page_text: I, HERBERT JOHN HADDAN, of the firm of Herbert & Co., Patent Agents, of
67 Strand, London, 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 :-
This invention relates to Side Hill plows, and more particularly to a type in which
a single mold board with its attached share is made to swing from one side of the beam
to the opposite side of this beam to permit a return furrow to be made by the plow.
The primary object of the invention being to provide a reversible pointed turf slicer,
which is adapted to change its lower cutting edges automatically when the mold
board and share is made to change its position to cut furrows in reversed directions,
the shaft on which the turf slicer is secured to reverse its edges being provided with
an actuating device that permits an adjustment to afford greater or less lateral
swinging motion of the plow beam when the mold board and share are reversed.
A further object of the invention is to provide a vertical box swivel bearing in the
body of the beam of the plow to afford a stable pivot joint where the beam connects to
the standard.
A further object is to furnish a double faced landside which is adapted to be firmly
locked to the lower portion of the standard when these parts are in secured adjustment,
the lock being effected by a hook connection without the use of bolts or screws.
A further object is to provide means whereby a simultaneous change of position
relatively of the beam, slicer, and handles is effected when the mold board and its
attached share is released and made to swing into an adjusted or secured position
on the opposite side of the beam, to permit the plow to be operated in reversed
direction.

page_text: A further object of the invention is to furnish a double pointed lozenge or rhomb
shaped turf slicer, that by its peculiar form permits a reversal of position on a
revoluable supporting shaft, and thus afford a duplicate slicer for use when the opposite
edges have been dulled or injured by use or accident.
With these objects in view the invention consists in certain features of construction
and combinations of parts that will be hereinafter fully described and pointed out in
the claims.

A, represents the beam of the plow, it is made preferably of metal and is given an
approved form to insure strength as well as lightness of its body. The forward end of the
beam A is provided with the usual depth wheel a, that is secured to rotate on a vertical
bar a', which is perforated with spaced holes a², to permit a change of horizontal plane
of the wheel. The hook bis forked at its rear end to embrace the sides of the beam A,
which has a series of spaced perforations 6, made to receive a transverse bolt b² and
permit a change of adjustment of the draft hook b as may be required to regulate the
raft of the plow.
At a point B on the beam A, a circular enlargement or boss is made on its body
to allow a slightly round orifice B', to be formed in the boss B, this aperture
being tapered from its top edge to the bottom; the base wall c of the hole B', is
centrally perforated for the reception of the bolt c¹. A barrel washer C which is
made with two projecting circular flanges c³, c, that project from the centrally
perforated body C₁, to have a neat moving fit within the orifice B¹, at the upper
and lower edges of this tapered hole. The lower end of the barrel washer C, has
a short cylindrical portion c, made to project below the lower flange c³, of the
washer and have a contact upon the upper surface of the standard D. The
standard D, just mentioned is made of metal, and is preferably given the form
exhibited in the drawing, the upper part D¹, consists of a centre plate which is web
flanged on its edges to afford strength and lightness, the lower part D³, consisting
of a single plate as shown. The barrel washer C has its lower end that
projects through the orifice made for its reception in the beam A, of such relative
length as to afford a contact bearing upon the upper face of the standard D so
that the bolt g which is inserted through the hole in the projecting end g¹ of the
standard D and penetrates the centre of the barrel washer C will by means of its
bead g² formed on it to engage the standard D, and a securing nut g³ adjusted
to bear firmly on the upper surface of the barrel washer hold the beam A in
secured swinging adjustment with the upper face of the standard D, the nut being
forced to seat firmly and thus prevent accidental displacement of the bolt and the
connected parts held by it.
The mold-board E and the share E¹ are bolted together in secure manner, and are of
appoved form of construction. The mold-board and share are pivoted to the front and
rear ends of the lower part D of the standard to permit the semi-revolution of these
parts on the pivotal points of suspension d, d' as shown in figure 4. The front end of
the connected share and mold board have their pivot point d' formed on the
standard D, the pivot that projects from the front edge of the standard engaging a

