SPECIFICATION forming part of Letters Patent N o. 729,880,'dated June 2, 1903. Application filed October 24, 1902. SerialNo.128,521. (No model.)

To all whom, it may concern,-

Be it known that I, WILLIAM J. LUTTON, a citizen of the United States, and a resident of Paterson, in the countyof Passaic and State of New Jersey, have invented a new and useful Improvementin Pattern Mechanism for Looms, of which the following is a specification.

My invention relates to an improvement in looms, and has more particularly for its object to provide a new pattern-chain whereby the heddles may be operatedto produce a great varietyof weaves with a pattern-chain ofvery few bars, thus materially reducing the cost of the pattern chain and also the weight thereof.

A still further object is to providea new pattern-chain in which rocking bars are pro-' vided with mutilated spools, so that when the bars are turned in one direction the spools may be used'to operate the heddle's and when turned in the other direction will fail to operate the heddles.

A further object is to provide a loom in which an indicator controlled by a box-chain is provided for turning the bars of the pattern-chain so as to call in the diiferent weaves.

A practical embodiment of my invention is represented in the accompanying drawings,

in which-- Figure 1 is a transverse section through a:

loom, certain of the parts being broken away to more clearly show the operationof my new Fig. 3 is a detail sectional indicator-bar.

idler-shaft, its sprocket-wheels, and guidingwheel. Fig. 6 is a transverse vertical section through the pattern chain and its support, showing the 1 nutilated spools in different positions and also showing sfeveral full spools. Fig. 7 is a top plan viewof a portion of the pattern-chain and its supports, showing the showing the double-spur tripper operated by. Fig. 10 is.

Fig. 12 is a similar view showing one of the full spools. plane, of the support at one side of the pattern-chain; and Fig. 14 is a similar view of the support at the other side of the patternchain.

The loom-frame herein represented is denoted by 1. Two heddles 2 and 3, with their operating mechanisms, are'also represented.

The pattern-chain is composed of a series of angular bars/4, connected at their opposite ends by two series of links 5 and 6. In the present instance I have shown these bars 4 as being square in cross-section. The space between the two series of side links 5 and 6 upon each of the bars 4 is filled by aplurality of collars 7 of equal'lengths. Some of these collars 7 are provided with full spools 8,. which will always raise one of the heddle-controlling bars when brought" in contact therewith. Others of the collars 7 are provided with mutilated spools 9.

The collars 7, which have the mutilated spools 9 thereon, are keyed to turn with the bar 4, preferably by providing the said sleeves with angular sockets corresponding to the shape in cross-section of the said-bar,

On any one particular barsuch, for in stance, as the upper bar shown in Fig. 6,

which is the same bar as the lower bar shown in Fig. 7two of the mutilated spools are placed upon the bar opposite to two others of the mutilated spools. This bar is also provided with a completespool 8. It willthus be seen that when this bar is turned to one position one set of two ofthemutilated-spools 9 will be caused to. engage the heddle-con trolling bars, and when the said baris turned into another position, a half revolution from the first-named position, the other two muti- Fig. 11 is a similar view showing Fig. 13 is a detail view, in top lated spools 9 will be brought into position to raise their corresponding heddle-controlling bars. Therefore whenever this particular bar is brought into position to operate the heddles, the full spool 8 will always operate its heddle-controlling bar and two of the mutilated spools 9 will operate their corresponding heddle-controlling bars.

Each of the cross-bars 4 of the chain is provided near one end with a single-spur tripper, fitted to be engaged by the indicatorcontrolled roller when in its lower position. This single-spur tripper is constructed by providing a collar 10 of the same length as the collars 7 and providing the said collar 10 with a spur 11. This tripper is fixed to rock with the bar 4, preferably by providing the socket therethrough to correspond with the shape in cross-section of the said bar.

Each of the bars 4 is provided at one end, preferably the end adjacent to the series of side links (3, with a double-spur tripper fixed to rock with the said bar. This double-spur tripper is made, preferably, by providing a collar 12, having a socket therethrough corresponding to the shape in cross-section of the bar 4, which collar is provided with oppositely-extended spurs 13 and 14, arranged at right angles to the single spur 11 of the single-spur tripper. These double-spur trippers are fitted to be engaged by a controllingroller carried by the frame, which will be hereinafterdescribed.

The pattern-chain passes around an upper driving-shaft 15 and a lower idler-shaft 16, in engagement with the usual pairs of sprocketwheels 17 and 18, which engage the series of side links 5 and 6.

The series of side links 5 and 6 of the pattern-chain rest upon rigid guides 19 and 20, secured to the frame as they pass from the sprocket-wheels 17 to the sprocket-wheels 18. The said series of side links 5 and 6 are also supported for a part of the distance as they pass from the sprocket wheels 18 to the sprocketwheels 17 by guides 21 22, which are held in position by pairs of looped supporting-bars 24, which connect the guides 21 22 with the supports 19 and 20. The recesses through the side links are sufficiently large to permit the angular cross-bars 4 to freely rock therein.

