Improvement in Cinder Sifters.
I JOHN URIAH DAVIS of 133 Clapham Road London S.W. Sanitary 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 :-
This invention relates to the construction of cinder sifters, and may be described
as follows.
Fig. No. 1 drawing shews back elevation of colapseable tressel with taper cinder
sifter box, mounted with pivots. Iron hooks are screwed on edge of tressels,
at convenient position the box is hung or suspended in tressel. Upon opening the
tressel the box can be held in any position or will rest on rail at A. as shewn at
Fig. No. 2. which is side elevation of sifter, and when in that position, the box
Fig. No. 2, can be readily filled with cinders, the box and cinders is supported on
the four legs of the tressels.
Fig. No. 4 is a section thro' in Fig. No. 2 B C, D Fig. No. 4. shews wire work
formed with any desirable mesh, or can be formed with stamped metal, with holes
of various shapes, and is fixed in box with double fillets, or groove in centre of
fillet, to fit the wire work, or stamped plate, or can be nailed on one fillet, as may
be convenient, and can be fixed at any angle, below the wire work, a thin board,
or metal plate, E, is fixed on fillet of wood, or grooved out to fit board, or plate,
as may be desired. The board or plate is fixed in a slanting direction, as shewn
or any desirable angle, so as to allow enough room for the ashes to fall through
at F, at G a lid is formed, of suitable size, and hinged to top at H, Fig. No. 2,
a suitable fastening is provided which keeps the lid firmly closed, after the sifter
is filled, it will be noticed that the box at J, is projected out to any suitable angle,
to form opening in side of box, the lid is hung on hinges, and suitable fastening,
as at H 1, Fig. No. 4, the box, or sifter, as shewn at Fig. No. 2, being filled, with
cinders, and fastened at H 1, and J, the operator, either with double hook handle, I
Fig. No. 1. or lever P, Fig. No. 6, gives the sifter, a push and pull motion, this
jerky motion soon seperates the ashes from the cinders through the meshes of the
wire work or stamped plate D the sifted ashes slides off the slanting board or plate to
the bottom of the box, as soon as the cinders are seperated from the ashes the lid
at H 1, is opened, and the box is held in position, with H 1, at its bottom part, the
cinders can then be shook out, but leaving the sifted ashes at the top of the box,
as the box is now reversed the slanting board or plate acts as a baffle to prevent
the ashes coming out the same way that it went in at H 1 and is only to be
readily removed through lid at J, now it will be seen that the cinders can be
removed without disturbing the ashes, or the ashes can be removed without
disturbing the cinders, or either cinders or ashes mixing together again, Fig. No. 3
is colapsable tressel, and sifter shewn when not in use, a cord or chain or strap is
used at L to keep the tressel spreading beyond the required distance and is fastened
to diagonal braces at bottom shewn at M. The tressel at N is bolted together
with head and nut. The sifters can be used seperate from the tressels, as bow
handles are provided with double hooks formed on at each handle, to these are
attached cords or chain or strap at the end of cord or chain a hook, is fastened,
the box can then be suspended at any convenient height, the box is then well
shaken, which effects the sifting, in this system, side handles are provided for
convenience of handling; Fig. No. 5 is front elevation, of sifter, with colapsable
tressel, the sifter, hung on pivots. The pivots are screwed to side of box, the
bottom of tressel, is held together, with thin solid boards, at O, it will be seen
that the pivots are fixed in the centre of sifter. The push and pull motion is given

page_text: as described at No. 2, a lock action lever, is used for this purpose. A plate is
formed with hooks, a portion in centre is cut out to receive lever. The lever
has a centre portion that fits between hooks and has projecting pins, on each
side, the lever is raised up, and the front pins, are engaged in hooks, the lever
is then lowered down by doing so, the two back pins on lever, passes close to
back of hooks, when in this position it is ready for use, and is locked to hooks,
until the lever handle is raised to relieve the pins, from hooks this is shewn
at Fig. No. 6, at P, Fig. No. 7 is section through Fig. No. 6 on drawing thro'
line Q R.

