Patented Mar. 1, 1932 UNITED STATES PATENT OFFICE LBCHEBS BOW Application Med January I,

This invention relates to an archers bow and particularly to that type of bow which 1s provided with an opening through the handle portion through which the arrow to be shot is projected.

An advantage of this type of bow over the ordinary bow wherein the arrow is projected along the side of the how when the string 1s released is that the arrow during-the entlre time that it is being propelled forward by the string is located in the direct l neof the application of the propelling force of the string so that the arrow-will not be sub ected to any lateral strain such as occurs when the arrow is projected along the side of the bow.

One feature of my improved bow relates to adjustable means for supporting the arrow as it is being dischsrrged whereby arrows of different diametiical size can be always held in substantially the axial-line of the bow.

Another feature ofthe invention relates to a bow of this type which has an improved sighting device by which the archer'can readily and accurately obtain the proper-elevatlon of the bow hand and can also readilyobtain the correct alignment ofthe arrow wlth the target.

In order to give an understanding of the invention, I have illustrated in the drawings a selected embodiment thereof which will now be described after which the novel features will be pointed out inthe' appended claims. 1

Fig. 1 is a View of a bowembodylng my invention Fig. 2 is a view of the handle portion of the bow looking from the belly side;

. Fig. 3 is a side view of Fig. 2.

In the drawings 1 indicates generally the bow and this is formed withthe handle portion 2, the two limbs 3 and 4 and the usual. string 5. The handle portion of the bow is provided with an opening 6 through which the arrow is discharged, said opening being large enough to. permit the feathers of the arrow to freely pass therethrough. This opening 6 is in the axial line of the bow and hence whenthe arrow is discharged it moves in a path which is in exact alignment with 'bow' pullin 1931. Serial in. 507,303.

the direction in which the propelling force is applied to the arrow by the string.

Projecting into the opening 6. are two adjustable arrow rests 7. Each rest is provided with a rounded arrow-engaging face 8 and 55 is formed with a screw-threaded stem 9 which screws into a sleeve 10 that is secured in the bow at the side of the opening 6.

11 indicates lock nuts WhlCh are screw threaded tothe stems '9 and by which the. o0 arrow-supporting posts may be locked in any adjusted position. i

I will preferably employ two such arrow rests, one of which extends horizontally at one side of the opening 6 and the other of I which is located at about 120 therefrom on the other side of the center of the how, the latter rest projecting upwardly and inwardly as shown. These two arrow rests thus positioned make a proper guide for the arrow (which is indicated in dotted lines at 12) as it is projected when the string is released but they do not interfere with the feathers13 of the arrow.

Another feature of my invention relates 7 to certain improvements to assist the archer not only in getting the correct elevation for the bow-arm for targets placed at different distances but also to assist him in getting his arrow properly lined up with reference to the 30 target.

These improvements consist in a sighting slot 14which is formed in the bow and which extends through the bow from the belly to the back in the line of the axis of the bow and through which the target is visible for all ranges except very long ranges at which the arrowis shot with a high trajectory. In the construction herein shown the sighting slot l i extends from the opening 6 but it is not necessary that this sighting slot should communicate with the opening 6. In fact, this sighting slot feature might be embodied in an ordinary bow which was not provided with the opening 6 through which the arrows are projected. 1

When shooting accordingto the conventional pointof aim method with an ordinary forty or fifty pounds and at distances 0 sixty yards or under the point of aim on which the tip of the arrow is sighted when the bow is fully drawn usually is between the target and the archer so that the target is visible above the arrow.

\Vhen my improved bow is used in shooting the shorter ranges, that is, ranges of sixty yards and under, the archer may obtain the correct alignment by drawing t ebow and holdin it so that the target will be visible throug the sighting slot 14. For obtaining the correct elevation for any predetermined distance the bow arm (that is, the arm by which the bow is held) will be raised or lowered so that the target willappear at different portions of the slot 14 depending upon the distance being shot.

In order to assist in obtaining the correct elevation I propose to use a sight 15 which is adjustable vertically of the sighting slot and with which the archer sights the gold or bulls eye of the target. \Vhile any desired sightlng device may be used that herein shown is in the form of a peep sight, it comprising a ring portion 16 through which the archer sights the center ortion of the target, said sight having a sig ting finger 17 rising from the bottom of the ring to approximately the center thereof. This sighting device is provided with a hub portion 18 which is screw threaded to the end of a clamping screw 19 that extends throu h a vertical slot 20 formed in oneside of the ow.

21 is a clamping nut screw threaded to the clamping screw 19 and which engages the outside of the bow. By tightening the clamping nut 21 the sighting device ma be rigidly retained in any position up an down the slot 20.

The side of the bow may he graduated with suitable graduation marks 22 which give the archer an indication as to the proper setting of the sight 15 for different distances. The setting for any distance will vary for different archers and also for difi'erentbows and arrows of different weight but the correct setting for any bow and any set of arrows can be readily determined by experimenta tion.

In using the bow for shooting at any given distance the archer will adjust the sight 15 to the pro er point for such distance and in drawing the bow he will adjust his bow arm so that the sighting point 17 comes in the direct line of vision between the eye and the center of the target. In other words, he will sight the point 17 on the center of the target. This will give not only the proper elevation but also the proper alignment of the arrow to make a perfect shot.

While it is within my invention to incorporate this improvement in a self bow yet I v refer to make the handle portion 2 of the ow separate from the limbs 3 and 4. The handle portion may be made of any suitable material such as metal, fibre or hard rubber,

etc., and I will preferably constructit with sockets 23 and 24 at opposite ends into which are set the limbs 3 and 4 of the bow. These limbs may be secured in the sockets 23', 24 in any appropriate way.

In the construction shown, the limbs are retained in place by means of screws 25 or clamps but any other means for this urpose may be employed to make them ad ustable.

One advantage of this construction is that 7 either of the limbs maybe readily disconnected from the handle portion to facilitate storage or carryin of the bow and the limbs can be readliy ad usted to lace the string in perfect alignment with tlie bow.

The portion 26 of the handle member 2 constitutes the portion which is grasped by the archer when using the bow.

I claim:

1. An archers bow having an openin through the handle portion thereof through which the arrow to be shot is projected, which opening is large enough to permit the feathers of the arrow to freely pass therethrough, and adjustable rests extending into the opening from the outer wall thereof and on w ich' the arrow is supported as it is projected.

2.
