COMPLETE SPECIFICATION.
"An Improved Fastener for Window Sashes and for other like
purposes."
I, ANTHONY HODGSON-BROWN, 3, Aston Terrace, Cockerton, Darlington, Musician
do hereby declare the nature of this invention and in what manner the same is to
he performed, to be particularly described and ascertained in and by the following
statement:
My invention relates to an improved fastener for window sashes and for other
like purposes, the object being to obviate the use of springs, and to prevent opening
except by operation from within the room or apartment.
In order to more clearly define my invention, I will make reference to the
accompanying sheet of drawings, in which Fig. 1, is a plan, and Fig. 2, a sectional
side view. Similar letters denote the same parts wherever they occur. and bare
respectively the inner and outer sashes. To b is attached the base-plate e over
which is free to move the ring & having the stem e crossing from one sash to the
other and provided at one end with a hook f to embrace the headed ping attached
to a. Working in is the flange of the milled edge disc i which can be turned
on the eccentrically placed pin j, the lower end of which screws in the internally
threaded lug on c. The hole in i is sufficiently large to permit i to move freely
round the pin j, having the head and shoulder 7. When is put in the required
position to fasten the sashes a and b, jis screwed down thus causing to press on i
and keep from moving. A stop m is provided on a to prevent i being turned in
the wrong direction. As a substitute for the milled edge to i, I might employ a
projecting finger-piece as shown in dotted lines at n.
In use, assuming the hook f to be embracing g, and so locking the sashes, then
on slightly unscrewing and turning in the direction of the arrows, the flange h
acting eccentrically within 7 will move f from 9 and thus allow the sash to he
opened. The reverse movement, and final screwing down of j will fasten the
sashes.
Although I have described and shown the invention as applicable to the fasten-
ing of two window sashes, it may nevertheless be used for any similar purpose, for
instance, as a latch, the parts a b representing in that case part of the door and
part of the frame surrounding it.
I do not confine myself to the precise shapes and configurations, or the relative
proportions or dispositions of parts shown in the drawings or described in the abovu
specification, as any or all of them are capable of some modification without
departure from the spirit of my invention.
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 claini
is:-

page_text: parts to be fastened together, over which plate is free to move a ring having
attached thereto or formed therewith a stem of such length as to extend fully from
one sash or part to the other sash or part, the said stem terminating in a hook.
capable of embracing a headed pin or projection attached to the second sash or
part, the said ring being moved for opening or closing the fastener by means of an
eccentrically movable disc or ring, the pin on which it is movable passing down-
wards within the ring bearing the stem already mentioned, the pin being capable
of screwing down into the base plate or a lug thereon for the purpose of keeping
the fastener closed, a suitable stop being also provided on the base plate to prevent
the above mentioned ring and stem from being turned in the wrong direction, the
whole substantially as described in the above specification and exemplified in the
accompanying drawing.
2. An improved fastener for window sashes and for other like purposes, the said
fastener being constructed and operating substantially as described in the above
specification and exemplified in the accompanying drawing.
