2.3. .3532? BOWLINGfBALL ATTACHMENT Bernard J. Seurynck, Detroit, Mich.

Application August 13, 1945, Serial N0.v 610,533

3 Claims. 1 This invention relates to an improved finger sleeve or liner for the finger receiving opening of a bowling ball.

In my application Serial No. 533 343; filed April 29, 1944, I disclosed a liner for the finger opening ofa bowling ball which liner was adapted to I be removably adiustably positioned within such finger receiving opening te enable the bowler to obtain a better grip upon the ball to improve the control over the ball.

This invention relates to a sleeve or liner designed to serve the same purpose but so constructed asto embody a base portion which may be removably and adjustably secured within any conventional-finger receiving opening of a bowling ball which opening is ofthe proper size and which base portion has combined therewith a finger receiving sleeve portion that is readily attachable to the base or removable therefrom. Sleeve portions possessing difierent haracteristics may be employed in order to enable the bowler to select that particular type of sleeve which is found to be most suitable.

An object of the invention is to provide such a device wherein the base and-sleevea-re so constructed as to permit ready replacement of one type of sleeve with another type of sleeve.

'A further object is to provide a device of the character described wherein the sleeve is rota-t ably adjustable relative to the base,

A further object is to provide a sleeve which may; constitute a segment of a cylinder which may be secured totheba-sese as to serve as a partial liner for the finger receiving opening in the bowling ball to be engaged by the face of a-finger of the bowler.

Other objects, advantages and meritorious features will more fully appear from the following description, appended claims and accompanying drawing, wherein:

Figure 1 illustrates a fragment of a bowling ball partially broken away to show a finger re-' ceiving opening wherein is disposed a finger sleeve or liner embodying my invention.

Figure 2 is an enlarged sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a sectional view taken on the line 3-3 of Figure 2.

Figure 4 is an enlarged side elevation of the liner or sleeve and showing a modified embodiment as compared with the structure illustrated in Figure 2.

Figure 5 is a horizontal sectional view taken on the line 55 of Figure 4.

2. Figure 6 illustrates a liner portion of a modified form of construction.

Figure 7 illustrates a liner portion of a third modified portion of construction.

In the drawing the bowling ball is indicated as Ill and is. shown as provided with. a fingerre ceiving opening of conventional character It.

Within thisopening I2 is disposed an embodiment of the invention as shown in Figur 1.

The'improved' sleeve or liner comprises a base portion l4, whichvmay be formedoi metal; plastic or any other suitable material. away as shown in Figures 21 and 3 to provide guideways ipr a, plur l ty o suitable balli engaging plunger elements 16. Four, of these ballerigaging elements are shownin Figure 3. Each is.

ust t d. asheing ofl'a hape and'as having an i na ut r d portion adapted to be. pro-t i c ecl nto en a ment withthe wall f. t finger. receiving opening l2 of the ball upon, adjustable, tati n an. djustment. sc ew 1 he. outer. nd. i e. p un er. fimay b bent to p ovide, a flange I 5 which is adapted to frictionally engage the ball and which, may. seat 'withinarecess intlie bas 14' as bo nin E l le2'. The inner endo'ithe plun er. maybe bent over as. at. 'l] to been-- a edby thetaperedihead 2J1 (lithe screw. This flange l'llprevents. complete outward, withdrawal;

of the plunger I6.

This screw is shown as having atapered head 20 which head engages theinner endsof the T.- shaped elements it, to. urge. them outwardly. against the ball as the screw is threaded'dowh into a nut 22 which nut is fixed within a recess in the head l4. Through rotatable adjustment of the screw l8 it is possible to adjust the position of the plunger l6 relative to the base portion to position the liner within any finger receiving opening 12 of convenient size and also to position it at any place within such opening, either directly at the bottom or spaced thereabove and to secure the liner at such adjusted position. It is understood that base portions of difierent diameter may be provided for finger receiving openings of different diameter.

The base portion is adapted to have the sleeve portion removably secured thereto in any convenient manner. In Figures 1 and 2 this sleeve portion is shown as comprising a segment 24 of a cylinder. This sleeve is provided at one end with an internally threaded ring 26. This ring is adapted to be threaded upon an externally threaded portion 28 of the base as shown in Figure 2. The sleeve segment 24 is here shown as constituting substantially half of a cylinder and This base i ut this cylinder may be formed of any suitable material such as rubber, plastic, metal or stiff fibrous or composition material. The sleeve may have any desired length. It may taper as shown to an edge adjacent to the surface of the finger receiving opening l2. 7

In Figure 4 the base. I is provided with the engaging elements l6 as hereinabove described and a screw adjustment is provided to adjust the position of these elements I6. This screw is not shown in Figure 4 because such figure is an elevation of the base and the screw is within its interior. In Figure the head 20 of the screw is shown as are the inner ends of the plungers I6. This base differs in detail from the one shown in Figure 2 in that it is provided with a circumferential channel or groove 30 within which is received the inturned edge 32 of an end piece 33 which end piece is attached to the sleeve segment 24. This end piece may be formed of metal. In Figure 4 the sleeve segment is shown as formed of a stiff composition of fibrous material.

In Figure 6 the sleeve segment is shown a internally corrugated or roughened to facilitate frictional gripping thereof. It has an end piece 36 fastened thereto. This end piece is provided with inturned projections 38 which 'areadapted to be received within the groove 30 of the base. This grooved base may be of the character shown inFigure4.

In Figure 7 the sleeve is shownas a full circumferential sleeve 40 which is longitudinally split as at 42 and is provided with an end piece 44 having an 'inturned edge similar to that shown in Figure 6 adapted to engage within a .groove such as 30 shown in Figure 4 to secure the sleeve to the base.

It is apparent that any of these different types of sleeves might be secured to a base such as shown in the drawing and that a bowler might try out different sleeves and select the one found most suitable. It is also apparent that the sleeve prising, in combination, a base portion removably receivable within said hole, means supported by and within the limits of the base having a part operable to be projected outwardly therefrom to detachably engage the ball within the hole, a cylindrical sleeve segment detachably coupled with the base above said part and projecting upwardly therefrom to overlie a portion of the surface of the hole. y

2. A finger sleeve for a bowling ball compris ing, in combination, a base receivable within the finger receiving hole of a bowling ball, engaging ;means carried by the base including ball contacting parts slidably supported within ways in the :base to be projected through said ways outwardly radially beyond the base to engage the ball and a may be rotated relative to the base to the desired 1. A finger'sleeve adapted to be disposed within the'finger receiving hole of a bowling ball comscrew supported within the base operable to actuatei said parts into engagement with the ball within the hole to removably position the base within the, hole, said base having a circumfen ential groove above said vvays',-a sleeve having a; part removably seated within said groove-to detachably secure the sleeve to the base. r

3. A finger sleeve for thebowling ball com -t prising, in combination, a base receivable within the finger receiving hole of the bowling ball, means carried by the base including ball engaging parts slidably supported within ways inthe base within the limits thereof to be projected out-V;

wardly beyond the'base to engage the-ball and a screw supported within the limits of the base and operable to actuate said parts outwardly, said base having a circumferential groove thereabout drical sleeve segment having an inturned flange removably seated within said groove securing the sleeve to the base, said sleeve being rotatably adjustable about the base. 1
