AN IMPROVED STILE OR BIPED PASS FOR PARKS OR OTHER ENCLOSURES
Year: 1869

page_text: LETTERS PATENT to John Gregory McKirdy, of Birkwood, Les-
mahagow, in the County of Lanark, North Britain, for the
Invention of "AN IMPROVED STILE OR BIPED PASS FOR PARKS OR OTHER
ENCLOSURES."
Sealed the 10th August 1869, and dated the 7th June 1869.
PROVISIONAL SPECIFICATION left by the said John Gregory M.Kirdy
at the Office of the Commissioners of Patents, with his Petition, on
the 7th June 1869.
I, JOHN GREGORY MCKIRDY, of Birkwood, Lesmahagow, in the
County of Lanark, North Britain, do hereby declare the nature of the
said Invention for "AN IMPROVED STILE OR BIPED PASS FOR PARKS OR OTHER
ENCLOSURES," to be as follows, that is to say:-
This Invention has for its object to provide for the entrance or exit of
men or women into or from parks or other enclosures by a simple con-

page_text: formation of parts, which without movable or adjustable elements will
obstruct the passage of lambs or other quadrupeds of the same or larger
size. The improved stile may also be combined with a gate or gates
to be fully opened when required for the passage of sheep or other
quadrupeds.
The Invention consists in shaping the sides of the stile or biped pass
*so that an adult can just pass through with one foot in advance of the
other; the opening or entrance being extremely narrow at the bottom
or ground level, and its width gradually increasing upwards and more
rapidly at the top. The precise dimensions may be varied, but about the
following widths of opening will be found convenient and suitable for a
fence three feet six inches in height. The first of these widths is at the
bottom, and the others are at intervals of six inches, four and three-
eighth inches, four and three-quarter inches, five inches, five and three-
eighth inches, five and three-quarter inches, seven and one-half inches,
twelve and one-half inches, and nineteen and three-quarter inches.
The opening is by preference made symmetrical, and the main side posts
may be bent or shaped to correspond with the dimensions given, or
vertical side posts may be used with rods or bars bent to the required
form, and fixed into the side posts at their upper ends, and into the
ground at their bottom ends, or the bottom ends may be connected by a
cross bar or base. The stile may be made in any convenient material,
such as iron, wood; stone, or brick. In strained wire fencing the side
posts of the stile may have the usual appliances for straining adapted
to them, so as to answer as straining standards also. Where an increased
opening for the passage of sheep or other quadrupeds is occasionally
required in the same place, one of the sides of the stile may be formed
upon or may constitute the outer or swinging end of a gate, such gate
being secured in its closed position by a vertical bolt at the outer
bottom corner. Or a pair of gates for a wide opening may have their
free ends shaped so as when closed to leave a narrow middle opening of
the conformation of the improved stile or biped pass.

filed by the said John Gregory M.Kirdy in the Great Seal Patent
Office on the 6th December 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN:
GREGORY MCKIRDY, of Birkwood, Lesmahagow, in the County of Lanark,.
North Britain, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of June, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Gregory M Kirdy, Her special licence-
that I, the said John Gregory McKirdy, my executors, administrators, and!
assigns, or such others as I, the said John Gregory McKirdy, my execu-
tors, 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 STILE
OR BIPED PASS FOR PARKS OR OTHER ENCLOSURES," upon the condition
(amongst others) that I, the said John Gregory McKirdy, 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 John Gregory McKirdy, 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 in writing, reference being had to the
accompanying Drawing, that is to say :-
My said Invention has for its object to provide for the entrance or
exit of men or women into or from parks or other enclosures by a
simple conformation of parts, which without movable or adjustable
elements will obstruct the passage of lambs or other quadrupeds of the
same or larger size. My improved stile or biped pass may also be

page_text: combined with a gate or gates to be fully opened when required for the
passage of sheep or other quadrupeds.
And in order that my said Invention, and the manner of performing
the same may be properly understood, I have hereunto appended an
explanatory Drawing, to be herein-after referred to, and representing a t
convenient modification of my improved stile or biped pass.
The Drawing is an elevation of the stile as inserted in a length of iron
standard and wire fencing.
My Invention consists in shaping an opening A, B, C, in the manner
shown, so that an adult can just pass through with one foot in advance
of the other; the opening being extremely narrow at the bottom or ground
level C, and its width gradually increasing upwards, and more rapidly
at and near the top A, B. The precise dimensions may be varied, but
the form shown in the Drawing will be found convenient and suitable
for a fence of the ordinary size. The opening A, B, C, is by preference
made symmetrical, and the main side posts may be hent to the shape,
or vertical side posts D, E, may be used as shown in the Drawing, with
rods or bars F, G, bent to the required form and fixed to the side
posts D, E, at their upper ends, and at their bottom ends to a cross bar
or base piece H. Bars I, J, may be arranged as shown to divide the
spaces between the posts D, E, and the inner bars F, G.
My improved stile or pass may be made in any convenient material,
such as iron, wood, stone, or brick. My Invention consisting in making
the sides of the opening of the shape shown, not in constructing the
parts of any particular material, nor in 'uniting them in any particular
way. Where an increased opening for the passage of sheep or other
quadrupeds is occasionally required in the same place one of the sides of
the stile F, for example, may be formed upon or may constitute the outer
or swinging end of a single gate, such gate being secured in its closed
position by a vertical bolt at the outer bottom corner. Or a pair of
gates for a wide opening may have their free ends shaped so as when
closed to leave a narrow middle opening of the conformation of my
improved stile or biped pass.
Having thus particularly described my said Invention, and the manner
in which the same is to be performed, I have to state that what I
*believe to be novel and original, and claim as the Invention secured to
me by the herein-before in part recited Letters Patent is, the shaping of

page_text: an opening, as herein described and delineated, to form a stile or biped
pass for parks or other enclosures.
In witness whereof, I, the said John Gregory McKirdy have
hereunto set my hand and seal, this Third day of December,
in the year of our Lord One thousand eight hundred and sixty-
nine.
J. GREGORY MCKIRDY. (L.S.)
