专利汇可以提供Bale forming and tying mechanism专利检索，专利查询，专利分析的服务。并且A baler having a baling chamber and a compacting piston for forming bales in end to end relation through the chamber. A supply source of wire is provided and a wire carrying needle is operative by power driven means to move up and down at intervals through the baling chamber. Wire tying means are associated with the needle for tying the wire after a bale has been completed. The needle is of a length and has a necessary movement above the baling chamber to leave a loop of wire above the chamber of a length equivalent to substantially the length of a bale in order that as the bale is formed, the wire along the top of the bale is fed from the loop. Wire does not therefore have to be pulled between tightly compressed bale portions. This function is accomplished by a latch and reset assembly operated by tension from the wire after the loop has been depleted.，下面是Bale forming and tying mechanism专利的具体信息内容。

权利要求

1. A bale forming and tying mechanism comprising a. a frame, b. a baling chamber on said frame with a material receiving entrance and a reciprocating piston for compacting bales in end to end relation and forcing them through the baling chamber, c. a supply source of bale tying wire, d. a wire carrying needle on said frame, e. power driven means on said frame causing the needle to move up and down at intervals through the baling chamber, f. wire tying means on said frame, g. said needle being arranged to carry wire upwardly for placing it in said wire tying means and having an upward movement above said baling chamber sufficient to leave a loop of wire above the baling chamber of a total length equivalent to substantially the length of a bale, h. and control means for controlling the operation of said power driven means for the needle, i. said control means comprising a movable linkage engageable by the wire and releasable by tightening movement of the wire after the loop is depleted.

2. The bale forming and tying mechanism of claim 1 wherein said power driven means includes a rotatable disc assembly, a lever arm on said disc assembly connected to said needle for causing up and down movement of the needle as said disc assembly is rotated, and a stop projection on said disc assembly; said movable linkage including a movable latch member, said control means also including reset meAns arranged for engagement with said latch member, said reset means controlling operation of said latch member and being operated by linear movement of said bale.

3. The bale forming and tying mechanism of claim 1 wherein said power driven means includes a rotatable disc assembly, a lever arm on said disc assembly connected to said needle for causing up and down movement of the needle as said disc assembly is rotated, and a stop projection on said disc assembly; said movable linkage including a movable latch member, said control means also including a reset arm connected to said movable linkage, a metering wheel on said baler having a portion thereof projecting into the baling chamber for rotation by linear movement of a bale in such chamber, and a drive connection between said metering wheel and said reset arm whereby upon rotation of the metering wheel by the movement of a bale the reset arm is driven to a position allowing release of said movable linkage.

4. The bale forming and tying mechanism of claim 1 wherein said power driven means includes a rotatable disc assembly, a lever arm on said disc connected to said needle for causing up and down movement of the needle as said disc assembly is rotated, and a stop projection on said disc assembly; said movable linkage including a movable latch member, guide means operably connected to said movable latch member, said control means also including reset means arranged for engagement with said latch member, said reset means controlling operation of said latch member and being operated by linear movement of said bale, said guide means being arranged to be engaged by the wire extending from the loop to one side of the bale and being movably mounted and arranged to release said latch member from said reset means upon tension being applied to the wire.

5. The bale forming and tying mechanism of claim 1 wherein said control means also includes reset means controlling operation of said movable linkage and operated by linear movement of said bale and by said power driven means.

6. The bale forming and tying mechanism of claim 1 wherein said control means also includes a reset arm connected to said movable linkage, said reset arm being arranged to be driven to a position allowing release of said movable linkage by linear movement of said bale.
