Description
. July 25, 1944. G. w. LANE- WINDING SYSTEM Filed Sept. 11, 1942 INVENTOR, Geo rye M Zane,
ATTORNEY.
Patented July 25, 1944 WINDING SYSTEM George W. Lane, Clifton, N. 3., assignor to Van Vlaandercn Machine Co., Paterson, N. 1., a corporation of New Jersey Application September 11, 1942, Serial No. 457,986
4 Claims.
This invention relates to systems for winding flexible material, as fabric, the same being also referred to in my application filed September 11, 1942, Serial No. 457,985. The chuck of the improved system comprises coaxial driving and driven clutch members rotative independently of each other and one having a socket portion receiving, and the other a plug portion projecting into, one end of the core and said socket and plug portions respectively having humps projecting in radially opposite directions. The core being flexible I take advantage of that quality by causing the driven member inclusive of its hump to hold said core end distorted from its normal form and a part thereof thereby displaced into the range of rotation of the hump of said portion of the driving member. Preferably, the socket portion and plug portion are elongated transversely with the long transverse axis of the plug portion exceeding in length the short transverse axis of the socket portion, whereby to provide each portion with two opposite humps so that the core end will be gripped at diametrically opposite points; and if they are substantially elliptical they will provide broad area contact surfaces thus to avoid indenting or otherwise marring the core end-though of course such surfaces may be present regardless of the particular form of said portions. Preferably, also, the construction should be such that the driven member supports the core end and hence the core in coaxial relation thereto, whereby to attain uniformity in the winding. The construction in any case is such as to facilitate entering and removing the core from the chuck, as where as usual successive windings on different cores are to be eiiected for delivery of the wound masses to the selling trade.
In the drawing,
Fig. 1 shows the preferred form of the system, associated with means to rotate the driving member and with an idle chuck, the view being mainly in longitudinal section;
Fig. 2 is a section on line 2-2, Fig. 1; and
Figs. 3 and 4 show other forms, with the plug portion and core in transverse section and the socket member in elevation.
Referring, first, to Fi s. 1 and 2:
a is the mentioned core.
The driving member of the chuck comprises the part I and the spindle 2 existing as a unit, the part I havingthe socket portion la, here formed transversely elliptical and hence elongated, with its center a: coincident with the axis of said member.
The driven member of the chuck has a transversely elliptical and hence elongated plug portion 6 within saidsocket portion. The driven member is coaxial with the driving member, being Journaled on the headed stud of the latter,
and its transversely elongated portion '6 also has its center at 1:.
I to less than the thickness of the core end when eithermember is turned toward the position in which the major axis of one is perpendicular to that of the other.
when the core end has been introduced to the said groove the transversely elongated plug portion .of the driven member, inclusive of its humps at 8a, maintains said core end transversely elongated and so distorted from its normally circular state as shown in Fig. 2 (incidentally thus holding the core end and hence the core itself centered with respect to the chuck), whereby parts of the core end exist displaced into the range of rotation of humps, in eflect existing at lb, of the driving member. Preferably the driven member projects somewhat from the driving member and is tapered toward its own free end thus to facilitate entering the core to the chuck whereupon, due to the distortion, said core end will be held against rotation relatively to the driven member as well as centered.
The mentioned broad area contact surfaces of the two members are at lb and 6a.
In the form shown by Fig. 3 the driving member has the socket portion, as 9, and the driven member the plug portion, as l0. But each has only a single hump. Thus the socket portion has a single hump at 9a and the plug portion, which is elliptical in form, has a single hump at Illa. In this form the core will be somewhat eccentric with respect to the chuck axis at since the center of the plug portion (i. e., the center of both its long and short transverse axes) is at 2 In the form shown by Fig. 4 the driving member has the plug portion, as l2, here oval in form, and the driven member the socket portion, as l l. The hump of the driving member is at lZa and the hump of the driven member at Ila. In this case the core will be centered with respect to the chuck, its axis being coincident with the axis a: of the chuck.
In Fig. 1 the core is shown supported at its is splined to the arbor at 4, being normally urged to the right by a spring 5. At It is a hand-wheel fast to the arbor, which latter is to be driven by slip-friction transmission means as in my said application; by the hand-wheel the attendant can manually turn the arbor and hence the driving member when necessary.
The core is readily assembled with the two chucks by entering one end, withthe core in tilted position, to the active chuck and utilizing it to displace that chuck against the tension of the spring until the other core end can 'be alined with and entered to the idle chuck. On the driving member of the active chuck being now rotated, with the driven member subjected to resistance to rotation, as by the fabric, the core and driven member will be rotated as a unit.
Having thus fully described my invention, what I claim is:
1. A winding system comprising supporting structure, a flexible substantially tubular core onto which to wind flexible lengthy material, and a chuck journaled in said structure and consisting of driving and driven members rotative independently of each other and one having a socket portionreceiving,andtbeotheraplug portion proiecting into, oneendbt the coreand said socket and p111! p rtions respectively having humps projecting in radial directions relatively opposite to each other, said portion or the driven member, inclusive 01' its hump, holding said core enddistortedfromitsnormaliorman'dapart thereof thereby displaced into the path of rotation 01' said hump 01' said portion of the driving member.
2. The system set forth in claim 1 characterined by said humps respectively providing broad area contact surfaces presentedto the core adiacent said end.
' .3. A winding system comprising supporting structure, a flexible substantially tubular core onto which to wind flexible lengthy material, and a chuck Journaled in said structure and consisting of driving and driven members rotative independently and coaxially oi each other and one having a transversely'elongated socket portion receiving, and the other a transversely elongated plug portion projecting into, one end of the core, said portion or the driven member holding the core end distorted to transversely elongated form and with its long transverse axis, as said end is so distorted, exceeding in length the short transverse axis of said portion or the driving member.
4. The system set forth in claim 3 characteria'eld by said portions being substantially elliptic GEORGE W. LANE.
