PROVISIONAL SPECIFICATION.
Improvements in the Couplings and Fastenings of the Canvases of
Sheaf Binders.
1 RICHARD TIMMIS of Westley in the County of Salop, Farmer do hereby
declare the nature of this invention to be as follows:
A loop is formed in or near each end of the canvas by turning a part of it back
upon itself and securing the edges by any suitable device. This loop extends from
side to side of the canvas across its entire width and is of sufficient size to admit
a rod or bar of metal, wood or other material. Suitable apertures are provided at
intervals in the said loop thus exposing the rod or bar aforesaid and leaving
sufficient space at the back thereof to admit of straps being inserted. The apertures
aforesaid are exactly opposite each other and the straps are placed in position
embracing each rod or bar and drawing it nearer the other. The strain upon the
canvas is thus equal and continuous over its entire area causing the canvas.to travel
in an even and regular motion over the rollers provided for that purpose and
obviating the chances of breaking through increased tension caused by dampness
of the canvas and facilitating the slackening or tightening of the canvas to meet
varying conditions of temperature as required. The overlap of the canvas being
also suitably secured.

1, RICHARD TIMMIS, of Westley, in the County of Salop, Farmer, 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 consists in the herein-described improvements in the couplings
and fastenings of the canvas travelling bands which are used in sheaf binding
machines to convey the cut corn from one part of the machine to another part.
Heretofore it has been customary to secure the ends of the said canvas travelling
bands together by straps which have been sewn and rivetted to the canvas near the
ends thereof at intervals. Those parts of the straps which are sewn and rivetted
to the canvas do not run evenly over the pulleys or rollers, and the strain on the
canvas is not uniform as it is greatest at those parts where the straps are fixed;
moreover when a strap breaks (as is often the case) there is a great waste of time
in removing the old strap from the canvas and in fixing on the new strap, all of
which defects it is the object of my invention to overcome.
I will describe my invention by referring to the accompanying drawings on
which
Fig. 1 represents in plan, and Fig. 2 in longitudinal section, the ends of one of
the said canvases with my invention applied;
Fig. 3 shews in plan and Fig. 4 in longitudinal section one of the said ends of
the canvas travelling band separately.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.

page_text: The ends of the canvas travelling band which are required to be secured
together are marked respectively A and A. The usual strips of wood, which
are nailed or otherwise secured at intervals across the outer surface of the
canvas band to help in moving along the cut corn or other cut crop, are
marked B.
In carrying out my invention I form a loop in or near each end of the canvas
travelling band extending across the same from side to side and in each of these
loops which are marked respectively C' C² I insert a stout wie or thin rod D. The
said loops CC2 are by preference formed by folding back the end of the canvas
upon itself and then securing the folded back part by sewing or by other means, as
by two of the wooden strips B (as shewn on my drawing) to which the canvas is
nailed. Suitable apertures E are provided in each of the said loops at regular
intervals so as to expose the wires or rods D and leave sufficient space at the back
thereof to admit of the straps Fbeing inserted, the apertures in one end of the
canvas being opposite those in the other end. The two ends A¹ A2 of the canvas
are connected together by ordinary buckled or other straps F (Figs. 1 and 2) which
are threaded through the holes E so as to embrace the wires or rods D, the buckles
of the straps being on the outside of the canvas as shewn. The canvas moves in
the direction shewn by the arrow.
.
The wires or rods D transmit the strain of the straps F uniformly along the
whole width of the canvas travelling band which causes the band to travel with
an even and regular motion over the rollers and the risk of any of the straps
breaking through the shrinking of the canvas is very considerably reduced. More-
over.if one of the straps breaks it can be very quickly removed and replaced
by a new one.
The end A' of the canvas has the usual flap G extending all across to cover the
straps and the space between the two ends A'A' of the canvas. This flap is shewn
only in the sectional views Figs. 2 and 4.
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 :-
In combination with a canvas travelling band for use in sheaf binders, a stout
wire or other rod fitting in a transverse loop at each end of the said band,
and straps engaging with the said rods at intervals and adapted to draw and
maintain the two ends of the said band together substantially as hereinbefore
described.
