PROVISIONAL SPECIFICATION.
Improvements in Iron Folding Bedsteads.
I, JAMES MONTGOMERY, of 600, Mildred Avenue, Chicago, in the County of
Cook and State of Illinois, United States of America, Machinist, do hereby
declare the nature of this invention to be as follows:-
Figure 1 shows my improved folding bedstead in side elevation.
Figure 2 shows Figure 1 when folded.
Figure 3 shows the head of my said bedstead, partly in section, to show the
operating mechanisin of the canopy.
Figure 4 shows the jointed leg of the foot-end of the bedstead, as seen from
the inside in looking from the head end.
Figure 5 shows a side rail with a part of its woven wire mattress, or spring,
and its trausverse supports, in plan view.
Figure 6 shows a transverse bar with its coiled supporting springs, the woven
fabric above it, and the chains which connect the supporting bar and woven
fabric.
Figure 7 shows a modification of the joint in the side rail in side view.
Figure 8 shows Figure 7 in plan view.
Like reference letters denote like parts throughout.
The object of my invention is to provide an iron folding bedstead having a
woven wire mattress.
To attain said desirable end I construct my said new bedstead in substantially
the following manner, namely:-The tubular posts a have the usual T-shaped
pipe-fixtures a¹ into which are screwed pipe-pieces d into which slide pipes or
rods e secured in elbows f provided with legs which are connected by a cross-
rod and inside of the parts d, e, f, is the side-rail & pivoted at f' to the elbow f
and hinge-jointed at 7 and c between the parts and f.
The foot-end posts have their Ṭ-shaped fixtures to which the rails bare
attached. Said fixtures r have each a hole with a slot h h into which slip the
upper ends of the legs secured by a pin i on which said leg turns.
To the transverse leg-connecting rods j' is attached a rod k and to the
inner rode or any of the moving parts f, f, g, is attached a cord n passing under
the pin 7 theuce up through the post a and out over a pulley o near the top of the
post and to a canopy m hinged at m³.
Cross-bars t connected to the sidebars hold the woven wire fabric to on springs u.
The fabric is held to the bars by chains vor equivalent mechanism and one
of the bars near the joint holds the fabric down and from stretching directly
across from end to end, thus enabling a single person to extend the bedstead
and sufficiently stretch the woven fabric for use, a feat otherwise impossible when
the web reaches directly from bar to bar at its ends as any such tension would
tend to raise the head-end of the bedstead.
In Figures 7 and 8 cc shows another form of hinge joint in rail b. The web w
must have sufficient tension to make it useful, this is attained by my hinge-

page_text: jointed and pivoted side-rails fulcrumed at the reciprocable intermediate supports
at, thereby forming a toggle-joint of great power.
The bedstead is folded by raising the foot-end which depresses and opens the
joints at c and shortens the space between a and g whereby the rod k brings the
legs inward and parallel to the bars b. Said inward motion of the legs g
slackens the cord n and thus allows the canopy m to move from its elevated posi-
tion, shown in broken lines, to the position shown in full lines in Figures 2
and 3. Said canopy is here shown as a wire or rod to which a curtain may be
hung.
I have shown elastic woven wire fabric connected to my side-rails which work
in connection with my intermediately hinged side-rails but it is not essential
to have said web as it may be replaced by any other suitable material.

Improvements in Iron Folding Bedsteads.
I, JAMES MONTGOMERY, of 600, Mildred Avenue, Chicago, in the County of
Cook and State of Illinois, United States of America, Machinist, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
Referring to the drawings filed with my Provisional Specification:-
Figure 1 shows my improved folding bedstead in side elevation.
Figure 2 shows Figure 1 when folded.

Figure 3 shows the head of my said bedstead, partly in section, to show the
operating mechanism of the canopy.
Figure 4 shows the jointed leg of the foot-end of the bedstead, as seen from
the inside in looking from the head end.
Figure 5 shows a side rail with a part of its woven wire mattress, or spring,
and its transverse supports, in plan view.
Figure 6 shows a transverse bar with its coiled supporting springs, the woven
fabric above it, and the chains which connect the supporting bar and woven
fabric.
Figure 7 shows a modification of the joint in the side rail in side view.
Figure 8 shows Figure 7 in plan view.
Like reference letters denote like parts throughout.
The obiect of my invention is to provide an iron folding bedstead having a
woven wire mattress.
To attain said desirable end I construct my said new bedstead in substantially
the following manner, namely:-The tubular posts a have the usual T-shaped
pipe-fixtures a¹ into which are screwed pipe-pieces d into which slide pipes or
rods e secured in elbows f provided with legs g which are connected by a cross-
rod and inside of the parts d, e, f, is the side-rail pivoted at f' to the elbow f
and hinge-jointed at 7 and between the parts 7 and f.
The foot-end posts have their T-shaped fixtures to which the rails bare
attached. Said fixtures have each a hole with a slot h h into which slip the
upper ends of the legs h secured by a pin i on which said leg turns.

page_text: To the transverse leg-connecting rods jis attached a rod k and to the
inner rode or any of the moving parts f, f, g, is attached a cord n passing under
the pin thence up through the post a and out over a pulley o near the top of the
post and to a canopy m hinged at m³.
Cross-bars & connected to the sidebars 6 hold the woven wire fabric w on springs u.
The fabric to is held down near the bars by chains v or equivalent mechanism,
and the fabric is attached directly to one of the bars near the joint c, as shown
in Figure 2, where the springs wo are not in use, which holds the fabric down and
from stretching directly across from end to end, thus enabling a single person to
extend the bedstead and sufliciently stretch the woven fabric for use, a feat
otherwise impossible when the web reaches directly from head end to foot end
as any such tension would tend to raise the head end of the bedstead.
In Figures 7 and 8 cc shows another form of hinge joint in rail b. The web w
must have sufficient tension to make it useful, this is attained by my hinge-
jointed and pivotted side-rails fulcrumed at the reciprocable intermediate supports
at f, thereby forming a toggle-joint of great power.
The bedstead is folded by raising the foot-end which depresses and opens the
joints at c and shortens the space between a and g whereby the rod & brings the
legs inward and parallel to the bars b. Said inward motion of the legs
slackens the cord and thus allows the canopy m to move from its elevated posi-
tion, shown in broken lines, to the position shown in full lines in Figures 2
and 3. Said canopy is here shown as a wire or rod to which a curtain may be
hung.
I have shown elastic woven wire fabric connected to the head and foot enda
of my bedstead to work in connection with my intermediately hinged side-rails
but it is not essential to use said web as it may be replaced by any other suitable
material.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination with head and foot-ends and intermediately hinged side-
rails pivoted to said ends, of reciprocable supports pivoted to said side-rails
between said ends, and means to hold said intermediate support erect, substantially
as specified.
2. The combination with the head and foot ends and intermediately hinged
side-rails, connecting said ends, and reciprocable supports pivoted to said rails
between said ends, of a hinge-operated canopy and cord connecting said canopy
and said reciprocable supports, substantially as specified.
3. The combination with the head and foot-ends and intermediately hinged
side-rails, connecting said ends, and intermediate reciprocable support for said
rails, of a woven web held at the ends of said rails, and a bar connecting said
rails and holding said web to said rails near the hinges of said rails, substantially
as specified.
4. The combination with a reciprocable intermediate leg-support, of jointed
foot-end supports connected to said reciprocable leg-support to reciprocate said
foot-end supports, substantially as specified.
