Improvements in Bolts or Fasteners for Doors, Windows, and
the like.
We, HORATIO SAQUI, of 29 & 30 Liverpool Street, in the City of London,
Jeweller ERNST JAHNCKE, of Canonbury Works, Dorset Street, Essex Road, in
the County of Middlesex, Metallic Box Manufacturer, and THE "FUTURE" BOLT
SYNDICATE, LIMITED, of 17 & 18 Telegraph Street, Moorgate Street, in the
City of London, do hereby declare the nature of the said invention to be as
follows:-
This invention relates to a fastener for doors of various kinds such as house
doors, railway-carriage doors, cabin-doors, and the liko, aud also window sashes
and the like, and is so dosigned that it may be used as a bolt for entirely fastening
the door close or may be employed for the same purpose as the well-known door
chain which allows the door to be opened to a certain extent but no further.
In carrying the invention as applied to doors into effect we prefer to employ a
slotted yoke the pivotted end of which is by preference adapted to act as a spring
catch upon the well-known principle of the pocket articles such as cork-screws,
the effect being that the spring has a tendency to keep the yoke in a certain
angular position, but that the yoke can nevertheless be moved into other positions
as required. Any other suitable form of spring or spring catch may however if
preferred be employed for this purpose. The bracket to which the yoke is pivotted
may be secured upon the door or window frame or the like; this bracket is
preferably in two portions one fixed and the other pivotted so as to allow the
alotted yoke to be turned preferably a limited distauce only. Upon the door or
sash is socured a suitable bracket ontch or equivalent which may consist of a flat
plate having a headed projection extending towards the pivot of the yoke. Upon
the plate is pivotted a cam button having a projection or handle by which it may
be turned preferably to the extent only of about a quarter of a revolution. The
action of this apparatus is as follows:-
The door being closed, but not locked, the slotted yoke is turned upon its pivot
and pressed upon the cam-button so as to turn it upon its centre and raise the
projection or handle into a line with the slot of the yoke in consequence of which
the yoke can be passed over the button which then being overbalanced turns upon
its centre and locks the yoke in position. To release the door tho cam-button must
be turned by the operator upon its centre and hold while the yoke is removed when
the door can be opened.
If however it be desired, while releasing the com-button and absolute bolt, not to
allow the door to be entirely opened the slotted yoke -is opened to the point at
which its spring causes it to rest. It then lies inside of or against the head of the
bracket plate of the door. The slot of the yoke itself is cularged at the pivot end
to allow of that portion of the yoko passing freely over the head of the bracket
plate. The door being closed and the yoke in the described position if the door
be opened the door itself will press against the yoke and turn it further upon its
pivot as the door opens, but the door will only be able to open so far as the bracket-
plate can slide in the yoke, the slot of which prevents the head from slipping off
the plate. The operation of this part is similar to that of the well-known door
chain. To open the door entirely the yoke must, while the door is closed, bo
turned so far open as to prevent the head of the bracket plate locking itself in the
yoke in the manner previously described. The spring of the yoke prevents it
from swinging backwards and forwards and excepting for its one normal point it
romaine where it is placed

page_text: As it is sometimes desired to place this apparatus upon the outside of a door,
say a street door, it is desirable to be so able to fasten or lock it that it cannot be
tampered with, and also to so arrange it that the screws by which the parts are
held to the door or framework cannot be removed until the apparatus is opened.
For this purpose we provide means of looking the parts which may be effected in
various ways. For example a hole may be made through the cam-button in any
required part and through this hole a padlock may be placed so that even if the
cam bo turned the yoke cannot be lifted and the fastening is thus maintained. Or
one or more loops may be provided in any required manner and at any required
part or parts upon the bracket-plate and the padlock placed through as before.
Or, again, a lock may be placed within the button or locking plate in such a
manner as to secure the parts, when the lock is placed in the cam it may be
arranged to operate by preventing the cam from being turned at all.
By securing the bracket-plate by screws passing through lugs extending there-
from tho lock may be arranged to cover these screws so that they cannot he got at
until the yoke is lifted which cannot be done whon the apparatus is locked.
Similarly the screws holding the yoke bracket upon the frame may be arranged so
as to be covered by the yoke or other portion of the apparatus. The scrows
however may be otherwise placed or arranged so long as they are protected when
the apparatus is closed.
