page_text: I, WILLIAM FRASER of 6 Livery Street Birmingham in the County of Warwick,
Engineer do hereby declare the nature of this invention to be as follows:-
The object of this Invention is, that a door may be closed & locked without the
slightest noise being caused in any-way whatever.
To obtain this result a small wheel with wing's upon it is placed or secured to the
box staple & striking plate of the door, if for rin locks, & to this Door striking plates
if for Mortace Locks. The wheel acts on the same principle as a turn-stile & will only
rovolve one way.
The winged wheel (for ordinary Locks) requires to be about 1" in Diar. & about 1"
long the wings of the wheel stands upright having an axle at each end about diar.,
and is supported by a bracket at top & bottom, the latter bracket or plato having
notches about "in depth on the upper side. The distance between the two brackets
if the turnstile stands say 1" high would be 14". This allows the turnstile of the
striking plate sufficient space to rise & fall every time the door is closed. The
Door is opened by turning the handle of the Lock, in the ordinary way. Then to
close the Door either by the hand or with a Door closer, the bolt of the Lock does not
require to be pushed in or back, the moment it comes in contact with the turnstilo or
rather one of the wings of it, it causes same to revolve or partly turn round & con-
tinues to turn round same untill the door is properly closed or hard up against the
stop then the turnstile or winged wheel of the door plate drops into the notches on
the upper side of the bottom plate or bracket by the weight of itself, but if considered
necessary a small spring can be used to assist the down action of the turnstile, (either
above or below).
The bolt of the Lock must be drawn back to open the Door as the turnstile can only
be revolved one way.
The lock-bolt being held in the same way by the turnstile as with an ordinary box
staple or striking plate & will only revolve by the closing of the Door.
Thus a Door can be closed without the slightest noise being caused.

page_text: The Lock will last as long again in consequence of one half of its work being
dispenced or done away with.
No force or pressure is required to close a Door as the Turnstile is only about 1 oz.
weight or thereby & has only to revolve about turn every time the Door is opened
& closed. It therefore offers no resistance whatever to the closing of the Door com-
-pared with the ordinary bolt with a spring behind it, which in the first place requires
considerable force to put the bolt in or back.
Secondly the moment it is relieved the bolt is sent back with such a force as to cause
considerable noise & irritation to every body within hearing.

Improvements in or in Connection with Fastenings of Doors.
I, WILLIAM FRASER, Engineer 6 Livery Street Birmingham 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 this Invention is to enable a door, window, or any other hinged or
pivoted appliance made for opening or closing, to be opened, closed, or locked without
the slightest noise being caused in any way whatever.
According to my Invention the part of the striking plate immediately opposite the
bolt of a lock is cut away sufficiently to allow the bolt free access; that is, the striking
plate does not push or cause the bolt of a lock to be sent back when closing.
In the cut away part opposite the bolt supported by a top and bottom bracket (or
any other suitable appliance) is a winged cylinder or turnstile with four, or more or
less leaves as desired, which revolves upon a top and bottom axle upon said bracket.
The uppermost side of the bottom bracket being fitted with slots, holės or raised
parts, that the cylinder when turned by the closing process of the door, drops into
same, thus preventing the door from opening until the bolt is reversed in the ordinary
way, i.e. the winged cylinder or turnstile will only revolve one way, the way the door
closes. To open a door with said appliance attached, the handle of the door is turned
in the ordinary way, the bolt being drawn back, the winged cylinder or turnstile
remaining fast in the bottom bracket. The moment the door closes and the bolt comes
in contact with same, or with one of its wings, it causes same to revolve or partly turn
round, and continues to do so until the door is completely closed or hard against the

