MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 339,620, dated April 13, 1886.

Application filed January 22. 1856. Serial No. l5/19,436. (No model.)

To @ZZ whom t may con/cern.-

Be it known that we, GEORGE CnoMr'r-ON and HORACE WYMAN, both of Worcester, county of Vforcester, and State of Massachusetts, have invented an Improvement in Mechanical Movements, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a mechanical movement whereby a main lever may have one of its endsrplaeed in six different positions and be retained in any one of its said positions, the end of said lever being readily movable from any one to any other ofthe said six positions, the movementofthe end of the said lever from any one to any other of its six positions being made in the saine time.

In this invention a main lever of the first order has its `fulcrum upon acrosshar, the opposite sides of which have joined to it links, which at their other ends are jointed to levers of the Yfirst order, (preferably elbow-levers) in turn attached to connecting-rods actuated by crank-pins of toot-hed Wheels, the rear end of the said main lever having joined to it a link which is in turn joined to an elbowlever jointed to a connectingrod actuated by the crank-pin of a semi-rotating Wheel.

The particular features in which this inven tion consist will be hereinafter describethand pointed out in the claim at the end ol' this specification.

Figure l in elevation represents a mechanical movement embodying this invention; Fig.

2, a top or plan view thereof; and Figs. 3 to S, inclusive, are diagrams showing dilierent portions of the main lever.

The frame A, supposed to be part ol the frame oi a machine in which the mechanical movement herein to be described is employed, has a stud, Af, upon which are placed Wheels def, each provided with a crank-pin. llhese Wheels in practice will be toothed at their peripheries, and will be turned a semirotation in one and then in the opposite direction at the desired time by means of long gears, substantially such as described in United States Patent No. 281,842, dated July 24, 1883, to which reference may be had. The crankpin of the wheel d has attached to it a .Connecting rod, d', which is jointed to a lever, d, pivoted at '7. The crank-pin of the Wheel e is provided with a connectingrod, e', which is` pivoted to a lever, c?, having its fulcru n1 at 7. The crank-pin ofthe Wheel f has a connecting-rod,f, which is jointed to a lever, f2, pivoted atfa. One end oi the lever e has attached to it a link, g, and

one end of the lever f2 has attached to it a link, g. The opposite ends of the said links` g g support a cross-bar, g3, having a fulcrunistud, gi', upon which is mounted the main lever Iz, a lever ofthe tirst order, the rear end of the said lever having jointed to it at 8 a link, it', which in turn is joined at its other end to one end of the elhow-lever d?.

As herein shown, the outer end of the main lever It has jointed to it a slide-rod, h3, and the outer end of the said lever and with it the sliderod may be moved into any one of six positions designated by the numbers l 2 3 4. 5 6.

-Referring to Fig. 8, the main lever in full lines is shown at station l, and the crankpins of all the Wheels d c f' are at the left of the stud A.

To place the lever h with its end at station 2, as in Fig. 4. it is only necessary to partially rotate the wheel d and move the elhowlever 8c di'iuto the position shown in the diagram,

4L, and as in full lines, Fig. 1.

To place the end of the lever at station 3, as in the diagram Fig. 5, the Wheel e will be turned partially from its position, Fig. 4., to

place its crank-pin at the right of the stud A', and the wheel d will be turned to place its stud at the left of the said stud, the other wheels remaining as in Fig. 4.

To bring the end of the lever to'station 4 9c from the position shown in Fig. 5, both Wheels l d e will he turned io place their crank-pins at the right of the stud A", the wheel f having its cranlrpin le'tat the left, as in Fig. 6.

To place the end of the lever i at station 5,

IOC

from station 3 to station 5, (see Figs. 5 and 7 it is only necessary to partially rotate the Wheelf and place its crank-pin at the rightliand side of the stud' A.

Assuming all the crank-pins of the Wheels to be at the left of the stud A', as in Fig. 3, the end of the lever h then being at the station l, the end of the said lever may be immediately brought in one move to station 6 by simultaneously turning all the wheels d e f and placing their crank-pins at the right of the stud A.

In the diagrams the connecting-rod f is shown by full lines, the connectingrod e by a series of dots, and the connecting-rod d by a series of dots and dashes.

Among other things for which the mechanical movement herein described is especially applicable is the movement of shuttle-boxes in looms, or for the movement of a lever or rod Which for any reason is at times to have a variable throw or stroke.l

We do not broadly claim a cross-piece supported at both ends and supporting a longer lever having a link attached to it; nor do we broadly claim an elbow-lever and a link for one end of two levers.

We claimrlhree semi-rotating Wheels having crank pins, three connecting-rods, three levers of the rst order to which thay are joined, a link supported by each of the said levers, a cross-V piece connected with tWo of the said links and supporting a stud or fulcrum for the main Iever, combined With a main lever having its fulerum on the saidcross-piece and j oined to one of the said cranks, wherebyby the movement
