HANGER FOR CABLES AND THE LIKE Filed May` 6, 1930 Patented Dec. V22, v1931 i UNITI-:D STATES PATENr OFFICE ARAY FITZPATRICK, OF EAST PALESTINE, ,OHIO
` HANGER non cABLEs AND THE Linn y Appiication mea nay e, 1930. serial No. l450,170. p
`More particularly, invention contemplates 4a novel type of electric ycable hanger which is peculiarly adapted to use in securing an electric current carrying line to a perforated rack, which may in turn be secured to a portion of the, structural work or wall'of a building, toan outdoor pole or standard, or to any other convenient'andy desirable supporting member. l
An especial object of the present invention is to provide a hangeradapted to the foregoing and other uses which may contain a standardtype of frangible vinsulatingbushing and which will positively and securely retain such bushing in placeabout the cable and. secured to thesupport in sucha wayvthat the danger 'of cracking the bushingfrom stress applied in securing the'hanger` to its support is entirely eliminated.
Another Objectis to provide a hanger which may beexpeditiously and easily applied in operative position, and which is therefore 'provided with a flange or stop in that portion ofthe hanger which contacts with the support to positively position the hanger with vrelation to the support, prevent the hanger from loosening on thesupport and permanently maintain the two in securely interlocked relation.
The foregoing and other objects and advantages of the present invention will be suiiciently apparent from the description of the v invention hereinafter, taken in conjunction with the accompanyingl drawings which illustrate, merely by way of exempliication, the invention in onepreferred form of embodiment, and in which like Lreference char- Y acters designate the same parts in the several elevation andrpartly in central vertical section showing a pair of hangers secured there- Fig. 2`is an end elevation of a hanger;` and Fig. 3 is a side elevation of the clamping members of a hanger anda vertical section of a portion of a rack, showing the method of associating the hanger with the rack.
Referring now to the drawings, the reference numeral 1 designates a rack which may consist conveniently of a metal channel having as many circular perforations 2 as the number of hangers which are to be secured to therack. l
The hanger itself consists of a pair of clamping elements 3, of malleable iron, brass or 'the like, each of which is preferably shaped to conform to one half of the eriphery of the member to be. supported. ince Ir have illustrated my` hanger in Vconnection with a substantially cylindrical insulating bushing 4, the portion of each of the clamping elements which is adapted to embrace the member to be supported is shown in the drawings substantially semi-circular in shape.
One end of said clamping element isextended radially to form a foot portion 5, and the extreme outer'end of the foot portion is provided with an outwardly extending flange 6. A second fiange` 7-isprovided on the foot 5 spaced apart from theendmost flange 6 a distance slightly greater'than the thickness of the Vperforated portion of the" rack 2. The inner end surface of each foot portion opposite the endmost flange 6 is beveled, as shown at y8, for a purpose which will presently be explained. v
The end of each clamping element opposite the foot 5 carries an ear 9 which, like the foot 5, may extend radially from the body l of the clamping element Each of these ears 9 is perforated as shown at 10, and each clamping elelnentis provided on its inner snrface, at a point adjacent to the ear 9, with an inwardly extending boss 11.
` The bushing 4 is conveniently a standard two-part yinsulator spool, having a relatively f small Vcentral bore 12 adapted to receive an electric current carrying wire or cable (not shown), andl made', according to'present standard practice, of porcelain, clay, glass -or Y other non-conducting frangible material. It Visto be vunderstood that the hanger whichk lll) forms the subject of this application for Letters Patent is adapted to support metal pipes or the like quite as well as electric lines, and it will be appreciated of course that when so used the insulating bushing 4 is not eniployed. However, I have elected to illustrate the invention in its use with electric lines, since a peculiarity of the structure of the hanger which will presently be pointed out makes it especially adapted to contain standard commercial insulating bushings made of frangible material.