To secure the screws on the bracket-plate from being withdrawn when the yoke
is lifted we provide means whereby they are protected and we may preferably
employ lugs in such position on the bracket-plate with relation to loops thereon or
to a hole or holes in the cam-button and handle thereof and when for example we
employ a padlock through such loops or holes in the cam-button the scrows in the
lugs become thereby protected or we may employ other suitable locking devices
whereby such screws are secured against tampering when protected by the yoko.
When using this as a simple fastener the yoke may if desired be dispensed with
and a slotted plate secured upon one of the members to be fastened, be slipped over
the cam-button which then fastens itself as above explained.
When it is desired to prevent any absolute locking of a door altogether but only
to provide against the door being opened further than the bracket-plate will slide
in the slotted plate or yoke we may dispense with the cam-button and employ other
suitable means when required. We may employ a spring or other suitable retaining
devices to hold the yoke in the required position but which will not prevent the
door from being opened as far as the bracket-plate will slide in the yoke and we
may employ such spring or other dorices in combination with or actuating a bell or
other signal or alarm.
To prevent rattling of the door when fastened we may provide inclined surfaces
upon the yoke where the cam-button bears upon it preferably with stops to prevent
the button from turning too far.
To fix the door partly open at different positions we form recesses in the yoke to
engage with the bracket plate or recesses therein or with one or more corresponding
projections thereon and we may preferably provido recosses in the yoke of such
varying angles that they will respectively fit tight upon the bracket-plate or
recesses therein or projections thereon according to the extent of the opening of
the door, and one or more stops may be provided upon the bracket-plato and
recesses in the cam button and handle thereof to stop the cam button in its
extreme positions, or the pivot of the button may be so arranged as to accomplish
this.

Improvements in Bolts or Fasteners for Doors, Windows, and
the like.
We, HORATIO SAQUI of 29 and 30 Liverpool Street, in the City of London,
Jeweller, ERNST JAUNOKE, of Canonbury Works, Dorset Street, Essex Rond, in
the County of Middlesex Metallic Box Manufacturor, and THE "FUTURE" BOLT
SYNDICATE LIMITED of 17 and 18 Telegraph Street, Moorgate Street, in the
City of London, 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 a fastener for doors of various kinds such as house
doors, railway-carriage doors, cabin-doors, and the like, and also window sashes
and the like, and is so designed that it may be used as a bolt for entirely fastening
the door close or may be employed for the same purpose as tho well-known door
chain which allows the door to be opened to a certain extent but no further.
In carrying the invention as applied to doors into effect we prefer to employ a
slotted yoke the pivotted end of which is by preference adapted to act as a spring
catch upon the well-known principle of the pocket articles such as cork-screws, the
effect being that the spring has a tendency to koop the yoke in a certain angular
position, but that the yoke can nevertheless be moved into other positions as
required. Any other suitable form of spring or spring catch may however if pre-
ferred be employed for this purpose. The bracket to which the yoke is pivotted
may be secured upon the door or window frame or the like; this bracket is pre-
ferably in two portions one fixed and the other pivotted so as to allow the slotted
yoke to be turned preferably a limited distance only. Upon the door or sash is
secured a suitable bracket catch or equivalent which may consist of a flat plate
having a headed projection extending towards the pivot of the yoke. Upon the
plate is pivotted a cam-button having a projection or handle by which it may be
turned preferably to the extent only of about a quarter of a revolution. The
action of this apparatus is as follows:-
The door being closed, but not locked, the slotted yoko is turned upon its pivot
and pressed upon the cam-button so as to turn it upon its centro and raise the
projection or handle into a line with the slot of the yoko in consequence of which
the yoke can be passed over the button which then being overbalanced turns upon
its centre and locks the yoke in position. To release the door the cam-button must
be turned by the operator upon its centre and held while the yoke is removed when
the door can be opened.
If however it be desired, while releasing the cam-button and absolute bolt, not
to allow the door to be entirely opened the slotted yoko is opened to the point at
which its spring causes it to rest. It then lics inside of or against the head of the
bracket plate of the door. The slot of the yoke itself is enlarged at the pivot ond
to allow of that portion of the yoke passing freely over the head of the bracket
plate. The door being closed and the yoke in the described position if the door ba
opened the door itself will press against the yoke and turn it further upon its pivot
as the door opens, but the door will only be able to open so far as the bracket-plate
cun slide in the yoke, the slot of which prevents the head from slipping off the
plate. The operation of this part is similar to that of the well-known door chain.
