Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
DARNELL, of Belmont, Ramsgate, in the County of Kent, Gentleman, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the First day of May, in the eighth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said James
Darnell, my exors, admors, and assigns, Her especial licence, full power, sole
privilege and authority, that I, the said James Darnell, my exors, adñiors, and
assigns, or such others as I, the said James Darnell, my exors, admors, or
assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN MACHINERY FOR
BEATING AND BRUSHING CARPETS;" in which said Letters Patent is contained
a proviso that I, the said James Darnell, shall cause a particular description of
the nature of my said Invention, and in what manner the same is to be per-
formed, to be inrolled in Her said Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said in
part recited Letters Patent, as in and by the same, reference being thereunto
had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Darnell, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawings hereunto annexed, and to the figures and letters marked
thereon, that is to say:―
My Invention consists of combining a series of beaters into a machine for
beating carpets, and also of applying a rotatory brush, with suitable machinery,
for brushing carpets. And in order that the Invention may be most fully
understood and readily carried into effect, I will proceed to describe the
Drawings hereunto annexed, in the various Figures of which the same letters
of reference are used to indicate similar parts.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a left-band end view of a machine, the parts of which are
constructed and combined according to my Invention. Figure 2 shews a
sectional view, and Figure 3 shews a front view of the machinery. a, a, is
the framing of the machine, the nature of which is clearly shewn in the
Drawings. b, b, are a series of beaters: mounted on springs, and they are so
arranged that having been drawn or moved back, they, by the aid of springs,
each gives a sharp blow to the carpet placed opposite to them. The beaters 6
are mounted on a spring c, and in addition to such spring, each beater is further
aided by a coiled, spring d on the rod e. The rods e are.attached by means of
pin joints, to, the beaters. 6, and the other ends of the rods e pass through the
fixed barf, and they move through. holes, formed. in, such bar; and to prevent
the rods being forced too far by their springs a nut is screwed on, to the end; of
each of the rods e.. On each of the rods, e is formed a projection e, against
which projections e¹ the wipers g, affixed on the roller. h, come and move back
the rods; e, and consequently the beaters and the wipers g having passed beyond
the projections e¹ the beaters spring towards. and strike the carpet each with
a sharp blow.
Motion is communicated, to the roller h in, the following
manner is a cranked axis moving in. bearings at i,, and on the end of
this axis is placed the cog wheel j, which takes into and drives the wheel. k.
which is an intermediate wheel, and it takes into and drives the cog wheel l
affixed, on the axis of the. roller h.. The machinery, above, mentioned may be
put into and out of gear with the cranked; axis. by means of a clutch box m
by which the cog wheel j may be retained to the, axis and, turn, therewith or
be released therefrom,, so that, the axis: may be, turned: without putting the
beaters into motion. In each of the rods e there is a hole formed, to receive
a pin which retains, the same when. desired out of action, as is, shown by red
lines in Figure 2. On the other, or left-hand end of the cranked axis, i
cog

