COMPLETE SPECIFICATION.
An Apparatus to Receive the Blows of Impact or Concussion which
Occur when Levers or other Contrivances are Desired to be Put
into Motion by Railway Trains or other Moving Bodies.
I FREDERICK NOWELL of 193 Askew Road in the County of London
Engineer 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 :-
The invention consists of having a loose weight preferably in the shape of a
loose ring,
or a loose disc, which on being struck by coming into contact with an
obstruction, will be driven into a chamber or guide, and in which it will expend
the force of the blow.
With this Specification are 3 sheets of drawings illustrating its application when
supplemented to levers.
In Sheet No. 1 the plate a bed is assumed to be part of an engine or machine
moving in the direction of the arrows. To the plate abcd a lever is fixed on the
study and it bifurcates at h so as to pass on each side of the disc-chamber i.
A spring is fixed to one end of the lever and to the plate a b c d at the other end.
The disc-chamber i is fixed to the plate a b c d and it will allow of the free passage
of the disc. The disc f has a spindle so as it will rest on the bifurcated arm of
the lever. When the disc f (which is quite detached) meets the obstruction e it is
driven into the disc-chamber i, and the lever being relieved of the weight is pulled
upwards by the spring k. The disc f expends the force of the blow in the disc
chamber and then rolls back on to the lever. The lever is actuated only by the
spring, however small or great the blow may be that is given to the disc f.
In Sheet No. 2 the plate a bed is assumed to be part of an engine or machine
moving in the direction of the arrows. To the plate a bed a lever is fixed on the
study and it bifurcates at h so as to pass on each side of the disc-chamber. The
disc-chamber is fixed to the plate a bed and it will allow of the free passage of
the disc. The disc bas-a spinile so as it will rest on the bifurcated arm of the
lever and it also will rest upon rollers m m fitted between the bifurcated arm of
the lever. When the disc (which is quite detached) meets the obstruction e it
is driven into the disc-cbamber i and the lever being relieved of that weight falls
downwards by the force of gravity. The disc expends the force of the blow in
the disc-chamber i and then rolls back on to the lever.
The lever is actuated by gravity alone, however small or great the blow may be
that is given to the disc f.
In Sheet No. 3 the plate abis assumed to be part of an engine or machine
moving in the direction of the arrows, and to this plate a lever is attached by the
stud c.
The arm of the lever bifurcates at d so that the disc-chamber can be
fixed to it. The ring or disc i rests on rollers k k fitted between the bifurcated
arm of the lever. When the disc i (which is quite detached) meets the obstruction
it is driven into the disc-chamber and the lever being relieved of that weight is
put into motion first by means of gravity and secondly by means of the blow given
by the disc i to the disc-chamber f
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is
An apparatus to receive the blows of impact or concussion which occur when

page_text: levers or other contrivances are required to be put into motion by railway trains
or other moving objects and which apparatus consists in having a loose weight
preferably in the shape of a ring or of a disc which on being struck by coming
into contact with an obstruction will be driven into a chamber or guide in which
it will expend the force of the blow.
