In constructing a waggon in which the seat has no vertical adjust- >
ment nor means for rendering it rigid the front ends of the perches are
attached to the head block, which also forms the front hound, pivotted
to the front axle by the usual ring bolt. On the underside of the
waggon body, at or near each side, runs a metal bar. The front ends of
the two bars are curved downward and form eyes or loops, which are
slipped over the ends of the front hound, or they may be hinged to the
front hound. The rear ends of the said bars also form eyes or loops,
which are slipped over the ends of the rear hound, and this hound is!
supported upon one or more elliptic or other springs attached to the rear
axle.

By this arrangement of the support for the body, it will be seen that
the body cannot sag forward or backward as is generally the case, when
passing over gullies or other similar places..

page_text: and grant unto me, the said William Robert Lake, Her special licence
that I, the said William Robert Lake; my executors, administrators,
and assigns, or such others as I, the said William Robert, Lake; my
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS FOR SUPPORTING AND ADJUSTING THE SEATS AND PARTS, CONNECTED
THEREWITH IN SULKIES AND OTHER: VEHICLES," a communication to me from
abroad by Jesse Jenkins, Wheelwright, and Lambert Jenkins, Black-
smith, both of Maryland, United States of America, upon the condition
(amongst others) that I; the said William Robert Lake, my executors
or administrators, by, an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner, the same, was, to
be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar, months next; and immediately after the date.

NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawing forming a part of this Specification:-
This Invention relates to mounting and binging the seat frame in
such a manner, that it may be adjusted to suit the, height of the horse;
also to the conversion of a road sulky into a track sulky, the seat frame
being made to spring or be entirely rigid at pleasure; also to the com-
bination and arrangement of the parts for attaching and supporting the
seat of a waggon to the running gear thereof to allow of the springing
of the seat without sagging forward or backward.

a waggon; and Figure 5) is a rear elevation of the same tú vo minta jas
BA
In Figures 1, 2, and 3, A, A, are the carrying wheels; B is the axle;
and C, C, are the shafts. The latter may be attached in any suitable
manner to the axle, and curved upward therefrom.
T
A
P
The seat Dis supported, by a frame E, which is preferably of a horse-
shoe shape, and is hinged at each side to the cross bar, of the shafts by,
metallic slides a fitted vertically into guides 6, that are, so secured to the
said cross bar that they may be raised and lowered, and clamped when
adjusted by set screws c passing through holes in the guides and slides:
By these means the seat frame can be kept level by adjusting it to suit
the height of the horse, which is very advantageous in sulkies.
t
The seat frame is supported upon the axle B by, a cross bar G of.
the said seat frame, and the seat is arranged, just above the axle: 'By
this arrangement the seat frame is permitted to spring up and down,
without interfering with the shafts. The seat frame being hinged at
opposite points to the shafts is thereby braced laterally, so that it cannot
have the least side motion, while it is entirely free to spring up and
down. This method of supporting and bracing the seat frame enables
me to have it independent of the shafts, and to use in: connection, with
the said frame a single spring F parallel with the axle instead of one at
each end thereof.
The sulky has an easy spring seat adapted for travelling over-roads ;
but by a very simple device I can convert it into a track sulky, and
render it as effectual as if it were made without springs as required for
the track. I accomplish this 'object by an arm I 'so pivotted to the axle
as to be raised to a vertical position in order to 'lock it with the upper
cross bar G of the seat frame, and thus render the seat frame perfectly
rigid. In the example shown in the Drawing this, is done by forming a
screw. thread on the end of the said arm I to enter a female screw thread
in a short arm d on the seat frame, and for this purpose the locking arm
is also swivelled to be turned to screw and unscrew with the screw nut
of the seat frame. When unlocked from the spring as a road sulky: 'the
arın is turned down, as shown in Figure 3, and sustained by a hook..
.
Instead of a single central locking arm, each side of the seat frame
may be fastened to the axle by other convenient' means.

Figures 4 and 5 represent a waggon in which the seat has no vertical.

axle and B, B, are the perches attached to the same. The front ends of
the said perchés. B, B, are attached to the head block C, which also
forms the front hound pivotted to the front axle A by the usual king
bolt. D represents the waggon body, on the under side of which, at or
near each side, runs a metál bar E. The front ends of the two bars E, E,
are curved-downward, as shown in Figure 4, and form eyes or loops,
which are slipped over the ends of the front hound C₁, or they may be
hinged to the front thound! The rear ends of the said bars E, E, also 1
form eyes or loops, which are slipped over the ends of the rear hound C,
and this hound is supported upon one or more elliptic or other springs G
attached to the rear axle A. i.
