1913. Serial No. 804,850.

To (ZZZ whom it may concern:

Be it known that I, RICHARD VARLEY, a

citizenof the United States of America, re-

siding at Englewood, in the county of 36ergen and State of New Jersey, have invented new and useful lmprovementsin Ignition Apparatus, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, which.

form part of this specification.

in my application Serial No. 704,259, filed June 17, 1912, I disclose and claim an electrical system for autovehicles. The present application is a division of the subject matter thereof and more particularly relates'to the construction of the generator element therein shown and described. Its primary object is to provide an improved construction which permits of ready removal and replacement of the armature of the generator or magneto without the necessity of disassembling the collector rings and ignition contact or interrupter mechanism.

I also provide other features of construction, as will'be hereinafter more fully described and claimed.

' I will now describe my invention, reierring to the accompanying drawings, so that armature shaft, showing commutator and collector rings mounted thereon.

I In the above mentioned application Serial No. 704,259; Idisclosea system employing a generator adapted to deliver continuous and alternating current, the former for utilization by a work circuit and the latter for energizing an ignition circuit for exploding the combustible charges in the cylinders ofv an engine. However, I do not desire to limit the present invention to embodiment in a generator of any part cular type.

The frame 2 of the generator or magneto is provided with suitable bearings 3 and 4 in which is journaled anarmature 5 disposed between the poles 6 and 7 of the generator. This armature may be directly driven by the combustion engine through any suitable connection andjis shown as having a commutator 8 from which direct or continuous current may be taken for charging of a light or work circuit (not shown) and collector rings 9 and 10 from which alternating current may be taken for the purpose of energizing an ignition circuit (not shown). As shown in Fig. 4 the collector rings 9 and 10 are preferably carried by an armature shaft 11, being insulated therefrom by suitable insulation 12. The rings are preferably so disposed'on the shaft (as shown in Fig. 1) as to'be positionedoutside of the casing where they are readily accessible for connection with the ignition apparatus and are also of such diameter that the shaft may be readily slipped into or removed from the bearings ofthe generator frame without the necessity of disman- H tling or removing the rings therefrom. That is, the rings 9 and 10 are of a diameter equal to or less than the opening in the bearing 4 so that when it is desired to remove the armature or to place it inposition in assembling of the apparatus the collector rings may be readily passed through the bearing. This, as stated, also enables such construction as provides for simple connection of the collector brushes, andin Figs. 2, 3 and 4 I indicate a; desirable mannerof mounting in the collector brushes and interrupter or controlling mechanism of the ignition circuit. A front plate 13 of the armature frameis provided with a rotatively shiftable support or casing' 14 carried by which is a contact lever 15 and a coiiperative fixed contact 16 forming essentially the make and break or controller mechanism of an ignit16nciro uit.

An interrupter plate or cam 17for rocking or actuatingthe lever 15, is shown as fixedly carried by the armature shaft and, as shown in Fig. 4, may be formed integral with the outer collector ring 10 which may electrically connect with the contact lever 15. The casing l4. has a suitable radial arm 18, as shown in'Fig. 2, by which it may be ,rotatively shifted about"the cam 17 to obrangem'ent.

tain spark adjustment, in a well known manner, and holding the casing in position (see Fig. 1) is a spring arm 19 pivotally carried by a post .20projecting from the generator frame, said post being provided with a nut or .clamping arrangement 21 which serves to hold the arm in position.

At the'top of the casingis mounted a block of insulation 22 carrying collector brushes 23'and 24 which extend into the casing preferably at such angles as to conveniently o sition them atthe top thereof. .The brus 'es themselves are mounted in conductive sleeves 25 threaded into the block 22, which sleeves in turn may carry .the usual split terminals or spring posts 26; these posts being screw threaded intothe sleeves so that besides being detachable, they may formad- 'justin urge t e brushes a ainst the collector rings.

means for springs 27 which serve to It will be seen hat the ignition contact mechanism and collector brushes may be readily removed intact with the casing from the generator frame, when it is desired to inspect, adjust, or clean the apparatus, and

may be replaced with the'same facility withoutdisturbing or deranging the parts." .The

parts are also confined within a smallfcompact space and'do not project or extend obtrusively so as to be liableto injury or de- While I have shown and described a certain form of construction, I donot-desire to limit myself thereto, as the same may be embodied in different apparatus without departing from the broad idea claimed.

Having thus described my invention, what I claim and desire to secure by Letters Pat- .ent is:
