page_text: We, THE HONOURABLE ROBERT WILLIAM HENRY RODNEY, Thornbury Park,
Gloucestershire, Gentleman, and WILLIAM MABERLY LLEWELLIN, 15, King Square,
Bristol, Glos., Consulting Engineer, do hereby declare the nature of this inven
tion to be as follows:-
Our invention has for its object further improvements in locking bolts for
which the said Honourable Robert William Henry Rodney applied for Pro-
visional Protections the same being dated respectively August 24th 1898
No. 18181.
One modification of this invention is in the application to what will herein-
after be termed "push & rill" bolts in which by a simple push or pulling action
the bolt can be pulled out of or pushed into its position for fastening or un-
fastening a door. We carry this part of the invention into practice in manner
as follows: —
The bolt is made to slide within a metallic casing of circular or other suitable
section, this casing will be hereinafter termed the case.
The bolt has fixed on it one or more pins which fit into elongated slots cut
in the case and the throw of the pins in the slots regulates the "throw" or
amount of "travel" of the bolt.
In order to prevent the case revolving upon its longitudinal axis I fix a piece of
metal to the lock or lock plate and insert one end which is suitably shaped into
a slot or hole in the circular case, or fix on the end of the tube which is in-
serted in the door a wedge or other suitably shaped piece which penetrates the
wood at the end of the recess and fixes the tubular casing, or a suitable pro-
jection may be put on any suitable outside portion of the tubular case, which
projection will engage in the material of which the door is formed either by
having a recess formed in the material or allowing the projection to pass into
the material as my be required.
A modification of this arrangement when it is desired to operate the bolt so
as to slide the bolt in or out of an engaging piece as may be required is arranged
as follows: To the pin or pins is attached a handle or handles to one or more of
the pins. A small bolt or sliding or pivoted-piece is fixed more or less at right
angles to the locking bolt and this catch bolt engages in a slot or hole in the
locking bolt and thus fastens the locking bolt so that it cannot be moved either
to or fro until the catch bolt is withdrawn.
A further improvement is in reversing the action of the bolt so as to convert
it from a right.handed bolt into a left handed bolt, or a left handed bolt into a
right handed one is carried out in manner as follows:-
That part of the bolt in which the cam is situated will be called the " cam
piece" and that part which comes in contact with the striking plate fixed to the
jamb of the door, will be hereinafter called the "striking piece these parts
are made separately but are connected together in manner as hereinafter described.

"
One end of the cam piece has either a chase" or a "feather" formed in it
and one end of the striking piece has also either a chase or a feather formed in
it so that the feather of the cam piece can fit into the chase of the striking
piece or alternately the chase of the cam-piece may fit on the feather of the
striking piece as may be desired. In order to securely connect these two pieces
together a screw is inserted more or less in the axis of the bolt from the striking
piece and screwed into the cam-piece, it will thus be seen that without with-
drawing the bolt from its casing the screw can be unscrewed from the cam-
piece and withdrawn from the striking face of the striking piece the striking.piece
can then be withdrawn and reversed as required.
Another way of effecting the changing of the bolt into right or left hand as
may be required is effected as follows:-One or more dove-tailed chase or chases
is or are formed on either the end of the cam piece or the end of the striking
piece of the bolt, and one or more corresponding, projecting piece or pieces
or feather or feathers is or are formed on the end of the striking piece, these
pieces may also be tapered so as when they engage as they are driven home they
tighten themselves.
A further improvement consists in placing a coiled or other suitably shaped
spring at the back or any other suitable position in the bolt so as to keep the
striking part projected in order to engage with the striking plate.
In order to secure greater simplicity & cheapness of manufacture we can if
needful do away with the cam being made separately and fixed to the cam piece.
to effect this I cut the cam out of the solid metal of the cam piece and I also.
make the recess into which the bolt of the lock fits in by means of a groove or
chase in the bolt partly through the thickness of the cam-piece. In order to
prevent the bolt being pushed back too far a stop is put in the back or some other
suitable part of the bolt and working in a slot in the tube or against the tube end..

