Improvements in Fastenings for Sliding Window Sashes.
FREDERICK WOODWARD, and ARTHUR GEORGE WOODWARD, both of 7 Matilda
Street, Islington, London, N., Revolving Shutter Makers, do hereby declare the
nature of our said invention to be as follows:-
The object of our invention is to effect improvements in fastenings for sliding
window sashes, by means of which such sashes may be secured in any required
position.
According to our invention we fit the upper part of the lower sliding sash with a
pivoted catch, the upper end of which is capable of entering any one of a number
of holes in a perforated plate fixed to the stile of the upper sash. A hook is also
fitted which engages the lower end of the pivoted catch, and a pin is attached thereto
whereby it is locked. A bolt is fitted to the lower sash which may be caused to
enter one of a number of holes in a plate fitted to the front bead of the window.
Our aforesaid appliances may be fitted to one or both sides of the sliding sashes,
as required; the sashes being thereby secured in a closed, or in an open position for
ventilation, without danger from external interference.

Improvements in Fastenings for Sliding Window Sashes.
WE, FREDERICK WOODWARD, and ARTHUR GEORGE WOODWARD both of 7 Matilda
Street Islington London, N. Revolving Shutter Makers, do hereby declare the
nature of our said 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 our invention is to effect improvements in fastenings for sliding
window sashes, by means of which such sashes may be secured in any required
position.
And in order that our said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings in which
similar letters of reference indicate corresponding parts.
Fig 1 is a sectional side elevation and Fig 2 is a front elevation of a portion of a
sliding sash window with our fastening attached.
Fig 3 is a sectional plan view a is the upper sliding sash, b is the lower sliding
sash and c is the front bead of the window frame d. We fit a pivoted catch e,
provided with a tooth e, to the upper part of the lower sash b and provide the stile
of the upper sash a with a perforated plate finto the holes g of which the tooth el
dips. The plate f may be of any desired length and may be formed with any
desired number of holes.

page_text: The lower end of the pivoted catch e is formed as a tail h normally pressed
outwards by a spring i whereby the tooth e is pressed into the holes g of the plate f.
The catch e is provided with means whereby the same may be locked in position
(engaged or disengaged) such for instance as a hook k, and loop Z and chain m, (or
a pin may be used for a similar purpose) to retain the catch in a disengaged
position as shown in Fig 2. In order to lock the catch in an engaged position we
make use of a sliding bolt n the end o of which is formed as a block to prevent the
catch being released when such bolt is inserted behind the tail of the catch.
The lower sash is provided with a bolt or pin p capable of being inserted through
the lugs into any one of a number of holes formed in the bead c, a perforated
plates being secured thereto. The bolt or pin p is preferably formed with a short
feather or projection p' and one of the lugs is formed with a slot r' capable of
allowing the projection p' to pass through, the bolt or piu being then given a half
turn to lock. A chain is preferably provided to prevent accidental loss of the bolt
or pin p.
It will thus be seen that the catch e secures the upper sash and the bolt or pin p
secures the lower sash, while the bolt n locks the catch e so that the sashes. cannot
be raised or lowered independently of one another; by these means the sashes may
be opened a short distance for ventilation or other purposes and yet be secure
against further opening or external interference.
Our aforesaid appliances may be fitted to one or both sides of the sliding sashes,
as required.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim
is -
1 The improved fastening for sliding window sashes, substantially as set forth.
2 In fastenings for sliding window sashes, the combination of a pivoted catch e
with a perforated plate f, the catch being formed with a tail with or without the
hook loop and chain m whereby the catch may be secured in a disengaged
position and with or without the sliding bolt n for securing the catch in a locked
position, substantially as herein before described and illustrated by the drawings.
3 In fastenings for sliding window sashes, the combination with the fastening
claimed in claim 2 of a bolt or pin p chain t lugs r projection p¹ and slot, and
perforated plate 8, operating substantially as hereinbefore described and illustrated
by the drawings.
