lUNTTED STATES PATENT FFTCE.
GNTHER PHILIP WILD, OF PHILADELPHIA, PENNSYLVANIA.`
EXPANSIBLE ROLLER.
To all whom t may concern:
Be it known that I, GNTHER PHILIP W'ILD, a citizen of the United States, resid* ing in the city and county of Philadelphia., State of Pennsylvania, have invented a new and useful Expansible Roller, of which the following is a specification.
My invention consists of an expansible roller for winding a web of paper, textile material or similar flexible material, which may be quickly and positively contract-ed to enable it to be withdrawn from the finished roll. l
It further consists of improved means in such roller, whereby the segmental plates which constitute the periphery of the roller are simultaneously moved and parallelism of such plates maintained.
It further consists 'of improved means for locking such segmental plates in their expanded position.
It further consists of improved means for exerting a permanent inward tension upon such segmental plates.
It further consists of other novel features of construction, all as will be hereinafter fully set forth.
The annexed drawings and the following description set forth in detail, one mechani cal form embodying` the invention; such detail construction being but one of various mechanical forms in which the principle of the invention may be used.
In said annexed drawings-Figure 1 represents an axial section of my improved expansible roller. Fig. 2 represents a transverse section o-n the line mma' in Fig. 1. Fig. 3 represents a transverse section on the line g/-y in Fig. 1. Fig. 4 represents a transverse section on the line ee in Fig. 1. Fig. 5 represents a transverse section on the line ca -a; in Fig. 1. Fig. G represents a transverse section on the line b-b in Fig. 1. Fig. 7 represents an axial section of the sliding collar and a portion of a sleeve, illustrating another form of spring for the locking device for the shaft and sleeves.
Similar numerals of reference indicate corresponding parts in the figures.
Referring to the drawings, the reference numeral 1 indicates a shaft, having at one end removable means for rotating it, such as a handle, 2, having its end removably inserted through a diametrical hole in the shaft. Cylindrical sleeves, 3 and t, are located near the ends of the shaft, which is rotatable in Specification of Letters Patent.,
Application filed November 18, 1912.
Patented Sept. 2, 1913.
Serial No. 732,024.
the axial bores, 5 and 6, of the sleeves, and said sleeves have annular flanges, 7 and 8, and one of the sleeves has a hub, 9, which is polygonal or otherwise adapted to be held by a wrench, spanner or similarl tool. Similar intermediate sleeves, 10, without fianges, are located upon the shaft, having axial bores, 1l, their number and spacing being regulated according to the length of the roller and the weight of the roll to be wound upon the same. A cylinder, l2, fits upon said sleeves and is secured to the same by screws, 13. All of the sleeves have enlarged axial bores or recesses, 14, and a series of circular holes, 15, are formed through the sleeves and cylinder,eight of such holes being illust ated at each sleeve. Collars, 16, have a free fit within the recesses in the sleeves, and are secured to the shaft by means of pins, 17, or similar fastening means. A series of round recesses, 1S, are formed in the periphery of each of said collars, and register with the holes in the sleeves and cylinder. Anti-friction balls, 19, have a rolling fit in the holes of the sleeves and cylinder and can drop into the recesses of the collar, the curves of which are described on a larger radius than that of the balls.
