page_text: I, SARAH CONNOLLY of Blandford Square Regents Park in the County of
Middlesex, Spinster, School Teacher, do hereby declare the nature of this invention
to be as follows:-
The invention relates to the exhibition chiefly of Maps, Pictures, Alphabets and
designs used in teaching.
The apparatus consists of the combination of a wooden or metal frame which is
fixed or suspended in the same manner as any frame usually used in giving object
lessons having slotted holes cut in its vertical sides into which carriers may be
fixed at any required distance from one another by means of projecting heads.
These carriers have attached to them springs or other contrivances for holding
hollow metal, wood or paper tubes or rollers which have inside rollers with springs
or clips for holding the material on which is the lesson or other device. These are
attached or detached through openings in the tubes closed by hinged shutters or
doors. These shutters or doors are self adjusting to allow of the lesson on linen,
paper or other fabric of any thickness being freely wound off the bottom roller on
to the top roller or vice versa by means of convenient thumb-heads. Lessons of
any description may be quickly attached or detached, the size being only limited
by the width of the openings in the tubes and the height of the frame.

page_text: I, SARAH CONNOLLY of Blandford Square, Regents Park, in the County of
Middlesex, Spinster, School Teacher, 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:-
The invention relates to apparatus for the exhibition chiefly of Maps Pictures
Alphabets and designs used in teaching.
The accompanying drawings illustrate the manner of performing this invention.
Fig. 1 is a front elevation of the apparatus.
Fig. 2 is a side elevation showing various modifications in the shape of the
casings and in the manner of securing them to the frame.
Fig. 3 an enlarged sectional view of the roller on which the map or other device
is wound.
Fig. 4 a cross section of Fig. 3.
Fig. 5 the rod to which the map or other device is attached.
Fig. 6 a sectional longitudinal view of the roller which with Figs. 7. 8 and 9.
show various alternative methods of fixing the rod into the roller.
A is a frame of convenient size and adapted to be hung either horizontally or
vertically upon the wall or otherwise This frame consists substantially of the two
parallel bars A provided along their length with slots C which may be arranged
either vertically or horizontally or both vertically and horizontally as shown in the
drawing so that the frame may be hung in either manner as may be needed at the
time.
The frame A carries the casings or tubes B. which contain the rollers, these
casings may be made of metal, wood, paper or other suitable material and may
have any convenient form. In the drawing two forms only are shown, one cylin-
drical, the other square or oblong. For attaching the tubes B to the frame A they
are either themselves provided with fixed pins D or may be held in a pair of clips
such as E connected together by a, bar G to which the said pins are fixed, in this
latter case, the clips are placed at each end of the casing so as not to interfere
with the door F of the latter. A couple of small pins H are fixed. to the casing as
shown in Fig. 1 to prevent the latter from sliding longitudinally in the clips or
falling out therefrom. The door F of the casing may be, as shown in the drawing,
or may be extended to the extreme end of the casing, and is made somewhat
narrower than the orifice in the casing which they cover so that when they are
closed a small slit is left through which the device to be exhibited can freely pass.
In the casing B are arranged the rollers K which are adapted to be revolved in the
casing by means of the knot or handle M. The rollers K are provided along the
greater part of their length with the slot N in which the rod O, which carries
the map or device P to be exhibited, is adapted to be secured.
Figs. 6. 7. 8 and 9 show various ways in which this may be effected. In Fig. 6
when the roller is made of wood or such like substance, two plates QQ¹ are
attached one over each end of the slot N, the plate Q covers twice as much of the
slot as the plate Q'.

page_text: One end of the rod O is passed under the plate, Q when it reaches the end of
the slot, the opposite end of the rod will be able to pass in front of the plate Q¹
when it can be slid back under the latter, until it touches this end of the slot
when the rod will be in the position shown in Fig. 6.
When the rollers are made of metal the plates QQ' will be dispensed with the
necessary recesses being formed in the material of the roller. In Fig. 7 a sliding
bracelet or sleeve R is used in place of the plate Q'. In Fig. 8 a catch S is adapted
to turn about a pin and cover or uncover the end of the slot N. In Fig. 9 a sliding
ring T of metal, indiarubber, or other suitable material is used for the same
purpose. The springs T hold the rod firmly in the slot and prevent it from shifting.
With this apparatus all devices such as letters of the alphabet, words, object lessons,
maps, and the like, whatever their relative sizes, can all be shown singly by one
apparatus, the size of the object being only limited by the length of the rollers,
and of the slotted bars of the frame. Any lesson can be easily and rapidly fixed to
or removed from the rollers. Though in the drawing the rollers are shown of the
same breadth as the frame A yet it is obvious that much longer rollers and casings
can be used, the holding pins being fixed at the requisite places on the roller, or,
when clips are used, on the bar joining the two clips.
When the objects of the lesson are of small size and the rollers therefore com.
paratively close together, the apparatus is preferably arranged so that the rollers
hang horizontally when however large maps diagrams or other objects are being
shown, and the rollers are therefore far apart, it is better to arrange the rollers
vertically so that the knobs are brought more conveniently within reach of the
operator.
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 device for attaching to a roller and detaching therefrom the material to
be wound on the roller, said device consisting of a rod to which the material to be
wound is attached, and a longitudinal groove in the roller for receiving the said
rod and in which the said rod is adapted to be secured substantially as described
and illustrated in the accompanying drawing.
2. For exhibiting maps, object lessons, and the like, the apparatus consisting of
the frame A provided with the slots C and a pair of casings B adapted to be
supported by the said frame and containing rollers on which the devices to be
exhibited are attached and wound substantially as described and illustrated.
