page_text: I, GEORGE JAMES POLLARD, of 47, Queen's Road, Bayswater, Cycle Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved sash fastener and has for its object to
provide a simple construction enabling the sashes to be secured together in a
firm and efficient manner without danger of being opened from the outside.
In carrying out my invention a spindle is employed fitted to the meeting rail
of the sash and provided with a spring which withdraws when released into
the recess formed to receive it.
The meeting rail is perforated to receive this spindle and a plate is fixed at
front and back having holes through which the spindle passes. The plate at the
front of the meeting rail is fixed in a recess, this recess being adapted to receive
the head of the spindle. This head is preferably pointed at each end and is
of wedge or rounded shape.
The other meeting rail is furnished with a plate having a rounded hole or
recess through which the head is adapted to pass. The back of the plate is
formed with a slanting ledge at each side of the slot so as to form an inclined
surface. On the head being passed through and turned round it will slide over
this slanting surface binding the sashes together. The meeting surfaces of the
rails are made slanting but the plates may be vertical both the meeting rails
being formed with recesses to allow of this.

A NOW OP
I, GEORGE JAMES POLLARD, of 47, Queen's Road, Bayswater, Cycle Engineer,
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 sash fastener and has for its object to
provide a simple construction enabling the sashes to be secured together in a
firm and efficient manner without danger of being opened from the outside.
In carrying out my invention a spindle is employed fitted to the meeting rail

page_text: of the sash and provided with a spring which withdraws it when released into
the recess formed to receive it.
The meeting rail is perforation to receive this spindle and a plate is fixed at
front and back having holes through which the spindle passes. The plate at the
front of the meeting rail is fixed in a recess, this recess being. adapted to receive
the head of the spindle. This head is preferably pointed at each end and is
of wedge or rounded shape.
The other meeting rail is furnished with a plate having a rounded hole or
recess through which the head is adapted to pass. The back of the plate is
formed with a slanting ledge at each side of the slot so as to form an inclined
surface. On the head being passed through and turned round it will slide over
this slanting surface binding the sashes together. The meeting surfaces of the
rails may slope but the plates may be vertical both the meeting rails being
formed with recesses to allow of this.
In order that the invention may be more clearly understood, reference is had
to the accompanying sheet of drawings in which Fig. 1 is a cross section of the
meeting rails of the sash showing my improved fastener, Figs. 2 and 3 show
the bolt and Fig. 4 is a detailed view of the plate receiving the end of the bolt.
The meeting rail A is formed with the passage a within which the bolt B is
placed. The end of the passage or hole a is closed by the plate C at the back
and at the front of the meeting rail, the recess a¹ is formed the plate c closing
the hole at this end. The bolt B is formed with the head 6 which is of hammer
shape and of a width about equal to the diameter of the bolt.
At the other end of the bolt a finger piece or handle b¹ is provided and is also
formed with a collar 62 preventing it being withdrawn. Around the bolt the
spring D is placed causing the bolt to be withdrawn within the recess when
released.
The other meeting rail A¹ is provided with a recess a² and in the face of the
meeting rail the plate E is fixed. This plate is formed with the opening e adapted
to receive the head of the bolt and is provided with the two sloping surfaces e¹
one on each side of the opening.
On pushing the bolt forward the head will pass through the opening in the
plate, and on turning the bolt the head will slide over the sloping surfaces until
the sashes are withdrawn.
It will then be prevented from turning further and the sashes will be securely
locked. On turning the bolt back the spring will withdraw it automatically
from the second meeting rail and the sashes can then open.
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 bolt carried in the
meeting rail of the lower sash, a spring around the said bolt and a head on its
extremity, of a plate fixed in the other meeting rail having an opening to receive
the head of the bolt and inclined surfaces on the inner side of the plate over which
the head slides, substantially as and for the purposes specified.
(2) In an improved sash fastener, the combination with a bolt carried in the
meeting rail of the lower sash, a spring around the said bolt, a head on its end,
a collar on the bolt and a plate fitted to the meeting rail, of a plate fixed in the
face of the other rail, an opening in the said plate and two sloping surfaces over
which the head of the bolt can slide, substantially as and for the
specified.
purposes
(3) The improved sash fastener consisting of a sliding bolt having a spring
and a head fitted to the meeting rail and the lower sash and a receiving plate
having two inclined surfaces fitted to the other meeting rail constructed and
