Nov. 13, 1934. G. A. A NDEiQSON COP OR QUILL Filed July 20, 1951 IIIIIII Patented Nov. 13, 1934 UNITED STATES PATENT OFFICE to Lewis R. Smith, receiver of the Apco Mossberg Corporation, a, corporation of Massachusetts Application July 20, 1931, Serial No. 551,925

1 Claim.

My present invention is a novel and improved metallic quill or cop such as is utilized to hold the filling for the shuttles of looms, and includes a novel method of making same.

Heretofore, in the manufacture of quills or cops it has been customary to utilize a metallic stem with a cone portion applied or fitted thereto, usually by rivets, lugs, or extra portions to hold the cone and shaft together. My present method,

however, includes novel means of uniting the cone and shaft by forming the cone with a plurality of grooves or recesses, or, if desired, threads, thereupon assembling the same on the shaft, and thereupon expanding the metal shaft to flow the metal of the shaft directly into the recesses or threads of the cone.

A further object of my present invention is to provide an all-metal quill. Formerly, wooden quills were used and it was necessary to paint the 0 cone portion with metallic paint. My invention, utilizing an all-metal quill throughout, insures longer usefulness and life to the stem, and facilitates the method of manufacture.

A still further and important feature of the 5 present invention consists in the provision of a metal quill which will constitute a portion of the electric stop motion mechanism, automatically stopping the loom when the quill is empty and cooperating with the usual feeler fingers of the electrical stop mechanism and circuit. This is particularly important where fine spun yarn is utilized, especially in weaving silk and rayon cloths.

Another important feature of the present invention consists of the stem head or pulley being covered with rustless steel cap, thus preventing the head or pulley of the stem from wearing out when coming in contact with the springs in the shuttle.

Referring to the drawing illustrating a preferred embodiment of my invention,

Fig. 1 is a plan view of the complete quill;

Fig. 2 is an enlarged cross-sectional view on the line 2-2 of Fig. 1;

Fig. 3 is a cross-sectional view on the line 3-3 of Fig. 2;

Fig. 4 is a view of the cone before application to the stem;

Fig. 5 is an end view of the cone;

Fig. 6 is a view of the metallic stem, and

Fig. '7 illustrates the process of flowing the metal of the stem into the interior threads or recesses in the cone.

As shown in the drawing, my improved quill 55 includes a thin metallic stem portion designated at 1, having the usual series of grooves 2, 2 for the purpose of retaining the thread wound thereon as applied to the outer surface, the rim 4 on the pulley end or portion 9 of the stem I preferably thus dovetailed slightly in the corresponding head or pulley portion of the stem 1, and is, furthermore, secured in position by a metallic washer 5. Preferably the entire stem 1 is of rustless metal, as Well as the rim 4.

In Fig. 4 is illustrated the cone 10 of appropriate diameter to fit over the stem 1 and with a series or plurality of interior or threaded grooves 11, 11 in the outer yarn retaining grooves 12. Preferably, also, the cone 10 has a series of grooves 14 into which the corresponding portions 15 from the stem 1 are forced to flow during the method of manufacture, to be explained.

As shown in Fig. 6, the cone 10 and stem 1 are assembled and, thereupon, a punch 20 of appropriate diameter is forced through the stem 1, simultaneously forcing flow and interlocking the thin metal of the stem 1 with the cone 10, rim 4, and washer 5, giving an intimate interlocking therewith. This method, I believe to be distinctly new and I wish to claim the same herein broadly. 80

It will thus be seen that I have devised a novel and improved method of forming a metallic cop utilizing, if desired, a metal cone 10 and firmly interlocking the same by my novel process of forcing the metal into grooves, recesses, or threads. Furthermore, by thus forming an all-metal cop I can utilize the same in an electrical stop mechanism for conducting the electric current and as a part of the circuit therein.

My construction prevents breakage, insures long usefulness and life to the cop or quill, and enables the same to be manufactured at a minimum of expense, and permits speed in manufacture.

I claim: I

As an improved article of manufacture, an allmetal cop or quill, comprising a relatively thin metallic stem and a relatively thick metal cone, and means interlocking the same into a substantially rigid unitary structure, both stem and cone having a plurality of exterior grooves formed therein, and a pulley portion comprising two rustless metallic members cooperating to form the pulley, and to interlock the stem and cone.
