SPECIFICATION forming part of Letters Patent No. 536,254, dated March 26, 1895.

Application filed August 30,1892. Renewed August 10, 1894- serial No. 519,963. (No model.)

Toall whom it may concern:

vBe it known that I, ELISHA HENRY AL- VORD, a citizen of theUnited States, residing at Pialschie, in the county of King and State of Washington, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification, reference being had to the accompanying drawings, .wherein similar letters and numerals of reference in the different figures indicate corresponding parts.

My inventionrelates to machines for washing dishes, vegetables and other articles, in which jets or streams of suds or clear water are forced into baskets holding the articles to be washed, by means of swinging sprink-' ling-pipes operated by peculiar pumping and intervening mechanism; and it consists in the peculiar arrangement and construction of parts united to facilitate the washing or cleansing process, as well as in the combination of-parts constituting the pipe-mechanism and the pumping mechanism.

In the drawings Figure 1 is a side view of my machine, one side of thecase being removedalso showing a longitudinal sectional view of the cover. Fig. 2 is a cross sectional view of lug 17. Fig. 3 is a plan View of the upper portion of carrying-arm 14, and its connections. Fig. 4 is alongitudinal sectional view of'the swivel. Fig. 5 shows the perforations of a portion of my sprinklingpipes. Fig. 6 is a cross sectional view of my machine cut through on the broken lines a: w, of Fig. 1, exhibiting also pump-handle 36, and its connections as shown. Fig.,7 is an end view of the pump and its parts(end of case removed). Fig. 8 is across sectional View of guide-guard 90, out through on broken line 19 of Fig. 7. Fig. 9 isaplan viewof my machine and, its parts out through on broken line y y of Fig. la portion of the tiltingplate being removed-showing parts belowalso showing bottom of the wire-basket. Fig. 10 is a plan view of the pump end of my machine- covers 10 and 94 being removed exhibiting portions of the pump and its connections. Figs. 11, 12 and 13 are detail views presenting differentformsof the pump-handle. Fig." '14 is an end view "of amodified pump and case, and parts of the pump. Fig.

15 is a sectional view of the lower portion of the pump cutthrough on broken line it h of Fig. 9, and a central sectional view of the upper portion of the pump and its parts. I Fig. 16 is a cross sectional view of the lower portion of the pump, out through on broken line g g of Fig. 9, exhibiting the inlet-valves and rodconnections. Fig. 17 is a cross sectional view of lug 56 and. depressions 57 and 57, out through on broken line )5 tot Fig. 15. Fig, 18 is a cross sectional view of a portion of the valve-case, cut through on broken line 'i z' of Fig. 15. Figs. 19 and 20' show a modified form of my tilting-plate. Fig. 2i shows a modified form of the case and cover in which the hinge is placed-above and at one side of the cover. Figs. 22 and 23 show rod connected directly with log 37. Figs. 24 and 25 show the mannerin whichrod43 is connected when fastened permanently to the basket.

In the drawings, 1 is a wooden or metallic case for holding the wash-waters, shaped as shown in Figs. 1, 6 and 7, of'the drawings, having its bottom sloping toward one end. A depression at the lower end serves to catch and hold the water. Over this depression and drawing its water therefrom, is mounted the pump 5. The lower part of this case is divided longitudinally into two compartments E and F bya vertical partition 2. Above this partition and resting upon two stands 3 and 4 is the pump 5, with mechanism for operating the same. as shown in position by dotted linesinFig. 1) are used both to retain and to liberate the Water. I

The upperportionof case 1 is curved outward as shown at A and B or O and D, to receive the cover 10 in such manner as to prevent the escape of water. There are four brackets marked 8 fastened to the sides of the case-three of them showing in the drawin gs-uponwhich rests awire basket 9, within which may be placed dishes, vegetables or any articles to be washed.

10 is a cover for the said case, with ahandle 11. It may be hinged as shown inFig. 6, or

may be made otherwise removable as will be hereinafter described.

