LAUNDRY APPARATUS.

Application'filed March 29, 1920. Serial No. 369,499.

To all whom it may concern:

Beit known thatI, HARRY O. BARTLETT, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented certain new and useful Improvements in Laundry Apparatus, of which the following is a specification.

My invention relates to washing apparatus, for laundry purposes, and has particular reference to such apparatus in the nature of an attachment, to be applied upon or used in connection with the ordinary stationary laundry tub, while not necessarily restricted to this use.

An important object of the invention is to provide an attachment of the above mentioned character, which may be installed upon the ordinar stationary laundry tub, without altering tlie construction of the tub, or injuring the same.

A further object of the invention is to provide apparatus of the above mentioned character, which is of simple construction, strong and durable.

A further object of the invention is to provide means whereby the movable drum may be removed from the tub, without disturbing the driving means or gears.

A further object of the invention 1s to provide a hanger bearin having means to guide the trunnion of t e drum, upon its downward movement, and to also shift the drum longitudinally, whereby the drum will be properlytconnected with its driving gear.

A further object of the invention is to provide means for locating and supporting a motor, and associated elements, outwardly of or beneath the forward inclined side of the laundry tub, whereby these elements occupy this space and are protected or covered, and an upstanding driving shaft is properly located and may be employed to ad ustably support a wringer, in a proper position for coaction with the several compartments of the tub.

A further ob'ect of the invention is to' provide a mova le orrotatable drum, having interior lugs or projections disposed in a peculiar manner, to prevent the clothes or laundry from being unduly tangled or knotted.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 15 designates an ordinary stationary laundry tub,

supported by legs 16. This tub has a forward inclined side l'Z, as is customary, for

with the partition 18, preventing displacement of the strip. 22. As clearly shown in Figure 2, a transverse head 24 is formed integral withthe forward end of the strip 22, and contacts with the upper edge of the side 17, and serves as a brace to prevent the supporting frame from turning on its axis. This head carries a vertical or depending flange 25, preferably formed integral with the upper end of an inverted Y-shaped member 26, embodying spaced vertical arms 27. At their lower ends, as shown in Figure 3, the arms 27 are bent inwardly forming hori-' zontal extensions 28, serving to support a platform 29, for a purpose to be described.

The arms 27 are preferably reinforced by.

longitudinal ribs 30, whereby these arms are stitl'ened,.to prevent vibration, and are T- shaped in cross-section.

At the upper end of the arms 27, is an inwardly bent or formed apertured ear 31, having connection witha section of a cable 32. This section of cable isconnected with one screw-threaded element 33, of a turnbuckle 34, the other screw-threaded element of which is connected with a cable section 35, passed beneath the tub, as shown in Figure 3 and provided at its free end with an eye-bolt 36, arranged within an elongated slot 37 in the free end of the strip 22. The bolt is therefore adjustably connected with this strip, whereby the cable may be employed in securing the supporting frame to the tubs of slightly different widths.

The numeral 38 designates a housing or casing, preferably cast integral with the strip 22 and head 24, at the forward end of the strip, and preferably cylindrical. This housing is preferably vertically arranged, and has a cap 39, detachably see cured thereto by screws 40 or the like.

A depending bearing 41 is carried by the lower end of the housing 38, and receives therein a vertical combined driving and pivot shaft 42, having its lower end journaled in a gear casing 43, rigidly secured to the platform 29, as shown. This gear casing encloses a worm wheel 44, rigidly secured to the shaft 42, and engaging a worm 45, upon a shaft 46. Theshaft 46 is connected with the armature shaft 46', by a friction clutch device, embodying a block 48', preferably formed of wood, and having a radial slot to receive the ends of these shafts. The block 48' is surrounded by a metallic band 49, having depressions 50 therein, and apertures 50, receiving a bolt 51', passing through the ends 52'. B tightening up the nut upon the bolt the clamping engagement upon the block and shafts may be adjusted.

