page_text: ETTERS PATENT to James Kelly, of Liverpool, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN AND APPLICABLE TO
RAILWAY POINTS AND LOCKING APPARATUS FOR SAME, ALSO IN THE MEANS OF
ACTUATING SIGNALS CONNECTED THEREWITH AND INTERLOCKING SAME WITH
THE POINTS, AND COMPENSATING FOR CONTRACTION AND EXPANSION OF RODS OR
WIRES WORKING SUCH SIGNALS."
PROVISIONAL SPECIFICATION left by the said James Kelly at the
Office of the Commissioners of Patents, with his Petition, on the
10th July 1874.
I, JAMES KELLY, of Liverpool, in the County of Lancaster, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN AND
APPLICABLE TO RAILWAY POINTS AND. LOCKING APPARATUS FOR SAME, ALSO IN THE
MEANS OF ACTUATING SIGNALS CONNECTED THEREWITH AND INTERLOCKING SAME
WITH THE POINTS, AND COMPENSATING FOR CONTRACTION AND EXPANSION OF RODS OR
WIRES WORKING SUCH SIGNALS," to be as follows:-
Thi T.
Firstly. To improvements in and applicable to railway points for
j

changing the line of direction of trains from main imes to pranenes,
or from one line to another, or otherwise as is understood.
The second part of this Invention relates to locking such points when
in position and the requisite change has been effected.
Thirdly. This Invention relates to apparatus for actuating semaphore
or other signals to show line clear, or danger, as is understood.
Fourthly. This Invention relates to apparatus for automatically inter-
locking the signals with the points, so that the signals can only indicate
the position of the points, and cannot be moved without moving the
points.
Fifthly. This Invention relates to apparatus for, compensating for
expansion or contraction of wires, rods, or their equivalents for working
signals or transmitting motion caused by variation of temperatures.
The first part of this Invention consists in forming the points square,
and of the same section as the main rail. The main point and the
branch point are bolted together, and hinged or jointed to the main and
branch line at the heel chair. The length of rail, being the main point
and the branch point, move together and in unison; they are fitted in
double chairs moving on suitable guides, and having a fixed travel
thercon. They are also where required fitted on suitable half chairs, as
is understood. In front of the points, and within the guage, there are
fixed two check or guide rails to ensure certainty of the train taking the
points.
The second part of this Invention consists in fitting between these
check rails and the main rails a locking apparatus, which consists of a
bolt or bar of iron fixed on levers or their equivalents, and actuated by a
connecting rod or otherwise, and so arranged that it is capable of three
movements, namely, a rising movement, a forward movement, and a
falling movement, the purport of which will be explained hereafter, and
which I will call the point. lock. The double chairs carrying the main
and branch points at the extreme ends. are connected by a transverse rod
having in its centre a. pin fitted with an antifriction roller. The lever's
working the point locks are also connected by a transverse rod having a
pin in its centre with an antifriction roller similar to the double chairs
before mentioned. In the guage and between the rails there is fitted a
sliding plate having action parallel with the rails, and operated by
°

page_text: man.
suitable rods, levers, or their equivalents under controul of the points-
This sliding plate is fitted with two grooves or slots of peculiar
construction. Into these slots take the rollers on the studs of the
transverse bars before mentioned, namely, one slót is thereby connected
with the point lock, and the second slot is connected with the sliding
chairs carrying the main and branch points. The first slot is formed
with three distinct directions, namely, diagonal, longitudinal, and return
diagonal. The second slot is also formed with three distinct directions,
namely, longitudinal, diagonal, and longitudinal. Further down near
heel the combined main and branch points are carried on a second set
of double chairs working on suitable slides, and having a fixed travel.
These chairs are connected by a transverse bar passing over the tail of
the sliding plate, and there is a slot or groove on the under side of the
bar, which also acts as a lock by taking on to two longitudinal lugs
formed on the face of the sliding plate, and having position relative to
the side travel of the points.
The action of the gear is thus:-The first-named slot in the travelling
plate having a diagonal direction, and being in connexion with the point
lock, the second slot having a longitudinal direction, and being in con-
nexion with the points, and one of the locking lugs on the tail of the
plate taking into the groove in the transverse bar in connexion there.
with, it is evident that by the movement of the plate three motions are
obtained, namely, the point lock is lifted and withdrawn; secondly, the
locking lug on the end of the plate is withdrawn from the transverse
bar; thirdly, the combined points are free to travel and be worked.
Upon a further stroke of the plate the first slot has a. longitudinal
direction, which leaves the point lock in the position attained by the
first portion of the stroke, the second slot however having a diagonal
direction causes the combined main point and branch point to travel to
the required position by means of actuating the transverse rod before
mentioned. In the travel of the combined main point and branch
point the transverse bar passing over the tail of the plate travels also
its proportion, and brings the groove in the under side of the bar
opposite the second locking lug on the tail of the plate before men-
tioned. Upon a further stroke of the plate the first grove, having a
return diagonal direction, causes the point lock to fall and resume its
normal position, and lock securely the line, namely, for the main or for
the branch, or as the case may be. In this movement of the plate, the

