WINDING-C ORE Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed January 30, 1907. Serial No. 354,900.

To all whom it may concern:

Be it known that I, JOHN HENRY GATELY, a citizen of the United States, residing at Bellows Falls, in the county of Windham and State of Vermont, have invented anew and useful Winding-Core, of which the following is a specification.

This invention relates to winding cores for the support of roll goods and is particularly designed for use in connection with paper making machines to have paper wound thereon as it comes from the machine.

The invention is more particularly designed as an improvement upon that disclosed in Patent No. 839,378, granted to me on Dec. 25, 1906, and its object is to simplify and chcapen the cost of the reinforces used in connection with the core the same being of such size and construction as to be readily formed from pipes of standard sizes.

Heretofore cores of this character have been provided with reinforcing sleeves disposed therein and notched so as to be engaged by the rotatable drive element, and such sleeves have been formed integral with other sleeves surrounding the core, and in order to produce devices of this character it has been necessary to use special mechanism thereby greatly increasing the cost thereof.

As has heretofore been stated the principal object of this invention is to provide reinforcing means which can be made from pipes of standard sizes and without the use of any special form of machinery.

A still further object is to provide reinforces which completely surround the core so as to absolutely prevent the core from being crushed when in use.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a perspective view of a portion of a core embodying the present improvements; Fig. 2 is a longitudinal section through a portion thereof; and Fig. 3 is a perspective view of a modified form.

Referring to the figures by characters of reference, 1 designates the winding core which may be made of paper or other suitable material and which has one end reduced annularly as shown at 2 so as to receive a sleeve 3 preferably formed of a section of metal pipe of a standard size, although it is to be understood that if preferred this sleeve can be made of fiber or any suitable tough non-yielding material. An interior annular recess 4 is formed within the same end of the core 1 and is preferably of the same proportions as the recess 4 and this recess is adapted to receive an inner sleeve 5 which is also preferably formed of a section of metal pipe of a standard size, although it too may be formed of fiber or other tough non-yielding material suitable for the purposes intended. The two sleeves are held in place by means of screws, rivets or other suitable fastening devices 6 extending therethrough and into the core 1. After the sleeves have been positioned upon the core a notch 7 is cut into the end of the core and the sleeves 3 and 5, said notch-being of sufiicient proportions to receive a projection upon the drive element of the winding mechanism. It will be seen that by providing two separate sleeves 3 and 5 such as herein described the core is reinforced both at the inner and outer edges of the notch 7 and there is no danger of the walls of the notch becoming torn or enlarged as a result of their frictional contact with the drive element. It will be understood of course that if preferred the inner sleeve 5 may be dispensed with. i

It is sometimes desirable to leave the core end free of notches for the reception of the projection on the drive element and in this event the outer sleeve may be constructed and arranged as shown at 8 in Fig. 3. By referring to this figure it will be noted that said sleeve projects beyond the end of the core and the projecting portion thereof is formed with a notch 9 of sufficient size to receive the projection on the drive element. With this form of device the expense incident to the forma' tion of a notch in the sleeve or sleeves and core subsequent to the assemblage of the parts is eliminated, and

the outer sleeve can be notched before it is secured upon the core.

It will be noted that as the sleeves are formed of sections of pipes of standard sizes it is not necessary to make the sleeves of special castings. It will be further more noted that the sleeves are continuous and un broken throughout their extent so as to absolutely reinforce the end of the core against any pressure from any direction.

What is claimed is:

1. A tubular winding core having annular recesses in the inner and outer faces thereof, a continuous interior sleeve of uniform thickness secured within the inner-recess, and a similar but larger sleeve secured Within the outer recesses, said sleeves being separate and the sleeves and one end of the core having registering notches.

2. A tubular winding core having annular recesses in the inner and outer faces thereof, separate pipe sections within the inner and outer recesses, said sections and one end of the core having registering notches, and a fastening device extending through both sections and the core for securing-the sections within the recesses.

3. A tublar winding core having annular recesses in the inner and outer faces thereof, separate pipe sections within said recesses, one of said sections having a notch in its outer edge, and a fastening device extending through the sections and the core to secure the sections within the 10 recesses.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

JOHN HENRY GATELY.
