We MICHAEL JOHN ROWLEY and CHARLES ALEXANDER WHEELER both of
14 Blandford Street, Portman Square, Middlesex, Engineers do hereby declare the
nature of our said invention to be as follows:-
The object of this invention is to so combine a plate spring, a roller in an
elliptical or elongated aperture, and a strip or block of india rubber or its
equivalent that when fitted to a movable window or screen all rattling vibration
and oscillation from wind or other cause is obviated, the appliances temporarilly
fixing the window or screen at any part of the sash or frame to which it may be
moved.
For the purpose of our invention we form a plate spring of any convenient shape
and we make eyes either by bending the slotted ends over or otherwise, elliptical or
elongated so that the axle of the roller which is held to it has a motion up or
down in the eyes or apertures To the plate spring we fix a strip of rubber, leather
or other suitable material so that it presses against the roller.
This rubber or its equivalent gives to the roller when the roller is moved in one
direction and bites it when the roller moves in the opposite direction the roller is
thus fixed and the window or screen firmly and securely held until pressure is
exerted to overcome the grip against the sash or frame.
The important feature in the invention is the elongated hole for the axle when
used in combination with the rubber or its equivalent.

We MICHAEL JOHN ROWLEY and CHARLES ALEXANDER WHEELER both of
14 Blandford Street, Portman Square, Middlesex, Engineers, 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 :-
The object of this invention, is, to, so combine a plate spring, a roller in an
elliptical, or elongated aperture, and a strip, or block of india rubber, or its
equivalent, that when fitted to a movable window, or screen, all rattling, vibration,
and oscillating, from wind, or other cause, is obviated; the appliances temporarily
fixing the window, or screen, at any part of the sash frame to which it may be
moved.
Our invention is clearly shown in the annexed drawings, A is a plate, forked at
one, or at both ends and turned back as eyes B, B, of elliptical, or elongated shape,
for the reception of the axle C of a roller D, which is held to it and has a motion
up, or down in the eyes, or apertures B, B. To the plate spring A, we fix a strip
of rubber, leather, or other suitable material E, as represented at Figures 1 and 2,
or a block of rubber, preferably in a metal case, or box F, as shown at Figures 3, 4,
and 5, so that it presses against the roller D. This rubber, or its equivalent,
gives" to the roller D, when the roller is moved in one direction, as shown at
Figure 4, and bites it, as represented at Figures 3, and 5, when the roller D moves
in the opposite direction; the roller is thus fixed, and the window, or screen, firmly
and securely held until pressure is exerted to overcome the grip.
"
Figure 6 shows the arrangement of the apparatus on a carriage window, and
Figure 7 shows a similar window in position. Figure 8 represents an arrangement,
in which the apparatus is fixed on the sash frame instead of on the window sash.
Figure 9 is a view, showing the back of the plate spring A; and Figure 10 a
double roller arrangement, in which two rollers D, D¹, are attached to one plate
spring A.
The important feature in the invention, is the elongated hole for the axle, when
used in combination with the rubber, or its equlvalent.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim is-
The apparatus shown in the annexed drawings, in which the roller has a freedoin
of motion when moving in one direction, and an automatic binding action, by
contact with a flexible body with which said roller comes into contact, in its
reverse travel in the elongated hole, as described for the purpose set forth.
