COMPLETE SPECIFICATION.
Improvements in Sash and other like Window Fasteners.
1, CHARLES DEAN of Walsall Road, Willenhall, in the County of Stafford, Manu-
facturer, 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:-
This invention relates to means or window fastening appliances, commonly called
sash-fasteners, and which said invention consists 1st in constructing and arranging in
a simple and efficient manner, the fastening means, whereby the meeting rails are
secured and drawn together. 2ndly in key or other locking appliances, for securing
the fastener-bars of the said fastening means, whereby the said meeting rails are
locked, as well as being fastened.
Figure 1 of the accompanying drawings, represents in side elevation, a sash
fastener, constructed and arranged according to my said invention, and which said
fastener is shown applied to the meeting rails of window, when the said window is
closed.
Figure 2 represents a plan of figure 1, but with the enclosing cap or casing of
the fastener removed, and with the fastener-bar shown catched, but not locked.
Figure 3 represents a complete horizontal section, upon the dotted lines A B
figure 1, but with the fastener-bar, locked in its catched or fastening position.
Figure 4 represents a like view as figure 2, but with the fastener-bar unlocked, and
removed from its catched position, and just before the same is taken back to its normal
position, by the expansion of the coiled spring, as in figure 5.
Figure 6 represents a top side plan of the catch-plate.
Figure 7 represents an elevation of the shoulder end of the same.
Figure 8 represents an inside side elevation of figure 6.
Figures 9 and 10 represent a top side plan and underside plan of the fastener-bar,
whilst figure 11 is a side elevation of the same.
Figures 12 and 13 is an edge view and plan of the attachment plate, whilst
figure 14 represents the locking shoot of the fastener, and figure 15 a lever tumbler
of the same.
The same letters of reference, indicate corresponding parts, in the several figures of
the accompanying drawings.
a is the fastener bar, with hooked end a³, and stem end a³, terminated by a knob a*.
One side of the stem end of the said fastener-bar, has a seat or socket a³, wherein one
end of a spring b, takes, whilst the other side has a blocking shoulder a, in front of
which, the traversing shoot, c, of the locking part of the apparatus, comes, on the said
shoot being shot by the rotation of the key d, which lifts the tumbler lever e, whose
gap e, allows the post ², carried by the shoot C, to pass.
A gap of the shoot works upon a guide f, which has a peg 2, carried by the
attachment plate, and upon which peg f, the fastener-bar works as a fulcrum,
through the intervention of the long slot a", made within it, which admits of the said
bar, reciprocating and rocking after the manner of a beam, in order to connect and
disconnect the end a², with and from the catch shoulder, of the catch plate g, carried
by the top meeting rail h, contiguous to the lower meeting rail i.
The end 6, of the spring b, seats itself within a socket rest f³, carried and made
fast with the attachment plate f.
The locking and fastening parts of the fastener, are enclosed by a cap j, which has
a key-hole, wherethrough the key is introduced, for locking and unlocking the
fastener-bar.

page_text: OPERATION.
To connect, fasten, and lock the meeting-rails of the window sash together, first
press inwards, and at the same time, turn aside or oscillate the fastener-bar as in
figure 4. Then release the same, when the hooked end a³, of it, will by the reaction
of the spring, be made to engage with the shoulder catch g2, of the catch-plate g,
thus connecting and fastening the said meeting rails of the sash together as in
figures 1 and 2.
To lock the fastener-bar, in its fastening position, insert the key d, through the key-
hole, then rotate the same, when the lever tumbler e, will be lifted, and the shoot c,
shot into the position as shown at figure 3, with the fore part of the said shoot, coming
in front of.a blocking shoulder a, thereby locking the said fastener-bar, in its fastening
position.
To unlock and unfasten the said fastener appliance, turn the key in the reverse
direction, when the shoot will be withdrawn from in front of the shoulder of the
fastener-bar, thus admitting of the said bar being first pressed inwards, and then
turned side ways upon its fulcrum peg, so as to remove its hooked end from the catch
shoulder of the catch plate.
I wish it to be understood that the fastening part of the sash-fastener, may be
employed without locking means, although I prefer, where additional security is
desired, to use in conjunction with the fastener bar, such locking means, as
described.
The meeting rails are drawn together principally by the action of the spring.
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
First A sash or other like window fastener, fastening or securing the meeting-
rails, by means of a combined sliding and oscillating fastener-bar, with an hooked end,
which is adapted to engage with a shoulder catch upon one of the said rails, substan-
tially as described and set forth.
Secondly-A sash or other like window fastener, consisting of a fastener bar a, a²,
a³,
with parts a, a, and slot a², adapted to slide and oscillate upon a fulcrum pin,
2 and
with, the hooked end, engaging with a shoulder catch g2, of a catch plate g; whilst the
fastening and return movements of the parts of the fastener-bar, is effected by an
interposed spring b, taking a fixed rest upon a stationary socket seat f³, and which
said parts, are constructed, arranged, and operate, substantially as described and set
forth.
Thirdly -A sash or other like window fastener, locking the fastener-bar of the
construction, or essentially of the construction and action as herein described, by
means of a shoot or limb, with or without a tumbler lever or levers actuated by a key,
substantially as described and set forth.
Fourthly A locking sash or other like window fastener, consisting of a fastener-
bar, spring, locking-shoot, tumbler lever, shoulder catch, and other parts, all arranged
and combined, substantially as described and set forth.
Dated this 2nd day of June 1890.
