  • Patent number: 7040516
    Abstract: An improved shirt pressing device for gripping both short and long-sleeved shirts. A buck having a pair of retractable arms for receiving a shirt is mounted on a base. A sleeve gripping member is provided on each retractable arm to grip the sleeve of the shirt to be pressed. Each sleeve gripping member includes a pair of clamping members for holding the cuff of a long-sleeved shirt against a cuff mount. A pair of sleeve engagement bars attached to the clamping members are adapted to grip the inside of the sleeve of a short-sleeved shirt. Thus, the retractable arms are configured to receive and hold the sleeves of both short and long-sleeved shirts.

  • Patent number: 5675918
    Abstract: A shirt cuff pressing assembly comprising an upper and lower cuff chest. The cuff chests have a forwardly protruding pressing surface defined by a protruding portion and a cut-out portion in which the cuff and pleated portion of a shirt sleeve may lay flat. The cut-out portion provides relief for the unpleated portion of a sleeve so that it is not pressed and the protruding portion allows the pleated portion of the sleeve to be pressed upon closure of the upper and lower cuff chests.

  • Patent number: 3971294
    Abstract: Apparatus for cutting an annular groove about a rotating cylindrical member includes a rotating cutter positioned in cutting relation to the outer surface of the cylindrical member and including a plurality of cutting edges, each forwardly angled in relation to the direction of rotation of the cutter. The cylindrical member and cutter rotate in the same direction so that an annular groove or channel is cut in and along the outer surface of the cylindrical member. Sealing apparatus is included for providing sealing between the outer surface of such member and the inner surface of a member overlying such first-mentioned member. The sealing apparatus is of resilient material and is seated in the channel. The sealing apparatus includes a pair of elongated ribs angled in the same direction, and in contact with each other when in such sealing situation, with the elongated side surface of one of such ribs in sealing contact with the inner surface of such overlying member.
