LOOM.

SPECIFICATION forming part of Letters Patent No. 561,933, dated June 9, 1896.

Application filed November 4, 1895. Serial No. 567,902. (No model.)

To [4Z3 whom it ntoty concern:

Be it known that we, GEORGE EDWARD BEAUMONT, powerloom tuner, and JOHN POL- LOOK FAULDS, engineer, British subjects, and residents of Dunedin, in the Colony of New Zealand, have invented certain new and useful Improvements in Looms, of which the following is a specification.

Our invention includes the special. features of construction and arrangement of parts hereinafter particularly described, and pointed out in the claims.

In order that our invention may be most easily understood by one skilled in the art to which it appertains, we have illustrated the same upon the accompanying drawings, to

which we shall refer while giving a detailed description.

Similar letters of reference indicate similar parts throughout the views.

Figure 1 is a front view of our apparatus and showing such parts of a loom as are necessary for purposes of description. Fig. 2 is a side view of the same. Fig. 3 is a side section of the harness and showing one of the vibrators raised by one of the pegs. Fig. 4 is a perspective view of one of the lags with its pegs on a larger scale. Fig. 5 is aview of the slotted bearing of the cylinder on a larger scale. Fig. 6 is a side view of apparatus for steadying the cylinder. Fig. 7 is a side view of part of Fig. 3. Fig. 8 is a plan of the clutch. Fig. 9 is an elevation of the same.

The lags a are shaped, as shown in Fig. 4, to lit the ordinary cylinder Z2, as shown in Fig. 3, and are made of hard wood by preference. These lags are joined together by links a, which are readily opened and taken apart when more or less lags are required, and are provided with holes a which are spaced apart to correspond with the position of the vibrators c. Hard-wood pegs a lit tightly into these holes a, and, passing through the lags, rest upon the body of cylinder 1). In place of the usual metal friction-block upon vibrators c we use a block made of hard wood 0 for receiving the thrust of pegs a Said pegs a? may be readily removed by means of a pair of pliers from one hole to another, and, if desired, without taking the lags off the machine. lVhen joined together, these lags constitute a pattern or box-pattern chain and replace the present expensive, heavy, and intricate pattern-chain. A roller a of wood by preference, is passed through the lower end of the patternchain and is carried upon suitable brackets of for guiding the lags toward the cylinder 7). Brackets a are lined to the usual supports a and may be adjusted by means of holes a to suit varying lengths of harness. Light rods to, fixed into bar a and actuated by spiral. spring a press upon the lags as they pass over the cylinder and retain the same in position. 7

Cylinder b is revolved by star-pointer (t, which is keyed upon the extension of the journal of said cylinder, and by kicker d, which is keyed to shaft (2 Motion is imparted to shaft (1 from shaft 6 through bevel-wheels c or 6 intermediate bevel-Wheel c and bevelwheels e and 6 Wheels 6 and e are keyed to shaft 6, which revolves in its bracket 6 and wheel 0 is keyed to shaft (1 and has a step-bearing in bracket 6". Bevel-wheels c and (2 run loosely upon shaft 6, and either may be brought into operation by means of clutch e which is connected to shaft 6 by a feather, but is free to be raised or lowered by lever e working on pillar 6", link e, and hand-levers Clutch 0 is shown separately in Fig. 8, where m are lugs which engage with similar lugs m on bevel-wheels c and 6 The fork of lever e works within groove m Shaft e is revolved in the usual manner by wheels 6 c and e and clutch e Ac- 8 5 cording as clutch e is operated to engage with wheel 6 or 6 so wheel 6 will revolve one way or the other and with it shaft d In this manner the pattern-chain is made to reverse at will.

Oylindersf and f are revolved by bevelwheels f and f and f and f respectivelygin the usual manner, and upon the extensions of anlef of cylinder ,1 are keyed cams f having a flatside, as shown by dotted line in Fig. 9 5 Above these cams are provided levers j, which revolve around their fulcrums f and have near their central part friction-rollers f Upon their outer ends these levers f receive a shaft f and to this said shaft are suspended links f. The axle Z) of cylinder Z) passes through and revolves within the with it clutch c lower ends of said links 7 and also passes through its slotted bearing f. (Shown on large scale in Fig. 5.) Bearing f is carried within the main frame f of the machine and held byset-screw f in the usual manner.

The manner in which our apparatus operates is as follows: Shaft 6, supported on its bracket g, which is attached to main framing 71;, runs continuously in one direction carrying By operating lever 6 said clutch may be made to engage with. bevelwheel 6' or e to revolve shaft (1 in eithendt rection. Bevel-Wheels e, 8 e c, 6 f f f, and f have all the same number of teeth, so that shafts e and (Z and cylinders f and f make the same number of revolutions in any given time and simultaneously. It therefore will be seen that cam f and kicker (1 make their revolutions simultaneously, and they are so placed relatively to each other that cam f permits lever f to fall while kicker (6 revolves star-pointer cl the distance of one tooth. By the fall of said lever f the cylinder band vibrator 0 also fall; but the vibrator is retained in the usual manner upon its levelingbar n, Fig. 2, and cylinder 7) continues to fall until peg a is clear of its vibrator. Kicker d then advances cylinder 1) the distance of one toot-h of star-pointer d and brings the next lag, with its pegs, into position. Here the said cylinder b is held steady by its indented roller j, friction-wheelj, and spring j The action of this indented roller will be obvious from Fig. (i, where carrier jiand its friction-wheel j are forced against roller 7' by spring 7' \Vhile in this lower position Wheel 0' will have engaged with lower cylinder f and brought connector c back into its first position. A fresh lag being now in position and cam f continuing to revolve, lever f will be raised, and with it cylinder Z) and such vibrators as are found above the pegs, until wheels 0 engage with upper cylinder f to operate connectors 0 In this manner the operations are repeated and continued and the heddles of the loom operated as required to work the pattern in hand.

confine ourselves to the exact details herein before described, as these may be varied in several ways without departing from the principle of our invention.

WVe are aware that lags and pegs have been used upon other machinery, and we do not claim the use of these, broadly but,

Having now described our invention, what We claim as new, and desire to secure by Let ters Patent, is

1. In combination in a 100111, the upper and lewer cylinders f, f, the vibrator having the crank-gears with connectors for operating the shed-"forming mechanism, the pattern-cylinder with its chain, the cams f on the shaft of one of the cylinders, the levers f and depending links f operated thereby, said links having the pattern-cylinder at their lower ends, the star-wheel on the pattern-cylinder shaft, the upright shaft d the kicker (1 thereon for operating the star-wheel of the patterncylinder when the same is lowered and means as described.

2. In combination the cylinders f, f, the vibrators with their crank-gears and connectors for operating the shed-forming mechanism, the pattern-cylinder with its chain for operat-in g the vibrators, means for raising and lowerin g the pattern-cylinder comprising the cams f on the shaft of the upper cylinder. the horizontal levers f the links f dependfrom the free ends thereof and carrying the said pattern-cylinder at their lower ends. the star-wheel on the pattern-cylinder, the kicker for operating the same, the upright shaft d carrying the kicker, the upright shaft 6, the gearing between the same and the cylinder-shafts, and means for operating the said shafts, substantially as described.

In witness whereof we have hereunto set our hands in the presence of two witnesses.

GEORGE EDWARD BEAUMONT. JOHN POLLOCK FAULDS.
