IMPROVEMENTS IN. THE CONSTRUCTION OF MACHINERY OR APPARATUS FOR SHAKING CARPETS
Year: 1880

page_text: LETTERS PATENT to Hugh Aspin, of Manchester, in the County of Lancaster,
for an Invention of "IMPROVEMENTS IN. THE CONSTRUCTION OF MACHINERY OR
APPARATUS FOR SHAKING CARPETS."
PROVISIONAL SPECIFICATION left by the said Hugh Aspin at the Office
of the Commissioners of Patents on the 7th May 1880.
"IMPROVEMENTS IN
HUGH ASPIN, of Manchester, in the County of Lancaster.
THE CONSTRUCTION OF MACHINERY OR APPARATUS FOR SHAKING CARPETS."
The object of this Invention is to construct a machine to perform the laborious
operation of shaking the dust out of carpets, the machine being so arranged as to
shake any ordinary size of carpet.
It consists principally of a frame in which the carpet is secured by means of
rails and clamps, so that it is firmly held at the edges (and at the centre also if a
wide carpet) and hangs loosely in a bag like form between the rails.
This frame is mounted so as to be capable of rising and falling in slots in a
convenient number of vertical posts or pillars, and the frame is slung by means of
connecting rods from the cranks of two crank shafts above. A rapid rotary
motion is imparted (by hand or otherwise) to one of these crank shafts, and the
two being so connected together by rods or by chains passing round stud pulleys
or otherwise that they revolve simultaneously in the same direction.
A rapid
rising and falling motion will be given to the frame, and as the carpet hangs
loosely (or bags) between the rails a rapid jerking motion given thereto, which
will have the effect of shaking the dust out of the carpet.
In some cases I enclose the frame and carpet in a casing, and by means of a fan
I draw away the dust and blow it into a suitable receptacle, where it can be damped
by means of a jet of steam or water.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Hugh Aspin in the Great Seal Patent Office on the 5th November
1880.

" IMPROVEMENTS IN
THE CONSTRUCTION OF MACHINERY OR APPARATUS FOR SHAKING CARPETS."
The object of this Invention is to construct a machine to perform the laborious
operation of shaking the dust out of carpets, the machine being so arranged as to
shake any ordinary size of carpet.

page_text: The construction and working of the machine will be readily understood from
the following description thereof, and on reference to the Sheet of Drawings
hiereunto annexed, in which Fig. 1 is a vertical cross section of the apparatus, and
Fig. 2 is a partial elevation of the driving end thereof.
The apparatus consists principally of a frame a, a, in which the edge of the
carpet is secured by means of rails b, b, and clamps c, c, so that it is firmly held at
the edges, and at the centre also if a wide carpet, and hangs loosely in a bag like
form between the rails, as shown by. the dotted lines in Fig. 1, the centre part of
the carpet being held by a strap or bar d, d, which is secured by a clamp at each
end.
This frame a, a, is mounted so as to be capable of rising and falling in slots in
a convenient number of vertical posts or pillars e, e, or it is guided by means of
rollers, working against the posts e, e, and the frame a, a, is slung by means of
connecting rods g, g, from the cranks.h, h, of two crank shafts i, i, above.
A rapid rotary motion is imparted (by means of gearing h, k, or otherwise) to
one of these crank shafts, and the two being so connected together by the gearing,
or by rods, or by chains passing round stud pulleys or otherwise, that they revolve
simultaneously in the same direction (or in opposite directions). A rapid rising
and falling motion will be given to the frame a, a, and as the carpet hangs loosely
(or bags) between the rails of the frame a rapid jerking motion is given thereto,
which will have the effect of shaking the dust out of the carpet.
Beneath the frame a, a, I prefer to place a grid or grating 1, 1, made of laths of
wood or other suitable material, against which the under side of the carpet strikes
as the frame descends, and which assists in driving the dust out. The central
portions *, *, of this grating are removable so as to adjust the same to various
widths of carpet, and for the same purpose the outer side rails a*, a*, of the frame
are capable of adjustment, the ends of the said rails not being attached to the
transverse rails, but connected thereto by means of a wrought iron strap, as shown
at m, m, in Fig. 2, the said strap being capable of sliding on the transverse
rails a, a, which are provided with holes (as at o, o,) and a movable pin p, p, to fix
them when adjusted.
In some cases I enclose the frame and carpet in a casing, and by means of a fan
I draw away the dust and blow it into a suitable receptacle, where it can be damped
by means of a jet of steam or water.
Having now described the nature and object of my said Invention together with
the manner in which the same is to be or may be performed or carried into
practical effect, I wish it to be understood that I claim as my Invention the
machine or apparatus for shaking carpets, constructed as herein before described
and illustrated by the Drawings annexed, or any mere modification or imitation
thereof constructed and operating in substantially the same or a similar manner.
In witness whereof, I, the said Hugh Aspin, have hereunto set my hand and
seal, this Fourth day of November, in the year of our Lord One thousand
eight hundred and eighty.
HUGH ASPIN. (L.S.)
