Device for making a hinged connection between two parts in a loom

A device for coupling first and second parallel parts to a third part therebetween, the device comprising:

• at least one fastener removably mounted to the third part and the parallel parts, the fastener having a head with a frustoconical profile;
• the third part having a recess with an outer conical portion, the conical portion having an outer diameter;
• and
• at least one of the parallel parts having a circular opening with an inner diameter and a circumference, the inner diameter being smaller than the outer diameter of the conical portion so that the head of the fastener rests against said parallel part, said parallel part including openings spaced away from the circumference by a distance substantially less than the inner diameter.

A device for coupling first and second parallel parts to a third part therebetween, the device comprising:

• at least one fastener removably mounted to the bearing part and the parallel parts, the fastener having a head with a frustoconical profile;
• the third part having a recess with an outer conical portion, the conical portion having an outer diameter;
• at least one of the parallel parts having an opening with an inner diameter and a circumference, the inner diameter being smaller than the outer diameter of the conical portion so that the head of the fastener rests against said parallel part;
• means for transmitting force coupled to the parallel parts;
• and
• a cylindrical rod fitted within the force transmitting means.

A heald rod of a loom having a device for making a hinged connection between first and second parallel parts and a third part, the device comprising:

• a bearing part rotatably coupled to the third part and disposed between the parallel parts;
• a plurality of fasteners removably mounted to the bearing part and the parallel parts, the fasteners each having a head with a frustoconical profile;
• the bearing part having a cavity for each fastener, each cavity having an outer conical portion with a circumferential edge;
• and
• the parallel parts each having circular openings aligned with the conical portion of the cavities in the bearing part, the circular openings each being sized so that the parallel parts project over the circumferential edge of each conical portion, the parallel parts each having an inner surface in contact with the bearing part, the inner surfaces being parallel to the bearing part over their entire extent so that the bearing part may be removed without effectively changing the distance between said inner surfaces.

A device for coupling first and second outer parts to a third part therebetween, the device comprising:

• a plurality of fasteners removably mounted to the third part and the outer parts, each fastener having a head with a frustoconical profile;
• and
• the third part having a cavity for each fastener, each cavity having an outer conical portion with a circumferential edge;

A device for coupling first and second outer parts to a third part therebetween, the device comprising:

• a plurality of fasteners removably mounted to the third part and the outer parts, each fastener having a head with a frustoconical profile;
• and
• the third part having a cavity for each fastener, each cavity having an outer conical portion with an outer diameter;
• the outer parts each having a circular opening with an interior surface, the interior surface having an inner diameter that is smaller than the outer diameter of the conical portion so that the head of the fastener rests against the interior surface of the circular opening and an annular cavity is formed between the head and the third part, the outer parts being elastically deformed into the cavity by a force from the fasteners to impede loosening of the fasteners.
