GEARING.

Specification ofLetters Patent. Patented Dec, 26, 1916;

Application filed March 11, 1915'. Serial No. 13,560.

ful Improvements in Gearing, of which the following is the specification.

This invention relates to washing machines and gearing therefor, and particularly to dolly construction and dolly operating mechanism for such machines.

It is an object of this invention to provide a dolly which acts upon the clothes from below instead of from above, whereby the action of the dolly will not be affected by the amount of clothes in the tub, and a very few clothes may be washed as perfectly as the ordinary full charge for the machine.

It is another object of this invention to provide a gearing mechanism for driving the dolly of a' washing machine in which said dolly will be given a continuous periodic rotary movement in addition to its oscillations, so that the clothes in the tub in addition to being swished back and forth will be also continuously periodically rotated, or revolved back and forth so as to assume different positions about the tub as they are being swished back and forth therein.

Further objects and advantages of the invention will appear as the description to follow proceeds.

In the drawings, Figure 1 is an elevationpartly in section of the washing machine constructed according to my invention. Fig. 2 is a sectional plan view of a portion thereof. Fig. 3 is a sectional plan view upon another plan of the operating mechanism for the dolly. Fig. 4 is a sectional elevation of a portion of said gearing.

In the drawings 1 refers to the frame or bench of 'a washing machine, preferably made up of metallic angle bars. 2 represents the tub mounted in said frame or bench. The tub 2 it is to be particularly noted is'of peculiar and novel form and includes a tapered bottom 3 and a dome 4 and lid 5. It is preferablycast in one piece save for the lid, and from aluminum. The

I bottom 6 of the tub is provided with a central aperture 7 which is closed by the cir cular plate 8, fastened "therein by means of bolts such as 9. Preferably cast integral with the plate 8 is the upstanding sleeve 10 having bearings .11 and 12 at its upper and lower ends in which is mounted the vertical dolly operating shaft 13 having upon its lower end a pinion'14 by which it is driven by mechanism and in a manner now-to be described. I

Secured to the top of the shaft 13, as for instance by the pin 15, is the sleeve 16 which.

overlaps the sleeve 10 and is snugly fitted thereabout on the integral collar 17 at the bottom of the sleeve 10 whereby wabbling of the sleeve 16 is prevented. The sleeve 16 is provided with a number (in this instance four) of blades 18 and adjacent its bottom is provided with outstanding pins or rests 19.

The dolly proper is of a novel form comprising an elongated central hub 20 having a central aperture 21 and slots 22 so as to be slidable up and down upon the sleeve 16 and to be engaged with the blades 18 thereof to prevent rotative displacement with respect thereto. 20 are the'arms 23 which are rounded on their upper surfaces, as shown at 24, and are provided at their outer ends with the washing blades 25 which project a considerable distance upwardly from the arms 23 and downwardly to the level of the bottom of the hub 20. Spanning the hub 20 and the blades 25 are the webs 26 which assist in the stirring action of the dolly' in an obvious manner.

In operation the dolly is placed upon the sleeve 16, and slides down thereon until the onion. 1

Projecting radially from the hub,

bottom of the collar 20 rests upon the pins 3 against the corrugated sides thereof, and

the webs 26 assisting in the stirring action. By this means the clothes are operated upon from. below and it is immaterial how full a charge is put into the machine, the operation upon the clothes being the same no matter whether few or 'many are being washed at one time. Moreover, the tapered bottom of the tub cooperates with the new form of dolly so as to cause the clothes at all times to come into operative engagement therewith.

' I will now describethe gearing for driv- 13 is interposed between the bearings 27 and the collar28, the bearings 27 being integral upstanding web 30 which is rounded at its outer end. The bracket 29 is preferably formed integrally with the plate 8 which [closes thebottom of the tub.

Secured to the frame 1 of the machine by lugs or ears, such as 31, is a depending housing 32 provided with a horizontal bearing 33' in alinement with the bearing 34, secured to the frame 1 by ears or lugs such as 35. Mounted in the bearings 33 and 34 is the with the bracket 29 which has thereoh the driving shaft 36 provided at its end with.

the driving belt wheel 37. Keyed to the shaft 36 adjacent its inner end is the beveledpinion 38 having projecting therefrom the clutch tooth 39. Pinned to the end of the shaft is the clutch element 40 having a tooth 41 for engagement with the clutch tooth 39. The shaft 36 is provided with a collar 42 in engagement with which is a fork 43 upon the rock shaft 44. By this means the shaft 36 may be shifted longitudinally to engage or disengage the driving connection with the pinion 38 in an obvious manner. Mounted in a vertical bearing 45 in the housing 32 is the shaft 46 which is preferably connected with the wringer. Se-

.1 cured to the shaft '46 at its lower end is the beveled crown gear 47 in mesh with the pinion 38 whereby the pinion 38 when in driving connection with the pulley 37 drives the gear 47 Upon the lower face of the gear 47 is secured a journal 48 by means of the bolt 49, washer 50 and nut 51. Revolubly mounted upon the journal 48 is the gear 52 in mesh withthe internal gear 53 which forms a depending extension of the housing 32. It is to be noted that the pitch circle of the gear 52 does not intersect the axis of the gear 53. Therefore the gear .52 does not'occupy the same relative position during successive revolutions of the gear 47 In other words, the planetary pinion contains a number of teeth unequal to onehalf of the total number of. teeth in themternal gear, and therefore the action is not. I cyclic but a traverse 1s caused because the axis of the gear .52 will occupy different positions uponsuccessive revolutions of the gear 47 The gear 52 has seated therein and secured thereto the journal 54, which pro- "jects downwardly below the plane of the internal gear 53 and forms a crank pin for the pitman 55 which, at its other end, terminates in the rack 56 in engagement with the pinionf14. The rack 56 is provided with inwardly projecting flanges 57 at its top and bottom which embrace the pinion 14 and keep , I the rack 57 in proper alinement therewith.

The back of the rack57 is inmore or less loose contact with the rounded edge of the web 30 hereinabove described, whereby the rack 57 may pivot on the web 30 being kept at all times in engagement with the pinion 14 thereby.

In operation and assuming that the rock shaft 44 is rocked to the left from the position shown in Fig. 1 so as to engage the pinion 38, the rotation of the driving shaft will continuously drive the beveled crown gear 47 This will cause the gear 52 to be trailed around inside the internal gear 53 and thus both revolve with the gear 47 and rotate on the journal 48 on'account of its engagement with the internal gear 53. The

rotation of the gear 52 upon its own axis will, by means of the pitman connection, cause the rack 56 to be reciprocated correspondingly oscillating the shaft 13 and therefore the dolly in the washing machine.

superposed upon this motion, however, is

the revolution of the gear 52 as it is carried around by means'of the crown gear 47. This latter movement will obviously cause the pitman 55 to move backwardand forward periodically while it is reciprocating and will thus cause a periodic backward and forward rotation of the pinion 14 and therefore of the dolly, in addition to the oscilla- Having now described my invention I claim:
