CARNEY, OF WIGK, WEST VIRGINIA, ASSIGNOR TO CARNEY SPLICE PRO- TECTOR COMPANY, OF CHARLES TOWN, WEST VIRGINIA, A CORPORATION OF WEST VIRGINIA WIRE-LINE PROTECTOR Application filed February 8, 1930.
This invention relates to improvements in protecting devices for cables or wire lines, the device being particularly designed for use upon the wire lines used in oil drilling.
The primary object of the present invention is to provide a protecting device which may be easily and quickly applied to a line to protect the line and the casing through which the line passes from wear.
Another object of the invention is to provide a wire line protector of a character which need not be removed from the line as the same is drawn from the well pipe to permit the line to pass over a hoisting drum and pulley but will pass smoothly over a drum or pulley with the line without doing damageto either.
Still another object of the invention is to provide an improved wire line protector so designed that it may be placed and cemented in position on the wire line, provision being made in the protector for the application of securing devices thereabout which will hold the cemented portions together until the same have permanently adhered.
The invention will be best understood from a consideration of the following de tailed description taken in connection with the accompanying drawing forming part of so this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from th salient features of the invention as expressed in the appended claims.
Inthe drawing Figure l is a view showing in side elevation the wire line protector embodying the present invention, the same being shown applied to a wire line and having holding wires wrapped thereabout to maintain the cemented edges of the protector in firm contact until the cement therebetween has set.
Figure 2 is a view in longitudinal section of the protector per se.
Figure 3 is a transverse sectional view through the protector at a point adjacent and 5'3 above the transverse center thereof.
Serial No. 427,042.
Referring more particularly to the drawing wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates generally a portion of a wire cable to which the present protector device is applied, the protector being indicated as a whole by the numeral 2.
The protector 2 is preferably formed of a good tough grade of rubber and is, as shown, of elongated tubular design and is tapered slightly adjacent each end as indicated by the numerals 3.
About the transverse center and at each end the protector body 2 has formed a recess 4 and as provided for application to the wire line 1 the protector is longitudinally split along the line indicated by the numeral 5 so that it may be opened up to receive the wire line 1 as will be readily understood.
In applying the protector device to a wire line it is opened along the split 5 and the line inserted. The edges of the split are then brought together after applying to the surfaces thereof a suitable rubber cement, and securing elements are then placed about the protecting body in the recesses 4, these securing elements may be in the form of especially prepared clamping bands or a soft grade of wire such as copper may be wrapped about the protector in the groove as indicated at 6. It will, of course, be readily understood that after the adhesive has set and the protector becomes firmly fixed on the Wire line 1 the holding wires 6 may be removed from their respective grooves so that the protector then forms a solid rubber body about the wire line. The cemented surfaces are clearly shown in Figure 3, the cement therebetween being indicated by the numeral 7.
From the foregoing description it will be readily seen that a protector constructed in accordance with the present invention of a good tough grade of rubber will effectively prevent the wearing of the wire line to which it is attached and the pipe through which the wire line passes and due to the formation of the protector and the resiliency of the material of which it is formed it will freely pass over drums or pulleys without damaging either the Wire or the pulley and without displacing the wire or causing it to jump from the pulley.
Having thus described my invention, What 5 I claim is 1. A Wire cable protector, comprising an elongated tubular body of resilient material longitudinally split through one Wall to permit of the opening of the body for the insertion of a cable, said split portion being designed to be cemented after application of the protector to a cable, and said protector having a series of circumferential grooves thereabout to receive holding elements for V A the maintenance of the edges of the split in l firm Contact, after the application of cement thereto.
2. A Wire cable protector, comprising an elon 'ated tubular body of resilient material longitudinally split through one Wall to permit of the opening of the body for the insertion of a cable, said split portion being de signed to be cemented after application of the protector to a cable, and said protector having a series of circumferential grooves thereabout to receive holding elements for the maintenance of the edges of the split in firm contact after the application of cement thereto, said body being tapered through a portion of each end to a diameter materially less than the diameter of the body adjacent its transverse center.
In testimony whereof I hereunto aiiiX my signature. SAMUEL CARNEY.
