Abstract

Abstract The apparatus is designed to grasp a length of cloth coming from a sewing machine and to drape it over a horizontal bar. A plurality of lengths of cloth can thus be stacked one above the other on a horizontal bar. Means are then provided for moving the bar out of position and moving an empty bar into position so that successive lengths of cloth from the sewing machine can be stacked. Essentially the carrying device comprises a pair of endless belts operating in contiguous relationship and driven from the same source. The endless belts are driven so that the cloth coming from the sewing machine passes between them and is carried along between the belts until a tripping bar is reached. At this point a pair of movable fingers grasps the side edges of the cloth and the stacking takes place. A frame is provided on which an elongated bar is slidably movable at right angles to the endless belts. The fingers which grasp each side edge of the cloth are mounted on this bar. As soon as the fingers grasp the cloth the bar moves at right angles to the belts along a frame. The bar on which the cloth is stacked is positioned in a separate frame mounted beneath the carrier frame for the bar. The bar carrying the fingers then moves over the rod mounted in the frame beneath it and carries the cloth over it. At a fixed position a switch is tripped and the fingers release the cloth so that it falls draped over the rod. The bar carrying the fingers then returns to its original position ready for the next piece of cloth issuing from the sewing machine. This is repeated until a sufficient amount of cloth is piled up or stacked on to the rod. The operator then presses a button and the rod is moved away to a remote position where it can be picked up. A fresh rod is now moved into position ready to receive the next piece of cloth.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 130 words
A device for stacking textile material issuing from a sewing machine comprising a pair of endless belts oppositely driven from a common source in contiguous horizontal position, the material being frictionally retained adjacent one edge between said belts, said belts carrying the material to a predetermined position, means for grasping opposite side edges of the material, said grasping means being movable at right angles to said belts to pull the material from said belts to a predetermined point at right angles to said belts, a frame adjustably positioned beneath the path of movement of said grasping means, means on said frame for supporting the material in draped position, said grasping means being activated to release the material at said predetermined point, whereby the material will drape over said supporting means.
Claim 2
Independent Claim 130 words
A device for stacking textile material issuing from a sewing machine comprising a pair of endless belts oppositely driven from a common source in contiguous horizontal position, the material being frictionally retained adjacent one edge between said belts, said belts carrying the material to a predetermined position, means for grasping opposite side edges of the material, said grasping means being movable at right angles to said belts to pull the material from said belts to a predetermined point at right angles to said belts, a frame adjustably positioned beneath the path of movement of said grasping means, means on said frame for supporting the material in draped position, said grasping means being activated to release the material at said predetermined point, whereby the material will drape over said supporting means.
Claim 3
Dependent Claim 38 words
A device as in claim 1, wherein said supporting means includes a rod positioned transversely to the line of movement of said grasping means whereby the material will drape over said rod on release by said grasping means.
Claim 4
Dependent Claim 22 words
A device as in claim 2, wherein said rod is movable on said frame when filled and replaceable with an empty rod.
Claim 5
Dependent Claim 71 words
A device as in claim 3, wherein said receiving and stacking means comprises a generally rectangular frame of angle iron construction, a plurality of receiving rods each having a roller at each end for rolling along said angle irons, an angular angle iron path for selectively moving an empty rod to material receiving position, and an angular angle iron path for moving said fully loaded rods away from said receiving position.
Claim 6
Dependent Claim 35 words
A device as in claim 1, wherein a cutter is mounted between the sewing machine and said belts to cut the thread after the material has passed the cutter to be engaged by said belts.
Claim 7
Dependent Claim 42 words
A device as in claim 1, wherein said grasping means comprises a horizontal frame, a carriage reciprocally mounted on said frame, an elongated carrier rod mounted on said carriage, and two pairs of spaced movable fingers adjustably mounted on said carrier rod.
Claim 8
Dependent Claim 42 words
A device as in claim 4, wherein said grasping means comprises a horizontal frame, a carriage reciprocally mounted on said frame, an elongated carrier rod mounted on said carriage, and two pairs of spaced movable fingers adjustably mounted on said carrier rod.
