Patented Feb. 16, 1954 UNITED ASTATES PATENTMoFFicE ARCHERY SIGHT John F. Pizzuti, Hamtramck, Mich.
Application November 29, 1951, Serial No. 258,900
This invention relates to sights for use in connection withl the aiming of arrows when shot from a bow either in target shooting or in hunting; and has for its object to provide means of a nature particularly adapted to facilitate the setting of a sighting point to meer, the peculiar requirements of any particular marksman to suit his own manner of shooting and the type of bow or arrows' which he is in the habit of using.
' The general and variousV methods of sighting involving, for instance', point of aim and point of loose, are well known to those familiar with this art and will not be discussed at length hereinit being thought suflicient to mention that any mechanical sight should be capable of being set or coordinated not only with the actual target distances but with the aiming habits of the archer.
Furthermore, as the limbs of the bow are movable by flexion relative to the handle, it is highly desirable that any sight be free of any influence by such movement of the proximate bow limb, so that it is an important object of the present invention to provide a sight which is mounted solely upon the rigid handle and is free of disturbing influence of any flexible part ofthe bow.
A further yobject of the invention is to provide a sighting point or button which is adjustable to and between upper and lower positions about a single fixed location point, which location point, in turn, is rigidly maintained in a iixed position relative to the handle of the bow and independently 'of either limb of the bow.
Still further, the said invention is characterized by the provision of a sight arm, swingable vertically and forwardly of the bow on a pivot which isfflxedly carried by the handle of the bow and which is free of any infiuence by the exing movement of the limbs of the said bow.
f The invention still further contemplates the provision of a flat plate firmly secured at its lower end portion to the rigid handle of the bow and freely spaced from the upper flexible limb of the bow, said plate lying in a true plane extending through both the bow and the bow string, a sight arm being pivoted on said plate and swingable in a vertical plane over the face of the plate whereby calibrations determined by trial by the archer may be marked on the plate for future reference, a laterally adjustable sighting point or button being carried by the outer end portion of said arm.
Still further objects or advantages additional or subsidiary to the aforesaid objects, or resulting from the construction or operation of the invention as it may be carried into effect, will be- 3 Claims. (Cl. 33-46) 2 come apparent as the said invention is' hereinafter further disclosed.
In carrying the said invention inte e'ect, I may adopt the novel construction and arrangement of parts hereinafter described, by way of example, having reference to the accompanying drawing, wherein:
Figure l is a side elevation of part of an archery bow showing the adjustable sight of the present invention attached thereto; and
Figure 2 is a top plan view of the said sight, with the plate thereof shown in cross section taken on a planeindicated by the line 2 2A in Figure l.
Similar characters of reference indicate similar parts in both figures` of the drawing.
The handle element I 0 of the bow is shown as being equipped with the usual arrow rest I I, and the said handle has extending from its upper end the iiexible limb I2 as in a steel bow. In an allwood bow the limbs may be integral with the handle, but it is intended that the feature of mounting ythe sight so that it is free of any flexible portion or limb of the bow is intended to be maintained regardless of the particular type of bow to which the sight may be applied. I3 is a flat plate, or semi-circular form in outline, provided with a stud or pivot I4 at the center offits curved outline and further provided at its lowerend with laterally extending lugs I5 for attachment to the upper end portion of the handle I0, as by means of screws I6, although the actual manner of attachment is one of choice or convenience as will be well understood.
Care should, however, be exercised in attaching the plate to the handle in order to ensure that the said plate will lie in a true plane extending through both the bow and the bow string (not shown) in order that a sight arm I1, which is swingably mounted on the said pivot I4, may be adjusted truly in the same plane in which the bow is drawn in shooting. Where the type of mounting shown is used, the face of the upper end of the handle Imay be squarely recessed to provide a at surface at I8 and a locating shoulder I 9 to determine the correct positioning of the said plate I3 on the bow.
The plate I3 has formed therein an arcuate slot 20 through which a stud 2| carried by the arm II and provided with a lock nut 22 extends; and the said arm is further provided with an indicatr 23 to ride the semi-circular periphery of the p a e.
Toward the outer end of the said arm I1 are shown as an example, two holes 24 and 25 in 3 either of which may be secured a cross pin 2B. which pin is threaded for adjustment as to the extent which the point or button 21 may DI'OJ'eCi? laterally of the general plane of the sight. The purposes of this adjustment to meet lateral variations of arrow flight due to wind, type of arrow being used or other factors will be readily recognized by those familiar with archery and therefore, will not be discussed in detail herein.
It will 'be seen the arm ali @i this sieht may be of any convenient length, and that-*the actual lineal sweep of the adjustment at the arcuate slot 20 is greatly multiplied at the pin 2,6, due to the Adifference of radius. in radii may be varied, if desired, by simply moving the said pin to a hole closer t@ or .fuimer from the pivot I4.
This diligence By whatever mechanical means 'the lvariation of the radius of the arc of movement ofgfthe pin 26 is accomplished, it perjmits the user to not only vary the Osier-.eil range cf @desiring .eisiitiiia to increase or decrease the agitent of .actua adiustmerit required ,per .0f .,ual'dage: and .this variati-dn fir-bril .finer to .waneer i adi-deinem will diner-ent archerslhe Y.fici/.ice described .may .be --Qf Mery rdbuei construction without loss of'easeangl,sin-@.Ohe in the ,Swinging adjustment of siehtlarni H, .and the sight AIJ may .bevreadilv andiirmly locked in positions ,oi ,edJiSimeni Witheet diriger i df disturbing theadiiiimenb .in-.deine 5o.
