Year: 1814

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
MABERLY, of Welbeck Street, Cavendish Square, in the County of Middlesex,
Coach Maker, and JOHN BARROW, of York Court, East Street, Mary-le-bone,
in the said County, Smith, send greeting.
WHEREAS His most Excellent Majesty King George the Third did,
by His Letters Patent under the Great Seal of the United Kingdom of
Great Britain and Ireland, bearing date at Westminster, the Twenty-fifth
day of June, in the fifty-fourth year of His reign, give and grant unto us,
the said John Maberly and John Barrow, our exors, aduiors, and assigns,
His especial licence, full power, sole privilege and authority, that we, the
said John Maberly and John Barrow, our exors, admors, and assigns, during
the term of years therein mentioned, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, our Invention of "A METHOD OF SECURING CARRIAGE GLASSES;"
in which said Letters Patent there is contained a proviso, obliging us, the
said John Maberly and John Barrow, by an instrument in writing under
our hands and seals, or under the hand and seal of one of us, to cause
a particular description of the nature of our said Invention, and in what

page_text: manner the same is to be performed; to be inrolled in His Majesty's High
Court of Chancery within six calendar months after the date of the said
recited Letters Patent, as in and by the same (relation being thereunto had)
may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
John Maberly and John Barrow, do hereby declare that our said Invention,
and the manner in which the same is to be performed, is particularly described
and ascertained in and by the Drawings hereunto annexed, and the following
description thereof (that is to say):-
Our Invention for preventing the removal of carriage glasses by stealth
or otherwise consists in the application of a lever bolt connected with the
hinge of the carriage door, by which means the glass frame is bolted in
whenever the door is opened, and cannot be taken out but by unscrewing the
apparatus from the carriage.
Fig. 1 represents the application as it would appear on the inside of the
door supposing the pannel removed, to expose the apparatus, as fixed in the
door frame. In this Figure the lower end of the lever bolt projects forward
into the notch cut for that purpose in the glass frame, and prevents the glass
from being drawn up. Such is the situation of the bolt whenever the door is
opened.
Fig. 2 represents the application as it would appear on the inside of the
door, supposing the pannel removed to expose the apparatus, as fixed in the
door frame. In this Figure the lower end of the lever bolt is drawn back
out of the noteb, and the glass frame is liberated. This is the situation of the
bolt when the door is shut; the glass may then be drawn up.
Fig. 3 represents the front of the hinge with the sliding bolt affixed, which
acts against the lever bolt in a manner to be described hereafter.
Fig. 4, views, in three positions, of the sliding bolt, shewing its form.
Fig. 5 shews a section of the hinge when open, supposing it to be cut
through in the dotted line represented in Fig. 3. (a) the sliding bolt. (b) a s
projecting piece of steel which acts against the rounded part of the sliding bolt
when the hinge is closed. (d) the end of the sliding bolt acting against the
cylindrical part of the hinge when the bolt is drawn outward, and preventing it
from sliding.
Fig. 6 shews a section of the hinge, as in the last Figure, except that it is s
nearly closed. In this Figure the projecting piece (6) comes against the
rounded part of the sliding bolt (a), forcing the bolt back, there being a
hollow (c) provided to receive its end (d) within the cylindrical part of the
hinge when shut. Thus far the shutting of the hinge is described as forcing or

page_text: drawing the sliding bolt backward; it now remains to shew its connection with
the lever bolt which secures the carriage glass, and in what manner that security
is effected, which is, by the action of the bevel (e) of the sliding bolt acting
against and in the notch (f) at the upper end of the lever bolt in Figures 7.
Fig. 7 represents a perspective view of the lever bolt detached, looking on
the back of plate.
Fig. 7, the same, looking on the front of the plate, which lever bolt is to
be let into an aperture cut for that purpose in the framing of the door, a
section of which is represented in Figs. 1 & 2, and the plate screwed thereon,
as seen in Fig. 8.
Fig. 9 exhibits the back of the hinge, and the back of the lever bolt and
plate as it is to be connected in this situation, the hinge being open as
in Fig. 5; the sliding bolt is drawn outward, as in that Figure described.
Fig. 10 exhibits the back of the hinge, and the back of the lever bolt and
plate. When the hinge is shut in this situation (though not seen) the pro-
jecting piece (6) Fig. 3, &c. is acting against the sliding box, as Fig. 6, and
drawing it backwards in the manner described by that Figure. By referring
to Fig. 7 it will be seen there is a spring (9) forcing the lower end of
the lever bolt outward, which end introducing itself into the notch of the glass
frame, as Fig. 1, prevents the glass from being drawn up. But it is
obvious that if the bevel end of the sliding bolt (e), Figs. 4, 5, and 6, be
introduced between the upper end of the lever bolt and its plate at (f),
Fig. 7, the lower end of the lever bolt will be drawn considerably inwards.
Let Fig. 10 represent the binge, &c. as when the carriage door is closed, the
sliding bolt being drawn back, as before described in Fig. 6, and the bevel
end (e) thereof having forced itself between the upper end of the lever bolt
and its plate at the part (f), Fig. 7, the lower end of the lever bolt is conse-
quently drawn back, as in Fig. 2, out of the notch by which it did confine
the glass frame, and the glass may then be drawn up; but when the carriage
door (or the hinge) is opened, as in Fig. 5, the sliding bolt, by the force of the
spring (9), slips outward and releases the lever bolt, as Fig. 9 & 1, the lower
end of the lever strikes out into the notch, and the glass frame is then locked
or bolted, and cannot be drawn up.
In witness whereof, I, the said John Maberly, have hereunto set my
hand and seal, the Twentieth day of December, in the year of our
Lord One thousand eight hundred and fourteen.
