I, do hereby declare the nature of this invention to be as follows:-
The means of my Invention of an Automatic Railway Coupling, is to enable Engine
Driver or Stocker to uncouple the Engine from the Carriages, or Waggons while
standing on the Engine, by pushing a handle from them, which is fixed upon the
tender to open catches on a Cylinder fixed to Engine. When they wish to couple
they back in and thero is a steel draw-bar in a socket fixed to Carriages or waggons,
which enters cylinder upon Engine, and is cought by two Catches which cant be
unlocked until the levers ar drawn. The arrangement for uncoupling Carriages or
waggons, the Levers will be placed at end of Carriages or Waggons, which will
prevent inen from going between any of the Carriages.

Automatic Railway Coupling.
ROBERT FYFE KERR, Engineer, 60 King Street, Pollokshaws, Renfrewshire, N.B.
do hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This coupling consists of a steel drawbar or drawbars working in a socket or
sockets and of a cylinder or cylinders provided with spring jaws, into which the
disengaged end or ends of the drawbar or drawbars passes or pass on two Engines,
Carriages or Waggons being brought together; the aforesaid spring jaws being
locked or unlocked by a movable collar worked by a handle or handles completely out
of the way of the buffers. Detailed description of which is as follows; A is attach-
ment to Engine, Carriage or Waggon to receive circular end of B which is a steel
drawbar having one end circular and fixed into A and provided with india-rubber
rings to give elasticity when riding round curves, and the other ond tapered to
facilitate entrance into Cylinder C thro spring jaws D. D. and furnished with check to
prevent return. E E are arms with springs attached to force jaws D. D. into former
position after displacement by end of drawbar B. F is a movable collar which by
pressing arms E E down and so opening jaws D. D. releases the drawbar B; or by
being moved and held in position over jaws D. D. securely locks drawbar B.
C Care levers to operate collar F securely fixed to shaft H which works in
bearings I. I. and are operated by handles K. K. fixed outsido buffers.
This coupling can be used as a central buffer being fitted then with a diaphragm
with spiral or indiarubber springs forming a cushion to receive end of drawbar B.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is-
1. This coupling is quite automatic, the collar which locks spring jaws being only
as additional security.
2. This coupling is so arranged that there is sufficient play room to allow riding
round, coupling or uncoupling on any curve.
3. This coupling can also be used as a central buffer, being fitted as herein before
described.