The case may be supported on legs attached thereto, or it may be permanently built in the kitchen as are sinks-either alone or in combination with a sink, see Fig. 1-95 being a portion of a sink in combination with the washing machine. When permanently built in, should there notbe room suificient for the cover to open, if hinged in the usual way, it may be removed by hand, or it maybe opened with hinge in position as shown in Fig. 21 of the drawingsin which instance the back of the case 1 extends upward, being bent and shaped as shown, and the back of cover is removed and the edge is shaped as shown in said Fig. 21. The hinges are then placed at or near the junction of the edge of the cover and upward extension, as at a of case 1.

12 is a bracket riveted to the bottom of the case, forming the pivot for the lever 14 and having a horizontally extending arm 13 at one end.

14 is a carrying or swinging arm pivoted to the bracket 12 by a bolt 15. The lateral extension of the upper end of this carrying arm has two lugs 16 and 17. (See Fig. 3.) Through lug 17 passes one end of a T 18 made with a lug 19 to hold lug 17 in place. Lug 17 has a side opening 20 shown in Fig. 2, which will not coincide with lug 19 in their regular movements, but will permit of their disengagement when turned so as to coincide. Cap 21 screws on the opposite end of the T 18, holding swivel-elbow 22 in place, as shown in cross section of the same in Fig. 4. From T 18 extends an arm 23, and guide-rod 24 connects arm 23 with the arm 13 attached to the bottom of the case. Through lug 16 passes a sprinkling-pipe 25, which is perforated on its under side as shown in Fig. 5. Pipes 25 and 26 are screwed to T 18, and an elbow 27 is fastened to the lower end of pipe 26, to which elbow is attached a sprinkling-pipe 28, similar to pipe 25 but perforated on its upper side.

29 and 30 are caps to close the ends respectively of pipes 25 and 28.

A flexible pipe 31 (either of rubber cloth or otherwise) conneetsswivelelbow 22 to the elbow-extension 32 ofpump 5. To the lower end of carrying-arm 14 is secured a lever with a projection 34. This projection and the lower end of lever 33 strike thebottom of case 1, and limit the swing of carrying-arm 14. Rod 35 connects lever 33 with pump-handle 36 by means of lug 37.

Now it will be seen that when lever 33 is raised by pump-handle 36, the upper end of carrying-arm 14 will be carried over toward the side A of case 1, and with it both sprinkling-pipes 25 and 28 (as shown by dotted lines in Fig. 6 of the drawings); and when lever 33 is being depressed, the upper end of arm 14 will be carried toward the side 13 of case 1, and also with it the said sprinkling-pipes. Guiderod 24 is of such length that pipe 28 will be carried from side to side simultaneously with pipe 25. The pipe 31, being flexible and connected with swivel-elbow 22, its upper end will readily pass from side to side. When water waste is placed in case 1 and the pump-handle 36 is raised, the pump fills and the discharging pipes swing to side A. When the said handle is being lowered, the water is forced up the flexible pipe 31 into pipe 25 and down pipe 26 into pipe 28 and discharges itself out of the sprinkling-pipes from above and below through the perforations and against the dishes or other articles in the wire-basket. Should any of the perforations in pipes 25 and 28 become clogged, remove caps 29 and 30 and force water through them. This action will clear such pipes. Rod 35 may be connected directly to lug 37 on pump-handle 36 as shown in Figs. 22 and 23 of the drawings, or it may be provided with a collar 38 and a coiled spring 3!) pressingagaiustlug 37 of pump-handle 36 and nut 40, as shown in Figs. 1 and 6 of the drawings. This coiled spring keeps the pump-handle against collar 38. Rod 35, collar 38, coiled spring 39, and lug 37 olpumphandle 36 are so adjusted that lever 33 will reach its highest point before pump'handle 36 is at its extreme height. Coiled spring 39 yields while pumphandle 36 is farther raised. Now pump-handle 36 must return to collar 38 before the sprinkling-pipe 28 begins to swing to side B. It is intended that this lowering of the pumphandle to collar 38 will be sufiicient to cause the pump 5 to fill sprinkling pipes 25 and 28 before the swinging motion begins, so that all the dishes in the basket will be sprayed alike. This basket 9 is made thus: The wires 41 are placed on the upper side of the cross-wires 42 which form the bottom of the basket. Plates and similar dishes are placed in the basket in the following manner: The first row leans against either side of the basket with the dishes lower edges resting upon wires 41, and between wires 42that is, wires 42 determine the space between the lower edges of each row of plates or dishes. The upper portions of each succeeding row of plates lean against the succeeding one. A stationary wire 43, as shown in Figs. 24 and 25, extending across the upper portion of the basket at any position between the sides of said basket, or a wire 43. shown in Figs. 1 and 6 of the drawings, shaped as shown being bent at each end, engages with a wire of the bottom of the basket forming a hinge so that this wire will swing upon the bottom of the basket only in the direction shown by dotted lines in Fig. 6-but when in position for holding plates, the lower part of each end rests against the bottom of the basket so as to resist the pressure of the plates. Cups and such dishes are placed on the bottom of the basket, their openings downward.

