Abstract: A sheet of glass or similar material is moved to and in the cutting area of the apparatus by sheet gripping assemblies that engage and grip an edge portion of the sheet, and that undergo precise controlled movement. A fluid-jet discharging nozzle moves above the sheet along a path of travel normal to the sheet movement. Belts supportively underlying the sheet are driven sufficiently in unison therewith to minimize possible scratching or other marring of the glass. To the same end, the lower portion of the fluid-jet nozzle is of tapered shape. Sheet-engaging clamps of the gripping assemblies are moveable in a manner adapted to prevent damage to the glass sheets engaged thereby. Positioning structure may be provided for receiving and positioning the glass sheets preparatory to the cutting thereof.

Abstract: A sliding shoe or member for a pusher or reheating furnace for the sliding transport of substantially bar-shaped heated objects has an essentially U-shaped profile or sectional shape and is provided with downwardly protruding legs for the laterally guided support of the sliding shoe on a rail. At its inner web side the sliding shoe is provided with sliding elements which consist of a material which has a coefficient of friction sufficient for an essentially wear-free feed or advance of the sliding elements and thus the shoes at the central region of the rail at a furnace temperature of about 600.degree. to 700.degree. C. These measures afford sliding characteristics which make it unnecessary to provide additional lubrication between the sliding shoes and the rail.

Abstract: The present invention discloses a way of separating and treating the covered surfaces of stacked articles in abutting face-to-face contact. It is particularly applicable to stacked planar articles, those having a relatively small width dimension and at least two substantially parallel surfaces in abutting contact, such as metal beverage container closures. The articles are pushed through a curvilinear path defined by a constant width trackwork of a herein specified design, allowed to pivot on the portions of the articles in proximity to the shorter radius whereby fan-like separation of the portions in proximity to the longer radius occurs, and treating medium, such as heated air, is directed toward the separated portions. Greater uniformity in treatment may be obtained by rotating the articles, at least once, as they traverse the curvilinear path. A preferred embodiment designed to dry the sealant on metal beverage container closures is disclosed herein.

Each of the first cross members contains a first pair of open top spaces and each of said second cross members contains a second pair of open top spaces, the first pair of spaces being disposed laterally inwardly of the second pair of spaces. A pair of serpentine wear strips are provided to support the chain, each of the wear strips extending along the length of the series of cross members, alternately through an associated one of the first cross member spaces and through an associated one of the second cross member spaces. Each wear strip is axially slidably and easily removably mounted on the series of cross members.

Abstract: An accumulator conveyor has rollers forming an object transport surface and an endless flexible drive member. The drive member, at intervals, rests on and travels over support members each resiliently supported for vertical movement. Each support member has a generally circular drive member support having a flattened area of reduced radius and also a circular feeler extending into the path of objects on the transport surface. An object held stationary over the feeler depresses it and the drive member, with the drive member continuing to rotate until the flattened area is uppermost, dropping the drive member and terminating its drive engagement with the object above.

Abstract: A transport or conveyor mechanism of simple construction and reliable operation for moving paper money bills or currency. Paper money bills are fed from a stack of bills to the transport device and conveyed by the device to a remote delivery point.
