11 Claims.

This invention relates to a pneumatic boxing glove and the primary object of this invention is to provide a pneumatic boxing glove of simple and eflicient construction having a striking surface which is cushioned. by air thus reducing to a minimum the danger of injuring a person who is struck with the glove and providing a more resilient striking pad for the hand of the user of the glove.

When a boxing glove is on the hand and the hand is clenched, the boxing glove will be held in a clenched shape in which it conforms substantially to the shape of the letter J. When a pneumatic boxing glove is inflated the resilient air pressure tends to straighten the glove out and if the boxing glove is free to substantially straighten out it becomes a tiring strain on the hand of the boxer to hold the glove clenched. It is an object of this invention to provide a pneumatic boxing glove of this nature which is formed of rubber and which, when inflated, will assume substantially the clenched shape required for use without requiring any muscular efiort on the part of the user.

Another object of the invention is to provide a pneumatic boxing glove which is formed with two side by side pneumatic compartments having therebetween a wall with an opening of small size therein whereby the pressure between said two compartments will always be substantially equal but sudden rushes of air from one compartment to the other or to the atmosphere will be prevented.

A further object of the invention is to provide a pneumatic boxing glove of this nature which is shaped so as to provide spaced apart points of contact with the clenched fist and spaced apart points of contact with the object struck by the glove so that the glove will be prevented from rolling when a blow is delivered and the tendency to sprain the wrist and hand of the user will be minimized.

Another object of the invention is to provide a pneumatic boxing glove formed of rubber which may be used without any cover or casing or which may, if desired, be placed within a cover or casing of leather or any desired material.

Other objects of the invention are to provide a pneumatic boxing glove which is simple and inexpensive in construction and which is very satisfactory in use.

Other and more specific objects of the invention will be apparent from the following description taken in connection with the accompanying drawings.

Fig. 11 is a plan view showing the two parts used in constructing the glove illustrated in Figs. 9 and 10, as said parts may appear before they are placed together and vulcanized to form the glove.

Like reference numerals designate like parts throughout the several views.

Figs. 1 to 4 show a pneumatic boxing glove preferably of integral construction molded, vulcanized or otherwise made of the desired shape. This glove comprises two tube like receptacles or compartments II and I2 positioned side by side and separated by a Wall 13 which extends longitudinally of the glove in the medial plane of the same and has a small hole 2|, therein. The body of the glove is permanently shaped to the curved or clenched shape shown in the drawings the outermost or striking portion being curved along substantially cylindrical lines as viewed from the side and the inner or palm portion being of suitable shape and size to receive the clenched hand of the user. When viewed from the side the glove is relatively narrow at the wrist and widens out and becomes thicker at the portion in front of the position of the clenched fist of the user and then tapers to a thin portion M at the tip and terminates in a fiat portion I5 which extends into the palm portion of the glove and has a grip portion l6 formed at the end thereof. The glove may be described as of approximately the shape of a letter J.

A wristband II, which may be laced or otherwise fastened around the wrist of the user, is secured to the wrist portion of the glove.

Cross sectionally considered the glove presents the appearance of two side by side tubes separated by the wall I3. A groove I 8 extends around the outside of the glove at the locationof the wall l3 and another groove I9 extends around the palm or inside portion of the glove. groove I8 provides a depression on the outer or striking surface of the glove so that when the glove strikes against a relatively flat surface.

it will have two spaced apart points of contact instead of a single medial pointof contact and the tendency of the glove to roll will be minimized. The groove 19 on the inner surface of the glove helps to provide a receptacle for the knuckles of the wearer and the inwardly protruding portions of said glove on each side of the groove 19 provide spaced apart points of contact for the knuckles'of the wearer thus further minimizing the tendency of the glove to roll sidewise on the hand when a blow'is struck. Overcoming the tendency of the glove to roll'greatly lessens the danger of the user spraining his wrist when blows are struck withthe glove. The grip portion I6 is connected at its respective ends with two tie members 20 which are connected with the'outer side walls of the glove sothat the grip portion I 6 is firmly secured to the body portion of" the glove.' r

When the glove is in use the grip member Iii is firmly gripped in the hand of the user, the wrist portion I1 is laced snugly about the wrist and the clenched knuckles rest-against the inner portions of the two compartments H and I2 of the glove. This gives the hand a firm connection with the glove and adequately protects all portions of the hand so that it will be substantially impossible for the wearer of the glove to strike an adversary with the hand instead of the glove. V H In the event the rubber which forms either of the receptacles or compartments H or I2 is torn or burst by a blow and one compartment collapsed the air in the other compartment will escape slowly through the small hole 2| and the other compartment will afford an ample cushion to prevent the fist of the userof the glove from coming in direct contact with the person struck. This safeguards the person who is struck with the glove against injury'due to the bursting of one pneumatic compartment of the glove. A valve 22 is provided in the wrist portion of the glove to permit inflation. A flap 23 is provided to cover the valve 22. p The wall 13 is positioned in the medial plane of the glove and extends throughout the length of the pneumatic compartments. .This wall provides stability to the glove and helps to'overcome the tendency of the glove to straighten outwhen it is inflated. By forming the glove in the clenched shape required in use and by providing the wall I3- therein to help overcome the tendency of the glove to straighten out it is possible to provide a glove which does not subject the hands of .the'user'to any. gripping strain to hold the glove clenched or closed when the glove is in use. The palm portion of the glove conforms to the shape of the hand and is pressed the user.

snugly against the hand by air pressure when the glove is in use.

