COMPLETE SPECIFICATION.
New and Improved Means of Securing Panes to the Window-frame
for Preventing the Frame-wood from becoming Rotten.
I, FRIEDRICH SAGEBIEL, of Linse near Bodenwerder on the Weser, in the
Kingdom of Prussia, Germany, Technologist, 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 ordinary method for securing panes to the window-frame consisted in the
covering of the pane with putty, after it had been inserted into the frame. The
accompanying drawing gives an illustration of this method,
Fig. 1 being a vertical section through the lower horizontal part of the frame.
(a) is the frame, (b) the pane, (c) the putty. In applying this method, the
disadvantage is felt, that the putty will very soon become incoherent, whereafter
the moisture adhering to the pane will flow down at both sides and be gathered in
the incision (d), from where not being able to escape it is drawn into the wood.
After this occurrence has repeated itself several times, the frame begins to become
rotten in consequence and the disagreeable experience is made, that the lower part
has become thoroughly rotten, while the other part of the frame has remained
entirely unimpaired.
The present invention is destined to remove this disadvantage. As may be seen
from Fig. 2, a vertical section through the part corresponding with Fig. 1, the
applying of putty to the pane (6) is dispensed with so that the water gathering on
the surface of the pane may run down till it reaches the lower edge (e). This
edge (e) lies completely exposed, as the frame (a) does not join the pane without
interruption till it reaches the lower edge, but forms an exposed curve (ƒ),
surrounding the lower edge and further assumes an oblique direction (g) at its
lower part. The water dropping down from (e), flows down the sloped part (g)
and from there downward, without penetrating the wood.
The securing of the pane (b) to the frame (a) is effected from the interior part
by a watertight layer of putty (c), the action of which is rendered more effective
by providing a recess (i) in the frame (a), which is completely filled up with putty,
so that no water is able to penetrate at this place. The adhesion of the pane to
the layer of putty is further supported by a few nails, screws or hooks (k), catching
hold of the pane (6) and driven sufficiently far into the frame-wood, to exclude the
pane from becoming loose.
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 new and improved means for securing panes to window-frames for preventing
the frame-wood from becoming rotten consisting in joining the pane (b) to the
frame-wood (a) in such a manner, that it remains completely exposed at the outer
side and the frame does not come into contact with the lower edge (e) of the frame-
wood, the latter being formed at the lower part to a curve (f), surrounding the
lower edge (e) and passing into a sloped part (9) permitting the water to flow off,
while at the same time the pane (6) is puttied watertight to the frame-wood from
the interior part by providing the frame with a recess (i) to be filled up with

page_text: putty, while the loosening of the pane (b) from the frame-wood (a) is prevented by
nails or screws (k) to be driven into the latter.
