page_text: LETTERS PATENT to William Westley, of Derby, Engineer, and
Richard Bayliss, of Derby, Surveyor, for the Invention of
"AN IMPROVED FASTENER, APPLICABLE TO THE FASTENING OF WINDOW
SASHES. TABLES AND OTHER SIMILAR PITBA
PROVISIONAL SPECIFICATION left by the said William Westley
and Richard Bayliss at the Office of the Commissioners of
Patents, with their Petition, on the 23rd December 1852.
We, WILLIAM, WESTLEY & RICHARD BAYLISS, do hereby declare
the nature of the said Invention for "AN IMPROVED FASTENER, APPLI-
CABLE TO THE FASTENING OF WINDOW SASHES, TABLES, AND OTHER SIMILAR
PURPOSES," to be as follows.
Fig. 1, represents our Invention in front view; Fig. 2, represents
a transverse section of the same thro' the middle A, B; and Fig. 3,
represents a transverse section thro' the end C, D. It consists of the
part a, to be attached to one of the sashes of a window, and the part
b, to be attached to the other sash of the said window. The inner
face c, of the vertical side of the part a, is inclined as shown in Fig.
3, and the inner face d, of the vertical side of the part b, is also

page_text: inclined, so that when the part a, descends, or the part b, ascends,
the two inclined faces c, d, engage against one another, and draw
the sashes together; at the same time the tongue f, falls back in the
direction indicated by the arrow; and when the horizontal parts a, b,
are in the same plane, the upper edge e, of the tongue f, is forced by
the spring g, under the edge of b, and the sash to which the part a,
is attached cannot be raised until by pulling forward in the direction
indicated by the arrow upon the thumb plate h, the tonguef, is disen-
gaged from under the edge of b; when the sash may be raised. The
same fastening may be applied to tables and other articles.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said William Westley and Richard Bayliss
in the Great Seal Patent Office on the 21st of June 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc,
WILLIAM WESTLEY, of Derby, Engineer, and RICHARD BAYLISS, of
Derby, Surveyor, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of December, in
the year of our Lord One thousand eight hundred and fifty-two, in
the sixteenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said William Westley and Richard
Bayliss, Her especial license that we, the said William Westley and
Richard Bayliss, our executors, administrators, and assigns, or such
others as we, the said William Westley and Richard Bayliss, our
executors, administrators and assigns, should at any time agree
with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "AN IMPROVED FASTENER, APPLICABLE TO THE
FASTENING OF WINDOW SASHES, TABLES, AND OTHER SIMILAR PURPOSES," upon
the condition (amongst others) that we, the said William Westley and

page_text: Richard Bayliss, or one of us, by an instrument in writing under
our hands and sculs, or under the hand and seal of one of us,
should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said William Westley and Richard
Bayliss, do hereby declare the nature of the said Invention, and in
what manner the same is to be performed, to be particularly de-
scribed and ascertained in and by the following statement thereof,
reference being had to the Drawing hereunto annexed, and to the
figures and letters marked thereon (that is to say):
Figures 1, 2, 3, 4, 5, and 6, represent our Invention applied as a
fastener for window sashes; and Figures 7, 8, 9, and 10, represent
the same applied as a fastener for tables. Figure 1, represents our
sash fastener in front view unconnected with window sashes); Figure
2, represents the same in vertical transverse section (fixed on the
sashes of a window), the said section being taken through the line a.
Figure 1, and Figure 3, also represents the same in transverse ver-
tical section (fixed on the sashes of a window), the said section being
taken through the line b, Figure 1. The part c, of the fastening
is attached to the meeting bar d, of the upper sash, and that part of
the said fastening marked e, is attached to the meeting bar f, of the
lower sash. Each of the two parts composing our fastener consists
of two plates joined together, and situated in planes at right angles
to one another. One of the said plates is attached on the horizontal
face of the meeting bar, and the other plate (situated vertically) en-
gages, as herein-after explained, with the vertical plate of the other
and as the
part of the fastener when the sashes are nearly closed;
closing of the said sashes is completed, the said fastener draws the
same closely together, and secures them in that position. e, is the hori-
zontal plate of the part e, e¹. The said plate is attached by screws or
otherwise to the meeting bar f, of the lower sash. c¹, is the vertical
side of the said part e, e¹; the inner face e¹¹, of the said side being

