Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
A device for inserting pre-wound coils into grooves of stators comprising: (a) a stripper member mounted for movement through a stator, said stripper member including a plurality of equally spaced radially extending projections positioned about periphery of the stripper member, each said projection being positioned across from a stator groove; (b) lamella members located in planes passing between the projections of the said stripper member and extending in a direction parallel to the direction of relative movement between the stripper member and the stator; (c) a locating member, which is stationary relative to the movement of the stripper member through said stator, the peripheral cross-sectional configuration of part of which corresponds to that of the said stripper member, said locating member being adapted to receive the ends of the lamella members, and (d) a locking ring member adapted to cooperate with said locating member to lock ends of lamella members in position on the locating member; characterized in that the ends of each lamella member is adapted to be locked into position on said locating member by means of said locking ring member.
Claim 2
Independent Claim
183 words
A device for inserting pre-wound coils into grooves of stators comprising: (a) a stripper member mounted for movement through a stator, said stripper member including a plurality of equally spaced radially extending projections positioned about periphery of the stripper member, each said projection being positioned across from a stator groove; (b) lamella members located in planes passing between the projections of the said stripper member and extending in a direction parallel to the direction of relative movement between the stripper member and the stator; (c) a locating member, which is stationary relative to the movement of the stripper member through said stator, the peripheral cross-sectional configuration of part of which corresponds to that of the said stripper member, said locating member being adapted to receive the ends of the lamella members, and (d) a locking ring member adapted to cooperate with said locating member to lock ends of lamella members in position on the locating member; characterized in that the ends of each lamella member is adapted to be locked into position on said locating member by means of said locking ring member.
Claim 3
Dependent Claim
35 words
A device according to claim 1 wherein a lamella on at least one side of each said radially extending projection having a pre-wound coil associated therewith is fixed to the stripper member for movement therewith.
Claim 4
Dependent Claim
46 words
A device according to claim 1 wherein the opposite edges of each lamella face opposing a ridge of the stator between adjacent stator grooves is provided with a projecting ridge or guide such that the lamella covers the edges of the entrance into the stator groove.
Claim 5
Dependent Claim
25 words
A device according to claim 1 wherein the ends of each lamella are shaped to fit under a peripheral ridge on said locking ring member.
Claim 6
Dependent Claim
158 words
A device according to claim 1, wherein the stripper member and the locating member are provided with axially extending slots on the peripheral edges thereof between the said radially extending projections, said slots extending through both the stripper member and the locating member in a direction parallel to the direction of movement of the stripper member relative to the stator and the locating member, wherein a portion of the cross-section of each lamella member may be located in said slots, wherein alternate lamella members are slidable in the slots on the locating member but are fixed to the stripper member in respective alternate slots thereof for movement therewith through the stator and the locating member, and wherein the remainder of the lamella members are slidable in the slots in both the stripper member and the locating member in a direction parallel to the direction of movement of the stripper member relative to the stator and the locating member.
