- Figure 11 is a partially exploded isometric view of the spool shown in Figures 6 to 10, inclusive, with parts broken awayand other parts in section and showing the spool tilted for purposes of clarity.
- the numeral I0 broadly designates the tubular member or body of the improved bobbin or spool.
- This tubular body l0 includes an outer or first tube ll, preferably of a plastic or a pressed fiber or other close-grained material, which fits snugly over a second or inner tube I2, this second tube preferably being of metal such as aluminum to give additional strength to the bobbin or spool and so as to be as light in weight as possible.
- the outer tube II maybe adhesively secured to the outer surface of the second tube l2 or it may be moulded integral therewith as desired.
- the second tube l2 is'provided with arplurality of circularly spaced longitudinally extending reinforcing ribs or projections l3 which are preferably cast integral'with the second tube l2.
- the second tube [2, being of metal and being reinforced by the ribs l3, serves as a strengthening member for the tubular body 10, andfthe outer tube ll, being made of a plastic material, may be provided with a smoother outer surface than would be possible with a metal suchas aluminum and, also, upon the exterior surface of the outer tubular member H being scarred or otherwise damaged, the outer tubular member ll, may be removed from the second tubular member l2 and replaced with a similar tubular member having a smooth outer surface thus considerably lengthening the life of thebobbin or spool.
- the outer tube II also serves as an electrical insulator against static electricity and inasmuch as the yarns wound onto many types of bobbins or spools substantially of the type shownin the drawings, are usually synthetic and are subjected to relatively extensive variations in temperature causing them to expand and contact, the outer tube II will assist in minimizing the variations in diameter and length of the tubular .body 10 of the spool due to these variations in operating temperatures, and the inner tube I2 will prevent collapse of the tubular body I 0 under contraction of the yarns wound thereon.
- a firstand a second or an upper and a lower headmember broadly designated at and 2
- a detailed description of the first head member 20 will now be given.

- the lower or inner surface of the disk 21 is provided with an annular groove 30 for reception of the upper edges of the outer tube H and the second tube I2 and it will be noted that the upper surface of the first head block 23 is spaced below the upper edges of the tubular members II and [2 so the medial portion of the disk 21 may be inserted within the second tube l2.
- the first head block 23 has an upwardly projecting restricted or pilot portion 32 integral therewith which is preferably tapered slightly and the disk or flange 21 is provided with bore 33 which is adapted to fit snugly over the upwardly projecting restricted portion 32 of the head block 23.
- the head block 23 also has a restricted outer portion 34 integral therewith which is of substantially less diameter than the. restricted portion 32 thus forming a shoulder 35 which is adapted to be engaged by a handle or knob 36 secured on the restricted portion 34 of the head block 23 as by an adhesive or by the use of a synthetic resin which, upon being subjected to relatively high temperatures, will become pliable and will permit removal of theknob 36 from the restricted portion 34 of the head block 23 so the disk 21 may be removed from the restricted portion 32 for replacement purposes.

invention relates to improvements in.
spools and more especially,in".. spools of a type employed in the textile industry for use on uptwisters, spinning frames, twisters, and the'li'ke and also for use as a warping spool.
It is well knownto those familiar with the art that in many instances yarnis withdrawn from a spool to a point disposed insubstantialaxial alinement with the spool and'this requires that. the yarn be withdrawn past a flange or head-hav-- ing a rounded peripheral edgeand, upon thisedge becoming scarred or damaged in any Way, such as by handling the spools; the yarn, upon being withdrawn therefrom, will usually-be severed or broken from engaging the rough or scarred places on the periphery of the head orthe spool. Here tofore, this has required that the spools be "dis carded or that a new head beprovided ior'the spools. l
It. is therefore an objectbfthis invention to provide an improved spool structure having a tubular portion and removable headtportions and being provided with rmaans for easily securing the head portions to the tubular'portion;
It is another object of this inventionto provide an improved spool structure comprising a. tubular body member having apluralityof longitudinally extending-projections on the inner surface there of'and to further providea disk adapted'to fit in the tubular member andhaving notches'th'ere to coincide withlthe projection on the tubular member and the projections or'rthe tubular mem-' ber being notched or cut away intermediate the ends thereof and at points, adjacent one another so that, upon the disk being inserted in the tubu larmembenthe diskm'ay be partially rotatedfin the notches in the longitudinally extendlng'pro' jections and whereupon a removableflan e may be fastened, as by screws, to-thediskto' thus lock the flange in-pla'ce against the end of the member forwithdrawing' the disk withthe flange.
