Abstract
The shuttle is formed with a nose member which overlaps the front edges of the housing while being disposed within the projected plane of the housing. The housing may also be compressed between the pin and nose member to press the mating surfaces of the housing and nose member together. Gaskets may also be used between the nose member and housing or between the pin and housing to effect a resilient connection.
Claims15
A gripper shuttle for picking weft yarns in a weaving machine comprising
- a shuttle body housing of tubular construction having a front end;
- a nose member at said front end of said housing and having inwardly and rearwardly facing inclined surfaces thereon engaging at least part of said front end of said housing;
- a spigot within said front end of said housing secured to said nose member;
- and
- means securing said spigot to said housing to press said surfaces of said housing and said nose member together under a longitudinally directed compressive force.
2 more elements
A gripper shuttle comprising
- a housing of synthetic plastics material having a front end;
- a nose member projecting from said front end of said housing having surfaces overlying at least part of a forward edge of said front end and being of a reduced transverse cross-section relative to the transverse cross-section of said housing;
- and
- means for securing said nose member to said housing to press said surfaces of said housing and said nose member together under a longitudinally directed compressive force.
1 more element
A gripper shuttle comprising
- a shuttle body housing of tubular construction and of a tough impact-resistant resilient plastics material, said housing having a front end and a pair of oppositely aligned bores therein;
- a metal nose member at said front end of said housing having inwardly and rearwardly facing inclined surfaces thereon engaging at least part of said front end of said housing;
- a spigot secured to said nose member and mounted within said housing, said spigot having a bore therein normally disposed nearer said surfaces of said nose member than said bores of said housing;
- and
- a pin passing through said bores of said housing and said spigot to connect said housing to said spigot while longitudinally compressing said housing between said pin and said nose member.
2 more elements
A gripper shuttle comprising
- a shuttle body housing of tubular construction and of relatively rigid substance, said body having a front end and a pair of oppositely aligned bores therein;
- a metal nose member at said front end of said housing having inwardly and rearwardly facing inclined surfaces thereon engaging at least part of said front end of said housing;
- a spigot secured to said nose member and mounted within said housing, said spigot having a bore therein normally disposed nearer said surfaces of said nose member than said bores of said housing;
- resilient means disposed in said pair of bores and/or on said surfaces;
- and
- a pin passing through said bores of said housing and said spigot to connect said housing to said spigot while compressing said resilient means to place said housing in compression between said pin and said surfaces.
