Mechanician Jeweller, for the Invention of "STOPPING INSTANTANEOUSLY
TO DATE TO DOZIOM DATE ATT
Sealed the 25th July 1856, and dated the 28th January 1856.
PROVISIONAL SPECIFICATION left by the said Pierre Emmanuel Guérinot
at the Office of the Commissioners of Patents, with his Petition, on the
28th January 1856.
I, PIERRE EMMANUEL GUÉRINOT, of Ruc au Maire, in Paris, Mechanician
Jeweller, do hereby declare the nature of my Invention for STOPPING INSTAN
TANEOUSLY TWO RAILWAY TRAINS RUNNING AGAINST EACH OTHER," to be as
follows:-
The Invention consists in placing on the right side of the locomotive, and of
each waggon of the train, forwards and backwards in place of the buffer, or by
its side, a conical iron protecting rod terminated by a sharp steel point,
the base of the conical rod being about 3 to 5 inches in diameter, and its
length from 4 to 9 feet. The disposition of my Invention is represented in
the annexed Drawing, where two waggons of a same train, 1 and 2, Fig. 1, are
represented on the rails R, R. The protecting points P, P, are fixed to the
head cross pieces T, T, on the outside of which they rest on a shoulder, whilst
they are fastened inside by a screw nut. Opposite the points P, P, leaden
discs or blocks B, B, are fixed on the left side of the head pieces T. The said
leaden discs are inserted in iron rings, fixed by screws to the head pieces;
the discs B are about 6 or 8 inches in diameter, and from 3 to 6 inches in
thickness. When two trains are running against each other, the protecting.

way
If a faster train arrives behind a slower one the same effect is produced, the
protecting point of the locomotive forcing its way into the buffing block of the
last waggon, and at the same time the point of the waggon running into
the block of the locomotive. The same effect takes place between all the
waggons of the train. The buffing blocks, instead of being of pure lead, may
be made of any suitable compound of metals or of other suitable materials.
Fig. 2 is a protecting point represented alone and on a larger scale. Behind
the buffing bles B there is an empty space or box C, into which the point
passes freely after piercing through the leaden blocks.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Pierre Emmanuel Guérinot in the Great Seal Patent Office
on the 25th July 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PIERRE
EMMANUEL GUERINOT, of Rue au Maire, Paris, Mechanician Jeweller, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letter3
Patent, bearing date the Twenty-eight day of January, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Pierre Emmanuel Guérinot, Her special licence that I, the said Pierre
Emmanuel Guérinot, my executors, administrators, and assigns, or such others
as I, the said Pierre Emmanuel Guérinot, 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 Ircland, the Channel Islands, and Isle of Man, an Invention for
"STOPPING INSTANTANEOUSLY TWO RAILWAY TRAINS RUNNING AGAINST EACH OTHER;"
upon the condition (amongst others) that I, the said Pierre Emmanuel Guérinot,
my executors or administrators, by an instrument in writing under or their, or
one of their hands and seals, should particularly describe and acertain the
nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the said Letters
Patent.

page_text: NOW KNOW YE, that I, the said Pierre Emmanuel Guérinot, 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:-
My Invention consists in placing a sharp hardened pointed iron rod at the
right-side front part of each locomotive engine, such point being turned of. a
regular smooth, tapered, or conical shape, provided with a shoulder which bears
against the front cross piece of the engine, and on which cross piece it is.
fastened by a nut E, screwed tight on the axis of the point set in the cross piece
as seen (Figs.) 3 & 4 of the annexed Drawing. I place, likewise, such points
on all the wagons of each train, and on both sides; viz., at the fore and hind
cross piece, at the right hand; and at the left hand I place à lead block, so
that whichever way the wagons are turned, there is always a lead block of each
wagon opposed to the point of the adjoining one, and if perchance two trains
approach each other in opposite directions, there should be no clashing, because
the sharp points of the locomotive engines will run through the opposite lead
blocks of each other without serious concussion, through encountering a resis-
tance which will weaken or deaden the stroke, and stop instantaneously the
speed of each train, the engines of which will remain motionless without spring-
ing back as is the case with the buffers, whilst the points of the wagons running
on after the stopping of the engines, will also run through the opposite lead
block of each other, and remain motionless as their driving engines. Fig. 3
shews two wagons of a train placed on the rails; the protecting points P, P;
are fixed on the right side of the end cross pieces T, T. Opposite to the points
lead blocks B, B, are fixed on the left side of the said cross pieces, where they
are maintained by iron rings, or any other suitable contrivance, so as to allow
of removal when they have been run through by the points... The lead blocks
may be from about 6 to 10 inches in diameter, and from 4 to 12 inches thick;
an empty space V is behind the lead block to allow the free passage of the
points, which are from 3 to 6 inches in diameter, and from 4 to 9 feet long.
Fig. 1 is a side view, and Fig. 2 a plan of two locomotive engines, running
against each other, and at the very moment they are encountering; in this
case the protecting points P are represented of a reverted system; viz., the
points P, P, of the protecting rods are not turned outside the engine, as in
Fig. 3, but they are turned inwardly, and the lead blocks B, B, are placed
inside the engine, about the middle part, as seen in Fig. 2; behind the lead
block there is a stout piece of cast iron screwed tight on the framework, and is
pierced with a hole opposite to the point P, in order to let it pass freely when
the lead has been' penetrated.

page_text: In order to render more efficient my protecting points, I may place two
instead of a single point in front of each locomotive engine, as seen in Fig. 2;
the first point P being placed on the right side inwardly, where the parts of the
engine will allow of placing it; the second one, P₁, I place outside the frame,
both sliding in suitable cast-iron guides A, A¹. The side of the protecting rods
opposite to the point is shaped as a head or buffer which is struck by the
head cross piece T of the opposite locomotive engine. In order to have a
more progressive and efficient stopping effect, I have the protecting points
P and P¹ of a different length; the latter being longer produces first its effect,
as seen in Fig. 2, where it is just touching the head cross piece, whilst the
point P is yet a little apart, and will bear successively when the point P¹ is
already in the lead. I make the protecting points in the case of Figs. 1 & 2
about the same length as the engine, although the length and arrangement may
be modified according to requirements. My Invention being now described, I
declare that I do not confine myself to the precise shape, disposition, and arrange-
ment of the pieces, such as they are described and represented on the annexed
Drawing; but what I claim more particularly is, applying pointed iron rods,
placed on one side of the head cross piece of locomotive engines and wagons,
and blocks either of lead or any other similar soft material or composition
placed on the other side, so as to have the point of one vehicle to meet the
block of the other, in order to weaken or deaden the concussion of such
vehicles, and to stop almost instantaneously railway trains running against
each other. I claim also, applying such protecting rods or points either by
fastening at the head cross piece of wagons or engines,. the point being
outwards, as in Fig. 3 of the annexed Drawing, or being made to slide freely
in guides, the point turned inwards and the opposite side being head shaped;
as in Figs. 1 & 2. Also, I claim applying one or several points of different
lengths to each vehicle as seen in Fig. 2, so as to operate successively.
In witness whereof, I, the said Pierre Emmanuel Guerinot, have here-
unto set my hand and seal, this Twenty-third day of July, in the year
of our Lord One thousand eight hundred & fifty-six, (this 23rd day
