PROVISIONAL SPECIFICATION.
Improvements in Fastenings for Doors, Gates, and the like.
We, HENRY CLAY WEBB, of 9 Rozel Terrace, Church Road, Lamp Dealer,
HENRY ROBERT HARVEY, of 7 Church Road, Engineer, and SYDNEY BALDWIN,
of 21, Borough Hill Builder's Foreman, all in Croydon, in the County of Surrey,
do hereby declare the nature of this invention to be as follows
-
Our invention has for its object to provide bolts for doors gates &c. that will
work more easily than the bolts in use, and allow for the sagging and warping of
doors gates &c. According to our invention we make one or both ends of the bolt
tapering and also the socket into which the bolt enters tapering The case through
which the bolt slides is made in two or more parts and in or near the centre of case
a spiral slot is made at au angle proportionate to the length of motion required. We
also provide a short lever which is caused through the slot and fastened in the
bolt
At one or both ends of the slot is a small recess which holds the lever from
dropping. The small end of bolt being presented to the lage end of socket
making the act of bolting or unbolting easy.

We, HENRY CLAY WEBB, of 9, Rozel Terrace, Church Road, Lamp Dealer,
HENRY ROBERT HARVEY, of Church Road, Engineer, and SYDNEY BALDWIN,
of 21, Borough Hill, Builders' Foreman, all in Croydon, in the County of Surrey,
do hereby declare the nature of this invention and in what manner the same 18 to
be performed, to be particularly described and ascertained in and by the following
statement
-
Our invention relates to bolts or fastenings for doors, gates and the like and has
for its object to provide a bolt that will work more easily than bolts at pieseut in
use, especially upon doors which have sagged on warped.
A bolt constructed according to our invention is adapted to be projected from
either end of the casing or socket in which it slides and is operated by means of a
lever or handle bxed to the centre of the bolt and moving through a spiral slot or
opening formed in the said case, in such a manner that the movement of the bolt
upon its axis through an angle of 180 degrees causes the projection of the bolt from
one end or the other of the casing. A spring is advantageously employed for
preventing the handle of the bolt from operating by gravity and a spial slot 18
formed at one end as an additional precaution
The ends of the bolt are advantageously made tapering and the sockets or
holdfasts into which the ends of the bolt are projected are also preferably tapening.

page_text: To enable ou invention to be fully understood we will describe the same by
reference to the accompanying diawings, in which :-
Figure 1 is an elevation of our improved bolt in its unfastened position; and,
Figure 2 is a sectional elevation shewing the bolt fastened:.
Figure 3 is a sectional side view of the bolt in the position shewn in Figure 2,
the section being on the line 3-3, Figure 2:
Figure 4 shews the recess at one end of the spiral slot.
a indicates the casing of the bolt, the plate to which the same is attached,
and the bolt proper both ends of which, as shewn, are made tapering d is the
bandle fixed to the bolt, and e is the spiral slot through which the said handle
passes, the pitch of the said slot, as shewn in the drawing, being such that the
.movement of the handled through an augle of 180 degrees will project the bolt
from the position shewn in Figure 1 to that shewa in Figure 2 or vice versa
will be understood that the pitch of the slot will be varied according to the extent
to which the bolt is to be projected.
It
In the bult shewn in the drawing, the weight of the handle will, when the bolt
is shot either downwards or to the left hand, prevent the accidental moving of the
same. To provide for retaining the bolt when shot upwardly or to the night hand,
the slot is formed at one end as at f, Figures 3 and 4, and a spring such as f¹ 18
fixed to the plate a of the bolt and has its free end bent, as clearly shewn in
Figure 3, so as to press and retain the handle in the recess f.
In some cases it will be found desirable to provide a recess f and spring fat
each end of the slot e.
is the hold-fast or socket which is made tapering so that when the bolt is shot
it will fit the said socket as shewn in Figures 2 and 3.
It will be obvious that this arrangement of tapering the end of the bolt and
making the socket of a tapering shape is very advantageous as, in case a door sags
or warps, the small end of the bolt, being opposite to the large end of the socket,
can still enter the said socket without striking the edge thereof as in ordinary bolts,
and, furthermore, as the bolt is fully shot the door will be pulled into its proper
position owing to the contact of the inclined sides of the bolt end and socket.
Also in unbolting a door which has sagged or warped, with this arrangement it will
be much easier than with the ordinary bolts.
Although we have described the bolt as having its ends tapering, this is not
necessary but we prefer that one or both ends should taper, and furthermore
although we prefer to employ a tapering socket, such is not absolutely necessary
as a parallel socket may be used.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim 18:
1 A bolt or fastening for doors, gates and the like wherein the bolt proper has
its handle passing through a spiral slot in the case in which the said bolt proper
slides, so that the longitudinal movement of the said bolt will be effected by rotating
it upon its axis, substantially as described.
2. A bolt or fastening for doors, gates and the like adapted to be moved
longitudinally by means of its handle working in a spiral slot and having one or
both of its ends made tapering, substantially as described.
3. In a bolt or fastening for doors, gates and the like wherein the bolt is projected
by a pin or handle moving in a spiral slot, a recess at one or each end of the said
slot in combination with a spring substantially as described.
4. The combination with a bolt or fastening for doors, gates and the like having
its end or ends made tapering and adapted to he moved by a handle working in a
spiral slot, of a tapering socket into which the bolt 18 projected substantially as, and
for the purpose, described.
5. The manufacture and use of the improved bolt or fastening for doors, gatos,

page_text: and the like constructed substantially in the manner herein before described and
illustrated in the accompanying drawing.
