.To` a@ whom it may concern;

Beit known that I, JonANNEs EENsr MEYER, a citizen of Denmark, residing at Copenhagen,

in the Kingdom of Denmark, have invented` certain new and useful Improveinentsin Frio# tion-Clutches; and` I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to 1o make and use the same, reference being had to the accompanyingdrawings, and to the letters and figures of reference marked thereon, whlch form a partof this specication, and in which A Figure lis a longitudinal sectional view of a vertical shaft provided with my improved friction-clutch. Fig. 2 is a similar view of a horizontal shaft provided with the same, with a slight modification in the manner of attach- Fig. 3 is a cross-section on line 'y y, Fig. 2. y

Slmilar letters of reference indicate corresponding parts in all the gures.

` Myinventionhas relation to friction-clutches adapted to connect and to communicate motion from one rotated shaft to another, and it contemplates certain improvements upon a clutch actuated by centrifugal force, and particularly 3o adapted to couple that portion of the shaft of a4 centrifugal machine or other machine driven at high speed which receives its rotation from the motive power to that .portion to which the rotation is to be imparted, and it consists to 35 that end in the improved constructionv and combination of parts of such aclutch, as hereinafter more fully described and claimed.

-In Figs. l and 3 of the accompanying drawings is` shown the manner of attaching the Y 4o clutch upon a vertical shaft, which I will proceed to describe, the` construction shownin .Figs 2 and 4c being substantially the same,4

. y 5o verted conical bearings D, and the drive-pul ley is fastened at the point where the bases of through the same,while its upper edge is provided with an inward-bent flange, I, which fits close around sleeve B, above theY notches, ex-

cluding all dust and dirt from the clutch. It

will now be seen that as the sleeve B is rotated, the blocks G will be forced outward by the centrifugal force and press with their heads against the inside of the cylindricalbox H, and when, as the sleeve rotates, the centrifthe blocks upon the inner surface of the box becomes proportionally greater, rotating the box and the shaft with it, rst slowly, and gradually increasing, yso that it will be seen that the sleeve may be set in motion at high speed, and the shaft will first gradually assume the same speed, and it will likewise be i seen that if the sleeve is suddenly stopped `the blocks will recede from pressing against the inside of the box, and the box and shaft will continue rotating, gradually slackening in speed until their momentumlis spent.

In Figs. 2 and 4 the motive power is imparted to a shaft,J, forming` a continuation of shaft C, but separate from it, and the sleeve B is reduced in length, and keyed or otherwise fastened to shaft J, while the T-shaped blocks and box H are of the same construction, and

performthe same functions as in the construc= l Ation shown in Figs. 1 and 3.

If desired, springs may be inserted inside the shanks of the T-shaped blocks, which will cause the same to bear harder against the inside of the cylindrical box in starting;`but

s theiraction will be overcome by the centrifugal power, when a largeramount` of speed is obtained, when the springs will be forced outward, only acting by their weight, until in stopping the springs and `blocks will recede,

i the two cones adjoin, and may be made in one The lower -is fastened to the 'shaft C, which passes up ugal force becomes stronger, the friction of when the former, pressing the latter outward,

f will cause them to vact as brakes in gradually stopping the revolutions of axle C and its cylindrical box.

Having thus described my invention, 'I claim and desire to secure by Letters Patent of thc United Statesf l. A friction-clutch consisting of a series of T- shaped blocks, the outersurfaces of the heads of which form parts of a cylinder-sun face, sliding with their shanks in radial notches or recesses in a rotating sleeve or shaft, and a cylindrical box or easing fastened upon the shaft to be rotated, and inclosing and surrounding the blocks, as and for the purpose shown and set forth.

2. The clutch consisting of the rotating sleeve B, turning on shaft C, and having radial notches or recesses E at its lower end, blocks G, the shanks F of which slide in the Said recesses, having outer bearing-surfaces forming parts of a cylinder-surface, and cylindrical box H, fastened upon shaft C, as and for v the purpose shown and set forth.

3. The combination of the rotating sleeve B, having radial recesses E, T-shaped blocks G, the heads of which form partsof a cylindersurface, and shaft C, having cylindrical box H, having inwardly-bent annular flange I, as and for the purpose shown and set forth.

4. The combination of the double conical sleeve B, turning .upon shaft G inI inverted conical bearings D, having drive-pulley A, and radial notches or `recesses E at its lower end, T-shaped blocks G, and shaft C, having cylindrical box H, as and for the purpose shown and set forth.

In testimony whereof I have hereunto affixed my signature in presencel of two witnesses.
