LINED RUBBER GLOVE Filed March 20, 1946 2 Sheets-Sheet 2 gmmm f aflZ Patented Aug. 10, 1948 s PATENT OFFIQE 2 Claims.
The present invention relates to improvements in gloves and more particularly to rubber gloves and the like.
One of the objects thereof is to provide a simple, eflicient and inexpensive glove made of a composite rubber and fibrous material, the rubber being on its outer face and the fibrous material on its inner face.
A further object thereof is to provide a novel form of glove adapted for special use in handling chemicals, hot substances and the like, which has certain marked hand protecting qualities.
Another object thereof is to provide a hand insulating glove wherein use is made not only of employing an acid resisting material as a covering for the hand but also of air pockets at the finger tips of the finger portions thereof as well as around the wrist portion thereof.
A still further object is to so arrange certain materials shaped to cover the human hands that the encased hand will be rendered impervious to the harmful penetrating influence of foreign substances with which the outer surface of the glove comes into contact.
Another object thereof is to provide air pockets at finger tips of the glove made in accordance with my invention so that there will be a pair of spaced apart finger tips contributed alike by an outer rubber glove and an inner fibrous glove.
With the above and other objects in View, my invention consists in the combination arrangement and details of construction shown in the drawings and specification and then more particularly pointed out in the appended claims.
In the drawings, wherein similar reference characters designate similar parts throughout the respective views,

Referring to the drawings, which are merely illustrative of my invention, the various parts thereof are disclosed.
The present glove is designed to protect the hands of the wearer using same when he is engaged in certain kinds of work which calls for safety measures in preventing access from the outer surface of the glove into the hand .engaging surface thereof of harmful fluids or harmful sensations otherwise communicated. In this capacity I provide in fact two gloves, an outer glove made of rubber and an inner glove made preferably of non-rubber material such as of fibrous material. The rubber glove may be moulded or otherwise produced in a homoge neous body shaped to the outline of the desired glove. The fibrous glove will be made preferably from a pattern and out to the outlines of the pattern from the fibrous material. In doing this I propose to provide integral tabs as proiections extending beyond the finger tip ends of the fibrous glove to serve, when assembled in relation to the other parts of the finger portions of this glove section, as a means of conveniently and practically separating the tips of the finger portions of the rubber outer from the tips of the finger portions of the inner fibrous glove.
To this end the outer rubber glove, designated to, receives and encases snugly the inner fibrous glove ll so that there will be two layers of different materials composing the composite glove of my design, the parts of which overlie and overlap snugly at most points and for the major portion of the body of the glove, save at the tip :ends of the finger portions thereof and at the wrist portion thereof. The two laminations of the glove may be cemented or otherwise adhe-= sively'attached to each other where it is intended that they form a homogeneous body of one thickness. v
The construction of the finger tip ends of the glove is important. Reference being made to Figures 2, 3, 4, and 6 of the drawings it will be carefully observed that on one side of the glove, where therubber and fibrous layers of the glove material are united (Figure 2), these layers are separated, just short of the tip ends of each finger portion C of the glove A, into which they extend.
The pom-en "of'th'e' first named fibrous mate- 3 rial which has been separated from the rubber material H, in Figure 2, takes the form of a strip l2 which projects beyond the finger tip of the inner fibrous glove into which the fibrous material has been made, as shown in Figure 3. Figure 3 shows these strips reduced in length due to having been bent back, Figure 4 shows the same strips as they look from the opposite side where same are glued.
From Figure 2 it is seen that the severed strip 12 is spaced away from the adjacent rubber material ll towards the center of the finger portion C in which it extends. the tip end thereof where it is formed into a bight portion or bulge portion soon to be described. In Figure 6 is shown the width of the finger portion and how the parts look therein which are shown in Figure 2. On either side of the strip 12 are lateral shoulder portions I 4, Ma of the finger portion of the fibrous glove ll, since the width of the strip [2, as shown in Figure 6, is less than the full width of the finger portion now being explained as appears at 13. The shoulder portions I4, Ma are free to extend to wards the ends of the width of the finger portion C and they have terminals l5, l5a which are in alignment medially of the width of the finger portion.
These terminals l5, l5a of the fibrous material for the finger portion C are located at the center line of the finger portion, and abutting them are the similar terminals I Ga, lid of the other of the severed sections of the fibrous material extending into this finger portion, which is also caused to have a part thereof overlap the adjacent rubber lamination of the finished glove, but so that oppositely arranged portions thereof 16 and I! intervene between terminals l6a, Fla and the part thus attached or cemented to the rubber material.
