I, CHARLES DENTON ABEL of N° 28 Southampton Buildings Chancery Lane
in the County of Middlesex, Consulting Engineer and Patent Agent do hereby
declare the nature of the said Invention for "AN IMPROVED APPARATUS FOR
RAISING RAILS ON THE PERMANENT WAY OF RAILWAYS" to be as follows:-
This improved apparatus is intended to replace the inconvenient lever and
windlass arrangement heretofore used for raising the rails on the permanent way
of railways. Figs. 1, 2 and 3 of the accompanying Drawings shew respectively an
elevation, a plan and a section of the said apparatus.
A framing e carries a horizontal shaft w. on which are two eccentrics d d,
connected to each other at different points of the periphery by rods o p q. The
shaft also carries a worm wheel cin gear with which is a worm b, that can be
rotated by a key with hand wheel o.
In operating with the apparatus, the framing is imbedded in the permanent way
(resting if necessary upon a length of rail or bar x) immediately beneath the rail
to be acted upon. On turning the eccentrics by means of the worm and worm
wheel, one or other of the rods o p q is made to bear against the underside of the
rail so as to lift it to the required extent.
The apparatus is made of such dimensions that, on removal of the key, it offers
no obstruction to the passing of a train.

I, CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane
in the County of Middlesex, Consulting Engineer and Patent Agent, do hereby
declare the nature of my said Invention for AN IMPROVED APPARATUS FOR
RAISING RAILS ON THE PERMANENT WAY OF RAILWAYS" and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
This improved apparatus is intended to replace the inconvenient lever and
windlass arrangement heretofore used for raising the rails on the permanent way
of railways. Figs. 1, 2 and 3 of the accompanying Drawings shew respectively an
elevation, a plan and a section of the said apparatus.
A framing e carries a horizontal shaft w on which are two eccentrics d d,
connected to each other at different points of the periphery by rods op g. The
shaft also carries a worm-wheel c in gear with which is a worm b that can be
rotated by a key with hand wheel a.
In operating with the apparatus, the framing is imbedded in the permanent
way, (resting if necessary upon a length of rail or bar ) immediately beneath the
rail to be acted upon. On turning the eccentrics by means of the worm and worin
wheel, one or other of the rods o p q is made to bear against the underside of the
rail so as to lift it to the required extent.
The apparatus is made of such dimensions that, on removal of the key, it offers
no obstruction to the passing of a train.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed, I declare that what
I claim is:-
Apparatus for raising rails consisting of eccentrics d d fixed on a shaft w which
is turned by worm gearing, so that rods o p q connecting the eccentrics raise the
rails as they move under them, substantially as herein described.
Dated this 3rd day of September 1884.
