SPEOIFICA'FION forming part Of Letters Patent N0. 604,798, dated May 31, 1898. Application filed January15, 1898. Serial No- 666,771- (No model.)

To all whom it may concern.-

Be it known that we, JOHN WALTER SMITH and ALBERT H. ANTHONY, citizens of the United States, residing at WVorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful improvement in Governor Mechanism, of which the following, together with the accompany- 111g drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

Our invention relates to the manner and means for connecting the levers of the revolving governor-balls with the endwise-reciprocating valve-operating spindle or rod for transmitting and converting the motion from the former to the latter in the operation of the governor, the objects of this invention being to provide an efficient and desirable connection mechanism that will work easily and smoothly without looseness in the runn ngoints; also, to render the mechanism simple and convenient for accurate manufacture, steady and durable in its working parts, not subject to rapid wear, and not liable to derangement when'i'n use. We attain these objects by the mechanism illustrated.

in the drawings, Figure 1 is a side view of a governor embracing our invention. Fig. 2 1s a transverse section at line am through the connecting-joints. Fig. 3 is a vertical section through the valve-rod head and joints. Fig. 4 1s a top plan of the joints and center block. Fig. 5 shows a separate view of one of the joint-rollers, and Fig; 6 shows a modification in the position of the joint-rollers and finger-pins.

In referring to parts, A indicates the rotary head or sleeve, provided with pulley A and arms a and mounted to rotate on the tubular bearing 13, that is fixed to the valveframe. (Not shown.)

(J (3 indicate the governor-balls, d the balllever pivots, E the springs, A the spring-supporting bar, E the tension-regulatingscrew and plate, and F the valve-actuating rod, all of whlch parts may be of suitable or wellknown construction.

Our improved means for connecting the swinging ball-levers O with the endwise-movable valve-rod F comprises a swiveling piece or center block mounted on the valve-rod head and running between oppositely-faced conical bearing-surfaces and having a hinging attachment with the ball-levers composed of trahsversely-disposed j oint-rollers or rocking cylinders, in conjunction with finger-pins that engage holes in said rollers perpendicular to their axis and have endwise or sliding movement therein, while the rollers have rocking motion in their seats, thus aifording an easily operating, steady, and durable mechanism for transmitting and converting the motion from the balls to the rod, as the latter is thrown up and down by the action of the balls when they are efiected by various speeds of rotation. In this connection, G indicates the valve-rod head, which is formed with a cylindrical hub to which the valve-rod F is attached by pin 3, also with a flange 4, have ing a coned top surface and a center stud projecting above said flange. (See Fig. 3.)

I indicates the center block, having a central opening with upper and under conical bearing-seats to match the cone-flange 4 and to receive the fiat cone-shaped cap or washer .l, that fits into the center block and is secured to the center stud of the valve-rod head by a screw J, that is threaded into an axial opening therein. The center block I is thereby secured to revolve freely, but without backlash or tilting motion, on the head of the valve-rod.

M M indicate the joint-rollers, disposed at either side of the center transverse to theaxis of the governor rotation and parallel with each other, as'shown. Said joint-rollers are fitted to have easy rocking motion in cylindrical openings in their support and are best arranged to extend from side to side of the center block, as illustrated. At the center the roller M has a hole m bored therethrough at a right angle to the axis of the roller, (see Fig. 5,) and the joint-roll bearing is recessed through its outer face, as at n, to permit entrance thereto. I are each provided with a hard steel straight finger-pin P, that projects rigidly therefrom and enters the hole m in the rollerM, fitting therein closely, but so as to slide easily inward and outward endwise.

The ends of the ball-levers When the ball-levers rise and fall, the finger-pins and rollers accommodate themselves to the varying angularity between the levers and the center axis, maintaining a free working connect-ion withoutunnecessary loosenes's, the roller rocking, in its seat to conform to the movement of the finger-pin and said finger-pin having a slight endwise movement in the hole 112 to accommodate the varying distance between pivot centers as the levers swing up or down. This construction produces a very durable, efiicient, and desirable governor connection.

In Fig. 6 we have shown a modification in construction which may in some instances be employed, if desired, and in which the position of the finger-pins and rollers is reversed, the finger-pins P being fixed to the center block I and the joint-rollers M seated in the ends of the ball-levers C The operation in this instance is substantially the same as that above described.

It will be understood that we do not make claim to the arrangement of the governorball,'the springs, and spring-ten'sion-adjusting devices mounted on the rotating sleeve for operating a central valve-rod, as such parts of the mechanism have heretofore been employed.

What we claimas of our invention, and desire to secure by Letters Patent, is-

1. In a governor, the combination with the ball-lever and valve-actuating rod; of a center block running on the valve-rod head, and a connection .from said center block to said ball-lever consisting of the transversely-disposed j oint-roller and the finger-pin engaging with said roller for operation substantially as set forth.

2. The combination, with the swinging governor-lever, and the swiveling center block carrying the endwise-movable rod; of the transversely-disposed roller mounted to rock within a cylindrical recess formed in one of the parts, and a straight projecting fingerpin rigidly fixed on the other part and extending into a hole formedin said roller perpendicular to the axis thereof, and movable therein, substantially as set forth.

3. The combination, as described, of the valve-rod, the valve-rod head having the conical-faced flange and centering-stud thereon, the conical-faced washer fitting over said stud, its fasteningscrew, mounted to turn on said head and having cone-shaped recesses matching said flange and washers, the governor-ball levers and a hinging joint connection joining said center block and governor-ball levers, substantially as set forth. I

4. In combination, the rotatable sleeve having the bifurcated arms, the governor-ball levers pivoted to said arms, the central valverod having the conically-flanged head, the center block mounted on said head to turn freely between the conical bearing-surfaces, the joint-rollers arranged in transversely-disposed openings extending across the opposite ends of said center block, said rollers having a hole thereinperpendicular to their axis, and the finger-pins respectively fixed in the governor-ball levers and fitting into the holes in the joint-rollers, for the purposes set forth. Witness our hands this 12th day of January, 1898.
