SPECIFICATION forming part of Letters Patent No. l706,053, dated August 5, 1902. Application tiled December 4. 190]. Serial No` 84.623. (No model.)
To all wiz/0m, it muy concer-n,.-
Beit known that I, ISAAC W. I-IEYSINGER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia andv State of Pennsylvania, have inventeda certain new and useful Improvement in Means and Appliances for the Manufacture of Covered Strips of Soft Metal for Electrical or other Purposes,of which the followingis a full,clear and exact description, reference being made to the drawings which accompany and form a part of this specification, in which- Figure l is a side View of two braiding-machines, one partially behind the other,'two soft-metal strips passing through the same and receiving coatings of cement and coverings of braided fabric and thence passing'to suitable reels and afterward to receptacles from which the said strips pass to and through the double guide-passages under the, double needles and through the sewing mechanism of a double-needle sewing-machine and afterward through suitable guideways into the receptacles at the right-hand side and beyond said sewing-machine. Fig. 2 is a top view of a strand or length of said `finished material of soft metal,with its coating of cement, its covering of braid, and its row of lock-stitches through braid, cement, and metal, said length in Fig. 2 being shown as transversely divided into suitable lengths for use. Fig. 2 is a longitudinal section through'the line of stitches of b2 of Fig. 2. Fig. 2* is a cross-section of 2*L at any point where a stitch perforates the metal. Fig. Sis a top View removed from the sewing machine of the double apertured guide-passages through which the strands pass to the needles of the presser-foot,which holds the same down upon the reciprocating feed mechanism,and of the guideways through which the finished product is caused to diverge one strand from the other and fall into separate receptacles; and Fig. i is a front View of the double-needle sewing-machine.
with guide-passages to the needles and receptacles for the finished product beyond.
The lettering in all the figures is uniform. The object of my invention is to produce a long flat strip of soft metal, such as copper, lead, or some soft-metal alloy, which is first covered in the machine with a coating` of liquid cement, then a braided covering of cotton or like material applied Vto said coated strip While still wet with the liquid cement, then the covering rolled fiat to embed the same in the cement and on or in the surfaces of' the metal, and to then pass the said covered and cemented strip through a suitable sewing-machine, preferably a continuous-spool lockstitch machine, and afterward divide the same transversely into suitable lengths for use. The stitched seam thus perforates the metal through its iiat sides, and the Whole is permanently secured together, so that it may be divided into lengths, long or short, without thev possibility ofthe covering being loosened or detached from the metal strip within, while when thus out into lengths the cemented ends will prevent thecovering from fraying or unraveling, so as to expose the metal. I thus produce, by using a soft copper strip Within, a highly-insulated electrical conductor, of any length desired, dat in cross-section,and adapted to be tacked or stapled to a wall, the corner of a room, or the like, and which will'be extremely inconspicuous, and which can ,be readily cut into lengths by an ordinary pair of scissors, or the like, on account of the flatness of the material, without impairing or crushing or dislocating the coverings secured thereto. To render these in use still less conspicuous, I prefer to make the braided covering of a color to correspond,
to some extent, at least, with that of the material to which it is to be applied-as, for example, black, brown, drab, or White. When I desire, I use for the metal strip lead or other soft non elastic metal or a suitable alloy thereof,`an`d in such cases I do not employ the material for the purposes of electric conduction, but for purposes to which a cheaper material-as, for example, in short lengths suitably boxedand sold, tying up packages, fastening strands of ladies or childrens hair, stiffening garments, or thev like-the free ends of the projecting strands as covered and completed being bent over or twisted together as may be desired. The means and process of manufacture are the same in all.
If desired, I pass the braided and cemented material through a braiding-machine twice or three times before running it through the ICO sewing-machine, thus greatly increasing the insulation for electrical purposes or the bulk and softness when used for other purposes, as above described. The cement I prefer to use is a thick solution of dextrin in hot water, to which a few drops of glycerin are added to prevent drying out and cracking; but, if preferred, I use liquid marine glue, gutta-percha solution, some preparation ofindia-rubber, or any other suitable cementing solution which will firmly adhere to metal, as a mineral paint in oil or turpentine or the like.
