PROVISIONAL SPECIFICATION.
An Improvement in Hay-making Machines.
I, HENRY BEARE, of Sunny Croft, Paignton, in the County of Devon, Agricultural
Engineer, do hereby declare the nature of this invention to be as follows:-
My improvement in haymaking machines relates to the mode of mounting the
rake-heads of the revolving drum or cylinder; and it has for its object to avoid the use
of the separate hinge joints usually employed and the invention consists in pivoting
the cross-bar in which the rake teeth are fixed directly in a tubular T piece fixed to
the end of a radial tubular arm of the rake drum. For this purpose, the said cross-
bar is made of round section and either of wood or of metal tube and it is inserted in
the socket in which it is to be pivoted before the rake teeth are fixed in it. The
socket in which the rake head is thus pivoted is centrally slotted in the plane of
rotation of the rake head to which is affixed a projection that plays in. this slot and
has flattened surfaces against which bears a spring affixed to the radial arm for the
purpose of holding the rake head. either in its operative or inoperative position whilst
allowing it to be readily: turned from the one to the other position as required and
also permitting the rake teeth to yield should they encounter an obstacle when
in work.
The improvement is applicable both to forward and backward action machines.
COMPLETE SPECIFICATION. . .
An Improvement in Hay-making Machines.
I, HENRY BEARE of Sunny Croft, Paignton, in the County of Devon, Agricultural
Engineer, 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 improvement in haymaking machines is applicable both to forward and back-
ward action machines, and it relates to the mode of mounting the rake heads of the
revolving drum or cylinder.
It has for its object to avoid the use of the separate hinge-joints usually employed,
and the invention consists in pivoting the rake head, or cross bar in which the rake teeth
are fixed, directly in a tubular T-piece fixed to the end of a radial tubular arm of the
rake drum and in applying a spring to act on the rake-head in such manner as to hold
the rake teeth either in the operative or inoperative position and allow them to yield
should they encounter an obstacle when in work.
The Invention is illustrated in the accompanying drawings, forming part of this
specification, which shew a view of as much as one of the rake heads as is necessary
to the explanation of the invention.
Figure 1 is a rear elevation, and figure 2 a sectional elevation, of one of the arms
of the drum and part of the rake-head mounted thereon.
For the purpose of my improvement, the rake-head or cross-bar A is made of round
section and either of wood or of iron tube and it is pivoted in a central T socket B in
which it is inserted before the rake teeth a are fixed in it. The central member B¹ of
this socket B is screwed to a radial arm (, also of iron tube, which is screwed into,
or otherwise secured to, the boss of the drum. The socket B is centrally slotted at
in the plane of rotation of the rake-head and a piece of metal d is bolted to the bar A

which projects through, and plays in, this slot. It has projecting corners or angles d' d'
and a flat d³ and a spring D affixed to the radial arm bears against it for the purpose
of holding the rake head A in whichever of its two positions it may be placed.
It is shown with the rake teeth a in the operative position in full lines and in the
inoperative position at in dash and double-dotted lines, and the rake teeth may be
readily turned from the one to the other position as required. In the inoperative
position a' the teeth are in a plane at right angles to the arm C and are held in that
position by the spring D bearing against the end d' of the flat projection d³, a stop e
then abutting against the end of the slot b.
Should the rake teeth, when in work, strike against a stone or other obstacle to the
rotation of the drum, the spring will allow them to yield, as shewn at a² in dash and
single dotted lines, and after passing the obstacle will return them to the working
position.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is;
1. In a haymaking machine, pivoting the rake head, or cross bar in which the rake
teeth are fixed, directly in a tubular socket piece fixed to the radial arm of the drum,
substantially as specifled.
2. In a haymaking machine, the combination, with the rake head pivoted directly
in a central slotted T-socket, as described, of an angular projection fixed to it, working
in a slot of the T piece and a spring applied to act thereon, substantially as, and for
the purpose, specified.
