I, JOHN WATSON WEBSTER of 41 Mawdsley Street, Bolton in the County of
Lancaster, School Stationer, do hereby declare the nature of my said invention to be
as follows:-
This invention relates to a new or improved method of mounting maps, plans, charts,
and other analogous sheets and consists in mounting the same on rollers disposed on a
board or frame composed of wood or other suitable material of any convenient length.
The rollers are mounted on the top and bottom ends, or thereabouts, of the board or
frame in fixings provided with open or closed ends or bearings. The maps, plans, or
other sheets are attached to the rollers in a continuous length. The rollers are pro-
vided with pulleys and centre pins, and are operated by endless cords, bands, chains,
or other equivalents, which allow of the same being operated in either direction,
vertically or horizontally, at will. If desired the supporting fixings can be secured to
a wall or other equivalents.

A New or Improved Method of Mounting Maps, Plans, Charts, and
other Analogous Sheets, and in Apparatus for Effecting the
same.
I, JOHN WATSON WEBSTER of 41 Mawdsley Street, Bolton in the County of
Lancaster, School Stationer, do hereby declare the nature of my said 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 relates to a new or improved method of mounting maps, plans,
charts, and other analogous sheets and consists in mounting the same on rollers
disposed on a board or frame composed of wood or other suitable material of any con-
venient length. The rollers are mounted on the top and bottom ends, or thereabouts,
of the board or frame in fixings provided with open or closed ends or bearings. The
maps, plans, or other sheets are attached to the rollers in a continuous length. The
rollers are provided with pulleys and centre pins, and are operated by endless cords,
bands, chains, or other equivalents, which allow of the same being operated in either
direction, vertically or horizontally at will. If desired the supporting fixings can be
secured to a wall or other equivalents.
Fig. 1 is a front view of my invention Fig. 2 a sectional elevation through line C¹ D',
and Fig. 3 is an end view of same.
To the board or frame A are fixed the bearings B, in which are mounted the rollers (
provided with the pulleys D and centre pins E. The pulleys D are connected with
the endless cords or bands F, or their equivalents, such as, chains, &c., which allow of
the rollers being turned in either direction at will. To the rollers is connected in
any convenient way the sheet H, containing maps, plans, charts, and others. When
it is desired to change from one map, plan, chart, or other sheet to another it is
effected by pulling the cords or bands F in the requisite direction.
Fig. 4 is a front view of another modification of my invention, and Fig. 5 a side
view of same, wherein the top and bottom rollers Care provided with only one pulley
each; the cord or band F on each side being coupled to the adjustable pulleys I
mounted in the racks J and frames K, to ensure sufficient tension being given to
maintain the correct position of the portion of the sheet being exhibited at the same
time allowing of the sheet being operated in either direction.
To guide the sheet. H to its correct position and prevent the same protuberating the
grooved slides M are provided, of which Fig. is a side view, and Fig. 7 a section
through line A B¹. If desired the grooved slides M can be provided with the slots O
to receive the strips P of wood or other analogous materials across the chart to
distinguish one from the other, or intersect any desired part of the sheet, as well as
that of giving it the appearance of a framed sheet.

page_text: If desired the board or frame A can be dispensed with and the bearings or fixings B
can be secured to a wall, partition, or other analogous places.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The method of mounting maps, plans, charts, and other analogous sheets on
rollers which allows of manipulation in either direction at will, substantially as herein
described.
2. For carrying out the method hereinbefore described the construction and
arrangement of apparatus, applied and operating substantially as described and
illustrated by the accompanying drawings.