page_text: second slot having a longitudinal direction the position of ou
points remains unaltered, but the second lug on the tail of the plate is
brought into gear with the groove on the tranverse bar, and in connexion
therewith acts as a further lock.
It will be seen by the before-going that the operation of unlocking,
shifting, and locking of the points is done by one movement of the
sliding plate, which is actuated by any suitable lever and rod connexion
operated by one lever and one action of the pointsman.
The third part of this Invention consists of two rocking levers having
longitudinal slots and quadrant ends. These levers are respectively
connected with and operate the signals in connexion with the points,
namely, one lever is connected with a rod operating the signal for the
main line, and the other lever is connected with a rod operating the
signal for the branch line. These levers are respectively provided with
a longitudinal slot, into which take pins or studs fixed to a travelling
bar, which is attached to and worked by the shifting of the points. The
quadrant ends of the rocking levers work across the face of a sliding
plate having a stud or projection on its centre, and so arranged that the
projection will operate which either of the rocking levers may be in gear
with it, and by this means move the signal. The signals for the main and
for the branch are by this arrangement worked by one rod, wire, or its
equivalent which operates the sliding plate, and are actuated by one
lever under the controul of the signalman.
.
The fourth part of this Invention relates to interlocking the signalling
apparatus with the locking apparatus of the points described in the
second part of this Invention, and consists in providing the rods con-
necting the rocking levers with the signals with a projection on their
under side so arranged that they can respectively be locked or free,
according to the position of a transverse bar worked by the point locking
apparatus. This transverse bar has cross grooves therein, so arranged
that the stud or projection on the signal rods will pass through or be
locked by it, according to the position of the point lock, and when the
points are unlocked both signals stand at danger, and when the main
line is open the branch signal is locked, and when the branch line is
opened the main signal is locked, so that the signalman is entirely
dependent upon the position of the points to give his signal of line
clear.

page_text: The fifth part of this Invention consists in applying to the wire or
rod for transmitting motion to the signals a toothed rack, and also a
weight which is sufficient to take up the slack, and compensate for
expansion or contraction in the rod or wire, but not sufficient to actuate
or effect the signal. Approximate to the rack there is a pawl with a
lever and weight so arranged that when the signal is not being operated
upon the pawl is out of gear with the rack, but when the signal is.
worked by the signalman the pawl is thrown into gear with the rack,
and operates the signal.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Kelly in the Great Seal Patent Office on
the 8th January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
KELLY, of Liverpool, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

after the date of the said Letters, Patent.
NOW KNOW YE, that I, the said James Kelly, do hereby declare the
nature of my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the
following statement:-
performed, to be particularly described and ascertained in and by the
following statement:-
This Invention relates,―
Firstly. To improvements in and applicable to railway points for
changing the direction of trains from one line to another.
Secondly. This Invention relates to apparatus for locking such points
when in the desired position.
Thirdly. This Invention relates to apparatus for actuating semaphore
or other signals to show "line clear" or "danger" as is understood.
Fourthly. This Invention relates to apparatus for automatically
interlocking the signals with the points, so that the signals can only
indicate the position of the points.
Fifthly. This Invention relates to apparatus for compensating
expansion or contraction of wires, rods, or their equivalents, when used
for working signals or transmitting motion caused by variations of
temperature.
The first part of this Invention consists in forming both the main and
branch points square, and of the same section as the main rail, bolting.
together the lengths of rail which form these points, and hinging or
joining them to the main and branch lines at the heel chair. Both
points move in unison and are fitted in double chairs which move with
a limited traverse on suitable guides, and where required suitable half
chairs may be used as is understood. In front of the points and within
the guage are fixed two guide rails to ensure that the train takes the
points.
The second part of this Invention relates to an apparatus which I will
call the "point lock," which consists in fitting between these guide rails
and the main rails a bolt or bar of iron so arranged that it is capable of,
a rising and falling movement, and also of a forward movement, the
object of which movements will be hercin-after explained. The double-

