PROVISIONAL SPECIFICATION.
An Improved Rolling or Pressing Machine for Casting or Moulding
Plastic and other Materials or Substances.
.
I, JAMES ROBERT SLADE HAYES of 125 Cloudesley Road, Barnsbury, London, N.,
Engineer, do hereby declare the nature of this invention to be as follows:-
:-
My invention relates to the production of a simple, yet withal, efficient machine or
apparatus for rolling or pressing and at the same time casting or moulding into any
particular shape, ornamental or otherwise; plastic, semi-plastic or moist substances or
materials of any kind capable of being moulded into form.
The improved machine according to my invention comprises a preferably rectangular
framework carrying a number of rollers which are mounted loosely in suitable bearings.
These rollers support a horizontal travelling table which is formed into one, two or
more trays or like receptacles having their upper surfaces so arranged to produce the
required ornamental or other shape of the material under treatment contained in said
tray or trays. A toothed rack is formed upon this travelling table which is engaged
by the teeth of a wheel mounted on a shaft arranged transversely above the table
aforesaid.
One or more cylindrical drums or pressing rollers are arranged on this shaft, said
drum or drums which correspond in position and width to the trays or moulds, serving
to press the material contained in the latter into the required shape when the table is
caused to travel by the toothed wheel ongaging with the rack aforesaid.
Slots or openings are cut or otherwise formed in the periphery of the drum or
drams aforesaid within which slots the knife like edges of the raised surface of the
mould tray or trays would enter so as to cut or divide up the material into sections
and thus produce the necessary impression required.
In order that these projecting sharp edges shall coincide with the slots or the like
in the drum or drums I provide a pin or stop or pins or stops at the front end of
the table which enters or enter an opening or openings corresponding thereto in the
drum or drums aforesaid.
When the table has travelled from end to end of the frame and the required
impression imparted to the material contained in the trays formed thereon, fresh
tables are inserted, one after the other, under the pressing rollers or drums and the
operation of moulding the material into form continued as desired.
The shaft on which the toothed wheel and pressing roller or rollers is, or are
mounted, may be driven through suitable intermediate gearing by hand or by motive
power.
The toothed rack before mentioned may be formed on the under side of the
travelling table aforesaid, in which case a second shaft, which might be driven from
the one first referred to, would be arranged under the frame and provided with a
pinion or wheel the teeth of which would engage with and work the rack. I might
also provide the travelling table with shallow, plain trays or the like for the
reception of the material to be pressed, in which case to produce the required shape
of the material to be formed I would cast or otherwise provide the periphery of the
drum or peripheries of the drums with a surface or with surfaces of such configuration
as will impart the required ornamental impression. Further, the teeth of the rack
aforesaid might assume the form of a number of projecting pins, these pins engaging
with a series of links constituting an endless chain which is mounted in any con-
venient manner and driven so as to cause the table to travel by any suitable means.
Dated this 8th day of March 1890.

COMPLETE SPECIFICATION.
An Improved Rolling or Pressing Machine for Casting or Moulding
Plastic and other Materials or Substances.
I, JAMES ROBERT SLADE HAYES, of 125 Cloudesley Road, Barnsbury, London, N.
Engineer, 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 the production of a simple, yet withal, efficient machine or
apparatus for rolling or pressing and at the same time casting or moulding into any
particular shape, ornamental or otherwise, plastic, semi-plastic or moist substances or
materials of any kind capable of being moulded into form.
In the annexed drawing
Figure 1 represents a side elevation and Figure 2 a plan of my improved machine.
Figures 3 and 4 represent respectively by a side elevation and vertical transverse
section the pressing roller or drum, and means for actuating same, all as hereunder
described.
Like letters of reference denote corresponding parts in each of the views.
The improved machine according to my invention comprises a preferably rectangular
framework or bed A supported in any convenient manner and carrying a number of
rollers a which are mounted loosely in suitable bearings. These rollers a support a
horizontal travelling table B which is formed into any number of trays or like
receptacles having their upper surfaces so arranged as to produce the required
ornamental or other shape of the material under treatment contained in said tray 'or
trays. A toothed rack 6 is formed upon this travelling table B which is engaged by
the teeth of a wheel c mounted on a shaft d arranged transversely above the table B
aforesaid. The required motion is transmitted to this shaft from the driving pulleys
through suitable intermediate gearing; if found desirable the machine may be driven
by manual power. One or more cylindrical drums or pressing rollers D are arranged
on the shaft d said drum or drums which correspond in position and width to the
trays or moulds, serving to press the material contained in the latter into the required
shape when the table is caused to travel by the toothed wheel e engaging with the
rack baforesaid.
The pressing drums or cylinders D are preferably built up as shown in Figures 3 and 4
by means of a series of rings or flanges, corresponding in number to the size of the mould
required, which are secured by bolts e to a plate or disc g keyed to the driving shaft
or spindle d and are preferably built up in sections in order to be rendered inter-
changeable to suit the various forms of moulds employed. The edges of the rings are
slightly bevelled so that when bolted together a circumferential recess or groove is
formed between them within which the longitudinal projecting edges formed on the
tray may enter and so divide up the material. If each drum or cylinder D is cast in
one piece I may form in the periphery slots or openings within which slots the knife
like edges of the raised surface of the mould tray or trays would enter so as to cut or
divide up the material into sections and thus produce the necessary impression. In
order that these projecting sharp edges shall coincide with the slots or the like in the
drum or drums B I provido a pin or stop or pins or stops i at the front end of the
table B Figure 3 which enter or enters an opening or openings corresponding thereto
in the drum or drums aforesaid the table being set in motion when the pins or stops i
come in register.
When the table has travelled from end to end of the frame and the required
impression imparted to the material contained in the trays formed thereon, fresh
tables are inserted, one after the other, under the pressing rollers; or, the subsequent
tables may be dovetailed, hinged or otherwise attached to the preceding ones and the
operation of inoulding the material into form continued as desired.
The toothed rack b may be formed on the under side of the travelling table B in
which case a second shaft, which might be driven: from the one first referred to,

page_text: would be arranged under the frame A and provided with a pinion or wheel the teeth
of which would engage with and work the rack b. I might also provide the travelling
table with shallow plain trays or the like for the reception of the material to be
pressed, in which case to produce the required shape of the material to be formed 1
would cast or otherwise provide the periphery of the drum or peripheries of the drums
with a surface or with surfaces of such configuration as will impart the required
ornamental impression. Further, the teeth of the rack aforesaid might assume the
form of a number of projecting pins, these pin's engaging with a series of links
constituting an endless chain which is mounted in any convenient manner and driven
so as to cause the table to travel by any suitable means.
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 :-
First The herein described rolling or pressing machine for casting or moulding
plastic and other materials or substances substantially as specified.
Second-In the machine referred to in the preceding claim the employment of
pressing drums or cylinders D built up in the manner described, toothed wheels c
mounted on the shaft d and engaging the rack b, travelling table B and rollers a
substantially as and for the purposes herein set forth.
