PROVISIONAL SPECIFICATION.
Improvements in the Means of Fastening and Joining Railway
and other Rails and the like.
We, THOMAS COLLIER of 68 Mitchell Street, Radford, Nottingham, Tool-hand,
and HENRY WALKER-HILL of 2 Church Gate, Low Pavement, Nottingham,
Consulting Engineer, do hereby declare the nature of this invention to be as
follows:
The object of our invention is to more effectively secure the bolts used in fastening
and joining railway and other rails, bars and the like from becoming or working
loose in the fish-plates, on other fasteners required for same.
For this purpose we use a pair of 'fish-plates or fasteners of the usual and ordinary
form at each joint of the rails or bars; and have one plate on each side of same, with
the rail ends between them. But, in; place of having the bolt holes in both plates
large enough for the fastening bolts to pass freely through them, we only use one
such plate to each pair having the holes thus formed; and we tap. or form screw
threads in all or some of the holes in the other plate on the opposite side of the rail
joint; in such a manner that the fastening bolts pass freely through the first named
plate and through the rails, but require to be screwed into the holes in the second
named plate, until the bolt heads are screwed firmly up against the first named plate.
We make these bolts of sufficient length, so that a nut of any suitable description
may be screwed on the end of each bolt, until the nut abuts firmly against the
screwed plate.
By this means the Bolts are securely locked or fastened in the the fish-plates. by
simple means.

We, THOMAS COLLIER of 68 Mitchell Street Radford, Nottingham, Tool-hand,
and HENRY WALKER HILL of 2 Church Gate, Low Pavement, Nottingham,
Consulting Engineer, do hereby declare the nature of this invention and in what
manner the saine is to be performed, to be particularly described and ascertained in
and by the following statement :-
The obiect of our invention is to more effectively secure the bolts used in fastening

page_text: and joining railway and other rails, bars, and the like from becoming or working
loose in the fish-plates, or other fasteners required for same.
For this purpose we use a pair of fish-plates or fasteners of the usual and ordinary
form at each joint of the rails or bars; and have one plate on each side of same, with
the rail ends between them. But, in place of having the bolt holes in both plates
large enough for the fastening bolts to pass freely through them both, we only use
one such plate to each pair having the boles thus formed; and we tap er form
screw threads in all or some of the holes in the other plate on the opposite side
of the rail joint; in such a manner that the fastening bolts pass freely through
the first named plate and through the rails, but require to be screwed into the holes
in the second named plate, until the bolt heads are screwed firmly up against the
first named plate.
We make these bolts of sufficient length, so that a nut of any suitable description.
may be screwed on the end of each bolt, until the nut abuts firmly against the
screwed plate. By this means the bolts are securely locked or fastened in the fish-
plates by simple means.
In order that our invention may be fully understood, and more readily carried out
And into effect, we have appended hereunto one sheet of drawings whereon:→→
Figure 1 represents a transverse section through a pair of our improved fish-plates,
as applied to double headed rails.
Figure 2 represents a transverse section through a pair of our improved fish-plates.
of a form as applied to flat bottomed rails.
Figure 3 represents an elevation of the fish-plate shown by Figure 2-on a
reduced scale.
Similar letters of reference refer to similar parts throughout the various figures.
In these figures A is the rail, having a pair of fish-plates B. C, one on each side of
same, of the ordinary and usual form; the bolt holes of plate C are large enough
for the bolt D to pass freely through them, but one or all of the bolt holes in plate. B
are tapped or have screw threads formed therein, -in. such a manner, that after the
bolts have been passed freely through the fish-plate C and rail A, they must be
screwed into one or more holes in plate B until. the bolt head. E is screwed firmly up
ngainst the fish-plate C. The rail A is thus firmly held between the fish-
plates B and C. For further security we prefer to make the bolts D of sufficient
fength that a nut F, either of ordinary or of a self-locking type may be screwed
on the bolt D until it abuts firinly against the screwed plate B, by which means
the bolts D are all securely locked or fastened in the fish-plates B, C.
. We may use bolts with square, hexagon, or other suitable shaped heads and nuts ;
and with or without washers H under the bolt heads or nuts, as may be found most
convenient.
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 :-
1st. In fastenings for joining rails and the like, having one fish-plate C on one side
of the rail or the like with bolt holes K through which the bolts D can pass freely,
in combination with a fish-plate B-on the opposite side of the rail or the like-
having bolt holes I, into which the bolts D must be screwed; for the purposes
herein set forth, and substantially as herein before described, and shown on the
drawings.
2nd. In fish-plates for rails and the like, in which one or more bolt holes in
one plate are tapped or screwed to receive the screwed ends of the fish bolts D,
in combination with the bolts D and nuts F; all for the purposes named, and
substantially as herein set forth and illustrated in the drawings herewith.
3rd. The improved fastening for rails and the like in which are combined an
ordinary fish-plate C, our improved fish-plate B with rcrewed bolt holes L, the
bolts D screwing into fish-plate B, and nuts F; for the purposes set forth herein

page_text: and substantially as hereinbefore described and shown in the accompanying
drawings.
4th. The special arrangement and construction of fastening for rails and the
like for the purposes named above, and all substantially as described and shown on
the drawings herewith.
