Year: 1863

page_text: LETTERS PATENT to Frederick Tolhausen, of 17, Faubourg Montmarte,
Paris, Patent Agent, for the Invention of "IMPROVEMENTS IN MACHINES
FOR CARDING FIBROUS MATERIALS."-A communication from Henry
Bossbard, Mechanical Engineer, residing at the Number and Street
aforesaid.
Sealed the 6th April 1863, and dated the 24th January 1863.
PROVISIONAL SPECIFICATION left by the said Frederick Tolhausen at the
Office of the Commissioners of Patents, with his Petition, on the 24th
January 1863.
I, FREDERICK TOLHAUSEN, of 17, Faubourg Montmartre, Paris, Patent
Agent, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINES FOR CARDING FIBROUS MATERIALS," a communication from Henry
Bosshard, Mechanical Engineer, a person resident at the Number and Street
aforesaid, to be as follows:-
These improvements consist in applying doffing combs to each of the
rollers that in a certain description of carding engines are set around the
main carding cylinder; the object of this addition is either to obtain a greater
quantity of carded material, or to produce a finer lap of superior quality. In
the former case the webs produced by the rollers and their combs are at once
delivered or taken off, either laterally, or in any other direction by delivery
rollers; in the latter case the webs doffed by the said combs are united into

page_text: one lap, which is at once passed through the carding engine again. The said
combs are set in motion by means of any of the devices now in use for
doffing combs.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Frederick Tolhausen in the Great Seal Patent Office on
the 23rd July 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
TOLHAUSEN, of 17, Faubourg Montmartre, Paris, Patent Agent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of January, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign did, for Herself, Her heirs and successors, give and grant. unto me,
the said Frederick Tolhausen, Her special licence, that I, the said Frederick
Tolhausen, my executors, administrators, and assigns, or such others as I, the
said Frederick Tolhausen, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make, use;
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINES FOR CARDING FIBROUS MATERIALS," a communication from Henry
Bosshard, Mechanical Engineer, a person resident at the Number and Street
aforesaid, upon the condition (amongst others) that I, the said Frederick
Tolhausen, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Frederick Tolhausen, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
These improvements consist in applying doffing combs to each of the
rollers that in a certain description of carding engines are set around the
main carding cylinder; the object of this addition is either obtain a greater

page_text: quantity of carded material, or to produce a finer lap of superior quality. In
the former case the webs produced by the rollers and the combs are at once
delivered or taken off, either laterally, or in any other direction, by delivery
rollers; in the latter case the webs doffed by the said combs are united into
one lap, which is then at once passed through the carding engine again. The
said combs are set in motion by any of the devices now in use for: doffing
combs.
Having thus briefly described the nature of this Invention, I will now set
forth the manner in which the same is or may be carried into effect.
Fig. 1 is a side elevation of a carding engine baving four working rollers,
but the number of these rollers may be varied according to requirements.
A is the main cylinder or drum; B, the doffer; D, the feed rollers; E, the
doffer comb; c, f, g, h, working rollers, from which the combs i, k, m, detach
the web, in the manner shewn at Fig. 3, so that the fibre is carded in an
opposite direction to which it was before being detached. The webs may also
be united and carried to the feed rollers again, as shewn by a dotted line,
Fig. 1. The working combs are driven from any shaft of the engine by
means of straps, pulleys, cranks, and coupling rods, as fully shewn at Fig. 1.
In order to save room, the working combs may also be arranged near the top
of the rollers, as shewn at Fig. 2 in elevation, and Fig. 2* in plan.
In witness whereof, I, the said Frederick Tolhausen, have hereunto set
my
hand and seal, this Eighteenth day of July, A D. 1863.
F. TOLHAUSEN. (L.S.)
