SPECIFICATION forming part of Letters Patent No. 662,569, dated November 27, 1900.

Application iiled April 13, 1900.

To all whom t may concern,.-

Be it known that I, WILLIAM K. Loan, a citizen of the United States,residing at Mount Carmel,in the county of Northumberland and new and useful Improvements in Speed-Regulators, which improvements are fully set forth in the following specification and. accompanying drawings.

In the drawings, Figure l is a View in elevation of a speed-regulator embodying my said improvements. Fig. 2 is a view similar to Fig. 1, a portion of the parts being shown in section. Fig. 3 is an elevation view showing the dial with its coperating pointer which I make use of.

Similar reference numerals denote like parts throughout the several views of the drawings. j.

This invention relates, in a general sense, to improvements in devices of that class commonly known as speed-regulators or governors,7 and more particularly to speed-regulators having special utility in connection with phonographs, metronomes, and analogous mechanical structures.

The object of my invention is to provide a speed-regulator which shall be simple and cheap as regards construction, positive and efficient in operation, which shall embody in its construction means for speed indication, and which shall possess palpable advantages over prior analogous devices.

The invention consists in the employment of certain novelty-formed parts, in the novel disposition and arrangement of the various parts, in certain combinations of the latter, and in certain details of construction, all of which will be specifically referred to hereinafter.

Having reference to the accompanying drawings, 2 2 denote frame portions. rlhe shaft 3 is journaled at one end in the frame portion 2', and at the other end said shaft is' provided with an extended journal 3', which bears rotatably in the crown of the inwardlyturned cup 4, the latter being disposed within a suitable opening formed in the frame portion 2 and having adjustment to and fro within said opening and longitudinally with respect to the shaft 3, the latter adjustment Serial No. 12,698. (No model.)

of said cup being made permissible through the employment of the extended journal 3.

To the end that the cup 4E may adjustably occupy the opening with which the frame portion 2 is provided I prefer to provide the annularV wall of said cup with suitable eXterior threads adapted to engage corresponding threads formed in the wall of said opening, so that the cup Il may he adjusted with respect to the frame portion 2 after the manner of a screw.

5 denotes a bracket or disk fixed on the shaft 3, and 6 is a friction-disk loosely mounted on said shaft, the said bracket 5 and friction-disk 6 being connected by the opposing semi-elliptic springs 7, each of which carries a regulator-ball 3. The friction-disk 6 has a boss or extension 6', which carries a minor friction-disk 9, the latter normally within the cup 4.

l0 is a friction-disk which encircles the eX- tension 6 between the friction-disk 6 and the minor disk 9 and is fixed in any approved manner to the inner surface of the annular body portion of the cup al.

The frame portion 2 is provided with a dial, as illustrated in Fig. 3 of the drawings., and for cooperation therewith I fix to the cup 4 a pointer 1l.

A rotary motion may be imparted to the shaft 3 through the medium of the pinion l2, fast on said shaft.

To obviate the noise incident to the engagement of two metallic parts, I form the disk 6 and minor disk 9 from indurated fihler or material analogous thereto in degree of hardness and the disk l0 from suitable sheet metal, or the latter may be formed from indurated fiber or material analogous thereto in degree of hardness and the disks 6 and 9 from suitable sheet metal.

In operation upon the shaft 3 attaining a certain degree of speed the regulator-balls, through the action of centrifugal force, contract each its cooperating spring, thus bringing the disk 9 into frictional contact with the disk 10, with the result of retarding the speed of the shaft 3. The lateral position of the disk lO in respect to disk 9 being determined by the rotation of cup 4 and its pointerll, it necessarily follows that the position of the IOO pointer 1l on face of instrument will denote the speed of the shaft 3. Under a decreased speed of the shaft 3 theregulator-balls act to distend each its cooperating spring, thus bringing the disk 6 into frictional contact with the disk 10. This action of disks 6 and l() would only be used by having threads of cup 4 engaging loose enough in frame 2 for the frictional contact of disks 6 and 10 to rotate cup 4 backward out of contact and not loose enough for thev frictional contact of disks 9 and l0 to affect saine. This action, then, would indicate itself on the dial as the regular maximum speed of shaft 3. By moving the pointer llto any less indicated speed the frictional contact of disks 9 and l0 will regulate it at that speed. I may also pivot shaft 3 in frame 2 and place cup 4 to one side of same, but near enough so, by increasing the diameter of the disk 10, it will engage the disks 9 and 6, as before.

It is obvious that my improved speed-regulator may be modied to some extent, particularly as to the form of any of the parts and as to the details of construction, without materially departing from the spirit and principle of my invention.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a device of the vclass described, the combination of a suitable frame portion, a cup-like element supported by said frame portion, adjustable with respectl thereto, a friction-disk at its inner surface, a frictiondisk within said cup-like element, and means for effecting frictional contact of the lastnamed friction-disk with the iirst-named friction-disk, as herein specified.
