Abstract: An upholstery tack holding tool is formed with a shaft having a concave gripping surface formed transversely into the shaft. The concave gripping surface terminates in a circumferential lip that encircles a longitudinally extending concave tack receiving area at one end of the shaft opposite the flat top surface adapted for striking by a tack hammer. The tools improves control, stability, and speed of operation by enabling the operator to simultaneously grasp the lip of the tool and the head of the tack to hold the tack against the concave tack receiving portion while being inserted into the desired surface.

Abstract: A system for continuously packaging or sorting fragile articles having varying thicknesses in a stack includes a plurality of proportional shifters coupled to each of a plurality of stripping devices in an article infeed assembly. Each proportional shifter has an article gauge for measuring the height of a stack having a set or desired number of fragile articles, such as crackers or cookies. An article stripping device may be quickly and accurately adjusted in-process to measure the thickness of a set number of stacked articles contained in a given batch coming from an article infeed. The article gauge provides a measure of the height of a stack of a set number of articles sampled from an article infeed. The stack height is equivalent to the height of the stack of articles stripped by the strip feeder.

Abstract: A stapling device for automatically binding a set of sheets is formed of a needle driving unit for driving a needle in the set of the sheets; a bending unit for bending the driven needle; two pairs of front and rear guide shafts for supporting the needle driving unit and the bending unit and guiding movements of these units in a sheet width direction; and moving shafts for moving these units along the guide shafts in the sheet width direction. By disposing each moving shaft between the front and rear guide shafts, each unit can be moved in the sheet width direction stably and smoothly, and the entire device can be structured small. Also, in at least one of the units, a small space is formed for a moving mechanism for at least one of needle driving device and bending device in a sheet thickness direction, to thereby achieve a further miniaturization of the entire device.

Abstract: A bottle handling device for assisting in inserting a number of similar sized bottles into a secondary container, such as a partitionless beer carton. The device comprises a frame which, when inserted into the empty carton, provides a number of similar sized cells or compartments equal to the number of bottles which would completely fill the carton. The frame is maintained by support means above the shoulders of the bottles when located in the carton. Each bottle is inserted into, and its main body passes through, the frame until the bottle sits on the carton floor, the walls of each cell preventing a bottle in that cell from toppling over and hindering the insertion of further bottles and completion of filling of the carton. Upon completion and filling of the carton, the device is readily removed for reuse and the bottles are maintained in their upright condition by contacting adjacent bottles and the carton walls.
