16 Claims.

This invention relates to improvements in devices for controlling static electricity, and more particularly to a means for preventing the passage of static from linemens gloves to the arms or clothing of the linemen.

It is well known that linemen who are working on live power lines have considerable trouble with static electricity. It is the usual practice for linemen to wear a pair of rubber gloves having a high dielectric strength to protect his hands. These gloves are provided with a relatively long cuff which extends up over the forearm of the wearer. Although the rubber glove aifords considerable protection against the direct contact with the high tension wires,v it has been found that due to the fact that the lineman is in contact with the wires for some considerable time, under certain atmospheric conditions, particularly when the humidity is high, a charge of static electricity forms on the surface of the glove which gradually creeps along the glove from the fingers upward toward the cuff and eventually accumulates to such an extent on the cuff that a discharge may occur from the cuff to the clothing or arm of the workman. This accumulation is decidedly dangerous, not from the aspect of,

the voltage itself particularly, but from the effect of the discharge on the reflexes of the workman. The discharge may occur with sufiicient force to cause considerable shock, this shock being sudden and at a time when the workman may possibly not be prepared for it, may cause him to jerk his arm, which is very apt to cause his arm to come in direct contact with other wires of high voltage.

Although rubber gloves with cuffs supposedly arranged to prevent this current have been heretofore known, they have not been very effective because of the inherent flexibility of the rubber and the difliculty of maintaining sufficient dielectric between the path of the electrical charge and the wearer. By the present invention I have provided a means which can be used in conjunction with any of the standard and well known types of electric gloves, which in a large measure eliminates the defects present in the prior art device, and provides greater insurance against the accidental discharge of static to the user.

Still other objects of the invention and the invention itself will become more apparent from the following description of some embodiments thereof, which description is illustrated by the accompanying drawings and wherein:

Fig. 7 is a fragmentary vertical medial section showing a method of fabricating a glove with the device of my invention built in.

Throughout the drawings, like parts have been designated by like reference characters.

Generally speaking, the device of my invention comprises a ring-shaped member adapted to have the cuff of the glove stretched over it and having a restricted portion for contact with the arms or clothing and an outwardly extending portion which extends away from the wearer and provides an effective dam for the flow of static electricity. '1

More particularly, asbest shown in Figs. 1 to 3, the device may comprise a circular member adapted to be inserted in the cuff of the glove and including a lower wall portion I which is of flared formation, the sides converging. to their smallest diameter at the end 2 which is inserted into the-cuff 3 of the glove 4. Conversely the wall flares outwardly toward the edge of the cuif as at 5, the flared portion terminating at 6 to provide a generally cylindrical body I. The body is provided with a circumferential groove 8in its periphery, the groove being separated from the portion I by a bead S and adapted to receive the rolled bead I0 formed on the edge of the glove cuff. The cylindrical wall extends upwardly from the glove and terminates in an outwardly extending circumferential flange II. The flange H extends beyond the periphery of the beadlll and away from the body of the wearer.

' The device is of a sufficiently larger diameter than the cuff to require the cuff to be stretched ,for engagement therewith. It is inserted into the cuff of the glove with the bead of the glove cuff Fig. 1 is an elevational view of myinvention, a 55 disposed in the groove 8. The glove cuff being smaller than the ring, is stretched tightly over the body 5 following closely the contour thereof.

The ring is molded or formed of a semi-plastic material of which there are many well-known in the industry today such as pyroxylin, Bakelite, Celluloid, or the like, the only requisite being that the material have good dielectric qualities and be resistant to the passage of electricity over the surface. It will be seen from the foregoing description, that this device makes it necessary to have only one set of rings for each lineman, although they may each have several pairs of gloves. The rings can be removed from the gloves and cleaned thoroughly with materials that might otherwise be deleterious to the glove and cause disintegration.

In operation the glove with the device attached is used in the usual manner which usually comprises inserting the hand and forearm into the glove with the fingers in the fingers of the glove, as is common practice. If additional fabric gloves are desirable they may be worn over the outside in the usual manner or also on the inside as is sometimes the custom.

