COMPLETE SPECIFICATION.
An Improved Holder for Sliding Sash Windows.
I, HERMANN RICHTER, of Boizenburg-on-the-Elbe, in the Empire of Germany,
Manufacturer, 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 a means of retaining sliding sash
windows at any height to which it is desired that the window should be opened,
and of releasing such windows when it is desired to open them to their fullest
extent, and is particularly applicable to the windows of railway, tramway, and other
carriages, ships' saloons, and the like.
A sliding sash window holder according to this invention consists of a spring bolt
provided in the door frame or casement in which the window slides, and taking into
recesses suitably provided in the window frame.
In the drawings hereto annexed,
Figure 1 illustrates my invention applied to the window of a railway carriage
door. Figure 2 shews the door and window in vertical section, and Figures 3 and 4
illustrate the locking bolt, drawn to a larger scale.
The window A with its sash B slides in the stile C of the door frame or casement
in the usual manner, the sash B being provided in one or both of its side members
with recesses or notches e arranged one above the other, and into these notches the
projections of the spring locking bolt catches. The locking bar d projects upon
both sides of the carriage door or casement, and is thus capable of being operated
from either side, namely by a pulling action upon one side and a pushing action
upon the other.
A spiral spring h serves to keep the projections of locking bolt
engaged with the recesses e of the window frame. A handle g is provided upon the
sash B, by which it may be raised and lowered.
In operation, the window is raised to any desired height by the handle g. The
projections of the locking bolt d is then allowed to engage with a notch or recess e,
and is kept engaged therewith by the action of the spring h. When it is desired to
release the window, the spring bolt d is pressed upon from the outside, or pulled
from the inside, of the door. This action withdraws the projections from the
recesse with which it has been engaged, and the window sash is free to descend.
Upon raising the window, the projections will engage with each succeeding
recess e, and the window may be retained thereby at any desired height.
By the use of this invention, the employment of leathern straps hitherto used for
the purpose of raising, lowering, and holding sliding sash windows, is obviated ;
the opening and closing of the window may be effected from outside or inside the
apartment with equal facility, thereby providing for this being done by railway
servants and others without the necessity of intruding inside the apartment; and
the window may be released by persons sitting next it (in the case of a railway
carriage and the like) without their rising from their seat.
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 1
claim is:
A sliding sash window holder, consisting of the projection s adapted to enter and
engage with recesses provided in the side members of the window sash by means of

page_text: a spring actuated locking bar d capable of being operated—that is, unlocked-from
either side of the door or casement in which the window slides, substantially as
.described.
