Improved Means for Preventing or Lessening Jolting in Passenger
and other Vehicles including Cycles.
I, Neil Lêitch, Watchmaker and Jeweller, residing at No. 2, Francis Street,
Pulteneytown, Wick, in the County of Caithness, do hereby declaro the nature
of this invention to be as follows:-
My invention relates to improvements in passenger and other conveyances,
including cycles, and has for its object the prevention or lessening of jolting of
vehicle while in motion.
The
My said invention consists in an open or encased spiral or other spring of a
similar nature, or of elastic bands or springs, having a strong contracting or
downward pull from the body of vehicle to the axle. One or more of these springs
or bands will be attached to each side of conveyance (and also in centre or any
other part if necessary) and fixed at the lower end to axle, at a point either inside
or outside ordinary springs of vehicle, according to construction of same.
upper end of spring will be attached to body of conveyance or shafts, by a fixed
eye, or au oye with a swivel. A threaded rod may connect swivel and spring,
and the turning of the rod will weaken or strengthen the downward pull of spring,
or otherwise, increase or diminish the distance between the body of vehicle and
axle, according to load.

In a similar manner but on a smaller scale, the invention can be attached
between the seats and body of cycles, with the same object:

Improved Means for Preventing or Lessening Jolting in Passenger

of Caithness, Watchmaker and Jeweller, do hereby declare the nature of this.
invention and in what manner the same is to be porformed, to be particularly
described and ascertained in and by the following statement:
My invention relates to improved means for preventing or lessening jolting
in passenger and other vehicles, including cycles, and consists in the application
of an open or encased spiral or other spring of a similar nature or elastic bands
or springs of one or more coils all of which are of simple mechanism, and will

page_text: have a strong contracting or downward pull from the body of vehicle to the axle.
One or more of these springs may be placed between the ordinary springs of
vehicle, or may be attached to each side and also to centre of conveyance if found
necessary, and fixed at lower end to axle, either inside or outside ordinary springs,
and at the upper end, to body of vehicle, or shafts, or both, or any other more
suitable part, according to construction of vehicle or cycle.
In order that my invention may be clearly rendered, reference may be had
to the accompanying sheets of drawings in which Fig. 1, is a front view, shewing
internal construction of an encased spiral spring, the encasement being in two
parts the upper overlapping the lower part. Similar letters of reference are
used to indicate like parts in all the drawings.
A, is the axle of vehicle, and B B B is a clasp going round same, and fixed
below by sorew bolt C C. The rod D ) is fixed on top of clasp, and enters lower
encasement by a hole in centre-passing upwards on inside of spiral spring as
shewn. On any weight being applied to vehicle, either by passengers or otherwise,
the effect is to bring the body nearer the axle, thereby causing the rod D D to
be pushed upwards, or more correctly, the encasement will be forced downwards
on rod and its action is automatic. The notches in the rod D D as seen more
clearly in Fig. 2, which is a side view of same spring but with a different attach-
ment at top, are received by the edge of two small plates, connected to the small
springs EE which are fully shewn in Figs. 3 & 4. Whatever distance there-
fore the rod DD passes upwards, the same is held and maintained by this con-
trivance, and any heave or jolt of vehicle is immediately met and resisted by
the full strength of spiral spring. In connection with the small springs E E
already referred to, is a pinion g, which is mounted with two graduated
circles FF and by applying the key l'ig. 5, to end of pinion g, and turning same,
the two springs E E are compressed-thus liberating the rod D D and allow-
ing the vehicle when not in use to return to its normal condition.
Fig. 6, is also an encased spring, the encasement being also in two parts, but
it does not act automatically. The swivel and threaded rod are one piece, and on
turning the swivel (either with hand or otherwise) the rod is screwed into a
threaded hole in end of encasement as shewn, and the distance between the body
and axle of vehicle is thus regulated according to load.
Fig. 7, is another encased spring, but encasement is whole and in one piece.
In this case only one end of spiral spring is fixed to encasement-the other end
of spring as shewn is fixed to end of rod D 1 by means of a shoulder. A hole
in swivel is threaded to receive the other end of rod D D which is also threaded,
and by screwing down swivel on rod, the distance between vehicle and axle can
be adjusted to load, as in Fig. 6. A heave or jolt will compress this spring. Fig. 8,
is a plain open double conical spring, and the attachment both above and below
is shewn in drawing. Fig. 9, is an elastic band set on pulleys at both ends, and
Fig. 10, is a steel spring of C shape. Either Figs. 8, 9, or 10, can be applied to
ordinary vehicles but may be more suitable for cycles, and can be attached between
the seat and framework, or in connecting any other two or more parts of machine
according to construction of same.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
First. That by the application of spiral or other springs, of a similar nature,
or elastic bands or springs, fitted or attached between the body and axle of vehicles
and cycles, a resistive force is obtained, sufficient to prevent or lessen jolting, sub-
stantially as herein described and shewn.
Second. That in passenger and other vehicles including cycles, the application
of one or more spiral or other springs of a similar nature, or elastic bands or
springs, fitted and attached between the body and axle, or any other more suit-
able part of vehicle or cycle-a resistive force is obtained, which will prevent or
