RARTHURJ. HARTLEY, OF PEOBIA, ILLINOIS, ASSGNORTO HART GRAIN WIGHER C0., i PEORIA, ILLINOIS, A CORPORATION OF LLINOIS.

GOVERNOR.

Application filed April 7,

To all whom it may concern:l

Be it known that I, ARTHUR J. Hmmm,-

acitizen ofthe United lStates of America,

residing at Peoria, in the. county of. Peoria nection *with the annexed drawings in `which vv Figure -1 is a side' elevation, portions' and State of Illinois,'have invented certain new and useful Improvements in Governors,

of which the following is aspeciication. The objectof my invention is in the pro:

vision of a. simple, eicielnt, and easily con-4 structed governor to beconnected with a driven'shaft which vhas mounted thereon a driving member.

pear in the ollowing-'specificationin conbeing shown in section of the governor'. .A

Figure 2is a sectional view on ythe line 2-2yof Fig. 1. i

Fi re .3 is a sectional view taken on the line 3--3l of Fig.- 1.

lFi 4 is an elevation showing in detail t e mounting of the friction band and its relation to member.-

4 Figure 5 is al view in section illustrating the manner inv'which the weight members are connected to the friction band.

Referring to theA drawings, 10 'shows a driving shaft in connection with any power means, not shown. A governor casing 11 havin its outer end fianged as at 12 has its hu 13 positively connected to the driving shaft. v Contained within the casing, or rather the outer shell of the governor, are

' various elements and a hub member 14 is also connected to the driving 'shaft as an means for holding the operating auxilia parts o the overnor within the outer cas ing. A mem er 15 bracketed about the hub 14 has the guideways 16. therein, said guideways containing slidably therein the lower ends 17 of the 4rods l8-.-said.rods projecting through vapertures 19 in' the flanged portion-H of the governor casing. The. rods 18 have abutments at their upper ends shaped as at 20. Coil springs 21 encircle the' lower por-f tions of the rods and. abutting the upper ends of said coil sprin s are the inner ends 22 of the -weight` mem ers 23, saidv weight members havin pivotsas at 24 inthe gov ernor casing. t may be noticed that. the inner ends of the weightA members are apertured 4as at 25 to encircle the rods 18 y end of the portion '26.

.member 26 and `thus provides a positive attachment therewith. The lever 27 has the spaced arms 30 which vhave a pivot member 31 extending between their outer ends and said Vpivot member having attachment with a friction band 32, said band .having a friction material 34 on its inner side. This friction band surrounds the hub 35 of a mountedv on the dr1ving shaft 10.

The other end of the friction band; is

'connected as at 37 to a bolt 38 having adjustable mounting by means of the nut 39 with .the casing 11. The coil spring 41 holds the bolt member in tensioned relation' with the frame portion.

The operation of the device is as follows: The movement of the driving shaft lO rotates the governor'casing and the portions therein inasmuch as the governor is .fixedly mounted on said driving member. 'Inasmuchasthe initial rotation of the driving member and governor-is slow ,the centrifugal force on the pivoted weight members will be '--slight andfthey will be moved outwardly very litt'le'if at all. However, an increased rotation of the governor with the shaft will, through the centrifugalforce, exerted on the vweight members throw the weighted ends of said membersoutwardly with the result that they Will be moved on their respective pivots. This pivotal movement is also being resisted by the coil springs 21 inasmuch as itis not desirable that'the friction band of the 'governorjact until the driving-shaft has attained avery high speed.Vv One of the pivots of the weight. members, that is, `the one which casingand as the-square .outer end, will have .said'outer end moved tocorres ond` '-'with the pivotal movement ofthe weig ted.

upon the hub 35 of the driven member 36 with the result that said driven' member will be rotated with the shaft 10.

Likewise a slackening of the speed of the driving shaft will p'ioduce a respective action in the governor, that is, the weighted members will tend to assume-their normal position and the squared endof the pivot 26 will be moved in an opposite direction,- with the result that the friction bandwi-llbe slackened about the hub of the driven' member and said driven member 'will cease .to rotate with the driving shaft, and the devices not shown that are driven by said driv- 4 ing member will likewise cease to be -operated. What I claim isz,

1. In a device of the class described, a

v driving shaft, a Acasing positively connected thereto, weight members pivoted within the casing, r'od members slidably related to the inner ends of the weight members and engaging the casing, coil springs surrounding said rods and resisting outward movement of the weights, a' driven member loosely. mounted on the driving shaft and having al ythe friction band. Y v 3 'In testimony whereof- I have aiiixed my' 2. In a device of the classvdescribed, a

driving shaft, a casing positively connected to said shaft, weight membersprvoted with- 1nl the casing, tensioning rods passing through the shorter ends of the weight members, a centrally located hub portion adapted to receive. the inner endsof said tensioning rods, coil -springs surrounding said rods and providing means for tensioning the Weight members, a driven member loosely lmounted on the driving shaft and having a friction hub in connection'therewith, a friction band l surrounding said hub and means for relating one of the 'weights with the friction band whereby movement of the weight will produce a tightening or rele'asin'g action of signature. v
