To all wwm it may concern Be it known that l, EDWIN Gr. Suona, a citizen of the United. States, resident ot Minneapolis, county ot Hennepin, State ot Minnesota, have invented certain new and useful llmprovements in Centrifugal Speed- Regulators, ot which. the following is a specification.

'llhe primary object of my invention is to provide a centrifugal speed regulator wherein the speed ot the driven member will vary in a greatery proportion than the rgariation in the speed ot the driving mem- A further object is to provide an improved controlling mechanism operated by the .driving member t'orl controlling the speed of the driven member'.

It further object is to provide a mechanism which will be simple and compact in construction and highly etlicient 1n the economical transmission ot power.

My inventionconsists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

ln the accompanying drawings forming part ot this specitication, Figure 1 is a plan sectional view on the line. z-z ot Fig. t, Fig. 2 isa transverse sectional view on the line -w ot' Fig. 1, Fig. 3 is a similar view, showing another position of the parts, Fig. t is a transverse sectional view on the line g/-y ot Fig. l., Figs. 5, 6, 7, 8, 9 and 10 are diagrammatic views illustrating the successive positions ot the parts shown in Figs. 2 and 3 in the operation ot the gearing, Fig. 11 is a plan sectional view ot a moditied construction.

ln the drawing, '2 represents a trame having a housing 3 thereon to which a casing t is secured by suitable means, such as bolts 5. t stationary ringV 6 is mounted in the housing 2 and a revolving ring 't' has-bearing balls 8 on the stationary rin and encircles a hub 9 and revolves therewith on said bearing, a suitable acltin vl beingo interposed between said ub and the wal ot the housing 3 through which. said hub projects. .t torltll is termed on the outer end ot said hub, terminating in a hub l2 having means tor connection with a driving member, such as a collar t3. d pin lt is centrally mounted in the hub 9 and rojects outwardly beyond the same mi is preterably tapped into the hubld. .t pinion is loosely mounted on said pin between the arms 16 of the fork 11. A pin 17 is mounted inthe hub 9 and has a s( uared end18 to receive an arm 19 provided with yteeth 20 to mesh with the pinion 15, said arm having a weighted end 2l. and a set screw 22 to bear on one of the fork arms 16, being held in engagement therewith `by a spring 23. @n the other side ot thepinionis an arm 2t mounted on the' outer squared end of a crank 25 which has one end journaled iny the hub 9. 'llhe arm 2t has teeth meshing with the teeth ot the pinion vand a weighted end and spring corresponding to those described with refer. ence to the arm 19. 'llhe movement ot the arm 19 is transmitted through the pinion 15 tothe arm 271i and both ot' the arms will be thrown outward `by centrifugal torce and the cranlx 25 will be rocked tor the purpose hereinafter described. l l

'llhe inner end oit the crank 25 is normally concentric with the hub l9 and has bearing rollers 26 tor a ring 27 which'encircles thisV section. Un this ring friction shoes 31 are `mounted, each having a recess 32 therein decreasing in depth trom one end to the other, as usual in triction shoes ot this'type and provided with a roller 33 and a compression spring 34, the roller being adapted to grip t 1e triction ring and lock the shoe temporarily thereon. ll preter to ot these shoes, there being our in number shown in this case, but a greater or less number may be rovided, as occasion may require. Fach s oe is provided with an arm 35 pivoted thereon and having a hub 36 at its inner end that is journaled in bearings in the ring 2l' and is tree to turn therein, the arms being curved slightly` as indicated in Fig. Q. Flvidently, as the crank 2h revolves with the huh 9, its inner end will remain concentric with the driving member, but it said inner end is roclted by the shitting ot position ot the arm 2l the rovide a seriesI anl arms 35 will be actuated, and their shoes a dange 36 that is tormed integrally with lliltl abei'elgearifl loosely mounted On thesliaft fiOpi'ovided with a collar. 41 .for connectionivith the driven member. The', movable frictionvring 37is providedxvith slices corf respomding .teythose described anti..I W-ill designate. their by ...the Same :reference numeral with` fthe `addition of the exponent Arms also are provided in connection inner end vofthe crank will be moved', carrying4 With itlthe ring 27, as indicated in the diagrammatic views.

