Improvements in Devices for Stretching and Fastening Page-cords
Round Columns or Pages of Printing Type.
A communication from abroad by HUGO STAEDING, of Kiel, in the Kingdom of Prussia.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn in the County of Middlesex, Civil
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 is designed to stretch and fasten page cords round columns or pages
of type for printing purposes.
Figure 4 shows, on a smaller scale than the foregoing, a galley and a column or
page of type, the latter tied up by a page cord which is fastened by the aforesaid
device.
The ends of the page cord a are passed round the posts bb, and are inserted
between the discs or rollers cc, which are provided with flat surfaces d d for that
purpose.
The discs are provided at one end with toothed wheels e e, which engage one with
the other, and are protected by a guard on the plate or frame
9.
A spring h, attached to the outside of b, engages through a slit i the teeth of the
gearing e, thus holding the discs in position.
Figure 2 shows the position in which the cord a may pass between the discs, because
the flattenings being opposite one to another sufficient space is given for the cord to
pass. To produce a tension of the cord as is necessary to bind fast or tie up a column
or page of type, a key is put into the hole k of the disc c, which is adapted to push or
pull aside the spring thereby releasing the gearing. By rotating the discs, the cord
may now be drawn tight. As soon as the key is drawn out of the hole, the spring h
again engages the gearing and the cord is thereby secured.
In Figure 4 a column or page of type is shown. Here the length of the device is
equivalent to the width of the column; if however the latter should be wider than
the device, a plate 1 (Figure 3) may be laid under the device, the length of which
corresponds to the width of the column of type.
In the example represented on the drawing, the pulleys are flattened symmetrically,
so as to secure an equal binding or stretching of the cord round the type column.
This invention is not limited to the particular form or shape shown on the drawing,
as other shapes or modifications may be readily substituted without departing from
the nature of the invention. For example, the flattening may be made on one of the
discs only, or, instead of the flats, the discs may be provided with an eccentric
arrangement, or one of the discs may be replaced by a step of any form or
section. For augmenting the friction between the discs their surfaces may be
roughened or serrated, and other arrangements and modifications can be inade
without changing the nature of the invention.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to ime by
my foreign correspondent, I declare that what I claim is :-
1. The herein described device or modifications thereof for stretching and

page_text: fastening page cords round columns or pages of type for printing purposes, with
the several parts combined and arranged substantially as set forth.
2. In a device of the kind described, the combination of the frictional rollers or
discs cc between which the page cord is inserted, the toothed wheels e e on the
end of said discs by which they can be synchronously rotated to tighten or release
their grip of the cord, and the spring / adapted by engaging the teeth of one of
said wheels to hold the cord in the required degree of tension, substantially as
described.
