Fig. is a like view at the y y or
Like letters of reference indicate corresponding parts in all the figures.
A is the lower window sash, and C the upper sash, D is the window frame, E is
the sill.
F, G, are the two parts of a plate, the part F, having projecting lips, H which
overlap part G at the centre, in order that the plate may be adjusted longitudinally
to fit any width of window.
I, I, are rods, secured near the outer extremities of plate F, G, and bearing at
their tops knobs, or enlargements J. K, K, are blocks, each having a central
perforation, L, as illustrated in Fig. 3, for the reception of a rod, I, and a thumb-
screw, P, for bearing upon the rod when raised or lowered, if desired.
When constructed and arranged as above described, my device may be easily
applied to any window sash, and air admitted between the meeting rails. When
the sash is raised, the plate will fall, its limit of movement being regulated by
means of the knobs, J, on the top of the rods, I, and it is held closely against the
lower rail of the sash when in any position. As the sash is closed down, the plate
will resume its original position. By having the blocks secured to the stiles of the
sash, it is not necessary to have any perforations through the plates, and by reason
of the plate being made in two parts, it can be used with varying width of window
sashes.
When found desirable two or more longitudinal plates may be used the one
sliding over the other when the sash is down, or, when the plates are secured
against movement, but one set of longitudinal plates will ordinarily be found
sufficient.
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 :-

sash, through which the vertical rods pass, substantially as shown and described.
2: The combination with a window sash, bearing blocks secured to the side
stiles, of a plate, resting against the lower rail of the sash, and provided with rods
which extend through perforations in said blocks, substantially as shown and
described.
3: The combination with a window sash bearing blocks secured to the side
stiles, said blocks being perforated longitudinally, and provided with thumb-screws,
of a longitudinally adjustable plate resting against the lower sash rail, said plate
bearing vertical arms near each extremity, passing through the longitudinal
perforations in the blocks, and terminating in enlargements or knobs, substantially
as shown and described.
4: The combination with the lower rail of a window sash, of one or more
adjustable leaves, attached thereto, and arranged to move therewith, substantially
as and for the uses and purposes shown and described.
5 The combination with the lower rail of a window sash of one or more
leaves, arranged to slide downward when the sash is raised, or to be carried upward
therewith, substantially as shown and described.
6: The combination with the lower rail of a window sash, of one or more.
movable leaves, adjustably secured thereto by a thumb-screw, or its equivalent, and
