WIRE-SUPPORTING ARRANGEMENT Filed Oct. 51, 1956 United States Patent 2,923,510 WIRE-SUPPORTING ARRANGEMENT Kurt R. Walch, Philadelphia, Pa., assignor to General Electric Company, a corporation of New York Application October 31, 1956, Serial No. 619,537 6 Claims. (Cl. 248-68) in bundle or cable form.

The invention is specifically concerned with the type of Wiring cleat which comprises a wire-supporting surface against which the wires are secured by suitable fastening means. Prior -designs of this general type of which I am aware have been subject to a number of disadvantages. For example, in utilizing certain of these prior designs, it has been necessary to resort to unduly timeconsuming operations in order to secure the wires to the cleat. Additionally, with most of these prior designs, if the fastening means hasbecorne slightly loosened, the wires could become easily detached from the cleat, thus defeating the supporting function of the cleat. Moreover, few of these prior designs have readily lent themselves to being used ywith a variety of diierent types of.

fastening means, and, hence, it has been necessary to stock a variety of cleats where dilferent types of fastening means are to be used. Still further, many of the prior designs, when incorporated into a wiring assembly, have consumed an undue amount' of space and have not lent themselves to neat and compact assemblies inasmuch as they have projected laterally outward from the supported wires in an unsightly fashion.

Fig. 9 is a cross-sectional view along the line 9-9 of Fig. 8. Y

Accordingly, a general object of my invention is to provide a simple and inexpensive wiring cleat which is largely free from the disadvantages set forth above.

Another object of my invention is to provide a wiring cleat which is so constructed that wires can be quickly secured thereto and thereafter prevented from becoming detached even if the wire-fastening means becomes slightly loosened.

`Another object is to provide a wiring cleat of the above nature which is concealed beneath the wires it supports and thus consumes a minimum of otherwiseuseful space'l and 'allows for a neat and compact wiring assembly.

In carrying out my invention in one form, I support one or more wires upon a panel or the like by means of a Fig. 10 is an elevational view of wiring cleat.

Referring now to Fig. 1, a plurality of insulated wires 12 are shown formed into a bundle and supported upon a panel or base 14 by means of a wiring cleat 15 constructed in accordance with one form of my invention. The cleat 15, comprises a mounting foot 16 which extends parallel to the upper surface of the panel or base 14 and is secured to the panel by suitable means, such as, for example, by a screw 17 threaded into the panel. Other securing arrangements such as bolts or welding can equally well be used for this purpose. Carried by the mounting foot 16 is a body portion 18 of strip-like form which is shown laterally offset from the mounting foot. This body portion 18 extends generally parallel to the upper'panel surface and is spaced therefrom.

As can be seen in Figs. l and 2, the body portion 18 of the cleat is provided with corrugations which form. alternate ridges and furrows extending transversely of the body portion on'opposite sides thereof. The wires 12 extend transversely of these ridges and furrows and are anchored against the upper surface of the body portion 18 by suitable fastening means, such as lacing cord 20, which is bound tightly about the wires 12 and the body portion 18. With the lacing cord 20 located in one of the furrows 21 on the lower side of the body portion and thus interlocking with the furrow, as shown in Fig.- 1, slippage of the cord along the length of the cleat is eifectively prevented by the adjacent ridges, even if the showing a modified form cord should become slightly loosened. So long as the wiring cleat which has a mounting foot secured against a ysurface of the panel. Carried by the mounting foot is a body portion which extends generally parallel to the surface of the panel in spaced-apart relationship thereto.

The' body portion is corrugated to provide alternate ridges and furrows extending transversely thereof. The supported wires extend transversely to these ridges and furrows and are anchored against one side of the body portion by fastening means which encircles the wires and the body portion and interlocks with at least one of the furrows on the other side of the body portion.

For a better understanding of my invention, reference may be had to the following specification taken in connection with the accompanying drawing, wherein:

n Fig. 1 is a side elevational View showing a wire-sup-v porting arrangement which utilizes a wiring cleat con# such as 17 sometimes cord 20 remains reasonably tight, the bundle of wires is firmly anchored to the cleat and effectively prevented from moving in any direction with respect to the'cleat.

Assuming that the cleat rst has been secured to the panel 14, anchoring of the wires 12 upon the cleat can be a quick and simple operation with the illustrated cleat. For example, all that is involved is iirst forming the wires 12 into a bundle, resting the bundle upon the upper surface of the body portion 18, then Winding the lacing cord 20 about the bundle and the body portion with the cord located in the furrow 21, after which'the`lacing cord is pulled tight and suitably tied. The space provided between the body portion 18 and the panel 14 greatly facilitates the winding operation inasmuch, as it allows the assembler to slip the cord beneath the cleat from its front end 22 as he winds the cord about the bundle and cleat.

