TAKE-UP SPOOL Filed May 15, 1952 F IG. 2.
Zd \Q 2/ INVENTOR 1402 R 4= r J. MURRAY ORNEYS United States Patent TAKE-UP SPOOL Aubrey S. Murray, Watauga, Tenn., I assignor to North American Rayon Corporation, New York, N. Y., a corporation of Delaware Application May 13, 1952, Serial No. 287,508
3 Claims. (Cl. 242-124) This invention relates to a light weight yarn take up spool and to an improved method of manufacture thereof.
An object of this invention is to provide an improved spool that is inexpensive to make and is of balanced and precise construction so that it may be operated at high speeds.
Another object of this invention is to provide an improved spool consisting of a body portion on which the yarn is to be wound and a tubular core portion centered in thebody portion and formed integral therewith out of aluminum alloy by the impact extrusion process.
Still another object of this invention is to provide an improved method for making spools whereby the hollow body portion and a concentric and re-entrant tubular portion are made integral out of an aluminum alloy by impact extrusion.
Other end further objects of this invention will be apparent to those skilled in the art to which this invention relates from the following specification and claims.
In accordance with this invention there is provided a light weight spool adapted to be rotated at relatively high speeds to function as a take up spool for rayon yarn or other thread or fiber. The body of this spool is made of aluminum or aluminum alloys in one piece by a process known as the impact extrusion process whereby the core of the body as well as the outer tubular portion thereof are made in one operation and furthermore the dimensions of these parts .are made of sufiiciently high precision as to yield a spool body that is symmetrical about its axis of rotation. As a result the spool is sulficiently balanced to enable its use at relatively high speeds without excessive vibration.
The body of this spool is made more or less cup-shaped having straight cylindrical walls and having a hollow core member positioned in the center thereof and formed integral with the bottom of the body. All of these parts, namely, the straight cylindrical walls, the bottom and the hollow core member, are produced out of aluminum or aluminum alloys in one operation by the aforesaid impact extrusion process. This process of manufacture yields a body in which the hollow core is centered in the tubular outer walls of the body member and also is integrally and permanently attached thereto by the bottom portion of the body member. This construction therefore provides a simple and inexpensive method of manufacturing spools of high precision which may be used at relatively high speeds without damaging vibrations being encountered.
Further details of this invention are set forth in the following specification, claims and drawing in which briefly:
Fig. l is a view of an embodiment of this spool shown in side elevation;
Fig. 2 is a vertical sectional view taken along the line 2-2 of Fig. 1;
Fig. 3 is a view of the bottom of the spool; and
Fig. 4 is a horizontal sectional view taken along the line 4-4 of Fig. 1.
Referring to the drawing in detail, the spool of this invention is provided with a body portion having straight cylindrical outer walls 10, the bottom of which is made integral with the bottom member 11 and the central portion of the bottom member 11 being made integral with the bottom of the tubular core 12. These parts, namely, the outer cylindrical walls 10, the bottom member 11 and the core 12 are .made in one operation out of aluminum or aluminum alloys by the impact extrusion process. As a result the walls 10 and the tubular core 12 are of substantially uniform thickness and furthermore, these walls 10 and core 12 are substantially symmetrically disposed about the vertical axis of the spool which is the axis of rotation thereof.
The core 12 is made somewhat longer than the walls 10 so that this core extends above these walls and this extending portion 'is provided with threads 13 which are adapted to engage similar threads provided to the hollow knob 14. The bottom of the knob 14 is made to engage the ring shaped flange 15 that is provided to the upper end of the spool. This ring shaped flange 15 is made with a hole in the center thereof so as to fit around the core 12 and it is also provided with a shoulder 16 that is adapted to fit into the upper end of the tubular member 10. When the threaded knob 14 is screwed on the end of the core 12 it functions to hold the ring shaped flange 15 in position on the upper end of the tubular member 10.
The bottom flange member 17 is held assembled to the bottom member 11 by four machine screws 18 that are lodged in the star shaped recess 19 provided in the bottom of the member 17. This recess 19 also functions to receive a suitable clutch member that is attached to the driving spindle upon which the spool is adapted to be positioned during use.
The member 17 is also provided with a recess 20 into which the bottom 11 of the body portion is adapted to be fitted so that the body of the spool is centered upon the member 17 in which position it is held by the screws 18 when the spool is assembled. The bottom flange member 17 is also provided with a thread receiving slit 21 which is adapted to catch and hold one end of the thread to be wound on the spool.
The spool construction embodying this invention results in a spool of high precision in which the outer walls 10 and the walls of the tubular core 12 are each of uniform thickness throughout the lengths thereof. The core 12 is also perfectly centered in the tubular body portion 10. Thus the spool may be placed upon the rotating spindle and rotated at relatively high speeds without vibrations which would be caused by nonuniformity in spool wall structure. These advantages are obtained in this spool construction without resorting to precision machining operations but simply by forming the cylindrical walls 10, the bottom 11 and the central core 12 by the impact extrusion process mentioned above.
While I have described this invention in detail with reference to the preferred embodiment thereof, it is of course not desired to limit this invention to the exact details described and illustrated except insofar as those details are set forth in the claims.
What I claim is:
1. In the method of manufacturing a take-up spool of light weight adapted to be rotated at relatively high speeds of several thousand revolutions per minute and having a hollow tubular body portion adapted to support thread wound thereon with flanges attached to the ends of said body portion and a concentric tubular portion of substantially smaller diameter accurately positioned in the center of said body portion to provide a balanced spool structure adapted to rotate at the aforesaid high speed with a minimum of vibration, the improvements comprising the steps of forming said body portion and said precisely centered tubular portion in one operation by impact extrusion of aluminum alloy so that one end of said body portion and the corresponding end of said centered tubular portion are formed integral in finished form in said one operation, forming end discs for both ends of said body portion, fitting said end discs to said body portion and fastening said end discs to said body portion.
