Abstract
Abstract A dobby machine has retaining hooks which are guided for rectilinear reciprocal movement and are connected by pivoted links to opposite ends of a rocking member connected by linkage with a heald or dobby shaft. Each of two two-part levers comprises two lever parts which are pivoted about a common pivot and are movable relative to one another. One lever part has a hook portion and constitutes a holding hook engageable with the respective retaining hook. The other lever part carries a reading needle for sensing a pattern controlling the machine and has a portion engageable with the holding hook lever part to control whether or not the holding hook is in position to engage the respective retaining hook. When the hooks are engaged with one another, a locking member releasably engages the holding hook to hold it in engaged position. However, the holding hook is movable longitudinally relative to its pivot to free it from the locking member.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
130 words
In a dobby machine having a dobby shaft and means for feeding a perforated pattern, the combination of a reciprocable retaining hook, linkage means connecting said retaining hook with said dobby shaft, a two-part actuating lever comprising first and second lever parts pivotal about a common pivot and movable relative to one another, said second lever part having hook means and constituting a holding hook selectively engageable with and disengageable from said retaining hook, said fist lever part having sensing means for sensing a pattern fed by said feed means and means engageable with said second lever part to move said holding hook in position to engage said retaining hook and means engageable with said second lever part to lock said holding hook stationary in engagement with said retaining hook.
Claim 2
Dependent Claim
130 words
In a dobby machine having a dobby shaft and means for feeding a perforated pattern, the combination of a reciprocable retaining hook, linkage means connecting said retaining hook with said dobby shaft, a two-part actuating lever comprising first and second lever parts pivotal about a common pivot and movable relative to one another, said second lever part having hook means and constituting a holding hook selectively engageable with and disengageable from said retaining hook, said fist lever part having sensing means for sensing a pattern fed by said feed means and means engageable with said second lever part to move said holding hook in position to engage said retaining hook and means engageable with said second lever part to lock said holding hook stationary in engagement with said retaining hook.
Claim 3
Dependent Claim
49 words
A combination according to claim 1, in which said second lever part is pivoted at one end and has said holding hook at the opposite end, and in which said locking means comprises a movable locking member engageable with said second lever part at the holding hook end thereof.
Claim 4
Dependent Claim
29 words
A combination according to claim 2, in which said second lever part is longitudinally movable relative to said pivot to disengage said second lever part from said locking member.
Claim 5
Dependent Claim
30 words
A combination according to claim 1, in which said locking means is engageable with said second lever part to hold said holding hook out of engagement with said retaining hook.
Claim 6
Dependent Claim
44 words
A combination according to claim 1, in which said first lever part is pivoted at one end and in which said sensing means comprises a pattern reading needle engageable with said pattern and connected directly with the other end of said first lever part.
Claim 7
Dependent Claim
144 words
In a dobby machine having a frame, a dobby shaft and means for feeding a pattern, the combination of a reciprocable retaining hook, linkage means connecting said retaining hook with said dobby shaft, a holding hook pivotally movable about a pivot on said frame between an engaged position in which said holding hook is in engagement with said retaining hook and a disengaged position in which said holding hook is out of engagement with said retaining hook, means for reading a pattern fed by said feeding means, means connecting said pattern reading means with said holding hook to move said holding hook between said disengaged position and said engaged position in accordance with said pattern, and means for locking said holding hook in engaged position, said holding hook being movable longitudinally relative to its pivot to disengage said holding hook from said locking means.
Claim 8
Dependent Claim
144 words
In a dobby machine having a frame, a dobby shaft and means for feeding a pattern, the combination of a reciprocable retaining hook, linkage means connecting said retaining hook with said dobby shaft, a holding hook pivotally movable about a pivot on said frame between an engaged position in which said holding hook is in engagement with said retaining hook and a disengaged position in which said holding hook is out of engagement with said retaining hook, means for reading a pattern fed by said feeding means, means connecting said pattern reading means with said holding hook to move said holding hook between said disengaged position and said engaged position in accordance with said pattern, and means for locking said holding hook in engaged position, said holding hook being movable longitudinally relative to its pivot to disengage said holding hook from said locking means.
Claim 9
Dependent Claim
