This invention relates to yarnl spools and is especially adaptedto the construction of yarn spools intendedfor use in tube frames, such as areused for weaving Axminster carpets andthe like, and is intended to provide a strong and durable construction applicable to an all metal spool that permits the replacement of damaged parts of the spool while utilizing the undamaged'parts, thereby effecting large economies in the use of such spools whose various parts are peculiarly subject to injury and damage. The construction also permits the assembling from substantially universal parts of spools that are adapted to form either the end spools or the intermediate spools of a multiple spool tube frame or the spool of a single spool tube frame. It also provides a constructiony by which plain cylindrical `barrels or barrels provided with llongitudinal grooves for the reception 'of yarn clamping means may be interchangeably used with thev same 'heads and with'the same bearing journals of various types appropriate to particular locations. The present invention is anV improvement of this type of assembled yarn spools and an important feature resides in the construction by which the end heads are interlocked with the spool barrels by means of rigidly applied interlocking members that prevent rotative displacement between the spool head andthe according to its intended location in the tube frame, but whatever the intended position of barrel. This rigid interlocking means may be integral with the spool barrel or may be rigidly but detachably secured 'to' the end head of the spool.
In the accomp anymgdrawing is illustrated two diiferent vforms of construction embodying the principles of this invention, in which Fig. 1 is a longitudinalv central section showing 'a pair of end to end spools in assembled relation for use'in a tube frame.
Figs. 2, 3 and 4L are detail views showing respectively the construction of the anchoring member and its relation to the barrel in which it is inserted andthe end head to which it is secured.
Figs. 5, 6, 7Y and 8 are detail views showing i the spool coupling members and the manner ofsecuring them to their respective spools of two aligned yarn spools. Y f
Fig. 9 is a longitudinal central "section showinga'plain cylindrical barrel without the longitudinal groove in assembled relation to the same heads and journal members as are illustrated in Fig. l. f
Figs. k10, 11,12 and 13 are detail views showing the means by which the end heads, similar to those shown in Fig. 1, are secured to a barrel of plain cylindrical form without the longitudinal groove.
' kln the practice of this invention, as illustrated in Fig. 1, the barrel 1 comprises a suitable length of cylindrical tubing provided on one side with a longitudinal groove or depression 2 for the reception of a clamping member or' wire, such as is often usedfor `clamping the inner ends of the yarn elements to the spool barrel. v
At a short distancefrom the end of each barrel is sccuredan anchoring member 8, which comprises ardisc 3 provided with an offset peripheral ange 3a and also a smaller offset inner flange 3b surrounding a central orifice and lhaving its inner surface threaded to receive an anchoring or fastening screw, which forms a part of the journal bearing construction on which the spool is rotatably supported when in use.
The Ajournal construction itself is varied the journal, whether it vis tobe mounted in the outside or end brackets of the tube frame or in the intermediate stands or brackets,
all journal constructions are interchangeable The end bracket journal construction comf prises aV threaded fastening bolt or screw 6 whose reduced shank has threaded engagement with the threaded boss or hub 3b of the anchoring member, while its larger outer end portion is preferably of polygonal form and. `is provided with an outwardly extending bearing pintle which, as shown at the left of Fig. 1, embraces a telescopic shouldered pintle 7 mounted in a central bore of the peripheral notch 3C for the reception of the internal projecting rib 2 that forms the longitudinal groove and, after being inserted a proper distance inside the end of the spool barrel, is integrally secured thereto preferably by spot welding, the terminals of the welding apparatus being conveniently applied against the inside of the iiange 3a and the opposing exterior point of the barrel.
The anchoring members 3 serve not only as anchorages for the attachment of the journal members and for clamping the end heads 4 iirmly and rigidly against the ends of the barrel, but also by reason of their notched peripheries serve as means for interlocking the end heads against rotative displacement relative to the barrel, beside affording stiffening spiders for internally supporting the hollow barrels. Each end head l is provided with an interior inwardly offset annular portion 4 forming an annular shoulder adapted to fit snugly inside the end edge of the barrel. At one point the end head is provided with a radial slot or recess 1lb intersecting the annular shoulder and dimensioned to allow the end portion of the inward rib 2 to be seated therein to form interlocking engagement. The end head d is placed against the 1end of the barrel with this slot or aperture 4J longitudinally aligned with the notch 3C in the anchoring member, and is clamped tight-ly in place by screwing in the fastening bolt 6. Therefore, the inwardly projecting rib 2 forms a rigid interlocking key interlockingly engaging the notch 3C of the anchoring-member and the slot ab in the head. This construction avoids the use of a loose interlocking member which has been heretofore proposed to use and which permits a certain amount of looseness in the connection between these two members.
