ATTORNEY Patented Jan. 7, 1930 UNITED STATES PATENT OFFICE MERLIN M. JACKSON, 01? SAN JOSE, CALIFORNIA, ASSIGNOR TO FRED HAMANN AND GLEN I. LANG, BOTH OF SAN JOSE, CALIFORNIA WASHING MACHINE Application filed August 17, 1927. Serial No. 213,616.

It is the object of the invention to provide a simple, compact washing machine mountable upon a laundry tray and so constructed and arranged as to eliminate the necessity of enclosing the impeller operating bar.

It is another object of the invention to provide a clothes washing machine of the character indicated wherein the clothes impeller may be quickly and easily thrown into or out of engagement with the operating 7 mechanism.

It is still another object of the invention to provide a clothes washer of the character indicated that will be economical to manufacture, of few parts, quickly and easily as sembled, effectively lubricated without danger of leakage, light in weight, durable, and highly efficient in its practical application.

In the drawing Figure 1 is a plan view of a washing machine embodying my invention, part broken away.

Figure 2 is an enlarged section on 22 Figure 1.

Figure 3 is a section on 33 of Figure 2.

Figure 4 is a section on 44 of Figure, 1, enlarged and with part broken away.

Figure 5 is an enlarged plan view of a portion of the impeller operating bar and adjusting means therefor.

Fig. 6 is a section on line 66 of Fig. 2, and

Fig. 7 is a detail view of the means for clamping the device onto a laundry tray.

Referring now more particularly to the drawing, I show at 1 a plate of such a size as to lie firmly in a horizontal position on the upper edge of one section of a stationary laundry tray 2 and overlying the wall dividing the two sections, the rear wall, and a portion of one end wall. The plate preferably extends the full length of the division wall of the tray and is secured thereto as well as to the back and end wall, by means of any suitable clamps as indicated at 3. The portion of the plate overlying the division wall carries a clothes wringer indicated generally by the reference character 4, and has a chamber 5 formed therein intermediate its length partially enclosed by an upstandingrannular wall 6. In the side of this wall directed toward the tray 2 is formed a bulbous portion 7 having a slot 8 formed therein a distance above the level of thebottom of the chamber as shown. Theupper edge of the wall-6 is provided with an outwardly extending flange 9. The remaining portion of the plate overlies the rear portion of the tray, its forward edge extending over the center of the tray and raised a distance as at 10 slightly below the bottom edge of the opening or slot 8.

In the plate 1 and over the center of the tray 2 is formed an opening 11 fitted with a conical bearing member 12 on which is mounted a gear 13 enclosed in a case 14.

Passing through the member 12 and engaging the upper endof the conical portion 15 of gear 13 and to revolve therewith is an impeller rod 16 having a clothes impeller mounted upon its lower end as at 17. Engaging the gear 13 is a rack 18 having a slot 19 formed upon the backthereof. In the slot 19 and journaled in plate 1, is a cam20 provided with an operating handle 21. By means of this cam the rack 18' may be moved into or out of engagement with the gear 13 as desired.

Mounted onthe chamber 5 and in vertical axial alignment therewith is a housing 22.

This housing is of less diameter, than thechamber 5"as shown and is provided with an outwardly extending flange 23 at its lower end adapted to rest upon the flange 9 to which it is secured by bolts 24. A depending flange 25 is carried by flange 23 to engage the wall 6 and form a seat or shoulder as at 26 for a bottom plate 27 as shown, the plate 27 having a bearing 28 formed therein for a shaft- On the shaft 29 and in chamber 31, is mounted any suitable wringer operating mechanism indicated generally by the reference 37, the shaft 38 connecting the said mechanism with the wringer rolls, not shown.

On shaft 29 and in chamber 32 is a conical bearing member 39 engaging the bearing member 38 and rotating thereon as the shaft 29 rotates therein. A gear 40 is formed integral with member 39 and engages a worm gear 41. The gear 41 has a shaft 42 rcmov ably mounted therein, and an electric motor is mounted on the housing by means of a bracket 43, and a driving connection is inserted between the worm gear shaft 12 and the said motor as at 14. By means of this mechanism, the operation of the motor will revolve the shaft 29 and reciprocate the impeller as desired.

An important feature of this invention is the construction of the housing 22 and the assembling of the several parts therewith. The gear 40 and bearing member 39 may first be mounted on the shaft after which the shaft '1 is inserted through the bearing 34 and the mechanism 37, this being followed by the plate 27. lVhen the eccentric 35 and bar 36 are mounted on the shaft the bar .36 is passed through the slot 8 and the housing seated upon the wall 6 and secured in posithe shaft to the eccentric, so that all partsare thoroughly lubricated, yet there is no danger of oil escaping into the tray 2.

The bracket 43 performs two important functions, it supports the motor 45 and is mounted on the plate 1 in front of the bar 36, thereby protecting it and preventing the washing from becoming entangled with it.

The construction hereinbefore set forth also permits of the mounting of a cover plate 46 on the plate 1 by means of hingesas 47. This plate may be dropped down to cover the forward portion of the tray when desired, or may be raised to uncover the same. hen raised it effectually protects all of the rear of the plate 1 and the parts mounted thereon and effectually prevents clothing or articles being washed from coming in contact with them.

Still another important feature of the inventionis the position of the motor 45. Vhen the motor is mounted upon the plate 1 and between the housing 22 and the more remote edge of the plate its weight is utilized in steadying the machine and holding it in position and less reliance may be placed upon clamping devices.

In constructing the device as above set forth the plate 1 is so proportioned that the rear edge thereof is in alignment with the rear edge of the tray upon which it is placed as at 48. This insures the impeller always being in the correct position and spaced a certain definite distance from the back of the tray, regardless of the size of said tray.

It is to be understood, of course, that while I have herein shown and described but one specific embodiment of the invention, changes in form, construction, and method of assembly and operation may be made within the scope of the appended claims.

I claimf 1. In a washing machine, a plate formed to seat on the top of a laundry tray and provided with a depressed part forming a chamher having an upstanding annular wall, said wall having a slotted portion and a horizontal flange, a housing having a horizontal flangesecured to said first named flange and having a depending flange engaged within the annular wall of the chamber and a downwardly facing seat, a bottom plate engaged within said depending flange and against said seat, a partition in the housing above said plate, a shaft journaled in said bottom plate andpartition, a clothes impeller rotatably arried by the plate, means to actuate the impeller having a part extending through said slot of the slotted portion, means on the shaft and disposed in said chamber to operate said actuating means, and means connected to the shaft above the partition to actuate same.

2. In a washing machine, a plate'formed to seat on the top of a laundry tray and provided with a depressed part forming a chamber having an upstanding annular wall, said wall having a slotted portion, a housing secured to the wall and having a partition, a bottom plate for the housing, means to engage the bottom plate to hold same in place, a shaft journaled in said bottom plate and partition, a clothes impeller carried by the first named plate, means to actuate the shaft, and means to drive the impeller from the shaft having a part extending through said slot of the slotted portion and into the chamber,

MERLIN M. JACKSON.
