The article comprises a framework preferably
formed of wood burnings and a cover of ?exible
fabric, which for convenience will be referred to
r as canvas. The framework is adapted to be col
lapsed or folded into a compact space without
entirely removing the canvas. The canvas is so
constructed as to reinforce the framework as
well as‘ serve as the side and walls of the article.
This cover is adapted to be removed for repair,
cleaning, or replacement.

frame of ?xed dimensions having side bars l5, l5,
and end bars l6, Hi. The corner postsvl‘l, I1,
and l8, it are hinged to these side bars just
inside of the end bars by the simple expedient of
passing a side bar through the post and securing
it in place by an extension l9 which may be
pinned or glued or otherwise secured in place. It
will be seen that the element l9 constitutes‘ an
extension or part of the side bar beyond the
corner post. Movement in the other direction is
limited by the shoulder 20 (Fig. 12) which may
be formed integral with the bar l5 or formed
The two posts l1, l1 are connected not only by
the upper side bar l5 but by the lower side bar II
and may‘ also be connected by an intermediate
bar 22, both of the latter bars being permanently
secured in the adjacent comer post so that the
corner posts are held at ?xed distances with re
spect to each other. I therefore have a main '65
upper frame of ?xed dimensions and two swinging
side frames of ?xed dimensions, each of the side
frames including the upper side bars which are
parts of the main upper frame.
The corner posts are held apart by lower end
bars 23 which for convenience I will refer to as
spreaders. These bars are removable or detach
that the parts are ?rmly held, although because
able and may be jointed so as to facilitate inser
- tion and removal. For instance, each of these
of the ?exibility of the canvas and the resiliency
of the wood there is considerable leeway for
10 spreaders may be formed in two parts connected
by an interiorly threaded sleeve 24, the direction
of the threads on the opposite ends being re
versed so that by rotating the sleeve in one direc
tion the length of the spreader can be increased
and by rotating the sleeve in the opposite direc
tion the length may be decreased.
The upper ends of the corner posts at each end
of the crib are connected by a brace consisting of
an upper end bar or crossbar 25 and extension
post members 26. Each of these post extensions
is provided with a socket 21 to fit over the end of
a stud or projection 28 on the upper end of the
corner post. This brace, therefore, serves to hold
the upper ends of the corner'posts at ?xed dis
25 tances.
I preferably provide extension legs 30 which
are detachably connected to the lower ends of the
corner posts, for instance, by means of a screw
threaded extension 3| on the lower end of the
30 corner post which extends into a threaded socket
in the upper end of the leg. By this means the
body of the crib framework can be supported at
any height desired, depending upon the length of
the legs and their adjustment.
It should be understood, of course, that the
legs might be provided with anti-friction bear
ings or casters if desired (not shown).
The bottom and sides of the framework are
preferably enclosed by afabric cover preferably
40 of canvas, duck, or the like, which for conven
ience will be termed canvas. This canvas may
be formed of one or ‘more parts, for instance, of
three pieces, a main portion 32 and two end por
tions 33, which may be formed separately for
45 economical reasons, and sewed or otherwise se
cured together.
The central portion of the main web consti
tutes the bottom of the crib and the side exten
sions 34, 34 form the closed sides of the crib.
50 The edges 35, 35 are adapted to be secured to the
upper side bars |5, |5, preferably in a detachable
manner as for instance by means of snap fasten
ers, buttons or other attachment devices 36.
These fastening devices may be adjustable or a
number of them may be provided so that the
fabric can be stretched tight around the lower
side bars 2|, 2| and around the upper side bars
l5, l5 either inside or outside of the intermediate
bars 22, 22.
endwise from one crossbar 25 to the other be

