Abstract
Abstract Apparatus for the transport of shuttles in looms and the simultaneous picking of weft threads by means of an endless chain conveyor carrying the shuttles and traversing a fixed guide means. A covering belt covers the parts of the chain traversing the space of the weaving process. A disconnectable means is provided on each shuttle for the joining of the shuttle with the respective carrier links.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
135 words
In an apparatus for the transport of shuttles in looms with simultaneous picking of weft threads by means of an endless chain carrying the shuttles and traversing a fixed guide means, the improvement which comprises an endless chain formed by alternating joined carrier links carrying the shuttles and connecting links, means to drive the chain to cause it to travel through the guide means, a covering belt covering the parts of the chain, traversing the space of the weaving process, each of the shuttles being adapted for travelling along the covering belt by means of a vertical roller journalled in the carrier link opposite a recess of the shuttle and another roller disposed in the shuttle, and a disconnectable means provided on each shuttle for the joining of the shuttle with the respective carrier links.

Claim 3
Dependent Claim
69 words
Apparatus for the transport of shuttles as defined in claim 1, wherein the disconnectable means comprise a shiftable conveyor accommodated in the carrier link and projecting by its inclined surface into an opening of the shuttle, the shuttle being provided with a recess in its lower part meshing with a starting guide disposed in the space of the weaving process and having its entering ends projecting out of it.
Claim 4
Dependent Claim
33 words
Apparatus for the transport of shuttles as defined in claim 1, wherein the shiftable conveyor is arranged in the direction of the carrier link behind the vertical roller disposed on the carrier link.
Claim 5
Dependent Claim
27 words
Apparatus for the transport of shuttles as defined in claim 1, comprising a resilient safety member fixed to the carrier link for selectively securing the shiftable conveyor.
Claim 6
Dependent Claim
31 words
Apparatus for the transport of shuttles as defined in claim 1, wherein the vertical roller is vertically adjustable in the carrier link, in accordance with the entrance on the covering belt.
Claim 7
Dependent Claim
57 words
Apparatus for the transport of shuttles as defined in claim 5, wherein the vertical roller is disposed in a rocking cradle of the carrier link supporting the shuttle, said cradle being provided with a pressur roll pressed against the bottom of the guide means by a pressure spring, said cradle being further provided with a thrust nose.
Claim 8
Dependent Claim
40 words
Apparatus for the transport of shuttles as defined in claim 6, wherein one of the shuttle and the carrier link is provided with a security member for their interconnection in the guide path outside the space of the weaving process.
Claim 9
Dependent Claim
56 words
Apparatus for the transport of shuttles as defined in claim 7, wherein in advance of the entrance into the space of the weaving process there is provided a lowered bottom in the bottom of the guide path for the pressure roller on the cradle, in order to let down the vertical roller in the carrier link.
Claim 10
Dependent Claim
67 words
Apparatus for the transport of shuttles as defined in claim 1, wherein for the connection of the carrier link with the shuttle there is provided a tunnel at the exit of the space of the weaving process, the height of said tunnel decreasing in the direction of the movement of the endless chain, while the lower part of the tunnel is formed by the said guide means.
Claim 11
Dependent Claim
42 words
Apparatus for the transport of shuttles as defined in claim 1, wherein the carrier links and the guide links are connected by means of connecting pins on which a horizontal roller is seated to roll in the recess of the guide means.
Claim 12
Dependent Claim
90 words
Apparatus for the transport of shuttles as defined in claim 1, wherein the guide means is generally of elliptical shape with spaced parallel straight portions and two arched parts at the ends of the straight portions, and comprising a fixing mechanism arranged in the arched parts of the guiding means, said fixing mechanism comprising swingable securing flaps radially disposed around the hub of the chain wheel and provided with control rollers, adjustable stops and adjustable springs, and a fixedly mounted half-circular bridge at the inner side of the guide means.
