STEAM-ENGINE GOVERNOR.

SPECIFICATION forming part of Letters Patent No.1 284,164, dated September. 4, 1883. Application filed December 27, 1882. Ne model.)

" To all whom it may concern.-

I Be itknown that I, FRANK H. BALL, a citizen of the United States, residing atErie, in

l the county of Erie and State of Pennsylvania,

have invented certain new andguseful. Im provements in Steam-Engine Governors; and I do herebydeclare the following tube a full, clear, and exact description of theinvention,

. such as will enableothers skilled in the art to which it appertains to makeand use the same.

This invention relates to steam-engine governors; and it consists in certain new and use:

ful improvements on the construction shown in Letters Patent of the United States No. 261,074, dated July 11, 1882, issuedto me. I l

The object of this invention is to simplify the construction of that class of governors,to

provide new parts or appliances, I and to gen erally improve the device, so as to obtain more perfect results. c c t I My device is illustrated in the accompany ing drawings, as.follows: I

Fig. 31's a perspective view ofthe partsB D E separated butin their relativepositions, the point of ob- 'servation beingfrom the right of Fig. 2. Fig.

Eithe valve-rod. F Fare thecentrifugal I balls connected by the arms F tothe spokes of the pulley G at f pivotally. F F are trade. construction here shown. I also found that it C. E is'an arm extending from the eccentric E, and connects pivotally at F with the cross-arm B. Other letters indicatingother parts will be referred to in proper connection hereinafter. I I

This governor works on precisely. the same principle as that in the patent above referred to; but in following. the construction there shown I have'found that many of the details can be simplified and many crudities corrected, and that many minor parts could be omitted and others re-formed, so as to be more compact. g The construction there shown requiredvariation as to size and adjustment of the various partsfor various sizes of wheels, thereby requiring a large outlay for patterns, &c., in

order to be able to supply the demands; of the This difficulty I have corrected in the was desirable toprovide anfielastic connection betweenthe arms of the balls and the crossarmor frame B, which I have supplied in the springs F The explanation of this point is as those points to the other, and the balls should move whenever the change of load occurs; but

follows: There are only two points in the revolution of the governor where it can act to move I I the valve-eccentric; but a change of load may occur when the governor is passing from one of 6., the springs F -any change of load occurring I while the parts are off the points at which the eccentric can move will be absorbed, I may say,.in these springs, and will by them exert its proper function as soon as the proper point is reached. A change of load then can effectits proper change in the relative positions of the drive-wheel and the frame at any time,

which change will either add to or takefrom the tension of the springsF and then as soon as the balls can move, and move the eccentric, as they must, they will be effected by this change of tension of the springs F. n In the present construction the balls F areconnected by the links D directly with the disk.D, the

said links being pivoted on the ballsandl connected also pivotally by the pins 01 with the M disk. Any centrifugal movement of the balls y will move the disk rotatively on the shaft. The outer face of this disk has thereon a circular flange, D, and a hub or sleeve, D". The latter is concentric with the disk, and the former is eccentric and forms afemale eccentric, into which fits a ring, D in which is a pinhole or eye, 0. On the valve-eccentric E is a pin, 6, which fits into the hole 6 on the ring D. The eccentric E receives its rotary motion by being connected by the arm E with the frame B at E, which connection is also pivotal, and therefore permits the eccentric to swing the length of its elongated shaft-opening. As be fore stated, the disk D is rolled on the shaft by a movement of the balls centrifugally, and

, any such movement will cause the female eccentric to roll upon the ring Diwhich is prevented from moving with it by the pin 6. The result is that the eccentric E is swung diametrically, and its eccentricity is changed thereby. Allthese parts are found in the patcut above referred to, but not identical in construction, the present form being much more compact and preferable, the novelty in this instance consisting wholly in the construction shown, the operation and the result of the operation being precisely the same in both cases.

One of the beneficial results of this construction is that the eccentric E can be smaller than in the other case. Another is that the device is more compact and looks neater and trimmer and more skillfully done.

The frame or cross-arm B is provided with horn-like lugs b I), which are hollow at the end and filled with a'rubber buffer, and serve as seats or rests for the balls WhGIIlJhG engine is at rest. The frame also has lugs b b, which abut against lugs on the wheel 0 at certain times-as, for instance, when the engine first starts up, before the balls have acquired any centrifugal force. These lugs interlock and carry the load until the momentum is suffieient to cause the centrifugal force of the balls to carry it. The pins d d, and those also on which the arms F of the balls are pivoted at f, are so formed as to form a ball-and-socket joint, so as to prevent any lateral binding in those joints.

The connection of the spring F with the arms F at F is made by a clasp or clamp, (F being a clasp or clamp,) so that it can be properly adjusted to or from the pivot f, as

' required to obtain thebest adjustment.

Any size of wheel 0 may be used. If one larger than that shown is used, the pivot f would be farther from the rim than in the present case.

I am aware of the patent to L. G. Skinner,

- dated October 17, 1882, No. 266,214, wherein the fixed frame and the loose pulley are connected together by a spring. I do not claim as my present invention anything therein shown. In my construction the fixed frame and theloose pulley are connected together.

through the centrifugal moving parts of the governor, while in Skinners device the congear, also mounted loosely on the shaft, centrifugal balls pivoted to said drive-wheel, and having their arms connected with said frame or crosshead, so as to resist their centrifugal movement by a flexible or elastic connection, and having also a connection with the said valve-moving gear, so as to move said gear as they move centrifugally, all said parts being combined and arranged to operate substantially as shown.

3. In a governing apparatus for. steam-engines, substantially as herein shown, the centrifugal'balls hung on the drive-wheel, which is loose on the shaft and connected with a frame which is fixed on the shaft by an elastic connection, which is arranged substantially as shown, whereby the motion of the shaft is communicated to the drive-wheel through the said frame, the elastic connection, and the arms of the centrifugal balls, as shown.

4. In the governing apparatus of a steam-engine, the combination, substantially as shown, of the fixed frame B, the loose wheel 0, the

balls F, pivoted by their arms F to the loose wheel, and connected by said arms with the said frame B by the springs E the disk D, connected with said balls by the links D and with the loose wheel 0 by the springs S, and

bearing the eccentric D, and finally the valve moving eccentric E, connected with the frame B by the pivoted arm E and with the eccentric D by the pin e and ring D v 5. In a steamTengine-governing apparatus, substantially as shown, the disk D, with female eccentric D on its face, and the contained ring D in combination with the slotted eccentric E, the arm E, and the pin 6, and the pin-hole e in the ring D, all substantially as shown.

6. In a steam-engine-governing device, substantially as shown, the arm or frame B, provided with lugs or catches, b, for engaging or clutching the drive-wheel O, substantially as and for the purposes set forth.

In testimony whereof I affix my signature in,

presence of two witnesses.
