COMPLETE SPECIFICATION.
Improvements in Moulding Machines.
I, EMIL UBRIG, of the Firm of E. Ubrig and Co. of Charlottenburg, near Berlin,
Germany, Engineer, do hereby declare the nature of my said 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 a moulding machine which with only one up and down
stroke prismatic or cylindrical parts of a pattern can be withdrawn from the moulding
box, whi
is rammed full of sand, and the said box or frame lifted perfectly uniform
and in v ical direction from the conical or tapered patterns fixed to the upper plate
of the mulding machine.
In the accompanying drawings, Figures 1, 2 and 3 are vertical sections through the
machine representing the parts in different positions,
Figure 4 is a part section of the machine rectangular to the foregoing figures,
Figure 5 is a top view of the machine,
Figure 6 is a top view of details of the same.
In Figures 1, 2 and 3 the moulding box is rammed full, in Figure 5, however,
empty.
A vertical sliding carrier or rest d, which can be readily moved up and down by
the lever e, is arranged in the guides c of the frame b provided with top plate a. The
moulding box f, which is guided by pins g or in other suitable manner, is placed on
the top plate a and is filled with sand for surrounding the pattern i, k.
The cylindrical parts of the pattern is attached to the plate of the carrier d, and
the upwards tapered part k to the plate a. The plate a fits exactly over those parts of
the pattern which are fixed on the plate 1. On the cross head m, n, forming the
connection between the carrier spindles d, a similar head, the arms p of which are of
equal length with the arms n of the head m, n, is arranged.
Besides this, four vertical spindles are arranged in the sides of the frame b, run in
appropriate guides and are provided with horizontal pins or pegs s, so that the said
spindles in certain positions of the parts of the machine cannot fall out of the same.
Before the moulding box or frame fis rammed full of sand, the carrier d is brought
to its highest position, Figures 1 and 3, and secured against automatically sinking by
means of a stop lever t, u, the longer arm u and short arm or tappet t of which lay on
the surface w of the frame of the machine and are connected by the link or arm v to the
lever e.
If the filled and rammed moulding box or frame is to be removed from the
machine the lever t, u, is brought into line with the link or member and the carrier d
lowered to its lowest position, Fig. 2, by means of the lever e.
The cross head p, q, is now brought into such position to the cross head m, n, that
the ends of the arms p will cover the borings in the arms n for the passage of the
spindles. When the carrier d is now moved upwards the spindles rrest on the ends p
of the cross head p, q, and press against four legs or pins on the moulding frame f
so that the latter is lifted gently and uniformly from the plate a and pins 9 without
any injury to the moulds, (Figure 3).
"
By turning the lever t, n, into the position represented in Figure 4, the carrier d
will be retained in its highest position, and when the mould has been removed from
the machine, and the spindle released from pressure, the cross head p, q, can be
turned back into the position as shown in Figure 6, so that the spindles r sink into
their former position, as represented in Figures 1 and 2. If a fresh box f is now
placed in the machine a new mould can be made.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1-A moulding machine in which, by means of an un and down movement

page_text: the cylindrical parts of the pattern fixed to a vertically moving carrier operated
by hand are drawn downwards out of the "mould, whilst the conical or tapered
parts of the pattern attached to the moulding plate a are removed from the mould by
raising the moulding box or frame by means of a device operated by hand and con-
sisting of a rotary cross head p, q, arranged above a vertically reciprocating cross
head m, n, connected to the carrier d, the head p, q, being so arranged that in one
position the spindles for lifting the moulding box or frame will not be operated
when the carrier is raised or lowered, whilst in the other position will lift the
moulding box or frame by means of the spindles r perfectly level and uniformly
when the carrier d makes its upward movement, substantially as specified, and
shown.
2: My improved moulding machine, substantially as specified in the foregoing
specification, and illustrated by the accompanying drawings.
