PROVISIONAL SPECIFICATION.
Improvements in Machines for Moulding Plastic and Powdered
Substances.
I, HEZEKIAH TEMPEST of Thwaites Brow, Keighley in the County of York,
Manager, do hereby declare the nature of this invention to be as follows, that is
to say:
It relates more especially to machines or mechanism for moulding and com-
pressing artificial fuel into suitable rectangular or spherical forms or shapes
although same may be employed with equal advantages for operating upon other
plastic or powdered substances and consists of arranging and constructing these
machines or mechanisms in such a manner that the motions of the several parts
shall be continuous and not intermittent.
In accordance with my said invention the substance to be moulded or operated
upon is made to pass down a shoot or hopper, which guides it into suitably formed
moulds, that is to say, moulds to form same into rectangular or spherical or other
shapes. These moulds are mounted upon or made to form part of an endless chain
which passes over appropriately formed sprocket wheels or rollers mounted in
framework to hold said moulds in proximity with the shoot or hopper.
The endless chain with its moulds is preferably made to pass over supporting
framework arranged between the sprocket wheels, and above these moulds are
made to operate plungers or compressing pistons that are mounted upon rotary
discs, drums or carriers.
These plungers are caused by suitable guide pieces, as cranks and rods or
stationary guides mounted on discs arranged to be in proximity with same, to
descend and ascend vertically into and out of the moulds although said moulds are
continuously moving beneath same.
To effect the discharge of the moulded substances from the moulds, as these
latter are carried by the chain, their openings which extend upwards, are brought
in a certain part of their path of motion, to extend downwards so that their contents
may be thus discharged and provided such contents will not by gravity descend or
fall out of said moulds then I mount plungers on a supplementary wheel or disc to
forcibly eject or dislodge same, which may then fall into a hopper or shoot or on
to a travelling belt so as to be thence carried to any place desired.

Improvements in Machines for Moulding Plastic and Powdered
Substances.
I, HEZEKIAH TEMPEST of Thwaites Brow, Keighley in the County of York,
Manager, 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, that is to say :-
It relates more especially to machines or mechanism for moulding and com-
pressing artificial fuel into suitable rectangular, cylindrical or spherical forms or
shapes although same may be employed with equal advantages for operating upon
other plastic or powdered substances and consists of arranging and constructing the

page_text: parts or mechanisms forming these machines in such a manner that the motions of
the several motor parts shall be continuous and not intermittent.
In order that my said invention may be more readily understood I have hereunto
appended sheets of drawings, to which, by figures and letters reference is made in
the following description.
Fig. 1 is sectional side elevation of a machine inade in accordance with this
invention, all the framework is omitted and most of the toothed gearing wheels
are shown by chain or broken lines for the sake of clearness.
Fig. 2 shows certain of the gearing wheels in position as seen from above.
Fig. 3 is end elevation of the machine as seen in the direction of the arrow A,
Fig 1.
Fig. 4 is sectional side elevation of a portion of the machine showing the
arrangement of certain parts of the framework.
Fig. 5 is a view of parts shown by Fig. 4 as seen from above.
Fig. 6 is sectional side elevation illustrative of the filling apparatus.
Fig. 7 is sectional end elevation of said filling apparatus.
Figs. 8 and 9 are illustrative of the two opposite sides of the rotary mechanism
mounted in the hopper or shoot through which the material is supplied to the
machine.
Similar letters and figures of reference indicate similar parts in all the several
views.
In accordance with my invention the substance to be moulded or operated upon
is made to pass down a shoot or hopper a in which are mounted the rotary discs bb¹
the space between these being divided into compartments c by means of the radial
partitions & and concentric partition e. In the compartments c are made to operate
the compressing plates f which are mounted upon the levers and pivoted on
the discs at 3, and which are made to assume, when free, a normal position by
means of the retracting springs f so that as the discs b.b' rotate (their rotary
motion being derived from the shaft 2 by means of gearing wheels the pitch lines
of which are shown in broken lines Fig. 1) each of these plates f is against its
partition d when passing over the top of or above the shaft 3 (see Fig. 6), but by
their bowls coming in contact with the cam plate g as their said discs b b¹
continue their motion, said springs f* are overcome and the plates f are made to
approach the partition d at the other side of the space c by which means any or all
of the substance contained within each of these respective spaces c is compressed
into form ready for being forced by the pistons into the receptacles or chain
moulds as they (these spaces c) are successively brought to be vertically over or
above said moulds k.
The downward. motion of the pistons is effected by the rotary cam m, their
return motion being secured by the resilience of their springs m'.
The moulds are preferably of the cylindrical form as shown, although they
may be of other shapes, and these moulds & are formed or constructed so that they
may be linked together, as by the coupling pins n, to form an endless chain.
This endless chain of moulds k is made to pass over supporting framework p
and p' (see Fig. 4) in its passage between the sprocket wheels q and q' by which
it is operated, and above these moulds are made to operate plungers that are
mounted upon the shafts carried loosely by the discs sands, the discs forming
a spur wheel through which its rotary motion is derived from the wheel t on the
prime motor shaft 5 while the disc s' is formed for merely carrying the other ends
of the shafts and is, together with the disc s, keyed upon the shaft 6 so that the
whole may revolve together.
These plungers r are caused to descend vertically into and ascend vertically out
of the moulds k, (preferably by means of the toothed wheels fixed upon the
shaft, gearing with the wheel w mounted loosely upon the shaft 6, this wheel w
being rotated by suitable intermediate wheels and gearing and in the proper
direction to effect this object, or instead of this arrangement of means being
employed cams, cranks or other well known guiding means might be used) although,

page_text: as said plungers rare thus descending and ascending, the moulds & are continuously
passing beneath them.
To effect the discharge of the compressed substance from the moulds k, as these
are carried by the wheels g q', when in the position for their open ends to be down-
wards, a vibrating plate, pivoted at ¹ and operated by any suitable cam, crank
or other mechanism, is made to press upon the extending ends of the discharging
pistons y forcing same downwards by overcoming their springs y' thus their other
ends press the contents of the moulds k entirely clear of same, while when they
have moved beyond the reach of this plate x, said springs y¹ retract them into their
normal positions.
Provided any substance of a harder nature than the one of which the artificial
fuel is compounded, is by accident fed to the mould k, the plungers r are allowed
to yield in order to pass over same after exercising a certain pressure thereon, by
means of their shaft 6 raising the levers z z¹, these levers z¹ being coupled by
rods 7 and 8 to the cross bar 9 which operates the toggle levers 10 and 11 (the
lever 11 having its upper end retained in position by the fixed rail 12 while its
arm 13 has the retracting weight 14 mounted upon it) so as to move same against
the weight 14) into the position shown in broken lines Fig. 1.
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
claim is :-
1. The combination of an endless chain of moulds with one or a series of rotary
plungers substantially as herein set forth and for the purpose specified.
2. The combination with an endless chain of moulds, of a series of rotary
plungers together with means for causing same to descend and ascend vertically
into and out of said moulds substantially as specified.
3. The combination with an endless chain of moulds and a series of rotary
plungers, of a shoot or hopper having rotary filling mechanism mounted therein
substantially as and for the purposes specified.
4. The combination of an endless chain of moulds and a series of rotary
plungers, with means for discharging the contents of said moulds substantially as
herein set forth.
5. The combination of the rotary plungers and an endless chain of moulds with
means for weighting said plungers and allowing them to yield when the upward
force is greater than said weight substantially as specified.
6. The general arrangement, construction and formation of the several parts
forming the mechanism herein described substantially as specified.
