PROVISIONAL SPECIFICATION.
Improvements in Flexible Harrows.
I, PHILIP JOSEPH PARMITER, of Ansty, near Salisbury, in the County of Wilts,
Farmer and Harrow Manufacturer, do hereby declare the nature of this invention to
be as follows :-
My invention relates to flexible harrows of the kind described in the Specification
of former Letters Patent granted to me, dated 27th April A.D. 1885 No. 5162, and
has for its object to render the teeth of such harrows removable.
According to my invention the ends of each link, which were heretofore bent round
to form the hooks and tines, are bent so as to form hooks for connection to adjacent
links, and the end of each hook is flattened or otherwise formed so that a hole may be
punched in it to receive the shank or head of a tine or tooth. The teeth may be held
in position by nuts, wedges, keys or other suitable devices.

COMPLETE SPECIFICATION.
Improvements in Flexible Harrows.
I, PHILIP JOSEPH PARMITER, of Ansty, near Salisbury, in the County of Wilts,
Farmer and Harrow Manufacturer, 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 flexible harrows of the kind described in the Specification
of former Letters Patent granted to me, dated 27th April A.D. 1885 No. 5162, and
has for its object to render the teeth of such harrows removable.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawing, in which :-
Figure 1 is a side view of a link provided with a removable tooth according to my
invention:
Figures 2 and 3 are a plan and side view respectively illustrating a modification:
Figures 4 and 5 are a plan and side view of a link illustrating another modifica-
tion; and,
Figure 6 is a section on the line x, x Figure 4.
As shewn in Figure 1 the ends a, a of each link (which were heretofore bent
downwards to form the hooks and tines), are bent upwards so as to form hooks for
connection to adjacent links, and the end b of each hook is flattened or otherwise
formed, so that a hole may be punched in it to receive the shank or head c of a tine d,
the bar of the link is also punched to allow the tine to pass therethrough. The tines
are secured by means of nuts e.
In the modification shewn in Figures 2 and 3, the tines d are represented as being
held by clips f. Each clip is composed of two plates g, recessed to fit the bar
forming the link, and the tine is placed in a recess in the plate h, and held in
position by the hook-headed bolt k which also serves to tighten the plates upon
the bar.
In the modification shewn in Figures 4 and 5, the arrangement is substantially the
same as that shewn in Figure 1, the difference being that the tines, instead of being
secured by nuts, are secured by bending them round the end a of the link.
1, Figures 4, 5 and 6, indicates a weight which is secured to the link by hook-
bolts m.
When breaking up highways and in performing other operations where a

page_text: harrow of considerable weight is necessary, one of the said weights is advantageously
applied to each link of the harrow.
In cases where weights are to be permanently employed they may be cast onto
the links of the harrow, and the tines may be secured in sockets formed in such
weights.
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. A flexible harrow of the kind hereinbefore described provided with removable
teeth, substantially as described.
2. The combination with a harrow of the kind herein before described provided
with removable teeth, of weights, substantially as, and for the purpose, described.
3. The manufacture and use of flexible harrows of the kind herein before described
provided with removable teeth, substantially as herein before described and illustrated
in Figure 1, Figures 2 and 3 and Figures 4 and 5 of the accompanying drawing.
Dated the 18th day of August 1890.
