, which aetuates the lower end of the arm c2 downwardly and causes the drill -rod C to carry the contact-electrode f away from contact-electrode f2 and produces a spark; This breaks the eirfc'iilt, which causes the core t'o release the armature, and the contact-electrodesf and2 are aga-ih brought im@ jumps-sean. a will se read that the spring d protects the device from ahy jar when the armature lies back to its noi"- mally outer position away from the core B; The s 'arki'ng is very rapid, there being produce about seventy-rive sparks a second, producing4 a substantiall 'cotini'o'hs spark about the si'z'e oi an or inary matcheheald; It will be noted that there are three ways el adjusting the armature so as to secure' vaniation' in the strength and duration of the spark, which are respectively the adjustable joint at c on the drill-rod C, the adjustability ofthe outer end of the pin D within the arma'- ture E, and the variation of the tension of the springs e2. The adj ustability of the rod C also enables the contact-electrodes f and f 2 to be drawn more closely together when they have become worn. By means of this plurality of adjustments the force withv which the armature E is held'away from the core B can be -nicely and accurately secured as is desired, it being readily understood that the farther the armature is held normally from the core the larger will be the spark 'that is obtained. .The center of the three holes in the bottom of IOC in a the plu which receive the conductor F', the drill-ro C, and the conductor F2 ,lie in a straight line in the same vertical plane, thereby producing a moreefective device than those devices in which one of the outer holes necessarily lies off the center to allow for-the operation of the eccentric hammers which are usually utilized. By providing the annular copper disks k k7 an accurate 'adjustment orizontal plane does not necessaril have to be effected between the screw-threa ed portions of the plug A2 and the core B, for contact at a plurality of points will always be effected between these disks, because of the large contacting area with which they are provided, and it will make no diiference in what vertical plane any part of either of the disks falls when the core B and the plug A2 have been accurately screwed together, for there will always be plenty of contact between the disks to satisfactorily conduct the current.

All of the parts of my device are interchangeable and can be used upon diiierent machines to which it is desired to attach them. Also each part is easy of access, so that if it becomes worn or if for any other reason it is desired to replace it with a new part this may be done with very little difficulty. EX- terior to the igniter there is shown a diagram of one suitable form of a circuit making and breaking device, as represented at H.

Because of the few parts of the device which it is necessary to operate in order to produce a spark and because of the ease with which these parts are actuated a decidedly less amperage is required than in other def vices with which I am acquainted, and the saving of the cost of two or three batteries is effected.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, 'provided the means stated by any'of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention- 1. In a sparking igniter, the combination of a casing; a core; an armature; a plug connecting the core and the cylinder-head; a contact-electrode secured to said plug and insulated therr rom; circuit connections; a rod carrying a second contact-electrode; means connecting said rod and one end of said armature; and a spring intermediate of said cere and the other end of said armature and constructed to bear against the lateral ed es of the latter, said spring thus centerin e armature relatively to the core and .ho din the same normally out of contact with sai core.

2. 1n a sparking igniter, the combination of a casing; a core an armature; a plug connecting the core and a cylinder-head; a coritact-electrode secured to said plug; circuit connections; a twoiece rod carrying a second contact-electro e and three in pend'- ent groups of means Jfor adjusting the force with which the armature is held out of contact with the core7V comprising, iirst, an adjustable spring intermediate of said armature and core; secondly, a pin having threaded engagement with the armature and connected to said rod; 'and thirdly, means for adiustmg one piece of said rod within the other piece thus making the rods length capable of being varied. e

3. In aV sparking igniter, the combination of a casing; a core; an armature; a plug connectingv the core and a cylinder-head; a contact-electrode secured to said plugpcircuit p connections; a rod comprising two'pieces-one adjustable with the other, thus making the rods length capable of being varied; a second contact-electrode carried by said rod; a rocker-arm pivoted to the core and connected to said rodg'a pin threaded into the armature and connecting the latter with. said rocker-'arm 3 a spring upon said rod and vadapted to bearagainst one piece of' the same to hold the armature out of contact with the core; and a second spring passing around the core, and provided with two bent ends adapt-v ed to bear a ainst the lateral edgesiof the ,armature, sai second spring thus centering the latter relatively to the core and holding the same normally out of contact with the core.
