PROVISIONAL SPECIFICATION
Improvements in Fluid-pressure and other Engines.
BRICE HENRY BUDDING, Jr., 1, Addington Road, Canning Town, London, E.,
Engineer, do hereby declare the nature of this invention to be as follows:-
Method by which a single cylinder or other engine can, he made, to start at any
position of the crank, & work without a fly wheel; & if two cylinders, cranks
to be placed at 180° to each other.
I use a jointed connecting rod (mid, or otherwise) to this joint is attached the
ends of two radius rods, one on either side: the other ends of these having a
slot link, with a gab at their inner ends, & which work on pins or a shaft, fixed
to the cylinder standards, forming the centres, these ends being put in & out of
gear, as required to run the engine inwards or outwards, by lever.

Improvements in Fluid-pressure and other Engines.
I, BRICE HENRY BUDDING, Junior, of 1, Addington Road, Canning Town,
in the County of London, Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
This invention relates to fluid pressure engines of the kind in which single
cranks or double cranks arranged at 180° to each other and actuated by connecting
rods are employed and has for its object to so construct them that when the
cranks are on the dead centre the engine can be readily started without the
employment of any extraneous or auxiliary mechanism.
In carrying out the invention I form the connecting rod or rods in two parts
jointed together and connect to the joint the inner ends of two radius rods one
on either side thereof, the other ends of which rods are arranged in such a manner
that one can be fixed and the other allowed freedom of movement. This may
be effected by providing the said ends with slot links witli a gab at their inner
ends, the said slot links working on fixed pins or the like and being put into
and out of gear as required by a lever or the like. Or the radius rods can be
jointed to sliding blocks with which engage the slotted ends of bars in connection
with lever mechanism whereby they can be operated to lock the block and radius
rod and allow the otlier block to run in its slotted end.
To enable the invention to be fully understood I will describe it by reference
to the accompanying drawings, in which:-

page_text: Figure 1 is an elevation of a portion of a single crank reversing steam engine
having my improvements applied thereto; and
Figure 2 is a horizontal section on the line 2-2 Figure 1.
Figure is a view illustrating the arrangement where slot links having gabs
are employed, and drawn to a smaller scale than Figures 1 and 2.
a is the power cylinder and the base plate of the engine. c, c are columns
for supporting the cylinder on the base plate; is the crank shaft, e the crank, f
the slide block, y, g the eccentrics, h, the eccentric rods, the slide valve
spindle, the reversing link and the reversing lever, the said lever being
mounted on the rock-shaft / and actuating the link į through the medium of the
leyers m, m and links o, o. All the foregoing parts are of well known construction.
P Pare the two parts forming the connecting rod and is the joint between
the said parts.. are the two radius rods, which are jointed at the inner ends
to the part of the connecting rod at g', q' and at the other ends are arranged
so that one can be fixed and the other allowed freedom of movement. In the
arrangement shewn in the drawings I effect this as follows, that is to say, I joint
the said ends to blocks s, s' designed to slide on rods, t, t, held in
brackets 1, 2, connected to the columns c, c and I provide the said blocks with
pins u, engaging slots, in bars, we connected by links, to levers y, y
on the rock-shaft 7; the bars are in such a position relatively with the revers-
ing lever that in the extreme positions of the latter one or the other of the
blocks will be held against movement by being forced by the inner end of
one of the pairs of slots bearing against the pins therein and holding the
said block against the bracket 2 carrying the rods or ¹ of the said block; the
other block will at the same time be free to slide along its rod for and the
pins thereon in the slots e, to allow of the movement of the connecting rod.
By this construction it will be seen that, assuming the reversing gear to be
set for the shaft to turn in the direction of the arrow Figure 1 and the crank
to be on a dead centre, that is to say, in alignment or thereabouts with the part pl
of the connecting rod, the blocks will be held in position at the outer end of the
rod as shewn while the block will be free to slide on the rods. By now
operating the lever to reverse the engine the bars we, we will be moved to slide
the blocks and to the other ends of the rods, whereby the blocks will be
free to slide, the blocks held in position and the connecting rod parts P, P
moved to assume an angular position on the other side of the centre line of
the engine and relatively with the crank, and sufficient to enable the crank to
be moved by the said connecting rod under the pressure of steam in the cylinder à.
The engine having been moved can again be stopped and, assuming the parts
stop in a favourable position, again be reversed and run in the direction required.
Instead of the arrangement of blocks s, a¹ rods, and slotted bars wo, w.shewn
in Figures 1 and 2 I may as shewn in Figure 3 form the outer ends of the radius
bars r,
pl with slot links, having gals e, at their inner ends and which
work on fixed pins, or the like, the said ends being connected to the reversing
lever so as to be put into and out of gear in order to hold the end of one radius rod
whilst allowing the other to work free in a similar manner to that just described.
Although I have described my invention as applied to a steam engine it will
be obvious that it can be equally well applied to other fluid pressure engines
öperated in a similar manner.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed; I declare that what
I claim is
1. In a fluid pressure engine of the kind described, a connecting rod formed
in two parts jointed together and to radius rods on each side thereof in com-
hination with means for fixing the outer end of either radius rod and allowing
freedom of movement for the outer end of the other radius rod, substantially as
described.

page_text: 2. In a fluid pressure engine of the kind described in Claim 1, the employment
of blocks jointed to the said radius bars and designed to slide on fixed rods and
having pins engaging slots in bars connected to the reversing lever, substantially
- as described:
3. The improved steam engine constructed, arranged and operating substan-
tially in the manner hereinbefore described and as illustrated in the accompany-
ing drawings.
