Improvements in Grading and Ditching Machines.
I, WILLIAM JOSEPH EDWARDS, of the City of Chicago, in the County of Cook
and State of Illinois, United States of America, Gentleman 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 my invention, generally stated, is to increase the general efficiency
and serviceability of a grading and ditching machine, or "grader and ditching-
machine," as I prefer to term it.
My invention consists in matters hereinafter set forth and particularly specified in
the claims.
In the accompanying drawings,
Figure 1 represents in side elevation the main portion of a grader and ditcher
embodying my invention, the side illustrated being the one at which the plan is
arranged for operation, and hence termed either the "receiving" or "plow" side of
the machine in contradistinction to the opposite delivery side from which the plowed-
up earth is to be delivered from an elevator.
Figure 2 is a detail representing a section taken through the caster-wheel standard
on the line 2-2, Figure 1, and illustrating in plan the caster-wheel scraper and its
support, with the outer end portions of the arins upon which the caster-wheel is
journaled broken away.
Figure 3 is a detail representing a vertical section through the caster-wheel scraper
and its support on the line 3-3, Figure 2.
Figure 4 represents in side elevation the delivery side of the main portion of the
grader and ditcher, the parts thereof above the platform being removed for con-
venience of illustration. The near rear supporting-wheel is also removed in this view.
Figure 5 represents in side elevation a portion of the plow-beam with a bracket
attached thereto and adapted for establishing jointed or flexible connection between the
plow-beam and a swinging controlling-bar, G, which latter is shown in cross-section.
Figure 6 represents a vertica! section taken transversely through the plow-beam on
the line 6-6, Figure 5, and illustrates a portion of the edge of bar G, which,
when said bar is in place, as in Figure 4, will be its rear edge relatively to the front
and rear ends of the ditcher and grader.
Figure 7 represents in perspective the end portion of the bar G that is included
in Figure 6, the slotted plate 52, shown secured to the rear edge of the bar in said
Figure 6, being, however, omitted in Figure 7, in order to more clearly illustrate a
kerf or recess formed in the end of the bar.
Figure 8 represents a vertical section taken transversely through the machine on
the line 8-8, Figure 1, and looking toward the rear of the machine.
Figure 9 is a detail representing an adjustable hinged connection between the
plow-beam and its rear controlling-bar, E, which said connection is adapted to take
the place of the adjustable hinged connection shown in Figure 8. In said Figure 9
the plow-beam is shown in cross-section, as in Figure 1, and a portion of the con-
trolling-bar represented.
Figure 10 shows a portion of the elevator-belt understood to be passing around the
belt-driving drum or roller at the delivery end of the elevator, and represents, means
for connecting the meeting ends of two adjacent belt-sections.
Figures 10 and 10° are details illustrating the belt-fastening.
Figure 11 represents a vertical section taken transversely through the machine on
the line 11-11, Figure 1, and looking toward the front end of the machine.
Figure 12 is a detail representing on a somewhat larger scale the slotted end of
the bar 33 shown in Figure 11.

page_text: gure to represents in perspective a socket-piece adapted as a support for one
end of the rear-beam-controlling bar E, and designed to have a sliding pivotal con-
nection with the slotted end portion of the fixed har 33.
Figure 14 may be regarded as a sectional plan taken on a substantially horizontal
plane just below the level of the main platform-frame or just below the main longi-
tudinal sills of the body-frame, the design being to represent in top plan the principal
portions of the machine below the sills or platform. In this view the delivery-end
portion of the elevator is, for convenience of illustration, broken away, as is also the
forward end portion of the plow-beam.
Figure 15 principally represents, partly in top plan and partly in horizontal section,
the clutch and clutch-actuating device, whereby power can be applied for operating a
sprocket herein employed for driving a link-belt, which in turn is to operate a belt-
roller at the delivery end of the elevator. This view indicates in full lines the
shifting-clutch member closed or in clutch and in dotted lines said member open or
out of clutch.
Figure 16 is a face view of the clutch member 152, which is toothed to provide the
sprocket.
Figure 17 is a like view of the shifting-clutch member.
Figure 18 represents in perspective one of a pair of boxes herein employed as
journal-supports for a belt-roller at the receiving end of the elevator, said box being
shown in top plan, Figure 14.
Figure 19 represents a longitudinal section taken centrally through said box.
Figure 20 represents, on a somewhat larger scale, a section taken through the rear
wheels and boxes for the rear axle on a vertical plane coincident with the axis of the
axle, which latter is, however, for clearness of illustration, not shown in section.
This view also represents the pawl-and-ratchet devices on the rear axle.

in Figure 20, and represents the internal set of ratchet-teeth.
Figure 22 is a like view of the cap 143, provided with pawls for engaging the
ratchet-teeth of the aforesaid hub, and shown in Figure 20 secured to the hub of one
of the supporting-wheels.
Figure 23 represents a top plan view of the lower half of one of the boxes for the
axle of Figure 20, said lower half being exposed by removing the upper half, which
in the next succeeding Figure is shown applied.
Figure 24 represents a section taken through one. of said axle-boxes on the
line 24-24, Figure 23, the upper and lower halves or parts of the box being fitted
together.
Figure 25 represents in perspective two sections of the elevator coupled together
and secured in alignment, said sections being the one at the delivery end and the next
preceding section.
Figure 26 represents a pair of the guide-guards or side-boards, F, shown in other
views arranged over and parallel with the length of the elevator-belt, this particular
view serving to more clearly represent a lock-joint between two abutting ends of such
sides or guards and one of their supporting attachments or arms, 82.
Figure 27 represents the abutting ends of the two guards or side-boards of the
preceding Figure and shows the locking device on a somewhat larger scale.
Figure 28 represents in perspective the two elevator-sections of Figure 25 in
position to separate their opposing ends, the object of this view being to illustrate a
construction of break-joint whereby the elevator-sections can be detached from one
another or connected together and brought into alignment, as may be required.
Figure 29 represents one of the connecting-hooks 111 of the preceding Figure.
Figure 30 is a top plan view of several of the elevator-sections, secured in align-
ment and illustrates a belt-driving roller arranged at the delivery end of the elevator.
This view also includes a portion of the link-belt and shows in horizontal section a
.shield, M, herein employed for covering the sprocket upon one of the driving-roller's
journals.

page_text: Figure 31 is a longitudinal central section through Figure 30 on line 31-31.
Figure 32 represents the abutting end portions of a couple of the longitudinal side
bars of elevator-sections of the preceding Figure and illustrates a form of coupling
which, when found desirable, can be employed in place of the hooks of Figure 28.
Figure 33 represents in perspective the coupling-plate of the preceding Figure.
Figure 34 represents, on a larger scale, a section taken longitudinally through the
belt-driving roller on line 34-34, Figure 30.
Figure 35 is a section taken transversely through the elevator on line 35-35,
Figure 30.
Figure 36 represents a section taken on a vertical plane through the forward
supporting-wheels, the boxes for their axle, and front bolster, the plane of this
section being coincident with the axis of the axle, which, however, is shown in
elevation.
Figure 37 represents an end view of the axle and front bolster of the preceding
Figure with the wheel removed, and shows a portion of the half-circle or fifth-wheel
and certain adjuncts, including a portion of the middle longitudinal sill, 3, of the
platform or main frame of the machine.
Figure 38 is a detail representing in rear elevation certain bearings for the king-
bolt of the preceding Figure.
Figure 39 represents a vertical section taken through the front axle on the
line 39-39, Figure 36, and shows in side elevation, on a somewhat larger scale, the
king-bolt and its bearings.
The principal portion of the structure herein illustrated comprises a horizontal
rectangular body or platform frame, A, adapted at certain points for operatives to
stand upon, and supported upon front and rear bolsters, which are in turn supported
from the front and rear wheeled axles.
The body or platform frame may include the two longitudinally-arranged side
sills, 1 and 2, and a middle longitudinal sill, 3, secured at their ends to the front and
rear bolsters and at points intermediate of the two bolsters connected together by two
or more lower cross-sills, 4 and 5, and a corresponding pair of upper cross-sills, 6 and 7.
B indicates the plow-beam suspended alongside the machine and carrying a suitable
plow, C.
The plow-standard 8 is pivotally attached to the beam by a pivot-bolt, 9, having its
bearings in plates secured to opposite sides of the beam. By thus pivotally hanging
the plow from the beam the plow can be swung about its pivotal support in order to
determine the angle of penetration. As a means for securing the plow in such
adjustment, it is provided with a rearwardly-arranged and upwardly-extending arm
or bar, 10, attached at its lower end to the plow and at its upper end adjustably con-
nected with a segment-plate, 11, Figures 1 and 4, which is secured to the beam and
provided with a series of bolt-holes for such pin or bolt as may be employed for
connecting the arm 10 with the segment-plate. The arm 10, while serving to permit
the plow to be set at a desired angle, also serves as a brace which will effectively resist
all ordinary strain to which the plow may be subjected by the resistance opposed to
progress. Should, however, the plow meet with a sudden and impassable resistance
or barrier during the advancement of the machine, the pin or bolt by which arm 10 is
attached to the segment-plate will be cut off by the arm and the plow permitted to
yield until the machine can be stopped, in place of a general breakage of either, the
plow or its connection with the beam through the pivoted standard 8. The plow and
its standard are, therefore, to be made of considerable strength, and to such end the
channel-iron standard subserves a useful purpose. As a further simple means for
bracing the plow, the mold-board is connected with the channel-iron plow-standard by
a short bent brace-rod, 12, Figure 14, bolted both to the mold-board and to the plow-
standard.
The plow can be placed under the control of an operator standing up on a platform
on the body-frame A, to which end the forward end of the plow-beam can be quickly
raised or lowered to give to it the required running depth by means of a rope or
chain, 13, Figure 1, attached to the forward end portion of the plow-beam and carried

