For this purpose I provide a lever pivoted at one end to a bracket or ears carried by
plate fixed to the meeting-rail of the outer sash, and to the meeting!
-rail of the inner
sash. I fix a plate formed with two vertical sides or strips having inwardly projecting
lips or flanges a short distance apart from each other. 'Underneath the free end of the
said lever is pivoted a wedge or taper-shaped block or plate which can be turned' by a
handle fixed to the axis or pivot pin of the said block.
When required to lock the sashes the lever is turned down on to the plate on the
inner sash its pivoted block passing between the lips or flanges on the said plate. Its
handle is then turned so as to bring the wedge or taper sides of the block underneath
the projecting lips or flanges of the plate thus drawing the sashes tightly together and
securely locking them in their closed position."
The sashes are unlocked" by turning the handle back in a line with the lever, thus
turning the block so as to permit of the lever being raised into a vertical position on
outer sash and so allowing the sashes to be raised or lowered.

An improved window-sasn rastener.
I, JOHN AMYES, of 15, Queens Gate, London, S.W., Butler, 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 an improved window-sash fastener having for object to
prevent the rattling of the sashes and the unlocking of the same from outside the
window.
For this purpose I provide a lever pivoted at one end to a bracket or ears carried
by a plate fixed to the meeting rail of the outer sash, and to the meeting rail of the
inner sash I fix a plate formed with two vertical sides or strips having inwardly pro-
jecting lips or flanges a short distance apart from each other. Underneath the free

page_text: end of the said lever is pivoted a wedge or taper shaped block or plate which can be
turned by a handle fixed to the axis or pivot pin of the said block.
When required to lock the sashes the lever is turned down on to the plate on the
inner sash its pivoted block passing between the lips or flanges on the said plate. Its
handle is then turned so as to bring the wedge or taper sides of the block underneath
the projecting lips or flanges of the plate thus drawing the sashes tightly together and
securely locking them in their closed position.
The sashes are unlocked by turning the handle back in a line with the lever, thus
turning the block so as to permit of the lever being raised into a vertical position on the
outer sash and so allowing the sashes to be raised or lowered.
In order that the Invention may be more clearly understood reference is had to.the
accompanying drawings in which Fig. 1'is a side view of my improved fastener showing
it in locked position. Fig. 2 is a similar view showing it open and Fig. 3 is a
detail view showing the locking device. A is the plate screwed on the meeting rail B,
belonging to the upper sash. This plate is provided with the central post or lug a to
which the lever C is pivoted. This lever is formed with the square corner cat one
side which prevents it being turned too far back. To the other end of the lever the
plate D is pivoted this plate or block having its ends curved or bevelled so, as to taper
towards opposite corners. To the upper side of the lever the handle d is fitted by
means of which the plate can be turned. On the other meeting rail B' a plate E is
screwed baving the side pieces e under-cut or grooved to form channels. To lock the
fastening the lever C is turned over the second plate and the locking plate or block D
is turned so as to enter between the two side pieces e. On turning the arm round at
right angles to the lever the plate will be caused to lock in the channels formed to
receive it and the sashes will thus be securely fixed together.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:
1. In an improved sash fastener the combination with a plate on the meeting rail
of the upper sash, a lever pivoted to the said plate and turning vertically, and a wedge
shaped block or plate pivoted to the said lever, of a plate on the other meeting rail
having channelled sides formed to receive the wedge when the latter is turned into
locking position substantially as described and for the purposes specified.
2. In an improved sash fastener the combination with the plate on the meeting rail
of the upper sash, a lug on the said plate, a lever pivoted to the lug, and a wedge block
or plate pivoted to the end of the lever, of a plate on the other meeting rail having
side bars grooved or undercut to receive the wedge plate substantially and for the
purposes specified.
3. An improved sash fastener having a vertically turning lever, a wedge plate
pivoted to the said lever, a handle fitted to the wedge plate and a plate on the meeting
rail of the lower sash adapted to receive the wedge plate, substantially as described
and shown in the accompanying drawings and for the purposes specified.
