HANS C. HOTING, OF CHICAGO, ILLINOIS, ASSIGNOR T TROY LAUNDRY MACHINERY C0., LTD., 0F CHICAGO, ILLINOIS, A CORPORATION OF NEW YORK.
COMBINED WASHER AND DRIER.
Application iled April 7, 1919. Serial No. 288,112.
10 all wim/n it may concern.'
Be it known that I, HANS C. Ho'riNG, a citizen of the United States, residinfr at Chicago, in the county of Cook and gtate of Illinois, have invented certain new and useful Improvements in Combined IVashers and Driers, of which the following is a specification.
This invention relates to a combined washer and drier.
Laundries as run today are provided with washing machines, extractors for extracting some of the water from the washed goods, and drying machines. These separate machines for performing their particular functions, when considered collectively, among other things, cost considerable money, occupy considerable space, and require much handling and moving of the goods.
Accordingly, one object of my invention is to overcome the objections hereinabove Set forth and to provide a .single machine in which clothes-may be washed, thoroughly rinsed, dried and cooled before being removed from the machine. l
Another object is to provide a combined washer and drier of relatively large capacity, occupying a minimum amount of space and adapted to meet all of the requirements of successful commercial use.
A still further object is to'provide a washing machine, together with a spraying system, through which iiuids of various kinds may be delivered against the clothes being treated so that the action of the uids may have a cleansing action on the clothes.
These and other objects are accomplished by means of the mechanism shown on the accompanying sheets of drawings, in which- Figure 1 is a side elevation of a' laundry equipment including three of my combined washers and driers; I
Figure 2 is a plan view of the same laun- Figure 3 is a plan View, on an enlarged scale, of one of the washers and driers, together with auxiliary apparatus;
Figure 4 is an end view of one of the washer and drier units, showing driving .mechanism therefor;
Figure 5 is a longitudinal vertical sectional view of one of my combined washers and driers; f
Figure 6 is a transverse sectional view of the same'combined washer and drier. showing associated auxiliary apparatus in side elevation;
Figure 7 is another transverse sectional view of one of the units showing one end of the rotary member in elevation;
Figure 8 is an enlarged detail view of a portion of a partition between two adjacent compartments of the rotary member shown in Figure 6; and
Figure 9. is a detail sectional view of a portion of the partition between adjacent compartments of the rotary member, showing a pipe provided with apertures through which washing and rinsing water is passed.
The various novel features of my invention will be apparent from the following description and drawings, and will be particularly pointed out in the appended claims.
Referring first to Figures 1 and 2 of the drawings, it will be noted that I have shown a laundry equipment including three of my combined washers and driers l0', which are supplied with cold water from a cold water supply tank 11, the cold water being fed through a feeder pipe 12, from which branches 13 and 14 extend to each machine. Hot Water is supplied to each of the combined units from a hot water supply tank 15, which supplies hot water to a feeder pipe 16 from which branches 17 lead to each of the combined units. Each of the branches 13 and 17 is provided with a. valve 18, by means of which the temperature of the water passing through the connecting pipe 19 may be controlled, said connecting pipe 19 leading to the base 20, preferably of concrete, of each machine. The connecting pipe 19, in each case, likewise is provided with a valve 21. Each of the branch pipes 14 is provided with a valve 22 for controlling the supply of cold rinsing water to each of the units 10. As sta-ted above. not only are the clothes washed and rinsed in each of the units 10, but the clothes are dried and cooled in. each of said units before being withdrawn therefrom. In this connection I have shown the boiler room 23 having boilers 24 provided with a common smoke-stack 25, in the enlarged portion of which is an air economizer 26, connected to the pipes of which is a fan 27 for drawing air from the outside through a pipe 28, forcing same through the economizer 26 and through a main feed pipe 29 and through branch pipes 30 into each machine, as will be pointed out kmore particularly hereinafter.
Referring now to the other figures of the drawings, it will be noted that each one of the combined washer and drier units 1ncludes an outer stationary casing 31, which is mounted in the concrete base 20, into the bottom lof which the combined hot and cold washing water is led through the pipe 19. This base is provided with an inclined exit opening 32, through which the water may pass into a pit 33 in which is mounted a centrifugal pump 34 directly connected to and driven by an electric motor 35 mounted on a cover 36 over the pit 33. The pump 34 is provided with a supply pipe 37, which is connected to and feeds a pipe 38 (see lFigures 2, 3 and 4), which joins its asso-v ciated cold water rinsing pipe 14 in a common pipe 39 (see Figure 5), which extends through a journal 40 at one end of the rotary] member 41 of the combined washer and drier. The operation and functions of the parts will be referred to more in particular hereinafter.
