Patent number: 4356744Abstract: Dome-shaped shoulder pad discs are placed in face-to-face overlying relationship and loaded in segmented carriers of a surface conveyor system. Each carrier moves its shoulder pad discs to a first station where the material is cut between the segments of the carrier and formed into a leading stack of shoulder pads, a following stack of shoulder pads, and an intermediate stack of waste material. The carrier is moved to a second station where the intermediate stack of waste material is pushed downwardly between the segments of the carrier and ejected. The leading segment of the carrier is moved to a third station where the leading stack of shoulder pads is picked from the leading segment of the carrier and moved to a stacker, and then the following segment of the carrier is moved to the third station where its stack of shoulder pads is picked from the following segment of the carrier and moved to the stacker. The stacker forms the shoulder pads in a vertical stack.Type: GrantFiled: June 19, 1980Date of Patent: November 2, 1982Assignee: Oxford Industries, Inc.Inventors: C. Ray Hamilton, William O.

Patent number: 4341334Abstract: A conveyor section advances a ribbon into a cutting station where sheets are severed from the glass ribbon. The sheets are advanced onto downstream conveyor rolls where the sheet is accelerated for a given period of time to space the trailing edge of the sheet from the leading edge of the ribbon, i.e., leading edge of the next sheet to be severed from the ribbon. When a predetermined number of spaced sheets are on the conveyor rolls, the conveyor rolls are accelerated to a speed greater than the ribbon conveying speed and spacing speed to move the group of sheets downstream along the conveyor section into additional working stations.Type: GrantFiled: June 9, 1980Date of Patent: July 27, 1982Assignee: PPG Industries, Inc.Inventor: David A.

Patent number: 4328725Abstract: Prior to the forming of bar material, without creating internal stresses, on transverse transport presses, bars are sub-divided into sections of equal volume, the end-pieces of each bar having to be discarded before further processing. To provide for the automatic and material-saving discarding of the end pieces, two light barriers are installed in the feed zone of the bars, the distance (a) between these light barriers being newly stored in a microprocessor as each bar is fed in, and this distance being converted, by calculation, to three further distances (b, c, d). By reference to these data, the microprocessor controls the discarding operation, with one, or at the most two, section lengths being discarded per bar, according to whether the interface between two successive bars is located in the central region of the section length in question, or in one of its two end-regions.Type: GrantFiled: September 17, 1980Date of Patent: May 11, 1982Assignee: Hatebur UmformmaschinenInventor: Rene Gschwend

Patent number: 4326439Abstract: Each row of uncured brick is arranged with a longitudinal axis extending transversely across the width of a push-off table and is serially pushed by preceding rows past the end of the table. An elevator device registers a first platform with the end of the push-off table to receive a first row(s) and a second platform vertically spaced therefrom to receive a second row(s). The upper and lower row(s) are then simultaneously pushed from the elevator onto the upstream end of a marshalling table to form a two layer stack. A first shuttle device includes a plurality of shorter, longitudinally extending bars interspersed between the bars forming the marshalling table. The bars of the shuttle device are vertically movable between a first position beneath the level of the marshalling table bars, and a second position above such level supporting the bricks thereon.Type: GrantFiled: March 26, 1980Date of Patent: April 27, 1982Assignee: Clarksville Machine Works, Inc.Inventors: Bob L.

Patent number: RE30645Abstract: A method and apparatus for automatically cutting wrappers or the like from metal sheets. A metal sheet is conveyed in the x-direction to a cutting position wherein a pair of cutting blade (i.e., shears) assemblies cut edge portions from the metal sheet to form a cut wrapper or the like having longitudinal edges. The cutting assemblies are movable in the y-dimension--transverse to the x-direction--and are also angularly movable. From the cutting position the cut wrapper is continuously conveyed to a notching position wherein notching assemblies also movable in the y-dimension may form notches in the longitudinal edges of the cut wrapper. At a further point in the x-direction, an edge deforming position may be provided including edge deforming apparatus that also is movable in the y-dimension. Flexible elongated members or the like support the metal sheet spaced from its conveyor during conveying to prevent damage to the conveyor by the cutting or notching assemblies.Type: GrantFiled: July 6, 1979Date of Patent: June 16, 1981Assignee: Potomac Applied Mechanics, Inc.Inventor: James H.
