I FRED CRAVEN, of Phoenix Works, Brighouse, in the County of York, Machine
Maker, do hereby declare the nature of my said invention for "IMPROVEMENTS IN
DRAW BAR CONNECTIONS APPLICABLE TO RAILWAY CARRIAGES AND RAILWAY WAGGONS
AND OTHER LIKE VEHICLES "
to be as follows:-
According to this my invention I employ for each carriage or waggon connection
two lengths of tubing of such relative diameters as that one will enter and slide
within the other, and to the end of each tube is affixed a concave disc or hollow
mushroom shaped head-The sides of the longer and outer tube are cut away for a
distance leaving two concave strips so that when the tubes are placed end to end
and the hollows or concave parts of the heads are opposite each other, the tubes
will slide one upon the other, the two strips of the outer tube passing through two
holes in the coucave head of the inner tube thus allowing the concave heads to
approach each other and to nip between them a disc of india rubber or other like
elastic packing-The tubes are to be attached to the draw bars so that on tension
being applied, the concave heads nip the india rubber or other packing between
them and ease the strain after the manner of spring draw bars.

Carriages and Railway Waggons and other like Vehicles.
I, FRED CRAVEN of Phoenix Works Brighouse, in the County of York Machine
Maker, do hereby declare the nature of my invention for "IMPROVEMENTS IN DRAW
BAR CONNECTIONS APPLICABLE TO RAILWAY CARRIAGES AND RAILWAY WAGGONS, AND
OTHER LIKE VEHICLES " and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
According to this my invention I employ for each carriage or waggon connection
two lengths of tubing of such relative diameters as that one will enter and slide
within the other, and to the end of each tube is affixed a concave disc or hollow
mushroom shaped head.
The sides of the longer and outer tube are cut away for a distance leaving two
concave strips, so that when the tubes are placed end to end and the hollow or
concave parts of the heads are opposite each other, the tubes will slide one upon the
other, the two strips of the outer tube passing through two holes in the concave
head of the inner tube, thus allowing the concave heads to approach each other and
to nip between them a disc of india rubber, or other like elastic packing.
The tubes are to be attached to the draw bars so that on tension being applied,
the concave heads nip the india rubber, or other packing between them and ease
the strain after the manner of spring draw bars.
Such being the nature and object of my said Invention, the following is a
complete description of same, reference being had to the accompanying drawings
forming a part of this Specification in which
Fig. 1 is a side elevation of the apparatus complete.
Figs. 2, 3, and 4 shew the parts detached in order to better illustrate the
construction thereby.
Fig. 5 is end view of bars herein referred to as 1, 1, 1ª, 1º.
Fig. 6 is a plan of the framing of a carriage having my improved apparatus
applied therein.
At 1, 1, 1, 1 are halves or parts of a tube or sectional V bars of such diameter
as when placed end to end, and slided one within the other and through the
discs 4, 5, the parts 1, 1, 1º, 1º form in the space between the said discs a complete
tube or a complete bar, and to the ends of which is cast or coupled the bosses 2, 3,
the hollow or concave discs 4, 5, are placed upon the tubes or bars 1, 1, 1 1 and
between the discs is the ring of india rubber or spiral spring 6-the bosses 7, 8, are
secured on the ends of the V bars by means of the cutters 9, 10, and at 11 is a
cotter for securing the boss to the ordinary draw bar of the waggon. On tension
being applied to the draw bars, the action is to draw the concave discs towards
each other, and thus nip the india rubber ring between them, and that as such
contrivance is to be applied to the several carriages or waggons composing a train,
the whole in practice constitute one long and elastic bar, and it will be seen that
there is no strain or drag whatever upon the cross beams or framing 12 of the
carriage.

page_text: I am aware that hollow discs and india rubber rings have been applied to the
framing of a carriage in combination with a draw bar, and to such I lay no claim,
what I do claim is;
The hollow discs and india rubber ring (or spiral spring) 6 in combination with
the bars or parts 1, 1, 1 1, slided one within the other and constituting between
the said discs a solid or complete bar together with the connecting bosses and
couplings herein fully illustrated by drawings and as set forth.
