I have here shown this invention as embodied in, or applied to, a conventional type of laundry washing machine including a cylindrical outer casing and a clothes container or drum mounted to rotate about a horizontal axis in the casing, the casing having peripheral loading and unloading doors, and the drum also having similar doors which are brought into register With the doors of the casing to load and unload the articles into and out of the drum. The attachment may, however, be applied to other types of machines. For brevity and convenience,v the term water is used in referring to thle Washing uid. It will be understood that the term waten,M

comprehends other fluids, solvents, etc.

I designates the outer cylindrical casing suitably supported on bases' 2. 3 designates the inner article container or washing drum. 4 designates the loading and unloading doors. The drum 3 has similar doors not shown arranged to be brought into register with the doors l.

The container 3 may be actuated in any Well known manner. 5 designates a feed conduit through which the Water is filled into the washing machine or the casing I and the drum 3. The conduit is connected to any suitable source of supply, and as here shown is connected through a header 6 to pipes 1 and 8 leading to separate sources of hot and cold'water. The flow through the pipes I and 8 into the conduit 5 is controlled by valves located in the header 6. These valves are usually automatically operated and their operation controlled by a timer.

9 and I0 designate respectively outer casings of fluid motors for opening the valve controlled pipes 1 and 8, which valves are self-closing. The movable member of these fluid operated motors is usually a diaphragm, and the casings 9, YIl! are diaphragm chambers. The pressure sides of the chambers are connected to a source of compressed air through pipes Il, I2 respectively. The opening and closing of the valves is controlled by a cycle timer. As .the timed and automatic Voperation of a washing machine is Well known, and form no part of this invention, further description of the valve operating and timing means therefor is though to be unnecessary. Valves in other pipes and conduits are similarly operated and timed, as will hereinafter appear.

All washing machines, regardless of their types.

each of the pipes 20 is controlled by a timer operhave a feed conduit or conduit for conducting the water to the washing machine, a dump valve, as I3, for emptying the machine of the washing fluid.

The agent supplying attachment constitutes 5 the subject matter of this invention and comprises a receptacle for the agent, a pipe communicating with the receptacle and with the conduit 5, and a passage leading from the receptacle to the machine, and preferably communicatinglwith the machine or casing I through the conduit 5. The pipe conducting water to the receptacle opens into the bottom portion, so that the incoming Water or uid mixes with the agent in the receptacle and the mixture overflows from the receptacle at the top thereof into the passage that discharges into the washing machine or the casing I thereof.

A complete laundry washing operation comprises one or more treatments with water at various temperatures including a solvent or a soap, one or more rinsing operations during some of which other agents, as bleach, sour, etc., are added. Also, the washing operations may include treating the articles being washed with various chemicals. This attachment therefore comprises a plurality of receptacles for the various ingredients. The attachment comprises a tank I4, a plurality of receptacles I5 therein, thel tank being in the form of a box or trough. The receptacles I5 are located along one side wall of the tank and spaced apart from the other side wall and also spaced apart from the bottom of the container providing a passage or manifold I6 common to all of the receptacles, the recepy tacles opening at their tops at I1 into the tank to permit the overflow of agents or ingredients mixed with water into the tank, that is, the passage I6. The tank is coupled into or communicates with the conduit 5 to receive the water therefrom and also discharges into the machine or casing I thereof. The tank is therefore a portion or section of the feed conduit 5.

In the machine here illustrated, the tank is located along the front side of the casing beneath the doors 4, this being the place in this type of Washing machine where the agents or ingredients are usually fed by hand into the washing machine of this type. In other types, the receptacles or the container may be otherwise 50 located. The tank I4 also has a suitable cover I6 at its top, which, when open, gives access to the receptacles to supply the ingredients thereto. The tank discharges at its opposite ends into the casing I through sections 5a, the bottom Wall of the tank preferably sloping from its intermediate portion toward its ends. In order to prevent surging of the water through the pipes 5* into the tank I4, a suitable valve, as a flapper valve I9, is'provided at the 'inner ends of` the conduit sections 5e.