From the circumstance that the terminals l5, l5a of one piece of the severed fibrous material and terminals 16a, Ila of the other piece have their end edges cemented to the rubber material In along the medial line of the width of the finger portion C, and that the piece having portions [6 and H is secured to the rubber side of the mentioned finger portion, and from the fact that these sets of terminals are cemented flatwise, these portions l6 and I! are spaced out of contact with the adjacent surfaces of the rubber material so air pockets l9 and 2 la are formed.
Now referring again to Figure 2, it will be seen that the bulge or loop 22 formed upon the strip I 2 is the means made use of for attaching the severed pieces of the fibrous material centrally of the finger portion C. Beyond the bulge 22 the same strip [2, of each separate finger portion C of the glove A, is further folded back upon itself and caused to overlie the adjacent rounded surface of the tip end of the rubber material I0, unadhesively. But the opposite face of this folded back portion 2| of strip i2 is glued as shown at Zia in Figure 4 particularly, so that the main strip I2 is adhesively united overlappingly to portion 2|. At this point there will be three thicknesses of material in the tip end of each finger portion, the outer layer of rubber, the intermediate surmounting layer of fibrous origin, and the third layer which surmounts layer 2| which is layer or strip l2. Inside of the loop or bulge 22 is an air pocket'l8 or 20. This bulge extends to the vertical center line of the finger tip, and against its outer face transversely thereof is adhesively attached overlappingly the It extends towards I glue is still moist a stream of fibers of approved .adverted to lie on the working side of the glove.
' It is also proposed to provide an air-pocket arrangement for the wrist portion of the glove A as is illustrated in Figure 5. For the main length of the wrist portion of the glove the two materials rubber H) and fibrous material or the like II are united, layer to layer, but at the opposite rounded bight portions thereof the fibrous material not only is severed but separated from abutting the rubber material. One of the severed pieces is for one side of the wrist portion, has oppositely disposed bulges 24 and 25 formed thereupon which contact overlappingly the adjacent rounded surface of the wrist portion. Similarly the other severed piece for the outer side of the wrist portion has similar opposing bulges 23a, 24a also overlying the adjacent rounded surfaces of the rubber material. Terminally of the severed pieces of material for the length of the Wrist portion only of the glove A, outturnecl fiange abutments are formed, the opposite abutments of one piece of fibrous material being designated 26a, 27a, and those of the other 26 and 27. They are adhesively attached fiatwise along a medial line of the width of the wrist portion B of the glove A, producing flanking bulges 27b on both pieces of material, that engage the bulges already described. From Figure 5 it is seen that the abutments space the bulges of the severed material away from contact with the adjacent rounded surfaces of the rubber outer glove material, leaving air pockets 29 on one rounded part of the wrist portion and 39 on the other.
Another way of producing the composite rubber and fibrous glove is shown in Figures 7 and 8. Here the inner parts, finger portions and cull portion or wrist portion of the rubber glove can be treated with a coating of glue, and while the material will be blown and sprayed upon the glued surfaces so as to adhere thereon, as shown in Figure 7 at 11a. The accumulation of fibers will be dense over the effective wearing surfaces of the glove. This process provides the inner fibrous lining of the glove. A more homogeneous body is given to the glove by using this process.
In operation it will readily be seen that when the fingers of the glove wearer are inserted into the finger portions C of the composite glove, and pressed'inwardly as far as they go, the tips of the fingers will engage the opposing shoulder portions 22 and 23 (Figure 2) of the inner fibrous material lining H, and since these are spaced by the rib or gusset like formation of the parts that engage the tip end of the rubber material, there will be no contact between the tip of the fingers and the tips of the rubber finger portions. In this way no matter what comes directly into contact with it, such as heated objects, ther will be no direct transmission of same to the fingers of the glove wearer. Similarly the opposing rounded parts of the finger tip ends of the finger portions of the gloves are also air-pocketed, so that the adjacent parts of the fingers are shielded efiectively from direct contact With the adjacent rubber parts.
I do not mean to confine myself to the exact details of construction herein disclosed but intend to cover all variations falling Within the purview of the appended claims.
What I desire to claim is:
1. A glove comprising an outer rubber member, inner glove member formed of fibrous materia1, said inner glove member including tabs extending rearwardly from the finger tips, and means securing said tabs to the insides of the finger tips of said outer glove member, and. providing a reinforcing lamination on one side of the finger tip.
2. A glove comprisin an outer rubber member, an inner glove member formed of fibrous material, said inner glove member including tabs extending rearwardly from the finger tips, means securing said tabs to the insides of the finger tips of said outer glove member, and providing a reinfiorcing lamination on one side of the finger tip, and means securing at least a portion of the wrist of said inner glove member to the Wrist of said outer glove member.
