page_text: NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification under my hand and seal fully
describes and ascertains the nature of the said Invention, and in what manner
the same is to be performed, in and by the following statement, reference
being had to the accompanying Sheets of Drawings, in which Figure 1 is
a side elevation of the machine complete; Figure 2 is a plan of the machine
complete; Figure 3 is a longitudinal vertical section of the whole machine
through the centre; Figure 4 is a plan of the. machine, partly in section,
showing the two gears of the main wheel and corresponding sets of main
gears; Figüre 5 is a coupling designed to connect the lower centre pinion
with the main shaft; Figure 6 is a coupling design to connect the main wheel
to the main shaft by means of the cover..
The nature of my Invention consists in the peculiar construction and
arrangement of the gearing for lever horse powers and other purposes in
making the master wheel in a conical form, in running the main shaft
without any bearing except the stepping, in the manner of oiling, in securing
all the parts from dirt, in seating the driver so that he need not be carried
around by the motion of the team, in running one end of the band wheel
'shaft into the end of the tumbling shaft running the same way but with
greater velocity, and in producing the slowest and the highest velocity.
DESCRIPTION OF THE MACHINE.
For a medium sized machine, the frame A upon which the bed plate
rests is constructed of scantling or timber with side pieces from ten to
twelve feet by four and six inches framed together by four cross pieces
about thirty-seven inches long, the two end pieces being about six inches
from each end of the side pieces, and made of timber four by six inches.
The middle cross pieces are made of plank four by twelve inches with
a double tenon on each end projecting through the side pieces one inch
and framed into the sides forming a square of thirty-five inches and about
two feet nearer one end of the frame than the other.
On the top of
the side pieces are two more pieces, one on each side, forty-seven inches
long, four by six inches, framed to the centre cross pieces. Two-braces,
three by four inches, crossing each other, are keyed in tight, at the long
end of the frame. A groove is cut in the centre cross pieces facing each
other two inches up from the bottom, one and a half inches wide and
half an inch deep. A plank one and a half inches thick is fitted into
these grooves, forming a bed for the step of the main.shaft and for keeping
out dirt.

B is the bed plate made of cast iron, five-eighths of an inch

page_text: thick and thirty-five inches square, and bolted to the frame with four
bolts. Fitted to this plate are three studs or journals for the intermediate
wheels to revolve upon, with a recess or cup ȧround the same as a reser-:
voir for oil, with heavy stays on the under side running from one stud to.
the other, and from the studs into the frame. C is the main wheel of:
cast iron; the lower section is thirty inches across. at the pitch line and
with four inches width of periphery with fifty-one teeth; .the second section is.
twenty-eight inches across on the pitch line, and has sixty teeth with three:
and a half inches width of periphery. On the outside of this wheel horns are;
cast in such a way as to form recesses for the ends of the sweeps, as
shown in the Drawings. On the lower edge is a flange projecting out one:
and a half inches, and one inch thick. D is the cover, cast about one and a.
half inches crowning, with a hole through the centre for the staff of the driver's:
seat to pass through, with two horns projecting out one opposite the other, with
a-hook projecting down to hook it on the main wheel in such a way that if the.
gearing rub against the cover it will not unhook it. On the top of these..
horns are handles in the shape of an arch, and on the inside is a square,
flange projecting down one and a half inches to connect the cover with;
the main shaft when the centre pinion is removed. E is the driver's seat,
made of iron or wood, or both, sixteen or eighteen inches high, having a
standard under the seat with a hole through the lower end to fit on the.
staff loosely, with a foot piece projecting out over the cover. When the :
driver places his feet on this foot piece he will not revolve with the
machine. The staff is about forty inches long, of iron or wood, the lower:
-end passing through the cover and through the main shaft, loosely fitted.
into the centre of the stepping, the upper end into the socket of the:
driver's seat. F, F, F, are the upper intermediate wheels, eleven inches.in.:
diameter, with twenty-four teeth, three inches periphery, revolving on, the
studs or journals in the plate H. G is the top centre: pinion; about five..
and three-fourths inches in diameter, and three and one-quarter: inches,
periphery. On the under side is a flange connecting the teeth together,...
the hole through the centre of this pinion is three and. three-quarters;
inches in diameter, with two half round feathers projecting in to connect
with the main shaft. H is a triangular plate, three-fourths of an inch..
thick, with a pinion about nine inches in diameter, and five, inches width:
of periphery, four and a half inches in length of teeth, number of teeth:
fifteen. It has a hole in the centre six and a half inches in diameter,.
with three recesses five-eighths of an inch deep to. connect with coupling..

