Letters Patent No. 108,162, dated October 11, 1870.
IMPROVEMENT IN GOVER-NORS FOR STEAM-ENGINES.
The Schedule referred to in these Let-ters Patent and making part of the same the construction and operation of the same, reference being had to the annexed drawing forming part hereof. A
The object of' this invention is to obtain the greatest possible sensitiveness of action, whereby the least change of the engines speed shall be instantly responded to, and a uniform motion, or nearly so, maintained, irrespective of the sudden change of load or resistance.
Also, to provide a passage for steam through thev mechanism and Also, to provide a safety-governor, which, if arrested in its motion, the speed of the engine will still be limited by it.
The first object of my invention is accomplished by the combination and arrangement of the three weights or balls and the cam mechanism in the head ot' the governor.
The second and third objects are accomplished by the construction and arrangement of the valve and its case, and the devices for setting the balls in the desired position for eiiicient action of the cri-ordinate devices. r
Referring tothe drawing- Figure l is a sectional front elevation. Figure 2 is a side elevation, in section, of the governor-head.
A and B represent weights, which are attached, by arms F F, to the ends ot shaft C, which shaft is actuated'by them.
To the center of shaft C is securely attached the cam D, which raises and depresses the arm E, to
' which the valve-.rod G is iirmly secured.
The guide-hinge H is the same length as the cam D between centers of motion, and the hinge is hung to the bracket I, in a parallel line to cam D, so
-that there shall be no bind in the motion, but, on the.
contrary, the movement must be harmonious.
The vhole in the arm'E is elongated, so that the connecting-pin between I) and E is allowed a little horizontal motion, it' required.
lThe ring and arm J are made adjustable, and performthefunction of stopping the weight B at the proper vplace in its descent, and thus prevent any strain which would injure the immediate mechanisln.
The valve-rod, d1'iving-gear,aud weighted lever are about the same as those -in common use in many governors.
K is a double disk hollow valve, with enlarged hole at the top, to admit the coupling for the valve-rod.
rIhe holc through the valve is as small as practicable, so that the center of the valve shall occupy the least possible room.
The guide-wings Lextend the whole lengh of the space between the disks. .A
The body N has four seats, O20 O Of", situated at proper distances from each other, so that the upper disk ot' the valve can move from the bottom of Ov to the top ot' O', while the lower disk will act in the same manner with reference to the seats O O.
rIhis construction allows all the steam, to the full capacity of the steam-pipe, to pass through free-ly.
The space around the upper disk, between O and O', is only sufficient to allow as much steam as--can freely pass down through the valve, and threby preventing a downward steam-pressure on the valve.
rIhe drawing represents the governor motionless. When power is applied to Jche pulley, giving the proper motion, the rotating movement will cause weight B to rise, whileweight Awill fall in like proportion. rIhe shaft -C is turned, and the valve is clepressed in due proportion to the speed given. If the speed is too great, the aperture will beentirely closed, by the disks coming in contact'with seats O and 0". 1f the motion ceases, the aperture will again be closed by the disks coming in contact with seats'O and O",
which', in practice, would avoid accidents incident to the full steam-pressure being let on at once.
As' the weights or balls A and B 'are of unequalV weight, it may be found, in practice, necessary to ball ance them, by hanging a small, ball or weight opposite to weight A. Figures 3 and 4 show another construction of valve and valve-case, which may be preferred 'in governors of very large capacity'.
The lower end of this valve and case are of the same construction as shown in tig. 1. The upper end of the valve, shown in gs. 3 and 4, is cylindrical, and is provided with a series of holes.
Then the governor is in full operation, these holes are opposite to and receive steam from the 'annular'- passage T, which is connected to the steam-chamber by the hole U.
Then the valve -is pushed down, the holes will be covered by the lower ofthe two upper seats. i XVhen the valve is raised, the holes will be covered by the upper seat. 'lhus will the valve-openings be closed when the valve is at its `lowest and highest point.
It is not necessary that the'governorvalve should entirely close the steam-passage, but, ou the contrary, such practice is productive of delay and inconvenience. The ring and arm J J obviate this difficulty, by being adjusted so that the weights or balls are limited ln the range of their` descent, whereby the engine may be. allowed to continue its maximum speed even though the governor-belt should break, or in otherwise the governor-mechanism become deranged.
Having thus described the nature of my invention, What I claim :is new, and desire to secure by LettersPatent, is-
1. The adjusting-ring and arm J J. 2. The combination and arrangement of the unequal weights A and B and shaft G, whereby the ymotion of the Weights shall act in harmony on the shaft C,- substnntizdly as herein described.
