page_text: We JAMES HONIBALL TOZER and WILLIAM TOZER, of 18 Abingdon Street, in the
City of Westminster, Railway Plant Contractors do hereby declare the nature of
this invention to be as follows:-
Our invention has reference to securing railway chairs to metallic sleepers.
For this purpose we make the chair, which may be of wrought iron or steel,
with one or more flanged holes and we make the sleeper with corresponding
holes. We pass the flanges of the holes in the chair into the holes of the sleeper
and we then rivet or press over the said flanges against the underside of the
sleeper; or we pass rivets through the flanged holes and rivet them against the
underside of the sleeper in which case the flanges must not project through the holes
of the sleeper, or we both rivet or press over the flanges against the underside of
the sleeper and insert rivets through the flanged holes rivetting them under the
rivetted or pressed over flanges.
The flanged holes may be formed in the chair by means of presses or otherwise.
The flanged holes will generally be made in flat portions of the chair, and the
configuration of the chair and its jaws will depend upon the section of the rail to
be secured therein, whether flat bottomed, bull headed or otherwise.

page_text: Improvements in Securing Railway Chairs to Metallic Sleepers.
We JAMES HONIBALL TOZER and WILLIAM TOZER, of 18.Abingdon Street, in the
City of Westminster, Railway Plant Contractors 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 object of our invention is to provide more efficient means of securing railway
chairs to metallic sleepers. With this object we make the chair, which may be of
wrought iron or steel, with one or more holes, flanged on the underside and we
make the sleeper with corresponding but unflanged holes which the flanges on the
chair will fit. We pass the flanges of the chair into, or through the corresponding
holes in the sleeper and then secure the parts together by rivetting.
This rivetting may be effected in several ways. According to the preferred way
we make the flanges of the flanged holes in the chair long enough to project some
distance beyond the holes in the sleeper; we rivet or press over the projecting part
against the underside of the sleeper and we finally insert rivets through the
flanged holes and rivet these rivets over upon the rivetted or pressed over flanges,
the rivet heads bearing upon the top of the chair. According to another way the
flanges of the flanged holes in the chair are not made long enough to project
beyond the holes in the sleeper and in this case after inserting the flanges we pass
rivets through the flanged holes and rivet these rivets against the underside of the
sleeper, their heads bearing upon the chair as in the first way. According to
another way we dispense with separate rivets and secure the parts together by
merely rivetting or pressing over the projecting part of the flanges against the
underside of the sleepers as in the first way.
The flanged holes may be formed in the chair by means of presses or otherwise.
The holes will generally be made in flat portions of the chair and the configuration
of the chair and its jaws will depend upon the section of the rail to be secured
therein, whether fat bottomed, bull headed or other sections.
It is obvious that the position of the flanges may be reversed, that is to say :-
the holes in the sleeper may be flanged at their upper side and the chair have
corresponding unflanged holes to receive the flanges on the sleeper.
In cases where' instead of an entire chair being used there are part chairs in the
form of clips to act as chair jaws the rail having its seat directly upon tha sleeper
itself, or upon a pad or layer of felt or other material laid thereon, we secure these
part chairs or clips to the sleepers precisely in the manner above described in
respect of entire chairs.
In the accompanying drawings Figures 1 and 2 are vertical sections illustrating
the preferred way of carrying out our invention as applied to chairs suitable to
receive bull headed and flat bottomed rails respectively. a is the sleeper made
with plain or unflanged holes at b, b; c is the chair formed with corresponding
holes at d, d, these holes being formed with flanges e, e which fit the holes b, b.
After passing the flanges e, e into the holes b, b the portions of the flanges that
project beyond these holes are rivetted or pressed over against the underside of
the sleeper, as seen at f, f. 9. g are rivets which are then passed through the

page_text: flanged holes and rivetted over against the rivetted or pressed over parts f,f of the
flanges e, e, their heads bearing upon the top of the chair, as shown.
Figure 3 illustrates the modification in which the flanges e, e are not long enough
to project beyond the corresponding holes b, b. In this case after passing the
flanges e, e into the holes b, 6 the rivets g, g are inserted and rivetted over against
the underside of the sleeper.
Figure 4 illustrates the modification in which no separate rivets are employed.
In this case the chair is secured to the sleeper by merely rivetting or pressing over
the projecting part of the flanges e, e against the underside of the sleeper, as seen
at t, f.
Figure 5 illustrates a modification in which the flange is reversed, that is to say:
in which the sleeper has flanged holes to enter plain or unflanged holes in the
chair. No separate rivets are shown in this figure but of course they can be used
if desired.
For convenience of manufacturing the chairs, particularly those having jaws
(such as seen in Figure 1) to receive bull headed or double headed rails, they may
be formed in two pieces each piece carrying one jaw. The pieces, when in place
on the sleeper, would meet preferably below the seat for the rail, as indicated by
the dotted line h in Figure 1.
Figure 6 illustrates the application of our invention to securing part chairs or
clips to sleepers. c is the clip or part chair formed with a hole d, with flange e
which is passed through the corresponding hole b in the sleeper a, and then rivetted
over as at f, after which a rivet g is passed through the hole d and rivetted over
the part f. c¹is the clip or part chair for the other side of the rail; it may be
secured either by a bolt and nut as shown, or in any other usual manner, or by
the same means as the clip c, in which latter case one side of the rail would be
fixed by a key driven in between it and one of the clips.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. As means of securing railway chairs or part chairs to metallic sleepers, one or
more flanged holes in the chair or part chair and corresponding unflanged holes in
the sleeper (or vice versa) the flanges of said flanged holes being inserted into said
unflanged holes and the parts being then secured by rivetting substantially as
set forth.
2. The several means or arrangements hereinbefore described and represented in
the Figures 1 to 5 for securing chairs or part chairs to metallic sleepers.
