19 Claims.

This invention relates to clips for supporting conduit 'lines in aircraft.

One of the objects of the present invention is to provide a conduit-supporting clip which may be detachably clamped under tension on the conduit to be supported, either before or after the clip is secured to a support such as a metallic structural part of the aircraft adjacent to which part the conduit extends, whereby the installa-v tion of the clips and the removal of conduit lines from the clips are greatly facilitated, it being unnecessary to remove the screw or bolt used to fasten the clip on the support nor the clip in order to open the clip and remove the conduit, nor necessary to rely on the screw or bolt in any manner for effecting the clamping of the clip around the conduit.

Another object of my invention is to provide a conduit-supporting clip Such a-s hereinbefore described wherein a conduit-embracing cushion of compressible insulation material is carried by the metal strap for damping vibrations, electrically insulating the conduit line from the metal strap, also preventing chang and Wear of the strap and conduit.

A further object is to provide a cushioned clip of the character described in which is embodied an electrically conductive bonding strip for discharging static electricity from the conduit line through the strip and metal strap into the metallic frame structure of the airplane,

Heretofore in this art clips have been clamped around the conduit and secured to a support by means of a bolt or screw passed through apertured ends of the strap, thus necessitating a joint operation of clamping the clip on the conduit and mounting the clip on the aircraft framework. In order to remove or replace a conduit supported in this manner it is necessary to remove the screws or bolts and then remove the clips from the support.

With clips embodying the present inventionl it is possible to securely clamp the clips on the conduit before moving the latter into position to be supported on the aircraft framework, or the clips may be fastened to the framework and then clamped on the conduit, inA either case with a saving in time and labor compared to former methods.

Another object of my invention is to provide a clip of the character described in which cooperating fastening elements entirely independent of the fastening used to support the clip are subject to a quick and easy hooked engagement with one another and s0 maintained under tension for effecting a tensioned clamping of the strap and' cushion around the conduit, While being subject to being readily Sprung apart by :a suitable prying tool to open the clip and release the conduit.,

With the foregoing objects in view, together with such other objects and advantages as mayA subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of 'parts hereinafter described and claimed, and illustrated by way of example in the. accompanying drawing, in which:

Fig. 1 is a perspective view of a clip embodying my invention as installed;

Fig. 2 is a vertical sectional View of the clip as shown in Fig. 1;

Fig. 3 is a section-al View taken on the line 3--3 of Fig. 2;

Fig. l is a fragmentary perspective 0f the clip when open;

Fig. 5 is a perspective view showing the clip as. when clamped around the conduit before the clip u is mounted on the framework of the aircraft.

Referring to` the drawing more specifically, A designates a clip embodying my invention, B represents a metal structural p-art or frame part of an aircraft, and C a conduit supported by the clip.

In accordance with my invention the clip A includes a bendable and resilient metal strap I adapted to encircle the conduit C and having an outwardly extended comparatively straight and apertured end portion 2 whereby a screw or like fastening Sinay be employed to secure said end portion to the supporting structure B of the aircraft and thereby support the clip thereon.

An important improvement of my invention is the provision of fastening means apart from the fastening 3, for detachably securing the clip on the conduit in tensioned engagement therewith, either before or after the clip` is secured to the airplane structure B.

As here provided the fastening means consists of elements on the ends of the metal strap I which are subject to being readily hooked together with a suitable plier-like tool, not shown, and as readily detached with any prying instrument, also not shown, for forcing said elements apart, Said elements having tensioned engagement when Servto clamp the clip on the conduit.

One practicable construction arrangement of these fastening elements consists in bending the end portion 2 back on itself as at 2a with an aperture in said bent back portion to coincide with aperture in the portion 2 as best shown in Fig. 4. The inner end of this bent back portion is exas shown in Figs. 1 and 2 when the clip is clampedon the conduit. A portion 1 of the strap is bent back between the lugs E to lie upon the outer faceV of the strap as an abutment or gripping piece for the plier-like tool used to bring the lugs 5 and E into hooked or interlocked engagement with one another. The portion 'I alsol serves as a locking lug between the lugs 5 to prevent the lugs 6 from sliding or slipping sidewise from contact with lugs 5.

The flange 4 may be provided with an opening 8 to facilitate the gripping of said extension by the aforesaid tool during the operation of hooking the lugs 5 and 6 together.

It will be observed with reference to Fig. 4 that whenr the clip is open the conduit may be inserted therein after which by means of a tool such as aforementioned or otherwise, ,the ends of the strap I are forced into position to cause the lugs 6 to hook behind the lugs 5 as'shown in Fig. 2, thereby .clamping the clip on the conduit. The strap I is so tensioned and the lugs 5 and 6 so disposed that they may be fastened by springing the end carrying the lugs E under the flange 4 as indicated by the dotted lines in Fig. 2, the lugs 6 being forced by the spring action of the strap I into tensioned contact with the lugs 5.

It will be understood that the clip may be clamped in this manner on the conduit before or after it is secured to the structure B, inasmuch as the lugs 5 and 6 are spaced well inwardly from said screw and so arranged that said lugs and the screw may be independently operated without interference.

Depression of the end of the strap carrying the lugs E, as indicated by the dotted lines in Fig. 2, will permit of disengaging or unhooking said lug to open the clip, as shown in Fig. 4, thereby releasing the conduit. i

It is preferable to employ a cushion strip 9 or resilient material for damping vibrations in theY conduitl` lines, preventing abrasion of the line and strap and also electrically insulating the strap from the conduit line. As here shown, this cushion is provided with a T-slot I to accommodate the strap I and which forms flanges II for embracing the strap and holding the cushion thereon. This cushion is under compression when the clip is clamped on the conduit, thereby increasing the tensioned contact of the interlocked lugs and 6.

The'clip of my invention further includes a thin, flexible metal bonding strip I2, a portion I2a ofwhich overlies a large part of the conduit engaging face of the cushion while a portion I2b is clamped between the bent back portion 2a and end portion 2 and thus permanently bonded to the strap I as best shown in Fig. 2. In this connection it should benoted that the bonding strip may be welded or otherwise fixed in bonding connection with the strap.

The bent back portion 2a and the flange portion 4Hthereon afford a resilient action for the fastening lugs 5 to insure a tensioned yet secure interlocking of lugs 5 and 6 with one another and facilitate the operation of hooking and unhoob ing said lugs.

4 It is important to note that the lugs 5 are disposed well below the apertures and screw 3 in the end portions 2 and 2a, while also being well outwardly spaced from said end portions, thereby making it possible to have ready access to both sets of lugs for securing and `releasing them.

It should be noted that the clip yof my invention may be used to advantage as a harness for supporting a group of wires.

While vI have shown and described a specific embodiment of my invention I do not limit myself to the exact details of construction set forth, and the invention embraces such changes, modifications and equivalents of the parts and their formation and arrangement as come within the purview of the appended claims.