It is to be understood that the word conduit as used in the appended claims is intended to include not only pipes and the like for mechanically conducting` fluids, but also wires, cables and the like adapted to transmit electrical currents. Furthermore, the hang er which is the subject of this invention is described broadly in certain of the claims as being adapted to secure a certain type of bushing to a support, and I intend such `claims to cover my novel hanger apart from the particular type of bushing which it is said to be adapted to secure, and apart from any specific type of supported element carried in the bushing.
In applying the hanger assembly to the support 2, the pair of clamping elements 3 are first associated at an angle with the beveled inner surfaces 8 of their feet 5 in contact, as shown in Fig. 3. Vhen so associated, the joint width of the foot flanges 6 is less than the width of the perforation 2 and the contacting flanged ends of the pair of feet are easily inserted through the perforation 2 in the rack 1. The two flanges 7 on the clamping elements are made of a width to limit the extent of this penetration, and when flanges 7 contact with the margins of 3erforation 2, the two parts of the bushing fl, which have previously been slipped over the cable, are placed between the clamping elements 3, and the ears 9 are then moved toward each other until bosses 11 contact.
As will be understood from the drawings, movement of bosses 11 into contacting relation will result in engagement of the inner straight faces of the foot portions and a spreading apart of the beveled portions 8. The relative sizes of flanges 6 and perform tion 8 are preferably so proportioned that when the inner straight faces of the foot portions 5 are in Contact, the outer edges of 'flanges 6 will overlap the margins ol perforation 2, to hold the clamping members and the rack loosely together. In this condition of the parts, end enlargements 13 on the insulating bushing 4; serve to prevent separation of the bushing from the clamping elements.
It Will be evident that if fastening means, such as the bolt 14 and nut 15 be used to secure ears 9 together, tightening of the fastening means will cause clamping elements 3 to undergo relative movement about the bosses 11 as fulcrums, to spread the inner straight faces of feet 5 apart and move endmost flanges 6 into further overhanging relation with the margins of perforation 2. It will be evident furthermore that such relative movement of the clamping elements consequent upon tightening of the fastening means 13 will finally result in maintaining the outer surfaces of feet 5 between flanges 6 and 7 in firm engagement with the margins of perforation 2, as shown in Fig. 1, to secure the hanger assembly to the support 1 without the imposition of any compressive force on insulator 4, so that injury cannot result to the insulator bushing regardless of the frangibility of its material or the extent to which fastening means 18 is tightened.
It is to be understood that I have shown and described my present invention merely by way of exemplification in only one preferred form of embodiment. Modifications to meet different purposes and conditions of use as well as various preferences of the designer will readily suggest themselves to persons skilled in the art to which this invention pertains, but all such modifications, to the e3- tent that they embody the principles of the invention as pointed out in the appended claims are to be deemed within the scope and purview thereof.
:D ,A l n h ead portions for urging said heads together,
- and c/ooperating fulcrum surfaces provided on each element inwardly of and adjacent to said heads adapted when the heads are urged together to spread the foot portions apart.
2. A hanger adapted to secure a frangible, conduit-carrying bushing to an apertured support comprising a pair of clamping elements adapted to embrace the bushing, each element having at one end a foot portion adapted when spread apart from the foot portion of the other element to engage the margin of the aperture in the support, a head portion at the other end of each element, fastening means associated with the head por tions for urging said heads together, and cooperating fulcrum surfaces provided on each element Ainwardly of and adjacent to said heads adapted when the heads are urged together to transmit pressure to the foot portions to spread the foot portions apart, thereby relieving the bushing of destructive pressure.
3. A hanger as claimed in claim 1, in which each foot portion is provided with a pair of 5 spaced outwardly `extending flanges ada ted to receive between them the opposlte sur aces of the support about the margin of the aperture in the support, and in which the en s of the adjacent inner surfaces of the foot por- .10 tions are outwardly bevelled.l
v 4. A hanger as claimed in claim 2, in which each of the fulerum surfaces comprises an integral boss formed on the olamplng element between the head and the bushing embracing 15 portion thereof. v
