I, WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, in the County of Lancaster, and 323,
High Holborn, in the County of Middlesex, Civil Engineer, do hereby declare the
nature of this invention to be as follows:-
The base-frame of harvesters, especially those which have an elevator and support
automatic binding apparatus, carries an enormous weight and is subject to great
torsional strain, which tend to twist it and disorganize the mechanism mounted
upon it.
Heretofore this frame has universally been made of wood, but in one or two
instances, perhaps, that portion immediately beneath the binding apparatus and con-
stituting the wheel-frame has been of heavy metal casting. Tubular metal bars have
been employed upon the elevator-frame on account of their strength and lightness, to
afford means for the attachment of the adjustable binding device, and for this purpose
have been found eminently suitable, their cylindrical shape offering no objection, but
rather facilitating such adjustable attachment, making them good ways for the runners
of the binder to slide upon. But this very cylindrical outline renders them unsuit-
able for use in a base-frame to which other and heavier framework is to be applied
and upon which tremendous torsional strain will come, since the fastening bolts will
receive no assistance and will be in no wise braced by this shape, but must themselves
alone sustain the entire strain.
In the present invention it is proposed to replace the base-sills and girts of the
harvester frame by sills and girts of tubular metal, square or rectangular, or prac-
fically so, in cross section, which will afford the same facility for attachment between
themselves and of other parts of the frame-work and the same or increased strength
of joint at such points of attachment as do the square wooden beams and timbers
heretofore used for the purpose, and will therefore involve no further reorganization
of the superposed parts.

page_text: Since the greatest weight and greatest strain is in the immediate vicinity of the
main-wheel, which is located under the clevator, these tubular bars of rectangular
cross section may be beneficially employed in the base frame of the elevator alone,
this also including the wheel-frame, leaving the front and rear sills of the platform-
frames of wood, as heretofore, overlapping and bolted to the front and rear sills of
the elevator-frame, but it is preferred to carry the tubular construction into the rear
platform-sill and divider-girt at least, and the invention will be thus described
herein.
A further feature of the invention relates to the tightener for the platform-apron
and more particularly to certain improvements upon the tightener made the subject of
letters patent of the Kingdom of Great Britain No. 7,855, dated June 29, 1885 as
will presently be explained.
Now proceeding to describe the invention, the front sill of the platform-frame is,
or may be, a bar of wood, as usual, forming a back to an angle-iron finger-bar which
which has its horizontal web uppermost and flush with the upper edge of said sill
and, being bolted thereto at intervals, strengthens and braces it. The rear sill, as
already intimated, it is preferred to construct as a tubular bar of rolled or forged iron,
rectangular in cross-section, occupying the place of the customary wooden rear plat-
form-sill. At its outer or stubble end this sill receives a metal bracket having snugs
at its foot whereby it saddles and closely embraces the upper side of the sill, and at
its top a slightly oblique seat for the rear end of the divider-girt, which likewise is a
rectangular tubular bar, and is secured at this point by a bolt passing through the
bracket and rear sill, thence extends forwardly past the finger-bar and to the point
of the divider, being suitably supported adjacent to the finger-bar by a bracket there-
from. To the rear sill or to hangers from the brackets seated thereon is bolted a
wooden bar to which the bottom boards of the platform may be attached, and some-
what in advance of this bar is a parallel board or plank, placed on edge, which
supports the rear guide bar for the platform-apron, the front guide-bar being secured
to the front sill in the usual way. The space between the plank and the rear sill
may be covered by a lid hinged to said plank, and thus form a tool box, and this lid
may at any time be turned up to act as a shield or wind-board for the rear of the
apron.
Overlapping the rear sill of the platform-frame at its outer or stubble end, and at
its upper side, is the rear sill of the elevator-frame, also formed as a hollow bar of
rolled or forged iron rectangular in cross-section, and it may be here stated that all
of the sills or girts hereinafter mentioned are of a similar form and structure except
that the girts will ordinarily be of less diameter than the sills. When a wooden rear
sill is used to the platform-frame it will be of such height as to come up against the
rear elevator sill and be bolted directly thereto, but the tubular sill will be ordinarily
low down and, for a reason presently given, it is often necessary to have the elevator
sill considerably higher, therefore spacing brackets or lifts of metal will be employed
between the two sills where they overlap. Two of these brackets are employed, both
having snugs to embrace the platform-sill and seats for the reception of the elevator-
sill, one being located at the stubble end of the platform-sill and the other at the
inner or grain end of the elevator-sill and bolts passing through the two sills and
brackets complete the joint.
