I, HENRY LIVERSIDGE, Junior, of Driffield House, in the City and County of York,
Merchant, do hereby declare the nature of this invention to be as follows:-
Hitherto, market places have either been open, when they have been subject
to the effects of inclement weather; or they have been covered with a roof, which is
unslightly and inconvenient when not required for use.
The object of this invention, is to provide a roof for covering market places and the
like, which may be readily erected when required, and which when not in use may be
folded away and placed out of sight, leaving the said market place a free and open
space.
.
According to my invention, I form a series of troughs across the pavement of the
market place, the said troughs being parallel to each other and being covered with
flaps. Within the troughs at suitable distances apart, I provide pillars, which are
hinged in the framework of the troughs in such a manner that they may be turned
on their pivots and placed on end in a vertical position. Below each pair of pillars,
a folded section of roof is situated, the ends of the section being provided with
projecting studs which slide in grooves situated in the sides of the pillars. An end-
less cord or chain, runs over suitable pulleys and is attached to the studs, in such a
manner that the section may be hoisted simultaneously up the column at an equal
speed on both sides, and when the section is in position at the top of the said column
the studs are turned, thus locking the section in position, As the section rises it
unfolds, and arms or supports which are situated in the pillars rise by reason of the
movement of the chain and hold the flaps of the section at the required angle.
These sections with their pairs of pillars, are erected in lines along the troughs, and
as they are in parallel rows the lower edges of the flaps are near to or in contact with
each other when the roof is erected, and by placing gutters at the edges of the flaps,
rain water may be led away to a suitable outlet.
It will thus be seen that the roof above described may be erected in a very short space.
of time, and when the said roof is not required, it may be folded up and placed in the
troughs, where it is covered over by the flaps, which leave the market place or other
open space perfectly free and open to the air.

Market Places, and other similar Open Spaces."
I, HENRY LIVERSIDGE, Junior, of Driffield House, in the City and County of York,
Merchant, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
Hitherto, market places have either been open, when they have been subject to
the effects of inclement weather; or they have been covered with a roof, which is
unsightly and inconvenient when not required for use.
The object of this invention, is to provide a roof for covering market places and
the like, which may be readily erected when required, and which when not in use
may be folded away and placed out of sight, leaving the said market place a free and
open space.
According to my invention, I form the structure in sections, each section being
composed of a folding roof situated between a pair of hinged pillars, and the folding
roof, pillars and parts connected therewith are contained within parallel troughs in
such a manner that the sections may be raised one after the other so as to form a
continuous roof or structure, and when the said structure is not in use, the sections
may be lowered into their troughs, and the upper part of the troughs being covered
with hinged flaps, the market place is again converted into a free and open space.
In order to illustrate my invention, I have shewn in the accompanying drawings
one section of the structure, and the various parts of same are indicated by similar
letters of reference in all the figures.
Figure 1 is a sectional side elevation and Figure 2 is a transverse section, of the
apparatus in the folded position.
Figure 3 is a sectional side elevation of the apparatus in the raised position, and
Figure 4 is an end view of same.
A is the trough for containing a row of the sections of the structure, and B, are
flaps for covering in the troughs A. C, C are end pillars which are fixed firmly in
position by means of brackets C₁ at their base and girders C2 at their upper euds.
The pillars C are formed with grooves C³ on their interior faces, and cross pieces c
are attached to the backs of same. D, D are hinged pillars having grooves D3 D³ in
same which are mounted on axles E, E, and the said axles E, E are carried in
bearings E¹, E¹, which being set slightly out of line allow the pillars D, D, to be
hinged down side by side as seen at Figures 1, and 2, without coming into contact
with each other.
DI, D¹ are counterbalance weights which are situated on the lower extremities of
the pillars D, D, and D², D² are catches which engage with the cross pieces C4 when
the pillars D are brought into the upright position. F, F is a folding roof, which is
hinged at G, G on sliding blocks H, H. J, J are links which are jointed at one end
to the interior sides of the roof F, F, the opposite ends of the links F, F, being
jointed to blocks K, K which slide in the grooves C³, C3, and L is an inverted channel
for covering the joint between the two portions of roof F, F. M, M and M', M' are
pulleys situated on the ends of the pillars D, D, and N, N are two pairs of pulleys
which are situated at the base of the fixed pillars C, C.
