Complete Specification Left, 28th Aay, 1897-Accepted, 3rd July, 1897
I, SAMUEL BASTOW, of New Dock Saw Mills, Leeds, in the county of York, Timber
Merchant, do hereby declare the nature of this Invention to be as follows:-
The object of my invention is to construct movable windows or sashes, so as to be
weatherproof, and easily and readily cleaned from the inside, also opened and secured
in any position required, shaking and rattling being prevented.
In pivotted casement windows at the top and bottom of the sashe is provided a
groove or slot and also a shallow corresponding groove in the frame, within the slot in
the sash are two flat horizontal bolts with inclined slots in same. Fixed studs pass
through the slots, and a knob or handle is screwed into each horizontal bolt. To
secure the window the bolts at top and bottom are slid towards each side and also
downwards by reason of the inclined slots they work upon. They consequently enter
the groove in the frame and completely break the joint and again recede into the
groove in the sash when slid back. A thumb screw and striking plate are fixed near
the pivot, thus securing the sash in any open position required. In lieu of above the
bolts may be placed on the outside of the casement which is on the inside of the
window. Instead of the ordinary sliding sash windows the same principle of a pivotted
sash is adapted, only then the sliding pieces are used to break the joint vertically, one
bolt at each side of each sash being sufficient for that purpose.

I, SAMUEL BASTOw, of New Dock Saw Mills, Leeds, in the county of York, Timber
Merchant, 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:-
The object of my invention is to construct movable windows or sashes so that they
can be opened and secured in any required position, and can be easily cleaned from
the inside, the window when closed being quite weather-proof and free from all
shaking and rattling.

DESCRIPTION OF DRAWINGS.
Fig. 1 shows an elevation partly-in section, of my improved casement window with
single sash pivotted vertically
Fig. 2, is a plan of same with transome of frame removed to show the sash, which
is partly open.

page_text: Fig. 3 is a side view, in section, of Fig. 1.
Fig. 4, is an elevation of my improved double sash window, each sash being
pivotted horizontally.
Fig. 5 is a side view in section of Fig. 4, but shown with sashes partly open.
Fig. 6 is an enlarged sectional plan of one side of window in Fig 4, the section
being taken through top sash.
Fig. 7 is a section through line X Y of Fig. 5.
In Figs. 1, 2 and 3 the top and bottom rails A of the single sash window, pivotted
at B B, have a groove or recess B' in which are two flat horizontal bolts C.
Each one of these bolts C is held by means of two fixed screws D, D, which pass
through inclined slots E, E, in the bolt. These slots E, E, allow an inclined outward
movement being given to the bolts C, by means of a small knob F, which is screwed
into the bolt, and which works in an inclined slot G, in the sash rail A.
A groove or recess H, is provided in the frame J of the window, so that when the
knobs are moved outwards, the bolts Center the grooves or recesses H in the
frame (as shown at the bottom of Figs. 1 and 3), thus fastening the sash and
completely breaking the joints at top and bottom of sash, and making them entirely
weather-proof.
To prevent the lodging of water in the groove or recess H in the window sill, small
holes K, K, are bored in the sill.
To make the side joints weather-proof, a vertical beading L is put on the side rails
M of the sash, which beading L fits into a corresponding recess N in the frame.
The ends P P of the bolts C are only half thickness so as to overlap each other for
some distance, so that when the bolts are moved outwards, that is, in opposite
directions, the joint is broken continuously without leaving a space unprotected
between them.
For fixing the sash in any required open position, a pin and lever arrangement R
is fixed to the bottom rail of the sash, near the pivot, which pin engages with recesses
or holes S in a plate T fixed to the sill.
Or in place of these a thumb screw and striking plate, or other fastening
arrangement, may be employed.
As a further protection against the weather an overhanging weather guard U is
fixed outside the bottom rail of the sash.
In the double sash window (Figs. 4, 5, and 6) the recesses B₁ are made preferably
in the front of the side rails A of the sashes, which are pivotted horizontally at B B.
C are the flat bolts, which break the joints at the sides of the sashes, one
bolt at each side of each sash being sufficient for that purpose. D D are fixed
screws for securing the flat bolts C in position, and E, E, are the inclined slots in
the bolt C.
V is a small pin in the side rail A, fitting into a notch or recess W in the edge of
the bolt C, and H H are two grooves (one for each sash) in each side of the frame, so
that when the pin V is pulled outwards, the bolt C falls by its own weight and breaks
the joint by entering the vertical groove H.
A knob F is provided for pulling back the bolt and opening the sash.
The grooves Ĥ in the frame, or the edge of the bolts C, or both, may be tapered so as
to make a tighter and more weather proof joint, and the groove H with which the top
sash engages is continued to the bottom of the window to allow any water to
drain away.
A radially toothed or recessed plate or rack T is fixed to the frame at one side of
each sash, so that when the sash is opened, the pin V being out, the bolt C falls and
engages with the teeth or recesses in this rack or plate T, thus fixing the sash in any
required position.
In opening the window the side bolts C draw clear of the rack or plate T, thus
allowing the window to be turned inside out.
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 :—

page_text: 1. In vertically pivotted casement windows, breaking the joint and securing the
windows by means of sliding horizontal bolts and grooves for the purposes as
described.
2. In horizontally pivotted sash windows, breaking the joint and securing the
windows by means of sliding vertical bolts and grooves, for the purposes described.
3. In vertically pivotted casement windows horizontal bolts C in grooves B¹, screws
D, slots E, knob F, slot G in sash rail A, with recesses H in the frame of the window,
as and for the purposes substantially as shown and described.
4. In horizontally pivotted sash windows, vertical bolts C, in recesses B¹, bolts D,
and slots E, grooves H, with fixed toothed or recessed plates T, stop pins V, and
recesses W, as and for the purposes substantially as shown and described.
Dated this 27th day of May 1897.
