This invention relates to a machine for sanding moulds for use in brick making,
in which a rotary sanding cylinder, having a chamber for holding sand and a series
of three or more. mould receiving openings provided in its periphery operates to
receive the moulds to be sanded, and hold such-moulds in such a relation to each
other, that when one or more of said moulds is or are down below the plane of
centre of rotation of the cylinder and receiving the sand, one or more other moulds
will be carried upward above the said plane centre of rotation, and be emptied of
sand and be in convenient situation for ready removal and replacement; and also
in which an elastic supporting bed, supported wholly from the frame of the
machine operates in conjunction with the said sanding machine to automatically
hold the moulds in place in the mould receiving openings, made in the periphery of
Baid cylinder.
The objects of my invention are as follows viz, First. To provide in a machine
for sanding moulds for brick, a rotary sand containing box or cylinder which will

page_text: C
be provided in its periphery with a series of mould receiving openings, whereby
sand may be readily supplied to the said cylinder, and moulds placed in the said
openings will be made to close the cylinder and retain the sand when the cylinder
is revolved, and when carried below will become filled with sand, and when carried
above will be emptied of sand with a portion of the same adhering to the surfaces
of the sides of the moulds.
Second. To provide in a brick mould sanding machine a sanding box or cylinder
which is adapted to be revolved with a series of two or more oppositely disposed

upward to be emptied of sand, and be brought successively to an inverted position
for convenient removal and replacement of the same without stoppage of the
cylinder.
Third. To Provide in a brick mould sanding machine a rotary sanding box or
cylinder which has its periphery formed with a series of equal fixed side portions
or staves and provided with equal mould receiving openings, whereby said sand
cylinder will be adapted to receive a series of moulds successively between said
fixed side portions and staves, so that when one or more moulds is or are carried
downward below the plane of the centre of their rotation they will be successively
filled, while at the same time the moulds being carried up will be emptied for
removal, to be replaced by others at the will of the operator.
Fourth. To provide, in a machine for sanding moulds, a rotating sanding box or
cylinder having mould-receiving openings, mechanism for automatically retaining
the moulds and releasing them when sanded for their ready removal from the

wholly supported from said frame and made to have an upward bearing against
the lower portion of the periphery of said cylinder and the moulds which are
relatively below the plane of the centre of their revolution, and mechanism for
revolving said cylinder, whereby the moulds will be revolved with the sanding
cylinder uniformly and be successively carried about the centre of their revolution,
and when below a line on a plane with said centre they will be firmly held in
place while being filled with sand, and be progressively moved to a higher plane
and emptied of sand and released for removal at the will of the operator.
Fourteenth. To provide in a brick mould sanding machine, the combination
with a supporting frame and a rotary sanding box or cylinder having a series of
openings made equi-distant apart in its periphery for receiving moulds inter-
changeably, of endless running bands, or their well known equivalents so arranged
in connection with the supporting frame, and in relation to the sanding cylinder,
that the said bands will bear with elastic force against the lower portion of the
periphery of the cylinder and bottoms of the moulds successively as they are
revolved.
•
Fifteenth. In a machine for sanding moulds for brick the combination with the
supporting frame and revolving box or cylinder having its periphery formed with
alternate fixed side portions or staves, and mould receiving openings, of a system
of pulleys and endless running bands which are made elastic by the action of
gravity exerted on said bands, whereby the said bands will be made to conform to
all relative inequalities attending the surfaces of the periphery of the cylinder and
backs of the moulds as they are revolved.
In carrying the said Invention into practice I provide framework which may be
made of wood or iron, or both combined as may be desired. Supported in bearings
fixed to this frame is a revolving shaft. Mounted on a shaft and secured thereto
so as to revolve with it a sanding cylinder or box is provided designed to contain
the sand to be applied to the interior of removable moulds. This sanding box is
preferably made rectangular in form, though it may be made cylindrical if preferred

