Improvements in Perambulators.
A communication from AUGUST SCHNEIDER, of Niederplanetz, Saxony, in the
Empire of Germany, Basket-maker.
J, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., do hereby declare the nature of this invention to be as follows:-
The subject of this invention is a baby-carriage or perambulator of the shape
of a cradle (bassinet) capable by the removal of part of the body of being
converted into a chair rolling on three wheels.
The body or "bassinet" of the perambulator has a removable portion retained
in place by suitable devices such as pivotted hooks while the perambulator is to
preserve the cradle shape; when it is to be transformed into a chair the hooks
are released and the portion removed. In this case a seat is secured at the back
of the vehicle. The hood may be secured to the perambulator on either side or
it may be replaced by frame-work surmounted by an awning especially in the
case of the chair arrangement. The bassinet portion is preferably adapted to be
folded out of the way when not in use.
The front axle is supported by the springs in the following manner. Each of
the springs carries a bearing with a square perforation for the reception of the
axle also square in section. A spring catch completes the fastening. The spring
catch upon being disengaged may freely turn upon its pivot so as to permit the
removal of the axle.
One of the wheels may then be removed from the axle and arranged in the
centre line of the vehicles between the springs.
Above the bearings of the axle the springs carry sockets in which bolts are adjust-
ably fitted, a spring having the tendency to compress these bolts, i.e. to press each
towards the centre. To obtain an engagement of the bolts with each other one
of them may carry an offset or projecting pin fitting a corresponding recess in
the end of the other. When these bolts are moved apart upon overcoming the
pressure of the springs the wheel with its nave is inserted into the space between
the sockets; whereupon the bolts being released from the pulling strain, the
springs are allowed to draw them together again so that they form the axle for the
inserted wheel.
The spring-bolts may if desired be replaced by a single rod or spindle passed
through the sockets which in this case should contain no spring and which rod will
similarly act as the axle. The rod may be secured against slipping or displace-
ment by nuts screwed to its ends or other suitable means.
Structural modifications may of course be made in the arrangement without
departure from the spirit of the invention.

A communication from AUGUST SCHNEIDER, of Niederplanetz, Saxony, in the
Empire of Germany, Basket-maker.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex
Member of the Institution of Mechanical Engineers do hereby declare the nature of
this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
The subject of this invention is a baby-carriage or perambulator of the shape
of a cradle (bassinet) capable, by the removal of part of the body of being
converted into a chair rolling on three wheels.
In the accompanying drawings
Fig. 1 is a side elevation of the improved vehicle arranged as a four-wheel
perambulator with the removable portion.
Fig. 2 is a side view thereof arranged as a three wheel perambulator or rolling
chair and without the removable portion.
Fig. 3 is a front view of the same when converted into a three-wheel
perambulator or rolling-chair, and
Figs. 4 to 9 are detail views.
A is the body or "bassinet" of the perambulator. The removable portion a a¹
is retained in place by suitable devices such as pivotted hooks a while the
perambulator is to preserve the cradle shape (Fig. 1); when it is to be transformed
into a chair the hooks a² are released and the portion a a' removed as in Figs. 2
and 3. In this case a seat is secured at the back of the vehicle. The hood c
may be secured to the perambulator at either end or it may be replaced by frame-
work surmounted by an awning c³, especially in the case of the chair arrangement
as in (Fig. 2). The bassinet portion a a' is preferably adapted to be folded out of
the way when not in use.
The front axle d is supported by the springs e in the following manner.
A
Each
of the springs e as shown in Figs. 4 and 5 carries a bearing e¹ with a square
perforation or recess for the reception of the axle d also square in section.
spring plate e pivotted at e³ and engaging with a stud or projection et by means of
a recess or perforation completes the fastening. The spring catch or plate e upon
being disengaged from the stud et may freely turn upon its pivot e so as to permit
the removal of the axle from e'.
One of the wheels may then be removed from the axle d and arranged in the
centre line of the vehicle between the springs e as shewn in Fig. 6.
Above the bearings of the axle d the springs carry sockets g in which bolts are
adjustably fitted a spring g' having the tendency to compress each of these bolts,
i.e. to press it towards the centre. To obtain an engagement of the bolts h with
each other one of them may as shown carry an offset or projecting pin fitting a
corresponding recess in the end of the other. When these bolts are moved apart
upon overcoming the pressure of the springs the wheelf with its nave is inserted
into the space between the sockets g; whereupon the bolts being released from
the pulling strain the springs g₁ are allowed to draw them together again so that
they form the axle for the inserted wheel.
The spring-bolts h may if desired be replaced by a single rod or spindle i passed
through the sockets 9 which in this case should contain no spring as shown in
Figs. 8 and 9 and which rod will similarly act as the axle of f. The rod i may 4
be secured against slipping or displacement by nuts screwed on to its ends or other
suitable means.
Structural modifications may be made in the arrangement without departure from
the spirit of the invention.

page_text: Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent and in what manner
the same is to be performed I declare that what I claim is :-
A baby-carriage which by the removal of a portion a a' may be converted into
a rolling-chair or which may be converted into a three-wheeled vehicle, the
removable fore-axle d being for this purpose detached from the springs e and one
of the wheels f being moved so as to coincide with the longitudinal axis of the
vehicle and there locked between sleeves g and retained in position either by pins h
acted upon by springs g' or by means of a rod i substantially as described and
illustrated in the accompanying drawings.
