COMPLETE SPECIFICATION.
I JOSEPH HAMBLET of Piercy Brick Works, West Bromwich in the County of
Stafford, Brick and Tile Manufacturer do hereby declare the nature of my Invention
for "IMPROVEMENTS IN DIES AND MACHINERY FOR THE MANUFACTURE OF RIDGE
TILES AND OTHER ROOFING TILES" and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :-
My invention has reference principally to dies and machinery for the manufacture
of ridge tiles but part of my invention as herein after explained may be used in
the manufacture of ordinary roofing tiles and the roofing tiles called "hip" and
'valley" tiles.
I will describe my invention as applied to ridge tiles. The vertical part or that
part projecting from the summit of the ridge tile is ordinarily ornamented at its
edges and pierced with various ornamental patterns by hand by the use of a
wooden pattern or template. My invention consists in cutting the edges and
piercing the vertical part of the ridge tile at one blow or operation by means of
dies constructed and operated as herein after described.
I make the moveable die of a strong base plate to the underside of which a
cutting edge made of sheet metal is affixed, the said cutting edge having the figure
of the edge of the ridge tile to be shape.l. I also attach to the base plate other
cutting edges of a figure proper to form the ornamental piercings in the ridge tile.
These last named cutting edges are hollow or tubular and are fixed over openings
in the base plate so that the clay cut out by them escapes through the said base
plate. The said die works through a fixed stripping plate having the same con-
figuration as the die. By means of this stripping plate the dio is prevented from
carrying the tile with it in its rising motion.
I actuate the moveable die described by means of machinery constructed as
follows: The said die is affixed to the bottom of a vertical slide or bolt working
in guides in the framing of the machine. The said slide or bolt is raised and
lowered by means of a pinion working in a rack on the slide. The said pinion is
rotated by means of a combination of levers worked by a treadle When the
treadle is pressed down a descending motion is communicated to the slide or bolt
and the die carried by it, which die operating upon the unburnt tile supported
upon a fixed flat die on the bed of the machine cuts the edges of the vertical part
of the ridge tile and at the same time and by the same operation pierces the
required ornaments in it. On removing the foot from the treadle the slide or bolt
is raised by a weighted lever and the die lifted from the shaped and ornamented
tile, the fixed stripping plate herein before described preventing the tile being
carried with the die.
The body part as well as the vertical part of ridge tiles may be shaped and
ornamented by the use of the dies and machinery described.
By substituting for the moveable and fixed dies described other dies, the machine
may be used for "horsing" ordinary roofing tiles, that is, giving a slight convex
figure to the tiles and also for fashioning or completing the figure of "hip" and
valley" tiles.
The machine may be worked either by manuel power or by steam or other

page_text: Figure 1 represents in side elevation and Figure 2 in front elevation machinery
constructed according to my invention for the manufacture of ridge tiles and other
roofing tiles, with the bolt or slide of which machinery a moveable die is combined
the said dio being also constructed according to my invention for cutting the edges
and piercing the vertical part of ridge tiles. This die is shown detached in side
elevation and plan of underside, drawn to the samo scale as the machine, in
Figure 3. The said die is also shown partly in section drawn to a larger scale in
combination with a portion of the machinery in Figure 4 and detached in plan of
underside and cross section in Figure 5.
Figure 6 represents a side elevation of one of the ridgo tiles before it has been
operated upon by the machine and Figure 7 represents the same after the vertical
part of the said tile has been pierced out and its edge ornamented.
The same letters of reference indicate the same parts in the several Figures of
the drawings.
I will first describe the construction of the moveable die: a is the strong base
plate of the die to which base plate a the carrying plate a³ is affixed the latter
having secured to it the sheet metal cutting edges b and c. The cutting edges
marked b, b have the figure of the edge of the ridge tile to be shaped and the
cutting edges marked c, c, which are hollow or tubular, are for the purpose of
forming the ornamental piercing in the ridge tile. The cutting edges b and c are
furnished with ears d, d by means of which the said cutting edges are secured by
the screws e to the under face of the carrying plato a² and to the strong base
plate a of the die as best seen in the plan and section Figure 5. The hollow or
tubular cutting edges c, c are situated under an opening f, of the same configuration,
in the base plate a and carrying plate a³ (see Figures 4 and 5). Through this
opening the clay cut out by the cutting edges c, c escapes into the space between
the base plate a and the parallel upper plate a³ by which the die is connected to
the slide or bolt of the machine; g is the fixed stripping plate on the bed of the
machine the said stripping plate having the same configuration as the cutting
elges b and c of the dic. Through this stripping plate g the die works and by
its use the die is prevented from carrying the tile with it in its rising motion.
I will now describe the construction of the machinery: is the fixed flat dio on
the bed of the machine on which die the vertical part i of the ridge tile is
supported, one of the angular parts of the body of the tile being supported on the
outside bracket as seen in Figures 1 and 4.
The moveable cutting and shaping die constructed as herein before described is
affixed by screw bolts at m to the bottom of the vertical slide or bolt n working in
guides carried by the framing 2 of the machine. The said slide or bolt n is
actuated by means of the ruck π² on its inner face with which rack a pinion n³
gears. This pinion is rotated through the angle necessary to raise and lower the
slide n, and the die carried by it, the required distance by means of the lever p the
inner end of which is fixed on the axis of the said pinion n³ and the outer end
carries a weight not represented. The weighted lever p is connected by the
On pressing
adjustable connecting rod g to the inner end of the treadle lever r.
the foot upon the treadle plate of the treadle lever a descending motion is
communicated through the rod q, lever and pinion and rack n³, n² to the slide n
and the die carried by the said slide, which die operating upon the plastic tile
supported in the manner shown in Figures 1 and 4 cuts the edges of the vertical
part of the tile and also pierces the required ornament in it as represented in the
finished tile Figure 7.
After the dio has operated upon the tile the foot of the workman is removed
from the treadle plate when the slide or bolt n is raised by the weighted lever p
and the die lifted from the shaped and ornamented tile, the fixed stripping plate g
preventing the tile from being carried upwards with the die.
Figure 8 represents in plan of underside and Figure 9 in vertical section a die
constructed according to my invention for cutting out the clay blanks for the
manufacture of hip and valley tiles; Figure 10 represents in plan and side

