Improvements in Rail Chairs and Couplings for Permanent Ways.
We, ROBERT CARDWELL, of 11, Vivian Street, Liverpool, Moulder, and
SAMUEL WATSON, of Lime Bank Street, Ardwick, Manchester, Railway Clerk,
both in the County of Lancaster, 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:-
Our invention relates to improvements in rail chairs and couplings for permanent
ways for which Letters Patent No. 8176 and dated June, 5th 1888 were granted to
us and in which invention the rail in its continuity or at its ends is secured
respectively either to a single or joint chair, by means of a hinged jaw in com-
bination with a metal wedge driven between the same and projections formed on
the base of the chair.
:
The object of our invention is to render the said hinged jaw readily detachable
and thereby facilitate the placing and removal of the rail or rails on or from the
chair whilst at the same time the hinged jaw is prevented from becoming fast
through corrosion and will adjust itself against and thus hold the rail more firmly
than heretofore has been the case.
And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a side view and Fig. 2 a plan of a rail chair constructed in accordance
with our invention and adapted to be secured to a sleeper. Fig. 3 is a sectional
side view and Fig. 4 a plan of a chair with rail and hinged jaw removed. Figs. 5
& 6 are respectively a side view and back view of the hinged jaw itself detached.
In carrying out our invention and referring to the figures generally, we dispense
with the bolt used heretofore to secure the movable jaw a to the base 6 of the chair
and form the movable jaw a at each end with a pivot c, see more particularly
Figs. 5 & 6, preferably by casting a metal pin into the same, the ends of which
project on each side thereof. The eyes d we form solid and the inner sides with a
sloted socket e, el adapted to receive the pivots c of the movable jaw a when placed
between the eyes d thus forming a slot hinge. The wedge g placed between the
projections or noses f,f when driven home, forces the movable jaw a bodily against
the side of the rail and when withdrawn the jaw a may be readily removed by
throwing back and lifting it out of the socket e through slot e¹.
It will be understood that the improvements described are applicable for single
as well as joint chairs, either secured to or formed with a sleeper.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is-
In single and joint rail chairs, secured to or formed with a sleeper, the movable
jaw a having pivots c in combination with the eyes d formed on the base b, the
inner faces of which are formed with slotted sockets e, e¹, adapted to receive the
pivots c and serve as a fulcrum for the movable jaw a, substantially as and for
the purpose set forth.
