Complete Specification Left, 24th July, 1893-Accepted, 26th Aug., 1893
PROVISIONAL SPECIFICATION.
Improved Arrangement of Valve Motion (Governing and Reversing)
for Steam Engines.
We, FREDERICK LAMPLOUGH, of The H.A.C. Armoury House, Finsbury,
County of London, Engineer, and JOSEPH AUGUSTUS BAUER, of 22 Appleford
Road, Upper Westbourne Park, Middlesex, Gentleman, do hereby declare the
nature of this invention to be as follows:-
This invention has for object, a special arrangement of rods and levers for
effecting the movement of the slide valve for governing and reversing actions of a
steam piston from the connecting rod.
For the purpose of this invention, a lever is loosely attached to the connecting
rod, and has its opposite end jointed to the valve rod. Between the two joint pins
on the lever, another rod is arranged for motion by quadrant, slotted bar, or its
equivalent for movement by the governor, or by shifting its position the direction
of the valve can be altered for the reversing action.
The invention is specially adapted for single cylinder, or for compound engines.
Dated this 24th dox of Sentember 1892.

COMPLETE SPECIFICATION.
Improved Arrangement of Valve Motion (Governing and Reversing)
for Steam Engines.
We, FREDERICK LAMPLOUGH, of The H.A.C. Armoury House, Finsbury,
County of London, Engineer, and JOSEPH AUGUSTUS BAUER, of 22 Appleford
Road, Upper Westbourne Park, Middlesex, Gentleman, 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:-

on the lever, another rod is arranged for motion by quadrant slotted bar, or its
equivalent for movement by the governor, or by shifting its position, the direction
of the valve can be altered for the reversing action.
The invention will be understood upon referring to the accompanying drawing
in which
Figure 1 is a diagrammatic view of the slide valve connections as operated by
the connecting rod of a steam engine, the single dark and dotted line representing
the relative position of the parts at different points of the stroke.
Referring to the figure, one end of the lever A is loosely attached to the
onnecting rod B, and its opposite end is jointed to the connecting link C of the
slide valve D. Between the two joints before mentioned on the lever A, another
rod E is jointed at the desired distance from the top, said rod E being capable of
movement along the quadrant F to the point a when it is desired to reverse the
direction of motion of the engine. By moving the rod E to or from the centre 6 of

page_text: the quadrant F, any given ratio of expansion or cut off can be obtained, either
under the action of a governor, or by the attendant shifting same by hand.
It will be seen that when the rod E is thrown over to the position indicated by a,
the vibrating arc c is in the reverse direction to that of d, the effect therefore is to
throw the valve D from the position it now occupies to that shown by the dotted
line, so that a lead is given to the other side of the piston G to reverse the direction
of motion of the crank shaft H.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The arrangement of appliances for effecting the motion of valves of steam
engines, as and for the purpose described and shown in Figure 1 of the annexed
drawing.
