Application filed August 7, 19l5.

To all 'whom it' may concern.'

Be it known 'that l, furrnun F. llli'nnni'rn, a citizen oi the United States, residingat lvlilwaukein in the county of Milwaukee and AState of ll'isconsin, have invented certain new and useful improvements in Magneto- Couplings, olf which the following is a speciiration, reibrenre being had to the aecompanying dra wing, forming a part thereof.

This invention relates to an adjustable n'iag'neto coupling, andthe objects of the invention are to provide a, simple, conveniently adjustable and accurate coupling; device Y.for connecting a, ninggneto with a, driving,` shaft through whirh power is transmitted to the magneto.

'lite/terringv to the drawings which accompany this specification and to rm a part hereol, which drawings illustrate an embodiment oi" this invention, and on which drawings the same reference characters are used to designate the same parts wherever they may appear in each of the several views, Figure l. is a.` front elevation of the coupling; Fig. 2. is a side elevation et the coupling; Fig. is a section through the couplingT on the'line (if-a. on li: l., looking' in the direotion iinlicated b v the arrows; Fig. l. is an enlarged elevation ol? one of the clutch members.

Referring to the drawings, the reference numeral 'l desimmtes a magneto, which is provided with the shaft 9i, and the reterence numeral 3 designates a driving' shaft which is coupled with the shaft ot the inngneto by the coupling.:v to be hereinafter described. The shaft 3 is rotated from a rotating` part of the engine in any Convenient or sl'iitable manner, as will be readily understood.q A yoke member l is seeured to shaft 2 or the magneto and consists of a hub member pro.

vided with arms extendingn therefrom onjopposite sides thereof end in line with each other. The yoke member #l is secured to a. leather disk 'i' by two bolts if and 6. rlhe leather disk 'i' is provided with a central aperture S for a nut (not sl'iown)l which re'- tains the yoke l on the magneto shart 2. Clutch members 9 and l0 are provided with screw bolts 1l and 1Q, or other suitable fasn tening means tor holdingthe clutch menibers in engagement with e. cireumterentinlly toothed member as for exemple the ordinary gear to be hereinafter described.

Specification of Letters ete'nt.

Patented Auf. 22, 1916.

Serial No. 442,317.

Each of 'the clutch members 9 and l0 is provided with a projecting lug, which ai* designated by the reference numerals 13 and it, respeetively, and these lugs are secured to the leather disk T by bolts l5 and 16, 'which engage with the leather disk 7 in a line sub stantially :it right angles with a line through the bolts 5 and The leather disk which Llorins the power transentting` connection be tween the clutch members J and l() :ind the yoke member Ll permits i'novenients of the Clutch inenibers O and l0 with respect to the yoke member d, the construction described forming a ilerihle coupling between the shnits .3 und rl`he opposing faces of the clutch member.` 9 and l0 are provided with substantially semi-cylindrical recesses provided with teeth i8 and 19 which are adapted to proj ect into the spaces between the teeth on the cirenn'iferentinlly 'toothed member 17, which is provided on the shaft lt is preferred to provide a plurality oit teeth on the Clutch members 9 and l0 to secure strength and to admit of tine adjustment. rlhe teeth on the circuniferentially toothed member l? are preferably ordinary gear teeth and the intermediate teeth on the clutch members i) and l0 are preferably ordinary .r teeth to mesh with the teeth on the circuinferentially toothed member l? but the end teeth on each of the clutch members 9 and l0 are so formed that the teeth on the Clutch membersl can be inserted into the spa ees betr en the teeth on the circumferentinlly toothed member iT, or withdrawn Jfrom the said spaces, by radial movements with respect' to the ciroumferentially toothed member l?, as will be readily understood from nn inspection of l. and t. ol the drs rings. By forming the end teeth on the rluteh members i) and l0, as described, more teeth can be provided on the clutch members to engage with the cireum'lferentially toothed member 17 than would otherwise be possible/ While retaining the desirable feature of en gaging the clutch teeth with the circumferentially toothed member, or disengnging themvtherefrom, by radial movements of the clutch members with respect to the circumrerentielly toothed member 17.

The construction described provides a flexible connection between the driving shaft and the magneto shaft 2 and enables the shaft 2 of the magneto to `be so Set with respeet to the driving shaft 3 that the ignition spark'or sparks will be timed eorreetlyfor theproper performance of the engine. An

the Correct relation between the magneto and the movable parts of the engine.

The leather disk 7,.,if of sullieient size, will be flexible enough so that the teeth on the clutch members can be disengaged from the space between the teeth on the eireum:

terentially toothed member` 17, but,r if the leather disk 7 should be so small that its flexibility would not permit the teeth on the elnteh members to be disengaged from between the teeth on the eheilmferentially toothed member i7 by bendingthe leather disk 7, the bolts l5 and 16 can be readily removed, thereby permitting the Clutch members 9 and l0 to be disengaged fromI the eircum'ferentially toothed member 17, and then the lea-ther disk 7, the yoke member fland the magneto shaft 2 can be turned in either direction, as hereinbetore explained, until the proper position is reached for the oor-- reet relation between the magneto and the movable parts of the engine. rllhe eluteh members can then be secured to the leather disk by the `bolts l5 and 16 and elamped upon the eireumferentially toothed member 17 by the screw bolts 11 and l2.

What is Claimed is:

l. An adjustable magneto coupling Comprising in combination a leather disk, a yoke member secured thereto, elutelrmembers secured to each other and secured to said leather disk in a line at substantially right a n gles with said yoke member, a driving sha i't provided with a eiremnferentially toothed member, the clutch members being provided with teeth adapted to engage with said eiroumterentially toothed member and being separable from each other radially of said eireumferentially toothed member.

2. An adjustable magneto coupling oomprising in combination a leather disk, a yoke member seemed thereto, clutch. members seollred to said leather disk in a line at sab-l stantially right angles to said yoke member, a driving shaft provided with a circumferlentially toothed member, said clutch members being each provided with a plurality of teeth adapted to engage Within the spaces between the teeth on said eiroumferentially toothed member, the teeth on each clutch member being so shaped that the Clutch members eau be engaged with the circumferentially toothed member or disengaged there from by radialv movements with respect,rv

thereto. f y' ln Witness whereof l hereto alibi my signature in presence of two Witnesses.
