PROVISIONAL SPECIFICATION left by the said William Mawlam at the
Office of the Commissioners of Patents on the 8th May 1878.
WILLIAM MAWLAM, of Stockton-on-Tees, in the County of Durham, Blacksınith.
"IMPROVED MEANS OF AND APPARATUS FOR COUPLING AND UNCOUPLING RAILWAY
TRUCKS."
This Invention relates to improved means of and apparatus for coupling and un-
coupling railway trucks, by the use of which the necessity for men going between
the trucks is entirely done away with without any alteration being required in the
trucks or coupling chains at prosent in use. It consists of a cup-shaped clip or
holder made hollow to suit the curve of the end of a link of a coupling chain.
The clip or holder may be of wrought iron or other suitable material fixed on a
suitable shaft or pole which when applied by being passed over the end of one of
the links is held in the hands of the person using it, and the pole may be rested on
the rod of the buffer as a support or fulcrum, or otherwise, as may be most con-
venient.
By the use of this apparatus the coupling chain can be raised to all necessary
positions hooked on to the adjoining truck which it is intended to couple, or hooked
up on to the truck to which the chain is attached. By this apparatus both the
chains on the adjoining ends of two trucks can be attached when required.
For uncoupling trucks the apparatus is applied to one of the links in the same
way, and when the link is lifted off the hook to which it has been attached it may
either be dropped or hooked back on to its own truck, as may be desired,

page_text: The apparatus may either be made with a socket for the reception of a wood
pole or handle, or may be made entirely of iron, steel, or other material with a
tubular or other shaft of the same material attached to it.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Mawlam in the Great Seal Patent Office on the 8th
November 1878.

"IMPROVED MEANS OF AND APPARATUS FOR COUPLING AND UNCOUPLING RAILWAY
TRUCKS."
This Invention relates to improved means of and apparatus for coupling and
uncoupling railway trucks, by the use of which the necessity for men going between
the trucks is entirely done away with without any alteration being required in the
trucks or coupling chains at present in use. It consists of a cup-shaped clip or
holder made hollow to suit the curve of the end of a link of a coupling chain.
The clip or holder may be of wrought iron or other suitable material, but is pre-
ferably of steel, and fixed on a suitable shaft or pole, which when applied by being
passed over the end of one of the links is held in the hands of the person using it,
and the polo may be rested on the rod of the buffer as a support, or fulcrum, or
otherwise, as may be most convenient.
The Invention will be clearly understood by reference to the annexed Drawings,
in which Figure 1 is a side elevation of the apparatus, shewn as applied to the end
link of a coupling chain A, A; the second link B3, B, is shown in section, and the
instrument is passed through the link B, B, and fits on to the end of link A, A.
By the use of this apparatus the coupling chain can be raised to all necessary
positions, hooked on the adjoining truck which it is intended to couple, or hooked up
on to the truck to which the chain is attached. By this apparatus both the chains
on the adjoining ends of two trucks can be attached to the adjoining truck when
required.
For uncoupling trucks the apparatus is applied to the link A, A, in the same way,
and when the link is lifted off the hook to which it has been attached it may either
be dropped or hooked back on to its own truck, as may be desired.
The apparatus is shown in cross section at C, D, E, Figure 1, and in longitudinal
section at Figure 2.
The apparatus may either be made, as shewn, with a socket F for the reception of
a wood pole or handle G, or may be made entirely of iron, steel, or other material,
with a tubular or other shaft of the same material attached to it.
And having now described the nature of my said Invention, and in what manner
the same is to be performed, I declare that I claim, the improved means of and

page_text: apparatus for coupling and uncoupling railway trucks, as hercin-before described,
and substantially as shown in the annexed Drawings.
In witness whereof, I, the said William Mawlam, have hereunto set my hand
and seal, this Fourth day of November, One thousand eight hundred and
seventy-eight.
WILLIAM MAWLAM. (L.S.)