page_text: to the main shaft. Near each corner of the triangular plate H are three
hubs with cups passing around the studs O about four inches in diameter
and one and a half inches thick. I, I, I, are the lower intermediate wheels,
ten and three-fourths inches in diameter, four inches width of periphery,
and eighteen teeth. J is the first piece of the tumbling rod; on one end
is fitted a bevel pinion about five and a half inches in diameter to gear
into the bevel wheel. On the other end is fitted a hollow socket to con-
nect with the second section of the tumbling rod; this rod has two journals
about five inches long. K is the main shaft and bevel wheel; the wheel
is twenty-six inches in diameter, with sixty-one teeth, with a flange con-
necting the teeth together on the outside forming a dish to hold oil: The
shaft is four and a half inches in diameter, with two half round grooves
at the top end about eight inches long, to connect the gearing to the main
shaft, with a hole about three inches in diameter through the whole length
of said shaft. L is the bevel pinion, three and a half inches periphery,
with twelve teeth. M is the second section of the tumbling rod, about
nine feet long; on one end is fitted a square hub to fit into the hollow
socket loosely. N is the stepping, about six inches in diameter, in the form
of a dish. A hub projects up two inches, being two inches and a half
in diameter, and fitting loosely into the main shaft.. The lower end of the
staff of the driver's seat fits loosely into the centre of this hub. 0, 0, 0,
are the studs that the upper intermediate wheels revolve on, one and a half
inches in diameter and about five inches long. P, P, P, are studs or journals
about one and three-fourths inches in diameter and about seven inches
long. The lower intermediate wheels revolve on these studs. The studs O
and P have grooves cut in them to admit wick and oil. Q, Q, are buttons
slipping easily on the bolts that hold the bed plate B down. The object
of these buttons is to hold the main wheel down. R is the hollow coupling,
about four inches in length and three inches square inside. S is the top
part of the shell of the jack, about fourteen and a half inches in diameter
and three-eighths of an inch thick, with hubs projecting out six inches to form
boxes for the shafts. Inside of the top part S are twenty-seven teeth. T
is the bottom part of the jack, of the same dimensions as the top, with
suitable fastenings to hold it in position. U is the band wheel or cylinder
shaft. V, V, are the intermediate wheels, four inches and a half in diameter
and two inches width of face. W is the revolving plate, one and a quarter
inches thick through the hubs. X is the centre pinion, having the same
dimensions as the intermediate wheels. Y, Y, are studs one inch in diameter

page_text: and four inches in length. Z is a shaft about one foot in length that connects
with the tumbling rod at one end, and at the other is fitted tightly to the plate
that holds the studs Y, Y.
Having thus fully described my said improvements, I wish it understood
that I do not confine myself to the exact details herein set forth, or to the
material used in the construction of the frame and other parts, as any suitable
material may be used without departing from the spirit of my Invention, but
I claim,-
First, constructing the main wheel C with two or more sets of teeth gearing
into the intermediate wheels I and F, the main wheel moving to the left,
while the upper series of intermediate wheels F move to the right and vice
versa.
Second, using the the main shaft K without any bearing except the
stepping.
Third, constructing the seat E so that the driver can remain stationary or
revolve at pleasure.
Fourth, the construction, combination, and operation of the parts S, T, V,
W, X, Y, Z, forming the jack in connection with the band wheel or cylinder
shaft U.
Fifth, in so constructing and arranging the parts of the machine that dirt is
excluded from the interior without the expense of boxing.
In witness whereof, I, the said George Haseltine, have hereunto set my
hand and seal, this Second day of July, in the year of our Lord
One thousand eight hundred and sixty-three.
GEORGE HASELTINE. (L.B.)
