Improvements in Dish Washing Machines.
We, JAMES STEPHEN STEVENS and CHARLES AUGUSTUS WOOD, of No. 27
The Arcade, City of Cleveland, State of Ohio, U.S.A., Manufacturers, 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:-
The invention relates to dish washing machines, and consists in the construction
hereinafter described and especially pointed out in the claims.
In the accompanying drawings
Fig. 1 is a perspective view of the machine, with the side of the tank mostly
broken away and the cover and operating mechanism removed.
Fig. 2 is a perspective view of the rack frame, and
Fig. 3 is a detail of one of the hinges of one of the pivoted racks.
Fig. 4 is a perspective view of the machine, with the cover partly raised.
Fig. 5 is a view of a corner section of the supporting frame.
Fig. 6 is an enlarged view of a section of the tank and the cover on a line
across one of the cover hinges.
Fig. 7 shows a strap fashioned as shown in Fig. 6 for a hinge, and
Fig. 8 is a cross section of the top of the tank away from the hinge.
A represents the main frame of the machine. This frame has angle iron legs, a,
and sheet metal sides and ends, a. bent at right angles along their upper edge
and forming a seat for the tank, B. The legs project above the edges of the sides
and ends, and the tank B rests between them. By making tank and legs separate
the tendency to creep over the floor when the machine is operated is avoided.
The tank B is of sheet metal with its bottom stamped into the form shown.
Along the top portion thereof is a deflector, b, stamped therein and of sufficient
width and depth to deflect the water that is whirled around by the paddles away
from the point of intersection between the cover and body so as to avoid leakage
at this point. The sides and ends extend slightly above the deflector, and the
cover C is formed with a skirting, c, which closely overlaps this vertical
extension on its inside down to the shoulder a' of the deflector so as to prevent
leakage from any back water that may be thrown to this point. The skirting e
extends entirely around the cover.
The cover, for greater convenience, is detachable, and for this purpose has a
hinge of elastic sheet metal, and a suitably curved bearing c² near its outer edge
and a straight edge, e³, outside of the bearing, and this end is free from the cover
so as to readily pass under the strengthening wire, c', in the upper edge of the
tank and locked thereon, as seen in Fig. 6.
The bottom of the tank is made from a single sheet of metal and with its
sides D inclined to the centre, where it has a transverse channel, d, deepening from
top to bottom, and draining into the cock D¹.
E represents the dish rack frame in its entirety. This frame is formed in one
rigid piece, except. the wings, and is bodily removable from the tank. Above it
and preferably hinged thereon, are side wings adapted to be swung inward when
access is desired to the space beneath the wing. Thus, tracing frame E, we find,
first, a lower part, e, which fits snugly in the corners at the bottom of the tank;
then the inclined portion e', and then a more inclined portion, e², at which point is
the cross pivot wire e supporting the pivoted rack e. From the cross wire the
frame makes a dip e, on either side to form the central dish rack portion over the
paddles. All the parts except the wings et are rigid and firm, and the frame thus
constructed is strong enough to support all the weight of dishes brought upon it.

page_text: No lugs, brackets, or other artificial means of support are required to hold this
frame, and hence there need be no boring of holes in the sides of the tank to
attach supports, though such may be used if desired.
The wings

may be pivoted on lugs on the sides if preferred instead of on the
By making the tank and the supporting frame separate from one another we
avoid the tendency in the frame to creep or travel over the floor, which is
unavoidable when the two are rigidly connected.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is—
1. In a dish washing machine, a rigid frame having legs extending above the
sides of the frame, in combination with a tank adapted to be held in position by
the said legs and removable from said frame, substantially as described.
2. In a dish washing machine, a supporting frame having legs at its corners
extending above the edge of the frame and sides lowest at the centre, in
combination with a tank having its bottom lowest at the centre and supported on
the sides of the frame between the leg extensions, substantially as described.
3. In a dish washing machine, a supporting frame, a separate removable body
resting on said frame and a detachable cover having a slip hinge by which it is
supported on the body and adapted to be easily removed and replaced, substan-
tially as described.
4. The tank having a deflector on its inside near its top and a shoulder above
said deflector, and a cover with a skirting or flange extending down to said
shoulder, substantially as described.
5. The dish-rack frame consisting in a base portion rigid throughout and
extending from end to end of the machine, and the top side racks pivoted to turn,
substantially as described.
6. The dish-rack frame having a rigid base portion resting on the bottom of the
tank at its ends and extending over the paddle wheel at its centre, and pivoted
wings above said frame, substantially as described.
7. The tank having its bottom deepest at the centre and a drain channel stamped
therein and deepening from top to bottom, substantially as described.
Dated this 5th day of October 1891.