fromlthe. tubular .mernbei'flwheniit'is desired to replace the same.
It is another obJect' thisinvntio i o l r 1 17'C1ai'ms (Cl. 242-124) vide a bobbin comprisinga tubular bodyhaving a plurality of spaced longitudinally extending ribs or projections on the inner surface thereof, which.
are provided with coinciding notches to ,form .a, circular groove on the inner surface oiytl e t-ubue; lar body adjacent each endthereof, and--, to, :fur-u ther, provide a disk having notches therein adapts ed'to coincidewith the ribs in the tubulanbody and to fit within the tubular member whereby the disk may be insertedin the tubular mernberl'and partially rotated in the oiroula'itg' i'oove to where its notcheswill not coincide with the ribs to prevent'the disk from beingre'inove'd fromv the tubu lar member.

Referring more specifically to the drawings, the numeral I0 broadly designates the tubular member or body of the improved bobbin or spool. This tubular body l0 includes an outer or first tube ll, preferably of a plastic or a pressed fiber or other close-grained material, which fits snugly over a second or inner tube I2, this second tube preferably being of metal such as aluminum to give additional strength to the bobbin or spool and so as to be as light in weight as possible. The outer tube II maybe adhesively secured to the outer surface of the second tube l2 or it may be moulded integral therewith as desired.
The second tube l2 is'provided with arplurality of circularly spaced longitudinally extending reinforcing ribs or projections l3 which are preferably cast integral'with the second tube l2. The second tube [2, being of metal and being reinforced by the ribs l3, serves as a strengthening member for the tubular body 10, andfthe outer tube ll, being made of a plastic material, may be provided with a smoother outer surface than would be possible with a metal suchas aluminum and, also, upon the exterior surface of the outer tubular member H being scarred or otherwise damaged, the outer tubular member ll, may be removed from the second tubular member l2 and replaced with a similar tubular member having a smooth outer surface thus considerably lengthening the life of thebobbin or spool.
The outer tube II also serves as an electrical insulator against static electricity and inasmuch as the yarns wound onto many types of bobbins or spools substantially of the type shownin the drawings, are usually synthetic and are subjected to relatively extensive variations in temperature causing them to expand and contact, the outer tube II will assist in minimizing the variations in diameter and length of the tubular .body 10 of the spool due to these variations in operating temperatures, and the inner tube I2 will prevent collapse of the tubular body I 0 under contraction of the yarns wound thereon.
Adapted to be secured against opposed ends of the tubular body [0, in a manner to be presently described, are a firstand a second or an upper and a lower headmember broadly designated at and 2|, respectively. In many instances these head members 20 and 2| maybe identical and are shown in Figures'l,=2, 3, and 4 as being substantially identical. A detailed description of the first head member 20 will now be given.
The first head member 20 comprises a first head block 23 which is substantially circular in cross-section and is provided with a plurality of circularly spaced, longitudinally extending grooves 24 cut in its periphery, each of the grooves 24 being adapted to coincide with and to slidably fit in engagement with the respective projections I3 in the interior of the tubular body 10, and the first head block 23 being adapted to slidably or loosely fit within the upper portion of the second tube I2 as shown in Figure 2.