To
open the door ontirely the yoke must while the door is closed, be turned so far
open as to prevent the head of the bracket-plate locking itself in the yoke in the
manner previously described. The spring of the yoko prevents it from swinging
backwards and forwards and excepting for its one normal point it remains where it
is placed.
As it is sometimes desired to place this apparatus upon the outside of a door,
say a street door, it is desirable to be so able to fasten or lock it that it cannot be
tampered with, and also to so arrange it that the, screws by which the parts are
held to the door or framework cannot be removed until the apparatus is opened!

page_text: For this purpose we provide means of locking the parts which may be effected in
various ways. For example a hole may be made through the cam-button in any
required part and through this hole a padlock may be placed so that even if the
cam be turned the yoke cannot be lifted and the fastening is thus maintained. Or
one or more loops may be provided in any required manner and at any required
part or parts upon the bracket-plate and the pad-lock placed through as before. Or,
again, a lock may be placed within the button or locking plate in such a manner
as to secure the parts; when the look is placed in the cam it may be arranged to
operate by preventing the cam from being turned at all.
By securing the bracket-plate by screws passing through lungs extending there-
from the lock may be arranged to cover these screws so that they cannot be got at
until the yoke is lifted which cannot be done when the apparatus is locked.
Similarly the screws holding the yoke bracket upou the frame may be arranged
so as to be covered by the yoke or other portion of the apparatus. The screws
however may be otherwise placed or arranged so long as they are protected when
the apparatus is closed.
To secure the scrows on the bracket-plate from boing withdrawn when the yoke
is lifted we provide means whereby they are protected and we may preferably
employ lugs in such position on the bracket-plate with relation to loops thereon or
to a hole or holes in the cam-button and handle thereof and when for example we
employ a padlock through such loops or holes in the cam-button the screws in the
lugs become thereby protected or we may employ other suitable locking devices
whereby such screws are secured against tampering when protected by the yoke.
When using this as a simple fastener the yoke inay if desired be dispensed with
and a slotted plate secured upon one of the members to be fastened, be slipped over
the cam-button which then fastens itself as above explained.
When it is desired to prevent any absolute locking of a door altogether but only
to provide against the door being opened further than the bracket-plate will slide
in the slotted plate or yoke we may dispense with the cam-button and employ other
suitable means when required. We may employ a spring or other suitable retaining
devices to hold the yoke in the required position but which will not prevent the
door from being opened as far as the bracket-plate will slide in the yoke and we
may employ such spring or other devices in combination with or actuating a bell or
other signal or alarm.
To prevent rattling of the door when fastened we may provide inclined surfaces
upon the yoke where the cam-button bears upon it preferably with stops to prevent
the button from turning too far.
To fix the door partly open at different positions we form recesses in the yoke to
engage with the bracket plate or recesses therein or with one or more corresponding
projections theroon and we may preferably provide recesses in the yoke of such
varying angles that they will respectively fit tight upon the bracket-plate or
recesses therein or projections thereon according to the extent of the opening of
the door, and one or more stops may be provided upon the bracket plate and
recesses in the cam-button and handle thereof to stop the cam-button in its extreme
positions, or the pivot of the button may be so arranged as to accomplish this.
In the accompanying drawings
Figure 1 is a face view of the complete apparatus.
Figure 2 is a side view of the same partly in section.
Figure 3 is a view of a portion of a door with the apparatus attached.
Figure 4 is a view showing the yoke turned so as to hang down vertically out
of the way when not required for use.
"
Figure 5 shows the cam button.
Like letters represent like parts throughout the drawings.
