To all whom it may concern: l

- Be it known that I,W1ILLIAM 1 Honsr- .MANN, of Brooklyn, in the county of Kings and State of New York, have invented icert/ain new and. useful Improvements in the Construction of Cables for TelegaphicPurposes; and I do hereby Ideclare and .ascertain the" said inven-` tions,ireferring to the accompanying drawings,

in' whichl .v

Figure'l'is'a generaloutline of the arrangementand disposition ofthe apparatus` on board a ship when the cable is to be submerged. Fig.

2 is a vertical section of 'a-'reservoir enlarged.

My improvement in this portion of my invention consists of a modo of making and lay# ing the cableand,is as follows:

A wire, of copper or other godconductor of electricity, wound .on'a spool, or reeled or coiled conveniently, as shown in the drawings at a a, is placed in any couvenientpostion, from whence the end of the wire passes through a proper scouring apparatus, such as sand-paper or other materialrand thence through leather polishers, as at b, by which all oxide on the surface is removed. The bright metallic wire thus eleanedis drawn along a line at 'the j unction of two inclined planes, as at c, (see Fig. 2,) down which a qnantityof dissolvedguin-lac is caused' to flow, by which the wire receivesaperfect coating. Afterpassing this coating apparatus the wire is drawn through a heated cyliuderoroven,l

c', which equalizes the coating somewhat, and thence the wire runs between two rollers at c,l where a covering of cloth is'applied to it, or other brous covering. The material, being wrapped around-th'ewire by grooves'in the rollers, adheres tothe coating thereon. From thence I convey the wire through a'napparatus ot c, containing gum-lac dissolved in a pureas the best for the reservoirs for gum-lac, pitch,

or rosin composition, is as follows:

Iform areservoir or kettle, (see Fig. 3,) which if itis to be heated, is made double and heate g e' flhvrsroNNo. 2.

` specification formingpalrt oFLetters dated September'ilil,185i); Reissue Al',34"3,dated y 4. 1"', '.Scpterberl p 'by steam, as in other steam-heat;-

ers.` Thisreservoir is hun grou trunnions or lugs a', Lsee. lFig. 3,) through whichthe steam en-l ters, so as not to ,be tipped or canted 'by the rolling of theA vessel. At the axis of this reservoir the wire .above nam-ed 1s made to pass through a casing surmounted by a double-inf.; f

clined plane, table, or hopper, which feeds thel coating material to the'wire as it passes through the hopper, ybein g supplied fromfthel reservoir.

The wire then runsthrough an apparatus at d Y lfilled with rosin mixed `with suiicient tar to make it pliable, or with a similar compound of the resinous gums. This is preceded by a coating of muslim, tape,paper, or other fibrous ma terial, or gutta-percha, o1'. india-vxubber, and it is then passed through a wrappingguide ap paratus, as seen at e, whicliis a conical tube that wraps the material around the wire. -v

The operation of wrapping niay'be completed by a` pring-fork, f, that embraces it'. A second c ting ofthe'resinous compound and anA other tapemay then be added. or more, if found advisable; Then the conductor, thus insulated,

may be joined to another, .similarly formed and coatedtand the two bound'together byayarn woundtfrom a bobbin or spool around them i1 amannergwell known and used for icoverin g boni ett-wire and'such like articles. This is done at g,'and ath a second yarn may belaid in thev opposite direction, crossingth'e' 'irst. I give no particular description of this apparatus for covering wireas there are many varieties well. known. The conductor orconductors thus iusulated has one or more stout iron wires joined it, as all protectors heretofore made have done.

The cable thus formed is conveyed overboard either at the stern .of the vessel, as shown in the drawings, or at the side or other most suit able point of delivery.

In passing overboard the cable should enter a kettle of melted .tar and rosin compound at;

m, down through Athe bottom o'wliieh il'fpasses,l

as clearly shown in the ligure. An elastieinouthed opening at that point prevents any more of the compound escaping than is suicient to properly eoat the "cableasiit descends thence into the water.

The opening above named at m is "governed, by a rope, o, by which the opening can be oontraeted or expanded.- The kettle is double and heated by steam.

By making the cable as it laid I avoid all v injury from handling.

Having'tlius fully described my improvements, what Ielaim anddesire to secure in this portion of `my patent reissued, 'isyl'. Forming the cable herein described by the apparatus, `substantially as herein set forth, consisting of coating reservoirs and wrapping apparatus, Ste., or their equivalents.

, 2.-".llie final ,reservoir m, for coating a telegraph-cable just before it enters tbe water or round, substantially as and for the purposes eseribed.- i i 3. Manufacturing the cable at tbe time itis laid, when found advantageous so to do, as above specified.
