Abstract:
Disclosed is an archery bowstring release that increases the power and length of the draw by having the pincer of the release being recessed a few inches behind the trigger of the release in relation to the bowstring. The present release achieves this result by having a long trigger column rigidly joined to a short pincer column at an acute angle of 20 degrees. A standard type wrist strap is preferably always used in the operation of this release.

Description:
BACKGROUND OF THE INVENTION 
   This invention falls into the general category of being a tool for archery and into the specific category of being a tool for the precision mechanical release of archery bowstrings. 
   In traditional archery, an archer will grip his bow by a handle midway along the spine of a bow and hold the bow at full arm&#39;s length with one arm. With an arrow in position and notched on the bowstring, the archer will pull the bowstring back with the other arm as far as he is able to pull it while holding on to the taught bowstring with three fingers while aiming the bow and then releasing the bowstring with the said three fingers. This is ancient art in the field of archery. 
   However, in the field of modern archery, there have been developed several devices to improve various aspects of this field&#39;s practice. Perhaps the largest development has been the invention of the compound bow. However, another significant development has been the invention of the mechanical bowstring release. The mechanical bowstring release assures a smooth and precision release of the bowstring that is impossible to match with the use of human fingers. 
   The typical bowstring release in the prior art is comprised of a single column of cylindrical or rectangular cross section that contains one or two jaws for holding a bowstring taught when the jaw or jaws are closed and also a trigger for opening the jaws to release the bowstring. The release will sometimes also possess a solid attached handle to be grasped by the archer&#39;s palm and fingers, the said handle being attached collinearly or perpendicularly to the column. More often, however, the single column bowstring release will have an attached flexible wrist strap that that the archer has around his wrist as he grips the single column body of the release. A typical archery bowstring release and attached wrist strap are shown, for example, in U.S. Pat. No. 5,595,167 to Scott. 
   The problem with all prior art bowstring releases is that the release trigger is always situated behind the release jaw or jaws. This fact means that the final position of the bowstring right before release will always be a bit less than the position of the archer&#39;s fingers in terms of the draw length of the drawn bow. 
   It would be advantageous to possess a bowstring release in which the release jaws are behind the release trigger because that much distance would be added to the bowstring draw for the same position of the archer&#39;s hand instead of subtracted from the bowstring draw that occurs when the release jaws are in front of the release trigger. This is so for two reasons. The longer the draw is, the more force there will be behind the shot of the arrow. Also, the arm drawing the bowstring has more muscle power in the middle part of the draw when the drawing hand is in front of the archer&#39;s chest than when the drawing hand is at the end of the draw when the drawing hand is at the side of the archer&#39;s chest. 
   The problem in designing a bowstring release in which the jaws are behind the release trigger is how to place the jaws in relation to the trigger so that the released bowstring will not hit the trigger or the archer&#39;s fingers. 
   BRIEF SUMMARY OF THE INVENTION 
   The archery bowstring release presented here is essentially comprised of a long trigger column rigidly fixed to a short pincer column at an acute angle (that is, an angle less than 90 degrees). This configuration of the release results in the pincer jaws being a few inches behind the trigger in relation to the bowstring. Normally, the jaws of the pincer are closed. However, when the trigger is pressed, a rod in the trigger column is depressed which rod then depresses a plate-rod in the pincer column, such second rod moving away from the pincer feet so as to allow a spring to open the jaws of the pincer. This archery bowstring release is used with a wrist strap to help the archer&#39;s hand to grip the trigger column of the release.

   DETAILED DESCRIPTION OF THE INVENTION 
   Looking at  FIGS. 1-6  simultaneously, it is seen that this archery bowstring release  9  is comprised of a long trigger column  11  rigidly fixed to a short pincer column  23  at an acute angle, that is, an angle less than ninety degrees. The column  11  and the column  23  are rigidly fixed together by welding at the seam  13  between the two columns. The inventor has found that in the best mode of this invention, the angle between the two columns is 20 degrees. The two columns  11  and  23  can be columns of rectangular cross section or columns of oval or round cross section. The inventor has found that columns of round cross section, that is, cylindrical columns are the preferred mode of construction of this invention although the inventor has also constructed this invention using square cross section columns. The bowstring release  9  is preferably made of all metal parts. 