The front-platform-sill, and finger-bar attached thereto, are likewise overlapped by
the front sill of the elevator-frame. The rear elevator sill is in line with the rear
platform-sill, but it is preferred that the front elevator sill shall flare somewhat from
the platform-sill, to which it is attached to give more space for the main wheel and
binding attachment. Spacing brackets or lifts or risers are also interposed between
the front sills where they overlap in order to provide a space for the play of a sway-
bar, when such bar is located beneath the A-frame of the elevator, and this, in the
present construction, is the reason why such brackets are employed between the
rear-sills ahhough the sway-bar does not, or need not, pass between said rear sills,
to wit, to bring the rear-sill into its proper relation with the front sill. It follows
from the oblique arrangement of the front elevator sill that the joints between the

page_text: two, and also between them and the girts, will differ more or less from the others, as
will be directly explained.
The girts or cross-bars may be bolted directly to the front and rear sills, but it is
deemed advisable to interpose metal chairs, which for lightness, for strength, and to
give a certain clasticity to the connection, are made as rectangular frames open in
the center and having upon their upper faces seats to receive the cross-girts, while
other seats at right angles to the foregoing for the rear-sill, and at a suitable angle
for the front sill, saddle and closely embrace said sills. For the innermost cross-
girt, which extends from foot to foot of the inner elevator-struts beneath the A-frame,
chairs are placed in position adjacent to the extreme inner end of the elevator-sills,
and above offsetting extensions of the seats in the spacing brackets, then a securing
bolt is passed through said girt, through the central space of the chair, through the
rear sill and through the bracket-off set, a single bolt clamping all four pieces
together at the front a single bolt passes through the girt, through the chair,
through the inner end of the front inetal sill and through the upper web
of the finger-bar thus completing the fastening at that point. The two girts that
constitute the lateral bars of the wheel-frame and that have secured to them the rack
standards in which the axle is mounted, are likewise attached to the front and rear
metal sills by bolts passing through girts, through the chairs and through the sills
and at the forward end of the inside girt of the pair also through the upper web of
the finger bar, and a fourth girt at the extreme stubble side of the machine is also
secured by a bolt passing through each end of the girt and the chair at that end and
at the end of the sills.
The spacing blocks for the front sills (as well as for the rear sills) may be either
of wood as heretofore used, or of metal, but it is much preferred to make them as
metal brackets which should be hollow or of skeleton outline, to gain lightness so far
as consistent with the requisite strength. The inner spacing block or bracket, or
that adjacent to the front inside elevator-strut is formed with a foot which rests upon
the upper or horizontal flange of the angle-iron finger bar, and it has a snug to come
against the rear of the bar, and may have a second snug to embrace the front edge
thereof. It also has a seat to receive the end of the front elevator-sill, and since this
sill is, in the present structure, oblique to the finger-bar, and it is not found con-
venient to arrange the innermost girt precisely above the intersection of the finger-
bar and sill, the seat is prolonged by means of a flange at the stubble side to come
directly beneath the front chair of said girt, and a bolt is passed through this off set
or prolongation, through the front sill, chair and girt, to unite them. A second bolt
passes through the end of the front sill at the side of said chair through the spacing
block and the horizontal flange of the finger bar at the intersecting points, thus
completing the joint.
The spacing block for the joint between the front-platform-sill or finger-bar and the
inner girt of the wheel-frame is best made as an integral part of the chair when, as
here, the obliquity of the front elevator-sill causes such relation of parts as to permit
it. It is then formed with a foot planting upon the horizontal flange of the finger-
bar, a snug taking over the front edge of said flange, and a forwardly projecting offset
or continuation of the girt-seat, which is undercut to afford a seat for the oblique
sill, this latter running in front of the body of the bracket. The parts are united
by two bolts, one of which passes through the girt, the chair, the bracket or spacer
behind the oblique sill, and the upper flange of the finger-bar, and the other through
the girt, the chair-extension and the oblique sill. These bolts also serve to fasten a
clip for the tongue-pivot upon the upper face of the girt.
