I, ROBERT LOVELY, of Adam Street, Adelphi, in the County of Mid-
dlesex, Civil Engineer, do hereby declare the nature of the said Invention
for "CERTAIN IMPROVEMENTS IN THE APPLICATION OF STEAM TO THE PRO-
PULSION OF CARRIAGES ON COMMON ROADS, PARTS OF WHICH IMPROVEMENTS
ARE APPLICABLE TO THE CONSTRUCTION OF CARRIAGES FOR COMMON ROADS,"
to be as follows:-
The principal features of the first part of this Invention are the entire
disconnection of the power with the bearing wheels on which the body
of the machine is set by springs, as in the ordinary road carriages, and the
general combination of the parts, as shewn in the Drawing, and hereafter
referred to. In the accompanying Drawing No. 1, represents an eleva-
tion of an engine or machine for propelling carriages with my improve-
ments adapted thereto, and is shewn connected to No. 2, an clevation
of a carriage or vehicle for passengers on common roads, also having my
improvements in the construction exhibited on it. No. 3, is an cnd
clevation or front view of the machine. The power is applied to a

page_text: wheel placed between the trailing wheels, as shown at A, and it is set.
in a frame from B, to C, which frame works upon an axis at B, and
through a slide at C. To give motion to this propelling or driving
wheel the ordinary steam cylinders and connecting rods are set on the
frame before mentioned, which receives a radial motion from the steam,
which is conducted from the boiler and from the cylinders by means of
pipes worked through the ordinary stuffing-box joints; the valve reversing
and pump gearing is attached to the body of the machine, and worked
by a slide rod or lever from the cylinders on the frame. The driving
wheel may be weighted, or altogether lifted off the ground at the will
of the comptroller, by means of an ordinary steam cylinder set in the
case marked D, and connected with the frame in which the wheel is
set by a connecting rod, shewn in dotted lines at No. 1. The course of
the machine is directed by the aid of steam through a cylinder placed
in the fire-box at G, in connection with the vertical rod marked M,
which controls tho fore wheels of the machine. On the rise of the
piston the wheels are caused to turn in one direction, and on the descent.
of the piston they are caused to turn the opposite direction. The speed
may be increased or diminished, and is altogether governed and re-
gulated by means of the guide rod, as shewn, in the hand of the comp-
troller, which is connected with the valve that regulates the motion of
the cylinders. The cooling of the steam is effected before passing from
the cylinders to the chimney by passing through a cavity within the
space marked H, I, J, K, the plates forming such space being of per-
forated metal. Another novelty in this machine, and which also relates
to my improvements in the passenger carriage, is the adaptation of a
spring as the blade of the break, as shewn at L.
The second part of this Invention relating to my improvements in the
construction of carriages on conimon roads is as follows:-At No. 2, will
be seen an elevation of one such carriage according to my arrangements.
A peculiar feature in these arrangements being the form and construction
of the axles, which consist of two plates of boiler-plate iron, placed at a
small distance apart, and secured by bolts and nuts: these bolts are
formed with shoulders to maintain uniformity of distance between the
plates; these plates overlap each other at the ends, and are rivetted

page_text: together, as shewn in end elevation No. 3, at D, and E; the arms or
portions of the axle trec passing through the box of the wheel are formed
of iron, round and shouldered, and they pass through a hole at the lap
of the plates, and are screwed in the inside of the plates by nuts screwed
thereon. For the purpose of oiling the axle arms holes are drilled
longitudinally through them, and also holes in connection therewith and
at right angles thereto in the parts passing through the box. In con-
nection with the longtitudinal holes oil cups are placed, as shewn at
B, C, No. 3. For the purpose of suspending the fore part of the car-
riage on the axle, as shewn at No. 3, one spring is used, and is placed
at right angles to the longitudinal line of the carriage and within the
plates forming the axle, as before described, being set in said plates on
an axis, as shewn, at the point A. The improved arrangements of the
break, as before referred to at No. 1, is also seen at B, No. 2. The
peculiar configuration and arrangements of the passenger carriage is
also a novelty, and is fully illustrated in the accompanying Drawing.
