Application led January 3,1905. `Serial No. 239,436.

` TocbZZ whom it may concern:

Myinvention relates to washing-machines.

In particular my improvements relate tov that typefof washing-machine in which pounders reciprocate in a clothes-receptacle.

The invention will first be fully described in detailand the features of novelty then set forth in the claims.

In the drawings, Figure 1 is a side elevation and artial section of my improved washingmac 'ne. Fig. 2 is a top plan view with the tub and legs omitted and the vertical Standards and rods in cross-section. Fig. 3 is a detailedview of the rod 20 and frame part 6,

serving as a mounting therefor.

Referring to the drawings, 1 is a horizontal base-frame supported by legs or standards,

`such as 2.

y 3 is a frame member extending across the machine below the tub and secured to the legs 2. 4 is another frame member secured to the legs or standards and extending at right angles to themember 3.

6 is a depending vertical portion `of the y framework.

7, 8, and 9 are vertical upward projections of the framework or standards.

10 is a supplemental horizontally-disposed frame rigidly secured to standard 7 at 11 and to standard 9 at 12 and having bearings 13 and 14, into which a shaft 15 is journaled.

16 is a wheel mounted on the shaft 15, preferably on the outer side of the horizontal frame 10.

17 is a link pivotally connected at one end to the outer portion of the wheel 16 at 18 and at the other end to one extremity 19 of a horizontally-disposed rod 20, which is pivoted at 21 to the depending vertical frame portion 6. Vertically-reciprocating rods 22 are pivotally secured at 23 to the ivoted rod 20. These rods 22 are preferab y slidably mounted in the horizontal frame portion 3 and the vertical standards 7 and 8 at 24 and 25.

- The rotation of the shaft 15 through the above-described link mechanism alternately Vraises and lowers the opposite ends of the pivoted rod 15 and in consequence reciprocates the vertical rods 22 in alternation. The

rods 22 are preferably angularly bent near 4frame portions 9 and 3.

their upperends, so as to form the horizontal ortions 26. Short vertical rods 27 areipreferably slidably Secured to the horizontal portions 26 by any suitable means, such as sleeves or bearings 28, and are held against vertical downward displacement by any suitable means, such as pins run through perforations 51.

The vertical rods 27 sup ort a pair of plungers or pounders 29, w ich are alternately lowered into a clothes-receptacle or tub '30 and raisedtherefrom by the reciprocation of the rods 22 and 27. The pounders are secured to the rods 27 by means of sleeves or casings 49, provided with set-screws or any other suitable means. Springs 36y normally bear downwardly on thesleeves 49.

The tub 30 is rigidly mounted on aratchetwheel`37, which is mounted rotatably on the framework and turns on a pin 1a. shaft 15 is rigidly mounted a cam 38, with a cam-strap 39 surrounding the same and disposed horizontally below the ratchet-wheel 37. The free end of the cam-Strap 39 is iv- On the otally connected to a short link 40, which atter -is rigidly secured to a short shaft 4,1. Shaft 41 is journaled in bearings in rigid projections 42 and 43, secured,

A second short link 44 is rigidly secured at one end to the shaft 41 and atthe other end is pivoted to a `pawl 45, engaging the ratchet-wheel 37.

Preferably a supplemental pawl 46 is rigidly mounted on the frame portion 3 to engage the ratchet-wheel 37 at nanother point.

The rotation of the shaft 15 through the rotation of the cam 38 fixed thereon and the consequent reciprocation of the cam-strap 39 oscillates the link 40. y This oscillatory movement is transmitted through the shaft 41 \to the link 44, whiclioperates the pawl 45, and thereby rotates the ratchet-wheel 37. The pawl 45 is preferably provided with a coilspring 47, secured at one end to the pawl 45 and at the other end to the frame portion 4. This'spring 47 normally bears downwardly on the pawl 45 which is prevented from falling below the ratchet-wheel by the rojection 48.

With every complete revo ution of the shaft 15 both pounders 29 are alternately depressed and lifted once and the clothes-receptacle 30 is rotated a small fraction of a revolution corresponding to the space between two consecutive ratchet-teeth. The shaft 15 may be rotated by hand or power.

Standard 9 is well adapted to support a respectively, to

clothes-wringer in case it is desired to use a wringer.

It is understood that I contemplate any changes in the above-described device which may come within the scope of the claims.-

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a washing-machine, thecombination of a clothes-receptacle, a pair of pounders, vertical reciprocable mountings for said pounders, springs interposed between said pounders and their respective mountings, a rock-arm centrally pivoted below the clothesreceptacle and connected near either end with one of said pounder-mountings, a rotary shaft, a crank thereon, a pitman connecting said crank with one end of said rock-arm for oscillating the same, a circular rack connected with said clothes-receptacle, a rock-shaft bearing a pawl engaging said rack, an eccentric on said rotary shaft, and a connection between said eccentric and said rock-shaft.

2. In a washing-machine,the combination of a tub, a rotary mounting therefor, a circular rack carried by the tub, and a pawl mechanism for moving the rack to rotate the tub, pounders Within the tub, vertical rods without the tub, one for each pounder, and each having a horizontal arm provided with a bracket through which passes a stem upon which the corresponding pounder is mounted, and a spring intermediate each pounder and its bracket, serving to normally retain Ythe
