Complete Specification Left, 5th Apr., 1890-Accepted, 10th May, 1890
PROVISIONAL SPECIFICATION.
An Improved Double Buckle or Cradle for Springs used in Railway
Waggons and other Rolling Stock.
I JAMES MITCHELL, of the Bute Spring Manufacturing Works, Cardiff, in the
County of Glamorgan, Railway Spring Manufacturer, do hereby declare the nature of
this invention to be as follows:-
My invention relates to improvements in the manufacture of buckles for holding
the plates of draw-bar springs together.
It has hitherto been the practice to make buckles by forging them, and welding
lugs to each corner, to which lugs the draw-bar is attached. But the difficulty of
making absolutely perfect welds, and the risk of not getting the grain of the metal in
the right direction, have proved to be fruitful sources of accident.
According to my invention, we prepare two channel or U-shaped pieces, and these
are placed one on each side of the spring with their backs against the spring. I
further provide a confining plate for each side of the said two U-shaped pieces, and
suitable bolt-and-nut connections for holding the pieces and plates to the spring, and
providing for the attachment of the draw-bar thereto.
I may make the U-shaped pieces above mentioned by cutting up a bar of the
proper cross section.

COMPLETE SPECIFICATION.
An Improved Double Buckle or Cradle for Springs used in Railway
Waggons and other Rolling Stock.
I, JAMES MITCHELL, of The Bute Spring Manufacturing Works, Cardiff, in the
County of Glamorgan, Railway Spring Manufacturer 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:-
My invention relates to improvements in the manufacture of buckles for holding
the plates of draw-bar springs together.
It has hitherto been the practice to make buckles by forging them, and welding
lugs to each corner, to which lugs the draw-bar is attached. But the difficulty of
making absolutely perfect welds, and the risk of not getting the grain of the metal
in the right direction, have proved to be fruitful sources of accident.
In order that my invention, and the means by which the same is to be carried into
practical effect may be thoroughly understood, I will now describe them in detail,
referring in so doing to the accompanying drawings, which are to be taken as part of
the specification.
Figs. 1 and 2 are respectively sectional elevations of the plan of the buckle made
according to the usual method, that is by welding lugs a. to each corner of the buckle
proper b.
Fig. 3 is a side elevation of a truck, to which my invention has been applied,
showing the improved buckle in section at c. and the sectional elevation by dotted
lines at d.
Fig. 4 is a plan of a truck with half the body removed so as to show my improved
buckle.
Figs. 5 and 6 are respectively plan and side elevation the latter partly in section.

page_text: Referring to the two latter Figs. e. e. are a pair of side cheeks having shaped
ends ff. These may be produced by any convenient method. 9. g. are a pair of
U-shaped shoes of a proper size to embrace the ends of the draw bar attachments h. h.
and bed close up against the inner faces of the cheeks e. e. when the ends f. f. bed
against the said attachments. i. i. are rivits, and j. j. draw-bar pins.
Having now particularly described and ascertained the nature of my said inven-
tion, and the mauner in which the same is to be performed, I declare that what I
claim is
The combination of cheeks having | shaped ends and U-shaped shoes adapted to
embrace, and to connect a pair of draw bar attachments substantially as and for the
purpose set forth.
