WASHING-MACHINE.

Specification ofLetters Patent. Patented Feb. 1916.

Application filed January 31, 1914. Serial No. 815,819.

To aZZ whom it may concern:

Be it known that I, CHARLES S. JOHNSON, a citizen of the United States, residing at Marcy, in the county of Oneida and State of New York, have invented certain new and useful Improvements in lVashing-Ma ence characters refer to like parts throughout the specification.

The object of the invention is to provide a simple, efficient washing machine that will be of especial service in cleansing garments, fabrics and delicate goods, such as'doilies and laces, without tearing or injuring the same. The machine will be found of inestimable value to housewives, who do their own weekly washings. The machine may also be built on a larger scale for use in tures will be observed by referring to the drawings in which:

Figure 1 is a side elevation of themachine; Fig. 2 is a vertical section of themachine, showing parts in elevation; Fig. 3

is a fragmentary view in perspective of a lever employed; Fig. 4 is a plan view of a disk employed; Fig. 5 is an enlarged detail I view of a'cap employed; Fig. 6 isa plan view of the machine; Fig. 7 is an enlarged fragmentary view in perspective, showing the detachable engagement of the angle irons; Fig. 8 is an enlarged fragmentary sectional view, showing parts in elevation of the machine; Fig. 9 is a verical sectional view, showing parts in elevation, of a modified construction of the machine. I

Referring more particularly to the drawings, the washing machine embodies a cylindrical shaped metal tub -'1 having a flanged upper portion 2 adapted to form a shouldered seat for the reception of the edge of-the cover 3. The cover 3 has sea sleeve 5 disposed in the center of the said cover 3. The aperture 6 of the sleeve 5 alines with an aperture 7 in the said cover 3, whereby to permit the vertlcal movement enlarged and have circular therealong of the rod 8, which is threaded at one end 9 for the mounting of the nut 10, that holds the rod 8 from sliding inward because of the tension thereon of the conical spring 11. The opposite end of the rod 8 is secured to the center of the disk 12, provided with a flange portion 13, whereby to guide the disk 12 in its vertical movements hereinafter described. The disk 12 is also provided with concentric apertures, so to permit of the passage of water thereby. The conical spring 11 has one end secured to the disk 12 and the other end secured to the cover The said spring 11 is conical in shapeto permit of the compression of the spring 11 into a single horizontal plane, whereby the disk 12 may have a maximum vertical movement. The cover 3 is held rigidly in detachable assembled position by the angle irons '15 whichhave certain of their ends loosely mounted to the reduced portion'l6 of the cap 17. The said ends are H apertures adapted to be detachably mounted to said reduced portion 16 between the nut 18 screw threaded to the lower end 19 of the cap 17 and the shoulder 20 formed upon the said cap 17. v

The opposite ends 23 of the angle irons engage in-a detachable manner the slots formed in the upper'ends of the angle irons 21, that extend along the outer surface of the cylindrical tub 1 and below to form the standards or legs 22. The cap 17 is provided with a threaded orifice 24 and with winged members 25-25, whereby the said cap 17 maybe easily turned upon the threads 26 of the'sleeve 5. The vertical movement of the cap 17 will cause a similar movement of the adjacent ends of the angle irons 15,

irons 15 will move in the opposite direction to that in which the ends adjacent the cap 17 move, so that when assembling the cover 3, and the cap 17 are screwed down tight, the ends of the angle irons 15, adjacent the cap 17, will lie below the upper plane of the circumferential ring 4:, upon which the said angle irons 15 fulcrum, and thereby cause the ends 23 of the angle irons 15 to move upward to pinch or engage in a secure man- I v ner the slots 20 of the' angle-irons 21. The cured thereto a circumferential ring 4: and 4 a-ngledrons 15 are so bent at 27 that all lie from portion 27 to their outward ends 23 in the same common plane. The said ends 23 of the angle irons 15 are limited, furthermore, in their movement by the straps 28 whereby the opposite ends 23 of the angle secured to the top surface of the cover 3. There is also a vent or cook 29 in the cover 3. Below the disk 12, there is-disposed a vertical movable disk 30, having the con centric apertures 31 for the passage of the water. The disk has a central boss 32 and is secured to'the upper end of a rod 33, which extends down through an orifice in the bottom 34 of the tube 1, which orifice is made water tight by the employment of the stuliing box or gland 35 and the packing 36. The lower end of the rod 33 passes through the guide sleeve 37 formed upon the brace 38 that is secured at either end to any two of the legs 22, that are di agonally opposite. The rod 33 is actuated in a vertical manner, whereby to move the disk 30, by the hand lever 39 fulcrumed at 40 to the links 11-41, which are pivoted at 4:2 to the depending lug 43 of the brace 141 secured at either end to the legs 22, thus constituting a movable fulcrum. The hand lever 39 is bifurcated at 45 to form the forks 16 having holes 47 for the assembling r of a pivot 418, that passes through the rod 33.

