I WILLIAM HENRY SLEEP, of St. Germans, in the county of Cornwall,
Implement Manufacturer do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in shafts and poles for carriages, carts,
tram-cars, agricultural implements, mowing and reaping machines and other
machinery in which shafts or poles are used and arms for chaff cutters, thrashing
machines, horse gears, and the like, the object of the invention being to reduce the
weight and increase the strength and rigidity of the said shafts poles and arms.
For this purpose I form the shafts poles and arms of channelled or U or
U section steel or iron or of O section that is to say having the edges of the
channel turned in so as to meet or nearly meet the channel being tapered from one
end to the other or from the centre to the ends or otherwise. The front part can
be curved from the point to any required distance backwards thereby bringing the
edges of the channel to meet and forming a tube. When used for dog carts gigs
or traps the shafts can be advantageously tapered from about the centre to the
ends thus obtaining the greatest strength where the greatest strain takes place.
The shafts poles or arms can be used with the edges of the channel downwards
and the round or arched part upwards and can be lined with wood if required.

I, WILLIAM HENRY SLEEP, of St Germans, in the county of Cornwall,
Implement Manufacturer, 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 improvements in shafts, and poles for carriages, carts,
tram-cars, agricultural implements, mowing and reaping machines and other
machinery in which shafts or poles are used, arms for chaff-cutters, thrashing
machines, horse gears, and the like, and handles for sack-carts, hand-carts, hand-
drills and the like; the object of the invention being to reduce the weight and
increase the strength and rigidity of the said shafts, poles, arms, and handles..
For this purpose I form the shafts, poles, arms and handles of channelled or U or
U section steel or iron, or of 0 section, that is to say, having the edges of the
channel turned in so as to meet or nearly meet, the channel being tapered from
one end to the other or from the centre to the ends or otherwise. The front part
can be curved from the point to any required distance backwards and the edges
of the channel be brought to meet and form a tube. When used for dog-carts,
gigs or traps, the shafts can be advantageously tapered from about the centre to
the ends, thus obtaining the greatest strength where the greatest strain takes
place. The shafts, poles or arms and handles can be used with the edges of the
channel downwards and the round or arched part upwards or vice versa, and can
be lined with wood if required.
In the accompanying drawing figure 1 represents a longitudinal elevation of a
shaft constructed according to my invention and suitable for ordinary carts and
implements of all kinds requiring shafts; figure 2 is a plan of the underside of the
same; figures 3 and 4 are cross sections on lines A B and CD respectively of
figure 1. The shaft is tapered from one end to the other and suitably curved as
shewn; the back part a, is made of steel or iron of channel shape in cross section
as shewn in figure 3, (or of the shape shewn in figure 3) whilst the part marked
from 6 to c, in figures 1 and 2, is formed with the edges of the channel turned
inwards in the manner shewn in figure 4, the front of the shaft from c, to the
extremity d, being formed tubular as shewn in figure 2.
Figure 5 is a longitudinal elevation of a pole or arm suitable for tram-cars,
mowing and reaping and thrashing machines, horse gears and the like and coaches
and carriages of all descriptions requising poles; figure 6 is a plan of the underside
of the same; the pole is constructed of similar section to the shaft herein before
described and shewn in figures 1 to 4, and is formed at its forward or small end
with a loop or ring (or a crook) for allowing the horses to be attached thereto.
If my improved pole or arm be required for use with horse gear, thrashing
machines or the like I attach the same by suitable means flatwise, that is to say,
in a position of which figure 5 represents a plan, the rounded or semi-circular part
of the channel being placed outwards or towards the horse.

page_text: Figures 7 and 8 are similar views to figures 1 and 2 but shewing my improved
shaft suitable for dog-carts, gigs, buggies and other similar light vehicles; figure 9
is a cross section on line E, F of figure 7, the deepest part of the shaft is at e, that
is to say, at about two thirds of its length from the front end the shaft being
tapered from the point e, towards each end as shewn in figure 7; the back end
of the shaft is somewhat flattened as shewn at f, in order to give a certain amount
of spring to the same, and it is formed with an eye or loop g, to allow of it being
easily attached to the vehicle; h, represents a flat piece of metal provided with
eyes or holes i, i, and adapted to cover in the open part of the channel, the said
piece h, being fixed by means of bolts or rivets j,j, passing through the sides of the
shaft and through the eyes or holes 2.
The spring f, hereinbefore described and shewn in figures 7 and 8 can if required
be dispensed with and the flat metal covering h, can be applied to all shafts, poles,
arms and handles constructed according to my invention or the channels thereof
can be filled in with wood or other suitable material as will be well understood.
I have not shewn in the drawings my improvements applied to the construction
of handles for sack-carts, hand-carts, hand-drills, and the like as their application
to such purposes will be sufficiently well understood from the foregoing description
without requiring illustration.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. Shafts, poles, arms for chaff-cutters, thrashing machines, horse gear and the
like, and handles for sack-carts, hand-carts, hand-drills and the like, formed of
channelled steel or iron of the sections shewn in figures 3, 3, and 4 of the accom-
panying drawing.
2. A shaft formed of tape channelled steel or iron, partly of the section
shewn in figure 3, or that shewn in figure 3ª, and partly of the section shewn in
figure 4 substantially as hereinbefore described and represented in figures 1, 2, 3, 3ª
and 4 of the accompanying drawing.
3. A pole formed of tapered channelled steel or iron partly of the section shewn
in figure 3, or that shewn in figure 38, and partly of the section shewn in figure 4,
substantially as hereinbefore described and represented in figures 3, 3º, 4, 5 and 6
of the accompanying drawing.
4. A shaft formed of tapered channelled steel or iron partly of the section shewn
in figure 3, or that shewn in figure 3ª, and partly of the section shewn in figure 4,
the open part of the channel being covered in by a netal plate h, (or filled in with
wood or other suitable material) substantially as herein before described and repre-
sented in figures 3, 3, 4, 7, 8 and 9, of the accompanying drawing.
5. The improved shafts and poles and arms for chaff-cutters, thrashing machines,
horse gear, and the like herein before described and represented in the accompany-
ing drawing and the herein described improved handles for sack-carts, hand-carts,
hand-drills and the like.
