It will also be clear that if the auxiliaryindicators 29 be so arranged in chain 31 as to alternately raise and lower lever 26 which is fast to lever 22 and the other end to frame 6. The auxiliar pattern indicators 29 are mounted on the bars of the auxiliarypattern chain 31, carried b barrel 32 on shaft 5 2, and barrel 32 is connected with astar-wheel 33, which is engaged by a pin 34 on arm 35, projecting from hub 36, which is mounted on sleeve 8, and hub 36 is connected to sleeve 8 by a key 37, which projects into keyway 13 IO in said sleeve, so that hub 36 is, like hub 11, free to move lengthwise of sleeve 8, but turns with it.

The other arm of lever 43 is pivotally conzo nected to the lower end of a link 45, which is pivotally connected at its upper end to a lever 46, fulcrumed upon a bar 47, which is also the fulcrum of the levers (not shown) for operating the box-shifting mechanism. Lever 2 5 46 is acted upon by the ends of certain of the bars of the main box-pattern indicator-chain 48, carried by the barrel 49, which is connected with star-wheel 16 by sleeve 50. the loom, and this condition is required par- 5 Lever 46 is moved in one direction by the ticularly when twofaced goods are being be alternately moved into operative position 75 of two of. the bars of chain 48 will be alternately placed in operative position and those two bars of thechain will suffice for any number of successive picks of the loom when weav- 8o ing pick-and-pick.

When the pattern being woven calls for the repeated alternation of more than two threadsthe indicators 29 are so arranged in 85 in operative position each for two successive picks of the loom, so that chain 48 will be moved forward two steps in succession and backward two steps in succession.

\Vhat we claim as our invention is 1. In a pattern mechanism for looms provided with 'a star-wheel and pin-wheel actu- 1 [o long as lever 46 is held in its lowermost position arm 35 is held in its inoperative position, as shown in Fig. 1, and chain 31 is held stationary.

On sleeve 8 is loosely mounted a hub 54,

from which projects an arm 55, which carries a pin 56, and hub 54 is integral with a gear 57, which engages a gear 58, fast on shaft 3,

w table in the opposite direction, and a free 11 5 5o arm 14 turn in the opposite direction.

ative position, to rotate said main-pattern 120 to rotate said main-pattern shaft in the opposite direction, and said main-pattern cylindershaft stationary when neither of the two pins 1 25 is in operative position and the star-wheel is in the free space between the two pins, substantially as shown and described.

2. In a pattern mechanism for looms provided with a star-wheel and pin-wheel actu- 1 o ating means, a horizontal pin-wheel shaft, a longitudinally-movable pin-wheel thereon rotatable in one direction, and a second longitudinally-movable pin wheel thereon rotapositions to its other position throws one arm 14 or 55 into operative position and the other arm out of operative position.

It will now be clear that so long as lever 26 is held in its uppermost position by auxiliary chain 48 will be moved forward in one direction step by step and arm 55 will occupy its inoperative position, and that so long as there are no auxiliary indicators 29 under lever 26 and the latter occupies its lowermost positable-in the opposite direction, a main-pattern cylindershaft parallel with said pinwheel shaft, a star-wheel fast thereon, operated by one pin-wheel when in operative position, to rotate said main-pattern shaft in one direction, and operated by the other pinwheel when in operative position, to rotate said main-pattern shaft in the opposite direction, substantially as shown and described.

3. In the pattern mechanism of a loom, a main-pattern surface,and means to move said pattern-surface either forward or backward, an auxiliary-pattern surface, means under the control of the main-pattern surface, in either its forward or backward movement, to move said auxiliary surface, or leave it at rest, and means under the control of said auxiliary surface, to move said main surface either forward or backward, substantially as shown and described.

4. In the pattern mechanism of a loom, having a star-wheel and pinwheel actuating mechanism, the combination with the starwheel of the main-pattern surface cylinder, of two hubs rotating in opposite directions, and each carrying an engaging pin, and means under the control of an auxiliary-pattern surface to move said hubs longitudinally, to disengage one and engage the other of the two pins with the said star wheel, whereby the patternsurface may be moved forward or backward, as one or the other of the pins may be in engagement with the said star wheel, substantially as shown and described.

5. In the pattern mechanism of a loom, having a star-wheel and pin-wheel actuating mechanism for the main and auxiliary pattern indicating mechanism, a pin-wheel shaft carrying a pin-wheel hub movable longitudinally, to move the main-pattern chain starwheel in one direction, and a second hub movable longitudinally, to move said starwheel in the opposite direction, and an endwise-movable rod carrying a yoke engaged with one of said hubs, and a second yoke engaged with said second hub, and intermediate connections between said endwise-movable rod and said auxiliary-pattern mechanism, to place either of said hubs in operative position to move said main-pattern star-wheel in either direction, substantially as shown and described.

6. In a loom having a star-wheel and pinwheel actuating mechanism, a main and auxiliary pattern indicating mechanism, a pinwheel shaft for carrying a pin-wheel hub movable longitudinally,to move the main-patternchain star-wheel in one direction, and a second hub movable longitudinally, to move said star-wheel in the opposite direction, an endwise-movable rod carrying a yoke engaged with one of said hubs, and a second yoke engaged with said second hub, and intermediate connections between said endwise-movable rod and said auxiliary-pattern mechanism to place either of said hubs in operative position to move said main-pattern star-wheel in either direction, and a third hub on said pin-wheel shaft, movable longitudinally, to move the multiplier-pattern star-wheel, a second endwise-movalo'le rod carrying a third yoke engaged with the third hub, and intermediate connections between said endwise-movable rod and said main-pattern mechanism, to place said third hub into or out of operative position with said multiplier starwheel, to move or leave it at rest, substantially as shown and described.

7. In a loom, the combination of a mainbox pattern-indicator chain for operating the box-shifting mechanism, means for actuating said main chain in one direction, separate means for actuating said main chain in the opposite direction, automatic mechanism for controlling both of said actuating means for effecting an automatic reverse of the main chain, an auxiliary-pattern indicator-chain, and an operative connection between the main-box chain and the auxiliary chain, said operative connection being controllable from an element of the main chain and comprising means for being thrown in and out of operative relation to the auxiliary chain for putting the motion of the latter in and out of play.
