I, GEORGE HASELTINE, of the "International Patent Office," No. 12, South-
ampton Buildings, Chancery Lane, in the County of Middlesex, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN LEVER HORSE-
POWER MACHINES, THE COG GEARING EMPLOYED BEING APPLICABLE TO OTHER
MACHINES," a communication from Cyrus Avery, of Philadelphia, State of
Pennsylvania, United States of America, to be as follows:-
The nature of the said Invention consists in a novel construction of the
master wheel, and its arrangement in connection with the intermediate gear
wheels; in rotating the main shaft with only the stepping for its bearing; in
supporting the driver's seat on a standard that may be attached to or detached
from the main shaft at the pleasure of the driver; to so constructing the
machine that the dust and other foreign substances are excluded without the
use of a casing; and in connecting the band wheel shaft with the tumbling
shaft in such a manner that both rotate in one direction at unequal rates of
speed. The frame and other parts of this machine are constructed of any
suitable material and convenient form. The master wheel contains upon its
inner circumference two or more converge gears of different diameters forming
a kind of cone. Each of the gears drives a different set of intermediate
wheels, through which motion is imparted to the main shaft. These inter-

page_text: mediate wheels are connected to the pinion on the main shaft by couplings,
which may be in part or all removed, and the power applied to the central
pinion direct from the master wheel, whereby the power and velocity of the
machine may be varied as required to adapt the machine to different purposes.
These intermediate wheels are supported by bed plates, the lower one resting
on the frame of the machine. Below this plate is located the stepping on
which the main shaft revolves. The main shaft is constructed hollow, and the
lower end fits loosely on a hub that projects up from the stepping. The
driver's seat is supported by a rod or standard that passes down inside the main
shaft, and rests on the hub projecting up from the stepping. The main shaft
revolves around this standard, but it may be connected with it by any suitable
device, so that the driver may conveniently connect or detach the two as may
be desired. There is a cover situated below the driver's seat for excluding
the dust which may be used to connect the master wheel to the pinion on
the main shaft, and a plate at the bottom which is also employed as a support
for the stepping. Dust and other substances are excluded from the sides
partly by the frame and partly by the flange of the master wheel. On the
bottom of the shaft is fixed a gear wheel, through which motion is conveyed to
the tumbling rod in the ordinary manner. The second section of this rod
connects with a short shaft, which is fixed firmly to a plate within the jack.
This jack has two long journals which form the bearings of this shaft and the
shaft of the band wheel. The shaft of the latter has a pointed end which
runs into the short shaft. This jack contains on its inner circumference cog
gearing. In the plate to which the said short rod is secured, and near to its
periphery, axles are fixed, which bear intermediate cog gear wheels, the same
acting upon a pinion of the same circumference fixed on the shaft of the band
wheel, thereby acelerating the motion of the latter to the desired extent.
