page_text: LETTERS PATENT to Edward Wyburd Furrell, of Laurence Pountney
Hill, in the City of London, Civil and Mechanical Engineer, for
the Invention of "A NEW OR IMPROVED STAND FOR HOLDING CHARTS AND
OTHER ILLUSTRATIONS."-A communication from abroad by James
Browne, of the City of Toronto, in the Province of Ontario, and
Dominion of Canada, Banker.
Sealed the 22nd June 1875, and dated the 21st January 1875.
PROVISIONAL SPECIFICATION left by the said Edward Wyburd
Furrell at the Office of the Commissioners of Patents, with his
Petition, on the 21st January 1875.
I, EDWARD WYBURD FURRELL, of Laurence Pountney Hill, in the
City of London, Civil and Mechanical Engineer, do hereby declare the
nature of the said Invention for "A NEW OR IMPROVED STAND FOR HOLDING
CHARTS AND OTHER ILLUSTRATIONS," a communication to me from abroad
by James Browne, of the City of Toronto, in the Province of Ontario,
and Dominion of Canada, Banker, to be as follows:-

page_text: end
upright stand, the upper or inside tube being fitted near its upper
with a horizontal cross bar in such a manner that a chart or other illus-
tration suspended from the said horizontal cross bar may be raised or
lowered at pleasure.
The raising is effected by means of a cord or cords passing under a
wheel at the lower end of the sliding tube or bar, and running upwards
and passing over pullies mounted on the upper portion of the upright
stand, their other ends being attached to a counterbalance weight which
is somewhat heavier than the tubes or bars with their horizontal
bar and chart suspended therefrom, and consequently pulls up the
same in the stand.
The lowering is effected by means of a lever and washer fixed at the
bottom of the sliding tubes or bars. On pressing the lever with the
hand or foot against a stop upon the washer the sliding tubes or bars
with their cross bar and chart thereon are lowered, the counterbalance
weight being at the same time raised.
By means of a wedged shaped projection on the inside of the lever
handle pressing against a similar wedged-shaped projection on the face
of the washer at the foot of the sliding tubes or bars and acting against
the face of the upright stand, the sliding tubes or bars with their
cross bar and chart thereon may be retained at any intermediate point
relative to their highest or lowest position in the stand.
To the horizontal bar for carrying the chart or other illustration are
fitted shorter or supplementary tubes or bars, also sliding telescopically
for the purpose of lengthening the said horizontal bar sufficient to carry
a chart of the greatest width.
Upon the horizontal moveable bars for carrying the chart are placed
sliding brackets and hooks from which to suspend the chart.
Brackets are attached to the back of the upright stand for the purpose
of holding charts when rolled up and not required for use.
The great advantage of this stand over the ordinary mode of hanging
charts is, that a chart of any size can be suspended from the brackets
or hooks attached to the cross bar, so that every portion of the chart
can be brought within the scope of the observer's eye. It may also be
used for carrying the black board and other modes of illustration used
by lecturers, and for other similar purposes.

by the said Edward Wyburd Furrell in the Great Seal Patent Office
on the 21st July 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
WYBURD FURRELL, of 9, Laurence Pountney Hill, in the City of London,
Civil and Mechanical Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letter's
Patent, bearing date the Twenty-first day of January, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reigu, did, for Herself, Her heirs and successors, give
and grant unto me, the said Edward Wyburd Furrell, Her special
licence that I, the said Edward Wyburd Furrell, my executors, admini-
strators, and assigns, or such others as I, the said Edward Wyburd
Furrell, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Ise of Man, an Inven-
tion for "A NEW OR IMPROVED STAND FOR HOLDING CHARTS AND OTHER
ILLUSTRATIONS," a communication to me from abroad by James Browne,
of the City of Toronto, in the Province of Ontario, and Dominion of
Cauada, Banker, upon the condition (amongst others) that I, the said
Edward Wyburd Furrell, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Edward Wyburd Furrell, do hereby
declare the nature of the 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 consists of an arrangement of one or more metal bars or

page_text: 1
other, and within (or at the back of) an upright stand mounted or fixed
on a suitable base. The upper or inside bar or tube is fitted near its
upper end with a horizontal cross bar, and operates in such a manner that
a chart, black board, or other illustration suspended from the said cross
bar may be raised or lowered at pleasure.
To the horizontal cross bar are fitted shorter or supplementary bars
or tubes, also sliding telescopically or otherwise, for the purpose of
virtually lengthening the horizontal cross bar, and thereby enabling a chart
of the greatest width to be carried theroby.
Upon the horizontal cross bar, or upon the shorter or supplementary
bars or tubes forming parts of the same, are placed sliding brackets or
rings formed with hooks from which the chart, black board, or other
illustration is suspended.
Suitable brackets are attached to the back of the upright stand
for the purpose of holding charts when rolled up and not required
for present use.
And in order that the said Invention may be fully understood I shall
-now proceed more particularly to describe the same, and for that purpose
shall refer to the several Figures on the Drawing hereunto annexed, the
same letters of reference indicating corresponding parts in all the corre-
sponding Figures.
Figure 1 is a front elevation of one form of the Invention; Figures
2, 3, and 3 are enlarged views of detailed portions of Figure 1; Figure 4.
is an enlarged part side elevation at A in Figure 1; and Figure 5 is a
part side section on line B, B, in Figure 1.
a, a¹, is an upright stand open at the back, as shewn (or hollow
internally (as the case may be) constructed of iron, wood, or any other
suitable material; b is a metal bar (or tube) sliding telescopically and
vertically at the back of (or within) the upright stand a, a¹, and fitted
at its upper end with the horizontal cross bar c, to which are fitted the
shorter or supplementary bars (or tubes) d, d, sliding telescopically by
means of the rings e, e, or other device, so as to virtually lengthen the
horizontal cross bar c, upon which or upon the said shorter or supple-
mentary bars (or tubes) are placed the sliding brackets or rings f, †,
(Figure 3) formed with hooks g, g, from which is suspended the chart,
black board, or other illustration to be exhibited.

