SPOOL.

Application filed October 26, 1923. Serial No. 671,014.

To all whom it may concern:

Be it known that I, HERBERT O. TAFT, a citizen of the United States, and a resident of Burlington, in the county of Ghittenden and State of Vermont, have invented a new and Improved Spool, of which the following is a full, clear, and exact description.

This invention relates to spools and par ticularly to spools of the type known as jenny spools and has for an object to provide an improved construction wherein the end disks are firmly held in place without injuring the body of the spool.

Another object of the invention is to provide a spool with a removable end capable of being firmly locked in position when in use, the arrangement including countersunk retaining members positioned in the head and spaced from the central opening of the body or core.

A still further object is to provide in a jenny type spool, a series of countersunk portions in the head or end disks and means mounted therein co-acting with the clamping bars for firmly holding the head against removal and also against independent rotation.

In the accompanying drawing- Figure 1 is a view partly in elevation'and partly in longitudinal vertical section, disclosing an embodiment of the invention.

Figure 2 is an end view of the structure shown in Figure 1.

Figure 3 is an elevation of one of the end disks removed.

7 but also to project into the extensions 5. This will prevent any independent rotation of the disks while permitting the clamping members or nuts 9 to properly function. It will be-noted that the clamping members or nuts 9 are not only provided with a flange 8 but an elongated body or shank 10 which is internally threaded for receiving the threaded end of the clamping bar 11. In the accompanying drawing, three clamping bars 11 have been shown and, consequently, three clamping members 9 but it will be evident that more or even less might be used without departing from the spirit of the invention. As there is appreciable tension on the clamping members 9, it is necessary to provide a flange 8 and also in view of this same tension, it is necessary that the device shall have a comparatively long body 10 to accommodate the threads 12. If the flange 8 was left off, the tension would be so great as to break or wear away the end pressed by the body whereas if the body 10 was cut off and the. clamping members made as thick as the flange, the threads 12 would not be suflicient to withstand the tension. For this reason a sufliciently strong flange is provided for taking care of the tension. The flange 8 in addition to acting as means for resisting the tension, acts also as lockmg means by reason of the fact that it projects into the notches 6. Each of the flanges 8 is preferably provided with one or more apertures 13 in order to'receive a proper wrench whereby the device may be rotated and the parts brought under the proper tension.

It will be noted from Figure 1 that the rods 11 are countersunk almost entirely in the body 1 so that when tension is brought to bear thereon the pressure will be almost directly against the shoulder 14 whereby a very rigid and strong connection is presented. i i

What I claim is A spool, comprising a body having a longitudinally arranged central bore and a tubular projection at one end whereby a shoulder is provided, an end disk having a bore fitting said tubular projection and also fitting flatwise against said shoulder, said tubular projection having an arc-shaped notch, said end disk having a countersunk portion registering with said notch, a nut fitted in said countersunk portion and projecting into said notch, and a rod screwed into said nut for locking said end disk in place whereby the end disk is locked against independent longitudinal movement and independent rotary movement.
