PROVISIONAL SPECIFICATION.
Improvements in and relating to Oinder Sifters.
I, ROBERT ORK TEMPLETON, of 164 Bothwell Street, Glasgow, Lanarkshire,
Cabinetmaker, do hereby declare the nature of my invention to be as follows :-
This invention consists of a new or improved construction of portable and self
contained mechanism or sifter for separating the cinders from the dust and ashes of
domestic and other fires for saving and reburning the same, and which is more
simple in construction and action than such siftors have been as horetofore
constructed.
The improvements consist in making an outer case preferably of rectangular
shape close on all the sides and bottom with a loose vertical flanged or recessed
top having cloth or like material secured round the inner edge surface to prevent
the escape of dust. This box contains the whole mechanism and would be of a
size to form a stool or other convenient sent, and might be either formed of wood
lined inside with sheet metal or be made wholly of galvanized iron, and would be
fitted with handles at the ends so as to form a box for containing and carrying
away the ashes. Inside of this box near the top would be mounted a shallow
movable strong framed portable tray say a few inches in depth opon at top and
formed with an open wire cloth bottom having an open mesh of about one quarter
of an inch or so, to let through all the dust but retain tho cinders on the top, out
of which any stone material that would not burn, could be easily removed by
hand. The tray might also have handles on it for removing it from the box with
the cinders and placing them on the fire. This tray, which I term the sifter tray,
would fit the width of the box loosely, but would be made only half the length or
so of the box, to allow it to reciprocate or oscillate freely in the longitudinal
direction in any of the following ways:-By one arrangement the tray may slide
on laths under it, or have wheels mounted on its under side to roll on the laths,
and have a plate at the one end with a narrow slot hole in it, into which the end of
a rod of similar shape would pass through a small hole in the side of the box, with
a handle outside, so that when the spindle was turned round in the hole in the tray
it would be locked and the tray would then be reciprocated by the handle outside
and so sift the cinders and ashes previously placed in the reciprocating tray, the
lid being put on the outer tray to prevent the escape of dust while sifting. By
another arrangement instead of mounting the sifting tray to reciprocate on side
laths, it might have small lateral motal projections fitted on its sides near the ends,
and which projections would be mounted in recessos in a small metal rocking bar
or frame fitted on each side of the box, and hung or supported on oscillating or
rocking levers Doar the ends of the bars. And instead of reciprocating or
Oscillating the tray from the outside by a handle direct a small rotating trans-
verse crank shaft might be mounted in journal bearings near the one end of the
box, the crank being connected by a rod or link to a joint pin under the opposite
end of the tray frame, the crank shaft being turned by a crank handle outside
shipped on to a square projecting end of the spindle.

Improvements in and relating to Oinder Sifters.
I, ROBERT. OBR TEMPLETON, of 154 Bothwell Street, Glasgow, Lanarkshire,
Cabinetmaker, do hereby declare the nature of my invention, and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement in writing, that is to say :--
This invention consists of a new or improved construction of portable and self-
contained mechanism or sifter for separating the cinders from the dust and ashes of
domestic and other fires for saving and roburning the same, and which is more simple
in construction and action than such sifters have been as heretofore constructed.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood I have hereunto
appended an explanatory sheet of drawings in which the same reference letters are
used to indicate corresponding parts in all the figures where shown.
Figures 1 and 2 are longitudinal and transverse sections as taken on the lines 1-1
and 2-2 respectively on the plan view Figure 3, of a cinder sifter as constructed
in accordance with one arrangement of my improvements.
Figure 4 is a detached view of the portable spindle for actuating the cinder
tray:
Figures 5.and 6 are longitudinal and transverse sections, corresponding to
Figures 1 and 2, showing how the cinder tray may be mounted to vibrate on links
instead of reciprocate on laths as in Figures 1 to 3. While
Figure 7 is a plan view broken away corresponding to Figure 3 showing how tho
vibratory motion may be given to the cinder tray by a crank shaft and link.
Referring to these drawings:-The improvements consist in making an outer
case A preferably of rectangular shape close on all the sides and bottom, and with
a loose vertical flanged or recessed lid or top A', having cloth or like material A",
secured round the inner edge surface to prevent the escape of dust. This box A
contains the whole mechanism and would be of a size to form a stool or other
convenient seat, and might be either formed of wood, liued inside on the bottom or
botton and sides with sheet metal, or be made wholly of galvanized iron, and would
be fitted with handles A', at the ends so as to forin a box for coutaining and carrying
away the ashes. Inside of this box near the top would be mounted a shallow
movable strong framed portable tray B, say a few inches in depth open at the top
and preferably lined on the inner surface of the sides with sheet metal, and formed
with an open wire netting or wire cloth bottom b having an open mesh of about one
quarter of an inch or so, to let through all the dust but retain the cinders on the
top, out of which any stone material that would not burn could be easily removed
by hand. The tray B, might also have handles on it for removing it from the box
with the oinders and placing them on the fire. This tray B, which I term the
sifting tray; would fit the width of the box loosely, but would be made only half
the length or so of the box A, to allow it to reciprocate or oscillate freely in the
longitudinal direction in any of the following ways:— -By one arrangement as shown
in Figures 1 to 3 the tray B may slido on laths A' under it, fitted on the inner
surface of the sides of the box A or have wheels &* mounted on the under side of the
tray B as shown, to roll on the laths A'. A plate a is fitted at the one end of the
tray B with a narrow slot hole in it, into which the end of a spindle or rod a',
detached in Figure 4, of similar shape would enter after first passing through a small
slotted hole in the end of the box A; and this spindle a' would be formed with a
handle a outside, so that when it was turned a half revolution round in the hole a
in the tray B its inner end all would be locked and the tray B would then be
reciprocated along the laths A' by the handle a' outside, and so sift the cinders
and ashes previously placed in the reciprocating tray B, the lid A¹ being put on the
outer box A to prevent the escape of dust while sifting. By another arrangement,
as shown in Figures 5 and 6 instead of mounting the sifting tray B to reciprocate
shown

page_text: on side laths A³, it might have small screw pins or lateral metal projections 6' fitted
on its sides near the ends, and which projections would be mounted in recesses in
emall metal rocking bars or a frame, fitted on each side of the box and hung or
supported near the ends of the bars, on adjustable screw pins &" or it might be
on oscillating or rocking levers and which when the handle a' is worked would
shake the tray B to sift the cinders in it. Instead of reciprocating or oscillating the
tray B from the outside by a handle a' direct, as shown in the plan view Figure 7,
a small rotating transverse crank shaft c might be mounted in journal bearings near
the one end of the box A, the crank e being connected by a rod or link c' to a
joint pine, under the opposite end of the tray frame B, the crank shaft e being
turned by a crank handle c" outside shinned on to a square projecting end of the
