Abstract
Abstract An apparatus for sewing pockets on garments which includes a workholder nipper, a magnetic drive system for causing said nipper to move along a predetermined sewing contour, a doubleacting pneumatic cylinder connected to a support plate adapted to carry out linear movements on suitable guides and on which there is fastened a magnetic template of the magnetic drive system for the workholder nipper to effect the displacement of the workholder nipper from a sewing position to a loading position and from the loading position to the sewing position, and a loading system which includes pneumatic motor actuating blades adapted to cooperate with cylinders having stems so shaped as to clamp one side of a piece of garment stacked below the cylinders and to lift the garment to a height of the blades in order to push the fabric under the work nipper to a predetermined and well defined position.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
234 words
An apparatus for sewing pockets on garments comprising a supporting frame, a table top fixed to said frame, a sewing machine fixed to said table top; an electric motor fixed to said frame for actuating said sewing machine, two parallel guides fixed to said frame, a slide bushed to one of said guides and slidable along the other, two blocks rigidly fastened to said slide, two superimposed parallel guides positioned orthogonally to said parallel guides the upper of which is fastened to said blocks and the lower of which is fastened to said slide, a slide positioned on and slidable along said superimposed parallel guides, a pivotable pocketholder nipper carried by said last mentioned slide, a support plate positioned on said table and movable with said nipper, a motor reducer fastened to said last mentioned slide having a shaft of magnetizable material, two parallel cylindrical bars mounted on said frame parallel to said parallel guides, a support block mounted for displacement on said bars, an electromagnetic template mounted on said support block and contactable by said magnetizable shaft, a pneumatic cylinder fixed to one end of one of said bars and connected to said support block to displace said support block and thus the pocketholder nipper and said support plate from an operative position in which the pocket is sewn on the garment to a loading position in which a new garment is loaded.
Claim 2
Independent Claim
234 words
An apparatus for sewing pockets on garments comprising a supporting frame, a table top fixed to said frame, a sewing machine fixed to said table top; an electric motor fixed to said frame for actuating said sewing machine, two parallel guides fixed to said frame, a slide bushed to one of said guides and slidable along the other, two blocks rigidly fastened to said slide, two superimposed parallel guides positioned orthogonally to said parallel guides the upper of which is fastened to said blocks and the lower of which is fastened to said slide, a slide positioned on and slidable along said superimposed parallel guides, a pivotable pocketholder nipper carried by said last mentioned slide, a support plate positioned on said table and movable with said nipper, a motor reducer fastened to said last mentioned slide having a shaft of magnetizable material, two parallel cylindrical bars mounted on said frame parallel to said parallel guides, a support block mounted for displacement on said bars, an electromagnetic template mounted on said support block and contactable by said magnetizable shaft, a pneumatic cylinder fixed to one end of one of said bars and connected to said support block to displace said support block and thus the pocketholder nipper and said support plate from an operative position in which the pocket is sewn on the garment to a loading position in which a new garment is loaded.
Claim 3
Dependent Claim
90 words
The apparatus of claim 1 further comprising a garment loader fastened to said supporting frame and formed of a support element, a horizontally positioned pneumatic motor fastened to said element, two blades fastened to said motor and actuated thereby horizontally, fabric lifting means attached to said element above said blades to lift a garment to a position whereby the garment may be pushed by said blades onto said support plate under the pocketholder nipper to a predetermined and well defined position when the pocketholder nipper is in the loading position.
