LOOM-SHUTTLE.

SPECIFICATIO N forming part-of Letters Patent No. 444,095, dated January 6, 1891. Application filed March 27, 1890. Serial No. 345.486. (N0 model.)

T0 at whom it may concern.-

Be it known that LABRAM D. EMERY, of Taunton, Massachusetts, have invented a certain Improvement in Loom-Shuttles, of which the following is a specification.

This invention relates to devices for carrying in shuttles cops of the class which are unwound from the inside in the process of weaving; and its principal object is to prevent any disarrangement or entanglement of the cop thread or yarn as it unwinds, and to thereby secure its continuous free delivery without any variation in its tension. Cops of this class have been heretofore carried in shuttles provided with cells substantially rectangular in cross-section, in which cells the cops have been held by laterally-administered elastic pressure tending to transform the original cylindrical shape of the cop into the polygonal shape of the cell. Such a mode of holding the cop necessarily more or less disarranges its tl1 eads, so that in unwinding some of its convolutions pay off less freely than others. By the present invention the cop is enabled to retain its original cylindrical form and all of the convolutions of its thread or yarn remain undisturbed in the positions in which they were originally placed during the operation of winding until they are successively paid off in the process of weaving. The invention consists in inclosing the cop in a cylindrical chamber presenting for impact upon the periphery of the cop a rough surface, such as would be presented by emery cloth or paper or fine sand-paper. The wall of this cylindricalchamber, which for convenience is herein termed the casing, may be of inflexible material, or it may be of flexible material and be inclosed in a rigid external tube. In either mode of employing the invention the casing, by the light pressure of the rough interior surface upon the periphery of the cop, is enabled to exert a suitablystrong hold upon the cop without distorting its form, and to prevent any disarrangeinent of the thread or yarn as the successive convolutions thereof are unwound from the inside. If a casing of flexible material-such as emery cloth or paper-be employed, it may be wrapped around the cop preparatory to placing the cop in a cylinder or tube open at one end, or capable of being opened at one end,

to permit the introduction of the incased cop, and in either case provided with an aperture through which the thread or yarn is paid out in unwinding. The said tube may be modified by dividingitlengthwise and hinging its parts together, so that it may be unfolded to receive the cop. In such case the roughened casing for the cop maybe permanently affixed to the concave surfaces of the parts of the tube, or those surfaces may themselves be so roughened as to subserve the desired purpose. The tube referred to may be pivotally attached to an ordinary shuttle in a manner resembling that in which the ordinary cop-spindle is attached to a shuttle, or the tube may be provided with conical ends and may itself constitute the middle portion of the shuttle. In the latter case provision must be made forintroducing the cop into the shuttle, which may be conveniently done by making one of the ends of the tube detachable.

There are considerable advantages in a cylindrical shut le having spindle-shaped ends, and such a shuttle is made the subject of claim in another application filed concurrently herewith. In the present case it is only intended to be claimed in combination with a cop wrapper or casing having a rough interior surface and a cop of the class which unwinds from the inside in the act of weaving.

In the drawings, Figure 1 is a side view of the cop, partly in longitudinal section, incased in a covering which is represented in section and contained in a cylindrical shuttle provided with conoidal ends,'one of which is detachable, the shuttle also being represented in longitudinal section. Fig. 2 is a transverse section taken through the plane indicated by the dotted line 00 a: on Fig. 1. Fig. 3 is an isometrical perspective of a cop of the kind which is unwound from the inside. Fig. 4 is an isometrical perspective of a cop-covering made of flexible material and having a rough interior surface. Fig. 5 is an isometrical perspective of a cop incased in such a covering as is shown in Fig. 4. Fig. 6 is a side view of a cop-tube divided into two parts hinged together crosswise at one end. Figs. 7 and 8 are respectively a cross-section and a side view of a cop case divided into two parts hinged together longitudinally. Fig. 9 is a side elevation of an ordinary shuttle,to which is pivoted a cop-case provided with a removable cap at one end. Fig. is a top view of the shuttle and case represented in Fig. 0, showing the casein its normal position. Fig. ll. is a central longitudinal section taken through the plane indicated by the dotted line 1 y on Fig. 10. Fig. 12 is a transverse section taken through the plane indicated by the dotted line on Fig. 10.

The drawingsrepresent a cop A of thekind which is intended to be unwound from the inside. A covering 13, having a roughened inner surface I), surrounds the periphery of the cop. This covering may be of flexible material, such as emery cloth or paper, and may be wrapped around the cop preparatory to the introduction of the wrapped cop into the tube or cylindrical shell, which constitutes the outer protecting member 0 of the cop-covering. This outer protecting member may be a tube provided at one end with a removable cap, as hereinafter explained; or it may be made of two parts hinged together, either longitudinally, as illustrated in Figs. 7 and R, or across one end, as illustrated in Fig. 6. hen the hinged construction is employed, the rough-s11 rfaced covering intended for immediate contact with the periphery of the cop may be permanently affixed to or be integral with the concave surfaces of the two parts D (I D (1. (Shown respectively in Fig. 0 and in Figs. '7 and S.) The tube for containing the cop may be provided at one end with a removable perforated cap C, and be pivotally fastened at the other end to an ordinary shuttle E, as represented in Figs. 9,10, and 11. liinally, the tube, which is the outer member of the cop-covering, may itself constitute the cylindricalportion or barrel F of a shuttle provided with conical ends F F as shown in Fig. 1. The conical end F is connected with the barrel F by a telescopic joint, so that it may be withdrawn therefrom to allow the insertion of the barrel F of the wrapped cop.

The removable end F of the shuttle is provided with a curved guide-tube G for guiding, the thread or yarn as it is paid off from the cop in the process of weaving.

\Vhat is claimed as the invention is- 1. A shuttle for weaving provided with a cylindrical cop-easing presenting a rough inner surface and closely surrounding the periphery of a cop of the kind which is unwound from the inside in the process of weaving.

A cylindrical cop-casing for closely surrounding the periphery of a cop of the kind which is unwound from the inside in the process of weaving, in combination with an inclosing cylinder or tube attached to or forming a part of the shuttle.
