PROVISIONAL SPECIFICATION.
An Improvement in Bolts for Safes, Strong Rooms, Deed Boxes,
Doors, and other Artioles.
THOMAS WILLIAM WILSON 327 Dudley Road Birmingham Warwickshire,
Iron Safe Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a bolt which shall automatically wedge itself in position
when thrown out of the bolt-chamber.
The bolt consists of two parts lying side by side, which are hinged together at
one end leaving the other ends free to expand or close.
These free ends are shot out of the bolt-chamber and as they move forward they
are caused to expand into a vee-shape, by a pin, or division of bolt-chamber. The
cup into which the bolt-ends shoot are formed in a corresponding vee-shape.
By action of the handle, or such means as are used to shoot the bolt, a tongue of
metal is introduced between the two parts of the bolt, which entirely prevents these
said parts from closing. Thus the bolt is locked in position untill the handle, or
proper means, is used to withdraw it.

COMPLETE SPECIFICATION.
An Improvement in Bolts for Safes, Strong Rooms, Deed Boxes,
Doors, and other Articles.
THOMAS WILLIAM WILSON No. 2 Cambridge Cottages Capo Street Dudley
Road Birmingham formerly of 327 Dudley Road Birmingham, Safe Maker,
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 bolt which shall automatically wedge itself in position
when thrown out of the bolt chamber.
This bolt consists of two parts lying side by side, which are hinged together at
one end having the other ends free to expand or close. These free ends are shot
out of the bolt chamber, and as they move forward they are caused to expand into
a vee-shape, by a wedge in the bolt chamber.
The cup into which the bolt is shot is formed in a corresponding vee-shape.
By action of the handle or such means as are used to shoot the bolts, a tongue of
metal, wedge shape, is introduced between the two parts of the bolts which entirely
prevents the said parts from closing.
In order to more clearly explain this my said invention, 1. append hereunto an
illustrative drawing upon which are figures and numbers of reference similar
numbers throughout the several views referring to the same thing or part, and in
which,
Fig. 1, is a view of the locking mechanism, more particularly showing the bolts
as they appear when shot into their respective cups.
Fig. 2. is a detailed view of one half of bolt.

page_text: Fig. 5, is a view of the locking mechanism, showing the bolts when in their
withdrawn position.
6, 6, are the bolt reins; 7, 7", are the bolt bars; 8, 8, are the wedge reins;
9, 9', are the wedge bars; 10, 10* &c., are the bolta; 11, 11ª, are the bolt hole
plates or lock case faces.
The bolts 10, are made in two parts (one half of which is seen in detail in Fig. 2),
which are jointed together at 12, and carried upon the holt bara 7, 7", by the
pins 13. These bolts have a shooting forward and receding motion imparted to
them as follows:-By means of an exterior handle (not seen) the throw 14, is
moved a given distance about a centre 15. This throw is connected to the bolt
reins 6, 6, by the joint pins 16, 16; hence, as the throw 14 is moved in the one or
other direction, the bolt bars 7, 76, and with them the bolts 10, are shot outwards
or drawn inwards. To these bolt bars are secured the wedge reins 8, 8"; which
run in guides 17, 17; and which are further secured at their other ends to the
wedge bars 9, 9. Thus with the in and out motion of the bolt bars 7, 7", a similar,
but opposite, in and out motion is imparted to the wedge bars 9, 9, that is, whon
the bolt bar 7, for instance, is thrust outwards, the wedge bar 9, is drawn inwards,
by reason of its being secured to the bolt bar 7, upon the opposite side, which
moves simultanconsly in the opposito direction. Upon the wedge bars 9, 9, are
secured the wedges 18 (see Fig. 4), which lie between the two (half) bolts. Hence
when the said bolts are thrust outwards, as seen in Fig. 1, the wedges 18, are
drawn inwards between their two parts, and thus expands them as they shoot
forward. When thus shot forward the bolts enter the cups or chambers 19, 19º,
see Fig. 3, which said cups are shaped to correspond with the ends of the bolts.
As the bolts are withdrawn (or unlocked); the wedges are simultaneously pushed
outwards and thus they (bolts) are permitted to close together as they are drawn in
as shown in Fig. 5.
20, is the ordinary lock by which the bolt reins are locked.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The combination with locking mechanism for safes, strong rooms, deed boxes,
doors and other like articles, of a bolt having a wedge like entrance into the cup or
other bolt hole substantially as set forth and shown upon the drawings.
2. The combination in locking mechanism for the purposes herein named with the
divided or two part bolt, of the wedge 18, as described and shown.
8. The combination with the wedge like acting bolt, and the wedge, of the
wedge shaped cup or bolt hole as described and shown.
