UNITED STATES PATENT OFFICE.
FRANK ANDERSON, or PEEKSKILL, NEW YORK.
GOVERNOR.
SPECIFICATION formingpart of Letters Iraterit No. 267,965, dated November 21, 1882. Application filed September 7, 1882. (No model.)
.To all whom it may concern:
Be it known that I, FRANK ANDERSON, of Peekskill, in the county of Westchester and State of N ew York, have invented a new and useful Improvement in Governors; and I do hereby .declare that the following is a full, clear, and exact description of the same.
My invention is an improved governor, the object of the invention being to regulate the speed of the machinery to which it is applied,
. and at the same time to save the expenditure of power beyond that required to maintain a given rate of speed.
My invention is more especially designed for use in machines impelled by hand or foot power. r
The essential principle of the invention is that centrifugal force caused by speed in excess of that required acts upon a pressure piece or pieces and releases the driving-shaft from the driving mechanism, thereby relieving the driving-power of the work while the parts are so disconnected.
I Heretofore governors have been commonly used which operate by centrifugal force generated by rapid revolution, creating friction to consume the power in excess of that required; also, governors are commonly used which by centrifugal action shut ofithe energy or motive power, thereby reducing the speed by reducing the force applied to the machine. In my invention the governor determines the amount of force which it will receive from the motive power by letting go the grasp upon the communicating mechanism when a speed is attained boyond the determined limit.
In the accompanying drawings I have shown the best means known to me for carrying my.
idly attached to the shaft K, which communicates motion to the machine. The rim is made of the pulley. The pulley may be of any form convenient for the transmission of power, and it is to be connected by band or equivalent device to a treadle or. wheel to be operated by any power, as of the footer hand of the operator, as in telegraphic perforators, sewingmachines, and the like, or by animal-power, as in grain-separators and like machines. The rim Z extends into the cavity of the flywheel, and is of slightly less diameter than the inside of fly-wheel rim. Sections m m of the rim of 'the fly-wheel are cut out of the latter and are held in their position by the springs m m on the outside of the wheel. These springs admit of a slight outward movement of segments on m. On the inner side of the segments pieces of leather l or other proper material are placed, which project sufficiently to touch with some pressure the periphery of the rim 1 of the pulley, the pressurebeing insured by the action of the springs m m. It will be seen that if the pulley is revolved the friction between the rim of the pulley and the leather on segments m can bemade sufficient to cause the fly-wheel to revolve also; and it is also evident that as the speed increases the centrifugal action of the segments or weights will also increase till it equalsor overcomes the resistance of the springs, and the friction between the two surfaces will cease. Consequently the speed cannot be increased beyond a point where the centrifugal action relieves the friction, no matter how fast the pulley may revolve. The springs m 'm are made not quite strong enough to insure full speed, and are then re-enforced by the spiral springs m" m, the strain of which is easily regulated by set-screws which pass through thin slotted pieces into the segments, thereby clamping these pieces adjustably to the segment at l 1, thus affordinga ready means of adjusting the speed. I have shown two of the segments or pressure-pieces, but obviously the number is not material. Nor is it essential that the seg- ICO inents should be attached to a fly-wheel. Any intermediate wheel or support fixed to the shaft and holding the segments which bear against the rim of the pulley will serve the same purpose.
By the apparatus above described it will be obvious that an increase of speed above a certain determined limit disconnects the drivingpower from the mechanism to be driven, and thusat the same time reduces the speed and keeps it within a certain limit and relieves the driving-power of the work when the speed is in excess of the prescribed limit.
Havingthus described my invention, what I claim is- 1. An improved governor, consisting of a pressureipiece or pieces, connected by intermediate support to the shaft of the machine, a pulley or like'device for communicating motion, loose upon said shaft, adapted to receive the pressure of the pressure-pieces, and suitable springs to cause the pressure-pieces to bear upon the pulley, the parts being constructed and operating in relation to each other as described, whereby-increaseof speed beyond a 25 certain limit releases the pulley from connection with the shaft, substantially as set forth.
2. The combination, with the main shaft, of a fly-wheel fixed to shaft, pressure-pieces connecting therewith, and a pulley loose on said 0 shaft, the said pressure-pieces being adapted to connect the shaft to the pulley and to be released therefrom by centrifugal force, as set forth.
3. The combination of the fly-wheel M, shaft 5 K, pulley L, flange 1, segments m, and their springs, substantially as described.
In testimony whereoflhave signed myname to this specification in the presence of two subscribing witnesses.
FRANK ANDERSON.
