12 Claims. (Cl. 2-158) This invention pertains to apparel, in particular to an improved hand covering designed to protect the wearers hand from cold. As here illustrated, by way of example, the invention is embodied in a mitt or glove useful, for instance, by out-of-door workers, military personnel or others who are exposed to extreme cold, althrough the improved hand covering is of general utility. For particular example, aviators are often exposed for long periods to a near-zero atmosphere, where ordinary hand coverings such as woolen gloves or the like are wholly inadequate to cover hands which are of necessity exposed outside of the body garments for manipulating controls or operating firearms or other instruments or appliances.

The present invention has for its principal object the provision of a hand covering such as a mitten or glove so constructed as (while providing adequate protection against extreme cold) to have all requisite flexibility to enable the wearer to handle tools, operate machinery, actuate the controls of an airplane or manipulate firearms, etc. A further object is to provide a mitten or glove comprising heat insulation of a highly eifective character whose insulating properties are not lessened by exposure of the glove to external moisture or from the effects of perspiration from the wearers hand. A further object is to provide a glove or mitten comprising an outer skin and an inner skin which are joined only at their marginal portions, and with insulation interposed between said skins. A further object is to provide a glove which, although normally closely hugging the wrist of the wearer and although comprising an outer skin of a material which does not stretch easily, may nevertheless be donned or doffed without difiiculty. A further object is to provide a glove of the above character having at its palm and/ or finger portions elements operative to provide a firm grip about a part grasped by the gloved hand. Other and further objects and advantages of the invention will be pointed out in the following, more detailed description and by reference to the accompanying drawings wherein Fig. 1 is a plan view of a glove or mitt embodying the present invention, the glove being shown with its pahn side up;

Fig. 2 is a side view of the glove shown in Fig. 1;

Fig. 3 is a plan view of the glove of Fig. l with its palm side down;

Fig. 4 is a fragmentary section to large scale on the line 4-4 of Fig. 1, but omitting certain parts;

Fig. 5 is a diagrammatic sectional view substantially n the line -5 of Fig. 2 and to larger scale; and

Fig. 6 is a fragmentary view of the back of the glove at its wrist portion illustrating a slight modification,

Referring to the drawings, the numeral 1 designates the glove or mitt as a whole, this glove or mitt comprising the hand portion 2, the finger tip portion 3 and, as here illustrated, a portion 4 for the reception of the index finger, and a portion 5 for the reception of the nited States Patent 0 A 2,735,108 Patented Feb. 21, 1956..

thumb. Although, as here illustrated, the mitt or glove has a separate portion 4 for the reception of the index finger, it is contemplated that the glove may be made without such separate portion or on the other hand that it may be made with a portion for each individual fingerj As illustrated the glove comprises the wrist portion 6 which is designed snugly to embrace the wrist of the wearer.

Referring more particularly to Fig. 4, the improved glove or mitt comprises the outer skin S and the inner skin or lining L. The inner and outer skins S and L are of thin, flexible material which is impervious to moisture and preferably waterproof, it being contemplated that each of these skins may be of vulcanized gum rubber, although if desired, these skins may consist of textile material, for example stockinet fabric, frictioned with rubber, or of gum rubber with inclusion of reinforcing material such as textile fibers. Obviously synthetic rubber may be used, instead of natural rubber, or any other material, for instance a synthetic plastic having the requisite characteristics. In any event these skins would be thin and flexible. As illustrated in Fig. 4, the inner and outer skins are united at the wrist portion, for example, by a suitable adhesive binder 7 or by direct coalescence of the material forming the skins. Thus, if the skins are of gum rubber, they may be joined at the wrist during vulcanization. Preferably, the in ner and outer skins are separate from each other at other portions of the glove, although under some circumstances it may be desirable to unite them in direct contact with each other, for example, in forming the part 4 which receives the index finger, in order to insure a proper degree of flexibility at this point.

At all portions where the inner and outer skins are free from each other there is interposed between them a layer or layers of heat-insulating substance. As illustrated in Fig. 4, the heat insulation consists of plies 8 and 9 of textile material, bonded to the opposed surfaces of the outer and inner skins S and L. Preferably each of these textile plies is of a character such that loose fibers 10 or 11 project from one surface of the textile material. For example the textile plies 8 and 9 may be of a napped material, for instance woolen, or they may be pile fabrics in which the pile tufts form the projecting fibers 10 and 11. The textile plies 8 9 are so arranged that the free ends of the projecting fibers 10 and 11, if present, are opposed to each other, thus forming a resilient cushion between the inner and outer skins of the glove and providing a multitude of tiny air spaces thereby insuring a very eliective type of insulation between the inner and outer skins.

In order to facilitate the donning and dofiing of the glove or mitt, it is preferred to form a slit 12 (Figs. 3, 5 and 6) in the back of the glove, extending from the free end of the wrist portion 6 forwardly toward the finger tip portion, this slit being defined by theedges 13 and 14 which converge forwardly. To close the gap formed by this slit, a bellows tongue 15 is arranged within the mitt, this tongue being united by accordion elements 16 and 17 to the opposite edges 13 and 14 of the back of the mitt. The bellows tongue 15 may be of the same multi-ply construction (indicated at C, Fig. 5) as the other portions of the mitt, that is to say it may have similar waterproof and insulating characteristics thereby providing protection for the wearers hand at the back as well as at the palm portion. Desirably, the wrist portion is of a normal diameter such that it snugly embraces the wearers wrist, the accordion elements 16 and 17 possessing inherently resiliency such that they tend to contract and draw the edges 13 and 14 toward each other, but, if more positive constrictive waits force be desired than that resultant from the natural tendency of nesenaws re eontraena splif resilient bracelet B (Figs. 1, 2, 3 and SYbf any appropriate material may e ntersect be ween ts ia a atins Pl adia: seat h ;v ri t bsrfiqnr.
