PATENT OFFICE c OHIO BRASS COMPANY, OF MANSFIELD, OHIO, A. CORPORATIONOF NEW JERSEY CONDUCTOR SUPPORT Application filed .Tune 27.
Our invention relates to conductor supports and particularly supports for a trolley wire, and the process of producing the same.
The object of our invention is toprovide a support or ear which may be built up from several parts into a unitary device, thereby permittingv the various parts of the ear to be made from material particularly suited to that part, as, for instance, the lips or portion which grip the trolley wire may be made of rolled or drawn sheet material; the sup orting portion may be made of cast or drop forged material, or it may be of rolled material witha separately formed supporting member secured thereto. t
Our invention resides in the new and novel construction, combination and relationof the various parts herein described and shown in the accompanying drawing and in the steps covering the process of producing the am In the drawing Fig. 1 is a side view of one form of our invention with a portion in section.
Fig. 2 is an end view of Fig. 1.
Fig. 3 is a plan view of the lip portion of ourvinvention as formed from sheet material. j r
Fig.4 shows the methodof uniting the lip portion and supporting web portion, j
,Fig. 5 shows another form of supporting portion formed of two separable parts, a web portion and a boss portion.
Fig. 6 is an end view of Fig. 5. Fig. 7 is a sectional view of Fig. 4 taken on the line 7-7. g
In the preferred embodiment of our invention we provide a lip portion 1 formed of sheet material, as in Fig. 3, and composed of any material. desired such as hard orsoft rolled or drawn copper, brass, bronze, aluminum or-a ferrous metal, and is provided with.
slots or cut away portions 2. The lip portion lis formed into a U-shapedmember of such size as to receive and fit the trolley conductor, after which the lips may be formed about the conductor by a workman installing the device.
In Figs. 1 and 5 are shown two-forms of supporting members for' the lip portion 1.
1929. Serial No. 374,073.
The form 3 shown in Fig. 1 is ada ted a; be
character and securedto the web portion by means of rivets or screws through the parts.- It will be appreciated that our construction 7 passing entirely permits of a wide variation in the various materials fromwhich the device is constructed, as',for instance, the portion 1 may be made of hard drawn copper and the portion 3 in Fig. 1 maybe made of cast brass or bronze of. any composition desired, or may be of a cast or forged ferrous material. In Fig. 5 the web 4 may be formed of sheet steel or any suitable non-ferrous material, while the boss portion 5 maybe of a castferrous or non-ferrous material, or forged.
' Referring to Fig.5, the web 4 is formed as shown with the plurality of projecting lugs .6 adapted to bepositioned within the recesses 2 of the lip portion, and the web 4 of or MmsrrnLn, onro, ASSIGNORS To rim Fig. 1 is providedlwith. the same projecting lugs 6 to be received inthe openings 2 of the lip portion, and these parts having been assembled, the parts are placed in an inverted positionas shown in Fig. 4 and the projecting portions of the lugs 6 are then fused to form .an integral'alloyunion with the adjacent I portions of the lip-portion 1 by means of an electrode '8.
adjacent parts land 4or 4, and if additional metal is required, it willzbe applied in the form ofseparate metal rods.
The parts may also be united by means of the oxyacetylene flame, also well known to those skilled in the art, but we find that the electric arc process is more desirable." 7
By making the openings 2 a little wider than the projecting lugs 6,the fused metal will flow downwardly throughthe space between the lugs 6 and the sides of the openings 2, and by placing a carbon mold on the outside of the parts at the point of weld and hav-.
ing a slight recess therein, this fused metal can be caused to form a fillet 9 which tends to brace the web and lip portion against a side strain. 7 I i the iorm shown in Fig. 5, the lower faces 10 of the member 5 maybe undercut so as to rest upon the up'perpor'tion of the lip portion 1 and thereby tend to brace the lip portion and web 4" against relative side move ment. .7 v
It will be apparent tha-t'we have provided a built'up supportior a trolley wire of a plurality of parts united to each other and the I method of forming such device and in which the use of a large range of materials is provided. Having described our im; r
