DRUM CONTROL FOB WASHERS.

Application filed January 8, 1923. Serial No. 611,459.

This invention relates to improvements in mounted about operating shaft 10. Intermechanism for controlling the rotary drum of a washing machine.

The resent invention relates to that type of was g machine in which there is provided a drum rotatably mounted within the casmg, together with mechanism for automatically reversing the direction of rotation of the drum so as to give the drum alternate direct and reverse movement, as is well known in the art, and is an improvement upon the invention described and claimed in the prior patent to- G. Binder, No.

1,160,687, granted November 16, 1915.

The objects of the present invention are to provide this .type of washing machine with improved means for simultaneously disconnecting the rotating means of the drum and applying the brake thereto; to provide a single actuating member which is easily accessible to the operator for the purpose of eflectin such operations; and furthermore to provlde means readily accessible from the same position of the operator for causing manually controllable actuation of the drum in either direction so as to properly position the same for unloading and reloading after the automatic rotatin and reversing means has been disconnecte all for the purpose of conveniently inching thedrum into position with its door in registry with the easin door. %ther objects of this invention will appear from the following description and claims when considered together with the accompanying drawings.

Fig. 1 is an elevation of my improved machine taken from the right-hand end thereof; Fig. 2 is a detail sectionalview of the brake mechanism; Fig. 3 is a front elevation; Fig. 4 is a detail sectional view of the right-hand end of my device taken on line 4-4 of Fig. 1; Fig. 5 is a detail sectional view of the header mechanism taken on line 55 of Fig. 6; and Fig. 6 is a detail sectional view of the header mechanism taken on line 6-6 of Figs.

3 and 5.

Casing 1 is suitably supported upon a standard or le s2and1s provided with doors 3 through whic access may be had to doors 4 provided .upon drum 5 which is rotatably mounted within the casing. The means for rotating the drum comprises reversely driven belts 6 and 7 which extend about freely mounted pulleys 8 and 9 which are loosely mediate driving pulley 11 is fixed upon shaft 10 and is adapted to be driven by either of belts 6 and 7 by shifting the same alternately back and forth in a manner to be described. Pinions 12 provided upon the ends of shaft 10 mesh with gears 13 which in turn mesh with and drive main gears 14 which are fixed upon the shaft of drum 5.

Pulley 9 is referred to also as the worm pulley, since it is provided with worm section 15 to be operated therewith. Meshing with worm 15 is worm wheel 16 upon shaft 17, upon which there is mounted a cam member 18. This cam member is adapted to alternately engage rollers 19 which are mounted upon the forked end portions of rock arm 0 which in turn is pivotally mounted in the me of the machine at point 21. Suitably mounted at point 22 there is provided also rock arm 23, the lower end of which is provided with lugs 24 for engagement in and cooperation with cut-out portions 25 of rock lever 20. The upper end of rock arm 23-is adapted to engage in cut-out portion 26 of belt-shifting cam member 27 so as to give reciprocatory -movement to the same during operation of the machine.

This cam member is mounted upon and carried by belt shifting rod 28 which is suitably mounted in bracket 29 of the machine frame for reciprocatory movement with the cam member. The other end portion of rod 28 hasfixedly'mounted thereupon'bracket 30 through which extends pin 31 carrying belt-shifting bracket 32 which has slots 33 and 34 through which the belts extend for transverse movement thereby. Thus it will be seen that during operation of pulley 9,,rock arm 23 through the connections just described will effect a reciprocatory movement of cam member 27 and hence of rod 28 so as toroduce a like movement of belt shifting racket 32 and automatically shift belts 6 and 7 alternately into driving engagement with driving pulley 11. Belt 7 is sufliciently wide to at all times engage pulley 9 and hence ensure operatlon of the worm pulley without interruption. In this way, the direction of drive 1s automatically reversed so as to give reverse movement to the rotatable drum in the casing.

As a means of disconnecting this automat-ic reverse drive mechanism at the time by means of otally mounted at 'upon bracket 41.

ly mounted upon rod 28 and which has meshin en'gagementwith segmental rack 36 carried y arm 37 which in turn is pivotally mounted about bracket 29. Arm 37 is adapted to be actuated by meansof rod connection 38, the other end of which is manipulated handle 39 which in turn is piv- Spring-pressed pin 42 is adapted to snap into engagement with recess 43 provided in one end portion of slot 44 so as to lock handle 39 in set position, this latch mechanism being adapted to be released b means of finger 44" pivoted upon the ban Is for the purpose of releasing pin 42. Cap member 45 serves to secure bracket 29 to the main bracket or frame of the machine structure and sup-' rts also housing 46 for the brake mechani'sm. Mounted within brake housing 46 there is provided brake drum 47 which is bolted to pinion 12 at this end of the machine and is connected to shaft 10 by means of a spline connection indicated at 48. Housing 46 serves also to su port stud 49 which carwhich is adapted ries at its inner en cam member 50 for onwith brake shoes 51 which are in this we. adapted to be thrust radially and outwar y against the brake drum against the tension of spring 52. The cam member is actuated by means of suitable .rod connections indicated in a general wayby reference numeral 53 nected with the sa used to actuate rack member 37. Thus I have provided a single means for releasing the automatic reverslng mechanism and at the same time applying the brake so as to etc .the drum.

urthermore, I have to be actuated by the operator so as to enable'him to accurately position the drum with'respect to the doors of gagement the casing for unloading and reloading after comprises lever p 60 of lever arm the automatic operating means has been disconnected, as just referred to. This means arm 54. which has forked end 55 engaging between fixed collar 56 on rod 28 and friction disc .57 on the end of pinion 35. Handle member 58 which is suitably mounted in bracket59 has an arm 58' which engages in recess or cut-out portion 54 so as toenable the operator to actuate the same for endwise movemember has been disconnected from t e operating mechamsm of the machine.

Assumin the drum to be in operation, and

' assuming t at the operator wishes to sto manipulation of handle 39- wi the machine,

connectlons above described,

through the cause rod 28 to rotate so as to disengage the belt shift' cam member from rock-arm 23. Belts 6 an 7, as shown in the drawing, occupy idle positions, but should either of them occupy driving relation with respect to oil the brake, reaches registering position with the casing which in turn are con;

provided a means a .door, ment of rod 28 afterthe belt shiftln cam o controlling means operatab operator for producing rotation "efiective upon said same, and operator operated controllin driving pulley 11, such rocking movement of cam member 27 will automatically shift the belt to idle position by virtue of engagement of cam member 27 with one of cam lugs 27. Such manipulation of handle 29 will at the same time apply the brake to stop the drum. To inch the drum into position with its doors in registry with the door openings of the casing, the operator, after. opening the casing door, rod 28 in either direction to rotate shaft 10 sufiiciently to bring the drum to the desired position. This adjustment is of course effected after manipulating handle 39 to slack and as soon as the drum door door, the brake is again applied by operatinghandle 39, after which handle 58 is at once operated to stop further drum drive.

The mechanism described is of particular value in connection with a Washing or like machine in which a rotatable work carrying drum is reversely rotated during machine operation, such as for a washing treatment. Not only does the momentum of the drum increase thedifiiculty of inching to proper registering relation but, alsoythe load in these drums shifts around, and usually does so by sudden movements, requiring mechanism capable of qulck and accurate control and operation if exact registration is to be S What I claim is I 1.
