in the County of Surrey. "IMPROVEMENTS IN STEAM OR OTHER FLUID MOTOR
ENGINES OR PUMPS."
My Invention relates to steam or other fluid motor engines in which a reci-
procating piston gives rotation to a crank, or to pumps in which a rotating crank or
eccentric gives reciprocating motion to a piston or bucket, and has for its object the
simplification of the connection from the piston to the crank or eccentric. I joint
directly to the piston a connecting rod which passes through a rocking and sliding
joint in the cylinder cover and is jointed to the crank. The joint on the cylinder
As the crank revolves
cover is packed so as to be tight against the leakage of fluid.
-
and the piston reciprocates the connecting rod moves through the joint, taking at
the same time the inclination and deviation from the axial line required by the
circular movement of the crank, and permitted by the rocking and sliding joint on
the cylinder cover. The piston may be guided by rods passing through the covers
so as to diminish the lateral strain, or the piston itself may be made of more than
the usual depth for the purpose of steadying it against the lateral strain and
increasing the rubbing surface.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Francisco de Camargo Pinto in the Great Seal Patent Office on the
30th June 1877.

page_text: My Invention relates to steam or other fluid motor engines in which a reci-
procating piston gives rotation to a crank; or to pumps in which a rotating crank or
eccentric gives reciprocating motion to a piston or bucket, and has for its object the
simplification of the connection from the piston to the crank or eccentric. I joint
directly to the piston a connecting rod which passes through a rocking and sliding
joint in the cylinder cover and is jointed to the crank. The joint on the cylinder
cover is packed so as to be tight against the leakage of fluid. As the crank revolves
and the piston reciprocates, the connecting rod moves through the joint, taking at
the same time the inclination and deviation from the axial line required by the
circular movement of the crank, and permitted by the rocking and sliding joint on
the cylinder cover. The piston may be guided by rods passing through the covers
so as to diminish the lateral strain, or the piston itself may be made of more than
the usual depth for the purpose of steadying it against the lateral strain and
increasing the rubbing surface.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents a longitudinal section of a cylinder, such as that of a steam
engine with elevation of its piston and connecting rod, the latter working through
a rocking and sliding joint in the cylinder cover according to my Invention; Fig. 2
is a transverse section, and Fig. 3, a front view of the said joint.
The connecting rod A which is jointed at one end to the piston B, and at the
other end works on the crank pin C, passes through a stuffing box D of spherical
form, which works in bearings in a slide E fitted to move in guides F on the
cylinder cover in a line parallel to the plane in which the crank revolves. The
piston B may be made of considerable depth, or it may be guided on rods G to take
the lateral strain. It will be seen that as the crank revolves the connecting rod
while it slides through the stuffing box D can also take the angle and direction
required to accommodate it to the circular path of the crank pin.
It is obvious that the construction of the stuffing box and slide may be varied
without departing from the principle of my Invention.
Having thus described the nature of my Invention and in what manner the same
is to be performed, I claim, directly connecting a reciprocating piston to a crank or
eccentric by a connecting rod passing through a rocking and sliding joint on the
cylinder cover, so arranged as to allow for the inclination and deviation of the rod
as it follows the path of the crank or eccentric, substantially as herein described.
In witness whereof, I, the said Francisco de Camargo Pinto, have hereunto
set my hand and seal, this Twenty-first day of June, in the year of our
Lord One thousand eight hundred and seventy-seven.
