IMPROVE- MENTS IN HAYMAKING MACHINES
Year: 1872

page_text: LETTERS PATENT to Henry Beare, of Newton Abbot, in the County
of Devon, Agricultural Engineer, for the Invention of "IMPROVE-
MENTS IN HAYMAKING MACHINES."
Scaled the 8th November 1872, and dated the 2nd September 1872.
PROVISIONAL SPECIFICATION left by the said Henry Beare at the
Office of the Commissioners of Patents, with his Petition, on the
2nd September 1872.
I, HENRY BEARE, of Newton Abbot, in the County of Devon,
Agricultural Engineer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN HAYMAKING MACHINES," to be as follows:-
My improvements in haymaking machines have for their object to
simplify and cheapen the construction of the machines, and at the same
time to increase the efficiency of their action. Hitherto in baymaking
machines the barrel carrying the tines has usually been mounted
between the carrying wheels, and its length has necessarily been less

page_text: than the width of the wheels apart, so that so much of the crop as lies
in the track of the wheels is pressed down by their passage; but
according to my Invention I dispose the tine shaft at the rear of the
machine, whereby I am enabled to increase its length beyond the width
of the main framing, and so extend the action of the tines to that
portion of the crop over which the wheels have passed.
The heads carrying the tines are mounted on a shaft supported at the
rear of the machine in bearings hung from the main framing, which is
extended laterally behind the carrying wheels to permit of the increased
length of the tine shaft; the latter is driven from the shaft or axle of
the carrying wheels through an intermediate shaft and bevel gearing;
the carrying wheels and their axle turn together, and on the latter near
the centre are mounted bevel wheels of different diameters for imparting
different speeds, either of which can be put in gear with the inter-
mediate shaft as required, by the increased speed which may be imparted
to the tine shaft two heads of tines are sufficient instead of four and the
machine may be made much lighter than usual.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Beare in the Great Seal Patent Office on
the 1st March 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BEARE, of Newton Abbot, in the County of Devon, Agricultural
Engineer, send greeting.
WHEREAS. Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of September, in the year
of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Henry Beare, Her special
licence that I, the said Henry Beare, executors, administrators, and
assigns, or such others as I, the said Henry Beare, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and

page_text: vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN HAYMAKING MACHINES," upon the condition (amongst others) that I,
the said Henry Beare, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar

vend, within the United Kingdom of Great Britain and Ireland, the

Patent
NOW KNOW YE, that I, the said Henry Beare, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Sheet of
Drawings and to the letters and figures marked thereon (that is to say):-
My improvements in haymaking machines have for their object to
simplify and cheapen the construction of the machines, and at same
time to increase the efficiency of their action. Hitherto in haymaking
machines the barrel carrying the tines has usually been mounted.
between the carrying wheels, and its length has in such cases been less.
than the width of the wheels apart, so that so much of the crop as lies.
in the track of the wheels is pressed down by their passage; but according.
to my Invention I dispose the tine shaft at the rear of the machine,
whereby I am enabled to increase its length beyond the width of the
main framing to any required extent, and so extend the action of the
tines to that portion of the crop over which the wheels have passed.
I would remark that I am aware of Salmon's Patent, No. 4047,.
1816; but my machine differs from this inasmuch as the tine shaft in.
my machine is mounted in two brackets, one at each end, hung from a
lateral extension of the main framing behind the carrying wheels,
whereby I am enabled to place the said brackets or bearings at any
width apart to accomodate a tine shaft of greater length than the
width of the main portion of the framing, which was not possible in
Salmon's machine; moreover, the diameter of the rakes being com-
paratively small I am enabled to hang the shaft in perpendicular.

page_text: supports below the main frame instead of as in Salmon's mounting it
in bearings in the horizontal plane of the said frame.
The tine shaft may be driven from the shaft or axle of the carrying
wheels through an intermediate shaft and bevel gearing; the carrying
wheels and their axle turn together, and if bevel gearing be employed,
near the centre of the axle are mounted bevel wheels of different
diameters for imparting different speeds, either of which can be put in
gear with the intermediate shaft, as required; by the increased speed
which may be imparted to the tine shaft two or three heads of tines are
usually sufficient (but four or more may be employed if desired), and
the machine may be made much lighter than usual; spur gearing may
however be substituted for the bevel gear, a spur wheel on the carrying
wheel axle gearing with a pinion on an intermediate shaft which
carries another spur wheel gearing with a pinion on the tine shaft.

page_text: may form an integral part thereof by being bolted across the ends of the
side frames A. H are the heads of tines of which three are shown; they
are constructed and mounted on shaft E much in the usual manner, and
are divided at the middle of their length for the gearing by which the
tine shaft is driven; I is a bevel wheel keyed on axle C, and having an
inner bevelled ring of teeth I' of smaller diameter, the teeth (a few only
are shown) of both rings being slightly askew, as shown, on account of
the oblique position of the intermediate shaft K, which passes the axlo
O for the purpose of gearing with the forward part of rings I, I', and
thereby increase the pressure on the horse's back, in order to assist in
counterbalancing the tine shaft and its adjuncts; K is the intermediate
shaft hung in brackets K', from the main frame A; L, L', are two
bevel pinions in gear with the bevelled rings I, I, respectively; these
pinions are loose on shaft K between suitable collars, which shaft
receives no motion until geared with one or other pinion by means of a
clutch M placed between them and sliding on shaft K with groove and
key so as to turn therewith; N, clutch lever handle pivoted at N¹ and
placed within convenient reach of the driver's hand; O is a bevel wheel
keyed at the other end of shaft K gearing with a corresponding pinion P
keyed on tine shaft E.
By means of rings I, I', and pinions L, L², the tine shaft may-be
driven in the same direction at either of two speeds.
In Figures 4 and 5 I is a spur wheel on wheel axle C gearing with
a pinion L on an intermediate shaft K, which also carries a spur wheel O
gearing with a pinion P on the tine shaft E.
Having described the nature of my Invention, and in what manner
the same is to be performed, I declare that what I claim as my Invention
to be protected by the herein-before in part recited Letters Patent is,-
1st. Supporting the extremities of the tine shaft in bearings in
brackets hung from an extension of the rear part of the machine frame,
which projects laterally beyond the rest of the frame and beyond the
travelling wheels, whereby I am enabled to make the tine shaft bearings
as much wider apart than the travelling wheels as may be required,
substantially as and for the purpose set forth, whether the tine shaft be
driven by bovel gearing or otherwise.

page_text: 2ndly. The combination with a tine shaft, supported as herein specified,
of the intermediate shaft K carrying pinions L, L', gearing with the two
rings I, I', on wheel axle for communicating fast or slow motion to said
tine shaft, substantially as herein shown and described.
In witness whereof, I, the said Henry Beare, have hereunto set 5
my hand and seal, this Twenty-eighth day of February, in the year
of our Lord One thousand eight hundred and seventy-three.
HENRY BEARE. (L.S.)
