To all whom it may concern:

Be it known that Lao B. HART, a citizen of the United States, residing at Vinton, in the county of Benton and State of Iowa, has invented certain new and useful Tmprovements in Washing and Drying'Machines, of which the following is a specificatlon.

My invention relates to a combined Washing and drying machine.

An important object of the invention is to provide a machine of the above mentioned character, having means whereby the rotatable clothes holding element or drum may be held in a horizontal position, and turned, to wash or rinse the clothes, and then shifted to a vertical position, and rotated, to cause the clothes to be dried by the action of centrifugal force upon the wet clothes.

A further ob'ect of the invention is to provide a machine of the above mentioned character, which is convenient to adjust in its operation.

A further object of the invention is to provide a machine of the above mentioned character, which is strong, durable, and reliable in operation.

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

In the accompanying drawings forming a.

part of this specification, and in which like numerals are employed to designate like parts throughout the same,

. Figure 1 is a central vertical longitudinal section through a machine embodying my invention, parts being in elevation,

Figure 1 is a side elevation of a bearing plate and associated elements, parts in section,

Figure 7 is a plan view of the driving shafts, associated elements being in section,

Figure 8 is a detail section through the bearing sleeve and associated elements, parts broken away,

a perspective view of the drum .wlth the diverging arms Figure 9 is a perspective view of the supporting yoke for the bearing sleeve,

Figure 10 is a similar view of a latch device for the lever.

In the drawings, wherein for the purpose of illustration is showna preferred embodiment of my invention, the numeral designates corner posts preferably formed of angle iron, and projecting downwardly in the form of legs 16. These corner posts are connected by

transverse bars

17 and 18, and

also by longitudinal bars 19. These posts and the bars constitute a supporting frame for the machine.

Suitably mounted within the supportin frame is a casing 20, which may be formed of sheet metal or the like, while an other. suitable material may be employe The upper portion of this casing constitutes a drying chamber 21 while its lower portion is in the form of a water holding chamber 22, serving as an ordinary tub. The chamber 21 projects longitudinally beyond the chamber 22, at one hangin bottom wall 23 and a diagonal wall 24, as s own. This arrangement afiords an exterior space 25 for the reception of the motor and other operating elements, to be described. The top-of the chamber 21.1may be closed by means of a cover 26, which is hin ed to the frame at 27, and may be held in the closed position by a latch 28, or other suitable means. There is a space 29 within the frame, exteriorly of the casing 20, and this space is adapted for the reception of driving means, to be described. This space may be closed by'a door 30, hin ed to the frame at 31,'Figure 4, and held 0 osed by a latch 32, or the like.

The numeral 33 designates a sleeve bear- I ing, which is mounted to swing in a vertical plane, longitudinally of the mach ne, and to assume horizontal and vertical positions. This sleeve bearing extends through and 1s rigidly clamped within a collar 34, integral tiall ii-shaped supporting yoke 36. The armg 35 are provided at their ends with horizontal extensions .37, which are pivotally mounted in bearings 38, r gidly secured to the casing 20,- b any suitable means. One of the horizonta extensions 37 1s r1g1dly connected with a lever 39, operating in proximity'to the side of the casing'20 and end, providing an over 35 of a substanthe latch element is depressed, to permit of the movement of the lever. By this means the support yoke 36 may assume horizontal and vertical positions,icarrying the sleeve bearing 33 with it, as is obvious. It is thus seen that the sleeve bearing 33 is supported by this yoke, and the strains-placed upon the sleeve bearing are in turn transmitted. to the support yoke 36.

The sleeve bearing 33 projects into the interior of the casing 20, and passes through the diagonal wall 24, and it is desired to ef-- feet a water tight connection between this sleeve bearing and the diagonal wall. To accomplish this, the sleeve bearing 33 is provided with a ball 43 formed integral therewith, and this ball is pivotally mounted with a plate 44, having a spherically curved face to contact with the ball. The

. plate 44 is secured to the wall by bolts or Cal rivets 46 or the like. The ball 43 is equipped with trunnions 47 pivoted within sockets 48, formed on the plate 44. The numeral 49 designates a ring of packings, preferably arranged upon the outer side of the plate 44, and contacting with the ball 43 to effect a water tight joint.v Tt'is obvious that the detailed construction of the joint may be varied, as may be found advanta eous.

he numeral 50 designates a spindle, rotatable within the bearing sleeve 33, and engaging bearin balls 51 held in place by caps 52 or the li e. This spindle 50 is provided with a ring 53, rigidly mounted thereon, to enga with the bearing balls 51, thus constituting an end thrust bearing, which is particularly needed when the spindle is operating in a vertical position. The. spindle is therefore free to rotate within the bearing sleeve 33, but cannot partake of restricte longitudinal movements therein.

Preferably formed integral with the inner end ofthe bearing sleeve 33, Figures 1 and 6, is an approximately .U-shaped drum yoke 54, embodying arms 55. These arms are adapted to extend upon opposite sides of a drum 56, as clearly shown in Fi re 4. The arms 55 are provided at their ends with headed studs 57 for insertion within transverse notches 58, formed in the ends of a resilient latch bar 59, pivoted to a head or end of the drum. The latch bar 59 is pivoted u ona trunnion 59, rigidly secured to t e head 60, and this trunnion is adapted tov enter a U-shaped bearing 60', secured to the side of the casing 20. This head is provided wi h a flang 6 toenter the open end of the drum, and the latch bar 59 is thus connected with the yoke 54, to hold the head upon the drum in the closed position. By virtue of the flange 61 of the head 60, and associated elements, it is apparent that the yoke 54 constitutes a connecting means between the outer end of the drum and the bearing sleeve 33.

