12 Claims, 19 Drawing Figures PTENTED JUL 9 4 1 ARCHERY BOW sromr BACKGROUND OF THE INVENTION 1. Field .of the Invention This invention relates to an archery bow signt of the type having plural sighting elements normally disposed in an out position, i.e., out of the line of sighting and each movable to a sighting position, i.e., into the line of sighting, and more particularly to improvements in adjustment means for making fine adjustments in the range of each sighting element and means for releasably holding each sighting element in each of the sighting positions.

2. Description of the Prior Art As is known, a professional archer employs a good quality bow and trains himself to shoot the bow by the application of a rigid patter'nof events such that extreme accuracy may be accomplished. The professional archer will always nock an arrow at the same point of the bow string, and draw the string back such that a particular portion of the hand contacts a particular portion of the head. For example, some archers draw the string back so that the tip of the index finger touches the corner of the mouth. In this manner, the feathered end of the arrow is always at substantially the same distance from the eye and there only remains the action of elevating or lowering the head of the arrow to correspond to the range at which the target is placed. Some archers aim the bow by intuition, while professional archers employ bow sights of various types.

An accurate bow sight is shown in my US. Pat. No. 3,579,839. In my aforesaid US. Pat. No. 3,579,839, I have disclosed a multiple sighting element bow sight wherein the sighting element carriers are threadedly received on a screw device which is rotatable about its longitudinal axis. Means are provided for rotating the screw device while preventing rotation of the sighting element carriers as the screw device is rotated, whereby all of the sighting elements are moved in unison, upwardly r downwardly along the screw device. In this manner, a fine vernier adjustment of a sighting element can be effected.

The present invention provides improvements over the bow sight shown in my US. Pat. No. 3,579,839.

SUMMARY OF THE INVENTION The principal object of this invention is to provide an archery bow sight having plural sighting elements wherein each of the sighting elements can be used for more than one range.

Another object of the present invention is to provide an improved bow sight wherein each sighting element may be moved independently of the others to ascertain master and secondary range marks which are recorded on a range strip carried by the sight the sighting element being locked at a position corresponding to the master range mark.

A further object of this invention is to provide an improved bow sight having a master dial by which the sighting'elements are moved in unison, whereby a se lected sighting element can be quickly and accurately positioned at one of the secondary range marks for certain archery shots and thereafter quickly and accurately returned to the master range mark positions.

A further object of this invention is to provide an improved bow sight having resilient means for releasably holding each of the sighting elements in a sighting position and in an out position.

The present invention provides a bow sight comprising an elongated member adapted to be secured to the body of a bow above the arrow receiving area thereof and having upper and lower generally parallel flange portions. A shaft extending between the flange portion, rotatably supports plural sighting assemblies at the spaced location along the length thereof. A sighting element is secured to and movable with each of the sighting assemblies. Each of the sighting assemblies is pivotal about the shaft between a sighting position wherein the sighting element is in the line of sight of the archer, and an out position wherein the sighting element is out of the line of sight of the archer.

In accordance with the invention, the elongated member includes an elongated rib-like surface which is spaced from the periphery of the sighting assembly. The riblike surface may be provided by a second shaft extending between the flange portions and parallel with the first shaft. Each of the sighting assemblies is provided with spring means engageablewith the rib-like surface for releasably holding each of the sighting as semblies in each of the sighting and out positions. The

spring means presents a pair ofangularly spaced-apart recesses eachengageable with the rib-like surface. In one embodiment of the invention, the spring means comprises a pair of spring elements having ends which are remote fromeach other, secured to the periphery of the sighting assembly; and ends which are adjacent to each other, each of which is engageable with the riblike surface. In accordance with a further embodiment of the invention, the spring means comprises a single spring element having a central portion secured to the sighting assembly and opposite ends each engageable with the rib-like surface.

Further in accordance with the invention, the shaft comprisesa screw device supported by the flange portion for rotation about its longitudinal axis. Each of the sighting assemblies comprises a carrier body supporting a sighting element and having a central bore through which the screw device extends. Adjustment means, preferably in the form of a hub having a radial flange, is, threadedly received on the screw device and extends into the central bore of the carrier body. The adjusting means operates to move the carrier body up or down on the screw device independently of the other sighting assemblies. Means is provided for preventing disengagement of the carrier body longitudinally of the adjusting means during movementof the sightingassembly, and for locking the sighting assembly at a selected position along the length of the screw device.

Preferably, a knob is provided at one end of the elongated screw. The elongated body is provided with a springloaded ball adapted to fit into a detent provided in the screw device. The ball and detent arrangement serves to releasably hold the screw device in a fixed position. The ball and detent arrangement also provides an audible click for each complete revolution of the screw device.

