IMPROVEMENTS IN 'SAFETY BRAKE APPARATUS ' FOR PERAMBULATORS AND OTHER SIMILAR VEHICLES."
Year: 1875

page_text: LETTERS PATENT to Charles Ingrey, of Chandos Chambers, Buck-
ingham Street, Strand, in the County of Middlesex, Engineer,
for the Invention of "IMPROVEMENTS IN 'SAFETY BRAKE APPARATUS
'
FOR PERAMBULATORS AND OTHER SIMILAR VEHICLES."
PROVISIONAL SPECIFICATION left by the said Charles Ingrey at
the Office of the Commissioners of Patents, with his Petition, on
the 15th October 1875.
I, CHARLES INGREY, of Chandos Chambers, Buckingham Street,
Strand, in the County of Middlesex, Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN ' SAFETY' BRAKE
APPARATUS FOR PERAMBULATORS AND OTHER SIMILAR VEHICLES," to be as
follows:-
:-
This Invention is designed to prevent such accidents as result from
the uncontrolled movement of perambulators and other similar vehicles,
as for instance when left unattended or when released by the person in

page_text: charge whilst on an inclined road or way. For this purpose I connect
to a bar or lever attached to the handle of the vehicle a bolt or catch
pressed by a spring (or by weight) towards the wheel boss, and arranged
to operate in connexion with a series of radial holes or recesses around
the wheel boss in such manner as that whilst the handle is properly
held by the person in charge the bar or lever will be pressed towards
the handle, thus holding the bolt or catch out of gear with the wheel
boss or attachment, but that on the handle and bar or lever being
released the bolt or catch shall automatically move towards the wheel
boss or attachment, and by entering one of the radial holes or recesses
instantaneously arrest the rotation of the wheel.
The radial holes or recesses may be formed in the wheel boss itself, or
in a cap or ring attached to the wheel.
The bolt or catch may be in the form of a spindle, having collars, and
arranged in combination with a spring carried by a bracket or holder
attached to the axle shaft, the bolt or catch being connected to the bar
or lever of the handle by a cord or otherwise; or a heavy or weighted
catch somewhat resembling a pawl, and attached by cord or otherwise
to the said bar or lever may be used.
The bar or lever is by preference made to conform to the shape of
that portion of the handle against which it is to bear, and is hinged or
jointed to the under part of the handle.
It will be evident the arrangement of my improved safety brako
apparatus may be modified in various ways to suit the requirements of
particular applications without departing from the distinctive character
of my Invention as above set forth. Also that my apparatus may be
applied to one or more of the wheels in a perambulator, invalid carriage,
or other similar vehicle.

Letters Patent, bearing date the Fifteenth day of October, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Charles Ingrey, Her special license, that
I, the said Charles Ingrey, my executors, administrators, and assigns,
or such others as I, the said Charles Ingrey, my executors, admini-
strators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term 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 SAFETY' BRAKE
APPARATUS FOR PERAMBULATORS AND OTHER SIMILAR VEHICLES," upon the con-
dition (amongst others) that I, the said Charles Ingrey, 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 Charles Ingrey, 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 thereof, and the Sheet of Drawings therein
referred to (that is to say)
:-
This Invention is designed to prevent such accidents as result from
the uncontrolled movement of perambulators and other similar vehicles,
as for instance when left unattended or when released by the person in
charge whilst on an inclined road or way. For this purpose I connect
to a bar or lever attached to the handle of the vehicle a bolt or catch
pressed by a spring (or by a weight) towards the wheel boss, and
arranged to operate in connexion with a series of radial holes, recesses,
or notches around the wheel boss in such manner as that whilst the
handle is properly held by the person in charge the bar or lever will be
pressed towards the handle, thus holding the bolt or catch out of gear
with the wheel boss or attachment, but that on the handle and bar or
lever being released the bolt or catch shall automatically move towards

page_text: When my Invention is applied to wheels having metal bosses the cap
or ring may be attached by clips passing around the spokes.
Fig. 11 shews a modification which will be readily understood from
the Drawing without further description.
It will be evident the arrangement of my improved safety brake
apparatus may be modified in various ways to suit the requirements of
particular applications without departing from the distinctive character
of my Invention, as above set forth. Also that my apparatus may be
applied to one or more of the wheels in a perambulator, invalid carriage,
or other similar vehicle.
Having described the nature of my said Invention, and explained the
manner of carrying the same into practical effect, I hereby declare
what I consider to be novel and original, and therefore claim as the
Invention secured to me by the herein-before in part recited Letters
Patent is, the application and use of a bolt or catch carried by a bracket
or holder attached to the axle shaft, said catch or bolt being arranged
to operate in connexion with holes, recesses, or notches arranged around
the wheel boss, all substantially as herein-before described and illustrated
for the purposes specified.
In witness whereof, I, the said Charles Ingrey, have hereunto
set my hand and seal, this Thirteenth day of April, in the year
of our Lord One thousand eight hundred and seventy-six.
