RESILIENT GRIP.

Application filed April 19, 1923. Serial- No. 633,193.

To all whom it may concern Be it known that I, THOMAS EMIL GJoRUr, a citizen of the United States, and a resident of Chicago, in the county of Cook and State .of Illinois, have invented a new and useful Improvement in Resilient Grips, of which the following is a full, clear, and exact description. 1

My invention relates to improvements in resilient grips, and more particularly to resilient grips constructed of crude rubber,

or an unvulcanized rubber compound, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a resilient grip of the character described that is constructed of cohesive and elastic tape adapted to be wound around the han Y dies of tools, oars, farm' and household implements having handles, gripping members for supporting articles, such as fishing rods, golf sticks, baseball bats, tennis rackets, and the like.

A further object of my invention is to provide a resilient grip of the character described which because of the insulating qualities of the material, may also be employed as an insulating grip, suchasis desirable for the handles of electricians pliers, control levers, and the like.

A further object of my invention is to provide a resilient grip of the character described constructed of a rubber tape in which the frictional and elastic nature of the material provides means whereby the tape may adhere firmly to smooth surfaces, such as the varnished surface of a golf club handle or the like.

A further object of my invention is to rovide a resilient gripv in which the coesive and elastic properties of the tape employed provide for the uniting of the adjacent edges of the tape as it is wound about the handle, and therefore provides a continuous and unbroken surface which closely conforms with the contour and configuration of the handle.

'A further object of my invention-is to provide a hand grip of. thecharacter described that is constructed of tape in which diagonal marking lines are impressed or otherwise fixed upon the surface of the tape, whereby the tape may be cut so that the adjacent ends of a single length of tape the tape 1.

may meet uniformly as in the production of an endless-belt or band.

Other objects and advantages Wlll appear Figure 2 1s a sectional view along the line 22 of Figure 1,

Figure 3 is a view of a golf club handle upon which my improved resilient grip is fixed, and

Figure 4 is a sectional view of a modified form of the tape illustrated in Figure 1.

In carrying out my invention, I provide a tape 1 constructed of crude rubber, or the crude rubber compound that has retained its cohesive and elastic properties. This tape is generally cut from smooth sheets, although crude rubber, known as crepe rubber, that is rubber having an uneven surface, may be used equally as well. 1 The tape 1 is cut approximately one inch in width. (This dimension is purely optional.) 'A relatively narrow band of rubber 2, cut from the same sheet as the bands of tape 1, is securely fixed to the inner surface3of This may be done by laying the band 2 longitudinally along the surface 3 and pressing the band 2 upon the band 1, or a cement may be employed, although it is not necessary to use cement because of the extreme cohesive properties of the crude rubber. The band 2 is disposed at exactly the mid point of the tape 1 (see Flgure 2). A paraffinsheet 4 is employed between the adjacent layers of the tape 1 when it 1s packed in roll form, as shown in Figure 1. This is so that the layers will not adhere to one another,. and also to preserve the cohesive properties of the rubber.

From the foregoing descriptlon of the various parts of the device, the operation thereof may be readily understood. The tape when applied to a handle 5, or the like, to form my improved resilient grip, is wound around the handle in a spiral manner, so that the ad'acent edges 6 of the spiral windin touc one another. These edges will unite due to the, cohesive property of the tape and therefore will provide a uniform and continuous surface. lhe tape 1 is wound around the handle 5 so that the band 2 is on the inside and therefore ribbed protrusions 7 will appear in spiral arrangement on the grip. There will be no sharp edges, however, due to the fact that the band 2 is on the inside, and that the band 1 is pressed downwardly thereby.

In applying the tape, it is absolutely essential that the tape be stretched slightly as it is wound about the handle 5 so that in contracting, it may adhere firmly to the surface of the handle.

The ends of the tape are cut diagonally along marking lines 8 provided on the outer surface of the tape, and the outer ends of the tape are placed under the first and last windings, respectively, and by this means held against accidental unfastening.

In Figure 4- I have shown a modified form of the tape used in my improved resilient hand grip in which in place of employing a band 2, 1 construct the tape with its inner face 1 having an inwardly extending integral flange 2 thereupoln When the tape is constructed in this manner, it may be forced through a die having the configuration of the cross section illustrated in Figure 4. The use of this modified form is precisely the same as the use of the preferred form of the invention. My resilient grip is particularly well adapted for supporting articles, such as fishing rods, golf clubs, tennis rackets, and the like, in which a grip whichwill not adhere to the hand is most essential, but in which the entire frictional and resilient properties are necessary.

I claim:

The combination with a substantially cylindrical handle member of a tape having adhesive and elastic properties, said tape being provided with a longitudinally disposed, relatively flat rib on one side thereof extending continuously throughout the length of said tape, said tape being wrapped around said handle member in spiral fashion with said rib in contact with said handle whereby a grip having a spiral raised portion is provided for said handle.
