IMPROVEMENT'IN APPARATUS FoR TRANSMITTING MOTION.

June 20, 1874.

- Specification forming part of Letters Patent No. 59,293, dated J anuary 530, 1866; reissue No. 2,615, dated May 14, 1867 reissue No. 5,476, dated July 1, 1873; reissue No. 5,97l, da ted July 14, 1874; application filed 'dina and State of Ohio, but now res'idingfat Benzonia, in the county of Benzie and State of. Michigan, have invented certain new and useful Improvements in'Apparatus for Tran smitting Motion, of which the following is a specification "Theobject of my invention is so to transmit power from a prime mover to an operating instrument that the latter may freely be moved in any direction, to enable it to operate at any desired angle relative to its driving-sh aft with out disturbing its connection therewith, which end I attain by interpos'ing between a rotating power-driven shaft, from which the power is conveyed to the instrument itself, and an instrument free to move in any direction, a spiral spring or flexible shaft of coiled wire. The subject-matter claimed is hereinafter designated.

In the accompanying drawings, Figure 1 represents a view in perspective of so; much of an apparatus embracing my improvements as is necessary to illustrate the invention herein claimed, the machine shown being an apparatus for shearing sheep. Fig. 2 is a detail view, partly in section, showing the connection between the flexible shaft and its driving mechanism. Fig. 3 represents a vertical longitudinal central section through the instrument on the line a: a; of Fig.1 4, showing the connection betweenthe flexible shaft and the instrument operated by it. Fig. 4 represents a top-plan view of the instrument itself, and Fig. 5 a bottom plan thereof.-

A band-wheel, B, driven by a crank, b, or in any other equally well-known way,'is mounted ona shaft, al, in bearing supported in a frame or stand, A. An endless band or belt, F, passes from the band-wheel B around a pulley, E, the shaft of which is mounted in bearin gs .in an arm, 0, pivoted upon the shaft aof the band-wheel. One end of a spiral spring, G, of steel, cop-per, or other metal most suitable for the purpose, is connected with the shaft or journal 0 of the pulley E. To the other end of this springis attached a stub, g,-through which motion may be imparted to the instrument or tool to be actuated. The stub g, in this instance, turns in hearings in a handpiece or casin g, G, and has a crank-wheel, H,

mounted upon it. A crank-pin, h, on this wheel works in the slot 11 of a tail-piece or rocking lever, I, which is oscillated on a pivot, i, by the rotation of the crank-pin. A vibrating cutter, J, issec'ured on this pi;vot,and is h caused by its oscillations to shear over a series of fixed guards or knives, Kyon the casing.

By the method of construction above described, the operator is enabled to move the instrument in all directionswith the greatest facility.

The stand upon which the mechanism is mounted, it will be observed, is portable, and

' has a comparatively wide base, to prevent its toppling over. The upper end of the stand is forked, so as to include the band-wheel, and

support its shaft at both ends. The pulleyarm 0 is also forked, and connectedwith the stand on each side of the band-wheel, in order that the arm may be more firmly braced, and to avoid unequal strain on on e j side of the bearing'of the shaft a. The end-,of'thearm C opposite to that which carries the pulley E extends beyond the shaft 01, and is connected with the frame by a spring, D, by which means the pulley-arm and its attachments are counterbalanced and held at the Neither do I claim herein the details of the,

shears, or the combination of the driving mechanism with said shears, as this feature forms the subject-matter of another division'of my original patent, and is numbered, reissueNo;

The combination of a rotating powerdriven shaft, a flexible, coiled-wire shaft, conneeter f my own invention cured to its other end'an instrument free to be moved by hand inany directionwithont interru iting the transmission --of the power members being" construetedto thereto, these operate in combination, substantially as set forth.

2. The combination of a porta rotating power-driven. shaft mounted therein,

and a flexible coiled-wire shaft, connected at one end with the power-driven shaft, and at the other with-an instrument free to be'moved in any direction by the hand of the operator without interrupting the transmission of the power, these members beingconstructed to:

operate in combination, substantially as set forth.

-3. The combination oia portable stand; an

arm pivoted upon the 'shaft'of a band-wheel."

mounted upon said arm, and a flexia pulley e end ble c0iled= wire shaft; connected at m with the pulley-shaft, and at the other. with an instrument free tube-moved in any direction by the operator, these members being 1 atone end with the power-driven s'haft, suspended freely therefrom,- and'having se-' ble stand, a

constructed to-bperate in combinatiom substantlally as set forth.

4. The combination of 1 a rocking arm, a

ble shaft connected therewith for transmit; ting power, and a counter-balance .toiuphold operate in combination, substantially as set '-forth.