Thus, it will be appreciated that in calibrating the bow sight, the adjusting means pennits each sighting element to be moved independently of the others to ascertain a' master range mark which is recorded on a range strip carried by the sight. Thereafter, the sighting element is locked in position at the master range mark. By means of the master dial, the sighting element can be moved to ascertain and record secondary range marks.

When using the present sight, the master dial is employed to move the sighting elements in unison whereby a selected sighting element can be quickly and accurately positioned at one of the secondary range marks for certain archery shots, and thereafter the sighting elements can be quickly and accurately returned to the master range marks. The audible clicks provided by the spring and ball detent arrangement also aid in quickly positioning a selected sight at one of the secondary range marks a known number of clicks being required to be heard between adjacent recorded range marks.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 illustrates a conventional bow 20 comprising a central body portion 21, a gripping portion 22 bearrow receiving area 24 for receiving an arrow 25. Extending between the bendable arms 23a, 23b is a string 26 which, when pulled away from the central body portion 21, bends the arms 23a, 23b to provide the force for propelling the arrow 25. Secured to the side of the central body portion 21 by means of a bracket 27 is the bow sight 28 of the present invention.

Referring to FIG. 2, the bracket 27 is secured to one side of the central body portion 21 (FIG. 1) by fasteners 30. An arm 29 extends from the bow sight 28 into the bracket 27. Suitable fastening means, such as a bolt 31 introduced into a selected one of the spaced threaded openings 32 of the plate 29, is provided to hold the plate 29 within the bracket 27 and to provide for adjusting the plate 29 and the bow sight 28 inwardly or outwardly for a particular bow string position. The plate 29 is detachably secured to the bow sight 28 by a fastener 33 which is introduced into a selected one of spaced openings 34 provided in an elongated member 35 forming part of the bow sight 28. In this manner, the entire bow sight 28 may be adjusted upwardly or downwardly to suit requirements of a particular bow.

The elongated member 35 is provided with upper and lower generally parallel flange portions 36, 37. A postlike member 38 (FIG. 3) extends vertically between the flange portions 36, 37 to strengthen the same and to serve as a stop member, as will be described. A shaft or screw device 39 extends vertically between the flange portions 36, 37 and is supported thereby for rotation about its longitudinal axis 40. The screw device 39 is retained in position by means of snap ring 41 engaged with the lower end thereof. A knob 42 is secured to the lower end of the screw device 39 and serves as a master dial for rotating the screw device 39 when desired.

The bow sight 28 is provided with a plurality of sighting assemblies 43, each supporting a sighting element 44. As will be described, the sighting assemblies 43 are threadedly received on the screw device 39 and are thereby rotatably supported for rotation about the longitudinal axis 40. In particular, each sighting assembly 43 is rotatable between a sighting postion S wherein the sighting element 44 is in the line of sight, schematically represented by the arrow 45, of an archer; and an out position 0 wherein the sighting element 44 is out of the line of sight 45. The bow sight 28 also is provided with cooperating means for releasably holding each of the sighting assemblies 43 in the sighting and out positions S, O. In this embodiment, the cooperating means comprise resilient means or spring elements 46, 47; and a shaft or rod 48 extending between the flange portions 36, 37 and generally parallel with the screw device 39. The rod 48 provides a rib-like surface engageable by each of the spring elements 46, 47, as will be described.

In general, each of the sighting assemblies 43 includes a carrier body 49 supporting the sighting element 44, adjusting means 50 for moving the sighting assembly 43 up or down along the screw device 39, and

provided with axially aligned threadings 59. A third shoulder 60 extends perpendicular to the shoulders 57, 53 and is provided with a threaded opening 61 adapted to receive the set screw 51. It will be observed in FIG. 7 that the set screw 51 has an unthreaded end 62 of reduced diameter.

It will be observed in FIG.- 7 that the spring elements 46, 47 have aperture d ends 63 which are remote from each other and which are adapted to be secured to the shoulders 57, 58 by fastener 64. The spring elements 46, 47 also have opposite ends 65 which are adjacent to each other and which are provided with recesses 66 adapted to engage the rod 48 (FIG. 2).

Referring to FIGS. 2 and 7, the carrier body 49 also is provided with a split clamp portion 67 which threadedly receives the sighting element 44. A fastener 68 (FIG. 7) is received in threaded opening 69to clamp the sighting element 44 in laterally adjusted position. Lateral adjustment of the sighting element 44 corrects for prevailing wind conditionsThe'split clamp portion 67 includes a sighting guide 82 which cooperates with a range strip 83 secured to the post-like member 38 (FIG. 3) in setting the sighting assemblies 43 for the desired range, as will be described.

