HEATING DEVICE FOR WASHING MACHINES.

Application filed April 6,

To all 20 7mm it may concern Be it known that I, CHRIs M. DAM, a citizen of the United States, residing at Gordon, in the county of Sheridan and State of Nebraska, have invented new and useful Improvements in Heating Devices for Washing Machines, of which the following is a specification.

This invention relates to heating devices, particularly to attachments for washing machines, and has for its object the provision of a heating device adapted to be associated with the washing machine whereby to keep the water hot at all times so as to insure proper cleansing of clothes within the washing machine.

An important object is the provision of a heating device of this character which might be manufactured and sold as a separate entity to be attached to an already eX- isting washing machine or which might be built into washing machines during process of construction of the latter, the heating device including a boiler from which extends pipes connected with the washing machine and beneath which is located a suitable burner which might be an oil burner or the like.

An additional object is the provision of a heating device of this character which will be very simple and inexpensive in manufacture, highly etficient in use, durable in service and a general improvement in the art.

lVith the above and other objects and advantages in View, the invention consists in the details of construction to be hereinafter more fully described and claimed and illus trated in the accompanying drawings in which,

Figure 1 is a side elevation of a washing machine, equipped with my heater.

Figure 2 is a plan view.

Figure 3 is a front elevation.

Figure 4 is a longitudinal sectional view.

Referring more particularly to the draw ings the letter A designates a washing machine of conventional type which includes the usual receptacle B, ordinarily mounted upon suitable legs C. It is believed to be unnecessary to disclose all the mechanism of the washing machine and such is shown clearly diagrammatically in order that the application of my invention may be fully understood.

In carrying out my invention I provide a 1922. Serial No. 550,222.

heating device which includes a relatively small boiler 10 which is here shown as being rectangular in shape but which might just as well be some other shape it preferred. This boiler is located upon one side of the washing machine receptacle B and is preferably located immediately below the lowest portion of the washing machine and is held in place by means of a pair of inclined brace rods 11 which are secured at their upper ends to the receptacle B as by means of bolts 12 and which are secured to their lower ends to upstanding lugs 13 carried by the side of the boiler most remote from the washing machine. Leading from the top of this boiler 10 is a pipe 14 which leads into a block like member 15 which is secured upon one side of the washing machine, any suitable packing device being employed within this block member whereby to make a liquid-tight joint between the pipe 14: a hole 16 is formed in the side of the washing machine receptacle. It is of course to be noted that various different types of connections might be employed at this point and this detail is not material. Leading from the rear side of the boiler 10 is a pipe 17 which leads into the bottom of the washing machine receptacle through a hole 18 which is preferably covered by a perforated strip of metal, 19. Upon another side the boiler 10 is preferably provided with a drain cock 20 of ordinary pattern whereby the contents of the washing machine and boiler may be drained when necessary.

Associated with the boiler 10 is a suitable burner 21 which might be either a gas burner or an oil burner whichever might be found preferable. I have illustrated an oil burner of ordinary type which is suitably supported beneath the boiler 10-as indicated at 22 so that it will be maintained at the proper point with respect to the boiler to insure eflicient action.

In the use of my device it will be readily observed that the burner 21 will effectively heat the water within the boiler 10 and that the water thus heated will pass upwardly through the pipe 14: into the washing machine, the water returning through the pipe 17 into the boiler. In this way it will be readily apparent that there will be a constant circulation of hot water within the washing machine so that the washing action may be most efficiently carried out.

While I have shown and described the preferred embodiments of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangements of parts as Will not depart from the spirit of theinvention or the scope of the subjoined claim.

Having thus described my invention I claim:

The combination with the tub of a Washing machine of a boiler located below and to one side of the tub, a pipe connected With the lower portion of the end of the boiler adjacent the tub and connected With the bottom .of the tub, said pipe serving partially to support the boiler, brackets secured upon the end of the boiler most remote from the tub, inclined brace rods connected With said brackets and With the upper portion of the tub, a pipe rising from the top of the boiler and leading into the intermediate portion of the tub,'a shelf depending from the boiler and a burner mounted upon said shelf.

In testimony whereof I affix my signature.

CHRIS M. DAM.
