6 Claims. (Cl. 242-68) Patent #l,358,53l granted to Phillip T. Dodge.
The advantages to be derived from my invention are numerous, consisting in part in the ease and simplicity of changing a core to meet the requirements of different machines. In the newsprint industry the ordinary winding shafts core cap mounted upon and protecting the end of the core. The core is usually made of tightly wound paper or other light fibrous material. In other industries, notably the textile industry, the ordinary winding shaft is constructed with a square or other polygonal driving end, and the cores made for this trade are constructed with a matching cap having a polygonal opening therethrough. The purpose ofmy invention is to enable the immediate and easy conversion of a single core to fit either type of driving shaft.
My invention consists in an integral adapting insert which may be applied to or detached from a standard newsprint core. These adapters may be shipped with the core or separately therefrom. Each adapter may be re-used as many times as desired, and likewise the core may be shifted from use with around shaft to use with a polygonal shaft, and vice versa, as many times as desired without ruining the strength and rigidity of the core. This has a distinct advantage inasmuch as it has heretofore been necessary to construct a distinct type of capped core for every type of driving shaft encountered, whereas by means oi.
my invention a single type of core may be supplied to all users of cores together with adapters so constructed as to meet peculiar demands.
Other advantages and objects of my invention will be apparent from the following specification taken in connection with the accompanying drawing wherein like numerals refer to like parts throughout.
In the drawing Fig. 1 is a side view of an adapter embodying my invention} Fig. 2 is an end elevation looking toward the right end of Fig. 1;
Fig. 3 is an end elevation of a capped core having an adapter applied thereto and looking toward the left end of Fig. 1;
Fig. 4 is a cross section taken along line 4-4 of Fig. 3;
Fig. .5 is a partial section corresponding to 5 Fig. 4;
Fig. 6is a partial elevation corresponding to Fig. 3; and
Fig. 7 is a section of Fig. 6 taken along the line 1-1.
My adapter comprises a metallic element preferably formed by stamping the same from a single flat sheet of thin metal. The adapter l0 comprises a flanged cup-shaped member having a polygonal opening at its bottom. This member has an external diameter such that it will fit snugly within a capped core. The core comprises a member H to which a cap has been applied, the cap preferably having an outer flange l2 pressed into the core flush with its outer surface.- An inner flange I3 is preferably seated upon the inner surface of the core ll. Flanges l2 and I3 are joined by a rim l4, making a solid reinforced tip for the core. The adapter is formed with a number of longitudinal, flaring cuts l5 extending inwardly from its open or inner end, thus dividing the wall of the adapter into a plurality of sections'which may be resiliently 'urged inwardly. The inner edge of the adapter is formed with a lip l6 extending outwardly substantially the thickness of flange I3. By reason of the slits IS the inner end of the adapter may be contracted so that it may be slid lengthwise into-the core. The adapter will be held in the core by the lip l6 which snaps over the end edge of flange I3.
The core I I'is provided with a slot within which fits a boss or bulge in the inner flange l3 forming a metal keyway H which cooperates with the key on the driving or winding shaft, thereby preventing the cap from turning upon the core and preventing the key from rupturing the core upon the application of sudden stresses. In order to lock the core adapter against rotative movement within the core cap and also to prevent it 1 from being driven longitudinally of the core, a
The bottom of the adapter is slit along radial lines extending outwardly toward the side walls,
if desired the entire radius may be slit or a. portion thereof may be slit in order thafipolygonal openings of various dimensions may be formed; The triangular flaps 22 thus formed are bent into the adapter and are preferably laid back toward the wall thereof in order that the inner approach to the opening thus formed may have converging guide members. This is preferable in order that a long core may be seated upon a long shaft by a simple sliding movement. The segments 23 left in the plane of the bottom of the adapter are strengthened by reason of the presence of the triangular portions 22, thus forming a very rigid structure which is well braced and is not liable to be ruptured at any point. The opening illustrated is in the form of a square, but it is obvious that a hexagonal or any other polygonal opening may be so formed.
It is obvious from the foregoing that the adapter is easily inserted, and when inserted is not likely to be displaced either longitudinally or rotatively. It is also obvious that a polygonal shaft may be easily passed through the opening fro-m within the core as well as from without, and it is also obvious that the adapter may be removed without difliculty. This latter feature enables the same capped core to be adapted for any standard or unusual type, shape or size of driving shaft, and thus reduces the number of types of cores necessary to maintain in stock and simplifies the production thereof. By reason of my invention, the only variance in manufacturing machinery is in respect to the dies for forming the'adapter itself, rather than in respect to the machines used for applying difierent types of caps to the cores.
The foregoing is a preferred embodiment of my invention and I do not intend to be limited to'the details thereof.. Other modifications, alterations "and substitutions are within the scope of my invention as expressed in the following claims which are to be broadly construed.
What I claim is:
1. A core adapter comprising a cup-shaped member provided with means for engagement with a capped core whereby said adapter is prevented from moving longitudinally and rotatively relative to a core to which it has been applied, the bottom wall of said adapter being provided with a polygonal opening.
2. A core adapter comprising a cup-shaped member provided with means for engagement with a capped core whereby said adapter is prevented from moving longitudinally and rotatively relative to a core to which it has been applied, the bottom wall of said adapter being provided with a polygonal opening, and the side wall of said adapter being provided with a, plurality of slits extending toward said bottom wall from the edge thereof.
3. A core adapter comprising a cup-shaped member provided with means for engagement with a capped core whereby said adapter is pre vented from moving longitudinally and rotatively relative to a core to which it has been applied, the bottom wall of said adapter being provided with a polygonal opening, and the side wall of said Witha polygonal opening, said opening being.
formed by inwardly bent flaps cut in said bottom wall.
5. A core adapter comprising a cup-shaped member provided with means for engagement with a capped core whereby said adapter is prevented from-moving longitudinally and rotatively relative to a core to which it has been applied, said means comprising at least one external projection adapted to engage with suitable depressions in said capped core, and a flanged lip at its edge, the bottom wall of said adapter being provided with a polygonal opening formed by inwardly bent flaps cut in said bottom wall, and the side wall of said adapter being provided with a plurality of slits extending towards said bottom Wall from the edgethereof whereby the flanged lip may be contracted to fit within a bore of substantially the same diameter as the diameter of the bottom wall.
6. In combination, a fibrous tubular core of the type provided with a flanged cap having a keyway formed therein, and a core adapter having a sliding engagement therewith, said core adapter being provided with-means to engage said keyway to prevent rotative movement thereof relative to said core, and being. provided with means to prevent accidental displacement of said adapter from said core comprising projections at
