IMPROVE MENT IN AUTOMATIC STOP-MOTIONS.

Specification forming part of Letters Patent No. I 73,537, dated February 15, 1876; application filed January 27, 1876.

To all whom. it may concern Be it known that I ,'AUGUSTUS A. HAGEN, of the city, county, and State of New York,

have invented a new and Improved Automatic Stop-Motion, of which the following is a'specification Figure 1 represents a top view, Fig. 2 a side view, and Fig. 3 a vertical transverse section, of my improved automatic stop-motion for feed devices. 7

Similar letters of reference indicate corresponding parts.

The object of my invention is to provide an improved automatic stop-motion for feedwheels in tobacco cutting and other machines; and it consists of a fulcrumed lever, that operates, by contact with a raised part of the feed-screw, a transverse slide-piece, and, by a connecting swinging slide, the spring-pawl of the ratchet teed-wheel, so as to throw the same out of gear. v s

In the drawing, A'represen ts the feed-screw of the follower of a tobacco-cutting or other machine, which may be turned forward orbackward bya hand-crank, B, at the outer end. The hand-crank B is provided with a raised flange, a; or any other equivalent contact device may be arranged on the feed-screw, to be brought in contact with a lever, (J, fulcrnmed to the swinging arm D, that, by its spring-pawl E, operates thefeed ratchet-wheel. When the follower is to be fed forward, the feed-screw A is secured, with a flangeor other contact-stop, a, in upright position by a pin, 1), of the follower, thatlocks the feedscrew'against lateral motion, but allows, by the turning of thefeed-ratchet, its forward motion in longitudinal direction. To theend of the fulcrumed lever O is pivoted the transversely-sliding link F, which moves in a guide-hole of the oscillating arm D,

and engages, by an inclined recess, d, the recessed slide-piece F, that is, guided by side flanges and stop-pins along the swinging arm D. A spring, cl, set into a recess of arm I),

the same forward, when the slide-link F is withdrawn, by pressure on the fulcrumed lever, the inclined recess d admitting then the easy motion of the slide-piece F, so that it bears against the springpawl, and throws the same out of the teeth of the ratchet, and I interrupts instantly the forward motion of the feed-screw A. By withdrawing the stop-pin b, that fastens the feed-screw to the follower, and screwing the' follower back with the handcrank, the fulcrumed lever may be set again by carrying the arm of the same that was in contact with the stop away from the swinging arm. This carries the slide-link at the opposite end of the lever forward again, so that the incline of its recess forces the pawl-gov erning slide-piece back, causing thereby the release of the pawl, and its re-engaging of the teeth of the ratchet-wheel. The forward feeding of the screw by the oscillating arm is automatically interrupted when the stationary stop of the feed-screw bears on the 'fulcrumed lever, which causes the throwing out of the pawl to interrupt the feeding at the exact moment required. it Having thus described my invention,I claim as new and desire to secure by Letters Pat- Gilt- I 1. The combination, with a fixed flange or contact-stop of the feed screw, of a fulcrumed lever of the oscillating arm, said lever producing the disengaging of the ratchet operating pawl, to interrupt the feed-motion of the screw, substantially as specified.

2. The combination of the fulcrumed lever O and the transversely-sliding link F, having inclined recess d, with the perforated and spring-acted slide-piece F and the spring-pawl E of the oscillating arm, to raise or drop the pawl by motion of lever, substantially as described.
