Numeral 1 designates an electric motor mounted on a suitable support below a tub 2, of the washing machine, the bottom line of the tub being designated by the numeral 3. The motor 1 is adapted to be brought into driving engagement with a two-faced mit-red gear 4 which is suitably attached to a vertioal driving'shaft 5 ,at its lower end directly underneath a supporting bracket 6. On the shaft 5 at its upper end is adapted to be mounted amitred gear 7 which engages with a mitred gear 8 which is keyed to a shaft element 9. The shafts 5 and 9, according to this invention, are enclosed in a housing 10, which is supported by various means such as, near the gear 4 and bracket 6 and shaft 5 being adaptedto keep the housing 10 from shifting upward; the housing, according to this modifi ation of the invention, is primarily 19-- ported at the bottom in a pocket formed in the supporting bracket 6. The shaft 5 is preferably journaled in a bearing element 14 gageswith alock'inggear element 18 which is adapted to be locked or released by the engagement and disengagement with a pawl 19 actuated by a lever arm 20. The ,objectof this Construction is to permit the housing 1,0.and

larm portion 16 thereof, with all its attachments, to be swung in either direction into any position relative to the machine on which it is supported bymeans of brackets 12 and 6,

by a simple disengagement of the pawl element .19 from the gearing 18.

In order to reverse .the direction of movement of the shafts Sand 9 throughthe twofaced gear 4, a suitable driving mechanism is provided between the driving motor 1 and the gear element 4, preferably as disclosed in Figurel and claimed in this applicants copending application. The housing 10 and its integrally extended arm portion 16 is formed tov properly receive therein the shaftelements 5 and 9 and the gears .7 and 8 and may be constructed either of a plurality of longitudinal one-piece sections securely clamped together by'means of suitable fastening ele .ments or may be formed from one integral pieeeas may be desired, thereby providing a longitudinal one-piece housing which be swung circuitously to the right or left and locked in any desired position. 1 v In the modification of this invention disclosed in Figures 3, 4, 5, and 6, the bearing elements within the housing 21, as at 22, .23 and 24, are preferably cast integrally with either one of the portions which comprise the housing'21 or otherwise as may be desired. The housing 21 is provided with an integrally extcndingarm portion 27, and is so constructed that it may properly receive therein driving shaft elements 28 and 29 and the gears 7 and 8. The housing 21 and 27 is preferably made, accordingto this invention, in two 1ongitudinal onepiecesections 26 and 30 having overlapping joints-31 which may be securely locked or connected together by means of suitable fastening'elementsj32.

The housing member, in this invention, comprising the portions 21 and 27, is adapted to pivotor swing upon a bracket portion 33 securely fastened'to themain body section of the apparatus by means of machine screws or otherwise as at 34 and is held in revoluble vertical position by means of an extended bracket element 34 fastened tothe main body portion of the machine by means of suitable ngiiP- The locking means for retaining the lionsing in a desired position in the modification of the invention as disclosed in Figure 6 comprises a flange element36 having a plurality of notches37, 38, 39 and 40 arranged periphorally thereof, the flange element 36being securely fixed by means -of set screws 41 or otherwise to the housing portion 21. A cooperating interlocking element 42 is arranged in slidable position within the bracket portion 33 in such a manner that when a notched portion 43 in the sliding member 42 is di .rectly opposite the flange member extension 36, the housing v 21 and 27 may be easily revolved into a desired position, and when the notched portion 43 is out of alignment with the flange portion 36, the sliding member 42 will be drawn by spring into one of the notched elements 37, 38, 39 and 40 the flange member 36, thereby securely locking the housing in'the desired position. In order to accelerate the sliding movement of the member 42, asuitable handle portion 44 is connected thereto and extends to a convenient position for manually operating as at 45, the rod 44 being slidably arranged in guide or bracket portions attached to the main body of the machine.