page_text: chairs carrying the extreme ends of the main and branch points are
connected by a transverse rod, having in its centre a pin fitted with an
antifriction roller. The levers working the "point locks" are also
connected by a transverse rod having a similar pin in its centre. In the
guage and between the rails is fitted a sliding plate which has action.
parallel with the rails, and is operated by suitable rods, levers, or their
equivalents under control of the pointsman. This sliding plate is fitted'
with two grooves or slots of peculiar construction, into which take
respectively the rollers on the two pins upon the transverse bars before-
mentioned. The first slot is thus connected with the "point lock," and
the second slot with the sliding chairs which carry the points themselves.
The first slot is formed-with three distinct directions, namely, diagonal,
longitudinal, and return diagonal. The second slot is also formed with
three distinct directions, namely, longitudinal, diagonal, and longitudinal.
The combined main and branch points are also fitted in a second set of.
double chairs placed somewhat nearer the heel of the points. These
chairs also move with a limited traverse on suitable guides, and are
connected by a transverse bar passing over the tail end of the sliding
plate before-named, and on the under side of this last-mentioned
transverse bar there is a slot or groove which in certain positions of the
sliding plate acts as a lock by taking on to one or other of two
longitudinal lugs formed on the tail portion of the face of the sliding
plate, and having position relative to the side travel of the points.
The action of the above apparatus is thus:-The first slot in the
travelling plate having a diagonal direction and being in connexion with
the point lock, the second slot in the travelling plate having a
longitudinal direction and being in connexion with the points them-
selves, and one of the locking lugs on the tail of the travelling plate.
taking into the slot or groove on the under side of the transverse bar in
connexion therewith, the result of the first movement of the travelling
plate is to lift up and withdraw the point lock, and the locking lug on.
the tail end of the travelling plate is also withdrawn from the transverse
bar, thus leaving the combined points free to travel. Upon a further
stroke of the travelling plate the first slot having a longitudinal direction
leaves the point lock in the position obtained by the first portion of the
stroke; the second slot however having a diagonal direction causes the
combined points to travel to the required position. In the traverse of
the combined points the transverse bar passing over the tail end of the

page_text: travelling plate travels also its proportionate distance, and brings the
groove or slot in the under side of this transverse bar opposite the
second locking lug on the tail end of the travelling plate. Upon a
further stroke of the travelling plate the first slot having a return
diagonal direction causes the "point lock" to resume its normal position
and so to lock the combined points. In this portion of the movement
of the travelling plate, the second slot having a longitudinal direction,
the position of the combined points remains unaltered, but the second
lug on the tail end of the travelling plate enters the groove or slot on
the transverse bar in connexion therewith, and so acts as a further lock.
It will be seen by the foregoing that the operations of unlocking,
shifting, and relocking the points is accomplished by one movement in
one direction of the travelling plate, which is itself caused to travel by
any suitable lever and rod connexion actuated by one stroke of the
pointsman's lever.
The third part of this Invention consists of two rocking levers having
longitudinal slots and quadrant ends. These levers are respectively
connected with and operate the signals in connexion with the points,
that is to say, one lever is connected with the rod and wire which move
the signal for the main line, and the other lever is connected with a rod
and wire which move the signal for the branch line. Each of these
levers is provided with a longitudinal slot, into which takes, one of two
pins or studs fixed to a travelling bar, which is attached to and moves
in unison with the combined points. The quadrant ends of the rocking
levers work across the face of a sliding plate, having a stud or projection
so arranged thereon that it will act upon whichever of the rocking
levers may be in gear with it, and by this means move the signals. The
signals for the main line and also for the branch line are both by this
arrangement worked by one rod or wire only, which operates the sliding
plate, and this sliding plate is actuated by one lever only under the
control of the signalman.
The fourth part of this Invention relates to interlocking the signalling.
apparatus with the apparatus for locking the points described in the
second part of this Invention, and it consists in providing the rods
which connect the locking levers with the signals with a projection on
their under side, so arranged that they are respectively locked or free,
according to the position of that transverse bar which is worked by the:

