IMPROVED GOVERNOR FOR STEiAli/I .AND OTHER' ENG-INERY.

The Scheule referred to inl these.Letters Patent and -m'aking part of the same.

To all whom it may concern Be it known that we, WILLIAM J oHANNES.KESsEL MEYER, and CHARLES AUGUSTUS KESSELMEYER, of Manchester, in the county of Lancaster, in England, and EMIL HERMANN NACKE, of Als-Schoenfeld, in the Kingdom of Saxony, have invented anew and irnproved Governor for Steam and other Engines; and we do hereby declare that the following is a full, clear, and exact description `thereof,;which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawifngs, forming -pait ot' this specification, in which the drawing represents a sectional elevation of our improved governor for steam and other engines.

This invention has for its object to render centrifugalgovernors more effectual in regulating. the speed of theengine, so that the speed will he immediately corrected as soon as it shall vary. l 1

The invention consists -in the combination, with the movable valve-rod, of a vessel containing liquid matter, and .in the arrangement. of the same with a s tationary vessel, in such manner that when, by the contraction ofthe governor-balls, the movable vessel islowered,the liquid will Ilowinto it fromf'the reservoir, `and will load it. The movable vessel will, when thus weighted, tend to open the valve without loss of time, as it descends quicker.' When the balls are spread to raise the vessel, the liquid ows out from the saine into thereservoir, andlightens the valve, to allow its more rapid closing. The speed ofthe engine is thereby regulated with great rapidity, as tl'iedeastvariation in the position of the balls will causen correspending variation in the weight on the valve, and a consequent rapid action on said valve.

In the drawing- A A are the governor-balls', mounted, as usual, on the levers B B, which are pivoted to the hollow driving-spindle G, and which are connected by the rods "a a with the sleeve D.

This sleeve slides ou the spindle, and is, bya crossbar, b, or byvother connecting-pins, passing through slots of the spindle, arranged to support, or fastened to the rod E, that is within the tubular spindle, as shown. Y

The sleeve D is connected with the lever H, which communicates motion to the ordinary throttle, or other valve.

Upon the upperend of the rod E is affixed a vesgel, F, which 4is tp contain mercury, water, or other G is another vessel, of Asimilar size to F. It is placed stationary, -so as to be about on the same level with F, when the engine is at its proper rate of e speed.

The two vessels F G are connected with each other by flexible or other pipes, or siphons, or other equivalent devices, so that whatever be their relative position, the liquid in them will be as in one vessel, and constantly tending to be on the same level in both.-

In the drawing are represented two pipes I 1', the former connecting the lower,v the latter, the upper parts of the two vessels, the one being for the passage of the liquid, the other for the air.-

Asi the balls of the governor ilyout or collapse,

'the sliding collar will carry the rod E up or down with it, and will thereby raise or lower the vessel F. NVhen the same is raised, the liquid will flow out of it into the reservoir G, and F will' therefore become light, and will facilitate the raising ot' the rod E, and lthe closing of the valve. When, by insulcieut snpply of steam, or other motive-matter, the balls should collapse, they will cause the sleeve to'draw the rod E, and with it the vessel F down, whereby liquid will be caused to iow from G into F. t

The weight of F is thereby increased, and the downf ward motion aided in Such manner that the valve will be quickly opened, and the proper speed obtained.

When the engine has lthe requisite `degree of speed,

-the vessels F G will be in the position indicated in the drawing, so that they are both about half full. When lowered, the vessel F becomes nearly filled;

when raised, as by dotted lines, it will he almost emptied.

Another advantage obtained by our invention is, that the governor will keep the valve opened -orcloscd for a longer tinie'than it would it notlprovided with our attachment.

Nh'en the valve is opened, the weighted vessel will keep it open during a certain nomnal number of revolutions, while otherwise the instant spreading of the.

balls would have left the valve open, but very insufficiently.

In the same degree will the'lighter vessel tend to retain the balls spread dui-'ing a certain normal number of revolutions, when the vvalve is to be closed,

while the ordinary governor'would instantly open said valve as soon as the lballs would commence to collapse, which /they will do instantly as the 'supply of st eaxn is reduced.

The vessel G may be .connected with the nia'- ohinery, so as to move in opposite direction, or in nnequal proportion to the motion of F.. It is, however, preferable to have it fixed.

The mechanical connection of the governor-valve and vessel F with each other maybe varied, and will, The above specification of our invention signed by of necessity, be varied on governors of diierent conus, at Mulhouse, this 20th day -of April, 1869.
