Year: 1864

page_text: LETTERS PATENT to Nicholas Jacques Peton, of No. 10, Rue de la
Fidélité, Paris, in the Empire of France, Gentleman, for the Invention
of "AN IMPROVED MACHINE FOR SWEEPING CHIMNEYS."
Sealed the 17th February 1865, and dated the 25th August 1864.
PROVISIONAL SPECIFICATION left by the said Nicholas Jacques Pecon
at the Office of the Commissioners of Patents, with his Petition, on the
25th August 1864.
I, NICHOLAS JACQUES PETON, of 10, Rue de la Fidélité, Paris, in the
Empire of France, Gentleman, do hereby declare the nature of the said
Invention for "AN IMPROVED MACHINE FOR SWEEPING CHIMNEYS," to be as
follows, that is to say :-
The Invention consists in an improved construction of machine for sweeping
chimneys. The machine consists partly of a box of an oblong form, in which
are introduced racks; at one of the upper extremities of the box is a small
hole through which the racks pass; the upper part of the first rack has a
screw, to which is fixed the apparatus for sweeping the chimney. This appa-
ratus consists of a hollow cast-iron block of a conical form, in which are
placed a number of steel blades, the extremities of which act as scrapers,
being made of thin steel, having the form of a comb, and of sufficient length
to scrape the internal sides of a chimney of any size. The conical opening
in the cast-iron block is closed by another block of a proportional size, and
having a flat surface, and on this surface are placed in a horizontal position

page_text: other blades similar to the first, and which fill the interstices between the
first blades; several horizontal rows of these blades are superposed, each row
is separated by a roller, the whole being secured by a screw bolt. Close to
the small opening in the box is a spring pressing on a pin, which enters the
small opening, and striking against a steel grooved piece connected with the
racks causes the said grooved piece to be raised or lowered when it is
required to unite or disunite the racks. This grooved piece is fixed at the
lower extremity by a small steel band acting as a spring, and which in
descending covers the upper part of the rack, and by this means unites two
racks. The same motion couples all the racks together. The rack is jointed
in the middle by a hinge to enable it to pass over all the curves. A moveable
projecting roller is placed on the hinge to prevent it coming in contact with the
uneven parts of the chimney and obstruct its ascension. A second hinge is
set at the top part of the racks to assist their ascent, which is effected by
means of a pinion and cog wheel put in motion by a crank arm at the other
extremity of the box. Connected with the crank arm is a bevil wheel which
transmits its motion to another pinion, which causes a screw to turn and the
nut to advance the length of the box; when the motion of the crank arm is
transmitted to the screw, the nut of the latter pushes forward a spring which
presses on the racks, contained in the box, and causes them to advance so
soon as the rack in rising leaves the box and enters the chimney. The
pressure of the spring causes the head of each of the racks to advance and
follow the one that preceeds it. On the shaft of the machine is a ratchet
and on the box a pawl, serving to stop the descending action of the racks.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Nicholas Jacques Peton in the Great Seal Patent Office on
the 25th February 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NICHOLAS
JACQUES PETON, of .No. 10, Rue de la Fidélité, Paris, in the Empire of
France, Gentleman, send greeting.
. WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of August, in the year of our-Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Nicholas Jacques Peton, Her special licence that I, the said Nicholas
Jacques Peton, my executors, administrators, and assigns, or such others as.

