"
at the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 2nd January 1871, pursuant to the 9th Section

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex,
Patent Agent, send greeting.
WHEREAS I am in possession of an Invention for "A NEW AND IM-
PROVED CARPET BEATER," and have petitioned Her Majesty to grant unto
me, my executors, administrators, and assigns, Her Royal Letters Patent

page_text: for the same, and have made solemn Declaration that it has been com-
municated to me from abroad by William Henry Hankinson, of the City,
County, and State of New York, United States of America.
NOW KNOW YE, that I, the said Alexander Melville Clark, do hereby
declare that the following Complete Specification, under my hand and 5
seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed in and by the following
statement, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say) :
This Invention relates to a new machine for beating and cleaning 1
carpets and other fabrics, and consists in a new mechanism for operating
elastic wire beaters or whips, and more particularly in a new arrange-
ment of double-acting springs by which the strokes of the beaters are
made elastic and properly yielding. The carpet is thereby prevented
from injury during the heating process
1

page_text: springs h, h, connected with a cross bar i of the frame A. When the
shafts B, C, are swung by means of the pins d the springs h are
stretched, and will, as soon as the pins d leave the cranks c, rapidly
contract so as to swing the shafts back and powerfully force the beaters
against the carpet suspended between them. Thus as the shafts F are
being revolved the beaters will be alternately carried away from and
against the carpet, and will consequently beat the same in the requisite
manner. j, j, are compensating springs, weaker than the springs h, and
applied to the opposite sides of the cranks g, as shown; they serve to
temper the strokes of the beaters, tending to draw them off the carpet
at the moment of the stroke, and prevent thereby the injuring of the
carpet by the violence of the strokes. F, F, are rotary brushes arranged
above or below the beaters on opposite sides of the carpet, and connected
with the driving shaft by suitable devices; they serve to remove the
dust laid loose by the beaters. The carpet is hung upon suitable
rollers G, H, which are revolved to gradually move it along between
the beaters. It is evident that the springs used in connection with the
rock shafts B, C, may be made spiral, flat, or of other suitable form, of
metal, rubber, or other material. A case I may be used to envelope
the beating and brushing machinery, and to keep the dust from flying
about.
Having described the nature of the Invention, and the manner of
performing the same, I declare that what I claim as the Invention to
be protected by the herein-before in part recited Letters Patent is,―
1st. The beaters D, D, secured to rock shafts B, C, on opposite sides
of the carpet, so as to strike the same as it passes between the beaters,
substantially as herein shown and described.
2ndly. The shafts B, C, provided with cranks c and combined with
the pins d on the disc e, to be operated substantially as herein shown
and described.
3rdly. The springs h combined with the 'compensating springs j for
the purpose. of actuating the carpet beaters, substantially in the manner
hercin shown and described.
4thly. The pins & made adjustable on the discs e for the purpose of
regulating the stroke of the beaters, substantially as herein shown and
described.

page_text: 5thly. The carpet beaters D, D, arranged substantially as described in
combination with the brushes F, F.
In witness whereof, I, the said Alexander Melville Clark, have
hereunto set my hand and seal, this Second day of January, in
the year of our Lord One thousand eight hundred and seventy-
one.
Witness,
Wч. CLARK,
