.Patented Nov. 22. 1864.
Mw f@ 'the fibersI of the sliver and without J. E. CHASE AND JOSEPH TOY, OF SIMSBURY, CONNECTICUT.'
lereejoveer :N SAFETY-Fuses.
Specification forming part of Letters Patent No. 45,1110, dated November 22,1864.
To al whom, it may concern:
Be it known that we, 3J. E. CHASE and 'Josera TOY, of Simsbury, in the vcounty of Hartford and State of Connecticut, have -inventedI a nevir anduseful Improvement in SafetyFuses; and we do hereby declare that the following" Iis a full, clear, and exact description thereof, which will enable those fuse constructed'after our invention.Y Fig. 3 Vrepresents a piece of safety-fuse constructed after our invention patented lJ une 30, 1863.
Similarletters of reference indicate corresponding parts.
This invention consists in covering thebody of fuse, in making water-proof safety-fuse, with a covering made of ber when it is inthe con-v dition known as' sliverJ Theletters a in the several figures represent the strandsvvhich form the tube for the reception of the gunpowder or other fuse composition, Vand b is the4 covering-yarn which is Wound spirally about the strands c to keep them together, so as to form them into aV body. `When the fuse is so far completed, lit is coated with varnish or other suitable material in the usual way. XVe then cover the fuse with a sliver of cotton, jute, or other fibrous material, laid longitudinally along its sides without twisting I winding them about-the body of the fuse. Thismay' be accomplished in any suitable way,` one convenient and suitable -way being to pass the sliver, as it comes oii' the cardinglmachine, through a trumpet-shaped tube in such a man` ner as that'the sliver shall be spread'over the/ sides of the interior of the tube, thus yforming a tube of sliver,` and then passing the fuse through the same, and thereby causing it to be covered by the iibers of the sliver as they both 'emerge from the smaller end of thel trumpet-shaped tube, at which point the cord orl yarn d is to ,be wouudabout the sliver to stance used for coating it, `so that the central vstrands containing the powder shall be fully lfabric is made of a lap of cotton or other fibrous material inclosed between two warps, to which they are united by sizing. It iscut into strips or tapes, which are wound spirally around the fuse. The lcovered fuse is then coated with varnish to make it Water-proof.
Among the advantages which our invention described in Figs. lfand 2 has over afuse constructed like that shown-in Fig. 3 are the following: The coating c is applied longitudinally andyparallel with thev sides of the fuse. Its strandsare independent one of the other, not being twisted together o'r formed into a fabric. It does' not contain any starch or other sizing, the eii'ect of the starch being to resist the absorption of the varnish. It will absorb the varnish more quicklyand readily than any other coating, and will take a largerquantity at-a single immersion, thereby saving the necessity of many successive imm'er'sions;y It
'will not be so `liable to crackin cold weather or in cold situations. It will not spring away from the sides of the fuse when bent, as in the ease of a coating formed of a. tape whose edges will open when the fuse is bent out o f a straight line.
Any fibrous material'before it is spun and 'when it is in a condition' similar .to sli-ver can be used to'forrn the coating c'.
Having thus described our` invention, vwhat we claim as new, 'and desire vto secure `by Letf ters Patent in safety-fuses, is-
Inclosing the bod-y of the fuse withinl a 'cov-,
ering of loose bers in the condition of sliver or its equivalent, substantially as and for the purpose above described. A
