Specification of Letters Patent.

Application filed February 20, 1912. Serial No. 678,952. 7

Patented June 18, 1912.

To all whom, it may concern Be it known that I, TIDEMAND OPSAHL, (born in Norway, and who has declared his intention of becoming a citizen of the United States) residing at Fillmore, in the county of Ventura, State of California, have invented new and useful Improvements in Mechanical ll lovemcnts, of which the following is a specification.

I have shown my device as it would be applied to the magneto shaft of an explosion engine for the purpose of advancing or retarding the sparking thereof, but I do not limit myself to such application.

Heretofore, in the operation of explosion engines, when it was desired to advance or retard the sparking thereof, it was necessary to oscillate the breaker boX containing the contact points and their connecting wires, which often resulted in wearing off the insulation from the wires, loosening the wires from the posts and bending the contact points out of alinement, thus causing the engine to frequently misfire.

The object of my invention is to provide simple and eflicient means for advancing or retarding the sparking of an explosion engine, which will not disturb the wires or contact, and which will be easy to operate and positive in action. I accomplish this object by means of the device described herein and illustrated in the accompanying drawings in which:

Figure 1 is a view in elevation of my in vention. Fig. 2 is a longitudinal section taken on the line 2-2 of Fig. 1. Fig. 3 is a cross section on the line 3-3 of Fig. 1.

In the drawings 5 and 6 are the driving and driven shafts respectively, the ends of which abut together. A coupling sleeve 7 surrounds the abuttlng ends of said shafts. A pin 8 rigidly secures said sleeve to shaft 6. Surrounding sleeve 7 and slidable thereon is an adjusting sleeve 9. Said adjusting sleeve has an enlarged portion 10, preferably at one end, in which is out a groove 11 for the reception of an operating collar 12. Collar 12 is preferably made in halves and is connected together by screws or other fastening means passing through lugs 12. An operating lever 13, the lower end only of which is shown, is pivotally connected to collar 12 and provides means for operating the adjusting sleeve. A pin 15 is rigidly sesaid coupling sleeve,

cured in and near oneend of sleeve 7 and extends upwardly into a diagonal slot or way 16 in sleeve 9.

In shaft 5 near the abutting end thereof is rigidly secured a pin 17 which extends downwardly through a transverse slot 18 in sleeve 7 and thence into a longitudinal slot or guide way 19 cut in the sleeve 9. Slots 18 and 19 are shown in dotted lines in Fig. 1.

In the operation of my device with the parts in the position shown in the drawings, should it be desired to advance the spark of the engine the adjusting sleeve is moved in the direction of the arrow in Fig. 2, which causes it to slide to the right upon sleeve 7, thereby advancing the application of the driving power to the driven shaft. As the driven shaft carries the contacts which engage the terminals of the breaker box the spark is thereby advanced. The reverse movement of sleeve 9 will, in like manner retard the spark.

Having described my invention what I claim is:

1. A mechanical movement comprising a driven shaft; a coupling sleeve secured to the driven shaft and projecting beyond the end thereof, said sleeve having a transverse slot in its projecting portion; a driving shaft projecting into said coupling sleeve in alinement with the driven shaft; an adjusting sleeve slidably mounted upon said coupling sleeve, said adjusting sleeve having a longitudinal slot crossing the transverse slot of the coupling sleeve, and a diagonal slot opposite the longitudinal slot; a pin mounted in the driving shaft and projecting into the transverse slot of the coupling sleeve and the longitudinal slotof the adjusting sleeve; and means to shift the adjusting sleeve upon the coupling sleeve whereby the power of the driving shaft may be applied to the driven shaft at different points.

2. A mechanical movement comprising a driving and a driven shaft in alinement; a coupling sleeve secured upon one of said shafts and surrounding the end of the other shaft, said sleeve having a slot therein; an adjusting sleeve mounted and slidable on said adjusting sleeve having a slot therein at right angles to the slot in the coupling sleeve and crossing the same, and another-slot diagonal thereto; a

pin mounted in the shaft not secured to the have hereunto subscribed my name this 10th coupling sleeve and passing through said day of February, 1912.

slots; a pin mounted in the coupling sleeve and projecting into the diagonal slot of the TIDEMAND OPSAHL' 5 adjusting sleeve; and means to move the ad- WVitnesses: justing sleeve. G. E. HARPHAM,
