INVENTURE Patented Jan. 13, 1925.
UNITED STATES PATENT isza THOMAS H. BARNARD AND HERBERT M. TAYLOR, OF BRIGHTON, ONTARIO, CANADA.
INSULATOR-SUPPORTING BRACKET.
Application filed February 18, 1921. Serial No. 446,028.
and HERBERT M. TAYLOR, of the town of Brighton, in the county of Northumberland,
fProvince' of Ontario, Canada, subjects of the King of Great Britain, have invented certain new and useful Improvements in In'sulator-Supporting Brackets, of which the following is a specification.
This invention relates to improvements in brackets for supporting insulators for As these brackets are used inuvarying positions and are required to carryia varying number of wires,
it has been the custom heretofore to make up numerous styles of brackets according to --the position in which they are used and the number of wires to be carried thereby.
'This has necessitated the making up and carrying of a large stockof ditferentstyles of brackets both by the'manufacturers and users, some of which styleswere perhaps very rar -ly'u sed. I
.The object of our invention therefore mainly is to devise standard material which may be used to form brackets to answer all ordinary requirements, which brackets may be made up on the job as required in quick time, and which will not cost any more than the brackets now on the market.
A further object is to devise an improved method of forming the thread on the supports or points for carrying the insulators.
Further objects will hereinafter appear.
We attain our objects by means of the constructions hereinafter described and illus trated in the accompanying drawings in which- Fig. 1 is a rear view'of a piece of the material from which the bases or backs of the brackets are formed;
Fig. 2 a section through the back material and support before the nut is tightened down on the bolt; 1,
Fig. 3 a front elevation of a bracketshow ing the 'insulator supports arranged vertically;-
Fig. 4 a front elevation of a bracket showing the insulator supports arranged horizontally; and
Fig. 5 a detail showing the'method of casting the thread on the insulator support; and I Fig. 6 a front elevation of a bracket showinga modified arrangement of the tongues. In the drawings like nunerals of refer ence indicate corresponding parts in the difierent figures.
1 is the back member, preferably formed in section as a wide shallow channel. At regular intervals along its length are formed a plurality of projections 2 forming abutments directed bot-h longitudinally and transversely of the back member. These projections might simply be formed on the back by stamping, but we prefer toform the same by stamping out and bending up four triangular-shaped tongues 2, arranged so that their apexes form the corners of a square as shown in Fig. 1. These tongues, however, might be arranged to point in- -wardly as indicated in Fig. 6 with their free mediate these projections, are formed slots 5, and on the under-side of the back lines of weakness 6 are formed transversely of the back connecting the slots 5.
From this construction it follows that any length of back may be cut from the stock bar by cutting the bar from the outer edges in to the slots 5 by means of any suitable tool, such, for example, as a hack saw, and then bending the back material on the line of weakness 6, when the part desired may be readily separated.
To the back 1 we secure one or more insulator supports 7. These supports are preferably of channel shape in cross section, and the end by which the support is secured to the back is preferably closed. The support 7 has a hole 8 formed near its closed end, and the support is secured to the back by setting up a bolt 4 through the holes 3 and 8. The tongues 2 will fit tightly against the sides of the recess in the support 7 and when the nut on the bolt 4: is tightened up the tongues 2 will prevent any rotary movement of the support '1' on the back.
To prevent the nut on the bolt 4c jarring loose, we stamp up a tongue 9 adjacent the hole 8, and after the nut on the bolt a is screwed down tightly, the tongue 9 is bent over to engage the side of the nut, serving as a lock to prevent the nut from turning unless the tongue is first bent back.
The point of the support 7, for approximately l of its length, is deformed until it is of approximately annular shape in cross soj of the lead extends into these holes when the thread is being cast. The rib 11 and the lead which has entered the holes 12 are of material assistance in preventing the thread from becoming disengaged from the point of the support.
It willbe seen that the supports 7 may be secured to the back in any one of :four positions, two of which positions are shown in Figs. 3 and 4, and thatthe back may be.
made .of any length and any number of supports-maybe secured thereto spaced apart any distance which may-be found d'esirable to adapt the bracket for any particular use.
It will alsobe seen thatin some cases'three stamped up tongues 2 may besufiicient, or
even two, as-the bolt 4 would serve-to take the place of -the tongues which were omitted to keep the support from rotating. g
It will be noted from Fig. 2 of the drawingsthat the tongues .2 are stamped up in such a manner that when the support is placed in position the tongueswill first engagethe bottom of the-channel andhold the support spaced from theback 1. When the nut is screwed up on thebolt 4, to force the support tightly against the back, t-he tongues are bent over until they engagetightly in the angles between the bottom and .sidesof-the channelsupport. .lVith this tight 'jalnbing of these tongues in the angles there will be-no possibility of the support wobbling on the back.
From the above description it will be seen that we have devised constructions which will satisfactorily attain the objects of ourinvention as set fol-thin {the preamble ofthis specification. I
What we claim as our invention is:-
1. :In an insulator supporting bracket, the combination of a back member having in sulator support engaging means onits front surface; an insulator support adapted to-be engaged withsaid means in any one'ofa plurality of positions at right angles to another position to resist turning movc- .ment in :a plane parallel-to tbesurfaceof the back member, said means comprisinga set of tongues stamped out and bent up on the front-surface of the back member, "said tongues tending toresiliently hold the support spaced from theback; and meansfor securing said support to the 'back'adapted to draw} the support towards the back.