page_text: .
By the adjustable action of the shorter or supplementary bars (or
tubes) d, d, a chart or other illustration of the greatest width can be
carried
on the cross bar c, or on the other hand a number of small charts
or other illustrations may be carried simultaneously.
To the lower end of the vertically sliding bar (or tube) 6 at the back.
of (or inside) the lower portion a of the upright stand a, a', is attached
a foot piece (see detailed views in Figures 2 and 3) working in a
slot x formed through the front or face of the lower portion a of the
upright stand a, a', and projecting beyond the said face, as shewn.
Around this projection is placed a ring or washer i formed at its lower
portion on its outer face on one side with a projecting stop piece y,
and on the other side with a projecting wedge-shaped piece z; ; is a
lever or handle fitted and working on a stud projecting from the outer
face of the foot piece h, as shewn, and formed with two arms 1, 2, its
arm 1 resting on the projecting stop piece y, and its arm 2 formed with
a wedge-shaped recession on its inside face corresponding with and
normally in contact with but not producing any pressure upon the
wedge-shaped piece z of the ring or washer i. At the back of the foot
piece h, and near the point of its attachment to the vertically sliding
bar (or tube) b, is mounted the wheel or pulley k round which passes
a cord 3 leading to and over each of the pulleys l, l, which are mounted
on the under side of the top or roof of the back space (or interior, as
the case may be) of the lower portion a of the upright stand a, a¹, as
shewn; the ends of this cord pass down and are attached to a weight m
of sufficient gravity to slightly overcome the combined weight of the
vertically sliding bar (or tube) b with its cross bar c and chart suspended
therefrom.
The whole apparatus is mounted or fixed upon the base n, which may
be of any desirable material or design, and is of sufficient weight to
maintain the superincumbent chart stand and its appendages in an upright
and steady position.
The base n may be formed either with feet or rollers, in which latter
case the chart stand is more easily moved to any desired position on the
floor of a hall or room.
It
The manner in which this Invention operates so as to facilitate the
exhibition of charts or other illustrations may be thus described.
is to be supposed that the vertically sliding bar (or tube) 6 with the

page_text: horizontal cross bar c and its appendages are in their highest position
relatively with the upright stand a, a', and that the foot piece / with its
handle are in their highest position in the slot x, the weight m being
at the same time in its lowest position at the back of (or inside) the
lower portion a of the upright stand a, a¹. The chart or other illus-
tration is now suspended from the horizontal cross bar c by means of the
hooks g, g, and it being desired to lower the same in order to obtain a
nearer and clearer view of its upper portion, the foot or hand is applied
to the arm 1 of lever or handle j, and pressing downwards thereon the
said arm acts against the projecting stop piece y, and thereby lowers the
ring or washer i and foot piece h, bringing down with them the vertically
sliding bar (or tube) b, cross bar c, and chart in the upright stand a, a¹
the weight m being at the same time raised. When the chart has been
lowered to the desired extent by pressing the arm 2 of the lever or
handle j, the wedge-shaped recession on the inside of the said arın exerts
a pressure on the corresponding wedge-shaped projection z of the ring or
washer, and thereby jams the latter against the front edges of the slot
a, and effectually locks the foot piece h with the entire apparatus at the
required point. When it is desired to raise or lower the chart again the
foot or hand is applied to the arm 2 of the lever or handle j which releases
the wedge-shaped piece and allows the free vertical movement of the foot
piece h, with the vertically sliding rod 6, cross bar c, and chart in either
direction, the preponderating weight m raising and the pressure of the foot
or hand lowering the chart or other illustration.
A wheel may be substituted for the lever or handle j, or the locking
may be effected by a screw and washer, or by a ratchet and lever, or by
any other mere modification or device; o, o, are brackets or hooks
carried by a suitable frame p of brass or other material secured to the
back of or to any other convenient part of the upright stand a, a¹. On
the hooks o, o, are placed the charts or other illustrations which are
rolled up and not required for immediate use. In lieu of suspending the
chart by the ordinary mode of rings secured to the upper bar thereof,
self-acting rollers may be employed, the principle of which is, that by
releasing a catch in combination with a spring the chart is neatly
rolled up automatically without the troublesome method of doing it by
hand.

