A New or Improved Interchangeable Dish and Bottle Washing
Machine.
FRANK CHARLES SHERMAN, of Number 5, North Saginaw Street, of the Town
of Pontiac, Oakland County, State of Michigan, United States of America, Life
Insurance Solicitor, 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:—
In dish-washing machines in which a stream or streams of hot water is em-
ployed to cleanse the dishes, it is important that the water be kept quite hot, and,
to this end, that unnecessary radiation be prevented. To accomplish this, and
for the sake of simplicity of construction, the cylinder of the pump employed
to produce the stream, has heretofore been placed within the chamber designed
to receive the dishes. This arrangement, as heretofore practiced, while serving
its purpose, is found to interfere with the placing of the dishes to be washed,
to the best advantage, and to materially diminish the capacity of the dish-
chamber.
My invention relates to and its object is to provide means for overcoming the
objection here indicated to provide a dish-washing machine in which approxi-
mately the maximum of capacity of the dish-chamber may be obtained with the
minimum of size and weight of the machine, and in which the pump-cylinder
and its discharge-pipe may be located within the chamber of the machine with-
out interfering with the arrangement of the dishes to be washed. The further
object of my invention is to provide means whereby my machine may be utilized
for washing bottles and the like.
I attain these objects by means of the devices, mechanism and arrangement of
parts hereinafter described, and shown and illustrated in the accompanying draw-
ings, made part hereof, in which-
Figure 1, is a vertical, sectional elevation of my device, taken on linear, Fig. 2;
Fig. 2, a top, plan view with portions of the lid broken away; Fig. 3, a vertical,
sectional elevation taken on line y y Fig. 2, and Fig. 4, a side view, partly in
section, showing my device adapted as a bottle washer.
Like numerals of reference indicate like parts throughout the drawings.
In the drawings, 1 is a rectangular vessel of sheet-metal supported on legs 2,
and having a closely fitting rectangular lid 3, One of the vertical sides of the
vessel is curved outwardly, as at 4, forming, approximately, a semi-cylindrical
recess off the chamber of the machine. The bottom of the vessel is provided with
a depression 5 coinciding with the bottom of the recess 4. This
depression gradually tapers away from the bottom of recess 4, or, if preferred, the
whole bottom of the vessel may be inclined uniformly. Within the vertical semi-
cylindrical chamber 4 is vertically disposed a pump-cylinder 6 which is removably
secured in position by means of cleats 7 engaging buttons or hooks 8 upon the
inner wall of the vessel. The bottom of the pump-cylinder projects below the
general level of the bottom of the vessel into the sunken portion formed by the
meeting of the recess 4 and the depression 5. In the pump-cylinder is a plunger 9,

page_text: (indicated by dotted lines in Fig. 1,) having a pump-rod 10, engaging a horizontal
handle 11 pivoted upon an upright bracket 12 rivetted to a wall of the machine.
In the bottom of the pump-cylinder is a lift-valve 13.
▸
From the interior of the pump-cylinder just above the valve leads vertical
pipe 14 to a point above the level of the top of the lid. The diameters of the
pump-cylinder 6 and of the vertical tube 14 permit the two to be placed side by
side within the semi-cylindrical diameter 4, so that they do not protrude into the
rectangular chamber of the vessel. From the top of the tube 14 leads tube 14",
extending above the top of the lid to a point just above the center of the lid, thence
downwardly through the lid into the chamber of the machine. The connection
between the tubes 14 and 14ª is an elbow 14b, loose upon the two sections of pipe
to which it is connected. At the other extremity of the tube 14 is another
elbow 14, forming a slip joint so that the mouth of the tube may be turned either
downwardly or upwardly as indicated in Fig. 3. It will be seen that by this
arrangement of elbows and slip-joints the horizontal portion 14 may be dis-
engaged and may be swung horizontally and that the vertical portion at the
extremity of the horizontal pipe 14ª may be disengaged or may be swung as
desired in a vertical plane.
Secured to the under side of the lid is a wheel 15 having its vertical shaft 16
arranged axially of the mouth of the discharge pipe. This shaft is journaled and
stepped at bottom in a stout wire frame 17 secured to the bottom of the lid, and
at top in a wire loop or cross-piece 18 in the discharge pipe. The wheel 15 is
made up of a series of radial curved blades or vanes, somewhat after the fashion.
of a propellor, as fully appears from Figs. 2 and 3. Disposed horizontally on
the bottom of the dish-chamber of the machine is a wire rack R, designed to sup-
port the dishes and to admit of their rapid drainage.
The operation of my device, thus far described, is as follows; Assuming that
the parts are assembled as above described and as illustrated in the drawings,
the lid is removed, the interior of the vessel is filled with soiled dishes to be
washed, a proper amount of boiling or very hot water is poured into the vessel, the
rectangular lid is placed in position, the elbow 14 and 14° are slipped vertically
into place and the pump handle is now operated. Water is now drawn into the
pump cylinder through the valve 13 and is forced out through pipes 14 and 14ª
downwardly onto the curved blades of the wheel 15. The force of the stream
causes this wheel to revolve rapidly and to throw the water violently in every
direction, by means of which the dishes are cleansed. The dish water is now
drawn off through plug 19 near the bottom of the pump, the dishes are allowed
to drain a short time, hot rinsing water is supplied to the machine, the pumping
is repeated and the dishes are now thoroughly cleansed and the operation is
complete.
20 is a tube which is adapted, at one end, to slip upon and fit the discharge end
of the elbow 14°, and is at its other end, contracted and perforated. Between
the large end of this tube and the perforations are projecting fingers 21.
Now
if the lid 3 be removed, the elbow 14 turned with its mouth upwardly, the large
end of the pipe 20 slipped over the perforated extremity of the tube 20 and
allowed to rest upon the fingers 21, several strong, minute streams of water will
be discharged into the bottle B, thoroughly cleansing the same, the water escaping
from the mouth of the 'bottle and dripping into the open chamber below.

Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed I declare that what
I claim is
1. A vessel, an outwardly curved portion in the vertical wall of said vessel
forming a recess off the chamber of said vessel, a depressed portion in the floor
of said chamber leading to the bottom of said recess, a pump in said recess con-
nected with the bottom of said recess, a discharge pipe leading from said pump
to the top of the chamber of said vessel, a slip-joint elbow at the top of said pipe,

page_text: a horizontal pipe leading from said slip-joint elbow, another slip-joint elbow at
the opposite end of said horizontal pipe whereby said horizontal portion of said
pipe may be swung in a horizontal plane, and whereby the discharge extremity
of said pipe may be swung in a vertical plane, substantially as and for the pur-
pose specified.
2. In an interchangeable dish and bottle washing machine, a vessel forming the
chamber of the machine, a pump adapted and arranged to take water from the
bottom of the chamber of said machine, a discharge pipe for said pump leading
to the top of said chamber, a slip elbow at the discharge end of said pipe, said
slip-elbow having its discharge end adapted to swing vertically, and a spraying
device connected with said slip elbow, substantially as and for the purpose specified.
3. In an interchangeable dish and bottle washing machine, a vessel, a pump
