A communication from abroad by JOHN CHARLES POLLERI, of Genoa, Italy.
I, WILLIAM PHILLIPS THOMPSON, F.C.S. M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn in the County of Middlesex, Civil
Engineer, 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 invention relates to locks, fasteners and the like, which are worked by simply
pushing or pulling a shaft or rod and without the use of keys, for the purpose of
opening. The movement of the shaft is communicated to the bolt or locking bar by
an inclined surface or wedge, the direction of the motion of the shaft being at an
angle with the bolt (preferably a right angle). By this device, the movement of the
bolt, as hereafter explained, can be made perpendicular with the surface of the post or
frame on which the lock is applied. The door, window, etc., can thus be opened by a
back or forward movement of the shaft.
The inclined surface or wedge may be applied, either upon the shaft, which crosses
the bolt inside the lock, and through the frame, or upon the bolt, just as desired.
In the accompanying drawing Fig. 1. shows a shaft A, B, provided with a wedge
which is capable of movement at an angle with the locking bar or bolt D, E. The
part C of the wedge meets an obstacle of any desired shape, such, for instance as the
peg o, with or without buckle, so as to receive the movement from the wedge and
transmit it to the bolt or locking bar D, E..
Fig. 2 on the other hand, represents the device with the wedge applied on the
bolt D E, in which case, the peg must be on the shaft A B, so as to communicate
the movement to the wedge, and consequently to the bolt. The bolt commences to
move when the peg o touches the wedge at or about the point o.
In both cases, the movement is effected by pushing or pulling one of the extremities
of the shaft by the hand, for example, in the locks represented in the accompanying
drawing, the movement is effected by pushing the end B, towards A, or by pulling
the end A.
It is obvious that the movement of the shaft and of the bolt, can only be in the
direction of their respective lengths, which movement, when the shaft is longer than

page_text: the case or box as shown in the drawing, is regulated by holes on each side of the
case, otherwise it is necessary to use suitable guides.
The bolt and shaft, may be made to return to their first position, either by means
of a spring of any desired shape or form, or by means of a second wedge, working in
opposite direction to the first, as shewn in figure 3. The bolt can therefore be made
to engage the shaft in either direction, viz. in one direction by the action of the right
band wedge upon the peg o, when B is pushed towards A; and in the other direction
by pushing A towards B, whereby the crank returns to the position shown in Fig. 3,
by means of the action of the left hand wedge upon the peg
The above mentioned device, may be applied, either directly upon the bolt, or upon
the shaft, as described, or upon any other part inside of a separate case as is shewn, for
example, in Fig. 4 in which the piece 1) E, instead of being the locking bolt, is simply
a small metal bar which receives movement from the shaft A B, by means of a wedge
and communicates it by means of its extremity D, which has been purposely made
with a small hole or a hook so as to be placed in communication with the locking bolt,
either by a chain, wire, or any other suitable substitute and in this way the devico
may be applied at any reasonable distance from the frame of the window door,
draw, etcetera by simply lengthining or shortening the chain or wire.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
1. The improved lock or fastener worked without the use of keys in which a shaft
or rod, which is moved back or forward by hand, actuates by means of the com-
bination of one or more wedges with suitable pegs, the locking bolt and causes it to
move perpendicularly to the said rod, substantially as described.
2. In a keyless lock or fastener, the combination of a bar having a wedge, and a
locking bolt having a peg with or without a buckle, substantially as described in
reference to Figure 1 of the drawing.
3. In a keyless lock or fastener, the combination of a locking bolt, having a wedge,
and a shaft having a peg, with or without a buckle substantially as described in
reference to Figure 2 of the drawing.
4. In a keyless lock or fastener with sloping hasp, the combination of a shaft and
locking bolt working perpendicularly to each other by means of the combination of a
wedge and a peg and a spring of any description, whereby the locking bolt is caused
to return automatically to its normal position as soon as the back or forward action of
the shaft has ceased, substantially as described.
5. In a keyless lock, or fastener with flat bolt or hasp, a shaft and locking bolt,
which work perpendicularly to each other, by the combination of two wedges and two
pegs working in opposite directions, which either open or close the lock by pushing or.
pulling the shaft and vice versa, substantially as described in reference to Figure 3 of
the drawing.
6. The combination with a lock or fastener of the device, substantially as set forth
on Figure 4, which may be placed at any distance from the lock, and provided with a
wire, chain, or other suitable device attached by means of a hole, hook, or other
suitable appliance, whereby the pushing and pulling movement of the shaft A B
causes the lock to be opened or closed at any reasonable distance from the said
shaft.
