Improvements in Holders and Fasteners for Sliding Windows.
ABRAHAM LEAVER, Weaver, 21, Stanley Street, Nelson, Lancashire, THOMAS KING,
Painter & Builder, 1, Chapel Street, Barnoldswick, Yorkshire, do hereby declare
the nature of this invention to be as follows:
-
A box fastened in window frame on each side containing shaft, roller wheel,
ratchet wheel and swinging plate or friction bar. The roller wheel projects outside
the box and is free to revolve when the window is raised but when the window is
lowered the wheel is locked by means of a metal pin which holds the ratchet
wheel and brings out the swinging plate or friction bar against the window sash.
The shaft may be fixed in stationary or spring brackets and the roller wheel may
be made of or covered with rubber or other flexible material if desired.
(On the
inner side of box may be fastened a plate which projects about the same distance
as roller wheel & slides in the same slot in window while on the window sash on
each side are fixed an angle shaped plate which comes in contact with projection
when the window is closing & is moved so as to automatically slide a bar or lock which
is fixed on window sash under the projection & into a cavity in the box or window
frame the window being thus self fastening.)

Improvements in Holders and Fasteners for Sliding Windows,
ABRAHAM LEAVER, Weaver, 21, Stanley Street, Nelson, Lancashire, THOMAS KING,
Painter and Decorator, 1, Chapel Street, Barnoldswick, Yorkshire, do hereby declare
the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
The object of this invention is to dispense with ropes, weights and pullies in
sliding windows; and to automatically lock and securely fasten the window, when
closed or when open for ventilation purposes.
The invention consists of box containing wheel or roller, working or revolving
in spring bracket as shown in drawing's; the wheel may be made so as to revolve
when the window is both raised & lowered; or it may be made so as to revolve
when the window is raised, & lock when it is being lowered; it may also be made
so as to bring out a friction plate or bar against the window side when the wheel

be also used to lock the window.
DESCRIPTION OF DRAWINGS.
Fig. 1. Shows front elevation of box with roller (a) and brackets (b).
Fig. 2. Shows end elevation with box in section of wheel (c) and bracket (d)
with spring and split pin.
Fig. 3. Shows plan of wheel bracket and spring with cover of box removed the
wheel or roller here shown is free to revolve in either direction.
Fig. 4. Shows front elevation of window sash and window frame in section,
also box with side removed so as to show how the box is fixed or fastened on the
window frame, and the action of the wheel or roller against the window sash, the
wheel tends to assist the window sash up while the pressure of the spring balances it
when raised.
Fig. 5. Shows end elevation of window frame with back elevation of boxes, this
figure shows two boxes on each side of window one for each sash on each side.
Fig. 6. Shows front elevation of box with roller and rack in centre of wheel, also
show the pin E which locks the wheel, when the window is raised the wheel
revolves in an upward direction and the pin E is raised and has no action on the
rack wheel or ratchet portion of the roller wheel, but when the wheel attempts
to revolve in the opposite or downward direction the pin E drops down and comes
in contact with the flat face of one of the teeth or ledges of the ratchet portion of
the wheel and thus prevents the wheel from revolving further in that direction.
Fig. 7. Shows end elevation of box with wheel ratchet falling and rising pin,
bracket and spring the action of the pin and ratchet wheel will be more clearly seen in
this figure.
Fig. 8. Shows plan of wheel and bracket with opening for falling and rising
pin in bracket F.
Fig. 9. Shows front elevation of box with wheel ratchet and friction plate G, the
wheel is free to revolve in an upward direction that is when the window is being
raised, but it is prevented from revolving in the opposite or downward direction
by the teeth or ledges of the rack coming in contact with the swing plate at M,
which is pushed back while the portion N is pressed against the sides of the window
sash when the window is lowered.
Fig. 10. Shows end elevation of box with wheel and rack & friction plate H, also
showing double springs for bracket, when M' is pushed back by the teeth revolving
in a downward direction the portion N₁ is pressed against the window sash and
acts as a brake when the sash is lowered; the box is fixed as shown in Figs. 4
and 5.
Fig. 11. Shows front elevation of box with double bracket and springs with two
wheels free to move in either direction, and fixed as shown in Fig. 14.
Fig. 12. Shows end elevation of box in section with wheel, bracket and spring.
Fig. 13. Shows plan of box with cover removed so as to show double bracket,
two wheels, and two springs, also partition in box.
Fig. 14. Shows end elevation of window frame with back elevation of double
box fixed.
Fig. 15. Shows the front and end elevation of wheel inside the flanges of which is
covered with india-rubber these may be used with or without springs if required.
Fig. 16. Shows front elevation of box showing wheel and bracket, this is for the
purpose of locking the windows.
Fig. 17. Shows end elevation of lock out of action, this is brought about by
pulling back the bracket rod and inserting the pin as shown at P.
Fig. 18. Shows plan of lock box in action, in this figure the bottom plate of the
box is extended beyond the back of the box so that when the bracket rod is
pulled back by means of the small handle R which revolves on the rod, it can be
turned round so that the cross bar, S, will come in contact with and be held back
by the projecting bottom plate.

page_text: Fig. 19. Shows end elevation of lock box out of action this figure shows the
bracket rod drawn back and the revolving cross plate of the handle in contact with
the bottom projecting plate T, this handle is secured on the bracket rod by means of
a split pin through the rod as shown.
Fig. 20. Shows front elevation of window sash and frame with back elevation of
lock box I, also showing recesses cut in the upper sash so as to lock the windows
when they are either closed or partially open for ventilation, when the lock is
in action it pushes the wheel into the recesses as the lock is brought oppositive
them.
Fig. 21. Shows end elevations of window sash and window frame in section so as
to show the action of the lock or fastener, and also to show how it may be fixed,
also showing recesses for lock cut in the upper sash any number of these may be
cut, one section showing the lock in action and the other out of action.
In action the boxes Fig. 1, Fig. 6, Fig. 9, Fig. 11, may be fixed in any part of
the window frame but the position shown in Fig. 4, Fig. 5, Fig. 14, is preferred:
the wheel is intended to assist the window up, and the spring to keep it in contact
with the window sash, while the pin and rack in Fig. 6, and the rack and friction
in Fig. 9 are intended to act as a brake on the sash when the windows are being
lowered.
CLAIMS.
Having now particularly described and ascertained the nature of our

in box as shown.
2. Spiral spring bracket, with roller and rack combined, (the rack may be either
in the centre as shown or at the side) free to revolve when the window is raised
and to lock when the window is lowered or stationary by means of a falling pin as
shown in Fig. 6, or by means of a pawl secured to bracket.
3. Spiral spring bracket with roller and rack combined to revolve when the
window is raised and to lock when being lowered or when the window is stationary
by means of a swing friction plate fixed under the rack by which it is pressed
against the sash when the window is being lowered, and fixed in box as shown