page_text: enlarged detailed portions of Figures 6 and 7. In this arrangement the
upper portion a¹ of the upright stand a, a¹, in Figure 1 is dispensed with
and a framework all of wood or other material substituted, the vertically
sliding tube (or bar) 61, sliding telescopically through a ring in the upper
bar of the framework a¹¹, and passing through the top of the upright
stand a (which corresponds with the lower portion a of the upright
stand a, a¹, in Figure 1), where it is connected with the foot piece h¹,
(seen more particularly in Figures 8 and 10) at the point 9, (Figure 8).
The foot piece h¹ works in the slot a¹ and is formed with a recess on its
outer face. In the centre of this recess is a stud r carrying the washer
to which is secured the lever or handle j¹, as shewn. On the inner
face of the washer ¹ are two wedge-shaped pieces z¹, 21, (see also Figure
9), which normally project into the slot a¹, and are in contact at their
apices with the inner face of the recess on the foot piece ², whilst at the
same time the inner face of the washer ¹ on which the wedge-shaped
pieces z¹, z', are formed is in contact with the front or face edges of the
slot. The counterbalance weight pulleys and cord in this arrange-
ment are similar to those previously described in Figure 1. Supposing
as before that the foot piece h¹ with its washer ¹, and lever or handle j¹,
and the vertically sliding tube (or bar) 6¹, cross bar c¹, and chart or
other illustration are in their highest position, and it is desired lower
the latter by pressing with the foot or hand upon the lever or handle j³,
the foot piece h¹ (with its appendages and chart) is caused to descend in
the slot, the weight m' at the same time being raised in the back
space (or interior) of the upright stand a".
The chart having been sufficiently lowered the lever or handle j¹ with
its washer are turned slightly round on the stud r, which causes the
wedges z¹, z¹, to rise and jam themselves against the front or face edges
of the slot x, and in so doing forces the back flanges s, of the foot
piece h hard against the back face edges of the slot x¹, thereby locking
the apparatus. By turning the lever or handle j' in the reverse direction
the foot piece h¹ is released (owing to the wedges ¹, ¹, returning into
the slot ¹) and the chart raised or lowered again at pleasure.
This Invention supplies a want in public institutions, lecture rooms,
school rooms, libraries, and offices, in the shape of a simple and complete
arrangement for keeping and carrying maps and charts. It provides
also a ready means of exhibiting all kinds of illustrations, and has the
following advantages over all other methods,―

page_text: 1. The easy and simple means of raising or lowering the horizontal
cross bar, whereby every portion of a chart or illustration is brought
within the scope of an observer's eye.
2. Accommodation is provided for new charts and for charts of all
sizes. Charts not immediately required are placed, rolled up, and pro-
tected from dirt, on the rack at the back of the stand.
3. By the sliding brackets and hooks on the horizontal cross bar pro-
vision is made to receive charts mounted either in the ordinary way or
on the self-acting rollers.
4. Several charts can be suspended from the horizontal cross bar at
the same time.
5. In school rooms, lecture rooms, libraries and offices, whilst being
used for charts it can be made to carry a black board, and by the simple
addition of letter clips to the sliding brackets can be used for exhibiting
drawings, tracings, photographs, and other objects of illustration.
6. The stand is an elegant and portable piece of furniture occupying
but little space and easily worked by a lady or child; it provides com-
plete accommodation for illustrations of all kinds, whilst the walls are
preserved from damage and disfigurement by nails and unsightly and
inefficient arrangements for receiving maps.
Having now described and particularly ascertained the nature of the
said Invention, and the manner in which the same is or may be used
or carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured to
me by the herein-before in part recited Letters Patent is,-
First. The general arrangement, construction, and use of an upright
stand fixed on a suitable base in combination with one or more metal
bars or tubes sliding vertically and telescopically (or otherwise),
and with a horizontal cross bar, substantially as and for the purpose
herein-before described and illustrated by Figures 1 and 6 of the
Drawing.
Second. The application and use of a foot piece working in and pro-
jecting through a slot in the upright stand and fitted with a washer and
lever or handle in combination with the vertically sliding bar or bars
(or tubes) and with pulleys, cord, and weight, substantially as and for

page_text: the purpose herein-before described and illustrated by Figures 1, 2,
3, 4, and 5, or by Figs. 6, 7, 8, 9, and 10, on the accompanying
Drawing.
Third. The application and use of shorter or supplementary bars
or tubes to the horizontal cross bar, substantially as and for the
on the
purpose herein-before described and illustrated by Figure 1
accompanying Drawing.
Fourth. The application and use of sliding brackets or rings and
hooks to the horizontal cross bar, substantially as and for the purpose
herein-before described and illustrated by Figures 1 & 3* on the
accompanying Drawing.
Fifth. The application and use of brackets or hooks secured to any
convenient part of the upright stand, substantially as and for the pur-
pose herein-before described and illustrated by Figures 1 and 6 on the
accompanying Drawing.
In witness whereof, I, the said Edward Wyburd Furrell, have
hereunto set my hand and seal, this Twenty-first day of July,
One thousand eight hundred and seventy-five.