page_text: and consists of end heads and staves securely united together by bolts, rivets or
screws as may be preferred; it is made with a length from head to head (inside
measure) equal to the length of the removable mould intended to be sanded, while
its diameter may be varied according as the capacity of the box or cylinder for
holding moulds may require. Made in the periphery of this sanding, cylinder or
box are mould receiving openings which openings are each made with a width equal
to the width (outside measure) of the removable moulds said openings are to
receive.
The sanding cylinder may be provided in its periphery with four equal mould
receiving openings. This number of said openings is not essential, as their number
may be lessened to two, or increased to six or eight, as may be preferred, provided
said openings are so arranged in relation to each other that at least one opening
will be above while another will be substantially below. The interior of said box
or cylinder forms the sand chamber.
Secured to, or made with, the inner and oppositely located or facing edges of
staves are ledges or flanges the upper sides of which are on a plane with the
exposed edges of the head of the sanding cylinder. These flanges project into the
mould receiving openings to a distance preferably about equal to the thickness of
the sides of the removable mould and they serve to support the side edges of these
moulds and seal the joint between the sides of the same and the edges of staves
against the escape of sand from the sand chamber.
Secured to the shaft is a gear wheel which gear wheel is actuated by a pinion
mounted on a counter shaft; loosely mounted on this counter shaft is a band wheel
which has made with one of its hub ends a clutch-gear, a loose clutch held from
turning by a feather or spline is also mounted on the countershaft and is operated
by a hand lever for throwing the same into engagement with the teeth of the
clutch-gear made with the band wheel, or the reverse; motion is communicated to
the sanding cylinder through the said gear wheels and band pulley. If preferred
band wheels and a band may be substituted for the gear wheels.
Supported from the frame in proper bearings are shafts in which are mounted
pulleys; pivotted from one of the lower shafts are horizontal arms, the outer
ends of which have mounted in them shafts, on which shafts are mounted pulleys.
There are endless bands, made preferably of india-rubber so as not to be affected
by dampness. These bands are made with a width of about four inches, preferably,
and with a thickness of about a quarter of an inch, and are supported from pulleys
and are so arranged in relation to the sanding cylinder that their upper portion
will run downward from the upper pulleys and around and against the lower side
of sanding cylinder and thence each way down from the upper pulleys to below
the lower pulleys and horizontally beneath the portions of the said band bearing
against the sanding cylinder. A weight laid across from one to the other at or
near their outer or swinging ends, will operate to cause the tension of the bands
to be always the same, and be made thereby to exert an elastic pressure against
the lower side of the sanding cylinder.
These endless bands form a supporting bed which has an elastic bearing against
the lower portion of the peripherial surface of the sanding cylinder and the backs
of the removable moulds when said moulds are below. They operate as an elastic
mould retaining mechanism which is adapted to hold the moulds securely in place
in their respective openings when they are below the plane of the centre of
rotation of the sanding cylinder, with the sand resting on or within said moulds.
They also operate to automatically hold the moulds with the sanding cylinder,
when below and release them for ready removal and replacement by others, when
they are above the plane of the centre of rotation of said cylinder.
When the sanding cylinder is revolved with its lower side moving in contact
with its elastic bed, motion will be given to the bearing surface of said bed and it
will be made to move in unison with the outer surface of the cylinder and the
moulds as they are being revolved, without the surfaces of either the cylinder or

