IMPROVEMENTS IN HORSE GEARS
Year: 1884

page_text: I, ROBERT BURNS Mechanical Engineer of Rugeley in the County of Stafford
do hereby declare the nature of my invention for IMPROVEMENTS IN HORSE
GEARS to be as follows:-
:-
This Invention has for its object Improvements in Horse Gears whereby such
Machines are rendered less liable to breakage, and more effective in work.
The First part of this Invention relates to the upright or main shaft E Fig 3
and consists in fixing thereon a centre piece or Pawl Box, P as shown on
Fig 3 & 4.
The Second part relates to the driving wheel D and consists in fixing or forming
upon its centre part a suitable internal ratchet wheel N Fig 3 & 4.
The Third part relates to the aforesaid Pawl Box P and consists in fitting to
the same one or more Pawls P1 and P2 Fig 4 (or catches) that shall take into
and act automatically on the Ratchet Wheel N and thereby firmly engage the
upright or main shaft E with the driving wheel D.
The fourth part relates to the use of a Fly Wheel H 1 (on the pinion shaft H) in
combination with the above shewn in drawings.
It will be readily understood from the Plan view Fig 4 that if the shaft E and
pawl box P be turned in the direction of the Arrows, the pawls P1 & P2 will
engage with the ratchet wheel N and communicate motion to the driving wheel D
through the pinion K to the flywheel shaft H and the coupling rod S.
The Fifth part of this invention relates to Fig" 1 & 2. where the order of the
preceding arrangement is inverted (ie) the ratchet wheel G (substituted for
the ratchet wheel N) is fixed on the top part of the upright spindle E, and the
pawls P 1. P2 attached to the pole box F. Fig 2. (F being made to run loose on
the neck of the shaft E) D1 the centre piece keyed firmly on the upright shaft E,
and bolted securely to the driving wheel D, K Fig 1 is the pinion, which takes
into & receives motion from the driving wheel D. H pinion shaft which has its
bearing on the sole plate A. H1 the flywheel, the boss of which has formed upon
it two lugs, forming a jaw to receive the joint ball R, connecting the coupling rod S.
It will be seen from the plan view Fig 2. that if the Pole box F be moved in the
direction of the Arrows, the pawls will engage with the ratchet wheel G (and vice
versa) and communicate motion to the driving wheel D, through the shaft E and
thence to the pinion shaft & flywheel,

page_text: I, ROBERT BURNS, Mechanical Engineer of Rugeley in the County of Stafford
do hereby declare the nature of my invention for IMPROVEMENTS IN HORSE
GEARS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This Invention has for its object: improvements in Horse Gears whereby such
Machines are rendered less liable to breakage and more effective in work.
The first part of this Invention relates to the upright or main shaft E,
Fig 3 & consists in fixing thereon a centre piece or Pawl Box P as shewn on
Fig 3 & 4.
The second part relates to the driving wheel D and consists in fixing or forming
upon its centre part a suitable internal ratchet wheel N Fig 3 & 4.
The Third part relates to the aforesaid Pawl Box P and consists in fitting to the
same one or more Pawls P 1. P 2 Fig 4 (or catches) that shall take into and act
automatically on the ratchet wheel N and thereby firmly engage the upright or
main shaft E with the driving wheel D.
The fourth part relates to the use of a Flywheel H1 (on the pinion shaft H) in
combination with the above, shewn in drawings Fig 1. 2. 3 & 4.
It will be readily understood from the Plan view Fig 4, that if the shaft E &
pawl box P, be turned in the direction of the arrows, the pawls P1, P2, will
engage with the ratchet wheel N and communicate motion to the driving wheel D,
thence through the pinion K. to the flywheel shaft H and the coupling rod S.
The Fifth part of this invention relates to Fig 1. & 2, where the order of the
preceding arrangement is inverted (ie) the ratchet wheel G (substituted for
the ratchet wheel N) is fixed on the top part of the upright spindle E and the
pawls P 1. P 2. attached to the pole box F Fig 2, (F being made to run loose ou
the neck of the shaft E) D 1. the centre piece keyed firmly on the upright shaft E
and bolted securely to the driving wheel D. K Fig 1 is the pinion, which takes
into and receives motion from the driving wheel D. H pinion shaft which has its
bearing on the sole plate A H 1. the flywheel, the boss of which has formed upon
it two lugs, forming a jaw to receive the joint ball R, connecting the coupling rod S.
It will be seen from the plan views Fig 2 & 4 that if the Pole box F be moved in,
the direction of the arrows, the pawls will engage with the ratchet wheel G (and
vice versa) and communicate motion to the driving wheel D through the shaft E
and thence to the pinion shaft and flywheel.

Having now particularly described the nature of my said Invention and in
what manner the same is to be performed, I declare that what I claim is
1. Internal Ratchet Wheel & pawl box in combination with upright shaft (E)
and Driving wheel (D) substantially as shewn in drawings Fig 3 & 4.
a
2. External Ratchet Wheel (G) in combination with upright shaft (E) and pole
box (F) with pawls (P 1. P 2.) attached, substantially as shewn in drawings
Fig 1 & 2.
'
3. Forming the Main or Driving Wheel in two parts, substantially as shewn in
drawings Fig 1. 2. 3 & 4.
4. Fixing on the Pinion shaft (H) a flywheel (H 1) substantially as shewn in
drawings Fig 1. 2. 3 & 4.
Dated this 4th day of March 1885.