page_text: up over a pulley 14, to a short rotary drum or shaft, 15, which is mounted in a
bearing, 16, Figure 8, above the main body-frame and provided with a hand-wheel, 17,
whereby the operator can raise and lower the forward end of the plow-beam at will.
The somewhat elongated bearing 16 is herein shown as a support for the end portion
of shaft 15 next adjacent to the hand-wheel, and as a means for further steadying
the opposite end of the shaft said end is mounted in a short bearing, 18, at the upper
end of an inclined brace-rod, 19, which inclines downwardly toward the forward end
of the machine, and is at its lower end secured to the side sill, 1, whereby it is arranged
in position to best withstand the pull of chain 13 on the shaft 15. The rear end of
the plow-beam can also be raised and lowered at will by an attendant standing upon
the machine, the chain 20 for this purpose being at one end connected with the rear
portion of the plow-beam and at its remaining end attached to a rotary drum or
shaft, 21, which is arranged longitudinally with relation to the length of the machine
and mounted in bearings on the prongs or forks of a double-armed bearing-piece, 22.
The shaft 21 is provided with a suitable hand-wheel, 23, and the double-armed
bearing-piece 22 is secured upon a standard, 24, rising from the main body-frame
and suitably secured to a convenient portion thereof-such, for example, as the side
sill, 1. The bearing 16 for the rotary winding-shaft 15 is formed upon one of the
bearings for the winding-shaft 21, in which way the standard 24 also sustains a bearing
for the winding-shaft 15, that is arranged transversely to the length of the machine,
while by the presence of rod 19 the provision of an additional standard is rendered
unnecessary. Suitable locking devices are employed for locking the aforesaid hand-
wheels as soon as the ends of the plow-beam have been raised or lowered to the
required extent.
The standard or bracket 25, arranged at one of the forward corners of the main
body frame as a support for maintaining pulley 14 at the desired elevation, is simply
provided at its base with two arms or legs, one of which is secured to the side sill, 1,
and the other secured to the front bolster of the running-gear.
The plow-beam carries at a point in advance of the plow a rolling colter, herein
shown connected with the plow-beam. The plow-beam is capable of a limited end
play or movement, the extent of its forward movement being governed by a chain, 26,
Figure 1, attached to the beam at a point preferably in advance of the colter. This
chain can be simply caught at some desired point along the upper portion of its length
upon a hook, 27, secured to the side sill, 1, at a point somewhat to the rear of the point of
attachment of the chain to the beam, so as to extend back in opposition to the draft upon
the plow-beam. In this way the extent to which the plow-beam may be drawn
forward can be determined by the length of chain between the plow-beam and the
point at which the chain is attached to the main body-frame of the machine.
The rear end of the plow-beam is flexibly or pivotally connected with a bar, E,
which is arranged transversely, or substantially so, to the plow-beam and capable of
several distinctive movements-namely, a horizontal swing or vibratory motion in a
horizontal or substantially horizontal plane, a vertical swing or vibratory motion in a
vertical or substantially vertical plane, and an end movement or longitudinal recipro-
catory action. As a means for permitting such movements on the part of bar E, it is
at one end connected with the plow-beam by a hinge or pivotal joint and at its other
end pivotally attached by a vertical pivot bolt or pin, 28, Figure 14, to a bearing, 29;
which is supported so as to be capable of both a sliding movement in a direction trans-
versely with relation to the plow-beam and a rotary play about a horizontal axis.
This bearing 29 preferably consists of a socket-piece adapted to receive the bar E and
provided with bolt-holes in its top and bottom sides for the pin or bolt 28, one of said
bolt-holes, 30, being shown in Figure 13. Said socket-piece is also provided with a
laterally-projecting stud or pivot, 31, engaging in a guide-slot, 32, which can be
formed in any suitable bearing piece or fixture, but which is herein shown formed in
the lower portion of an inclined brace-bar, 33, that is at its lower end secured to any
suitable fixture-such, for example, as a frame-bar, 34, attached to and depending
from the side sill, 2-and at its upper end secured to the middle longitudinal sill, 3,
of the body-frame, as shown; for example, in Figure 11. The pendent support 34 is

page_text: arranged in rear of the elevator--that is to say; between the elevator and the rear
axle whereby the bar E will be arranged at a point where it may have the desired
extent of horizontal swing without interfering with the elevator.
The bar E is capable of a limited extent of lateral vibratory play in the socket-
piece it being seen that a slight vibratory motion of the bar in such socket piece or
bearing will permit a much greater extent of swing on the part of its end that is con-
nected with the plow-beam, and that such swing is intended to be and in practice is
ample for all practical purposes. The bar E is also provided with a line of vertical
bolt-holes, as indicated at 35, Figure 14, whereby an end adjustment of this freely-
swinging and longitudinally reciprocatory bar can be readily effected by a transfer of
the pin 28 from one to another of such bolt-holes.
The end adjustment of bar E is to be made with reference to the position of, the
plow relatively to the lower receiving end of the elevator F, having an endless apron
or belt upon which the soil is received from the plow and carried up and over to one
side of the machine, it being understood that for different soils it is desirable that the
plow shall work more or less closely to the receiving end of the elevator, the working
position of the plow in this respect being determined by the character of the soil
delivered from the plow to the elevator. The end or longitudinal play of the bar E.
allows the plow to line itself to different soils and to dodge to one side or the other to
avoid obstructions or adapt itself to the character of the ground, which is frequently
such as to render it difficult for the plow as a whole to pursue an exact rectilineal
course. This play on the part of the plow is permitted by reason of the sliding pivotal
connection between the bar E and a guideway, such as set forth, which said connection
also permits the rise and fall of the rear end of the plow-beam. The horizontal
vibratory swing of bar E permits an end movement on the part of the plow-beam,
whereby the plow can be made to work farther forward or more to the rear relatively
to the receiving end of the elevator, it being also desirable to position the plow in
this respect with reference to its delivery of different soils to the elevator. The limit
of the forward end movement of the plow-beam can be determined by the chain 26,
while the limit of its end movement in a rearward direction can be determind by an
adjustment in length of the draft-chain hereinafter described.
The hinge or pivotal connection between the vibratory and reciprocating bar E
and the plow-beam involves an adjustable bearing, whereby the plow can be tilted
to one side with reference to the cut to be made-as, for example, in cutting
sod it is desirable to tilt the plow to one side, so as to make a clean cut instead
of a tearing cut. In several of the Figures this adjustable hinge-connection
between bar E and the plow-beam is similar to a connection between the rear
end of the plow-beam and a transversely-arranged bar having a sliding pivotal
connection with a supporting bracket or hanger, such connection (see, for
example, Figure 8) consisting of a hinge-pintle plate or leaf, 36, provided with
one or more curved slots for bolts, by which it is adjustably attached to bar E
and connected with the plow-beam B. by a pintle or pivot-bolt 37, having its bearings
in a bracket, 38, secured to the plow-beam and at its ends extending through eyes or
pintle-sockets on the plate 36. A simplified adjustable hinge-connection between.the
bar E and plow-beam is, however, shown in Figure 9, wherein the connection
comprises a stout nietal strap or flat bar, 39, secured to the lower edge of bar E and
projecting to some extent from the end of the bar, and an inclined rod or bar, 40,
having at its lower end a slot, 41, for a bolt, 42, by which it can be adjustably secured
to the bar E. These bars 39 and 40 are at their ends next to the plow-beam provided
with eyes for a pivot-bolt, 43, which can be attached to the beam or any suitable
bracket thereon-such, for example, as to the bracket 38, hereinbefore described. In
this way, by adjusting the rod or bar 40 in its connection with bar E, the plow can
be tilted to one side to the required extent.
The forwardly-arranged swinging bar G, which, like the bar E, is employed to
control the movements of the plow, is arranged transversely with relation to the
plow-beam and attached thereto by a flexible or hinged connection. The-bar: G. is
capable of both a vertical and. a horizontal swing or vibratory, motion, and is further

