Specification Accepted, 14th June, 1887.
We, FRANK KOHLER, Engineer, and WILLIAM A. CHAMBERS, Gentleman, both of
417 Olive Street, in the City of St. Louis, State of Missouri, United States of America,
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:
Our invention relates to an improvement in malt kiln dumping floors and has for its
object to enable the floors to be dumped more easily and effectively than can be done
with the dumping floors in present use and to simplify and cheapen the cost of their
construction.
It consists in hinging the various sections of the floor at one or other of their end
corners and effecting the dumping and raising again of the sections from and to the
horizontal position by the reciprocation of vertical tappet and supporting arms carried
by longitudinal bars beneath the floor.
°
On the accompanying drawings Figure 1 is a plan representing the general
arrangement of our improved malt kiln dumping floor partly broken away. Figure 2
a side elevation to an enlarged scale of a portion of the floor taken for example on
line 11 in figure 1. Figure 3 a plan of figure 2. Figure 4 a similar view to
figure 2 showing the floor dumped. Figure 5 a plan of figure 4. Figure 6 an end
view of a portion of the floor taken on line 22 in Figure 1, with brickwork removed.
Figure 7 a side elevation to an enlarged scale of a portion of the floor taken at
line 33 in figure 1 showing the dumping gear, and Figure 8 a plan thereof; like
letters of reference denoting like parts in all the figures.
A A represent the various sections of our improved dumping floor which may
comprise one, two or more complete series of sections A according to the area or
capacity of floor required. Each section A is composed of two end pieces B arranged
parallel with each other and with the sides of the floor and connected by bars and
angle irons so as to form an open rectangular frame-work which is covered by perforated
sheet iron or wire cloth C.
From the outside of each end piece B at one of its corners, or as shown on the
drawings, at its extreme left hand top corner projects a pivot, pin or stud D whereby

page_text: cach section A is mounted or hinged in bearings E attached to the two side bars F of
the floor.
Beneath the sections A at a suitable distance therefrom and from each other between
the side bars F of the floor are arranged longitudinally and parallel with the floor two
or more iron or other suitably shaped bars G which are guided and supported near
their ends on rollers H mounted in bearings I within the walls of the building;
Against the upper webs or sides of the bars G are attached flat or other shaped upright
tappet and supporting arms J which correspond in number and distance apart along
the bars G with the number and width respectively of the sections A of the floor and
are of such height that the free or unhinged side of each section A when the floor is
horizontal as shown in figures 1, 2, 3 and 6 rests upon a straight flattened portion of
the top edges of its corresponding tappet and supporting arms J, the said edges of
which curve rearwards and downwards from these flat portions towards the bars G.
Across the framework of each section A where it rests upon the arms J are fixed
bearing and rubbing strips K which incline inward towards the hinged side and
perforated covering C of the section A.
On the underside of each bar G is formed or attached a toothed rack L (seen more
particularly in figures 7 and 8) into which gears a toothed pinion M keyed on a
shaft N which is arranged beneath the bars G transversely to the floor and mounted
in bearings within the walls of the building. At one end of the shaft N is fixed a
spur-wheel P which is geared into by a pinion Qoperated by hand.
Assuming that the dumping floor is in its normal position or with the perforated
coverings of its various sections A presenting a continuous horizontal upper surface
as seen in figures 1, 2, 3 and and that the free or unhinged side of each section A
rests upon its corresponding supporting arms J, when it is required to dump the
floor the pinion Q and spur wheel P are rotated, whereby the toothed pinions M are
also rotated and cause the toothed racks L, with the bars G and their tappet and
supporting arms J to slide longitudinally on the rollers H towards one end of the floor
and in so doing the sections A fall radially on their hinges D until in the position
seen in figures 3 and 4 when the malt is dumped therefrom onto the floor below.
To raise the sections A again to their horizontal position the pinion Q, spur-wheel P
and pinions M are rotated in the opposite direction, which causes the bars G with the
tappet and supporting arms J to return to their original position, and in so doing.
the curved edges of the arms J striking and bearing against the rubbing strips K. on
the bottoms of the sections A will thereby gradually raise the latter into the horizontal.
plane.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :-
1. In a malt kiln dumping floor, the combination of the sections A hinged at either
corner of their respective ends and having bearing strips K with upright arms J,
bars G and rollers H, substantially as shown and for the purpose described.
2. In a malt kiln dumping floor, the combination of the sections A hinged at
either corner of their respective ends and having bearing strips K with upright arms J,
bars G having toothed racks L, rollers H, toothed pinions M Q, shaft N and spur
wheel P, substantially as shown and for the purpose described.