page_text: proper perforation male in a shoulder formed on the reinforce plate E², which holds
the mold board and share in connection by countersunk bolts inserted through these
connected parts. The rear portion of the mold-board E is pivotally connected by the
T-shaped bracket arm F', which is secured to the mold-board and made to project a
sufficient distance to permit an engagement of the socket formed in its free onde with a
cylindrical projection made on the rear face of the lower part of the of the standard D.
The stay bolt e¹, provided to hold the arm F¹, in secured adjustment with the
standard D, it being made to engage with the arm F¹, and a lug e², formed on the
inner surface of the reinforce plate E, to stiffen the arm F, and prevent a rearward
springing action of this arm. The standard D, has an enlargement made on its body
to provide sufficient material to allow the formation of an inclined circular aperature G,
that perforates it from front to rear edge, the "pitch" or degree of inclination of this
orifice being such as to give a proper position to the shaft H which, is inserted to rotate
in it.
The forward end of the shaft H is flattened to provide a seat to receive the slicer
blade H The turf slicer blade H', is given a lozenge or rhomb form as shown in
figures 1 and 4, it is secured in place on the shaft H by a bolt inserted through
corresponding holes formed in the end of the shaft and the slicer, the hearing end of
the shaft laying between parallel shoulders formed upon the rear face of the double
pointed slicer H¹, to prevent a lateral movement of the attached slicer.
The length of the shaft H is so proportioned to the projecting point of the plow
share, that the point of the diamond shaped slicer H', will be slightly in advance of
the point of the plow share.
The body of the slicer H¹ is made concave on its face in a manner to afford a sheer
edge on each side, these edges being rendered more effective by a bevel formed upon
the rear face of the rhombus to provide a jointer or knife edge which inclines at such an
angle rearwardly, that the blade will have a shear action upon the stiff turf or surface
soil to slice it in advance of the plowshare, and by its efficient action greatly aid the
operation of plowing. The double point provides a duplicate slicer that can be
substituted for the one first used, when it is dulled or injured by use or accidental
contact with a rigid obstruction.
The rear end of the shaft H is made to project through the standard body to receive
a cam I. This cam consists essentially of an oval diski, of a proper thickness, which
is provided with an integral flange i, that projects radially from its rear edge
sufficiently to form an abutment for the inclined depending limb A2, formed integrally
upon the rear end of the plow beam A, the degree of inclination of this limb A2, causes
it to lay with its rear face in a plane parallel to the opposite face of the standard D,
the collar or flange being located between these opposed surfaces, the disk i, of the
cam is held in place to have working contact with the side walls of an abolong slot
made through the limb A¹, to receive this disk. The cam I, is slotted on its lower
side to allow it to embrace the shaft H, and be moved a limited distance vertically.
The front face of the cam I has a parallel edged plate or arm, made to extend from
the edge of its disk i, to engage shoulders or flanges made on the inner face of the
forked arm J, which is also given a variable position upon the shaft H, immediately
in front of the cam J, and is adjustably secured to the same by the set screw 23.
The portion of the arm J which has secured contact with the arm of the cam I is
attached to this arm by a stud bolt ", which projects from the face of the arm to enter
and slide in a short slot, made in the upper end of the forked arm J.
The lower portion of the arm J is slotted to form two parallel limbs k, the slot k', thus
produced, permitting the insertion between the limbs of the free end of the lever K³,
that is a forward projection of the tripping plate K, which is seated upon a rearward
extension m of the standard D.
The tripping plate K, is pivoted at m, to vibrate laterally and give a limited rocking
motion to the shaft H, as will be explained.
Upon the tripping plate K, the handle carrier L, is mounted, this piece Lis
pivoted at the front end n, to the standard D, a lug or boss extension formed on this
piece L being held to move by a bolt n inserted through this end and also through an

