Portable Water Motor.
I, JOHN BOLGIANO, Jr. of the City of Baltimore, and State of Maryland,
United States of America, Gentleman, do hereby declare the nature of my
invention for PORTABLE WATER MOTOR, and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
My invention relates to a portable water motor for running any kind of light
machines, such as sewing machines, fans, and the like. The object is to provide a
simple and cheap motor of the vertical wheel type.
In the accompanying drawing:
Figure 1, is a vertical section of my improved device and showing the same in
position in a stationary wash-basin and connected with the basin cock.
Figure 2, is a cross section of the wheel and its case on the line 2-2 of
Figure 1.
The wheel consists of a thin central disc, A, of sheet metal having peripheral
tangs, b, each of which has a quarter turn or twist so as to bring the broad face of
the tang in a plane at right angles to the surface of the disk; a circular cup, c, is
seated on the broad face of each tang and secured by solder or in any suitable
way. At its center the disk is re-inforced by a small convex disk, d, one on each
side, this completes the wheel. A shaft, e, passes through the wheel and has
bearings in the two broad sides of the case, f; a pulley g, is mounted on the
projecting end of the shaft.
The case has a rounded top, h, and straight vertical sides, f, i, which extend down
far enough to form a spacious chamber, p, below the wheel;-at its lower end each
of the two narrow sides converges toward the other and forms a funnel, j¹, to which
the waste or discharge pipe, k, is attached; in the top of the case is an inlet
nozzle, l, which points directly down and is much smaller than the discharge-
pipe, k, and at each narrow side, a spring arm is attached and the free end of these
arms have an ogee curve or bend, t, to engage with the inner end of the slab, n, on
top of the wash-basin and thus support the case upright.
A piece of hose, o, connects the inlet, 1, with the cock, o'.
The lower end of the discharge pipe, k, enters the waste hole, g, of the wash
basin; thus the spring arms, m, and this pipe serve to support the motor upright
and hold it steady in the basin.
An ear, r, is attached at each side of the case.
In operation the current of water from the inlet nozzle, l, passes down and strikes
the cups, c, causing the wheel to revolve; both the force of the blow on the water
cups, caused by the pressure and the weight of the water, are utilized to their
fullest extent. As the central part of the wheel is a thin vertical disk, A, the
water is not held or retained on the wheel but quickly frees itself therefrom and
the wheel revolves with great rapidity; the water takes a downward tangent,
indicated by the broken line, s, and strikes the narrow side, i, of the case and is
then deflected therefrom at an angle indicated by the broken line, s', directly into
the discharge-pipe, k. The thin vertical disk of the wheel; the vertical inlet
nozzle entering the top of the case; the spacious chamber in the case below the
wheel, and the narrow vertical sides, i, converging to the discharge pipe,-all
combined to produce the desired result, to wit: high speed of revolution of the
wheel prompt clearance of the water, and consequent avoidance of back-lash.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
-claim is ;
1st. The herein described water motor having straight narrow sides, i, con-
verging at the bottom to a discharge pipe; a vertical wheel in the case having a
thin center disk provided with peripheral tangs, b, with a quarter turn or twist and
cups on the tangs; a vertical inlet nozzle entering the case top; and a spacious
chamber, p, in the case below the wheel, as shown and described.
2nd. A portable water motor having a vertical case, A, provided with a vertical
discharge pipe in the lower end; a vertical wheel in the case; and two spring
arms m, each attached to the case at a side opposite the other said arms having at
their free ends an ogee curve or bend, t, as and for the purpose set forth.
Dated this 21st day of April 1893.
JOHN BOLGIANO.
