' 4 Claims. (01. 6818) I 1 This invention relates to' improvements in clotheswashing machines and'pertains particularly to a machineof'the .type wherein clothes are encased inamovingre'ceptacle, r v

The primaryobject ofthe present inventio is toprovideIa novel and eflicienttype of clothes washer which will wash through the reciprocation of the clothes through the water but will effectively protect the "clothes against pounding or other action which might tend to injure-the fabric. a 1

Another object' of the invention is to provide in a washing machine' having a reciprocating clothes receptaclea novel means for imparting rotary motion to the receptacle in addition to its reciprocatory motion.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the app nded claims.

In the drawing:

Figure 1 is a view partly in elevation and partly in vertical section of the machine embodying the present invention;

Figure 2 is a sectional view taken substantially upon the line 2-2 of Figure 1;

Figure 3 is a sectional view taken on the line 3--3 of Figure 1;

Figure 4 is a view in elevation of a fly wheel of the structure. 7

Referring now more particularly to the drawing wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 designates a receptacle for the clothes washing solution, the bottomof which is preferably semicylindrical as indicated at 2 in Figure 2. The top of the receptacle is closed by the cover 3 and access may be had to the interior for inserting and removing clothes, through I a door structure, such as is indicated by the nut meral 4, which is disposed above the water line of thereceptacle.

Within the receptacle the opposite end walls are provided with the spaced parallel guides 5 which form opposing channels 6.

Extending across the receptacle from one end downwardly extending end arms 8, which slidably position in the'chann'els 6.

Disposedben'eath the beam 7 and between the free endsof'the arms'8 is aperforatedreceptacle 9 which is lpr'eferably cylindrical in. formand which carries. trunnions '10. at its ends whichare pivotally connectedawith :the arms8. This re.-

ceptacle is provided withxa door '11- which. closes an opening in the-wall thereof through which clothes are put in and removed:

The central .part of the-cover 4 is provided with an openingl12 through'which there. extends upwardly the vertically reciprocablezrod 13 which 7 at. its lower end is securely; connected with the bar 7 and at itsupper end passes through an aperture 14 formedtin' a guiding cross head 15. Q 1

This-head 15'is supported above-the top of the receptacle by the standards :16 which are mounted on the receptacle top in the manner illustrated and which are provided with shaft bearing openings 17 for the purpose about to be described.

Mounted upon the cover 3 is'a pair of bearings each of which is indicated by the numeral 18, which are in alinement one with the other and I with the bearingapertures 17 in the standards 16. Each of these bearings 18 'coact with a bearing aperture 17 for the support of a shaft 19'which at its outer end carries a fly wheel 20. At the inner end of each shaft 19 there is mounted a gear 21 and these gears are connected by a wristpin 22 which is eccentrically disposed with respect thereto as shown in Figure 3.

Connected with the wrist-pin 22 is one end of a connecting rod 23 which has its other end pivotally connected with the rod 13, at the point 24. Mounted at opposite sides of the receptacle 1 and to one side of the standards 16, are the bearing units 25 between which is rotatably supported a drive shaft 26. This shaft carries two pinion gears 27 and upon one end has mounted the pulley wheel 28 by means of whicha driving belt or other power transmitting means may be connect- 7 ed with the shaft. The pinions 27 are in mesh with the gears 21 and it will thus be seen that when they are driven or rotated power will be transmitted to the gears 21 and thus cause reciprocation through the wrist-pin 22 and connecting rod 23, to the drum carrying shaft 13. The drum will thus be raised and lowered in the receptacle and the cleaning fluid therein will be caused to pass forcibly through the apertures of the drum. t

In order that the drum may be rotated at the same time that it is reciprocated, there are secured to one side wall of thereceptacle 1 upon same passes the finger.

the inner side, a pair of spring arm-s, each of which is indicated by the numeral 29. These arms are connected at one end and have their other or lower ends curving inwardly away from the wall so as to frictionally engage the wall of the drum as the latter is forced down past them.

It will thus be seen, upon reference to Figure 2, that when the drum is all the way down and then is moved upwardly the free ends of these spring fingers will cause slight rotation of the drum through their frictional contact with the wall of the same. a

It will thus be seen from the foregoing that a novel and eflicient machine is provided in which the most delicate material may be washed without damage as the only strain placed upon it is created by the water flowing through the apertures of the drum.

Having thus described the invention, what is claimed is:-

1. A washing machine comprising a receptacle,- a pair of guides upon the inner surfaces of opposite walls of the receptacle, a frame structure having a pair of vertical members each slidably engaging a guide, an apertured'drum rotatably mounted between the vertical members of the frame, a rod connected with the :frame and extending vertically'through the top of the receptacle, power means upon the top of the receptacle connected with said rod for reciprocating the latter, and a resilient finger mounted within the receptacle upon a wall of 'thesame and having afree end arranged to 'f rictionally engage the drum and impart rotary motion thereto as the 2. A washing machine comprising a receptacle having a top, a pair of guides within the receptacle and upon opposite walls thereof, a substantially U-shaped inverted frame within the receptacle having the side portions thereof slidably engaging said guides, a rod connected with said frame and passing upwardly through the top of said receptacle, an apertured drum rotatably mounted between the sides of said frame, a pair of shafts mounted in alinement upon the top of the receptacle, a gear mounted upon each of said shafts, said gears being in spaced relation and the 'ends of said shafts spaced apart, a wrist-pin eccentrically connecthig said gears, a connecting rod coupling said wrist-pin with said .lflI'St rod, balance wheels mounted upon said shafts, and means for driving said ears.

3. In a-Washing machine, a receptacle, a cylinder within the receptacle having a foraminous wall, a vertically movable frame in the receptacle, means supporting the cylinder at its ends in horizontal position in the frame for rotation, means for vertically reciprocating said frame and the cylinder therein, and means engaging the cylinder intermittently during its vertical movement in one directiononly for causing the same to rotate always in the same direction.

4., Ina washing machine, a receptacle, a structure movable vertically in the receptacle, a horizontally disposed cylinder having a foraminous wall and mounted for rotation in a horizontal plane on the structurdxmeans for effecting the vertical movement of the structure and the cylinder, and a resilient finger fixed within the receptacle and disposed to be passed by the cylinder when the latter is moving in one direction and engage. the cylinder when itv is moving in the opposite direction-to impartan intermittent rotary movement to the cylinder.
