I, JAMES WILSON MARTIN, of 9, James Street, in the City of Liverpool,
Engineer and Machinery Merchant, do hereby declare the nature of this inven-
tion to be as follows:-
The object of my invention is to form a rotary motor actuated by weights
without the assistance of any outside agency. For this purpose I have a wheel
-which I call the motor wheel--mounted on a shaft which turns in suitable
bearings fixed to a bedplate. This motor wheel has two or more spokes radiating
from the central boss to the rim of the wheel; and on each of these spokes I
have one or more weights sliding freely up and down thereon as the wheel
revolves, by having a roller or other appliance attached to each weight travelling
in a circular or other shaped guide placed alongside and eccentrical with the
motor wheel; this guide being for the purpose of automatically altering the
positions of the weights on the spokes, and those on or under the rim described
below.
I attach this guide in a suitable manner to a movable slide on the bedplate,
so arranged that it can be placed eccentrically on either side of the wheel shaft
for running the motor wheel in either direction, or central with the shaft for
stopping the wheel. The weight on each spoke is connected, by means of a
rope passing over one or more pulleys attached to the wheel, to another weight
sliding freely backwards and forwards on the rim, or in suitable pockets under
the rim of the motor wheel between each spoke. The object of these rim
weights is to balance and assist the action of the weights on the spokes; and
in some cases, in order to shorten the travel of the rim weights, I prefer to
have. these heavier than those on the spokes; and to connect the two weights
in each series by proportionate and suitable multiplying gear.
The action of the whole is such, that when the motor wheel is in action, the
positions of the weights on the spokes and rim is so arranged that there is always
a heavy and a light side to the wheel; which, being thus continually out of
balance, is impelled round continuously by reason of the gravity of the weight
or weights on the heavy side, acting at a greater distance from the centre than
those on the lighter side which are nearer to the centre.
In some cases I dispense with the circular guide to move the weights, and
connect each weight by a rod or other suitable connection to a bearing or axle
eccentric with the centre of the wheel.

I, JAMES WILSON MARTIN, of 9, James Street, Liverpool, in the County of
Lancaster, Engineer and Machinery Merchant, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:
-
This invention has for its object to form a rotary motor actuated by weights,
without the assistance of any outside agency.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which,
Fig. 1 is a side elevation,
Fig. 2 a side view with one of the guides H, standard C, and eccentrics ()
removed,
Fig. 3 an end view partly in section.
Referring to these figures, A. is a wheel which I call the motor wheel mounted
on a shaft B which rotates in suitable bearings on the standards C fixed to a
bed plate D. This motor wheel has spokes E radiating from a central boss to
the rim of the wheel, and on each of these spokes I have one or more weights F
sliding freely up and down thereon as the wheel revolves. This radial sliding
of the weights is effected by having rollers G on the weights which travel in a
circular guide H placed alongside, but eccentric with the motor wheel. This
guide H is designed to automatically alter the positions of the weights Fon
the spokes E as the wheel rotates, and also the counter weights I hereafter
describe. The guide H is attached in a suitable manner to a movable slide J
on the bed-plate D so that it can be placed eccentrically on either side of the
wheel shaft B for running the motor wheel in either direction, or central with
the shaft for stopping the wheel. The weight F on each spoke is connected
by means of a rope or line K passing over one or more guide pulleys L fitted
to the wheel, to the counterweights I. These slide freely backwards and for-
wards circumferentially on the rim or guide M of the wheel between each
spoke. The object of these rim weights I is to counterbalance the weights on
the spokes as otherwise the power required to move the weights F would be
very great, whereas by counter weighting them they can easily be moved back-
wards and forwards along the spokes. A further object in some cases is to
shorten the travel of the weights 1. I prefer to have the weights I heavier
than those on the spokes, and to connect the weights in each of the two series
by proportionate and suitable multiplying gear hereinafter described.
The action of the whole is such that when the motor wheel is in action, the
positions of the weights F on the spokes E and the rim M is so arranged that
there is always a heavy and a light side of the wheel, which being thus con-
tinually out of balance is impelled round continuously by reason of the gravity
of the weight or weights on the heavy side acting at a greater distance from
the centre than those on the lighter side which are nearer to the centre. The
proportionate and suitable multiplying gear is so arranged that the weights I
are adjustable nearer to or further from the centre B by mounting the weights I
in the slide which travels circumferentially on the guide M. In such case
the weights I are coupled to the axle B by an eccentric O and rods N, the
eccentric being loose on the shaft and held from revolving by the toothed rack
and pinion hereinafter referred to. Thus during the rotation of wheel, the
eccentric strap T revolving round the stationary eccentric will work the weights I
to and fro radially, and the said weights will have two motions, namely, a radial
one and a circumferential one. P is a toothed rack on the guide H into which

page_text: a pinion S on the shaft B gears. This pinion is loose on the shaft, but is
secured to the eccentric O. To reverse the motion of the wheel, screw Q is
turned by handle R, this operates the slide J and rack P which turns the
pinion S. If the latter therefore be connected with eccentric O and the
handle R be turned, the eccentric will be rotated, and the positions of the
respective weights reversed, to make the wheel revolve the opposite way. If
desired the counterweights I may be arranged so as not to be adjustable nearer
to or further from the centre, and an auxiliary set of weights forming another
set of driving weights, may be provided mounted on the rim of wheel worked by
the eccentric and rods aforesaid.
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. A motor consisting of a rotary wheel actuated by sliding weights mounted
on spokes or guides and so arranged that there is always a heavy and a light
side to the wheel, which being thus continually out of balance is impelled round
continuously by reason of the gravity of the weight or weights on the heavy
side, acting at a greater distance from the centre than those on the lighter side
which are nearer to the centre, substantially as described.
2. A motor wheel in which weights sliding on radial arms or guides are caused
to alternately approach and recede from the centre of rotation, in such a manner
that the weights in descending during rotation shall be at a greater mean distance
from the centre of rotation, than when on the ascending side, substantially as
and for the purposes described.
3. In a motor comprising a wheel having weights which are adapted to slide
on spokes or guides, the arrangement of a circular guide H placed alongside
the motor wheel but eccentric therewith, in which rollers or blocks on pins pro-
jecting from the weights are adapted to slide, whereby the said guide being
eccentric will automatically alter the positions of the weights as the wheel rotates,
substantially as and for the purposes described.
4. In a motor of that kind in which motor power is obtained by varying the
positions of weights on the spokes or arms so that there is always a heavy and
a light side of the wheel, mounting on circumferential guides or ares, counter
weights adapted to slide freely backwards and forwards between each spoke,
and connected with the main weights in such manner as to counterbalance them
while at the same time ensuring that there shall always be a heavy and a light
side to the wheel substantially as described.
5. In a motor of the kind described in Claim 4, arranging the counterweights
on the circumferential guides or arcs so as to slide radially as well as backwards
and forwards in an arc, in combination with a stationary eccentric on the shaft,
an eccentric strap fitted thereon and rods coupling said strap to the weights.
whereby during the rotation of the wheel the eccentric strap revolving round
the stationary eccentric will effect the necessary movement of the weights in
the radial direction, substantially as described.
6. The arrangement for reversing the motor wheel herein set forth, or for
stopping or varying or regulating the speed of same, which consists in mounting
the guide which varies the position of the weights on a movable slide on the
bed-plate of the machine so that it can be placed eccentrically on either side
of the wheel shaft or central with the shaft substantially as described.
7. A motor substantially as described and illustrated in the accompanying
drawings.
