JOHN PEARSON Clerk of Works No. 1 Levenshulme Street Gorton near Manchester
do hereby declare the nature of this invention to be as follows:-
Improved slopstone, say take size to be 2′ 6″ long x 1' 6" wide x 5" in thickness.
I make a mould of timber as per sketch plan No. 1 and sections marked 2 & 3. The
four straight pieces are each 5" deep and 1" thick and corner piece marked A is cut
to required pattern say radius 4" diameter with rebate cut out at back of each end,
balf the thickness of timber, the two straight pieces that join A are cut to fit and
screwed together. the other two pieces are then joined making the inside measure-
ment 2' 6" x 1' 6". Close jointed 1" boards are then screwed on to form bottom.
This mould must be made larger at top edge to allow of easy removal of slopstone
when moulded. Then bore 8 holes through bottom for dowels as marked on
plan No. 1.
The mould to form inside portion of slopstone must be made 2' 33" x 18" x 33"
deep-this will allow for sides, ends, and bottom of slopstone to be 14" thick, but
this can be varied as required. The two side pieces A and B see plan (No. 2) are
made 2' 0" x 14" x 33". The end piece marked C is made of two pieces of equal
length joined together in centre by binge fixed with knuckle flush with outside face.
C measuring 134″ × 1″ × 37° deep, one end each of A and B and both ends
of Care then cut at an angle of 45° or mitred together at right angles when standing
on edge, these pieces are then fixed together with hinges (see plan No. 4) fixed flush
inside corners marked and y. on plan No. 2) the hinges must not exceed 3" in
length and be fixed without shewing on either edge. The end piece D is made
13" x 3" x 33" deep with one end cut circular radius 34" (see plan No. 2).
When these pieces A B C and D are placed in position, the centre space is fitted
with board 1' 11" x.1' 0" x 1" thick (marked E on plan No. 2). This board
requires fourteen strips of wood 8" x 1" x 8" fixed four on each side and three on
each end, these pieces when placed on board E at right angles to edges must. project. "
and each fixed by screw 1" from edges of board E. Now make a groove in
pieces (A B C and D) on the inside, exactly the thickness of board E from lower
edge of each. The groove in piece D must stop short of each end. Next lay
pieces A B C and D on flat surface with grooves on lower side. Take board E and
turn the strips or buttons until paralell with the edges, next insert E (with buttons
upwards) between pieces A B C and D, the buttons must now be turned until they
are at right angles with edges of E, when one end of each will enter grooves and if
all are nicely fitted. A B CD and E will all be now held firmly together. E being
a level surface with edges of A B C and D. The corners must now be rounded off,
as shown in plan No. 2 and in sections 3 and 4.
A groove or mould must now be made on the top and outside edges of A B C
and D, to form projection on slopstone as seen at full size section marked F.
Then place this mould inside large one with board E upwards and when equal
distance from each side and ends, marked through holes for dowels. Fixing two each
in A B C and D, these iron dowels to project out say 3 and should taper smaller to
top to allow of easy slipping off. Then fix a turned pillar on board E see plan No. 3
to form hole for waste pipe, this can be fixed in any position the pipe may be required.
The mould is now ready for work but care must be taken to see that the inner mould
(No. 2) is pressed closely down.

page_text: Then fill in material level with edges of mould (No. 1) and as soon as the
material is sufficiently set, the mould must be turned bodily over, when mould
No. 1 will slip off, leaving exposed the buttons on board E as seen in plan No. 2
now turn all buttons until paralell with edges, and board E can be lifted out by
handle. A B and C can then be moved forward as shown on plan No. 4 and taken
out without injury to rim or slopstone, next remove D and moulding is complete.

Apparatus for Moulding the same.
JOHN PEARSON Clerk of Works 1 Levenshulme Street Gorton Manchester, 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:-
Improved slopstone say take size to be 2' 6" long x 1' 6" wide x 5" in depth. I
make a mould of timber for outside of slopstone, as per sketch plan No. 1 and
sections marked 2 and 3. The four straight pieces are each 5" deep and say 1" thick,
the corner piece A is cut to required pattern say radius 44" diameter with rebate cut
out at each end half the thickness of timber, the two straight pieces that join A are
rebated at end to fit and screwed together, the other two pieces are then fixed making
the inside measurement 2' 6" x 1' 6", close jointed I" boards are then screwed on to
form bottom. This mould is made larger at top to allow of easy removal of slopstone
when moulded.
The mould to form inside of slopstone, must be made 2' 34" x 1'3" x 3" deep,
this will allow the sides, ends, and bottom, of slopstone to be 14" thick, see section F,
but thickness of sides &c. can be made as required.
The two side pieces marked A and B on plan No. 2 are made 2′ 01″ × 14″ × 34″
deep, the end piece C is made of two pieces of equal length fixed together in centre
by hinge, then join A B and C together with hinges as seen on plan No. 4. The
piece is made 1' 33" x 3" x 33" deep cut to pattern.
When these pieces A B C and D are placed in position the centre space is fitted
with board 111″ × 1′ 0″ × 1″ thick, this board marked E on plan No. 2 is fixed by
buttons screwed on board E and having made grooves in pieces A B C and D. Then
turn buttons round until at right angles with edges of E, the buttons having one end
each in grooves. E will be held firmly in position with the face or underside quite
level or flush with A B C and D.
A groove or mould must now be made on the top and outside edges of A B C and D,
to form the projection or rim on slopsione as shown at section F.
Then place this mould inside the large mould with board E upwards, and at equal
distance from each side and ends to be held in position with iron dowels or pins,
fixing two each in A B C and D, with holes to suit in board forming bottom of large
mould, dowels being tapered to allow of easy removal. Then fix pillar on board E
to form hole for waste pipe, in any position it may be required.
Mould is now ready for use, but care must be taken to see that the inner mould is
pressed closely down.
Then fill in material for slopstone until level with the edges of large mould.
Then with handle or mould (shown at section G) make recess for receiving waste
pipe, as seen at section F, and with mould shown at plan No. 6 and section H, cast
the lugs or projection for support of arm to fix the waste pipe. As soon as the
material is sufficiently set, the mould must be turned over when the outside mould
will slip off, leaving exposed the buttons as seen on plan No. 2, now turn all the
buttons paralell with edges of board E, which can then be lifted out by the handle,
then pieces A B and C can be moved forward as seen on plan No. 4 and taken out,
then take out piece D without any injury to slopstone or projecting rim.