page_text: elevation the sliding stripping plate of the die detached; Figure 11 represents a
front elevation of part of the machine in which the cutting die Figures 8 and 9 is
used: a is the base plate of the die to which plate the cutting edge s' is affixed by
the ears and screws at 83. The cutting edge & has the configuration best seen in
Figure 8. Within the cutting edge s² of the die a moveable or sliding stripper
plate t works. This stripper plate t has the same configuration as the interior of
the cutting edge & as seen in Figure 10 and its upper side is furnished with
connecting scrow pins u by which it is secured to the base plate of the die by
means of screw nuts screwed on the screwed ends of the said pins as seen in
Figure 9. The stems of the screw pins u work through holes in the base plate 8.
By means of coiled springs x, x around the screw pins u bearing at bottom against
shoulders on the said screw pins and at top against the underside of the base
plates of the die the stripper plate t is preserved in the normal position shown in
Figure 9, that is, at the bottom of the cutting edges 8³, 8³.
The cutting out die Figures 8 and 9 is fixed by screw bolts at w, w to the
bottom of the slide or bolt n of the machine which slide is actuated in the
manner herein before described with respect to the slide used for working the die
Figures 3 and 5.
The bed of the machine Figure 11 is recessed at y. In this recess the receiving
board or table y is placed on which the piece of clay z, from which the blank is to
be cut, is supported as represented in Figure 11. On the descent of the die 8, 82
its edge cuts out the blank from the piece of clay 3, the stripping plate t passing
into the die and compressing the springs as the acting edges enter the clay. As
the die 8, 8² is lifted from the bed of the machine the springs hold the cut out
blank on the receiving table y until the cutting edge a² is withdrawn from it.
The cut out blank is thereby prevented from being carried upwards with the die.
By fixing to the bolt or slide n of the machinery represented in the drawings,
moveable dies of the required shape, the machine may be used for cutting out blanks
for the manufacture of roofing tiles and for shaping and fashioning roofing tiles
other than those in connection with which I have described it.
When the machine is worked by steam or other motive power in place of manual
labour, the lever r, which I have called the treadle lever, is operated upon by a cam
or other like mechanical appliance from the motive power engine.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is

and other roofing tiles herein before described and illustrated in Figures 1, 2, 3, 4,
6, 8, 9, 10 and 11 of the accompanying Drawings; that is to say, making the
acting or cutting or piercing edges of the said dies of sheet metal fixed to a base
plate, the said dies being used in combination with a fixed stripping plate or
with a stripping plate sliding within the die substantially as described and
illustrated.
Secondly-The improvements in machinery herein before described and illus-
trated in Figures and 2 of the accompanying Drawings to bo used in the
manufacture of ridge tiles and other roofing tiles; that is to say, actuating the
