UNITED STATES JOHN HAYES, OF BELLE VER-NON, PENNSYLVANIA.

INTERNAL-COMBUSTION ENGINE.

Original application filed March 1, 1922, Serial No. 540,218. Divided and this application filed December 27, 1923.

To all whom t may concern Be it known that I, JOHN HAYES, a citizen of the United States, residing at Belle Vernon, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Internal-Coinbustion Engines, of which the following is a specification, reference being had to the accompanying drawings.

' This invention relates to certain improvements in internal combustion engines and it is primarily an object of thel invention to provide means wherein a make and break mechanism for the ignition system is caused to function as required.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved internal combustion engine whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more. convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be vdefinitely claimed.

In order that my invention maybe the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein 1# n Figure 1 is a view in top plan of an internal combustion engine constructed in accordance with an embodiment of my invention;

Figure 2 is an enlarged fragmentary sectional view taken substantially on the line 2--2 of Figure 1;

Figure 8 is a fragmentary sectional view taken substantially on the line 3-3 of Figure 1;

Figure t is an enlarged fragmentary sectional view taken substantially on the line 4 4 of Figure 1;

Figure 5 is a fragmentary view in side elevation of the engine as herein set forth.

As disclosed in the accompanying drawings, A denotes an engine block cast to provide two parallel series of vertically disposed cylinders C, the cylinders C of one series being of equal number with the cylinders in each series a multiple of two as is particularly described and illustrated in my copending application Serial No. 540,218 filed March 1, 1922, of which the present application is a division.

serial No. 683,035.

H denotes a head common to theJ cylinders C of both series and which is provided with the inlet ports 4 each of which is under control of a valve 6 having associated therewith an operating rod 8. The rod 8 is freely disposed through the head H and the outer or extended end portion thereof is secured toan end portion of a cross member 11, each cross lmember 11 having secured thereto the rods 8 associated with the valves 6 arranged in the corresponding cylinders C of both sets. Rotatably supported by the head H and extending longitudinally thereof above the members 11 is a cam shaft 27 provided with the cams 28 which engage the cross members 11 in proper timed sequence to effect the desired opening of the valves 6, said shaft 27 being in driven connection with the drive shaft of the motor (not shown).

Each of the members 11 has freely disposed therethrough the upstanding pins or shanks 30, each of which above the members 11 being provided with the head or enlargement 31. Interposed between each of the members 11 and head H and encircling the shanks 30 are the eXpansible members 32 herein disclosed as coiled springs which operate to constantly urge the valves 6 toward their seats. The head H has in communication with each of the cylinders C an opening in which is arranged a spark plug 34, the` operating circuit for which is normally open. Extending longitudinally of the head H adjacent each pair, of complementary cylinders C is a rock arm supported between a pair of upstanding lugs or bearings 36. The arm has a pair of inwardly directed arms 37 provided in their outer ends with the contact members 38.

Substantially midway its length each rock arm 35 is provided with an outstanding lug or arm 39 with which is engaged an eXtremity of a retractable member or coiled spring 40, the opposite. end portion of which is anchored, as at 411, to the head H. The retractable member or spring 40 serves to constantly rock the arm 35 in a direction to maintain the contact members 38 in an inoperative position. By the depression of the arms 87, the Contact members 38 are adapted to have requisite electrical connection with spark plugs so that the desired firing will be had.

Transversely opposed arms 35 operate in CII llO

unison and in ra. manner to cause simultaneous firing of the plugs v34 `associated with the cylinders C in which the pistons have unitary and corresponding movement, as set forth in my copendingapplication hereinbefore identified. In order to effect this simultaneous movement of the. arms 35 the central portions of said arms are provided with the inwardly directed lugs 42, Pivotally connected with these opposed lugs are the end portions of a cross member 43. Extending outwardly is an arm 44 continued by an upstanding extension or finger 45. This finger 45 is positioned directly below a cam 4G carried by the shaft 27 so that upon rotation of the shaft 27, he cross members 43 will be forced downwardly in proper timed sequence to close the ignition circuits.

From the foregoing description it is thought to be obvious that an internal combustion engine constructed in accordance with my invention is particularly weill-v adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles andspirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim l. In an internal combustion engine, a pair of spaced cylinders, an ignition means associated with the cylinders including a spark plug extending within each of the cylinders, the circuit for each of said plugs having a circuit closer interposed therein and comprising a stationary contact, a rock shat, a contact carried by the rock shaft for engagement Iwith the stationary contact upon movement of the rock shaft in one direction, an outstanding arm carried by the rock shaft, a retractable spring engaged with said arm for normally maintaining the contact 'carried by the rock shaft out of engagement with the stationary contact, each of the rock shafts being provided with an inwardly directed arm, a member connecting the inwardly directed arms of the rock shafts, and means engaging said member for int-ermittently moving the rock shafts to bring' the Contact members carried thereby into contacting relation with the stationarv contacts :2. In an internal combustion engine, an ignition means associated with the cylinders including a spark plug extending within 3. Inan internal combustion engine, a'

pair of spaced cylinders, an ignition means associated with the cylinders including a spark plug extending within each of the cylinders, the circuit for each of said plugs having a circuit closer interposed therein and comprising a stationary contact, a rock shaft, a contact carried by therock Ashaft for engagement with the stationary contact uponmovement of the rock shaft in one direction, means for normally maintaining the contact carried by the rock shaft out of engagement with the stationary contact, each of the rock'shafts being provided with an inwardly directed arm, a member connecting the inwardly directed arms of the rock shafts, and means engaging said member for intermittently moving the rock shafts to bring the contact members carried thereby into contacting relation with the stationary contacts.

4. In an internal combustion engine, a pair of spaced cylinders, an ignition means associated with the cylinders including a spark plug extending within each of the cylinders, the circuit for each of said plugs having a circuit closer interposed therein and comprising a stationary contact, a rock shaft, a contact carried by the rock shaft for engagement with the stationary contact upon movement of the rock shaft in one direction, means for normally maintaining the contact carried by the rock shaft out of engagement with the stationary contact, each of the rock shafts being providedwith aninwardly directed arm, al member connecting the inwardly directed arms of the rock shafts, an arm carried by the member terminating in an upstanding portion, and a driven cam contacting with said upstanding oortion to intermittently depress the mem er to bring the contact members carried by the rock shafts into contacting relation with the stationary contacts.

In testimony whereof I hereunto aiiix my signature.

JOHN HAYES.
