page_text: WHEREAS I am in possession of an Invention for "CERTAIN IMPROVE-
MENTS IN CANOPIES," a communication to me from Augusta Margarette
Rodgers, a person resident at Brooklyn, New York, United States of
America, and have petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns Her Royal Letters Patent for the
same, and made solemn Declaration that it is a communication.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the Invention, and the
manner in which the same is to be performed, reference being had to
the accompanying Drawings, and to the figures and letters marked
thereon, that is to say :-
.
This Invention, communicated to me, consists in a novel construction
of the frame of a canopy and in a novel arrangement of lifting cords
and their appurtenances for raising the net of the canopy, whereby a
neat and desirable apparatus is produced susceptible of being secured to
the ceiling over a bed or other desirable locality in an apartment, the
curtains or skirt of the net thereof being so arranged that the same,
when not in immediate use, may be easily drawn up out of the way,
while both the net and the frame are capable of being readily taken
apart when the season for its use is past, and when taken apart of being
packed in a trunk or other small receptacle, for convenience of storage
or transportation, and afterwards put together with equal facility when
their service is again required. The disk to which the arms of the
frame are secured, is provided with a series of guiding loops, rings, or
equivalent devices, so that the cords which lift the net will be untied
at one point and drawn simultaneously. With the frame of the canopy
is combined a disk capable of being permanently secured to the ceiling.
This Invention is illustrated in the accompanying Drawing, in which
Fig. 1 represents a side view of the canopy when the same is in its
working position; Figure 2 is a transverse section of the same, the
line x, x, Figure 3, indicating the plane of section; Figure 3 is an
inverted plan of the frame supporting the network of the canopy;
Figures 4 and 5 are details which will be referred to as the description
progresses. Similar letters indicate corresponding parts.
'
In the Drawing the letter A designates a disk. having a suitable
number of holes a in. its periphery and an equal number of guide rings
or loops 6 screwed into or otherwise suitably attached to its lower

page_text: surface, in position corresponding to the holes a.
Radial arms B are
fitted to enter the holes a and are provided at or near their outer ends
with buttons f, from which the net c is suspended. These buttons are
used in preference to mere hooks, because they are less liable to tear the
net and they impart to the whole device, a neat appearance. In the
under sides of the radial arms are also secured guide rings or loops c,
and the net is provided with perpendicular rows of guide rings or loops d
corresponding in position to the loops c. To the bottom edge of the net-
work are attached lifting cords e, one under each row of guide rings d,
and these cords are passed through said guide rings and through the
loops c, b, their inner ends being thus carried near to the centre of the
disk A, under which they are united by a tassel D or any other
ornamental pendant. By pulling on this tassel the net is raised, and if
the tassel is then fastened to a bed post or some other fixture provided
for that purpose the net is retained in an elevated position. To ensure
the ready dropping of the net, weights E are attached to its bottom at
each lifting cord. Through the centre of the disk A passes a thumb
screw G, which screws into a secondary disk F, and this latter disk is
intended to be permanently secured to the ceiling by means of screws h.
By means of the thumb screw G therefore the canopy can be readily
fastened in position or unfastened when the same is not to be used.
When it is desired to put the canopy away the net is unfastened from
the arms B, said arms are drawn out of the disk A, and the whole device
can be stored away in a small compass.
In some cases it may be desirable to raise and lower the canopy by
means of a cord and pulley, and in these cases the secondary disk F and
the thumb screw G can be dispensed with.
The arms B may also be fastened to the disk A by screws or other
means, so as to form a frame capable of supporting the net and of being
readily taken apart.
Having thus described the said Invention, and the manner of per-
forming the same, I will add that what I claim and desire to secure by
the said Letters Patent is,-
-
1st. The arms B radiating from a common centre and capable of being
detached therefrom, said arms being provided with buttons for the
support of the net and with loops for the lifting cord, substantially as
described.

page_text: 2nd. The disk A provided with a series of guides b, so arranged as to
unite the lifting cords centrally at one point, substantially as set forth.
3rd. In combination with said disk A the secondary disk F applied
and operating as described.
4th. The disk A with radiating holes a, the guides b, arms B,
buttons f, screw G, lifting cord e, and net C, combined and operating
together substantially in the manner herein shown and described.
In witness whereof, I, the said Henri Adrien Bonneville, have
hereto set my hand and seal, this Twenty-second day of July, in
the year of our Lord One thousand eight hundred and seventy.