In Figs. 5, 6 and 7, we have shown an improved form of this boxing'glove embodying all of the essential and important features of the glove shown in Figs. 1 to 4, but differing somewhat in details of construction. The glove shown in Figs. 5, 6 and 7 comprises two side by side pneumatic compartments or

air receptacles

24 and 25 separated by a medial wall 26 having a small hole 21 therein. The pneumatic compartments 2i and 25 are curved to conform to the closed or clenched shape of the glove. Each pneumatic compartment is preferably formed of two pieces of rubber and these two pieces of rubber are vulcanized together at the locations which extend along the sides of the hand of the wearer to form'side portions 28 between which is a pocket 29 for the reception of the hand. The wrist portion is open on the inner side, as shown in 'Fig. 6, and tie strings 30 or other suitable securing means are provided in connection with said wrist portion to fasten about the wrist of The pneumatic compartments II and I2 extend from the location of the wrist along the back portion of the glove, around the front or striking portion and thence along the palm portion of the glove almost back to the wrist thus substantially surrounding the hand and making it substantially impossible for the user of the glove to strike an adversary directly with his hand.

Preferably a lining 3|, as of cloth or leather,

is provided within the pocket 29 which receives the hand. As the hand is substantially completely enclosed when in the pocket 29 and as the glove is resilient and fits snugly to the hand it is not essential to provide a grip in this boxing glove. Howeven'if desired, a grip may be extended between the side portions 2828. This grip may besecured to the side portions 2828 or it may be secured only to the lining 3|. A grip 32 which is secured only to the lining is shown in Fig. 8. v V v In use the glove disclosed in Figs. 5, 6 and '7 is substantially the same as the glove disclosed in Figs. 1 to 4. The two

air receptacles

24 and 25 provide for two points of contact, both with the knuckles of the user and the object against which the blow is deliveredthus reducing to a minimum the tendency of the glove to roll. The glove has no'tendenc'y to'straighten out and does not have to be held in closed or clenched position by the hand. The medial wall 26 provides a reinforcing between the two

compartments

24 and 25 and the small hole 21in said wall 26 provides for equalizationof pressure between the two

compartments

24 and 25,but prevents a rush of air from one compartment to the other when one compartment receives the impact of a blow and prevents a rapid escape of air from one compartment in case the wallof the other comparte ment is broken,

A valve 33 is provided in the wrist portion of the glove shown in Figs. 5 to '7.

back portion 35. vulcan i zing material is indicated by 31 in Fig. l1. Also a strip 38 of vulcanizing material is placed longitudinally of the back portion 35 mid way between'the two sides thereof. Also vulcanizing material 39 is placed on the wrist part of the back portion 35. The palm piece 36 is then stretched until it con forms in length to the back piece 35 and is placed face to face on the back piece 35.- The palm piece 36 is maintained in a stretched condition while the two: pieces are being vulcanized together. The vulcanizing unites the 'two

pieces

35 and 36 along the lines'of the vulcanizing material 3'! and 38 and at the wrist portion of said pieces, leaving the spaces between the vulcanizing strips 31 and 38 free from each other'to serve as air compartments. 'Suitable valve means is provided in the wrist portion ofthis glove and when the gloveis inflated, after it has been vulcanized or cured, the tension of the palm portion 36 will cause said glove to assume the clenched shape shown in Fig. 9. An extension or end tab 60 is provided on one of the glove portions, as on the back portion 35 and a grip member 4| is secured to this end tab 40. Side pieces 42 similar to the side pieces 20 in Figs. 1 to 4, connect the grip member 4| to the sides of the glove. Also a wrist band 43 is provided on the glove. Also a small hole 44 is provided in the wall 45 between the two compartments of the glove as shown in Fig. 10.

All of the gloves herein disclosed have the two side by side air compartments with the longitudinal wall between and the small hole in the longitudinal wall. Also all of said gloves have the fully clenched shape, when inflated, relieving the wearer of the necessity of exerting muscular effort in holding the glove closed. Also all of said gloves are designed for use without any covering external to the rubber.

These boxing gloves are inexpensive and are especially well adapted for the use of amateurs and persons who wish to practice boxing.

The gloves are not heavy and are soft enough so that the boxers may strike as hard as they wish without danger of seriously injuring an adversary. Dividing the glove into two compart- 'ments with a small communication opening between them makes it substantially impossible for fair to rush out of one part of the glove and permit the fist to strike directly against the object which receives the blow of the glove.