page_text: car n² formed integrally on the standard D immediately above it, the bolt n¹, being
secured by a nut n³ that is inserted in a slot formed at a proper point in the body of the
standard D, below the face on which the handle carrier L is located. The carrier
plate L has the vertical flanges o, made to project from its face to receive and retain
in fixed contact the handles M, these flanges o being given a sufficient angular
divergence to hold the handles M, in proper position with regard to each other. The
inclination of the carrier plate Lis such as to project the handles diagonally upward in
the same plane a proper distance for convenient use.
The tripping plate K has the laterally extending hooks p,p', bolted to recessed ears
at the points p², these hooks p, p, engaging the edges of the brackets arm F alternately
as the mold board is adjusted to either side of the beam A, a spring latch r. is made to
project from the under surface of the standard D to engage notches 1, 2, made to
receive the beveled edge of the free end of this spring latch, the notches being made
to register with the spring latch when either one or the other of the hooks p,p³,
are in locked contact with the bracket arm F¹, as before mentioned.
It is evident that the pressure of the foot of an operator exerted upon the edge of
the hook p or pl, that is free, will cause a release of the opposite engaged hook and
permit a reversing movement of the mold board and share by simply raising the plow
by its handles, and swinging the same laterally, a lowering of the plow will cause the
bottom of the land side to seat upon the ground and effect latching of the mold-
board with the hook that is in engaging contact with the bracket arm F.
While the latching movement just described is being executed the engagement of
the lever K, with the limbs k, of the arm J will give a rocking motion to the shaft H
which will be so graduated as to cause the proper alignment of the slicer H², with the
share below it to cause it to cut properly. The plate L that supports the handles M
is acted upon by the vibrations of tripping plate K as the point of pivotal connection
effected by the bolt s is a short distance to the rear of the pivot bolt m³, and a con-
sequent leverage is afforded to move the handles laterally, they being pivoted to
vibrate on the bolt n', this movement side wise of the handles is necessary to bring
them alternately in proper relative position to operate effectively when the plow is
used as a right or left hand plow as occasion demands.
The partial rotation of the shaft H, and cam I causes the bearing of this cam disk
upon the contact surface of the depending limb of the beam A to give a side motion
to this end of the beam, the point of pivotal motion being the bolt c, that connects the
beam and standard of the plow. It is evident that a movement of the tripping plate
to release one of its latches p p will cause the simultaneous adjustment of the beam A,
slicer blade H¹, and handles M, and that this movement will be effected while a
change of the position of the mold board is being executed; the adjustment of these
four elements being made with equal facility when the plow is being changed for use
on either side of the beain.
The sliding plate that is fixed to the cam and has an adjustable connection with
the cam disk i, is provided to furnish a means of changing the throw of the cam as
by setting the cam higher or lower, the throw of this cam and the lateral vibration of
the attached plow beam will be increased or diminished as the case may be, and the
position of the slotted arm J may also be changed to throw the beam and also the
plow handles farther to one side or the other of the pivotal centre of the tripping
plate K, by slacking the set screw, then moving the arm laterally on the supporting
shaft H, and resetting the tightening screw to secure the adjustment.
The land side O is secured to the lower edge of the standard D it being channeled
longitudinally to fit a correspondingly shaped tongue t, made of the foot of the
standard. The tongue and channel of these engaged parts are given a regular taper,
being thicker at the rear end, or heel of the standard and regularly decreasing in
thickness toward the front edge of the standard to form a close fit of the double
landside upon its seat when it is in position thereon.
A perforation is made in the front end of the double walled landside O to receive
the dowel d, that also affords a pivot point for the share and mold-board of the plow,
a shoulder u, is formed on the walls of the land side O to abut against the front edge

page_text: of the standard D, and a hook u' is formed on the lower surface near the rear end of
this standard to engage with a cross bar secured transversely between the walls of the
landside at a proper point for such engagement, the sides of the landside O are formed
alike, and these side faces are made alternately to line with the vertical wall of the
plowshare, as these similar faces of the double land side are brought successively into
position with this upright face of the plow share.
The lower surface or tread of the landside O is made to droop slightly toward the
rear end to give the point of the plow share a proper dip to hold it at a proper depth
which is controlled by the position of the depth wheel at the forward end of the beam.