By this arrangement although the various joints
of the frame do not need to be especially tight
the canvas cover embraces the upper and lower
side and end bars as well as the corner posts so

frame will stand steadily although on uneven
From the foregoing it will be seen that the
crib can be used with four legs or without the
four legs for convenience in carrying or if it is
desired to place the crib on a bed or table in the
manner of a basinette. Two of the legs at one
end can be removed and the crib set up in an
automobile with the remaining two legs resting
on the floor and the two corner posts resting on 20
the seat.
The crib can also be readily suspended from any
overhead support in the manner of a hammock
by attaching straps or chains, for instance, to
the side bars adjacent the corner posts. The 25
canvas sides may be provided with loops 44 or
pockets for convenient storage of various articles.
The end bars l6 constitute convenient means for
hanging towels, etc.
When it is desired to fold up and stow away the 30
crib the spreader bars 23 .are removed so as to re
lease the tension on the ends of the canvas cov
er, thus permitting the end braces with the post 1
extensions 26 to be lifted enough to disengage
the sockets 21 from the studs 28. These braces 85
may then be laid down on the upper side bars IS.
The corner posts and side frames can then be
swung around the side bars into the position
shown in Fig. 5. The parts may, of course, be
set up in reverse order.
In some cases it may be desirable to use a set
of springs such as 46. Such springs will have
end bars 41 which may be sprung between the
lower side bars 2| adjacent the corner posts and
serve as spreaders to hold the side frames from 45
folding inwardly.
It will be understood, of
course, that pressure upon the bottom web 32
either directly or through the springs tends to
increase the drawing-in tension of the canvas
cover and thus hold the side frames snugly in 50
In Fig. 8 the springs consist of sections con
nected by a cord 48. Each section consists of
side bars 49 connected by resilient cross bars
The side bars 49 rest on the canvas near 55
the side bars 2| and the cord passes through the
side bars 49 so that the spring is ?exible and
adapts itself to the body and permits the springs
_to be rolled up with the canvas or mattress or
folded for shipping.
The adjacent edges 31 and 38 of the main web
and the end pieces are secured together and the
edges 39 and 40 are secured together around the
corner posts, leaving an opening or hole 4| for
the lower end of each corner post which is thus

button or fastening device 42'so as to permit the
upper part of the side section to be inserted be
tween the bars 2| and 22. The upper edge 43 of
each end piece is secured to the cross-bar 25 of
76 the brace member so that the cover is stretched
The ends of the crossbars 49’ are set into the
bored at the same time as the side bars so that
the cord may pass through the ends of the cross
crossbars in case they become unglued.
It will be seen that the canvas side and end
walls furnish protection against drafts of air.
The sides may, however, be provided with holes
for ventilation if desired.
In some cases it is desirable to have a sunshade
or shield over one end or both ends of the crib.
Such a shield may conveniently consist of a
U-shaped frame hinged to one of the spreader
bars 23 and a suitable shelter top 59.

The frame consists of side bars 5| and a socket to receive the ball-like end of the toggle
crossbar 52. The side. bars are hinged, on the member 23". This forms a. hinge-like connec

