7 POWER WASHING-MACHINE.

Specification of Letters Patent.

Y Patented June 3,19t9.

Application filed December 22, 1917. Serial No. 208,461.

To all whom it may concern Be it known that we, HERMAN H. TOLL and FRANJ C. DUFF, citizens of the 'United States, and residents of Clarinda, in the county of Page and State of Iowa, have invented a new and Improved Power Washing-Machine, of which the following is a full clear, and exact description.

This invention relates to power washing machines, and hasto deal more particularly with a combined washing machine and centrifugal drier.

The invention has for its general objects to provide a machine'of this character which is reliable and eflicient in use, comparatively simple and inexpensive to manufacture and so-designedas to be easily manipulated for performing the double function of washing and wringing. Y

A more specific object of the invention is the provision of a cylinder having a con centrically arranged rotatable drum for containing the clothes and water, which cylinder is capable of being adjusted to a position with its axis horizontal, when the drum can be oscillated to perform the washing operation, and adjusted to a positionv with its axis vertical, when the drum canbe rotated at a high speed to perform the centrifugal drying or wringing operation, there being a novel driving mechanism whereby. the rum can be operated in either of the two. ositions.

' Sti another object of the invention is the provision of simple, novel and effective means for interchanging the washing fluids.

With such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto. v

In the accom anying drawings, which illustrate one em odiment of the invention and wherein similar characters of reference indicate corresponding parts inall the views,

Figure 1 is a front view of the machine with portions in section to illustrate the details of construction, the cylinder being disposed vertically and connected with the driving means for centrifugal drying;

Fig. 2 is a front view of the machine with the cylinder adjusted to horizontal position for the washing operation;

Fig. 3 is a horizontal section on the-line 3-3, Fig. 2;

Fig. dis an end View of the machine;

Fig. 5 is a detail sectional view on the line 55, Fig. 2; and

Fig. 6 is a plan view viewed from the line 6-6, Fig. 2.

Referring to the drawings, A designates a supporting frame of any approved character'which has at its top front and rear In the washer cylinder B is a perforated drum C in which the clothes to be laundried are placed, and this drum is mounted at one end on a rotatable stub shaft 7 and the opposite end is rotatably mounted by means of a journal 8 in a suitable bearin 9. The shaft 7 has a squared end 10 whic enters a correspondingly-sha ed socket 11 on the head or end 12 of t e drum. The cylinder has a cover 13 for the charging opening and the drum is also provided with a cover 14 through which the clothes are inserted or removed.

bearings 1 and 2 in which rotate the jour- Mounted at the bottom of the frame A the shaft 18 is seated in a follower 23 around which is disposed a spring 24 that is engaged by a lever 25 fulcrumed at 26 on the bottom of the frame and connected with an operating pedal 27 whereby the downward movement of the pedal 27 will transmit motion through the lever 25 and spring 24 and follower 23, so as to move the shaft 18 upwardly and connect with the shaft 7 when the cylinder B is in position to operate the drum C as a centrifugal drier, as shown in Fig. 1. The motor will thus rotate the drum C at a suitably high speed to cause the water to bethrown out of the clothes by centrifugal action, it being of course under stood that the washing fluid is drawn out of the cylinder B before the drum 0 is rotated. A belt tightcner 27 is operatively connected with the lever 25 so that after the shafts 18 and 7 are coupled, the belt 16 of the motor is tightened to transmit power to the shaft 18 after the coupling members 20 and 21 are engaged.

The motor D is connected by a gearing 28 with a horizontal shaft 29 which has on its left end, Fig. 3, a pinion 30 which meshes with a gear wheel 31 that has a crank pin 32 to which is connected the lower end of a pitman 33. The upper end of this pitman 33 has rack teeth 34 which are adapted to mesh with a pinion 35 on a short shaft 36 journaled in a bearing 37 at the top left portion of the frame, this shaft 36 having a non-circular socket or coupling member 38 which is adapted to engage with the circular coupling head 21 of the'cylinder B when the latter is adjusted to washing position, as shown in Fig. 2. The shaft 36 is moved longitudinally to couple and uncouple the parts, and when the parts are coupled the motor operates through the shaft 29, gearing 32 and 31, pitman- 33 and shaft 36 to oscillate the drum 0 for performing the washing operation. The rack bar or pitman 33 is adapted to be thrown into and out of operative position by means of a controlling lever 39 fulcrumed at its elbow on the frame A, and on the lever is a roller 41 which is adapted to form an anti-friction support for the upper end of the rack bar. By moving the lever in one direction the rack bar is disengaged from the pinion 35 and by moving the lever in the opposite direction these parts are engaged. The manipulation of the lever is employed to impart longitudinal movement to the shaft 36 to throw the same into and out of coupling position.

For this purpose a member 42 is connected with the shaft 36 and passes through a spiral slot 43 in a bearing bracket 44, and the member 42 is connected by a link 45 with the lever 39, and consequently the movement of the lever 39 will couple the shaft 36 with the drum C, and also connect the rack bar 33 with the pinion 35. Movement in the opposite direction will discone charge pipe 48 is connected with the pumpand leads upwardly at the rear of the machine, as shown in Figs. 2 and 4, and its upper end is connected with the cylinder B through the rear journal 4, which is hollow for this purpose. The pump is provided with a gear 49 which engages a pinion 50 on the shaft 29, and by means of a shifter 51 the pump can be operatively comlected with the shaft 29 through the pinion 50 and gear 49. The shifter 51 includes a rock shaft 52 which has a pedal 53 at its front end adjacent the pedal 27, so that the operator can easily throw the pump into and out of operation, as required. On one head of the cylinder B is a drain pipe 54 provided with a cook 55, which drain pipe can be directed to any tank for drawing off the fluid from the cylinder.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while-we have described the principle of operation, together with the machine which we now consider to be the best embodiment thereof, we desire to have it understood that the machine shown is merely illustrative and that such changes may be made when-desired as fall within the scope of the appended claims.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. A machine of the class described comprising a drum, a cylinder in which the drum is rotatably mounted, a rotatable shaft mounted to move vertically, clutch means between the drum and shaft, a controller adapted to be manipulated by an attendant, and spring means through which the controller acts to hold the shaft in clutching relation to the drum, whereby the shaft rotates the drum.

2. A machine of the class described comprising a supporting structure, a cylinder thereon, a drum in the cylinder to rotate on a vertical aXis, an upright rotatable shaft, clutch means between the drum and shaft, a follower supporting the lower end of the shaft, a pedal device mounted on the structure, and a yielding connection between the pedal device and follower, whereby the said device moves the shaft into and out of clutching relation to the drum.

3. A machine of the class described comprising a cylinder, a rotatable drum therein, :1 shaft movable axially, means between the shaft and drum for connecting and disconnecting them, a pulley on the shaft, a belt 10 operating the belt tightener.