A number of plates, Q0, segmental in crosssection, form the periphery of the roller, and have radial guide-pins, 21, slidable in radial bores, 9.2, in the cylinder and sleeves. Four segmental plates and four pins in each set are illustrated, but such number may be varied according to requirements. Collars, 23, have axial bores, 2&1, and are located upon the shaft which may turn within the bores. Two of such collars are here dis closed, but the number of the collars may be varied according to the length of the roller. Each collar has a series of notches, 25, in its periphery, corresponding in number to that of the peripheral sections or plates, and flat springs, 2G, have their ends secured in said notches. Said springs are so tempered that they tend to bend inward, and screws, 27, are secured in the peripheral sections and pass through holes in the cylinder and have their ends screwed into the free ends of the springs, so that the springs will act to draw the peripheral sections inward toward the axis of the roller. A collar, 2S, is secured by a feather, 29, and a groove, 30, to rotate with and slide upon the shaft, and one face of said collar has an annular series of said pins engage two of the notches in the I One end of a coil-V face of the collar 28. spring, 34, upon the shaft, bears against a washer, 35, bearing against the face of the slidable collar, and the other end of suoli spring bears against 'a washer, 36, bearing against the face of the' next adjoining rigid sleeve, so that the pins are normally held, whiley the balls are resting upon the lands or raised portions of the ,recessed or cam collars, in engagement with the notches, preventing accidental unlocking of the parts of the roller as adjusted, while the relative turning of the shaft and sleeves byl additional force, will overcome the tension of. the spring and allow the rounded ends of p the pins to slip out of the shallow notches I that they will all be acted upon by suoli and permit the balls to drop into their respective recesses in the collars, where they will serve as locks.
In Fig. 7 is illustrated another form of spring for the sliding locking-collar 28.V
The collar is in this case formed with a diainetrical groove, 37,' in its face, and a curved intermediate sleeve retain the relative posileaf-spring, 38, is inserted through a slot, 39, in the shaft and has its ends engaging said groove. The spring will hold the c'ollar to rotate with the shaft, and will force the notched face of the collar against the pins.
In practice, the roller is expanded by gripping the hub at one end of the roller against rotation and rotating the shaft by means of the handle, until the balls in the several sleeves are raised out of the round recesses in the peripheries of the collars rigid upon the shaft and rest upon the lands between such recesses. As the balls are thus simultaneously forcedV outward, they force the peripheral sections o-r segmental plates outward, thus givingy the roller its greatest diameter. When the shaft is turned to perform this function, the collar .sliding upon and rotating with the shaft will bring two of its notches or depressions to register with the pins upon the adjoining sleeve, and, by the action of the spring, force said notches into engagement with such pins, thereby locking the shaft and peripherally recessed collars, the sleeves and cylinder, and the peripheral sections together. The web may now be wound upon the roller, which usually is revolved by resting as an idler upon two driven rollers. Then the roll of web is complete and removed from whatever maroller is contracted by again turning the shaft while holding the sleeves and cylinder against rotation, bringing the recesses in the collars to register with the holes in the sleeve Vand cylinder and with the balls therein,
which will then enter such recesses by the peripheral sections being drawn inward by the springs which thus contract theroller so that the latter may be Vwithdrawn from y the roll wound upon it.
The intermediate sleeves, recessed collars and springs may have their number increased or decreased according Yto the length of the roller and the weight of the roll to be wound upon the same, and the number of peripheral sections, holes in the sleeves, recesses in the collars, springs and locking pins and notches may be varied according to the requirements placed upon the roller.
By providing the cam-collars or recessed collars and the balls interposed between suoli collars and the v eripheral sections, and connecting such col ars that they will all move in unison, and by confining the balls so cani-collars in unison, an eXpansible roller is produced in which the expansion and contraction of the sections is simultaneous and parallel throughout the entire length of the roller.
The notched collar and the pins uponthe tion of the sleeves, cylinder and peripheral sect-ions to the shaft and collars, when the balls rest upon the lands or raised portions of the latter when the ro-ller is expanded. l/Vhen the roller is contracted, the balls resting in the recesses of the collar will lock the parts.
Other modes of applying the principle of my invention may be employed for the inode herein explained. Change may therefore be made as regards the mechanism thus disl closed, provided the principles ofconstruc'- tion Set forth, respectively in the following claims are employed.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is Y l. An expansible roller, comprising peripheral sections forming the periphery of the roller, an axial rotatable shaft, sleeves f upon said shaft and formed with axial ref cesses and with holes in the walls of such recesses, means for connecting said sleeves, collars secured upon the shaft within'the recesses in the sleeves and formed with rounded recesses in their peripheries correspondi ing to the holes in the sleeves, and anti-friction balls in such holes and interposed between the collars and the peripheral sections.
