HERMAN WEBER, OF CHICAGO, ILLINOIS.

DUMPING PAN FOR Application filed January To all whom it may concern:

Be it known that I, HERMAN WEBER, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Dumping Pans for Laundry Machines, of which the following is a specification.

My invention relates to dumping pans for laundry machines and it has for its principal object the provision of a new and improved arrangement of parts by which a predetermined amount of water may be readily measured out and held in readiness for use for the succeeding operation of the machine to which the device is applied, whereby such accurately measured charge of water can be fed quickly and easily to the machine.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Fig. 1 is a view of my improved apparatus as applied to a washing machine;

Fig. 2 is a vertical cross section, through my improved apparatus, being taken substantially on line 22 of Fig. 1;

Fig. 3 is a fragmentary view, being a ver tical section taken through my improved dumping pan structure at one side thereof;

Fig. 4 is a cross section taken on line 44 of Fig. 3;

Fig. 5 is a cross section similar to Fig. 4 but showing the condition of the valve when the pan is turned into dumping position;

Fig. 6 is a face view of one of the rack bars by which the position of the pan is controlled; and

Fig. 7 is an edge view of the parts shown in Fig. 6 as seen from the left in that figure.

Referring to the several figures of the drawings, 10 indicates the body of a washing machine of any approved type, supported by standards 11 at its ends. An open-ended tank 12 is mounted at one side of the machine 10 in position to extend a short distance above the machine, being supported in position by any suitable means. The tank 12 is open at its lower end portion, being in communication with the interior of the body of the washing machine through- LAUNDRY MACHINES.

out the full length of the tank, as is indicated by dotted lines in Fig. 1, the arrange ment being such that the tank is'adapted to be emptied in a very short time when a quantity of water is placed therein.

Within the tank 12, and adjustable vertically with respect thereto, I have provided a receptacle or pan 13, which also isopen along its top portion. For the purpose of providing that the pan 13 may be emptied very quickly into the tank 12, I have mounted the panv revolubly in position so as to be turned in clockwise direction in Fig. 1. For

providing means for feeding water to the pan 13 in its various adjusted positions vertically, and for taking care of the vertical movement of the pan with respect to the tank 12 and for the pivotal movement of the pan about its longitudinal axis, I have provided pivotal mounting means comprising a sleeve 14 fixedly mounted upon the pan 13 at one end, such pivotal mounting means being revolubly mounted within slide blocks 15 which are movable vertically in slots 16 provided in the end of the tank 12. In the construction shown, the pivotal mounting member at the end of the pan opposite that at which the sleeve 14 is mounted, is also in the form of a sleeve which is indicated by 17 the inner end of the sleeve 17 being closed by a plug 18 of any suitable type. Handles 19 of any approved form are fixedly mounted upon the outer ends of the sleeves 14 and 17 for turning the pan 13 about its pivotal axis within the tank 12.

For controlling the position of the slide 7 blocks 15, I have provided rack bars 20 which in the construction shown are formed integrally with the slide blocks. A longitudinally extending shaft 21 is journalled in the ends of the tank 12, being provided with segmental gears 22 upon its ends, meshing with the rack bars 20. The shaft 21 is provided with a handle 23 fixedly mounted thereon at one end for turning the shaft 21 for effecting a vertical movement of the rack bars 20 with the slide blocks 15 and the pan 13 carried thereby. For holding the pan 13 in the desired elevated position, I have provided a pawl 24 pivotally mounted upon a bracket 25 carried by the end of the tank 12, such pawl being adapted by engagement with a segmental ratchet 26 to prevent rotation of the shaft 21 in clockwise direction movement of the pan 13 within the tank.

For delivering water to the pan 13, I have provided a pipe 27 extending into and through the sleeve 14; into position within the pan 13, the end ofthe sleeve 1 1 about the inner end of the pipe 27 being enclosed by means of a cap 28. The pipe 27 is designed to have a close working fit within the sleeve 14 and the cap 28 so as to normally prevent the escape of 'water between such parts, communication being provided between the pipe 27 and the interior of the pan 13 by means of ports 29 and 30 in the walls of the pipe 27 and the cap 28, as is best shown in Fig. 1, such ports being in registering position when the pan 13 is in its normal upright position. hen the pan 13 is turned in clockwise direction in Fig. 1 for dumping the contents of the pan into the tank 12, the port 30 is turned out of registry with the port 29 into approximately the position shown in Fig. 5, whereby the delivery of water through the pipe 27 to the pan 13 is prevented, this result being attained automatically upon the operation of giving the pan 13 an operative rocking movement for dumping its contents. As is indicated by dotted lines in Fig. 2, the inner end of the pipe 27 is preferably closed by the plug 31.

The means provided for delivering water to the tank 13 through the pipe 27 com prises two short pieces of pipe 32 and 33 which have a rotatable connection with the pipe 27 and with the pipe 3 1 respectively, the pipe sections 32 and 33 being also pivotally connected together, this construction be ing provided for the vertical movement of the pipe 27 with the pan 13.

Water is fed under pressure to the pipe 34 by means of pipes 35 and 36 leading from tanks 37 and 38 respectively supported in position opposite the tank 12, valves 39 of any approved type being interposed in the pipes 35 and 36 for controlling the admission of water therethrough. The tanks 37 and 38 are designed to contain hot water and cold water respectively, being fed through pipes 40 provided with valves4l-1 which are controlled by balls 42 of any approved type for maintaining the level of water in the tanks 37 and 38 at the desired height. Overflow pipes 43 are provided for taking care of any possible excess of water within the tanks.

As is clearly shown in Fig. 1, the tanks 37 and 38 are positioned with respect to the tank 12 so that the level of the water as controlled by the float valves ll is maintained at a point corresponding substantially to the position of the sleeve 14 when moved to the limit of its upward movement as is shown in Fig. 1. By this arrangement, as is indicated by the dotted line representing the level of the water in said figure, when the valves 39 are opened, the water will be of comparatively small depth in the pan 13 when the pan is in its uppermost position, and will be of correspondingly greater depth when the pan is lowered through the medium of the handle23 and its co-operating parts. With the valves 39 opened more or less completely so as to give the desired ratio of flow through the pipes 35 and 36, the temperature the quantity of water of the desired temperature and of the predetermined desired amount is maintained at hand adjacent to the machine 10 ready for prompt and speedy delivery to the machine 10. In operation, the operator will set the handle 23 at the desired point for placing the pan 13 in position for receiving the amount of water which will be required for the next succeeding operation of the machine. Even though comparatively small pipes be provided between the tanks 37 and 38 and the pan '13, the desired amount of properly tempered water is assured ready for use at the desired moment, inasmuch as the pan 13 is adapted to fill slowly during one washing operation for use during the next operation. By providing for an accurate measuring of the water for use in the machine, a very great saving is effected in the amount of soap required. As will be readily appreciated, soap must be added to bring about the desired condition of the water, even though an excess of the water he used, and by the use of my improved apparatus by which the amount of water is very readily and easily measured and controlled, a saving of soap and fuel is very easily effected.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
