Improvements in Window and other Fasteners.
1, WILLIAM DE COURCY PRIDEAUX 5 Fore Street Wellington in the County of
Somerset Ironmonger do hereby declare the nature of this invention to be as
follows:-
-
The device of which this Patent is an object is for the more effectual and secure
closing of window sashes casements, hutches, doors, hoxes, shutters and such fastenings
as are used in garments and other articles such as leggings, boots, and generally
wherever fastenings are required.
In carrying out my invention I use steel wire or any other flexible or springy metal
or material which may be adapted for the purpose of this invention. The shape is
somewhat like that of two capital letters V placed apex to apex at the point where
the apices meet & greater strength is required the wire may be twisted upon itself
or in any other way joined or if not joined, brought together in a permanent manner
or can be left open or nearly approximating to each other the open or broad end of
one of the Vs is joined by the wire and this forms part of a hinge joint or other
arrangement for lifting the fastener and keeping it ont of the way when the window
sashes casements hutches doors boxes or shutters are intended to be opened or closed.
The other V has its ends left open and free and if the material is elastic enough forms
a spring of itself, if not elastic enough supplimentary or auxiliary springs can be
used which may be kept either in a state of compression or tension ns desired.
The free end of one of the Vs or the open ends when the ends are left open or nearly
approximating to each other, engages with a catch which overlaps the extended part
of the V and is placed on one of the sashes or the fixed parts respectively of the sash
door frame or any parts it is desired to close, and this catch may be made of elastic
or springy material or may have auxiliary springs to supply the required elasticity
to the parts that overlap the wire or hinged moveable part so that in the case where
the hinged part is inelastic and stiff the catch may be made sufficiently springy as to
act as a spring and retain the hinged part securely in its place.
The hinged part may also have loops or eyes for attaching padlocks or labels to.

Improvements in Window and other Fasteners.
WILLIAM DE COUROY PRIDEAUX 5 Fore Street Wellington Somerset Ironmonger
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 has reference to an improvement in the method of making fasteners
catches or similar devices that are used for closing or keeping in certain fixed positions
window sashes casements lids of boxes and cases the mouths of bags or in fact may be
applied to any article where it is desired to attach fasteners.
carry my invention into practice by shaping wire rod or sheet metal of any
required size or sections into certain forms most desireable for the purposes to be
hereinafter described and shown in the drawings annexed hereto in the which are
shown various patterns or designs which such wire rod or sheet metal may assume and
which will hereinafter for the sake of brevity be called the hasp which is formed

page_text: somewhat in a horse-shoe or dovetail shape having two or more free ends at liberty to
be expanded or contracted at will and tending after they are released from such
expansion or contraction to resume their normal shape.
The hasp is attached either fixedly or in a manner free to move in certain directions
to a plate which will be hereinafter for the sake of brevity called the hasp-plate
instead however of having a hasp-plate the hasp can be made to move in staples or
similar devices.
Where a hasp-plate is used the hasp is attached to it by means of a sleeve or
wrapping round the hasp a portion of the metal composing the hasp-plate this part
of the hasp-plate will be hereinafter called the hasp-sleeve.
That part of the hasp in the case where the hasp is made moveable in the hasp-
sleeve may be male curved or bent so that when moved in certain directions it shall
press harder against one part or parts of the inside of the hasp-sleeve than it shall
at other parts, in the case where the hasp is attached to the hasp-plate, the hasp-plate
is attached or fixed to a certain part of the article upon which it is desired to use
the fastener by screws rivets nails solder or any of the usual well known methods
suitable for attaching one article to another.
In the case where the hasp is fixed to the article to which it is desired to use the
fastener for by means of staples or similar devices these staples or other devices are
attached to the article by driving or screwing or other well known methods of
fastening such staples or other devices.
Instead of the asp being made of springy metal it may be made of non springy
inetal and may have the necessary elasticity to constitute it a spring given to it by
auxiliary or other springs and the hasp may even be made of non elastic metal in
which case the part into which the hasp fastens hereinafter called for the sake of
brevity and clearness the catch may be made elastic or springy so as when the inelastic
hasp is placed in a certain predetermined position the elasticity of the catch will keep
it in that position until it is released at will.
As has been stated the catch is that part of the fastener which keeps the hasp in
a certain definite position. The catch may be formed of sheet metal or wire bent
into certain shapes shown on the drawings annexed hereto, the said sheet metal or
wire may be of tempered elastic metal or untempered or inelastic metal or the catch
may be made of nails tacks or screws with various shaped heads or projections
composed of wood metal or any other suitable material.
The catch when it is composed of sheet metal or wire may be attached to the
article which it is desired to use the fastener for by means of screws rivets solder or
other well known methods of fastening and when screws nails or tacks are used as the
catch they may be driven or screwed in or fixed to the article to which it is desired
to attach the fastener to by any of the usual and well known methods.
The method of using this fastener is generally as follows ;-
The hasp-plate being attached say for example to the hinged cover of a box and
the catch being attached to the body of the box in a suitable position relative to the
hasp the free ends of the hasp are compressed or extended as the case may be and
placed whilst compressed or extended in a certain position with reference to the
catch and then allowed to assume their normal state when the cover will be closed
upon the body of the box.
To unfasten the cover of the box the free ends of the hasp are either compressed or
extended and this disengages it from the catch and thus allows the cover of the box
to be opened. In the case where the hasp is fixed in the sleeve of the hasp plate the
catch is so shaped and also the free ends of the hasp are so formed that upon a part
of the basp passing a fixed point in the catch the lasp springs into a position which
fastens the cover and body of the box together.
In order that the carrying out of my invention into practice may be more clearly
understood have illustrated it on the accompanying one sheet of explanatory
drawings and have marked the same with letters of reference corresponding with those
given in the following description thereof. .

