An Improved Fastener for Windows, Cupboards, and the like.
Year: 1898

page_text: An Improved Fastener for Windows, Cupboards, and the like.
I, WILLIAM ROWE, of View Cottage, Sun Road, Gravesend, Kent, Commercial
Traveller, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in fasteners for windows cupboards and
the like, and has for its object the provision of a fastener that cannot be manipu-
lated or tampered with from the outside of a window, or by the insertion of any
lever or tool between the upper and lower sashes of a window frame.
This improved fastener is formed in the following manner:-The upper or
outer sash is provided with a metal plate having on its upper surface a thickness
of metal, segmental in shape on plan, and surmounted by a flange of the same
shape, but of enlarged diameter, thus forming a semicircular grooved flange on
the aforesaid plate. The portion attached to the other, or lower and inner sash,
likewise consists of a metal plate, on the upper surface of which is provided a
semicircular strip or ridge which forms the space in which the fastener revolves.
This fastener consists of a semi-circular disc, grooved out integrally on its under
surface, so as to fit and revolve or slide over the segmental shaped provision on
the upper or outer sash aforesaid. At one end of this disc is fixed a lug or plate
forming a thumb piece for the purpose of revolving the disc.
This said fastener revolves on a pin fixed on to the metal plate, and also to a
cover plate fixed over the revolving fastener, which said cover plate is screwed
on to two lugs one at each opposite side of the plate. The under surface of this
said cover plate is provided with a semicircular strip or ridge, exactly correspond-
ing to the similar provision on the lower plate aforesaid, which is fixed on to the
sash, so that when the two plates are screwed together, they form a grooved semi-
circular channel, in which the fastener revolves, the space between the surface
of the ridge of the upper cover plate, and that of the lower sash plate, providing
a channel or groove, between which the aforesaid thumb plate travels, in opening
and closing the fastener.
When the fastener is open, the flat or diametrical surface of the revolving semi-
circular disc faces the edge of the sash, so that the sashes are free to move up or
down, but by using the aforesaid thumb lug or plate, and pushing it round in the
channel aforesaid, the grooved portion of the disc travels over the flanged disc
on the outer sash plate aforesaid, and the circumferential portion of the revolving
disc is presented outwardly and the fastener is closed.
This improved fastener may be applied to cupboard and other doors or any
similar appliance requiring to be fastened.

page_text: I, WILLIAM ROWE, of View Cottage, Sun Road, Gravesend, Kent, Commercial
Traveller, 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 fasteners for windows, cupboards, and
the like, and has for its object the provision of a fastener that cannot be manipu-
lated or tampered with from the outside of a window, or by the insertion of any
lever or tool between the upper and lower sashes of a window frame.
This improved fastener is formed in the following manner -The upper or
outer sash (in the case of the usual sliding window sashes) is provided with a
metal plate having on its upper surface a thickness of metal, segmental in shape
or plan, and surmounted by a flange of the same shape, but of enlarged diameter,
thus forming a semicircular grooved flange on the aforesaid plate. The other,
or lower and inner sash, is likewise provided with a metal plate, on the upper sur-
face of which is a semicircular strip or ridge which forms the space in which the
fastener revolves.
This said fastener consists of a semicircular disc, grooved out internally on its
under surface, so as to fit and revolve or slide over the segmental shaped pro-
vision on the upper or outer sash aforesaid."
At one end of this disc is fixed a lug or plate forming a thumb piece for the
purpose of revolving the disc, or if more convenient as in the case of a cupboard
fastener and the like the thumb piece may be on the upper portion of the semi-
circular disc and continued through the covering plate, so as to be worked from
the flat side of the fastener.
This said fastener revolves on a pin fixed on to the metal plate, and also to a
cover plate fixed over the revolving fastener, which said cover plate is screwed
on to two lugs, one at each opposite side of the plate. The under side of this said
cover plate is provided with a semicircular strip or ridge, exactly corresponding to
the similar provision on the lower plate aforesaid which is fixed on to the sash
so that when the two plates are screwed together they form a grooved semi circular
channel, in which the fastener revolves, the space between the surface of the ridge
of the upper cover plate, and that of the lower sash plate, providing a channel
or groove, between which the aforesaid thumb plate travels, in opening and closing
the fastener.
When the fastener is open, the flat or diametrical surface of the revolving semi-
circular disc faces the edge of the sash, so that the sashes are free to move up
and down, but by using the aforesaid thumb piece or plate, to cause the disc to
revolve in the manner described, the grooved portion of the said disc travels over
the flanged disc on the outer sash aforesaid, and the circumferential portion of
the revolving disc is presented outwardly and the fastener is closed. If preferred
more than one flange can be provided on the segmental portion of the fastener,
and a corresponding number of grooves on the other or inner sash portion of the
fastener, the advantage of this arrangement being, that in the event of the two
sashes not being quite closed one of the grooves can be made to fit on to and slide
over the flange which may be opposite to it, so that the fastener may be closed
without the necessity of the groove being made to revolve over and on its proper
flange.
Reference has been made in the foregoing description to the improved fastener
as applied to window sashes, but this said fastener may be applied to cupboard or
other doors or any similar appliance requiring to be fastened.

page_text: In order that this invention may be readily understood reference is made to
the accompanying drawings in which Fig. 1, represents a plan of the improved
fastener, Fig. 2, an end elevation of the same, Fig. 3, a longitudinal elevation of
the outer or segmental portion, Fig. 4, a longitudinal elevation of the disc or inner
portion of the fastener, Fig. 5, is again longitudinal elevation of the outer or
segmental portion, having more than one flange, Fig. 6, an elevation of the disc
or inner portion with a corresponding arrangement of grooves and Fig. 7, an end
elevation of the fastener shewing how the grooves and flanges may be used when the
window sash is not tightly closed. In these several views A is the outer window
sash, B the inner sash, CC are the plates of the improved fastener for screwing
to the window sashes, D the segmental portion with the flange or flanges E. F is
the semicircular disc with the lower portion flanged at G, forming the groove or
grooves H, the said disc revolving between ridges J J, on the pin K, the upper
ridge being part of the cover plate L screwed on to the main body of the sash
fastener by means of screws M M to the lugs N N. O is a lug or thumb plate
for revolving the disc, or if preferred the motion can be effected by means of
the thumb piece shewn in dotted lines at P. The position of the disc when
closed is shewn by dotted lines at Q.
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. The provision of a fastener for windows, cupboards, and the like, having a
semicircular grooved disc, revolving between plates, and sliding over a segmental
flanged thickness of metal substantially as and for the purpose herein set forth
and described and illustrated by the accompanying drawings.
2. The application of this invention to any kind of window sash, cupboard door
or like appliance, substantially as and for the purpose herein set forth and
described and illustrated by the accompanying drawings.
