IMPROVEMENT IN CLUTCHES FOR POWER-DRESSES.

Specification forming part of Letters Patent No. 164,690, dated June 22, 1875 application tiled May 10, 1875.

To all whom it may concern:

Be it known that I, ALANSON H. IVIERRI- MAN, of West Meriden, county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Punch- Iress Clutch; and to enable others skilled in the art to make and use the same I will proceed to describe it, referring to the drawings, in which the same letters indicate like parts in each of the figures.

In the accompanying drawings, Figure 2 is a sectional side elevation. Fig. 1 is a back end elevation; Fig. 3, top and end view of the horizontal sliding guide-groove.

My invention relates to an improvement in that part of a power -press known as the clutch, or device for connecting and disconnecting the power from the press when desirable.

A is the frame or body of the press, having proper bearings, into which is fitted closely and works freely a shaft, B, upon the front end of which is formed or secured a crank or wrist-pin, C, to which the slide or plate for holding the tool is attached, as shown in my patent, May 26,1868, No. 78,225. D is the d living-wheel, which is fitted closely and turns freely upon the shaft B next to the body or frame A. Into the hub of this wheel D is fitted a friction sliding dog-pin, E,which is held by a friction device from moving in either di rection, except when actuated by a horizontal concave sliding guide shoe-plate, F. Just back of the wheel D, upon the shaft B, is fitted a clutch-collar, G, secured to turn in uniformity with the shaft by a key, H. Directly under and pa allel with the shaft B is a bracket, I, having a V-shaped groove, into which is fitted closely and moves freely a sliding plate, J. On the upper side and outer end, and at right angles with this plate J, and directly under the wheel-hub, is the concave guide shoe-plate F,

the curve or section of a circle of which is a little larger than the diameter of the wheelhub, and the side guide 1 is formed inclineshaped, or diverging outward each way from the center of the plate F, and the guide 2 is formed at right angles with the shaft B two inches, more or less, directly under said shaft, and in diverging lines each way therefrom. This concave sliding guide shoe-plate F is actuated back by a foot-lever, a, and its connections b 0, which are supported or held in the brackets d c, and is reacted, when the foot is removed from the treadle, by a spring, f. The upper end of the lever-connection 0 passes through an elongated orifice in the plate I, into an orifice in the shoe-plate F, and is thrown outward by the foot-treadle or lever 61, and, when the foot is removed, is reacted by the spring f.

Now, it will' be clearly seen that the direction of the revolution of the wheel D is immaterial, thereby avoiding accidents, which otherwise are liable to occur; also, that when a full action of the press is had, and the foot removed from the treadle, the center of the crank or wrist pin 0 will rest at the highest point of its circle. Y

Thus I am. enabled to greatly simplify and produce quick and positive action of the clutch.

WVhat I claim, and desire to secure by Letters Patent, is

In a press, substantially as herein described, the wheel D, sliding pin E, collar Gr, key H, guide-plate F, bracket I, plate J, and springtreadle, all combined to operate substantially as herein set forth.

ALANSON H. MERRIMAN.