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a fastener of which A. B. is the basp-plate, the part B being
the sleeve through which the hasp C. F. is passed F being the free end which may
terminate in a scroll as F in Figure 3 or bent up as F N in Figure 8 or splayed out
as H. F. in Figure 2 or may assume any of the other shapes given to the free ends
as shown in the sheet of explanatory drawings that may be considered desirable or
suitable. E. D. in Figure 1 is the catch which is composed of a piece of sheet metal
and the sides D are curved in a semi-circular or any other suitable manner to allow
the parts of the hasp immediately preceding the free ends to be overlapped so that
when the free ends F are drawn towards each other they are brought clear of the
overlapping edges D of the catch E and so released from the catch. If the husp C. F.
is not free to move in the hasp-sleove B upon closing the article to which the husp:
plate is attached the part F of the hasp C. F. slides over the inclined part V of the
hasp and also the parallel or inclined or other suitable formed edge W and springs
into its place under the turned up edge D as soon as the free end is clear of the turned
up edge thus formning a snap-catch fastener to release the catch the free ends F must
be brought together and the part to which either the hasp-plate or the catch is
attached pulled apart.
Figure 2. shows another form of hasp C. F at the part G the hasp is bent inwards
and the ends H. F. are splayed outwards.
Figure 3 shows a side view of hasp and hasp plate in which at the part C of the
hasp it is curved or bent in order to give the hasp C. Felasticity in the saine direction
as that in which the hasp moves when, it is free to move in the hasp sleeve or by
means of such curves or bends to form a spring tangential or radial to a circle
discribed by any part of the hasp having as its centre that part of the basp passing
through the hasp sleeve.
Figure 4. shows the hasp bent at K for the purpose of accomodating itself to any
special form of article to which it may be attached.
Figure 5. shows the hasp crossed upon itself at G by which arrangement upon
compressing the free ends F the catch is released from the looped wire fastener shown
in Figure 13 in which represents a section of the hasp, Y the looped fastener,
X the screws for attaching the loop wire catch to the article to be fastened.
Figure 6. represents a fastener in which the hasp C is coiled upon itself at M.
Figure 7, is another form of fastener in which the hasp iminediately it emerges
from the two sides of the hasp sleeve B is coiled into loops L to give it additional
elasticity and strength.
Figure 8. shows the method of turning up the free ends adopted in the fastener
shown in Figure 7.
Figure 9. shows a fastener in which the basp is shaped same as described under
description of Figure 2 but in addition has a middle finger U terminating in a
loop which fits over a staple or its equivalent O through which staplo a padlock
or any other locking arrangement inay he passed.
Figure 10 is the same arrangement almost as described under Figure 9 it has a
middle finger U which terminates in a.hook or curve P¹ a side view of this is
shown in Figure 12 in which P¹ shows the hook or curve and Z the knob over
which it fits.
Figure 11 is much the same form of fastening as described under description of
Figure 10 but the middle finger terminates in a book or rectangular bend S which
passes into an aperture T of the catch E. D.
The object to be obtained by the adoption of fingers as described under Figures 10
and 11 is for greater security and for resisting strains tending to pull open the
fastener.
This invention has no similarity to "pinch-cocks" which is an old and well known
device used by chemists and physicists in laboratories or for scientific and other
SARAN

page_text: Having thus 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
claim is,
1. I claim the shaping of the hasp with two or more free ends in such a way that
upon being put in certain given positions and released from a state of tension or
compression it will tend in resuming its normal position to assume one in relation to
certain projections or depressions as will fix or fasten the parts to which the hasp
and catch are respectively attached.
2. I claim the shaping of the hasp as described or any combination of shapes or
parts of the hasp as described or herein before set forth.
3. I claim the shaping of the free ends and parts immediately preceding the free
ends of the hasp in the manner hereinbefore described.
4. I claim making the catch of springy or rigid metal when applied to any of
theso forms of fasteners herein before described.
5. I claim the combination of any of the part or parts of any one fastener herein-
before described with the part or parts of any other fastener hereinbefore described
that may be suitable for the purpose of a fastener to act in the method as hereinbefore
described.
6. I claim curving the hasp in any other plane other than and in addition to the
plane along which the free ends act with the object of giving the hasp additional
elasticity for other fastening purposes than that needed for engaging the free ends
with the catch as hereinbefore explained.
