Abstract
A heald frame formed in a square configuration by joining a pair of frame staves forming the top and bottom frame members and a pair of side stays forming the right and left frame members has generally four flexibly constructed joint joints of the frame staves and side stay to prevent breakage which may result during the operation on a high-speed loom. A projection at the end of the side stay is disposed interiorly with a spacer mounted thereto within the hollow frame stave and then secured with the spacer which is depressed inwardly so as to have a deformed shape, whereby the projection of the side stay and the inner wall of the frame stave will be securely joined by the spacer.
Claims5
A heald frame for looms, comprising:
- a pair of frame staves having hollow ends;
- a pair of side stays each having projections at their ends for joining each of said projections with a spacer mounter thereto for disposal interiorly together with a retaining member within a hollow end of the frame stave;
- a plurality of resilient spacers each disposed on and substantially surrounding a said projection respectively, each spacer having a resting shape wherein it is insertable into said hollow end, and a deformed shape;
- a cushioning member positioned between an edge of each said frame stave hollow end and a respective side stay;
- a retaining member directly connected to each spacer, the retaining member being pressed against the spacer to provide said deformed shape of said spacer;
- and
- means for exerting pressure upon each retaining member thus to depress the spacer and provide said deformed shape to hold the projection securely and, at the same time, remain depressed intensively against the inner wall at the hollow end.