P, P are a pair of pulleys which are mounted in line with one of each of the
pulleys N, N, and R, R are a pair of pulleys which are mounted in line with the
other pulley of the same pairs of pulleys N, N.
S is a winch having one portion S¹ of a regular diameter, and the other portion S2
of an increasing diameter, and the said winch is actuated through the worm

page_text: wheel, worm S* and spindle S5, which latter may be actuated by a key. T, Tare
ropes which are connected to the blocks H, H and pass over the pulleys M, M and
behind the pulleys M¹, M³, and then descend and pass under the pulleys N, N and
pulleys R, R, from which latter they pass upwards to the portion S¹, of the winch S.
V, V are ropes which are attached to the blocks K, K and pass over the pulleys M, M,
and behind the pulleys M¹, M¹, and descending under the pulleys N, N they pass
to the pulleys P, P from whence they rise to the winch S where they are attached
near the portion S². W is a table which is provided with folding legs W¹, and the
ends of the table are pivoted out of centre at W2, on sliding pieces X. The said
sliding pieces X are made in a hollow form to allow the links J, J to pass through
them when the parts are in the folded position. Y, Y are ropes for connecting the
sliding pieces X, X to the blocks K.
When it is desired to raise the structure from the position shewn at Figures 1 and 2,
to the position for use as seen at Figures 3 and 4, the flaps B are hinged back so as
to uncover the trough A, thus exposing the mechanism above described. The
pillars D, D are then raised into the upright position, the weights D1, D¹ enabling
this to be done with ease, and when the said pillars D, D are quite erect, the
catches D2, D2 engage with the cross pieces C and firmly lock the pillars in the
upright position. The spindle S5 is now rotated, thereby turning the worm S', worm
wheel S3 and the winch S, and the turning of the winch S has the effect of winding
in the ropes V, V and T, T. The movement of the ropes V, V and T, T hoists the
roof F, F, the blocks H, H and K, K sliding in the grooves C³, C³, and D³, D³, and
this upward movement is effected with the roof F, F in the closed position until the
said roof is clear of the ground, when the ropes V, V coming to the portion S² of the
winch S wind with increased speed, and cause the blocks K, K to rise with greater
speed than that of the blocks H, H. This increase in speed of the blocks K, K
causes the links J, J to open out the roof F, F, until when the blocks H, H arrive at
the top of the pillars D, D the roof F, F, is opened out widely as seen at
Figures 3 and 4. The movements of the blocks K, K pull the ropes Y, Y and thus
raise the sliding pieces X, X, and the table W being lifted from the trough A turns
on its centre to a horizontal position by reason of its being mounted out of centre.
The flaps are now folded back, and the legs W₁ of the table W being folded down,
the structure and table are ready for use.
The above description illustrates how a single section is raised from its position in
the trough, and the following sections are afterwards raised in a similar manner;
and it will be readily seen that by forming the troughs in parallel rows, the sides of
the roofs of one row of sections may be brought adjacent to the sides of the roofs of
the next row of sections. Gutters can be provided for the purpose of carrying
off the rain, and the joints between the sections may be filled in by hinged leaves or
connecting pieces.
When the structure or section is not required for use, it is readily lowered again
into the trough A, which latter is then covered by the flaps B, as shewn at
Figures 1 and 2.
The roofs F, F may be made with double folds, which may be opened by lazy
tongs, thus enabling a larger roof to be obtained whilst employing a more shallow
trough.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is- to be performed, I declare that what I
claim is:
1. A structure for covering market places and other similar open spaces, consisting
of two hinged pillars mounted in a trough, a hinged roof sliding on the pillars, and
suitable means for raising the said hinged roof, substantially as and for the purposes
set forth.
2. The combination of the pillars C, C, hinged pillars D, D mounted on axles E, E,
counterbalance weights D¹, D¹, and the folding roof F, F, substantially as and for the
purposes set forth.
