I, JOHN EDWARD BARRACLOUGH ARMYTAGE of Victoria Foundry, Stanningley in
the Township of Pudsey in the West Riding of the County of York Engineer and
Ironfounder do hereby declare the nature of this invention to be as follows:-
In the making of Rail joints hitherto two Fish plates four Bolts with nuts and
washers havebeen used. My improvement consists in additions and alterations to my
invention patented on March 9th 1885 and No. 3068, and supersedes all Fish Plates
Bolts Nuts and Washers.
In the drawings of my Specification No. 3068 it will be seen that the inner Block
marked C. overlaps the base of the Rail but does not touch the head of the Rail in
the underpart. I alter the Block C. making it higher on its whole length-which
is 6 inches long-so that it fits the bevils of the Rail on the under side of the head:
just as it now fits the Bevil over the top of the Base and at present shewn on Fig. 2.
in the drawing of Patent No. 3068.
At each end of Block C. I insert in the mould previous to casting it--two round
wrought Iron pins projecting from face of Block 14 inches and 3" in diameter the
centres of which are 44 inches from each other & correspond in position with the end
holes in each Rail and also with holes one in each end of fixed Jaw into which the
pins penetrate when the inner Block C. is put into position, this gives greater strength
to the pin which prevents any undue opening or closing in each joint through con-
traction or expansion of the Rails.
On referring to Figure 4 of my patent 3068 it will be seen that the round Drift
pin is fixed in a horizontal position. I now fix the pin in a slightly inclined position
the thick end being highest so that it naturally tightens itself by gravitation.
The rectangular Box b. and the outer block d. and the round drift pin e. 1 only
alter in their proportions of size all these being larger for the joint than for the
ordinary chair. This joint is to be relied upon for strength.
My invention has a great superiority over all other joints in use by reason of its
great simplicity its firmness and the despatch and ease with which it can be fixed and
unfixed.
Dated this 29th day of April 1887.

Invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-

DESCRIPTION OF DRAWINGS.
Fig. Tisa front elevation in section of my improved joint with rail.
Fig. 2 is a sectional plan of Fig. 1 on the line A. B.
Fig. 3 is an end elevation of Fig. 1, showing position of pin.
Figs. 4 and 5 aro detached views of block C
Cis the inner loose block, D the rail, and E the fast jaw or block, F is the outer
loose block, G is the rectangular box, H is the drift pin.
The loose block C is made to fit the bevel of the rail D, both on the underside of
the head and on the top side of the base of the rail; also I insert in the mould for
the block C (previous to casting it) two wrought iron or steel pins J, projecting
from the face of the block, these pins pass through corresponding holes in the
rail D, and into recesses in the fast jaw or block of the chair: the outer loose block
is then put into its place, and the drift pin is put in and secures the whole of the parts
together.
The holes in the rails through which the pins J pass, are larger than the pins so
as to allow for a little contraction and expansion of the rails. the drift pin is
slightly inclined, the thick end being highest, so that it naturally tightens itself by
gravitation.
This construction of chair and joint can be relied upon for strength and
durability, and is superior to all other joints now in use by reason of its simplicity,
firmness, and despatch in fixing, removing or adjusting.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :-
1. The use of the moveable block C, binding on the bevels of the rail D, having
binding pins J, J, which pass through the rail, and enter into the fast jaw E,
substantially as and for the purposes shown and described.
2. Placing the drift pin for securing and tightening the blocks at an angle as and
for the purposes shown and described.
3. The general arrangement and construction of chairs and blocks substantially
as shown and described.
Dated this Twenty seventh day of January 1888.
