  • Patent number: 4219176
    Abstract: The trophy base has top and bottom members and a wall, defining a hollow interior filled with initially fluid material, such as gypsum, which is allowed to set. Bosses on the top and bottom members have bores extending therethrough, which bosses mate to minimize the initially fluid filler material from leaking out. An annular lip on one of the bosses encircles the other boss and serves substantially to eliminate fluid material from leaking out.

  • Patent number: 4212238
    Abstract: Strap feeding and tensioning apparatus is provided for use in a strapping machine to feed steel or plastic strapping in a loop around an object to be strapped and tension the strap loop about the object, providing maximum gripping force on the strap and minimum marring thereof. The apparatus includes a motor-driven drive wheel geared to a feed wheel, the drive wheel and feed wheel respectively having circumferential strap-engaging surfaces which cooperate frictionally to grip the strapping therebetween and move the strapping in a tensioning direction in response to rotation of the drive wheel. The axis of rotation of the feed wheel is shiftable about a fixed axis to accommodate movement of the feed wheel toward and away from the drive wheel, tensioning of the associated strap exerting a resultant force on the feed wheel tending to effect movement thereof about the fixed axis in a direction to increase the frictional gripping force exerted on the associated strap by the feed wheel and the drive wheel.

  • Patent number: 4211319
    Abstract: Apparatus for automatically transferring elongated rows of articles from an oven hearth conveyor moving continuously in a first direction essentially normal to the longitudinal axes of the rows of articles thereon includes an outfeed conveyor continuously moving in a second direction disposed at an obtuse angle to the first direction and having a lateral width substantially less than the length of a row of articles. An endless transfer conveyor extends between the hearth and outfeed conveyors and carries thereon pickup mechanism mounted for pivotal movement about an axis parallel to the longitudinal axes of the rows of articles for engaging and lifting a row of articles from the hearth conveyor and carrying it in a level upright condition to the outfeed conveyor without changing the orientation of the longitudinal axis of the row of articles. Cam-actuated unloading means at the outfeed conveyor engage the row of articles for removing them from the pickup means and holding them on the outfeed conveyor.

  • Patent number: 4211350
    Abstract: A wire stitching machine includes a head frame carrying a support, a staple former and a staple driver all reciprocally movable with respect to the head frame under the action of a single reciprocating drive bar coupled by crank mechanism to a rotary drive means. Wire feed rolls and a wire-supporting anvil are carried by the support. The support, staple former and staple driver are so coupled to each other and to the reciprocating drive bar that during a first portion of its drive stroke all three are moved to the associated workpiece and during a second portion of the drive stroke the support is arrested while the staple former and staple driver continue moving to form the staple and during a third portion of the drive stroke the staple former is arrested while only the staple driver continues moving to drive the formed staple into the workpiece. The anvil includes a forming shoe and is of integral one-piece construction movable as a unit between forming and driving positions.

  • Patent number: 4208001
    Abstract: Apparatus for use with an ultrasonic plastic welder in which an ultrasonic horn on a movable welding head produces sonic vibrations along a first axis generally normal to the contacting surfaces of the workpieces to be welded together, the apparatus rendering the welder suitable for welding metals. The apparatus includes a coupling member removably connected to the distal end of the horn and extending transversely thereof and having coupled thereto a workpiece-engaging member capable of adjustment along a second axis parallel to the first axis. A force-applying member is connected to the welding head and extends therefrom toward the workpieces, with the workpiece-engaging member being adjusted to contact the lower end of the force-applying member at a fulcrum point so that axial vibration of the coupling means by the horn serves to pivot the workpiece-engaging member about the fulcrum point to effect a vibration transverse to the first axis at the contacted workpiece.

  • Patent number: 4207558
    Abstract: Each alarm unit has a sensing circuit which supplies a signal in the presence of a particular problem such as smoke, heat, or equipment failure. The signal energizes an electronic switching device, to couple power to a horn which then produces an alerting tone. The output of the sensing circuit is also coupled by a resistor to electronic switching devices in the other alarm units in the system, so that the occurrence of a problem at one location activates the horn in each alarm unit.

  • Patent number: 4205543
    Abstract: A spring winder includes a base and a mandrel rotatably held against the base by a pair of mounting blocks which include aligned grooves in which the mandrel is seated. Each block is connected to the base by a pair of mounting screws which cooperate with associated compression springs for resiliently holding the mandrel between the mounting blocks and the base with a variable force. A length of spring wire is fed between a cam and washer rotatably mounted on the side of the base by means of an adjustment screw, the wire then being fed through an aperture in the adjacent end of the mandrel. The cam and washer are resiliently urged together by a compression spring for applying a drag to the wire which is variable by adjustment of the associated screw. A pin on the washer rides in a complementary groove in the cam for retaining the wire in position. As the mandrel is rotated the wire is wound thereon against the drag of the cam and washer to form a series of helical coils.