As clearlyshown in Figure 5, the verti cal shaft 42 carries a bevel gear 48, rotatable thereon, and engaging a bevel gear 49, angularly arranged, and secured to a diagonal shaft 50, journaled through a bearing 51, near its upper end. This diagonal shaft hasits lower portion slightly reduced, as shown at 52, forming a shoulder 53. the reduced portion 52 being journaled in a bearing 54, preferably formed integral With a depending arm 55, preferably integral with the strip 21, and flange 23. A bevel gear 56 is secured to the reduced portion 52, by aclamping screw or bolt 57, and this bodying an L-shaped head 64, to straddle the end of the tub, and be clamped thereto by a bolt 67. This hanger hearing, as shown more clearly in Figure 6, is provided with an interior groove 68, which is tapered, and

.decreases in width downwardly. The end of this groove terminates in a bearing 69, and an inclined wall is arranged adjacent the bearing 69, and projects inwardly.

The numeral 71 designatesa drum as a whole, embodying heads 72, and a periphery 73, including a removable cover 74, held closed by any suitable means. This periphery may be formed of spaced slats. In Figure '17, slats 73', of a modified form, are shown, which are adapted to form the periphery of the drum. These slats have perforations 74'. The slats may be opened at 74', in Figure 14. Arranged within the drum are longitudinal agitator bars '75, four of which may be employed, as shown, and these bars may be diametrically arranged. Two of the diametrically arranged bars have inwardly projecting extensions or lugs 76, equidistantly spaced from their ends, while one of the remaining bars has a corresponding lug 77 at one end, and the other 'bar has a lug 78 arranged at the opposite end of the drum. The function of these projections or lugs is to prevent the clothes being washed, frombecoming .unduly tangled or knotted.

A coupling member 79 is suitably secured to one head 72, by screws or the like, and is provided with a socket 80, polygonal in y cross-section, to receive the extension 61. A

coupling member 81 is secured to the opposite head 72, and carries a trunnion 83, which is cylindrical, and adapted to operate within the groove 68. 'When the drum is lowered into the tub, the trunnion 83 may be conveniently placed within the upper wide end of the groove 68, and the extension 61 inserted within the socket 80, or its reduced end 62 inserted therein. When the drum approaches the lowermost position, the trunnion 83 contacts with the inclined wall 7 O, which shifts the drum longitudinally to the right, whereby the extension 61 becomes gear casing completely inserted within the socket 80. It is thus seen that the drum is connected with the gear 58 and will be driven by the motor 47, through the medium of the interposed gearing.

As more clearly shownin Figure 5, a lever 83' is pivoted to the housing 38, and projects therebeyond, and serves to shift a clutch element 84, keyed upon the shaft 42, to move longitudinally thereof and turn therewith. This lever may be locked in adjustment by any suitable means. The clutch element is adapted to engage a coacting clutch element 85, rigidly secured to the bevel gear 48. It is thus seen that when the clutch element 84 is in the lowered position, the gear 48 will be locked to its shaft.

The shaft 42 projects upwardly beyond the cover 39, into an annular flange 86, formed integral with the cover, the upper portion of the shaft being formed polygonal in cross section, numeral 88 designates a gear casing or housing of a wringer, to be described, and this housing carries a depending annular flange 89, pivotally receiving the flange 86, as

clearly shown in Figure 5. This flange 89 is provided at its lower end with slots 89', preferably four in number, arranged 90 apart, and adapted to receive a sliding bolt 90, carried by the cover 39, and shifted by a handle 91'.

The numeral 99 designates a 'wringer as a whole, secured to the gear casing 88. This \vringer embodies a pair of rolls 100, suitably driven by the gears (not shown), in the 88, and these gears are driven by a coupling shaft 101, adapted to engage the polygonal end 87, as shown in Figure 5.

The operation of the apparatus is as follows:

The motor 47 may be set into action by the usual switch, and the shaft 42 will be driven. By shifting the clutch element 84 downwardly. the bevel gear 48 will be locked to its shaft, and the drum 71 rotated.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub joined claims.
