Filed Jan. 15, 1960, Ser. No. 2,664 3 Claims. (Cl. 2-21) Bowling or ten pin balls are gripped by the thumb and by one or two fingers and are accordingly provided with openings which extend substantially radially, these openings of course being in convenging relation. In the control of the ball, for example as when throwing a hook, aiming for the pocke or regulating the throw for a particular kind of spare, an important factor is the pressure exercised by the thumb, the opposed finger pressure being intended to be sufiicient merely to prevent the ball from slipping from the hand.
in the course of an evening devoted to bowling, due to the muscular effort imposed upon the thumb in the control of the ball and the necessity for the free release of the ball with minimum frictional pressure or drag of the thumb and fingers upon the walls of the openings at the moment of release, the thumb becomes swollen to some extent and therefore does not have its suitable fit in the thumb opening and also becomes subject to considerable abrasion and soreness, all of which, in addition to and in connection with the discomfort, adversely aifects the accuracy of play. As these conditions develop progressively there is a reflex tendency on the part of the player to relieve to some extent the pressure of the thumb and to transfer some of the controlling pressure to the finger or fingers with the result that these also tend to swell and become sore and abraded.
These objectionable conditions are well known among bowlers and have obtained throughout the period in which the game has been played. In order to overcome or minimize them various modifications of the thumb and finger openings have been proposed, these in general taking the form of cushioning insents permanently fitted in the openings. The constructions proposed have not been altogether satisfactory for their intended purposes and moreover greatly increase the cost of manufacture of the bowling ball with added increase in the maintenance of service in the bowling alleys where a large number of balls are required, varying in weight, in the diameters of the thumb and finger openings and in the relation of the Openings to one another, in order that a ball may be selected which best measures up to the span of the hand and the requirement for the proper fit of the thumb and fingers in the openings.
We have found, empirically, that the objectionable conditions above pointed out may be relieved by means of a device which may be fitted upon the thumb, carried independently of the bowling ball upon the person of the individual, will be responsive to adequate thumb pressure in the control of the bowling ball, will enable the release of the bowling ball without frictional drag, will at all times have an appropriate fit in the thurnbopening, and will impose no added reflex burden upon the finger or fingers.
This invention relates to a thumb carried thumb protector and thumb actuated gripping device for use with standard bowling balls.
Its objects are, with optimum economy, to provide for adequate control of the bowling ball and for its free release while at all times protecting the thumb against swelling, soreness and abrasion.
The device of the invention in the embodiments herein shown includes an outer member of circular crossappropriate metal.
diametrically to have an accurate, yet free and easy, fit' in the thumb opening, is shaped and proportioned longitudinally to conform to the outline of the thumb and to accommodate the extension of the knuckle of the thumb as the thumb is bent in the exercise of pressure upon the wall of the thumbopening, and an inner member of yieldable resilient cushioning material, such as foam rubher, which is of circular cross-section. As herein shown the inner member is cemented to the outer member, conforms to its longitudinal outline and projects with thumb protecting eifect, beyond the upper and lower edges of the outer member. For brevity and convenience the device may be called a bowlers protective thumb ring.

Referring/to FIGURES l to 5:
The bowling ball B is formed with a thumb opening T and a finger opening F, some balls having one finger opening and others having two. In gripping and controlling the ball the thumband fingers are inserted in these openings as shown in FIGURE 1.
