PROVISIONAL SPECIFICATION.
Improvements in Window-sash Fasteners.
We, ALEXANDER DAY and FRANK GREEN, trading as Day and Green of Great
Hampton Street Birmingham in the County of Warwick, Brass-founders, do hereby
declare the nature of this invention to be as follows:—
In such fasteners as ordinarily constructed, the fastening arms turn evenly in the
same plane upon a pivot, or joint centre directed through its inner end.
The object of our invention, is to construct the said arms, that they admit of being
adjusted vertically in respect of the pin or centre, upon which they turn; so that
should any difficulty arise in consequence of the tops of the meeting rails not coming
flush one with another, the arms can be made to change their planes.
In carrying out our invention, we take an ordinary attachment plate, with over-
hanging bracket on its inner side, and through a part thereof, which is pierced, the
neck of a bushed mount downwardly passes.
The inner end of the arm has an internally screwed sleeve, which is directed
upwardly from the inner end of the said arm, and fits accurately within the interior
of the mount as aforesaid, whilst through the mount and sleeve, a screwed pin
riveted to the plate at its lower end, and a knob or turn at its upper end, passes;
so that by rotating the said knob or turn in one or other direction, the arm is
vertically raised or lowered, and the necessary adjustment obtained.
Thus, if one of the sashes of a window fall, which is very common, the meeting
rails lie in dissimilar planes; so that in order to properly fasten the said rails, the
arm is adjusted higher or lower, so as to bring its underside in the plane.of the sash
carrying the drawing to or catch part.
Or an adjustment of the arm may be effected, by making it rise and fall upon a
plain pin, or upon a screw, and there kept in position by a screw nut, or by screw
nuts, taking upon the said axis or upon screwed collars of the arm.

Improvements in Window-sash Fasteners.
ALEXANDER DAY and FRANK GREEN of 105 Muntz Street Small-Heath
Birmingham in the County of Warwick, Brassfounders, 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 :-
In Sash Fasteners as ordinarily constructed the fastening arms turn evenly in the
same plane upon a pivot or joint centre directed through its inner end. The object of
our invention is to construct the said arms, that they admit of being adjusted vertically
in respect of the pin or centre E upon which they turn so that should any difficulty
arise in consequence of the tops of the meeting rails not coming flush one with
another the arin A can be made to change its plane. And when arm is brought
around on to quadrant by screwing down the knob the arm fits into slot in attachment
plate of quadrant so that by rotating knob not only is arm brought into proper
adjustmeut with bottom sash but also causes arm to effectually lock itself into slot.
In carrying out our invention, we take an ordinary attachment plate B with over-
hanging bracket C. on its inner side and through a part thereof which is pierced, the

page_text: neck of a bushed mount downwardly passes. The inner end of the arm has an
internally screwed sleeve D which is directed upwardly, from the inner end of the
said arm, and fits accurately within the interior of the mount as aforesaid, whilst
through the mount and sleeve a screwed pin E, rivetted to the plate at its lower end,
and a knob or turn at its upper end passes, so that by rotating the said knob or turn
in one or other direction, the arm is vertically raised or lowered and the necessary
adjustment obtained. Thus if one of the sashes of a window fall which is very
common, the meeting rails lie in dissimilar planes; so that in order to properly
fasten the said rails, the arm is adjusted higher or lower so as to bring its underside
in the plane of the sash allowing the arm or catch to pass.
Or an adjustment of the arm may be effected by making it rise and fall upon a
plain pin, or upon a screw, and there kept in position by a screw nut or screw nuts
working upon the said axis or upon screwed collars of the arm.
And in order that our Invention may be clearly understood, we hereunto append
an explanatory sheet of Drawings.

Locked.
Fig. 1 represents the sashes as they should be, namely level, in which case our
invention can be used as an ordinary fastener with the advantage of being able by
rotating knob E to lock bar A into slot G.
Fig. 2 shows sashes with top sash fallen in which case by rotating knob E the
arm A is raised to the plain of bottom sash and thus easily passes over same with the
same advantage as to locking as in Fig. 1.
Fig. 3 shows slot as formed in quadrant attachment piece.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1st. Improvements in Sashfasteners having vertically adjustable arm.
2nd. Locking slot formed in quadrant attachment plate used in combination with
vertically adjustable arm substantially as hereinbefore described and shown on
accompanying sheet of drawings.
