PROVISIONAL SPECIFICATION.
Improvements in Connecting Knife Bars to Heels in Mowing and
Reaping Machines.
I THOMAS STIRRUP of 6 Charles Street Leigh, in the County of Lancaster,
Engineer do hereby declare the nature of this invention to be as follows:-
The object of the invention is to so connect knife bars to heels in mowing and
reaping machines that the rivets or agents employed for securing these parts together
shall be freed from end or back strain or both.
Under the first part I make the knife bar with one or more projections which fit
into a transverse slot or slots in the heel to take end strain; or the projection or pro-
jections may be on the heel and the slot or slots in the knife bar.
Under the second part I make the heel with a flange or flanges which fits or fit
behind the cutter bar to take back strain.
Under the third part I combine the improvements set forth in the above first and
second parts to take both end and back strain.
Under the fourth part I make the cutter bar or heel with projections and the heel
or cutter bar with recesses, into which the projections fit to take both end and back
strain.
Under the fifth part, I combine the improvements under the fourth part with any of
the improvements set forth under the first second and third parts.
The cutters bar and heels are of any usual or suitable construction and are secured
together by rivets bolts or equivalent agents.
Dated this 9th day of October 1886.

I THOMAS STIRRUP of 6 Charles Street, Leigh, in the County of Lancaster,
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:-
The object of the invention is to so connect knife bars to heels in mowing and
reaping machines that the rivets or agents employed for securing these-parts together
shall be freed from end or back strain or both.
Under the First part I make the knife bar with one or more projections which fit
into a transverse slot or slots in the heel to tako end strain or the projection or pro-
jections may be on the heel and the slot or slots in the knife bar.
:
Under the Second part I make the heel with a flange or flanges which fits or fit
behind the cutter bar to take back strain.
Under the Third part I combine the improvements set forth in the above first and
second parts to take both end and back strain.
Under the Fourth part, I make the cutter bar or heel with projections and the-heel
or cutter bar with recesses into which the projections fit to take both end and back
strain.
Under the Fifth part I combine the improvements under the fourth part with any
of the improvements set forth under the first, second and third parts.
The cutter bar and heels are of any usual or suitable construction and are secured
together by rivets bolts or equivalent agents.
In the views herewith-showing my various improvements in connecting knife bars
to heels in mowing and reaping machines-a denotes the knife bar, 6 the heel, c the
knife, and d rivets or like securing agents.
First part, Figure 1. is an elevation showing the knife bar with a projection e which
fits into a slot in the heel. In figure 2. there are two projections e on the heel which
fit into two slots in the knife bar.
Second part, Figure 3 is a plan and Figure 4. a transverse section where the heel b
is provided with a flange which fits behind the knife bar a.
Third part, Figure 5. is an elevation, Figure 6 a plan and Figure 7. an elevation.
Here the improvements above shown under the letters e and f. are combined in same
apparatus.
Fourth part, Figure 8. is a transverse section and Figure 9 an elevation where
the heel b has projections g which fit into recesses in the knife bar.
Fifth part, Here figure 10 is a transverse section 11 an elevation and 12 a plan
showing the combination of projections e, flanges f, and projection g all in the same
apparatus.

page_text: Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, I declare that what I claim in
connection with mowing and reaping machines is :-
First The combination with the knife bar a. and heel b of projections e fitting into
transverse recesses substantially in the manner and for the purpose set forth.
Second-The combination of the heel b, and flange f. with the knife bar a
substantially in the manner and for the purpose set forth.
Third The combination of the improvements under the first and second parts.
Fourth-The combination of the knife bar a. and heel b with projections and recesses
g substantially in the manner and for the purpose set forth.
Fifth The combination of the improvements set forth under the fourth part with
any of the improvements under the first, second or third parts.
