CABLE SUPPOFI.

Application am A ril 14, 1927. as no. 183,883.

' ceiving loop are suspended at intervals from a messenger wire for receiving and supporting a cable, the messenger wire being suported at widely spaced points throughout its length.

The object of the invention is to provide a hanger and a cable supporting saddle therefor of novel, ellicient and advantageous construction which will resent a broad area of supporting surface or the cable, which .dle therein easily to be applied to the mes senger wire; which will ermit the saddle to adjust itself within t e hanger in ac cordancewith the lines of the superposed cable, and which will permit of the use oi a rigid saddle with a resilient hanger without providing means to permanently attach the saddle to the hanger.

The invention is particularly useful in the regions of the poles or other supports of the messenger wire where great difficulty has been experienced in providing hangers or supportswhich will not cut the lead sheathing of the cable. The greatest strain occurs in such regions due to the sagging of the messenger wire and the cable and the hangers carried thereby between the points of support of the messenger wire. v

The invention consists in the novel construction, combination and arran ement of elements hereinafter described an claimed.

In the accompanying drawings, illus-' trating the invention,

Figure 1 is a "transverse section through a messenger wire provided with a hanger and a saddle embodying the invention, showing by dot-and-dash lines the position of the cable upon the saddle.

Figure 2 is a side view of the parts shown in Fig. 1.

Figure 3 is a top view of the parts shown in Fig. 2.

ends of the side portions of the sadd ly space the Figure 4 is a view of the ban er and the saddle showing the relation 0 the parts thereof before the hanger is applied to the messenger wire.

Figure 5 is a transverse section through the bottom portion of the saddle.

Referring to the drawings, 2 designates the messenger wire, 3 the'cable hanger, 4 thecable supporting saddle and 5 the cable.

The hanger 3 is formed of suitable wire and it includes a cable receiving loop 6 having a bottom portion 7 and upwardly extending side portions 8.

The upper end portions of the side portions 8 of the loop may be connected to the messenger wire 2 b any suitable means. The means herein il ustrated for this purpose comprises

hooks

10 and 11 which are ormed on the respective upper end portions of the side portions 8 of the hanger loop 6 and which are constructed and applied to the messenger wire 2 to connect the hanger thereto and to prevent 'disp'acement of the hanger relatively to the mes senger wire the same as the similarly designated hooks of the cable support or' hanger shown and described in my previous Letters Patent 'No. 1,373,166, dated March 29 1921, .to which reference may be had.

The lower portion of the loop, 6 or that portion thereof which receives the saddle 4 extends transversely at right angles to the messenger wire 2 and cable 5. The side portions Set the loop 6 are bent forming shoulders 9 immediately abovethe upper and the side portions 8 of. the hanger diverge above the shoulders 9 from the plane of the lower rtion of the loop 6 to

properh ooks

10 and 11 longitudinally of the messenger wire, as shown in Figs. 2 and 3.

Before the ban er 3 is applied to the messenger wire, as s own in Fig; 1, the

hooks

10 and 11 of the hanger are spaced apart,

laterally of the messenger wire, as shown in Fig. 4, and the hanger loop 6 is more open with its side portions 8 more widely separated than as shown in Fig. 1 when applied to the messenger wire. This is the normal condition of the hanger, as shown in Fig. 4; and, when the hanger is applied to the messenger wire 2, the side portions 8 of the loop 6 are sprung toward each other and the hooks 10'and 11 are caused to grip the messenger Wire by the tendency of the CIR the hanger loop 6 and the sadd hanger loop to resume its more open or normal condition shown in Fig. 4, the character of the wire forming the hanger being sufliciently resilient to permit the side por tions.8 of the loop 6 to be sprung toward each other from the position shown in Fig. 4, more than enough to permt the application of the hanger to the messenger wire without springing the hanger loop 6 beyond its elastic limit.

The cable supporting saddle 4 is U-shaped in general formation as seen in Figs. 1 and 4, for the reception of the cable 5 and to conform generally to the lower (portion of the hanger loop 6, and the sad le 4 comprises a bottom portion 12 and upwardly extending side portions 13.

The upper end portions 14 of the saddle side portions 13 are bifurcated and turned outwardly in opposite directions providin openings 15 therein for the reception of the side portions 8 of the hanger-loop 6; and the saddle 4 is provided with two laterally spaced parts or flanges 16 below the upper end portions 14 thereof, forming a channel for the reception of the lower portion of the hanger loop 6.

When herein I speak of lateral direction I mean a direction or directions lengthwise of the'messenger wire 2 and the cable 5 and transversely of the lower 1portion of The lower portion 12 of the saddle 4 rests upon the lower portion 7 of the hanger loop 6, and the main body of the saddle 4 is of plate-like form, presenting a broad hearing surface in all parts thereof which face orreceive the cable 5 or which are likely to come into contact with the cablewhile it is being drawn through the saddle or being supported thereby.

The open outer ends of the openings 15 of the saddle permit the saddle to be easily and quickly applied to the hanger 3 and permit the hanger and the saddle to be shipped separately to destinations for use; and the side walls of the openings 15 are fitted to the sides of the hanger therein in a manner to prevent any substantial lateral movement of the upper ends of the's'ides of the saddle and to permit the bottom'portion 12 of the saddle to move laterally by a rocking action over the bottom portion 7 of the hanger loop 6, the space between the saddle projections or flanges 16 being sufficient to permit such rocking action within certain limits, and the flanges 16 preventing lateral diswhen the cable isfinding its seat upon the saddle after being drawn through the same and when the cable is swayed by the action of wind or moved by other forces.

The saddle 4 is rigid and substantially unyielding, and, as previously described, the hanger 3 is resilient to permit its application to and removal from the messenger wire 2 and to cause it to grip the messenger wire. When the hanger loop 6 is in the open or normal condition, as shown in Fig. 4, the saddle 4 ma be easily applied thereto, and when the lianger 3 with the saddle therein is applied to the messenger wire 2, the side portions 8 of the hanger are sprung from the spaced relation to the. side portions 13 of the saddle 4, as shown in Fig. 4, to the close relation thereto, as shown in Fig. 1, thus closely confining the saddle 4 within the hanger loop 6. If desired the side portions 8 of the hanger loop 6 may exert inward pressure against the side portions 13 of the saddle after the hanger'is applied to the messenger wire.

When the parts are assembled, as show in Figs. 1 and 2, the side portions 8 of th hanger loop 6 extending inwardly over the side portions 13 of the saddle, prevent accidental bodily upward displacement of the saddle relatively to the hanger, and the shoulders 9 on the hanger prevent the saddle 4 from sliding in a circular direction on the rounded lower portion of the hanger loop.

The saddle 4 is preferably made from a sheet metal punching formed as illustrated and having the flanges 16 formed by bending the lateral edge portions of the main body of the saddle flatwise to extend therefrom substantially at right angles thereto around the major portion of the saddle so that the flanges 16 will have a U-shaped form following the form of the main body of the hanger and providing a 'U-shaped groove between them through which the lower portion of the hanger loop 6 extends. The flanges 16. stiffen the entire saddle and terminate before reaching the upper end portions 14 of the sides of the saddle, and the end portions 14 are formed by bending the sheet metal flatwise to extend outwardly from the upper ends of the U-shaped body of the saddle so that each end portion 14 forms an ogee curve with the main bo y flanges 16 and the u per end portions 14 of the saddle 4 are joined to the main body side portions within the hanger loo thereof so that no rough or sharp corners can come in contact with the cable at any time to mar or injure the same.
