BOW STRINGER Filed Sept. 19, 1962 INVENTORS BRUCE. W. BROWMNG KQRL. R. LEWB United States Patent 3,207,145 BOW STRINGER Bruce W. Browning and Karl R. Lewis, Ogden, Utah, as-

signors to Browning Industries, Inc., Ogden, Utah, a corporation of Utah Filed Sept. 19, 1962, Ser. 'No. 224,627 6 Claims. (Cl. 12423) This device relates to archery bows and is more particularly directed to a bow stringing device.

With the advent of archery as an extremely popular sport participated in by men, women and children, the undertaking of stringing and unstr'inging a how has become quite a chore and problem. Many devices and techniques have been developed in order to prevent persons stringing and unstringing bo'ws of large draw weight especially from hurting themselves or from injuring the bows. However, it has been noted that these techniques are involved and had to be learned in order to be followed properly, while the devices used are bulky and difficult to handle in accordance with the instructions concerned. The danger of failing to apply the proper technique, or to follow the instructions while using the particular device in stringing and unstringing a bow, is manifold that results either from the lack of skill in the user thereof or in his failure to learn the technique properly.

Therefore, it is a principal object of the present invention to provide a bow stringer for stringing and unstringing archery bows, which device is simple in design and construction, inexpensive in cost and very readily learned by the archer in its proper use.

Another object of the present invention is to provide a bow stringer for archery bows which is extremely safe in its use by archers and that notwithstanding lack of skill of the user or failure to use the device properly, the user does not endanger himself nor the possibility of damaging the bow.

A further object of the present invention 'is to provide a device 'for stringing and unstringing an archery bo'w which is so compact that it can be carried by the user in his pocket when the bow has been strung or on the bow itself when not strung, so that it renders the device readily available for use at all times.

A still [further object of the present invention is to provide a bow stringer which renders a person capable of stringing and unstringin'g bow's of heavy draw Weights easily that heretofore required the use of two experienced archers who, during the stringing and unstringing procedure exposed themselves to possible injury and to the possibility of damaging the bow.

With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

FIGURE 1 is a perspective view of my bow stringing device.

FIGURE 2 is a fragmentary side view of a bow string retaining button.

FIGURES 3-5 inclusive are side views of the steps in the manner of using the bow stringer for stringing a bow.

FIGURE 6 is a fragmentary perspective view of bow after having been strung and prior to the removal of the bow stringer from the bow tip.

Referring to the drawing wherein like numerals are 3,207,145 Patented Sept. 21, 1965 l ce used to designate similar parts throughout the several views,.the numeral 10 referes generally to my bow stringing device which consists of a length of high strength cord 11 such as woven nylon having its ends attached to brackets 1-2 and 13. The cord 11 is of convenient length that will permit slipping the

brackets

12 and 13 over the

tips

14 and 15 and onto the

limbs

29 and 30 Without necessity of flexing the bow 16, as is explained in detail hereinafter.

The bracket 13 is a tapered rectangularly shaped sleeve having an opening substantially equal to the cross section of the limb 29 of the how 16 at preferably 3 to 4 inches from the free end of the tip 14 so that the bracket 13 will become wedged on the limb 29 at that distance from the 'free end thereof. The bracket 12 is similar in size and shape to the bracket 13 except that the former is provided with a slot 17 extending the full length of the tapered bracket 12. Both of the brackets 12 and *13 are provided with tabs 18 having openings 19 for receiving the ends of the cord .11 that are bound thereto by lashing 20. In order to prevent the

brackets

12 and 13 from injuring or marring the surface of the

limbs

29 and 30 as they slide along the limbs into position, the brackets =12 and 13 are provided with a coat of resilient plastic materi-al or covered with leather.

Threaded on the cord III is a loop retaining button 21 of cylindrical shape and having a radially disposed bore 22 through which the cord 11 is threaded. The size of the bore 22 is such that the cord 11 fits extremely tightly therein so that the button 21 can be moved along the cord 11 only when a great deal of force is applied. The button 21 is provided also with a peripheral groove 23 for receiving a loop 24 of a bow string 25, the other end having a loop 26. Adjacent the ends of the

tips

14 and 15 there are provided the conventional notches 27 for receiving the loops '24 and 26 of the bow string 25.

In the normal use of the bow stringer 10 for stringing the bow string 25 on the bow 16, the loop 26 of the bow string 25 is slipped over the end of the tip 14 of the bow 16 and made to engage the notche s 27 thereon. The bracket .13 of the bow stringer 10 is then slipped over the end of the bow tip 14 until it becomes wedged on the limb 29 as shown by FIGURE 4. The other bracket 12 is then slipped over the end of the tip 15 and made to slide along the limb 30 until it becomes wedged thereon.

A person then taken the bow 16 in his hand and holds the bow horizontally with the belly of the how 16 extend ing downwardly. He steps on the cord 11 and pulls upwardly on the how 16 as shown by FIGURE 5 to cause the how 16 to flex. The distance between the ends of the bow tips -14 and 15 becomes foreshortened permitting the loop 24 of the bow string 25 to he slipped over the end of the bow tip 15 and become engaged by the notches 27. Now the upward pull applied by the person on the bow 16 is released slowly causing the bow string 25 to become tightened on the bow 16. The cord 11 of the bow stringer 10 will now be hanging loosely on the bow 16. The bracket 12 is then slid along the bow limb 30 and as the bow string 25 passes through the slot 17 the bracket 12 is removed from the tip 15. The bracket 13 is then slipped off the tip 14 thereby removing the bow stringer 10 from the bow 16.

To remove the bow string 25 from the how 16 known as unbracing the bow, as must be done on heavy reflex bows when not in use, the procedure described hereinabove is now reversed. The

brackets

12 and 13 are slipped on the

limps

30 and 29 respectively with the cord 11 extending loosely therebetween. The how 16 is grasped while the how 16 is held horizontally with the belly of the bow extending downwardly. The person steps on the cord 11 and pulls upwardly on the bow 16 as shown by FIGURE until the bow string 25 hangs loosely on the bow 16. The loop 24 of the bow string 25 is then slipped off the bow tip 15 and then slipped over the button 21 and made to lie in the peripheral groove 23 as shown by FIGURE 4. The bow 16 is now unstrung and may be stowed away with the bow stringer and the bow string 25 attached thereto as shown. The how 16 is in its non-flexed condition with the bow stringer 10 and bow string 25 attached thereon ready for stringing the how 16 when desired. The button 21 produces the additional function of preventing the bow string 25 whose loop 24 is engaged in the groove 23 from untwisting and thereby affect its proper fistmele or bracing height. The fistmele is the distance from the bow string to the bow at time of release of the arrow when shooting same. When an archer has decided on this distance as being most desirable for him, he does not want it to vary as he strings or unstrings his bow.

It can readily be noted from the above explanation of bow stringer 10 and its application to the bow 16, that the bow stringer 10 is a compact device of simple construction and expedient in its use to string and unstring a bow. Any person can readily use the bow stringer 10 without any danger to himself or to the surface finish of the bow. Also, there is no danger of damaging the bow during the stringing or unstringing of the bow with the bow stringer 10 as the same forces are applied to the bow during this stringing operation as during the shooting of an arrow, which forces the bow is built to resist.
