Patent number: 4580773Abstract: This suction foot or "sheet sucker" has a cylinder and a hollow piston fitted in the cylinder. The piston has a piston rod whose tip protrudes downwardly from the cylinder to apply suction to the top sheet of stock in a small press. The cylinder is supported from and moved by a hollow support rod that is connected with the suction system of the press. The piston and rod are spring-loaded upward relative to the cylinder. The hole in the support rod communicates with a point in the cylinder cavity below the piston. Applied suction consequently draws the cylinder and rod downward, against the spring action, in effect telescoping the suction foot tip outwardly toward the stock. When a sheet of stock closes the bottom end of the hollow piston and rod, pressure on the cylinder is equalized and the suction foot tip retracts, raising the stock for travel into the press. The necessary air communication is effected by several fine air passageways in the cylinder side wall and top wall.Type: GrantFiled: July 2, 1984Date of Patent: April 8, 1986Inventor: Richard Minkle

A sector of a cylinder has the same axis as the rotating mirror. The material to be scanned is mounted on the top of a flexible plate. The flexible plate may rest flat on a table outside of the area scanned. The flexible plate may then be pushed into the cylinder with the bottom face of the flexible plate in contact with the inner side wall of the sector of the cylinder. When the flexible plate has reached the proper position in the cylinder, the bottom face of the plate of the flexible plate is held in position against the inner wall of the sector of the cylinder by suction, so that scanning may proceed.Type: GrantFiled: June 2, 1982Date of Patent: October 23, 1984Assignee: Crosfield Data Systems, Inc.Inventor: Ernest M. Rossini

Patent number: 4479148Abstract: The transport, that carries the material to be scanned to and from scanning position, is held against its support by suction. After the transport has been moved into scanning position the suction is applied progressively starting at one end of the transport and continuing to the other end. A squeegee roller presses the transport against its support. This roller passes over the portion of the transport to which suction has just been applied, but prior to the time that suction is applied to the next section of the transport.Type: GrantFiled: June 2, 1982Date of Patent: October 23, 1984Assignee: Crosfield Data Systems, Inc.Inventors: Wah Sheck, Daniel T. Beasley, Walter E. Myles

Patent number: 4403770Abstract: A signature collating machine having a plurality of sequentially situated signature supply stations whose common floor rises via an electronic sensor to maintain signature stacks at operable heights. Above each supply station is a suction delivery assembly, each of said assemblies having a suction port housing and a suction port extending therefrom for engagement with a signature. The machine further has traveling collector rods which sequentially gather signatures engaged with respective suction ports. An actuator is provided which causes upward movement of a suction delivery assembly, and consequent positioning of a signature for subsequent collating, upon suction port engagement with a signature. Circuitry is provided which causes collector rod travel to cease if any suction port ahead of a collector rod is not engaged with a signature, thus eliminating accidental non-inclusion of a signature.Type: GrantFiled: March 22, 1982Date of Patent: September 13, 1983Inventors: Leonard Ferguson, Jack W. Mefford

Patent number: 4382593Abstract: An automatic vacuum document feeder particularly adapted for feeding sheet-like documents in seriatim from a stack onto a utilization device, such as the document platen of a convenience copier. The documents are disposed in a tray. A vacuum lifter descends and lifts the topmost document along a vertical path to a position above the stack and beyond the bottom surface of a vacuum transport. The vacuum transport is disposed in a plane perpendicular to the vertical path of the vacuum lifter. The vacuum transport strips the document from the vacuum lifter and transports the document to the utilization device. The entire system is configured so that there is no relative motion occurring between the document being transported and the transport hardware. A document restraint device, including air jets and stripper fingers, coact with the stack to eliminate double feed.Type: GrantFiled: August 4, 1980Date of Patent: May 10, 1983Assignee: International Business Machines CorporationInventors: Mark A. Beran, Donald F. Colglazier

Patent number: 4369962Abstract: An apparatus for feeding a single sheet from the bottom of a stack of sheets to a station for performing subsequent operations on the sheet. The apparatus is comprised of a magazine to receive a stack of sheets having a bottom support and upstanding walls, the bottom support having an opening therein through which the lower most sheet can be removed. A suction nozzle is provided below the magazine opening and a vacuum surface is provided below the suction nozzle. A first pivot arm is attached to the suction nozzle and a second pivot arm is attached to the vacuum surface. A sheet receiving and feeding apparatus below the magazine receives and feeds the sheet to the station which performs the subsequent operation on the sheet. The pivot arm is pivoted to (i) raise the suction nozzle to engage the surface of the lower most sheet, and subsequently (ii) lower the suction nozzle to engage the bottom surface of the sheet with the vacuum surface.Type: GrantFiled: February 17, 1981Date of Patent: January 25, 1983Inventor: Murray Spiro

Patent number: 4359314Abstract: This relates to a transfer apparatus for transferring labels from a label stack into the cavity of a moving mold half. The transfer device includes a pivotally mounted arm which has mounted on its free end a transfer head which swings about the arm so that for a limited movement of the arm there can be a much greater movement of the transfer head. Thus, the transfer head may rapidly enter and rapidly depart from a mold cavity so that a label may be seated in the mold cavity very quickly without requiring any slowdown of the movement of the mold half. The transfer head is provided with vacuum heads which operate to effect a peeling of a label from its associated stack beginning along one edge portion of the label so as to assure that only a single label is picked up from the stack.Type: GrantFiled: September 30, 1980Date of Patent: November 16, 1982Assignee: The Continental Group, Inc.Inventor: Ernest W.
