QUILL OF BOBBIN FOR SILK OR OTHER TEXTILE WEAVING.

' SPECIFICATION forming part of Letters Patent No. 534,768, dated February 26, 1895.

Application filed March 19, 1894.

To all whom it may concern:

Be it known that I, FRANK STONE, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Quills or Bobbins for Silk or ing, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

This invention relates to the peculiar construction of the'quill or bobbin as specified; the object of the invention being to provide a cop-quill for carrying weft thread in shuttles; more especially designed for silk weaving, from which quill the silk or thread can be drawn with great facility and precision; also, to provide a cop-quill having a plurality of spirally disposed guard-strands about its tubular stem, the ends of which strands are buried and secured within the substance or interior of the body.

Another object is to provide a mode of construction by which cop-quills or bobbins having spirally wound strands thereon can be made quickly and economically; the strands properly and securely adjusted thereon and a durable efficient article produced at comparatively small cost of manufacture.

I attain these objects by the construction explained in the following description and illustrated in the drawings, wherein- Figure 1 is a side view of my improved quill. Fig. 2 shows the parts of the body separate. Fig. 3 shows the manner of attaching the guard strand to the tube. Fig. 3 illustrates a method of fastening the end of the strand in a quill having an integral head and stem. Fig. 4 is a longitudinal section of the complete quill. Fig. 5 shows a modification in the head connection. Fig. 6 shows a cross section of the tube at line W W, and of the tip at line to to. Fig. 7 is a cross section at line X X. Fig. 8 shows a modification for the attachment of a strand to the top. Fig. 9 is a view of the complete quill and cop illustrating the delivery of the thread therefrom,

and Fig. 10 is an enlarged section of thequill as provided with an enamel surfacing over the tube and guide strands.

As shown in the drawings, my improved cop-quill or bobbin is composed of the following parts: the head 1 having a spindle-hole through its axial center; the tubular stem or shaft 2; the conoidal or rounded tip 3 closing theend of the tube; and the wire or strands 4 connected with said tip and head and forming a plurality of guards or external ridges spirally about said tubular shaft.

The shaft 2 consists of a straight or slightly tapered cylinder made of wood; or ofpaper rolled into the form of a thin tube and strongly cemented; or of other suitable material, and forming a light, rigid shell with squared ends. (See Figs. 2 and 6.)

The head 1, which may be externally formed of the usual or any desired suitable shape, is provided with an end 5 that fits the lower end of the tube 2, and a shoulder 6 against which the end of the tube is seated, so that when said parts are glued and forced together a firm and rigid attachment is produced.

The tip 3 is made solid, of wood or other suitable material, and is shaped with a rounded or conoidal top and a projecting shank or tenon 7 that fits the interiorof the shaft tube 2, and a shoulder S'that matches the end thereof so as to present a smooth and flush exterior surface. V

A transverse hole 9 is formed through the tip 3 near the base of the oonoid and a small wire or smooth strand 4 is passed through said hole (see Fig. 3) the wire bent downward along the shaft and wound spirally about the cylindrical surface thereof; the two spiral.

strands occupying diametrically opposite po sit-ions on the circle. The ends 10 are securely fastened within the interior of the head or to the endof the shaft where it is connected with the head.

