WASHII TG-MACHINE.
Specification of Letters Patent.
Application filed February 16, 1910. Serial No. 544,270.
To all whom it mag woman:
Be it known that I, FRITZ POHLMANN, engineer, a subject of the German Emperor, residing at 37 Streulistrasse, Zurich, Switzerland,.have invented certain new and useful Improvements in Washing-Machines, of which the .following is a specification.
This invention relates to a washing machine with double drums one inside the other, the .inner drum having hollow ribs through which the washing water is introduced under high pressure. The lIlIlOI' drum is free from holes and rough surfaces between the ribs and consequently the linen is not likely to get damaged and the holes in the ribs enable the water to flow freely and thus maintain a good circulation.
I will now describe my invention with reference to the accompanying drawings, in which Figure 1. is a side view partly in section of a machine constructed according to my invention. Fig. 2 is an end view of Fig. 1. Fig. 3 is a sectional view on line 33' of Fig. 1. Fig. 1 is a detailed. sectional view of the valved inlet apparatus discharging from the outer casing 1. Fig. 5, is a longitudinal section of the outer casing and drum. Fig. 6 is a transverse sectional view of the inner drum. Fi 7 is a view similar to Fig. 5 of a modified form of the invention. Fig. 8 is a transverse section of the form shown in Fig. 7. Fig. 9 is a View similar to Fig. 7 showing a further modification. Figs. 10 and 11 illustrate an improved float controlling device.
The washing machine-shown in Figs. 1 to 6 shows an outer-drum mounted on pillars 2 inside which a rotatable inner drum 3 is arran ed, the said inner drum being rotated in ependently of the outer drum. The inner drum is arranged with a hollow shaft 4 connected by pipe 5 with the water under pressure, the said pipe leading from two water tanks, 6, 7, and having in it a force pump 8. The tanks 6, 7 are placed close to the outer drum 1 and two discharge pipes 10 lead from the drum to the inlets 11 of the tanks. Each of these inlets is encircled b a ring 9 of tight fittin material on which the end of the pipes t and to insure this close fitting a pivoted loop 12 is arranged to engage lugs or pivots 13 fixed to the pipe in such a manner as to draw the pipe closely down on to the ring 9 of the material. Each pipe is provided with a throttle valve 14. The inner drum 3 has a chamber 3 at each end formed by the main walls 15 connected with the hollow shaft 4 and the casing 16 which is provided on the inside with hollow axial ribs 17 each arranged about a pipe 18 leading to the two chambers. The ribs 17 and the pipes 18 are provided with bores or outlets 19 of equal size and which coincide so that water may be injected from the chambers through the pipes 18 and into the inner drum. The
The tanks 6 and 7 are connected to the pipe 5 by valves 21 and the tank 7 is designed to hold water for rinsing purposes water escapes, the said collector automatically taking away the dirt floating on the surface. 1
The method of washing may be described as follows: By means of the pump, lye can be drawn from the tank 6 and forced through the hollow shaft into the chambers of the inner drum and from there to the pipes 18 from which it passes in jet-like manner on to the linen in the inner drum and after passing through the clothes. escapes from the inner drum by the openings 20 and returns therefrom to the tank 6. During this process the tank 7 is closed and the washing lye may be circulated through the machine as long as desired: By adjustingthe valves, rinsin water may be drawn from the tank 7 an used inthe washing or the whole rocess of washing carried out by closing the admission and discharge filled.
For the-purpose of emptying the drums the arrangement as shown in Figs. 1 and a may be employed. This arrangement conpipes after the Idrumshave been partially sists of a neck-25 provided with an adjustable valve 26 which is held by spring p'ressure. A discharge pipe 29 having an inlet .30 is arranged in the pillar 2 and. adapted to meet theneck 25, the said pipe having a v spring controlled rod 31 capable of being moved against the valve 26 and opening it, the said rod being held out of engagement by a spring 32.
Figs. 7 and 8 show a drum with a central perforated partition 40 dividing the drum into two chambers, the end walls 42 and 43 of which are perforated. The water enters the chambers as indicated by the arrows. Some of the pipes in this modification are without outlet holes to the ribs for the purpose of conveying water to the farther chamber before distribution. -Fig. 9 shows three inner chambers the walls of which are perforated and in this case water is introduced at each end of the drums This arrangement provides means whereby soiled linen maybe graded and placed within the chambers according to the activity of the flow of washing material. v
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be per-v formed I declare that what I claim is:
1. A washing machine comprising in comblnatlon, an outer casmg, a revolubly mounted casing disposed 1n sald outer casing and provided with inwardly projecting ribs opening outwardly and having inlet openings therein, pipes disposed in said ribs and having openings communicating with said inlet openings, the walls of said ribs having outlet apertures opening to said outer casing, and means for continuously supplying water to said pipes.
2. A washing machine comprising in combination, an outer casing, a revolubly mounted casing disposed in said outer casing and having inwardly projecting ribs provided with inlet apertures, pipes disposed in said ribs and revolving with said inner casing and having openings communicating with saidinlet apertures, the walls of said ribs having outlet apertures disposed radially outwardly with respect to said inlet apertures, said inner casing being imperforate and continuouslysmooth between said ribs, and means for continuously supplying water to said pipes.
In testimon whereof I aflix my signature in presence 6 two witnesses.
