{Richland and state of ohio, have invented a v new and useful Insulated Rail-Support, of

which the following is a specification.

a This invention relates to an insulated railmay be used for insulating the support of varions other electric conductors.

The invention consists substantially in the construction and arrangement hereinafter set forth'in the description, and more particularly pointed out in the'clairns. A

Like reference-letters refer to the` same parts in the several figures of the drawings, in which- Figure 1 is a plan or top view of the device. Fig. 2 is avertical section of the same. Fig. 3 is a verticalsectien taken at right' an gies to the pla ne upon which the section sh own in Fig. 2 is taken. Fig. 4 is horizontal scctior. taken on the line :r x, Fig. 2.

ln the drawings the letter A designates the electric conductor to he supported, which in the fo'rm shown is a rail, and more especially a 'third rail, for carrying the current This conductor or rail rests on a cap made as a metal casting or in-any other suitable manner, and this cap is in the drawings designated by thc letter B. The cap is secured tothe rail by clamps C C, of which there are preferably two, formed alike. These clamps have stems adapted to pass through vertical apertures in the capand jaws constructed at an angle to the stems and adapted to overlap 'the rail and are preferably provided with a shoulder, as shown, to prevent them passing through the aperture in the cap. ,The stems are made longer than the apertures in the cap and are provided at their lower vertical ends with any suitable device for limiting upward movement and preventing displacement. :ind a convenient device for this purpose is shown in the drawings, which relueseut n sprl ug Cotter-piu, (designated bythe letter D.) The stems of the clamps have a free vertical movement, but are prevented from turning by any suitable means. In the drawings the stems strinse. 718,084. armani.)

of the clamp are shown as made angular in cross-section; which is found` a convenient it is evident that the same result may be aej complished in other ways.

The'cap surmounts and is supported upon an insulatingblock which'is preferably made of porcelain or vitri fied clay and may be made ofi any other vsuitable insulating material. This insulating-block is designated `in the drawings by reference-lettori@ and may extend up into thecap against the under side thereof and down some little distance below the lower edge of such cap. This block is providedwith one or -more vertical grooves G and an intersecting horizontal groove F, which latter mayexteud partially or eutirel y around the circumference, as desired. The cap-is provided with one or more inwardlyprojecting lugs or teats I, which are adapted to be insertedth rough the vertical grooves'of the block and then by turning the cap caused to pass down into the horizontal groove F, thereby effecting the locking together of the cap 'and block. A layer of cement K may be also used,- if desired, to secure the block and cap together, so as to prevent any accidental turning with reference to each otherafter they are. in place. The insulated block may itself form a support and'rest upon a crosstie or upon the ground or other support, but usually it is preferable to mount such block upon a 4standardA L. In caso. the block is mounted upon ast-andard it is desirable to form a central recess ,in the block to receive the upper end of the standard and provide the vertical walls of such recess with one or more vertical grooves N and the horizontal groove O, which latter intersects the vertical groove or. grooves. The standard may have projecting from ucar its upper end one or more lugs M, which may be made either by casting the same on. the standard or by drilling the latter and inserting apiu, as shown in the drawings. A cement filling P may be also used to connect the standard and insulating-block permanently.

By means ofthe construction Justabove described the third rail or other conductor islOO art in the details of the construction above described without departing from the princi` ple, and we therefore de not wish .te "Je 11nderstood as limiting ourselves to the'exac construction shown and-described.

What we claim, and desire vto secure by Letters Patent, is- Y l. A supportfor electric conductors, comprising a. cap and an interposed insulatingblock suitably secured together, and two clamps secured to the cap 'and having a ver.

tical play but constructed so as to be incapableof turning; substantiallyas and forthepurpose set forth.

2. A support for electric conductors, com`- prisingr a cap, a block of insulating material upon which the cap rests, two clamps carried by the cap and having means for preventing their turning, and an elongatedvertical'por- Lion to permitof free vertical moveinent; sub

stantially`as and for the purpose set forth.

3.In a support for an electric conductor, the combination with an insulating-support, of a pair of clamping-lugs having jaws to overlaplv theccnduc'or end vertical portions passing through apertures in the su ppo rt, and

having au angular crs-secton, whereby such clamps are permitted a vertical move- `ment and are prevented from turning; substantially as and for the purpose set forth.

4. In a support for electric conductors, the combination of a cap provided with clamping-lugs adapted to clamp such cap to the rail or other conductor, a block of insulating material supporting the same, the cap being provided with one or more lugs and theblock of iusulnting material with one or more vertical grooves and a horizontal groove,`whereby such vclump and block of insulating material.-

insulating-block, adapted topermit the insert-tou of 'the lugs anu' retain the parts npositou when connected; su bstux'itielly asa'nd for the purpose set forth.

6. In a third-rail support, the combination of s standard provided with projecting lugs near its'top, a block of insulating'niaterial provided with a. -vertical' recess on its under side having one or more vertical grooves formed in the walls ot the recess end a -ho,r-

zontal grooveinsthewall ofjrthe same intersecting the vertical groove or'groovesf and said block also provided 'near'itsuppere'nd with one or more vertical groove: upon'its outer surface, and a horizontal groove intersecting the same, a cap resting on the top of such insulating-block and extending around a portion' of' the sides'thereof, and said cap provided with e tent or teats adapted to be inserted through. the vertical groove or grooves and pass into the horizontal groove, and clamps secured to thecap and-having an angnlnr cross-'section vand o f slength sufficient to alle w vertical playin the apertures formed in the cap for the reception ,of the vertical portions of the clamps; substantially as and for the purpose set forth. .Y

In witness whereof we have hereunto set our hands, this 19th day of May, 1899, in the presence of the subscribing witnesses.
