IMPROVEMENTS IN SASH FASTENERS
Year: 1885

Holborn London Merchant and FRANKLIN T. DAVIS of Eastchester in the State
of New York United States of America do hereby declare the nature of our said
invention for IMPROVEMENTS IN SASH FASTENERS to be as follows':
This Invention relates to fasteners for securing the meeting rails or frames of
windows.
According to this invention one of the frames is provided with a plate (preferably
provided with a central recess or hole) from the outer edge of which rises a hook
or curved projecting piece. The second frame is provided with a plate, from the
outer edge of which rises an arm carrying a truncated wedge shaped catch beneath
the inner portion of which is pivoted to the base plate a slightly curved two armed
piece which when closed down is adapted to just pass over the hook or curved pro-
jecting piece upon the plate on the first named frame. The two armed piece is
acted on by a spring, the constant tendency of which is to keep it down. Pivoted
between the arms is a catch of somewhat the same section as a bridge rail with
one side slightly longer and straighter than the other, and it is through this arm
that the pivot is placed, the projecting portion of the arm on the pivot side passing
into the central recess or hole in the first named plate, when the two arm piece is
down, while the face of the rail section catch farthest from the pivot is then beneath
or approximately against the inner side of the truncated wedge shaped catch upon
the second plate. After being once closed it is impossible to raise the two arm
piece, and open the window without also raising the pivoted catch but when this
has been done, and the two arm piece fully raised, the pivoted catch will engage
with the truncated wedge shaped catch and hold the two armed piece up so that
the window may be freely opened. As the window is subsequently closed the edge
of the first plate strikes against the long arm of the bridge rail section catch which
is thereby disengaged from the truncated wedge shaped catch, and the spring forces
the two armed piece down the hook or projecting piece on the first plate striking
the bridge rail sectioned catch, and so turning it on its pivot that it again passes
beneath or against the inner face of the truncated wedge shaped catch. Thus the
simple closing of the window is sufficient to automatically lock it.

Applicants' Agent,

page_text: We, AUGUSTUS PEARCE ROCKWELL, temporarily of the First Avenue Hotel,
Holborn London, Merchant, and FRANKLIN T. DAVIS of Eastchester in the State
of New York, United States of America, 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 fasteners for securing the meeting rails or frames of
windows and to clearly explain the invention reference is made to the accompanying
drawings which form part of this specification and in which—
Fig. 1 represents a plan view of the fastener as applied to the sashes or frames.
Fig. 2 represents an elevation of the same, the window being closed.
Fig. 3 represents the parts as they appear when the window is open.
The same letters of reference indicate like parts in the various figures.
According to this invention the upper bar "a" of frame A is provided with a
plate d (preferably provided with a central recess or hole) from the outer edge of
which rises a hook or curved projecting piece c.
The lower bar e of the second
frame B is provided with a plate g from the outer edge of which rises an arm
carrying a truncated wedge or other shaped catch f beneath the inner portion of
which is pivoted in lugs g¹ g¹ to the base plate g, a slightly curved two armed piece
or hasp h which when closed down is adapted to just pass over the hook or curved
projecting piece c upon the plate on the frame A. The two armed piece h is acted
on by a spring i, the constant tendency of which is to keep it down. Pivoted
at k between the arms of h is a catch or locking dog j of somewhat the same
section as a bridge rail with one side slightly longer and straighter than the other,
and it is through this arm that the pivot k is placed, the projecting portion of the
arm on the pivot side passing into a central recess or hole or under the projection c
in the plate d when the two arm piece h is down, while the face of the rail section
catch, farthest from the pivot.as at 1, A, is then beneath or approximately against
the inner side of the wedge shaped catch f as at m, m³ upon the second plate g.
After being once closed it is impossible to raise the two arm piece h, and open
the window without also raising the pivoted catch j, but when this has been done,
and the two arm piece h fully raised, the pivoted catch j will engage with the
wedge shaped catch by means of projections / m² and hold the two armed piece h up
so that the window may be freely opened. As the window is subsequently closed
the edge d¹ of the plate d strikes against the arm 12 of the catch j which thereby
disengages ¹, m², and the spring i forces the two armed piece h down, the hook
or projecting piece c on the plate d striking the catch; at j¹ and so turning it on
its pivot that it again passes beneath or against the inner face of the wedge shaped
catch f. A slight recess n is cut in the upper bar a of the lower sash A to form a
clearance for the arm of the catch j, so that it will not be operated in closing the
sash until the edge d¹ of plate d is reached. In case the sash is not entirely closed
the projection on the catch; will engage with the upper projection m of the
catch and effectually lock the sash so that the entire fastener is very effective

page_text: and reliable and requires no attention when locking the window. Thus the simple
closing of the window is sufficient to automatically lock it.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is-
1st The sash fastener herein shown and described, which consists of the hook c,
and projecting lip , attached to the lower sash, the catch attached to the upper
sash, in combination with the hasp h and catch j, pivoted therein, substantially
as set forth.
2nd The catch f, formed with shoulder m², in combination with hasp h, and
catch j, formed with stud l¹ for holding the hasp and catch j in vertical position
substantially as described.
3rd The hasp h in combination with catch ;, having projection and catch ƒ,
having shoulder m² substantially as and for the purposes set forth.
4th The catch f, formed with projections m m³, in combination with the hasp h,
and catch, pivoted therein and formed with projections 1, 1, substantially as and
for the purposes set forth.
.
5th The combination, with the plate g having catch f, and lugs g¹, g¹, of the
hasp h, catch j; and spring i, as set forth.
