IMPROVEMENTS IN PERMANENT WAY OF RAILWAYS for
Year: 1874

page_text: LETTERS PATENT to William Fothergil Batho, of Westminster, for
the Invention of "IMPROVEMENTS IN PERMANENT WAY OF RAILWAYS."
-A communication from abroad by Bradford Leslie and Guildford
Molesworth, of Calcutta, India.
Sealed the 19th February 1875, and dated the 20th August 1874.
PROVISIONAL SPECIFICATION left by the said William Fothergil
Batho at the Office of the Commissioners of Patents, with his
Petition, on the 20th August 1874.
I, WILLIAM FOTHERGIL BATHO, of Westminster, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN PERMANENT WAY
OF RAILWAYS," a communication to me from abroad by Bradford Leslie
and Guildford Molesworth, of Calcutta, India, to be as follows :-
-
Improved Double Keel Joint for Flanged Rails.-This joint is
intended to supersede the fish joint ordinarily employed at the joints of
flanged rails on railways. It consists of a pair of iron or steel angle
brackets. These brackets when placed together back to back-form-
annroximately a T shaned section.

page_text: The upper portion of each bracket is rolled with a tapered groove,
which will fit the lower flange of the rail in such a manner that when
the two brackets are drawn together the grooves press on the bottom
and inclined portion of the flanges so as to wedge the rails tightly
against the upper surface of the brackets, and thus hold them firmly,
leaving however a clearance for further adjustment should corrosion or
wear and tear render such adjustment necessary.
The backs of the brackets, when the rail is so clipped, must not be in
contact with each other at the top, but sufficient clearance must be left
for drawing the brackets together if necessary.
The lower edges of the vertical portion of the brackets may or may
not be formed with projecting fillets or flanges to afford a lower fulcrum
or bearing surface if required to balance the strain on the bolts necessary
to secure the rails firmly. These fillets or flanges on the lower edge
may or may not be rolled with recesses to permit the escape of sand or
dirt from between the brackets.
The vertical portion of the bracket may if necessary be inclined to any
suitable angle.
The brackets are placed below the bottom of the rail in such a
position that the grooves clip the flanges of the rails; the brackets are
then drawn together by means cither of screw bolts or rivets, or cottered
bolts, or by other suitable means until the rails are firmly held.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Fothergil Batho in the Great Seal
Patent Office on the 20th February 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
FOTHERGIL BATHO, of Westminster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria by Her
Letters Patent, bearing date the Twentieth day of August, in the year
of our Lord One thousand eight hundred and seventy-four, in the 3
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Fothergil Batho,.

page_text: The upper portion of each bracket is rolled with a tapered groove B, B',
which will fit the lower flange of the rail in such a manner that when
the two brackets are drawn together the grooves press on the bottom
and inclined portion of the flanges so as to wedge the rails tightly
against the upper surface of the brackets, and thus hold them firmly, 5
leaving however a clearance for further adjustment should corrosion or
wear and tear render such adjustment necessary.
The backs of the brackets, when the rail is so clipped, must not be in
contact with each other at the top, but sufficient clearance must be left
for drawing the brackets together if necessary.

The lower edges of the vertical portion of the brackets may or may
not be formed with projecting fillets or flanges C, C', to afford a lower
fulcrum or bearing surface if required to balance the strain on the bolts
necessary to secure the rails firmly. These fillets or flanges on the
lower edge may or may not be rolled with recesses to permit the escape 1
of sand or dirt from between the brackets.
The vertical portion of the bracket may if necessary be inclined to any
suitable angle.
The brackets are placed below the bottom of the rail in such a
position that the grooves clip the flanges of the rails; the brackets are 2
then drawn together by means either of the screw bolts or rivets, or
cottered bolts, or by other suitable means until the rails are firmly
held.
Having now described the nature and particulars of the said Inven-
tion, I claim the Improvements in the Permanent Way of Railways, 2
substantially as herein described.
In witness whereof, I, the said William Fothergil Batho, have
hereunto set my hand and seal, this Eighteenth day of February,
One thousand eight hundred and seventy-five.
