    摘要： A fail-safe locking device for reel support systems is described which is suitable for use with reels such as those used with wire stranders and similar machines. In the embodiments described, a pintle supporting shaft member is normally biased by a spring to an extended position. A safety plunger is provided which has a stepped exterior surface so as to define a recess or step. The safety plunger is normally biased by a spring to a disabling position to urge a blocking member, such as a hardened steel ball or sphere, into the path of movement of an abutment surface of the shaft member to automatically and positively lock the shaft member and the pintle. In the locked condition, the plunger member and, therefore, the pintle, cannot accidentally release the reel. The shaft member and the safety plunger are provided with bearing surfaces against which a fluid medium under pressure may be applied by an operator of the machine to, firstly, move the safety plunger from the disabling to an enabling position to permit the ball or sphere to drop into the recess or notch and, therefore, out of the path of movement of the shaft member abutment surface. Once freed, the plunger member is urged by the fluid medium under pressure to a retracted or releasing position. Two opposing pintle assemblies may be mounted on a cradle typically used in wire stranders, and pneumatic pressure is used by the operator to release the fail-safe locking system to accept or release a reel from the cradle. Electrical means may be used for monitoring the position of the safety plunger and for disabling the machine or issuing an alarm upon movement of the safety plunger to its enabling position and, thereby, permitting the plunger member and pintle to move to a retracted position. The fail-safe locking device is also shown on other reel-supporting systems such as bobbin supporting shafts.

    摘要： A strand carrier for a strand fabricating machine includes a support structure and a shaft mounted thereon. A hub is mounted for rotation around the shaft for receipt of a bobbin of strand thereon for common rotation about the shaft. A helical clutch spring includes a first end secured to the support structure so that it closely encircles an outer cylindrical surface of the hub to restrict rotation thereof. A clutch release sleeve is rotatably mounted on the support structure around the clutch spring and receives the other end of the spring in an opening therein so that rotation of the clutch release sleeve in a first direction will tend to unwind the clutch spring to reduce friction on the hub. A control lever pivotally mounted on the support structure has a first section which includes a strand guide thereon and is connected to the sleeve. The lever is biased in a direction tending to rotate the sleeve in an opposite direction from the first direction. A plurality of additional strand guides are mounted on the support structure to direct the strand being unwound from the bobbin to and around the strand guide of the first section to apply a resulting force on the strand guide during unwinding in a direction in opposition to the biasing of the lever.

    摘要： A wear ring seal construction for a carrier used in a pneumatic tube system, particularly a carrier of the type having a pair of wear rings surrounding the carrier body spaced from each other and from the ends of the carrier. The wear rings each are formed of a plurality of ring layers or laminations of a special material which flexes easily to accommodate out-of-roundness of the tube cross section, and indentations or sharp projections in the interior of the tube wall. The ring layers have alternately large and small diameters and different thicknesses and the arrangement of ring layers preferably is symmetrical about a center plane perpendicular to the ring axis. The wear rings are replaceable and have a minimum contact with the tube inner surface during travel through the tube while providing an efficient seal. Further, the minimum surface contact between wear ring and tube results in a miminum area on the edges of the seal rings for the collection of material which can soil the hands of a user manipulating the carrier when removed from the tube.

    摘要： Mechanism for controlling the tension of a strand from a spool of strand material on a strand fabricating machine having a ''''work center'''' toward which a tensioned strand is incrementally released. The spool is carried by a spool holder having a base housing a spool release mechanism. The mechanism of the invention provides an actuator means for releasing the spool for rotation when the strand tension reaches a desired value.