It is contemplated that each machine should have as many baskets as are required to hold all the dishes or other articles to be washed on each occasion.

44 are the handles of the basket.

45 and 46 are two short suction pipes extending down into the depression of case 1, one on each side of partition 2. At the upper semi end of these suction pipes are the inlet-valves 47 and 48.

In Fig. of the drawings 49 is the pumpcylinder, held between thebase 50 and cap 51 by two rods 52 and 53 screwed into the stands 3 and 4 which also hold the pump into position, as shown in the drawings. 7 54 is a plunger provided with packing-rings 55 and 55' or any other packing common to pumps. This plunger has lug 56, and the depressions 57 and 57' for receiving connecting rod 58 which is attached at the upper end to the handle 36.

59 is a hole through the side of the upper portion of the plunger; and 60 is a similar hole in cylinder 49 at such a distance from cap 51 that when plunger 54 is at its highest 1 position, the two holes 59 and 60 coincide, and

allow all water that passes by the plunger to find exit. The diaphragm 61 slopes toward hole 59 to facilitate the exit of water.

62 is the outlet-valve of the pump, with coiled spring 63 for holding the same closed. A round piece of plate-metal 64 is soldered to the sides of the plunger forming an air-chainber between it and the diaphragm 61. This metallic head is'placed' at such a distance from the lower end of the plunger that when such plunger is pressed to its lowest position, the said plate presses the outlet-valve 62,

opening it sufficiently to allow the passage of waterand at the same time, this head allows space for the partial opening of the inletvalves 47 and 48, thus permitting the exit of the, water from both pump and pipes.

For opening the inlet-valves the following mechanism is employed: As seen in Figs. 1, 7, 10 and 16 of the drawings, the lower ends of valves 47 and 48 terminate in slots 66 and 67 formed as shown in Fig. 15. To cap 51 is pivoted a rocker-arm 68, having arm 69 extending downward. One end of shifting-rod 70 is secured to arm 69. Its other'end passes through case 1 and terminates in a handle 71. Rod 70 is provided with two notches 72 and 73 which engage in a cross-piece or case-catch 74. Thus rod 70 may be held in position at either notch. Rod 70 also engages arm 75 as shown. The valve-controlling rods 76 and 77, bent as shown, connect the ends of rockerarm 68 with inlet-valves 47 and 48, the upper ends of these controlling rods havingshoulders 78 and 79, above which shoulders are coiled springs 80 and 81 pressing against the ends of rocker-arm 68. When the rockerarm is in the intermediate position shown in Fig. 7 of thedrawings, both of theinlet-valves 47 and 48 are free to be raised. If the shifting-rod be moved to the right so as to engage the notch 72 with the catch 74, then theinletvalve 47 is prevented fromopening, and the water is drawn through the inlet-valve 48. If the shifting rod be pushed still farther to the right the spring 80 will yield, and the controlling rod 77 will lift the inlet-valve 48 from its seat. If, at the same time, the plunger is at its lowest point, it will hold open the outlet-valve '62, and the wa'tercontained in the pipes and pump will escape into compartment F. By moving the shifting rod similarly in the opposite direction, the other inlet valve will be opened, and the water will escape to the opposite side of the partition, or compartment E. Thus "one pump may be made to use both washing and rinsing water.

