Abstract: An improved rear bow sight used in archery. The present invention is a bowstring mounted rear peep sight formed of clear, preferably acrylic, material. The transparent characteristic of the present invention allows the archer to align the rear bow sight with the forward sight pin, while remaining focused on the position on the target at which the archer is aiming. A second embodiment of the present invention includes an ambient light collecting fiber which acts as a rear transparent sight pin within a sight window. The light collecting fiber is wrapped about the sight in order to collect ambient light, while the second end of the fiber acts as the sight pin and is centrally positioned within the sight window. The sight pin provides an illumination point for alignment with a forward sight in order to set proper aim at a target.

Abstract: The invention is a highly precise sight for archery. The invention uses a C-frame that is attached to the bow by a bar. Across the open area of the C a blade is attached. The blade contains a rack and along the blade runs a gauge on the rack. For an archer to sight he moves the gauge up and down the blade which moves the sight up and down. The archer can precisely measure to one thousandths of an inch from the gauge. Thus if an archer wishes to reposition his sight to the exact location within a thousandth of an inch all that is necessary is that he write down or remember the gauge readout. In one embodiment of the invention the gauge is analog. In another embodiment of the invention the gauge is digital. The sight also has a windage adjustment that can also be adjusted down to one thousandths of an inch. To get the accuracy down to one thousandth of an inch for this elevation and still manufacture the sight inexpensively, applicant used the parts from mass produced calipers.

Each frame contains a filament that is vertical when the bow is in the shooting position and a plurality of filaments that are horizontal when the bow is in the shooting position. Each filament is located in a plane perpendicular to the plane formed by the bow and bowstring. When the bow is in the shooting position, each filament in the far frame is located in a plane passing through the corresponding filament in the near frame and the eye of the archer. The intersection of the superimposed vertical filaments with each pair of corresponding superimposed horizontal filaments defines a sight for a target of a particular distance.

The light gathering fiber is disposed in the body member at the point of intersection of the cross hairs, and may be press-fit into place. A threaded bolt, which attaches the sighting device to the archery bow, has an end that is overmolded with the body member to form an integral unit. Additional light gathering fibers may be used for different distances, with each of the fibers being substantially parallel to the archer's line of sight. The sighting device may optionally include a source of artificial light for low light conditions, or a lens that is normal to the fiber and that retains the fiber parallel with the archer's line of sight.

Abstract: A rear peep sight for use with an archery bow has a sighting body with front and rear surfaces joined by a side surface and a mounting groove formed in the side surface for retaining the sighting body on a bowstring. A sighting aperture and a plurality of locator apertures extend from the rear surface to a bottom surface of a cavity in the sighting body. An insert body in the cavity is formed of a light transmitting material for transmitting light incident at the front surface through the locator apertures to an eye of an archer located at the rear surface. The insert body is removably retained in the cavity by the bowstring such that it can be replaced by an insert body of a different color. Shutters formed on the sighting body rear surface, opaque areas on the insert body and shutter apertures are utilized to vary the amount of transmitted light reaching the eye of the archer.

Abstract: Apparatus to provide improved archery accuracy, by correcting bow handle twist problems, includes: a bar, attached to the bow handle parallel to the position of the arrow; an elastic cord, band, or tube, attached at one end to a front portion of the bar and at the other end to the bow string at a point which aligns the elastic cord with the bar when the bow is at full draw. Slight twisting of the bow handle causes a lateral movement of the rear portion of the bar relative to the elastic cord. Observation of this movement by the archer permits him to change his grip of the bow handle to eliminate the twist and thus improve accuracy. Observation of such movement of the rear portion of the bar is enhanced by placing a small plate at the rear end of the bar together with a pointer on a pivot pin. Other improvements include use of electrical contacts and lights to indicate the presence or absence of twist.

Abstract: A bowsight for attachment to a bow. The bowsight has a crosswire frame which is supported by a bracket held to the bow. A pin slide is formed in an inner frame member and has a cylindrical opening. The pins can emit light and are mounted in transparent discs which slide into the cylindrical opening and which are tightened by an Allen screw against a slot in the disc, thereby expanding the disc against the side of the pin slot. The transparent disc gathers surrounding light and transmits or directs the light to the light-emitting pin. A lens or a light-emitting source can be positioned in the cylindrical opening to surround the transparent disc with light. The crosswire frame may be incrementally moved up and down with respect to the bracket by locking a spring-loaded ball bearing in any one of a plurality of detents in the frame. The spring-loaded ball bearing may be forcibly engaged so that the spring is completely compressed thereby locking the ball bearing in a chosen detent.

Abstract: A peepsight device for mounting on the bowstring of an archery bow. The device is characterized in that it includes a skeletal ring and an interiorly-mounted transversely-extending frame. The frame demarks and defines a peepsight orifice. Zonal areas on either side of the frame delineate, in conjunction with the circumscribing skeletal ring, fields for viewing general target areas contiguous to a peep-orifice-correlated primary target. Thus, the ease of sighting and acceleration of the sighting process itself are enhanced. Wedge-like structures integrally formed with and extending rearwardly of the ring and of the frame define vertical walls against which divided strands of the bowstring bear frictionally, and open ended slots in which the traversing bowstring strands are trained and restrained.
