Application September 26, 1939, Serial No. 296,670
This invention relates to paper cones designed for use as cores for thread packages in the textile industry, and its general object is to provide a cone that is perfectly balanced and round throughout the entirecircumference thereof,and has a uniform outer surface free from the objectionable longitudinal ridge seam present on' cones now in general use. f
A further object -is to provide a cone constructed from several conical shells that has its apex end colored for identification purposes, either by using a colored hard drying material or by providing openings in the outer shell and disy moved from the sheet.
posing a lining of contrasting color between the inner and outer shells to show through the openings.
Another object is to providey a cone for the purpose set forth, that is simple in constructionl l' panying Adrawings and specifically pointed out in the appended claims.
I n describing the invention in detail, reference will 'f be' had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:
Figures 1, 2 and 3 are plan views of one of the forms of the disk segments used in producing my cone.
Figure 4 is a longitudinal sectional view taken through the shaping and pressing apparatus.
Figure 5 is a-view of the outer or female die of the apparatus.
Figure 6 is a view'of the inner orI male die.
Figure 7 is a sectional view taken through the base member of the apparatus. Figure 8 is a transverse sectional view taken through the apparatus in its entirety with a cone therein. l i
Figure 9 is a view of the segments of Figures 1 to 3, rolled in conical shell formation and illustrates the manner of mounting'the same, so that the seams are disposed out of registration.
Figure 10 is a view of a shell providedwith a modified or locking seam. I
Figure 11 is a fragmentary view ofa shell provided with an overlapping joint or seam.`
I Figure 17 is a view of a slightly modified form of segment.
Referring to the drawings in detail, and particularly to Figure 15, the reference numeral l indicates a. sheet of paper stock that may or may not` have a roughened or serrated surface and which is stamped or cut to provide segment blanks 2 from which my cone is made, the segments being first removed and may be retained in their original shape as shown in Figure 16, or may have a tip of the apex cut away in arcuate formation, as at 3 in the form of Figure 17 or a larger portion of the apex may be cut away in arcuate formation as at 4,`in the form of Figures 1 to 3 inclusive.
In any event, each segment is rolled upon itself in conical formation as shown in Figure 9 to provideV shells 5. Two or more of these shells with the longitudinal edges of each disposed in abutting Contact, are nested one within the other, as likewise shown in Figure 9, and the outer faces of the inner shells are coated with any suitable adhesive material, such as liquid or plastic cement for securing the shells in face to face relation to produce a cone of several layers of material, to render the same sufficiently rigid to prevent any possibility of damage thereto..
When the shells are nested, the seams which are indicated by the reference numeral 6 'are disposed out of registration with each other, as clearly sh'own in Figure 9, and the shells are pressed in nested formation, as well as shaped to provide a complete co're for the thread package, b y the apparatus shown in Figures 4 to 8 inclusive.
While all the shells are originally of the same size, as they are cut from the sheet as shown in Figure 15, it will be obvious that the inner shells must be slightly reduced in size in order for the shells to snugly t one within the other, particularly if the longitudinal edges of the inner shells are disposed inabutting contact, as shown, and which is of course desirable, so that the inner face of the cone will be uniform and`free from a seamridge like thel outer face, as the longitudinal edges of the outer shell must be disposed in abutting contact, because such is one of the most important features of my cone to meet the exing-inserted in the femalev die.'
` eluded inthe apparatus and xed in the groove is the large end of a truncated conical hollow inner or male die II that is perforated throughout the entire area thereof to allow for the passage of air therethrough to breaka vacuuxnthat may exist during the use of the apparatus.
Cooperating with the inner or male die forre.-
ceiving,l shaping, pressing and securing the nested shells together, .is an imperforate outer or female die I2 that is likewise of ltruncated conical hollow formation, but the outer'die` is made toy provide apair of like sections, each constituting 'a half in the form shown, and being hinged together along one of the longitudinal edges thereof by barrel type hinges I 3, while the opposite longitudinal edges are detachably secured toe.
gether by suitable--latching means. The latching means shown includes arms I4 having one of their 'e'nds pivoted to one section and extending from the other section 'are studs I5 arranged in the path of openings inthe free ends of the arms to be received therein for latching the sections together, as clearly shown `in Figure 8.