In order to support the front outer elevator-strut, the chair which receives the
forward end of the outer bar of the wheel-frame will be formed with an offsetting
seat for the lower end of the strut, and a flange which permits a bolt to be passed
through said strut to firmly secure it. The rear outer elevator-strut may rest upon
the upper face of the rear sill and against the inner side of the outer girt and may
be secured thereto by bolting to a web, which rises from the usual bearing, bracket,
or bridge, connecting the two outside girts at that point, or it may, and preferably

page_text: does, rest upon a seat formed upon said bridge, alongside of which seat the flange
rises from the bridge.
The rack-standards or brackets for the main axle, bolted as before stated to the
lateral bars or girts of the wheel-frame have each one offsetting car at or near the
top, best arranged on the side away from the wheel, through which car pass truss-
rods fixed at their rear ends to said girts above or immediately adjacent to the rear
sill, and at their front ends threaded and passing through lugs from the chairs at the
junction of these girts with the oblique sill, beyond which lugs they receive nuts
whereby they may be tightened to serve their double purpose of bracing the rack
standards and trussing the main-frame.
The front and rear guides for the platform apron are connected near the delivery
end by a cross-beam upon which is fixed a metal bridle having a guide-way for the
play of a block lengthwise of the platform from this block a spindle passes through
the bridge connecting the two arms of the bridle, and a spring coiled around the
spindle and resting at one end against the bridge, and at the other against a collar or
nut secured to the end of the spindle, tends to constantly force or draw the block
toward the divider. Brace-rods secured to said block flare outwards therefrom
towards, and are secured to the bearings for the gudgeons of the idle roller of the
platform-apron, and these bearings slide in ways formed in the divider ends of the
apron guides, thus the idle-roller is constantly forced outward toward the divider,
keeping the apron faut.

Improvements in Harvesters.
A communication from abroad by CYRUS H. MCCORMICK, Junior, of Chicago, in the
County of Cook and State of Illinois, United States of America, Manufacturer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S. of the Agency for Foreign Patent
Solicitors 6, Lord Street, Liverpool, in the County of Lancaster and 323 High
Holborn in the County of Middlesex, Civil 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 base-frame of harvesters, especially those which have an elevator and support
automatic binding apparatus, carries an enormous weight and is subject to great
torsional strain, which tend to twist. it and disorganise the mechanism mounted
upon it.
Heretofore this frame has universally been made of wood, but in one or two
instances, perhaps, that portion immediately beneath the binding apparatus and
constituting the wheel-frame has been of heavy metal castings. Tubular metal bars
have been employed upon the binder-attachment on account of their strength and
lightness, to afford means for the adjustable attachment to the elevator-frame, and for
this purpose have been found eminently suitable, their cylindrical shape offering no
objection, but rather facilitating such adjustable attachment. But this very cylindrical
outline renders them unsuitable for use in a base-frame to which other and heavier
framework is to be applied, and upon which tremendous torsional strain will come,
since the fastening bolts will receive no assistance and will be in no wise braced by
this shape, but must themselves alone sustain the entire strain.
In the present invention it is proposed to replace the base-sills or base-sills and
girts of the harvester-frame by sills and girts of tubular metal, square or rectangular,
or practically so, in cross-section, which will afford the same facility for attachment
between themselves, and of other parts of the frame-work, and the same or increased
strength of joint at such points of attachment as do the square wooden beams and
timbers heretofore used for the purpose, and will therefore involve no further
reorganization of the superposed parts.
Since the greatest weight and greatest strain is in the immediate vicinity of the
main-wheel, which is located under the elevator, these tubular bars of rectangular
cross-section may be beneficially employed in the base-frame of the elevator alone,
this also including the wheel-frame, leaving the front and rear sills of the platform-
frames of wood, as heretofore, overlapping and bolted to the front and rear sills of the
elevator-frame, but it is preferred to carry the tubular construction into the rear
platform-sill and divider-girt at least, and the invention will be thus described herein.
A further feature of the invention relates to the tightener for the platform-apron
and more particularly to certain improvements upon the tightener made the subject of

page_text: -
letters patent of the Kingdom of Great Britain, No. 7855, dated June 29, 1885, as
will presently be explained.

