CLIPPING 'SHEARS.

SPECIFICATION forming part of Letters Patent No. 448,170, dated March 10, 1891. Application filed March 26, 1389. Serial No. 304,910. (No model.)

To all whom it may concern.-

Be it known that I, LOUIS G. ERNER, a citizen of the United States of America, residing at Des Moines, in the county of Polk and State of Iowa, have invented an Improved Clipping-Shears of which the following is a specification.

My invention consists in the construction and combination of an adjustable comb, a re- 10 ciprocating cutter, and mechanism for transmitting and converting motion with a handle, as hereinafter set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which Figure 1 is a bottom view of the handle,

from which parts are broken away to disclose the mechanism for transmitting and converting motion combined therewith. Fig. 2 shows a piece of the handle and a swiveljoint connection between part of the operative mechanism and the handle. Fig. 3 is a side View of the complete machine. Fig. at is a corresponding side view, from which parts are broken away to show the bell-crank and cutter and a device for adjusting the comb. Fig. 5 is a perspective view of the machine.

A is a straight fiat metal handle that has an integral concavo-convex enlargement B at its front end adapted to inclose a bell-crank and to support a comb and a cutter. At its rear end it has an elbow-shaped enlargement 0, adapted to support arotating shaft. This shaft-support may be integral, as shown in Fig. 1, or connected by means of a swiveljoint, as shown in Fig. 2, so that the handle can be more readily turned with the operators hand as required to direct the cutter relative to the variable inclinations of the surface to 0 be traversed by the cutter.

d is a bell-crank pivoted in the enlargement B by means of a screw cl, as clearly shown in Fig. 4.

d is a rotating shaft extended through a 5 bore in the extension 0. It has a pulleyf on its outer end and a crank f on its inner end.

g is a rod that connects the crank f with.

the bell-crank d in such a manner that when the shaft is rotated the bell-crank will be vi- 5o brated. hen the extension O has a swivel connection with the handle A, a universal joint g is formed in the connecting-rod, as indicated in Fig. 2.

h is a cutter-plate of common form, that has 5 5 grooves h in its top face that admit projections 72, at the corners of the enlargement B to enter and to guide the motions of the plate when it is reciprocated by the vibrating bell crank, which has a projection i that enters a corresponding opening in the top and. center of the plate h.

m is a comb adapted in form to fit against and to close the open under side of the enlargement B, which enlargement has hooks 6'5 m formed on or fixed to its edges in such a manner that the rear end of comb can be pushed over the hooks, so'that they will hold the comb and also serve as fulcrums, upon which the comb can be adjusted as required to regulate the friction of the sliding cutterplate 6.

r is a screw extended downward through a bore in the metal handle.

0* is a coil-spring in the bottom of the same bore and under the end of the screw and in contact with the top of the rear end of the comb m. By means of the screw the pressure of the spring upon the comb can be readily regulated as required tocontrol the tension and friction of the reciprocating cutter.

8 are wooden coverings fixed to the sides of the metal handle. it

.2 represents a belt on the pulley f, through 8 5 which power and motion are transmitted from a suitable motor to rotate the shaft cl, and thereby actuate the rod g as required to operate the cutter h by means of the bell-crank.

I am aware that clipping-shears have had 0 adjustable combs and tension devices and gearing combined therewith, thereby adapting them to be attached to and operated by a motor; but my manner of forming a handle with an enlarged recessed front end and a tubular lateral extension at its rear end and combining a bell-crank, a cutter, a comb, and having a crank on its inner end, and a rod g, a rotatlng shaft therewith is novel and greatly having a universal joint g, arranged and com- TO advantageous. bined in a clipping-shears, substantially as I claim as my invention shown and described, for the purposes stated. The handle B, having a recessed enlarge- LOUIS G. \VER-NER.
