MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent Ila 253,798, dated February 14, 1882. Application filed January It, 1882. (No model.)

To all whom it may concern:

Be it known that I, RUEL W. WHITNEY, a citizen of the United States of America, resid-' ing at New York, in the county of New York and State of New York, have invented a certain new and useful Mechanical Movement; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawing, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to means for converting an eccentric rotary motion into a concent-ric rotary and a secondary oscillating and reciprocating motion; and it consists in a certain arrangement and combination of devices, as hereinafter more fully described, and spe citlcally set forth in the claims.

The object of my invention is to produce from the rotation of any power-driven shaft the rotation of a second shaft and the oscillation, vibration, or reciprocation of a third ele mentof machinery-in other words, to rotate a second element and vibrate a third element by the rotation of a first element of mechanismwhereby in any machinery adapted to perform any mechanical operation the two rotative and one reciprocative movements of the elements may be utilized in productive unitary or aggregate results.

In the drawing, which is a perspective of an arrangement of mechanical devices involving my invention, A represents the end of a powerdriven shaft. From the rotation of this shaft I desire to rotate the shaft B and oscillate a lever, U. The shafts are suitably journaled in the frame-work of any machine in which my invention is embodied, and the lever is pivoted to a fixed portion thereof. I obtain the desired results by the following means: To the shaft A, I attach in the usual manner an eccentric, D, to the shaft B a crank, E, and con Vnect the crank to the eccentric by a rod,'F. The lever U is attached to the frame-work by a pivot at G, and may be provided with trun. nions or bosses g at this point, if desired. Be-

low the pivot G, atH, I pivotally attach a connectinglink, J, which at its other end is in like manner attached to the rod F, at I. At K on rod F, I pivot-ally attach another connecting-link, L, which I may connect to a short arm or extension, 0, of lever O, at M, as shown; or I may connect said link L at the pivot G and discard the short arm or extension 0 of lever (J.

This being the arrangement of the elements employed, the operation is as follows: The rotation of shaft A causes through eccentric 1), a longitudinal and a lateral movement of that end of rod F which is connected to the eccentric, and these two motions are duplicated and merged into a rotary movement of said end of said lever during each revolution of the shaft. By and through the connecting-link L similar motions are produced, duplicated, and merged at the other end of rod F, and by and through crank E said rotary movement is communicated to shaft B. Thus the first step in the problem is accomplished.

It will be observed that the lateral movements of the ends of rod F are in opposite directions simultaneously; hence shafts A and B rotate in oppositedirections. Theseoppositelydisposed lateral movements of the ends of rod F produce a movement at about the center of its length which is similar to a movement resulting from oscillating a bar upon a rolling fulcrum at about its center. The pivot K of link L is such a fulcrum, the center of its rolling motion being about the center of the link lengthwise. Hence a similar rolling motion or oscillation must occur at the other end of link K, and I provide for this by the short arm or extension 0 of lever 0. Beyond the fulcrumpoint of rod F in either direction the movement thereof partakcs more of the rotary character than at said fulcrum-point, and this by means of the connecting-link J is communio cated to lever U, which, being fixed pivot-ally at one end, transforms said rotary movement into a vibratory, oscillatory, or rcciprocatory movement at its other or free end. Thus the second step in the problem is accomplished. 5 Now, it will readily be seen that the oscillation at the fulcrum-point of the lever F may be merged into its center, as that of the lever (J is at G. Hence I may-substitute for the link L and short arm 0 a link extending directly from pivot K to pivot G, and thereby produce the same resultant motions in shaft B and the free end of lever O.

The applications of my arrangement of mechanical elements as herein shown and described are, in themselves alone and in conjunction with subsidiary and additional wellknown elements, numerous.

In a sewing-machine, A may be the needlebar shaft, B may operate the shuttle, and G the feed, the usual or any well-known mechanical elements for the direction and transmission of power being added in a manner well known to persons skilled in that branch of mechanical structures; and so in planing, boring, drilling, sawing, shaping, and in all other machinery where material is fed regularly orirregularly and operated upon either continuously or intermittently the same arrangement may form the gist or basis of operation, and I should deem such application as within my invention and embodying the same, as I should also the simple reversal in position of my arrangement, when, as for instance, shaft B might be the needle-shaft of a sewing-machine, shaft A the shuttle-shaft, and lever 0 might operate either needle, shuttle, or feed, and still be an embodiment of my invention.

Having described my invention and its operation, whatI claim as new, and desire to secure by Letters Patent, is-- 1. The combination of shafts A and B and lever O and means, substantially as shown and described, for rotating shaft B and vibrating lever O by the rotation of shaft A, as and for the purpose set'forth.

2. The combination of a power-driven shaft, an eccentrically-connected rod attached concentrically to a second shaft and pivotally connected at two points to a pivoted lever, substantially as shown and described.

3. The combination of a power-driven shaft, an eccentrically-conuected rod, and a pivoted lever connected at t '0 points pivotally to said rod, substantially as shown and described.

4. The combination ofshaft A, eccentric D, lever F, links L and J, and pivoted lever O, substantially as shown and described.

5. The combination of sh aft A, lever F, shaft B, lever G, and connecting-links L and K, substantially as shown and described.

In testimony whereof I have affixed my signature in presence of two witnesses.

RUEL W. WHITNEY.
