THOMAS B. SHRYOCK, OI. LAWRENCEBURG, KENTUCKY.
TIMER FOB INTERNAL- COMBUSTION ENGINES.
Specification of Letters Patent Patented Feb. 15, 1916.
Application filed Kai-ch27, 1915. Serial No. 17,395.
To all whom it may concern:
Be it known that I, THOMAS B. SHRYooK, a citizen of the United States of America, residing at Law'renceburg, in the county of Anderson and State of Kentucky, have invented new and useful Improvements in Timers for Internal-Combustion Engines, of which the following is a specification.
This invention relates to improvements in timing devices for the ignition circuits of internal combustion engines and has par ticular application to a manually controlled timer.
In carrying out the present invention, it is my purpose to provide a timer of the class described wherein the connections between the wires leading to the engine cylinders and the contacts of the timer will be incased so that such connections will be protected against dirt, water and other foreign substances.
It is also my purpose to improi e and simplify the general construction of timers of the type set forth and to provide a timer which will embody comparatively few parts and these so correlated and arranged as to reduce the possibility of derangement to a minimum.
-With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claim.
In the accompanying drawing, Figure 1 is a perspective view of a timerconstructed in accordance with the present invention. Fig. 2 is a sectional view through the timer. Fig. 3 is a similar view taken at right angles to Fig. 2.
Referring now to the drawing in detail, 1 designates the timer shaft of an internal combustion engine. Surrounding the shaft 1 adjacent to the upper or outer end thereof is a'disk 2 having the outer surface thereof at the periphery rabbeted as at 3. Fast to the outer end of the shaft 1 beyond the disk 2 is a collar 4% and radiating from the collar 4 is an arm 5 having the outer end thereof formed to provide a socket 6. The longitudinal axis of the socket 6 lies parallel with the axis of the shaft 1 and disposed within the socket G is a contact brush 7, while interposed between the inner end of the brush 7 and the inner end wall of'the socket 6 is a coiled expansion spring 8 normally urg ing the contact brush 7 out of the socket 6.
motor vehicle.
Disposed concentrically of the outer end of the shaft 1 is an annulus 9 having one edge seated within the rabbeted portion 3 of the disk 1 and the inner surface at the opposite end rabbeted as at 10 and disposed within the rabbeted portion 10 of the annulus 9 is a. circular disk 11 formed of insulating material and having the central portion thereof formed with an outwardly projecting protuberance 12 designed to accommodate the adjacent end of the shaft 1. Embedded in the inner face of .the disk 11 confronting the disk 2, are sector shaped contact plates 13 disposed concentrically of the axis of the shaft 1 and bearing against the inner faces of the plates 13 and rotatable from one to the other in regular order is the brush 7 held in friction engagement with the contact plates by means of the spring 8. The adjacent ends of the contact plates 13 are spaced apart and insulated from one another by the material of the disk 11. Connected with the respective plates 13 and projecting through the opposite side of the disk 11 are binding posts 14 and leading from the binding posts 1d are wires 15 terminally connected with the primary windings of the induction coil of the ignition system.
.In accordance with my present invention, a hood 16 is secured to the outer edge of the annulus 9 and incloses the binding posts 14, the disk 11 and the adjacent ends of the wires 15. This hood 16, in the present instance, is of frusto-conical formation and formed in the side wall thereof is an opening through which the wires 15 pass, while formed integral with the Walls of the opening and surrounding the wires 15 is a tube,
17 acting to protect the wires 15 at the opening in the hood.
Secured to the annulus 9 and radiating therefrom is an arm 18 connected through suitable rod and link mechanism with the spark lever on the steering wheel of the The disk 11 is fixed to the annulus 9 and when the latter is rotated in one direction under the action of the arm 18 the contact plates 13 are moved relatively to the brush 7, thereby advancing the time of the spark, while when the disk and annulus are moved in the reverse direction under the action of the arm 18 the time of the spark is retarded.
I claim:
a disk surrounding the timer shaft an annulus disposed conce'ntricaiiy of said shaft and restingupon said disk and capable of rotation relatively to said shaft and disk, an arm secured to said shaft and radiating therefrom, a contact brush earried by the outer end of said arm and disposed in a plane parallel with the shaft, a disk seated in the outer end of said annulus and adapted to more therewith contact plates on the inner surface of said disk adapted to be successively engaged by said brush in the rotation of the latter under the action of the timer shaft binding posts projecting through the opposite face of said and connected "with Wires leading raters a spark plugs of the engine, a hood secured 'rnoiaas B.
