Abstract: 1,117,750. Pipe brackets. H. ZIMMERMANN. 29 Nov., 1965 [1 Dec., 1964], No. 50554/65. Heading A4B. [Also in Divisions E2 and F2] A hanger of the kind which, when in use. is fastened to support 2 and includes a holding device for holding a pipe or cable comprises mounting means engageable with the support and a telescopically adjustable portion having two relatively slidable members 10, 11 one of which is an inner member and the other of which is an outer member, one of said members carrying the holding device, the said members having engagement means consisting of a single projection or several projections co-operable with apertures or recesses, one of said members being deformable so that the engagement means is rendered operative to prevent said members from any further relative movement after adjustment. In each construction the holding device comprises three shells 3, 4, 5 the shell 5 having out-turned tongues which are snap engageable with slots in the shells 3 and 4. In the construction shown in Fig. 1, both the outer and inner members 10, 11 of the telescopic adjustable portion 6 each have two walls and the shells 3 -and 4 are integrally formed with the walls of the outer member. One wall of the outer member is provided with apertures 12 and one wall of the inner member 11 is provided with a projection 13 which is engageable with any one of the apertures 12; when the two members are in the desired position the two walls of the members 10 are forced towards each other by the use of pliers to prevent disengagement of the projection from the selected aperture. The member 11 is formed with mounting means 7 which are engageable with inturned flanges 9 of a rail 8 which is secured to the support 2. The means 7 are entered through a gap between the flanges 9 and the member 11 is then rotated through 90 degrees to engage the means 7 with the flanges. In a second construction, Fig. 3, the inner member also has two walls and these are integral with the shells 3 and 4; the outer member 10 is provided with means 7 which abut the support 2 and it also has two walls, one of which is provided with a plurality of apertures 12 with which a projection 13 of the inner member is selectively engageable; to secure the inner member to the outer member a screw 17 is provided which also serves as the mounting means, the screw passing through the inner member 11 and deforming the wall carrying the projection 13 in so doing and engaging into the support 2. The wall of the inner member carrying the projection 13 is provided with a slot 16 for facilitating the deformation thereof. In a modification of this construction the member 10 is provided with a resilient tongue and the member 11 has the apertures 12; the tongue enters the interior of the member 11, which is hollow, so/that its tip which forms a projection can engage the desired aperture 12 and the screw 17 forces the tongue into the aperture. In a further modification, Fig. 6, the member 10 is provided with four tongues which enter the interior of the member 11; each of the opposite walls of the member 11 is provided with two rows of apertures 12 and projection 13 at the tips of the tongues are engaged with the apertures by distorting the walls of the member 11 inwardly. In a further modification of the Fig. 3 construction, instead of a screw 17 which enters the support 2, a threaded bolt is used, this engages a threaded hole in a mounting means 7 which is passed between flanges of a rail 8 and rotated through 90 degrees to attach the portion 6 to the rail which itself is secured to the support 2. Embodiments are also described having apertures in each wall of the member 10, but in which the member 11, instead of having tongues, has the projections 13 at the ends of its walls, the members 10 either being expanded to engage the projections with the apertures by means of a screw or, alternatively, the member 10 is crushed by means of pliers. Constructions are also described in which, instead of using apertures in the member 10, this is instead provided with corrugations in its walls which are engaged by similar corrugations in the walls of the member 11, the two members being forced into engagement by a screw in the interior of the member 11. There is also a construction described Fig. 8, not shown, in which the member 11 is provided with a tongue having a web-like projection at its end which is engageable with a selected aperture in the member 10, the member 10 being crushed to secure the projection in the aperture. In this construction the end portion of the member 10 is corrugated and is intended for building into a support.
