JACOB D. KINGSLAND, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO ALFRED D. ZEIGLER, OF SAME PLACE.

SPOOL OR BOBBIN.

SPECIFICATION forming part of Letters Patent No. 659,306. dated October 9, 1900.

Application inea January 9,1900, serial No. 354.A (No model.)

To all whom it may concern/.-

Beit known that I, JACOB D. KINGSLAND, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Spools or Bobbins, of which the following is a specification.

This invention relates to spools or bobbins, and aims to provide an improved bobbin especially applicable as a core for newspaperrolls, although myimprovements can be employed for any purpose for which articles of the general class known as spools o r bobbins can be used.

Heretofore various bobbins have been provided for newspaper-rolls, the bobbin being designed to carry the roll of newspaper, especially during unwinding of the paper as it is fed to the printing-cylinders of a multiplecylinder press. Such bobbins are made of paper or iron tube reinforced internally and provided with a notch, so that the spindle or shaft holding them in the press can be inserted through the bobbin and the roll can be engaged by a projection entering the notch to effect or control the revolution of the roll of paper. 'Ihe weight and expense of metal bobbins have been considerable, and difficulty has been vfound in obtaining a simple and strong paper bobbin.

My invention aims to provide a bobbin Which can be formed wholly or partially of paper or other light cheap iibrous materialn which may be molded or built up from such material, as by successive windings of asheet of paper and the cementing of each convolution to the next and which shall be sufficiently strong for its use and still light and economical.

To this end in carrying out my present invention I provide certain improvements which will be hereinafter set forth as applied to a bobbin or core for rolls of newspaper.

In the accompany ing drawings, which illustrate certain adaptations of my improvements, Figure l is a perspective view of a bobbin embodying the preferred form of my present invention. Fig. 2 is a fragmentary axial section thereof cut on the line 2 2 of Fig. 3. Fig. 3 is a cross-section thereof cut on the line 3 3 of Fig. 2. Fig. 4 is a side elevation of the preferred form of my improved reinforce and iiller. Fig. 5 is a perspective view of the filler or attacher alone. Fig. 6 is a fragmentary axial section showing a moditication, and Fig. 7 is a similar view showing another modification.

Referring to the drawings, I will first describe in detail the preferred form of my invention, as illustrated in Figs. 1 to 5, inclusive, in which A represents the body or core proper, B the reinforce, and O the notch.

The body A consists of a paper or. other fibrous, cemented, molded, or built-up tube or cylinder, and the reinforce B consists of a suitably-strong reinforce .having a portion of smaller diameter than and fitting within the end of the body. The reinforce may be of any suitable cast, molded, or built-up construction, but is preferably of cast-iron. f

According lo one feature of improvement the body A is imperforate and continuous and the notch C is formed in the reinforce inwardly of the body, so that the body is not weakenedat its edges. The notch is preferably of less depth than the maximum diameter of the bushing, terminating at its outer side flush with the inner face of the body and extending thence into the tubular part of the bushing.

According to another feature of improvement the bushing has a projecting annular iiange a of not greater diameter than, and preferably of the same diameter as, the exterior of the body, which flange ts directly against the ends of the body and protects these ends,forming a contin nous guard therefor. The bushing also has a small body b, which projects within and is fixed to the interior of the core-body A and is integral withv the flange a, and the notch C is formed partly in the flange and partly in the body b, extending entirely through the latter radially and only partially through it axially and extending only partially through the ange, so that the notch .is surrounded by connected material at its periphery and at its inner end. The bushing B is formed with annular head c, which fits the interior of the core A, and an outwardly-facing shoulder d, between which and the ange a the body has a wide annular groove e, into which the notch C opens. Diametric-ally opposite the notch orat some other suitable point the body has an axially-extending or other suitably-formed projection f, preferably of less length than the width of the groove e and shown as formed integrally with the bushing.

According to the preferred form of my invent-ion the bushing B and body A are connected together by an intermediate attacher D of improved construction. This preferably consists of a divided ring of suitable molded, fibrous, or built-up material, preferably paper, which [its in the groove e of the bushing and is attached to the inner face of the body A, preferably by cementing. The attacher preferably slightly exceeds in diameter the diameter of the fiange c and fits snugly between the shoulder d and the fiange d and is sufficiently compressible to permit it to be forced tightly into the bodyA. It also is preferably cemented to the bushing, its slit or cutaway portion g passing over the projectionf of the latter. Preferably the notch C also extends through the attacher D at E, in which case the slit g and project-ion f insure that the portion of the notch in the attacher shall coincide with that iu the bushing.

