PROVISIONAL SPECIFICATION.
Improved Spring Stops for Railway Waggon Doors.
FRANK FERRIS, Siddington, Cirencester, Glouster, Carpenter and Waggon
Builder, do hereby declare the nature of this invention to be as follows:-
:-
The invention is four spring stops, fixed on the under frame of the waggon,
and so arranged, that when the flaps or doors are opened, the door hinges fall on
the stops instead of the sole bar. The stops can be fixed to either wood or steel
framed waggons.
Improved Spring Stops for Railway Waggon Doors.
FRANK FERRIS, 15, St. Margaret's Road, Old Swindon, Wilts, late of Siddington,
Cirencester, Gloucester, Carpenter & Waggon Builder, 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:-
This invention relates to the improvements in stops for railway waggon doors,
the object being to provide springs for taking the blow and weight of the said
doors when falling, in order to save the same from damage through violent
contact with the sole bars or other part or parts of the railway waggon.
Such being the nature and object of my said invention, the following is a com-
plete description of the same, references being had to the accompanying drawings,
in which :-

Figures 1, 2 and 3 represent the elevation, cross section, and plan respectively
of a railway waggon, the nature of the invention being shown in each figure,
the stops
a" having taken the weight and blow of the waggon door "e" act
on, and deflect the spiral springs "c." The said spiral springs c" are of such
strength that they are only deflected sufficiently to form a safe cushion for the waggon
door, and to prevent the said door from striking heavily on any other part or parts
of the railway waggon, except on the said stops "a." The said spiral springs are
fixed between the iron or steel plates "d" which are bolted to the under frame
of the railway waggon, and are deflected by the collars "b" which are forged on
"
"
the stops a. The said stops are enlarged at their outer ends by a round nut
screwed and pinned on the said outer end, and having a rounded contact surface.
