GOVERNOR HPECIPICATION forming part of Letters P'atent Nof356f644, date-d January 25. 1887.

Application filed April 14,1886. Serial No. 198,822. (No model.)

To LU whom t may concern:

Be it known that l, JOHN E. HUGON, of the city of Bichnionthcounty ol' Wayne, and State of Indiana, have invent-ed certain new and useful Improvements in Governors for Steam- Enginee, of which the following is a specification.

My said invention relatesto that class of steanrgovernors in which the governor-balls are connected direetly'to the governor-rod by straps or springs sec-ered to said rod and said,

halls, as will he hereinafter more particularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof, anden-whichsimilar letters of reference indicate similar parte, Figure lis a side elevation of a governor and its connections embodying my said linvention," Fig. 2, a central vertical section of the saine; Fig. 3, a view similar to a portion of Fig. 2, wit-ii the governor-balls extended; and Fig. Il, a top or plan view of Fig. l. Aln said drawings the portions marked A represent the governor-frame, in which are hearings for the various operating parts; B, the governor-rod, thronghwhich the governor operates on the valve, and which also revolves with the governor; C, the revolving hollow shaft surrounding said rod and carrying the governor-balls; D, said governor-balls, 'and E and the governor-balls.

il i

frame A is secured'to the shell of the` valve, as shown', in the ordinary manner, and' contains bearings for the` drivinggshaftA of the governor and the hollow shaft C. It also carries a bellcrank lever, A, to which a rod, of, is connected, `and liy the spring a'on said. rod al the valve-connection B is heldin contact with the rod B. .The redt B passes up through the hollow` shaft Gyand its upper end or head, lavis connected by means of the strapsor springs E to the governor-balls. Its lower end rests upon the vconnectionf', which connects directly'with and operates the valve.V

Being connected te the governor-balls,thisrod,

of conrserevols'es therewith.

The hollow shaft C is mounted in bearing in the frameA, as shown.

Itcarries f a 'nevel gear-wheel, c, upon its lowerend,

which engages with a similar bevel gearwheel,

.the operation' of y'rod a", and the spring a, thereon vcased, to' rise, as is also the connection B', and the valve' a vertical v a', on the shaft A', and a yoke, C', uponitsv upper end, in which the governor-balls are pivoted. This shaft is provided with collars at both ends of its bearing in the frame A,

(which consist, preferably, as show-n, of the' yoke and the bevel gear-wheel, or are formed integrally therewith,) and therefore does not.

move vertically, but is only revoluble. v The governor-balls l) are substantially the usual spherical,governor-balls, the 'stems of which are bellcrank lcvers,.as shown, (see, particularly,

pivots d to the yoke C.

thecenters of the pivots, as shown.

The straps or 4connections E are ,thin steel springs, and are connected at one'end to the Figs. 2 a'n d'3, and are pivoted ,atthe points of these bell'crank levers hy The inner ends ofthe arms of these bellfcra'nk levers are pref-, era'bly finished as arcs of circles struck fromA head b of the rod B, and at the other ends di'v 1 rectly tov the balls D by screws e e', as shown," or otherwise. These springs rest against the arc-shaped ends of thebell-crank levers, (thereby maintaining the same position laterally without reference to the position Iof the balls,)

and thus pull in the same direction on the rod B at alltimes. e

'gAs will be observed, in my governor the yokevcarrying the governor-balls is not subject to any vertical movement, but revolves'al` ways in the same plane, the operation upon the valve being entirely through therod B.

and connections BQ The operation of Vmy said'invention is as follows: WVhen the speed of the engine tends to swing the governor-balls D out, ythe straps or springs E, because of thei them to do so, length remaining 'the samefthe springs, and with .them the rod B, are drawn down to close.

the valve. -When the-speed of the engine decreases, the AgeveThor-.balls D will fall, which r flexibility, permit` and at thesah time, their.

operation isaided by the retractile poweroi 5 and the rod B is thereby andby the springs,

the bell-crank levenA, its

eniployedas a means of connection between a rod or shaft having no vertical movement and devices to which vgovernor-balls were eon nectefi, whereby as said' governor-bells' Wore forced outwardly by centrifngei force the head carrying said devices and governor-balls Wouid be moved, longitudinally on seid shaft; but I am not aware that pivoted governor-balls seoured 'to a; yoke not longitudinally movable,

' ing-shaft, and e.l hollow vertical shaft, seid'liollow vertical shaft being secured fromlongitudinal movement in its bearings and carrying e.- yoke to which the governor-ballesy are pivoted, said governor-balls having bell-Crank-Shaped arms and pivoted to said yoke, a vertically-- moving valve-rodlpassing through seifl hoilow shaft, and springs secured to a, headlon said rod and to-saitl governor-balls, and bem- -ing against the inner ends of the bell-crank- Substantiall5v as set shaped arms of said boils, forth.
