Application filed March 11, 1920. Serial Ito. 365,002.
A further object is to produce an insulator support member which may be pressed from sheet metal such assheet steel.
These and other objects which will be made more apparent throughout the further description oi the invention are attained by means ofia deviceembodying the features herein described and illustrated in the drawings accompanying and forming a part hereof.
In the drawings, Figure]. is a side view,
a portion being shown in longitudinal section, ofa support member embodying my invention; Figure 2 is a view along the line 2-2 of Figure l; and Figure 3 is an end 7 view of the device shown in Figures 1 and 2.
As illustrated, the support member consists. of a base at which may be formed of sheet metal and to which one or more insulator support brackets 5 may be secured. As shown, th base member is substantially channel shaped in cross section and may be formed from sheet metal. It is provided at a point intermediate its ends with a sheet metal mounting strap 6, pressed to conform to the surface contour of the base i andsecured thereto 10 means of rivets 7, which ex tend through tiie strap and through the web portion of the channel shaped base. As shown, the strap is provided at each end with mounting slots 8 adapted to receive or be engaged by mounting elements such as bolts or screws. The base illustrated is adapted to carry two insulator support brackets 5 and is pro vided at each: end with tenon receiving apere tures for the purpose of receiving tenons formed on the brackets; and thereby rigidly securing the brackets in place as will hereinafter be described.
As shown, each bracket is an angle or L shaped bracket, formed of sheet steel, is substantially U shaped in cross-section at its base engaging end, and is tapered to a substantially circular cross-section at its insulator supporting end. The brackets are so mounted on the base that the axis of the insulator supporting portion of each bracket extends substantially parallel to the surface of the web of the base 4. As shown the insulator supporting end of each bracket is provided with a wire helix 9 similar to the insulator supporting helix of my Patent 1,158,149 of Oct, 26, 1915. Y L The base engaging end of each lnacket is provided with integrally formed mounting tenonsll which are adapted to be inserted through the tenon receiving apertures formed in the base t and to beriveted over or upset for; the purpose of rigidly securing the bracket to the base; These tenons are preferably formed-at the time of cutting or shearing the sheet metal of which the bracket is formed and the tenon carrying edge is of such shape that itfits the adjacent portion of the base throughout its length when moved into abutting engagement with the base. With this arrangement the bracket is, in effect, seated-against the base portion when the tenons are in place in the tenon receiving apertures g'As shown three tenons are provided on each bracket, one being. lo-
cated adjacent each lower edge of the bracket and one being located at an intermediate point between the other tenons, or as shown, at the apex of the arched portion of the base engaging end of the bracket.
While I have shown each bracket formed so as to provide a U shaped section at the base engaging end thereof, it' will be apparent that the bracket maybe formed of any section which contributes to ease of manufacture and is also sufiicientl rigid to withstand the strains to which i brackets are subjected; I, however, preferably employ the tapered structure primarily because the larger base engaging end insures a more rigid and more substantial connection between the bracket and the base 4, and the tapering of the bracket occasions a saving in material by so distributing the metal throughout the length of the bracket that it is capable of resisting without deflecting such strains as may be encountered Where a bracket, such asillustrated, is utilized, a W
minimum amount of metal is employed since the base engaging portion of U shaped cross section is extremely rigid and provides an ample base engaging seat for the bracket,
whereas the POIlIIOBS Of the bracket having W less cross sectional area and of a shape less capable of resisting distortion, are subjected to less strain than is encountered at the base portion of the bracket. In other words, the area of the cross section and the shape of the bracket is varied throughout the length of the bracket to take care of the stresses usually encountered.
Each bracket shown is so located on the base 4: that the arched portion of the U shaped section is on the u per side of the bracket thereby avoiding the formation of water collecting recesses and more or 1ess protecting the mounting tenons from weather conditions. In addition the downwardly projecting parallel flanges of the U shaped portion materially stiffen the portion of the bracket subjected to the greatest cross bending stresses occasioned by the Weight of the insulator and the wires or cables supported b it.
While I have illustrated and described but one embodiment of my invention it will be apparent to those skilled in the art that various changes, modifications, additions and omissions may be made in the apparatus 1,eoe,124
illustrated, without depending from the spirit and scope of my invention as set forth by the appended claim.
What 1 claim is:
A fixture comprising a substantially channel shaped pressed metal base having tenon receiving apertures formed therein, in combination with an L-shaped insulator supporting arm pressed from sheet metal and having a substantially U-shaped edge abutting against said base, and tapered from said U- shaped edge to a substantially circular section at the outer end thereof, tenons integrally formed with said arm, projecting from said U-shaped edge through the tenon receiving apertures of said base and riveted over to rigidly secure the arm to the base.
In testimony whereof, I have hereunto subscribed my name this 9th day of March,
oriARLns L. rhinos, JR.
