COMPLETE SPECIFICATION.
Improvements in the Construction of Windows, Doors, Gates,
Shutters, and the like for Tightly Closing same.
I, CARL SUMMERMANN of 6, Furstenbergstrasse, Munster, Westphalia in the
Empire of Germany, 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 has for its object to provide horizontally movable windows, doors,
gates, shutters or the like which according to my invention are capable of shutting
and remaining air-tight and rain-tight-or practically air and rain tight-when
closed which object has not usually been effected in doors windows etc. as heretofore
constructed.
This object is effected according to my present invention by constructing the
window door etc. to travel in a lateral direction and raising or depressing the
window door etc. shortly before its end position and moving it sideways and also
either outwardly or inwardly.
Referring to the accompanying drawings
Fig. A shows (on an enlarged scale) vertical sectional views upon the line ef
Fig D-showing the window etc. just before closure at ef and closed at e ƒ¹.
Fig. B shows similar views on line ef Fig. D but with different shaped parts
at the point or points of closure.
Figs. C and C¹ are cross sectional views (on an enlarged scale) upon the line c d
Fig. D-showing the side edges of window door etc. just before closure at Fig. C
and closed at Fig. C'.
Fig. D is a view in elevation of a window arranged constructed and closed
according to my present invention.
Fig. E is a vertical sectional edge view on line ef Fig. D.
Rollers, balls or grooved wheels etc. may be employed as supporting parts for
the door.etc. A guide rail a is provided for the said grooved wheels etc. to travel
on and may be situated below or above the window door etc. The latter when being
moved into the open or the closed position travels freely and easily advantageously
without touching or friction against the fixed parts of the enclosing or surrounding
framing.
But immediately before reaching the end position (i.e. the position of closure)
the window etc. is simultaneously raised (as in Fig. A of the drawings hereunto
annexed) or depressed (as in Fig. B) and moved also either towards the outside or
towards the inside see the respective closed positions in Figs. A B and C¹.
The movement of the window etc. is effected by the following means:-
The window is depressed or raised by means of a curve or curves recesses or
projections respectively in or on the guide rail and in or upon which is adapted
to travel the grooved wheel y carried in the supporting arm z which latter at its
lower end supports and carries the window door etc. v.
By means of this upward or downward movement thus imparted to the
window etc. v the upper and lower faces or edges or both of the window etc. (see
the end position in Figs. A and B) are pressed tightly against the fixed or
stationary framing of the aperture for the window door etc.-which are formed of
a special shape to fit closely in or on corresponding shaped parts on the window
door etc.
In a similar manner also the vertical sides or edges of the window door etc. are
caused by the lateral movement of the latter to close tightly against the fixed
framing and to remain tightly closed

page_text: The third movement of the window etc. which takes place immediately before
the end position simultaneously with the afore-described movements takes place in
the outward or in the inward direction according as it is desired that the window etc.
should be pressed with its outer or with its inner surface against the fixed framing
(see the closed positions in Figs. A B and C¹).
IC
This movement is effected by the guide rail being bent outwardly or inwardly at
the places where the supporting parts y of the window etc. are situated in the
closed position see sectional views ef¹ Figs. A and B. The window etc. is thus
carried towards the outside or towards the inside by this device and bears around
its frame against the outer or inner surface of the fixed framing..
The contact surfaces of the faces or edges of the window sash door etc. and of
the fixed framing may be bevelled in accordance with the inclined movement
which the plate receives as it reaches the end position so that the same engage
with each other in claw-fashion see Figs. C and C¹ or may be formed in any other
suitable manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The arrangement and combination with windows, doors, gates shutters, etc. of
suitably shaped guiding parts and a guide rail so shaped and formed as to cause
the said window etc. while moving laterally just before reaching the end position to
move simultaneously up or down as well as in an outward or inward direction
whereby the suitably shaped closing faces or edges of the window etc. and also the
outer or inner surfaces of the same are pressed tightly against the fixed framing
substantially in the manner and for the purposes hereinbefore set forth.
