An Improved Arrangement of Valve Gear for Steam Engines.
1, JAMES KAY, of Phoenix Foundry, Brook Street, Bury, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved arrangement of valve gear for steam
engines whereby 1 economise space and save time and expense in the fitting up and
adjusting of the valve gear.
In carrying my invention into effect 1 employ slide valves and 1 place the valve
gear in a space formed to receive it between the two end chambers in which the
valves work. The valve spindles project into this space and are actuated by a
rocking shaft and a Ramsbottom trip valve gear or other suitable form of trip
gear controlled by connections from the governor, the trip gear and the valve
moving mechanism being contained in the space between the two valve chambers.

1, JAMES KAY, of Phoenix Foundry, Brook Street, Bury, in the County of
Lancaster, Engineer, 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:-
My invention relates to an improved arrangement of valve gear for steam engines
whereby economise space and save tine and expense in the fitting up and
adjusting of the valve gear.
In carrying my invention into effect employ slide valves and I place the valve
gear in a space formed to receive it between the two end chambers in which the
valves work. The valve spindles project into this space and are actuated by a
rocking shaft and a Ramsbottom trip valve gear or other suitable form of trip
gear controlled by connections from the governor, the trip gear and the valve
moving mechanism being contained in the space between the two valve chambers.
In the accompanying two sheets of drawings-
Figure 1 is an elevation and Figure 2 a sectional plan illustrating the valve gear
of a steam engine arranged according to my invention.
In these views, a designates the two end chambers in which the slide valves b
work, and. in the space between which the valve gear is placed. Each valve
spindle c projects through its chamber on one side into the aforesaid space and on
the other into a spring box d the spring of which acts to close the valve. In the

page_text: example illustrated the valve spindles c are actuated to open the valves by a
reciprocating bar or valve mover e, to adjustable arms el on which the spindles c
are coupled by links c'. The bar e is supported in bearings in pedestals and is
reciprocated by a lever g fixed ou a rocking shaft h the lerer y being coupled by
a link to the bar e and connected to the eccentric rod by means of which the
shaft and lever g are oscillated.. Each link e' has a trigger or trip levere formed
with 'or secured to it and these triggers are acted upon by the trip nebs k of the
trip gear which is connected by a rod m to the governor and is actuated and
operates in the usual way well understood..
The plan view, Fig. 2, in addition to the parts already specified shows the steam
cylindern and the ports and passages-n' leading, to and from the same, the exhaust
valves o, their valve rod p and the exhaust passage q.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be' performed I declare that what-I
claim is :-
The improved arrangement of valve gear which consists essentially in placing
the valve moving and tripping gear within a space formed to receive it between
the two end chambers in which the valves work all substantially as and for the
purposes herein described and as illustrated by the accompanying drawings.
