PROVISIONAL SPECIFICATION.
An Improved Implement or Machine, chiefly designed for
Breaking Up Roads.
I, PHILIP JOSEPH PARMITER, of Ansty, Salisbury, in the County of Wilts,
Agricultural Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an implement or machine specially designed for
harrowing or breaking up highways or roads but also applicable for other
harrowing purposes.
In carrying out my invention I provide a harrow formed of a series of links
each of which links carries an upright bar or bars forming a guide adapted to
carry one or more weights according to the nature of the work to be performed.
To the upper end or ends of the bar or bars of each link is attached one end of a
chain the other end of which is secured to a drum or shaft carried by a carriage
above the harrow in such a manner that by rotating the said drum the links of the
harrow may be raised or lowered as required.
The shafts or drums carrying the various links or series of links are provided
with ratchet wheels, with which pawls engage, or are otherwise suitably arranged
to enable them to be held at any desired height.
In practice I advantageously form the links of the harrow in the manner described
in the Specification of former Letters Patent granted to me No. 16400 of 1889.
The carriage hereinbefore referred to is advantageously mounted on three
wheels the front one of which forms the steering wheel.
Dated the 25th day of March 1891.

COMPLETE SPECIFICATION.
An Improved Implement or Machine, chiefly designed for
Breaking Up Roads.
I, PHILIP JOSEPH PARMITER, of Ansty, Salisbury, in the County of Wilts,
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 :-
This invention relates to an implement or machine specially designed for
harrowing or breaking up highways or roads but also applicable for other
harrowing purposes.
In carrying out my invention I provide a harrow formed of a series of links
linked together, each of which links is connected to an upright bar or bars
forming a guide adapted to carry one or more weights according to the
nature of the work to be performed. To the upper end or ends of the bar or
bars of each link is attached one end of a chain the other end of which is
secured to one of a series of drums or shafts carried by a carriage above the
harrow in such a manner that by rotating the said drums the links of the harrow
may be raised or lowered as required.
The shafts or drums carrying the various links or series of links are provided
with ratchet wheels, with which pawls engage, or are otherwise suitably arranged
to enable them to be held at any desired height.
In practice I advantageously form the links of the harrow in the manner
described in the Specification of former Letters Patent granted to me No. 16400
-

page_text: of 1889, but instead of forming the tines integral with the links as in the said
Specification, I alvantageously attach them to the lowest weight.
The carriage herein before referred to is advantageously' mounted on three wheels
the front one of which forms the steering wheel.
To enable my invention to be fully understood, I will describe how it can be
carried into practice by reference to the accompanying drawings, in which:
Figures 1 and 2 are respectively a plan and side elevation of an implement or
machine constructed according to my invention for breaking up roads and for like
purposes.
Figures 3 and 4 are respectively a front elevation and a plan of one of the links
with a weight connected thereto.
Figure 5 is a plan of a loose weight to be added to the links as required.
a is the carriage or frame of the implement, bb the side carrying wheels and < the
steering wheel. d is a draught hook by which the implement can be connected to
and drawn along by a traction engine or the like.
ee are the links which are connected by chains el e¹ or the like to a frame a¹
depending from the frame a, and are advantageously of the form and linked
together in the manner described in the Specification hereinbefore mentioned and
are arranged in rows or series. ff are the upright bars for carrying the weights,
two of which bars are advantageously employed in connection with each link and
connected together by a cross-bar g. Each link and its bars are advantageously
connected together by a weight the said weight being formed in two parts h¹ h¹
so as to grip the link between them, the bars ff serving to hold the said. parts
together by screw-threads and nuts as shewn.
ii are the tines which engage with and break up the road surface and which are
fixed in the weight h h.
For increasing the weight on the tines ii, additional weights; (one of which is
shewn at Figure 5) are placed upon the weights hh, slots jj being formed in the
said weights which slots embrace the bars ff.
kk are the chains connected at one end to the bars ff, the connection being
made through the medium of the cross-bars g g as shewn."
1 are the drums or shafts to each of which the other ends of the chains k k
of each row or series of links are attached, the said drum being carried in
bearings m m on the frame a and provided with levers n n.
oo are the ratchet wheels on the drums 1.1, and p p are the pawls engaging with
the said wheels so as to maintain the weighted tines ii at any desired height when
raised out of work by rotating either of the drums by its lever n.
હૈ
In order to raise all the weighted tines out of work simultaneously, chains or
rods are employed for connecting when required the levers n n together and to
a barr adapted to slide in guides s s on the frame a, the said bar being adapted to
be connected to the traction engine or the like operating the implement so as to be
drawn forward and effect the said raising of the tines.
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 :-
1. An implement or machine for breaking up roads and for like purposes com-
prising a frame adapted to run on wheels, weighted tines arranged in rows or series
linked together, and to the frame, and means whereby the said rows or series of
tines can be independently or collectively raised out of work, substantially as
herein before described.
2. The improved implement or machine for breaking up roads hereinbefore
described and illustrated in the accompanying drawings.
