LOUIS J'UDELSON', OF NEW YORK, N. Y.'

WASHING MACHINE.

Application filed. November 2, 1922. Serial No. 598,557.

This invention relates to washing ma-t 10 chines. More particularly, it is directed to the type of washing machine having an interior rotary drum for overturning the wash in the cleansing process, and having a power wringer attached thereto. The object of the invention is to provide a washing machine of this character having a power driven clothes wringer attached thereto and adapted to be operated from the power mechanism for operating the rotary drum, provision being made for either operating the interior drum alone or simultaneously operating both the clothes wringer and the drum as desired.

A further object of the invention is to provide in a washing machine having a wringer attached thereto, a power meclia-.

nism of the character and for the purpose described which shall be easy to mani ulate and efiicient in operation to a high egree. 30 Other objects of this invention will ,in part be obvious and in part hereinafter pointed out..

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the following claims.

In the accompanying drawings, in which is shown one of various possible illustrative ber 21 formed in the.

embodiments of this invention,

Fig. 1 is a vertical elevation of a washing machine with wringer attached embodying this invention;

Fig. 2 is a cross-sectional view taken along line 2-2 of Fig. 1 and showing the power transmission mechanism for operating the wringer and interior -rotary drum;

Fig. 3 is a fragmentary view showing the mechanism for transmitting pow'er to the wringer. rolls and for reversing the direction thereof;

Fig. 4 in a detailed view out along line 4.4 of Fig. 2 showing part of the means for connecting the wringer drive to the main I power shaft; and I Fig. 5 is a detailed view taken along line 5-5 of Fig. 1 showing the means for mak- I v ing swinging connection of the clothes wringer to the washing machine. I

Referring in detail to the drawin indicates the outer casing or drum 0% the washing machine Within which operates the usual rotary drum 11 mounted on a shaft 12. 13 indicates the main shaft connected to the prime mover by means of the pulley 14 and belt 15 or connected to the power source in any other suitable manner. The

rotary drum 11 is operated from the main shaft 13 by a train of gears 16, 17, 18 suitably arranged and of'suitable construction for transmitting the desired motion to the drum. The particular manner of operatively connecting the shaft 12 to the power shaft 13 forms no part of this invention, and any suitable transmission mechanism may be employed for this purpose. Secured at one end of the casing 10, preferably at the end remote from the power end, is a clothes wringer which is indicated generally at 19, andextending longitudinally of the casing 10 is a shaft 20 suitably journaled in bearings 21, 22 adjacent either end of'the drum for transmitting the motion from the main shaft to the power drive of the clothes wringerf This shaft 90 is adapted to be driven from the main shaft by means of a worm 23 driven from a counterrshaft 24 in horizontal alignment with the main shaft 13, and which worm is adapted to operate the gear 25 mounted on the power end of the shaft 20. The worm 23 and gear 25 are housed in a suitable gear box 26 into which extends the shaft 20 through the bearing'memear box. The shaft 24 is journaled as at 2 in the gear box 26 and extends beyond the latter so as to leave a space 28 between the main shaft and itself.

Mlbunted back of the gear box 26 is a coupling collar 29 having an annular recess 30 formed therein to receive a block member 31. This collar is further provided with a key-way 32 adapted to receive a pin or key 33 extending from the main shaft 13. The shaft 24 has a key-way 34 out therein. adjacent the end projecting from the gear casing for a key .35 which affords positive engagement between the collar 29 and the shaft 24, as will be readily understood.

relative to the washing machine.

The collar 29 is adapted to slide on shafts 13 and 24, so that when said collar is moved into position so as to dispose the key-way 32 opposite the pin 33, the latter engages in said key-Way and shaft 13 is coupled to shaft 24 so that shaft 20 will then be driven in the manner already described from the On the other hand, when the main shaft. collar 29 is out of engagement with the pin sha t 13 is disconnected from shaft 24 and To facilitate the sliding of the collai 29,

I provide a shaft 36- adapted for longitudinal movement in a sleeve 37. The forward end of said shaft is provided with a head member 38 from which extends a pin 39, adapted to engage in an opening 40 in the block 31. Said head member rests against the sleeve 37 and is kept in engaging position with the block 31 by means of a coil spring 40 held between the rear end of the sleeve 37 and a collar 41 on the shaft 36. A hand lever 42 is provided for manipulating the shaft 36 so as to cause the pin 39 mounted eccentrically thereon to rock to and fro in order to slide the coupling collar 29 into and out of engagement with the key 33. N

For transmitting the power from shaft 20 to the power drive for the rollers 19 19 of the wringer, a spiral gear 43 is mounted onshaft 20 adapted to operate a spiral gear 44 mounted on the vertical shaft 45 which is the power shaft for the wringer rollers. From this shaft the motion is transmitted through gear 20 to either one of the gears 20 or 2O at right angles thereto, depending upon 9 the position of "the clutch 20 which is adapted to couple either one of said gears with the drive shaft 2O for operating the rollers. The particular drive mechanism for driving the wringer rollers may be of any suitable character. Preferably the mechanism such as described in my co-pendin application, Serial No. 555,947, filed April 12th, 1922, may be employed.

Means is provided for swinging the wringer 1n and out of operative position wringer itself is mounted on a support 46 adapted to swing in a bracket 47, by means of a sleeve member 49 loose on the shaft. 45 and connected to the support.46 at one end and extending through the bracket 47 at the other. Said sleeve member is recessed as at 50 for a bearing block 51 adapted to be urged against the sleeve by means of a screw member, 52 operated by a handle 53 (see Fig. 5). By operating the handle 53 the wringer may be maintained in operative or inoperative position by the frictional engagementof the block 51 against the sleeve 33 %the position shown in Fig. 2) then the,

The Z 49. When it is desired to swing the wringer from one position to the other, the handle 50 is operated so as to move the block 51 out of engagement with the sleeve 49, as will be readily understood.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment'above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be inter preted as illustrative and not in a limiting sense.
