10 Claims. 189'-31'.5)

My invention relates to improvements in so called guy guards, or protector devices employed in connection with guy rods and cables of relatively small diameter for purposes of avoiding i collision therewith by rendering such instrumentalities more conspicuous.

An object of my invention is to provide a tubular shielding device of the class described adapted to envelope the lower end of a guy or 0 bracing cable, and which is characterized by an absence of sharp corners or edges likely to cause injury to persons colliding therewith.

Another object of my invention lies in the provision of improved means for fastening a shielding member to a rod or cable.

A further object 'of my invention is to provide an improved guy guard which is economical of manufacture and which may be readily installed and removed from a guy cable or the like.

1 Other objects and advantages will appear from the following detailed description and accompanying drawings, Fig. 1 of which illustrates the device of my invention as applied to an anchor rod having a single guy cable secured'thereto; Fig. 2 shows an application of my improved guy guard to a supporting, or staying assembly employing a pair of guy cables connected to a single anchor rod; Fig. 3 is a sectional view taken longitudinally through the sheath, or guard proper; Figs. 4 and 5, respectively, are fragmentary plan, and end views of my improved protector device; 6 and '7, respectively, are sectional views taken at transverse planes indicated by the lines 6-6 and '77 of Fig. 3; Figs. 8 and 9 are views showing relatively opposite ends ofa clamping block, or body member; Figs. 10 and'll illustrate relatively opposite sides of a clamping strap; Fig. 12 is aplan view of a tapered sheath clamping element, and Figs. 13,114 and 15 illustrate a modified form of clamping block or body member.

Referring'now by characters of reference to the drawings, the shielding element of my improved guy guard consists of an elongate sheetmetal tube, or sleeve 16. The sleeve has a slotted wall opening extending the full length thereof, and the metal adjacent the opposite margins of the slot is turned convergingly inwardly to provide flanges 17. In Figs. 1 and 2 the sleeve 16' is shown disposed about the lower portion of a guy cable 18, which is secured, at its lower end, to .an anchor rod 19 as by means of the cable clamp 20, the upper end of the cable being shown as fastened to the post 21, which is representative of any object to be guyed or braced.

against the inner surface of the sleeve.

For fastening the sleeve 16 about the cable 18 and anchor rod 19, a pair of clamping devices (designated 22) are provided, one of which, by preference, is positioned on the anchor rod immediately below the anchor eye 23, and the other r of which is secured to the guy cable at a point near the upper end of the sleeve. -As appears in Fig. 2, which illustrates a pair of guy cables connected to a single anchor rod, both' clamping assemblies are positioned on one of the cables,

the uppermost thereof being the most desirable,

the other cable extending through the slot in the sleeve 1 6-for engagement with the anchor eye.

Each clamping device includes a body member which may consist of a die-cast block, designated 24 in Figs. 5, 6 and '7, or which'may be formed of heavy gauge strip metal as shown in Figs. 13 and 14, illustrating a modified form of clamping body. Coacting with one end of the body member 24, for securing the devicetoa guy cable or anchor rod, is a clamping strap 25. By preference, the central portion of the strap 25 is laterally oifset, to provide a projecting portion 26, which is adapted to cooperate with a V-shaped so groove or cable seat 2'7, formed in the end of the body member, for securing the clamping assembly to a rod or cable of relatively small diameter, as shown in Fig. '7. Where the clamping device is to be applied to a guy member of relatively large diameter, the clamping strap 25 is inverted, with respect to its position relative to the body member shown in Fig. '7, to enable clamping of the rod or cable between the grooved surfaces of the body and strap members, as appears in Fig. 6. Clamping means are provided in the form of bolts 28 which extend through apertures 29 in the strap 25, for reception in tap bores 29 of the body member. By preference the bolts 28 are provided with lock washers 30. The body member 24 is provided with rounded shoulder portions 31 which are adapted to bear solidly The flanges 1'7 of the sleeve extend into, and engage inwardly convergent faces 32 of a recess in the v body member. The faces 32 are preferably concave, as shown in Fig. 8, whereby to conform to the shape of a conical washer 33. A bolt 34 extends through the washer 33 and into a tapped bore 35 in the body member. It will appear that 0 when the bolt 34 is drawn up tightly, the conical washer is caused to press against portions of the flanges 17 overlying the concave recess faces 32, producing an arcuate crimp or deformation 36 (Fig. 4) in each flange. By reason of this crimp the sleeve member is held against endwise displacement even though the bolt 34 should become loosened.

In the modified form of clamping body illustrated in Figs. 13, 14 and 15, a strip of metal of suitable dimensions is bent to conform to an inner peripheral portion of the sleeve member, the ends of the strip being brought together and turned angularly inwardly to provide the cable seat 27a. In other respects the modified form of clamping body 24a is substantially similar to the member 24.

When installing my device on a guy cable or the like, the clamping assemblies are initially removed from the sleeveso as to facilitate their' application to the cable. After determining the proper locations along the cable for placing the clamping assemblies, the assemblies are applied to the cable at the predetermined locations and positioned relatively, with their bolts 34 parallel and partially withdrawn from the body members 24. The sleeve' 16 is then disposed about the cables by causing the cable to be passed through the slotted wall opening of the sleeve, after which the sleeve is suitably adjusted to cause the flanges l7 to'be seated against the convergent faces 32 of the body member 24. The washer members 33 are then drawn up tightly against the flanges, clamping the sleeve 16 to the cable. a

It will be readily understood that minor changes in the form and'construction of my improved guard for guy rods and cables may be made and substituted for those herein shown and I described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim as my invention:

1. In a guy guard, an elongate, longitudinally slotted sleeve of sheet metal, inwardly projecting flanges at the margins of said slot, and sleeve positioning means adapted crimpingly to engage said flanges.

2. A guy guard including an elongate sheet metal sleeve having a wall slot extending the full length thereof, inwardly projecting flanges formed at the margins of said wall slot, and sleeve fastening means disposed in the slot for clamping engagement with said flanges.

3.