The device includes an outer member 1 of circular crosssection and which in this particular form is of substantially rigid material such as a suitable plastic oran The member 1 in the longitudinal direction is shaped to conform to the outline of the thumb and has a wall part 2 overlying the inner side of the thumb and having a longitudinal extent substantially conforming to the length of the thumb and an opposed shorter wall part 3 which overliestthe outer side of the thumb. The lower end of the wall part 3 terminates above the knuckle of the thumb and substantially above the lower end of the wall part 2 with the result of an open clearance 4 into which the knuckle of the thumb extends and which enables the bending. of the thumb. with. the knuckle free from contact with the wall of the opening T. The member 1 along its upper edge is shaped to conform to the joint between the thumb and the hand and in this shaping, with the thumb inserted into the opening T, therwall part 3 projects well beyond the opening and the wall part 2 terminates at the face of the ball B. The lower edge of the member 1 of course extends obliquely from the wall part 2 to the Wall part 3 and is preferably of ogee curvature as shown at 5 in FIGURE 1. The upper edge of the member "1 also extends obliquely from the wall part 2 to the wall part 3 and is similarly and preferably of ogee curvature as shown at 6 in FIGURE 1.
The device also includes an inner member 7 composed of resilient cushioning material such as foam rubber and which conforms in shape and dimensions to the member 1. The blank for the member 7 is shown in FIGURE 5 and is fashioned into circular cross-section and fitted conformably within the member 1 to which it is secured by any suitable cement. The member 7 is of greater longitudinal extent than the member 1 whereby it has a thumb protecting portion 7a of annular section which projects suitably beyond the upper edge of the member 1 with its edge conforming in outline to the upper edge of the member 1 and a thumb protecting portion 7b of curved section which similarly projects beyond and conforms in outline to the lower edge of the member 1.
In annular section and longitudinal extent the devices are made in sizes from which a selection may be made which will conform to the thumb of the particular individual. Diametrically the member 1 will be somewhat less in dimension than the diameter of the thumb opening T in order that as fitted upon the thumb it may be freely inserted into and removed from the opening T.
In effecting the control of the ball pressure is applied by the thumb directly against the member 7 which protects the thumb by serving as a cushion and the wall portion 2 of the member 1 is thereby pressed against the adjacent wall portion of the thumb opening T with such force as will enable the player effectively to control the ball. At the moment of release of the ball the thumb pressure is withdrawn and the member 1, because of its smaller diametrical dimension, is then freely removed by the thumb from the opening T with no appreciable frictional resistance by the wall of the opening.
It will be manifest that the thumb at all times is protected against swelling, abrasion and soreness. The portions 7a and 7b and the member 7 protect the thumb from sharp edge contact with the lower and upper edges of the member 1. The bearing of the member 7 upon the back of the thumb directly above the knuckle insures that the ring cannot be stripped from the thumb when the ball is released. Because the thumb is thus at all times protected there will be no reflex tendency to use the fingers in the control of the ball or otherwise than to prevent the ball from slipping from the hand.
Referring to FIGURES 6 to 9:
These figures show an alternative form in which the outer member, here designated 1a, instead of being of substantially rigid material is composed of somewhat yieldable solid material, e.g. suitably vulcanized rubber, which has the advantage of optimumly effective frictional engagement with the wall of the thumb opening. In order to prevent its deformation by the thumb the outer member 1a is pre-formed in its portion of annular section with an annular groove 8 to accommodate a binding ring 9 of any suitable rigid material, e.g. metal, the outer face of which is substantially flush with the outer face of the member 1a. In other respects the form shown in FIGURES 6 to 9 is similar to the form shown in FIG- URES 1 to 5.
In both constructions the thumb ring as an entirety is of circular cross-section dimensioned to have an accurate and secure fit upon the thumb and is characterized by l) a longer wall part substantially conforming to the length of the thumb and to overlie its inner side, this part being adapted for frictional engagement under the pressure of the thumb with the wall of the thumb opening,
(2) a shorter wall part in opposed relation to the longer wall part to overlie the outer side of the thumb above the knuckle, (3) its internal resilience and yieldability, thereby to serve to cushion the thumb, and (4) the open clearance due to the relation between the longer and shorter wall parts, the clearance accommodating the knuckle and enabling the thumb to be bent in its application of pressure by means of the longer wall part to the wall of the thumb opening.
Words indicative of location in the foregoing description and in the claims, namely, upper, lower, above," and below, are based upon the position of the thumb ring as shown in FIGURE 1.
