COMPLETE SPECIFICATION.
An Improved Bolt for Rails used in Points and Crossings, and
the like.
We JOHN TAYLOR of Foxhall Road Nottingham Engineer and JOHN TAYLOR
& SONS LD. of Queens Road Nottingham Engineers 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 has for its object to provide means of readily screwing up &
unscrewing the nuts used with bolts, studs, and the like, and at the same time
keeping the bolt or the like stationery.
The usual way of tightening up and unscrewing the nuts from bolts is performed
by using two spanners or wrenches, one for the object of preventing the bolt
turning round, the other for turning the nut, or forming square holes in the rails
and using square neck bolts.
Our improved bolt, stud or the like is so made that the nut can be screwed on
and off without extra spanner or square holes in the rails, and for the crossing
fastening we make a round neck bolt similar to ordinary ones but with a special
head, square, oblong or the like in shape of required dimensions, two edges being
bevelled to fit between the flanges of the rail, similar to fishplates used on
permanent ways, thus when screwing on or off the bevel edges beat hard upon the
inuer flanges or heads of the rail and by reason of its form it is impossible to turn
round, and thus the nut may be screwed on and off with one spanner.
For securing the stock or side rail to its chair, the bolt, stud, or the like is formed
after same manner, but with boss or projection on the head proper of the bolt, the
boss or projection being made in length to suit required travel of switch rail when
thrown in work.
Our bolts, studs and the like may be applied to any section rail used on railways
or the like.
We will now proceed to describe our invention with reference to the accompanying
drawings of which
Figures 1, 2 & 3 represent respectively front and two end views of our bolt used
for securing rails together near nose of crossing.
Figures 4 & 5 are respectively front & end views of stud or bolt used for
securing stock rail in points or switches.
Figure 6 represents section made near end of nose of a crossing, showing the two
rails secured by bolt similar to Fig. 1.
Figure 7 is a section showing stock rail for switch secured to slide chair by
stud or bolt similar to Fig. 4.
The drawings show in both cases bulb headed rails but our bolts and studs can
be applied to flat bottom or other section rails used for permanent ways and
the like.
Referring to Figures, 1, 2 & 3 & 6, A represents bolt used for crossings, which
has a special formed head a, with two bevelled edges & b', bearing hard upon
faces & 3 of rail C as in Fig. 6 prevents the bolt turning and allows the splice
rail D to close up to rail C.
Referring to Figs. 4, 5 & 7 E represents stud or the like used for points or
switches, which has in addition to that shown Fig. 1 a boss or projection c on head
proper and made of necessary dimensions and for acting as a stop for switch rail
to work up to. Figure 7 shows rail bolted to slide chair H by bolt or stud made

page_text: after manner of Figures 4 & 5, so that when screwing nut F the edges & b¹ bear
hard upon 62 & 63 and thus prevents bolt turning round.
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
1st. An improved bolt which has a special form of head made and for the
purpose herein before described with reference to Figures 1, 2, 3 & 6.
2nd. An improved stud or bolt which has a special form of head with boss or
projection on same, made and for the purpose herein before described with reference
to Figures 4, 5 & 7.
