TRAP DEVICE FOR USE IN MACHINES OR FRAMES EMPLOYED IN TH E PREPARATION OR TREATMENT OF YARNOR THREAD.
Application filed February 12, 1925. Seria1No. 8,0:77.
To all whom it may concern:
Be it known that 1, WILLIAM BoTroMLnY, a subject of the King of Great Britain, residing at Greenfield, in the county of York, England, have invented certain new and useful improvements in trap devices for use in machines or frames employed inthe preparation or treatment of yarn or thread, of which the following is a specification.
The invention is for a trap device for use in machines or frames employed in the preparation or treatment of yarn or thread, and wherein said yarn or thread is, when moving, under constant tension, or approximately so, such as in doubling frames, windin g frames, gassing frames and the like. In some forms of. trapping devices referred to a pivoted and weighted member thereof is attached to a connection or wire acting as a support for the yarn on its way to the twist bobbin, the tension of said yarn operating to keep said member from making contact with a second member of the trapping device, movable about an axis, during normal running of the frame.
The object of the present invention, is to combine with a trapping device of the kind referred to, (and for which roughened or toothed faces are provided), a wire or connection for supporting the yarn, and inloop form as hereinafter described, for the purpose to be stated.
Vith reference to the accompanymg drawings, illustrating forms and applications of my invention, Fig. 1 is a side sectional elevation of a trap device and adjacent rollers of aring doubling frame, with my invention adapted thereto, and in the condition during normal movement of the yarn to the delivery rollers indicated. Fig. 2 is a similar view to Fig. 1 but under the changed conditions of the yarn having broken, and thus allowing the trapping operation to occur.
Fig. 3 is a View of the wire connection in Fig. 1 according to my invention and at right angles thereto. Fig. 4 shows the parts of Fig. 1 in position relatively to a ring doubling frame, or portion thereof, and according to the English system. Such arrangement is suitable either for wet or dry doubling, and in the former case, the water trough is assumed to be situated to the right of the figure, and as Well understood. Fig. 5 is an edge View of a portion of Fig.
1, but with a part added in relation to Fig. 4.
F ig. 6 shows a plan view of the major portion of said Figf l.
a is the usual long feed roller of the doubling frame, and Z) the usual short top rollers resting thereon, and between which top and bottom rollers the yarn, such as 0, passes as indicated@ That is to say, the broken line o represents the vario'us. ends which are to be twisted together, and which are assumed to come from the usual flanged bobbins mounted on a creel to the right of Fig. l for example, and after passing round a rod below, situated in a water trough when wet doubling is, employed, or not when dry doubling is employed, travel up. wards again as indicated, to'the device illustrated. 1'
d is one of the stands on which is mounted a series of rollers 22 aforesaid, and e is a glass rod, or guide, over or-through which the yarn to be twisted passes to the spindle bobbin. I i i The trapping device shown consists of "a member h which is here provided with teeth or a roughened surface, as at 2' below, and
is pivoted at 70 to a plate Z. This plate in Figs. 4; and 5 is seen to be adjustably connected' to another plate m extending from one end part of the stand d to the other,
a said plate m having wings n resting between the'sides of a channel plate attached to (Z. The plate at with the trapping members thereon can thus be readily dropped into position or removed. There are assumed to be as many of the trap-ping members in pairs to one plate m as there are top rollers to one part or stand (L.
A second member of a pair of trapping members is shown here as a toothed wheel 0, capable of rotation upon a spindle connected to plate Z aforesaid.
Connected to h is a stiff Wire r, so shaped according to my invention at its extreme end on the left of the figures as to form a convenient rest and guide for the yarn assing over the same, and having a suit able length of loop forming a gap 8 3). In further explanation of the drawings, it is to be stated that member h is weighted or designed so as to tend to drop to the position of Fig. 2 unless held up by extraneous means. Such means are provided by the wire 1' and the tension of the yarn a passing over the extreme end referred to, while-ever said yarn is intact or under tension. But should said yarn break, then the member it falls to the position of Fig.
b of h, and passed about the'rollers a, Z), and
to the spindle bobbin end, and pieced, the conditions of Fig. 1 are repeated.
It is obvious that when the yarn breaks, nothing must interfere with the action of the trapping device, but as the rest at the extremity of the wire 9 is necessarily connected to the trapping means, it will be seen that on those occasions when the yarn breaks near to the spindles of the frame, the free end of yarn may fly across. to an adjacent thread being twisted, or to other parts. If thisshould happen on the side of the wire at which the loop connection to its COIltlHllLtlOD 18 provided, the yarn so broken but held at or near its broken end would interfere with the necessary rise of the wire as a whole or with the complete trapping action, unless the loop or gap in said wire were deep enough to allow of said rise with the fouled yarn stretched across it. It will be seen that the extreme end of the wire 7* allows the yarn to rest merely upon the same, during normal running of the frame, or said end is what may be termed an open support as distinct from an ordinary eyelet form of support.
A projection or stop 16 from the plate Z limits the upward or opening movement of member h. A wire swivel piece u is shown in Fig. 5 pivoted to plate Z which when turned to lie across the underside of member it keeps said member in the raised position, of Fig. 1. This is useful, for example, when the spindles are being doffed.
A porcelain or suitable guide is assumed to be provided at 1;, one for each trap device and which guides are connected to a bar to extending across the various stands, or across each stand, whereby the longitudinal movement of said bar in the slotted parts of the plate Z (see slot in Fig. 4, the bar being omitted therefrom), enables the yarn to be moved sideways out of the spaces between the members 7L, 0, for example at those times when doubling operations are suspended.
ln Fig. 6, the yarns c are not shown continued around the rollers b and beyond, to
prevent confusion.
I claim In machines or frames employed in the preparation or treatment of yarns or threads employing a rotatably mounted member forming one of a pair for trapping the yarn between on the breaking of the latter, and a wire connection from the firstnamed member for supporting the yarn and transmitting the pressure due to tension thereof to said member, the contact faces of both members of the trapping device being toothed or roughened, the wire connection aforesaid constructed in loop form near its free extremity, and adapted at said free end to form a rest or open support for said yarn, substantially as herein set forth. I
In testimony whereof I have affixed my signature.
WILLIAM BOTTOMLEY
