Improvements in Cultivators.
I, REGINALD WALTER BARKER, of Monument Chambers, King William
Street, London, England, Patent Agent, do hereby declare the nature of this
invention to be as follows: :―
My invention relates to improvements in what are known as "double shovel
cultivators," the object being to provide a simple and economical construction of
the same, whereby the sheths carrying the shovels may be laterally adjusted so as
to vary the distance between the furrows turned thereby.
The sheths which are made of spring metal and have their rear ends curved
downwardly and provided with the ordinary shovels.
The handles have their front ends connected with the sheths by means of
clips. Intermediate of their ends these handles are connected with the curved
portions of the sheths by means of arms, being secured to the latter at their lower
ends and having their upper ends provided with a series of holes or apertures,
through which and the handles pass bolts or pins by which they are adjustably
secured thereto, so as to vary the height of the shovels.
Intermediate of the front ends of the handles and the arms is an adjustable
device for laterally adjusting the distance of the sheths from each other. This
device consists of two metallic plates, the outer ends of which are bent downwardly

and then inwardly, forming clamps which embrace the sheths.
overlap each other and are provided with a series of holes or apertures through.
which passes a headed bolt provided with a binding nut, provided with an operating
handle by which they are held together, being also provided with a clamp consisting
of a metallic loop, which embraces the same and also aids in holding them. One of
the plates has its end reduced and turned upward and is inserted in one of the holes
of the other plate, thereby preventing the said plates twisting one upon the other,
should by any possible means the clip or clamp slide past the end of the lower
plate. The plates are also provided with screw bolts which pass therethrough
and through the inwardly bent ends, whereby they are securely attached to the
sheths.
The operation will be readily understood.
When it is desired to increase the distance between the furrow formed by the
shovels, the bolt is loosened by removing the nut with a wrench, allowing said bolt
to be withdrawn. The sheths are then spread apart, and when the required
distance has been reached the bolt is again inserted in the apertures in the plate
and secured in place by the binding nut.

Improvements in Cultivators.
0 I, REGINALD WALTER BARKER, of Monument Chambers, King William
Street, London, Middlesex, Patent Agent, 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 improvements in what are known as
TD 017
"double-shoveļ

page_text: cultivators," the object being to provide a simple and economical construction of
the same, whereby the sheths carrying the shovels may be laterally adjusted so
as to vary the distance between the furrows turned thereby.
The invention consists in the novel construction and combinations of parts herein-
after fully described and claimed.
In the accompanying drawings,
Figure 1 is a perspective view of a plough constructed in accordance with my
invention.
Fig. 2 is a detail view of the device for adjustably connecting the sheths, and,
Fig. 3 is a sectional view of the sheth adjusting devices.
The sheths 3, are made of spring metal and having their rear ends curved
downwardly and provided with the shovels 4.
The numeral 55 designate the handles, having their front ends connected with the
sheths by means of clips 66. Intermediate of their ends these handles are connected
with the curved portions of the sheths by means of arms 77, secured to the latter at
their lower ends and having their upper ends provided with a series of holes or
apertures 88 through which and the handles pass bolts or pins 99, by which they
are adjustably secured thereto, so as to vary the height of the shovels.
Intermediate of the front ends of the handles and the arms 77 is an adjustable
device for laterally adjusting the distance of the sheths from each other. This
device consists of two metallic plates 10 10, the outer ends of which are bent
downwardly and then inwardly, forming clamps 12 12, which embrace the sheths.
These plates overlap each other and are provided with a series of holes or
apertures 13 13, through which passes a headed bolt 14, provided with a binding
nut 15, provided with an operating handle by which they are held together, being
also provided with a clamp 16, consisting of a metallic loop, which embraces the
same and also aids in holding them. One of the plates 10 has its end reduced, and
turned upward and is inserted in one of the holes of the other plate, thereby
.preventing the said plates twisting one upon the other should by any possible
means the clip or clamp 16 slide past the end of the lower plate. The plates are
also provided with screw bolts 17 17, which pass therethrough and through the
inwardly bent ends, whereby they are securely attached to the sheths.
The operation will be readily understood. When it is desired to increase the
distance between the furrow formed by the shovels, the bolt 14 is loosened by
removing the nut 15, allowing said bolt to be withdrawn. The sheths are then
spread apart, and when the required distance has been reached the bolt is again
inserted in the apertures in the plate and secured in place by the binding nut.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
An improved cultivator comprising spring sheths, provided with shovels, the
handles secured to said sheths by the clips, and the adjustable arms, of the
adjustable plates having downwardly and inwardly turned outer ends overlapping
each other and provided with a series of registering apertures, the inner end of
one of said plates being provided with an upturned lip to project into one of the
apertures in the other plate, the bolts and nuts for securing said plates together,
and the bolts and nuts for securing said plates to the sheths, substantially as
described.