page_text: placed a pulley or drum with a clutch box and lever n, to put the same into
and out of gear with the axis. The drum or pulley by an endless band give
motion to the drum or pulley o, affixed on the axis p; this axis carries a series
of rotatory brushes q, q, which I prefer to have with brushes only in two rows
on opposite sides, as is shown in the Drawings. By this brush a carpet may
be quickly brushed as the carpet is made to move past the revolving brushes,
so that it will be seen that the machine is suitably arranged to act as a
beating machine and as a brushing machine for cleaning carpets. The ma-
chinery is mounted on wheels r, r, and r; 1, the wheels r', r, being guided
by moving on a rails, by which the machine can be made to move to and fro,
so as to change its position, and thus allow of the beaters acting on different
parts of the carpet, which is held in a position to be beaten.. And in order to
move the machinery to and fro there is a connecting rod v attached by a pin
joint to a crank pin w, affixed to a disc on the nave of the intermediate wheel,
and this connecting rod at its lower end is attached by a pin joint to the sector
plate a, to which is attached a driver a¹ by a pin joint, as is shown, and such
driver moves constantly to and fro by the movement of the sector plate, and is
the means of moving the, machinery to and fro. The driver when moving in
one direction takes into a tooth of the ratchet wheel y on the axis of the
wheels r, r, at the right-hand end of the machine, so as to move the ratchet
wheel, and consequently the axis, round; and as the wheel r is fixed on its axis
the machine will be moved in one direction, and it would continue to move in
one direction at all times but that the driver is capable of being moved from
the wheel y to the ratchet wheel y', the teeth of which are formed in an oppo-
site direction to those of the wheel y; consequently when the driver is moving
in the opposite direction to that in which it drives the wheel y it will give
motion to. the wheel y', affixed on the same axis as the wheel y, which will
cause the machine to be moved back, and the driver a¹ is caused to act on the
wheel y or the wheel y¹ according to the will of the workman, there being
an axis z, on which is fixed a wheel 21, which is rough on its periphery, so that
the workman by his foot may turn it. On the axis z is formed two guiding
surfaces (1) and (2), and according as the guiding surface (1) or (2) is
uppermost, and has for the time being the stem of the driver within it, so will
it be the wheel y or y' which will be put in motion by the driver. The
guiding surfaces (1), (2), are notches or grooves cut on opposite sides of a
cylinder, and there is an inclined plane formed opposite to each notch or
groove, so that supposing the stem of the driver to have been working or
sliding to. and fro in the groove (1), and the axis were to be turned half

page_text: round, the stem of the driver would pass out of the groove (1) and come
upon the inclined plane on the opposite side of the cylinder, and the weight of
the driver would cause it to descend down such inclined plane into the groove
or notch (2), and there it would continue to work till the axis was again
turned so as to bring it again into the notch or groove (1); and in case it be
desired to prevent the machine moving to and fro, then the axis z would only
be turned one quarter round, so that the cylinder not being cut away at those
sides, the stem of the driver would be upheld so as to be out of action. The
carpet to be beaten and brushed is placed on a roller A, which is turned by
means of bars or arms B, B, so as to move the carpet up or down to be
beaten or brushed, there being cords B¹ affixed to each of the arms B, as shewn,
by which those arms, and consequently the roller A, may be turned on the
axis A', and the roller A may be prevented turning by affixing the ends of
two of the cords B¹ to a pin on the framing, as shewn, and there are short
pins or studs on the surface of the roller I to prevent the carpet slipping
while it is being beaten. C, C, are cords fixed across the framing to support
the carpet and to hold it against the blows of the beaters.
In the above description, and in the Drawings to which such description
applies, I have shown the beaters to be mounted on springs, but in place
thereof I can use beaters mounted as levers on axes, and aided by springs, to
cause them each to give a sudden blow when released; and in order that this
may be understood, I have at Figure 4 shown a right-hand end view in section
of a machine, with beaters 6 so mounted, in which bis the beater, b' the
shorter end of the lever which is acted on by the spring 6%. The wipers (on the
roller, which in this case is placed lower down in the machine,) give motion to
the lever beaters b, and as they are released by the wipers the springs react
and cause the beaters to give the carpet a succession of short blows. Motion
is communicated to the wiper roller from the cranked axis through an inter-
mediate wheel, as before described, and as is clearly shewn in this Figure.
I have not thought it necessary to show a complete machine with lever beaters
as the parts not shown in this Figure would be similar to those above
.described.
Having thus described the nature of my Invention, and the best means
I am acquainted with for performing the same, I would wish it to be under-
stood that I do not claim any of the parts separately, nor do I confine myself
to the precise arrangement of apparatus or machinery which is shown for
giving motion to a series of beaters and of brushes, so long as the peculiar
character of my Invention be retained; but what I claim is, the combining

page_text: series of beaters into a machine for beating carpets, and applying rotatory
rushes combined with suitable machinery for brushing carpets.
In witness whereof, I, the said James Darnell, have hereunto set my hand
and seal, this Thirty-first day of October, in the year of our Lord
One thousand eight hundred and forty-five.
AND BE IT REMEMBERED, that on the Thirty-first day of October,

our said Lady the Queen in Her Chancery, and acknowledged the Specifi-
cation aforesaid, and all and every thing therein contained and specified, in
form above written. And also the Specification aforesaid was stamped
according to the tenor of the Statute made for that purpose.
