To all whom t may concern.'

Be it known that I, WALTER S. BENEDICT, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification.

This invention is an improvement in washing machines and has for itsl principal object to provide a washing machine of this character which is simple and efficient in operation and cheap to manufacture.

In the drawings Fig. 1 is a vertical section through the machine; Fig. 2 is a section at right angles to Fig; 1; Fig. 3 is a section on the line 3--3 of ig. 1 and Fig. 4 is a top plan view of the machine.

The machine consists of a metal base plate 1 in which is mounted a wooden cylinder 2 having a metal ring 3 around its upper edge. A cover 4 is hinged at 5to the ring 3 and is clamped down by an eccentric clamp 6. Lugs 7 act as stops for the cover'4 when it is raised.

A motor 8 having a worm 9 on the armature shaft 1() is attached to lugs 11 projecting downwardly from the base 1. The worm 9 meshes with a worm gear 12 on a shaft 13 which is journaled in projections 14 and 15 projecting downwardly from the base 1. @ne end of the shaft 13 is mounted. in a sleeve 16 which has the crank wheel 17 vmounted on the end thereof, said crank wheel 17 having a ball 18 which engages a socket 19 in a link 20. The lower end of the link 20 engages a ball 21 on an arm 22 which is pivoted at 23 to a lug 24 on the bottom plate 1.

The arm 22 passes through a bifurcation 25 in the lower end of a plunger 26 which works through a guide 27 and stuffing box 28 attached to the bottom of the base 1. A roller 29 mounted in the bifurcation 25 rides on the upper. face of the arm 22 and a pin 30 bears against the lower face of the arm 22 and prevents it from coming out of the bifurcation 25.

Mounted on the upper end of the plunger 26 is the casting 31 which consists of' an outer ring 32 having mesh work 33 within the circumference of the ring. Braces 34 strengthen the mesh 33. A metal tub 35 having perforations 36 therein is secured to a flange 37 on the ring 32.

A casting or head 38, similar to the casting 31, is attached to the lower end of a screw 39 which works through a boss 40 raar ori-ica f in the cover 4 and has a hand crank 41 on the upper end thereof.V A lock wheel 42 is mounted between the boss .40 and the crank 41 on the screw 39. This will enable the casting 38 to be raised to the desired height and lock there.

A clutch member 43 ,on the sleeve 16 clutches said sleeve to the worm wheel 12. This will cause the sleeve 16, and consequently the crank wheel 17 to rotate, thus by the link 20 moving the arm 22 and the plunger 26 and consequently the casting 31 up and down.

As the clothes are placed within the tub 35 and between the

castings

31 and 38 they are pressed together and the water squeezed out, cons uently thoroughly rubbing and cleaning tiem, the rubbing being due through the construction of the castin s 31 and 38, on the up and down stroke o the plunger 26.

Mounted on the other end of the shaft 13 is a beveled gear 45 which is always in mesh with

beveled gears

46 and 47 on a hollow shaft 48 which extends upwardly through a casing 49 mounted in a projection 50 of the base 1. The shaft 48 also extends through a casing 51 having a circular base 52 mounted on a projection 53 extending out from the ring 3. A beveled gear 54 is mounted on the upper end of the shaft 48 and meshes with the beveled gear 55 which operates the wringer 56. A rod 57 which is operated by an arm 58 pivoted at 59 to a lug 60 on the enlarged upper end 61 of the casing 51, extends ldownwardly through the hollow shaft 48l and has its lower end connected to a clutch 62 which clutches either the

gear

46 or 47 to the gear 45, thus providing means for running th wringer in either direction.

A spring pressed plunger 65 has one end connected to a lever 66 pivoted in an arm4 position.

Legs 70 which are connected to the base 1 and to the rings 3 support the machine.

In operation, when the shaft 16 is driven \from the motor an up and down movement Of the. .inner @11b containing the clothes is produced, which compresses or squeezes the clothes between the bottom of said tub and the head 38, which as stated can be adjusted -to accommodate different amounts of clothes. This squeezing action forces Water through the clothes and effects the washing operation. rll`he operation of the wringer will be evident from the above description, the clothes being fed from the tub to the wringer by opening the cover 4, which lifts the head 38 sothat the clothes are accessible.

I claim: v

1. In a washing m'achine, the combination i of an outer tub, an inner perforated tub therein having a plungerextending through the bottom of the outer tub, means connected to the plunger to raise and lower the inner tub, a cover on the outer tub, and a perforated head connected to and supported by the cover and extending into the inner tub,

miaeee said connection includingv` a screw adjustable through the cover. y

2. lln, a washing machine, the combination of an outer tub, an inner perforated tub therein having a plunger extending through the bottom of the outer tub, means connected to the plunger to raise and lower the inner tub, la cover on the outer tub, and a perforated head connected toand supported by the cover and extendinginto the inner tub, said connection including a screw adjustable through the cover, and a locking device `on the screw, engaging the coverto fasten the screw at adjustment. In testimon whereof, aix my signature in presence o two witnesses.