said platform and the divider;
Figures 19 to 23, enlarged details of the apron-tightener, and
Figure 24, an elevation of the divider from the grain side.
Now proceeding to describe the invention, the front sill A of the platform-frame is,
or may be, a bar of wood, as usual, forming a back to an angle-iron finger-bar A¹,
which has its horizontal web a uppermost and flush with the upper edge of said sill
and, being bolted thereto at intervals, strengthens and braces it. The rear sill B, as
already intimated, it is preferred to construct as a tubular bar of rolled or forged iron,
rectangular in cross section, occupying the place of the customary wooden rear
platform-sill. At its outer or grain end this sill receives a metal bracket B3 having
snugs at its foot whereby it saddles and closely embraces the upper side of the sill,
and at its top a slightly oblique seat for the rear end of the divider-girt C, which
likewise is a rectangular tubular bar and is secured at this point by a bolt c passing
through the bracket and rear sill, thence extends forwardly past the finger-bar and to
the point of the divider, being suitably supported adjacent to the finger-bar by a bracket
therefrom. To the inner side of the tubular rear sill or to brackets c¹ seated thereon
is bolted a wooden bar C¹ to which the bottom boards of the platform may be attached,
and somewhat in advance of this bar is a parallel board or plank C² placed on edge
which supports the rear guide-bar e² for the platform-apron, the front guide-bar c³
being secured to the front sill in the usual way. The space between the plank and the
rear sill may be covered by a lid Chinged to said plank, and thus form a tool-box,
and this lid may at any time be turned up to act up as a shield or wind-board for the
rear of the apron.
Overlapping the rear sill of the platform-frame at its outer or stubble end, and on
its upper side, is the rear sill D of the elevator-frame, also formed as a hollow bar of
rolled or forged iron rectangular in cross-section, and it may be here stated that all of
the sills or girts hereinafter mentioned are of similar form and structure, except that
the girts will ordinarily be of less diameter than the sills.
When a wooden rear sill is used to the platform-frame it will be of such height as
to come up against the rear elevator-sill and be bolted directly thereto, but the tubular
sill will be ordinarily low down, and for a reason presently given it is often necessary
to have the elevator sill considerably higher, therefore spacing brackets or lifts D¹ of
metal will be employed between the two sills where they overlap. Two of these
brackets are employed, both having snugs d to embrace the platform sill and seats d¹
for the reception of the elevator-sill, one being located at the stubble end of the
platform-sill and the other at the inner or grain end of the elevator-sill, and bolts d²
passing through the two sills and brackets complete the joint. The brackets are also
offset at one side to form prolongations d³ of the seats for the elevator-sill, beneath the
inner cross-girts of the elevator-frame, that said girts may be bolted through the sill
to such offsets, as presently explained.
.
The front platform-sill, and finger-bar attached thereto, are likewise overlapped by
a tubular bar E, of rolled or forged iron, also rectangular in cross-section, which
extends therefrom a sufficient distance to constitute the front sill of the elevator frame.

page_text: The rear elevator-sill is in line with the rear platform-sill, but it is preferred that the
front elevator-sill shall flare somewhat from the platform-sill, to which it is attached,
to give inore space for the main wheel and binding attachment. Spacing brackets or
lifts or risers E' are interposed between the two front sills where they overlap, in
order to provide a space for the play of the sway-bar, where such bar is located
beneath the A-frame of the elevator, and this, in the present construction, is the
reason why such brackets are employed between the rear sills although the sway-bar
does not, or need not, pass between said, rear sills; to wit'; to bring the rear sill into
its proper relation with the front sill. It follows from the oblique arrangement of the
front elevator-sill that the joints between the two, and also between them and the
girts, will differ more or less from the others, as will be directly explained.
