Improvements in Endless Aprons for Reaping Machines.
We, JAMES CLARKSON, of Prettsmill, in the County of Lanark, North Britain,
Farmer and Grain Dealer, and ROBERT JACK, of Hyndford Place, Lanark, in the
same County, Ironmonger, do hereby declare the nature of this invention to be as
follows, that is to say :-
Our said invention has for its object to construct endless aprons for reaping
machines in an improved manner, and so as not to be so liable to alteration by
moisture or otherwise as the canvas aprons heretofore generally employed.
In carrying out our invention according to one modification we make an endless
apron to consist of three bands of rubber-cloth, that is, rubber combined with a
woven fabric. The bands are placed one at the middle and the others at the front
and back edges. There are spaces between the bands which may be filled with
canvas; or with wooden laths; or there may be under the spaces fixed boards
having smooth upper surfaces. Across the apron or set of bands, wooden bars or
other projections are fixed to insure the carrying of the grain or cut crop in the
direction of the movement of the apron.
The number of rubber-cloth bands may be varied in different cases; and if
desired the apron may consist of a single width of rubber-cloth of suitable size.

COMPLETE SPECIFICATION.
Improvements in Endless Aprons for Reaping Machines.
We, JAMES CLARKSON, of Prettsmill, in the County of Lanark, North Britain,
Farmer and Grain Dealer, and ROBERT JACK, of Hyndford Place, Lanark, in the
same County, Ironmonger, 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, that is to say :-
Our said invention has for its object to construct endless aprons for reaping
machines in an improved manner, and so as not to be so liable to alteration by
moisture or otherwise as the canvas aprons heretofore generally employed.
In carrying out our invention according to one modification we make an endless
apron to consist of three bands of rubber-cloth, that is rubber combined with a
woven fabric. The bands are placed one at the middle, and the others at the front
and back edges. There are spaces between the bands which may be filled with
canvas; or with wooden laths; or there may be under the spaces fixed boards
having smooth upper surfaces. Across the apron or set of bands, wooden bars or
other projections are fixed, to insure the carrying of the grain or cut crop in the
direction of the movement of the apron.
The number of rubber-cloth bands may be varied in different cases; and if
desired the apron may consist of a single width of rubber-cloth of suitable size.
And in order that our said invention and the manner of performing the same
may be properly understood, we hereunto append a sheet of explanatory drawings,
to be hereinafter referred to, and showing two modifications of our improved endless
apron.
Figure, 1, of the drawings is a plan, and Figure, 2, a longitudinal vertical
section of one modification. Figures, 3, and, 4, are similar views of, and Figure, 5,

page_text: f
is a transverse vertical section of, a second modification, Figure, 3, showing the
apron as unfastened and spread out. In these drawings the same reference letters
are used to mark the same or like parts wherever they are repeated.
As shown in Figure, 1, of the drawings we make the endless apron to consist of
three bands, A, of rubber-cloth that is, rubber or it might be any suitable water-
proof material combined with a woven fabric. The bands, A, are placed, one at
the middle and the others at the front and back edges. There are spaces between
the bands, A, and to the inner side of the bands there are fixed thin wooden
laths, B, extending across the spaces between the bands. Across the outer side of
the apron or set of bands, A, wooden bars, C, are fixed to insure the carrying of
the grain or cut crop in the direction of the movement of the apron. The apron
or set of bands, A, is distended on rollers, D, and, F, by one of which it
is driven.
In Figures, 3, 4, and, 5, the apron is shown as consisting of a broad band, A,
and a narrow band, G, placed close to but separate from each other. The bands, A,
and, G, are provided at their ends with buckle straps, H, by means of which the
ends are fixed together when the apron has been placed on the rollers, D, and, F.
Across the bands, A, and, G, wooden bars, C, are fixed to insure the carrying of
the grain. The band, A, has a hem, J, formed by a part of it folded and cemented
along each edge, and the band, G, is made considerably thicker than the band, A,
to provide against wear; and it is placed at the front edge close to the finger and
cutter bars at which edge most wear takes place, whilst when worn it can be easily
replaced without renewing the entire apron.
Our invention is applicable not only to the horizontal endless apron which is
immediately behind the cutter bar and moves the crop to one side, but also to any
inclined or other endless apron comprised in the reaping machine.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :
1. Making endless aprons for reaping machines wholly or partly of rubber-cloth
or a woven fabric having combined with it rubber or other suitable water-
proof material, substantially in the manner and for the purposes hereinbefore
..described.
2. Making endless aprons for reaping machines substantially as hereinbefore
described with reference to Figures, 1, and, 2, of the accompanying drawings.
3. Making endless aprons for reaping machines substantially as hereinbefore
described with reference to Figures, 3, 4, and, 5, of the accompanying drawings.