page_text: .
one
susceptible of an end or longitudinal adjustment. As a means for permitting such
movements on the part of the bar G, it is at one end flexibly connected with the beam
and at its opposite end pivotally attached to a support, 44, (see, for example,
Figure 4), by a vertical pivot pin or bolt, 45. This pivot permits a horizontal swing
on the part of the bar G in correspondence with a similar swing on the part of the
rearward controlling-bar, E, so as to allow an end movement of the plow-
beam, for purposes hereinbefore mentioned. This pivotal .connection between
end of the bar G and the support 44, or other suitable bearing for
such end of the bar, permits the latter to swing in a vertical or substantially
vertical plane in unison with such rise and fall of either the forward end of the
plow-beam or of the entire plow-beam, as the case may be, it being understood
that in either instance the greatest extent of rise and fall that may be incurred by
the end of bar G that is flexibly attached to the plow-beam will necessitate so slight
a motion on the part of the pivotally-supported end of the swinging bar that
the vertical pivot 45, simply inserted through a hole of proper diameter in the
swinging bar, will, for all practical purposes, permit such end tilt or vertical swing
on the part of said bar.
The bars E and G, being pivotally supported independently of one another, may
therefore, so far as the rise and fall of the plow and plow-beam is concerned, either
tilt or swing in unison or otherwise, accordingly as the beam may either rise and fall
equally at both ends or tilt, as the case may be. The bar G is also adjustable end wise,
for which purpose it is provided with a series of bolt-holes, 46, Figure 14, for
the removable pivot 45, in which way the bar can be adjusted longitudinally by
selecting one or another of such holes for the pivot. When the plow is tipped to
one side for cutting sod by adjusting the hinged connection between bar E and the
plow-beam, as herein before set forth, the bar G and also the bar E can be adjusted
in order to shift the plow-beam laterally and to an extent to prevent the plow from
running into or working in too close proximity to the receiving end of the elevator.
On the other hand, these two bars can be adjusted endwise, so as to shift the plow-
beam laterally, and thereby vary the distance between the plow and the receiving
end of the elevator whether the plow be tilted to one side or not. Thus, for
plowing up and delivering loose soil to the elevator, the plow should work closer to
the elevator than in plowing and delivering clay or other soil having more body and
permitting the plow to make a wider furrow.
The draft is from the pole or middle point of the front axle, and is attained by
extending the draft-chain H back from such point and attaching it to the forward
controlling-bar, G. In this way, in place of drawing obliquely from one corner of
the machine in a direction tending to "diamond the main body-frame, the draft is
in a direction coincident with the length of the machine and midway of its
longitudinal sides, whereby all pull upon the machine tends to "square" its frame,
since such pull is in a direction with the longitudinal sills of the frame and
transverse to its cross-sills. This adds materially to the life or period of usefulness
of the machine and avoids frequent repairs.
The draft-chain is made adjustable in length in any suitable way-for example,
by an adjustable link or connection, 47, interposed along its length, as in Figure 14,
whereby the limit of the rearward swing of the bar G can be varied in order to
cause the plow to work more or less forward or back relatively to the receiving end
of the elevator. In this connection provision is made for shifting the pivotal end
of bar G to the front or rear, so as to permit the bodily lateral adjustment of the
bar either forward or back. By thus limiting the extent of swing to the rear on the
part of bar G, by positioning the pivotally-supported end of said bar and properly
adjusting the length of the draw-chain, the plow can be permitted to work farther
forward or back relatively to the receiving end of the elevator and with reference to
the character of the soil, it being desirable to work the plow farther back relatively
to the receiving end of the elevator for loose soil than for clay or like earth. This
adjustment of the pivotally-supported end of the bar G can be readily attained by
providing for its removable pin or pivot bolt 45 a series of bolt-holes in the

page_text: support 44, a line of such holes, 48, being shown on the upper portion of such support
in Figure 14.
In order that the draft upon the plow may be in a line coincident with the plow-
beam and from a point in front of the mold-board, the hinge or flexible connection
between the plow-beam and the bar G is made at a point to one side of the plow-
beam and in front of the mold-board of the plow. In this way, the draft through
the draft-chain H being on the bar G, and the connection between such bar and the
plow-beam being in front of the mold-board, the draft will act as a landside or
greatly relieve the landside of the plow. This arrangement also serves to keep the
plow-beam from crowding against or running into either the side of the machine or
such one of the front wheels as the plow-beam may be extended alongside of, and
further serves to maintain a caster-wheel, I, at the forward end of the plow-beam
at all times in proper position relatively to the surface of the ground over which it is
travelling. Said feature is also particularly serviceable in positioning the caster-
wheel to run up banks or furrows or run along inclined hanks at a time in the process
of road-making when such banks incline downwardly toward the lowest level traversed
by the main supporting front wheel that is opposite the caster-wheel, and also
prevents the caster-wheel from getting under or running under such main front
supporting wheel.
As an efficient connection between the bar G and the plow-beam, the latter is
provided with a bracket which inclines outwardly from the plow-beam and is provided
at a point properly remote from the plow-beam with a horizontal pivot, 49. (Best
shown in Figures 5 and 6.) The bar G is at its end nearest the plow-beam provided
with a horizontally-cut kerf or recess, 50), Figure 7, for the reception of said horizontal
pivot, which extends through said recess in a direction transversely to the bar G and
parallel with the plow-beam.
To the front edge of bar G is secured a plate, 51, which, if preferred, may extend
the entire length of the bar to strengthen the same, and in said plate is formed a
pivot-hole arranged opposite the recess 5) in the bar and adapted for the reception
of the pivot 49 at a point adjacent to what may be termed the "forward" end of the
pivot relatively to the machine in which it is employed.
To the rear edge of bar G is secured a plate, 52, Figure 6, which is extended
alongside the recess in the bar and opposite such recess provided with a longitudinal
slot, 53, for the passage of the rear end portion of the pivot. The hanger is provided
with two pivot-bearings, respectively opposite the front and rear edges of the bar, and
adapted for supporting the front and rear ends of the pivot, a simple construction of
bracket-support for the pivot being an inclined arm or bar, 54, secured at its upper
end to the plow-beam and at its lower end provided with a bearing, 55, for one end
of the pivot, and a somewhat similarly secured and arranged inclined ari, 56, provided
at its lower end with a bearing, 57, for the forward end of the pivot, and having at a
point above such bearing a diverging brace-arm, 58, that is secured to the plow-beam.
It is, however, herein understood that other forms or constructions of hangers or
brackets could be employed for a like purpose.
The foregoing construction of connection between the bar G and the plow-beam
adapts it to the movements of the bar and plow-beam, it being seen that during an
end movement of the plow-beam and a horizontal swing on the part of bar G the arc
traversed by the end of such bar next adjacent to the plow-beam will cause the rear
end portion of the pivot to be drawn toward one or the other of the ends of slot 53,
according to the direction in which the plow-beam and bar G are moved, and also that
such connection affords a joint which permits the beam to be inclined to one side in
tilting the plow.
From the foregoing it will be seen that the devices herein illustrated for supporting
the independently-arranged front and rear plow-beam-controlling bars E and G
operate substantially as universal joints, both adjustable in position upon fixtures or
supports on the main frame of the machine, the joint for the rear bar, E, being also a
sliding joint to permit lateral play or automatic side movement on the part of the
rear end of the plow-beam; also, that by means of such joints a ready end adjustment

