I RICHARD WATSON MEWES of 29 Durham Road Blackhill County Durham
Locomotive Engine Fitter do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to simplify the management of Locomotive Stationary
and Marine reversing Engines. This is accomplished by confining the attention of
the driver to the Regulator Handle. The usual reversing lever is entirely dispensed
with, the reversing gear being worked from the Regulator Handle. Thus it is evident
that the driver will have his engine under more complete control than when he has
two handles to attend to.
I also claim this advantage for my invention, that it is quicker and more effective
than the usual systems of reversing-being instantaneous in its actions.
Other advantages claimed are; i.e. in case of impending collisions, etc, incidental
to all Locomotives the attention of the driver is not necessarily diverted from the
Regulator Handle as the reversing motions are worked from it.
Again, as in shunting, the driver need not take his attention from his fireman, as
he has not the usual reversing lever to attend to.
It is evident that by my system
danger to life will be considerably reduced.
There is a slot link for working the slide valve with adjusting screws or other
means of reducing the travel of the block, so as to cut off at any portion of the
stroke.
Or the adjustment may be on a lever actuating the block or the slot link itself.
This slot link or block is moved. by a handle acting on the valve, in this way. The
regulator handle being on the centre may be moved to the right or left, giving
forward or backward motion by means of a slide or other valve admitting the steam
to one end or the other of the Reversing Cylinder.
This Cylinder moves the slot link in one way or the other, as may be desired. At
the same time on the spindle of the regulator handle there is a crank which actuates
a valve for the admission of steam to the main or working cylinders, so that the first

page_text: motion of the handle one way or the other first moves the valve open to reverse the
engine. Afterwards, on the continuation of the motion of the handle, the throttle or
regulating valve for the supply of steam is opened according to the amount of travel
of the regulator handle. The reversing cylinder and main cylinders being supplied
with steam from separate steam pipes.

Improvements in and Connected with the Starting and Reversing
of Locomotives and other Engines.
I RICHARD WATSON MEWES of 29 Durham Road Blackhill County of Durham
Locomotive Engine Fitter to 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 :—

In the case of Locomotives there is a slot link for working the slide valve with
adjusting screws or other means of varying the travel of the link, so as to cut off at
any portion of the stroke, or the adjustment may be on a lever actuating the block'
or the slot link itself. This slot link is moved by a handle acting on the valve in
this way, the regulator handle being on the centre may he moved to the right or left
giving forward or backward motion by means of a slide or other valve admitting the

The cataract cylinder may be on a pivot if preferred.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is
1st. The method of working and reversing Engines by means of valves and a
reversing cylinder as described.
2nd. The seperate working and adjustment of the amount of expansion as
described.
3rd. The whole arrangement as described for Locomotive Engines as described.
4th. The whole arrangement for Stationary, Marine and other Engines as described.
