COMPLETE SPECIFICATION.
Folding Gate.
We, CHARLES BAYER, Manufacturer of Wrought Iron Wares and PAUL
SCHERBNER, Mauufacturer of Wrought Iron Wares, both of 449 to 455 West
41st Street in the City of New York, in the County of New York, in the State of
New York, in the United States of America, 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 :-
The object of our invention is to provide a new and improved folding gate
which occupies very little space when folded, is light, strong and durable and can
easily be manipulated.
In the accompanying drawings forming a part of this Specification, and in which
like letters of reference indicate like parts in all the figures:
Figure 1 is an elevation of our improved gate opened.
Figure 2 is a similar view closed.
Figure 3 is an enlarged detail vertical transverse sectional view, parts being
broken away.
The main gate bars M are arranged in pairs, and may be plain iron bars of the
required thickness or may be provided with strengthening beads or ribs as may be
desired and their upper ends may be rounded off or finished in any other suitable
manner. The bars M of each pair are so arranged that one is exactly behind the
other looking from front to rear and the pairs of bars are suitably spaced so as to
divide the space to be closed by the gate into a number of uniform fields by said
bars, as appears in Figure 1.
The bars M are connected in each field by a pair of pivoted links N, both at the
top and bottom, the inner ends of the links of each pair being pivoted to each
other and the outer ends of the links pivoted to the bars M, said pivoted links
serving to stiffen the gate when open and to brace and support each pair of bars M
from and by the adjacent pair.
The bars M are furthermore connected at the top and bottom and if desired, at
the centre also, by a series of levers O arranged between the bars M of each
pair, the levers O crossing each other and having their ends pivoted to each other
to form lazy tongs, and said levers O are pivoted to each other and to the bars M
at the intersections of said levers O.
Intermediate bars P connect the top and bottom lazy tongs formed by the
levers O.
For the purpose of keeping the bars M parallel two intermediate bars Pare
arranged in each field, of which one connects the lower joints of the upper and
lower lazy tongs and the other the upper joints of the upper and lower lazy
tongs the two bars P resting flat on each other so that one can slide up and the
other down.
A collar R is secure to each bar P of each pair, one at the top and the other at
the bottom so as to hold the said bars P of each pair in place and to guide them
while sliding on each other.
It is not necessary that double bars P be arranged in each field as shown, as it
is sufficient if they are provided in some fields only, but we prefer to provide them
5 in all fields.
In the open position of the gate as shown in Figure 1 the pairs of bars M are
separated a uniform distance, the bars P are midway between them and the links N
form obtuse angles and the lazy tongs are opened.

page_text: When the gate is closed as shown in Figure 2 the bars M are in contact and the
bars P and the folded lazy tongs levers O are folded between the bars M in
direction from front to rear as are also the links N. The bars M are made quite
heavy for strength and resisting power, but can be spaced quite a distance apart,
so as to reduce the weight of the gate, as the spaces between are subdivided by the
lighter intermediate bars P.
As the several bars M and P at all times remain parallel and can not be
brought out of their parallelism, even under the greatest strain, the gate can
readily be opened and closed, without binding, by applying power at the top, middle
or bottom.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we. declare that what we
claim is :
1. In a folding gate the combination with a series of vertical bars, of pivoted
folding links connecting them at the top and bottom, lazy tongs connecting said bars
at the top and bottom and intermediary bars between the above mentioned bars
and connecting the top and bottom lazy tongs, substantially as herein shown and
described.
2. In a folding gate, the combination with a series of vertical bars, of lazy tongs
connecting them at the top and bottom, intermediate vertical bars between the
above mentioned vertical bars and connecting the top and bottom lazy tongs
substantially as herein shown and described.
3. In a folding gate, the combination with a series of vertical bars of lazy tongs
connecting them at the top and bottom of intermediate bars, in pairs between the
above mentioned vertical bars of which intermediate bars one of each pair
connects the upper joints of the upper and lower lazy tongs and the other the
lower joints and collars on said intermediate bars, substantially as herein shown
and described.
