Abstract
Abstract Apparatus for transporting yarn at high speeds by fluid from a delivery point to receiving stations including one or more delivery conduits receiving yarn from the delivery point, a yarn cutting mechanism for each delivery conduit, distribution conduits communicating with each delivery conduit, each of the distribution conduits being directed toward one of the receiving stations, a nozzle carried by each of the distribution conduits for creating a flow of compressed air in the distribution conduits and a control system for operating the yarn cutting mechanisms and selectively supplying compressed air to the nozzles to control the direction of yarn movement through the distribution conduits from each delivery conduit after actuation of the yarn cutting mechanism.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
102 words
Apparatus for transporting yarn at high speeds by fluid from a delivery point to a plurality of receiving stations comprising a delivery conduit having inlet means for receiving yarn from the delivery point and outlet means; yarn cutting means disposed in said delivery conduit; a plurality of distribution conduits communicating with said delivery conduit at said outlet means, each of said distribution conduits being directed toward one of the receiving stations; and nozzle means for creating a flow of fluid in said distribution conduits whereby yarn moving through said delivery conduit enters said distribution conduits under the control of said nozzle means.
Claim 2
Dependent Claim
102 words
Apparatus for transporting yarn at high speeds by fluid from a delivery point to a plurality of receiving stations comprising a delivery conduit having inlet means for receiving yarn from the delivery point and outlet means; yarn cutting means disposed in said delivery conduit; a plurality of distribution conduits communicating with said delivery conduit at said outlet means, each of said distribution conduits being directed toward one of the receiving stations; and nozzle means for creating a flow of fluid in said distribution conduits whereby yarn moving through said delivery conduit enters said distribution conduits under the control of said nozzle means.
Claim 3
Dependent Claim
24 words
Apparatus for transporting yarn as recited in claim 1 and further comprising control means for operating said yarn cutting means and said nozzle means.
Claim 4
Dependent Claim
58 words
Apparatus for transporting yarn as recited in claim 2 wherein said nozzle means includes a nozzle disposed in each of said distribution conduits and a source of compressed air, and said control means includes valve means controlling flow from said source to each of said nozzles to selectively create a flow of compressed air in said distribution conduits.
Claim 5
Dependent Claim
57 words
Apparatus for transporting yarn as recited in claim 3 wherein said control means includes means responsive to said yarn cutting means to operate said valve means to create a flow of compressed air in one of said distribution condUits other than the conduit through which the yarn was moving prior to operation of said yarn cutting means.
Claim 6
Dependent Claim
32 words
Apparatus for transporting yarn as recited in claim 2 wherein said outlet means includes a plurality of aligned outlet ports, each of said distribution conduits communicating with one of said outlet ports.
Claim 7
Dependent Claim
25 words
Apparatus for transporting yarn as recited in claim 5 wherein said delivery conduit is vertically disposed and said outlet ports are disposed in horizontal alignment.
Claim 8
Dependent Claim
112 words
Apparatus for transporting yarn as recited in claim 2 and further comprising a second delivery conduit having inlet means for receiving a second yarn from a delivery point and outlet means, yarn cutting means disposed in said second delivery conduit, a plurality of distribution conduit communicating with said second delivery conduit at said outlet means, each of said distribution conduits being directed toward one of the receiving stations, nozzle means for creating a flow of fluid in said distribution conduits communicating with said second delivery conduit, and a discharge conduit for each of the receiving stations, a distribution conduit from each of said delivery conduits communicating with each of said discharge conduits.
Claim 9
Dependent Claim
42 words
Apparatus for transporting yarn as recited in claim 7 wherein said control means includes a source of compressed air, valve means for controlling the supply of compressed air to said nozzle means and timing means controlling the operation of said valve means.
Claim 10
Dependent Claim
42 words
Apparatus for transporting yarn as recited in claim 2 wherein said control means includes a source of compressed air, valve means for controlling the supply of compressed air to said nozzle means and timing means controlling the operation of said valve means.
Claim 11
Dependent Claim
138 words
Apparatus for separately transporting n yarns at high speed by fluid from n delivery points to at least n + 1 receiving stations comprising n delivery conduits, each having inlet means for receiving yarn from the delivery points and outlet means; yarn cutting means disposed into each of said delivery conduits; n + 1 discharge conduits, each adapted to direct yarn toward one of the receiving stations; a plurality of n + 1 distribution conduits communicating with each of said delivery conduits at said outlet means, each of said distribution conduits communicating with each delivery conduit being directed toward one of said discharge conduits; and a nozzle disposed in each of said distribution conduits for creating a flow of fluid therein whereby yarns moving through said delivery conduits enter said distribution conduits under the control of said nozzles.
Claim 12
Dependent Claim
138 words
Apparatus for separately transporting n yarns at high speed by fluid from n delivery points to at least n + 1 receiving stations comprising n delivery conduits, each having inlet means for receiving yarn from the delivery points and outlet means; yarn cutting means disposed into each of said delivery conduits; n + 1 discharge conduits, each adapted to direct yarn toward one of the receiving stations; a plurality of n + 1 distribution conduits communicating with each of said delivery conduits at said outlet means, each of said distribution conduits communicating with each delivery conduit being directed toward one of said discharge conduits; and a nozzle disposed in each of said distribution conduits for creating a flow of fluid therein whereby yarns moving through said delivery conduits enter said distribution conduits under the control of said nozzles.
Claim 13
Dependent Claim
27 words
Apparatus for separately transporting yarns to receiving stations as recited in claim 10 and further comprising control means for operating said yarn cutting means and said nozzles.