82 is a flat tilting-plate poised (as shown) on partition 2. To it is riveted an arm 83 connected with arm 85 by rod 84. Arms 75 and 85 move in the same direction-both being in fact parts of one and the same rod bent upward at each end and hinged at 86, 87, as shown. Above tilting-plate 82 and fastened to case 1 are guards 88, extending along that portion of case 1 abreast of tiltingplate 82 and across the end farthest away from the pump. These guards cause all water coming near and upon the sides and end coextensive with their width to fall on the said tilting-plate. Now, when shiftingrod 70 is pressed toward side A, the pump will use water from compartment E, and will tilt plate 82 so that all water will return into compartment E; and when rod 70 is pressed in the opposite direction, the opposite result is obtained. This tilting-plate82 maybe so constructed that that part of it nearest the carrying-arm 14 will slide toward the end of case 1 farthest away fronrthe pump and under the remaining part of the said tiltingplate-as shown in Figs. 19 and 20 of the drawings in which 82 is the tilting-plate having a sliding part96, 97 being the handle to said sliding part or plate-thus uncovering a portion of both washing and rinsing water, permitting one to use the washer as a sink or dish-pan for dishes or articles not convenient to wash in the machine. 89 is a thin piece of perforated sheet-metal or wire to strain the water as it passes to the pump.

90 and 90 are guide-guards to keep plugs 6 and 7 in place when rods 91 and 91 are raised and lowered. These rods have ban-- dies 92 and 92', as shown. A metallic piece may be fastened to the sides of case 1 extending from'one side to the other in position as shown by dotted line 93 in Fig. 1, to prevent water from falling into the uncovered portions of compartments E and F.

94 is a cover for that portion of the machine V not covered by cover 10.

will return-into side E. Now, place rod 70 so that notch 72 engages catch 74, thus making the pump use water from side F; work pumphandle 36 two or three strokes, and the dishes, &c., are rinsed. Disengage rod 70, and press farther toward side B. This action returns all rinsing Water from pump and pipes into the side F. Remove basket thus rinsed and place in the case another basket for cleansing, and proceed as before, and so on.

A rectangular tray with handle at each end may be used to place the wire basket upon while filling the said basket with dishes, &c., and carrying the same to and fro to catch any particles dropping from the dishes, due.

The pump-handle 36 may be in one part, or for convenience it may be made in two parts as shown in Figs. 11, 12 and 13 of the vdrawings. Fig. 11 shows when the handle-portion 36 contains a receptacle within which passes the free end of pump-handle 36. Figs. 12 and 13 show another means of connection, in which handle-end 36" consists of two jaws with a receptacle at one end and a bolt a at the other which engages handle 36, as shown.

Fig. 14 of the drawings is a modification of my machine, in which partition 2, tilting-plate 82 and guards S are removed from case 1, and case 1 holds but one kind of water. Pump 5 of the said Fig. 14. has but one inlet-valve 47'--and rod 76 is fashioned and bent as shown so that bylifting handle 92" of said rod 76', the valve 47' is raised. The outlet-valve of pump 5 is constructed like that exhibited in pump 5. In this modification, one plug or faucet is used. To wash dishes, &c.employing my modificationput suds into case 1 and place in a basket of dishes or other things; operate the pump-handle until cleansed; remove the basket and put in another basket, and wash, and so on until all are washed. Draw ofi water from case 1 and from pump 5 and pipes by lowering pump-haudle to its lowest point, and raise rod 76'-then put rinsing water into the case, and rinse each basket in turn.
