Improvements in Wooden Rollers, Spindles, and the like.
I, ARNOLD GOODWIN of 56 Sumner Street, Southwark, in the County of
London, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
This invention has reference to rollers, spindles, and the like (hereinafter called
rollers) that are made hollow and of wood and are provided at the ends with
metallic caps that fit into and surround the hollow ends of the rollers for the
purpose of preventing the rollers from splitting and also for forming bearings
to fit the axles upon which the rollers are to be mounted for use. In such rollers
it has heretofore been usual to fix the caps in place by screws or other separate
fastening devices, but considerable difficulty has been experienced, especially when
the rollers are liable to become alternately wetted and dried, in keeping the caps
always securely in place. Now my invention has for object to obviate the disad-
vantage above referred to and it has reference for this purpose to a construction of
roller of the kind referred to with metal caps so constructed and applied as to
render the use of screws or other separate fastening devices unnecessary as I
shall now explain with reference to the accompanying drawings wherein Figs. 1, 2
and 3 show one end of a roller with cap according to this invention, in central
longitudinal section, side elevation and end elevation respectively.
1 is a wooden roller, built up it may be in sections as well understood. Each of
its end portions is coned or tapered as shown at 1" and provided at a suitable distance
from the free end with an annular groove 2. The metal cap therefor comprises
two concentric tubular parts 3 and 4 connected by an annular plate 5; the inner
part 3 being adapted to fit within the hollow end of the roller and the outer tubular
part 4 being made conical as indicated by dotted lines in Fig. 1, and provided at
its free end with an inwardly projecting annular flange 6 the internal diameter of
which is such as will admit of the cap being placed in position within and over the
end of the roller. When this has been done the outer tubular part 4 is caused by
external pressure to close tightly around the coned end of the roller so that its
flange 6 will extend into the annular groove 2 therein, as shown in full lines in the
drawings. For this purpose there is forced over each cap, which is made of metal,
such as soft brase, that will flow under pressure, an annular die such as indicated
in dotted lines at 7 in Fig. 1, and the internal diameter of which is such as will
cause the said outer tubular part 4 to close tightly around the end of the roller
and cause the flango 6 to enter the groove 2 therein. In this way the cap is firmly
secured in place and cannot become detached even if the end portion of the roller
should contract slightly. The caps at the two ends of the roller may conveniently
be closed simultaneously around the roller ends. The inner part 3 has a square or
other suitably shaped hole 3 therethrough to fit a correspondingly shaped axle or -
bar for supporting the roller when in use.
Rollers constructed according to my invention may advantageously be used for
carrying the rolls of paper used for newspapers and the like. They may also be
used in the domestic mangling and wringing machines.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is':--
1. Protecting and strengthening the ends of hollow rollers of the kind herein

page_text: referred to by tubular metal caps the outer portions of which are provided with
inwardly extending flanges and are closed upon the grooved ends of the roller by
external pressure substantially as described for the purpose specified.
2. My improved roller with metal end caps constructed and applied substantially
as described and shown.