The laterally offset relationship ofthe body portion 18 with respect to the mounting foot 16 not only serves to provide the above-described spacing between the panel 14 and the body portion 18 but also serves to protect the insulation of the lower wires 12 from being abraded by the head of screw 17. Because the heads of screws develop sharp burrs' adjacent their tool-receiving slots, they are capable of seriously impairy ing this insulation if the wires are allowed to bear rmly against such heads. The offset between my mounting foot 116 and body portion lllS locates the wires l2 in such a position that their insulation does not contact `the' head of Yscrew `17* with sufficient pressure to allow damage/toy suchTinsulatio'n. If desired, the offset can be of sufficient extent to insure that the wires are maintained completely out of contact with the screw head.

It will be apparent that the above-described laterally offset relationshipv betweenthe foot 'lr6 and the body portion 13 is 'also advantageous in those applications in which the foot is arc-welded to the panel. Such 1aro-welding tends to produce sharp edges proiecting upwardly slightly from the foot 16, and the offset acts to maintain the supportedwires out of damaging Contact with such edges,

FFrorn Figs. l and3 it will be apparent that the insulated wires vlfare generally in alignment with the cleat 15 along its length, and thus the cleat is largely concealed e beneath such wires when viewed from above. This relationship not only contributes to a neat wiring assembly but also contributes to a highly compact assemblypin'asmuch as the cleat does not project laterally outward from the bundle of wires to consumel otherwise-useful space.

It should also be apparent from Figs. 1-3 Athat my cleat 1'5 is capable of supporting any number of wires of the same or varyingsize so long as the inherent mechanical strength of the cleat or the fastening means is nt overtaxed. In this same regard, it is to be noted that my cleat is capable of supporting only a single insulated wire if need be. l

An important advantage of ymy cleatis its versatility in lendingitself to use with different typesof wire-fasten.-

ing' means. vFor example, for larger bundles offvvir'es 'or for cables, stronger and more complex ties 'of lacing 'cord can bereadily used for anchoring lthe bundletothe cleatlS; In this regard, reference may be had to Fig. 4 in which thev lacing cord 20 is shown bound about-the bundle andthe cleat in separate spaced-apart locations.- As a; further example, reference 'may be had to Fig-5 in which the co'rd is shown bound abOUtthe bundl'eiand cleat alongthe entireV length of the body portionV ofthe cleat. `In any case, when cord is used as fasteningv means,

kat vleast a portion of the cord should be located'in-at least one of the furrows on `the underside of the cleat in order to vprevent the` cord from slipping with respect tothe cleat as described hereinabove. Y i

Figs. 6 and 7 further illustrate the versatility-of the cleat in lending itself to use with different types off fastening means. Here, the wires are anchored to Vthe yripper surface of the body portion 18 by means of a resilient 'the cleat and threaded into Yship to the' panel L18 serve the desirable purpose of permitting the free passage of air between the ridge areas upon which the wires 1,2 are supported. This tends to maintain the insulating cover ofthe wires 12 free from moisture inasmuch as the air acts to car1y away from this region a large portion of the moisture formed by possible surface condense-.tion on the cleat. The grooves themselvcsalso act to drainsuch moisture aWay from the insulation.

Another" important purpose ofthe furrowsV on` the upper surface of the body portion ltll is that they allow the cleat easily to be formed from a blank of uniform cross-section, as by a simple stamping process. Since the furrows on the upper surface register with'the ridges on the lower surface, and vice versa, Vthe body portion of the cleat is of a generally uniform cross-section along its length, and this allows/the stamping operation to be considerably simplified. Y

Wliere it is not practical or desirable to mountv the Wiring cleat l5 directly against the panel or base 14, in the manner shown in Fig. l, the desired spacingbetween the body portion liti and the panel 14 can be obtained even without the offset relationship between the mounting foot 1-6 and the body portion. For example, in Fig. 10 the mounting foot 1'6 is provided with a stud 45 secured to the panelV 14. Y This stud supports the'mounting foot i6 in spaced-apart relationingbetween the bodyY portion- '18 and ther panel even though the mounting foot 16y and the Vbody portion 18 are disposed inlessentially the same plane. A look nut 471 threaded on the stud 45 bears against-the panel 14 to prevent the cleat fromy being accidentally shifted with re- Y spect to the panel.v

While the wiring cleat 15 is preferably formedof Y a plastic compound. These latter yconstructions would provide additional insulation between the supported Wires and the metal panel or base 14.
