F b. 10, 1925. 1,525,751 J. A. LAMOTTE CHUCK FOR WINDING CORES Filed Jan. '7, 1924 Patented Feb. 1Q, 1925.
UNITED STATES JOSEPH ARTHUR LAMOTTE, OF RHINELANDER, WISCONSIN.
CHUCK FOR WINDING CORES Application filed. January 7, 1924. Serial No. 684,853.
To all whom it may concern:
Be it known that I, J osnrH ARTHUR LA- MOTTE, a citizen of the United States, residing-at Rhinelander, in the county of Oneida and State of \Visconsin, have invented certain new and useful Improvements in Chucks for Winding Cores, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to devices for association with the ends of tubular cores whereon paper and other sheet stock is wound for shipment, storage, and dispensing, the chucks being provided for support ing and reinforcing the cores at their ends and for attaching them to a supportingshaft on which they are mounted while stock is being woundthereon and unwound therefrom. Thesecores usually are of paper or cardboard stock. 1
It is an object of the invention to provide improvements in; the type of chucks disclosed by United States Letters Patent No. 1,180,955, April '25, 1916, to Edward L. Stuck, in order to overcome difliculties experienced in the use of that type of chuck, to decrease thefnumber of parts, and generally to afforda chuck that is more eflicient and reliable in use and easier to associate with and disassociate from the cores. More particularly, the invention provides an expansible member, for disposition inside of a core and gripping and reinforcing it, so arranged that it cannot be driven too far into the core, and a unitary core-bushing and shaft-collar member so arranged that, when driven into the expansible member, it will expand the latter against the wall of the core.
When considered in connection with the description herein, the characteristics of the invention areapparent from the accompanying drawing, forming part hereof, wherein an adaptation of the invention to a core of paper or similar ,material isdisclosed, for purposes of illustration.
Although" the disclosures herein exemplify what now is considered to be a preferable embodiment of theinvention, .it is to be understood that it is not the intention to be limited necessarily thereto in interpretation of the claims, as modifications and adaptations Within the limits of the claims can be made without departing from the nature of the invention.
' Like reference characters refer to corresponding parts in the views of the drawing, of which- Fig. 1 is a longitudinal section of the device in association with a core and shaft;
Fig. 2 is a view of the bushing and collar member;
Fig. 8 is a view of the expansible member; Fig. l is a sectionon the line H, Fig. 1; and
Fig. 5 is an end view of the sleeve in a core. 1
In the drawing, A designates a tubular core of the type commonly used in wound paper or other sheet stock and B a shaft such as used to support the core while stock is being wound on or unwound therefrom.
An expansible member 6, which is the sleeve of the chuck, is arranged to be disposed in an end portion of the core. The
sleeve is of approximately cylindrical shape,
it preferably is made of sheet metal and tensioned to contract slightly, it is knurled or otherwise roughened on its outer surface as shown at 7 to prevent its slipping in the core, and its outer edge or marginal portion is turned outwardly as an annular flange 8 constituting an abutment to contact with the end edge of the core and prevent it from being moved too far into the core. The sleeve is split by a wedge-shaped keyway 9 extending from end to end and having greater width at its outer end than at its inner. The side walls of the keyway are formed by turning the material of the sleeve inwardly to afford flanges 10.
A chuck member cooperates with, the sleeve to expand it and to afford means for supporting the core and connecting it to the shaft. This member includes a bushing 11 arranged to be inserted into the sleeve and to have the shaft disposed therein, an abutment 12 arranged to contact with the flange 8, and a collar 13 having therein set-screws 13 arranged to hold the member on the shaft.
The portion of the bushing that extends into the sleeve has two slots or grooves 14 extending from its inner end towardthe collar, and a key 15 is located between the slots or grooves. The key is wedge shape and of less width at its inner end than at its outer. It is arranged to be moved into the keyway and to expand the sleeve. This expansion is caused by side walls 16 of the tion With its flange 8 in abutment with the core end. The chuck member theiilis driven into the sleeve until its abutment contacts with flange 8, and the sleeve is expanded by theside walls 16 of the key against the inner surface of the core. T he flange 8 prei vents the sleeve from being forced too far into the core while it is being inserted and wvhi-le the chuck member is being driven thereinto. After the two devices thus have beenassociated with the core, the shaft can,
be passed thereinto and connected to the devices by the set-screws.
. When it is desired to remove a device from v a core, the chuck nen'iber is pulled outwardly ,ironi the sleeve, and the sleeve then withdrawn. If the chuck member otlei's unusual resistance to outward pull, t can be loos eiied bytapping with a. hamii'ier against the collar; and, it it is found ditl'icult to pull out the sleeve, it too can be loosened by tapping with a hammer against the flange S.
The device includes only two separable parts the chuck member and the sleeve andv they can be associated with and disas sociated from a core without employment of special tools, a hammer oulvbeing vrequired in some circumstances to disconnect the parts and perhaps sometimes in dr ving in the. sleeve and chuck member. Thedevice not only constitutes a support for the core and a means for connecting it to a supporting-shaft, but it also affords a reinforcement for the end portion of the core.
Having thus described my invention, what i I claim as new, and desire to secure by Let.-
ters Patent, is
