GUY FITTING Filed Nov. 25, 1952 4 Fibcl. 3
GUY FITTING Frederick G. Ridgers, Hamilton, Ontario, Canada, asslgnor to N. Slater Company Limited, Hamilton, ntario, Canada Application November 25, 1952, Serial No. 322,419
1 Claim. (Cl. 287-48) This invention relates to a guy fitting.
ln guying poles for overhead lines, the common practice is to attach the end of the' guy to the upper or eX.- posed end of an anchor rod. The anchor rod includes an eye` with a built-in or a separable thimble; the eye sometimes is in part formed' by a loosely rotatable grooved roller. The end of the guy is threaded through the eye and folded or bent back, the folded portion being v clamped lto the guy as by a twin groove guy clamp and bolts.
As is known, the guy sometimes has to be re-tightened. The labour involved in so re-tightening the guy is quite appreciable and requires some measure of skill on the part of the maintenance men. The same measure of skill is also required in initially installing the fitting.
A guy fiuting should not only be such that once installed it will not easily become loose, ibut will render the attaching of the guy easy and quick, and likewise render the re-tightening of the guy easy and quick.
The objects of the invention, generally, are to provide a novel and efficient guy fitting, particularly one that is easily and quickly installed, permits of the easy applica tion of the proper tension to the guy, of the easy and quick re-tightening of the guy if required, and is also such that the fitting does not easily work loose.
A feature of the fitting of the present invention is that where used on anchor rods having grooved rollers, the titting acts to snub the roller and thereby increases the effective holding power of the connection by promoting friction between guy and roller, while the roller is tree to rotate when tension on the free or folded end of the guy is applied in the process of tightening up the guy.
Another feature of the fitting is that the free or folded end of the guy can be gripped or clamped by various methods now used in tightening guys.
Another feature is that the grip on the guy is automatic and instantaneous.
Still another feature is that the gripping or holding power of the fitting increases with the tension in the guy.
ln the drawing, wherein -is shown the preferred form of the invention,
Figure 1 is a side elevation;
Figure 2 is a bottom plan view;
Figure 3 is a top plan View, in part broken away, and on an enlarged scale; and,
Figure 4 is an end view.
Referring now by numerals to the drawings, a guy fitting made and operating according to this invention is shown as lll; the fitting is shown as serving to attach a guy to an anchor rod. The fitting may also serve to attach a guy to a pole, particularly to an eyebolt formed with an eye similar to that of an anchor rod.
The conventional anchor rod A shown is formed with an eye E rin part delined by an end portion P presenting an outer, more or less, fiat face. A groove G recessed into the portion P serves to receive and locate a portion of the guy C when operatively attached to the anchor 2,792,243 Patented May 14,
rod by the fitting. Another conventional anchor rod (not shown) includes a grooved roller rotatable in the outer end of the rod, the roller taking the place of the grooved portion P of the anchor rod shown herein.
As shown, the fitting lll includes a main body portion il, generally elongate. The body portion is extended at one end to present a portion l2 which is adapted to engage the outer end or face of the anchor rod (see particularly Figure 2), and serving as a limiting or locating stop or shoulder determining the operative position of the fitting relatively to the anchor rod when the fitting has been finally installed.
l Extending from one side of the body l1 is a hookshaped portion or lug i3 adapted to receive lengthwise the guy, that is, the main portion of the guy.
Rising from one face of the body portion and running lengthwise thereof, is an elongate tubular portion or housing l5. The bore of the housing is formed with a forward tapered or cone-shaped portion 16, and a rear circular portion i7 (see Figure 3). Within the forward portion i6 of the housing is a plurality (preferably three, as shown) of guy-engaging or gripping members or jaws 2th of conventional shape adapted to grip or release the guy as the jaws move axially within the bore 16 in one or the other direction. rEhus, the jaws will grip the guy when moved from right to left as seen in Figure 3, but will release, or tend to release, the guy when moved in tl e opposite direction.
Disposed within the bore i7 of the housing 'is a coil spring i9 tensioned between a washer 12d and a cup 2l bearing against the rearward faces of the jaws.
Releasably to lock the washer in operative position within the fitting, 'the circular bore portion Il? of the housing is increased in diameter to present a shoulder 22, and the ends of the housing are peened over as at 23 to present stops or abutments. The jaws are thus springloaded at all times, and tend to move axially to grip the guy, more particularly the folded or bent back portion CB. The gripping force of the jaws (or holding power of the fitting) increases automatically as the tension in the guy is increased.
Preferably, the rear end of the body fis slightly eX- tended longitudinally, in effect presenting a portion 26 rearwardly of the body to serve as a striking face adapted to absorb or receive blows from a hammer or the like when it is desired to re-tighten the guy. For instance, when the guy is being re-tightened by a pull on to the guy portion CB, blows are applied to the stniking face 2.6 of the body, moving the fitting relatively to the jaws and thus momentarily releasing or loosening the grip of the jaws.
In installing the fitting, the end of the guy is threaded through the eye of the anchor rod and pushed through the housing, more particularly through the space between the jaws 2li to emerge out of the housing and present the bent back portion CB which ultimately is attached to the guy C as by a conventional clip G. The body is then swung around so as to cause the hook i to engage the guy. lf at this time the guy is to be tensioned to its final tightness, a conventional come-along tool is attached to the end of the bent bach portion CB, and by means of blocks is pulled toward a similar come-along attached to the guy. As the two tools move toward one another, the guy moves through the thimble of the anchor rod and through the jaws, which instantaneously grip the guy and hold it tight.
if the guy needs retightening, the same operation is used, the momentary loosening of the jaws being effected by striking a blow on the striking face 26, say with a hammer. The body will move on the guy as the latter is being tightened until the stop 12 engages the end of the anchor rod.
When the guy has been iinally tightened as required, the guy is locked in the fitting by the jaws, and the fitting, more particularly the forward extension or portion 12 of the body, is held in engagement with the outer face P of the anchor rod. As long as the guy is under tension retaining the fitting against the anchor rod, the guy is held tightly by the jaws against longitudinal displacement.
I claim:
In combination, an anchor rod, a guy wire, and a fitting for attaching said guy to said wire, said fitting comprising an elongated generally rectangular body portion, a bore formed along one longitudinal side of said body portion, a clamping member formed along tnc opposite longitudinal side of said body portion and parallel to said bore, an anchor rod abutting portion formed on one end of said body portion and at right angles to said bore and said clamping member, spring loaded guy gripping jaws in said bore, whereby when the free end of said guy is threaded through said clamping member, around said anchor rod and back through said spring loaded jaws in 4 said bore said abutting portion on said body will mate with and abut against said anchor rod, and maintain tension on said guy, said tension being increased when desired to hold said abutting portion tight against said rod by pulling on the free end of said guy.
