United States Patent SOUND REPRODUCER George D. Grazier, Tyrone, Pa. Application January 6, 1953, Serial No. 329,874 1 Claim. (Cl. 46-189) The invention relates to a device for mechanically reproducing a sound similar to the vocal call of a wild turkey, and to be used by hunters and others to attract wild turkeys to the sound.

This device is simple to manufacture from materials easily obtained, and all the parts of same are conveniently and compactly contained in a small case which can be carried in a pocket of the hunters clothing.

This device, when operated by those skilled in this art, will reproduce to perfection the vocal cal of a wild turkey and attract same to the sound.

In the drawings,

Figure 1 is a perspective view of the case closed, and containing all the parts of the sounding device.

Figure 2 is a perspective view of the case with the top open and showing the sound reproducer as would appear in operation.

Figure 3 is a sectional view taken on line 1-1 of Figure 1, showing arrangement of assembled parts in the case.

Figure 4 is a plan view of the sound reproducer.

Figure 5 is a plan view of the top of the case and arrangement of parts in same.

Referring to the drawings, I have illustrated my invention as comprising a hollow wooden, preferably cedar, rectangular box shaped sound reproducing device, having a bottom 1, end walls 22, top 3, side 4, and sounding panel 5.

It will be noticed, small round holes 6-6 have been drilled through each end wall 22 of an approximate diameter equal to /3 the width of the end wall. Said holes are located in the center of the end walls, and a distance from the top of the end wall to the center, equal to /2 the width of the end wall.

Two slots 77 are cut in the top 3, approximately wide, and in length equal to V5 the length of the top 3, and equally spaced from each end. One slot 7 extends along one edge of sounding panel 5, and the other slot 7 extends along the edge of the side panel 4.

It has been found these holes and slots stabilize and eliminate distorted sounds.

The side 5 provides a sounding panel having a curved top projecting beyond the top of the sound reproducer and forming a contact edge 17.

Figure 1 shows the case of requisite dimensions made of wood, preferably black walnut, to hold all of the equipment and protect same when not in use. The top of the case is made to open, and two brass hinges 88, are riveted to the case. A catch 9 is also riveted to the case to hold the top closed when not in use. A small piece of sponge rubber 10, is attached inside top of the case. This sponge rubber presses against sound reproducer when the case is closed, holds same in place, and prevents rattling. A piece of slate 11, is secured to a Wood filler l2, inside the top of the case by two wood screws 1313. A tapered and beveled strip of wood 14, is also secured to the wood filler 12, by two wood screws 13-13, to provide a compartment 15, to hold a standard (tapered) piece of blackboard chalk 16. Chalk is securely held in place by said tapered and beveled strip 14 by placing chalk in wide end of compartment and sliding same in compartment until it wedges itself between tapered and beveled strip 14, and wood filler 12.. The chalk may be removed by sliding same back to the position in which it was inserted.

By rubbing the chalk 16, well over the slate 11, and holding the sound reproducer in one hand, and striking lightly the contact edge 17, over the slate 11 in a longitudinal movement to the slate, will produce a sound similar to the vocal call of a wild turkey.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent is:

A container for a sound reproducer comprising a case having an open top, a closure top cover carried by said case, said case adapted to removably receive a sound reproducer, a longitudinal hard element secured to the inner face of said cover, a tapered and beveled strip secured to the under face of said cover and spaced laterally from said longitudinal hard element thereby defining a chalk receiving compartment between said strip and said hard element, and a resilient member carried by said closure top cover constituting a sound reproducer contact bumper to firmly hold a sound reproducer within said case when said cover is closed.