manently connected together. The side frames
in this case consist of corner posts 63, 63 with
20 one or more connectingside bars such as 64 and
65. Removable spreader bars 66 are provided be
tween the lower ends of the corner posts. The
post sections 62 and 63 are provided with‘tele
scopic stud and socket connections to hold the
25 respective parts in alignment. It will be under
stood that the canvas covering is secured on this
framework in a manner similar to the one pre
viously described.
The upper edges of the can‘vas will be connected
preferably to the side bars 60, 60 and the end
bars 6|, 6| and ?t around the corner ‘ posts and
the lower bars 65, 65, and 66, 66 so as to hold the
parts together.
If desired extensible means of connection be
tween the post sections 62 and 63 may be pro
vided so as to make it possible to stretch the
canvas. Such an extensible joint maybe ef
fected by means of a threaded insert 61 between
the members 62 and 63 as shown in Fig. 15. By
turning this section one way or the other the
upper section of the corner post may be
raised or lowered.
It should be understood that the canvas may
attachment and detachment of the legs.
While the invention in its preferred form con
templates the combination of the wooden frame 20
work and the canvas covering, it should be under
stood that some of the advantages of the inven
tion may be attained by the use of the framework
together with a spring for forming the bottom
of the crib, in which event the upper brace 25
members might be held down by means of straps
or other suitable devices.
While a crib isnormally of greater length than
width, it should be understood that the article
may be of the same length was width or even 30
greater width than length, so that the‘ terms
ends and sides are interchangeable. Actually the
article has four sides, two of which are for con
venience in distinction called ends.
It should also be understood that while I pre 85
~fer to provide leg extensions for the corner posts
so as to support the crib in an elevated position
these leg extensions, might be entirely omitted
and the crib used as ‘a play pen.
While the crib is intended primarily for babies 40
it may be used in the smaller sizes for dolls and
in larger sizes for children.
The chair shown in Figs. 17, 18., and 19 em
bodies some of the features of the crib of Fig. 10
but the frame is inverted. The lower part of ?xed 45
relation consists of corner posts 10, 10, and ‘H,
‘H connected respectively by the rear bar 12,
be ornamented in any desired manner and that
any suitable fabric either of close or open mesh
work may be employed, depending upon whether
it is desired to prevent drafts or ventilate the
sides. In fact, the cover may be of perforated ' the front bar 13 and side bars ‘l4, 14. The rear
material or portions might be made of strips so corner post sections 15, ‘I5 are connected to the
long as su?icient strength is provided for tieing
the side bars and end bars together and drawing
the lower side bars against the Spreaders. Such
a construction avoids the possibility of accidental
collapse and provides no openings into which a
child might thrust its head.
In the construction shown in Fig. 16, the cor
ner'posts l1 and I8 are detachably connected
at their upper ends as in Fig. 1_ by a bar 25 and
post sections 26. The lower ends of the posts l1
and I8 are held apart by the detachable spreader
‘bar 54 and drawn together by a rod 55 which
has a knob 55' at one end and is threaded at 55"
to screw into the post l8.
In such a construction the canvas body may
be omitted and the top bar 25 held down by tie
rods 56 through which the spreader 54 and draw
rod 55 extend. The end of the crib may be closed
'by upright rods or slats 51 which connect the.
top bar 25 and the spreader 54. The sides may be
closed by upright rods or. slats 59 which connect
the lower side bar 2| and the intermediate bar 22'.
In the form of spreader shown in Fig. 11 the
part 23' is ?xed in or formed as a part of one end
of the body portion 24', the opposite end of which
has a semi-cylindrical groove terminating in a
front corner post sections '16, 16 by the side bars 50
11, ‘I1, and ‘l8, 18 forming side frames. The sec
tions such as 15 and 10 are detachably connected
by plug and socket parts ‘I9 and 80. The upper
ends of the back posts 15, 15 are connected by
a crossbar 8| and corner post extensions 82 which
detachably fit the upper ends of the posts 15, ‘I5.
Suitable spreaders 83 and 84 are interposed be
tween the corner posts for the same purpose as
the spreader 23 of Fig. 4 and the spreader 66
of Fig. 13.
The canvas cover consists of a strip 90 ‘having
its ends detachably secured to the bars 12 and
‘I3 by looped fastenings 9| and 92 and a cross
cover 93 with its ends,94, 95 secured detachably
to the side bars 14, ‘H.
These two strips 90 and 93 are preferably se
cured together across the top to form the seat
of the chair and the edges are united or con
nected together at 96 around the corner posts
to hold the-posts together. The main web pref
erably has a central opening 91 to receive a re
ceptacle and straps 98 to support the receptacle
with itsusual flange resting around the edge of
the opening. A cover ?ap 99 may be provided 75
if desired so as to completely conceal the re
ceptacle, and fastened at I00 to the seat.
The arms 18 are preferably removable to fa
cilitate the removal of the canvas cover but it
should be understood that the two strips of canvas
90 and 93 might be detachably connected together
so that they could be removed without taking out
the arms ‘I8.
I preferably provide a canvas back llll, also
10 secured at 100 to the seat at or near the rear and
passed over the top bar BI and connected, for
instance, by straps I02 to the buckles I03 on
the flap 9| so that the back and seat can be
stretched at the same time.
It will be seen that the side bars and frames
correspond with the side bars and frames of the
crib and that the front and back bars correspond
with the end bars of the crib and that the canvas
holds the parts together in the same general
20 way as in the crib.
As the canvas embraces not only the side and
end bars but also the corner posts, the parts
are securely held together even when the glue
in the joints works loose. A very satisfactory
25 construction can be made in this way without
the use of nails, screws or hardware ?ttings of
any kind.
