the piston will be cut off when the piston has
completed the proper portion of its stroke,
permitting the steam within the cylinder to
act expansively in the well-known manner.
5 Having thus described my invention, what
I claim as new is-
1. In a rotary engine, the combination, with
the rotary piston and oppositely-arranged
movable abutments, of the oppositely-ar-
to ranged reversing and exhaust valves having
passages therein for the live and exhaust
steam and connected to work in unison, sub-
stantially as described.
2. In a rotary engine, the combination, with
15 the rotary piston and oppositely-arranged
movable abutments, of the oppositely-ar-
ranged reversing-valves connected to work
in unison and having passages through the
same at substantially right angles for the
o0 live and exhaust steam, arranged and com-
bined for operation substantially as de-
scribed.
3. In a rotary engine, the combination, with
the rotary-piston and cylinder having a mov-
25 able head, with recesses in said piston and
cylinder, of the removable blocks fitting in
said recesses and the movable abutment piv-
oted in said block, substantiallyas described.
4. In a rotary engine, the combination, with
30 the rotary piston, of the sliding abutments
pivoted in removable blocks dovetailed in
the casing, substantially as described.
5. In a rotary reversible engine, the combi-
nation, with the rotary piston, oppositely-ar-
35 ranged reversing-valves, and corresponding
movable abutments with steam-ports on each
side of the same, of the cylinders in commu-
nication with the valve-chambers, the pistons
working in said cylinders and connected to
to the abutments for keeping the same pressed
out, substantially as described.
6. In a rotary reversible engine, the combi-
nation,with the rotary piston, reversing-valve,
and movable abutment having steam-ports
45 on each side of the same, of the cylinder hav-
ing a single port, which is in communication
with the steam-supply, a piston working insaid cylinder, and a link connecting said pis-
ton and movable abutment, whereby the abut-
ment is held in at all times, substantially as 50
described.
7. In a rotary engine, the combination, with
the cylinder having the movable abutments
pivoted in blocks dovetailed therein, of the
rotary piston having the movable abutments 55
pivoted in blocks dovetailed in the wall of
the piston, substantially as described.
8. In a rotary engine, the combination, with
the rotary piston and sliding abutments, of
the valve havingthe passages passing through 60
the same at right angles and the packing for
defining the chambers with which said pas-
sages open, substantially as described.
9. In a rotary engine, the combination, with
the rotary piston and movable abutments, of 65
the reversing-val.ves formed of the cylinders
having the ports through the same for the pas-
sage of steam, said cylinder fitting loosely
within the valve-casing, and the packing lo-
cated in seats in the cylinder between the 70
ports, whereby chambers are formed into
which the ports open, and ports for opening
communication between said chambers and
engine cylinder or exhaust, substantially as
described. 75
10. In a rotary engine, the combination,
with the rotary piston, movable abutments,
and diametrically-opposite reversing-valves
connected for simultaneous movement, of the
rotary cut-off valves, one in the supply to 80
each reversing-valve, the rod connecting said
valves, and a crank-connection between said
rod and engine-shaft, substantially as de-
scribed.
11. In a rotary engine, the combination, 85
with the cylinder and rotary piston, of the
movable abutments, the blocks in which they
take their bearings recessed into the cylin-
der, and the wedges for tightening said
blocks, substantially as described.