Each of the receptacles I5 is connected by its own individual pipe 20 to the intake conduit, and

ated valve. 2l designates the diaphragm cham bers of these valves, said chambers being similar to the diaphragm chambers 9, I having pipes 22 leading to a. suitable source of compressed air, the pipes 22 being controlled by timer operated valves. As here shown. the pipes 2li communicate with the feedv conduit through a header 23, which is connected to the header 6, and a timer operatedcontrol valve, similar to the valves 9, I0 may be provided for controlling the flow of fluid into the headerl. 24 designates the 75 casing of the diaphragm chamber operating this valve.

The conduit 5 is shown as provided with a?.v

valve 25 operable into one position to permit the flow of water through the conduit 5 and into the washing machine through the tank I4, as; just described, and into another position to permit the water to enter directly into the washing machine through a branch conduit 26 without passing through the tank I4. When the water is being filled into the machine through the branch 26, a portion of it may also be passed or shunted through the header 23 and pipe 20 to the agent receptacles I5. Thus, the machine l5 may be operated by passing all the water into the machine through the tank I4 or by operating the valve 25 into its second position just described. By flliing the Water directly into the washing machine through the branch pipe 26,

and a part only thereof lay-passed through the agent receptacles and the container I4, the valve controlled by the diaphragm chamber 24 is opened by the timer, and any valve in any one of v the pipes 20 is open. The pipes 20 open into the lower portion or through the bottom of the receptacles I5 respectively. Also, a suitable manually operable dump valve 21 is provided for each receptacle, this dump valve being accessible for manual operation, when the cover I8 is open.

30 Instead of a dump valve 21, a siphon pipe 3| (Figure 4) may be used to empty the residue that would otherwise remain in the receptacle. When the water starts filling into or flowing through the receptacle, it also rises in the inner leg of\ the siphon and the level of the water rises above the bend in the siphon. The siphon will begin:i to operate and continue to operate until substan` tially all the water is siphonedout of the receptacle I4. The lower end of the inner leg of the siphon is located in a Well 3|a in the bottom of the receptacle. The washing machine is also provided with suitable control devices for controlling the temperatures of the water.

In the form shown in Figure 1, the receptacles are formed with perforated, foraminous or mesh diaphragms 28 spaced apart from the bottoms thereof on which the agent, if granular or powdered, rests so that the incoming water passes up through the mesh.

In the form shown in Figures 5 and 6, the receptacle is provided with a perforated stand-pipe or tower 29 spaced apart from the side walls of the receptacle and through the bottom of which the waterpipe 20 communicates with the interior of the stand-pipe or tower. When the pipe 20 is open, the water enters the tower, passes laterally out of the perforations thereof and thoroughly mixes with the agents or ingredients, particularly when the. ingredient is granular or a powder.

In the embodiment of the invention shown in Figure 1, the header 23 is shown as adjacent the intake pipe conduit 5 at one end of the casing E.

In Figures 4 and 7, a header 230 is shown differently located, or as located adjacent the ends of the tank I4 and communicating with the pipe or conduit, or the header 6 thereof, through a pipe 30.

.Owing to the unitary character of the container and the receptacle I5, an agent supplying attachment can be readily applied to or built into a washing machine without modifying the structure of the washing machine itself, as the attachment is applied to the machine by connecting mg operation. When the water is free to flow tion of the tank II and distributes throughout the length of the tank Il and discharges through the conduit sections 5 into the washing machine. Also, the water passes from the header 23 into any one of the pipes 20, the valve in which is open, to the bottom of the corresponding receptacle I5 and flows upwardly through the same, picking up and mixing with the agents or ingredients therein, which mixture overflows at I1 into the passage I6 of the tank I 4 and passes with the main stream of water coming through the conduit 5 into the Washing machine through the conduit sections 5a. The ow upwardly through the receptacles` continues during the entire filling operation and the agents or ingredients are thoroughly washed out of the receptacle and mixed with the water before the washing machine or casing I is nlled to its predetermined level. Hence, the receptacles are free of any liquid mixture during the latter period of the nlling operation of the machine or casing I. When the receptacles are being refilled for the next operation, any water .rrernaining in the receptacle may be drained out by opening the valve 21 by hand preliminary to placing the ingredients therein.
