Improvements in or connected with the Guides or Bearing Surfaces
for Sliding Links, specially applicable to the Connecting Rod Ends
of Mowing Machines.
WILLIAM DAUNCEY, of Hydegate, Uley, Dursley, in the County of Gloucester,
Machinist, 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:-
My invention relates to driving bar holders especially designed for mowing
machines but also applicable to other machines and is for providing a means
of relieving the catch spring of the driving bar holder of the strain upon it and
so preventing the driving bar from getting out of position and breaking in conse-
quence of the catch spring weakening and giving way; and so prevent the knife
which the driving bar works from being broken.
According to my invention I provide a casting to fit any shape shoe of the
mower. Fitted to this casting is another casting one side of which is covered
by a plate or steel. This aforesaid casting forming the guide. In the first or
main casting is fitted a latch to lock this aforesaid guide and in the first or main
casting is fitted a second latch, which locks the first latch. To enable my
invention to be fully understood I will describe same with reference to the
accompanying drawings in which ;-
Fig. 1 is a view in plan of my invention showing guide lifted to enable
driving bar to be lifted out.
Fig. 2 is a view in elevation showing the two latches for holding the guide.
Fig. 3 is a view in sectional plan A A showing catches holding guides.
Fig. 4 is a view in plan showing my invention fixed in position to the shoe
of an ordinary mowing machine.
Fig. 5 is a view in end elevation showing my invention fixed in position to
the shoe of an ordinary mowing machine.
A is the main casting made preferably of malleable iron and of any shape
to suit the main shoe of the mower.
B is the guide made preferably of malleable iron and on the side against
which the driving bar X travels to be covered with a steel plate C.
The aforesaid guide being hinged at D allows it to be turned round on D as
its centre and thus allows the driving bar to be removed. The joint pin D
is a fixture.
The aforesaid guide provided with snug E fits hole F, in the main casting A
and thus prevents any side play of the guide.
On the back of the main casting A is fitted a latch H made preferably of malle-
able iron which fits into a recess cast in the guide B at I. This aforesaid latch
goes through a hole cast in the main casting A at K.
The recess I in the guide B is cast in such a manner through the guide B
that the bottom side of the hole I always touches the bottom side of the latch H.
The recess K in the casting A is cast in such a manner that the top of the
recess K always touches the top side of the latch H.
"

page_text: The guide pressing against the latch H on the bottom side at I and the
casting A pressing on the top side at K effectively prevents any up and down
play of the guide.
The aforesaid latch H is held down between two ears cast into the main
casting A and a pin J runs through these ears and forms the centre for the
aforesaid latch to turn on.
The latch is prevented from going through the recess I too far by a snug
cast on to the aforesaid latch at L, and the aforesaid latch is held in position
by the catch spring M which is held between the casting A. and the latch H by
snugs N, one snug being cast on the main casting A and the other on the
latch H.
Above the latch H is fitted a second or smaller latch which is held to the
casting A by the pin Pabout this pin latch O can turn. A second pin R is
provided to prevent the latch being turned too far in either direction.
The end S of the latch being made much thicker than the other end and
having a longer leverage from the centre P always keeps the end S down as low
as possible. The bottom of S is shaped similar to T and when the guide B is
down and the apparatus is ready for work as shown in Fig. 3, the end S fits
into the hole T which is cast in the first latch H and when the guide B is lifted
for the driving bar X to be lifted out the second latch O drops into the space W
between the casting A and the first latch H, and holds latch H back, as shown
in Fig. 1.
The holes V for bolting down can be made anywhere in the casting A to suit
the shoe on the machine.
X is the driving bar which actuates the knife or cutter Y of the mower and
moves the knife to and fro in the ordinary manner of a mowing machine. The
end X¹ of the driving bar being fitted in an eye of the knife or cutter Y in the
ordinary manner and the aforesaid end of the driving bar X¹ moves to and fro
between the aforesaid steel plate C of the aforesaid guide B and the shoe
casting Z.
Z is the ordinary shoe casting of a mowing machine.
The object of the guide B is to keep the driving bar X into position and to
prevent it coming out of gear with the knife or cutter Y.
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--
1st. In a driving bar the combination of a guide for the rod to work against,
held in position by a snug on the bottom and a latch to work at the side.
2nd. In a driving bar this aforesaid latch being kept in its position by a spring,
at the back.
3rd. The use of a second latch for locking the first latch as herein described.
4th. The joint pin arranged as fixture as herein described is not liable to get
Joose and cause undue wear.
5th. The general combination and arrangement of parts constituting an
apparatus for holding the driving rod in position as herein described and
illustrated by the accompanying drawings.
