PROVISIONAL SPECIFICATION
Improvement in Sash-fastenings for Window-sashes and Doors.
I, JOHN CORMELL of Lansdown Cheltenham in the County of Gloucester Merchant
do hereby declare the nature of this invention to be as follows:-
The object of this invention is simplicity and the gripping together of the two
parts of a window sash or door to prevent them rattling, and to securely fasten them
together.
In constructing a fastening according to this invention I make a short piece of
round metal barrel, I cut a diagonal channel in the top of it and fit a short round
bolt in it, with an arm to work in the channel. This is fixed on one part of the
sash or door. I then make a staple of similar shape to the barrel for the bolt to work
into and fix on the other sash or part of door. I make a female screw thread of
peculiar shape on the end of the bolt and a male thread in the staple. Upon working
the arm in the diagonal channel of the barrel it causes the threads to grip each
other and to fasten and tighten the two parts of the window sash, or door,
together.

COMPLETE SPECIFICATION.
Improvement in Sash-fastenings for Window-sashes and Doors.
I, JOHN CORMELL of Cheltenham in the County of Gloucester, Merchant, 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 has for its object simplicity in action, and the gripping together
the two parts of a sash or door to prevent rattling and to securely fasten them.
I construct this fastening by making the body of it in the shape of a piece of
round or other shape barrel or tube and making a channel or slot in a diagonal
direction on the top of it. I then fit into it a bolt of round or other shape on
the end of which I form a peculiar and special female screw thread and fix into
the bolt an arm to work into the said channel or slot. I make a staple with a
male screw thread in it of similar pitch and to correspond with the female thread
in the bolt; upon turning the bolt by means of the arm or pulley; the female
screw of the bolt grips the male thread in the staple, pulling together (if loose)
the two parts of a sash or door, and securely fastening them together.
Having thus set forth the nature of my invention I next proceed to describe it
with reference to the drawing and figures and letters marked thereon.
Fig. 1 is an elevation of the improved fastening herein mentioned, the two parts
of the fastening are shown apart. At the end of the bolt is the female screw
thread marked "B" which is made wide at the mouth to cause it to grip the male
thread of the staple in case of the two parts of a sash or door not fitting closely
together. The part marked "C" is the staple and the dotted lines indicates the
male screw thread. The part marked "A" is the long arm which works in the
channel of the barrel and causes a backward and forward motion of the bolt.
Fig. 2 is a perspective drawing of the same thing with the two parts closed
together.
Fig. 3 is a perspective drawing of the same thing with a short arm, pulley, and
cord instead of a long arm, for convenience of fastening high window sash or door.

page_text: 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
1st. To use the form of screw thread in the bolt and staple in any metal and
as described.
2nd. To use any other form of screw thread in bolt or staple operated on by a
diagonal slotted barrel and arm.
3rd. To use the barrel with its diagonal channel with an ordinary bolt; each and
all having application to fastening sashes and doors.
Dated this Eighteenth day of October 1890.
