Description

Aug. 27, 1963 J. R. MccoRMlcK SLINGSHOT Filed Feb. 19, 1962 INVENToR. James R /c/za/o Mc Co/m/c/f ATTORNEY United States Patent O 3,101,704 SLhJGSHOT James Richard McCormick, RJR. 1, Allegati, Mich. Filed Feb. 19, 1962, Ser. No. 173,917 11 Claims. (Cl. 124-20) l'his invention relates to slingslots. The main objects of this invention are,

First, to provide `a Slingshot which is highly eiiicient land `at the same time structurally simple.

Second, to provide a slingshot formed of relatively few parts, the parts being -assembled so :as to minimize stresses tending to break the connections for the parts.

Objects relating to :details and economies of the invention will appear from the description to follow. The invention is dened and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

FIG. l is a perspective view of a Slingshot embodying my invention, hands `of a user being indicated by dotted lines.

FIG. 2 is an enlarged fragmentary view partially in section on a line corresponding to line 2-2 of FIG. 1.

FIG. 3 is an enlarged fragmentary View partially in section on a line corresponding `to line 3-3 of FIG. 1.

FIG. 4 is a fragmentary view of a ngerpiece and projectile holder.

lIt will be noted that the illustration of FIG. 1 illustrates -applicants slingshot as being used by a left handed person.y

The Slingshot embodying the tapplicants invention comprises a forked handle designated generally by the numeral 1 Iand comprising the grip portion 2 land upwardly projecting laterally spaced -arms 3 which have bores 4 therethrough, these bores being disposed adjacent but in downwardly spaced relation relative to vthe upper ends of the arms.

The elongated tubular elastic members 5 are disposed through the bores or holes 4 in the `arms 3 being a slidable iit therein, that is, the bores 4 `are of such dimensions that the ends of the elastic members may be inserted therethrough and project forwardly therefrom to receive the conical clutch or anchor members 6. The -taper and dimensions of these anchor or clutch members are such that ltheir inner ends project substantially into the bores 4 when the members 6 are inserted in the front end of the members 5, see FIG. 2, so that pulling stress on the members 5 results in compressing clutching engagement thereof with the forwardly facing beveled portion 7 of the bore 4. The taper angle of said bores is substantially that of said bevels.

In the desirable embodiment illust-rated,the member 6 has .an inwardly beveled outer end portion 8 with which the outer end 9 of the elastic member 5 is in clutching engagement. Desirably ad-hesive is applied to this surface 8 as indicated at 10 which prevents any stripping off as a result of the forward edge 11 being engaged with some object, not as a use, but in the matter of handling.

The 4combined fingerpiece yand projectile holder -12 is desirably formed of leather which has fan inner surface 13 with projecting filaments, as is illustrated conventionally in FIG. 3. This member 12 has holes `14 at the ends thereof through which the inner end portions 15' of the members 5 are inserted with the portions 15 collapsed, the collapsed portion being disposed in side by side relation at 16 and iixedly secured together by the strips 17 wound `around the same, the strips having adhesive 18 on'their innersides which bonds the strips to Vthe parts around which they are wrapped and also the convolutions of the strips are bonded together. The elastic tubular members 5 are thus connected to the 3,101,704 v'Patentetil Aug. 27, 1963 lCe ngerpiece and projectile holder. The tubular stretch- :able members 5 are connected both to the handle Iand to the finger-piece in a wholly effective manner and in a mannerwhich yminimizes tearing or rupturing stress on the elastic material.

I have illustrated and described my invention in a highly practical embodiment thereof. I have not attempted to illustrate modifications which might be desirable in the form yof the handpiece or in the ngerpiece and projectile holder, as it 4is believed -that vthis disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent is:
