APPARATUS FOR WASHING CLOTHES.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed July 5, 1907. Serial No. 382,354.

To all whom it may concern:

Be it known that I, MANUEL J. BAKER, of the city of Buffalo, in the .State of New York, United States of America, have invented certain new and useful Improvements in Apparatus for Washing Clothes, of which the following is a specification.

My object is to devise simple and-cheap means for use in Washing clothes which will enable the rubbing board to be dispensed with, and which will do its work effectively with a minimum of labor.

The device comprises a cylinder within which is fitted a water tight piston operated by a rod passing up through a tube connected to the top of the cylinder. A spring is provided tending to raise the piston, and the lower edge of the piston is provided with an annular flan e which answers the double purpose of stifl ening the cylinder and of preventing it bedding itself too deeply in the clothes.

Figure 1 is a view in elevation of my improved clothes washing device. Fig. 2 is a vertical section of the same. Fig. 3 is a plan view of the device showing corrugations in the annular flange thereof. Fig. 4 is a side elevation of part of the cylinder showing a corrugated flange. Fig. 5 is a plan view of a preferred form of bottom flange, shown in section in Fig. 2.

In the drawings like letters of reference indicate corresponding parts in the different figures. 4

A is a cylinder open at its lower end. In its upper end is formed an opening communicating with a guide tube B secured to,

the top. Through this guide tube slides a piston rod or handle C. To the lower end of this handle is secured the piston D.

As it is my object to make a machine which can be constructed as cheaply as possible, exact fitting of the cylinder and piston is not easily obtained. By means of the construction shown I am, however, enabled to secure as close a fit as is necessary for eflicient action.

The piston comprises two plates a, b, between which is fitted a disk of felt or leather 0. The upper plate a is closely fitted to the cylinder while the plate I) is of somewhat less diameter. The edge of the felt is thus permitted to turn up in a flange, as shown, forming a sort of shallow cup-shaped piston.

The pressure of the fluid on the down stroke of the piston tends to press the edges of the felt into contact with the cylinder, making substantially a water tight fit. The piston is normally pressed upward by spring pres sure. For this purpose I employ an external and an internal spring though I do not restrict myself to the use of two. Externally a coil spring E may be placed about the guide tube B bearing against the top of the cylinder. This guide tube is preferably provided with slots 0 for the passage of a pin F passing through the handle and engaging the upper end of the spring. Internally I employ a tapered coil spring Gr having its upper end bearing against the under side of the piston and its lower end engaging a suitable ledge formed on the inner side of the cylinder at its lower end. In practice I form this ledge by securing to the lower end of the cylinder an annular flange H which extends both outwardly and inwardly of the wall of the cylinder. This flange prevents the cylinder sinking into the clothes in such a manner as to seal up the mouth of the cylinder and prevent water being forced from the cylinder through and among the clothes. It also provides an engagement for the coil spring, as hereinbefore referred to. To facilitate the exit of water from the cylinder the flange may be corrugated, as shown in Figs. 2, 3 and 4.

The operation of the device is as follows The clothes having been properly soaked and placed in a suitable tub, with the necessary soap and water, the apparatus is pressed down upon the clothes and the handle rapidly operated to force a stream of hot soapy water back and forth through and among the clothes. The clothes are of course repeatedly turned about and the instrument applied to different parts until the whole has been effectively cleansed.

This apparatus will be found not only to be cheap but also effective in operation, and not liable to get out of order.

The preferable method of forming the bottom of the device is as shown in Figs. 2 and 5, in which the open middle space is crossed .by the cross bars as and 1, with openings around the flange e, and corrugations e, as indicated, leading up to the holes from the middle opening. WVhen the bottom is made in this manner better suction is obtained, and quicker action can be obtained when working the pump.

WVhat I claim as my invention is: V p 1. In apparatus of the class described the combination of a cylinder open at one end; a piston working therein; a handle secured to the piston; a spring tending to raise the piston; an outwardly extending annular flange formed at the lower edge of the cylinder with a series of openings formed therein; and corrugations between each of the openings in the flange and the inner opening.
