Improvements in Window Guards.
I, JULIUS CHRISTAPF MEYER, of 131 East 124th Street, New York, County
and State of New York, United States of America, Gentleman, do hereby declare
the nature of this invention to be as follows :-
This invention relates to a window guard for vertically movable counterbalanced
sashes, which will always fill the opening beneath the lower sash, no matter to
what extent the latter is opened. The guard is placed between the lower edge of
the lower sash and the window frame. It consists of a pair of rods pivotally
secured to the two corners of the sash and adapted to be received by a pair of
tubes which are pivotally secured to the two diagonally opposite corners of the
frame.
It will be seen that by raising and lowering the sash, the rods will be more or
less telescoped by their tubes, so that in this way, the guard will automatically
adapt itself to exactly fill the opening beneath the sash. If the sash is entirely
closed, the guard is received by a groove of the frame.
I prefer to so construct the guard that it may be detached from the sash if
desired. To this effect the rods are not pivoted directly to the sash, but to an
intervening rail. This rail is mortised at its upper edge for the reception of
locking bolts secured to the sash. When the guard is not to be used, the rail is
unlocked from the sash and then the rail together with the folded guard, remains
concealed within the window frame and is entirely out of action. But when the
guard is to be put into operation the rail is locked to the sash, whereupon the
guard will open and close with the sash in the manner already described.
Dated this 6th day of June 1893.

Improvements in Window Guards.
I, JULIUS CHRISTAPF MEYER, of 131 East 124th Street, New York City,
New York, United States of America, Gentleman, 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 a window guard which is placed between the lower sash
and the window frame, and which is so constructed that it will always fill the
opening beneath the sash, no matter to what extent the latter is opened.
In the accompanying drawings
.
Figure 1 is an elevation of a window frame provided with my improved guard
and showing the lower sash lowered.
Figure 2 is an elevation partly in section of the window, with the lower sash
raised.
Figure 3 is a longitudinal section on line x, a, Figure 4, and
Figure 4 a cross section on line y, y, Figure 3.
The letter a, represents a window frame and b, is the lower sash adapted to be
raised or lowered within the frame, as usual.

page_text: Between the lower edge of the sash , and the lower rail a', of the window
frame a, my improved guard is secured. This guard consists of a pair of rods.
pivotally secured to the two corners of the sash b, and adapted to be received by
tubes c', which are pivotally secured to the two diagonally opposite corners of the
rail a¹. It will be seen that by raising and lowering the sash, the rods will be
more or less telescoped by their tubes, so that in this way the guard will
automatically adapt itself to exactly fill the opening beneath the sash. If the sash
is entirely closed, the guard is received by a groove a², of rail a', (Figure 4).
I prefer to so construct the guard, that it may be detached from the sash if
desired. To this effect the rods c, are not pivoted directly to the sash 6, but to an
intervening rail d. This rail is mortised at its upper edge as at d¹, for the reception
of locking bolts d², secured to sash b.
When the guard is not to be used, the rail d, is unlocked from sash b, and then
the rail d, together with the folded guard, remains concealed within the window
rail a', and is entirely out of action.
But when the guard is to be put into operation, the rail d, is locked to the
sash b, whereupon the guard will open and close with the sash in the manner
already described.
If desired additional diagonal rods e, may be attached to the sides of the
window frame and to the lower rail a¹, to reduce the opening left by the
telescoping rods.
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:
1. The combination of a window frame and sash with an intervening guard
consisting of a pair of pivoted rods and a pair of diagonally placed pivoted tubes
which telescope the rods, substantially as specified.
2. The combination of a window frame and sash with a rail d, adapted to be
locked to the sash, a pair of rods pivoted to said rail and with a pair of diagonally
placed pivoted tubes which telescope the rods, substantially as specified.
