RUBBER GLOVE.

Application led September 15, 1923. Serial No. 662,938.

. at Akron, in the county of Summit and State of Ohio` have invented a certain new and useful Improvement in a Rubber Glove. ofl

which the following is a full` clear. andlex act description, reference being had to the accompanying drawings.

The general object of the present invention is the' provision of a mitten or glove adaptable for use in cleansing garments of line texture. More specifically my invention is concerned with the provision of a rubber glove having a palm side and back side zones or clusters of irregularly grou )ed spurs or projections which, when the glove is worn upon the hand of the user may lie adjacent the palm side of the hand when the hand grasps a garment. A further object is the provision of a novel method for economicallyT manufacturing such a rubber' glove. Other objects of my invention will hereinafter be set forth in the following description which refers to the accompanying drawings illustratingya preferred embodiment thereof. rlhe essential characteristics are sununarized in the claim.

ln the drawings, Fig. l is a plan view of a glove made in accordance with my invention and showing the palm side of the glove; Fig. 2 is a similar View showing thc back side of the glove; Fig. 3 is a view illustrating the manner of wearing and using the glove when washing garments of fine texture; Fig. 4 is a large cross-sectional View taken sub stantially along the lines 4 4 of Fig. l; Fig. 5 shows the use of a pair of gloves.

In cleansing garments of finey texture it is usually the domestic custom to rub the garment between the knuckles and palms of the hands, using of course, water and soap as a cleansing medium. When the soap contacts with the skin of the hands, however, it acts as a lubricant and it becomes necessary to iirmly grasp portions of the arment and thus clean the arment by ru bing it between the knuck es.

Attempts have been iliade to manufacture a mitten or glove for-this purpose wherein waterproof leather or fabric was used. there being roughened surfaces provided on the love or pleces of rope or similar material, formed to give a crude representation of a washboard.

My invention contemplates the provision of rubber gloves having cleaning or rubbing surfaces irregularly formed thereon, which are formed on the gloves in such positions that when the glove is being worn for the purpose of cleaning garneients, these roughened surfaces will lie adjacent to each other, particularly when the hands are doubled into fist. form when gripping a garment. In the present instance. I form a glove of rubber b v modern approved methods whereby the palm side of the fingers of the glove are of the usual form as well as the major portion of the palm, whereby the glove walls may. be suliciently thin to permit the use thereof for other purposes than herein specilied.

Figs. 1 and 2 show a rubber glove A, which may be formed in various sizes wherebv the thumb portions B, and finger portions C may always snugly fit the wearers hand.

Upon the palm of the glove adjacent the thumb portion B, I form a cluster of irregularly arranged projections of varying height as is shown at D and a similar cluster E adjacent the little finger portion C, these clus- Iters being formed closer to the wrist portion F of the glove than to the thumb and finger portions. As shown ain this figure, the thumb portion B and the palm side and ends of the finger portions C, are not encumbered in any manner whereby the sensibility of the hand is not lost to the wearer when handling objects.

Upon the backs of the finger portion C, I

. form similar clusters or projections E which will lie immediately over the rst knuckle of each finger when the glove is worn by the user, whereby when the fingers are folded to represent a fist, as shown in Figs. 3 and 5 the clusters G are brought into juxtaposition with the palm clusters D and E. The palm side ofthe thumb portion B may have a similar zone of clusters K formed thereon.

Each set group of clusters may comprise outer rows of slight projections H and inner rows of projections J, each row of rojections being slightly greater in height than its adjacent outer row, thus facilitating the contacting or rubbing of the various projections with the surfaces of the fabric being cleansed.

An article such as I describe may be very economically manufactured by using formsv corresponding to the size of glove to be canized to the Olove Wall.

made, which forms may be dipped in a liquid rubber compound; the number of dippings depending upon the thickness of Wall desired in the glove. The clusters G, E, etc., are preferably made in molds in the form of patches of semi-cured or uncured rubber. These patches may then be applied to the form carrying the uncured dipped rubber before the form is submitted to the curing operation. The forms may then be subjected to either a gas cure or an acid dip cure, whereupon the patches become Vul- The glove may then be stripped from the form. Y

If desired, the gloves may be formed in molds in which case the clusters would then be directly molded on the rubber Wall, thus eliminating the necessity of separately forming the patches. I find, however, that the form dipping process is more economical and that the patches become thoroughly vulcanized to the finger and palm Walls of the glove and remain so throughout the life of the use thereof.

From the foregoing description of my in-y vention it will be readily seen that I provide foregoing description of my invention that a very practical glove construction is afforded which is very durable and which may be very economically manufactured, and furthermore that the rubbing surfaces are formed on the glove in such a manner as to be extremely effective in vquickly cleaning line texture'garments Without any resulting damage thereto.

It should be particularly noted that by' forming the glove on a dipping form, and then applying molded portions having irregular roughened surfaces affords a very economical method of producing thin Walled rubber articles having thickened wall zones at the places Where the article is subjected to the greatest Wear.

I claim:

A glove comprising an all rubber body having finger and thumb portions, such portions having thickened walls in zones, said thickened zone portionshaving projections extending from the surface thereof and the thickened portions being integral elastic portions of the glove body.

Intestimony whereof, I hereunto aiix my signature.

CLARENCE H. MARANVILLE.
