PROVISIONAL SPECIFICATION.
Improvements in Two-wheeled Vehicles.
I, JOHN PITT BAYLY, of 18 Fulham Place Paddington, in the County of
London, Patent Agent, (a communication to me from abroad by John Terman, of
Mansfield, Ohio, U.S.A., Dealer in Agricultural Implements,) do hereby declare
the nature of this invention to be as follows :-
This invention has for its object to provide greater comfort in travelling in two-
wheeled vehicles, and to reduce the jolting occasioned by rough roads.
By this invention, two springs are arranged upon the axle, one on each side of
the body of the vehicle respectively. The upper part of these springs are con-
nected by a cross-bar which extends across the vehicle. These side-springs are
connected to the body of the vehicle by flexible or universal link connections.
These flexible connections may be secured to curved bars which are either formed
integral with or secured to the springs. The shafts are also connected by flexible
connections to the body of the vehicle.
By this construction the body of the vehicle is suspended away from the
axle and shafts and the weigh of the body must pass entirely through the
springs.

COMPLETE SECIFICATION.
Improvements in Two-wheeled Vehicles.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by John Terman, of Mansfield, Ohio, U.S.A.
Dealer in Agricultural Implements,) to be as follows:-
My invention relates to improvements in two-wheeled vehicles, and the objects of
my invention are, first, to provide means to obviate all jerking movement caused by
the motion of the horse, which is termed "horse motion," second, to provide a two-
wheeled vehicle that will be as easy in motion as a four-wheeled vehicle, at the
same time to be durable and cheap in construction. I attain these objects by the
mechanism illustrated in the accompanying drawings, in which-
Fig. 1 is an end view of a two-wheeled vehicle, showing one end of my
invention.
.
Fig. 2 is a top view of the vehicle as it appears when the two wheels, the shafts
and body are removed.
Fig. 3 is a vertical side view showing the mode of attaching the springs, also
their construction.
Similar letters refer to similar parts throughout the several views.
In the accompanying drawings A indicates a single axle upon which is mounted
the elliptical springs B and B. Said springs are secured to the axle by means of
clips L. Secured upon the upper arch of the elliptic springs B and B₁ are the
inverted curved bars E, said bars having eyes F formed upon each end, and in
which is placed the hinged pivot-bolt H, and held in position by the nut G, said
bolt having a pivot-movement in the eye E.
I indicates a link or hinged rod having hinges at each end.
C is a bar which extends from one link to the one on the opposite sides, which

page_text: makes a connection between spring B and B¹. I place one of the said hinged con-
nections in each end of the curved plate E, as shown in Fig. 2.
D is a brace which extends from spring B to B. The object of the said brace
is for the purpose of retaining the springs in a perpendicular position. The said
brace is secured to the inner arch of the upper portion of the springs B and B' by
the clips K, which hold in position the inverted curved plate E, as shown in Figs. 1
and 2. The bed N is secured to the bars C and C¹, the bed resting upon the said
bars, and is held in position by kalf-boxes secured on the under side of the bed.
The front part of the bed is secured to the cross-bar R which connect the shafts O
together by means of straps S, but may be suspended by means of a connection
having ball-joints. The bars C and C¹ can be constructed with ball-joints in the
place of hinges. In that case the bar C could be flat and secured rigidly to the
under side of the bed.
It will be readily seen that when the bed is secured in position, as shown in
Figs. 1 and 3, the link, or hinged connections, allow the bed N to reciprocate in any
direction, giving an easy motion to the bed, and obviating all jerk motion common
in all other two-wheeled vehicles now in use.
I do not wish to limit myself to the exact construction shown. Changes could
be made which would not depart from the essence of the invention.
Having now particularly described and ascerted the nature of my said inven-
tion, and in what manner the same is to be
claim is :-
