of Waggons Passing over Railways.
We JOSHUA OXLEY of 3 Harlesden Cottages Harlesden Green in the County of
Middlesex Railway Signalman and RICHARD HEWLETT of 31 Essex Street Strand
London Gentleman do hereby declare the nature of this invention to be as follows :-
A globe or round ball is so fixed inside or outside the roadway at any convenient
spot that it can be worked by rods or chains from the Signal box connected with the
Semaphore Signals or points on a gridiron or rocker or slide and so that when tho
signal is at danger the globe or ball is struck by every wheel of a passing engine or
train and made to revolve and in so revolving the globe or ball connected with the
alarm apparatus causes the same to sound and gives the signal. When the signal is
not at danger the globe or ball is removed clear from the rail so that no alarm is given.
The apparatus can by means of rods or chains be so extended as to give warning a
long distance off of an approaching train and may also be used to check the number
of waggons passing over railroads. This apparatus for checking waggons consists of
a ratchet wheel or a roller wound up by a weight fixed in a box and connected with
the rods moved by the revolving globe or ball and with a dial the hand of which is
moved by the ratchet wheel.

We, JOSHUA OXLEY, of 3, Harlesden Cottages, Harlesden Green, in the county of
Middlesex, Railway Signalman, and RICHARD HEWLETT, of 31, Essex Street, Strand,
London, Gentleman, 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 :-
My invention relates, in the first place, to the employment in suitable positions of
bells, gongs, fog horns, or other alarm signals the same being arranged in connection
with mechanism, as hereinafter described, so that they may, when desired, be actuated
or sounded by the action of the wheels of a passing train on the said mechanism.
By means of the alarm signals arranged in accordance with the said first part of this
invention, the necessity for employing detonating fog signals, in the ordinary way, is
obviated, and the liability to overrun danger signals, at night or in foggy weather, as
frequently occurs from the engine driver, while dazzled by the lurid glare from the
fire box, mistaking the red for a white light, is avoided. The second part of this
invention relates to the arrangement in connection with the mechanism, hereinbefore
referred to, of a suitable counting machine, whereby the number of wheels, passing
over that part of the line in connection with which the said mechanism is arranged, is
recorded and the numeration of the traffic thereby readily effected.
The mechanism hereinbefore referred to is arranged, near the inner or outer side of
one of the rails, in such a manner that it may be approached to the rail or moved away
from the same, as desired. The said mechanism consists of a gridiron slide or a
rocker, bell crank, or other lever on which is arranged a globe, or spheroidal or other
similarly rounded surface (hereinafter termed the globe), which globe is so mounted
on a spindle as to allow of its free revolution when struck by a wheel in order to lessen
friction. The normal position of the globe is such that it will be struck by the wheels
of a passing train and the slide or lever on which it is mounted is retained in the
position necessary for this purpose, by its own weight, by a spring or by a counter-
balancing weight. When in such a position, the globe must not be too close to the
rail, but at such a distance that it will be struck lightly by the flanges or by the outer
edges of the tyres of the wheels, the too near approach to the rails being prevented
by suitable stays or stops. On the globe being struck by a wheel the slide is caused
to move back, or the end of the lever is depressed, or pushed aside or elevated as the
case may be which motion is transmitted to the signal by means of rods, chains or
wires or any suitable combination of the same whereby the said signal is actuated or
when the signal is arranged to be actuated by electricity the movement of the slide
or lever is utilised to close an electric circuit in which the signal or signals is or are
placed, as will be well known and understood. The signal is situated so as to attract
the attention of the officials in charge of the train and other signals may also be
arranged, in connection with the said mechanism, at a distance, in order to give notice
of the progress of a train or for other purposes, or the said mechanism may be arranged

