CLOTH ROLL Filed Oct. 1 1953 JNVENTOR. LEONARD M. Eoezas ATTORNEY United States Patent 2,746,693 CLOTH ROLL I'eonard M. Rogers, Mention, Mass assignorto Draper Corporation, Hopetlale, Mass, a corporation of Maine Application October-1, 1953, Serial No. 383,611 '2 Claims. (cram-#74 This invention pertains to cloth rolls such as may be used for winding fabric as it is taken up in a loom, and more particularly, to a part of :such rolls used to anchor or retain an end of the fabric as it is started to be wound on the roll. I

It is an object of the invention to devise a cloth roll,

preferably of metal, which shall be of small diameter,

Steel tubing with the fabric end retaining means integral therewith and produced by a very simple machining step.

Other objects will become apparent from the following more detailed disclosure.

Cloth rolls are employed in looms and other textile machines for use as a core upon which the cloth is wound and may be made from metal or wood. They have means for anchoring the fabric end so as to start winding after which the tension on the material causes it to wrap tightly and thus to become self-energizing to an extent. Such means commonly involves a slot and feather or other extra parts of such nature that the end cannot bedetached or the roll removed until the fabric is unwound. There have been some collapsible rolls used, but they are necessarily of larger diameter and that detracts from the amount of material which can be wound for any given case sincethe outside diameter of the package is definitely restricted.

According to the instant invention a roll of small diameter, that is, one just large enough to have theneeded rigidity is formed from solid or tubular stock, preferably the latter. Such a roll may be machined and provided at its ends for receiving supporting gudgeons and for being driven positively as required. To hold the fabric end and yet permit ready detachment and withdrawal of the roll, anchoring means in the form of pins are preferably integrally formed and are disposed slightly below, or at least, not above the cylindrical surface of the roll. These pins are inclined at an angle such that fabric impaled thereon will be held as the roll is turned in a direction to Wind the cloth thereon. They are preferably produced with a hollow millingcutter which is fed into the roll or tube at the required angle. In effect,

it counterbores the roll leaving at the center a projection or pin. If the roll is a tube or hollow, the milling cutter is fed into the shell thereof and preferably through to the hollow interior at one side, but not into the material at the roll surface at all at the other side. That is possible since the cutter is maintained at an angle such that the pin will incline as required.

The invention will be described in greater detail in following paragraphs wherein reference is made to the accompanying figures of drawing, wherein:

roll of Fig. 1.

Fig. 3 is a section taken at line 33, Fig. 2.

Fig. 4 is 'an end view of the roll.

Fig. 5 is a section similar to that of Fig. 3, but illustrating a modification.

Now referring to "Figs. 1, 2 and 3, the roll 10 showh here as a tube, preferably of standard tubing is cut to length and machined internally adjacent its ends to accommodate bushings 11 and 12 within which gudg'eons or other supports are to be received. At one and preferably both ends, a pin 13 is inserted and fixed, this pin being for the purpose of transmitting driving torque to the roll and for use in releasing and withdrawing the roll from the cloth.

A number of cloth retaining or anchoring means '14 comprise pins 15 and means defining an annular counterbore inset in the material of the roll. There may be as many of these cloth end retaining means as are required. All do not have to be used unless needed. The pins as herein shown are an integral part of the roll itself and are left by the machining operation which results in the counterbored opening 'or recess. A preferred manner of forming the same employs a hollow milling cutter of outside dimension equal to the diameter ofthe counterbored recess while the hollow interior of the tool is of a diameter equal to that of the 'pin, or at least, these figures are accurate when the cutting portions of the tool are considered.

The angle at which the cutter is fed into the roll material, "that is, the angle of projection 'of the pins, is cohsiderably inclined to a radial plane through the pin. It may also be described as directed along a line defining a segment of the tube or roll cross-section, which line is positioned approximately within the middle third of a radius of the tube perpendicular to the segmental line. Thus the pins will incline in a direction to grip the cloth impaled thereon and to hold it more tightly as the roll is rotated; also, when the roll is turned reversely, the pins will withdraw from the cloth thus freeing the roll so it may be pulled endwise and removed. In this way the roll need not go along with the cloth to be returned .but does not enter the material at the opposite side except to form the flat inset surface 17 from which the pin projects.

As shown in Fig. 3, the end of fabric F is pushed over pin 15 so the latter pierces the fabric, this being done with the handle of a pair of scissors or with any other suitable instrument. The fabric may be thus connected to the roll at all or as many of the pins as are required to retain it for the first few revolutions after which the wrapping action will serve to prevent turning of the roll in the cloth.

When a roll of cloth of desired or maximum size has been wound, it is removed in a known way and the roll may be removed by first rotating it reversely to release or withdraw the pins from the cloth and then pulling it from the cloth. To do this a special tool may be engaged with one of the end pins 13.

The form of the invention described to this point con- 3 templates insertion of the roll in a loom or other textile apparatus so its rotation will be directed as in Fig. 3. However, in Fig. 5 a roll 10 is shown in which there are two sets of pins 15 and 18 oppositely directed so ,that no matter how the roll is mounted one set of pins may be used to grip the cloth end.

While the preferred form as herein illustrated utilizes steel tubing, the roll may be solid and may be of wood or other material. If of wood, the pins, of metal, must be driven or screwed into properly counterbored recesses.

Likewise, with a metal roll the pins may be separately manufactured and inset in a convenient manner in counterbores in the metal. However, that form herein shown and described is more economically produced and serves its intended purpose with a maximum of effectiveness.

While it is contemplated that the weaver use some :simple instrument to impale the cloth end on the pins,

details described, but is intended to embrace all variations and modifications thereof falling within the spirit of the invention and the scope of the claims.

I claim:

1. A cloth roll adapted to be rotated and to have fabric Wound thereon comprising an elongated cylindrical member and means forming a part thereof to which an end of fabric may be anchored, but permitting removal of the roll from cloth wound thereon which comprises pins of circular cross section disposed so that they do not project beyond the cylindrical surface of the roll and within counterbored recesses in the roll, said pins being integral with said roll and inclined at an angle intermediate a line tangent to the roll surface and a radial line both of which intersect at the end of a pin, whereby as the roll is rotated in one direction the pins engage the cloth more securely and when rotated oppositely, they withdraw from and release the cloth.

2. A cloth roll adapted to be rotated and to have fabric wound thereon comprising an elongated cylindrical memher and means forming a part thereof to which an end of fabric may be anchored, but permitting removal of the roll from cloth Wound thereon which comprises a plurality of spaced pins of circular cross section disposed so that they do not project beyond the cylindrical surface of the roll, said pins further being centered within counterbored recesses in the material of the roll and inclincd at an angle intermediate a line tangent to the roll surface and a radial line both of which intersect at the end of the pin, whereby as the roll is rotated in one direction the pins engage cloth intentionally impaled thereon more securely and when rotated oppositely, they withdraw from and release the cloth.
