Abstract: The invention is a method and apparatus for correcting the natural nock travel of a compound bow. The bow has a cable guard rod attached to a riser supporting a cable slide at an angle to the nock travel path. The rod has a distal portion attached to the riser, a central portion angled upward relative to the distal portion, and, a proximal portion angled downward so as to form an exterior angle falling within the range of 25-40° between the proximal and distal portions of the cable guard rod. The bow has a cam mounted on an upper limb, a cam mounted on a lower limb, and two cables which are connected to the first cam, pass through the cable slide, and are connected to the second cam. There is also a bow string connected between the cams which can be drawn rearward then released to provide energy.

Each sorting bin further includes a stacking belt assembly spaced away from the drive nip and having a first end positioned at an acute angle relative to the drive nip and second end positioned adjacent a registration wall.

Abstract: This invention provides utilizes a centering device located in the accumulation portion of mail production equipment to reduce jamming caused by the insertion of material into an open envelope. The apparatus of this invention is located in the accumulation area of production mail equipment before the inserter. The apparatus of this invention includes: two guides; a solenoid and a flexible wire cable. Two centering guides are actuated through a solenoid and move to a predetermined center position to align and deskew the accumulated enclosure contents (which may include printed and pre-printed folded sheets, business reply envelopes and other insert material). A flexible wire cable is used to provide highly efficient transfer of motion from the solenoid to the centering guides.

Abstract: An envelope ejecting apparatus is disclosed for use in an inserting machine in which envelopes are fed successively in one direction along a feed path to a first location and then are moved incrementally in a reverse direction to an insert receiving position at which envelope throat opening devices open the throats of the envelopes so that insert material can be fed thereinto. The envelope ejecting apparatus is connected to the throat opening devices for operation therewith and also to the means for feeding the envelopes in the reverse direction, and there is a control means operatively interconnected between the envelope throat opening means and the envelope ejecting means for preventing the envelope ejecting means from ejecting the envelope until it is positioned at the insert receiving position and insert material has been inserted thereinto.

Abstract: The sheet feeder includes a tray having a pusher mechanism mounted at a rear portion and a feeder mechanism mounted at a forward portion. The pusher mechanism is driven through a spring wrap clutch which includes a ratchet which engages a pawl mounted on the feeder mechanism. When the feeder mechanism is in a first position the pawl is disengaged from the ratchet and the clutch is free to rotate and engage the pusher mechanism which advances the stack of sheets against the feeder mechanism, driving the feeder mechanism back to a second position where the pawl engages the ratchet, disengaging the spring wrap clutch and halting the pusher mechanism. As sheets are fed from the stack a spring urges the feeder mechanism back towards the first position, disengaging the ratchet and engaging the clutch and repeating the cycle. A spring maintains a substantially constant normal force between the feeder mechanism and the stack as the feeder mechanism moves between the first and second positions.

Abstract: In an envelope stacker, a normal force roller mechanism drives a mail piece vertically then retracts without adding significant torque to the stacker. The normal force roller mechanism is comprised of a frame and a bracket pivotally mounted to the frame, the bracket further having an aperture and an arm with a shaft extending therefrom. An idler roller is mounted to the shaft. A hub having a slot is rotatably mounted to a plate. An assembly is provided for moving the plate in a substantially horizontal direction. A generally L-shaped pin having a first end portion and a second end portion extends through the slot so that the first end portion engages the aperture of the bracket. A spring is mounted onto the L-shaped pin between the second end portion and the hub.

Abstract: An apparatus for properly positioning envelopes in an envelope inserting machine for receiving insert material is disclosed in which the envelope positioning apparatus feeds a first envelope along a prescribed feed path to a predetermined location which is beyond the normal location at which the throat of the envelope can be opened so that the envelope can receive a package of insert material, and then feeds the envelope in a reverse direction until a throat opening device is effective to open the throat of the first envelope.

Abstract: An apparatus and method for centering and aligning sheets. The apparatus includes a D-roller assembly for cyclically engaging and transporting sheets and a centering and aligning mechanism for centering the lining sheets which is synchronized with the operation of the D-roller assembly so that the centering and aligning mechanism acts upon the sheets before the sheets are engaged by the D-roller assembly. The centering and aligning mechanism includes a pair of elements extending parallel to, and symmetrically from the center-line of, the path followed by the sheets and the elements cycle from first positions inward to second positions separated by approximately the width of the sheets so that sheets positioned between the elements are centered a aligned. Movement of the elements is synchronized with the D-roller assembly by a pair of complementary oppositely faced barrel cams mounted on a common shaft with the D-roller assembly.

Abstract: The present invention provides an improvement for a document feeder comprising a feed deck, a separator assembly for separating and feeding individual documents, the separator assembly including a separator wheel disposed above the feed deck, drive structure for driving the separator wheel, and structure for adjustably positioning the separator wheel assembly to a position relative to the feed deck commensurate with the material being fed. The improvement comprises structure for pivotally coupling the document feeder to vertical frame members. The coupling structure is located at one end of the document feeder near the separator assembly. There are a pair of leg members extending below the feed deck, each of the leg members resting on a horizontal frame member at opposite sides of the document feed path. The leg members are laterally spaced so as not to interfere with documents being conveyed by the underlying document transport.

Abstract: A corner buckle feeder has a singulation roller and feed roller for initially separating and feeding glossy paper. The front corners of a sheet stack are unsupported in order to minimize the intersheet frictional forces that are influenced by temperature and humidity. The axis of the singulation roller is disposed at an angle with respect to an edge adjacent to the lead edge of the top sheet. The singulation roller drives the adjacent edge inward and the top sheet deforms along the leading edge to form a buckle.