page_text: can be given both of said two controlling-bars, and also that the joint for the
forward bar, G, can be shifted in a direction coincident with the line of progression.
The working position of the plow during the advancement of the machine can
therefore by such adjustments be determined with relation to the character of the soil
and the delivery of the same to the elevator. At the same time the plow is so
suspended and controlled that while being properly guided and kept to its work it will
have a perfect freedom and ease of movement, permitting it to line itself and other-
wise adapt itself to the work to be performed without unduly straining any of its
guiding or controlling adjuncts.
With reference to the action of bar G, the support or bearing for its vertical pivot
at the end farthest from the plow-beam can obviously be of any suitable construction;
but as a special construction of support herein also utilized as a brace the support 44
consists of a proximately rectangular loop or oblong socket formed at the lower end
of an upwardly-inclined and forwardly extending brace-rod, 59, (see particularly
Figure 4,) which is at its upper end secured to the side sill, 2, of the body-frame, the
lower loop portion, 44, of such rod being secured to and serving to brace one of the
standards of a frame for supporting certain sprockets for the elevator raising and
lowering chains, hereinafter more particularly referred to. In this connection it may
be observed that the lower substantially rectangular eye or loop, 44, at the lower end
of the brace-rod 59 serves as a most efficient bearing for the pivot-bolt 45, since both
its upper and lower horizontal portions can be provided with bolt-holes, so as to afford
bearings for the pivot-bolt both above and below the bar G. This loop or pivot
bearing 44 is also preferably braced by a rod, 60, arranged diagonally to the length
of the main body-frame, and at its ends attached, respectively, to the cross sill 4 and
the loop 44, as indicated in Figures 1 and 4, in which way, while the lower portion of
the upright 101 is in one direction braced by the rod 59, it is in effect braced in a
direction oblique to the rod 59.
As an extremely simple means for holding the plow down to its work in hard or
baked soil, the plow-beam is at its rear end provided with a standard, 61, Figures 1
and 8, which rises from the plow-beam to within convenient reach of the foot of an
attendant standing upon a rear platform, 62. The standard is at its upper end
provided with a suitable foot rest, 63, the whole constituting a foot-piece or presser-
bar, whereon the attendant may without delay throw sufficient of his weight to
keep the plow down to its work.
At the forward end of the plow-beam a hollow standard, 64, for the caster-wheel is
clamped against the end of the beam by clamps 65, the beam being preferably
concaved, so as to form a seat for such standard. Upon the lower end of this hollow
standard 64 is swiveled a hub, 66, as in Figure 3, a convenient arrangement being to
provide a two-part hub having an internally-arranged annular groove, 67, wherein the
heads of a cross-bolt, 68, extending through the standard, can be received preparatory
to bolting the two parts of the hub together. This hub is provided with a laterally-
arranged proximately V shaped bearing for a scraper, 70, which is adjustably bolted
upon such bearing and extended rearwardly therefrom into position for freeing the
caster-wheel from such dirt as, in road and ditch making, will otherwise adhere to the
caster-wheel to an extent to seriously interfere with its free running.
Referring particularly to Figure 3, it will be observed that the support or bearing 69,
while adapted to extend somewhat over the caster-wheel to provide a firm and reliable
support for the scraper, has its underside curved in a direction forwardly away from
the periphery of the caster-wheel, so that from the point where the lower side of the
support or bearing 69 is nearest the rim of the wheel the space between the two from
such point forward widens rapidly. The result of this arrangement is that should any
loose earth be left on the wheel by the scraper and carried forward by the rotation of
the wheel it will run off in place of collecting between the wheel and the under side
of the scraper support or bracket 69.
The caster-wheel is journaled in boxes provided at the lower ends of a pair of
arms, 71, which are bolted to the hub 66 and from such hub inclined downwardly to
the rear. The boxes are desirably adapted to contain a suitable quantity of lubricant

page_text: and constructed so as to effectively exclude dirt. The caster-wheel, in conjunction
with the scraper, constitutes a serviceable and important feature in a practically
successful grader and ditcher, and is particularly applicable to the class of work to be
performed.
The elevator F is arranged transversely with relation to the length of the machine
and extended under the main body-frame, so as to bring its receiving end in position
to receive the earth from the plow, which delivers the soil onto the endless travelling
elevator-apron or conveyer-belt 72, thereby permitting the belt to convey the same
upwardly to the discharge end of the elevator and there discharge the same either
onto the road or into a wagon, as the case may be.
The elevator comprises in its general construction one or more (but preferably a
plurality of) frames or sections arranged to constitute a desirably long-jointed roll-
supporting frame, which carries a suitable power-driven roll for operating the endless
belt, and idler-rolls for supporting and permitting the free running of the same.
The elevator is provided with a longitudinally-arranged guideway extending over
and along the belt from the receiving end to the discharge end of the elevator, and
having its sides arranged to keep the dirt and other matters delivered from the plow
to the belt from running off the side edges of the belt, thereby permitting the belt
which constitutes the hottom of such guideway to conduct the dirt and other matters
from the point of reception to the proper point of discharge. In addition to the
desirability of causing the plow to work in such position relatively to the receiving
end of the elevator and character of soil to be delivered as will cause a proper
delivery of the plowed-up soil onto the belt, it is bighly desirable and important that
all trash plowed up,-trash such as stalks, shall be properly guided and delivered into
the aforesaid guideway of the elevator, thereby not only preventing the same from
being left behind, but, what is of great importance, preventing such matters from
getting caught either about the journals or journal-boxes for the belt-roll at the
receiving end of the elevator or about any other parts of the machine at such locality,
it being found that the first arrestment of any stalks or trash at such points induces
such rapid subsequent accumulation of like matters as to require
a stoppage of the
machine and a loss of much time in removing the obstructions. To avoid such
objectionable features in a grader and ditching-machine, one of the guides or sides Fl
of the guideway along the elevator is at the receiving end of the elevator extended
from such point by a curved guard, K, which, in effect, forms a prolongation of the
guide arranged first to diverge from the opposite corresponding guide F¹ in a direction
toward the plow and to then sheer off reversely in a direction forwardly and away
from the plow, as best illustrated in Figure 14. This arrangement of guard K
relatively to the receiving end of the elevator and the plow serves to effectively
cause trash such as stalks and the like- to be guided to and thrown upon the
elevator-belt between the guides F', which extend longitudinally along such belt, and,
moreover, serves to prevent such trash from being thrown over either the journals of
the belt-roll at the receiving end of the elevator or the boxes 73, that are provided for
said journals. Should the guides F¹ be made of metal, the end of one of such guides
could be bent to form the guard K. The guides F¹ are, however, for the sake of both
economy and lightness, formed of wooden boards, and in such case the guard K is
formed by a bent metal plate secured at one end to the guide and at its opposite end
secured to the upturned end of a bar or plate, 74, arranged transversely to the length
of the elevator and secured to the lower edges of the elevator-frame at points
substantially below the belt-roll 75. Figure 8, at the receiving end of the elevator.
The guard K thus arranged also drops somewhat from its rear end, that is secured to
the guide to its forward end, that is secured to plate 74, as illustrated in Figure 1, in
which way, while the face of the curved guard opposite the plow may be vertical, or
nearly so, the guard as a whole lowers or inclines toward its forward end. The bar
or plate 74 serves both to brace the elevator at the receiving end and to support the
guard K, which latter serves in turn to support the forward end of the guide F1, to
which it is attached, and brace such guide against earth thrown against it from the
plow.

