This invention relates to yarn spools, and is especially adapted to yarn spools such as are used in axminster tube frames in which plural spools are placed end to end for the weaving of wide seamless rugs or carpets.
The invention is particularly concerned for the most part with the improvement of tubular barrel yarn spools which are becoming increasingly popular in the trade and is intended to provide a construction and arrangement y which the substitution or replacement of new heads may be conveniently and securely made, while also making provision for the interchange of various types of gudgeon journals for rotatably supporting and also for interlocking the spools.
One important feature of the present invention resides in the combination with a removable end head with a fastening gudgeon interlocked with an interiorly disposed anchoring member to hold the removable end head firmly in position combined with means to prevent the accidental loosening of the fastening gudgeon that is sometimes occasioned by the continued revolution of the spool upon its supporting gudgeon. Another feature of the invention consists in the provision by which the head fastening gudgeon is provided with a disappearing axial pintle for rotatably and releasably supporting it in the end bearing bracket of the tube frame. These and other features of the invention will be described in detail in the following specification and will be defined in the claims hereto annexed.
In the drawings Fig. 1 is a side elevation in central section showing two end to end spools in interlocked relation.
Fig. 2 is a detail showing an endwise elevation of the head fastening gudgeon and its locking washer.
Fig. 3 is an end elevation of the inner end of the yarn spool showing its interlocking gudgeon.
Fig. 4 is a central cross sectional view of this gudgeon.
Fig. 5 is an end elevation of the opposite or adjacent spool.
Fig. 6 is a detail view in central cross section showing the other interlocking gudgeon.
Fig. 7 is a plan view of the interlocking key used to prevent accidental rotation of the end head relative to the spool barrel.
Fig. 8 is a cross sectional view of the anchoring member and the interlocking key.
Fig. 9 is an end elevation of the parts shown in Fig. 8. Y
According to the practice illustrated in the drawings, we provide a tubular spool barrel 1 in whose opposite ends are inserted a flanged transverse anchoring member 2 provided with an internal bored and threaded hub 2, and having at one side a radial slot 2 for the reception of a locking key hereinafter to be described.
The end heads 3 of the spool are of disklike construction and are provided with an annular ofl'set shoulder as at 3 adapted to fit in i to the open end of the tubular barrel, so as to be co-axially aligned therewith, said heads being fastened in position by means of fastening gudgeons 4.
These fastening gudgeons 4 have their outer ends somewhat larger than the inner shank portion to form a circumferential shoulder 4 which engage the edge of the central perforation formed in the head 3 and which act to clamp the head firmly against the end of the tubular barrel by means of the interlocking or screw threaded engagement between the inner end of the shank and the interior threaded hub portion of the anchoring member 2.
The outer enlarged end of the gudgeon is of polygonal form and, between the shoulder and the edge portion of the head surrounding the central aperture is interposed a washer 9 of general circular form having its periphery notched, as shown at 9*, and having opposite said notch a flexible tongue 9 for a purpose hereinafter described.
The gudgeon is counter-bored from its outer end and the inner end wall is perforated by a smaller bore to leave an annular seat for a compression spring 6, which engages the shoulder of an elongated pintle 5 to force the pintle normally outward while allowing it to be pressed entirely inside the bore when insertin the spool in the bearing arms of the tube rame rackets. To prevent the spring from ejecting the intle too far,.the inner protruding end of t e pintle, as shown at 5, is upset to form projections limiting the outward movement of the pintle. It will thus be seen that the gudgeon with its disappearing pintle forms a self-contained unit that can be readily removed from and restored to operative position when it is desiredto replace the end head of the spool.
In assembling the device the self-contained gudgeon unit is inserted first through the ocking washer 9 and then through the central aperture in the end head until its inner threaded end engages the internal thread of the anchoring member 2. A wrench applied to the polygonal head of the gudgeon permits it to be screwed tightly to clamping position to fasten the end head concentrically in place.
When this is done the outer end of the tongue 9 is doubled upon or folded u on itself in position so that its s uared on will engage the fiat peripheral ace of the polygonal head.
Before the parts are assembled, however, a key 7, in the shape of a sheet metal cross, is inserted through the aperture or slot 2 in the anchoring member and the slot 3 in the head is turned to register with the outer end of this key 7 when the end head is placed in position against the end of the barrel. The cross arms are of a width corresponding to the space between the fiat face of the anchoring member 2 and the opposed face of the offset hub portion of the head 3, so that the key cannot rock and consequently acts to prevent accidental rotation of the head, since the anchorin member 2 is permanently fastened either y spot welding or equivalent means inside of the tubularbarrel.
It will, therefore, be seenthat the heads are very easily replaceable and, when replaced are as securely fastened as when the spools are originally made. Furthermore, t e loosening of the clamping engagement of the gudgeon with the anchoring member is positive y prevented because not only does the key 7 look the end head against accidental rotation, but the locking washer 9 acts as a ositive preventative against the accidental rotation of the gudgeon itself, since its notch 9 interlocks with the outwardly projecting end of the key, which latter is in terlocked with the stationary or fixed anchoring member. The provision for locking the gudgeon against accidental rotation is important, because without such means the gudgeons frequently show a tendency to work loose, thus allowing the head to become loose and causing trouble.
In multiple spool tube frames it is often desired to make provision for interlocking two adjacent spools together to prevent unequal rotation thereof. Moreover, the middle bearing stands are often made with a largerbearmg aperture to su port the spools than are the end brackets. n this case two annular coupling members, a female member 11 and a male member 12, are secured to the adjacent ends of the aligned spools by means of fastening gudgeons 10 having threaded engagement with inserted anchoring members 2 similar to those already described. A key 7 inserted between the end hpml 3 d the anchoring member 2, so as to pass through two registering slots in the respective members and engage a notch 11 in the periphery of the gudgeon 11, serves to prevent accidental rotation of the bearing members and of the head.
When winding the yarn on the spools it is the practice to rotate the spool to draw off the yarn from the yarn package and, in order to make proper provision for this the keyreceiving slots 3 in the head are extended outward far enough to make provision for the reception of an eccentric pin in the revolving clutch member that rotates the spool in order to wind on the yarn. As the clutch member forms no part of the present invention it is illustrated only in dotted lines to the right of Fig. 1 in order to show how such a clutch pin may penetrate this slot or opening 3 in order to impart rotative movement to the spool.