page_text: point locking apparatus. This transverse bar has cross grooves therein,
so arranged that the stud or projection on the signal rods will pass
through or be locked by it, according to the position of the point lock,
and when the points are unlocked both signals stand at "danger," and
when the main line is open the branch signal is both locked and
disengaged, and similarly when the branch line is opened the main line
signal is both locked, and disengaged, the signalman is therefore entirely
dependent upon the position of the points, and can only give his signal
that either main or branch line is clear when such is actually the case.
The fifth part of this Invention consists in applying to the wire or
rod, which transmits motion to the signals, a toothed rack, and also
such a weight as is sufficient to take up all slack due to expansion or
contraction of the rod or wire, but is not sufficient to actuate it or affect
the signal. In connection with the rack is a pawl with a lever and
weight, so arranged that when the signalman is not operating the
signal the pawl automatically falls out of gear with the rack, but also
automatically retakes into gear with the rack so soon as the signalman
attempts to move the signal.
The foregoing being the objects and purposes of my Invention I will
now proceed to describe more in detail how the same may be carried
into practical effect, and for that purpose I have hereunto attached two
Sheets of Drawings marked with letters and figures of reference corre-
sponding with those in the following explanation, and throughout the
various views like letters and figures denote similar parts.
Figure 1, Sheet 1, is a plan showing my Invention applied to rails
having square points and of the same section as the main rail, also
apparatus for moving and locking the points and apparatus for actuating
signals and interlocking same with the points; Figure 2, Sheet 1, is a
section through A, B, Figure 1; Figure 3, is a section through C, D,
Figure 1; Figure 4, Sheet 1, is a section through E, F, Figure 1;
Figure 5, Sheet 1, is a section through G, H, Figure 1; Figure 6, Sheet 1,
is a section through I, K, Figure 1; Figure 7, Sheet 1, is a section.
through L, M, Figure 1.
Figure 8, Sheet 2, is a plan showing my Invention applied to feather
points..

page_text: :
Figure 11, Sheet 2, is a side elevation showing apparatus for com-
pensating for contraction and expansion of rods or wires working signals
according to my Invention.
Upon reference to Figure 1, Sheet 1, it will be seen that the points a, a,
and a, a, are formed square and of the same section as the main rail.
The main point a, a, and the branch point a¹, a¹, are bolted together and
linged or jointed to the main and branch line at the heel chair at a², as
shown in the Drawings. The length of rail, being the main point a, a;
and the branch point a¹, a', move together and in unison; they are fitted
in double chairs c moving on suitable guides 6, and having a fixed travel
thercon. They are also where requisite fitted on half chairs, as at c'. In
front of the points and within the guage there are fixed two check or guide
rails d to ensure the certainty of the train taking the points. Between
the check rails & and the main rails I provide a locking apparatus, as
shown at Figure 2. This apparatus consists of a bar of iron e arranged
to receive three movements during the change of the points, namely, a
rising movement, a forward movement, and a falling movement. The
double chairs c carrying the main and branch points a, a, and a¹, a¹, are
connected by a transverse rod f having a pin with an antifriction roller,
as shown at Figure 4, f. The levers working the point locks e are also
connected by a transverse rod e³, as shown at Figure 3, having a pin with
an antifriction roller in its centre e². In the guage and between the rails
there is fitted a sliding plate g, having action parallel with the rails, and
operated by the rods and lever g¹, 93, 9³, under control of the pointsman.
The plate g is fitted with two grooves or slots h, k. Into these slots take
the rollers f¹ and e² on the transverse bars f and e; thus one slot is
connected with the point lock e, and the other is connected with the
sliding chairs c carrying the main and branch points a, a, and a¹, a¹.
The first slot is formed with three distinct directions, namely, diagonal,
longitudinal, and return diagonal, as shown. The second slot h is also
formed with three distinct directions, namely, longitudinal, diagonal, and
longitudinal. Further down and nearer the heel of the combined main
and branch points they are carried on a second set of double chairs c
working on suitable slides 6', and having a fixed travel. These chairs c³.
are connected by a transverse bar i passing over the tail of the sliding
plate g. Upon the under side of the bar i there is a slot or groove i¹ (sec.
Figure 5), which also acts as a lock by taking on to the two horizontal
lugs j,j, formed on the face of the sliding plate g, and having position
relative to the side travel of the points a, a, and a¹, a¹.

