SHAFT FOR WINDING PAPER ROLLS AND CORES.
Specification of Letters Patent.
Patented Sept. 12, 1905.
A plication filed May 20,1905. Serial No. 261,406.
To all whom it may concern.-
Be it known that I, JAMES H. BAKER, a citizen of the United States, residing at Saratoga Springs, in the county of 'Saratoga and State of New York, have invented an Improvement in Shafts for Winding Paper Rolls and Cores, of which the following is a specification.
My invention relates to a shaft structure adapted for use in paper-mills and upon which a roll of paper may be wound or paper-cores be made and upon which paper cores the paper roll may be wound for shipment.
Heretofore difficulties have been experienced in removing from the roll of paper or its core the shaft upon which the same is wound; and the object of my invention is to construct a shaft whose circumference and bearing-surface can be reduced, so that the shaft-can be readily removed and the shaft then expanded to an initial condition preparatory to winding thereon another roll.
In carrying out my invention the body of -the shaft is longitudinally and oppositely grooved to receive two oppositelyplaced movable segments pivotally connected to the body by rocker-arms that in their initial position hold the said segments, so that the This position is maintained by a removable collar held to the shaft only while the roll of paper is being formed. After the roll of paper is complete and it becomes desirable to remove the shaft the movable segments are actuated in opposite directions and closed down into the grooves to contract the circumference of the shaft, so that it may be readily removed. I prefer to employ a cap fitting the end of one journal and a lever and link device to operate the movable segments. The details of the construction are hereinafter more particularly set forth.
In the drawings, Figure 1 is a plan representing my improvement with the collar in position holding the parts as distended and as ready for paper to be rolled thereon. Fig. 2 is an end view of the parts, Fig. 1. Fig. 3
is a vertical longitudinal .section of my improvement with the collar removed and showing some layers of paper on the shaft and the lever device in position to contract the parts, so that the shaft may be removed; and Fig. 4 is across-section of these parts-without the paper around the shaft. Fig. 5 is an edge elevation of the collar; and Fig. 6 a front elevation of the same, while Fig. 7 is an end view of the body of the shaft without the movable segments; The parts shown in Figs. 1 and 3 are broken across to compact the illustration.
The body portion is composed of the journal ends a 6, adapted to be set into hearings in which the shaft maybe revolved. Between these journal ends there is an intermediate web, which for the main part is of less thickness than the journal ends, and at opposite sides there are fixed segments d 6, between which segments at opposite sides of the web there are channels or grooves. The journal ends, intermediate web, and the fixed seg ments d e are integral. The intermediate web 0 of the body portion is provided with mortises 0, the same being made longitudinally and centrally of the shaft, and the body portion is transversely perforated for the pins 2, which come at the central partsof said mor- .tises, the pins in length agreeing with the extreme diameter of the shaft or body portion.
f and g are movable segments placed intermediate of the fixed segments 01 e and occu pying a position in the grooves between the fixed segments, and the under sides of these movable segments at the ends are shouldered, as shown in Fig. 3. The under sides of the movable segments are also provided at spacedapart intervals with recesses 3, and said recesses are in line-with the said mortises 0, and I employ rocker-bars h, which pass through the mortises and are pivoted on the pins 2, the ends of said rocker-bars being received in the recesses 3 and pivotally connected to the movable segments f g by pins 4. Adjacent ends of the movable segments are provided with apertures 6. In the position of the parts shown in Figs. 3 and at the said rocker-bars are at right angles to the axial line of the shaft and the movable segments are held at their point of greatest distention, and at this point the shaft is circumferentially round and true, and in this position the parts of the shaft are to be held while paper is rolled thereon or while a core for paper-rolls is being made thereon, and for the purpose of holding these parts in position I prefer to employ the collard, (shown inFigs. 5 and 6,) and which collar is shown in position in Figs. 1 and 2 as slipped over the end of the shaft and surrounding the journal end, the ends of the fixed segments (Z c, and in part surrounding the adjacent ends of the movable segments f0, With the internal lugs 2" of the collar coming up against the adjacent ends of the movable segmentsfg and the collar held in position by a set-screw 5, so as to clamp the same to the shaft and prevent any movement of the movable segments. In this position of the shaft and collar the same may be placed in suitable bearings and paper wound thereon or a paper-roll formed thereon, after which the collar is to be removed.
I have shown and prefer to employ a cap it, adapted to fit over one journal end, as a, and to this cap a lever Z is pivotally connected. A link m is at one end pivotally connected to the lever, as shown in Fig. 3, and the free end of the link is bent over approximately at right angles to the main portion and made of a size adapted to pass into'one aperture 6 of one of the movable segments. These parts are shown in position in Fig. ,3, and upon the outward swinging movement of the lever Z with the thrust against the journal end a, to whichthe cap is connected, the link m is pulled upon and actuates the movable segments, pulling one and pushing the other in the direction of the arrows, Fig. 3, so as to close both movable segments down into the grooves of the body, and thus contract the circumference of the shaft, so as to free the grip of the same upon the paper and create a looseness, so that the shaft may be withdrawn from the paper or from the core upon which the paper is wound. After the shaft is withdrawn the lever device is actuated to return the movable segments to their distended position. The collar 71 is then replaced on the shaft, as hereinbefore described, and the lever device may be removed, the shaft then being in condition for repeating the operations of winding paper or of making a core upon which the paper may be wound.