page_text: stop; it then drops into the notches, holes, or raised part on the upper side of the
bottom bracket by its own weight, and thus secures the door.
A small spring can be applied to assist the movement of the winged cylinder. The
two brackets and winged cylinder can be adjusted to suit any lock, as they can be
drawn backward or forward by means of two screwed pins that supports the top and
bottom brackets respectively i.e. the winged cylinder can be brought nearer the bolt,
or put further back as required.
It can therefore be adjusted to suit any kind of bolt or lock.
It is also provided with an adjustable buffer which can be drawn backwards or
forwards to catch the bevelled side of the bolt when the door is closed, thus preventing
the door coming in violent contact with the stops, thereby making a noise.
The heads of the pins both for the brackets of the winged cylinder and the buffer
are notched and flush with the outside of the plate, the other ends of the pins, being
supported by an inside bracket.
I will now
proceed to describe with reference to the accompanying drawings the
manner in which the same is to be performed.
Figure 1 of the accompanying drawings shews an elevation of my Invention in
connection with a lock, shewing the latch bolt of same, revolving the turnstile or
winged cylinder marked a.
Figure 2. is a horizontal section on the dotted line A. B. Figure 1 A. is the winged
cylinder. D² is an adjustable pin, for the bottom bracket. E. is an adjustable pin for the
buffer or cushion. E is the cushion on same. Es being the carrier for same.

respectavely is the catch pins.
Figure 6. is an underside plan of figure 5.
Figure 7. marked D³ is a section of the bottom bracket or cylinder seat shewing
the piercings for the catch pins marked F¹ & F' respectively. D & D being the
two thro' holes for the adjustable pins the latter being screwed to fit same.
Figure 8. marked D³ is a plan of Figure 7. shewing the holes for engaging with the
pins A¹ and A' as shown in figure 5 D¹ being the hole for A' (in Figure 4)
working in.
Figure 9. shews a horizontal section of buffer & carrier marked E & E³
respectively.
Figure 10 is an edge view of figure 9. the hole inarked E' being scrued to engage
with the adjustable pin E in Figures 2 & 3.
Figures 11. 12. 13. & 14. shew a different method of holding or preventing the winged
cylinder from rotating (but only the one way) the seat of the cylinder bracket as shewn
in figure 11. is notched & the bottom of the cylinder end as shewn in figure 13. has
corresponding notches, then by the closing action of a door the cylinder is caused partly
to revolve same rising & falling alternately in the notches as the door is opened &
closed, & is the same as the others in action as shewn in Figures 1. 2. 3. & 4. & will
only revolve one way.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is.
First a lock or latch plate consisting of an enclosing plate or casing as shewn in
figure 1. for the purpose described & set forth.
Secondly, in having a revolving winged cylinder as shewn in figures 1. 2. 3. 4. 5. 6.

at top & bottom as particularly shewn in Figure 4. & marked A³ & A* respectively,
for the purpose described & set forth.
Thirdly in having two or any number of adjustable brackets as shewn in figure 4.
in particular & marked D' & D³ with holes or slots as shewn in figure 2. & marked
FI2..3. & 4 respectively, & also in Figure 7. F & F & also in Figure 8. 11. 12. 13.
& 14 for the purpose described & set forth.
Fourthly in having two or any number of adjustable or permanent pins as shewn in
figure 4. & marked D. & D for the purpose described & set forth.
Fifthly in baving an adjustable or permanent buffer in combination with my revolving
latch staple for engaging with a bolt or lock of a Door & preventing same from coming
into violent contact with the door stop as shown in Figure 4. & marked E2 with back
brackets marked D & D respectively & as shown also in Figures 9. & 10 for the
purpose described and set forth.
Sixth & lastly a combination lock. or latch staple with gapped side plates with a
revolving curved or plain winged cylinder to be partly or wholly revolved by the
action of a door or its equivalent & to rise & fall either by a spring or its own weight
& drop into holes or slots or other suitable apparatus for securing saine & preventing
it from revolving but one way with suitable & adjustable pins & brackets for adjusting
a winged cylinder, to suit any length of lock or bolt with an adjustable buffer or
cushion with back or front brackets (or both) with adjustable pins sunk flush, with
the outside plates of a latch staple notched or otherwise to enable adjustment being
made without disturbing or having to take off latch staple substantially as set forth &
described & illustrated in said drawings.
