IMPROVEMENT IN AUTOMATIC GOVERNORS.
Specification forming part of Letters Patent No. 123,911, dated February '30, 1872.
. of Machinery; and we do hereby declare that thefollowing is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification,
and to the letters and figures of reference marked thereon.
Figure 1 of the drawing is a representation of a central vertical section of our invention. Fig. 2 is a modification of the same.
This invention has relation to certain improvements in means for regulating automatically the speed of machinery; and it consists in the construction and novel arrangement of the governor, the threaded valve-shaft, and their connecting-gear, as hereinafter described.
In the accompanying drawing, the letter A designates the sleeve of the governor; B B, the arms thereof pivoted to the arms a a of the sleeve, and provided with weights 1) b,- O, the shaft of the governor, on which the sleeve A revolves. This shaft is provided with a grooved collar, 0, for the engagement of the tips of the weighted levers B B. D, the power-shaft with its beveled gear. E E are bevel-wheels arranged to face each other on the shaft 0, and designed to engage with the wheel F. These bevel-wheels are provided with crown-teeth e 6 designed to engage with the double crown-wheel G, which is rigidly secured to the shaft 0. These connections are so arranged and regulated that, when the engine is runningat the proper rate of speed, the double crown-wheel G will play between the face-teeth of the bevel-wheels E E, engaging with neither. If the speed of the engine is decreased the wheel G will be raised and will engage with the upper wheel E. If the speed be increased the wheel G will descend and engage with the wheel E. H represents the valve which regulates the steam supply; The valve-casing I is provided with a number of openings, h h, corresponding with the disks k 70 of the valve. The valve-shaft K is provided with a screw-extension, L, which plays in a female screw in the center of the bevel-gear M, which receives its motion from the shaft f of the wheel F. This shaftfturns in opposite directions, according to the engagement of the double crown-wheel G with the upper or lower of the bevel-wheels E E. Hence it is evident that, as the speed of the engine decreases, the upper wheel E will turn the shaft f and the screw-gear M in such a direction as will cause the screw-shaft L to rise, opening the ports of the supply-valve. An increased speed will cause the shaft f to turn in the opposite direction, lowering the disks of the valve and decreasing the steam-su ppl y. When the engine is running at the medium or required rate of speed there will be no movement of the valve-stem. A groove, m, and stud n are employed to keep the screw-shaft L from turning, when required by the construction. The screw or thread upon the valve-stem K, which is one of the main features of our invention, may be constructed upon any portion of the stem. The female screw or nut need not necessarily be constructed so as to revolve in or. der to raise and depress the stem; on the contrary the nut may be stationary, and the screw or valve stem itself may be made to revolve, the nut P being stationary, and the stem, revolving with the gear M, kept from turning in the gear by a spline, n, and groove m. By the latter arrangement the female screw or nut may be constructed or located at any conven ient point in the length of the thread, or may constitute a portion of the valve casing, through which the screw upon the valve-stem can work; our main object-being to construct a portion of the length of the valve-stem in the form of a screw, so that reciprocal motion may be communicated to the valve or cut-off, as the case may be, either by rotating the nut through which the screw works, the screw at the same time being prevented from revolving by means of any suitable device, or by rotating the valve-stem or screw itself, the nut remainin g stationary.
\V e do not desire to confine ourselves to the precise method of construction herein described, as there are many Ways in which the In testimony that we claimv the (I-bO G We arrangement of the devices may be varied by have hereunto subscribed our names in the a competent mechanic. presence of two witnesses.
What We claim as our invention, and desire to secure by Letters Patent, is- CHARLES H. JONES.
