Improvements in Bolts and Fastenings for Windows and other
purposes.
We, FRANK RANDOLPH MULLINGS PHELPS, and THE SIMPLEX WINDOW
FITTINGS COMPANY LIMITED, both of 63 Temple Row, in the City of
Birmingham, Manufacturers, do hereby declare the nature of this invention to
be as follows:-
This invention relates to fastenings for application to windows where it is
necessary to secure the sash in any desired position by means of a spring catch
engaging with a rack or series of holes formed in a plate upon the window, the
object of the invention being to produce a fastening which shall have no projecting
manipulating stud or other device which shall cause inconvenience in operating and
be liable to be accidentally displaced or damaged by reason of the projection
formed upon it. Our improved fastening or catch is also suitable for securing
drawers, doors, and other portions of a moving framework where it is convenient to
have a flush sliding bolt or catch which will not project beyond the surface of the
door frame or other article to which it is secured.
In carrying our invention into effect we construct our fastening as a sliding catch
in one convenient manner, by. making a frame plate or carrier with an opening or
recess in the upper face and another opening or hole formed in the side face, the
side opening or hole being. for the bolt and the front opening for the manipulating
slide piece. We make our bolt with its projecting tongue for engaging in the
staple or catch of any desired shape, square, round or of other form, and we form
it preferably with a flat inner tail piece carrying a spring or springs behind it
which serve to force out the catch when a thumb piece is liberated. We make this
tail piece sometimes with a pair of bosses or ears having holes within them to slide
upon pins or a pin passing from one edge of the frame to the other, and around
these guide bolts or bolt pins we place the thrusting springs. We sometimes make
a guide projecting piece upon the end. plate of the catch which carries the pins for
the purpose of keeping the slide tail of the bolt in position.
On the slide tail we mount a peculiarly formed lever having a rocking motion
preferably which enables one end to rise up and engage with the front end of the
slot or channel formed upon the face of the bolt frame and when this end or
projecting portion of the manipulating finger piece is up against the edge of the
channel the bolt is kept right back unlocked, but when the plate or rocking piece
is depressed and allowed to be free from the end of the channel or groove then the
springs or spring carries forward the bolt and thus causes it to lock and become
engaged in the stop.
The rocking action of our finger piece we vary by arranging sometimes a spring
beneath the tongue piece which will prevent the accidental release of the tongue
piece occurring. We fashion the manipulating end of the tongue piece into any
suitable form convenient for liberating the end from the bar of the groove, and we
sometimes make a button like projection upon the rocking tail so that it may be the
more readily thrust in.
We modify the shape and configuration of our bolt case and the method of
mounting our rocking tongue piece and the form of the channel and groove,
together. with the shape and arrangement of the tail and the springs to suit the

page_text: form of Stting, door, lift casement, window sash, drawer or other article to
which it may be necessary or desirable to attach our improved form of flush
catch bolt.

Improvements in Bolts and Fastenings for Windows and other
purposes.
We, FRANK RANDOLPH MULLINGS PHELPS, and THE SIMPLEX WINDOW
FITTINGS COMPANY LIMITED, both of 63, Temple Row, in the City of
Birmingham, Manufacturers, 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 fastenings for application to windows where it is
necessary to secure the sash in any desired position by means of a spring catch
engaging with a rack or series of holes formed in a plate upon the window, the
object of the invention being to produce a fastening which shall have no projecting
manipulating stud or other device which shall cause inconvenience in operating and
be liable to be accidentally displaced or damaged by reason of the projection formed
upon it.
Our improved fastening or catch is also suitable for securing drawers,
doors, and other portions of a moving framework where it is convenient to have a
flush sliding bolt or catch which will not project beyond the surface of the door
frame or other article to which it is secured.
In the accompanying sheet of explanatory drawings,
Figure 1 is a sectional elevation of our catch or spring bolt;
Figure 2 is a reverse plan; and Figure 3 is a sectional end view of the same.
In carrying our invention into effect we construct our fastening as a sliding catch
in one convenient manner, as shown in Figures 1, 2 and 3, by making a frame plate
or carrier A with an opening or recess B, in the upper face, and another opening
or hole C formed in the side face, the side opening or hole being for the bolt D, and
the front opening for the manipulating slide piece E. We make our bolt D with
its projecting tongue d, for engaging in the staple or catch of any desired shape,
square, round, or of other form, and we form it preferably with a flat inner tail
piece D, and carrying a spring F or springs behind it which serve to force out the
catch when a thumb piece E' is liberated. We make this tail piece sometimes with
a boss D2, or pair of bosses or ears having a hole or holes within them to slide upon
pins or a pin G passing from one end of the frame A to the other, and around the
guide bolts or pin G, we place the thrusting spring F. We sometimes make a guide
projecting piece upon the end plate of the catch which carries the pins for the
purpose of keeping the slide tail of the bolt in position.
On the slide tail we mount a peculiarly formed lever E having a rocking motion
preferably which enables one end E to rise up and engage with the front end of the
slot or channel B formed upon the face of the bolt frame and when this end
or projecting portion E of the manipulating finger piece is up against the edge of
the channel as in Figure 1 the bolt is kept right back unlocked but when the plate
or rocking piece is depressed and allowed to be free from the end of the channel or
groove B then the springs or spring F carries forward the bolt and thus causes it
to lock and become engaged in the step.
The rocking action of our finger piece we vary by arranging sometimes a spring
beneath the tongue piece E which will prevent the accidental release of the tongue

page_text: piece occurring. We fashion the manipulating end E of the tongue piece into any
suitable form convenient for liberating the end from the bar of the groove B and we
sometimes make a button like projection upon the rocking tail so that it may be the-
more readily thrust in.
We modify the shape and configuration of our bolt case and the method of
mounting our rocking tongue piece and the form of the channel or groove together
with the shape and arrangement of the tail and the springs to suit the form
of fitting, door, lift casement, window sash, drawer or other article to which it may
be necessary or desirable to attach our improved form of flush catch bolt.
Having now particularly described and ascertained the nature of our said inven-.
tion and in what manner the same is to be described, we declare that what we
claim is;-
1. The construction and arrangement of sliding bolts or catches substantially as
and for the purposes hereinbefore described and as illustrated in the accompanying
drawings.
2. In a sliding catch or bolt the construction and arrangement of a depressing
manipulating lever for releasing and for securing the bolt substantially as and for
the purposes hereinbefore described and as illustrated in the accompanying
drawings.
