IMPROVE-b FEED-MOTION;

The Schedule referred to in these Letters Patent and making part of the same. a

To all whom ital/a4; concern:

Be it known that I, ALFRED J. SHIPLEY, of the city of Waterbury, in the State of Connecticut, have invented an Improved Feed-Motion for machines for cutting the teeth of metal combs; and I declare the following, taken in connection with the drawings acsufificient tofenable experts to make and use the same.

The nature of my improvement consists in an adjust facility from long strips of sheet-metal.

' The drawings show In Figure 1, a press with all the parts inviewin perspective.

In-Figure' 2, a comb.for reference-cut in a strip. of

An ordinary press, A, has a cutter, a, suitable to the required teeth of the comb, working into a die be The strip'of inetal'prepared to the width needed for the size] of the intended comb, passes through the guide 1), between a pair .of feed-rolls, c c, which could, if re-- quired,g'be used to emboss the metal inpassing- The rolls are driven by the gear 11, which,is seen working in another wheel, on the shaft of the lower feed-roller, as shown by dotted lines.

On the same shaft are two ratchet-wheels, e and f, The larger one, c, has a notch for a tooth in the comb, and is-dn'ven by the pawl g on the lever h, whose fulcrum is on the shaft that drives the lower feed-roll c, Said lever being attached to the rod i, is moved by an ,ec-

centric, j, shown by dotted lines on the main shaft of v being provided with one indentation, when the circumference of the wheel is equal to the required length of a comb, or more indentations, when a larger wheel is used. The drawing shows two, 1, 2.

The pawl m, on the lever n, is moved by the rod 0, which is attached to an adjustable slide, 1), in the crankrface plate 1', so that by lengthening or shorteningthe stroke of the crank, the ratchet-wheels and feed-rolls will set themetal strip forward any' required distance, to'fo'rln suitable ends to each .comb.

I am aware that to operate a pair offeed-rollers by means of a crank or eccentric, through'the medium of a connecting-rod, ratchet, and pawl, is not new, and I do not claim these devices, nor their combination; but

I What I do claim as of my invention, is+.-

Combining, with the aforesaid combination of devices, an-auxiliary set of devices, for imparting, at intervals,

a feed-movement of accelerated velocity, and of greater extent than that imparted by the aforesaid combina-
