  • Patent number: 4164860
    Abstract: A reciprocal ram at commencement of a forward stroke engages a cup-shaped article carrying it through metal working dies and against a doming die at reversal into a rearward stroke immediately followed by stripping of the article from the ram. The ram has an internal chamber constantly fed pressurized air through a rearward restricted orifice, the chamber opening freely of the ram forward end portion and internally of the article when thereon. By preselecting orifice size, chamber and article volumes matched with air pressure, a predetermined volume of air at predetermined pressure is confined in the ram forwardly against the article immediately prior to stripping and preferably engagement of the article by an external stripper results in an internal stripping assist by the confined pressurized air, the increasing exposed volume of the article increasing the air confinement volume reducing the air pressure progressively to substantially atmospheric at completion of article stripping.

  • Patent number: 4143827
    Abstract: A roll holder of the type for mounting split-core rolls of tissue is positioned in a dispenser moveable from an upper dispensing position to a lower exhausted position. A latch retains the roll holder in the dispensing position until tissue exhaustion permits relative movement between the split-core parts with consequent roll holder part movement to release the latch for movement of the roll holder to the lower exhausted position. The improvement includes blocking members at roll holder opposite ends normally retained inactive permitting the foregoing latch release by presence of the split-core parts, but automatically moving to active preventing latch release upon a lack of core retention. This means that the split-core must remain for proper roll holder functioning, and also that a solid core roll cannot be used with core stripping to cause roll holder functioning, in either case avoiding core stripping from the roll holder which can result in littering.

  • Patent number: 4108202
    Abstract: An end of an inlet tube communicates through a tank wall with a water supply and an inner end of the inlet tube communicates through a float controlled valve with a generally vertically downwardly extending outlet tube. Thus, the tank water level through the float controls closing and opening of the valve admitting water through the inlet tube, through the valve and down the outlet tube flowing into the tank from the outlet tube lower end. The outlet tube is selectively vertically adjustable to adapt to various depths of tank by being formed of telescoped parts normally retaining a determined telescoping by a projection of one part being radially interengaged in a groove of the other part. Depending on the particular construction, the tube part telescoping may be selectively varied by either relative rotation between the parts or by disengaging and reengaging the interengagement between the parts. Through a slot and lock collar arrangement, the tube parts may be totally telescopically separated.
