Abstract
Abstract A stack of workpiece fabrics carried on a mobile cart is brought to a sewing machine having a work surface spaced above the table surface of the cart on which the fabric is supported. An air powered lift mechanism mounted on the sewing machine and engaged with the cart elevates the cart to an upper tilted position for easy transfer of the work from the table surface of the cart to the work surface of the sewing machine. Fabrics on which work has been completed may be transferred by air powered apparatus to a cart for transport to another station.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
In combination with a machine having a base and a horizontal work surface adapted to support a workpiece thereon, apparatus for transferring the workpiece between said work surface and a first transport device, including a frame attached to said base, vertically movable lift means engageable with said first transport device for elevation thereof from a lower horizontal position spaced below the work surface, link means interconnecting the frame and the lift means for constraining movement of said first transport device between said lower position and an upper tilted position downwardly inclined relative to said work surface, and power operated means connected to the link means for displacement of said first transport device to said upper position to enhance transfer of the workpiece to the work surface, said link means comprising a pair of link elements pivotally interconnected between the frame and the lift means in non-parallel relation to each other.
Claim 2
Dependent Claim
150 words
In combination with a machine having a base and a horizontal work surface adapted to support a workpiece thereon, apparatus for transferring the workpiece between said work surface and a first transport device, including a frame attached to said base, vertically movable lift means engageable with said first transport device for elevation thereof from a lower horizontal position spaced below the work surface, link means interconnecting the frame and the lift means for constraining movement of said first transport device between said lower position and an upper tilted position downwardly inclined relative to said work surface, and power operated means connected to the link means for displacement of said first transport device to said upper position to enhance transfer of the workpiece to the work surface, said link means comprising a pair of link elements pivotally interconnected between the frame and the lift means in non-parallel relation to each other.
Claim 3
Dependent Claim
80 words
The combination of claim 1 wherein said apparatus further includes latch means mounted on the base for holding a second transport device in operative relation to the work surface, clamp means engageable with the workpiece while supported draped over the work surface for clamping of the workpiece to said second device and work displacing means engageable with the workpiece while clamped to said second device for transfer of the workpiece relative to said clamp means onto said second transport device.
Claim 4
Dependent Claim
20 words
The combination of claim 2 wherein said machine includes fabric stitching means and said workpiece is a stack of fabrics.
Claim 5
Dependent Claim
34 words
The combination of claim 3 wherein said lift means comprises a vertically elongated column to which the link means is connected, and an elongated hook element connected to the column and extending transversely thereof.
Claim 6
Dependent Claim
55 words
The combination of claim 4 wherein said first transport device comprises a mobile cart having a table surface on which the workpiece is adapted to be carried, said table surface being elevated to the level of the work surface and in abutment therewith in the upper position to which said first transport device is displaced.
Claim 7
Dependent Claim
34 words
The combination of claim 1 wherein said lift means comprises a vertically elongated column to which the link means is connected, and an elongated hook element connected to the column and extending transversely thereof.
Claim 8
Dependent Claim
55 words
The combination of claim 1 wherein said first transport device comprises a mobile cart having a table surface on which the workpiece is adapted to be carried, said table surface being elevated to the level of the work surface and in abutment therewith in the upper position to which said first transport device is displaced.
Claim 9
Dependent Claim
168 words
In combination with a machine having a base and a horizontal work surface adapted to support a workpiece thereon, apparatus for transferring the workpiece between said work surface and transport device having a supporting surface, including a frame attached to said base, vertically movable lift means for elevating the transport device from a lower position wherein said supporting surface is spaced substantially parallel to and below the work surface to an upper tilted position abutting the work surface, said lift means comprising a vertical lift column engageable with the transport device in spaced relation below the supporting surface, link means interconnecting the frame and the lift column for constraining movement of the transport device between said lower position and said upper tilted position wherein said supporting surface is downwardly inclined relative to said work surface, and power operated means connected to the link means for displacement of the transport device to said upper position to enhance transfer of the workpiece from the supporting surface to the work surface.
Claim 10
Dependent Claim
168 words
In combination with a machine having a base and a horizontal work surface adapted to support a workpiece thereon, apparatus for transferring the workpiece between said work surface and transport device having a supporting surface, including a frame attached to said base, vertically movable lift means for elevating the transport device from a lower position wherein said supporting surface is spaced substantially parallel to and below the work surface to an upper tilted position abutting the work surface, said lift means comprising a vertical lift column engageable with the transport device in spaced relation below the supporting surface, link means interconnecting the frame and the lift column for constraining movement of the transport device between said lower position and said upper tilted position wherein said supporting surface is downwardly inclined relative to said work surface, and power operated means connected to the link means for displacement of the transport device to said upper position to enhance transfer of the workpiece from the supporting surface to the work surface.
