GEABING FOR WASHING MACHINES.

Application led February'S, 1926. Serial No. 85,760.

This invention relates to mechanism for tub rests. Inside of this tubular frame memoperating washing -machines and consists ber 4 is a tubular sleeve 5 and within the in Ithe devices and combinations of devices sleeve is an operating shaft C. The tubuherein illustrated, described and claimed. lar sleeve 5 is provided between its ends with 5 In the accompanying drawings: v an annular flange 6, the lower surface of 60 Fi e 1.`s a plan view of the device em- Which forms a shoulder bearing for a suitbodying our invention, detached fromv the able washer 7 which rests upon the' bottom machine.

The shaft vention is enclosed within a housin A, the 428 projects upwardly through a suitable 105 upper part 1 of which is secured to t e lower bearing 30 on the housmg A and upon its part 2 inv a familiar manner by nuts and upper end, outside'the housing, 1s secured bolts 3, 3. Rising from the top member 1 of a .short lever 31.l When the lever 31 is the housing, is a Itubular frame member 4 on moved, the shaft 28 is rotated 1n the desired the upper ge of which the bottom B of the direction, and in operation, through crank 11o 69 vided with a suitable apertur'ed lug 43 to sitioned that when its rear surface 34 bears against the roller 33, the shoulder of the lug 35 will bear against the inner surface of the flange 36 on the arm 24. Thus, as the arm 24 moves about its pivotal axis at 23, the rack bar 14 will have sliding contact with the flange 36, and a rolling contact with the roller 33 of the arm 24.

Again referring to Figure 4, it will be seen that the rack bar 14 is indicated as being enmesh with the spur gear 12 in one position of the rack, and by referring -to Figure 5, it will be seen that the rack 14 is out of mesh with the gear 12. When the arm 24 is swung by the action of lever 31 from the position shown in Figure 5 to the position shown in Figure 4, it will be understood'that the rack 14 will instantly mesh with the spur gear 12, and vice versa, and, also, that when the rack 14 is swung into the'position shown in Figure 5, its reciprocating motion due to the' action of the crank cam 15, may continue without any danger of it` engaging with the spur gear 12, the rack oscillating [back and forth between the roller 33 and ,flange 36.

Referring now to Figures 1, 2 and 3, it will be seen that the housing A is provided with a tubular, housing member 37 whichv serves as a support for the wringer, not

shown. The shaft 39 is provided on its upper end with suitable means for transmitting its motion to the wringer mechanism,

said means in this instance being a bevel wheel 41. The top portion of the wringershaft housin 37 is enlarged, as shown at 42, to accommo ate the bevel gear 41 or other wringer operating mechanism employed.

i The outside of this enlarged part 42, or the upper portion of the housing 37, will be proform a bearing support for a vertically dis'- posed operating lug 45 on top of the housing. A handle H on rod 44 will be conveniently disposed for rod 44, ythe lower end of; which will be suitably held in an aperturedl the use of the operator to rotatethe rod 44. Upon the lower end of the 'rod 44 is mounted a lever 46, and a link rod 48 connects the two levers 31 and 46, so that by the operator moving thehandle H in a desired direction, he will, through the rod 44, levers 46- and 31, and connected parts above referred to, swing the arm 24 in the desired direction to cause the rack 14 to mesh with or to bey disconnected from the gear 12.

When the wringer mechanism is to be put' into operation by the use of appropriate means for that purpose, not forming a part of this present invention and therefore not illustrated herein, the motor actuating means will be thrown into action and the shaft 18 and its' extension 39 will of course rotate, and the operator will actuate the handle H in the appropriate direction -to cause the arm 24 to swing and disconnect ,the rack 14 from gear 12. Being thus in the position illustrated' in Figure 5, the rack will travel idly, while the shaft 39 is actuating -the wringer mechanism; and the washing element 11 within. the tub will be idle, also, thus permitting the feeding of the garments from the tub to the wringer without danger of injury to the operator. lt will be manifest, however, that where the wringing of garments from a source other than the tub of the washing machine is required` the rack 14 will be caused to mesh with the gear 12 and thus the washing of one batch of clothes and the wringing of a different batchmay be carried on simultaneously.

On the wringer support and shaft housing 37, suitably spaced apart, are the apertured lugs 47 to which the tub is secured, by means of screw bolts 49 passing through the apertured and outwardly bent ends of the tub bands 50, as more clearly seen in Figure 10.

The upper part 1 of the housing A is .shaped at one end to form av chamber or space for the worm 20 and vworm gear 19, which space is covered by a cap plate 51, the bottom of this chamber beingthe horizontal wall 52 of the housing.' In the cap plate 51 is the plugged oil hole 53, and the oil is allowed to flow into the housing chamber below the wall 52 by means of the oil hole 54 therein.

The chambers within the housing A are designed to be filled with a. proper lubricant. In order that the same shall not riseup on the operating shaft C and work through the bearings, and flow outside the sleeve 5 and thus contaminate the wash Water and cause injury to the clothes being washed, we have devised a very satisfactory method of oil circulation, as follows: Y

i The top portion 1 of housing A is provided with a bottom or wall 55 for the frame member 4 and it is this wall into which the sleeve end is secured, as shown at 8 in Figure 6. Thus an elongated, annular chamber 56 is formed within the frame member 4 surrounding the sleeve 5. An elongated slot 57 is cut` through the wall of the sleeve 5 near the upper part of this chamber 56 and a relatively large opening 58 is cut through the wall (see Figs. 6 and'7). Thus any oil rising around the shaft C will pass through the slot 57 into the chamber 56 and iind its way into the housing chamber through the hole opening 58. o insure, further, that oil will not work up around the shaft. C to a height above the slot 57, the interior of the sleeve 5 is gieater in diameter than the diameter of thev shaft C intermediate its lower part and the bearing 9. The long bearing for the shaft C extends from the bottom of the slot 57 to its lower end, as clearly seen in Fig. 6. w

The tool or washing element 11, actuated by the shaft C, is not herein claimed, as the same is niadethe subject matter ofa separate application, and therefore need not be further described other than to state that it is given a rotary oscillation in opposite directions by the mechanism described.

We claim as our invention:
