To all whom it mag/concern:

Be it knownthat l, CHARLES E. Fosrnn,

"a citizen of the United States, residingin Bufialo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Convertible Sink and Washing Devices; and I do hereby declaize the following to be a full, clear, and

i an

exact description of the same, such as will enable others skilled in the art to which it appertains to make anduse the same, reference being bad to the accompanying drawings, and to figures of reference marked thereon, which forms part of this specification.

Like figures of reference refer to like parts.

This invention relates to convertible sink and washing devices. One of the objects of this invention is to partially modify the construction of a slop sink, of ordinary construction, and so adapt the same for the releasable attachments of a water circulating apparatus, including a pump, for washing dishes, vegetables and other articles, automatically, by means of power, and also do add these features to a. sink, without depreciating the uses of the receptacle as a sink, upon the removal of the said apparatus.

Another object of this invention is to pro- T vide a pumping apparatus, having no valves, which shall be simple in construc tion. V

Another object is to provide a special draining apparatus to the sink that will en-.

able the operator to either retain watermr washing fluidat difierent heights within-the; sink, during a continued inflow of fluid into the sink, or to hold thewater therein, when. filled with a given quantity, or to allow it all to drain 0%. i l A- further object is to provide a portable board to the sinlntha t shall be so constructed as to be used as' a cover to the same to be clamped on, when the sink has been converted for automatic washing-purin the sink to be automatically washed,

V A still further object is to provide means for holding articles in certain fixed positions wi the nth while water or washing.

below the sink bottom.

fluid is automatically circulated therebetween.

With these and other objects in view, my

invention consists in certain construction, one embodiment ofwhlch is illustrated in the drawings, is hereinafter described, its

operation is explained and what I claim is i set forth. 1

In the drawings,

Figure 1 illustrates, in perspective, a slop 6 sink, with drain board, having the sink modified for the reception of my automatic washing attachments, showing the sink ready for ordinary washing purposes.

Figure 6 is a fragmentary view of the pump casing adapted to set into the wen Figure 7 isa perspective View of a form of wire basket used to hold dishes in radial position about sink,

in the sink. In the figurea referring particularly to is a drain board 10, having spring grips 11,

at one end and clamps 12, at the other end 1 thereof. Behind the wall 7 are hot and cold water pipes 13 and 1d, connecting with a three way valve 15 of ordinary construction, from which leads the pipe 16 terminating in the downwardly bent nozzle 17. Jour- 1 naled upon the lug 18 is a bail 19, which is fixed tosheet metal splasher 20, shown thrown up out of service in Figure 1, and down for service in Figure 2.;

In thebom' 21 of the 1 is shown 1 0 the spiral pump within the t Figure 8 is a perspective VlEWgOf the. drain levers for adjusting the drain tubes in fixing the'level of the washing fluid with- Figure 1, there is shown a sink 1, standing 5 j upon legs 2, 3, 4 and 5, upon a floor 6 against a central drain hole covered by a perforate2d 3 gasket. Between the wall 7 and the sink 1 is the draining apparatus 24, having a tubular casing 25, terminating in a valve body 26, from which leads a drain pipe 27 passing down through the floor 6 to the sewer.

An inclined portion of drain pipe 27 connects the well casing 23 with the valve body 26. An overflow pipe 28 connects the grating 29 with the tubular casing 25.

The details of construction of the draining apparatus are shown in enlarged views in Figures 2 and 8. The tubular casing 25 is covered by a cap '30, upon which are fixed the posts 31. A U-lever 32 is pivoted at 33, to the outside of the respective posts 31, and is shown in Figure 8 to be resting upon the cap 30. Integral with the U-lever 32, and angularly positioned thereon, are the arms 34, to the outer ends of which are pivoted the lifting rods 35, respectively. To the inside of the top of the posts 31, is pivoted the U-lever 36, having arms 37, positioned at an angle on the body of the U-lever 36. Connecting the outer ends of the arms 37, is the cross rod 38 to which is journaled the lift ing rod 39. Positioned across the legs of the U-lever' 36 is the stop .rod 40, resting against 1 the lifting rod 39. A thumb piece 41 is provided with the U-lever 36 for easy manipulation.

'The lifting rods 35, and 39 passdown through the cap into the tubular casing 25 and connect with the respective auxiliary tube 42 and plug pipe 43, the rod 39 connecting with the pipe 43. v The lower end of the pipe 43 is fitted with a double conical plug 44, the lower part of which fits the seat of the valve body 26, when allowed to rest thereon, to cut off direct communication pipe 27 and the valve body 26.

