Improvements in Perambulators or Children's Carriages.
I, WILLIAM HENRY RICHARDSON, of 618 N. Spring Street in the City of Baltimore
and State of Maryland, United States of America, Manufacturer, do hereby declare
the nature of my invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
This invention relates to certain improvements in that class of children's carriages
in which the body thereof is reversible in position with reference to the running
gear.
The said invention consists, first, in improved means for elevating the body
whereby it may be reversed in position, and, secondly, in means for limiting the
movement of the body to a half revolution so as to prevent careless and incompetent
nurses from turning the body on its axis to the detriment of the occupant, as will
hereinafter fully appear.
In the further description of the said invention which follows, reference is made
to the accompanying drawing forming a part hereof and in which,
Figure 1 is an exterior side view of the improved carriage, and Fig. 2 a sectional
side view of the same. Fig. 3 is a cross section of Fig. 1 taken on the dotted
line, x-x.
Figs. 4 and 5 are enlarged details of certain parts of the invention.
Similar letters of reference indicate similar parts in all the figures.
In the said drawing, A is the body of the carriage, which is represented as formed
of wicker work with a solid bottom.
The body, A, is seated on a tray, B, supported by springs, a, from the side bars, C,
to which the axles, b, are attached.
D is a king bolt having a plate, c, at its upper end secured to the bottom of the
body as shown in Fig. 2. This king bolt passes loosely through a socket, d, in the
bottom of the tray, and is connected at its lower end with the short arm of the lever, E.
The end of the long arm of the lever, E, is within convenient reach of the attendant
or person pushing the carriage. By means of this lever, the body of the carriage
may be elevated above the tray, as shown in Fig 2 and then turned so as to bring
either the face or back of the child towards the nurse.
The reversed positions of the body are indicated by dotted lines in Fig. 2.
In the drawing the stand G which forms the fulcrum of the lever, E, is attached
to the bottom of the tray but it is evident that the lever could be fulcrummed from
the side bars, C, or the axles.
To compensate for the vibration of the lever, E, as the body is elevated, I fork the
end of the lever and curve the parts thereof which come in contact with the collars, f,
on the king bolt.
In the present invention, the tray, B, may be provided with sides to hold the body
in place, the said sides being formed of rods supported from the bottom by means of
suitable brackets, which are flared outwardly to facilitate the seating of the body.
The preferred means however, consist in pins, g, on the top of the tray adapted to
enter sockets, h, in the bottom of the body, as shown in Fig. 2.
To limit the movement of the body to a half revolution, for the purpose described,
I secure to the upper collar, f, the arms, k, having the stud, n. As the body is brought
into either of its proper positions, one of the studs strike against the side of the
lever, E, and further movement in the same direction is prevented.
To allow for the thickness of the lever E, it is necessary to place the studs, n, at
more than 90 degrees apart or each from a diametrical line a distance equal to half
the thickness of the part of the lever, E, with which they come in contact. This
arrangement of the studs is shown in Fig. 5, which is an underside view of the upper
collar, f, and its arms and studs.

page_text: I do not limit myself to the devices shown for preventing a full revolution of the
body of the carriage when it is elevated above the tray, as it is evident that other
means could be employed for the purpose, my invention extending to a stop which
is operative to prevent the rotation of the body when in an elevated position.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :-
J. In a child's carriage, a tray supported from the running gear combined with a
body provided with a king bolt which passes through the said tray and a lever
connected to the said king bolt whereby the same may be elevated so as to admit of
the body being turned and reversed in position with reference to the running gear,
substantially as, and for the purpose specified.
2. In a child's carriage, the body thereof susceptible of a vertical movement
from its foundation by means of a king bolt which also serves as the pivot of the
said body in its reversal with reference to the said running gear, substantially as,
and for the purpose specified.
3. As means for elevating the king bolt, D, the lever, E, fulcrummed to the stand, G,
and forked at its end through which the said king bolt passes, and curved faced
collars, f, on the said king bolt, whereby the change in angular position of the lever
in its operation does not deflect the said king bolt from a vertical position, substan-
tially as, and for the purpose specified.
4. In a child's carriage, the body thereof susceptible of a vertical movement from
its foundation, and a rotative motion when in an elevated position, combined with a
stop to limit the rotative motion to less than a full revolution, substantially as, and
for the purpose specified.
5. In a child's carriage, a platform or tray supported from the running gear, a body
pivoted to the said tray, and adapted for elevation from the said tray, combined with
a stop to limit its rotation or rotative movement, substantially as, and for the purpose
specified.
6. The bolt, D, having the arm, k, with the studs, n, combined with the elevating
lever, E, substantially as and for the purpose specified.
7. The bolt, D, having the arms, k, with the studs, n, the said studs being moved
from a diametrical line, combined with the elevating lever, E, substantially as, and
for the purpose specified.
8. In a child's carriage, the body thereof adapted for elevation from a tray, combined
with pins and sockets attached respectively to the said tray and body, substantially
as, and for the purpose specified.
Dated this 17th day of May 1889.
