' 3 Claims. (CI. 33-46) I This invention relates generally to archery equipment, and has particular reference to an improved sighting device for an archers bow.

While a relatively large number of archery sighting devices or bow sights have been developed heretofore, it has been found that the majority of them are either too complicated'or too expensive to appeal to the average archer. The; present invention, therefore, has. as its broad objective the provision of a relatively simple and inexpensive sighting device which utilizes a novel construction for obtaining the rangeadjustment and compensating for wind drift.

More specifically, it is an object of the invention to provide a sighting device having a sighting pin which can be quickly moved to any desired position of adjustment and will remain in such position without the use of set screws or'other supplemental holding means. 7 Another specific object of the invention is to provide a sighting device having a sighting pin which can be adjusted for range by simply rotating the pin, and adjusted for wind drift by. simply moving the pin lengthwise relative to its support. ;A' further specificobjpgt of the "invention is to provide a sighting device wherein rotation of the sighting pin operates to raise or lower it on a supporting strap by reason of frictional engagement of the pin with a plastic covering on the strap.

Still another specific object of the invention is to provide a sighting device having a simple yet durable construction in which relatively little wear is possible.

Other objects and advantages of the invention will become apparent from the following detailed description thereof read in conjunction with the accompanying drawings which illustrate a representative embodiment of the invention for the purpose of disclosure.

In the drawings:

FIGURE 1 is a diminutive side elevation of an archers bow having a sighting device embodying the invention mounted thereon;

FIGURE 2 is a front elevation of the sighting device;

'FIGURE 3 is a side elevation of the sighting device;

FIGURE 4 is a rear elevation of the sighting device; and

FIGURE 5 is an enlarged fragmentary longitudinal section through the device taken substantially along line 5-5 of FIGURE 2.

Referring now to the drawings, wherein like reference numbers designate the same part in each of the views, generally indicates the sighting device which is adapted to be mounted on a how 12 above the handle 14 thereof as indicated in Figure 1. To this end, the device includes an elongated, substantially rigid supporting strap 16 having offset end portions 18 which may be secured to the bow by some suitable means such as taping or lashing so that the remainder of the strap is spaced outwardly from the bow. Mounted on the outwardly spaced portion of the strap, in transversely disposed relation thereto, is a sighting pin or rod 20 having a bead 22 at one end thereof which the archer aligns with his target when shooting.

The sighting pin 20 is carried by a substantially U- shaped bracket or clip 24 having a back portion overlying one side of the strap 16 and side portions which extend beyond the other side of the strap and are provided with aligned apertures 26 in which the sighting pin is received.

The bracket is slidable in the longitudinal direction of the strap, and the sighting pin is mounted for both rotation and lengthwise sliding movement in the apertures 26.

In accordance with the invention, the sighting pin 20 is adapted to be raised and lowered on the supporting strap to adjust for the target range by simply rotating the pin. In the embodiment shown, this is accomplished by providing the outwardly spaced portion of the strap, which is preferably made of metal, with a covering 28 of a yieldable surfaced material, and providing the pin with traction means in the form of a knurled or otherwise roughened surface30, the pin preferably being made of a relatively hard material such as brass. The covering 28 may be in the form of a seamless sleeve or sheath of relatively soft plastic material which is drawn onto the strap so that it tightly engages same. The transversely disposed sighting pin is maintained in close contact with this plastic covering by a means to be presently described so that its knurled surface 30 bites into the softer plastic material and rotation of the .pin causes it to roll up or down on the strap and carry the-slidable bracket 24 with it.

t In order to maintain the sighting pin in close frictional contact with the plastic covering 28 on one side of the strap, a spring 32 is positioned between the covering on the other side of the strap and the back of the bracket. Spring 32 is formed with a double reverse curve or substantially W shape as is best shown in FIGURE 5, and its central loop 34 is flattened slightly when the bracket is pressed thereagainst to permit the sighting pin to be mounted in thealigned apertures 26 whereby the spring biases the pin into close contact with the plastic covering as stated above. The two outside loops 36 of the spring make line contact with the covering 28 and slide easily along the smooth plastic surface thereof when the bracket is moved up or down on the strap due to rotation of the sighting pin.

As previously mentioned, the sighting pin 20 is movable lengthwise relative to the bracket 24 and supporting strap so that the head 22 can be moved to the right or left to compensate for drift caused by a cross wind. This is most easily accomplished by pressing the back of the bracket in towards the strap to relieve the spring pressure holding the pin in frictional engagement with the plastic covering on the other side of the strap.

While probably obvious from the foregoing description, the operation of the sighting device is as follows: The device can be used by either a right-handed or lefthanded archer by simply mounting it on the bow so that the sighting bead 22 is located on the proper side, this merely being a matter of turning the device end for end or, if the strap is already attached to the bow, removing the sighting pin from the bracket and re-inserting it in the opposite direction. Thereafter, the archer need simply rotate the pin with his fingers to raise or lower it to the proper height for the target range and the pin will re main in the position to which it has been moved due to the frictional engagement of the knurled surface on the pin with the plastic covering. The archer can then compensate for wind drift if necessary by simply pushing on one end or the other of the pin to move it to the right or left.

As will be apparent to those familiar with the art, the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiment disclosed is therefore to be considered in all respects as illustrative rather than restrictive, the scope of the invention being indicated by the appended claims.

What is claimed is:

1. In a sighting device for an archers how: an elongated, substantially rigid strap member adapted to be 2,987,820 p g r mounted lengthwise on the bow above the handle there of, a covering of plastic material on at least one side of said strap member, a bracket member slidably mounted on said strap member, a sighting pin rotatably mounted "in said bracket member in transversely disposed relation to said strap member, said pin' being of a length greater than the width of said strap member and having a sighting head at one end thereof, said pin having means thereon for producing traction between'i-t and said plastic strap covering, and spring mean on said bracket member for holding said pin with its traction means in close engagement with said plastic covering whereby rotation of the pin operates to move it and the bracket member longitudinally of said strap member to adjust said sighting bead to the target range, said pin also being movable lengthwise in said bracket member to compensate for wind drift. 7