The opposite end 62 of the drum 56 has a base or late 63 rigid] secured thereto, and this p ate is equipped having an opening 65, which is square in cross section, to receive the end 66 of the With a socket 64,

spindle 50, which end is also square in cross I section. It will be further seen that the yoke 54 and associated elements serve to retain the socket 64 upon the end 66.

The drum 56 is preferably of the shape shown, having a cylindrical intermediate portion 67, and diagonalportions 68. The

periphery of the drum is preferably apertured, as shownat 69. As clearly illustrated in Figure 1, when the drum is in the horizontal position, it operates Within the water in the lower chamber 22, but when the drum is shifted to the vertical position, as indicated in dotted lines in Figure 1, the drum is in the upper chamber 21.

Rigidly mounted upon the outer end of the spindle 50 is a combination gear 70, hav ing a cylindrical gear portion 71, and a beveled gear portion 72.

The combination gear 70 is of course an integral casting, and its cylindrical gear portion 71 is adapted for engagement with the segmental gear or gear element 73, Figures l and 2, when the spindle 50 is shifted to thehorizontal position. The segmental ear 73 is pivotally mounted upon the Stud 74, carried by the transverse bar 17. The segmental gear 73 is adapted to be oscillated, by means to be described, and the diameter of the segmental gear 73 being much larger than the diameter of the cylindrical gear portion 71, the spindle 50 will be given a pluralit of rotations in one direction, and then a p urality of rotations in the opposite direction, alternately. The segmental ear 73 has a pin 75 secured thereto, near 1ts periphery, and this pin has pivotal connection with a pitman 76, extending downwardlyand arranged upon the inner side of a large driving gear 77. The pitman 76 is pivotally connected with the gear 77 by means of a .pin 78. The distance between the pin 78 and the pivotal support 79 of the gear 77 is much less than the distance between the pin 75 and'the pin 74, and hence as the gear 7 7 is driven continuously in "the same direction, the pitman 76 will effect memes The power shaft 82 is equipped with a pinion 86 in permanent engagement with the gear 77. i

The power shaft 81 has a vertical beveled gear 87 rigidly mounted thereon, and adapted to be engaged by the beveled gear portion 72, when the combination gear is swung to the vertical position, as indicated in Figure 1.

The numeral 88 designates a motor,

-mounted upon a platform 89, in turn at 'tached to the frame work of the machine,

and located in the space 25. This motor drives a pulley 90, engaging and driving a belt 91, extending downwardly to engage a pulley 92, which is free to turn upon the adjacent ends of the

power shafts

81 and 82, but cannot partake of perceptible longitudinal movement thereon. This pulley is provided With oppositely arranged clut h faces 93 and 94, adapted to have frictional engagement with clutch heads 95 and 96 respectively. These clutch heads are keyed upon the

shafts

81 and 82 respectively, so that they may move longitudinally thereon, and turn therewith. The clutch heads 95 and 96 are urged toward each other by springs 97 and 98, as shown. The clutch heads 95 and 96 are engaged by .ashifting fork 99 carried by a lever. 100, pivoted at- 101. The springs 97 and 98 tend to return the clutch heads to the neutral position, so that both clutch heads may slide with the clutch faces of the pulley 92. When the lever 100 is swung from this neutral position in either direction. one clutch head will have frictional engagement with the clutch face of the pulley, while the other clutch head will disengage the correspond ing clutch face. It is thus seen that means are provided whereby the pulley 92 may be employed to alternately drive either

power shaft

81 or 82, or the pulley 92 will run idle without rotating these power shafts.

The operation of the machine is as follows: With the spindle 50 in the vertical position, as indicated in dotted lines. in Figure 1. the lcad or cover 60 of the/drum may be removed and the clothes or the like to be washed introduced into the drum. The head is now looked .to the drum by engaging the latch bar 59 with the headed studs 57. The

lever 39 is now shifted to the horizontal position, Figure 5, and the drum 56 will as sume a horizontal position, with its lower the lever 100 is swung in the direction to cause the clutch head 96 to frictiona-lly engage the clutch face 94. The motor 88 will therefore drive the gear 86, which in turn will drive the gear 77, effecting an oscillatory movement of the segmental gear 73. This segmental gear engaging the cylindrical portion 71 of the combination gear 70, will rotate the drum 56 for a plurality of rotations, alternately, in opposite directions. The power shaft 81 is now idle. After the washing operation is completed and it is desired to dry the clothes. the lever 100 is returned to the neutral position. The

.lever 39 is now swung to the vertical position. whereby the spindle 50 and the drum assume the vertical position shown in dotted lines in Figure 1. The beveled portion 72 of the combination gear now engages the beveled gear 87. which is adapted to drive the spindle and the drum at an increased speed. The lever 100 is now shifted to bring the clutch head 95 into engagement with the clutch face 93, and the motor will therefore drive the power shaft 81. The drum rotating at a high speed, subjects the wet clothes to the action of centrifugal force whereby they are dried in a manner well known in the art.

After the drying operation. the rotation of the drum is stopp d, and the clothes may be removed, as is obvious.