Referring to the drawings, at the left-hand side of Fig. l are shown two braiding-machines represented somewhat diagrammatically, four spools or bobbins S S S S being shown in each; but I use eight, twelve, siX- teen, or more in practice, according to the requirements of the article. These as they rotate in involved curves around the center lay a braided interwoven covering of diagonal threads T T T T, as shown in Figs. l and 2, directly upon the metal strips m m, which pass up through the centers of the machines from the spools V4 V4 below, being bent in their ascent to pass through the cement-ing solutions V' V' in the pans V V around the rollers V2 V3 V2 V3. After passing through between the braiding-bobbins the covered strips are compressed by the corrugated feed-rolls W' WQ, two for each machine, and which are driven by the worm-gears attached to the vertical shafts at the left-hand side of the feed-rolls, which in turn receive motion from the machines below. These feed-rolls compress the covering down onto the metal strip already laden with the cementing solution andforce the cement into the interstices of the coverings of fabric and in soft metal partially embed the thread. of said coverings into the metal within. The feed-rolls are the means by which the strips are drawn up through the braiders. Passing on vertically upward the covered strips are wound around the reels A and A', one for each machine, taking one or several turns around the said reels to insure traction. These reels are operated by the preferably round friction-belts r' r', also driven from beneath. These belts are slip-belts, and having a motion in excess of that of the feed of the covered strips they will always hold the said strips taut between the feed-rolls beneath and the take-up of the reels above. When special dryness of the material is required before stitching, I sometimes reel up the covered fabric on the reels in layers until the reels are full and detach and dry/themseparately before completing the'process; but the drawings illustrate the means adapted for the continuous process, as described. From the reels A A' the cemented and covered strips enter the receptacles A2 A2, where they accumulate to compensate for the variable speed or operation of the sewing-machine. (Shown at the right-hand side of Fig. l and in front View in Fig. 4.) They may also be taken directly from the reels A' A' instead of through toepas the interposed receptacles A2. A2. The sewing-machine seen in end View in Fig. l is clearly shown in front view in Fig. 4 and the feed mechanism detached in Fig. 3.
A single braider and single-needle sewingmachine may be used, and the latter may be a shuttle-1nachine,if desired; but I prefer and use in practice a double-needle lock-stitch machine or a multiple-needle machine, one needle for each strand of material, the needles operated simultaneously by the same needlearm and the loop-forming mechanism below in the same manner. Four large spools are shown at D D' D2 D3, the threads from two of which, D D2, pass through the circular tensions to the needles N N' and the threads from D and D3 through the opposite tensions (shown in Fig. l) above and below. These machines can be driven at a very high speed and by their sudden blow strike holes in the metal strip without heating the needle andl almost without resistance, provided there is sufficient power and weight of arm and speed. H' and H2 indicate the location of the loopforming devices, which are covered up, as shown.
On the top plate of the sewing-machine I detachably and adjustably secure by the screws the double-passaged feed-guide O, having passages O2 O2 directly through the saine parallel with each other and adapted to guide two separate strands of covered material A A ct a', Fig. 3, as shown, each directly and centrally under its appropriate needleN or N'. These needles pass down between the front of the presser-foot and the rear of the passages O2 O2, the feed being located directly beneath. After passing the presser-foot the two strands of fabric-covered metal enter the divergent guideways P P', mounted on P2 P2, and overhanging the receptacles or holders B B', which I prefer to make wheeled boxes, the wheels, in whole or part, being rotating casters, and the finished covered, cemented, and sewed-through soft metal-strips pass separately into these large open boxes, in which they coil up on the lines of least resistance, so that when taken out by reversing the process' they are readily fed through a cutting-machine and divided `transversely into suitable lengths or spooled up for the market. Instead of these receptacles B B', I sometimes use reels, as at A A', Fig. l, if desired.