page_text: moulds in contact being worn, as this elastic bed will conform to the inequalities of
the surface of the moulds and cylinder, they are in contact with, and will move in
unison with those surfaces, there will be no jarring or pounding of the parts.
This mould supporting mechanism or elastic bed, being supported wholly from
the frame, obviates the necessity of employing other mechanism attached to the.
sanding cylinder, for holding the moulds in place while they are receiving the sand.
The machine is driven by a belt or band running from the band pulley to a
driving pulley or wheel, driven by any convenient motor, the sanding cylinder is
so speeded in its revolution in relation to the speed of the brick forming machine,
that the opening will be brought up to be at a top corner, or to its highest point
at the top side of the cylinder once at each discharge of a filled mould from the
brick forming machine it is to sand moulds for; so that a sanded mould will be
carried up to be in situation for ready removal simultaneously with the discharge
from the brick moulding machine of a filled mould therefrom. If the brick
moulding machine is run with a speed to make it discharge, say twelve filled
moulds in each minute, the sanding cylinder when provided with four mould
receiving openings is to be revolved with a speed of three revolutions a minute.
The moulds to be sanded are to be first wet within in the usual manner for
causing the sand to adhere. The mould receiving openings, except one, are to be
successively covered by a removable mould (placed in an inverted position) over
said openings with their side edges resting on the flanges. This is conveniently
accomplished by the operator placing over the openings an inverted mould and then
reversing the sanding cylinder until said opening is carried down to another
position when an opening will be carried to another position and will be covered
by the second mould, and by a further revolution the first placed mould will be
carried back. When these three openings are thus closed by the moulds, sieved
and clean sand slightly moistened will be introduced into the cylinder until it is
filled from about one third to about one half full, when the machine will be in
readiness for continuous operation.
An operator, standing at the rear of the machine, will then place a mould over
the remaining unclosed opening, the cylinder to be continuously revolved, when
the sand within the cylinder will be tumbled about within the cylinder and be
cast into each mould successively as it is brought down to the proper positions
and be emptied of sand successively as it is carried to another position, when
the operator will give the mould a slight rap and remove the same to any con-
venient table or other place for its ready placement in the brick moulding machine.
Another operator standing in front of the machine facing an opening will (as
each opening uncovered by the first operator by the removal of a mould is carried
to another position of opening) place a mould (from the moulds which have been
returned emptied of moulded brick) over such opening when it will be carried
progressively downward, and be filled with sand and then upturned and emptied
of sand and removed by the first mentioned operator. Thus the two operators
will attend the machine, one to remove the sanded moulds for their replacement
in the brick forming machine, and the other to replace the moulds as they are
returned after the moulds have been emptied of their moulded brick; the moulds
will be sanded uniformly on every portion of all their sides and ends, without
any sand adhering to the outside surfaces of the moulds, and without any waste of
sand.

Similar letters of reference indicate corresponding parts in the several figures
A, A indicate the frame work of the machine which frame work may be made
of wood or iron, or both combined as may be desired. Supported in bearings a, a
fixed to this frame is a revolving shaft B; mounted on the shaft B and secured
thereto so as to revolve with it, is the sanding chamber C designed to contain the
.sand to be applied to the interior of the removable moulds M This sanding
chamber is preferably rectangular in form, though it may be made cylindrical if
preferred; and consists of end heads b, b and staves c, c securely united together
by bolts, rivets or screws as may be preferred; it is made with a length from head
to head (inside measure) equal to the length of the removable mould M intended
to be sanded, while its diameter may be varied according as the capacity of the
box or cylinder for holding moulds may require. In the periphery of this sanding
cylinder or box are mould receiving openings D, D which openings are each made
with a width equal to the width (outside measure) of the moulds M the said
openings are to receive.
The drawings show a sanding cylinder provided in its periphery with four equal
mould receiving openings D, this number of the said openings is not essential, as
it may be lessened to two, or increased to six or eight, as may be preferred,
providing the said openings are so arranged in relation to each other that at least
one opening will be above while another will be substantially below. The interior
of said box or cylinder forms the sand chamber.
Secured to, or formed with the inner and oppositely located or facing edges of

into the mould receiving openings D to a distance preferably about equal to the
thickness of the sides of the mould M, and they serve to support the side edges of
these moulds and seal the joint between the sides of the same and the edges of the
staves c, c against the escape of sand from the sand chamber.
Secured to the shaft B is a gear wheel E which gear wheel is actuated by a

the teeth of the clutch-gear made on the band wheel G, Motion is communicated

page_text: to the sanding cylinder through the said gear wheels and band pulley. If preferred
band wheels and a band may be substituted for the gear wheels.
Supported from the frame A A in proper bearings are shafts 8, 8, 8 on which are
mounted pulleys H, H, H. Pivoted from one of the lower shafts 8, s are horizontal
arms I, I the outer ends of which have mounted in them a shaft s¹ on which are
mounted pulleys H¹. H¹.
J J indicate endless bands, made preferably of India rubber so as not to be
affected by dampness. These bands are preferably about four inches wide and a
quarter of an inch thick and supported upon the pulleys H, H, H, H' as shown.
The said bands are so arranged in relation to the sanding cylinder C that their
upper portion will run downward from the upper pulleys H H and around and
against the lower side of the sanding cylinder C and thence each way down from
the upper pulleys H, H, to below the lower pulleys H, H' and horizontally beneath
the portions of the said bands bearing against the sanding cylinder. A weight
laid across from one arm to the other at or near their outer or swinging ends as at
the pulleys H, H¹ will operate to cause the tension of the bands to be always the
same, and be made thereby to exert an elastic pressure against the lower side of

