MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 448,714, dated March 24, 1891. Application filed July 14, 1890. Serial No. 358,614. (No model.)

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 certain 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.

WVe attain the object of our invention 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 Ainstead of upon the ordinary frame-work, which would have interfered with the clearness of the view. Those parts of the mechanism whichin an ordinary way would extend across from the framework on one side of the machine to that on the other are here shown in section.

Fig. 2 is a top view of parts shown by Fig. 1;

and Fig. 0 is a similar view to Fig. 1, but shows the relative positions of the several parts when moved so as to bring the third se ries of levers a to the other extremity of their movement than that shown by Fig. l.

In all the drawings, in order to simplify the 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.

Si milar letters refer to similar parts throughout the several views.

The lever a represents the series of levers herein referred to as the third series, and is shown as being mounted upon its shaft b by spanning same, so that when its retaining rod 0 is removed it may be readily detached at the time it is forming one of the series with out in any way disturbing or displacing any other in the same series. The levers cl and e represent the two other series of levers, the same being mounted upon the shafts f and g, respectively, and coupled together and to the levers a by the rods h and k, respectively. The hooked jacks land m are respectively coupled to or made to lay hold of the pins Z and 'm, formed upon or attached to the arms cl and d of the lever d, and are made to eX- tend horizontally to be in proXimitywit-h the draw and push bars n and nf to or from which they are made to lay hold or to be clear of by means of the peg-lag or pattern-surface 0 on the pattern-cylinder 1), operating same in a well-known manner through the lever rand the needle or lifting-rod s. The draw and push bars at n and n n are connected or joined together, as shown in broken lines by Figs. 1 and 3, so that they may be simultaneously reciprocated by the rods 6 and 25', by which they are coupled to the oscillatory lever a, which receives its oscillatory motion through the rod 1; from any suitable motor, such as a crank attached to or formed on a rotary shaft driven by any prime motor.

Now when the lever d has been moved by one or other of its jacks Z or m into the position shown by Fig. 1 its arm (1 will have moved the lever e into the position for the center of its pin c, and that of the pin a on the lever a to be in line with the center of its shaft g, in which position (being also the outward extremity of its movement) this said lever a will be locked or rigidly held by reason of these several centers being in linewith each other, while when the lever 01 has been moved into the position shown by Fig. 3 its arm (1 will have moved the lever e by means of the rod it into the position for the center I h, the lever (Z, having arms d, (P, and (1 the of its pin it and that of the pin 7L2 on the lever-arm d to be in line With the center of the shaft f, in which position said lever e, and consequently also the lever a, (which has now reached the other or inward extremity of its 1nove1nent,) will be locked or rigidly held from moving in any direction until the said lever d is again moved by its motor.

The lever a, the rod is, the lever e, the rod hooked jacks Z and m, the bars n and n, the rods 25 and t, and the lever 14, in combination, all these several parts being mounted, constructed, and arranged to operate substantially as specified.