page_text: I, the said Nicholas Jacques Peton, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter 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 "AN IMPROVED MACHINE FOR SWEEPING CHIMNEYS," upon the condition
(amongst others) that I, the said Nicholas Jacques Peton, 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 Nicholas Jacques Peton, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, reference being had, to the. Drawing hereto annexed, and
to the figures and letters marked thereon, that is to say :-
My Invention has for object the construction of an apparatus for sweeping
chimneys, which consists of a certain number of racks adapted one to the
other, according to the elevation of the chimney to be swept. The upper-
extremity of the first rack is provided with a screw to which the 'sweeping
apparatus is fitted, which is composed of a number of rows of scrapers made
of steel, and having the form of a comb of a sufficient length to scrape the
internal sides of any chimney.
In order to render my Invention better understood, I will now refer to the
Sheet of Drawings hereunto annexed, and to the letters marked on the several
Figures therein contained.
.
In Figures 1 and 2, a is a box of an oblong form, in which are introduced.
racks A; at one of the upper extremities of the box is a small hole B, through
which the racks pass; the upper part of the first rack has a screw, to which is
fixed the apparatus A', for sweeping the chimney.. This apparatus consists of
a hollow cast-iron, block of a conical form, in which are placed a number of
steel blades, the extremities of which act as scrapers, being made of thin' steel,
having the form of a comb, and of sufficient length to scrape the internal sides
of a chimney of any size:: The conical opening in the cast-iron block is closed
by another block of a proportional size, and having a flat surface. On this.
surface are placed in a horizontal position other blades similar to the first, and
which fill the interstices between the first blades; several horizontal rows of

page_text: these blades are superposed, and each row is separated by a roller, and the
whole being secured by a screw bolt. Close to the small opening in the box-
is a spring pressing on a pin D, which enters the small opening, and striking
against a steel groove piece E connected with the racks causes the said
grooved piece E to be raised or lowered when it is required to unite or
disunite the racks. This grooved piece is fixed at the lower extremity by a
small steel band acting as a spring, and which in descending covers the upper
part of the rack, and by this means unites two racks. The same motion
couples all the racks together. The rack is joined in the middle by a hinge G
to enable it to pass over all the curves. A moveable projecting roller G¹ is
placed on the hinge G to prevent it coming in contact with the uneven parts
of the chimney and obstruct its ascension. A second hinge H is set at the
top part of the racks to assist their ascent, which is effected by means of a
pinion K and wheel N put in action by a crank arm P at the other extremity
of the box. Connected with the crank arm P is the pinion N in communi-
cation by the chain O with the pinion q, which moves a screw S of the same
length as the box. The movement of the crank arm is communicated to the
screw S, and this screw causes the spring U to advance, which pressing on
the racks contained in the box forces them to advance as soon as the rack in
rising-leaves the box and enters the chimney. The pressure of the spring U
causes the introduction of the upper part of each rack into the lower part of
the rack which precedes it. On the shaft e of the machine is a ratchet Land
a paul M, serving to stop the descending action. Instead of using the racks
herein-before described, they can be replaced. by an endless chain D, Figures
3, 4, 5, 6, passing on a cross piece B fixed permanently at the top of the
chimney. The cross piece B supports a pulley C. The bottom of the
chimney is provided with a pinion G set in movement by a crank arm J.
The said endless chain draws the sweeping apparatus B in a manner similar
to the comb employed in hand-sweeping apparatuses.
In Figures 1 and 2, a is a box containing a spring pushing the pin D;
T, head of the racks; I,' axis of the machine; J, journals of the axis; L, cog
wheel; V, crank arm causing the screw to return; ✗; cross pieces supporting
the racks; Y, small roller pushing the racks to disunite them when descending;
b, plate serving to guide the racks; c, spring; e, arbor; G, small roller pre-
venting the friction of the racks.
In Figures 3, 4, 5, and 6, E is the comb; H, the axis of the pinion;
I, journal; J, crank arm; K, frame.
And having now described my Invention, and the best mode of putting the
same into execution, I wish it to be understood that I do not restrict myself

page_text: to the precise details of construction herein-before stated, provided the
principle of my Invention be retained; but what I claim is, the combination
er arrangement of the several mechanical parts or appliances, or their equi-
valents, forming an improved chimney sweeping apparatus, substantially as
herein-before fully set forth and described, reference being had to the Figures
of the Drawing.
In witness whereof, I, the said Nicholas Jacques Peton, have hereunto
year
set my hand and seal, this Twenty-third day of February, in the