In order to assist in sealing the upper end of the tubular body I0 as shown in Figure 2, the lower or inner surface of the disk 21 is provided with an annular groove 30 for reception of the upper edges of the outer tube H and the second tube I2 and it will be noted that the upper surface of the first head block 23 is spaced below the upper edges of the tubular members II and [2 so the medial portion of the disk 21 may be inserted within the second tube l2. The first head block 23 has an upwardly projecting restricted or pilot portion 32 integral therewith which is preferably tapered slightly and the disk or flange 21 is provided with bore 33 which is adapted to fit snugly over the upwardly projecting restricted portion 32 of the head block 23.
The head block 23 also has a restricted outer portion 34 integral therewith which is of substantially less diameter than the. restricted portion 32 thus forming a shoulder 35 which is adapted to be engaged by a handle or knob 36 secured on the restricted portion 34 of the head block 23 as by an adhesive or by the use of a synthetic resin which, upon being subjected to relatively high temperatures, will become pliable and will permit removal of theknob 36 from the restricted portion 34 of the head block 23 so the disk 21 may be removed from the restricted portion 32 for replacement purposes. The knob 36 is provided to be grasped by an operator for carrying the bobbin or in a dofiing operation as on a spinning frame or twister. v
In order to secure the first head block 23 and the flange or disk 21 in position at the upper end of the tubular body In, the inner surface of the second tubular member l2 has an annular groove therein spaced from the upper surface thereoi and which is of the same depth as the ribs l3 or, in other words, each of the ribs I3 is provided with a notch or groove 40 (Figure 5) which is of sufficientwidth to permit a locking member or disk 4| to be slidably rotated therein. This locking disk 4| has a-plurality of circularly spaced notches or slots 42 in the periphery thereof which are spaced so as to coincide with the ribs l3 of the second tube I2. The locking disk 4| also has a plurality of circularly spaced threaded bores 43 therein, these bores 43 being spaced according to the spacing of the longitudinally extending grooves 25 in the first head block 23 and being provided for the reception of the screws 26. The locking disk 4| also has a centrally disposed opening 44 therein for purposes to be presently described.
' It is 'thus seen-that -the= disk4 I, which. is :of slightly less diameter than' the interior diameter of thesecond tube! 2; may-beinserted in the tube It with the notches in theperiphery-thereof straddling the-longitudinallyextending ribs-J3. I

or disk-like portions 95 and 86, respectively. The outer and inner circular portions 85 and '86 of the head block 89 are provided with a plurality of circularly spaced coinciding grooves or notches 91, the notches 81 being so spaced as to coincide with the ribs I3 and the projections 15, which are actually a part of the ribs 13 when the head block 96 is positioned within the tubular body I0.
The outer circular portion 85 is provided with a plurality of circularly spaced bores 90 and the inner circular portion 86 is provided with a plurality of circularly spaced threaded bores 9|, which coincide with the bores 90 in the circular portion 85. The bores 90 are adapted to slidably receive screws 92 which are threadably embedded in the threaded bores 9|. The screws 92, like the screws 26 in the original form of the invention (Figure 3), are preferably of a type which are flush with the outer surface of a flange 93 of the head members 8| and 82 for securing the flange to the outer surface of the head block 80.
The head block 80 is provided with a longitudinally, extending and centrally disposed bore 95 into which the upper end of a relatively thin walled tube 96 is adapted to snugly fit. This third or inner tube 96 is of a substantially less diameter than the inner diameter of the second tube 12 so as to provide a dead air space between the second and third tubes 12 and 96 for insulating purposes. 7 Y
The third tube 96 has a pair of bushings I and NH inserted in opposed ends thereof and suitably secured therein as by a pressed fit. The bushings I99 and HH are spaced slightly from the outer ends of the tube 96 and are provided with coinciding tapered bores I02 and I93, respectively. These bores I02 and H13 may be straight or tapered and may be of the same size or of difierent sizes according to the particular spindle onto which the spool or bobbin is adapted to be placed.
It will be observed in Figure 8, that the medial portion of the flange 93 is provided witha circular recess I05 which is adapted to slidably receive the upper end of the tubular body 19 and against the bottom of which the tubular body 19 and the upper surface of the circular portion 85 of the head block 80 are adapted to be secured.
by any suitable means such as the screws 92.
In mounting the flange 93 on the upper. end of the tubular body as shown in Figure 8, the
The flange 93 is also provided with a bore ms in'which an invertedcup-shaped cap member I 01 is secured, as by a pressed flt. This inverted cup-shaped member I0! is of greater height than the vertical thickness of the flange 93 and projects into the upper end of the tube 96, the bushing I00 being spaced from the upper end of the tube 96 for this purpose. The inverted cupshaped member I01 has an opening H0 therethrough through which the upper end of a spindle or the like, not shown, may extend.
The lower head member 82 difiers from the upper head member 8| in that the flange 93 is provided with slot III in addition to the opening I06, this slot Ill being provided in lieu of the inverted cup-shaped member ID! in Figure 8. The slot I l l is for the well-known purpose of mounting the bobbin or spool on a spindle having a suitable key for engagement with the slot Hi to thus cause the bobbin to rotate with the spindle.
The bottom or second head member 62 also has a circular recess in the flange 93 of such diameter as to receive the lower end of the tubular body 10, the lower end of the second head block 86', and the lower end of the third tube 96 in Figure 8. The bushing [0| is preferably spaced from the lower end of the tube 96 if it is desired to have a projection from the medial portion of the flange 93'.
If so desired, one end of the other of the tube 95 may be threadably embedded in the corresponding head block or 80' and may be then secured prior to the head block and the third tube being mounted in the tubular body ID as shown in Figure 8.
When it is desired to remove the flange 93, the screws 92 may be loosened and the head BI and head block 80 may be partially rotated to wherethe tubular member 10- with the screws 92.still partially embedded in the threaded bores 9 I.
The purpose of the innermost tubular members.
or tubes 55 and 96 of the respective forms of the invention being spaced apart from the tubular bodies llland 10, respectively, is to provide a dead air space between the innermost tubes 55 and 96 and the respective tubular bodies I0 and 10 to thus serve as an insulator since most bobbins are subjected to excessive variations in temperature and humidity and this dead air space will serve in minimizing the amount of variation in length and diameter of the tubular bodies It and 19 which are usually caused as a result of these variations in temperature and humidity.
It is thus, seen that I have provided an improved bobbin which is relatively light in structure and having head members thereon which may be quickly removed and easily repaired or replaced. Also, I have provided a tubular member having internal ribs therein and I have further provided a disk adapted to operate in slots or grooves in said ribs for holding the disk in place whereby a head block may be placed against the disk and a flange may, in turn, be placed against the outer surface of the head block and the tubular member and secured by screws to the disk, there being suitable bores or grooves provided for the passage of the screws through the head block, to thus secure the flange against vtheouter surface of either end of the tubular member.
It is evident that the reinforcing or second tubes l2 and 12 of the respective tubular bodies It! and 19 may be of a plastic material if so desired, however, it is preferable that this tube be made of a magnesium or aluminum alloy. Also, the longitudinally extending ribs l2 and 19 in the respective tubular bodies--10 and :10 serve to .re- -inforce the respective tubular bodies d and :to such :an extent that they willwithstand a substantially: greater amount: of pressure and strain resulting from the-many types of syntheticlyarns now in use than ordinary tubes which havo not beenprovidedwitlrthe reinforcing [ribs and which have heretoforelbeen in ,useiin' themanufactureiof textile spools. "The :ribs and the relatively light -:weight of the material used informing the sec- -ond tubes associated with eachwo'f-the tubular bodies l0 and' l'fl do not add- -substantially to the weightofthe spool.
