I do hereby declare the nature of this invention to be as follows:

Description of invention constructed in 3 parts No. 1 being a long plate with a
continued number of lockholes to the extent of 6 to 7 inches along the face of plate
these are circular in shape comenceing about half inch in diamitor on the face of
plate and so diminishes down to a point divisions between lockholes is only a
pointed ridge but increases toward the depth the same as the lockholes is on the
face of plate. No. 2 is a cylinder block the base of this has screw holes for fixing
purpoeses while its upper portion forms the cylinder the cylinder is 2 inches in
length and so is elevated 2 inches from base. No. 3 is the key one end forms a knob
while the barrel part is so attached to the cylinder there is a spiral slott in the
barrel part a screwhole is drilled through the block to the cylinder a screw is fixed
thereto and conect into the spiral slott of key by this process the key is conected
and as the knob is turned the barrell revolves and works in and out of the cylinder
by giveing the key half a turn to the right it tightly locks the same, process to the
left so unlocks this new invention affords all that is required in ventilation by this
new process it does away with ordinary sash fasteners that is usely fixed in the
centre of windows also it does away with wedges as so commonly used for
tightening the sashes this is the improved advantages in this improved ventilating
sash fastener when the sashes are locked they are tightened in every way leaveing
them immoveable top and bottom sash can be so regulated for ventilation from
half an inch to six inches and they can be locked to any part to that extent as
may be required. Also by this new process when the two sashes haveing been
closed as you turn the knob to lock so it forces the two sashes tight up and down
in there respective places and so tightening them in every way makeing them secure
and burgular proof.

COMPLETE SPECIFICATION.
An Improved Ventilating Sash Fastener.
I, JOHN TRICK of 24 Hartismere Road, Fulham London, S.W. Carpenter and
Joiner, 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 improvements in sash fasteners and has for its object to
provide means and apparatus whereby the window, or sashes thereof may be
partially opened at the top or at the bottom or both for the ventilation of the
apartment, and may in that position be locked or secured from the inside, and so
rendered burglar-proof, and unable to be rattled or shaken by the wind.
The said improved fastener consists of three distinct parts, the first being a long
plate having lock-holes formed on the face thereof, which is fixed to the side rail
of the upper sash near to the meeting rail.
The second part is a raised cylinder mounted on the upper surface of the meeting
rail of the lower sash opposite to the said long plate attached to the upper sash, the
FD 21

page_text: object of such cylinder being to carry a pin or key which constitutes the third part
of the said invention.
For the better explanation of the invention, the accompanying sheet of drawings
is appended hereto; in which
Figure 1 represents a front view of the first named two portions of the invention,
the third part or key being omitted for the sake of clearness.
Figure 2 represents part section and part side view of the whole of the
contrivance and
Figure 3 shows an enlarged view of the key or pin, which constitutes the 3rd
portion of the said invention.
The like letters of reference indicate the like parts throughout.
a is a plate of any suitable length, and formed of any suitable metal, furnished
with a succession of lock-holes which are circular at the face of the plate and
diminish to a point at their bottom or otherwise as desired. Said plate is furnished
with screw holes at top and bottom tliereof for attachment to the upper sash side
rail as before mentioned. c is a cylinder open at both ends, formed in any suitable
metal, and furnished with a base portion designed to rest flat upon the upper
surface of the lower sash meeting rail d.
The said cylinder base is provided with screw holes to enable the whole to be
firmly screwed down to the meeting rail. A screw-threaded hole is formed up
through the centre of the cylinder c, and from the under surface of the base
thereof, the object of which being to receive a screw of such length that its
point projects for a short distance into the hole or bore of the cylinder through
which the pin or key passes, this projecting point of the screw is indicated by the
letter e.
The third portion of the invention is the pin or key which is furnished with a
point of shape corresponding to the lock-holes in the plate a, and into which it is
designed to be placed. At the opposite end of the key is formed an enlarged disc
or other suitably shaped handle to turn with the finger and thumb (2). At about
the centre of the barrel part of the key, a spiral slot is formed on the surface thereof g,
the object of such slot being to engage with the screw point e projecting into the
interior of the cylinder c, so that when the key is inserted into the cylinder it can
by turning with the finger and thumb be caused to travel backwards and forwards
as desired.
It will be readily understood from the afore going description that the lower sash
or the upper sash or both of them can be opened to the extent of the length of the
plate a, or to any less extent, and be securely fixed in that position by turning
round the key so as to place the point thereof into whichever of the lock-holes of
the plate a it is opposite, and thus making it impossible to move the sashes from
the outside.
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 :-
The improved ventilating sash-fastener consisting of a plate containing lock-
holes attached to the upper sash, in combination with a cylinder mounted on the
meeting rail of the lower sash and carrying a spirally slotted pin, the point of which
is designed to be placed in the lock holes of the above mentioned plate, all
substantially as described in the foregoing Specification and illustrated by the
accompanying drawings and for the purpose therein set forth.
Dated this 30th day of November 1891.
