the County of Middlesex, for the Invention of "AN IMPROVED LIFTING JACK
FOR RAILWAY PURPOSES." A communication from abroad by Mr. Emile Manier,
of Montpellier. France, Contractor.
ed the 22nd August 1876, and dated the 16th March 1876.
PROVISIONAL SPECIFICATION left by the said William Lloyd Wise at the
Office of the Commissioners of Patents on the 16th March 1876.
WILLIAM LLOYD WISE, of Chandos Chambers, Adelphi, in the County of
Middlesex. "AN IMPROVED LIFTING JACK FOR RAILWAY PURPOSES." A com-
munication from abroad by Mr. Emile Manier, of Montpellier, France, Contractor.
This Invention has reference to an improved lifting jack suitable for lifting rails,
and for use in repairing and maintaining iron ways.
Upon suitable framing is mounted a box or case containing wheel gear actuated
by handles and a pinion so as to give vertical notion to a rack whose lower end
carries a self-acting clip or pair of tongs so arranged as that when lowered the
tongs on coming in contact with the head of the rail to be raised shall open, and
after having been sufficiently lowered shall, on the rack being moved upward, clip
and hold the rail so as to raise the same and hold it up as required whilst the
packing of the sleeper or other needful operation is performed. A rod is provided
for opening the tongs clear of the rail when the latter has been lowered, and the
apparatus is constructed with arms or handles jointed to it, by which arms or
handles the apparatus may be carried about. When the apparatus is in use these
arms or handles lie in a downward direction to be out of the way.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Lloyd Wise in the Great Seal Patent Office on the 1st
September 1876.

page_text: This Invention has reference to an improved lifting jack suitable for lifting rails,
and for use in repairing and maintaining iron ways.
Upon suitable framing is mounted a box or case containing wheel gear actuated
by handles and a pinion so as to give vertical motion to a rack, whose lower end
carries a self-acting clip or pair of tongs, so arranged as that when lowered the tongs
on coming in contact with the head of the rail to be raised shall open, and after
having been sufficiently lowered shall on the rack being moved upward clip and
hold the rail so as to raise the same and hold it up as required whilst the packing
of the sleeper or other needful operation is performed. A rod is provided for
opening and raising the tongs clear of the rail when the latter has been lowered,
and the apparatus is constructed with arms or handles jointed to it, by which arms
or handles the apparatus may be carried about. When the apparatus is in use
these arms or handles lie in a downward direction to be out of the way.
In the accompanying Drawing, Figs. 1 and 2 are respectively a front view and
an end view of the improved jack; F is a double iron frame whose lower part is
provided with two feet P, P, having between them the necessary space for the
rail C to allow of its being raised. On the upper part is fixed the box V of the
lifting jack, in which are carried the toothed wheels and pinions of ordinary con-
struction, as shewn, as also the upper end of the rack V₁ whose lower end carries
the self-acting clip or pair of tongs B, B. The working of this apparatus is very
simple. By means of the handles A, A, the jack is lowered, and the tongs B, B,
on coming in contact with the head C of the rail will, owing to their peculiar shape,
naturally separate until they get below the head of the rail, whereupon they will
engage with it; it suffices then to raise the jack with the rail to just the point
desired, and to fix it at that point by means of the pawl. The two men who
operate, one at each handle, may now release their hold and work on the packing
of the sleeper. The sleeper having been packed the jack is lowered and the rod D
is raised, and this causes the tongs to open so as to clear the head of the rail. The
arms or rods E, E¹, E", E, are pivotted so that a couple of men may raise
the apparatus from the ground and carry it from place to place. These rods
are shewn lowered in Fig. 1, and in Fig. 2 are raised into position for carrying the
apparatus. A sight vane is placed at the axis of the rack, it plays between two
Bashes adapted to the frame, and its lower extremity forms a T rest upon the rail;
it serves to stop the raising at the desired point. (This vane may be raised by
ineans of two screws which hold it at its upper part).
As will be evident the apparatus, besides being extremely simple, presents great
advantages, being productive of considerable economy of hand labour, since two
men with the apparatus may do the same work as would require six men working
with the ordinary crow bar, and this without any accident or uneasiness.
The form of the tongs may obviously be modified to suit the form of rail to be
raised and lowered.
Having described the nature of the said Invention, and the manner of performing
it, as communicated to me as aforesaid, I hereby declare that what I consider to be
novel and original and therefore claim as the Invention secured to me by the
herein-before in part recited Letters Patent is, the combination of parts constituting
the improved lifting jack for rails; constructed, arranged, and operating as herein-
before described and shewn in the accompanying Sheet of Drawings.
In witness whereof, I, the said William Lloyd Wise, have hereunto set my hand
and seal, this First day of September, in the year of our Lord One thousand
eight hundred and seventy-six.
W. LLOYD WISE. (L.S.)
