WINDING AND SHIPPING CONE PO KNITTING ANDIIKE MACHINES ANDOA15S THEREFOR.

Specification of Letters Patent.

Patented Feb. 8, 192i.

Application filed September 4, 1917. Serial no. 139,444.

To all whom it may concern:

'Be it known that I, HENRY L. TIFFANY, a citizen of the United States, and a resident of South Dartmouth, in the county of Bristol and State of Massachusetts, have invented an Improvement in WVinding and Shipping Cones for Knitting and like Machines and Caps Therefor, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to cones particularly adapted to have wound thereon yarn,

thread or the like of the commonly known cone winding form and from which yarn or thread is drawn off axially or substantially so to the needles of the knitting machine. 1 p

In order that the principle of the invention may readily be understood, I have disclosed a single embodiment thereof in the accompanying drawing, wherein Figure 1 is a side elevation of a winding or shipping cone embodying my invention; Fig. 2 is a vertical sectional vlew of the upper part of such cone upon an enlarged scale;

.Fig. 3 is a plan view of a cone having my invention applied thereto; and

Fig. 4 is a somewhat diagrammatic representation in section of a deformed tip end of a winding cone having a reinforcing member applied thereto.

Cones adapted to receive or have" yarn or thread wound thereon and, from which such yarn or thread is drawn oif axially when in upright position to the needles of the knitting machine or for like purposes are commonly formedof paper rolled in one or more layers or coils into conical form.

These cones are adapted to be mounted for winding upon tapering arbors of the general shape of'the cones and extending into the same to within an inch or two of the tip end thereof. The ends of these cones protrude over the complete yarn or thread mass.

For a great many years cones were made with a square or open tip end,- being of the so-called square nosed type. In the patent to Charles Gess, No. 986,379, dated March 7, 1911, is disclosed a winding and shipping cone having the apex end bent inward form,- ing an arch accomplishing important re-. sults. The said Gess cone has gone into very extended use and to a very large extent has supplanted the old square nosed cone.

The objectof my invention is to provide means whereby a cone of the'so-called Gess type, the efiiciency of which has been impaired by repeated use, may be rendered perfectly serviceable for further use, and by which all the advantages of the Gess cone may be retained. To this end I preferably provide a cap-like member, which may be of relatively thin but stout paper, thin sheet metal, celluloid or the like. Preferably, however, I employ paper. member may be molded into shape and may thereafter be applied to the desired cone, or within the scope and purpose ofmy in- .vention the paper or other material in an ceiving a heavy blowQ While the effect of such blows upon the tip end of the cone varies, and damaged cones therefore differ somewhat in shape at the tip, I have found that I may mold a paper or like cap member that can be applied to a very large proportion of such damaged cones so as to fit readlly thereon and render them entirely acceptable. I will describe ,one form of my invention.

Referring more particularly to the drawi ing, the shipping and winding cone is indicated at 1, it being markedly tapering as set forth in the said Gess patent, and provided with a single superficial roughening 2.

The cap like The tip end 3 of the cone is inturned as disclosed in the said Gess patent, and the opening 4 in the said tip end may be substantially or in fact entirely closed in the vint'urning process, since my invention is not limited in this respect.

Cones of the generalcharacter to which my invention pertains receive a large package or mass of thread or yarn wound thereon in a comparatively few number of turns 01' coils in each traverse of the yarn or thread from end to end-of the cone. The cone-must therefore be of heavy, stiff paper so as to support the large and heavy package of yarn or thread. Each wound package weighs 1% to 2 pounds and the wound cones are shipped in large wooden cases containing about 150 yarn packages. In transportation the tip of the Gess or round nose cone withstands a crushing pressure far better than the square nose cone, but occa sio'nally the tip of the round nose cone is .damaged or, what is more likely, such tip becomes more or less. impaired in re-use'; In those mills wherein winding and kn1tting are both carried on, it is a common ment, to sort out and classify such used cones, discarding the defective cones, if any theta be, and to sell them to winding mills. Thus it comes'about that the Gess or round nosed cone is repeatedly used and such 'damage as is received by the inturned tip end is more frequently due to such continued reuse than to blows or crushing pressure in transportation.

. In accordance with my invention l[ provide for quick and cheap application to such damaged round nosed or Gess cones of a cap like member 5 conforming to the shape of the unimpaired tip end of the cone as indicated most clearly in Fig. 2 and having a sharply inturnedtip portion 6, which preferably is of just sufficient area and shape to conform to and fit snugly against the usual raw edge of the inturne'd tip end of the cone. Such raw edge is usually of a thickness substantially corresponding to the thickness of paper or other material of which the cone is made.

The cap 5 is intended to be secured to the tip end of the cone and for this purpose I preferably use some suitable adhesive such as gum. The guin or other adhesive should be applied to the entire inner surface of the cap, including the sharply inturned portion 6 so that such cap is tightly secifred throughout its entire extent. Moreover, the material of the cap'is preferably so thin as to merge, as indicated at 7, with the surface of the cone, which is preferably roughened and so that no ridge is presented to the .unwinding yarn or thread. Such construction is more or less diagrammatically indicated. in Fig. 2.

