DISH-WASHING MACHINE.

Specification of Letters Patent.

Application filed November 4, 1907. Serial No. 400,701.

To all whom it may concern:

Be it known thatI, OBLA'N S. LEE, a citizen of the United States, residing at You stown, in the county of Vigo and State of ndiana, have invented a neyv and useful Improvernent in Dish Washing Machines, of which the following is a specification.

My invention relates. to improvements in dish-washing machines in which streams of water from a pump operate in conjunction with revolving dish trays.

Figure I. is a side elevation. Fig. II. is a top view. Fig. III. is a vertical cut section on the line, a: a: lookin in direction of arrow, II. Fig: IV. is a vertical cut section on the line a 0 looking in the direction of arrow Fig. II. Fig. V. is a view of a horizontal cut section on the line b 5 looking in direction of arrow Fig. I. with the tube extended. Fig. VI. isa detail top view of gear.

The cylindrical tank 1. constitutes the body of the machine to which is secured the pump cylinder 2. The lower head 3 of the pum cylinder 2 may be integral with or secure to the cylinder in'any suitable manner.

' The upper head 4 of the c linder 2 fits over side of the tank 1. said tube is the to of the cylinder an is retained in position ymeans of bolts 55 Fi I. assmg through lugs 6666 into a wit cylinder heads. The upper cylin or head 4 has reared from two diametrically op osite points on its upper surface two upward y extending arms 7 and 8 Fig. III. which extend a predetermined distance above the top of the tank 1. so that the crank shaft 9. when mounted in the bearings 1112 at the extremities of said arms will be in alinement with the horizontal shaft 13. Fi II. To arm 8 is secured the ide 14 wit the eye 15 of said guide immeiately above-the center of the cylinder 2. The piston rod 16 passes through the eye 15 of the guide 14 through the stuffing box 17 and is secured to the piston 18 in any suitable manner. A pitman 19 is pivotally secured at its ends tothe piston rod 16 and the crank portion 10 of the crank shaft 9.

The tube 20 shown in Figs. I. II. and V is closed at its ends and is secured to the outrovided with which open s 22 and 23 connect the a series of perforations 21 Fig. into the tank 1. Pi

upper and-lower on s of the cylinder with the tu e 20. Said pipes are rovided with valves mit ofthe passage of water from the cylinder 2 into the tube 20 and prevent its return flow. Pipes 26 and 27 connect the up or and lower end of the c linder 2 with t e tank 1 and are provide with valves 28 and 29 which ermit of the passage of water from the tan k 1. into the cylinder 2 and prevent its return.

It is evident that the revolution of the crank shaft 9 will produce an oscillating movementof the piston 18 and a consequent movement of water from the tank 1. through the pi es 262722 and 23 and cylinder 2 into t e tube 20 through the perforations 21 back to the tank 1. In order to secure more uniformit of pressure on the water in the tubes an consequently more uniformity of flow through the perforations a tube 30 connects at its lower end to tube 20 and has its ends closed forming an air bulb.

It is desired that streams of water ma be brou ht in contact with the dishes from a ove and elow. To rovide for this a horizontal tube 31 Fig. 1K and V connects near the bottom of the tank 1. with the tube 20; said tube extends a suitable distance toward the center of the tank 1. It is provided with a series of perforations on its upper side and has its inner end closed. A horizontal tube 32 having its inner end closed is provided with a series of perforations on its under side and is hinged to the upper end of tube 20 so.

that it may be turned upwards and outward to (position shown in dot Fi V. To the free en of the tube 32 is secure an eye 33, which is designed to pass over the upper end of the pe endicular shaft 34 thereby retaining said sha t in position. In order that the eye ma 33 readiy pass over the upper end of sh t 34 said s a t is slightly beveled at its upper end and the socket 36 is sha ed like an inverted cone which will rovi e for sufficient lateral movement of SE8? 34. Means are provided to bring the dishes in contact with the streams of water. coming from the per-' forations. 7

The perpendicular shaft 34 Fig. III. and V.- having the horizontal arms 35-35-3535 secured thereto is rotatably mounted within the tank 1. by means of a socket 36 in the center of the bottom of the tank 1. which forms a bearing for the lower end of the shaft 34. The upper end be a ed later described. A dish tray 3 is supdjustabl mountported on the arms 3535-35 35 from the shaft 34. Said trays are constructed of wire and are circular with a diameter a little less than the diameter of the tank 1. so that the shaft 34 and trays 37 may be revolved without co in contact with the sides of the tank 1. e bottoms of the trays are convex, and are provided with openings at their centers ada ted to pass over the shaft 34 Fig. III, e ear 38 is slidably mounted on the up er on of shaft 34 by means of sutures 39. 'g. VI. in said gear interlocking with similar sutures on said shaft. The lower hub- 40 of the gear 38 is mounted in a circular o ening in the center of the lid 41 of the-tank and the upper hub 42 is similarly mounted in the bar 43 secured to the lid 41 Fi II. Said lid is hin ed to the tank '1. anIl when .it is o ned sai gear is retained in its osition on t e lid 41 but the sutures 39 of t e gear 38 and shaft 34 disenga e. Said filer sliding off of the beveled end 0 shaft 34.

a. horizontal shaft 13 is rotatably mounted in the bea s 4444 Fig. II. and is in alinement with crank shaft 9 with the screw 45'integral with said shaft 13 in engagement with the gear 38. Theerank shaft 9 terminates at its outer end in the crank 46. The inner end of shaft 9 is recessed forming a slot 47 III. ada ted to admit the flattened end 51 of the s 13 fo which serves to transmit motion romthe crank shaft 9 to the shaft 13 and also to pera joint mit of the free movement of the hinge 48 of the lid 41 when said slot assumes a vertical claim as new and desire to secure by Letters Patent is,

The combination in a dish-washing ma- 4o chine of a tank, a vertical shaft rotatably mounted within said tank, horizontal arms on said shaft, a circular dish tray su ported on said arms, a ump and erforate outlet tubes providing or a plura ty of streams of water from said pump to" said tray with means for operating said pump and revolving said vertical shaft in con unction, said means comprising a horizontal shaft 13 rotatably mounted on the cover of said tank, said 50 horizontal shaft, having a flattened end 51 for engaging a slot 47 in a crank shaft 9 whereby the revolution of said crank shaft transmit motion to said horizontal shaft and provide for the opening of said cover .55 when said slot occu ies a vertical position, a screw gear 45 onsai horizontal shaft engaging a gear 38 centrally mounted in said cover and, sutures in said gear for engaging sutures in the'upper end of a-vertical shaft 34 substantially as and for the purpose described.