The rotary member 41 of the combined washer and drier includes a central hollow shaft 42, upon which are mounted end heads 43 and 44, the outer ends of which are provided with journals 45 and 40 respectively, which are mounted in bearings 46 of the base 20. The rotary member 41 preferably is hexagonal in shape, each of the six sides being in the form of wire mesh 47, said wire mesh spanning the distance between the end heads 43 and 44 and being supported by suitable frame members. T he rotary member 41 preferably is divided into three compartments by three longitudinally and radially extending partitions 48, the inner ends of which are formed by a spider-like construction having a hub portion 49 surrounding the shaft 42 and having hollow arms 50 (see Figure 9), the outer ends of which are closed by plates 51 for a purpose to be referred to hereinafter. The outer portion of each of these partitions 48 comgrises spaced screens 51 occurring in pairs.
etween the screens 51 (see Figure 8) of each pair there are mounted a plurality of funnels 52 and 53, which are held in position by spacers' 54 and a bolt 55 passing therethrough. These funnel members 52 which occupy the outer extreme portion of the partitions 48, not only permit the passage of water from one compartment to the other, but give the water a jet-like action for forcing the waterfthrough the goods with greater force for cleaning and rinsing purposes, the funnels 52 being particularly effective when the rotary member is rotated in one direction and the other funnel mem-` hers 53 being particularly effective when v the rotary member is rotated in the opposite direction,
Mounted within the rotary member 41 are a plurality of pipes 56 supported within pockets 57, said pipes 56 extending longitudinally between the end heads 43 and 44, it being noted that the end head 44 is provided with a plurality of passageways 5S which communicate with the pipes 56 located near the periphery of the rotary member, said passageways in the head 44 being in direct communication with the water supi ply pipe 39. Mounted within the partitions 48, and particularly in the middle part of each of said partitions, is another water pipe 59, which is properly supported between the plates 51' and 60, a-nd which pipes 59 extend between the end heads 43 and 44, said pipes 59 being in open communication with passageways 61 in the end head 44, which passageways are in direct communication with the water supply connection 39.
Each of the water pipes 56 is provided with a longitudinally extending series of apertures 62 for directing a stream of water radially inwardly toward the shaft 42 and toward the center of its particular associated compartment. Each of the Water pipes 59 is provided with two series of longitudinally extending apertures 63 and 64, the apertures 63 directing streams of water toward the center of its associated compartment and the other series of apertures 64 likewise directing streams of water to the center of its associated compartment.
As a result thereof, these six perforated pipes 56 and 59 direct three streams of water toward each other in substantially a. 180 relationship toward substantially the center of each of the three compartments of the rotary washing and drying device. In this/"way aV better washing and rinsing action is made possible.
It will be understood that during theV washing, rinsing, drying and cooling operations, the rotary member 41 will be actuated. For this purpose, an electric motor 65 is provided for each unit, said rotary member 41 being driven by said motor through s train of gearing 66, to be described in greater detail in another application; said train of gearing including a rocker arm 67 (see Figure 4) 1yieldably connected to a. toothed segment 68 meshing with av gear 69 'mounted on the samev shaft with a relatively large gear 70 meshing with an idler gear 71, which in turn meshesv with a gear 72 mounted upon the journal 40.
In the operation of this system, water of the proper temperature in the first instance is supplied in each case to the base 2O through the pipe 19, the water gradually rising in the base 2() and in the associated pit 33 until the desired level of the water shown has been reached, whereupon the water maybe turned oil either automatically or manually by means of the valves 18 and A 21. As the water'is supplied to the base 20 and pit 33 and approaches its predetermined height, it causes a float 73 (see Figure 6) to rise, said 'fioat being operatively connected to a chain 74 (see Figure 5) which passes over sheaves 75, and to the free end of which chain a Weight 76 is connected, said chain 75 being provided with collars 77 for operating the handle 78 of an electric controller 79 for controlling the electric motor 35 which is connected to and drives its associated water pump 34. Let it be assumed that each compartment of the rotary clothes,
`of the rotary member 41, and that the rotary container 41 has been set into operation, and that the washing water has reached its predetermined level in the base and the pit 33, whereupon the. motor 35 is automatically set into operation through' the movement of the float 73 and the effect of weight 76. The centrifugal pump therefor, being driven by the .motor 35, draws Water from the pit 33 and forces the water through the pipes 37, 38 and 39, through the passageways 58 and 61 in the end head 44 into pipes 56V and 59 and out through the apertures 62, 63 and 64, from which the water squirts in a jet-like manner, as shown in Figure 6 of the drawings, these jets or streams of water playing upon the clothes being washed; it being understood that the washing water is provided with the suitable amount of soap.
