follows
-
It relates to Infants' Churs and has for its object their construction in such a
manner that they may be quickly and safely converted from high to low stationary
churs and from either of these to rocking chairs or to chairs running on wheels or
castors and vice versa
To the lower end of each of the four legs of the chair is attached a curved rocker
which is pivoted near its centre against the outside of the leg by means of a bolt,
screw, or rivet passing through both and thus allowing the rocker to assume various
positions
At the one end of each rocker and projecting on its inside edge is fixed a small
wheel upon which, when the rockers are turned with that edge downwards the
chair travels but when the lockers are reversed so that their rounded or outside edge
comes downwards they form a continuous curve for the rocking chair
in both of
which cases the front and back rockers for some portion of their length lie side by
side
The two back rockers are secured together by means of a cross bar and also the
two front rockers in similar minner and these cross bars coming against the frame-
work of the chau assist in holding the rockers in various positions
The footrest of the chair is carried upon two bars which are pivoted on the inner
side of the framework of chair thus allowing the foot-rest to rise and fall and by
means of notches in these bars or levers attached to them to secure or release the
crossbars connecting the rochers aforementioned
Upon the inside of each front leg is fixed lever which is pivoted near its centre
and works in a slot provided for the purpose this lever is in a slightly oblique
position from the leg and projects in the front at its upper ind in the back at its
lower end against its lower end spring is placed which presses that end towards
the hack leg of the chur

I, JOHN WFSLEY CLIFT of Tan Bank, Wellington, in the County of Shropshire,
Carriage Manufacturer, do hereby declare the nature of this invention and in whit
manner the same is to be performed, to be particularly described and ascertained in and
by the following statement
-
My Invention relates to that Class of Infants' Churs which are convertible from
stationary to moveable chairs and are adjustable at will to various heights and
positions and has for its object their construction in such a manner that they may be
quickly and safely adjusted to their various positions
On the accompanying drawings Fig 1 shows the side elevation Fig 2 shews a
half section of the front elevation Fig 3 shews the lower portion when arranged as i
travelling chau Fig 4 shews the lower portion when arranged as a rocking chair,
and Fig 5 shews a half section of the lower part of chair as viewed from underneath
when arranged as in Fig 4
The seat of the chair is constructed of such dimensions that its width cross the
back and including the two hind legs is nearly equivalent to its width cross the front
and between the two front logs thus bringing the flat outer side of each hind leg
nearly in a plane with the flat inner side of its corresponding front leg
Upon the outer side and at the lower end of each of the four legs is pivoted (at or
neu its centre 1 curved rocker A and A' which is so free to revolve upon the bolt or
rivet attaching it to the leg th it it can be made to assume the various positions shown
in Figs 1, 3, and 4 and it will be observed that in the two litter case the front and
back rockers respectively overlap each other and lie side by side for portion of their
length
The two hind rockers are united at their shorter ends by a cross bir B, screwed
simular manner
ag unst their concive edge ind the two front rochers are united in
by a cross bar B¹, and when used as a high chair these cross bars coming against and
extending across the outer edges of the chair legs prevent the rockers from spreading
wider apart at their lower extremities or when used as 1 rocking chur they
similarly extend across and press against the lower edges of the side framing of the
chair, as shown in Figs 4 and 5, the crossbus in either case being still further
secured and held in position by the locking devices hereafter described and illus
trated by the drawings
The footrest of the chair is carried upon two arms C, which are pivoted at any
point at the rear of the footrest and preferably against the inner side of the hind legs
as shown in Fig 1 at "p" Under the footrest these, arms are notched on their lower
edges to receive the front cross bar B¹ so that when the footrest is pressed down these
arms seize upon and hold the cross-bar, and with it the front rockers, in an upright
position (as shown in Fig 1) from which they cannot be released until the footrest is
raised
Upon the inner side of each front leg (and preferably working in a slot formed for

page_text: the purpose between it and the vertical piece of wood D as shown in Fig 2) IS
pivoted at or near its centre metal lever E having its lower end bent outwards to
forin a hook "h' and being acted upon at that end by spring
" "which pressing
agunst a stud, or other projection of the lever, tends to force the lower end of the lever
towards the hind chair leg and thus bring the lever into position more oblique to
the front leg of the chur The levers are provided at their lower end with i
notch for receiving the projection at the end of the metal stay F (carrying the
bind wheel) as shown by dotted lines in Fig 4
Underneath each end of the footrest is fixed flit metal plate G, the end of
which wears against the upper front edge of the lever E to prevent the edge of the
footrest from being worn by sliding up and down against the edge of the lever
When the footrest is raised, the metal plate G pressing gunst the edge of the lever E
brings it to a position less oblique to the front leg a faint notch at the upper end of
the lever retaining the plate and footrest from filling until the chair is adjusted to
the desired position, iftei wluch the footrest is agun lowered
Upon the inside of the lower side framing of the chair on either side is pivoted
horizontal lover L (the position of which and its direction of movement are shown by
dotted lines in Fig 1) having a notch or other device it its free end for engiging
with the projecting lower end of the metal stay when the chan is ringed is in
Fig 1 (the form of the metal stay 1 is best seen in Fig 5) At thur front ends
the levers L are connected with the arms C above them, (carrying the footiest), by
meins of the vertical links N and uc thus tuned upon their pivots by the action of
the footrest
At the upper end of each hind rocker, and extending cross the cross bar B, is fixed
the metal sy F for carrying the lund wheels, the lower end of this stay ongiges
with the horizont il lever L as before described while the upper end forms 1
projection beyond the centre of the wheel for engaging with the notch in the vertical
level when arranged is a 1ocking chai
When iri inged is travelling chin (big 3) the bich ends of the front rochers
are supported upon small anglo plates Pwed agunst the hund rockors which
in then turn ire supported upon the hooked lovers D Or these ends of the rockers
may be allowed to pass the ingle plates and hooked levels and rest upon the floor
making a low fixed chun supported upon light points, uz - the four wheels and the
four tice ends of the 10chers
the
When ringed as a rocking chun (Fig 4) the front lockers revolve until the
cross bar uniting them comes round and rests gunst the lower edge of the side
framing of the chun, the hind rockers ue then brought round in a similar way
met il stays at their extremity coming across the front crossbar B' hold it firmly in
position while they in the tun u seized upon and held by the notches in the
vertical levers E immediately the footrest is low cred
The two pieces of wood forming the side training of the chair are united by a board
"K extending cross the upper edges and serving as a platform upon which to
place a utensil when required this board or platform also serves as stop to the
front end of the horizont il levels L to check the upward movement of the footrest,
besides giving greater rigidity to the chair
From the foregoing description, then in connection with the diawings it will thus
have been made clear that when the footrest 15 rused the chur can be adjusted to any
of its desired positions, but th it when the footrest is lowered the chair is locked by
the action of the appliances aforementioned
Having now particularly described and iscertained the nature of
my sud
Invention and in what manner the same is to be performed, I declare that what
I claim is
1 In a chau of the class referied to, from auxiliary legs or locker pieces so
pivoted ag unst the chair, that either their concave or their convex ɩdøes may at will
