invention for "IMPROVEMENTS IN CARRIAGE SPRINGS AND THEIR APPURTENANCES
to be as follows:-
"
This invention has for its object carriage bow springs somewhat similar to an
ordinary eliptic spring which shall give the ease and swinging effect of a C spring
without its stiffness, cost and extra weight. It consists in causing the one half
spring to pass through the other near each end, making one of the half springs
much longer than the other, and connecting each of the ends of the halves to
those of the other by a brace. These braces, being at an angle like the brace of,
a C spring, change an upward jerk of the wheel into a combined vertical and;
horizontal motion of the carriage body in the same manner as the C spring
arrangement does, thus taking off the lateral thrust to a great degree. The way
I prefer to arrange the half springs so as to pass the one through the other is to
form three bows, two top and one bottom one, or two bottom ones and one top, the
single bow passing upward or downward between the two passing in reverse
direction. The two parallel bows have a pin through their eyes and are separated
by two bobbins or collars and a ferrule on the bolt between them. The brace
passes round this ferrule and another similar ferrule on the bolt of the upper spring.
The ferrule is useful to increase the bearing for the brace, take the wear off the
bolt, and separate the two collars or bobbins. The collars and ferrule can however
be formed solid with the pin as a single piece.

page_text: I, GEORGE SIMMONS of 16a Colquitt Street, Liverpool in the county of Lancaster,
Carriage Builder do hereby declare the nature of my said invention for "IMPROVE-
MENTS IN CARRIAGE SPRINGS, AND THEIR APPURTENANCES," and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention has for its object carriage bow springs somewhat similar to an
ordinary eliptic spring which will give the ease and swinging effect of a C spring
without its stiffness, cost and extra weight.
It is best described by aid of the accompanying drawings which are given as an
illustration of the best mode known to me (for general purposes, of carrying this
invention into effect. In these Figure 1 is a side view. Figure 2 plan partly, in
_section of the apparatus. The invention consists mainly in causing the one half
spring (A) to pass through the other, half spring B B near each end, making one of
the half springs much longer than the other, and connecting each of the ends of the
halves to those of the other by a brace C. These braces being at an angle like the
brace of a C spring, change an upward jerk of the wheel into a combined vertical
and horizontal notion of the carriage body in the same manner as the C spring
arrangement does, thus taking off the lateral thrust to a great degree.
In the upper half spring A is shown passing between the two halves of the other
thus forming three bows, one top and two bottom, but the reverse could be.
employed, namely two top bows and one bottom one, the top one in all cases being
the longer. The two parallel bows have a pin D through-their-eyes and are
separated by a flanged-ferrule E or two bobbins with a plain ferrule between round
the bolt. The brace is formed of one or more leather bands or their equivalent F F
in the drawing. This brace passes round ferrule E between the flanges or bobbins
as the case may be, and then round another similar ferrule G, on the bolt H of the
upper spring A which is however the lowest at this point.
The ferrules are useful to increase the bearing for the brace, to take the wear off
the bolt, and to separate the two collars or bobbins. The collars and ferrule can
however be formed solid with the pin as a single piece of turning, but the wear on
the brace will be much greater in this case. The two pins or spindles at each end
are formed with nuts or heads and nuts as shown, and round each end of the brace
I place a covering J of sheet metal or other suitable material to save the brace
from wear.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. The manufacture of carriage springs and their appurtenances, substantially
as described, in which one of the two half springs pass through or between the
part of the other half, and is connected with the latter at each end by braces.

page_text: 2nd. The combination of the springs A and B with the braces F and the pins D
and ferrules E or their mechanical equivalent or substitute, substantially as
described.
