IMPROVEMENTS IN HAYMAKING MACHINES
Year: 1874

page_text: LETTERS PATENT to William Andrews, of Melksham, in the County
of Wilts, Agricultural Implement Maker, for the Invention of
"IMPROVEMENTS IN HAYMAKING MACHINES."
Scaled the 24th November 1874, and dated the 29th September 1874.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
HAYMAKING MACHINES," and have pétitioned Her Majesty to grant unto
0 me, my executors, administrators, and assigus, Her Royal Letters

page_text: Patent for the same, and have made solemn Declaration that I am the
true and first Inventor thereof.
NOW KNOW YE, that I, the said William Andrews, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement, reference being had to the accompanying Drawings and to
the figures and letters marked thereon, that is to say :-
My said Invention relates to certain improvements upon an Invention
for improvements in haymaking machines, for which Letters Patent
were duly granted to me bearing date the 8th day of July 1867
No. 2002, and which Letters Patent are now subsisting and unim-
peached in respect of their legal validity.
The said improvements consist in so arranging the gearing of the
machine, that any desired speed may be given to the tinc axle either
when working in forward or back action (that is to say), to throw the
grass or hay over or behind the tine axle), by moving the main driving
wheel which is an external and internal cog wheel into two pinions.
The said pinions can be taken off by removing a nut or key or by any
other known method and appliance, and larger or smaller pinions fixed 2
on the same spindle which will give different speeds to the tine axle.
The said main driving wheel works ou au axle which is fixed into or cast
on a lever which rocks on a pivot at the lower or top part of each main
frame casting; or if preferred the axle is fixed or cast on a block which
slides on the main frame casting into the pinions as herein-before
mentioned. The said sliding wheel and axle are kept into either the
forward or back action gear by a spring catch or other suitable
mechanical contrivance as will be well understood.
A further part of my said Invention consists in the employment of an
india-rubber spring which pulls a lever attached to the tiue rake head,
and keeps the rake tines in position instead of the steel springs which
have been previously used for the same purpose.
I will now proceed to refer to the accompanying Drawings from
which the nature of my said Invention will be more clearly understood.

page_text: Figure 1 is a front view shewing my improvements in detail; Figure 2
is an end view, and Figure 3 a plan of the same. The same letters of
reference indicate similar parts in the several Figures.
A is the main driving cog wheel cast with or fixed to the road wheel
5 A'; this wheel works loose on the axle B, which axle is fixed into or
cast on the lever C, which lever works on a pivot D of the main frame
or side casting E. When this main wheel A is slid into the pinion F
forward action is obtained, and by removing the pinion F and fixing a
smaller or larger pinion in its place a quicker or slower speed is given to
the tinc axle F' which runs on the fixed axle F. When the main
wheel A is slid into the pinion G back action is obtained, and by
removing the pinion G and fixing a smaller or larger wheel in its placc a
quicker or slower speed is given to the tine axle. When the main wheel
A is between the two pinions F and G the tines are out of gear and at
rest for travelling. These two pinions F and G are fixed on two spindles
Hand I which run loose in bearings I' of the main frame casting, and
on the other end of the spindles H and I are keyed two pinions J and K
which gear into a pinion L fixed or cast on the same axle F¹; C¹ is a
spring catch attached to the handle of the lever C, and which spring
catch gears into a catch plate C", by which means the gearing apparatus
is held in its proper position.
Figure 4 represents the application of the india-rubber spring before-
mentioned with the lever and adjusting screw for regulating the position
of the tines. The spring is shown at M, by which spring a lever N
attached to the tinc rake head Q is pulled and thereby regulates the
position of the tines.
Having thus declared and ascertained the nature of my said Invention
and in what manner the same is to be performed, I would observe in con-
clusion that what I consider novel and original, and therefore claim as
constituting my said Invention are,-
First. The combination and arrangement of parts and mechanism in
the construction of haymaking machines, whereby any desired speed is
given to the tine axle either for forward or back action, substantially as
and for the purposes herein-before described and set forth or any merc
modifications thereof.

page_text: And, secondly. The arrangement and use of india-rubber springs for
keeping the rake tines in position, substantially as herein-before
described and set forth or any mere modifications thereof.
In witness whercof, I, the said William Andrews, have here-
unto set my hand and scal, this Twenty-sixth day of September,
in the year of our Lord One thousand eight hundred and
seventy-four.
WILLIAM ANDREWS. (L.S.)