As shown in FIG. 5, the adjusting means 50 is threadedly received on the screw device 39. The hub 52 extends into the central bore 56 of the carrier body 49. When the set screw 51 is installed, the unthreaded end portion 62 thereof extends into the circumferential recess 55. It will be observed in FIG. 5 that the overall length of the set screw 51 is such that when it is tightened down, the untlireaded end portion 62 thereof engages the confronting interior wall of the recess 55, thereby locking the adjusting means 50 to the carrier body 49. When the set screw 51 is loosened, the adjusting means may be manually rotated by means of the radial flange 54 to move the sighting assembly 43 up or down along the screw device 39. During adjustments, then, the set screw 51 serves to prevent disengagement of the carrier body 49 longitudinally of the adjusting means 50.

FIGS. 3 and 4 best illustrate the use of the spring elements 46, 47. It will be observed in FIG. 3 that when the sighting element 44 is in the sighting position S, the recess 66 of the spring element 46 engages the rod 48 to releasably hold the sighting assembly 43 in the sighting position S. The sighting assembly 43 may be rotated clockwise, as viewed in FIG. 3, into the out'position (I illustrated in FIG. 4. As the sighting assembly 43 is rotated from the sighting position S (FIG. 3) to the out position 0 (FIG. 4), the spring element 46 is disengaged from the rod 48 and thereafter the recess 66 of the spring element 47 is engaged with the rod 48.

It will be observed in FIG. 3 that the carrier body 49 presents a surface.70 engaged with a confronting surface 72 provided by the post-Iike member 38. Engagement of the surfaces 70, 72 provides a positive stop for the sighting assembly 43 in the sighting'position S. It will also be observed in FIG. 4 that the carrier body 49 presents a surface 71 which is spaced from the surface post-like member 38. Engagement of the surface 71 with the surface 73 provides a positive stop for the sighting assembly 43 when in the out position 0.

Referring to FIGS. 8 and 9, the screw device 39 is provided with an enlarged end 74 which is rotatable in a lower flange bore 75 and which is secured to the knob or master dial 42. A spring-loaded ball and detent arrangement 76 is provided for releasably holding the screw device 39 in fixed position. The ball and detent arrangement 76 includes a longitudinal groove or detent 77 provided in the enlarged end 74; and a ball 78 movable through a passageway 79 provided in the lower flange 37, into engagement with the detent 77. A spring 80 compressed between the ball 78 and a cap 81 threaded into the passageway 79, urges the ball 78 into engagement with the detent 77.

SIGHT CALIBRATION The bow sight 28 may be calibrated as follows. Beginning, for example, at a target distance of 15 yards, the

set screw 51 of the uppermost sighting assembly 43a is loosened. By alternately shooting an arrow at the target (trail shot) and by moving the sighting assembly 43a up or down by rotation of the adjusting means 50, a position for the sighting assembly 43a can be determined by which successive arrows can be placed in the bulls-eye of the target. A mark is made on the range strip 83 and labeled 15, see FIG. 2. The set screw 51 is now tightened, thereby rendering the adjusting means 50 inoperative. The just-calibrated sighting assembly 43a is termed the l5-yard sight and the 15-yard range mark on the range strip 83 is termed the master range mark for the IS-yard sight.

Short range targets, for example 20 and 25 yards, require only a slight adjustment between the settings and therefore separate sighting assemblies cannot be positioned at these yardages. Consequently, the l5-yard sight is used in determining the secondary range marks corresponding to the 20 and 25-yard ranges. The 20 yard range mark is ascertained by rotating the master dial 42 after each trial shot to lower the l5-yard sight 43a to a position by which successive arrows can be placed in the bulls-eye. That position is marked on the range strip 83 and is labeled 20, i.e., 20 yards, see FIG. 2. This process is repeated, utilizing the master dial 42, for the 25-yard mark. Knowledge of the number of audible clicks produced by the spring and ball arrangement 76 (FIGS. 8 and 9) between range marks aids the archer in accurately dialing to the axact setting every time. The IS-yard sight 43a is now returned to the master range mark, i.e., l5-yard mark.

To secure the next sighting assembly 43b at a desired yardage, the set screw 51 thereof is loosened, the sighting assembly 43a is positioned by the trial-and-error method described above utilizing the adjusting means 50 thereof. The set screw 51 is then tightened. The secondary yardages are determined utilizing the master dial 42 as described above.

It should be readily apparent that the master dial 42 and the screw device 39 secured thereto, serve as a range compensator by which the sighting elements are quickly and accurately moved between the master and secondary range marks. Moreover, additional extremely fine adjustments, if necessary, in the sighting elements can be made by slight rotation of the master dial 42.

