(Crais-6s) 3 Claims. 1
This invention relates to a sectional block-like support for holding in place in aircraft a group of conduit lines, with said lines clamped on cushioned seats to dampen vibrations and protect the lines against wear, this type of support being exemplified in United States Letters Patent No. 2,227,528 issued to Paul W. Adler on January 7, 1941.
One of the objects of this invention is to provide a sectional conduit supporting block of the character described in which the sections are made of plastic, wood, metal or other rigid and relatively stillE material and provided with flanges to facilitate the mounting thereon of yieldable cushion strips of rubber, synthetic rubber or the like, thereby making it possible to use but a small amount of the strategic cushioning material as compared to the thick block-like cushions heretofore used and at the same time insuring a more secure holding of the cushion strips on the rigid sections of the block.
A further object of my invention is to provide a conduit-supporting block of the character described which will permit of the advantageous use therein of extruded cushion strips which are substantially C-shaped in cross section, this type of strip having become a standard product in the art for use on conduit clips of the type shown in United States Letters Patent No. 2,215,283 for Line supporting clip, issued to Paul W, Adler on .A
September 17, 1940, thereby making one form of cushion strip suited to blocks of the type here shown as well as to said clips.
Another object of my invention is to provide an improved body construction for conduit supporting blocks of the character described wherein the sections of the body are each made of like half sections of sheet metal stampings or molded sections of plastic material to facilitate and reduce the cost of the manufacture of the blocks and preform the cushion retaining flanges thereon.
A further object of my invention is to provide a conduit-supporting block of the character described in which each section has an I-shaped cross section to reduce weight and provide flanges Fig. 1 is a perspective view of a conduit-supporting block embodying my invention;
Fig. 2 is a sectional view taken on the line `2--2 of Figl; l
Fig. 3 is a fragmentary longitudinal sectional view taken on the line 3-3 of Fig. 2;
Fig, 4 is a fragmentary perspective view of one of the sections of the block with the cushion removed therefrom;
Fig, 5 is`a perspective View of a modified form of this invention;
Fig. 6 is a cross sectional view taken through Fig. 5;
Fig. 7 is a fragmentary longitudinal section taken on the line I--l of Fig. 6;
Fig. 8 is a fragmentary sectional view taken on the line 8-8 of Fig. '7;
Fig, 9 is a fragmentary exploded perspective view of one of the two-part sections of the block as shown in Figsl 5 to 8 inclusive, showing how the two parts are vfitted together to make a section of the block.
As shown in the accompanying drawings a conduit-'supporting block embodying my invention is lmade up of a pair of opposed elongated and rigid body sections I and 2 having complementary conduitreceiving channels 3 in opposed faces thereof which latter as well as the channels are lined by cushion strips 4 of yieldable elastic material such as rubber or synthetic rubber so that the conduits 5 will be embraced by and clamped between said strips when said sections are clamped together by bolts 6 and nuts 1. The bolts are passed through openings 8 in said sections and also provide for securing the block as a whole with the conduits clamped therein to a structural part of the aircraft, such as the part' 9 here shown.
The present invention deals more particularly with the construction of the body sections I and 2 and the particular association thereof of the cushion strips d. Each block section is of an I- shape in cross section and made of a rigid plastic material or wood or metal. This formation provides desired strength with a relatively thin section of light weightvwhich may be readily and inexpensively stamped, cast or molded. It also provides flanges I0 projecting laterally from opposite longitudinal edges of the web portion I I of each section. The flanges I0 on the opposed surfaces of the sections I and 2 as shown in Figl 4, follow the curvature of and project laterally from the channels 3, thus forming portions of the walls of the channels.
The cushion strips 4 are substantially C-shaped in cross section and comprise a main body strip 4a adapted to lie upon the fiat surfaces between the channels 3 and also line said channels from one end of the block to the other; side flanges Ib extending at right angles to the body strip to lie against the outer edges of the flanges IIJ, and flap-like flanges 4c projecting inwardly from the flanges 4b and parallel to the strip @a so as to'lie against the inner surfaces of the flanges Iii with their longitudinal edges against the webs II.
It is now seen that the cushions may be slipped endwise onto the flanges I throughout the length of the sections I and 2 and will be securely held thereon by means of the flanges 4b and fac. With this arrangement the cushion strips form a cushion between the body sections I and 2 also embrace the conduits so as to effectively dampen lvibration in the conduits and prevent wear thereof. This method of afxing the cushion makes it unnecessary to cement or ,otherwise fasten the cushion .strips and makes it possible to readily replace a worn or damaged cushion in the eld. j
If desired the edge or face of the section which is opposed to the structural part 9 of the aircraft may be fitted with a cushion I2 of the same construction as the cushion 4 as shown in Figs. 1, 2 and 3 so as to cushion the block against said structural part. In this connection it is noted that the flanges I0 on the outer edges or faces of the sections I and 2 are straight and that the cushion strip I2 may be fitted thereon in the same manner as the cushions 4 are fitted on the flanges at the opposed surfaces of the body sections.
It is now seen that in having the block body made of half-sections having the flanges I0 along opposite sides of its longitudinal edges as here provided, the sections may be made with relatively thin webs and ianges of non-strategic material such as wood 0r plastic or of thin sheet metal, yet will have requisite strength and rigidity and provide for a most convenient use of flanged cushion strips which are securely held in place by the flanges on the sections. Moreover the flanged construction makes it possi-ble to mount the rubber cushion strips on the outer edges as Well as the inner or opposedv edges of the body sections as.
the occasion demands. Furthermore, the flanges on the inner or opposed faces of the block sections provide for relatively long cushioned seats axially of the conduits and complementary channels 3 as said flanges form portions of the walls of the channels which provide in effect a series of sleeve-like conduit-embracing seats securely holding the conduits in place.
In Figs. 5 to '7 inclusive I have shown a modified form of the invention which embodies all of the features of the rst described form and is of the same construction except that the sections I 4 and I5 forming the body of the block are each made of two channel shaped parts that may be cast, stamped or molded. More particularly this form of my invention lends itself to being conveniently and inexpensively made of sheet metal stamped in the formation best shown in Fig. 9.
In this form the two channeled parts making I4 up each body section are designated I6 and are spot welded together as at I'I to form a complete I-shaped half section of the block.
As all other parts of this modified form are of the same construction as those shown in Figs. 1 to l inclusive, they are identified by the same reference numbers plus a prime character, for example, the cushion strips are il', the bolts 6', nuts l', flanges Ill', and so on.
This modified form is employed in the same manner as the first described forni and its stamped out formation of two channeled parts for each half section. of the body of the block and the I-beam shape of the sections makes for requisite strength with a low weight and but a small amount of body material. The half circular rib-groove formations I8 which form the bolt holes afford effective reinforcement along with the flanges per each half of each body section.
While I have shown and described specific embodiments of my invention I do not limit myself tothe exact details of construction set forth, and the invention embraces such changes, modifica tions and equivalents of the parts and their formation and arrangement as come within the puru A View of the appended claims.