in the case of a multiple spool tube frame it is usually desired to couple together the adjacent ends of the spools to secure uniform rotation. ln this case, the end head construction is similar to that already described for the outer ends of the spools, but there are provided for the respective spools a coupling journal member 9 radially slotted to formsegmental teeth 9a, which interlock with similar projecting teeth 10L formed on the complementary journal member 10. `Both journal Lend-'ss members are provided with peripheral notches to receive the extreme ends of the longitudinal ribs 2, so as to be interlocked with the head and with the barrel to prevent rotative displacement. 'i3
In Fig. 9 we have illustrated how the same heads and journal members may be applied to a plain cylindrical barrel which has no longitudinal depressed rib for receiving a yarn clamping member. In this case, the 'f barrel l0 is a plain cylindrical tube provided with the interior anchoring members 3, such as have already been described. The rigidly supported interlocking means, by which the end head is positively locked against rotative displacement on the barrel, in this case for the outer end of the spool, comprises a centrally perforated Hat disc 2l provided with an axially projecting tongue 21a adapted tol pass snugly through the slot 4b in the head S5 and the slot 3c in the periphery of the anchoring member. Thisinterlocking member 2l is placed fiat against the central portion of the head 4 with its tongue projecting through the aligned slots aforesaid and is rigidly clamped against the head for which it forms a substantial reinforcement by means of the journal attaching member 6.
In order to lock the coupling journal mem-T bers 9 and l0 to their respective spools and '95 hold them against rotation we employ two discs 22 of substantially thinner metal than the discv 2 1, each having a short axially projecting tongue 22jL diametrically opposite toMv a peripheral notch 22h. These two interlock- 100 ing disc members are placed face to face with the prong or tongue of each projecting in opposite directions through the notch 22h of the other, so that one tongue passes throughsa the slot 4b and into engagement with the pe- 105 ripheral notch 3 in the anchoring member 3, while the outwardly projecting tongue enters the peripheral notch 9b, or 10b as the case may be, of the journal member. As these. head locking members are clamped iirml against the central portions of the end heads 4 by the attaching screws 5, it will be seen that they also are rigidly supported in the construction and therefore prevent loose,. ness or plal in a rotative direction. The advantage o making them in two pieces is that in order to give the necessary sharpness of bend for the interlocking tongues they must be made of thin metal and must be, dimensionedv with suhicient precision so that when placed in position they will slightly overlap on the one side the edge of the slotted flange of the anchoring member and on the other side-the notchedportion of thejournal` coupling member.
It will be observed that the only additional parts used with the plain cylindrical barrel, thatv are not, used in the longitudinally grooved, barrel, are these locking discs 21 and 22, but these members being made of pressed Laar/fines metal, formed in a single operation of a press,
are of such triing cost that they do not appreciably add to the expense of the spool.
Therefore, we have a simple rigid and strong construction by which spools with or without longitudinally grooved barrels may be assembled to suit any desired location in a multiple spool tube frame or in a single spool tube frame, which are adapted not only to be reversed or to be transposed for the purposes of reversing the pattern, but which effects great economy, since any damaged part may be readily and conveniently replaced without going into the workshop, while all the undamaged parts are conserved for continued use. At the same time, in whatever form assembled the construction can be given the same degree of rigidity and absence of looseness that is obtainable in a permanently built up spool.
TvVhat we claim is:
l. A yarn spool embracing in its construction a tubular barrel formed with an inwardly projecting longitudinal rib, an interior anchoring member integrally secured inside the end portion of said tube and having a peripheral notch for receiving said rib, an end head provided with an inwardly offset annular portion dimensioned to be inserted in the end of the barrel and having a slot arranged to receive the end of said rib, whereby the head is rigidly and positively locked `against rotative displacement on the barrel, and coaxially disposed releasable fastening means having threaded connection with the anchoring member and exerting an external thrust vagainst the end head, thereby permitting replacement of the head and of the fastening member to adapt the spool to different positions in the tube frame.
