PROVISIONAL SPECIFICATION.
Improvements in and relating to Collapsible Frames for Gates,
Shutters, and like uses.
I, WILLIAM HAROLD MARSHALL, of 151 Tulse Hill, County of Surrey, Art
Metal Worker, do hereby declare the nature of this invention to be as
follows:-
'This invention has for object certain improvements in and relating to collapsible
frames for gates, shutters, and like uses.
For the purpose of my invention, I prepare, say, three uprights, to one of these
I attach links, rods, or bars at desired distances apart said links, rods or bars being
slotted to ride upon pins of the other two uprights or provided to ride in slots or
apertures of lumps swivelled to the other two uprights. The third bar of the
foregoing may serve also as the first upright of the second frame, thus any number
of such frames can be united and they can be collapsed for reducing the width of
opening or uncovering the body which they previously closed or protected.
The uprights or some of them can be supported by horizontal bars which may
be fixtures, or certain parts of such horizontal bars may be removeable or foldable
to be clear of the openings when the frame or frames is or are collapsed.
The invention is specially adapted for lifts and passage openings, for shop
grating shutters, also for doorways and entrances generally.

Improvements in and relating to Collapsible Frames for Gates,
Shutters, and like uses.
I, WILLIAM HAROLD MARSHALL, of 151 Tulse Hill, County of Surrey, Art
Metal Worker do hereby declare the nature of my said 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 has, for object certain improvements in and relating to collapsible
frames for gates, shutters, and like uses.
For the purpose of my invention I prepare, say three uprights; to one of these
1 attach links, rods, or bars at desired distances apart, said links, rods, or bars
being slotted to ride upon pins of the other two uprights, or provided to ride in
slots or apertures of lumps swivelled to the other two uprights.
The third bar of the foregoing may serve also as the first upright of the second
frame, thus any number of such frames can be united, and they can be collapsed
for reducing the width of opening or uncovering the body which they previously
closed or protected.
The uprights or some of them can be supported by horizontal bars which may
be fixtures, or certain parts of such horizontal bars may be removeable or foldable
to be clear of the openings when the frame or frames is or are collapsed.

page_text: The invention is specially adapted for lifts and passage openings, for shops,
gratings, shutters, also for doorways and entrances generally.
My invention will be clearly understood by reference to the annexed drawings
in which at Figure 1, I show a frame adaptable for a gate or shutter in an open
condition, or such as when covering the entrance to a lift opening, a shop, or an
entry. Figure 2 represents the same in a collapsed condition.
Figures 3 and 4 are end or edge views of a single and of a double linked
arrangement of frame with slotted links.
Figures 5, 6, 7, 8' are similar views of a frame in which swivelled rods are
arranged to turn or pivot on axle pins with lumps, and to slide through or within
other lumps forming part of the pivot pins. Figures 9 and 10 are detached
elevations of one of the link rods with lump and axle pins. Figures 11 and 12
are elevations of a collapsible gate with means of securing it in an opened out
condition.
According to Figures 1, 2, 3, and 4, each bar A is composed of two strips
secured at the desired distance apart by shouldered pins or rivets B, B, some of
which also serve as axles for the travelling rollers C, C, and others as pivots for.
the slotted links D, D, to swivel on or as guides for the slotted portions of the
links to slide on. If rods be fitted they have lumps D' as pivots and slide through
other lumps of the adjoining uprights.
The end uprights E, E, (only one of which is shown) are provided with socket
eyes or shoes F, F, to slide upon rails G, G. The free uprights A, A, run upon
the bottom rail by their rollers C but the top ends are supported from an
additional rail H, which according to Figures 11 and 12 is dispensed with, the
rollers C running upon the rails G, G, to carry the bars A, A, along for both
opening and for closing the passage.
The rails G, G, may be each in a single piece, or they can be hinged to fold, as
indicated at Figures 11 and 12 where I have shown a collapsible gate fitted in
position. To prevent the upper rail dropping, or of the uprights A being pushed
along when the gate is closed and secured, affix an additional strip I to the end
upright E for the fastening padlock to engage and fix it.
I am aware that collapsible frames suitable for gates, shutters, and similar
purposes, or uses have been already devised and employed, I therefore make no
claim to the general construction or application of such for the purposes, but
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The arrangement of links shown on the annexed drawings, said links being
pivoted and slidable in or upon pins, rivets, or swivels of uprights three of such
uprights with their links constituting a frame of which any number can be
associated in the manner described to form a collapsible gate, shutter, or the like,
as set forth.
2. The construction of collapsible gate, shutter, and like frames in distinct
sections capable of being increased in number to form a gate, shutter, or the like
as and in the manner described and substantially as represented by the annexed
drawings.
3. The combination of uprights, rollers, supporting bars and guide bars when
arranged in the manner and for the purpose or purposes explained.
