SPECIFICATION forming part of Letters Patent N 0. 782,942, dated February 21, 1905.

Application filed March 5, 1904. Serial No. 196,702.

To all whom it may concern; Y 7

Be it known that I, FREDERIO B. WOOD, a resident of the city of Providence,in the county ofProvidence and State of Rhode Island, have invented certain new and useful Improvements in Spools or Reels; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to spools on which may be wound wire or yarn principally for use in the wire trade or textile mills.

The object of my invention is to provide a spool very simple in construction that will be practically indestructible, extremely light in weight, and inexpensive to manufacture.

Spools when heavily laden with wire are liable to accidental dropping as well as to careless handling. When wound with yarn and used in the mill, they receive extremely rough usage, and great strength is consequently required for withstanding injury. While'strength is an obvious necessity in such spools, it is of importance that they be as light as is consistent for the uses intended. In addition to the strength required to withstand the rough handling it is also found in practice that great pressure is brought to bear against the heads, having a tendency to crowd or force them off of the ends of the barrel. To withstand this latter strain, I have devised means whereby a natural lock is formed on the ends of the body or barrel, so that the greater the pressure to force these heads off the tighter they are locked and bound in place.

Another essential feature of my invention is the construction of the tubular barrel of corrugated metal instead of making it of plain stock. By this construction a number of important advantages are obtained, the principal of which being that the strength and rigidity of the barrel is greatly increased, thereby allowing a much thinner stock to be used and the weight proportionally to be reduced. Then, again, by corrugat-ing the working face of this barrel and leaving the ends plain a natural shoulder is formed against which the inner face of the heads may rest. The rough surface of the corrugations catch and retain the ends of the threads when yarn is wound thereon, and the scores or grooves in the barrel form anatural guide for the knife which is used to strip off the waste threads from the spool when the yarn has been unwound therefrom.

Vith these and other advantages in view the invention consists of certain novel features of construction,combination,and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 shows my spool in elevation. Fig. 2 is an enlarged sectional view showing one end of the spool and illustrating my improved manner of binding the heads in place. Fig. 3 shows a portion of the corrugated drum with the end left plain, forming a shoulder. Fig. 4 shows this plain end as cut out, forming a plurality of dovetailed wedges. Fig. 5 is a sectional view of one end, showing these dovetailed ends turned up in the position they take when the head is locked in place. Fig. 6 is a sectional end view on line 6 6 of Fig. 3, showing the corrugations in the tubular barrel. Fig. 7

shows the wedging-plug, which is forced into i the end of the tubular barrel. Fig. 8 is an enlarged section of the head, showing the beveled opening which receives the locking wedge-shaped ends of the tubular barrel.

Referring to the drawings, 1 l are circular disks which form the heads or ends of the spool. These disks may be constructed of any suitable material; but paper fiber is preferably used, as it is found to be much more satisfactory for withstanding the shocks and strains these heads are submitted to without splitting, bending, or breaking. Each disk has a hole through its center, said hole being outwardly beveled at 8, as illustrated in Figs. 2 and 8. This beveled portion is for the purpose of receiving and retaining the dovetailed ends of the tubular barrel. The body or bargral therewith, ashoulder formed by the correl 2, onto the ends of which the heads are rugations at the unction of the plain and the fixed, is preferably constructed'of metal and made in a tubular form, and while a plain barrel may be used for this purpose 1 preferably employ the corrugated barrel for reasons above explained. \Vhen the metal which forms the barrel is crilnped or corrugated, a plain portion 3 is left on each end thereof to be inserted into the heads. The raising of the surface of this metal by crimping or corrugating forms a natural shoulder 4: to the plain portion, against which the inner face of the heads may rest. The stock on the ends of the barrel may be left plain, or it may be slit to facilitate spreading the ends, or cut out, so as to form a plurality of dovetailed fingers, as illustrated at 5 in Figs. 4c and 5.

At 6 is the locking-plug, preferably made of wood or fiber. The barrel portion 7 of this plug is made to fit tightly into the end of the tubular barrel. The outer end or head of this plug is made somewhat larger and joins the body of the plug by a slightly-tapered portion 9.

The assembling of the parts of this spool or reel is extremely simple and can be done very rapidly and without the aid of skilled labor. All the tools necessary to do this work is an ordinary press, which may be worked by either foot or power. The operator takes a prepared tube or barrel, and slips a head on either end until it rests against the shoulder a. A plug 6 is then inserted into each end of the tube and the whole submitted to the action of the press, which forces the tightly fitting plugs into the tube, spreads the dovetailed fingers out into the beveled portion 8 of the hole in the head, and the final pressure sets these dovetailed fingers down into the fiber and into the beveled portion of the plug and the spool is completed.

It is obvious in my improved construction that by opening the ends of the tube out into the counterbored portion of the head and holding them there by the beveled portion of the plug any outward strain or pressure on the head simply has a tendency to force said lingers down deeper into the plug and automatically bind or lock the whole more tightly together. It will also be seen that the shape of the dovetailed lingers, which arecountersunk into both eorrugated portions for the purpose of preventing the heads from being forced onto said corrugated portion, said heads, and means for securing them to said uneorrugated portion of the barrel.

2. In a spool or reel, a tubular corrugated body having plain or uncorrugated ends all made in one piece, a shoulder formed on the plain surface by raising the surface on the corrugated portion, heads fitted to said plain ends their inner faces resting against said shoulders and means for expanding the ends of said tubular body to prevent the heads from coming off.

In a spool or reel, a tubular corrugated body having plain or uncorrugated ends, all made in one piece, said plain ends being slit to allow for expansion, a shoulder formed on the plain surface by raising the surface on the corrugated portion, heads fitted to said plain ends their inner faces resting against said shoulders, said heads being provided with central counterbored holes, and a plug having a beveled portion arranged to be driven into the ends of said tubular body to expand the stock into the counterbored portion of said heads.

4. In a spool or reel, a corrugated tubular body having plain or uncorrugated ends, a shoulder formed by the corrugations at the junction of the plain and the corrugated portions, heads fitted on the plain portion of the barrel to rest against said shoulder, said heads being provided with counterbored holes, and a plug having a beveled portion arranged to be driven into the tubular body and expand the ends of the same into the counterbored portion of the heads.

5. In a spool or reel, a corrugated metal body or barrel having plain or uncorrugated ends, the corrugated portion of said barrel forming. a shoulder at each end against which the heads of the spool may rest, a head being provided with central counterbored holes, said heads being fitted onto each end of said bar rel, and a plug to be driven into said tubefor expanding the ends of said barrel into said counterbored portion of said heads.

6. In a spool or reel, a body or barrel, corrugations on a portion of said body only, the ends of said body being left plain or uncorrugated, a shoulder formed by the corrugations at each end at the junction of said corrugated and uneorrugated portions, heads fitted on the plain portion of the barrel to rest against the shoulder formed thereon, said heads being provided with counterbored holes, and a plug to be driven into said barrel for expanding the ends of the same into the counterbored portion of the heads.

7. In a spool or reel, a body or barrel, corrugations on a portion of said body only, the ends of said body being left plain or uncorrugated, a shoulder formed by the corrugations V and uncorrugated portions of the barrel, the
