MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent N 0. 448,713, dated March 24, 1891.

Application filed July 14, 1890.

To all whom it may concern.-

Be it known that we, RICHARD LONGDEN HATTERSLEY and JAMES HILL, subjects of the Queen of Great Britain, residing at Keighley, in the county of York, England, have invented an Improvement in Mechanical Movements, of which the following description, together with the accompanying drawings, is a specification.

This invention has for its object the formation and disposition of two series of levers and their respective shafts and connectingrods for the purpose of effecting, when put into operation, by series of hooked jacks mounted upon one of these series of levers being made or allowed to engage with reciprocating draw and push bars, the movements of a third series of levers in a positive manner, as also the looking or rigidly holding of this said third series of levers at each extremity of their movements, so that any force acting through this third series of levers when they are at the said extremities of their movements is withstood by several stationary shafts, upon which said several series of levers are mounted. The particular uses for which these devices are fitted are the operating of the heddles or the shuttle-boxes of looms for weaving, and the usual and wellknown connecting parts are employed for connecting these said mechanisms to those of said looms.

The object of our invention is attained by the mechanism illustrated in the accompanying drawings in which- Figure 1 is an elevation of the parts shown as mounted upon a board or panel A instead of upon the ordinary frame work, which would have interfered with the clearness of the View. Those parts of the mechanism which in an ordinary way would extend across from the frame-work on one side of the machine to that 011 theother are here shown in section. Fig. 2 is a top view of parts shown by Fig. 1; and Fig. 3 is a similar view to Fig. 1, but shows the relative positions of the several parts when moved soas to bring the third series of levers a to the other extremitiy of their movement than that shown by Fig. 1. y

In all the drawings, in order to simplify the serial No. 858,613. (No model.)

view, only one lever, together with its several parts, out of each of the three series of levers is shown, as from this it will readily be seen how the remaining parts of each series are to be arranged.

Similarletters refer to similar parts throughout the several views.

The lever (it represents the series of levers herein referred to as the third series, and is shown as being mounted upon its shaft b by spanning the same, so that when its retainingrod 0 is removed it may be readily detached at the time it is forming one of the series without in any way disturbing or displacing any other in the same series. The levers d and e representthe two other series of levers,

the same being mounted upon the shafts f and g, respectively, and coupled together and to the lover a by the rods h and k. The hooked jack Z is coupled to or made to lay hold of the pin an, attached to the rod h, and is made to extend horizontally tobe in proximity with the draw and push bars at and n, to or from which they are made to lay hold or to be clear of by means of the peg-lags or pattern-surface 0 on the pattern-cylinder 19, operating same in the well-known manner through the lever r. The draw and push bars n and n are reciprocated by the rodst and 25', (shown in broken lines, Figs. 1 and 3,) being coupled thereby to the oscillatory lever to, which receives its oscillatory motion through the rod 4) from any suitable motor, such as a crank attached to or formed on a rotary shaft driven by any prime motor.

Now, when the rod h has been moved by the jack Z into the position shown by Fig. 1 said rod It will have moved the lever d into the positi on forthe center of its pin 62' and that of the pin 71/ on said rod h to be in line with the I center of the shaft f, in which position the lever 6 and the rod 70, as also consequently the lever a, (the position of which is now at the extremity of its onward 'movement,) will be locked or rigidly held by reason of these several centers being in line with each other, while when the rod h has been moved into the position shown by Fig. 3 the lever e and the rod is will have been thereby moved into the position for the center of the pin is on the rod is and that of the pin a on the lever a to he in line with the center of the shaft g, in jack Z, the bars n and n, the rods 25 and If, to which position said lover a (which has now and the lever u,in eombination,all these sevreached the other outward extremity of its eral parts being mounted, constructed, and movement) will be locked or rigidly held arranged tooperate substantiallyas specified.
