page_text: I, WILLIAM HEWITT, of the City of London, in the Province of Ontario, Canada,
Mechanic, 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 a Harrow, having a wheeled carriage, and seat for the
driver.
And it consists of the improved construction and combination of parts of the same,
as will be hereinafter more fully described and claimed.
Reference being had to the accompanying drawings, already mentioned, wherein,
Fig. 1. is a rear end elevation of a Sulky Harrow, embodying my Invention, and
showing the harrow sections raised.
Fig. 2. is a sectional view on the line, x, x, of Fig. 3.
Fig. 3. is a plan view of a sulky harrow, embodying my Invention.
Fig. 4. is a detail perspective view of a part of the pivotal tongue and connections,
this view also shows a portion of the frame on which the tongue is pivoted.
Fig. 5. is a detail perspective view of the standards, and axle, and a portion of the
sulky frame and harrow section.
H, H, and, H³, designate a harrow formed in three sections; and, A, designates
the axle; B, B, the wheels; and, F, the frame of the sulky.
As shown in Fig. 3, of the accompanying drawings, the harrow sections, H¹,
and, H³, are formed with knuckles, k, through which brackets, ½, pass, and the latter
are secured to the barrow section, H2, but the knuckles, k, may be secured to the
central section, H²; and the bracket, h, may be secured to the outer sections, H', and H³,
if preferred; and these brackets, h, are formed much longer than the knuckles, k,
to permit the outer sections, H¹, and, H³, to give or move back and forth independent
of the central section, H2, for the purpose of easing the draft of the harrow when
turning or passing over obstructions.
As shown in Fig. 2. of the accompanying drawings,
P, designates a pulley, which revolves perfectly free in bearings secured to the
evener, E; and, C, designates a chain, secured at one end to the frame, F, of the
sulky, this chain, C, then passes over the grooved pulley, P, and is secured at

page_text: the other end to the central harrow_section, H2, for the purpose of loosely attaching
the harrow sections to the frame, F, of the sulky, at the same time, the harrow
will not be affected by the tilting up or down of the sulky frame, because the chain, (,
will run over the pulley, P, this prevents any tilting motion of the sulky frame
from affecting the harrow sections, the harrow sections will therefore always rest and
draw level on the ground, when lowered for operation.
D1, D2, designate chains, for suspending the evener, E, and double tree, D,
respectively, from the tongue, T, and clear from the ground, or harrow sections,
to. prevent these devices from being broken or damaged, by catching in the harrow
teeth, or from being stepped on by the horses.
S, designates a seat for the driver; and;-U, an umbrella, extended over the same
to protect the driver from the intense heat of the sun, and the handle of this umbrella
is securely held in place in a socket, U.
S', and, S2, designate standards, rigidly secured to the central harrow section, H³,
and these standards, S', and, S2, are loosely fitted to, and extend through apertures, G,
formed in the sulky frame, F, as shown in Figs. 3, and, 5, of the accompanying
drawings, or these apertures may be formed in any suitable rigid support, for
the purpose of guiding the central harrow section,, vertically, as it is raised and
lowered, and thereby prevent the harrow sections or wheels of the sulky, from
being damaged, by striking against one another..
And secured to, or formed integral with the upper end of these standards, S1, S2,
are hooks, e, with which loops, e¹, on the handles, 1, engage, and these handles are
rigidly secured to the outer harrow sections, H', and, H³, so that by grasping the
handles, I, they, as well as the harrow sections secured thereto, may be elevated to the
position shown in Fig. 1, of the accompanying drawings, when passing through a gate,
or along the road, or from one field to another, or when in operation, one of the
outer sections may be raised as shown, to pass a stump, stone, or other obstruction, or
one harrow section may be raised, to remove a sod, or other large obstruction
from the teeth of the harrow.
And, J, J, designate braces, which further brace, and rigidly 'secure the central
harrow section to the standards, S', and, S³..
As shown in Fig. 2, L, designates a self-locking lever, formed with an arm, U,
and the latter is connected by chains, K, with the central harrow section, H2, as
shown in Fig. 2, of the accompanying drawings, and this lever is pivoted on a
pin, 13, secured in a bracket, 12, and the latter is secured to the sulky frame, F ;
when the lever, L, is in the position shown by solid line in Fig. 2. the central
harrow section, H', is lowered in position for working, because the arm, , is in
front, and underneath said lever, L, and when this lever, L, is in the position
shown by dotted line in Fig. 2, and the loops, e¹, on the handles, I, engage with
the hooks, e, on the standards, S1, S2, all of the harrow sections are raised clear
from the ground, to the position shown in Fig. 1, and the harrow. sections are
locked in this position because the arm, 1, on the lever, L, to which the chains, K,
are attached, is above, and at the rear of the pin, 13, on which the lever, L, is
pivoted.
;
And, T, designates a tongue, pivoted on the pivot bolt, t, secured in the frame, F;
this tongue is pivoted in this manner, to prevent it from jerking or striking the
horses, if one side of the sulky or harrow section should strike an obstruction
and, 3, designates a pin, which may be extended through the tongue, T, and
frame, F, so that the horses could control the machine, when travelling along the
road or from one field to another. And the rear end of this tongue is held in a
socket bracket, N, rigidly secured to the frame, F, and this socket bracket, permits
a lateral but no vertical movement therein, when the pin, t2, is removed, and the
movement of the tongue, T, in this slotted bracket, N, permits the horses to easily
turn the harrow, at the same time, the rear end of the tongue, T, engaging with
the interior face of the ends of the socket, in the bracket, N, prevent the horses
and harrow sections from coming in contact, thereby preventing damage to
either.

page_text: In the annexed drawings :—this harrow is shown with teeth, suitable for the
purpose of harrowing, but cultivator or scarifier teeth may be used in their place,
if desired, so that this machine could be used equally well as a Harrow, Scarifier,
or Cultivator.
Having thus described my Invention I claim :-
