PROVISIONAL SPECIFICATION.
Improvements in the Construction of Seats, applicable to Cycles,
Railway Carriages, Tramcars, and other Vehicles.
I, JAMES JOSEPHI DUFFY, of Carrickmacross, County Monaghan, Ireland,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention has reference to improvements in the construction of seats
applicable to cycles, railway carriages, tramcars, and other vehicles, for the purpose
of obviating concussion, and reducing vibration to a minimum.
My invention consists essentially in the arrangement of spiral or helical springs
either alone or in combination with the flat or other ordinary springs at present
employed.
In the case of seats for cycles, I propose to use three, spiral or helical springs
(one in front and two at back) which are suspended from the members of the
ordinary springs at present used, and from these spiral or helical springs is
suspended the seat or saddle by means of curved stay rods.
Thus according to my invention the seat is carried by a combination of the
ordinary springs, and the spiral or helical springs constituting the feature of my
invention.
In applying my invention to. railway or tramway seats, or seats of such like
vehicles I propose to arrange a second floor in addition to the ordinary floor, and
in the space between I fix any suitable number of spiral or helical springs so that
the seats built upon the proposed second or upper floor will be mounted on a floor
or foundation partaking of a springy or elastic character. Or instead of the
present ordinary floor I may mount the spiral or helical springs on suitable frame-
work, thus using only one my proposed floor for carrying the seats.
By this arrangement an elasticity in the construction or mounting of seats is
obtained which cannot possibly be acquired by any method of arrangement or
construction hitherto in use..

Improvements in the Construction of Seats, applicable to Cycles;
Railway Carriages, Tramcars, and other Vehicles.
I, JAMES JOSEPH DUFFY, of Carrickmacross, County Monaghan, Ireland,
Merchant, 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 has reference to improvements in the construction of seats
applicable to cycles, railway carriages, tramcars, and other vehicles for the purpose
of obviating concussion and reducing vibration to a minimum.]

page_text: The invention consists essentially in the arrangement of spiral or helical springs
either alone or in combination with the flat or other ordinary springs at present
employed.
The accompanying drawings will enable my said invention to be more readily
understood and carried into practice.
Fig. 1, illustrates the application of my invention to an ordinary cycle seat.
a, a, are the ordinary springs on which the seat b, is mounted.c, c, are the spiral
springs the use of which in the manner herein described constitutes the essential
feature of my invention.
These springs are made of a suitable strength and number of convolutions
according to requirements, and are provided at each end with a disc c' which is
threaded round its periphery so as to screw into the end convolutions. Through
the centre of these discs are sorewed the threaded bolts whereby the spirals are
secured as shew.n..
By this arrangement it will be obvious that the seat is carried by a combination
of the ordinary, and the spiral springs, and that the latter are used on the suspension
principle, that is.to say, they are placed so as to be expanded by weight instead
of being compressed as is usual according to the present practice of using same.
And this is the principle which I desire it to be understood I claim as my
invention.
Fig. 2, illustrates the application of my invention to seats for railway carriages,
tramcars, and such like vehicles. d, d, is the top floor on which the seat is arranged,
or the floor itself may constitute the seat.
Underneath is erected the floor e, e, which is supported by the posts ff, and
from which the top floor or seat is supported by means of the brackets
spiral springs h, h, as shewn.
9, 9, and
Or instead of using the floor e, e, a simple bar or frame -Eig. 3-may be
employed from which the top floor or seat is suspended by double brackets k, and
spiral springs k', as illustrated.
'
By the arrangement herein described it is obvious that an elasticity in the
construction and mounting of seats is obtained which cannot be afforded by any
method hitherto in use.
Although I have only shewn and illustrated the application of my invention to
the seats of cycles and railway carriages and tramcars, it is obvious that the
principle involved may readily be utilized in a modified form in connection with all
kinds of vehicles where it is desirable to reduce vibration.
Thus portable seats may readily be constructed according to my invention for
use on ordinary carts, such as delivery vans, market carts, and such like; and
furthermore a portable platform may be similarly constructed for the use of engine
drivers, and stokers on the ordinary locomotive. This latter application would
tend to reduce considerably the incouvenience usually experienced owing to the
vibration of railway locomotives when running at high speeds.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
T
In the construction of seats for cycles, railway carriages, tramcars, and such like
vehicles, the use and application of spiral or helical springs separately, or in
combination with ordinary springs in the manner substantially as herein specified
and set forth.
