INUYIDIONAL OF MULTICATION,
Improvements in Folding Gates, Doors, or Shutters for the Roiling
Stock of Railways or Tramways, and for other purposes.
I, DENIS DOYEN, of No. 14 Rue de la Gouttière, Brussels, Belgium, do hereby
declare the nature of this invention to be as follows
My invention relates to a construction of folding gates or doors more particularly
applicable to the platforms and doorways of the rolling stock of railways or tram-
ways, but also applicable to buildings whether as doors, gates or shutters.
I constinct such gates on doors of vertical bars that are connected together by
diagonal bars pivotted thereto, so that on opening the door or gate the vertical
bars are brought together and for closing them they are moved apart, the diagonal
bais being respectively pivotted at one end to the one vertical bar, while the pivot
of the other end slides up and down in or on a guide on the other bar.
According to one arrangement for this purpose I provide, in addition to the
diagonal connecting bais, either at the upper or the lower end, or at both, a
horizontal rod or bai connected nt one end to the vertical bar that slides to and
fro, and sliding at its other end in a socket in the door post on the other side of the
door opening, so as to guide aud support the moving bar in its parallel motion in
opening and closing. Such horizontal iod may also serve as the means of locking
the gate or door in the closed position, by forming a lateral hole or notch in the
rod or bar, near its inner end, into which takes the sliding bolt or spring catch of
any suitable locking device.
According to another modification I employ in place of the horizontal sliding rod
or bar, a bar that is hinge-jointed in the middle of its length, and connected at
each end to one of the sliding bais, so that when the door is opened, the two halves
fold together like a toggle link.
This arrangement can also be locked in the closed position, by providing the
jointed bar with a tail end which, when the door is closed, is held by a catch or
bolt that prevents the bat fiom folding together.
According to another consti uction the horizontal sliding or jointed bar is dispensed
with, and the locking of the door or gate is effected by providing at the upper or
lower part of the door frame a horizontal toothed nach or notched bai, while the
moving vertical bar has a vertically sliding spring catch, that springs into the
spaces or notches of the tack or notched bai, and thus holds the door in whatever
position it is moved into When in the closed position, the sliding bolt or catch is
locked by a suitable locking device so as to be prevented from being withdrawn
fiom the notob.
With the said vertical locking bolt or catch taking into the top or bottom rack
may be combined a horizontal spring catch at the side of the vertical sliding
bar, that catches onto a stud at the side of the door frame, the vertical catch being
pivotted to the horizontal one, so that both are moved together and locked by one
and the saine lock, which may be made changeable, for security.
In all the above described constructions of doors or gates theic may either be a
single set of the pivotted diagonal connecting bars, or there may be two or more
sets pivottod together like a lazy tongs, or there may be one or more intermediate
vertical bars in the width of the door or gate, with a set of the pivotted diagonal
bars between each two. Such gates or doors may be entirely closed in, instead of
baving openings between the bars, by fixing to the inside or outside thereof covering

Improvements in Folding Gates, Doors, or Shutters for the Rolling
Stock of Railways or Tramways, and for other purposes.
I, DENIS DOYEN, of No. 14 Rue de la Gouttière, Brussels, Belgium, do hereby
declate 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:
My invention relates to a construction of folding gates on doors more particularly
applicable to the platforms and doorways of the rolling stock of railways or tram-
ways, but also applicable to buildings whether as doors, gates or shutters.
construct such gates or doors of vertical bars that are connected together by
diagonal bars pivotted thereto, so that on opening the gate or door the vertical bars
are brought nearer together, and in closing them they are moved farther apart,
each diagonal bat being at one end pivotted to one of the vertical bais, and having
a pivot at its other end sliding up and down a guide on the other vertical bar.
I shall describe several modified auangements of the bars referring to the
accompanying diawings
Fig. 1 shews in elevation a gate according to my invention closed, Fig. 2 shews
it open,
Fig 3 is a plan of Fig. 1.
Fig. 4 shows a gate with jointed cross bais closed, and Fig. 5 shews it open.
Fig. 6 is a plan of Fig. 4.
Fig. 7 is an elevation and Fig 8 a plan of a double gate, Fig. 9 being a plan
shewing it open.
Fig. 10 is a sectional plan to an enlarged scale of one of the slides for the ends
of the diagonals.
Fig. 11 is an elevation as seen from the inside of a waggon door closed, Fig. 12
shews it open.
Fig. 13 is a plan on A B and Fig. 14 a plan on C D,
Fig. 15 shews to an enlarged scale a modified form of safety catch.
Referring to Figs. 1, 2 and 3, A is a fixed tube in which slides the upper bai B
of the gate, C is an upright attached at the top to A and having a foot D fixed on
the base A'. C 18 another upright attached at the top to B and connected to C
by two diagonals F and G pivotted at J J to the uprights and to one another at H,
also having mounted on the lower ends tolleis K which can roll up and down
within the hollows L (Fig. 10) of the uprights C C¹.
At the end of the bar B are two buttons or handles M M' for closing and opening
the gate. On the gate post X are two flauged pieces which partly embrace
the upright C¹ when the gate is closed.
When the gate is opened the rollers K ran down the uprights to the points P Pl
(Fig. 2) the diagonals F and G turning on their pivots while the uplight C¹ is
brought close to C.
For a wide gate two pairs of diagonals may be employed as indicated by the
dotted lines in Fig. 1.
There may also be a lower bar a sliding in a tube at A'.
For securing the gate when it is closed a spring N is fixed ou A and provided
with a bolt that enters a hole R in B, holding it until the bolt is withdrawn.

page_text: By providing other holes in B for the bolt the gate may be held open or
partly open. A lock may obviously be substituted for the spring bolt.
As shewn in Figs. 4, 5 and 6 the upper bar is made in two parts B B¹ jointed
together; and there may be a similar bar bb below as indicated by the dotted
lines in Fig. 4.
Figs. 7 and 8 shew two gate leaves cach like that in Fig. 1 the one arranged so
that its diagonals F, G slide behind those of the other when opened by hand applied
to the handle O¹ so as to open as far as the vertical dotted lines in Fig. 7. the
middle upright C, which is double, and the two uprights C and C¹ then occupying
the position shewn in Fig. 9.
As shewn in Figs. 11, 12, 13 and 14 which represent the gate of a goods waggon,
a spring pawl o engages in any tooth of a fixed ratchet rack r holding the gate
more or less open. As shewn in Figs. 11 and 15 the pawl can be disengaged by
depressing the handle Y which at the same time, by pushing down the latch S, in
opposition to the spring T disengages it from a fixed stud Z.
Instead of thus disengaging the latch, it may be depressed by a key inserted
at S' on the other side of the gate.
Fig. 13 shews the gate closed and also the outer door U slid over it, Figs. 12
and 14 shew the gate open and the outer door slid back.
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
clann 16-
1. A folding gate having its upper bar sliding in a fixed tube and its vertical
bais connected by pivotted diagonals, substantially as described with reference to
Figs. 1, 2, 3, and 10.
2. A folding gate having its upper bar made in two parts hinged together
substantially as described with reference to Figs. 4, 5 and 6.
3. A double folding gate arranged so that the diagonals of the one leaf in
opening, slide behind those of the other, substantially as described with reference
to Figs. 7, 8 and 9
4. In combination with a folding gate of the hinds above referred to, a ratchet
rack, spring pawl and lock substantially as described with reference to Figs. 11, 12,
13, 14 and 15.