FIG. 10 illustrates another embodiment of the invention wherein the resilient means comprises a single spring element 84 having an apertured central portion 85 adapted to be secured to the shoulder 60 of the carrier body 49 by the fastener 64. The spring element 84 presents opposite profiled ends 86, 87 each provided with one of the recesses 66. FIGS. 11 and 12 illustrate sighting assemblies 43' incorporating the spring element 84 of FIG. 10. When the sighting assembly 43' is in the sighting position S (FIG. 11) the recess 66 of the arm 86 is engaged with the rod 48. When the sighting assembly 43' is in the out position (FIG. 12) the recess 66 of the opposite arm 87 is engaged with the rod 48. In this embodiment, the connecting means function described above is performed by the set screw 51 which is received by the threaded opening 61 (FIGv FIGS. 13 and 14 illustrate a further adjustment feature of the present bow sight, which comprises auxiliary dial means 109 for effecting rapid rotation of the screw device 39 thereby to move the sighting elements up or down along the screw device 39 in a rapid manner. The auxiliary dial means 109 comprises a first gear means 110 freely rotatable about a portion of the rod 48 which extends above the upper flange portion 36 and is retained thereon by a snap ring 111. The first gear means 110 may be manually rotated by a knob 112 which may be formed integrally therewith. A second gear means 113 is received on a portion of the screw device 39 which extends above the upper flange portion 36. The second gear means 113 and the screw device 39 present confronting flat surfaces 114, 115, respectively, which non-rotatably connect the second gear means 113 to the screw device 39. In the preferred arrangement, the diameter of the first gear means 110 is two to four times greater than that of the second gear means 113. The first gear means 110 is freely rotatable about a longitudinal axis 117 (FIG. 14) of the rod 48 the axis 117 being parallel with but spaced apart from the longitudinal axis 40 of the screw device 39. The auxiliary dial 109 may be incorporated in the bow sight 28 of FIG. I.

With reference now to FIG. 15, another embodiment of the invention is shown wherein a bow sight 88 is provided with a single sighting assembly 89. Adjusting means 90 is provided by which the sighting assembly 89 may be moved upwardly and downwardly along the elongated member 35 indpendently of the screw device 39. The adjusting means 90 is accessible for use regardless of whether the sighting assembly is in the out position 0 (FIG. 16) or in the sighting position S (FIG. 17).

Referring to FIG. 18, the sighting assembly 89 includes a carrier body 49 having a central bore 56 which receives journal means such as a centrally apertured bushing 91. The bushing 91 may be formed from nylon so that it is freely slideable along the screw device 39.

The adjusting means 90 comprises a C-shaped member 92 having upper and lower arms 93, 94 positioned above and below the carrier body 49, and a web 95 connecting corresponding ends of the arms 92, 93. As best shown in FIG. 19, each of the slots 96 presents a semicircular end 97 provided with partial threads 98, and an opposite plain end 99. The partial threads 98 are provided along an arc length indicated at 100 the arc length 100 being long enough to provide effective thread engagement between the partial threads 98 and the threads of the screw device 39.

Referring to FIGS. 18 and 19, the adjusting means also is provided with resilient means 101 for urging the partial threads 98 into threaded engagement with the screw device 39. The resilient means 101 may comprise a spring element having an apertured central portion 102 and oppositely extending arms 103. The apertured central portion 102 is engaged with a boss 104 formed in the web 94 of the C-shaped member 92. The boss 104 has a threaded bore 105 receiving a guide member 106. The guide member 106 presents a forward threaded end 107 extending into a passageway 108 provided in the carrier body 49.

As best shown in FIG. 18, the resilient means 101 urges the C-shaped member 92 in a direction such that the partial threads 98 of both arms 92, 93 are engaged with the screw device 39. Thus positioned, the sighting assembly 89 may be moved upwardly or downwardly along the screw device 39 by rotation of the master dial 42 (FIG. 15). However, when it is desired to rapidly move the sighting assembly 89 from the position illustrated in FIG. 15 to a second position remote therefrom, the archer need only depress the C-shaped member to the position illustrated in FIG. 19 wherein the partial threads 98 of both arms 92, 93 are disengaged from the screw device 39. The sighting assembly 89 now may be moved upwardly or downwardly, sliding on the bushing 91, to the new desired position. Thereafter, the C-shaped member is released whereby the partial threads are re-engaged with the screw device 39. The master dial 42 may then be employed for fine adjustment of the sighting assembly 89 at its new position. The auxiliary dial means 109 (FIG. 15) also may be s y rapidly inoxinsfltqsishtigs asse bly 9 between known sighting positions.

It can be seen, therefore, that the present invention provides several adjustment features operating in concert to provide a versatile bow sight. Certain of the plural sighting elements may be quickly and accurately calibrated for master and secondary ranges. The present invention also provides for the synchronous movement of all the sighting assemblies between master and secondary ranges without affecting the range adjustment of the individual sighting assemblies; and for rapid movement of one or plural sighting elements between known sighting positions. Improved means for holding each of the sighting assemblies in the sighting and out positions also is provided. Although the invention has been shown in connection with certain specific embodiments, it will be readily apparent to those skilled in the art that various changes in form and arrangement of parts may be made to suit requirements without departing from the spirit and scope of the invention.