In use the core-bodies A may be made in any suitable manner, the bushings B may be cast, and the attachers D may be cut from suitable tubes,and thc parts can be assembled by springing the attachers over the shoulder c of the bushing after preferably first cementing the groove e ot' the latter, whereupon cement can be applied to the exterior ofthe attacherand the combined attacher and bushing can be forced into the end of the corebody. This will make a very strong connection, insure strength at the ends of the core-body, and give a smooth cylindrical metal surface h within the bushing for receiving the spindle or shaft on which the roll is to be carried. The inner end of the bushing maybe tapered at i to facilitate insertion of a spindle through the core. If the cement between the attacher and bushing should fail to adhere, the intel-engaging projectionsfand cut-away portions g will prevent rotation of the bushing within the attacher. Adhesion between the attacher and the core-body may be relied on when these two parts are made of paper or other easily-cemented material. The resulting core or bobbin will have great strength and lightness, will be economical in first cost, durable in use, and convenient of manipulation.

It will be seen that my invention provides improvements which can be readily and advantageously availed of, and it Will be understood that the invention is not limited to the particular details of construction set forth as constituting its perferred form, since it can be employed according to such modifications as circumstances or the judgment of those skilled in the art may dictate Without departing from the spirit of the invention.

One modification is shown in Fig. 6,in which the reinforcing function of the attacher is largely availed of by forming it as a continuous ring of thick molded or otherwise suit ably-formed paperorother material D', which is cemented in the core-body A, inwardly of the end thereof, and has cut-away portions g', which receive projections c on the bushing B', shoulders d of these projections engaging shoulders f' on the attacher to prevent separation of the parts. The bushing is here constructed with a liange a and a cylindrical body b', which latter extends inwardly of the core-body A and meets the forward edge of the attacher D'. The notch C is here formed solely in the bushing. The inner end of the attacher is beveled at i'. In this construction the attacher and bushing are assembled. Their exteriors are then coated with cement and they are forced together into the corebody, the attacher insuring retention of the bushing in place.

Fig. 7 shows a modification in which the bushing is a plain cylindrical member, preferably of very strong molded or built-up paper B, which is forced into the core-body A until its outer edge is flush with the edge thereof, the two parts being cemented in this position. The notch C" is here formed in the bushing alone, through which it extends entirely, the body A serving as a top for the notch. This is a simple construction of great strength which can be cheaply made and is convenient of use, giving the advantage of a covered notch without the disadvantage of weakening the edge of the corebody A,which, it will be seen, has in this case, as in those before described, a continuous unnotched end.

What I claim is- 1. In paper spools or bobbins, the body A having a continuous uncut end, in combination with a bushing fixed within the end of said body and having a notch in its outer end within and covered by the uncut end of said body.

2. In paper spools or bobbins, the combination with a body A of fibrous material having an uncut end, of a paper ring fixed within the end of said body and having a notched opening through and covered by the uncut end thereof.

3. In paper spools or bobbins, the combination With a body of fibrous material, of a notched bushing fixed Within the end of said body, and an attacher fixed within said body, said bushing and attacher having intel-engaging provisions holding the bushing in position.

4. In paper spools or bobbins, the combination with a body, of a notched bushing fitting in the end thereof, and a notched attacher fixed in said body and engaging said bushing for holding it in place.

5. In paper spools or bobbins, a body A, a bushing fitting therein, and a split ring surrounding said bushing and fixed Within said body for holding the bushing therein.

6. In paper spools or bobbins, a body A, in

IIO

combination with a bushing B having a notch C at its outer end, and an attacher surrounding said bushing, having a coinciding notch, and fixed Within said body for holding said bushing therein.

7. In paper spools or bobbins, a paper body A, in combination with a metal bushing B fitting therein, and a split ring D surrounding said bushing and fixed within said body, said ring and bushing having interengaging pro` visions preventing their independent rotation, and saiding holding said bushing in position.

8. In paper spools or bobbins, the paper body A, in combination with the bushing B having flange a, notch C, tubular extension b, and groove e, and the paper-attacher D ttingin said groove,havinga coinciding notch,

and fixed Within said body. for holding said bushing therein.

9. For paper spools or bobbins, the im-y my name in the presence of two subscribing 3o witnesses.

JACOB D. KINGSLAND.
