COMPLETE SPECIFICATION
An Improved Mould Frame for Producing Plates and Panels of
Gypsum, Cement, and the like
18 to be
I, AUGUST GRIES, of Bielefeld in the Empire of Germany Builder, do hereby
declare the nature of this invention, and in what manner the same
performed to be particularly described and ascertained in and by the following
statement
The object of this frame as represented in the annexed drawings is to cast
plates or panels of cement gypsum or the like such as are used for ceilings of
rooms, and as wainscoting, and it is especially adapted to produce plates or panels
which on account of their peculiar qualities and the manner in which they are
placed, do not show any joints, nor cracks or flaws of any kind
Fig 1 of the drawings represents a plan view of this frame, Fig 2a longi-
tudinal side view, Fig 3 a section on line X X, Fig 4 is a vertical side view
Figs 5 to 9 show various profiles of the plates, thus produced by means of said
frames The frame part A is at each end, by means of the bolts E, pivotally
attached, to the two end parts CC, which latter are provided at then free ends
with slits for receiving the tenons of the fourth part B, the latter being kept in
place by wedges d When the frame is placed on a flat surface and filled with
cement or the like the plate thus obtained after being solidified can by loosening
the wedges d, and turning outward the parts C, be easily separated from said
frame
The interior edges of the frame, are peculiarly shaped as shown in Fig 3, so
that the plates will have edges with corresponding grooves Two of such plates
placed together form as shown in Figs 5 to 9, a joint which is separated towards
the inner end, whereas they meet at the upper end at h for about one third of their
thickness The joint H, the open parts of which lies in the ceiling plane is to be
filled up with cement or the like
The longitudinal interior grooves cause the plates to be firmly united, so that a
loosening or falling out of the cement or other filling is prevented, an occurence
which is so frequent with other systems Each frame may be provided with a
loose sliding cross piece D engaging with the sides of the frame, and shaped with
grooves ribs and the like on one side in conformity with the frame so that smaller
plates or panels may be produced by use of this co-s piece
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, I declare that what I
claim is-
1 Displaceable frame for producing plates and panels of cement or gypsum the
one frame part A of which is pivotally attached to two other opposite frame
parts CC, the latter having at their free ends slots to receive the ends of the
fourth part B which is kept in place by wedges d The inner edges of said frame
being constructed so that the plates are provided with grooves, said grooves
producing for two adjoining plates a joint H enlarged in the interior, and open at
the surface of the plates

page_text: 2 The combination with said displaceable, frames of loose cross pieces D which
render possible the production of shorter plates or panels
