page_text: Securing Railway Rails to Chairs or Sleepers.
I GEORGE WELLS of 12 North Street in the City of Westminster Civil
Engineer do hereby declare the nature of my said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The object of my Invention is to prevent the Keys by which rails are secured to
Chairs or Sleepers from being displaced either through the effect of weather or
from vibration caused by traffic.
The accompanying drawing is intended to illustrate my Invention with several
forms of Keys and the method of securing the Key to the Chair to prevent any
displacement of same.
Fig. 1. is an elevation of Chair and section of Rail with one form of Steel Elastic
Key fitted in recess of Chair ready to be screwed up to the Rail to rigidly secure
same to the Chair.
Fig. 2. is a plan of same.
Fig. 3. is another plan of same shewing the Key screwed up to its work and so
rigidly securing the rail to the Chair.
Fig. 4. is a plan similar to Fig. 3 shewing another form of Key.
Fig. 5 is another plan without a recess in the Chair to secure the Key, the Key
having a recess fitting a projection in the Chair to prevent its moving longitudinally
or being displaced by any vibration.
Fig. 6 is an elevation of another form of Chair and section of rail with Key-
The Key being placed or slipped in the Chair longitudinally; the Key having a
recess or recesses in which the Screw bolt or bolts fit, so that when the Key is
screwed up to its work it cannot move longitudinally.
Fig. 7 is another elevation, the Chair being similar to that shewn by Fig. 6. the
Key however being of another shape or form.
Fig. 8 is a plan of Figs. 6 and 7.
Fig. 9 is a plan of another form of Key with web of rail, the Key being shewn
as if screwed up to its work, the Chair to be used being the same as shewn by
Fig. 1.
Fig. 10 is a section of another form of Key with section of rail the Key being
shewn as if screwed up to its work, the Chair to be used being the same as shewn
by Fig. 7.

page_text: A is the Chair-B the Rail-C the Key-D recess in the Chair in which the
Key is placed-E the Bolts for screwing the Key up to its work F-Fig. 5 is a
projection on the Chair fitting into a recess in the Key so as to prevent the Key
moving. longitudinally-G is a recess made in the Keys, when chairs similar to
those shewn by Figs. 6. 7 and 8 are used to prevent the Keys moving longi-
tudinally.
It will be seen by reference to the drawing that it is impossible for the keys to
be subject to any longitudinal movement and it is only necessary to keep the Bolt
tightly screwed against the Key to rigidly secure the Rail to the Chair.
This Invention also applies to securing Rails to Metal Sleepers without Chairs,
the projection on the Chair for holding the Key against the Rails having a Screw
Bolt or Bolts as described and shewn for keeping the Key up to its work and
rigidly securing the rail to its sleeper and prevent its moving longitudinally or
being displaced by vibration and it also applies to securing Keys to the present
form or forms of Chairs by using a Screw Bolt or Bolts as described and shewn
for keeping the Key up to its work and rigidly securing the Rail to the Chair and
prevent its moving longitudinally or being displaced by vibration, in both instances
there must be recesses in the Keys into which the Screw Bolt or bolts fit.
I wish it to be understood that I do not confine myself to any particular form of
Key, which may be elastic solid or rigid, nor to the form of Chair, nor sleeper.
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. Making a recess in the Chair as shewn by Figs. 1 to 4 into which the
Key is fitted and so prevent its being displaced by vibration or otherwise.
Secondly. Making a deep recess in the Key as shewn by Fig. 5 into which a
projection cast on the Chair fits, which prevents the Key being displaced or moving
longitudinally.
Thirdly. Making a recess in the Chair as shewn by Figs. 6 to 8 into which the
Key is slipped longitudinally-The Key having a recess or recesses into which the
Screw Bolt or bolts fit as shewn by Figs. 6. 7. 8 and 10. The recess or recesses in
the Key prevent its moving longitudinally after it is screwed up to its work.
Fourthly. The application of the Screw bolt or bolts as above described for
keeping the Key up to its work and rigidly securing the rail to the Chair or
Chairs as shewn and described or to the ordinary Chair or Chairs or to any
projection on a Metal Sleeper which acts as a substitute for a Chair.
