SAMUEL V. BRAMMER, OF CINCINNATI, OHIO.

WASHING-MACHINE.

Application filed January 27, 1909.

To all whom it may concern:

Be it known that I, SAMUEL V. BRAMMER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in VVashing-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in washing machines.

The object of the invention is to provide a machine of this character having means whereby a current of air is forced through the clothes while being washed.

A further object is to provide a washing machine having an air pumping mechanism adapted to be actuated by and simultaneously with the rubber operating mechanism of the machine whereby the air is forced through the clothes.

1V ith the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a side view of a washing machine constructed in accordance with the invention; Fig. 2 is a vertical sectional view of the same; Fig. 3 is a top plan view; Fig. 4 is a horizontal sectional view taken below the clothes rubber; and Fig. 5 is a bottom plan view of the rubber.

In the embodiment of my invention, I provide a tub or receptacle 1 which is preferably supported by legs 2 secured thereto in any suitable manner. On the upper end of the tub is secured a top 3, one portion of which is hingedly connected to the other portion whereby the hinged portion may be swung upwardly to permit access to the tub. Through the hinged portion of the top 3 projects the upper end of a rubber operating shaft 4, on the lower end of which is secured a clothes rubber 5 which may be of any suitable construction but which is here shown and is preferably in the form of a disk or plate in the under side of which is formed a plurality of suction recesses which have communicating therewith suction passages 7 formed in the disk as shown. The shaft of the rubber is preferably rectangu- Specification of Letters Patent.

lar in cross section and has mounted thereon an operating gear 8. The gear 8 preferably has a sliding engagement with the rubber shaft 4 and the gear is held in an operative position adjacent the upper side of the top 3 by a retaining frame 9 which is secured to the top, as shown.

The rubber 5 is held down in yielding engagement with the clothes in the tub by a clutch mechanism 10 which consists of a sleeve 12 slidably mounted on the squared rubber shaft above the gear 8 and having formed thereon oppositely disposed pairs of apertured bearing lugs 13 between which are pivotally mounted shaft gripping jaws 14, to the outer ends of which are connected one end of coiled springs 15, the opposite ends of which are connected to a cross head 16 secured to the upwardly projecting hub 17 of the gear 8. By means of the clutch mechanism 10, the shaft may be forced downwardly to engage the rubber with the clothes, in which position the rubber will be yieldingly held by the springs 15. The construction of the clutch is such that while the shaft may be readily pushed downwardly, it cannot be moved upwardly without releasing the clutch jaws 14 so that when forced downwardly to engage the rubber with the clothes, the rubber will remain in operative position.

If desired, the upper end of the shaft 4 may be provided with a suitable handle 18 to facilitate the operation thereof.

On the top 3 is mounted a rubber operating mechanism comprising a rack bar 19 which is slidably mounted in suitable bearings 20 and is connected at one end to an operating handle 21 by a connecting rod 22. The handle 21 is preferably hingedly connected to the top adjacent to one edge of the same, as shown. The rack bar 19 is arranged on the top in proper position to engage the gear 8 so that when said rack is reciprocated by the handle 21, the gear will be oscillated and the movement thereof imparted to the rubber 5 through the shaft 4 with which the gear is engaged.

On the top 3 is arranged an air pumping mechanism comprising a cylinder 23 pivotally mounted at one end in suitable bearing brackets 24. In the cylinder is slidably mounted a valved piston 25 having a piston rod 26, the outer end of which is bent at right an les and engaged with the rack bar 19 where y when sald bar is reciprocated by the handle 21, the piston 25 will also be reciprocated in the cylinder. On the outer end of the cylinder is arranged an air discharging nipple 27 with which is connected the upper end of a flexible air conductin tube 28, the lower end of which is connected to an air injecting tube 29 arranged in the bottom of the tub and projecting a suitable distance above and below the bottom, as shown. The portion of the tube 29 which projects above the bottom and into the tub has formed therein a valve seat 30 with which is en aged a ball valve 31 which opens automatically to allow the air topass into the tub but preventsthe air or water in the tub from entering the tube. The upper end of the tube 29 above the valve is preferably provided with a series of perforations or discharge passages 32 and in said upper end is a retaining pin 33 to prevent the displacement of the valve.

In the bottom of the tub is arranged a shield plate 34:, said plate being provided on its under side with a supporting flange 35 which rests on the bottom of the tub. The flange 35 and the shield plate are provided with a series of perforations 36 to permit the water to circulate therethrough. The plate 34 is also preferably provided with radial corrugations around its outer edge as shown in Figs. 2 and f the perforations 36 being arranged in the bottoms or troughs of the corrugations are thus prevented from being closed by the clothes which rest on the ridges of thecorrugations. The upper end of the air injecting tube 29 projects through the shield plate 34 and eX tends a suitable distance above the same to prevent the air forced through said tube from stirring up the sediment in the bottom of the tub and carrying the same back up through the clothes. In order to prevent the clothes from resting on and closing the upper end of the air injecting tube, I provide a guard 37 which may be in the form of an open wire or perforated metal frame which is so constructed to prevent the clothes from closing the upper end of the tube but which will readily permit the air to pass therefrom and through the clothes in the tub.

On a stationary part of the top is preferably secured a wringer attaching plate 38, to which a wringer may be attached so that after the clothes have been washed, the movable part of the top may be opened and the clothes removed from the tub and the water wrung therefrom.

In the bottom of the tub is arranged a drain tube 39 having therein a draw-off valve by means of which the water and sediment may be removed from the tub.

While I have shown and described the machine as having an air pumping mechanism arranged thereon and operated by the rubber actuating mechanism, it is obvious that I may connect the air conducting tube 28 with any suitable source of air supply or with a steam generating mechanism whereby steam may be forced through the clothes instead of air.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation. v

Various changes in the form, proportion and the minor details of construction may be resortedto without departing from the principle or sacrificing any ofthe advantages of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent is:

A washing machine comprising a tub, a clothes rubber operatively mounted in said tub, air conducting means opening into the tub beneath the clothes, and means for simultaneously actuating said rubber and supplying compressed air to said air conducting means.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
