Int. Cl. B63b 21/04; F16g 11/06 US. Cl. 24-115 Claims ABSTRACT OF THE DISCLOSURE This application is a continuation-in-part of application Ser. No. 655,160, filed July 21, 1967 and now abandoned.

The present invention relates to a guy hook for attachment to utility line poles or the like, more particularly to the loop-retaining portion of the top side of such a guy hook.

Previous guy hook structures have comprised an upper hub portion with a horizontal passage wherein a throughbolt is inserted to retain the guy hook to the pole. A loopretaining structure comprising a hook is formed on the top of the upper hub portion. The hook portion of such prior structures usually have included a groove into which the cable loop is seated and laterally projecting structures have been provided on the loop-retaining portion above the groove to restrain upward movement of the seated loop. The laterally extending portions are generally in the shape of a T when looking at the front face of the guy hook. While these T-shaped laterally projecting arms have generally functioned satisfactorily in restraining upward movement of the loop, the arms are susceptible to breakage during manufacture, particularly in thetumbling process used in cleaning the guy hooks. Since the iron from which the guy hook is formed is extremely brittle prior to malleabilizing, the projecting arms are susceptible to break age throughout the manufacturing operations. This breakage adds considerably to scrap loss and to the costs of such guy hooks. Since the projecting arms extend outwardly some distance from the body of the guy hook, considerable care must be employed in positioning the cable loop over these T-shaped arms and into the loop-retaining structure.

One of the objects of the present invention is to provide a guy hook having an improved loop-retaining configuration for mounting on utility line poles or the like.

A further object of the present invention is to provide a simplified loop-retaining structure for a guy hook wherein the structure does not project outwardly of the outline of the hook but effectively restrains the loop from upward escape while allowing said guy or strand to rise well above the horizontal for uphill work.

Patented Feb. 2., 1971 In one aspect of the invention, the guy hook may comprise a body which is normally disposed in a vertical position when mounted on a pole with the body having an upper hub portion and a lower heel portion interconnected by an intermediate portion. The upper hub portion has a rear pole-engaging surface and an opposed forward bearing surface with a horizontally extending bolt passage through the upper hub portion between said opposed surfaces. The bolt passage is provided with a bearing surface which is engagable with a bolt received therein. The bolt bearing surfaces are substantially horizontal with one surface being on the upper side of the bolt passage adjacent the rear pole-engaging surface and the second bolt bearing surface being on the lower side of the bolt passage adjacent the forward bearing surface. Mounted on the upper side of the hub portion is a loop-retaining structure which includes a substantially horizontal groove, with the groove opening rearwardly and the outer ends of the groove diverging toward the forward face of the hub portion so that the rear corners of the top of the loop-retaining means project over the outer ends of the groove. The outer ends of the groove flare vertically to enable a seated loop to be pivoted vertically with respect to the guy hook. The widths of the loop-retaining structure, the hub portion and the intermediate portion are all equal with the top of the loop-retaining structure being substantially rectangular in shape.

In a further aspect, the upward escapement of the guy loop may be further inhibited by provision of a guard extension adjacent and rearwardly of the groove.

Other features, objects and advantages of the invention will become apparent from the following description and drawings which are merely exemplary.

In the drawings:

FIG. 1 is a front elevational view of a guy hook according to the invention;

FIG. 2 is a side elevational view of a guy hook of FIG. 1 with the lower portion cut away;

FIG. 3 is a fragmentary rear elevational view of the upper portion of the guy hook;

FIG. 4 is a top plan view of the guy hook with a cable loop indicated in dot-dash lines;

FIG. 6 is similar to FIG. 4 except that it is a modification thereof;

FIG. 7 is a front view of a modification of the inven- 'tion; and

FIG. 8 is a fragmentary view of FIG. 7.

In the drawings, like reference symbols indicate the same parts. With particular reference to FIGS. 1 to 3, the guy hook according to the present invention is generally indicated at 1 and is preferably formed of malleable or ductile cast iron. The hook comprises a body 2 having an upper hub portion 3 and a lower heel portion 4 interconnected by an intermediate portion 5. The intermediate portion 5 is generally channel-shaped at its rearward side to define a rearwardly facing cavity 6. The front wall of the intermediate portion is indicated at 7 and inclines downwardly as is seen in FIG. 2.

