Application filed January 10, 1921. Serial No. 436,401. 7

To all. whom it may concern:

Be it known that I. RIcnAnn D. KNIGHT, a citizen of the Ihiited States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Flexible Tubular Clampin ets, of which the. following is a speci cation.

This invention relates to a flexible, tubular casing or jacket of the class adapted to be readily applied .to cores of different sizes and characters, and the invention has for its object to provide such a casing or jacket which is formed of rubber tubing or the like and split lengthwise, its edges being possessed of a strong, inherent, inwardly coiling or rolling, and gripping tendency, said jacket being adapted to accommodate itself to cores of different diameters.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the ap ended claims.

n the accompanying drawings:

Figure l is a perspective view showing a section of my improved tubing coiled upon iself. illustrating its inherent coiling or rolling tendency.

Figure 2 is a perspective view illustrating a length of my improved tubular casing as applied to a wire or other cylindrical core.

Figure 3 is a pers ective view illustrating a section of my exible, tubular casing as applied to a section of tubing for the purpose of stiffening the same; also illus trating the edges of the casing as overla ping.

t is found in practice that the cord of a telephone receiver often becomes kinked, twisted or snarled causin much annoyance to the user, to obviate which a section of my flexible jacket may be opened up lengthwise and slipped over a cord which will at once straighten the kinks and the twisting.

Then again the discharge tube of-a fountain syringe oftenkinks and shuts off the flow of water. To obviate this annoyance a section of the jacket may be readily applied to the affected portion whereby the binding action of the tubular jacket forces the flattened ortion ofthe water-tube back to its norma shape permitting the free flow of water therethrough.

Also as a protecting covering for electric wires, particularly short sections of wire, which would ordinarily'have to be taped, it is onlynecessary to open up the tubing and slip it into place over the .wire, which will effectually insulate the wires and the job is done much quicker 'and presents a much neater appearance than when wound with the usual electric tape.

The following is a detailed description of one construction of flexible tubing by which these and other similar results may be accomplished My improved tubular jacket is preferably I constructed of rubber or rubber-compoun or other suitable material molded or otherwise formed into substantially tubular shape and split longitudinally as at 10, its edges 11 being so constructed that they possess a strong, inwardly-rolling or curling tendency, as illustrated in Figure 1, to normally reduce the size of the tubing so that the same will accommodate itself to fit and grip cores of different diameters. In other words the piece of tubing as illustrated in Figure 2, is shown as being applied to a core such as a piece of wire 12, the edges 11 and 13 being drawn apart to unfold the tube lengthwisepermitting it .to be readily passed onto a core and upon being released the ed es of the tube instantly contract and fit tightly and hug the core gripping the same to hold the jacket firmly in any set position thereon.

In some cases where the core is not large enough to expand the tube to its maximum capacity the edges 11 and 13 will overla' each other, as illustrated in Figure 3 an still grip and bind the core.

In some instances the outer surface of the jacket may be corrugated to render the same more attractive inappearance and also to provide a better gripping surface on the tube to be engaged by the hand of the operator.

My improved flexible tubular jacket or covering is ada ted for use on cores of grip and hug the same and .perform its functions of preventing the twist, while another section of the same piece of tubing may be applied to the collapsed discharge pipe of a syringe, its action being to remove the kinks and cause this pipe to function properly, also another section of the same length of j acketing may be applied to electric wires such for instance as those on an automobile, which would otherwise have to be Wrapped with electric tape.

Its inherent coiling or rolling action remders it possible to apply the jacket to cores of widely different sizes instead of being obliged to have a special size for each size of core to which it is to be applied.

The device has many practical usages and by its construction it may be readily applied to cores of different characters and perform a covering or jacketing eflect thereon.

I claim:

1. A tubular casing comprisingalength of flexible non-metallic tubing split lengthways to be readily applied to a core and having an inherent inwardly coiling or rolling action to grip and bind cores of difi'erent di-,

ameters to which it may be applied without the use of other binding members.

2. A tubular casingcomprisin a length of flexible non-metallic tubing spit lengthwise to be readily applied to a core, the edge of the tube having an inherent inwardly coiling or rolling action, adapted to automatically grip, adhere to and support cores of different diameters without other binding members.

3. A tubular casing comprising a length of flexible non-metallic tubing split lengthwise to be readily applied to a core and having an inherent inwardly coiling or rolling action to grip and bind cores of dif ferent diameters to which it may be applied \vihout the use of other binding members, the outer surface of said tubing being corrugated. i

In testimony ture.
