Gentleman for an Invention of "IMPROVEMENTS IN THE PERMANENT WAY
OF RAILWAYS, TRAMWAYS AND THE LIKE, PARTS OF WHICH ARE APPLICABLE
TO OTHER PURPOSES"
PROVISIONAL SPECIFICATION. left by the said James Kenyon at the Office
of the Commissioners of Patents on the 9th October 1883.
JAMES KENYON of Blackburn in the
"IMPROVEMENTS IN THE PERMANENT WAY
County of Lancaster, Gentleman.
OF RAILWAYS, TRAMWAYS, AND THE
LIKE, PARTS OF WHICH ARE APPLICABLE TO OTHER PURPOSES."
"
My invention relates first, to the nuts bolts and fishplates employed in connecting
and securing the rails of the permanent way of railways, tramways and the like,
and secondly, to an improvement in the rails
In performing the first part of my Invention I make the holes in the fish plates
conical for the special nut hereafter described and I also prefer to make the square
hole for the bolt head taper,
The nut is made preferably in one piece with a taper collar under the head.
This taper collar is either made rough or may be "turned" and is split or divided
by one or more vertical slots: or the taper collar may be used without such slots :
I prefer to taper the square of the bolt or it may be of the ordinary shape
In connecting the rails of permanent way I employ fish plates as usual. I form
conical or taper holes in the fish plates for the nuts and preferably for the bolt
heads: the nuts are put on the bolts with the taper part first; the taper portion
enters the conical hole in the fish plates and when screwed up the conical hole
compresses the taper collar on to the bolt thus giving solidity to the nut, bolt and
fish-plate, also permanently securing the nut. When the bolt head and fish plate
are made to fit by taper surfaces the joint is improved and made stronger
I have described this part of my Invention as being particularly applicable to
the permanent way of railways, tramsways and the like but the taper collared nut
or nut and bolt are applicable also for general purposes.
The second part of my Invention consists in making or punching slots in the
rails through the web at points where the rails rest on the chairs to prevent rigidity
and to give elasticity to the rail at these points and also for the better securing
of the wooden keys.

" IMPROVEMENTS IN THE PERMANENT WAY OF RAILWAYS, TRAMWAYS, AND THE

"
My invention relates first, to the nuts, bolts and fish plates employed in connecting
and securing the rails of the permanent way of railways, tramways and the like
and secondly, to an improvement in the rails.
In performing the first part of my Invention I make the holes in the fish plates
conical for the special nut hereafter described and I also prefer to make the square
hole for the bolt head taper.
The nut is made preferably in one piece with a taper collar under the head.
This taper collar is either made rough or may be "turned" and is split or divided
by one or more vertical slots: I prefer to taper the square of the bolt or it may be
of the ordinary shape.
In connecting the rails of permanent way I employ fish plates as usual. I form
conical or taper holes in the fish plates for the nuts and preferably for the bolt
heads the nuts are put on the bolts with the taper part first; the taper portion
enters the conical hole in the fish plate and when screwed up the conical hole
compresses the taper collar on to the bolt thus giving solidity to the nut, bolt and
fish plate, also permanently securing the nut. When the bolt head and fish plate
are made to fit by taper surfaces the joint is improved and made stronger.
I have described this part of my Invention as being particularly applicable to
the permanent way of railways, tramways and the like but the taper collared nut
or nut and bolt are applicable also for general purposes.
The second part of my Invention consists in making or punching holes or slots
in the rails through the web at points where the rails rest on the chairs to prevent
rigidity and to give elasticity to the rail at these points and also for the better
securing of the wooden keys.
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings, reference
being had to the figures and letters marked thereon.
Fig. 1 is a sectional elevation of a rail, fish plates and bolt to which my Invention
is applied. Fig. 2 shows the nut with the bolt in section and Fig. 3 shows a
longitudinal elevation of my improved rail.
a is the rail: b 61 are the fish plates in which are taper holes: but the fish
plate b may have a square hole that is not tapered, if desired: c is the nut having
a conical projecting end or collar o¹ that fits the conical hole in the fish plate bl:
in this collar c¹ are two slots: d is the bolt with a tapered head to fit a taper hole
in the fish plate b. When the nut has been tightened it compresses the taper
collar c¹ which grips the screw on the bolt d: the fish plates and rails are held very
securely and the nut will not become loose by jarring.
This improved nut may be used for various purposes where locknuts are
required.
My improved rail has holes or a slot a¹ (see Fig. 3) at each point where it is
held by a chair and in addition to the slot, or in lieu thereof, I place a packing of
lead or other material between the rail and the chair to deaden the jar.

page_text: Having stated the nature of my Invention and described the manner of performing
the same
I declare that I claim
1. The improved device for securing rails, substantially as herein described and
as shown on Figs. 1 and 2.
2. A taper slotted nut, substantially as and for the purposes herein described and
as shown
3. The improvement in rails herein described and illustrated by Fig. 3.
In witness whereof I the said James Kenyon have hereunto set my hand
and seal this eighth day of April, One thousand eight hundred and eighty four.
JAMES KENYON (L.S.)