We, THE HONOURABLE ROBERT WILLIAM HENRY RODNEY, The Parks, Thorn.
bury, Gloucestershire, Gentleman, and WILLIAM MABERLY LLEWELLIN, of 15,
King Square, Bristol, Civil Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
Our invention relates to improvements in that class of apparatus videlicet―
locking bolts and improvements in same for which Letters Patent have been
granted to the Honourable Robert William Henry Rodney entitled improve-
ments in catches & locks for doors and dated August 24 1898 number 18181.
In order that our invention may be more clearly understood we annex hereto
two sheets of drawings which are to be taken and read as part of these presents.
Figure 1 is a transverse longitudinal elevation of what will be hereinafter called
the push and pull pattern bolt. This drawing is partly in section.
Figure 2 is an elevation of the end of the bolt.
Figure 3 is a longitudinal elevation of the push and pull pattern bolt.
Figure 4 is a transverse section showing one way this pattern bolt is fastened.
Figure 5 shows an arrangement of making the striking part of the bolt
reversable.

page_text: Figure 6 shows the method of attaching a lock to the push and pull bolt.
One modification of our invention is for use in swing doors, i.e., doors that
swing open both ways.
•
Figure 7 is a plan of a method of joining the cam end and the striking end of
the bolt.
Figure 8 is a sectional elevation upon the line X¹ Y2 of Figure 7.
Figure 9 is an elevation of the bolt showing the arrangement of the cam.
In Figure 1A is the metallic casing C a slot in the casing which regulates the
throw or amount of traverse of the bolt by means of the pin B which comes in
contact with the casing at the ends of the slot C.
F is the rounded end of the bolt which engages with a suitable striking plate
fixed in the jamb of the door. D is a spring that keeps the rounded part pro-
jected beyond the casing.
A is the closed end of the bolt tube or casing A, against this closed end of
the tube one end of the spring abutts against whilst the other end of the spring
pushes against the end of the bolt H.
Fixed to the closed end A¹ is a projecting piece E which is forced into the
wood or other material composing the material of the door and thus prevents
the casing A from revolving in the door in which it is fixed. Another improve-
ment is shown in Figure 3.
When it is desired to fix the bolt in a 66
shot" position that is to say with the
part projecting beyond the tube A, there is fixed near the bolt casing a small
bolt of any of the well known forms such a bolt is represented in Figure 3 of
which I is the plate of the bolt. J are holes in the plate for attaching bolt to
the door. W is the bolt. X is the handle of the bolt. K is the part of the
bolt W which fits in the suitably shaped slot or hole K' of the bolt H. By (By)
having the holes K¹ placed in certain other positions as required it is obvious
that the bolt H can be locked in certain other positions as desired. Figure 4 is
a transverse section of the bolt. G is the handle for moving the bolt H from
its "shot" position when and as required. Figure 5 shows a method of reversing
the striking part of the bolt II, the parts H & H of the bolt are made separately
upon the part H₁ is formed a sturt of any suitable shape N this fits into a suit-
ably formed recess N₁ the parts H and H are connected together by the threaded
screw M which passes through a hole in the bolt part H' and engages its
threaded end in the suitably threaded hole O, the head of the screw fits in a re-
cessed space U, it is obvious that an alternative arrangement is by having the
socket part made in H' and the sturt part made in the bolt part H, the position of
the screw will remain the same in either arrangement.
Figure 6 shows the arrangement by means of which when a lock is attached to
the bolt the chase into which the bolt of the lock fits is cut out of part H of the
bolt P is the bolt of the lock Q & P₁ the slot or chase milled out of the bolt H.
Qis the lock S is a plate attached to the tubular casing A. R are
passing through the plate and screwed into threaded holes in the lock thus
securing the lock to the plate.
screws
Figures 7 and 8 show another arrangement for converting a right handed
bolt into a left handed bolt H¹ has formed on it a dovetailed piece Y and H has
a corresponding chase Y¹ cut out into which the part Y fits.
Figure 9 is an elevation of the cam part of the bolt showing another method
of forming the cam. The cam is formed out of the solid metal of the bolt and
consequently there are no loose parts in connection with the cam on reference to
the drawing it will be seen that the cam F is formed by having a suitably
shaped space on each side of it cut away these spaces are M¹ M" and into
these two said spaces pass the wings N' N" of the spindle G¹ the function
of this spindle has been described in Specification No. 18181 of 1898.
Z is a sturt which by striking against the end A¹ of the tube A prevents the
bolt from being thrown too far back, this modification of spring can be used
instead of that shown in Figs. 1 & 6.