As the jets of water are playing upon the clothes being washed, the rotary member 41 is given a rotary action, preferably a certain number of revolutions in one direction and then a certain number of revolutions in another direction. As the rotary member is rotated, the clothes, in addition to being worked-on by the jets of water, fall from an elevated position down into the corners of the diagonal-shaped compartments, causing a compressive action to be given to the clothes being washed; it being noted also that the lower corners of the diagonalshaped compartments are under water at the l time and that jets of water passing through of the pit 33, cold rinsing water is supplied through the branch pipes 14 by proper ration ofthe valves 22 in said pipes, t e cold rinsing water passing through the pipe 39, passageways 58 and 61 1n the head 44, and through the same' system of pipes 56 and 59' from which the rinsing water passes through the apertures 62, 63 and 64 for thoroughly rinsmg the washed clothes, it being understood that 'the drain valve is :maintained in an open position to permit the rinsing water to drain off. During this rinsing operation, the rotary member 41 is maintained in operation 'and continued in operation any desired length of time, the rinsing operation also being continued the desired length of time. In
connection with the supply of rinsing, water through the pipes 14 and 39, the pipe 38,
through which the washing water is pumped is provided with a check valve 84 for pre? venting the rinsing Water escaping toward the pump 34. After the goods are thoroughly rinsed, they are dried.
In connection with the drying operation, air, preferably at .180 Fahrenheit under a two-ounce pressure, is supplied by the blower 27 through the economizer 26, feed pipe 29 and branch pipes 30 (see Figures 1 and 2). Referring now to Figure 5', it will be noted .that the branch 30 in each case is provided with a valve 85 for controlling the supply of the hot air through the hollow journal 45 which is in open communication with the hollow shaft 42. (see Figures 5 and 6) is provided with a plurality of. series of apertures 86 registering with corresponding apertures 87 in the spider hub 49, whereby hot air is shot radially outward 'from the hollow shaft -42 to play upon the washed and rinsed clothes. After a predetermined length of time, it being understood that the `rotary member 41 is in operation, the clothes will become dry not only as a result of the hot air jets playing upon the wet clothes, but alsol as a. result, especially in the first part of the drying action, of the clothes fallingv down into the wedge-like corners of each compartment, causing a naturalwedging or squeezing action upon the clothes for forcing some of the Water therefrom.
After a predetermined length of time, the goods will be completely dried. Not only is the hot drying air forced into the compartment of the rotary member or container 41 under pressure, -but the moisture laden air is drawn out of the casing 31 through an eX- haust 87 in the upper end of the casing by a suction action created by a ,motor driven centrifugal pump 88 which is connected to each of the exhaust pipes 87 by a. pipe 89 common to all, said moisture laden airbeing forced into a cyclone 90, from which it passes into the atmosphere through a pipe 91, the lint in the moisture laden air being deposited in the cyclone 90 and'therefore prevented This hollow shaft from passing outwardly through pipe 91. The exhaust pi e 87 in each case is pro` vided with a va. ve 92 mounted in said pipe.
After the goods have been dried by the hot air, the supply of hot air is shut olf. However, the dried clothes atI this time are too hot to handle. Accordingly, I have provided means for cooling the clothes before they are Withdrawnv from the machine. In this connection it will be noted that the base of the machine is provided with a ventilator 93, which may be in the form of a shutter arrangement, cold air being drawn through the ventilator 93 through the dried clothes and out through the exhaust pipe '87, through which a suctionv extends as a result of the suction pump 88, the valve 92 at this time being opened and the valve 85 in pipe being closed. When the dry clothes are suiiiciently cooled, the rotary container may be stopped and the cleansed and dried clothes removed.
By means of this combined machine, the clothes not only are thoroughly washed, rinsed, dried and cooled in a single unit, but at the same time this single combined unit is eflicient in its operation and occupies a minimum amount of space.
There may be various modifications of the invention herein shown and described, and it is my intention to cover all such 1nodifications which do not depart from the spirit and scope of the invention as set forth in the following claims.