The girts or cross bars may be bolted directly to the front and rear sills, but it is
deemed advisable to interpose metal chairs F, which, for lightness for strength, and to
give a certain elasticity to the connection, are made as rectangular frames open in the
centre and having upon their upper faces seats to receive the cross-girts, while other
seats at right angles to the foregoing for the rear-sill, and at a suitable angle for the
front sill, saddle and closely embrace said sills. For the innermost cross-girt G which
extends from foot to foot of the inner elevator-struts beneath the A-frame, chairs are
placed in position adjacent to the extreme inner end of the elevator-sills, and above
offsetting extensions of the seats in the spacing brackets, both at front and at rear, as
already partly explained, then a securing bolt is passed through said girt, through the
central space of the chair, through the rear sill, and through the bracket-offset ;
a single bolt clamping all four pieces together; at the front a single bolt passes through
the girt, through the chair, through the inner end of the front metal sill, and through
the upper web of the finger-bar, thus completing the fastening at that point. The two
girts H, H, constituting the lateral bars of the wheel-frame and that have secured to
them the rack-standards h, h¹, in which the axle is mounted, are likewise attached to
the front and rear metal sills by bolts passing through the girts, through the chairs
and through the sills, and at the forward end of the inside girt of the pair, also through
the upper web of the finger-bar and the spacing-bracket, and a fourth girt I at the
extreme stubble side of the machine is also secured by a bolt passing through cach
end of the girt and the chair at that end, and at the end of the sills.
The spacing blocks for the front sills, (as well as for the rear sills) may be either of
wood as heretofore used, or of metal, but it is much preferred to make them as metal
brackets which should be hollow or of skeleton outline, to gain lightness so far as
consistent with the requisite strength. The inner spacing block, or bracket, or that
adjacent to the front inside elevator-strut is formed with a foot i which rests upon the
upper or horizontal flange of the angle-iron finger-bar, and it has a snug to come
against the rear of the bar, and may have a second snug to embrace the front edge
thereof. It also has a seat to receive the end of the front elevator-sill, and since this
sill is, in the present structure, oblique to the finger-bar, and it is not found convenient
to arrange the innermost girt precisely above the intersection of the finger-bar and
sill, the seat is prolonged by means of a flange 3 at the stubble side to come directly
beneath the front chair of said girt, and a bolt is passed through this offset or
prolongation, through the front sill, chair and girt, to unite them as already explained.
A second bolt passes through the end of the front sill at the side of said chair, through
the spacing block and the horizontal flange of the finger-bar, at the intersecting points,
thus completing the joint.
The spacing block for the joint between the front platform-sill or finger-bar and the
inner girt H of the wheel-frame is best made as an integral part of the chair F when,
as here the obliquity of the front elevator-sill causes such relation of parts as. to
permit. It is then formed with a foot planting upon the horizontal flange of the
finger-bar,
a snug
taking over the front edge of said flange, and a forwardly
projecting offset or continuation of the girt-scat, which is undercut to afford a scati
for the oblique sill, this latter running in front of the body of the bracket. The parts
are united by two bolts one of which passes through the girt, the chair, the bracket or

page_text: spacer behind the oblique sill and the upper flange of the finger-bar, and the other
through the girt, the chair-extension and the oblique sill. It is also provided in the
angle behind the oblique sill and beneath the girt with a bearing 8, for the draft-pole I
which is secured therein by means of curved hounds, as shown.
In order to support the front outer elevator-strui. K the chair which receives the
forward end of the outer bar of the wheel-frame will be formed with an offsetting
seat, for the lower end of the strut, and a flange k¹ which permits a bolt to be passed
through said strut to firmly secure it. The outer elevator-strut L
may rest upon the
upper face of the rear sill and against the inner side of the outer girt and may be
secured thereto by bolting to a web which rises from the usual bearing, bracket or
bridge I connecting the two outside girts at that point or it may, and preferably does,
rest upon a seat formed upon said bridge alongside of which seat the flange rises from
the bridge.
The rack-standards or bridle-brackets for the main axle, bolted as before stated to
the lateral bars or girts of the wheel-frame, have each one offsetting ear mat or near
the top, best arranged on the side away from the wheel, through which ears pass truss-
rods M, fixed at their rear ends to said girts above or immediately adjacent to the rear
sill, and at their front ends threaded and passing through lugs from the chairs at
the junction of these girts with the oblique sill, beyond which lugs they receive nuts m²
whereby they may be tightened to serve their double purpose of bracing the rack-
standards and trussing the main-frame.