Referring to the umping devices and the power connection tlierewith, there is shown a bearing 45, having a gland 46 with a packing 47, fixed within the bottom of the well casing 23. A shaft 48 is journaled in the bearing 45 and is directly connected with a motor within the motor casing 49. The shaft 48 terminated above in'a fiat'central portion 50, adapted to engage a slot in another shaft 51, which serves as an extension to the shaft 48, having fixed to it a tube 52, in sliding en agement with the shaft 48.

etween the tube 52 and the part 53 of the bearing 45, isositioned a ball thrust bear- 'mg 54. Fixe to the shaft 51 and to the tube 52 are the double spiral blades 55 and 56, which are incased within the cylinder 57,

open at the bottom and terminating in a" cap 58, fixed thereto, through which passes a threaded portion of the shaft 51 engaged tive portions of the spiral blades, 55 and 56.

Surrounding and fixed to the lower part of the cylinder 57 are the double spiral blades 60 and 61, adapted to revolve within the pump shell 62, which is spaced from the sink bottom 21 and the side walls of the well casing 23 by means of the angular fins 63, fixed to the shell 62. The upper part of the shell 62 is in the shape of a pan having radial fins 64, over which revolve the fan blades 65, fixed to a ring 66, which in turn is fixed to the cylinder 57. The purpose of the fins inside and outside of the shell 62 is 'to stop the whirling currents in the passing liquid and thus facilitate the action of the spiral blades, in lifting the liquid, when the pump is revolved. In Figure 4 is shown a modified form of pump to be used for vegetable cleaning, having a hollow ended shaft .67, with a slot 68, adapted to fit the flat part 50 of the shaft 48, shown in Figure 2. The spiral blades 69 and 70 are fixed to the shaft 67, which is surmounted by a. set of blades 71, adapted to take the same position, as the blades 65, as shown in Figure 2, when one pump is substituted for theother.

Surrounding the cylinder 57, in Figure 2, is a wire basket having a bottom 72 and a cylindrical portion 73, positioned about the cylinder 57. Joining the mid-part of the cylindrical portion 73, with the outer edge of the bottom 72, are inclined and spurred wires 74, adapted to support cups, as 75, and between which plates, as 75*, are positioned radial to the pump.

In operating the form of my device shown get the best effect from the currents produced by the ump. Hot water is run in through the pipe 14 to immerse the dishes and is then shut off. -The water is next charged with soap or washing powder. The electric motor within the casing 49 is started, to revolve the pum and the washing fluid is lifted by the bla cs 55 and 56 on the inside of the cylindrical casing 57 as well as by the blades 60 and 61', on the outside of the ,cylindrical casing 57. The water on the inside of the casing 57 is forced up by the rapid rotation of the pum and finds exit through-the holes 59, in t e form of fine streams radiating from the casing 57. The water on the outside of thecasing 57, raised by the spiral blades 60 and 61 is forced up into the pan portion of the pump shell-62 Dishes are placed. inside the sink, and are positioned radially to meaning;

, where it is caught by the bladw t5, 'and'a scattered b fountain action takes place throwing the water upward. Washi li aid from the holes 59, and the fountain is 'orced through the dishes toward the outer wall of the sink 1, and finds its way down between the fins 63, into the bottom part of the casing 23,-

where it is a sin caught up and forced throu h the ishes. This action is continu for a time, and while the pump is running, the levers 32 and 36 are thrown back into the position shown in Figure 8, thereby raising the tubes 42 and t3, allowin the dishes to drain, the water running 0 through the pipe '27, the valve casing 26 and the pipe 2'2 to the sewer. While the drain is thus open, hot water is sprayed over the top of thecdishes-lrom. the nozzle 17 the splasher 20, The dishes are thus al owed to rinse for a short time, when the tubes 42 and 43 are lowered to shut oh the drain and latter the water is I he Sll

shut 0d, after the dishes have again become immersed and the pump is allowed to forcibly pass the writer through the dishes, otter which they are drained ed again and allowed to dry 0% before removal or they can be otherwise dried in theopen air,.ii they I are hot. In case there is no hot water suply, then the heater 23 can be resorted to. t can also be used in heating up the receptacle 2 to dry odthe dishes after they are rinsed. When it is desired to hold the level of the water in the receptacle l to the loci. ht of the topof the tube 42, the tube 42 is e owed to rest upon the conical plug 44,

' "causing water-to seek the to of the tube 42 pl 27. 1 All ing dishes.

into whichit spills and rains into the ere it is dem red to wash vegetables, a dill'erent Mud er a basket can be substituted torthe one or vegetables a basket without the inclined wires it, having a tubular wire center to keep the vegetables from contact Y with the pump, will be suitable.

Before leaving the operation of the ump, Ill-wish to calliattentioni to the function of action of the water, which would otherwise take place within the well casing 23 and tend to destroy the lifting action 'of the spiral blades. -The radial fins 64, serve a similar purpose, in aiding the action of the fountain blades 65. v
