The present invention provides a mechanical broadhead in which the blades slide within longitudinal channels that are formed in the ferrule. The blade is formed having a transverse boss extending from the flanks which are received in a channel formed in the ferrule. A camming surface is formed on the inward edge of the blades cooperate with a compliant member to provide controlled radial movement of the blades as they slide rearwardly within the channel on the ferrule.

Method of manufacturing a sliding blade broadhead

An endless flexible print belt or character support for a printing apparatus which includes a writing medium and a striking arrangement for applying mechanical strike pulses to the writing medium, with the print belt or character support being actuated or driven so as to advance with respect to the writing medium. According to the present invention, the print belt or character support has a plurality of elongated relatively hard type bearing segments located in a predetermined side by side relationship and in close proximity to adjacent segments, with the axis of the segments being parallel. A series of reinforcing cords extend laterally across and engage the segments to provide reinforcement therefor. An elastic bonding or encapsulating material is disposed between the segments and around the cords to lock the type bearing segments in the predetermined position. The elastic encapsulating material serves to deaden or dampen the noise generated while the printing apparatus is in operation and permits the support or belt to flex as it traverses, as an example, the pair of rotating pulleys of the apparatus. In one form, the endless flexible print belt has the segments in side by side relationship throughout 360.degree., with the reinforcing cords in tension and adapted to hold the belt on the pulleys.

A type carrier belt formed into an endless loop comprising at least one elastomeric band having a trapezoidal cross-section and a plurality of interchangeable type segments snap-fitted onto the band in a side-by-side manner. Each of the segments has a flat back surface forming the radially inner surface of the belt loop, tapered leading and trailing edge portions adapted to enable said belt loop to be rotatably driven, and an indicia-bearing outer peripheral portion. The outer portion includes at least two raised pedestal portions each having an outer surface parallel to the back surface and adapted to position an indicia thereon and a dove tail-shaped slot disposed between the pedestal portions for receivably retaining the band therein. The indicia may be adapted to form alpha-numeric characters or to act as timing marks or both types may be employed on the different pedestals if desired.
