MEANS FOR NRA1?]?Il l'G STBANDS AROUND EACH OTHER.
Specification of Letters Patent.
Patented 'lFeb. 13, 1917.
Application filed October 17, 1916. Serial No. 126,115.
7 To all whom it may concern:
Be it known that I, EMORY J. Llrrs, a
citizen of the United States, residing at Fountain Hill Borough, in the county of Lehigh and State of Peniisy lvania, have invented certain new and useful Improvements in Means for Wrapping Strands Around Each Other, of which the followingfis a specification.
In a co-pending application of Lloyd H. Lipps and myself for a patent for a method of uniting textile strands means has been disclosed for wrapping two strands around each other so as to put a so-called preliminary second-time twist therein which would keep the strands together and thus avoid the use of the usual flier in the ensuing second-time twisting or spinning operation, the same consisting of a member over which the strands were drawn in frictional contact therewith and which presented a smooth surface extending crosswise of the line of draft of the strands, and means to effect relative movement as between said member and the strands crosswise of said line. The said member as shown had the form of a cylindrical bar, the round shape of which caused appreciable surface to be presented to the strands so as by frictional action to insure the desired wrapping during the relatively lateral movement. In practice I have found that it greatly improves the wrapping action if in coincidence with the crown of the wrapping a groove or other space be provided in the wrapping member so as to extend longitudinally of its acting surface; with such a space present the tendency of the strands to lie side by side and not roll over each other when the tension reaches a certain degree as the result of the wrapping and consequent twisting already produced is eliminated, so that the wrapping may continue to a much further extent than where the space is absent.
I now proceed to a more particular eX- planation of my invention, reference being had to the accompanying drawing, wherein,
Figure 1 is a side elevation, partly in section, of a wrapping means including the present improvement, that part of the means for drawing the strands lengthwise which onsists of the receiving spool appearing in side elevation; and
Fig. 2 is a front elevation of the wrapping means, the strands in this case appearing magnified.
(Z is the spool on which the strands are wound. The latter are assumed to be supplied from a source, such as another spool, below spool d under a certain amount of tension, the supply spool and tension means not being shown.
The means for causing the wrapping of the strands around each other in the present instance includes the traverse rail 0, having the notched guide 7 to receive the strands, and the cylindrical bar 'In, and some means (not shown) for causing relative movement as between rail 6 and bar m lengthwise thereof, that is, crosswise of the line of draft on the strands.
q is a guide for the strands, projecting from rail 6 below bar m, which not only in a measure contributes to the tension and keeps the strands close together (preferably by being set obliquelyFig. 2), thereby to insure the wrapping action, but in actual frictional contact with an appreciable portion, measured circumferentially, of the surface of the bar, as from A to B in Fig. 1.
The surface portion A-B of the bar is divided by a groove C midway thereof into two parts, which are thus spaced from each other.
The strands D D, coming from the supply spool and tension means, extend through guide 9, over bar m and rail 6 (in the notch of guide 7 thereof) to spool d. One or the other of the parts m and 6 being moved relatively to the other crosswise of the line of draft on the strands, (for instance, part 6 may be reciprocated so as to perform the function usual thereto in doubling machines of laying the strands on spool cl in coils proceeding from one end to the other thereof and part m may be reciprocated in synchrony with part6 but through a greater range and hence at greater speed), and the strands at the same time being drawn lengthwise by spool cl, the result will be that the portions of the strands in contact with the bar 'm will be rolled or wrapped around each other as shown in Fig. 2.
The space formed by groove 0 in the bar on. has this very important advantage, to wit, that the wiping action as between the strands and bar is confined to the right and left twists E E, which are the result of the wrapping or rolling of the strands around each other, and the crown F of the wrap is left free, so that the strands at this point F may move unimpeded around and around each other, as the wrapping proceeds, to an extent far beyond that possible where the bar is plain or ungrooved and therefore otters a positive obstacle to the strands at F rolling around each other at least when the tension has been augmented beyond a certain point by the twisting of the strands at E E. The obvious result is that it is possible by this invention to obtain a more tightly wrapped product and more perfect uniformity in the degree to which the suc cessive wrappings therein are carried than heretofore.
Having thus fully described my inven tion, what I claim is:
1. In combination, with means to draw the strands lengthwise a wrapproducing member having a pair of spaced surface-portions.
bearing each against the strands and extending smooth 111 a direction transverse of Gopies of this patent may be obtained for five cents each, by addressing the Commissioner the line of draft on the strands, and means to effect relative movement as between said member and strands crosswise of the draft line,'the space between saidsurface-portions being substantially coincident with the crown of the wrapping formed in the strands.
2. In combination, with means to draw the strands lengthwise, a wrap-producing EMORY J. Lrrrs.