   Running through the axis of the long column  11  is a hole  46 . Inside this hole  46  fits a movable rod  43 . Also in the column  11  is a slot  45  in which the trigger  31  is held by pinion  29  fitting tightly into a thin hole  70  in the column  11 . The pivot angle of the trigger  31  within the slot  45  of the column is lessoned by an adjustable threaded bolt  30  which screws into a threaded hole  62  of the column  11 . 
   The short pincer column  23  holds two pincers  28  and  26 . These two pincers are held in a slot  86  in the column  23  by two rods  12  and  24  that extend through two holes  87  and  88  in the slot  86  in the column  23 . The two pincers  26  and  28  can pivot about the two rods  24  and  12 . In addition the two pincers  28  and  26  also pivot about a ball bearing  51  which sits within two hemispheric holes  80  and  90 , one each in each pincer. Each pincer foot  47  and  50  has slot (see slot  89 ) that holds a roller wheel  48  and  35  that is held in the pincer foot  47  and  50  by an axle  82  and  90 , respectively. Each pincer  28  and  26  also has a hole  54  and  52  into both of which fits a small spring  53 , that normally pushes against the jaws of the pincers so as to open them if the pincers are not otherwise restrained. 
   However, the pincers  28  and  26  are so restrained from opening by a rod  36  which is pressed up between the feet  47  and  50  of the pincers. This rod  36  passes between the two roller balls  48  and  35  and on through a rectangular plate  42  to which such rod  36  is rigidly attached and which can be referred to as a rod-in-plate  91 . The rod-in-plate  91  is normally kept pressed against the feet  47  and  50  of the pincers by a large spring  41  through which extends the rod  36  and which spring sits in a slot  85  in the short column  23  and a short well  92 . Running along the axis of column  23  is a hole  49  in which the rod  36  movers back and forth when the trigger  31  in the long column is pressed. This trigger  31  presses down the rod  43  which presses backward the plate  42  which moves back the rod  36  from the feet  47  and  50  of the pincers  28  and  26  which pincers then pivot so as to open their jaws which then release the bowstring from the space  25  between the jaws of the pincers. Thus, when no pressure is exerted on the trigger  31  the pincers  28  and  26  stay closed, but when the trigger  31  is pressed back, the pincers  28  and  26  stay open. 
   The present inventor always uses this release  9  is with a wrist strap  10 . For the purpose of attaching the wrist strap  10  to the release  9 , the short column  23  has a slot  83  in which a squared off U shaped beam  20  is placed and secured to the column  23  with a hex bolt  21  which has a hex well  37 . The wrist strap  10  has two loops  7  and  8  made by the sewing seams  19  and  38  respectively. The two arms  22  and  40  of the U beam  20  are placed respectively into the loops  7  and  8  to attach the wrist strap  10  to the release  9 . The strap  18  of the wrist strap  10  has loop  6  made by the sewing seam  17  through which is attached a loop ring  16 . Through the other side of the loop ring  16  is placed a Velcro “hook” strap  15  which adheres to a “loop” strap on the other side of the wrist strap  10 . The wrist strap can be tightened or loosened by adjusting the length of “hook” strap  15  that is pulled through loop ring  16 . The wrist strap also has an extra inner layer of strap  14  for cushioning on the wrist during operation of the combination release  9  and wrist strap  10 . There are a number of ways of attaching a wrist strap to an archery bowstring release which are well known in the art. The method of attachment explained above is simply one example preferred by the inventor. 
   The combination release  9  and wrist strap  10  are operated by the archer placing his hand through the wrist strap  10 , placing the release  9  on the back of his hand between his thumb and index finger, or on the palm side of his hand, and adjusting it for preferred tightness The archer then places his index finger of that hand on the trigger  31  and presses the trigger backward toward his wrist. The pincer jaws open. The bowstring or its release loop is then placed in the space  25  between the jaws. The trigger  31  is then releases closing the pincer jaws around the bowstring or its notch loop. The bowstring is then drawn back by the archer. The archer aims his bow at the target. Then the archer presses the trigger backward. The pincer jaws open up, and the released bowstring quickly propels the arrow to its target.