The front and rear guides for the platform-apron are connected near the delivery
end by a cross beam N upon which is fixed a metal bridle N having guide-ways n for
the play of a block N2 lengthwise of the platform; from this block a spindle a passes
through the bridge connecting the two arms of the bridle, and a spring n² coiled
round the spindle and resting at one end against the bridge, and at the other against a
collar or nut n³ secured to the end of the spindle, tends to constantly force or draw
the block towards the divider. Brace-rods N³ rigidly secured to said block flare
outwards therefrom towards, and are rigidly secured to, the bearing boxes for the
gudgeons of the idle-roller of the platform-apron, and these bearings slide in
ways formed in the divider ends of the apron guides, thus the idle roller is
constantly forced outward towards the divider, keeping the apron taut.
The inner or non-adjustable roller O for the platform-apron has its rear gudgeon o
supported in a long sleeve bearing o' that extends from the vertical plank C
rearwardly through the inner elevator-strut or board and is there secured by means
of an integral bracket-plate or flange 01 seated upon, embracing and bolted to the
metal rear sill and also independently bolted to the foot of said elevator-strut and
serving to secure it to said sill. Outside of the bracket it is expected that the
gudgeon will receive a sprocket-wheel or pinion whereby it may be driven.
The rear elevator-struts are further braced by means of an angle iron bracket P,
one arm of which rises vertically from the foot of the inner strut after being suitably
bolted thereto and to the casting which secures it to the rear sill, then extends
horizontally a short distance towards the stubble side in order to receive and support
the seat plank P1, then passing at a slight upward incline towards said stubble side
is again bolted to the inner strut and finally to the outer strut, making a very light
and strong brace, and subserving two functions.
As practically the whole platform-frame is of metal it becomes necessary to modify
the means whereby the divider and the grain-wheel are supported. The divider-girt
it has already been explained, extends obliquely forward, and as usual, is in a horizontal
position. It is continued beyond the finger-bar, to practically the extreme point of
the divider, where a shoe Q is bolted to it, from which the inclined divider-board Q
extends upwardly, outwardly and rearwardly. A second or false shoe Q is bolted to
the divider-girt somewhat to the rear of the divider shoe, and is formed with a socket y
into which the point of the outer guard-finger 7 enters, partly to insure a clean
division of the grain and partly to brace the finger-bar and divider-girt.
A metal upright R is bolted to the divider-girt immediately above the finger-bar

page_text: and has an offset sitting over said girt and secured by a cross-bolt to make the
connection more certain and beneath it is bent laterally and formed with a seat which
rests upon said finger-bar and a flange depending along the vertical flange of said
bar, and embracing it by a snug at the bottom and secured to said flange by
horizontal bolts while at its upper end it bends obliquely as at ³ so as to be secured to
and aid in supporting the divider-board.
The grain-wheel S turns upon a stub-axle s projecting from a traveller s sliding in
ways in a rack-standard S1 and adjusted by means of a lever S³ and a dog controlled
thereby. Such rack-standard and the accompanying means of adjustment have been
used heretofore upon machines introduced into England by the McCormick Harvesting
Machine Company, with these exceptions, that the standard is now bolted to the
tubular divider-girt, being provided with an oblique shoes that complements the
obliquity of the divider-girt so as to bring the grain wheel parallel with the line of
travel, this shoe having snugs which sit over and grasp said girt and that the
fastening being completed by bolts, it extends up and is deflected obliquely outward at
the top as at so as to be bolted to the rear end of the divider-board and further
secures it.
2
To protect the grain-wheel from ordinary injuries a fender bar Tis bolted at t to
the grain end of the rear platform-sill, then is bent and carried forward outside of said
sill until immediately in front of the wheel it reaches the just mentioned upright which
connects the finger-bar, divider-girt and grain-board, when it passes through lateral
snugs formed integrally with the foot of said upright, thence is bent obliquely
inward and upward until it reaches the front end of the divider-girt, to which it is
secured preferably by the same bolt that unites the latter to the divider-shoe.
Having now particularly described and ascertained the nature of the said invention'
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
1. The combination, to form a harvester base-frame of tubular metal rear and front
sills rectangular in cross-section, and metal girts uniting said rear and front sills.
2. The combination, to form a harvester base-frame of metal rear and front sills,
and metal girts uniting said rear and front sills, both sills and girts being tubular and
rectangular in cross-section.
3. The combination substantially as hereinbefore set forth, to form a harvester-
frame of metal rear and front sills, metal girts, extending from the rear sill to the