lid B 2 can be closed or left open as shewn, and supported open with hook and eye
fastening, on the bottom of sifter, wire work, or stamped plate, of any suitable
mesh is fixed and in large sizes, is strengthened with suitable flat iron bars, to keep
the wire from saging. The sifter, being in position for use shewn at D 2. the
operator commences to use Fig. No. 46, this rod, or bar, can be used at any con-
venient distance from the sifter, a iron plate is fixed on body of sifter, as shewn
at E 2, the point of Fig. No. 46, or 48, the top point is put through the oblong
hole at E 2, and is turned round at right angles to the oblong hole in plate
quick push and pull motion is given, this immediatly shakes the cinders and
seperates the ashes from the cinders, as soon as complete the cinders, can be
tipped out and the sifter, is ready to be refilled, as shewn at Fig. No. 51.
Fig. No. 47 shews plan, and section of iron plate fixed at E 2.
a
Fig. No. 50, shews form of iron hook, used to suspend sifter, it will be seen that
a short piece of pipe is used between hook and inside tressel this keeps the sifter,
from working against tressel.

shape and can be made in wood or iron.
Fig. No. 53 is section thro' F 2 F 2 in Fig. No. 54 the wire work for sifting is
intended to be same as described with slanting board or plate the box is constructed
with lids back and front as shewn with hinges and suitable fastenings the cinders
and ashes can be removed seperatly, as described wheels are provided and fixed in
front as shewn with or without india rubber tyers, and the axles as have been
described, the sifter can be suspended either with single or double cords, also
chains, strap or pivotted on colapsable tressel, the front handles can be omitted.
Fig. No. 55 is front view of sifter.
Fig. No. 56 is section through J 2. K 2 of sifter and is provided with wire work,
with suitable mesh at G 2 a slanting board or metal plate is fixed below wire work
at suitable angle, and distance lids are hung at H 2. J 2. H 2 to receive cinders for
sifting J2 is hung to remove ashes from sifting. Fig. No. 59 shews side elevation.
It will be seen that the box as suspended from cross rail of framing either with
cords chains or rods connects at the top part with bolt and eye formed for fastening
at the bottom ends of cords or chain or rods bolts are formed with eyes, and are
passed through cross rails, the rails now form a position to swing or suspend the
box or receptacle, in the middle of the rails a forged iron bearing is fixed shewn by
dotted lines, Fig. No. 57, and screwed to rail, a portion of the wood rail is cut
away, to receive end of axle, shewn at Fig. No. 58, which is larger in diameter
than the axle working on iron bearing a strap iron is fastened at the other end of
axles with suitable screw holes and is screwed on sides of sifter shewn at Fig. No. 58,
it will be seen that this keeps the rails K 2. at even distance from end of sifter, a
loose washer can be employed between strap, and bearer, to prevent wearing of
wood, at head of axles, two handles of any suitable shape is fixed on sides of
sifter the operator will now give a push and pull motion to the sifter, and a further
upset will take place upon his lifting or bearing down the handles as the box will
now be working on the axles this will facilitate the sifting, suitable framing is
constructed to suit any size sifter and wheels can be added to facilitate the
moving.

the removal of ashes.
Fig. No. 64. shews section with double slanting boards or plate B 2 dotted lines
shew wire work or plate A 2. with any suitable mesh or hole. The object of
double slanting boards or plate is to obtain as much space as possible for ashes and
in this form to obtain an irregular shaped box, for the cinders, this facilitates
sifting. This sifter can be used swinging with cord, chain, or strap, and fitted with
double hook handles or push and pull motion with rod or bar, or used with one leg,
and ball support, or two legs can be employed in large sifters, iron ball is prefer-
able, this sifter can be made in any suitable size, or form, in wood or metal.
Fig. No. 65, shews section of sifter. It will be seen that the double slanting
board, or plate, is portion of the outside of box. The construction of sifter, is to
give as much room for cinders as possible, A 3 dotted line shew wire work or plate
