  • Patent number: 4375279
    Abstract: A bobbin assembly (10) is disclosed for simultaneously dispensing a plurality of wires and controllably maintaining a predetermined tension on the wires.In the construction of a high pressure, multiple-ply, wire reinforced hose, it is necessary that each of the wires be applied at a uniform, predetermined tension. The present invention solves this problem by providing each spool assembly (12) of a multiple spool bobbin assembly (10) with an internally disposed adjustable brake assembly (22). The brake assembly (22) of the present invention imparts a controllable and uniform resistance to the rotation of a supply reel (20) in each of the spool assemblies (12). The present invention is particularly useful in the construction of high pressure hydraulic hose products.

  • Patent number: 4299396
    Abstract: A quick release seal retainer (10,11) adapted for connecting a seal segment (13) to a base (12) has a clamp member (31) positioned within a slot (29) formed between a projection (28) of a mounting block (26) and the base (12). A pair of studs (38) slidably extending through a pair of bores (37) in the projection (28) have one end connected to the clamp member (31) and the other end connected to a bar (39). In one embodiment a cam clamp mechanism (51) is connected to the mounting block (26) for locking the bar (39) and hence the clamp member (31) at a position at which the seal segment (13) is clamped against the base (12). In another embodiment an over-center toggle link means locks the bar (39) and hence the clamp member (31) at a position at which the seal segment (13) is clamped against the base (12).

  • Patent number: 4181169
    Abstract: A rim for a pneumatic tire carcass has a pair of rim portions which are securable together to form such rim. One rim portion is integral with a wheel hub and includes a plurality of pockets or guide openings formed therein. The other rim portion includes guide members which correspond to these pockets and which are positionable therein to position the rim portions relative to each other. Apparatus for separating the rim portions with the tire carcass mounted on them is disclosed, as is apparatus for pulling the tire carcass off a rim portion after the other rim portion has been separated therefrom. In another embodiment, a pair of rim portions are assembled by positioning posts fixed on one rim portion into angled slots defined by the other rim portion, and rotating one rim portion relative to the other, the posts being drawn into the slots during such rotation to draw the rim portions together.

  • Patent number: 4005896
    Abstract: Apparatus for handling a large object, i.e., for example, an annular core on which a tire carcass is to be formed, includes an annular wall positionable about the annular core, and a diaphragm associated with the inner surface of the wall and defining with the wall a chamber into which pressurized fluid may be directed. Such introduction of pressurized fluid expands the diaphragm so that such diaphragm comes into contact with and grips the core. The core may then be moved and or turned over by manipulation of the wall.

  • Patent number: 3987990
    Abstract: A workpiece support structure has a lower planar surface disposed above and parallel to an upper planar surface of a base assembly which is adapted to be supported on the forks of a fork lift truck for transporting the carrier and the workpiece. A plurality of air pockets are formed in one of the planar surfaces for receiving pressurized air from a suitable source so that the support structure floats on a cushion of air between the planar surfaces permitting substantially frictionless movement of the support structure relative to the base assembly for precision positioning of the support structure and thus the workpiece relative to the base assembly.