My preferred method for making the quill is as follows: I first separately form the head 1, the tubular shaft 2 and the solid conoidal tip 3, as shown in Fig. 2; then pass laterally through the tip 3 a piece of wire of small gage, (say about No. 30,) or an equivalent strand of suitable material; said'wire being of the required length to make the two spiral guards. After bringing the tip to a central position thereon (see dotted lines Fig. 3) the two parts of the wire are folded down close to the sides of the tip, as indicated in full lines, and small bends or hooks 10 formed at the ends of the strands are looked under the end 12 of the shaft tube 2. The head or end 5 is then, glued and applied to the tube which is forced down against the seating shoulder 6, thereby inclosing and permanently confining the ends of the strands within the head. The strands 4t and tip 3 will then be in position as shown in Fig. 3. After the head has become fixed, glue or suitable adhesive cement is applied to the tenon 7 of the tip 3, its end inserted in the tubular shaft 2, and before the glue or cement has become set the tip is rotated causing the strands 4 to assume a spiral position about the exterior, and drawing the shoulder 8 of the tip 3 firmly against the end 13 of the shaft 2. When the tip has been thus rotated to its utmost limit it is there held and the cement permitted to set and harden, thereby rigidly and permanently attaching the tip, as shown in Figs. 1 and. By this method of construction the Wire strands are drawn tightly against the cylindrical surface of the shaft on the shortest or most direct spiral line that a given length of strand can occupy; and the ends being securely fastened there is no tendency or liability of strands becoming loose or disarranged upon the surface of the shaft. The strands entering or passing through the tip gives an inwardly rounded termination, a smooth connection and a sure attachment at that point; while the ends being buried and clinched within the substance of the body or head are firmly retained and protected so as to offer no objectionable projections or.points on the interior that might otherwise interfere with the unwinding of the cops.

In someinstances it may be desired to make the quill With its head 1 and shaft? integral. In such case the end of the Wire or strand is best entered through the side at the junction of the head with the cylindrical portion, passed down a groove at the side of the central opening and the hooked end buried and secured by looking it into the solid part of the head, as shown at 20 in Fig. 3.

In some instances, when desired, the quill having the spirally disposed strands thereon, is provided with an outside covering of enamel 15 that envelops the guard strands 4, firmly attaches them to the cylindrical surface and fills the crevices between the parts, as at 16, Fig. 10, so as to present a complete unbroken surface following the contour of the exterior form, and protecting the quill from slivering, or from distortion when exposed to moisture.

In Fig. 5 I have shown a modification in structure which provides for making the joint at the end of the tubular shaft 2, by inserting the same. within a recess formed in the head 1. In this case the ends of V the wire strands 4 are passed through side openings to the interior, then carried down within the tube and their ends 10 turned outward and looked under the end of the tube, as illustrated.

By constructing and combining the parts of the quill in the peculiar manner shown and described, I produce a durable, efficient and highly advantageous article that can be manufactured with practical facility and economy.

With the quill constructed as described it is practical to employ quills of much greater length than those ordinarily used for silk weaving, and to thus carry a much greater quantity of weft thread in a single cop, while affording a free and uniform delivery of the thread from commencement to finish of the cop, without liability of frequent stoppages or the making of waste in weaving.

This quill is of especial utility in using double ends, or two-thread silk in the cop; the liability of the threads separating as they run off being overcome thereby, since the plurality of opposite spiral-guards raise the unwinding weft silk from the body and prevents the thread from closing its coils about the cylindrical surface and creating sufficient frictional tension to break the thread as it is drawn off, by the sudden action of the shuttle when thrown across the loom.

I claim as my invention, to be secured by Letters Patent- 1. A cop-quill or bobbin comprising a cylindrical shaft with a connected point or tip-- end, and provided with a plurality of spirally disposed guard strands about its cylindrical shaft, the said strands being laid at positions diametrically opposite each other at opposite sides of the cylinder, the spirals terminating at the bobbin-head, and at the-point or tipend, by the said strand or guard passing directly into or beneath the surface of the body substance without lateral deviation in the spiral of the guard, as set forth.

2. A quill or bobbin havinga solid tip and a strand of Wire passed through said tip, the opposite portions of the strand being'folded downward at the sides and helically wound about the quill or bobbin, and the ends of the strand being attached to the body at or near its head, as set forth.

3. A quill or bobbin composed of a head, a cylindrical tubular shaft, a conoid or rounded tip having a tenon that enters said tube, and a wire strand the central part of which passes laterally through said tip, the two parts of the strand being laid spirally about the tubular shaft, the ends of the wire engaged upon the end of the shaft-tube and the end of said tube being attached to the head to secure the wire permanently thereto, substantially as set forth.

4. A quill or bobbin having a tubular paper IIO Witness my hand this 14th day of March, A. D. 1894.
