IMPROVEMENTS IN OR RELATING TO PER- AMBULATORS
Year: 1876

page_text: LETTERS PATENT to James Newbery Blamphin, of Liverpool, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN OR RELATING TO PER-
AMBULATORS."
Sealed the 26th January 1877, and dated the 31st July 1876.
PROVISIONAL SPECIFICATION left by the said James Newbery Blamphin at
the Office of the Commissioners of Patents on the 31st July 1876.
JAMES NEWBERY BLAMPHIN, of Liverpool, in the County of Lancaster. " IMPROVE-
MENTS IN OR RELATING TO PERAMBULATORS."
This Invention relates more to children's perambulators than to those for invalids.
It consists,
First. In a second seat entirely independent of the perambulator. The sides of
this seat are so designed as to just fit inside the sides of the perambulator, a pro-
jecting piece behind on each side fitting securely under the back or stationary seat,
and the other end being secured to the front part of the body of the carriage by
thumbscrew, spring, or catch. Below this extra seat the back of the removeable
part is entirely open, so that the legs of the occupant of the hind seat can lie
comfortably below the adjustable seat in front, and thus have to all intents and
purposes as much room as before; thus, without the removeable seat, the apparatus
is an ordinary single seat perambulator; insert the new apparatus, and it imine-
diately becomes a double seated one, both seats facing the same way.
2nd. In the back seat I omit upholstering near the bottom of the back so as
to allow room for the clothes of the occupant. The child can thus sit far more
comfortably than when obliged to occupy the front portion of the seat to make
room for his clothes behind.
3rd. Similarly in the front seat I prefer to leave a clear slit or hole back of the
seat near the bottom so that the clothes of the first child can stick out through, and
thus not incominode him.
4th. I apply a brake preferably to the front wheels in the following manner :-
The brake block is kept by means of a spring constantly pressing against the wheel,
except when held back by force. A cord or line of any convenient material is
fastened to the block or spring, or so arranged that by pulling it a counteracting
force is brought to bear on the spring, so that it no longer presses the brake against
Price 6d1

page_text: the wheel. This cord is passed over small guide pulleys to a hook and trigger or
-ōther similar arrangement at the back of the porambulator. When the brake is
not required the spring is forcibly drawn back by the string, which latter is securely
caught and held by the hook or knob behind; the instant however the trigger or
knob is pulled or pushed, as the case may be, the string and with it the spring is
released, and the full force of the brake is instantaneously applied.
5th. In making my perambulator I usually put up two separate sunshades, one
for each of the two seats, that belonging to the front seat being removeable with
said seat. Each sunshade is made to turn on pivots at the side, so as to be brought
forward or backward at pleasure.
I purpose to call my perambulator the Patent convertable safety perambulator.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said James Newbery Blamphin in the Great Seal Patent Office on the 30th
January 1877.

MENTS IN OR RELATING TO PERAMBULATORS."
"IMPROVE
Fig. 1 shows an elevation of my perambulator; Fig. 2, a side view of front seat
detached; Fig. 3, back view of same; Fig. 4, front view; Fig. 5, side view; Fig. 6,
back view of apparatus operating the brake.
This Invention relates more to children's perambulators than to those for invalids.
It consists,-
First. In a second seat A.entirely independent of the perambulator. The sides
of this seat are so designed as to just fit inside the sides of the perambulator, a
projecting piece B behind on each side fitting securely under the back or stationary
seat, and the other ends being secured to the front part of the body of the carriage
by thumbscrew, spring, or catch. Below this extra seat the back of the removeable
part is entirely open, so that the legs of the occupant of the hind seat can lie
comfortably below the adjustable seat in front, and thus have to all intents and
purposes as much room as before; thus, without the removable seat, the apparatus
is an ordinary single seat perambulator; insert the new apparatus, and it imme-
diately becomes a double seated one, both seats facing the same way.
2. In the back seat I omit the upholstery near the bottom of the back so as
to allow room for the clothes of the occupant. The child can thus sit far more
comfortably than when obliged to occupy the front portion of the seat to make room
for its clothes behind.
3. Similarly in the front seat I leave a clear space or hole E, Fig. 3, back of
the seat near the bottom, so that the clothes of the 1st child can pass through, and
thus not incommode him, as before described.
4. I apply a brake F, preferably to the front wheel in the following manner :-
The brake block is kept by means of a spring G continually pressing against the
wheel, except when held back by force. A cord or line H of any convenient
material is fastened to the block or spring, or so arranged that by pulling it a
counteracting force is brought to bear on the spring, so that it no longer presses
the brake against the wheel. This cord is passed over small guide pulleys to a
hook and trigger or other similar arrangement at the back of the perambulator.
A good form of trigger is shown at Figs. 4, 5, and 6. J is a spring; K, slotted
plate L, button; M, handle to pull up the cord and so take the brake off. The
spring J is slotted for detent N, so that if the brake be off, pressing back the button
instantly releases it, and the brake springs back to the wheel. When the brake is
not required the spring G is forcibly drawn back by the cord, which latter is securely
caught and held by the hook N acting on spring catch J.
5. In making my perambulator I usually put up two separate sunshades, one

page_text: for each of the two seats, that belonging to the front seat being removeable, with said
seat. Each sunshade is made to turn on pivots at the sides, so as to be brought-
forward or backward at pleasure.
I propose to call my perambulator the "convertable safety."
Having now described my Invention, and the best mode known to me of carrying
it into effect, I beg to state that I do not claim the method of upholstering. the back
seat, nor yet the sunshades, as these are not necessary parts of my. Invention, but
what I believe to be new and desire to claim under the herein-before in part recited
Letters Patent is,―
1st. Arranging a perambulator as described, so that a second removeable seat can
be attached to or detached from the front at will, both seats being arranged to face
the same way.
2nd. The seat A and the special arrangement for accomodating the clothes of the
child behind, substantially as described.
3rd. The spring catch, substantially as and for the purposes described.
4th. The mode described of applying a brake to a perambulator, in which it is
kept pressing against the wheel by a spring at a state of tension when not pulled
up or held back by a spring catch or its mechanical equivalent.
In witness whereof, I, the said James Newbery Blamphin, have hereunto set
my hand and seal, this (Twenty-ninth) day of January, in the year of our
Lord 1877