.My invention is not limited in this respect,

but preferably and for the best results 'no ridge should exist at the base of the cap 5 or elsewhere. lif desired, the cone 1, before the cap has been. applied thereto, may be compressed ortreated so as to be slightly reduced in diameter and so as in efiect to form an annular shoulder for the receptlon of the lower edge of the cap 5, thus providing for an absolutely smooth line .of junction between the lower edge of the cap and the cone.

The paper or other material of which the cap is or maybe formed is preferably stiff the tip and this renders more difficult the ap plication of a cap thereto or the retention of the cap in use, since the cone is apt to become battered or subjected to rough treatment in use in mills or transportation. In the case of a cone deformed in use, the tip thereof presents irregular depressions or pockets which receive and retain relatively large amounts of the adhesive which is applied to the inner surface of the cap. Thus I provide localized anchors that serve most, effectively to retain the cap in position.

So far as I am aware, I am the first to apply to a deformed or used inturned end of a cone tip a member.

The cap or reinforcing member of my invention is not intended to be applied to a new or perfect winding cone having an inturned end, but to a winding cone, the inturned end whereof has become deformed or impaired from any cause,'as approximately indicated at 8 on Fig. 4.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic or descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims:

1. As an article of manufacture, a winding cone for knitting machines and the like having a'roughened yarn retaining surface markedly conical in shape to permit the yarn to free itself from the roughened surface when drawn from the end of the cone and having an inturned tip end deformed in use, thereby presenting irregular depressions, an applied reinforcing cap-like member upon the outer surface of the tip end and restor- .ing the original contour thereof and adhesive material between said cap and the cone and received infthe said irregular depressions, thereby providing effective localized anchorings for the cap.

2. As an article of manufacture, a winding cone for knitting machines and the like having a roughened yarn retaining surface markedly conical in shape to permit the yarn to free itself from the roughened surface when drawn from the end of the cone and having an inturned tip end deformed-inv use, an appliedreinforcing cap-like member secured to said deformed tip end and substantially restoring the original contour thereof, and an adhesive lining the inner reinforcing preferably cap-like surface of the cap and received in excess quantities in the localized deformations of the ti 3 end of the cone.

3. s an article of manufacture, a winding cone for knitting machines and the like having a roughened yarn-retaining surface markedly conical in shape to permit the yarn to free itself f'romthe roughened surface when drawn from the end of the cone and having an inturned tip end deformed in use, thereby presenting irregular, spaced depressions, an applied reinforcing cap-like member of thin, stout paper upon the outer surface of the deformed tip and restoring the original contour thereof, and adhesive material between said cap and the cone and receiving said irregular, spaced depressions, thereby providing effective localized anchorings for the cap.

4. As an article of manufacture, a winding cone for knitting machines and the like having a roughened, yarn-retaining surface markedly conical in shape to permit the yarn to free itself from the roughened surface when drawn from the end of the cone and having an inturned tip end deformed in use, thereby presenting irregular, spaced depressions, said tip end having a small axial opening, the rim of which is composed of the raw edge of the cone material, and an applied reinforcing cap-like member of thin, stout paper upon the outer surface of the tip and restoring the original contour thereof, said cap having an inturned rim at its own tip which is co-extensive with and conforms to the said raw edge rim of the tip end of the cone, and adhesive material between said cap and the cone and received in said irregular depressions, thereby providing localized anchorings for the cap.

5. As an article of manufacture, a winding cone for knitting machines and the, like formed of heavy paper rolled into shape and having a markedly conical surface to permit the yarn to free itself when drawn from the end ofthe cone in use, the conical surface being roughened throughout the greater portion of the extent thereof, the tip of the cone being inturned and originally polished and smoothed, but deformed in use, thereby presenting irregular, spaced depressions, the said tip end having a small axial opening, the rim of which is composedof the raw edge of the cone material and an applied, reinforcing, cap-like member of thin, stout paper upon the outer surface of the tip of the cone and restoring the original inturned contour thereof, said cap having an inturned rim at. its own tip co extensive with andconforming to the raw edge rim of the tip end of the cone, and adhesive material between said cap and the cone and received in said irregular depressions, thereby providing localized anchoring for the cap, the lower edge of the cap merging with the surface of the cone face thereof; applying said member to the tip of a winding cone originally inturned and originally polished and smooth but deformed in use, thereby presenting irregular spaced formations; and securing the said.

member in place by the application of adhesive material between said member and the tip of the cone and received in said irregular depressions, thereby providing localized anchorings for the said member and causing the lower edge of said member to merge with the surface of the cone without presenting a ridge whereby a smooth unimpaired surface is presented to the unwinding yarn.

7. That method of restoring, strengthening'or renewing tips of winding cones for knitting machines that have been damaged in use and which cones have a markedly conical butroughened surface permitting the yarn to free itself when drawn from the cone, consisting in providing a cap-like member of thin, stout, paper-like material having a shape rendering it capable when applied to the outer surface of the tip of the damaged winding cone for restoring the original surface thereof; said member having an inturned rim at its own tip substantially ooextensive with and adapted to conform to edge of the cone tip material; and securing the said member in placeby the application of adhesive material between said member and the tip of the cone and received in said irregular depressions thereby providing 10- calized anchorings for said member and causing the lower edge of said member to merge with the surface of the cone without presenting a ridge, whereby a smooth unimpaired surface is presented to the unwinding yarn.

In testimony whereof, I have signed my name to this specification.
