UNITED STATES SIDNEY B. CAMPBELL, OF SAN ANTONIO, TEXAS.

WEAR PLATE.

Application filed January 26, 1923. Serial No. 615,060.

To all whom it may concern Be it known that I, SIDNEY I). CAMPBELL, av citizen of the United States, residing at San Antonio, in the county of Bexar and State'of Texas, have invented new and useful Improvements in Wear Plates, of which the following is a specification.

My present invention has reference to i Wear plates for telegraph, telephone poles and the like, and has for its primary object to prevent wear and consequent weakening of the poles incident to the strain of the guy wires and line wires that support the cables.

A further objectis to produce a Wear plate for this purpose comprising a sec tional metal annulus adapted to surround the pole at an appropriate point, means being provided for adjustably securing the sections of the annulus on the pole whereby the same may accommodate itself to poles of varying cross sectional diameters, said means also securing on the annulus plates carrying hooks to which the guy Wires are connected.

To the attainment of the foregoing and other objects which will present themselves as the nature of the invention is better understood, reference is to be had to the drawings which accompany and which form part of this application.

In the drawings Figure 1 is a side elevation of a pole showing the wear plate secured therearound.

Figure 2 is a sectional view approximately on the line 2-2 of Figure 1.

Figure 3 is a sectional view on the line 3-3 of Figure 1.

Figure 4 is a sectional View approximately on the line H of Figure 2.

Figure 5 is a view looking toward the inner face of one of the annulus sections.

Figure 6 is a perspective view of one of the lip carrying plates.

Referring now to the drawings in detail, 7

the numeral 1 designates a telegraph pole or the like designed to support thereon a line wire or cable and to be braced by guy wires.

In carrying out my invention I produce two metal plates each of a similar size and construction. The plates 2 and 3 respectively are bent or rounded upon themselves, each plate. when so arranged being greater than a semi-circle and the ends of the plates are disposed in lapping relation to produce an annulus.

Before the annulus is arranged around the pole 1, I bore an opening through the pole, and pass through said opening a headless bolt t. The sides of the post through which the bolt 4 passes are notched to provide square pockets for nuts 5, and through these nuts the bolt 4 is screwed. The bolt 4 passes through one of a plurality of spaced openings 6 adjacent one end of both the sections 2 and 3 of the annulus and through elongated openings 7 disposed longitudinally adjacent the opposite ends of the said sections 2 and 3. Each section 2 and 3 has one of its ends provided with ribs 8 which afford a biting engagement in the post or a tighter frictional engagement between the respective sections 2 and 3. Each of the sections 2 and 3 adjacent their lower ends have elongated slots 9 disposed opposite the slots 7, and a series of openings 10 disposed in a line with the openings 6.

In addition to the ribs 8 the outer ends of the sections 2 and 3 may be provided with additional ribs for frictional engagement with a. plate 11 through which the bolt 1- passes. There is screwed on the bolt 4 nuts 12 which, of course, frictionally contact with the plate 11. Each plate 11, adjacent to its lower end has riveted or otherwise secured thereto the body portion 13 of a plate which terminates in an upwardly directed lip 14. The lip 14 may, of course, be integrally formed on the plate 11, and passing through the lip carrying plates 11 and through aligning openings 9 and 10 in the respective sect-ions 2 and 3 there are the shanks of headed lag screws 15. If desired, the sides of the post 1, in a line with the lag screws may be and preferably are provided with squared recesses forming pockets for bolts 16 through which the lag screws are threaded, and also, if desired,suitable locking means may be provided for holding the outer nuts on the headless bolts 4 The guy wires are designed to be arranged on the lips of the plates and are an gularly directed therefrom to suit-able "supports. The guy wires are preferably provided with the usual adjusting means, and from the foregoing description, when taken in connection with the drawings it will be seenthait I have presented a wear plate for wire carrying poles around whichthe cable I wvires but reinforces and strengthens the pole. \Vhile I have herein set forth a satis factory embodiment of the lIYlPIOVBDlGlld; as it now appears to me, it is of course, to be understood that I am entitled to such changes and modifications therefrom as tall within the scope of what I claim.

Having described the invention, 1 claim l. The combination with a pole having a headless bolt passing transversely there through, nuts on the bolt pocketed in the sides of the pole, and additional nuts below the first mentioned nuts also pocketed in the sides of the pole; of a wear plate comprising an annulus including two companion sections having their adjacent ends overlapped and ribs at said overlapping ends said lapping ends being provided with upper and lower slots and openings respectively the upper slots and openings receiving therethrough the ends of the bolt, nuts screwed on said bolt, and lag screws passing through the lower slots and openings through the second mentioned nuts and entering the pole.

2. The combination with a pole having a headless bolt passing transversely therethrough, nuts on the bolt pocketed in the sides of the pole, and additional nuts be low the first mentioned nuts also pocketed in the sides of the pole; oi? a wear plate comprising; an annulus including two companion sections having their adjacent ends overlapped and ribs at said overlapping ends, said lapping ends being provided with upper and lower slots and openings respectively, the upper slots and openings receiving therethrough the ends of the bolt, nuts screwed on said bolt, and lag screws passing through the other slots and openings, through the second mentioned nuts and entering the pole, and plates having lipped lower ends connected to the war plate by said bolts and screws.

In testimony whereof I afiix my signature.

SIDNEY B. CAMPBELL.
