VENDER-SHAFT.

Specification of Letters Patent.
Patented N ov. 15, 1921.
Application le'd ctober 22, 1920. Serial No. 418,776.
To all whom 'it may concern Be it known that l, learns l-l. Barren, a eitizenof the United States, residing at Saratoga Springs, in the county of Saratoga and State of New York, have invented -an Improvement in WinderShafts, of which the following is a specification.
This invention relates to a winder shaft and more particularly to an improved construction of collapsible winder shafts upon which rolls of paper are wound after being manufactured, the `object of the invention, like that in other types of collapsible shafts, being to make it possible toremove the shaft from the roll of paper after the paper has been wound thereon. 'lhe collapsible shaft made in accordance with my present invention is so constructed that it may be employed to wind the paper directly there on or t0 receive a cylindrical core upon which the paper is wound and in either use to be as readily fixed in place and removed from the roll as required. ln carrying out the invention the collapsible shaft made in accordance therewith is preferably provided with a longitudinal groove in which there is tted a segment shiftable to position therein and non-removable therefrom so that the face of the segment may be made to conform to the surface of the shaft to make tho same cylindrical; 0r the segment may be moved and thereby shifted a predetermined distance within the shaft so that the face ofthe segment is depressed appreciably below the surface of the shaft to decrease its diameter to the required extent to disengage the roll or core and to thereby make the roll or core readily removable from the winder shaft, and the collapsible Winder shaft made in accordance with my invention will be hereinafter more particularly described.
ln. the drawing:
Figure 1 is an elevation and partial. central longitudinal cross section of a collapsible Winder shaft made in accordance with this invention.
Fig. 2 is a transverse cross section showing the segment in that position in which the face conforms to the surface of the shaft.
Fig. 3 is a similar view showing the position the segment assumes when moved to place within the shaft.
Fig. i is a partial central longitudinal cross section showing the parts in the position as illustrated in Fig. 2, and
Fig. 5 is a view similar to Fig. 1l showing the parts in the Fig 3.

position as illustrated in Referring more particularly to the -drawing, lthe body of the winder shaft is indi- Acated at 10, and as will be understood may be made of any suitable material. This body portion of the shaft is provided with a longitudinal groove 11. rlhis groove is of a predetermined width and depth and the faces defining the sides of the groove are preferably parallel for a predetermined and relatively short distance as indicated at 12, while those portions of the faces defining the sides of the groove extending from the side portions 12 are undercut as indicated at 13 and the bottom portions of the faces dening the sides of the groove are parallel as indicated at 14:. The base of the groove which is illustrated at 15 is substantially at the center of the shaft. In the base 15 of the groove and at predetermined intervals l provide recesses 16. At one end each re cess is preferably circular and at the other side the faces defining each recess are preferaoly tapered at different angles as indicated at 17 and 18 for the purpose to be hereinafter indicated.
adjacent the ends of the shaft, I may provide axle sections indicated at 19 adapted to be `iournaled in suitable bearings, and one of these may be provided'with a lug 20 and the other at its extremity with a square end 21 to receive a crank handle when it may be necessary to turn the shaft manually.
l also employ a segment 22. The face of this segment is made to conform with the cylindrical surface of the shaft, and the side edges of the segment are parallel and of the same extent as the faces 12 so that these edges of the segment are in contact with the vfaces l2 when thesegmentis in that position in which the face thereof completes the cylindrical continuity Aof the shaft as is indln suitableV positions and corresponding'in number with the number of recesses 16 provided in the shaft, as hereinbefore described, l employ a number of transverse ribs 23. Each of these ribs extends across the inner face of the segment and is securedl thereto by rivets 24 or otherwise, and the ends of cach rib are tapered to the same angle as the undercut faces 13 dening portions of the sides of the groove in the shaft so that these ends of the transverse ribs contact with these undercut surfaces 13 when the segment is in the position shown ycated'at 28 and that at the other end at 29.
In the slot'28 there is a pin 30 having a screw threaded shank by which it isconnected to the shaft, While similarly in the slot 29 there is a pin 30 having 'a screw threaded shank 31 for securing the same in position in the shaft, these slots and pins being employed to limit the longitudinal movement of the segment in both directions as Will be readily understood. Furthermore, the segment is shifted from one end position to the other end position or vice versa, or to any intermediate position by the use of a suitable tool which is furnished With the shaft.
As will now be understood the Winder shaft, as hereinbefore described, may be employed to Wind paper directly thereon or to be placed Within a core upon Which a'roll of paper is to be Wound and in so doing the segment is movedlongitudinally of the shaft to position as shown in Fig. 2. Y TWhen the'paper is to be Wound directly'on 'the shaft the parts thereof, of course, are made to assume the position shown in Fig. 2, but, for example, if the paper is to be ivoundon a core the core may be placed over the shaft before the segment is forced to position, and'by moving the segment from right to left, as shown in the figures of the drawing, the surfacesof the transverse ribs will first be caused to ride on the inclined faces 16 and -thenon the inclined faces 17 so that the shaft may the shaft may be readily removed either from the core or from the roll of paper.
I claim as my invention: 1. A collapsible shaft comprising a cylindrical body having a longitudinal groove therein, a segment member adapted to fit the outer portion of the said groove, and a `plurality of transverse ribs secured to the inner surface of the segment member and extending beyond the same,vvith the ends tapered to fit undercut portions of the said longitudinal groove in the said cylindrical body, the base of the said groove being of the same Width as the base of the said transverse ribs. Y
2. A collapsible shaft comprising a cylindrical body having a longitudinal groove therein, with the faces defining the vsides of the groove having outer parallel portions, intermediate undercut portions, and inner parallel portions, Ya segment member of the same Width as the outer portion of the said groove, and a plurality of transverse ribs secured to the underside of the said segment member and extending beyond the same, with the ends tapered to conform to the undercut portions of the faces defining the y Walls of the said groove, with the bases of the said transverse ribs of the same length as the Width of the inner portions of the said longitudinal groove in the cylindrical body member.
3. i collapsible shaft comprising a cylindrical body having a longitudinal groove therein, with the faces defining the sides of the groove having outer parallel portions, intermediate undercut portions, and inner parallel portions, a segment member of the saine Width as the outer portion of the said groove, and a 'plurality of transverse ribs secured'to the under side of the said segment member and extending beyond the same, with the endstapered to conform to the undercut portions of the faces defining the Walls of the said groove, with the bases of the said transverse ribs of the same length as the Width of the inner portions of the said lonv gitudinal groove in the cylindrical body member, the base of the said longitudinal groove having transverse recesses therein with inclined faces for coacting With the transverse ribs to determine the position of the segment lrelatively to the surface of the cylindrical body.
