THOMAS CHARLES SARGEANT, Cattle Market Road, Northampton, Engineer,.
THOMAS PHIPPS, 169 Bridge Street, Northampton Gentleman, do hereby declare
the nature of this invention to be as follows:-
This invention relates, to the mode of jointing the cutter bar to the main frame
in order that the former may be accurately adjusted with the latter, & also that
the knife sections which are vibrated by a crank and connection bage a uniform or
fixed throw relative to the fingers attached to the said cutter bar. This is obtained
by jointing the cutter bar connection to the sleeve carrying the crank shaft the
cutter bar connection radiating from the centre of the said crank shaft.
The adjustable tie rod which has a fixed relation to the cutter bar connection,
connects the finger bar shoe. to the main frame, the latter having a forward
extension forming a chamber in which the crank revolves. To the said extension,
& centrally with the crank-shaft the tie rod is jointed; the cutter bar connection
being jointed to the main frame in the rear of the crank, and radiating from crank
shaft centres, & the tie rod radiating from crank shaft centres, but jointed to the
main frame in front of the crank, the crank shaft centre being common to the
cutter bar connection & the tie rod; the former being on one side, & the latter on
the opposite side of the crank.

THOMAS CHARLES SARGEANT Cattle Market Road Northampton Engineer,
THOMAS PHIPPS, Gentleman, 169 Bridge Street, Northampton, 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 the method of connecting the cutter bar to the main
frame, & consists in the novel construction & arrangement of the connection
between the two. This connection differs from all others inasmuch as the crank-
shaft, bracket & tie rod radiate upon common centres in the main frame, & that
the tie rod & bracket are jointed to the main frame on opposite sides of the crank
which drives the knife. The chief object of this arrangement is to keep the throw
of the knife relative to the finger constant when the machine is traversing uneven
ground, and to obtain an accurate and rigid connection of the cutter bar to the
main frame. The accompanying drawing is a plan of the machine shewing only
part of the cutter bar, & those parts necessary. For convenience we make the tie
rod adjustable by forming a thread upon one end which screws into a corresponding
thread on the lug.
A is the bracket jointed upon the crankshaft sleeve D of the main frame C,
B the cutter bar & a the joint, E the crank & F the tie rod. Now it will be seen

page_text: that as the cutter bar B' rises and falls it radiates upon the crankshaft centre G
& thereby ensures a constant throw of the knife relative to the fingers of the cutter
bar at all elevations. We may construct the bracket A. & tie rod F in one piece,
this invention will then form the subject of Claim No. 1..,
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a mowing machine the cutter bar B of which is connected with the main
frame C by a connecting link or bracket AF, one end of said connecting link A F
being jointed to the cutter bar B, while the other end. is jointed to the main
frame C on either side of the crank E, the said connecting link. AF radiating, upon
the crankshaft centre G substantially as described.
2. In a mowing machine the cutter bar B of which is connected with the main
frame by a connecting link or bracket A, one end of the said bracket A being
jointed to the cutter.bar B, & the other end to the crankshaft sleeve of the main
frame D, on the one side of the crank E; while the tie rod Fone end of which is
jointed to the cutter bar Brand. the other end to the main frame D on the bther
side of the said crank E. The crankshaft G bracket A & tie rod F radiating"
upon cominon centres in the main frame C, substantially as described.
Dated this Thirteenth day of January 1896.
