Year: 1847

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDMUND
TATTERSALL, of Newmarket, Land Surveyor, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by. Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland; bearing date at Westminster, the Twenty-first day of
October, One thousand eight hundred and forty-seven, in the eleventh of
year
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Edmund Tattersall, my exors, adñors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said Edmund
Tattersall, my exors, adñors, and assigns, or such others as I, the said
Edmund Tattersall, my exors, admors, or assigns, should at any time agree
with, and no others, from time to time and at all times during the term of
years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "IMPROVEMENTS IN MAKING COMMUNICATIONS FROM ONE PART OF A
RAILWAY TRAIN TO ANOTHER;" in which said Letters Patent is contained a
proviso that I, the said Edmund Tattersall, shall cause a particular descrip-
tion of the nature of my said Invention, and in what manner the same is
to be performed, by an instrument in writing under my hand and seal, to
be inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited

page_text: in its place when in use, and yet they are so formed that supposing a carriage
be required to be removed from a train the cord a would readily be taken
out of the instruments c, c, and a carriage might then be moved away, and
then when the train is contracted in length the spring apparatus 6 would
immediately take up the slack of the cord or instrument a; and in case it
be desired to introduce a carriage into any part of the train, the train would
be divided so as to allow of another carriage being introduced, and this would
be done by running such additional carriage on to a turn-table, and then
turning it into position, and the carriage would then be coupled up to the
two parts of the train, and the cord would be at once placed into the rings c, c,
on the newly introduced carriage; and it will readily be understood that in
dividing a train and separating the two parts the cord or instrument a will
be drawn out, and thus be ready to be introduced into the instruments c, c,
of the newly introduced carriage, when that carriage has been brought into
position.
Although I believe the instruments c, c, Figures 2 and 3, to be best for
obtaining the result above explained, I do not confine myself thereto so long
as the apparatus for retaining the cord or instrument a in place on the
carriages be such as to allow of the cord being removed without drawing it
out longitudinally. And in cases where luggage is carried on the tops of the
carriages, I prefer that the cord or instrument should be covered or housed.
This may be conveniently accomplished by having a split tube fixed to the
carriage, so that the cord may be introduced laterally, and at intervals to
have springs or other stops across the split or opening of the tube, so as to
insure the cord or instrument a being held in the tube. And I would also
state, that although I have shewn the apparatus to be applied at the tops of
the carriages, that is not an essential condition; but I believe that the position
shewn is the best for applying the apparatus. Whatever be the position,
however, of the apparatus, it is essential to the Invention that a carriage may
be introduced or taken out of a train in the manner above explained,
and the cord or instrument a placed in position without requiring to draw
the same longitudinally through the rings or apparatus c. There should be
a suitable socket or holder for the stem of the instrument b, so that,
whichever be the hindermost carriage, or the last carriage on which a guard
rides, the apparatus may be applied thereto, by which means, should it be.
desired to lengthen a train by adding a carriage or carriages to the hindermost
one, and then to carry the apparatus 6 to the end of the train, the cord or
instrument a drawing out or unwinding as it is carried back, and such cord or
instrument will then readily be introduced into the apparatus c.

page_text: Figure 4 shows a plan in section, Figure 5, a front view in section;
Figure 6, a front elevation, and Figure 7 an end view in section, of the appa-
ratus b, which consists of a barrel 6 to wind on the cord or instrument a, as
shewn. This barrel. receives motion by means of a spring in the barrel 62, on
which is a cog wheel 63, which takes into and drives the pinion 6 on the
axis 65, on which is a cog wheel 6º, which takes into and drives the pinion on
the axis of the barrel b'. It will therefore be evident that the spring in the
barrel 62 will at all times keep the cord or instrument a tight, and the un-
winding of the cord will wind up the spring. The cord or instrument a passes
out through the slit or opening &', as shown, and is a handle by which to
carry instrument b. I would remark, that the arrangement of the details of
the apparatus 6 may be varied, but I believe the arrangement shown, will be
found to be as convenient as any other. And I would observe, in respect to the
first part of my Invention, that I do not claim any of the parts or instruments'
separately, this first part of my Invention consisting of combining mechanical
instruments or parts into apparatus for communicating between one part of a
railway train and another, as explained. And it will only be desirable further
to state, that when either of the guards wishes to communicate by signal to the
engineman, he will pull the cord'or instrument a.

I will now describe the second part of my Invention, which consists of
apparatus for enabling a passenger in a carriage to give a signal to a
guard.
Figure 8 is a side view in section, and Figure 9 an end view; of apparatus'
according to this part of my Invention. On the roof of a carriage is placed
a lantern e, having two flaps f, f, at the front and back, so that when they are
down the light of the lamp in the lantern cannot be seen in either direction.
These flaps have a tendency to fly open by springs g, g, when they are permitted
so to do, but the flaps are held down by catches h; h, and the catches can be acted'
on by a passenger by means of the cords i, i, passing into the carriage. On
the inner surfaces of the flaps are painted any device which will readily
be seen by daylight, so that their being thrown open will indicate that
a passenger in that particular carriage requires to communicate with the
guard.
Having thus described the-nature of my Invention, I would have it under-
steed that what I claim is,-
First, the mode of combining parts a, b, c, into an apparatus for making
communications from one part to another of a railway train. And I claim
the mode of constructing and combining the parts a, c, that a carriage may
be taken out from or introduced into a train without requiring that the

page_text: b
instrument a should be drawn longitudinally through the instruments c. And
I claim the arrangement or combination of the apparatus 6 for aiding commu-
nications between parts of railway trains. And,
Secondly, I claim the application of the apparatus described in respect
to Figures 8 and 9, for facilitating communications between parts of railway
trains.
In witness whereof, I, the said Edmund Tattersall, have hereunto set my
hand and seal, this Nineteenth day of April, in the year of our Lord
One thousand eight hundred and forty-eight.
Enrolled the Twentieth day of April, in the year of our Lord One
thousand eight hundred and forty-eight.