page_text: The guard K is stationed at one side of the plow, but set forward and away from
the plow to an extent to permit free passage of the soil from the plow to the elevator,
but will be found of extreme utility as a means for causing stalks and the like to
be properly deposited upon the elevator. Should, however, any stalks or the like
pass between the plow and elevator without being directed by the conjoint action
of the guard and plow onto the belt in the first instance, the guide F¹, which is to
the rear relatively to the advancement of the machine, will force such stalks or trash
onto the belt by reason of the prolongation of its forward end beyond the point where
the elevator-belt passes around the front belt-roll, 75, as at 76. This extended end 76
of one of the guides or side-boards of the elevator-guideway is supported and steadied
by a curved bar, 77, which is secured both to the guide and to the plate 74, that is
attached to the under side of the elevator-frame.
The elevator-frame, while practically a long frame extending continuously substan-
tially from the receiving to the delivery end of the elevator, is desirably divided into
a plurality of sections, the first division back of the receiving end of the elevator
being principally made to afford a joint adapted to allow the portion of the elevator
which extends out laterally from the machine to effect a side delivery from the latter
to be readily raised and lowered, while the next succeeding divisions occurring along
such laterally-extended portion of the elevator are to permit it to be shortened up
or lengthened by the removal of a section. These several frame-sections of the
elevator preferably involve a substantially similar construction, thereby preserving a
substantial uniformity of structure throughout the entire length of sectional frame.
The construction herein shown consists of a pair of oppositely-arranged upper side
bars, 78, as best shown in Figures 25, 28, and 35, and a pair of lower oppositely
arranged side bars, 79. The upper and lower bars are separated by suitable blocks
arranged at intervals along the frame and the whole braced and connected together
by appropriate cross-bars, some of which are desirably arranged transverse to the
length of the frame and others diagonally to such length.
a
The upper longitudinally-arranged side bars are provided with appropriate bearings
for a series of idler-rolls, 80, employed for supporting the upper leaf of the elevator-
belt, the bearings for such roll-journals being at points to set these upper idler-rolls
somewhat higher than the top edges of the said upper side bars, 78, in which way
the belt can be made of sufficient width to extend over the upper longitudinal edges
of the side bars 78, as illustrated in Figure 35. The spaces occurring alongside the
frame by reason of the elevation of its side bars 78 relatively to its side bars 79 are
covered by shields or plates 81, secured along their longitudinal edges to the upper
edges of the upper side bars, 78, and along their lower longitudinal edges secured to
the lower side bars, 79. The boards forming the guides F¹ are arranged over the
elevator-belt and raised therefrom to an extent to prevent frictional contact between
the belt and guides, which latter are held and braced in position by curved supporting-
bars 82, secured at their upper turned-down ends to the outer sides of the guide-
boards and at their lower ends secured to the lower side bars, 79, of the frame.
The shields or plates 81, which may be said to form sides or side coverings for the
elevator-frame, slope outwardly from the edge portions of the belt, which, as illustrated
in Figure 35, is of sufficient width to discharge any dirt that may work its way
under the guides F1 onto the sloping side plates or side coverings, 81, of the main
frame. In this way the plates or frame-sides 81 will shed any dirt that may find its
way to the outer edges of the belt, and by reason of the arrangement of the upper
leaf of the belt relatively to the frame-sides 81 such dirt as may fall off the edges of
the upper leaf of the belt will be prevented from getting onto the lower leaf of the
belt, it being understood that the falling of dirt within the elevator-frame would soon
tend to clog up its operative parts and render necessary a stoppage of the machine
and the laborious task of cleaning out such accumulation of dirt.
By setting the upper side frame-bars at a less distance apart than that at which
the lower side frame-bars, 79, are relatively arranged, the slope of the plates or frame-
sides 81 is readily attained, and at the same time provision made whereby the belt
can have its side edges extended somewhat beyond the ends of the upper belt-

page_text: rolls, 80, and brought into position to discharge any waste dirt onto the sloping
frame-sides 81.
The guides F are preferably arranged somewhat back from the edges of the belt-
that is to say, somewhat toward the longitudinal middle line of the belt-which
arrangement is conveniently attained by the supports 82. By this disposition of the
guides better results can be attained than where the edge of the belt travels directly.
opposite the vertical face of a side wall or side-board, particularly since in the latter
instance an objectionable quantity of the dirt that is being carried along by the belt
will sift between the guide and edge of the belt.
The portion of the elevator-frame which extends under the main body or platform
frame A of the machine can be made in one length or frame-section, while the
remaining portion of the frame, that is arranged to extend from the delivery side of
the machine, can be composed of one or more lengths or frame-sections, as may be
desired. To permit a free and desired extent of rise and fall on the part of such
portion of the elevator as projects from the delivery side of the machine, and also to
allow the same to be swung out of the way when the services of the plow and elevator
are not required, the frame-section of the elevator next succeeding the frame-section
that is suspended under the main or platform frame A can be and herein is suspended
from the main body-frame of the machine separately from the first or lower frame-
section of the elevator that is suspended from the main body or platform frame, in
place of being directly hinged to said lower frame-section.
The devices herein shown for suspending and adjusting the frame-section of the
elevator that is arranged under the main body or platform frame A and the devices
for raising and lowering the portion of the elevator that is arranged as a prolonga-
tion of said section are substantially as follows-that is to say, the frame-section of
the elevator which is arranged below the platform-frame A, and which constitutes
the receiving end portion of the elevator, is at the receiving end suspended by raising
and lowering chains 83 from a rotary winding drum or shaft, 84. This winding-
shaft 84 is mounted upon an elevated frame, L. that rises from the main body or
platform frame of the machine, and is provided with a hand-wheel, 85, by which it
can be operated by an attendant standing upon the rear platform, 62. In this
connection suitable means-such as a pawl-and-ratchet device (shown at 86)—can be
used for temporarily locking the winding-shaft 84 against rotation. The higher end
portion of the aforesaid frame-section of the elevator, which is toward the delivery side
of the machine, is suspended from the cross-sills 4 and 5 of the body or platform
frame by swinging arms or straps 87, Figures 8 and 11, which straps are provided
with several pivot-holes for the pivot-bolts by which they are pivotally attached to
the sills, in which way an adjustment of such connections between the body-frame
and this end portion of the elevator can be made when desired. The said elevator-
frame section is also further placed under control of an attendant by the inclined
connecting-rods 88, pivotally attached at their lower ends to the said elevator-frame
section at points toward its higher end, that is nearest the delivery side of the
machine, and at their upper ends connected with cranks or arms 89 (one of which is..
shown in Figure 8) upon a horizontal rock-shaft 90. The rock-shaft 99 is arranged
longitudinally with relation to the length of the machine and supported in bearings
in or upon the cross-sills 4 and 5 and the rear bolster, as indicated in dotted lines,
Figure 1, and is extended back to the rear of the machine, whereat a hand-lever, 91,
is provided for operating such rock-shaft and a swinging toothed bar, 92, arranged
for locking the hand-lever after it has been operated to adjust the elevator-section.
The vertically swinging or tilting portion of the elevator, which is suspended from
the main body-frame of the machine, and which is in the nature of an extension.
of the portion of the elevator that lies under the main body-frame, can be raised
and lowered by the raising and lowering ropes or chains 93.
These ropes or
chains 93 are attached to the elevator toward or near its delivery end and pass over
pulleys or sprockets 94, mounted upon the elevated frame L. This elevated frame
also provides bearings for a rotary winding drum or shaft 95, to which the chains 93
are attached,, so that by operating a hand-wheel, 96, upon the winding-shaft the

