IFCOIFICATION forming part of Letters Patent No. 347,294, dated A Application filed December 2!), 1885. Serial No. lat L000.

To @ZZ whom it" 722/111, concern:

Be it known that l, URI HAskiN, a citizen of the United States, residing at McDonald, in the county of l'Eradley and State of Tennessee,

5 have invented certain new and useful Improvements in Mechanical Movements; 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 IO it appertains to make and use the same.

My invention relates to mechanical movements; and it consists ofa device,as hereinafter described and claimed, for giving to machinery an intermittent or periodical movemeat.

My invention is adapted to that class of machines which carry dies on a revolving disk such as rivet or spike machines or stop-gears in which it is desired to present the dies car- 26 rying the object to be operated on to separate cutting, shaping, and heading mechanisms at uniform intervals.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a view in elevation; Fig. 2, a plan, and Fig. 3 is a detail.

B E are what are sometimes called starwheels, and are divided into concave arcs Ii 30 by means of radial slots 9, the bottoms of which slots are rounded. These wheels are secured to shafts which are inclosed in sleeves c o,mounted on pillow-blocks u c,arising from the bed-frame.

at the point of the crank O, between it and the disk I, is attacheda friction roller or pin, L. in operation, the friction roller or pin L is adapted tio'cnter one of the slots as the lat 5 ter is inclined toward it, so that in both entering and leaving the slot the roller or pin passes overan inclinc,which results in a gradual starting and stopping of the wheel, and renders the machine comparatively noiseless 5o inoperation when running at a high speed.