The smallest diameter of the ring which is indicated at 2 is sufficiently large to allow the clothing of the workman to extend therethrough, but is also small enough so that there is not undue clearance between the ring and the clothing, the device engaging the clothing of the workman at the point of the smallest diameter. This has a tendency somewhat to restrict the billowing of the wearers sleeves at this point. Inasmuch as the general conformation is outwardly flaring toward the edge of the glove, the cuff of the glove is not only held out of contact with the clothing or arm of the wearer, but is held awa from the arm to a material extent. Furthermore, although there may be a tendency for atmospheric moisture to accumulate on the surface of the glove, thus in some instances providing a better passage for current over the surface, the material of the device which flares outwardly at the flange l l, provides an efiicient electrostatic dam, materially decreasing the possibility of electricity creeping across the surface. Furthermore, because it is of an outwardly flaring nature and because the clothing is somewhat compressed at the part 4 on the lower part of the ring, there is considerable distance of ter, which may accumulate on the glove, from creeping to the interior of the cuff.

In Figs. 4 and 5 I have shown another modiflcation of the device where an inner ring similar to that of Fig. 1 is used and an inner ring indicated generally at 15 is provided. In this device the outer ring provides additional protection against the contact of the gloves with the device; permits air to circulate more freely into the interior of the glove; provides further effeC-' tive means for the elimination of water; and also definitely increases the dielectric path over which electricity must travel before reaching the clothing or arm of the user. The inner ring comprises a flared body, the lower end being of smaller diameter than that of the ring I, as indicated at 2 in the ring I, and the outer edge IT being of larger diameter, all as best shown in Fig. 4. The two members are connected in spaced relation to each other by a plurality of radially disposed members [8 formed integral therewith. As best shown in Fig. 5, I have provided six of such spacers, but obviously the number of spacers is not of the essence of the invention. The spacers [8 also permit circulation of the atmosphere from the exterior of the ring I5 and the interior of the ring I. The flange I! in this instance extends materially beyond the exterior of the flange H. I have also provided a channel member around the exterior of the member H on the underside thereof, the purpose of which is to collect water and prevent the same from flowing downwardly through the air spaces into the glove.

The ring I may be of slightly larger diameter than that shown in Figs. 1 to 3 inclusive, to maintain the portion lb of the auxiliary ring sufficiently large to permit easy access of the arm. The dielectric path is increased substantially since the clothing has substantially no contact with the inner surface of the ring I, it being held away therefrom by the ring [1. This thus affords the entire inner surface of the ring I as a dielectric path over which the electricity must travel before reaching the clothing. Furthermore, the ing I! extending radially beyond the periphery of the ring H provides this additional protection against contact,

In Fig. 6 I have shown another modification of the invention where the cuff is adapted to be turned back upon itself. The ring in this instance comprises a frustro-conical body 40 pro vided at its lower edge with a circumferential groove l! adapted to receive the bead ID of the glove 4. An outwardly flared flange portion 42 is provided below the bead. The upper end of the ring is provided with a curved portion 43 which extends downward inside of the ring. As shown in the drawings, the glove is inserted through the ring and the cuff stretched over the outer surface with the bead l0 disposed in the groove 1, Any electricity which tends to accumulate on the glove surfaces has to travel over the entire inner surface of the ring as well as the cuff of the glove before it can reach the arm of the wearer.

In Fig. 7 I have illustrated a form 30 which may be substantially the same as any other glove form used in manufacturing the glove where a form is dipped into latex or similar material to provide the desired contour. In this instance, the form is provided with a shoulder 3| and a reduced portion 32 upon which a member 33 is disposed, which member is provided with an inwardly flared portion 34 abutting the shoulder 3| and adapted to receive a ring 35 formed generally as the ring shown in Fig. 1. The outer surface of the form 33 provides intimate contact with the ring from the bottom to the upper part, the purpose of which is to permit the rubber to be flared around the ring and over the edge of the flange 38. In manufacturing the gloves, the form with the ring 35 is carried by the form and the dipping process consummated in the usual manner, the rubber which is to form the cuff of the glove covers the entire surface of the ring except that in contact with the member 33. Thus the ring is molded or fabricated into the glove.

Although I have, throughout the specification, recited the gloves as being made of rubber, it should be understood that I am not limiting the invention to a glove made out of rubber, but that the glove may also be made of any suitable flexible dielectric material of which there are several on the market and usually known as synthetic rubbers.

Having thus described my invention, I am aware that numerous and extensive departures will be apparent to those versed in the art and I therefore do not desire the invention to be limited otherwise than is expressed in the appended claims.
