SIGHTING ELEMENT FOR BOW FOR ARCHERY Filed March 7. 1966 INVENTOKS AZ/EUST E RDLUF'F y NINA s. IPUL arr United States Patent 3,389,695 SIGHTING ELEMENT FOR BOW FOR ARCHERY August F. R0106 and Mina S. Roloif, both of RD. 1, Box 182H, Morganviile, NJ. 07751 Filed Mar. 7, 1966, Ser. No. 532,208 2 Claims. (Cl. 124-24) This invention relates to the art of archery and in particular to an improved sighting device for the bow.

The prior art discloses other bow sights in which the bow sight is mounted in the so called bow window and in which the sill of the bow is provided with a cavity to receive the sight device. To bore, cut or form a cavity or recess in the sill of the bow at approximately the center of its bending stress is to reduce the potential bending strength and likely to produce the weakest point in the bow. In some of these prior art devices, the bow sight is not a permanently mounted sight, but rather is a removable sight that must be mounted and adjusted each time the bow is used.

It is an object of this invention to provide a bow sight that is attached to the sill of the bow without impairing its strength.

A further object of this invention is to provide a permanently mounted sight on the sill of a bow.

A still further object of this invention is to provide a bow sight that may be set in one position with relation to the bow but permits a sighting based upon the size or power of bow utilized.

A still further object of this invention is to provide a permanently mounted sight for a bow in which the sight is provided with two windows to assist the archer in sighting based upon the individual.

A still further object of this invention is to provide a permanently mounted sight for a bow in which the sight is provided with two windows and to marks for fast sightmg.

Other objects of this invention may be apparent by reference to the accompanying detailed descriptions and the drawings in which:

FIG. 1 illustrates a side elevational view of the bow and arrow slightly in perspective;

FIG. 2 is an enlarged detail of the sill and the bow with the sighting device;

FIG. 3 is a side elevational view of the sighting device taken on line 33 of FIG. 2;

FIG. 4 is an elevational view of the sighting device taken on line 4-4 of FIG. 3;

FIG. 5 is a plan view of the string sight taken on line 5-5 of FIG. 1.

Referring to the drawings and particularly to FIG. 1, there is illustrated a bow 10. The bow is provided with a handle portion 11 adjacent to the central position or sill 14. The sill 14 extends the length of the sighting area 12 and is bounded on the upper side by a slanted portion 15 and on the lower side by an arrow rest shelf 16. The string 17 extends from one end of the bow 18 to the opposite end of the bow 19 and is attached at each end. The string is pulled taut in mounting upon the bow to be ready for operation. To assist the archer in positioning his arrow with relation to the string there are provided an upper nocklock 9 and a lower nocklock 8. They are separated just enough to permit the end of the arrow to abut with the string and permit the archer to grip the arrow between these two guides. A sighting device 20, FIG. 2 is provided and is mounted upon the sill 14 of the bow 10. That is, the sighting device 20 is provided with a pair of half round ends 21-22 and utilized to secure the sighting device by means of a pair of screws in the position as illustrated in FIG. 2. The sighting device comprises a length of heavy wire or round stock 24, bent in the configuration as illustrations in FIGS. 3 and 4. That is, the ends, 21, 22

3,339,695 Patented June 25, 1958 are half round simply to provide a means of securing the sighting device and with a rectangular portion for the sighting device, this permits easy removal when desired, without completely removing the screws attached and retaining same. The wire of half round stock 24 is bent as shown in FIGS. 2 and 3 so that a rectangular shaped central box 25 is formed. To provide the rectangular form a piece of additional wire or round stock 26 is brazed to wire 25 at

