8 Claims. (Cl. 2-169) This invention relates to an improved glove construction and particularly to a glove of the fourchette type.
In making gloves one of the big problems is to provide sufiicient room in the fingers in order that the glove may be comfortably worn. Gloves in general are classified according to the manner in which this is accomplished. One such method is to insert fourchettes between the palm finger section and the back finger section of the gloves to provide the required room. This type of glove is generally referred to as the fourchette type and this invention is primarily directed toward the fourchette type of glove.
This invention is more particularly directed toward a fourchette type of glove wherein the seam is bonded by an adhesive or cement, rather than joined by stitching,
To my knowledge there is no glove on the market bonded at the seams by an adhesive although suitabl cements for this purpose have long been known. One of the main reasons why no glove cemented at the seams has been marketed, is the many problems involved in the manufacture of such a glove and this invention solves one of the major problems. In joining the fourchette to the front and back sections by stitching, the type and shape of the fourchette is not important where the only problem is one of stitching around the finger tip and in between the fingers at the base to avoid buckling, wrinkling and the like around the curved portion of the fingers since the operator of a sewing machine can readily overcome this dimculty by the simple means of gathering in the fourchette at the proper places. This cannot be done where gloves are joined at the seams by a cement since such gloves are not manufactured by a device like a sewing machine. Furthermore sewing is a slow proces compared with the process of making my glove as will be hereinafter fully described.
It is therefore an object of this invention to construct a fourchette in such a manner that it may be readily joined by cementing to the palm and back sections without wrinkling and buckling and which lends itself to being assembled commercially, rapidly and economically, which would not be possible if the existing type of strip between the front and the back portions of the glove.
It is a further cbjectof my invention to provid a reversible glove using my type of fourchette which is a major improvement in the art of making reversible gloves since it permits the use of cements for bondin the seams of the glove which was heretofore not possible. Reversible gloves have appeared on the market from time to time but they have never been successful since all used stitching in the seams. It is well known in the glove art that the stitching is the weakest portion of the glove and no matter how strong the material is, th glove quickly wears out and must be discarded since the seam is the first to wear out and therefore there has been no object in having a reversible glove since the purpose of a reversible glove is to enable the wearer to obtain more service from the glove by wearing it on either hand. By the use of my glove the seam is the strongest part of the glove and for the first time a reversible glove becomes a commercial reality. By actual test the seams on my reversible gloves are more than ten times stronger than a glove wherein the seams are stitched.
The bonding of the seams by a cement permits a less bulky seam and the bond may be made between the various sections of the glove so that it does not need to be turned after the seam is bonded. It is the present practice in making gloves that the seam is stitched inside out, which is an expensive and time consuming operation.
Any cement as long as it has good bonding properties for joining the seam may be used. Many of such cements are available on the market today. However I prefer to use a cement of the plastic type, either of the thermoplastic or the thermosetting type. Some cements require little or no heating to form a bond while others like thermoplastic materials require heating but in all cases it is usually desirable to apply heat to speed up the bonding process.
Some of the thermoplastic materials which I prefer to use because of their rapid bonding on heating include: rubber hydrochloride, vinyl; resin, plasticized polyvinyl chloride, vinylidene chloride, and various cellulose derivatives such as cellulose nitrate. However, it is also within the scope of my invention to use the following thermoplastic materials: polyvinyl acetal, casein and, its derivatives, cellulose acetate, polystyrene,
polyvinyl acetal, ethyl ,cellulose, polyvinyl formal," methyl methacrylate resin, polyvinyl butyrals, cellulose acetate butyrate, and vinyl chlorideacetate copolymer, etc.
Among my preferred thermosetting materials are vinyl resin formaldehyde, polyvinyl acetate; emulsions, and phenol formaldehyde resins.

a...d.istance. greater thantheextent of notches in order. torprovide sufficient. material for coating amass? site edges of the fourchette 'are'made for the portion ofthe fourchette lying at the base between the fingers. It is not necessary that any material be removed by these incisions and it is preferred that no material is removed so that the material in between the incisions can overlap on to the front and back sections to provide a bonding area as will be more fully described in connection with Figure 4. Incisions ll, I2, [3 and M in Figure 2 are positioned in the glove construction in Figure 1 as indicated by the same numbers.
The glove illustrated in Figures 1 and 2 was made in the following manner: The front and back sections 1 and 2 and the fourchette 3 were cut by the usual stamping machine using proper dies and the three sections l, 2, and 3 were coated along the seam edge using a thermoplastic material. It is preferable for ease of handling to allow the thermoplastic cement to dry before assembling. The three sections were then laid in a mold and this operation involves only about 15 seconds. The glove in the mold was then heated by induction heating at a temperature around 200 for about 40 minutes. The glove was then allowed to cool in the mold for about 30 seconds and then the mold removed. It might look from the above that it takes 40 min utes to make a glove commercially but this is not the case since hundreds of these molds may be placed in the same induction furnace at one time and by the use of only one cutting machine, one assembling station and one induction furnace a glove may be turned out about every 15 seconds which in itself is a remarkable improvement over previous methods for manufacturing gloves.
A glove made in this manner by actual test has a resistance to shear of over 500 pounds per square inch which is over times the shearing strength for gloves made by stitching.
- Referring to Figures 3 and 4, numeral l5 in Figure 3 illustrates incisions angling towards each other and towards the center of the fourchette and is one type of incision which may be used and has the advantage of providing a strong bonding area. This is partly shown in Figure 4 by the same numbers. In Figure 4 fingers I 6 and I1 constructed in the manner shown in Figure 1 have the front and back sections forming a seam area as indicated by thenumber l8. The spreading of the sections l5 by the incision also provides a large bonding area. A large bonding area is not necessary for a force exerted by pulling of the fingers l6 and i1 apart since the continuous fourchette itself resists that force. However a force exerted by pulling apart the front and back sections would tend to pull the seams apart if it were not for the bonding areas as indicated by the numeral l5. Therefore I have provided a construction of the glove which makes it possible to have the shearing strength heretofore mentioned.
Figure 5 is a perspective view of a finger which tapers at the tip both from front to back and from side to side and, this type of finger especially in a dress glove, is often desired. However this type of taper in the fingers makes it important to use notches of the type shown in Figure 6. The notched portion between numerals l9 and 20 must bend around the finger shown in Figure 5 between l9 and 26 so as not to form wrinkles during the glove construction. This is accomplished by first cutting the fourchette in a slow bending are or curve between points 2| and 22 and a hyperbola type of curve has been found best suitable for this purpose. The notches 22 are then cut in opposite sides along the slow bending curve. The notches cut in this manner eliminate all wrinkling and buckling when the glove is assembled and manufactured commercially by using molds, presses and the like where individual attention cannot be given by the operator to each finger tip as can be done if the glove were stitched.