. Referring no. .Figc lpfihes .views a ywilli biasecathat` the', movement olf thecrank in th direction indicated by the ,arrow on the end .,ofthe crankwillexert a pulljon one af. the ,arms awhidiwold. seem tomise a .r tiQiLf-tlielrg A2.7. This .rotation will betreslsteihoivever, by the arm 35',1 oii the opposite side of the crank and by the loadresistingrotation of the movable friction .ring 3 7. The result is that one of the shoes 31 will become'locked on the stationary ring 28 and the bea-rings of' the arm 35 in the ring 27 will form a' fulcrum upon which the sleeve 27 will revolve, and the shoe 31 becoming locked on the movable ring 37 will rotate this .ring and the gear 39 and the driven member. The power in this case will be applied' between the fulcrum and the load, or through the crank to the ring 27 mounted thereon, and each arm 35 .will temporarily form a bearing through its shoe and the stationary. ring for an arm 35a land itsshoe to rotate the movable ring, the load being shifted from one arm to another as the ring revolves. The motion in effect will be a step by step one, but when the device is rapidly operated, the' movement will be pract1cally continuous and as the shoes and the bearings for the arms all operate inl oil, and without the use ofars, the movement will be practically noiseless and the casing being dustproof, there will. be no chance for dust and dirt to work into the bearings ofthe hoes and arms and interfere with the efiicieniy and durability of the gearing. A sleeve 42 is splined on theshaft 40 and has a clilteh connection at 43 for the gear 39. In Fig.` `1, this sleeve is shown in neutral position, but when moved toward the right will lock the gear 39 on the shaft for direct transmission of the power. A beveled gea-r 44 is loosely mounted on the sleeve 42 ranging them side by side in the housing to `forma doublebearing for the hub of a crank ,47,- said crank and its bearings being arranged substantially as described with reference to yFig. 1, the crank being made ,longer land the revolvinghub 4and bearing `rings-.being correspondingly enlarged to accommodate-this construction. VA stationary ring, similar-to the one described, which I' will designate by the same reference numeral, is secured to they housing and has a friction lringprovided with shoes similar to those illustrated in Figs. 2 and 3. A pair of rings 27v is provided in 4this construction encirclinggthe innere-end of the crank and havingP anti-friction bearings thereon, and thel arms 35 of the stationary friction ring 30 have bearings in onel of the rings 27. A ring 48 has bearing Vballs 49 in the housing and carries friction rings 50 and 51. These rings are preferably formed integrally with the ring .48 and are relatively stationary to revolvev with the ring 48. The ring 50 has friction shoes corresponding in their function to the shoes 31 of Figs. 2 and 3; that is, these shoes will become locked on the ring 50 in substantially the same manner as described with reference to the shoes 31 to oppose the shoes 31 on the friction ring 30 and impart a rotary movement to the ring 48.v The shoes of the ring 51 operate to multiply or increase the degree of rotation of the ring 48, the construction being a substantial duplication of that shown in Fig. 1.

The operation of the device is as follows: Power being applied to the driving member, the hub 9 will be revolved and when operated at a sufficient speed for centrifugal force to overcome the tension of the spring 23, the arms 19 ,and 24 will be thrown outward and their movement transmitted to the crank 25, one end of which is journaled in the hub 9 and revolves therewith, while the other end is concentric with the driving member. Obviously, the rocking of the crank 25, resulting from the outward movement of said arms, will throw the inner end of the crank out of its concentricposition and cause it to assume the' positions indicated in the diagrammatic views. The load, falling on one of the arms 35", will resist the tendency of the opposite arm 35, to rotate the ring 27 and the bearing of said arm will form a fulcrum between which and the load the power will be applied. The moveltt dill

mamon ment bodily of the ring, as indicated by dotted lines in lFig. 10, will result in the locking of the shoe 31 and the shoe l, gripping the movable ring, will force it around, and

through thegear mechanism described, will revolve the driven member. rl`he arms ,and shoes acting in pairs, will operate consecutively and a continuous revolution of the driven member will be obtained. As the speed kof the driving member increases, the arms will be thrown out a greater distance, the eccentricity of the inner end of the crank will be greater, and a corresponding increase in speed of the driven member will follow.
