Improvements in Horse Gears.
We, ROBERT ASHTON LISTER, of the Victoria Iron Works, Dursley, in the
County of Gloucester, Engineer, and MIKAEL PEDERSEN, also of Dursley, in
the County of Gloucester aforesaid, Foreman Engineer, do hereby declare the.
nature of this invention to be as follows:-
Our invention relates to an improved horse gear which is provided with three
sets of gearing, namely, two sets of spur gear and one set of bevel gear, whereby
we obtain a high speed without a separate intermediate motion.
The draught poles are attached to the first motion, which is an internally geared'
ring, driving three spur pinions, each cast in one piece with the spur wheel of the
second motion placed underneath; these three spur wheels severally gear into one
spur pinion in the centre which is also cast in one piece with the bevel wheel placed
below driving the lay shaft by means of a bevel pinion.
A specially shaped base plate which is easily bolted to sleepers carries the lower
ends of the four vertical shafts whilst the upper ends of these are braced together.
and held in position by a suitable cover which also encloses the gearing.

COMPLETE SPECIFICATION.
Improvements in Horse Gears.
We, ROBERT ASHTON LISTER, of the Victoria Iron Works, Dursley, in the
County of Gloucester, Engineer, and MIKAEL PEDERSEN, also of Dursley, in
the County of Gloucester aforesaid, Engineer, do hereby declare the nature of this
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
-:
This invention relates to an improved horse-gear, and has for its object to obtain
a high speed of rotation without using a separate intermediate motion as heretofore.
According to our invention the horse-gear is provided with two sets of spur-.
gearing, and one set of bevel-gearing. The first motion set of gearing comprises
three spur pinions engaging with an internally geared ring to which the draught or
driving poles are connected whilst the second motion set of gearing comprises three
spur-wheels formed integral with, or mounted upon the same shafts as the pinions
hereinbefore referred to and engaging with a common pinion. This pinion is connected
with a bevel-wheel engaging with a bevel-pinion mounted upon the shaft to be
driven and which is commonly known as the "lay-shaft."
To enable our invention to be fully understood we will describe the same with
reference to the accompanying drawing, in which :-
Figure 1 is an elevation partly in section on the line ax Figure 2, of a horse-gear
constructed according to our invention; and,
Figure 2 is a plan of the same, certain parts being removed.
In carrying out our invention we provide a base plate or bed a which is provided
with lugs b, b for enabling it to be secured to sleepers c, c or some other suitable
foundation. To the said base plate are secured three vertical shafts d, d, d, each of
which carries a toothed pinion e forming part of the first motion set of gearing, and
a toothed wheelf forming part of the second motion set of gearing, the wheel and
pinion upon each shaft being connected preferably by forming them in one piece.

page_text: Engaging with the pinions e, e, e and driving the same is an internally geared
ring upon which sockets for carrying the draught poles may be formed. Above
the ring and covering the centre of the same is a cover h which is mounted upon
the upper ends of the shafts d, d, d being supported thereon by means of shoulders,
the said cover serving not only to protect the gearing, but also to hold the
shafts d, d, d steady; anti-friction rollers may be arranged between the geared ring
and the cover.
At the centre of the cover his secured a downwardly projecting shaft i upon
which is carried a pinion k forming part of the second motion set of gearing and in
engagement with all the wheels f, f. Secured to or formed integral with the
pinion is a bevel-wheel forming part of the set of bevel-gearing and engaging
with a pinion m upon the lay-shaft n.
With the construction herein before described it will be obvious that, when motion
is communicated to the ring g, this motion will be transmitted to the pinions e, e, e
which will make several rotations to each rotation of the said ring; from the
pinions e the motion is transmitted through the wheels f,ff to the pinion which
will, owing to the relative diameters of the said wheels and pinions, make several
rotations to each rotation of the wheels f, f, f; from the pinion & motion is com-
municated through the bevel-wheel to the bevel-pinion m upon the lay-shaft n and
thence to any desired point. It will thus be understood that a relatively slow
motion of the ring g will cause a very rapid rotation of the lay shaft.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a horse-gear, the combination of three sets of gearing, namely, a set of
spur-gearing comprising an internally toothed ring engaging with a series of pinions,
a second set of gearing comprising a series of gear-wheels connected to or formed
integral with the pinions of the first mentioned set of gearing, and all engaging with
a common pinion connected with a set of bevel-gearing, through the medium of
which the motion of the pinion of the second set of gearing is communicated to the
lay-shaft, substantially as described.
2. The manufacture and use of the improved horse-gear herein before described
and illustrated in the accompanying drawing.