page_text: inclined as seen in Figures 2, and 3; c, is the horizontal plate of the
part affixed to the meeting bar d, of the upper sash c¹, the vertical
side of the said part; the inner face c¹, of the said side being
inclined, as shewn in Figures 2, and 3. When the opened sashes
are moved (or one of them, as the case may be) in the direction
proper to close them, as soon as the meeting bars assume the relative
position represented in Figures 2, and 3, the inclined face e", of the
plate e, engages with the inclined face c¹¹, of the plate c', and as
the sashes close the two inclined faces c¹¹, e¹¹, come into contact. If
from imperfect construction of the window sashes, or otherwise, the
meeting bars d, f, do not come into contact with each other, as
shewn in Figures 2, and 3, on the closing of the said sashes, but
are separated from each other to any distance not exceeding the
width from g to h, Figure 3, then when the said sashes are closed
as far as is represented in Figures 2, and 3, the face e", of the
vertical plate e', engages with the face c¹¹, of the vertical plate c',
and on the further closing of the said sashes, the said inclined
faces bring the said sashes together by a clasping action, and hold
them tightly together so long as they are closed. The tongue i,
jointed to the part e, e¹, at k, secures the position of the sashes
after they are closed in the following manner: As the meeting bar f,
descends, the inclined face i¹, of the tongue i, coming in contact
with the shoulder l, on the plate c, c¹, is forced back in the direc-
tion indicated by the arrow in Figure 2, and the said motion
of the tongue i, is continued until the horizontal faces of the two
meeting bars are in the same horizontal plane, when the tongue i,
escapes under the shoulder I, and the edges i", 11 (see Figure 1),
engaging thereunder, the raising of the meeting bar f, is prevented.
By pressing the thumb plate m, in the direction indicated by the arrow
in Figure 2, the tongue i, may be disengaged from under the shoulder
1, and the bar f, may be raised. We sometimes modify our Invention
in the manner represented in plan in Figure 4, and in vertical section
in Figure 5. The said modification consists in substituting the bolt
n, for the tongue i, Figures 1, and 2, for fastening the sashes. The
said bolt is urged in the direction indicated by the arrow in Figure

page_text: 4, by the spring o, and the inclined edge n', of the said bolt acts with
regard to the angle l, of the plate c, c¹, Figure 2, exactly at the edge
i, of the tongue i, is herein described as acting with regard thereto.
By pressing upon the knob p, Figure 5, the bolt n, may be pressed
back, and the sashes separated. It is necessary that the point r, of
the plate e, e', Figures 2, and 3, do not project beyond the bevelled
edge of the meeting barf (see Figure 6), at the point s, and also
that the plate on the meeting bar d, do not project beyond the point
t, of the said meeting bar.
Figures 7, 8, 9, and 10, represent our Invention applied as a
fastening for such tablet as have tops supported by being jointed
to a pillar, and capable, when not in use, of being raised into a
vertical plane. Figure 9, represents in vertical section a portion
of a table to which our Invention is applied; u, is the top of the
table, and v, the block to which the said top is fastened. Figure
7, represents in perspective that portion of the fastening which is
affixed to the block v; and Figure 8, represents in perspective that
portion which is affixed to the table top u. The inclined or wedge
shaped surfaces w¹, w¹, engage with the surfaces x, x, and secure the
top u, firmly in its place. The position of the parts is fixed by the
bolt y, and spring z, shewn in the plan Figure 10. y, in Figure 8, re-
presents the end of the said bolt. Besides being used as a sash
fastener and a table fastener, our Invention may be used as a
fastener for other purposes.
Having now described the nature of our said Invention, and the
manner in which the same is to be performed, we wish it to be un-
derstood that we do not limit ourselves to the precise method of
currying our Invention into effect herein described, and represented
in the accompanying Drawing, as the same may be varied without
departing from the nature of our said Invention. But we claim
the construction of a fastener for fastening window sashes and
tables, and to be used for such other purposes as it is applicable
to, in which the two parts to be fastened are brought into their pro-
per relative position by inclined surfaces, and fastened by a bolt

page_text: or catch, as herein described, and represented in the accompanying
Drawing.
In witness whereof, we, the said William Westley and Richard
Bayliss, have hereunto set our hands and scals, this Thirteenth
day of June, in the year of our Lord One thousand eight
hundred and fifty-three.
Witness,
FRED. CAMPION.