page_text: to act on one or more such distant signals only. The slide or lever carrying the globe
can, when desired, be moved clear of the path of the wheel by means of the lever
actuating a signal or point or by a separate lever, through the medium of a chain, rod
or wire.
We will now refer to the accompanying drawings from which the nature of the said
invention will be more clearly understood. The same letters indicate like parts in all
the Figures. Figure 1. is a plan of a portion of a line of way showing the arrange-
ment in connection therewith of the mechanism hereinbefore described, and Figure 2.
is a cross section of the same through the line x. x., in these Figures a gridiron slide
furnished with a globe is shown arranged in connection with one of the rails, and
Figures 3. and 4. are cross sections through that rail, showing respectively the said
slide in, and out of, position for the globe to be struck by the wheels. a. is the slide
which is arranged to move along the guide feathers or ribs shown on the face of the
block b., the said slide is connected with the rod c. one end of which is connected by a
chain to the mechanism for striking the gong d. whilst the opposite end is pivoted to
the lever e. on the shaft f., g³ ³ are weighted levers on the said shaft for the purpose
of automatically retaining the slide a. in close proximity to the rail, the end of a rod h.
is attached to the lever i. for the purpose of utilising the action of the shaft f. for
actuating a recording instrument, the chain k. is shown connected to the arm k¹ for
the purpose of actuating a signal arranged at a distance. When the globe a¹ is struck
by a wheel, the slide a. shoots back on the block b. taking with it the rod c. and thus
actuating the gong d. and rocking or partially revolving the shaft f, this movement
of the said shaft causes the chain k. to be drawn and thus to actuate one or more
signals at a distance, and its action is also communicated through the rod h. to the
recording instrument. In Figures 1. and 2. are shown the lever l. and chains g¹g"
the latter connected with the lever and the former with a suitable hand or other
lever (not shown in the drawings) for withdrawing the slide a. from its position close
to the rail. Figure 5. is a plan view of a portion of the line with the mechanism
hereinbefore described arranged in connection therewith and Figure 6. is a cross
section of the same. In these Figures the globe a¹ is shown mounted on a rocking
lever a, which is pivotted at a³ to suitable bearings, a weight a' is attached to one end
of the lever a² for the purpose of bringing the same to its normal position, the arm a*
of the lever is connected with the rod c. one end of which is connected either directly,
or through the medium of a chain, wire or rod, with the signal to be actuated, and the
opposite end is connected with the lever for moving the globe a from its normal
position, and also, when desired, with means for transmitting the action of the rod to
distance signals and to a recording instrument. The globe a¹ is shown in its normal
position and when struck it assumes the position shown in dotted lines. Figure 7. is
a plan view of a section of a line, and Figure 8. is a cross section of the same.
these Figures the globe a¹ is shown mounted at one end of a lever a which is pivoted
at a. The free end of the said lever a² rests on the cam n., and to an arm on the
axle n¹ of the latter is attached the weight p. in such a manner that after the end of
the lever has been depressed by the action of the wheel and the can partially rotated,
as shown in dotted lines in Figure 9, the said weight after the passage of the wheel will
bring the cam n. and consequently the lever and globe into their normal positions,
an arm on the axle n' is connected with the rod c. In these Figures the spring q. is
shown arranged, for retaining the lever a. in its normal position, as shown in Figure 10.
In the drawings hereinbefore referred to the globe a¹ is shown mounted on a horizontal
axis, but, in some cases, I mount the same on a vertical axis as shown at Figure 11.
the continuation of the lower end of the axis being attached to a slide similar to that
shown in Figures 1. and 2: It will be readily understood that the rods, chains and
wires, for transmitting the action of the slide or lever to the signal or signals, are
arranged in a similar manner to the like contrivances ordinarily employed for actuating
signals and points.
In
The second part of this invention which relates to the recording of the number of
carriages passing over a particular part of the line, is substantially as follows. Tho
lever or slide, carrying the globe a¹ is provided with an arm or similar contrivance

page_text: •
which is so arranged that on each movement, caused by the passage of a wheel, of the
said lover or slide the said arm will actuate the recording instrument, or, the movement
of the lever or slide is made to act on the latter through the medium of a bar, rod,
chain or other suitable contrivance. The said recording instrument may be of any
suitable construction, as, for instance, it may consist of a ratchet wheel or roller wound
up by a weight fixed in a box, the said ratchet wheel being acted upon by the move-
ment of the lever or slide so as to actuate an indicator. When it is desired to employ
this part of the invention the train must pass the globo a' at a slow rate.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is :-
First. The mechanism for actuating railway alarm signals consisting mainly of the
slide or lever a., upon which is mounted the globe a¹ in such a manner that it may bo
brought into position to be struck by the wheels of a passing train, the whole being
constructed and arranged substantially as hereinbefore described.
Secondly. The arrangement, in connection with the mechanism, consisting mainly
of the slide a. upon which is mounted the globe a¹, of a recording instrument, sub-
stantially as, and for the purposes hereinbefore described.
And Thirdly. The mechanism for actuating railway alarm signals and recording
instruments, consisting of the slide or lever a., upon which is mounted, on a horizontal
axis, a globe a the whole being constructed and arranged substantially as hereinbefore
described.
