The compara- Ihe dish washing machine of my design comt1vely slow rotation of the gear 35 causes the ecprises a casing I supported by four standards or centric 39 to impart oscillating motion to'the legs 2. A platform 3 is attached to said legs and yoke and its associated vertically disposed shaft 5.
4|. The shaft 4! is rotatably supported by the casing 32 and the cover 97 and is extended through a fluid tight bearing 42 in the partition 22 to protect the oscillating mechanism 9 and the motor 1 from water leakage in the casing I. The shaft 4| extends upward through the casing l and is journaled in a bearing 45 at the top thereof. The shaft 4| carries the arms 41 and 49, in spaced relation thereon.
Both arms 41 and 49 carry identical mechanisms for the purpose of oscillating the spray pipes l6 and 20 respectively, and a description of but one will be made. Each arm has an adjustable link universally attached thereto, said link 69 having its other end attached to the respective spray pipes.
Each of the spray pipes l6 and 20 consists of two separate tubes having spray nozzles 66 longitudinally spaced on one side thereof. The
The shaft 64 carries a sleeve 61' which has as an integral part thereof, a stub-shaft 69. The latter serves as a pivot for attachment of the other end of the link 69. The upper part of the stub-shaft 69 is threaded to receive a nut III for holding the link 60 in place. The oscillating movement of the shaft 4|, through the levers 41 and 46 and associated therewith links 50, is therefore imparted to the spray pipes l6 and 20.
The dishes or other articles to be washed are placed into the dish racks and the latter are moved into the casing l. The doors H are slid down and the motor I started. The latter drives the pump 9, which sends the fluid up the pipe l9 to the spray tubes l6 and 20. The oscillating mechanism rocks said spray tubes and the fluid forced from the nozzles 66 is thereby directed and spread over the dishes. fluid is such that it washes of! the dishes.
The pressure of the all the dirt and waste In dish washing machines of a larger size, I provide an automatic conveying means for the dish carriers, which is shown in detail in Figs. 8 to 11. It comprises a trackway 16 formed of angle bars 16 supported by brackets 11 which are afllxed to the walls of the casing I.
The brackets I1 also support a pair of bars 19 adapted to slide back and forth upon bracket extensions Ill. The bars 19 carry sets of dogs 9| adapted to engage tooth racks 92 attached to the bottom of the dish racks l6. The mechanism which I employ to actuate the bars 16 consists of a lever 64 which is an integral part or a lever 48 adapted to oscillate the spray pipe and is aflixed to the oscillating shaft 4|. The lever 94 carries a link 85, the other end of which is connected to the overload release mechanism 81. The latter consists of a hollow casing 90. having an open end 9|, on both sides of which half-circular grooves 92 are formed. A member 93, having cylindrical portions 94 resting in said grooves 92, is yieldingly urged against the casing by a spring 96, one end of which is afflxed to the member 93 and the other to the afiusting bolt 91. The casing 99 is affixed to a cross-bar 99 which. with a bar 99, keeps the bars 19 in spaced relation.
The reciprocating motion of the bars I9 operates the dogs 9| and moves the dish carriers IS in a direction to the discharge door of the casing.
When a dish rack jams to cause an overload on the motor, the member 93 of the overload release mechanism 91 swings about the cylindrical portions 94 as pivotal points, and the reciprocal motion of the bars 19, and consequently the advance of the dish carriers l6. ceases.
Having thus described this invention, what I claim and desire to secure by Letters Patent is:
In a dishwashing machine, a casing; parallel tracks arranged lengthwise of said casing for supporting dish racks thereon; guides beneath each of said tracks; a slide in each guide beneath each track, each slide being held in its respective guide by the overlying track; both sides being held together in fixed relation, being movable in unison on a fixed horizontal plane and in a longitudinal direction relative to the tracks; dogs pivotaily mounted on the sides of said slides at spaced points thruout the length thereof, said dogs being movable above and below the horizontal plane of the tracks to engage and disengage the dish racks on said tracks in accordance with the movement of the slides.