page_text: The action of the gear is thus :-The first slot % in the travelling
plate g having a diagonal direction and being in connexion with the point.
lock e the second slot in the plate 9 having a longitudinal direction:
and being in connexion with the points a, a, and a¹, a', and the locking:
lug on the tail of the plate o taking into the groove in the transverse
bar it is evident that by the movement of the plate y three motions are:
obtained, namely, the point lock e is lifted and withdrawn; secondly,
the locking lug on the end of the plate g is withdrawn from the trans-
verse bar i; thirdly, the combined points a, a, and a', a', are free to:
travel and be moved. Upon a further stroke of the plate the slot / has
a longitudinal direction which leaves the point lock in the position
attained by the first portion of the stroke; the slot / however having a
diagonal direction causes the combined main point and branch point
a, a, and a¹, a¹, to travel to the required position by means of actuating
the transverse rod or bar f. In the travel of the combined main point
and branch point the transverse bar i also travels over the face of
the tail plate g and brings the groove opposite the second locking
z¹
lug j. Upon a further stroke of the plate the slot k having a return
diagonal direction causes the point lock e to fall and resume its normal
position, and lock securely the line, namely, for the main, or for the
branch, or as the case may be. In this movement of the plate g the
second slot having a longitudinal direction the position of the combined
points remains unaltered, but the second lug j on the tail of the plate g
is brought into gear with the groove / on the transverse bar i, and in
connexion therewith acts as a further lock.
!
It will be seen by the foregoing that the operation of unlocking,
moving, and locking the points a, a, and a', a¹, is done by one move-
ment of the sliding plate g, which is actuated by the gear g¹, 92, 93, under
control of the pointsman.
i The part of this Invention which relates to actuating and interlocking
the signals will be seen upon reference to Figures 1, 3, 6, and 7, Sheet 1.
,, are two rocking levers, having longitudinal slots at, and quadrant.
ends at these levers are respectively connected with and operate the
signals m, m³, in connexion with the points, namely, the lever is con-
nected to the rod n which operates the signal m for the main line, and
the lever is connected witli a rod n¹ which operates the signal m³ for
the branch line; the levers 7, 1, are respectively provided with longi-
tudinal slots at 1, into which take pins or studs fixed on the travelling

page_text: bar o; the bar o is attached to and worked by the shifting of the points
a, a, and a¹, a¹. The quadrant ends of the rocking levers, 1, 1, work
across the face of the sliding plate p, having a stud or projection p¹, and
so arranged that the said projection p¹ will operate whichever of the
rocking levers 1, 1, may in gear with it, and by this means move the
signal. The rocking levers 7, 1, are prevented from actuating the signals
when not in gear with the projection p' by the lugs p³. The signals
m, m³, for the main and for the branch are by this arrangement worked
by one rod, wire, or its equivalent p² which operates the sliding plate p,
the rod or wire p² being actuated by one lever under the control of the
signalman.

The signalling apparatus just described is interlocked with the point
lock e by providing the rods n, n', connecting the rocking levers 1, 1,
with the signals, with a projection on their under side, as shown at q,
Figure 3, Sheet 1, so arranged that they can respectively be locked or
free according to the position of a transverse bar worked by the point
This transverse bar has cross grooves, as shown at
Figure 3, Sheet 1, so arranged that the projection on the signal rods will
pass through or be locked by it, according to the position of the point
lock e, and when the points a, a, and a¹, a', are unlocked both signals
m, m³, stand, and are locked at danger.
locking apparatus ẹ.
Upon reference to Figures 8, 9, and 10, Sheet 2, it will be seen that
my Invention is also applicable to feather points in manner similar to
that before described for square points. Figure 9 shows a modification
of the point lock e which derives its movement from the action of the
sliding plate g, which by the attendant gear actuates the bar e and locks
the points, as will be understood upon reference to the Drawings.
Upon reference to Figure 10 it will be seen that the locking bar e
works in and is carried by a brackets, which is attached to the rail a as
shown.
. Upon reference to Figure 11, t is a wire connecting the lever u to the
points or signals. This wire t is attached to the sliding toothed rack v
passing over the pulleys w is held tight by the weight x. The wire is
actuated by a pawl y, with a lever and weight y₁ attached to a sliding.
frame, and so arranged that the signalman or pointsman operating the
lever u, the rod z brings the pawl y into whichever tooth of the rack v
which happens to be opposite the said pawl y. It will be seen that by
this arrangement the lever u immediately transmits its motion to the

page_text: point or signal, no matter how much contraction or expansion may have
taken place in the connecting wire or rod t..
Having now fully described and ascertained the nature, object, and
purposes of this my Invention of "Improvements in and Applicable to
Railway Points and Locking Apparatus for same, also in the Means of
Actuating Signals and Interlocking same with the Points, and Compen-
sating for Contraction or Expansion of Rods or Wires Working such
Signals," and shown how the same may be put into practical effect, what
I claim as my Invention and secured to me by Letters Patent as
aforesaid is,

for either branch or main line the signalman can, by the use of one rod,
wire, or its equivalent, actuate either the main or branch line signal, as
the case may be, substantially as shown in the accompanying Drawings
and set forth in the before-going Specification.
Fourthly. The combination of the wire t, the toothed rack v, the
weight x, and the sliding pawl y operated by the rod z and the lever u,
