'WlNDlNG-SHELL FOR CALlCO, 80c.

SPECIFICATION forming part of Letters Patent No. 267,817, dated November 21, 1882,

Application filed April 11, 1882. (No model.)

of Passaic, in the county of Passaic and State of New Jersey, have invented a new and 1111- proved Winding-Shell for Calico, 850., of which the following is a specification.

My invention relates to the hollow wooden shells which are used for winding long strips of calico, cotton cloth, or other fabric or paper, or similar material into large rolls; and'it consists of a metal casting consisting of a central .portion which has a square passage through it and a surrounding ring or ferrule connected to the central portion by fins, the casting to be forced into the ends ofthe shell for strengthening the same anddor furnishing a metal socket, bushing, or clutch for connecting the ordinary power-shank for revolving the shell.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l isfla central sectional elevation of an ordinary wooden windingshell having my metal bushing and ferrule applied thereto; and Fig. 2 is an end elevation of the same.

A represents the wooden winding shell, which is of the ordinary form and construction and B B represent the castings or bushing applied to the ends thereof. The central portion, a, of the casting or bushing is by preference deeper than the surrounding ring I), and is of an external size equal to ora little greater than the bore of the shell A, and has the square central passage, f, through it, as shown clearly in Fig. 2. The surrounding ring I), which formsthe ferrule part of the casting, is joined to the central'portion, a, by the radial line 0 c, which are by preference made slightly tapering from their outer to their inner edges. The ring D is also made slightly tapering from its outer to its inner edge, as shown in Fig. 1, to facilitate the driving or forcing of the casting into the ends of the shell. The castings will be forced by suitable power into the ends of the winding-shell before the shell isputinto the lathe to be turned up, and suitably attached to the lathe-dogs for turning, so that nishes a clutch for the square shank. The ring b, when the castings are forced into the shell, inclosesand to aconsiderable extentcompresses the portions d d of'the material of the shell between the ring and the central portion, a, of the casting, and acts as a ferrule to those portions, thus adding greatly to the strength and durability of the shell.

In order to strengthen the fins c c and to facilitate the removal of the pattern in the casting of the device, I prefer to re-enforce the fins at the corner where theyjoin the ring I) and central portion, a, as shown at i t in Fig. 2.

Having thus fully described-my invention, I claim as new and desirepto secure by Letters Patent .7

'1. As a new article of manufacture, a combined bushing and ferrule for winding-shells,

consisting of the central portion, a, having a square hole,f, the tapering rim 1), and the tapering fins 0, connecting the rim and central portion together, the said central portion being deeper than the rim, substantially as herein shown and described.

2. The combination, with the shell A, of the casting B, consisting of the apertured central portion, a, the tapering rim 0, and the tapering fins a, connecting the central portion and rim together substantially as herein shown and described, whereby the casting serves the double purpose of a bushing for the shell and means for securing it in a lathe for turning up saidv shell, as set forth.
