GEORGE F. SWO RTFIGER, OF NEWARK, NEW JERSEY WALL-BRACKE 'I.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed May 1, 1905. Serial No. 258,404.

To all whom it may concern:

Be it known that I, GEORGE F. SwoRT- FIGER, a citizen of the United States, and resident of Newark, in the county of Essex and State of New Jersey, have invented certain newand useful Improvements in fall-Brackets, of which the following is a specification. This invention relates to the su porting of wires that constitute circuits for e ectric currents, and has for its object a means of supporting insulators that is neat, compact, and

easily applied, and affords ready means for taking loops from circuits.

The objects are attained by the means set forth in these specifications and the accompanying drawings, in which like letters refer to similar parts throughout the several views Figure '1 represents the bracket in its sign- I is afront elevation of the same. Fig-III shows in plan the bracket adapted for loop circuitsl- Fig. .IV is a side elevation of the triple bracket. Fig; V is a front elevation of the triple bracket. Fig. VI shows a modification 0f the bracket base, and Fig.

VII shows a cross section of the main arm.

The principal feature of this bracket is the base wlth its means for fastening it to a wall or other support. The main arm m, integral with the bracket plate I) may be extended for one .insulator, or it may be divided into branches for supporting as many insulators as a situation may require.

The base I) is elongated horizontally above the arm m' to give side-firmness to the bracket,

and is provided with elongated screw holes a, 1i. The object of making the holes oval is to afiord easy facility for inserting screws or other fastening, as, for instance, in-plugging 40 holes in brick walls with wood it might not always be convenient to-"locate'the plugs-t0 suit the screwlholes in the bracket plate, if the holes were just the size of the screws to be used. The. base b is' alsoextended below the arm m and is provided with an oval screw hole standing vertically, a fastening in I the downward extensionreducing any tendency'of the bracket to be twisted from a perpendicular.,g-On the wall side of the plate a wood or jlag-scre'w d is secured in line with the arm m. In some instances only the lagscrew and the lower screw hole would come into requisition as fastening means, the fastening in the lower hole being solely a preventive of twisting of the bracket. For some uses the u er holes a, u, might be omitted as in Fig.

Thearm m may have only a single vertical extension as at a'Figs. I, II,VI. Figs. IILIV, V, show the arm having three branches a, a,

As the arms a, a, would be subject to greater stress than the front arm a, they may be streng \ened by a web 1 Figs. III and V.

For lightness of construction the arms are made in the form shown in cross-section in Fi VII.

The vertical arm-extensions terminate in la -screw threads 0. a Iiub e of wood or other suitable material is screwed, as shown in Figs. I, II, by broken lines, in Fig. II as seen through the glass insulator. This hub is provided with insulator screw-threads. A glass insulator u' is screwed upon the hub asshown in Fig. II.

An illustration of the convenience of the thin-arm bracket is shown in Fig. III, where a 100 is takenfrom a line. The continuous line is tied to the insulator'n on the outer arm a, while the divided lines L, L, turn on the inner insulator n, n, and is easily and quickly applied.

described my invention, what I Havin desire to secure by Letters Patent,

claim an is An insulator bracket comprisin a vertical base for. attachment to the side 0 a wall, an arm projecting from said base and atlight angles thereto, the armdivided into three branches for insulators, the branches rising vertically in frontof the base, the middle branch standing farther from the base than the side arms.
