We WILLIAM STEVENS, of 56 Lenthorpe Road, East Greenwich, S.E, Engineer,
and JOHN PEACE, of 2 Osborn Terrace, Westcombe Park, Blackheath, S.E., Engineer,
do hereby declare the nature of this invention to be as follows:-
The chair is made with one jaw fixed and the other hinged. The latter jaw is
somewhat of a bell crank form, a part of which supports the bottom of the rail
thereby holding the other part firm against the rail, consequently pressing the rail
against the fixed jaw. This hinged jaw works on a steel pin held in chair, the eye
in jaw for the pin to pass through being slotted to facilitate the removal and setting
of the nail. A portion of this slotted eye is cut out to admit of the jaw being
removed without taking out the steel pin. Either of the jaws can be arranged to
hold a wooden key, a portion of which can be let into the inside of jaw to retain
the key.

page_text: We WILLIAM STEVENS, of 56 Lenthorp Road, East Greenwich, S.E., Engineer,
and JOHN PEACE, of 2 Osborne Terrace, Westcombe Park, Blackheath, S.E., 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 chair according to this invention is made with one jaw fixed and the other
hinged, the form of the latter being such, that the rail is automatically locked by the
weight of the train. The eye of the hinge is made elongated and opened at bottom
whereby great facility is afforded for the removal and introduction of the rail, and
of the hinged jaw part.
To enable our invention to be properly understood 1. will proceed to describe the
same with aid of the accompanying drawings.
Figure 1, side elevation of chair with rail secured.
Figure 2, plan of same at line X, Y.
Figure 3, sectional elevation with hinged jaw open, at line X, Y¹, figure 2.
A, is the bed, which is preferred to have four holes for securing it to sleeper, B,
the fixed jaw, which is cast with A, C the hinged jaw, formed with a support D,
for the bottom of rail to rest upon; this jaw is hinged in bed A by a cross steel pin E.
The eye of the jaw is made elongated as shown in drawing to facilitate the removal
of rail and its introduction into chair. At the bottom of the eye a space is cut out
sufficient to allow the jaw to be lifted out of chair without withdrawing the pin E.
The fixed jaw B, has a depression formed on its inside to enable a wooden key F,
to be held, such key being made with a suitable projection to. enter the depression.
If desired a similar key may be used with the hinged jaw. When the rail is held
in chair as at figure 1, it will be readily seen that the greater the weight on rail,
will cause it to be held the tighter against fixed jaw B. To remove the rail, the
jaw C, is pulled up until the end of the elongated eye meets the pin E, when the jaw
and rail are then turned over when the pin E gradually works back to the other end
of the elongated eye as at figure 3. A portion of the bottom of this eye is cut out
to enable the jaw to be removed from chair without withdrawing the pin E.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
.'
1. The improved construction of chair for rails, substantially as described and
illustrated in the accompanying drawings.
2. The mode of securing rails in chairs by having one jaw fixed and the other
hinged with a supporting portion for the rail to rest upon by which the rail is pressed

page_text: against the fixed jaw by the hinged jaw, substantially as described and illustrated in
the accompanying drawing.
3. In a chair for rails having one jaw fixed and the other hinged, the use of an
elongated eye for the hinged jaw, as and for the purposes described.
4. In a chair for rails having one jaw fixed and the other hinged by an elongated
eye, the use of the opening in the bottom of the elongated eye to enable the jaw to
be removed from chair without withdrawing pin E.
