page_text: I, KARL BERNHARD of Munich in the Kingdom of Bavaria, Manufacturer, do hereby
declare the nature of this invention, to be as follows:-
The object of this invention is a new or improved device for preventing persons
cleaning windows and others from falling out. The device consists of two parts, one
being formed of two vertical bars connected by a suitable number of tubes arranged
at intervals, and at the top by a breast bar which is bent outwardly at right angles.
In said tubes are guided a corresponding number of rods secured to a third vertical
bar to which is attached above the other half of the breast bar which is displaceable on
the first half by means of a slit. The two outer vertical bars are connected below by
means of two separate foot-boards resting and displaceable by slits and bolts on each
other, with suitable carriers which are introduced with quadrangular bolts into cor-
responding eyes provided inside the window ledge. Thus the improved device can be
adjusted for any breadth of window and reduced to a very small volume when putting
it aside.
To connect the breast-bar safely with the window ledge, displaceable angle pieces
provided at the extremities of the breast-bar are shifted back when introducing the
latter into the inner guiding of the window ledge. Subsequently the angles are placed
with one shank into corresponding recesses of the ledge. The vertical rods being
slightly bent up or having corresponding projections are pressed against the window
ledge by introducing bolts or wedges into slits provided at the ends of the breast bar
thus holding the latter. To increase the safety the said angle pieces have hinged thereto
suitable plates or tongues which are placed with slits over eyes provided on the window-
ledge and fastened thereto by means of bolts or wedges.
The angle-fastening may also be replaced by any other suitable device and the
whole safety contrivance may be secured to the window frame in any other convenient
manner. Also the tube-guiding for the two parts of the device may be replaced by a
suitable rod-
1-or other guiding.

page_text: I, KARL BERNHARD, of Munich, in the Kingdom of Bavaria, Manufacturer, do
hereby declare the nature of this invention, and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement
The safety devices hitherto known for protecting persons cleaning windows or
others, from falling out, are partly not applicable to every kind of window, partly do
not afford the desired safety, for instance those with a protective cloth.
These drawbacks are intended to be obviated by the improved safety contrivance
illustrated by the accompanying drawings, Sheet I and II, in which
Fig. 1 is a vertical section of the improved device.
Fig. 2 a view thereof from the inner side of the window, and
Figs. 3 to 13 represent details.
The improved safety trellis or guard consists of two parts, one of which is formed
of the two vertical bars S S' bent outwardly at the top as shown in Fig. 1 and con-
nected with each other by means of a convenient number of tubes. In the latter aro
guided the rods or thinner tubes of the other part of the window guard, which are
suitably connected with the bar S, likewise bent outwardly. The carrying bars t, t¹
and t, rigidly connected at one end with the bars S2 S₁ and S respectively, extend
with their other extremities beyond the window-ledge and are so connected hinge-
fashion with the bar of a stand or frame a as to allow the bar S2 with the carrying
bar to be easily displaced on the bar a extending beyond the stand as shown in
Fig. 2. The bars t t support a foot board a having at the bottom guidings b of
flat iron or other convenient material for the carrying bars, to admit of its lateral
displacement.
The guard when not being used, is turned inside about the bar and laid over
the stand.
It is understood, that the mechanism referred to for connecting the guard with the
stand may be replaced by any other easily detachable device. The carrying bars may,
for instance, be bent at right angles, as illustrated by Fig. 3, and secured by bolts m,
or thumb screws or otherwise in corresponding apertures provided in the stand.
To allow of a solid support for the vertical bars S, S¹ and S' outside the window,
bolts S³ are provided at their bottom, which are-adjustable by means of screws or
otherwise. The stand, if higher than the window ledge, for instance as high as indicated
by line L L, Fig. 1, may be secured by means of a bolt or in any other suitable manner
to the floor, in order to provide a reliable support for the safety device.
The mode, shewn in Fig. 4, of securing the guard to the window ledge by means of
a screw is particularly adapted for shop windows, where no hooks are provided for
suspending the guard.
The upper or breast bar is telescopically arranged like the other cross pieces, and
to its extremities are secured hinge-fashion at the correspondingly bent arms

page_text: extending inwardly and carrying the devices for fastening the guard to the window
ledge at the top. The arms being revolvable, the whole device is more handy and
capable of being reduced by folding to a small compass. Said fastening devices may
be inade in various manners, for instance as illustrated by Figs. 5, 6 and 7 in horizontal
section, vertical section and external view respectively.
One side of the angle piece l', which is displaceable on the bent extremity of 1, is
provided with a leaf spring and is introduced into a corresponding recess of the
window ledge, in which it is secured by means of a projection provided on said
spring. To afford additional safety, a hook q, which is lodged in the eye 9² provided
on the ledge is revolvably attached at q' to the angle piece ¹³.
The spring alone however, Figs. 12 and 13, or the hook and eye alone, Figs. 8 and 9,
ensure a sufficiently safe fastening.
In the construction shown by Fig. 10, the arın is provided at its free extremity
with a slit, by means of which it is placed over the bolt v and secured with a pin passed
through the eyelet-hole v².
Or a thumb screw is employed as shewn in Fig. 11.
To render the device completely safe at the pivot lo, a tube w, Fig. 8 may be shifted
over the hinge, or a leaf spring z Fig. 10 secured on may be used, the nozzle z¹ of
which engages at the proper moment with a suitable indent provided in the
breast bar.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1) protective trellise or guard for windows, which is rendered adjustable for any
breadth of window by means of a telescopic combination of tubes, or of tubes and
rods, substantially as illustrated and described.
2) In window guards, the combination, with horizontal tubes connected by means
of bars S S¹, of rods or thinner tubes h secured to a bar S2 and displaceable in said
tubes, substantially as and for the purpose set forth.
3) In the window guard referred to in claim 1), the combination with the bars
carrying the safety device, of a stand or frame a a foot board a and guides & substantially
as and for the purpose set forth.
4) In the window guard referred to in claim 1), the application of a screw for
securing the same to the window ledge, substantially as set forth.
5) In the window guard referred to in claim 1) the application of adjustable boli S³
substantially as and for the purpose set forth.
6) In the window guard referred to in claim 1), the combination, with the breast
bar, of arms and of the devices described for securing the latter to the window ledge,
substantially as and for the purpose set forth.
