ARROW REST
Abstract
The shaft of an arrow is supported in the sight window of an
archery bow by an arrow rest comprising a flexible finger which
shifts laterally as it is engaged by the feathers of the arrow
after release. The finger is attached to a bendable spacer tab and
is movable therewith to a position desired by the archer where the
shaft of the arrow is aligned with the path of the bowstring. The
tab is formed of sufficiently heavy plate stock to be rigid and
remain in the desired position under lateral force that may be
applied thereto as the arrow is shot.

Description
This invention relates to improvements in arrow rests for archery
bows.
An important object of the present invention is to provide an arrow
rest which is adapted to bows of various designs and which may be
easily and rapidly adjusted to a position wherein the shaft of the
arrow is aligned with the path of the bowstring.
Another important object of the invention is to provide an arrow
rest which minimizes the contact between the feathers of the arrow
and the bow or the rest itself, in order to prevent deflection of
the arrow in its initial flight as the feathers pass the bow, and
also prevent the feathers from becoming damaged.
Still another important object of the invention is to provide an
arrow rest as aforesaid in the form of a universal attachment
suitable for bows of various designs, and which may be easily
secured to a bow without the need for a special mounting.
In the drawing:
FIG. 1 is a side elevational view of the handle section of an
archery bow, showing the arrow supporting device of the present
invention attached thereto;
FIG. 2 is an enlarged, fragmentary, front view of the structure
shown in FIG. 1;
FIG. 3 is a further enlarged, cross-sectional view taken along line
3--3 of FIG. 1;
FIG. 4 is a view of the arrow supporting device similar to FIG. 3,
illustrating the flexing of the rest;
FIG. 5 is a cross-sectional view taken along line 5--5 of FIG. 2;
and
FIG. 6 is a perspective view of the device showing the backing
partially removed from the adhesive strip.
Referring to the figures, the handle section 10 of an archery bow
is shown particularly in FIGS. 1-3, where it may be seen that the
section 10 is provided with the usual arrow shelf 12 which forms a
part of the sight window 14 of the bow. A bow for right-handed
shooters is depicted, thus the arrow side 16 is the left side of
the bow as the latter would be viewed from the rear during
shooting. The shaft 18 of an arrow is illustrated in broken lines
in FIGS. 2 and 3 in the position assumed at full draw. Note in this
respect that the head 20 of the arrow (FIG. 3) is in approximate
lateral alignment with the front of the bow.
The arrow supporting device of the present invention includes a
support plate 22 having a line of bend 24, the plate 22 presenting
a pair of leaves 26 and 28 joined at the line of bend 24.
Specifically, the plate 22 is of elongated, rectangular
configuration and is bent at approximately the longitudinal center
thereof to form the two leaves 26 and 28. The rectangular portion
defined by the leaf 26 is attached to the side 16 of the handle
section 10 at the sight window 14, thus the leaf 28 is spaced
outwardly from the side 16 and, as will be discussed, presents a
spacer element or tab which is particularly useful in aligning the
arrow for proper flight.
The portion 26 of the support plate 22 is affixed to the side 16 by
an adhesive strip 30 which, prior to use, is covered with a
removable backing 32 that is ultimately peeled from the strip 30
(FIG. 6) just prior to attaching the device to the bow. An arrow
rest in the nature of a flexible finger 34 is carried by the tab 28
and extends forwardly and outwardly therefrom when the device is
secured to the bow in its proper orientation. The finger 34 has a
tapered outer end 36, an inner end 38 fixed to the tab 28, and a
bend 40 intermediate the ends 36 and 38 which is disposed adjacent
the forward edge 42 of the tab 28.
From the foregoing it may be appreciated that, besides the adhesive
attaching strip 30, the arrow supporting device of the present
invention is composed of two parts, the support plate 22 and the
arrow rest finger 34. Both of these components are preferably
composed of a suitable metallic plate material such as phosphor
bronze or annealed steel. It is important to note that the support
plate 22 is of significantly heavier plate stock than the finger 34
for the purpose to be discussed hereinafter. Permanent attachment
of the finger 34 to the inner surface 44 of the tab 28 is readily
accomplished by such means as soldering the inner end portion 38
directly to the surface 44.
In use, referring to FIGS. 2 and 3, it may be seen that the shaft
18 of the arrow overlies the outer end portion 36 of the finger 34
and engages the forward edge 42 of the spacer tab 28. Accordingly,
the arrow shelf 12 is not used; instead, the arrow is supported by
the finger 34 and is also positively maintained in a predetermined
spaced relationship to the side 16 of the bow by virtue of the tab
28 against which the shaft 18 also rests. The line of bend 24 in
the support plate 22 permits the archer to move the tab 28
laterally in the window 14 to set this spacing between the side 16
and the shaft 18. This is important since the axis of the shaft 18
must be aligned with the path of the bowstring or the thrust
imparted to the arrow by the bowstring will propel the arrow to one
side or the other of the intended path of travel. Furthermore, it
is apparent that arrow shafts of different diameters will require
different spacing from the side 16 in order to provide the desired
alignment with the bowstring. In the present invention, the archer
may conveniently adjust this spacing as needed by bending the
spacer tab 28 about the line of bend 24 until the proper position
is reached.
Referring particularly to FIG. 4, the finger 34 is shown in an
inwardly flexed position depicting the action of the finger after
the arrow is released and at the time that the feathers of the
arrow are passing the bow. By this action, the feathers meet
minimum resistance as the arrow is shot since the finger 34 yields
upon contact by the feathers to both minimize the deflection of the
arrow that would otherwise occur with a stationary rest and also
prevent the feathers from becoming damaged. In contrast to the
finger 34 of the present invention, it may be appreciated that a
stationary rest such as the shelf 12 tends to impart this undesired
deflection to the arrow as well as damage the feathers as they are
necessarily brought into sudden contact with the ledge as the arrow
is shot.
The difference between the plate stock employed to form the support
plate 22 and the finger 34 may now be readily appreciated. In the
case of the finger 34, it is desired that the finger be laterally
flexible so as to minimize any interaction with the feathers when
the arrow is shot, as discussed above. Conversely, with respect to
the leaf 28 of the support plate 22 that forms the spacer tab, it
is desired that this tab remain in the position selected by the
archer, yet both the tab and the finger must move together as the
tab is positioned so that the finger will be properly disposed to
receive the shaft 18 regardless of the spacing selected. To this
end, the inner end portion 38 of the finger 34 is fixed to the tab
28 and the finger normally extends along the inner surface 44
thereof to the bend 40, whereupon the finger then projects both
forwardly and laterally outwardly from the forward edge 42 in
clearing relationship to the tab 28. The plate material employed
for the support plate 22 has sufficient thickness to render the tab
28 rigid under lateral force which may be applied thereto upon
release of the arrow, thus the tab 28 remains in the selected
position as the arrow is shot. (Such lateral force is an undesired
result caused by sidewise movement imparted to the bowstring by the
archer as it is released, a behavior known as "archer's paradox.")
However, as discussed above, the line of bend 24 permits the archer
to easily select the position of the tab 28 in accordance with
shooting conditions.