A is a slotted plate or yoke pivotted at one end by the pin A¹upon the bracket B

page_text: through a hole in B in the hollow under-side of which it carries the plate B₁
which may be secured to B by rivetting, screwing, or otherwise so as to turn with
the pin B. The projecting points B' of the plate B' alternately engage with the
pin.B secured in the under-side of the plate B and projecting into the hollow
paco. This arrangement allows the yoke A to be turned in one direction into
the position shown in Figure 1 and in the other direction at right angles thereto
into the position shown in Figure 4 in which latter position the yoke A is entirely
clear of the door and the apparatus is not in use. In order to retain the yoke in
either of these positions while allowing it the necessary play in that plane only a
flat lug or projection A' is provided upon one of the jaws A at the open end of A
which engages with either of the slots B' or B formed in the face of the
bracket B. In Figure 1 the lug A³ is engaged in the slot B' and in Figure 4 it
is engaged in the slot B. The yoke A is thus carried entirely upon the door
frame. The pivotted portion B' is provided upon one face with a projection B'
and the appropriate jaw A³ with a corresponding recess A and the ends of the
yoke A being sprung apart it will be seen that it has a tendency to lie at the
particular angle in the horizontal plane due to the respective positions of
the lug and the recess. The object of this is to ensure the yoke always being in
the proper position when the door is first opened to ensure the plate which the
door carries properly entering the slot in the yoke.
Upon the door D is fixed a plate E screwed or otherwise secured to the door;
in the drawings the plate E is shown with lugs E through which pass the
screws E by which it is fixed to the door. The plate E has a T-head E' which
when the door is opened and the end of the plate E is in engagement with the
slot of the yoke A the T-head Eprojects upon each side of A and prevents A
and E from being separated. To enable the two parts to be disengaged when
the door is closed recesses A are formed in each arm of the yoke near its open
end so that they can pues over the T head E' and tlius clear the yoke A from the
plate E.
To fix the door open at certain points n stop E' is provided at the end of the
plate E and recosses A' in the yoke A so that at these points the recess A*
may slip over the lug and thus hold the two plates in engagement at those
particular points.
The plate E carries the cam button F which is pivotted at Fl so as to turn
freely. In the under-side of the cam button is a recess Fadapted to fit over a
stud or projection E' upon, the plate E so that the cam button can only turn in
que direction so far as to lie parallel with the plate E. The cam button is so
shaped at or towards the apex F that supposing it to be hanging down vertically
in the position of Figure 1 by pressing the yoke upon it it will be turned into
its horizontal position and then when the yoke is passed over it it will fall back
again into a position approximately such as shown in dotted lines in Figure 1,
this movement being automatic by reason of the button being over-balanced the
tail F being heavier than the other end. Upon the yoke A are two stops G
against one or both of which the cam button bears when turned into the vortical
position shown in Figure 1; the faces G of the yoke A which lead up to tho
stops G being inclined so that when the cam button is pressed home against the
stop Git firmly holds A and E together, and can only be itself turned out of that
position by the exercise of considerable pressure.
We have described the bracket B as being fixed upon the door frame and the
plate E as being fixed to the door but these positions may be reversed if desired.
The operation of this apparatus is as follows:-Suppose the parts to be in the
position indicated in Figures 1 and 2 the door would be secured as by a bolt and
could only be opened by the turning of the cam button Finto the horizontal
position, and the lifting of the yoke over or past the cam button. This being
effected if the yoke A is allowed to rest where it naturally would under the
influence of the spring regulator A and B' and the door were opened it could
only go as far as shown in Figure 3 because the plate E would enter the slot in

page_text: the yoke and the head E' engaging the yoke upon each side of the slot would
prevent the two parts from becoming detached and when the position shown
in Figure 3 was reached the door could not be opened further and the apparatus
would act in a manner similar to that of the ordinary chain. If when the cam
button has been turned the plate A be turned back as far as it will go or at all
events sufficiently far to entirely clear the plate E and its head E' tho door can be
freely opened as the two parts A and E would be entirely separate; when this is
required the yoke may be turned round and allowed to hang down as shown
in Figure 4, the lug A³ then engaging with the slot B' of the plate B and thus
preventing the yoke from catching upon the door.
As a further security when the apparatus is to be locked the plate E may be
provided at one or both ends with loops HH' adapted to pass through the slot in
the yoke A and by placing a padlock through one of these loops the door can be
securely locked. If it be desired to lock the door in its open position of Figure &
a padlook may be placed through the loop H' behind the yoke A and the door
then cannot bo closed as the padlock will prevent the yoke from moving over
the plato E.
Having now particularly described and ascertained the nature of the said inven
vion and in what manner the same is to be performed, we wish it to be understood
that we are aware of the British Patent Specification of Danischewsky No. 20711:
of 1889, and do not claim what is therein published, but what we claim is :—