T o operate the machine, the cover 3 is first removed by unscrewing the cap 17 a short distance in order to relieve the tension on: the angle irons 15, whereby the cover 3 may be turned, so as to permit the ends23 of the angle irons 15 to clear the slots 20*,

' whereupon the cover 3, together with theconnected parts, that is the disk 12, spring 11, etc., may be taken fro-m the tub 1,

which is then filled, preferably up to the line 50-50 illustrated in Fig. 2,. withwater in which there has been disposed a washing powder or some like cleansing substance. Thesoiled or dirtyclothes are placed. into the tub-1 upon the disk. 30. The cover. 3 is replaced and turned until the ends 23 of the angle irons 15 engage the slots20 of the angle irons 21, whereupon the cap 17 is screwed down tight to the cover 3 in order to cause the ends 23 of the angleiirons 15 to pinch the slots 20 of the angle irons 21, and thus hold the cover 3 in a secure-manner. A packing 51 is employed to make a water tight joint between the edge of the cover 3 and its seat formed by the flange 2. Thehand lever 39 is now worked back and forth to thereby cause the alternate elevation and depression of the disk 30. As the disk 30 rises, it pushes the clothes upward against the upper disk 12 which yields or recedes into the position indicated by the dotted lines in the Fig. 2. This yielding of the disk .12 allowsthe clothes to be ele- Copies vated above the water line, whereby the pressure of the disks 12 and 30 will cause a wringing of the clothesin the upper location. of the tub 1. The successive de-- scent of the disk 30, however, followed by the like movement of the clothes, which are urged downward by the disk 12 under the pressure of the springll, causes the water,

which is set in agitationv by the descent of the disk 30 to boil up through, the clothes and remove the dirt and grease therefrom in a thorough manner. This processof alternately soaking and wringingthe clothes is very effective in the cleansing of the same,

and a few strokesof the hand lever 39 is suflicient for the purpose. The cleanclothes may then be removed and replaced by the dirty or soiled ones. The dirt will settle to the bottom of the tub 1-,, wherethe same may be drawn off through the faucet 52.,

Bypermitting the disk '12 to. yield, the

pressure on the garments in. the tub -1. is a gradual pressure, whereby themost delicate fabrics can be washed without injury to the same. I

Fig. 9 illustrates a certain modificatio'm in that the parts, which are similar to those of the former construction arereversed.

This construction avoids the use of the stuffing boX or gland 35. The lever 60 is fulcrumed at 61 to the link 62 pivoted at 63 to the upward extension 61 of the angle iron 21. The rod 33 is pivoted at 65 to the lever 60.

Having thus described my invention, what i I claim as new and desire to secure by Let-% ters Patent. is:

In a washing machine, the combination of a tub having a detachable cover, a rod slidingly mounted in said cover, a disk mounted to the end of said rod, a :spiral spring. mountedon said rod between said disk and said cover, whereby to permit said disk to yield, a second disk having concen: trio apertures, a rod attached to said second disk, a gland in the baseof said tub for thevertical reciprocation of said second named rod, and a lever pivoted to links constituting a ;movable fulcrum =for actuating, said T. L. WILDER.

of this patent may be obtained for five cents each, by addressing the ;Commissioner of Patents,

Washington, D. C.