page_text: elevator can be raised or lowered from its delivery end. In this connection any
suitable locking device can be employed for locking the winding-shaft against
rotation, so as to conveniently hold the elevator-extension at the required angle.
As a means for hinging to the main body-frame of the machine the section or
portion of the elevator which constitutes an extension of the section or portion that
is arranged under the main body or platform franie, the frame-section of the
elevator that is to be thus hinged is provided at or adjacent to the corners of its
end that is nearest the body of the machine with hinge or bracket plates 97 and 98,
Figures 11 and 14, which are respectively attached by pivotal connections to the
lower ends of brace rods or bars 99 and 100. Each one of these hinge or bracket
plates 97 and 98. is bolted to the elevator frame-section, and is provided with a series
of bolt-holes for the pivot by which it is attached to its allotted supporting-bar.
In this way the end of the elevator frame-section next adjacent to the elevated end
of the elevator frame-section that is under the main body frame of the machine
can be adjusted in height, it being understood that the matching end of the elevator
frame-section that is under the main body-frame of the machine can, by means
herein before described, be adjusted in height in correspondence with the adjustment
of the adjacent end of the next succeeding section, and hence the two opposing
ends of such sections be maintained in proper relationship to afford a suitable joint
at this point along the elevator.
:
The inclined bars 99 and 100 are arranged transversely to the length of the machine
and secured to the framework of its body portion. These said bars are at their upper
ends conveniently secured to the middle longitudinal sill, 3, of the main body-frame of
the machine, and adjacent to their lower ends are desirably secured to the lower
portions of standards 101 and 102, which are bolted to the longitudinal side sill, 2, of
the body-frame, so as to rise therefrom and form portions of the elevated frame L.
By thus securing the inclined brace-bars 99 and 10 to the middle of the body-frame
and to the lower ends of standards 101 and 102, which drop below the main uprights
of the elevated frame L, said standards are braced by bars which afford pivotal
bearings for the hinged extension portion of the elevator-frame. In this connection
it will also be observed that the brace rod 59, having at one end a support, 44, for one
end of the swinging plow-beam guiding or controlling bar G, connects the lower end
of the upright 101 with the side sill, 2, and is arranged in a plane at right angles to
the plane in which the brace 99 is arranged, the brace 59 corresponding in this
respect to an inclined brace, 103, which serves to connect the lower end of the
upright 102 with the side sill, 2, as in Figure 4.
In order to adapt the guides F¹ to the joint occurring at the junction between the
receiving-end portion of the elevator, that is arranged below the main body-frame of
the machine, and the extension or delivery-end portion of the elevator, that is con-
trolled by the raising and lowering chains 93, the strips or boards 104, that are
supported from the elevator frame-section of the receiving-end portion of the elevator
and arranged to form the sides of a guide or passage way over and along the same,
can be arranged to have their higher ends simply lap the adjacent ends of the guide-
boards or guideway-sides 105, that are supported over the next succeeding elevator-
section, as in Figure 14.
The delivery-end or extension portion of the elevator, which is pivotally suspended
from the braces or bearings attached to the uprights 101 and 102, can be composed of
one or more lengths or sections, it being more desirable, however, to form it of a
plurality of sections; whereby for wide roads or other service requiring a long elevator
the several sections can be united to form an elevator of the desired length, whereas
when the required service demands a short elevator one or more of the sections can
be taken out.
The boards or guideway-sides allotted to said sectional extension portion of the
elevator can be made in sections corresponding to the number of elevator-sections
included in such extension portion and temporarily connected together, as illustrated
in Figures 26 and 27, wherein a couple of sections of such boards or guideway-
sides 105 and 106, are arranged end to end and connected together by a plate 107,

page_text: which is at one end secured to one board-for example, the board 105-and at its
other end provided with a slot, 108, to receive a bolt which is secured to the section 106
and provided with a nut that can tighten up against the slotted plate. This arrange-
ment permits the sides of the guideway allotted to any one section of the extension
portion of the elevator to be removed with such section when the same is taken out to
shorten the elevator, and on the other hand permits the sides of the guideway along
such extension portion of the elevator to be made continuous and rigid when the
sections of such extension portion are connected together.
In Figure 31 the extension portion of the elevator is shown as comprising three
frame-sections connected together at the joints by angle-plates 110, Figures 32 and 33,
which provide seats of half-sockets for and are temporarily bolted to the meeting end
portions of the lower side bars, 79, of the elevator frame-sections. In Figures 25 and 28
another way of temporarily connecting together these elevator frame-sections is
illustrated. In each of said figures two elevator frame-sections are shown connected
together by break-joints formed by hook-shaped bars 111, secured to the side bars of
one frame-section at an end thereof and adapted for engagement with links or
loops 112, that are secured to the next adjacent frame-section. In this way the joints
can be broken, as in Figure 28, and the sections entirely disconnected either for
shipment or for taking out any one of the elevator frame-sections, so as to shorten up
the elevator while on the other hand, when desired, the sections can be readily
connected by bringing the hooks into engagement with the loops, as in Figure 28,
and then bringing one section into alignment with the other section, as in Figure 25,
wherein the ends of the side bars of one frame-section are understood to abut squarely
against the opposing ends of the side bars of the adjoining section.
The frame-section of the elevator employed as the extreme end section at the
delivery end of the elevator is provided with bearings for the belt-driving roll 113,
which is preferably somewhat larger than the idler belt rolls. The boxes 114 for the
journals of these belt-driving rolls are adjustably held upon the elevator frame-section,
which at this end may have its lower side bars, 79, prolonged somewhat beyond
the terminals of its upper side bars, 78, so as to provide suitable seats or bearings
for the journal-boxes. While the journal-boxes 114 can be adjusted in various ways,
in order to either tighten or line up the elevator-belt, a simple and preferred way is
to provide the boxes with base-plates having slots for the reception of bolts, by which
they can be held down upon their seats or bearings, and to employ short adjusting
hook-bars or hook-bolts 115, Figure 30, having bearings in brackets or angle-
plates 116 on the ends of bars 79 of the end elevator frame-section and arrranged to
place their hook ends in engagement with suitable eyes or holes in the base-plates of
the boxes, in which way by adjusting the nuts 117 on threaded portions of such
adjusting-bolts the required adjustment of the journal-boxes can be effected.
The boxes 114 are each adapted to contain a suitable quantity of lubricating matter
to insure the free running of the belt-driving roll, and in this connection it will be
observed that the boxes 73 (see also Figures 18 and 19) for the journals of the belt-
roll 75 at the receiving end of the elevator are likewise adapted to contain a suitable
quantity of lubricating matter, and are herein rendered adjustable by adjusting hook-
bolts 118, Figure 14, applied in a manner similar to that in which the hook-bolts 115
are applied for adjusting the journal-boxes at the delivery end of the elevator.
It is understood that should it be desired to shorten the elevator by removing a
section the middle section of the extension portion of the elevator can be removed,
(where, for example, such extension portion comprises three sections,) after which
removal the extreme outer section carrying the large belt-driving roll can be coupled
to the section that is hinged to supports at the side of the main body-frame of the
machine.
To prevent dirt from falling from the upper leaf of the belt down between the ends
of the upper frame-section side bars, 79, and the driving-belt roll 113, shields 119,
Figures 30 and 34, which preferably consist of pieces of some suitable flexible material;
are attached to the bars 79 and arranged to cover portions of the ends of the belt-

page_text: driving roll, thereby preventing dirt from the load that is being carried along the
elevator from falling upon the lower leaf or fold of the belt.
The chain or link-belt sprocket 120, that is secured upon the axle or one of the
journals of the belt-driving roll 113, is covered by a casing or shield, M, which is
removably attached to the frame-work of the elevator at this point. This shield is
particularly serviceable as a means for preventing operators from getting caught by
the sprocket at the delivery end of the elevator, it being found that in delivering to
wagons the drivers or attendants thereon are liable to drive too close to the elevator.
The link-belt N, herein employed for operating the belt-driving roll at the delivery
end of the elevator, passes over the sprocket 120 and extends back to the body of the
machine, where it passes around and is operated by a belt-driving sprocket, thereby
providing between the two sprockets a flexible power-transmitting connection, which
permits the elevator to be readily raised and lowered from its delivery end.
Where a removal of one or more of the sections of the extension portion of the
elevator is contemplated, the belt will be made in sections proportioned in length to
contemplated change in length of the elevator, so that by removing one or more
sections of the belt it can be adjusted in length to the change in length of the elevator.
As a simple and desirable construction of connection between the meeting ends of the
lengths or sections of belting, a stout flexible strip, 121, Figure 10, is along a portion
of its width secured to one of the meeting edge portions of the belt by rivets 122 and
along the opposite portion of its width detachably secured to the other one of the
meeting edge portions of the belt by short bolts 123, provided with nuts that can be
tightened up in order to clamp this transverse connecting strip and belting together.
At the ends of this strip are short flexible pieces 124, arranged transversely to the
length of strip 121 and alongside of and parallel with the longitudinal edges of the
belting. These end pieces, 124, can be separate from or integral with the cross-
strip 121, and are, like the cross-strip, secured to one end portion of the belt by rivets
and detachably secured by short bolts and nuts to the opposing end of the belting.
This arrangement permits the disconnection of the belt-sections by unscrewing the
nuts and removing the bolts, and is of particular value in an elevator for the purposes
of a machine of this character, it being observed that the pieces 124 prevent wear and
tear along the longitudinal side edges of the belt at the joint, and that with the com-
paratively narrow strip 121, secured across the belt, and the comparatively narrow
strips 124, parallel with the length of the belt, a strong and at the same time sufficiently
flexible joint is provided.
To prevent the lower leaf of the elevator belt from sagging to an undesirable extent,
the elevator is provided at one or more points along its length with one or more idler
belt-rolls, 125, over which the lower leaf of the belt may pass. These rolls 125 are
conveniently journaled in bearings secured to the under sides of the longitudinally-
arranged side bars, 79, of the main frame, so as to place the rolls in proper position
for upholding the lower leaf of the belt, one of such belt supporting rolls being in
Figure 8 mounted in bearings at the under side of the portion of the elevator that
extends under the main body or platform frame A of the machine, while in Figure 31
a like roll is shown similarly applied to the extension portion of the elevator.
In addition to the set of belt-rolls 80, arranged in a plane proper for supporting the
upper leaf of the elevator-belt, the elevator is provided with a second set of idler bélt-
rolls, 126, Figures 8 and 31, arranged in a plane below the plane of the rolls 80 and
mounted with relation to the cross bars or braces of the elevator-frame to prevent the
lower leaf of the belt from coming in contact therewith, it being seen that the belt
passes under those guard-rolls 126, as in Figure 8.
To insure the requisite rigidity of the extension portion of the elevator, particularly
where such extension comprises several connected frame-sections, longitudinally-
arranged side truss-rods, 127, can be employed, as in Figure 11, wherein the appli-
cation of one of such rods is illustrated. In said figure the truss-rod 127 is somewhat
bowed or bent down intermediate of its ends and at its ends adjustably attached to
brackets or bearings 128; one of which is secured to a side of the elevator frame-

page_text: section that is next adjacent to the frame-section which extends under the main body-
frame of the machine, while the remaining one of the bearings 128 is, as indicated in
dotted lines, attached to a side of the elevator frame-section that is at the delivery end
of the elevator.
To the elevator frame-section that is understood to be intermediate of the said two
sections carrying bearings for the ends of the rod a cleat, 129, is applied and arranged
to bear downward against the rod, which, when tightened up by any ordinary
mechanical means-such as by nuts on its threaded terminals-will engage and bear
upwardly.against the lower bearing-surfaces of the cleats 129. The rear supporting-
wheels, 130, of the machine are loosely mounted upon a rotary axle, P, Figure 20,
and prevented from running off from the ends of such axle in any suitable way-for
example, by collars 131, bolted to the ends of the axle and received within suitable
recesses, 132, in the outer ends of the hubs-means being provided whereby during
the advancement of the machine connection may be established between the rear
wheels and rear axle, as hereinafter particularly set forth.
The rear axle, P, has at two or more points bearings in boxes Q and Q, that are
clipped to the lower bar, 133, of the rear bolster, R, herein provided for supporting
the rear end of the main body or platform frame of the machine, which frame may,
for example, have its longitudinal sills secured upon the upper bar, 134, Figure 14, of
the rear bolster. These boxes may have a like construction, with the exception that
the box Q' is provided with a bearing, 135, Figures 23 and 24, for the rear end of a
rotary shaft that carries a clutch, as hereinafter described. With regard to certain
features of construction involved in all of these boxes, each box is provided with
suitable bearings for the rotary axle and with one or more (but preferably with a
couple of recesses, 136, formed in their lower interior axle bearing-surfaces, and
providing receptacles into which lubricating matter-such as cotton or other waste
and some suitable lubricant-can be introduced through passages 137, which are
formed to extend downwardly through a side portion of the box, as illustrated in
Figure 24, wherein one of such passages is arranged to form the entrance to a
lubricant-receptacle, 136. In this way a quantity of lubricating matter sufficient to
last a long time can be introduced into. boxes, thereby permitting the easy running of
the axle. The boxes are divide 1 or made in halves to permit them to be readily and
properly cast, it being obvious that the parts of each box can be securely bolted
together and the box firmly attached to the wooden or other bar 133 by clips 138.
As a means for connecting one of the rear wheels with the rotary axle P during the
advancement of the machine, so as to permit the elevator-belt to be driven from such
axle by means hereinafter described, and to automatically disconnect said wheel from
the axle in backing the machine, the rotary axle is at a point along its length provided
with a hub, 139, Figures 20 and 21, which is keyed upon the axle and provided with
ratchet-teeth that are to be engaged by a pawl on the hub of the supporting-wheel
when the machine is drawn forward, said pawl, however, being arranged to ride over
the ratchet-teeth in backing the machine. The hub 139 herein shown is provided at
one end with an annular chamber, 140, containing an annular line of ratchet-teeth, 141,
and the hub 142 of the rear supporting-wheel next adjacent to the internally-toothed
hub 139 is at its inner end provided with a cap, 143, secured to the hub and carrying
one or more (but preferably a couple of) spring controlled pivoted pawls, 144, which
during the advancement of the machine engage in the line of ratchet-teeth 141, but
ride over such teeth in backing.
The hub 145 of the rear supporting-wheel, opposite the rear supporting-wheel herein-
before last referred to, like its companion wheel-hub 142, carries one or more pawls
arranged to engage a ratchet on the rotary axle during the advancement of the machine,
but to ride along the ratchet-teeth in backing. The ratchet for the pawl or pawls
carried by the rear-wheel hub 145 is, however, formed with or rigid upon a bevel-
gear, 146, which can have its central portion adapted to provide a hub, 147, which,
like the ratchet plate or hub 139, is herein provided with an internally-arranged set of
ratchet-teeth for one or more pawls understood to be pivoted to a cap, 148, that is fitted
to the wheel-hub 145 and equipped with one or more of such pawls similar to the

page_text: cap 143; that is fitted to the rear-wheel hub 142. The said gear 146, having a hub, 147,
provided with an internally-arranged set of ratchet-teeth, is shown in Figure 4,
wherein the nearest rear supporting-wheel is understood to be removed for convenience
of illustration. The bevel-gear 146 is rigid upon the rotary axle P, and is employed
for operating a rotary shaft that forms an element in the power-transmitting connec-
tion between the elevator driving-belt N and the gear 146.
By the foregoing arrangement of rotary axle extending through the boxes and
provided with a driving-gear and the means set forth for establishing a rigid connection
between the wheels and the axle during the advancement of the machine, but
permitting the wheels to run loose upon the axle in backing, provision is made for the
application of a comparatively large quantity of lubricated cotton or other waste at
the points where the axle turns in its bearings, it being observed that the impracti
cability of supplying the hubs of the rear wheels with such lubricating matter will be
obvious. In this way, therefore, the axle bearings can be kept lubricated for a long
time, and at the same time a simple arrangement provided for driving the link-belt N
from the wheels, which, during the advancement of the machine, will be in rigid
connection with the axle, which in turn directly causes the rotation of gear 146.
The box Q¹ for the rear axle is provided with the herein before-mentioned bearing 135,
having a passage for the introduction of any suitable lubricating matter, which said
bearing provides a support for the rear end of a short rotary power-transmitting
shaft, 149. (Shown in Figures 1, 4, 14, and 15, but best represented in Figures 14
and 15, wherein the clutch R, for connecting and disconnecting the driving-power
with and from the link-belt N, is particularly illustrated.) The rotary shaft 149 is
driven from the gear 146 when the latter is operated, to which end a small bevel-
gear, 150, arranged to engage the gear 146, is secured upon the shaft 149.
The clutch gland or member 151 is keyed upon shaft 149, so as to rotate with but
slide along the same, and an opposing gland or member, 152, is loosely fitted upon
the shaft. The clutch-gland 152 is adapted to provide a sprocket for the link-belt N,
by which the belt-roll at the delivery end of the elevator is driven, and is further
provided at one end with teeth or lugs 153, Figure 16, that are to be engaged by similar
teeth or lugs, 154, Figure 17, on the shifting clutch-gland 151 when the latter is shifted
in position to throw it in clutch with the gland 152. The shifting clutch-gland 151 is
made substantially bell-shaped, and the opposing gland 152 is provided with an annular
flange, 155, which provides a recess or chamber within which a portion of the flared
end of the shifting clutch-gland is received when the two glands are in clutch. When,
therefore, the two glands are in clutch, the flange 155 covers the end of the flared
portion of gland 151, within which latter the teeth 154 are located, and hence all dirt
falling upon the clutch will be shed off and effectively prevented from getting into and
clogging up the clutch.
The shifting gland 151 carries and is free to rotate within a sleeve, 156, which is
held against rotation by an inclined bar, 157. This bar, which is at one end pivotally
attached to the sleeve 156 and at its opposite end attached to the main body-frame of the
..machine, (for example, to the middle longitudinal sill, 3,) is capable of sufficient move-
ment to permit the desired extent of end motion on the part of the sliding clutch-gland.
The hand-lever 158, Figure 4, for example, rises from the rear attendant's platform
on the main body-frame of the machine, so as to be within convenient reach of an
attendant standing thereon, and is at its lower end connected by the connecting-rod 159
with one end of a link or lever, 160. The link or lever 160, which is at its forward
end pivotally connected with the operating-rod 159, is at its rear end pivotally attached
to a bearing piece, 161, that is secured to the lower bar, 133, of the rear bolster. This
link or lever 160 is also connected with the bar 157 by a link or lever, 162, which is
at one end pivotally attached to the bar 157 at a point near the sliding clutch-gland
and at its opposite end pivotally attached to the link or lever 160 at a point inter-
mediate of the ends of the latter. The operation of these links or levers is illustrated
in Figure 15, wherein their relative position when the clutch is closed is shown in full
lines and their relative position when the clutch is open indicated in dotted lines.
By such arrangement the links or levers 160 and 162 co-operate to provide a compound
1445 ↓ 4

