-wire-coiling looms and for similar purposes,

in which the liability of the wire to become kinked is obviated.

Figure 1, Sheet 1, of the drawings shows a coiling-loom in perspective, or as much of it as is necessary to illustrate my invention; and Figs.- 2, 3, and 4, Sheet2,'show sectional por- I tions of the improvement.

Like letters and figures indicate like parts both in the drawings and specification.

A is the loom-standard; B, the table upon which the coils C are projected "as formed by the machine. The machine is driven, by a belt upon pulley D, having a friction-pinion; d, which acts upon the inner face of handwheel E, secured upon the shaft of one of the The wire is supplied to the coiling machinery from the stationary forms F, from which it unwinds around the enlarged heads and passes up through tubes G, which are supported loosely in stands G, as shown in Figs. 1, 2, and 3 of the drawings of Sheet 2, the upper end of said tube having collars upon it, as more clearly seen in Fig. 4, leaving the tubes free to gyrate, as shown in dotted'lines, at their lower ends around the forms F as the wire unwinds and 7 is drawn up through the tubes over the grooved rollers H and around rollers I and J to the feed-rollers of the machine. Thus the wire is supplied from these forms F or stationary spools without any rotation of the spools, as has hitherto beenthe practice, and the advantage of thus unwinding the wire is very ma: terial. First, it saves the power required to start often heavily-loaded spools as each coil is formed; secondly, .it avoids the momentum acquired by the spools, which causes them to continue to rotate after a coil is "completed,

and thus unwinding the wire and causing it to tangle in the interim between the stopping for the last and starting for the next,coil; thirdly, the strain: exerted upon the wire in suddenly starting the rotating spools causes it to vary the pitch in coiling, and especially when twowires are run together, as in the machine shown, supplied from spools oftenof unequal weight, they are very apt to icoilun like and run apart, and frequently to hop outof the web, thus rendering it necessaryto cut off and waste more or less of the imperfect coils of .wire, whereas the unwinding of the 'wire 'from a stationary form or spool exerts comparatively no resistance upon it and supplies it to the coiler at a much more even tension, thus causing it to coil much more perfectly, and consequentlywith much lesswaste of wire; fourthly,the coiling-loom can be run much faster, because there areno heavy spools to start and stop, which becomes, more diffi cult as the speed is increased and ean hardly" be done-successfully at a high rate of speed.

My improvement is, of course, as applicable 'to a machine for coiling one wire at a time as for twoor more wires. I

Having thus describ'ed'my invention, what I claim as new, and Patent, is g In a wire-coiling machine, a stationary form winding wire is conducted, that is so connected at its upper end as to permit .of a gyratory movement of the lowerend, and the said lower end adapted tomove in an orbit about the head of the spool, substantially as shown and' described.
