SPOOL, BEAM, OR THE LIKE Filed Feb. 15, 1929 Patented May 3, 1932 UNITED STATES PATENT OFFICE 'WILLIAI A. TRA'VEB, OI PROVIDENCE, RHODE ISLAND, ASBIGNOB '10 FRANKLIN PROCESS COMPANY, 01' PROVIDENCE, RHODE ISLAND, A CORPORATION OD! ISLAND SPOOL, BEAM, 03. THE LIKE Application filed February 15, 1929. Serial No. 340,202.

This invention relates to improvements in the construction of s ools, beams, reels or the like for use in trans er processes or for dyein and similarly treating yarn, thread and ot er textile materials.

One object of the invention is to provide a construction for a spool, beam or the like which will be light in weight yet strong and durable to withstand rough handling in the processes in which it is used.

Another object of the invention is to proride a construction for a spool, beam or the like in which the heads are securely attached to the barrel to insure against their becoming loose from the pressure of the material wound thereon or from the strains imposed in use.

Another object of the invention is to provide a construction for a spool, beam or the lilre which may be manufactured at low cost 0 render it economical for use in large numers.

Further objects of the improvement are set forth in the following specification which describes a preferred form of construction of i the invention as illustrated by the accompanying drawings. In the drawings:

Fig. 1 is a longitudinal view of the improved spool or beam;

Fig. 2 is an end view of the same; and

Fig. 3 is an enlarged sectional view of the spool taken on line 33 of Fig. 2, showing the method of attaching the heads to the barrel.

The embodiment of the invention herein shown is in the form of a j ack-spool or beam and comprises a hollow barrel 2, flange-like heads 3, and bearing-hubs 4. The tubular barrel 2 may be made of any suitable lightweight, durable material such as sheet-metal or fiber, and when intended for use in dyein the walls of the barrel 2 are perforated with circumferentially arranged apertures to allow the egress of fluids forced through its central opening. The ends of the barrel 2 are reduced slightly in diameter for a short distance to form shoulders 5 which function for a urpose as later explained.

he heads 3 may be made in one piece, but

as here shown they comprise two parts, a relatively thin disk 6 and a separate annular flange 7. The disks 6 may be cut or stamped from sheet-metal and for certain uses holes 16 are drilled or punched therein adjacent their peripheries to provide means for holding the end of the yarn, thread or other material wound on the. spool. The annular flanges 7 may be cast, or punched from heavier stock, and are tapered 1n cross-section toward their peripheries. Radially-dis osed holes are drilled through the flanges and threaded to receive studs for a purpose to be later explained. The disks 6 and flanges 7 are permanently secured together by rivets 8 and the resultant structure is axially bored to form a tapered hole 9 which adapts the head 3 to be mounted on the reduced end of the barrel 2 with its side abutting the shoulder 5, previously mentioned.

The hubs 4 are constructed with an axial bore of slightly less diameter than the opening in the barrel 2 and are formed with circumferential flanges 11 provided with countersunk holes 12 for receiving screws 14 which secure them against the outer faces of the flanges 7. The inwardly projecting portions of the hubs are of tapered or frustroconical section at 15 to correspond to the taper of the axial holes 9 in the heads 3.

In assembling the parts of the spool, the

heads 3 are placed on the reduced ends of the barrel 2 against the shoulders 5. The tapered portions 15 of the hubs 4 are then forced into the ends of the barrel 2 and the flanges 11 secured fast to the heads 3 by means of the screws 14. As the hubs 4 are forced into the bore of the barrel 2 their tapered portions act in the manner of a wedge to expand the ends of the barrel outwardly to bind them in the tapered holes of the heads 3. When the screws 14 are tightened a firm, secure joint is effected between the parts to rigidly and fixedly hold the flanges or heads in place.

By the novel arrangement of the parts as above described, a. rigid and serviceable spool or beam is provided which is practically proof against damage, breakage or distortion in use or from rough handling. Furthermore, the heads are so mounted on the barrel and reinforced by the end hubs and flanges that they will remain in perpendicular relation to the axis of the barrel and parallel with each other under the pressure of the yarn mass wound on the barrel. The layers or coils of yarn are thus prevented from becom- 5 ing displaced'or disarranged as the mass is built up on the spool. It will also be observed from the foregoing that the improved jackspool or beam is extremely simple in construction, so that it may be manufactured at 10 relatively low cost.

While I have herein shown and described a preferred embodiment of the invention, various modifications may be made in the structure and arrangement of the parts of the device without departing from the spirit and scope of the invention. Therefore, without limiting myself in this respect, I claim:

1. A spool or beam comprising a tubular barrel, relatively thin disks having axial openin s fitted to the ends of the barrel, an-

nular anges of greater'thickness than the disks overlying the outer faces of the latter and having tapered bores for receiving the ends of the barrel, hub-members having annular tapered portions inserted into the ends of the barrel to wedge the terminal portions thereof outwardly into binding engagement with the tapered bores in the flanges, said hub-members having peripheral flanges abuttin the faces of the annular flanges, and means or fastening the flanges together and to the disks to fixedly secure all the parts in permanent relationship.

2. A spool or beam comprising a tubular 35 barrel having its periphery reduced in diameter at its ends to provide annular shoulders, disks having axial openin s fitted to the reduced end portions of the barrel in abutting relation to the shoulders thereon, annular flanges overlying the outer faces of the disks and provided with tapered bores for receiving t e ends of the barrel, hub-members having tapered portions inserted into the ends of the barrel to wedge the reduced portions 45 thereof into binding engagement with the bores in the flanges, said hub-members having peripheral flanges abutting the faces of the annular flanges, and means connecting the flanges to effect a permanent joinder of the parts.

In testimony whereof I hereunto aflix my signature.

WILLIAM A. TRAVER.
