AUTOMATIC eeviiiiiioii Application filed November Y5, SeriaIVN-QQQYJEQ.

Thisinvention relates to an antomatic governorand as illustrated and described herein, it is particularly adapted for use, for controllingthe time of ignition in an internal that the spark ade vance should be substantially coincident with the increase in the Speed o the engine, and contrarirvise shonld ybedeerease:d with a de crease in speed of the engine. It is pracf tically impossible to get proper mannal control ,of the ignition spark, control. I

lllyfinvention is therefore directed to iinprovements in automatic governors for nit-ion spark control. Y Y Y ln various `devices of the prior art, with Weich I am familiar, it is the nsnalpractiee to pivot theweights or Weir ated arms at one end, such .for example as illnstrated in the Vllioore PatentrlSSJFi, issued August 23rd, 1921? but l have found that such an arrangement reduces the eli'ective force of the Weights, that is to say, those portions ot the Weights near the pivot points produce but little effect, as will be apparent from a study of such air arrangement. Y

Another objection which I have found to a structure similar to that shown inthe said I" isfivell understood ltloore atent is that the ends of lthe Weifrhts i p 7 i i C) 5 being some distance from the pivot points areapt to flop` back and forth at low speed, striking the vdriven member, and thereby producing a noise. i

Aistill turth r'objection to a' governor of thcftype disclosed in said Moore patent, is that it is not strictly interchangeable for different directionsot' rotation ofthe operating snat't, th at is to say, if it is desired to rotate a governor of the Moore type opposite in direction from that first intended, the weights must be assembledV in reverse Aposition in `order to get good ooperation..v

One of .the'objectsl of my invention is to provide a governor for the purpose herein described, inwhich the Weights -are substantially equally balanced ,on a central median line, whereby the centrifugal Aforce acts imi-A Vtormly on all parts of the Weight.

Another object of my invention is toV provide a governor which Will operate vequally )yell in either direction or" rotation, Witlioiit l shifting the position of any of the parts.

Another obgect of my invent-ion is to pro-f governor in which the friction ,1S fiberv oecd a mininlinn.l

Another. object oi my invention is tov pro# vide an arrangement in which link connections between the Weights 'and the driven member are providedlivith bearings'on both ,Sides 0i, the limiet@ insure loiigflif Lof iii@ C the Se@Ci'iiiciti. iii, taken iii ,Connection with the o annexed drawing 'g wherein 'Figure 1 iS'fi'pia'ii vivei the ,governor I' with the cover removed, and showing-the parts in normal idleor retard yposition."'

stem 5 Iis preferably tapered Vto receive the 5 tapered end iof *of the ignition` unit7 such as a magneto. 'A nnt`7`sho'wn' inFig-. nre lOfbeing provided to `Within the `bore 8, oft the driven i Glan beine* thread'- ico shaft of the ignition unit. A keyivay 10, is provided vin the stem 5, and as the end 11, of the nut 7, comes against the angular shoulder 12, Vdriven member 6, is drawn into rm engagement With the shaft of the ignition unit.

The member 1, is provided on its inner surface With flanges 13, which extend clear across the inner face thereof thereby forming a groove or guideway 14. Y

Positioned across the flanges 13, and substantially symmetrically disposed with rel spect thereto are a pair of Weights 15 and 16; these Weights are preferably made upl of three punchings fastened together as by means of rivets 17. The middle lamination is cut away at its central portion, as indicated by the dotted line 18, to provide clearance for one end of link 19, Which has a pivot pin 20, preferably immovably fastened thereto, so that the ends of the pinsy have a bearing in the top and bottom pieces comprising the Weights 15 and 16, all as clearly shown in Figure 3. The pivot pin 20, eX- tends beyond the Weight 15 into the groove 14, and carries a roller 21, thereon, Which is likely to move vup and down in the groove or guideway 14, in engagement With the sides of the flanges 13, as the Weights 15 and 16 respond to centrifugal force. The middle lamination of Weights 15 and 16 has extensions inthe form of hooks 22, and these adjacent projections or hooks are engaged by springs 23, and 24, whereby the Weights are heldin retard position as shown in Figure 1. The inner ends of the links 19, are pro-Y vided'with pivot pins 25, that are preferably immovably attached to the links, `but the ends of the pivot pins 25, are movable in the holes 26 ofthe lugs or lears 27, which extend from the driven member 6. rIn order to eliminate or reduce to a minimum any noise which the Weights might produce on returning suddenly to retard position, I provide thev driven member With' bumpers 28, of vsome suitable material, such as fibre or rawhide, on Which the Weights rest in retard position.

Since a complete housing for the driven member 6, is provided by the parts 1 and 2, a drivin connection must be made to the casing, Vt is is done through the mediuln of a plurality of studs 29, three being shown in Figure 5. The studs 29 are fastened to the cover in any satisfactory manner. Likewise the cov-er is held to the rigid member 1, by a pair of studs 30, Which pass through the holes 31,V as Will be seen from Figures 5, and 6, and 7. It is to be understood that a suitable coupling member is adapted to engage the studs 29, to drive the governor and the ignition shaft.

The governor so far'described Will produce substantially a straight line curve, but for certain requirements this straight line curve requires to be modified and this modification can be brought about, by the use of an auxiliary spring associatedwith the Weights. For this purpose Iv preferto use a flat spring 32, Which may be att-ached to the Weights in any satisfactory manner, that shown in the drawing comprises a flat surface in the outer part of the weights on which the `flat spring 32, rests; thesprings are held in position by peening over the metal as shown in Figure 3. It Will be understood that Vthe springs 32 are of suitable thickness and quality to give the desired modification to the spark advance curve as the ends of the springs 32 engage the inner Wall of the rim or cover 2, when the vWeights move away from the center.

In place of the hooks shown in Figures 1, and 2,'the central lamination of the Weights may be constructedwith eyelets 33, as shown in Figure 4. Y Y

The operation of my device will be apparent Without any 'extended description thereof, but it'may be pointed out, that the Weights are so positioned over thenarrov flanges 13, as to produce little friction, and the Weights'are so disposed as to be acted on uniformly by centrifugal forceV and consequentiy they move in a lateral direction from the driven member, beingguided by the rollers 21, operating in the gudeway 14. As the Weights 15 and 16 move outwardly toward the rim of the cover 22, under the action of centrifugal force the driven memberr 6, is shifted inrposition or advanced so as toV advance the time of the spark produced in the engine cylinders. 'The auxiliary spring 32 as has been pointed out, is arranged of suitable thickness and length and material as to modify the speed of rotation ofthe given member as desired, to produce the necessary spark curve.

It will also be apparent that the governor canbe operatedVV in eitherdirection of rotation Without any change in position of Vthe weights orv their associated members. Furthermore the pivot pins associated with the links being fastened rigidly to the links and having bearings on Vboth sides of the links, Agives a structure insuring longservice for these parts. A

It Will be apparent that various changes may be made in the details comprising the governor herein described and I therefore do not Wish to be unduly limited in the interpretation of the appended claims.
