  • Patent number: 4991695
    Abstract: This relates to a hydraulic brake system particularly adapted for use in conjunction with large rotating masses. The system includes at least two calipers which are widely spaced. In accordance with the system, there is positioned adjacent each caliper a solenoid valve and there is at each valve a constant supply of hydraulic fluid under pressure so that when the valve is actuated there is an immediate supplying of hydraulic fluid under pressure to each caliper. The arrangement permits an early response time as compared to systems wherein the system must be pressurized from a remote source.

  • Patent number: 4626190
    Abstract: Blow molding apparatus wherein halves of a split mold are carried by mold carriers. The mold carriers normally include one fixed mold carrier and one movable mold carrier which is positioned by way of a cam follower and associated cams. When the mold closes, the mold carriers come into closed relation with respect to one another. The mold carriers are provided with locking flanges which are engaged by C-shaped retaining members so as to prevent the material separation of the mold carriers. Then a pressure pack within the mold carriers is expanded so as to clamp the mold halves together. A simplified linkage is provided for, in conjunction with a cam follower and cams, to move the retaining members between retaining positions and release positions. The cams are mounted for adjustment normal to the direction of movement of the mold carriers and may be adjusted in that normal position to compensate for adjusted positions of the mold carriers in accordance with different size molds.

  • Patent number: 4605368
    Abstract: This relates to a blow molding apparatus of the rotary wheel type and particularly relates to supplying fluids, such as air, vacuum and water to a mold half and its associated carrier in a manner which permits the reciprocation of the mold half and associated carrier between a mold open position and a mold closed position. This is facilitated by the use of short lengths of hose which are attached to respective manifolds by swivels. The swivels permit the ends of the hose to change their angular relationship as one end of each hose moves relative to an opposite end of the hose. Adjacent ones of the hoses are located in adjacent parallel planes and are initially bowed in one direction and reverse their direction of bow as movable ends of the hoses move beyond fixed ends of the hoses. The carrier for the movable mold half has associated therewith a cam follower for engaging a cam which effects the opening and closing of the mold.

  • Patent number: 4397625
    Abstract: This relates to a labeller for applying labels to the cavities of mold halves of a rotating blow molding machine whereby when a parison is blow molded within each mold thereof to form a bottle or like hollow article, each such article will be provided with at least one and preferably two labels. The labeller is provided with pick-up heads to pick up labels from two opposed hoppers and then move the labels in between the paths of rotation of mold halves and with proper timing advance the labels into the mold half cavities and discharge them on the walls of the mold cavities. Control circuitry is provided for the automatic operation of the labeller whereby not only can the labeller operate without interference with the moving mold halves, but also accurately position the labels within the cavities. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

  • Patent number: 4359314
    Abstract: This relates to a transfer apparatus for transferring labels from a label stack into the cavity of a moving mold half. The transfer device includes a pivotally mounted arm which has mounted on its free end a transfer head which swings about the arm so that for a limited movement of the arm there can be a much greater movement of the transfer head. Thus, the transfer head may rapidly enter and rapidly depart from a mold cavity so that a label may be seated in the mold cavity very quickly without requiring any slowdown of the movement of the mold half. The transfer head is provided with vacuum heads which operate to effect a peeling of a label from its associated stack beginning along one edge portion of the label so as to assure that only a single label is picked up from the stack.

  • Patent number: 4355967
    Abstract: This relates to a transfer device for transferring labels from a stack into mold cavities without modifying the operation of the existing molding machine. The transfer device includes a pivotally mounted arm which is positioned and pivoted by a linear drive shaft positioned by a cam carried by an associated mold half. The transfer head is mounted on the arm for pivoting about the arm by way of an actuator which includes drive pulleys coupled by drive belts. The transfer head includes vacuum heads, one of which has associated with a suction cup thereof bellows for retracting the suction cup after the suction cup has sealed with the label to initiate peeling of the label from the stack. The suction cup is guidingly mounted so as to maintain its orientation at all times.

  • Patent number: 4080146
    Abstract: This disclosure relates to a mold construction particularly adapted for the blow molding of hollow articles having configurated bottoms. The mold is split longitudinally of the article and includes first and second halves each having a separate end portion. The end portions are interconnected so that when the mold is open, both end portions are retained with one mold half with one end portion moving relative to its respective mold half both longitudinally and transversely for both moving transversely with a molded article and longitudinally away from the molded article so as to first completely release the molded article from one mold half, and the end portion of the other mold half being thereafter movable longitudinally with respect thereto to separate the other end portion from the molded article and thus permit the ejection of the molded article from the mold. The molds are arranged in end-to-end substantially touching relation wherein there is a minimum of waste material between adjacent molded articles.
