ments in Rubber Gloves; and I do declare that the followin is a full, clear, and exact description of the lnvention, which will enable others skilled in the art to Whichit appertains to make and use the same.

My invention relates to rubber gloves; and the object of the invention is to furnish a glove especially designed for use by surgeons and physicians and which is provided with a surface over the front of the fingers and thumb as nearly like the surface of the natural hand as is possible to produce mechanically.

In an all-rubber glove or gloves which are formed only of pure rubber without a special body it has been found by actual experience that they are not well adapted to surgical work,where the surfaceof the glove becomes saturated With blood, or for the delicate manipulations of physicians, because the surface is too smooth and slippery. Hence the fingers lack the grip or hold which the natural hand possesses by reason of its very slightly ribbed or roughened surface and without which even the natural hand would not be well suited to this kind of work. I have therefore sought to provide an otherwise all-rubber glove which will lit-snugly upon the hand, as usual with what may be termed a grained or very slightly ribbed surface, resembling most accurately the natural touch .or surface on the Working side of the bare or naked fingers. To this end I fashion a glove out of pure rubber formed by dipping, as usual ,forming an expansible allrubber body, and when said glove is otherwise completed I place a layer or strip of silk fabric or its equivalent,which'is non-expansible, upon the fore part of the fingers and thumb, which is firmly cemented upon the adhesive surface of said fingers and can be coated or covered with rubber by dipping or otherwise, so that the silk itself becomes practically embedded in the rubber and is not itself exposed. However, this embedding does not lose to the glove the slightly ribbed or roughened surface sought for, and the result is that where the silk has been laid there is just enough unevenness of surface to obviate the slippery smoothness of all rubber and to give the hand a grip orhold which is so nearly like its natural grip that there is no material difference in operation.

Now referring to the drawings, Figure 1 shows a plain front elevation of a rubber gauntlet-glove made after the manner of my invention. Fig, 2 represents a longitudinal sectional elevation of a finger much enlarged and with a wavy or corrugated bottom edge designed to illustrate a lengthwise section of the finger and of course magnifying the idea of corrugation or unevenness of surface which the introduction of asilk fabric affords. Fig. 3 is a cross-section of a finger still more enlarged as compared with Fig. 1' and showing also an exaggerated idea of the inlaid fabric.

As thus illustrated, A represents a purerubber glove made by dipping, as usual, and

of any desired weight, and upon the working faces of the fingers and thumb of this glove I place a suitable fabric strip S, preferably of silk and practically embedded in the surface of the rubber, as already described. A comparatively fine grade of silk not too closely woven will serve my purpose, and I may also have made a special fabric for this use with exactly the mesli best adapted thereto, and the material is not necessarily confined to silk, but may be a fine quality of linen or the like. However, in my present manufacture I am using silk exclusively. In

this instance I show the fabric as running about two-thirds around the finger. It might for that matter be a narrow strip along the finger or extend entirely around and also down over the palm of the hand. This, however, is a mere elaboration of the invention and is understood to be within the spirit of the invention and claim as presentedherein.

It will readily be seen that in addition to the roughened touch which this construction of glove affords and which is so essential to have there is the further and materialadvantage of having the engaging or gripping surface of the glove inelastic or non-expansible. I00

Then when a grip is made it will hold and her body and non-expansible finger-fronts,

not run away, as occurs when the rubber substantially as described. 10 stretches and surrenders the grip.
