UNITED STATES PATENT OFFICE.

ERNEST C. WILCOX, OF MERIDEN, CONNECTICUT, ASSIGNOB TO' THE CONNECTICUT TELEPHONE 8c ELECTRIC COMPANY, OF MERIDEN, CONNECTICUT, A CORPORATION OF CONNECTICUT.

Original application filed June 18, 1914,

paratus for electrical ignition systems, t e

object being to so construct such devices as to make them exceedingly compact and reliable, and so as to likewise make the various parts easily accessible forcleaning, re-

placement and repair.

- This is a division from my co-pending application Serial Number 845,834, filed June 18th,1914. v

In the accompanying drawings, Figure 1 is a vertical sectional view sho'win "certain parts in elevation. Fig. 2 is a pan view .with certain parts removed. Fig. 3 is a plan view with other parts removed.

1 represents a rotatable shaft. 2-2 are cams thereon.

3 is a housing having a central passage for the shaft 1.

4 is a condenser located in the lower part of the housing 3 and'preferably removable.

5 is a removable cover plate, while, 6 represents a spring locking ring seated in a groove in the inner'wall of the chamber in which the condenser is located, whereby the till plate 5 may be held in place. In the particular form shown, the lower .part of the housing or chamber in which the condenser is located is separated from the upper part of the housing by an intermediate partition in which may be provided two holes 77, whereby when it is desired to separate the parts, a suitable blunt tool may be inserted through the assages 7 to push the condenser out a or the plate 5 has been removed.

In the upper part of the housing is the so-called timer, as set forth in my original application from which this is a division, it is preferable that this timer be mounted as a uniton a removable carrier element 8, which has a central passage for vthe shaft 1. The cams 2.2 operate the interrupter parts. The interrupter includes the swinging breaker arm 11, carrying a contact point 10- arranged to coact with the fixed contact Specification of Letters Patent.

the rotary contact member24 mounted on the upper end of the-shaft 1, and the terminal segments 25-25 which are mounted in a suitable-housing 22. As the shaft revolves, the brush or contact 24 will encounter suecessively the terminal segments 25, andthe breaker arm 11 will be properly'actuatedto make and break the primary circuit, where by the high tension circuit which passes through the distributer will be closed at the proper time. The entire a paratus is rotatable relatively to the she I in the usual manner to advance or retard the spark.

20 is a removable cap for the housing 3. the housing 22 resting thereon. ,Theparts 22 and 3 may be connected in any suitable manner as by spring clips 29 carried by one part and engaging headed studs 30 carried by the other part.

In the particular form shown, the primary circuit is of the so-called grounded type instead of all metal type, although it is obvious that it is immaterial which one of these two methods of circuit is employed. In the drawings shown, one end of the rimary circuit is provided with the. terminal or binding post 15, theinner end of which is electrically connected with one of the interrupter terminal points,-the said terminal 15 being insulated from the housing 3. This terminal is likewise electrically connected with the condenser 4 throu' 'hthe medium of a brush 31, while the other side of the container is grounded by contact on the case or housing, the brush 31 being, of course, insulated from the housing.

present divisional application relates particularly to the construction and arrangement oi the condenser and associated parts. So far as I am aware, I am the first to employ the condenser in this particular combination of parts associating the same in direct conjunction with the timer or interrupter. Heretofore condensers have been placed at some relatively remote place, and have been electrically connected with the interrupter by correspondingly long wires, which have invited induction, condenser leakage and short-circuiting by faulty installation or worn. insulation. Furthermore,

by the old arrangement of such parts, I have shown that unnecessary labor has been required in making and safeguardin the connections. By my improvement. s own herein, the condenser is securely held within the same housing in which the interrupter mechanism is 'located,'whereby said parts may be electricallyv connected by an exceedin'gly short connecting means, such as for example the ,brush 31, all of which guaranteesthe adequate protection of the electrical connecting means and .reduces to the minimum all danger of short-circuiting, induction, condenser leakage, and other troubles incident to a paratus of thischaractor, due to remote e ectrical connection,

What I claim is:

In an ignition apparatus of the character described, a supporting shaft, a housing revolubly mounted thereon and supporte thereby, interrupter mechanism carried within said housing and protected thereby, a condenser also carried vglthin said housing and protected thereby, a terminal screw entered into one side of said housing and msulated. therefrom, an electric connection inside the housing from said terminal screw to one part of said interrupter, and a brush inside the housing connected between the terminal screw and one side of the coildenser, said connections being thereby all wholly protected by said housing.