points

27 and 28. Also a horizontal bar 29 extends from wire 25 at about its center and is brazed to bar 26 at about its center 30. The sitghting device 20, FIG. 2 is mounted to the sill 14 so that the top of the rectangular formation is approximately 3 /2" above the arrow shelf 16, thus positioning the sight at a proper sighting position. There is also provided a sighting element in the form of a small circular rubber grommet 35 FIG. 5. The grommet having a circular aperture 26. The grommet 35 is mounted on string 17 so that the top of the grommet is 3 /2" above the upper surface of the lower nocklock 8. In utilizing the grommet 35 and sighting through the sighting device 20 the archer must grasp the bow in the left hand, by handle 11 (with a right handed archer, grasping the arrow 37 at its end while fitted to abut with string 17 between nocklocks 8 and 9. The archer must then draw the arrow and string to the desired degree of pull for that particular bow, holding the hand near the mouth so that the archers eye will be over the top of the rubber grommet 35 on the string 17 and the archer may then sight over the top of grommet 35 through the sighting device 20. The choice of the sight on the sighting device will vary, with a medium bow and with an archer who pulls the bow string correctly, his sighting should be just under the top of the rectangular bar and just within the rectangle to the left of bar 26 in the area indicated by a dotted circle. However, if the archer is using a stronger bow such as the 45# bow, his aim will be either directly on the top bar or slightly above the indicated dotted circle to provide an accurate shot. The archer will find after a number of practice shots that the exact spot on the sight 20 may be slightly varied until he has located and selected the exact spot for him or her as the case may be. The reason for slight variance in the selection of the exact point of sighting with this sighting device is because of many variations found with a bow, as no two bows are identical. There are slight variations due to the pull, the actual velocity delivered to the arrow and the habits or idiosyncracies of the archer.

It is easily understood that a sighting device on a gun may be set for that gun and remains the same for everyone due to the fact that the bullet receives its velocity from the charge and the charge is the same no matter who pulls the trigger, thus it is easy to provide an exact sighting, whereas with a bow, the bows differ, that is, they are different weight bows and they deliver difierent velocities to the arrows. The archers have habits or idiosyncrasies that differ and thus every sight is not perfectly set for a particular point but rather is set to permit the archer to select the particular point after a number of trial shots. A further feature of the sighting device 20 is the coloration, that is, the sighting device may be painted black and be provided with two bars W and W on bar 26. This is to assist optically, that is, in a quick shot the two white bars are quickly distinguished and the sight may be quickly controlled.

The shape of the sighting device may seem to cover a greater area than is necessary, however, this is not true as with a child or archer whose pull is Weak the sighting may drop down into the lower portion of the rectangle or even into the lower square depending upon the archer.

It is to be noted that the sighting device 20 takes a particular configuration. This configuration is chosen as providing a good horizontal reference as well as a good vertical reference in aiming the arrow. Other configurations may be utilized but the horizontal and vertical references is of the utmost importance. It is also to be noted that the sighting device may be strapped on, taped on the sill 14 if so desired, instead of being afiixed by screws. It is also to be noted that the setting of the sighting device and the setting of the grommet 35 will show a similar dimension. This may be varied slightly for some archers but, in any event, both of the elements, that is the top of the sighting device and the top of grommet 35 must be similarly set. Other changes may be made to the bow, that is, the handle may be changed, the shape of the bow may be different as long as the sighting device and the grommet are aligned for aiming without departing from the spirit of the invention and this invention shall be limited only by the appended claims.

What is claimed is:

1. In combination with an archery bow and string having a handle portion, a sighting portion above the handle portion, an arrow guide shelf, horizontally positioned, between the handle portion and the sighting portion, a sill vertically positioned within the sighting portion and rising from the arrow guide shelf, a sighting device permanently mounted to said sill and a sighting grommet atfixed to said string, said sighting device comprised of a wire formed with two ends bent to lay against said sill for attachment to said sill, said wire formed to extend at a right angle to said sill and form two joined squares, to provide three horizontal bars and two vertical bars as sighting references, said sighting device positioned on said sill at a predetermined distance above said arrow guide shelf and said sighting grommet positioned on said string at the same predetermined distance above the point on said string that is in alignment with said arrow shelf.

2. In a device according to claim 1 in which one of the vertical bars of said sighting device is provided with two bands of white while the device is otherwise totally black to provide a pair of optical references for fast aiming and shooting.