The bars 4 are prevented from turning while passing around the driving-shaft 15 by means of a guiding-wheel 25,which is in alinement with the double-spur trippers 13 and 14. The mutilated spools 9 upon each bar as it passes beneath the heddle-controlling bar will therefore be held in its proper positions to raise the bars to pass idly beneath the same. The bars 4 are also held from turning while passing around the idler-shaft 16 by means of a similar guiding-wheel 26, also in alinement with the double-spur trippers 13 and 14.

The means which I employ for rocking the bars a half-revolution in one direction by two successive movements and a half-revolution back by two successive revolutions, when. so desired, is constructed and arranged as follows: A box-chain 27 is provided at suitable intervals with spools 28, which boX- chain passes around a sprocket-wheel 29 on the upper driving-shaft 15 of the pattern-chain.

A rock-bar 30, similar to the heddle controlled bars, is mounted in position to be engaged and raised by the spools 28 of the boxehain, the said rock-bar 30 being fitted to raise and lower an indicator-roller 31 out of and into the path of the single-spur trippers 11. This rock-bar 30 is connected to the roller 31 as follows: The roller 31 is carried by the lower end of a Vertically-reciprocating rod 32, the upper end of which is adjustably secured to one arm, 33, of a rocking lever pivoted to the frame at 34, the other arm, 35, of the said lever being connected to the free end of the rock-bar 30 through a link 36.

The vertically-reciprocating rod 32 passes through a horizontal rail 37 of the frame and is prevented from turning therein preferably by squaring the rod 32 where it passes through the rail 37, as shown at 38.

The double-spur-tripper-controlling roller 39 is mounted in the free end of an arm 40, supported by the rail 37, so that the said roller 39 is located in the path of the doublespur trippers.

Two fingers 41 42 are secured to the guide 21, the finger 41 being extended into the path of the single-spur tripper 11 and the finger 42 being extended into the path of the doublespur tripper 13 14.

An intermediate guide f finger 43 is arranged to hold the chain down against its support 19 while the bar is being turned by the preceding single-spur tripper because of its engagement with the finger 41.

The pattern-chain is placed in position around the shafts 15 and 16 with the singlespur trippers projecting outwardly from the chain. Then the bars of the chain are in this position,with the single-spur trippers projecting outwardly, the double-spur trippers will be located longitudinally of the chain and a certain series of mutilated spools will be in position to raise their corresponding heddle-controlling bars, while the other series of mutilated spools will be in position to pass freely under their corresponding heddlecontrolling bars, without operating the same. As the bars of the chain leave the sprocketwheels 18 on the shaft 16 the single-spur trippers 11 project outwardly.

If it is desired to turn a bar a half-revolution to turn certain of its mutilated spools out of position to engage their heddle-controlling bars and the other mutilated spools into position to engage their heddle-controlling bars, it is done as follows: One of the spools 28 upon the box-chain n7 is brought into engagement with the rock-bar 30 in time to lower the single-spur-trip1:)er-controlling roller 31 into the path of the single-spur tripper carried by the bar which itis intended to turn. As the pattern-chain is moved along by the driving-shaft 15 and its sprocketwheels 17 the roller will turn the bar 4 a quarter-revolution, thus bringing the doublespur tripper 13 14: into a position at right angles to the chain. As the chain continues to move forwardly the controlling-roller 39 will engage the spur of the double-spur tripper which projects outwardly and turn the bar at another qualter-revolution. This will bring the mutilated spools which were projecting outwardly into a position projecting inwardly and also bring the mutilated spools which were projecting inwardly into a position projecting outwardly from the chain. The bar passes around the driving-shaft 15 beneath the heddle-controlling bars in this position. When the box-chain 27 fails to lower the controlling-roller 31 into the path of the single-spur trippers 11, the bars will travel along up to the heddle-controllin g bars without being shifted, for thereason that the controlling-roller 39 will pass along the outer sides of the double-spur trippers 13 14 with out turning the same, as the said double? spur trippers will be arranged longitudinally of the chain. The bars are always returned to their normal position before they reach the shaft 16 by the following mechanism: As the pattern -chain leaves the shaft 15 the finger 41 will engage any imvardly-projected single-sp ur trippers 11, and thus turn the bar 4 backwardly a quarter-revolution. \Vhile this is being done the pressure of the guidefinger 43 holds the chain firmly down upon its support 19. Before the chain reaches the shaft 16 the finger 42 will engage any inwardly-projecting spur of the double-spur trippers 13 14, thus turning the bars a a quarter-revolution back to their normal position.

By the arrangement hereinabove described it will be seen that I am enabled to produce a great many changes in the weave with a very short chain, for the reason that the changes in the pattern can be controlled from the box-chain so as to produce a great number of combinations in the mutilated spools.

In the device herein shown the loom will be weaving the ground-weavewhen the sin glespur trippers are projecting outwardly and the cross-stripe weave may be called in at any time from the box-chain by lowering the roller 31 into position to engage one of the outwardly-projected single-spur trippers for bringing the double-spur tripper into position to be engaged by the roller 39 for completin g a half-revoluti on of the pattern-chain bar, as has been heretofore clearly described.