page_text: lever or toggle which when the clutch members are closed together locks them in
clutch, since in such case the links or levers 160 and 162 are in line, substantially
as shown. The clutch as a whole possesses great strength, and, together with its
operating devices, provides a clutch mechanism particularly adapted to a machine.
of the present kind.
As hereinbefore mentioned, the rotary shaft 149 is at its rear end journaled in a
bearing provided by one of the boxes for the rear axle. The forward end of this
rotary shaft is mounted in a box, 163, adapted to receive a suitable quantity of
lubricating matter, and herein secured to the inclined brace-bar 100, which, it will be
remembered, in addition to being secured to the lower end of a standard, 102, of the
elevated frame L as a lateral brace for such standard, also provides a bearing for a
pivot by which a bracket-plate, 98, Figure 14, attached to one corner of the hinged
elevator-frame extension, is supported, thereby providing a compact economical
arrangement of parts, which, while affording the greatest required strength, tends to
greatly simplify the general construction.
The front supporting-wheels 164, of the machine are secured to the forwardly-
arranged rotary axle S, which at desired points between the wheels passes through
boxes T. These boxes are secured by clips or other suitable fastenings to a bar, 165,
that is arranged over and parallel with the axle and adapted to support the front
bolster, U. The boxes T are adapted to provide receptacles for lubricating matter,
whereby a lubricant can be applied at the points where the axle turns in the bearings
afforded by such boxes. The formation of the lubricant-receptacles in these boxes
can be similar to the formation of lubricant-receptacles in the boxes for the rear axle,
it being observed that in Figure 36 the boxes T are provided with receptacles 166,
containing lubricant cotton or other waste, which can be introduced through
passages 167, formed in lateral enlargements 168 of the boxes, as indicated in
Figures 14 and 37, wherein such passages are understood to substantially correspond
with the construction of passage 137. (Shown in Figure 24.)
The front bolster, U, is pivoted by a king-bolt, 169, upon the bar 165, to which
the boxes T are clipped, the arrangement of bearings for such bolt being particularly
illustrated in Figures 37, 38, and 39. The front bolster is also provided with a half-
circle, V, which is firmly secured by clips or bolts to the lower bar 170, of the frame
that constitutes the bolster, as best indicated in Figure 36. The bar 165, which may
be termed the "axle-bar" is provided upon its upper side with suitable bearings, 171,
Figure 36, for the half-circle V, which latter is desirably made of wood and provided
along its under side with a metal wearing-surface formed by a metal strap, 172,
secured to the under side of the wooden half-circle and bent reversely at its ends, so
as to permit the securement of its terminals to the upper side of the wooden half-circle,
as indicated in Figure 37.
The lower bar, 170, of the front bolster is at its middle embraced by a bent plate
or clip, 173, Figure 39, which is bolted to said bar, and at its ends, which extend
laterally to the rear from the bolster bar, provided with bolt-holes for the king-
bolt 169.
A bent plate or clip, 174, is bolted to the middle of the axle bar 165, but formed
to drop somewhat below such bar, so as to provide room for the rotary axle, which
at this point passes between the bar 165 and the lower horizontal end portion of
the clip. The upper and lower horizontal end portions of clip 174 extend back
from the axle-bar and axle and are provided with bolt-holes for the king-bolt,
by which the two clips 173 and 174, that are respectively secured to the bolster
and the axle-bar, are pivoted together. The lower clip, 174, provides a bearing for
the upper clip and has its horizontal end portions braced by angle-plates 175, which
are fitted between and bolted to said end portions of the clip 174. These angle-plates
are also bolted to the rear side of the axle bar 165, to which end they can be secured
to the axle-bar by the horizontally-arranged bolts employed for attaining a secure
connection between the axle-bar and the clip. In this way the clip 174 and the angle-
plates 175 are respectively clamped against opposite sides of the axle-bar by the bolts,
c

page_text: for which latter they afford suitable bearings. Said clip and one of the angle-plates
may also afford bearings for an eye-bolt, 176, to which the forward end of the draft-
chain H can be attached, in which case the eyebolt desirably extends through the
axle-bar 165 as well as through one of the angle-plates and the vertical portion of
clip 174, such arrangement affording an exceedingly substantial bearing for the bolt
and permitting its securement at a point which will place its connection with the
draft-chain H back of and substantially in line with the pole 177, Figure 14, of the
machine.
-
The king-bolt extends both above the clip 173 and below the clip 174. The end of
the king-bolt which is thus extended above the upper clip has a bearing in the forward
end of a bent bar, W, while its end which is extended below the lower clip has a
bearing in the forward end of an inclined bar, 178. The bar W is bent at a point
between its ends, and at its bend is divided, so as to embrace a portion of the middle
longitudinal sill, 3, of the main body or platform frame, the division of the bar W at
such point being shown at 179, Figure 14. The two sides of this divided portion of
the bar W are firmly bolted to the sill 3, thereby rigidly holding the bent bar in place.
The bar W is by such arrangement formed with a pair of legs extending downwardly
from its point of securement to the body-frame, the front leg, 180, being extended
forwardly and inclined downwardly to a point proper to provide a bearing for the
upper end of the king-bolt, while the rear leg, 181, which drops down from the sill, is
at its lower end bolted to the rear portion of the half-circle V, so as to establish a
rigid connection between such portion of the half-circle and a middle portion of the
main body or platform frame of the machine.
As a further means for bracing and steadying the balf-circle, short inclined brace-
rods 182, arranged diagonally to the length of the machine, are at their upper ends
secured to the middle longitudinal sill, 3, and at their lower ends secured, to the half-
circle at points forward of the connection between the half-circle and the bar W,
although the bar W is generally sufficient as a stay and support for the rear or middle
portion of the half-circle without the auxiliary brace-rods, which, however, may be
employed in machines of the largest grade.
The inclined bar 178 is at its rear upper end suitably secured to the main body or
platform frame of the machine and at its lower end provided with an eye or bearing
for the lower end portion of the king-bolt, which, however, may, if desired, be extended
below such bearing to an extent to provide between the same and the head on its
lower end room for an eye on the forward end of a stay-rod or stay-chain, 183,
arranged to extend from king-bolt back to the elevator, as in Figure 14, it being
observed, however, that this stay-chain could at its forward end be attached to any
other suitable device carried by the axle-bar or by the front bolster.
As a brief summary of several features of construction hereinbefore set forth in
detail and serving to attain these last-mentioned ends, it may be observed, in con-
clusion, that the elevated frame L, while serving to support the winding drums or
shafts for the chains by which the receiving and delivery ends of the elevator
can be raised and lowered, also provides at the lower ends of its uprights 101 and 102
supports for bearings allotted to the pivots at the hinged end of the elevator-
extension. These uprights therefore require rigid connection with the main
body-frame of the machine, both for the purposes of the upper portion of frame L
as a whole and for their service as supports for said pivot-bearings. To such
end one of these uprights is braced in one direction by a rod, which affords a
bearing for the end of bar G, and in an opposite direction braced by a short brace, 60,
which, in conjunction with said rod, constitutes a double brace, said upright being
further braced by a bar, which in turn affords a pivot bearing for one of the pivots
at the hinged end of the elevator-extension. The remaining upright of frame L is
braced by a bar which, while providing a pivot-bearing for one of the pivots at
the hinged end of the elevator-extension, also supports a journal-box for one end of
the power-transmitting shaft 149.
The front and rear axle-bars, 133 and 165, can be made of wood; and also the

page_text: construction and mode of securement of the half-circle V permit it to be made of
wood, and at the same time to involve all desired rigidity and strength.
