I M PROVEM ENT- IN 'I NSULAT'I N G TELEG RAPH -Wl R ES. Specification formingvurt of Letters Patent No. 11,058, dated June 13, 1854. To all whom it may concern: Be it known'that 1, JOHN 1\'I.BA.TCHELDER, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in the Insulation of Electric- Telegraph Wires; and -I do hereby declare that the following is a full, clear, and exact description of the construction and use of the same, reference being had to the annexed drawings, making a part of this specification, in which. Figure I is a perspective view of the telegraph wire or conductor with its covering; Fig. II, section of the same'outhcdineUi);- Fig. I;"Fig. llL longitudinal section of the same. w The wire A A is made of copper, iron,-or .any other metal thatis a good conductor of electricity, and has upon or around it a coating, B, composed of whalebone, rubber, orbone-guni, sometimes termed hard rubber. This substance is well known in the arts, and is the same for which Letters Patent were granted to Nelson Goodyear, of the city of New York, on the 6th day of May, A. D. 1851, the claims in this patent being in the words *following: I I do not claim the heating or curing pro-1 cess, as it is termed, that having been patented by Charles Goodyear. What I do claim as my invention is. V Theco'mbiningofind'ia-rubbcrand'sulphur, either with or without shellac, for 'makin g a hard and inflexible substance'hitherto unknown, substantially as herein set forth. ' ,The coating of whalebone-rubbe'r should be about one-eighth of an inch in thickness, or of such thickness as to insure the perfect insula tion of the wire when" irrfniersed in water. The wire may be coated or covered in various ways. It may be applied in the form of a fillet-or rib- 'bon one or two inches in width and wound spirally about the wire; or a band may be cut of suitable width, and (after beingscarfed at the edges) wrapped around ithe \jwire. WVhen this is done the covered wire is subjected to the baking or curb-1g process above} re erred to, which hardens the covering and renders it one of the best of electrics or I 4 electricity. The-covered ire is;coi-led while subjected to the processof luring,and'retains this form after it is withdrawn from the heater. The coils may be straightened bypassing the wire slowly over a charcoalfire. After it is copied it maybe again coiled, and will afterward when unrolled assume'a straight line. What 1 claim, and desire to secure .byjLetters'Patcnt, is- granted to Nelson Goodyear 'nt 1e 6th day of May,-1 85l and herein referr d Signed and sealed'in the city of New Yorlc tn the 8th day of April,-1854; JOHN M. narcnnnnnn. s4; Impresence of I r Born: A.
