I WALTER AYRES of the firm of Ayres and Co of 305 Kingsland Road in the
county of Middlesex Ironfounder do hereby declare the nature of my said
invention for IMPROVEMENTS IN THE MANUFACTURE OF WEIGHTS TO BE SUSPENDED
BY CORDS FOR SASHES AND OTHER PURPOSES to be as follows:-
This invention relates to certain improvements in the manufacture of weights to
be suspended by cords for sashes and other purposes.
1 cast these weights in a chill said chill being made with the requisite cavity or
cavities in two parts and within the chill at the point where the cord holes in the
weights have to be provided I make a projection or projections which stand up in
the cavity or cavities.
For instance in the cavity of a chill made in two halves I provide two projections
one in each half of the chill; these projections will be conical or tapered and abut
against each other end to end when the two halves of the chill are laid together, or
a single projection may be made in one half. In either of these cases and in'
combination therewith, I employ an end plug of conical form which will be made
to abut upon the inner end of the aforesaid projections or projection.
"
When the molten metal is poured in (whether a single chill or a chill box con-
taining a number of moulds) the metal runs into the cavities around the projections
and end plug so that when the chills are to be opened the end plug will be.
withdrawn aud on lifting the top half or halves of the chill the projections will
draw away leaving the piercing or hole in the weight for reception of the
suspending cord.

I WALTER AYRES of the firm of Ayres & Co 305 Kingsland Road in the County
of Middlesex Ironfounders, do hereby declare the nature of my invention for
"IMPROVEMENTS IN THE MANUFACTURE OF WEIGHTS, TO BE SUSPENDED BY CORDS
-FOR-SASHES-AND_OTHER_PURPOSES 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 certain improvements in means for the manufacture of
weights to be suspended by cords for sashes and other purposes.
I cast these weights in a chill said chill being made with the requisite cavity or
cavities in two parts and within the chill, at the point where the cord-holes-in-the-
weights have to be provided; I-make-a-projection or projections which stand up in
the cavity or cavities. For instance, in the cavity of a chill made in two halves
I provide two projections-one-in-each-half-of-the-chill, these projections will be
conical or tapered and abut against each other, end to end, when the two halves of
the chill are laid together, or a single projection may be made in one half of 1
the chill.
In either of these cases and in combination therewith I employ an end plug of
conical form which will be made to abut upon the inner end or ends of the afore-
said projection or projections.
In order that my invention may be more clearly understood I have hereunto
annexed a sheet of drawings wherein Fig 1 is a longitudinal section of a chill
constructed according to this invention. Fig 2 an end view of part of a series of
such moulds. Fig shows, in section, modification wherein but one projection
is used.
a, a¹ is the chill box with the cavity b. in which the cast weight is to be formed
o clare the conical or tapered projections, abutting when the chill box is closed;
and d, is the conical plug abuting on the inner ends of the projections c, c¹ ; e, is
the pouring hole through which the molten metal is poured into the mould, and
this said pouring hole at its lower end e¹, that is at the point where it meets the
cavity in which the cast weight will be formed, is of less area than is the metal on
each side of the projecting pieces c, c' forming the eye or cross hole and this less
area at e¹ is necessary so as to ensure the metal breaking off at that point instead
of at the eye or cross hole.
When the molten metal is poured in at e, (whether a single chill or a chill box
containing a number of moulds) it runs into the cavities around the projections c, c¹,
and end plug d, so that when the chills are to be opened the end plug d, will be
withdrawn and on lifting the top half or halves of the chill the projection or
projections will draw away leaving the piercings or hole in the weight for
reception of the suspending cord.

Invention, and in what manner the same is to be performed, I declare that what
I claim is
In a chill-box for the manufacture of weights the projection or projections c, o¹
and the plug d, as herein described and shown by the drawings.
