IMPROVEMENT IN GOVERNORS FVOR STEAM-ENGINES.

Speccation'forming part of Letters Patent No. 171,939, dated January 11, 1876; application tiled Ma. 7 5, 1875.

To all whom it may concern:

Be it known that I, AARON K. KLINE, of Somerville, county of Somerset and State of New Jersey, have invented certain new and useful Improvements in Steam-Engine Governor, of which the following is a specification:

My invention relates to that class of governors in which the valve is operated by meehanism consisting of a beveled sleeve, in combination, by f'riction, with a disk or circular plate, the beveled sleeve working vertically outside a vertical shaft, within which is a stem connected with weighted arms, the sleeve con vnected with the stem by a pin passing through a slot in vertical shaft, and as the sleeve is brought (by speed ofthe engine operating upon the centrifugal balls) into contact with thel disk the valve is opened or closed; and the nature of my invention consists,first, in a new and improved construction of the disk, which is made of thin metal, and provided with a beveled rim, sloping forward and having a gain7 or cut-away77 in the rim, at what 'would be its uppermost point when at rest and valve closed. It is also provided with slots having bolts, whereby its position is regulated with regard to the yoke behind, and with which it is in combination, the yoke supporting it, and also connecting it with valve-stem.

It further consists in a combination consisting of horizontal driving-shaft, beveled cogwheels, vertical shaft, weighted arms, screwhead, stem-pin, beveled sleeve, disk with bevelgain or cut-away, slots, bolts, yoke, and valvestem.

llhe beveled cog-wheels' connect the horizontal driving-shaft with the vertical shaft. The weighted arms are supported by and pivoted to the vertical shaft, and their inside ends arranged to run in a groove of the screw-head, which is threaded upon the upper end of the stem, as to be adjustable, and the said stem is placed vertically within the vertical shaft, and the pin forms the connection between said stem and the beveled sleeve. The beveled sleeve is arranged. around outside the vertical shaft, and the pin passes through a slot in the vertical shaft, so that the sleeve may slide up and down according to the 'rise g rise or fall.

the

bevels at its upper and lower ends corre-v sponding with the beveled rim of the disk,

against which it operates by friction, eachv bevel being brought into contact accordingly as the centrifugal force causes the sleeve to The disk is circular. The rim nearly surrounds it, a portion being left out or cut-away at the place which would be uppermost when the valve is closed. This forms the gain or cut-away before mentioned. disk is also provided with slots, through which are passed bolts', connecting it with the head of a shaft projecting behind, and the said shaft-head is so placed (with regard to the shaft proper and the disk) that an eccentric is formed, which, working within the yoke to which the valve-stem is attached, and revolving with the disk, causes the opening and shutting of the val ve.l The yoke is arranged to stand vertically, with the valve-stem projecting from its bottom, but, by turning it around horizontally when the valve' is at one side, it will operate/equally well. The yoke straddles kthe eccentric, and the curved surface of the same comes in contact'with a head,

and foot bar of the yoke, so that the yoke must rise and fall as the eccentric is revolved. The connection between the disk and eccentric is made adjustable by means of slots and bolts, so that the action of the valve may be regulated to a nicety.

The several working parts of the governor are supported by a proper standard with base, 85e., the shafts passing through proper collars therein.

The eccentric-shaft is provided with proper devices, by which the pressure of the diskbevel against the bevels of the sleeve is adjusted and the proper amount of friction regulated to suit the requirements.

Figure l is a perspective view of the governor in front. Fig. 2 is a perspective view of the same governor from rear. Fig. 3. is a vertical section of the same. Fig. et is the disk and eccentric, the disk viewed from front and the eccentric shown by dotted lines. Fig. 5 is the eccentric shown from front and the position of disk by dotted lines.

A represents the base of the governor. b is The l the vertical standard, curving over at the top tor'eceive the shaft c, which passes downward through said standard. The shaft rests in the base-plate a, and extends upward to d, where are formed two brackets, extending outward and upward to c, where they turn inward and upward, meeting in a cap, f, at top, forming the apex ofthe governor. At e the Weighted arms h pass th rough said brackets and are pivoted thereto. The said arms h are provided with baILWeights h', loosely slid thereon. A

nut running on a thread of thearms forms a medium of shortening the reach, if desired, as

shown at i. At j the inner ends of the arms `are provided with rounded heads, fitting into a groove of the outer surface of the screw-head k of the stem k1. The screw-head lo runs upon a threaded portion of the stem, and, by turning it upward or downward, the play ofthe balls his lengthened or shortened as desired. The stem k1 passes downward through the shaftc, inside the same, and at Wis a pin connectingit to the sleeve l. The pin plays upward or downward (in agreement with the riseor fall of the balls h) and through the vertical slot m in shaft c. The sleeve L is provided with bevels L1 and l2, arranged to correspond with'andcome in contact with the beveled edge nl ofthe disk a, so that the disk may be turned bythe friction. The disk n is circular, and hasta beveled edge, al, reaching forward, as shown. A portion azis cut away. leaving no bevel, so that when that portion is opposite the bevels l and Z2 of sleeve VZ the disk is not in contact therewith. The disk is fastened to the eccentric o by screws or pins ol and o2 passing through slots a3 in central portion of disk u, so as to be adjustable. The eccentric-shaft is shown at p. The collar is shown at g, and valve-stem at r. At tandit are the beveled cog-wheels,forming the geart ing connecting the vertical shaft c of the governor with the horizontal or driving shaft u,

having pulleys u1 u2, said shaft passing through y standard @inside-projecting collar v holding l it in proper and steady position. Atlw is i shown the @set-screw, which is run into the collar q, its inner end rounded or pointed, and"` abutting against the end of the shaft p." A ,t nut, w, is run upon and `Wrenched up after the i l desired pressure has been obtained, solasito ,i

hold it in position. The object of these devices is to regulate the pressure ofthe disk m `against the bevels of sleeve l. By turning` the eccentric o around, bringing the valvestem to the side, it` may be` operated to `open and close a valve in that direction. `A yoke,

c, connects valve-stein r with eccentric o.

. What I claim as new,anddesire to secure l by LettersBatent of the UnitedStates, fis,-

1. Disk n with bevel n1, gain or cut-away x n2, slots a3,bolts' 01 ando", eccentric 0,'eccentric-shaft p, and yoke z, all combined tooper-` ate substantially in manner `and for thep`u1- pose described and set forth. L

2. Driving-shaft w, cogs tand t', vertical" shaft c, weighted arms h,\screwheadk,l`stenr k1, pin k2, sleeve l, providedvvith bevels l and l2, disk n, with bevel nl, gain or cutaway `a?, l 3 slots a3, bolts 01 and o?, eccentric o, eccentrici shaft p, yoke z,'and valve-stem r, all combined to operate substantially inmannerand for the purpose described and setlforth.
