Abstract: A wire-covered doffer for feeding fibers to the needles of a sliver high pile fabric knitting machine, in which the card clothing is of generally rectangular configuration and envelops the doffer roll so that the longitudinally spaced ends of the segment are disposed in tight abutting relationship to each other on the roll. A pair of circumferentially spaced clamps mounted on the doffer roll tightly secure the segment of card clothing to the periphery of the roll, stretching the segment slightly to impart a slight tension thereto. Each clamp supports a row of spaced points for impalement and retention of the segment of card clothing. Each row of points extends transversely relative to the periphery of the doffer roll, and penetrates the segment of card clothing at a location spaced a short distance inwardly from one of the two abutting ends of the segment. Threaded connectors affix the clamps to the doffer roll.

Abstract: Process and apparatus for unwinding hollow coils of wire quickly and reliably without mishaps such as jammed turns, the formation of knots or blockages, wire breakage and the like. The coils are positioned with their axes vertical and then are gripped externally by a corset element to retain the coils stationary during unwinding. Wire is withdrawn upwardly from the hollow of the coil and slides over a pressure device en route to a fixed eyelet and a rotatable drum disposed above the coil. The pressure device exerts pressure on the top of the coil to stabilize the coil during unwinding, and increases slightly the curvature of the unwinding turns of wire to facilitate withdrawal. Actuator devices are provided for opening and closing the corset element and for raising and lowering the pressure device. Two or more apparatuses may be provided for continuous unwinding.

Abstract: A fiber transfer system for feeding fibers to the needles of a sliver high pile fabric circular knitting machine, in which the width of the fiber transfer path from the feed rolls to the needle line at the doffer is constant. Adjustable sliver entrance guides accurately direct the roving into the feed rolls and determine the location and width of the fiber transfer path. A continuous film of fibers of selected width and uniform density is transferred from the feed rolls via the main cylinder and doffer to the knitting machine needles. The main cylinder preferably is of a greater axial width than the doffer. It is covered by a narrow, elongated strip of wire-covered clothing wrapped helically around its periphery. The doffer is enveloped by straight wound card clothing, preferably constituted of a rectangular segment of wire-covered clothing having its opposite ends abutting on the doffer. The invention maximizes utilization of the fiber transfer area available to the knitting machine.

Abstract: A batting aid having a sandbag with a vertically adjustable support on its upper surface. The top of the support has a seat member with a slot in which a disc is mounted for pivotal movement about a horizontal axis. Pivoting of the disc in one direction is limited by an adjustable braking member. An inverted L-shaped rod is fastened to the top of the disc. The short arm of the rod is threadedly connected to one end of a housing, and a ball is secured to the other end of the housing. A vertically adjustable rubber stop is mounted on the sandbag in position to be hit by the long arm of the L-shaped rod when the ball is struck by a racket, bat or golf club. The rubber stop causes the disc, rod, and ball to rebound toward their original position, and the braking member completes the resetting of the ball to its original position for the next striking swing.

Abstract: A document separation device for separating documents in a stack employs counter-rotating feed drum and friction belt members to strip away and hold back more than a single document trying to pass between them. The structure employs a pair of stripper idlers mounted for free-wheeling rotation adjacent the feed drum. The stripper idlers are constructed and arranged so as to be controlled by the documents passing between them and the adjacent feed drum so as to automatically speed up or slow down when required. The stripper idlers are designed to maintain the proper force against the drum or a document passing therebetween to feed the documents in the desired path through the apparatus and to straighten out severely curled leading edges of the documents to avoid jamming, tearing or skewing of the documents. In addition, the idler strippers serve to fan out the documents to hold them in a desirable condition for ease of separation.

Abstract: The invention provides a manually held leash, lead, line or the like for large and strong animals which incorporates a shock absorbing device for diminishing the effect of the force or strain transmitted when the animal suddenly and forcibly pulls, lunges, bolts, jumps, etc. The shock absorber incorporates resilient shock absorbing means automatically operative to oppose the force exerted by the animal and to diminish its effect on the manually held leash. The device is constituted of a pneumatic cylinder the piston of which is connected to the animal and normally is retained in a retracted position by a compressive spring against which the animal pulls. In addition to the restraining force imposed by the spring on the piston, compressed air also may be utilized to absorb the shock of the animal's pulling force. The shock absorbent leash of the invention reduces the potential for injury to a person holding the leash, in the event the animal exerts a sudden and substantial force thereon.

Abstract: A fiber feeding system for feeding relatively short sliver fibers--less than one inch in length--to a sliver high pile fabric knitting machine. The system includes the usual basic elements of a carding head comprising the sliver feeding components, such as a pair of rotatable sliver feed rolls, a rotatable wire-covered doffer and a rotatable wire-covered main cylinder interposed between the sliver feeding components and the doffer. By utilizing a sliver feed plate as one of the sliver feeding components, together with one or more sliver feed rolls, the fiber pinch point may be advanced close to the periphery of the main cylinder. Where one or more pairs of sliver feed rolls are utilized without a sliver feed plate, each roll has a circumference not exceeding four times the minimum length of the sliver fibers.
