page_text: 101s Invention has for its object an improved rotary engine applicable as a pump,
exhauster, or blower.
My invention consists of a circular casing containing a drum mounted
eccentrically thereto.
This drum is provided with an axis at the one side passing through the cover or
casing of one side of the cylinder.
This drum is provided with a lateral opening or openings of a width equal to the
diameter of the rollers I employ, and which act as pistons.
I am aware that rollers have heretofore been employed in connection with
rotary pumps and driven by the inner drum in a loose manner and entirely
dependent upon speed in order that the roliers may follow and bear on the inner
periphery of the cylinder by centrifugal force only.
Now according to my invention 1 cause the roller or rollers to assume the circle
of the cylinder by mechanical means, by attaching to the one cover (opposite to
that carrying the spindle of the drum) a pin or roller in the centre thereof and of
the cylinder. The openings in the eccentrically mounted drum are extended a
short distance towards the centre of the druin, to a distance say equal to the
maximum distance between the drum or carrier and the inner periphery of the
casing or in other words the greatest area of the cylinder.
The guides are open to the centre and not in any case continued to the centre
but are of such a length as during rotation to run perfectly clear of the centre or
guiding roller (or pin) upon which the rolling pistons always bear as well as on
the interior of cylinder, thus reducing friction to the minimum as all the parts
rotate.
In some case the rollers may be contained in frames but I have found that the
method already described is most advantageous both in simplicity and fewness of

page_text: parts, not liable to clogging when pumping oils or other material and capable of
working at any speed at which it may be driven.
The cylinder is provided with suitable inlet and outlet, and may be provided
with a valve or valves as required when used as a pump. When used as a steam,
fluid, or explosive motor, suitable valves would be attached and arranged for the
admission of power to the cylinder such as by a rotating valve actuated from the
axis which is that of the eccentrically mounted drum.
Several of the aforesaid drums may be of such a width as to carry several rollers
in series each running in their respective grooves.

An Improved Rotary Apparatus Applicable as a Pump, Motor,
Exhauster, or Blower.
I, JAMES FREDERICK PHILLIPS, of 62, Holborn Viaduct, in the County of
Middlesex, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention has for its object, an improved rotary apparatus applicable as a
pump, motor, exhauster or blower, or as a meter for measuring water, and consists
of a cylinder containing a drum mounted eccentrically thereto, as shown in sectional
elevation at Fig. 1; and at Fig. 2, in part transverse section.
The drum, a, is mounted on its axis, b, which latter passes through and works
in bearings formed in the casing, c. The drum, a, is provided with lateral openings
of such a width as to receive its piston, d, which latter is advantageously of tubular
form, to allow of packing, with the advantage of lightness. The openings in the
drum, a, are extended towards the centre, a sufficient distance, to allow of the
pistons being contained therein in the manner shown at Fig. 1. These openings in.
the drum are provided with guide faces, a¹, between which the pistons, d, rotate,
and are thereby guided during the length of their stroke with the rotation of the
carrier, a. The guides are extended inwards such a distance that, in whatever
position or point of stroke the pistons may assume, contact is maintained against
the guide face, yet the aforesaid openings are open to the centre, to allow of an
interposing ring, e, on either side the central web, whereby the pistons, d, are
caused to roll on the inner surface of the cylinder, or casing, c, and parallel in all
positions to the axis, b, of the carrier, a. The rings, e, when three or more pistons
are employed, will always remain concentric to the cylinder, yet will rotate with
the pistons around its centre.
In Fig. 1, f, is the inlet, and g is the outlet, so that during rotation of the
carrying drum, a, and pistons in the direction shown, the pistons, d, d, d, will turn
with the rings, e, e, in the directions indicated by the arrows.
Where two pistons only are used, or it may even be in other cases), it would be
necessary to mount the distance ring or rings, on a stud secured to the one side
of the casing, whilst the drum spindle would be connected at the side thereof, and
work through the opposite side of the cylinders to that on which the distance
roller is mounted.
It will be seen that, by the aforesaid rings or roller, the apparatus can be driven
and will work at the slowest speed without depending on centrifugal force and high
velocity to cause the pistons to bear on the inner periphery of the cylinder, at the
same time having to resist the pressure of the fluid that may be passing through
the apparatus.
I am aware that in Beale's Specification, N° 9027, A.D. 1841, roller pistons
operating centrifugally were shown and described, but to no part of these do I lay
any claim.

page_text: 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
In rotary apparatus, whether as a meter, blower, exhauster, pump, or motor,
where rolling pistons are employed, the application of an interposing roller, ring, or
rings, free to rotate, for the purpose of mechanically causing the aforesaid pistons
to run on the inner periphery of the cylinder as herein described and shown.
