Newark, in the County of Nottingham, and James Kennan, of the City of
Dublin, both Agricultural Implement Manufacturers, for the Invention of "IM-
PROVEMENTS IN HORSE GEARS OR HORSE POWERS."
ealed the 8th September 1877, and dated the 12th March 1877.
PROVISIONAL SPECIFICATION left by the said William Newzam Nicholson
and James Kennan at the Office of the Commissioners of Patents on the 12th
March 1877.
WILLIAM NEWZAM NICHOLSON, of the Trent Iron Works, Newark, in the County
of Nottingham, and JAMES KENNAN, of the City of Dublin, both Agricultural
Implement Manufacturers. "IMPROVEMENTS IN HORSE GEARS OR HORSE POWERS."
This Invention has for its object improvements in horse gears or horse powers.
We propose to construct the main part of these horse gears in the customary
manner. The horse shafts being connected with a vertical spindle carrying a main
cog wheel in the centre of the horse walk, from which the motion is transmitted
through bevil gearing by a tumbling shaft or connecting rod to an intermediate
motion outside the horse walk.
Our improvements consist in a new arrangement of intermediate motion. This
new intermediate motion consists of a suitable framing containing a pair of bevil
cog wheels. The spindle or shaft carrying the first of these bevel wheels is con-
nected with the tumbling shaft of the main part of the horse gear. The second
bevil wheel, which is driven by the first, is fixed on a vertical spindle, which spindle
passes through the top of the framing; and upon this same spindle is keyed a
pulley (or pullies) horizontally, from which pulley any such machines as may be
wished to drive being placed in radial positions round the intermediate motion are
driven by a half twisted belt running upon the vertical pulley fixed to each
machine.
In some cases we propose to use spur gear as well as bevel gear, so as to drive
from a vertical as well as from a horizontal pulley. To effect this we key a spur

page_text: wheel on the same shaft which carries the first bevel wheel. This spur wheel gears
into a pinion fixed on a shaft, which is prolonged so as to allow a vertical pulley
to be fixed upon it on the outside of the framing. From this pulley any machine
or countershaft placed in a suitable position can be driven.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Newzam Nicholson and James Kennan in the Great Seal
Patent Office on the 12th September 1877.

We propose to construct the main part of these horse gears in the customary

wished to drive being placed in radial positions round the intermediate motion are
driven by a half twisted belt running upon the vertical pulley fixed to each
machine.
In some cases we propose to use spur gear as well as bevil gear, so as to drive
from vertical as well as horizontal pullies. To effect this we key a spur wheel on
the same shaft which carries the first bevil wheel. This spur wheel gears into a
pinion fixed on a shaft, which is prolonged so as to allow vertical pullies to be fixed
upon it on the outside of the framing. From this pulley any machine or counter-
shaft placed in a suitable position may be driven.
In the accompanying Drawings,-
Fig. 1 represents a side elevation of our improved horse gear; and Fig. 2 is a plan
of the same.
The main part A is constructed in any of the ordinary methods, and
communicates motion through the tumbling shaft B to the bevil wheel C of the
"intermediato motion." This bevil wheel is in gear with a bevil pinion D keyed
on the vertical shaft E, thus giving motion to the horizontal pulley F, which is also
keyed on the same vertical shaft. From this pulley F a half twisted belt drives
any machines placed radially around it; thus in Figure 2 the machine X is shown
as being driven by the belt K, which belt can be used for driving the machine Y,
as shown in the dotted lines K*.
Fig. 3 represents a longitudinal vertical section of our improved "intermediate
motion," but having in addition to the bevil wheel C a spur wheel H, also keyed
on the same horizontal shaft. A second horizontal shaft L carries the sliding
pinion I for giving motion from the spur wheel H to the vertical pullies M and M*.
The bevil pinion D is also made to slide on its shaft E, so that either the horizontal
pulley For the vertical pullies M, M*, can be used at pleasure, or all may be used
at the same time.
Having now described the nature of our Invention and the manner of performing
the same, we would have it understood that what we claim and desire to protect is,

horse gears, as herein described.
In witness whereof, I, the said William Newzam Nicholson, have hereunto
set my hand and seal, this Eighth day of September, in the year of our
Lord One thousand eight hundred and seventy-seven.
