WASHING-MACHINE MECHANISM.

Specification of Letters Patent. Patented Sept. 18, 1917.

Application filed March 29, 1916. Serial No. 87,400.

To all whom it may concern:

Be it known that I, HERMAN C. DOMAN, a citizen of the United States, and resident of Oshkosh, in the county of Winnebago and State of Wisconsin, have invented new and useful Improvements in lVashing-Machine Mechanism; of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in washing machine mechanism.

It is one of the objects of the present 1nvention to provide a washing machine mechanism for changing a rotary movement of a driving shaft into a rocking and reciprocal movement of a pounder shaft.

A further object of the invention is to provide a washing machine mechanism having a. horizontal driving shaft and a'vertical pounder in which the parts coact to permit the easy disengagement of the driving means from the driven means.

A further object of the invention is to provide a washing machine mechanism in which a yielding connection between the horizontal and the vertical shafts performs the two fold function of transmitting a rotary movement into a rocking and reciprocal movement and also serves to hold two shaft sections separably connected together.

A further object of the invention is to provide a washing rna chine mechanism which is of simple construction, is strong and durable and is well adapted for the purpose described.

With the above and other objects in view the invention consists of the improved washing machine mechanism and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views: 45

Figure 1 is a top view of a portion of a washing machine on which the improved mechanism is mounted, part of the mechanism being shown in section;

Fig. 2 is a vertical sectional view thereof taken on line 2-2 of Fig. 1;

Fig. 3 is a front detail view of the washing machine and mechanism;

Fig. 4 is an end detail view of one of the shafts; and

Fig.6 is a detail view of the cross head. Referring to the drawing the numeral 5 indicates the tub or receptacle which is provided with a top portion 6 and a hinged cover or portion 7. The receptacle 5 is preferably formed of metal and is of rectangular shape and the hinged cover 7 is adapted to be opened to remove or place clothes within the tub. 'An angular bracket 8 mounted on the top and side portions ofthe tub is provided with an upper horizontally extending bearing 9 and a vertically extending slotted side portion 10. A horizontal driving shaft section 11 extends through the upper bearing 9 and on its outer end portion is provided witha sprocket Wheel 12 and a cranked arm 13. The cranked arm 13 is provided for manually rotating the shaft and the sprocket wheel is used for transmitting motion to a fly Wheel 14 which is journaled on a short stud shaft 15 engaging the slotted portion of the bracket 8. This stud shaft 15 is formed with a collar 16 which bears against the bracket on each side of the slot and a nut 17 threaded on the inner end of the stud shaft and bearing against the inner face of the bracket adjustably clamps the shaft in position. A small sprocket wheel or pinion 18 also journaled on the stud shaft is attached to and turns with the fly wheel and has a chain connection 19 with the sprocket wheel 12 of the driving shaft 11 and is driven thereby. The elongated slot in connection with the stud shaft provides for taking up wear of the sprocket chain by increasing the distance between the two shafts.

The-inner end of the driving shaft 11 terminates at a point to permit the hinged cover to be swung to open position without striking against the said shaft and has mounted thereon a recessed clutch'member 20. The recess 21 of said clutch member is ofrectangular form and is slightly tapering longitudinally with relation to the shaft to perm-it the easy entrance of the complementaryclutch member 22. The clutch member and the s; rocket wheel also serve as collars on the driving shaft and are positioned to bear against the opposite end portions of the upper bearing 9 to prevent endwise movement ofsaid shaft. This last mentioned clutch member is mounted on the outer end of a supplemental driving shaft section 23 which is in axial alinement with the driving shaft 11 and is rotated thereby. The supplemental driving shaft '23 is journaled in the upper bearing 24:- of a bracket 25 which is mounted on the hinged cover or portion and is moved therewith. The bracket 25 extends to a point adjacent the central portion of the cover and is provided with two upstanding guide rods 26 on which is slidably mounted areciprocal cross head 27. A reciprocal pounder or Work shaft 28 having a pounder 29 within the tub and mounted on the lower end of the shaft extends vertically through the hinged cover and the bracketand between the upstanding guide rods and a't its upper end is rockingly connected to the cross head 27 by a horizontally extending arm 30. The inner or hub end of the arm extends into the elongated recess 3l'of the cross head 27 and the upper end portion of the pounder shaft extends revolnbly through the cross head and through the interposed hub portion of the arm and is pinned to .said arm. This construction permits the arm to rock the pounder shaft while it is being reciprocated vertically. The outer end portion of the arm 30 is formed with a spherical end or ball 32 which enters a socket 33 provided in the outer end of an arm 34 pivotally mounted on the inner end of the supplemental shaft 23. The pivotal arm 34 is formed with a recess 35 into which extends an arm 36 which is mounted fast on the in-- her end portion of the supplemental shaft 23 by the same pin 37 which pivotally connects the arm 34 to said shaft. A coiled spring 38 interposed between the two

arms

34 and 36 and extending into a recess 39 performs the twofold function of holding the socketed member in engagement with the ball shaped end of the pounder shaft arm and also to yieldingly hold the two clutch members operatively in engagement with each other. It will be noted that the distance between the complementary clutch member 22 and the arm 36 is greater than the length of the bearing 24 to permit the reciprocation of the supplemental shaft in engaging and disengaging the complementary clutch members.

I The bearing 23 is formed in two parts and the space 23 between the parts permits a washer 40 to be mounted on the shaft and which washer bearsv inwardly against a transverse pin 41 extending through the shaft.

A clutch control push and pull member 42 slidably extending through acasing 43 covering the portions of the mechanism is provided with a bifurcated wedge portion 44 on its lower end which straddles the supplemental shaft between the washer and one of the parts of the bearing 24 and forces said supplemental shaft inwardly against the pressure of the coiled spring 38 and dis-.

engages the clutch members. A coiled spring 44 having its upper end connected to the casing and its lower end connected to the control member holds the said control member in its upper position when the two shafts are in clutching engagement. The pivotal arm 34 and the coiled spring 38 compensate for the varying distance between the said pivotal arm and the pounder shaft during the reciprocal and rocking movement of said shaft.

While a cranked handle is shown for turning the drive shaft it is to be understood that the shaft may be rotated by power means if desired.

In operation the turning of the crank arm will reciprocate and rock the pounder shaft and the fly wheel connection will tend to steady and give a more uniform motion to the parts. If it is desired to raise the cover of the tub it is only necessary to push downwardly on the control member to separate the clutch member and the cover may then be swung upwardly to open position. After the cover is swung to closed position and it is desired to further operate the pounder the clutch member is pulled upwardly to permit the spring of the pivotal arm to force the slidable clutch member into engagement with the other clutch member and the parts may then be operated as before by turning the hand crank.

From the foregoing description it will be seen that the washing machine mechanism is of-very simple construction and is well adapted for the purpose described.