In the use of vmy apparatus, .I want it understood that the blanks-2 are individually or lcollectively applied within the outer or female die I2 and it wiii be obvious that the blanks wh'esbeing -inserted therein will conform to the conical formation thereof. The sheet I of paper stock from which the blanks are cut, may have a coating of adhesive material thereon, that is retained on the blanks when they are cut rorn the sheet Land inthat event the adhesi ely coated face of the blanks are moistened prior to or while be- However, the blanks may not have a coating of adhesive material thereon, and then liquidcen'ient or plastic must be applied thereto, as will be apparent. It'
will of course be understood that the blanks are inserted with their small ends innermost, and by following the shape of the female die, they are converted into the shells of my cone. The apex -4 as including concentrieally to theopposite end of the cone.
that the cone will beperfectly balanced, a feature wlieci'h is of importance in a cone of `this charac l The shell I8 of the form of Figure 10 is shown a lock Joint, in that one longitudfnal edge thereof has formed thereon tongues I1 to bereceived in recessesin theopposite longitudinal edge, but in any event theedges are disposed in abutting relation and the same is true withrespect to the tongues and recesses. It will be noted that the tongues I1 increase in width from their connection with their longitudinal edge for fitting association with the recesses, so as to prevent any possibility of the tongues being pulled from the recesses, thusV the edges' are firmly locked together, and I want it understood that the tongues. and recessescan be of other shapes from that shown. It will be further understood that the shells of Figure 10 are disposedin nested relation and secured accordingly in the '.same manner as the shells /toprov'ide a cone.
- In Figures 11 and l2', I. have illustrated a shell which for distinction isiindicatedyby the rei'-l erence numeral I8, as having an' overlapping `ioint I9, or in other words the longitudinal edgesof the shell I8 are cut in rightV angle formation to .providefianges for disposal in overlapping relaition with respect to each other, as clearly shown the shells may be skivedWitl 'i-the\skived edges disposed in overlapped relation. However, it will be understood that regardless of the type of Joint used theshells of these forms are adhesively secured together in exactly the saine manner as the other shells, for disposal in nested formation to provides completed cone, asbest shown in Figure. s
It has beempreviousiy set forth, that it is necessary for the outer surface of the apex e ds of cones of this character, to .be smooth, in orriier to' prevent damage to the thread, and while the smooth, I likewise may use ends er the shells are disposed within the recess 9, and pressure is appliedto'the head plate I0 for forcing the shells together and the apex ends thereof within the recess 9 to follow the shape of the latter, as will be obvious upon inspection of Figure 4. The dies may `be heated, to expedite the drying action of the adhesive material be` tween the shells, as well as the shaping action of the rounded apex end thereof. Again, in the event the shells are made. from paper having smooth faces, the inner surface of the die I2 and the outer surface of the die' II may be serrated from adjacent the apex ends thereof to its opf i posite end to produce inner and outer roughened surfaces on the cone. However, the apex end portion of the ,die I2 is smooth so that it will produce a smooth apex portion on the cone, especially in the event the cone is made from paper having a roughened face. upright 8 not only cooperates with the curvature of the recess 9 to curve the apex end of the cone inwardly but centers the opening at the apex end that the advantagesand It will be obviousthat the "and' arrangement of the 'light coat of transparent hard apparatus will render the apex end ofthe cone l A l ja hard drying material, such as enamel or the like and the material is preferably of-a contrasting color than thatof the cone, for identification purposes. However, any coloring matter may be used and thence a applied over the coloring matter.
In Figures 13 and 14, I have illustrated a cone provided with identification means, and for thatpurpose, the outer shell has a plurality ofopenings 20 arranged in rows about the circumference thereofy adjacent to its apex end, 'the openings being of diamond shape ifi` the form shown, but it will be obvious that they may beof any apl propriate shape. The intermediate shell may be of a diiferentcolor than the outer shell, so that I it can be readily seen through the 'openings 20. However, I have shown a lining strip 2|v between the intermediate and outer,shells, and the'stripr is ofcourse of a different color 'than that of the outer shell, so that it likewise can be`readily seen through the openings 20 for purposes, as will be apparent.
It is thought from the foregoing description novel features` ofthe invention will be readily apparent. l
It is to be'understoodythfat changes may be made in the construction. and in the combination several parts, provided identification that such changesfall appended claims.
