ARTHUR WELLESLEY LAKE, of 66, Gloucester Gardens, Hyde Park, in the County
of Middlesex. "IMPROVEMENTS IN ELASTIC PACKING AND IN VESSELS OR UTENSILS
PACKED WITH THE SAME AND IN THE APPLICATION THEREOF, AND IN MEANS, MODES,
AND PROCESSES CONNECTED THEREWITH." A communication from abroad by
Jacob C. Horton, of the City of New York, and James Brady, of the City of
Brooklyn, United States of America.
This Invention relates to packing for pistons, plungers, rods, and similar working
parts of machines, and is designed to produce a movable tight and frictionless
packing joint not liable to get out of order; the novelty of the Invention consisting
in a rolling or revolving packing free to move over the face of the piston or body to
which it is attached, and compelled to traverse the same by the movement of such
piston or body.
In carrying this Invention into practice the inventors according to one mode of
proceeding make the packing in the form of a flexible ring of india-rubber or other.
suitable material, the external diameter of which is larger than the interior
diameter of the vessel or cylinder it is designed to fit, and the interior diameter of
which is smaller than that of the piston or body it is designed to clasp. The
consequence of which construction is that the packing is always in a state of
compression and extension, and being free to nove it is also in a condition to
always completely fit the space between the piston and the cylinder, and this with
almost no liability to wear and with less tendency to produce leakage by wear than
any other packing. This flexible ring the Inventors prefer to make of metal or of
strong fibrous material, well coated or covered with india-rubber or other pliable
tough yielding and elastic substance of sufficient strength and thickness for the
work to be done. The ring when made and applied is stretched over the piston
and placed upon it in such position that as the piston moves up the ring revolves
and travels down upon it, the outer face of the ring in contact with the interior

-or-in an upward direction.
Another part of the Invention relates to the surface of the piston-or-body-that
moves within the cylinder or stationary vessel; and consists in forming the same
with ridges or corrugations to give a better "bite" to the clastic ring in its passage
over them.
Another part of the Invention consists in the employment of two or more elastic
rings within the same vessel, one-above -the-other, with a body of contained fluid
between the rings.
The inventors propose to apply the Invention to steam, air, and gas engines; to
pumps of all kinds; to water elevators or rams;-to-fluid-meters;-and-to.cylinders
and plungers or pistons for all other apparatus to which the same is applicable; a
part of the Invention consisting in applying the principle or packing to "injection
machines," particularly the kind known as "irrigaterers." In this application of the
Invention a part of the improvement consists in making such machines in the form
of two cylinders, one within the other, with the clastic ring between the two, the
interior cylinder being weighted so as to act upon the body of water underneath
it with sufficient force to propel the fluid without employment of a coiled spring.