These endless bands form a supporting bed which has an elastic bearing against
the lower portion of the peripherial surface of the sanding cylinder and the backs
of the removable moulds when the said moulds are below, as shown in Figures
and 2 They operate as an elastic mould retaining mechanism which is adapted to
hold the moulds securely in place in their respective openings D when they are
below the plane of the centre of rotation of the sanding cylinder, with the sand
resting on or within the said moulds. They also operate to automatically hold the
moulds with the sanding cylinder, when below, and release them for ready removal
and replacement by others, when they are above the plane of the centre of rotation
of the said cylinder.
When the sanding cylinder is revolved, with its lower side moving in contact
with its elastic bed, motion will be given to the bearing surface of the said bed
and it will be made to move in unison with the outer surface of the cylinder and
the moulds as they are being revolved, "without the surfaces of either the cylinder
or moulds in contact being worn. As this elastic bed will conform to the inequalities
of the surfaces of the moulds and the cylinder, they are in contact with, and
will move in unison with those surfaces, there will be no jarring or pounding of
the parts.
This mould supporting mechanism or elastic bed, being supported wholly from
the frame, obviates the necessity of employing other mechanism, attached to the
sanding cylinder, for holding the moulds in place while they are receiving the
sand.
The operation of the machine is as follows, that is to say :-
The machine is driven by a belt or band running from the band pulley G to a
driving pulley or wheel driven by any convenient motor, the sanding cylinder is so
speeded in its revolution in relation to the speed of the brick forming machine,
that an opening D will be brought up to be at a top corner, or to its highest
point at the top side of the cylinder, once at each discharge of a filled mould from
the brick forming machine it is to sand moulds for; so that a sanded mould will
be carried up to be in situation for ready removal simultaneously with the discharge
from the brick moulding machine of a filled mould. For example if the brick
moulding machine is run with a speed to make it discharge, say twelve filled
moulds per minute, the sanding cylinder (when provided with four mould receiving
openings) is revolved with a speed of three revolutions a minute.
The moulds to be sanded are first wetted within in the usual manner for
causing the sand to adhere thereto. The mould receiving openings D except one
are successively covered by a mould M (placed in an inverted position) over
the said openings with their side edges resting on the flanges f. f. This is

page_text: conveniently accomplished by the operator placing over the opening D' an inverted
mould and then reversing the sanding cylinder in the direction of the arrow N° 1
in Figure 2 until the said opening is carried down to the position D2, when the
opening at D will be carried to the position of the opening at D' and will be
covered by the second mould, and by a further revolution the first placed mould
will be carried back to the position D³. When these three openings are thus
closed by the moulds M, sieved and clean sand slightly moistened is introduced
into the cylinder until it is filled about one-third to one-half full, when the
machine is in readiness for continuous operation.
An operator, standing at the rear of the machine then places a mould over the
remaining unclosed opening (the cylinder to be continuously revolved) when the sand
within the cylinder will be tumbled about and cast into each mould successively as it
is, brought down to the positions D³, D³, and be emptied from each mould successively,
as it is carried to the position D2 when the operator will give the mould a slight rap
and remove the same to any convenient table or other place for its ready placement in
the brick moulding machine. Another operator, standing in front of the machine
facing the opening at D' will (as each opening uncovered by the first operator
by the removal of a mould is carried to the position of the opening at D¹) place a
mould (from the moulds which have been returned emptied of moulded brick)
over such opening, when it will be carried progressively downward, and be filled
with sand and then upturned and emptied of sand, and removed by the first
mentioned operator. Thus the two operators will attend the machine, one to
remove the sanded moulds for their replacement in the brick forming machine,
and the other to replace the moulds as they are returned after they have been
emptied of their moulded brick; the moulds will be sanded uniformly on every
portion of all their sides and ends, without any sand adhering to the outside
surfaces of the moulds, and without any waste of the sand.
Having thus fully described the said invention as communicated to me by my
foreign correspondents and the manner of performing the same I wish it under-
stood that I claim-
