Patented Apr. 8, 1930 PATENT OFFICE WILLIAM G. REID, or OAKLAND, o'ALIF'onNIA WASHING MACHINE I Ap lication filed April 11,

This invention relates to improvements in washing machinesof the reclprocatmg plunger type wherein lsembodied a motor drlven V mechanism adapted to agitate the clothes to be cleansed. I

' An object of my invention is to provide a novel washing machine having a plunger '7 adapted to move backwardly and forwardly with reciprocating motion inside an inclosure,

: whereby the clothes contained therein may be V subjected to acompressing and releasing action while washing 'fiuid' is forced therejthrough.

Another object of 'my'invention is to prol5 vide a washing machine wherein is embodied suitable mechanism for actuating a plunger .backwardly and forwardly within an enclosure, whereby the washing fluid contained therein is causedto move in a complete cycle in such. a manner that, successive charges of the fluid are forcibly circulated through the clothing to be cleansed. l

A still furtherobject of myinvention is to provide a washing machine having embodied therein novel .means for smoothly operating a plunger backwardly.and'forwardly with.

' reciprocating motion, whereby the water located in an enclosure may be so agitated as to thoroughly cleanse the objects located in l 3 the enclosure.

' Other objects more or less apparent will present themselves or will be specifically pointed out in the description to follow. In the accompanying drawings:

taken on the line 1928. Serial 110.26.),255.

Fig. 11 is a side view of a fragmentary part of the safetyiplatel mechanism showing the extreme position of the same in' dotted lines;

Fig; 12 is a sectional view taken on the line Referring to the drawings, the numeral designates a receptacle of any particular shape mounted on a frame 6 having suitable corner supporting posts 7 secured thereto.

Mounted in the receptacle 5 is a vertically disposed plunger Shaving its bottom and side edges positioned adjacent the. correspondingwalls of the receptacle so that the latter isdivided into two compartments 9 and 10. The plunger Sis so arranged as to move horizontally across the inside of'the receptacle, and is preferably secured to actuating guides 11 which movably extend through the rear side wall 12 of the receptacle and suitable bearings located in the'frame 6. The displacement of the plunger causes a variation in thesize of the compartments 9 and 10, and the latter, which is located at the forward end of the receptacle, is adapted to serve as the washing chamber for the clothes to be cleansed; f I

To permit'the movement of the liquid from compartment 9 into compartment 10 when the plunger is carried backwardlytoward in compartment 10. is forced upwardly through the clothes into compartment 9, and when the plunger is moved backwardly the door is opened to permit the liquid to flow through the opening 13 back into compartment 10. At the upper part of the plunger I have provided a plurality of vertical slots 15, through which the. liquid in compartment 10 may pass. The purpose of the slots is to allow some of the water in compartment 10 to pass into compartment 9, and at the same time prevent the clothes located in the former from passing over the top edge of the plunger when the plunger is moved to an extreme forward position.

V To prevent the passing ofliquid from com partment 10 into compartment 9 between the edges of the plunger and the sidewalls of the receptacle 5, I have secured shoes 16 to the plunger at pointsadjacent the side and bottom edges thereof. The shoes 16 are preferably constructed from a flexible material such as sheet copper, and are so positioned that they closely fit against the side and bottom walls ofthe receptacle, thereby sealing the space between the plunger and the said sides of the receptacle. The shoes upon moving with the plunger in a forward direction are firmly pressed against the sides of the receptacle 5 by the pressure of the compressed fluid against them, thereby preventing any clothes from jamming between the edges'of the plunger 8 receptacle.

Slidably positioned top of the. frame 6 is a top cover plate 18,

top of the receptacle. each secured at one of their ends to the frame 6 and at their opposite ends to the cover plate,

I serve to flexibly and normallymaintain the tacle.

said cover plate over the top of the recep- In the event the operator of the washing machine happens to have her arm inside the receptacle when the plunger is moved forwardly, she is not particularly in danger of injury, owing to the fact that the top cover plate 18 is adapted to move forwardly upon the distention of the springs 19.-

. A plurality of leaf springs 20 secured to i the for-ward wall of the receptacle serve to push the clothes backwardly after the plunger moves from an extreme forward position toward the rear wall 12.

Secured to the ends of the guides 11 is a triangular shaped member 21 which is securely clamped at its lower end to the end of a pipe 22 by bolts or other suitable means. The pipe 22 movably extends around a horizontally disposedguide rod 23 which is suitably secured to, the frame 6. v The opposite ends of the pipe 22 is pivotally attached to an end of an operating arm 24, while a crank arm 25 is pivotally attached to the opposite end of the said arm. The crank arm 25 is and the sides of the '2 inside supporting guide members 17 which are secured to the.

worm gear 31 which, through a gear 32, turns the rod 33 to operate a clothes wringer 34.

Located on top of the casing 27 is a semicircular projection 35 which, through pins, has a brake lining 36 secured to its inside surface. The crank 25 is provided with a downwardly extending projection 37 to which is .pivotally attached, as by a pin, a brake shoe 38. The brake shoe is movably attached to the projection 37 at its central part by a pin '39 having a spiral spring 40 located around the same, which spring normally maintains the brake shoe in firm contact with the brake lining 36. The brake shoe in resiliently contacting with the brake lining, places a load on the motor and causes the motor to smoothly operatethe plunger backwardly and forwardly without'any sudden or jerky motion.

A lever 41 pivotally attached on the frame 6 and suitably connected to the operating gears locatedinside the casing 27, serves as a means "for startingand stopping the operation of the-machine.

A horizontally extending guide rod 42 secured to the frame 6 and having the triangular member 21 slidably mounted thereon serves as a means for properly supporting the latter in an operating position. I

When the machine is to be 0 erated, suit-- able cleansing fluid is placed 1n the receptacle 5'to approximately half fill the same. The gears 28 and 26 are commencedto operate by manipulatinglthe lever 41, thereby causing the plunger 8 to move backwardly and forwardly through its connection with the above-described operating mechanism. As the plunger moves forwardly the door 14 is closed and thefluid in compartment 10 is raised through and around the clothes while the latter are being raised and compressed.

When the plunger is about to complete its forward stroke, the. risingfluid passes through the slots 15 in the plunger and falls into compartment 9. 7 After theplunger completes its forward stroke and commences to move backwardly the leaf springs 20 push the compressed clothes backwardly, thereby separating them'so the fluid can again pass through them. As vthe plunger moves backwardly, the fluid in compartment 9 forces the door 14 open, thereby allowing the fluid to pass into compartment 10through the'open ing 13 in the plunger; i '1 It is apparent to those skilledin the art that my improved washing machinemay embody forms or constructions other'than that illustrated and described, so for this and other apparent reasons it is my desire to havethe appended claim define the limits my invention may assume.

Having described my invention, what I claim is:

In a washing machine, a receptacle adapted to, contain washing fluid and articles to be cleansed, a plunger located in the receptacle and adapted to move with reciprocating motion backward and forward, a motor-driven mechanism for actuating the plunger, and a braking mechanism for giving the motor a load at all times, whereby the plunger may be smoothly operated backward and forward.
