IMPRCVEMENT IN MECHANICAL POWERS.

Specification forming part of Letters Patent No. 161,753, dated April 6, 1875; application filed February 8, 1875.

To all whom it may concern:

Be it known that I, EDGAR CARY, of the city, county, and State of New York, have invented a certain new and Improved Mechanical Power, of which the following is a specification:

This invention is illustrated in the accompanying drawing, in which Figure 1 represents a side view. Fig. 2 is a similar view, showing the mechanism in a different position from that shown in Fig. 1. Fig. 3 is a front view of the same.

Similar letters indicate corresponding parts.

This invention relates to a device for converting continuous rotary into an intermittent rotary motion.

In the drawing, the letter A designates th driving-shaft, or any shaft to which a continuous rotary motion can be imparted. On this shaft is mounted a disk, a, in which is secured an eccentric wrist-pin, b. On the Wrist-pin swings a rod, B, which is guided in a box, 0, that swivels on a pin, 0, secured in the main frame 1), or on any fixed part, situated between the driving-shaft A and the driven shaft E. On this driven shaft is mounted a disk, F, which is provided with an eccentric cam-slot, f, and a stud, (Z,Whi0l1 is secured in the rod B, catches in this cam-slot.

When the driving-shaft is turned in the direction of the arrow marked on it in Figs. 1 and 2 of the drawing, the rod B assumes a sliding and a vibrating motion, being guided during its motion by the box C 5 and by the action of the stud d on the cam-slot f the shaft E is turned in the direction of the arrow marked near it in Figs. 1 and 2 of the drawing, until the disk F arrives in the position shown in Fig. 2. At this point the rod B moves in the direction of the arrow marked on it in Fig. 2, and the stud cl moves in the cam-slot without imparting any motion to the shaft E, while the driving-shaft A is turned without interruption. Therefore, the shaft E makes a partial revolution and then it stops during the time the stud d slides in the cam-slot f, as previously explained. length of time for which the shaft E stops depends in a great measure upon the position of the guide-box C, and by changing this position the motion imparted to the shaftE can be increased or decreased. When the position of said box is changed, however, the form of the cam-slot f must also be changed.

By this mechanism I am enabled to produce an effective feed-motion for various machines, such, for instance, as paper-cutting machines, and in order to accomplish this object, I mount on the shaft E a feed-roller, g, on which bears a presser-roller, h, and the material to be fed to the cutting-mechanism or to any other mechanism on being passed through between these two rollers receives a regular feedmotion.

What I claim as new, and desire to secure by Letters Patent, is-

The combination of the rod B, swivel guidebox 0, eccentric wrist-pin b, shaft A, slotted cam F, and shaft E, all constructed and op erating substantially in the manner herein shown and described.

In testimony that 1 claim the foregoing, I have hereunto set my hand and seal this 29th day of January, 1875.
