专利汇可以提供Electromagnetically operated stapler专利检索，专利查询，专利分析的服务。并且The operating winding of an electromagnetically operated stapler is in the period of time during the working stroke connected with a capacitor the discharge current of which energizes said winding with a strong current surge whereby a high impact power for driving staples into a work piece is achieved. During the charging period the capacitor is separated from said winding and joined to an alternating current source.，下面是Electromagnetically operated stapler专利的具体信息内容。
1. In an electromagnetically operated tool adapted to be energized by an alternating current potential source and controlled to provide a single power stroke comprising a housing, winding means disposed in the housing, magnetically actuating means movably arranged adjacent the winding means, a manually actuated switch means carried by the housing and adapted to be joined to said winding means for initiation a working stroke of the tool, a capacitor means with one pole connected to said switch means and with the other pole connected to said alternating current potential source, and means controlled by actuation of said switch means for energizing said winding means by the discharge current of said capacitor means and separating said capacitor means from said alternating current potential source.
2. The tool as claimed in claim 1 wherein said capacitor means is arranged exterior to the housing of the tool.
3. The tool as claimed in claim 2 wherein said capacitor means together with a quenching and an Ohmic resistance are mounted on a main plug.
4. The tool as claimed in claim 3 wherein said capacitor means and resistance means are disposed within the housing of said main plug.
5. The tool as set forth in claim 1 wherein the capacitor means comprise an electrolytic condenser.
6. The tool as set forth in claim 1 wherein the magnetical actuating means and said winding means are mounted within a frame enclosed by a portion of the tool housing which frame is adapted to relieve the housing from the mechanical forces of the magnetical actuating means.
7. The tool according to claim 6 wherein the winding means is composed of aluminium.
8. The tool according to claim 7 wherein said winding means is wound of an oxidized aluminium foil.
9. The tool according to claim 6 wherein the winding means is mounted between two crosspieces inserted in said frame, which crosspieces form a guide for the armature and an extension pin of said armature, which extension pin is adjacent the magnetically actuating means.
10. The tool according to claim 9 wherein on the upper crosspiece a cover plate is secured absorbing the recoil action of the armature.
11. The tool according to claim 9 wherein said pin constituting an extension of the armature and abutting a lever of the magnetic actuating means is made of antimagnetic material.
12. The tool according to claim 11 wherein the pin is made of a niCkel-manganese-steel alloy.
13. The tool according to claim 11 wherein the lower end portion of the pin abutting the lever is provided with a hardened insert.
14. The tool according to claim 1 wherein the frame is made of ferromagnetic material, particularly sheet iron.