The upper hub portion 3 has a forward bearing surface 8 and a rear pole-engaging surface 9. There is a through bolt receiving passage 10 in the upper hub portion 3 interconnecting the surfaces 8 and 9. The bolt" passage is substantially horizontal with respect to the normal vertical position of the guy hook and includes bearing surface means 11 which is composed of a V- shaped notch. Bearing surface 11 is adjacent the rear pole-engaging surface 9 and positioned in the upper portion of the bolt passage :10. Surface 12 is adjacent the forward bearing surface =8 and in the lower portion of bolt portion of bolt passage 10, surface 12 being spaced from the bolt and not being a bearing surface. The bearing surface 11 bears against a bolt 13 as may be seen in FIG. 5. The bolt 13 has a retaining nut 14.

On the pole-engaging surface of the heel portion 4 there is provided a central tooth-like rib or projection 15 adapted to dig into the pole upon securing the guy hook to the pole as may be seen in FIG. 5. The heel portion is further provided with a number of spurs 16 for the purpose of digging into the pole to increase the resistance of the guy hook to down-sliding under the action of the cable loop 17 as shown in FIG. 5.

A loop-retaining structure 18 is formed on the upper side of the upper hub portion 3 as may be seen in FIGS. 1 to 3. The width of the loop-retaining structure 18 (FIG. 1) is the same as the widths of the upper hub portion 3 and intermediate portion 5. In one form (FIG. 4), the shape of the structure 18 is substantially rectangular.

The loop-retaining structure 18 comprises a substantially horizontal groove 19 formed in its rear face with the groove opening rearwardly. The ends 20 and 21 of the groove 19 (FIG. 4) diverge in circular fashion toward the forward face of the guy hook so that the rear corners 22 of loop-retaining structure 18 project over the groove ends. Further, the ends 20 and 21 of groove 19 are flared vertically as can be seen in FIG. 2. As also seen in FIG. 2, the rear face 23 of loop-retaining structure 18 is set back from the pole-engaging surface 19 of the upper hub portion to permit a cable loop to be positioned into the groove :19 as shown in FIG. 5.

In use, the guy hook is mounted in a substantially vertical position on a pole 24 in the manner shown in FIG. 5 and is retained in position by means of throughbolt 13 passed through bore 25 in the pole. The nut 14 is tightened so that the ribs and projections 15 and 16 become embedded in the pole to firmly secure the guy hook to the pole.

The cable loop is generally attached to the guy hook of the invention by passing one leg of the loop between the rear surface 23 of the loop-retaining structure and the pole, and then pivoting the loop approximately 90 toward a position where the cable is substantially parallel to the through-bolt, the loop then resting in the groove or saddle provided therefor.

The loop 17 of a guy cable is then positioned over the guy hook and a load is placed thereon by tightening the guy cable. The loop as seated in groove 19 passes under projecting corners 22 of the loop-retaining structure 18 so that any upward movement of the positioned loop is restrained by these corners. However, because of the vertically flaring configuration of the ends of the groove,

the loop may be pivoted in a vertical plane to approximately the position 26 as indicated by the phantom lines in FIG. 5.

The dimensional range of cable loops that can be accommodated on a particular guy hook can be increased by curving the rear face 23 of the loop-retaining structure above the groove 19 as at 30 of FIG. 6 toward the pole while allowing sufficient space to slide the loop between the pole and the loop-retaining structure. Alternatively, the width of the pole-engaging surface of the guy hook can be made wider (not shown) than its forward face so that the loop-retaining structure when looking downwardly thereon as in FIG. 4 or 6 would have its ends diverging toward the pole. In either event, there would be no transversely extending projections or arms for retaining the loop against upward movement.

'- Thus, it' is apparent that the guy hook of the present invention effectively restrains the cable loop from any upward movement which could result in escape of the loop from the guy hook during installation, use or accident. This restraint against vertical or upward movement is accomplished by extending the rear face of the loopretaining structure above the groove or saddle rearwardly to a point sufficiently close to the pole to permit sliding the loop into the groove but close enough to the pole so that when the loop is swung to a position parallel to the through-bolt, the loop cannot be moved rearwardly sufiiciently far to pass upwardly past the projecting rear corners of the loop-retaining structure. These rear corners are of the same width as the major corresponding portion of the body of the guy hook so that there are no transversely projecting arms on the guy hook.

Referring to FIG. 7, the hub portion has a groove 40 similar to groove 19 of FIGS. 1, 2. An upward extension 41 faces the groove 40 and serves to further hold a guy loop from backward movement and escapement. The form of FIGS. 7 and 8 has a single rib 42 and single projections 43 and 44. By such a construction, it is possible to cast the same by having the parting line at 45.

It is to be understood that changes in various details of construction and arrangement of parts can be made without departing from the spirit of the invention.
