COMPLETE SPECIFICATION.
Improvements in and relating to the Casting of Shelf and other
Brackets.
FRED. RYLAND of West Bromwich Staffordshire Ironfounder 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 my invention relates to improvements in and relating to the casting of shelf
and other brackets and the object of my said invention is to effect certain new and
useful improvements in the method which is at present employed and which
improvements will be hereinafter fully described and set forth. In order that my
invention may be more readily understood reference should be made to the
accompanying drawings in which like letters indicate corresponding parts through-
out the figures and in which
Fig. 1 shews the method usually employed in casting brackets.
Fig. 2 shews a plan view of my improved system and
Fig. 3 is a cross section of the same.
Fig. 4 is a section through the line B. C in Fig. 1 and
Fig. 5 is a section through the line D, E in Fig. 3.
Hitherto shelf brackets have been cast in the manner illustrated in Fig. 1 on
which A represents the pattern which is laid in the sand sideways, there being usually
2 patterns in one mould arranged as illustrated. With the old method very few
patterns can be used in one mould.
A further disadvantage in the old method of casting brackets is that the
flange G G shewn on Fig. 4 is necessarily made with a strip to leave the sand and
thereby prevents the flange of the bracket bedding square against the wall and shelf
which they are intended to support.
My improved method is illustrated in Figs. 2 & 3 consists in casting the brackets
edgeways by which means I am enabled to insert a greater number of patterns A
in the sand without increasing the size of the mould in which the brackets are cast,
thereby economizing time and space.
My improvements will be readily understood and appreciated by those skilled in
the art to which it appertains and the advantages obtained by the employment
thereof. It also enables me to cast the brackets with a bridge section thereby
giving greater solidity and strength to the bracket as shewn on Fig. 5.
In my improved method the upper edges of the flange marked Fmust necessarily
be always perfectly square with the centre of the bracket thus making it bed
perfectly true on to the wall or shelf to which it is intended the bracket should
support.
By my invention also the hole for the insertion of the screws by which the
bracket is screwed to the shelf may be cast therein instead of being afterwards
drilled and countersunk as is usual in the ordinary method and a more substantial
looking bracket may be cast in this manner without increasing the weight of metal.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is,
1. The improvements in and relating to the casting of brackets substantially as
described and illustrated.
