Improvements in Window Ventilators.
I, JULIUS DE LONG, of 128 Pearl Street, New York City, N.Y.,. United
States of America, Merchant, 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 :-
My invention relates especially to devices designed to attach to windows for
securing ventilation in apartments, and has for its object the provision of a simple,
cheap and effective device whereby a space may be left between the meeting rails
of sashes for the passage of air, the opening beneath the lower sash being
effectually closed, and direct draughts of air avoided.
To attain the desired end, my invention consists essentially in a plate having a
narrow flexible lip at the bottom edge and a wide flexible lip projecting horizontally
from the face of the plate near its upper edge and means for removably securing
said plate in a slanting position upon a window sill.
In the accompanying drawings,
Fig. 1 is a perspective view of a window showing my attachment as employed
therewith.
Fig. 2 is an enlarged, vertical sectional view at line
Fig. 3 is an enlarged face view of one of the plate
removed from the window casing.

holding devices or cleats,
Similar numerals of reference, wherever they occur indicate corresponding parts
in all the figures.
1 is a plate, preferably made of thin wood. At the bottom is fixed a narrow
projecting tongue 2 of flexible material. Near the upper edge of one of the faces
of the said plate 1 is fixed a wide projecting tongue 3, also made of flexible
material.
4 is a cleat or plate, preferably made of metal, said plate having projecting
lips 5 and 6 extending diagonally across its face, as particularly illustrated in
Fig. 3.
7 is a spring, fixed at its upper edge as at 8, and projecting slightly into the
space between the lips 5 and 6. When this cleat is made of metal the centre is
cut through and one side turned outward to form the lip 5; a portion of the other
edge is turned outward to form the lip 6, and the remaining portion on that side of
the cut is severed from the plate with the exception of the upper part 8, thus
forming the entire cleat and spring of a single piece of metal which may be readily
attached to the sides of a window frame by means of nails or screws.
When the various parts of my device are assembled for use and attached to a
window, as illustrated in Fig. 1, the plate 1 is removably slipped into the holding
devices or cleats 4, the springs 7 preventing any movement of said plate when the
lower sash is raised. By giving the plate a sloping position, as illustrated, any
lifting device, such as 9, attached to the lower sash may be readily reached by the
hand, the wide flexible tongue 3 readily yielding to the fingers. When the lower
sash is raised, as in Fig. of the drawings, the space there beneath is completely
closed, while ample space is left between the meeting rails of the sashes for the
admission of fresh air, the draught being thrown upward into the warm and vitiated
atmosphere at the top of the apartment.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. A window attachment, in which is comprised two slotted cleats, each provided
with an outwardly projecting spring tongue, said cleats being secured to the sides
of the window frame near the sill; and a sloping plate baving a narrow flexible
projecting lip at its lower edge, and a wide flexible lip near its upper edge,
arranged to bear against the lower rail of a window sash, the whole combined and
arranged to operate, substantially as shown and described.
2. In a device of the character herein specified, a plate, having a narrow flexible
lip at the bottom edge, and a wide flexible lip projecting horizontally from the face
of the plate near its upper edge in combination with means for removably securing
said plate in a slanting position upon a window sill.
3. In a device of the character herein specified, the combination with the
removable plate, of a slotted holding cleat provided with a securing spring
projecting into the slot.
4. In a device of the character herein specified, a slotted holding cleat, provided
with a spring tongue projecting into the slot.
Dated this 14th day of March 1895.
