NORTH CHICAGO, ILLINOIS, .A CORPORATION OF. NEW YORK,
IGNITION MECHANISM-FOR INTERNAL-COMBUSTION rnwernns."
Be it known that I, ARTHUR O.- DADY, a citizen of the UnitedStates, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Ignition Mechanism for InternaLCombustion Engines, of which the following'is a'full, clear, concise, and exact description, reference being had to the accompanying drawings, forming, a part of this specification. 1 i
My invention relates to ignition mechanism for internal combustion engines, and w more particularly to ignition mechanism which includes a battery, a vibrator, ar-
ranged to cooperate with the battery circuit,
anda magneto, together with circuit connections whereby either the magneto or the battery togetherwith the vibrator may be employed for generating the current necessary for ignition in the engine cylinders.
The primary purpose of a system of this kind, which includes two sources'of current,
is to provide some means for generating an efficient spark at low engine speeds or at starting of the engine. It has been the practice to provide suitable switching mechanism in connection with the ignition circuit whereby it is possible to control theignition circuit to utilize the battery upon starting of the engine or at low running speeds thereof, and to cut out the battery and utilize the magneto at higher engine speeds.
The system of my invention incorporates the use of a timer which serves to determine the point in the engine cycle at which sparking occurs. When. the battery is furnishing the current necessary for 1gn1t1on,for,: n
other words, when the engine is running at low speed the timer is set to its retarded position so that sparking occurs at the proper point of the engine'cycle and when the mag neto is employed and the engine is running at high speed the timer is set to its advanced position. s c
It isvone of the objects of the present invention to provide an improved arrangement of mechanism for simultaneously controlling the ignition circuit and for controlling the advance and retard'of the timer so that when the battery circuit is included in the ignition system the timer will automatically assume its retarded position and when Specification of Letters Patent.

Application filed July 27, 1917. SerialNo. 183,042.
the battery circuit is cut out of the ignition system and the magneto current utilizedto furnish ignition the timer will automatically assume its advanced position.
In my co-pending application, Serial No. 183,043, filed July 27 1917 ,I have disclosed mechanism for simultaneously controlling the ignition circuit and timer which includes,
connections being provided between the switching device and the timer so that both may be operated in unison.
These and otherob ects of the present invention will be. pointed out more fully in connection with the accompanying drawings wherein,
Figure 1 is a diagrammatic circuit draw- 1ng showing the ignition system'of my 1n- Fig. 2 is a view showing the mechanism of my invention as it appears when in use;
Fig. 3. is an enlarged detail cross sectional view of the switching mechanism of my invention; and
Fig. 4 is an enlarged detail cross sectional view of the lower end of the switching rod shown in Fig. 3.
Similar characters of reference refer to similar parts throughout the several views.
Referring first to Fig. 2, I have shown at 5. a'portion of an automobile located at a point convenient to the operator, such, for example, as the instrument board, through which extends a'switch ,6 which is provided with an operating handle 7. The back of the board carries a vibrator 8 provided with binding posts shown at 9 and 10. The binding post 9 is connected through the conductor 11 with a battery 12, the other side of which is connected through the conductor'13 with-ground. The binding post 10 of the Y vibrator is connected through conductor 14:
with binding post :15of the switch 6. The
' magneto is shown-at 16 provided with a dis- ,tributer 17, the contacts of which terminate in the binding posts'1818 arranged to be connected with the several spark plugs of The interrupter is shown at 19 provided with a lever :i a 2 1 "t m-Q n c d t r0 gh the W r j Y with t eij n i thsfig wi l e-describe ,presently.

W hen it is desired to stop the motor the segment 52' is moved to the o position Qff whereby it connects the segment 49 with the segment 50 and thusto ground. The primary winding is then permanently grounded and is rendered inoperative.
The detail construction of the switch member 6 and the connection between the switch and the timer are most clearly illustrated in Figs. 3 and a. The switch member 6 comprises a metallic sleeve member 61 provided with the flanges 62 and63 to facilitate connection of the sleeve to the instrument board of an automobile. Mounted concentric with the sleeve 61, and attached thereto in any suitable manner, is a sleeve 64: made up of insulating material. The outer end of the sleeve 64: is attached to a metallic cou pling 50 which forms also a conductor segment. The coupling 50 is attached to the metallic tubing 65 which serves to cover and guide the wire 21 attached to the timer lever 20. Mounted for rectilinear movement within the sleeves 61' and 6a is a rod 66 carrying at its outer end a finger piece 7. The inner end of the rod 66 carries the conductor segment 52 which is insulated from the rod by the insulating washers, as 'most clearly shown in Fig. 4. The end of the rod is also provided with an aperture 68 which serves to provide means whereby the wire 21may be attached to the rod. The conductor segment 49 is embedded in the insulator sleeve 64, as is the conductor segment 51; The rod 66 is provided with a shoulder at 69 arranged to engage a washer 70 held in place by a coiled compression spring 71 interposed between it and the sleeve 6d. The arrangement of the spring mechanism just referred to is such that the rod 66 may be moved longitudinally within the sleeves without in any way compressing the spring 71 unless the rod is moved to a position whereby the segment 52 contacts with'the segment 50, whereupon the spring 71 is compressed and the rodreturned to-the position shown in Fig. 3 as soon as the finger piece 7 is released.
Having thus described my invention, what I claim as new and desire to secure" by Letters Patent of the United States is:
1. In anignition system for internal com- 'bustion engines the provision of a distributer, a timer, two separate sources of current, one for use at high engine speeds and the other for low engine speeds, a switch and circuit connections for rendering either one of said sources operable in the ignition system, said switch comprising a tubular casing having conductor and insulator segments disposed along its length, a switch member longitudinally movable in the casing for electrically connecting the conductor segments, and linkage connecting the switch member and the timer, whereby the latter is advanced and retarded upon operation of the switch.
