Loom

Claim 2

A loom including a dobby comprising, in combination, a warp beam in the base of the loom, a tensioning roller located lower than the axis of the warp beam, healds disposed above said tensioning roller for guiding the warp threads to form a shed limited at its lower end with a reed, frames for said healds, means for picking the weft threads through the shed, a sand roller disposed at the upper part of the loom for taking up the woven fabric, the medial plane of the shed being directed from said tensioning roller to said sand roller and enclosing with a vertical plane an angle between 0* and 25*, a cloth beam whose axis together with the axis of the warp beam are located in a plane substantially parallel to the median plane of the shed, actuating means for the frame of said healds, said actuating means being located in the same plane with the frames which they are extended with on a substantial part of the depth of the loom, the actuating means of the lowest of said frames being located substantially tangentially to the upper part of the warp beam, the actuating means of the highest of said frames being located tangentially to the upper part of the cloth beam, frame guide plates disposed centrally of said frames, each of said frames including an arm, said guide plates covering the arm of the frame to be guided in all positions thereof, a plurality of spacer members disposed outside the frame and supporting one end of said plates, a removable spacer disposed within the frame for supporting the opposite end of said guide plates, said plurality of spacer members being thicker than the arm of the frame to be guided so that said arm may move freely between said plates, a baseplate, and means connecting said spacer members and said guide plates to said baseplate.

Claim 3

A loom including a dobby comprising, in combination, a warp beam in the base of the loom, a tensioning roller located toward the outside of the warp beam and with its axis lower than the axis of the warp beam, healds disposed above said tensioning roller for guiding the warp threads to form a shed limited at its lower end with a reed, frames for said healds, means For picking the weft threads through the shed, a sand roller disposed at the upper part of the loom adjacent the same side of the loom as said tensioning roller for taking up the woven fabric, the median plane of the shed being directed from said tensioning roller to said sand roller to define a substantially flat plane therebetween enclosing with a vertical plane an angle between 0* and 25*, a cloth beam mounted in the top of the loom behind said sand roller the axes of said cloth beam and warp beam located in a plane substantially parallel to said median plane of the shed, actuating means for moving each of the frames of said healds, said actuating means being located in the same plane with the frames which they are extended with on a substantial part of the depth of the loom, said actuating means of the lowermost of said frames being located substantially tangentially to the upper part of the warp beam and said actuating means of the highest of said frames being located tangentially to the lower part of said cloth beams, first and second lever means, said first lever means connected at one end to said actuating means and connected at its other end to said second lever means, said second lever means connected to said dobby, a spindle on which said first lever means is pivotally mounted, said spindle being substantially parallel to the direction of movement of said frames, whereby the movements of said dobby are transmitted to said actuating means.

Claim 4

A loom including a dobby comprising, in combination, a warp beam in the base of the loom, a tensioning roller located toward the outside of the warp beam and with its axis lower than the axis of the warp beam, healds disposed above said tensioning roller for guiding the warp threads to form a shed limited at its lower end with a reed, frames for said healds, means For picking the weft threads through the shed, a sand roller disposed at the upper part of the loom adjacent the same side of the loom as said tensioning roller for taking up the woven fabric, the median plane of the shed being directed from said tensioning roller to said sand roller to define a substantially flat plane therebetween enclosing with a vertical plane an angle between 0* and 25*, a cloth beam mounted in the top of the loom behind said sand roller the axes of said cloth beam and warp beam located in a plane substantially parallel to said median plane of the shed, actuating means for moving each of the frames of said healds, said actuating means being located in the same plane with the frames which they are extended with on a substantial part of the depth of the loom, said actuating means of the lowermost of said frames being located substantially tangentially to the upper part of the warp beam and said actuating means of the highest of said frames being located tangentially to the lower part of said cloth beams, first and second lever means, said first lever means connected at one end to said actuating means and connected at its other end to said second lever means, said second lever means connected to said dobby, a spindle on which said first lever means is pivotally mounted, said spindle being substantially parallel to the direction of movement of said frames, whereby the movements of said dobby are transmitted to said actuating means.

Claim 5

A loom according to claim 2 wherein said actuating means includes a series of interconnected links and levers disposed in substantially horizontal superposed planes and said first lever means moves in a juxtaposed vertical plane in a direction perpendicular to the movement of the frames.

Claim 6

A loom according to claim 2 wherein said actuating means includes a series of substantially horizontal stacked pulleys for each of said frames and a cable sheaved over each series of said pulleys, said cable passing from one of the series of said pulleys to a pulley integral with said first lever means, said first lever means moving in a juxtaposed vertical plane in a direction perpendicular to the movement of the frames.
