Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF INVENTION [0001] This invention relates to work gloves which are used for handling metal which is often coated with oil, and in particular relates to gloves having an oil or solvent resistant barrier. BACKGROUND OF THE INVENTION [0002] Liquid impervious gloves consisting of a synthetic plastic shell formed to cover a hand are not suitable for applications where the glove is used over a prolonged period of time since they do not breathe or transmit air and they are therefore uncomfortable and hot. [0003] While gloves made of fabric and having a protective covering such as a plastisol fused to the palm and fingers will be more comfortable and will provide some resistance to liquid penetration, the plastisol covering can become slippery particularly when exposed to oil and other lubricants. It is therefore common practice to simply use knitted cotton fabric gloves and to discard them when saturated. Some additional protection may be obtained by wearing an inner fabric glove and an outer fabric glove and discarding the outer glove on a periodic basis. [0004] An object of this invention is to provide a glove which will have an outer surface with good grip properties while providing some liquid resistance and comfort. SUMMARY OF THE INVENTION [0005] In accordance with this invention there is provided a glove having an outer shell made of fabric, a plastisol coating on the fabric disposed on an interior surface of the glove to cover a palm portion and front portions of the glove, and an inner comfort liner covering the plastisol coating. [0006] The invention also provides a method of fabricating such a glove in which an outer shell made of fabric is slipped over a hand former, the hand former is brought into contact with a bath of plastisol to coat the fabric shell on a palm portion and front portions of the glove with a plastisol coating, the hand former and the bath are separated, the plastisol coating is allowed to dry until it is still tacky, an inner comfort liner is applied to the tacky plastisol coating to produce a glove assembly, the glove assembly is heated to cure the plastisol coating and the glove assembly is removed from the hand former to bring the inner comfort liner into an interior of the glove while exposing the fabric outer shell adjacent the palm portion. BRIEF DESCRIPTION OF THE DRAWINGS [0007] In order that the invention can be more clearly understood, reference will be had to the accompanying drawings showing a preferred embodiment of the invention, as follows: [0008] FIG. 1 is a perspective view showing a first step in a method of fabricating a glove in accordance with the invention in which an outer fabric shell is slipped over a first hand former; [0009] FIG. 2 is a perspective view showing the fabric shell positioned on the hand former; [0010] FIG. 3 is a schematic side elevation showing the hand former of FIG. 2 being lowered into a plastisol bath; [0011] FIG. 4 illustrates the hand former partially immersed in the plastisol bath; [0012] FIG. 5 illustrates the hand former separated from the bath of plastisol and showing the plastisol coating on the fabric shell; [0013] FIG. 6 illustrates the hand former being rotated to bring the plastisol coated palm portion of the glove in an upward orientation; [0014] FIG. 7 is a perspective view showing the application of a comfort liner to the plastisol coating on the glove; [0015] FIG. 8 is a perspective view showing the glove assembly consisting of the fabric outer shell and a comfort liner applied to the plastisol coating; and [0016] FIG. 9 is a schematic perspective view showing a second hand former disposed opposite to the first hand former with the fingers placed end to end for inverting the glove assembly over the second hand former. DESCRIPTION OF PREFERRED EMBODIMENT WITH REFERENCE TO DRAWINGS [0017] In accordance with a preferred embodiment of the invention, the fabrication of a glove 20 will be described which has five pocket portions for receiving respective digits of a hand. It will be understood that the glove 20 may have other configurations and could for example have two such pocket portions to form a mitten or other configurations, as desired. The glove indicated by reference numeral 20 in FIG. 9 is an assembly which is fabricated using an outer shell 22 made of fabric (FIG. 1). The fabric outer shell 22 is preferably a circular knitted cotton fabric glove which is seamless and is commonly used as a glove in itself. However, for purposes of this application, the fabric shell is treated to enhance its liquid resistance properties. As illustrated in FIG. 1, the fabric shell 22 is first inverted and then slipped over a first hand former 24 which is a hollow aluminum casting having the shape of a hand and which is mounted at a flanged end 26 to a conveyor (not shown). Arrow 28 indicates the relative movement of the outer shell 22 onto the hand former 24. Such hand formers 24 are well known in the art and will be available in a number of different hand sizes for right and left hand configurations. As can be seen more clearly from the side elevational view of FIG. 3, the hand former 24 has an arm portion which is somewhat inclined relative to the palm portion so that the glove outer shell 22 is only partially immersed when brought into contact with a bath of plastisol 30 as indicated by arrow 32. The plastisol bath 30 consists of a liquid which when dry forms a liquid impervious coating on the fabric shell 22. While thermoplastic materials such as acrylonitrile butadiene rubber (also known as nitrile) are preferred, the plastisol coating may also consist of polyvinyl chloride, polyurethane, or latex. [0018] While it is preferred to coat only the palm portion and front portions of the outer shell 22, in order to maximize the comfort and breathability of the glove, other orientations of the hand former 24 may be used if it is desirable to immerse the entire outer shell 22 into the plastisol bath 30. As can be seen more clearly in FIG. 5, only a front portion of the outer shell 22 has a plastisol coating 34 when the hand former 24 is removed from the plastisol bath 30 as indicated by arrow 36. The plastisol coating 34 will adhere to the fabric outer shell 22 and form a unitary layer which joins the individual fibers of the knitted cotton fabric comprising the outer shell 22 while still leaving the cotton fabric bare on the opposing side of the outer shell 22. [0019] After removal of the hand former 24 from the plastisol bath 30, the plastisol is allowed to run off the outer shell so that any excess material will be captured by the underlying bath of plastisol 30. The hand former is then rotated as indicated by arrow 38 in order to orient the hand former with the palm facing upwards so as to provide ready access to the plastisol coating 34. While the plastisol coating 34 is still tacky and is not yet fully cured, usually within two minutes after separating the hand former from the bath of plastisol, a felt comfort liner 40 (FIG. 7) is applied to the tacky plastisol coating 34 as indicated by arrow 42. The felt comfort liner 40 is previously trimmed from a sheet of suitable material which preferably consists of a polyester non-woven felt but which could equally comprise any other fabric such as cotton or polyester blends that will absorb perspiration during use of the glove 20. It will be understood that the comfort liner 40 will in use be adjacent to the user's palm and the front surface of the user's fingers and will desirably also provide a cushioning layer to protect the hand.
