the Office of the Commissioners of Patents, with his Petition, on the
30th May 1863.
I, EDWARD PAYSON MOSMAN, of Springfield, Massachusetts, in the United
States of America, now residing at Enfield Highway, in the County of
Middlesex, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN OBTAINING AND APPLYING MOTIVE POWER," be as follows:-
My Invention consists in changing circular into rectilinear motion, and vice
versa, so that centripetal force brings into action centrifugal force, or vice
versa, and by the system of complex and duplex mechanical arrangements
herein-after 'described the original power is maintained, thus producing motive
power for practical use. I have a frame for supporting the wheels and other
mechanism hereafter described. This frame supports a horizontal shaft which
carries a tooth wheel, a fly wheel, and a bevil wheel. The bevil wheel is
situate on one end of the shaft, and gears with a second bevil wheel cor-
respondingly toothed, set on its own axis or shaft, and placed at right angles
to the axle or shaft first mentioned. The shaft of the second mentioned, bevil
wheel has quarter toothed cam wheels on either end, which take into
corresponding teeth of weighted racks, so as to raise the same alternately, in
order that they may fall, and thus obtain the use of centrifugal force or
attraction of gravitation as falling weights, which rectilinear or upward and
downward motion is accomplished by circular or rotary motion being given to

page_text: the fly wheel before mentioned. The weighted racks aforesaid are toothed on
opposite sides in order that the sides not heretofor described shall take into
similar cam wheels to those already described, which last-mentioned cam
wheels are on an axle or shaft having a bevil wheel similar to those before
described, which gears with a correspondingly toothed wheel situate at right
angles set on a shaft which carries a fly wheel and toothed wheel similar-to
those herein described, and in the same plane. The weighted racks overhang
and fall upon secondary racks toothed upon the faces thereof, which take into
wheels correspondingly toothed, situate on a shaft between them; consequently
a downward motion being given to the secondary rack on the left upward
motion is conveyed to the secondary rack on the right, which on receiving the
impetus of the falling weight or weighted rack immediately descends and a
corresponding action takes place to that already described. The secondary
rack being a frame with teeth on its face and inner sides, the inner teeth
placed on opposite sides but not in the same line, so that they may take into
two toothed wheels one behind the other, and loose on a shaft set at right
angles to the rack and within the same. Upon upward and downward
or rectilinear motion being given to the rack the wheels will move in opposite
directions. The shaft has ratchet wheels fixed thereto, one on either side of
the loose wheels or pulleys, which have pins or palls on their faces, which take
into the ratchet wheels, consequently rectilinear motion being given to the rack
the shaft is driven constantly in the same direction. The axle or shaft has a
wheel gearing with multiplying wheels, whereby a multiplied action is given
to a fly wheel to facilitate the accumulation of centrifugal force. A worm is
placed on the shaft, situate between the fly wheel and the multiplying wheels,
which gears with worm wheels attached to shafts placed above and below, and
at right angles to the wormed shaft aforesaid, these shafts carrying toothed
wheels at each end, gearing into other wheels, which being connected with the
toothed wheel first mentioned, turn it and the fly and bevel wheels constantly
in the same direction. The above arrangements are twice repeated. The lower
end of the weighted racks are provided with adjusting screws which drop upon
a cushion at the end of an upright or pin, passing through and projecting on
either side of a pendulum lever, which upright is enveloped in a coiled spring
on either side of the pendulum, which latter is secured at one end to standards,
and has an adjustable weight to assist in regulating the power, which power
is
increased or diminished by the concussion obtained on the meeting of the
weighted racks in their downward movements with the upward movements of
the pendulum. The oscillation of the pendulum is maintained in a semi-
circle by means of a toothed wheel gearing with the wheel which unites the

page_text: secondary racks, as herein-before described; such toothed wheel also gearing
with a wheel set on the upper part of the pendulum, of which it forms a part.
The above arrangements may admit of the various parts being superseded
by equivalents.
