IMPROVEMENT IN SUPPORT-ERS EQR TELEGRAPH-WiRES.

Specification forming part of Letters Patent No. 6,779,1dated October 9, 1849.

To all whom it may concern: 1 Be it known that we, L. R. LIVINGSTON, J.

l J. BoGenN, and CALVIN ADAMs, of Pittsburg,y

thereof, reference heilig had to the accompa-A nying drawings, making a part of this specication.

The nature of our invention coiisistsiri'couiiiing the .shank'of a telegraph-wire holder orV supporter iii a protecting socket or cavity by means of some suitable insulating substance placed, while in a fused or softened state, in the socket around the shank ot the wire holder or supporter; or, if preferred, the insulating substance can be first placed in the socket or cavity and the shank ot' the wire holder or suppoi ter inserted therein while it (the insulating substance) is in a soft state. The socket that incloses the insulating substance that surrounds the shank'of the wire holder or sup porter, serves to .protect the insulating subsubstance from external injury and from the injurious eii'ects ot' moisture, aud'also from the eli'ects of sudden changes in the temperature of the atmosphere. Y I

1n the accompanying drawings, A, Figure l, represents a section ot' the upper portion of a post surinounted by a metallic protectingcap, E, and an insulated Wire-supporting cap, B, and having pendentl insulated wire-holders G G contined in inverted sockets or cavities in the arms H M L projecting from the sides of the post. The protecting-cap E may be con fined to the top ot' a post by a screwshank de sceuding from its center into the post, or by a rim descending from its periphery and einbracing the top of the post, or by any other suitable means. From the center ot the top of the cap E there rises a supporting-shank, D, which is confined within the socket in the cap B by the insulating substance b, thereby causing the cap B to be perfectly insulated and supported. A telegraph-wire is conned to the top of B in the manner represented in the drawings; or it may be confined to the top or sides of the cap in any other appropriate manner. An inclined riin, O, projects from the base of the cap B of suicient width to conduct the water that may fall upon it clear ot' the sides ot' the post.

H is a metallic arm let into and confined lo the post, lhaving a metallic cap, F, cast upon oirotherwise secured to its outer extremity, in the cavity within which cap the shank ot' the wire-holder G is confined and insulated by the insulating substance b. j

L is a wooden arm secured to and projecting from 'the side of the post, having asocket formed in its lower edge, in which the shank of the holder G is insulated and coniined by the insulating substance b. We shall sometimes castuaii iiirertednconical.opening or openi cavity. in the outer end" of Y'the metallic arms" for the reception ot the insulating substance b and the shank of a Wire holder inclosed therein, as represented in the drawings, at the outer end of the metallic arin M. We shall pro tect the insulating substancein this open cavity by a cap, s, fitting over its top and confined thereto by Alugs descending from its under side into the insulating mass, as shown iii the draw-- ings.

In Figs. 2 and 3 and in thek other drawings we represent four different methods of confining the telegraph-Wire to the holder, either ot which or any other that'inay be deemed preferable may be adopted.

The cavities or socketsl for the reception of the insulating substance for contining and insulating the Shanks of the wire holders or supporters therein must be of such a form as to securely retain the insulating substance therein, and the shanks of the wire-holders must be of such a shape as to prevent theirbeing drawn out of the insulating substance.

For insulating and confining the shauks ot' the wire holders or supports within their protecting sockets or cavities we shall employ glass or brimstone; or we shall employ a coinposition of brimstone, rosiu, and gum-shellae, in about equal parts as to bulk, or any other insulating substance that may possess a suffii cient degree of strengthl and tenacity.

Fig. 4 in the accompanying drawings represents the manner in which we shall make use ot' the metallic arms U that haveheretofore been employed in the old and imperfect methods of insulating and supporting te1egrapli'= 2 cm2/a wires in our improved'and more perfect manner of insulating` and supportingA them. We shall do this byyinsulatil'lg and securing a wiresupporting cap, V, upon the vertical portion ofthe arm U by means ot some suitable insu-I lating substance, b, placed Within the cap and i around the vertical portion of U, substantially in the manner hereinbet'ore described. The Wire may be secured to the side of the cap V 1n the manner represented in the drawings, or

` by any other that may be preferred.

When glass is made use of for conlning a shank Within a metallic socket or cavity both the shank and the socket must be raised to a high temperature before placing the fused glass within the socket and around the shank'.

Fig. 2 in the accompanying drawings repre- -sent-s a manner of confining the telegraph-Wire to the pendent holder Gby means of two hooks, r r, branching outward and upward from-the bottom of the holder, the'wire being sprung or bent into such a forni that it can be dropped into the hooks and pass at the side ofthe holder, by which means the Wire will be securely retained in its place.

Fig represents a manner of retaining the telegraph-wire Within a single suspendinghook at the lower end of the holder G by 'means of a link, s, through Which'a bight ofthe Wireis passed previous to placing it upon the hook.

Fig. 5 in the accompanying drawings repre- What We claimas our invention, and desire to secure by Letters Patent, is-

1. The uniting and confining the shank ot' a pendent Wire-holder or the upright portion ot' a supporter within a protecting socket or cavity by means of some suitable insulating substance placed While in a fused or softened state within the socket or cavity, and occupying the space between its interior surface and the shank of the holder or supporter, substantially in the manner herein set forth, not intending, however, to limit ourselves to the particular forms orpositions of the insulated wire holders and supporters referred to above, the essence of our invention as herein claimed being the production ot' an insulated connection between thewire-supporters and the holders by placing the insulating material while in a fused or softened state within a socket o r cavity in the one and around the shank of the other.

2. r)She manner of confining the telegraphwire to the holder G by means ot'anotch or hook thereon and/a loop or link, s, combined there- Witlnsubstantially as represented in Fig. 3.
