other Openings by Bars and the like.
I, ARPAD VON CSÓKA of Budapest in the Empire of Austria Hungary, Lieutenant
Colonel, 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 :-
This invention relates to the protecting of windows and similar openings by means
of bars or the like, and the improvements have for their purpose to render such bars
easily removable when desired by the occupants of the house or other authorized
persons as for instance in cases of fire or other emergency.
The accompanying drawings illustrate the improved bars and mechanism in
connection therewith.
Fig. 1 being a front elevation of a window provided therewith.
Fig. 2 a cross section thereof on line A B.
Fig. 3 a plan view from below and
Fig. 4 a section on line C D Fig. 1. The bars 6 b... are contrived in two sets, the
upper set connected at their lower ends to the cross bar c' and the lower set con-
nected at their upper ends to the cross bar c¹, meeting the cross bar at or near the
centre of the window. The bars of each set extend respectively upward and downward
from their meeting rails cc and pass through holes in the frame a set in the
masonry, and into tubes h of convenient length above and below the window and
also set in the masonry of the building-The meeting rails c¹ c² are connected by
chains d in the manner shown, passing over pulleys set in small protecting
bearings g on the upper part of the frame a-when therefore the lower bars are drawn
down by handle n'on the rail c³, the upper set of bars are drawn up by the chains d
and the two sets counterbalance each other; the rails c¹ c² engage in the side posts of
the frame a and are guided therein. On each side of the frame is hinged a plate i
covering the whole of the respective side post of the frame, in said plates are arranged
recesses k, and over the bars b of each set slide perforated cross rails cc cc the
ends of which may be brought to such part of the frames a in which their ends are

page_text: guided, that when the said plates i are moved about their pivots 11, the recesses k
may arrive about the rails c c and hold the latter in place-When the bars are to be
withdrawn from across the window, the plates i are folded back and the bars c¹ c²
being now released the two sets of bars may be thrust back into their tubes as before
described and the cross bars c c sliding upon the bars bb... will lie under and over
the respective bars c¹ c² in the lower and upper parts of the frame a. To carry the
loose cross rails cc of the lower set of bars to their places for closing the window,
certain of the bars have small projections at the desired places and as the lower
bars are lifted, the said projections abut respectively against the under side of the
said cross rails and lift the latter to the desired position-Likewise to cause the cross
rails cc of the upper set of bars to arrive in the desired position, pins o o¹ are
arranged in the frame A so that the cross rails c c falling at first in resting contact
with the cross rail c², are arrested by their respective pins at the places they are to
occupy, when the rails c² ² meet; the plates may be folded onto the frame a and
all the bars and cross rails will be held thereby in secure position-The crank
arms m m connected at their ends by bars adapted to be locked together by a padlock
or the like, prevent the opening of the plates ii, therefore of the bars by unauthorized
persons.
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. The combination with a window or other opening of two sets of bars adapted
to be moved toward or from each other, and tubes for reception of said bars as set
forth.
2. The combination of two sets of bars having cross rails c c² ² and chains d,
with frame a having tubes and plates i i, having recesses k k .. . substantially as
and for the purpose set forth..
