BENNET B. SMITH, OF NASHVILLE, TENNESSEE, ASSIGNOR OF ONE-HALF HIS RIGHT TO WILLIAM H. MCDONALD, OF GREEN HILL, ALABAMA.
IMPROVEMENT IN GOVERNORS FOR STEAM-ENGINES.
Specificationforming part of Letters Patent No. 137,573, dated April 8, 1873 application filed January 29, 1872.
To all whom it may concern:
Be it known that I, BENNET B. SMITH, of Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Engine- Governors, of which the following is a specification:
Nature and Object.
The object of my invention is to produce a governor capable of wielding more power for working the throttle-valve than that derived from the governor-balls when thrown out or raised by centrifugal force by the rapid rotation of the same, or fall by their own specific gravity when the velocity of said rotation is diminished; and also to move said throttlevalve a great distance with a slight variation in. the position of said balls. My invention consists of a shaft provided with a right and left hand screw, revolved by a hollow driving-shaft, into which it enters and reciprocates. To said driving-shaft is connected (by bevel-wheels) the shaft, which is connected with the governor-balls. The firstmentioned shaft, which is in constant rotation, is caused to reciprocate by two threaded plates alternately thrownin contact with either of the screws upon said shaft by the action of the governor-balls, as hereafter described; and to said reciprocating shaft the throttlevalve or other cut-off contrivances are attached by suitable connections.
General Description with reference to the accompanying drawing,
dicated by the letters D and E, the former being a right and the latter a left hand screw. K is a bevel-gear wheel attached to shaft A. L is a bevel-gear wheel attached to shaft M.
the accompanying drawing. J is a beam os-.
cillating upon a fixed center and connects F with G, (another reciprocating rod,) and compels them to move in opposite directions. Rigidly attached to the bottom of F is a plate, H, having grooves at the bottom to correspond with the threads of screw D. I is a plate similarly attached to rod G, having grooves at the bottom to correspond with the threads of screw E. T is a rod situated between the screws D and E, rounded at the bottom to correspond with a groove in shaft 0; at the tops T is connected with (and oscillates upon) the center-pin of J. Said rod T is provided with two toes, one of which is brought in contact with either side of beam J. This is for the purpose of lifting either of plates D and E out of gear with its respective screw, when shaft 0 travels further than to perform its required duty.
Operation.
Considering the above-described apparatus to be in connection with an engine, the steamsupply of which is regulated by the valve U in connection with rod 0, and the drivingshaft A properly connected with the engineshaft to revolve in proportion to the same, to
support the balls N N by centrifugal force in their position shown in the drawing when the engine is running at the desired speed, it.
which will increase, and the said balls N will lift the plate I from E, preventing further action of O in the direction mentioned; and should the speed of the engine still increase,
the action of the balls will throw plate H in contactwith screw D, and the shaft 0 will be moved in the opposite direction to the arrow, causing the valve U to close the passage V accordingly. When for any reason the steamsupply is shut off from the valve U, it of course immediately opens wide, but its travel is here stopped by the action of rod T with one of the toes in connection therewith, in the manner set forth in thegeneral description.
Claim. I claim- The combination of the hollow shaft A and I shaft M, arms 0 0, balls N N, and valve U,
all constructed and arranged as and for the purpose set forth.
