WASHBOILER.

SPECIFICATION forming part of Letters Patent No. 737,763, dated September 1, 1903. Application led September 80,1902. `Serial No. 125,404. (No model.)

To @ZZ whom, it may concern:

Be it known that I, ALEXANDER McLnoD, gardener, of the town of New Glasgow, in the county of Picton, in the Province of Nova Scotia, Canada, have invented certain new and useful Improvements in Washboilers; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to improvements in washboilers; and the objects of my invention are to devise a cheap, simple, and easily-inanpulated boiler in which clothing or other fabric may be thoroughly cleansed without the wear necessitated by the use of washboards or other frictional washing-machines; and it consists, essentially, of a vessel of suitable form having a false bottom and perforated cover, said cover extending down into the vessel below the upper edges thereof, and means being provided for enabling the boiling water to circulate from beneath the false bottom to above the said perforated cover and back again underneath the false bottom, thus continually circulating through clothing or any fabric or other material which has been placed in the boiler to be washed, the various parts of the device being constructed and arranged in detail as hereinafter more particularly described.

Figure l is a perspective view of my washboiler, showing one corner cut away in order to indicate the interior construction of the device. Fig. 2 is alongitudinal section through the boiler on the line Y Y, Fig. 3. Fig. 3 is a transverse section on the line X X, Fig. 2. Fig. 4 is a perspective detail view of the false bottom and the various portions of the device secured thereto.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is a vessel or boiler in connection with which my improvements are used. This vessel may be of any suitable form, the form shown being taken for purposes of illustration only and the necessary variations in the form of the false bottom, dac., necessit-ated by the changes which may be made in the form of the vessel are all within the scope of my invention. In the lower portion of the vessel A a tap of any suitable form is provided. Handles c ct are provided at the opposite ends or sides of the vessel for convenience in lifting.

B is a false bottom which is located in the lower portion of the vessel, and consists of the substantially vertical sides b b, the ends b Zi', and the top, which is preferably gableshaped, as shown, in order to direct the rising water to the central line of openings hereinafter described. Perforations b2 are formed in the sides and ends of the false bottom, and it may here be pointed out that when the false bottom is inserted in the vessel there Will be a space between itssides and ends and the sides and ends of the vessel., and in order to hold the false bottom in place outwardly-extending corner-brackets b3 are secured to the corners of the false bottom. A series of holes b4 are formed in a line along the center of the false bottom, and tapering funnels b5 extend upwardly from the said holes, the smallest portion of the said funnels being uppermost. In order to secure the false bottom firmly in the bottom of the boiler or vessel, any suitable means may be provided; but the device which I have invented for this purpose is as follows:

a2 a2 are stops which extend into the boiler from the ends thereof.

h6 b are two loops of Wire bent to form the spiral springs bi at their lower portion and their lower ends being soldered or otherwise firmly secured to the ends of the false bottom B. bs hs are plates, of tin, sheet metal, or other suitable material, which are secured to vthe said wire loops, and their lower ends b9 are curved downwardly and inwardly, their upper edge being preferably dat. It will thus be seen that when the false bottom B is inserted in the vessel A the lower ends b9 will pass over the stops a2 and when the upper edge of the sheet-metal plates bs have passed `the stops t2 they will spring in and hold `the false bottom securely in place. In order to remove the false bottom, it is only necessary .to take hold of the two loops b b6 and bend them inwardly until the edges of the plates bs are beyond the edges of the stops a2, andthen the false bottom may be lifted straight up.

C is the cover of the boiler. This cover is supported loosely by its edges resting on the edges of the vessel A, and the bottoni c of the cover, which is preferably slightly gableshaped, is somewhat below the level of the top of the vessel A. A line of holes c' is formed along the center of the cover, these IOO holes corresponding in position and number to the holes h4 in the false bottom B. Funnels c2 extend downwardly from the holes c and cover the upwardly-extending f unnels b5.

c3 represents perforations which are formed over the entire bottom surface of the cover C.

c4 is a longitudinal bridge secured at its ends to the ends of the cover by any suitable means, the object of this bridge being to deiiect the water and steam rising from the conical tubes or funnels c2 back upon the cover.

c5 is a handle of suitable form which is secured to the bridge c4 in order to assist in removing the cover. In order to secure the cover in place on the boiler, any suitable means may be employed, such as the springsnaps c6 c6.

In using my washboiler for cleansing clothing and the like the clothing is loosely placed on the false bottom and around the funnels b5. A quantity of water is then poured into the boiler, in which a suitable amount of soap or other cleansing compounds has been dissolved. The boiler is then placed over the fire, and the water below the false bottom B as soon as it becomes heated will rise through the tunnels h5 and c2 and will then pass through the perforations c3 in the cover C and will circulate downwardly, completely cleansing any material which may be in the boiler, and the water will then return beneath the false bottom B by means of the perforations b2.

The advantages of the downwardly-Haring funnels c2 are that they enable the cover to be very readily set in place, owing to the wide mouths with which they are provided at their lower ends. At the same time the openings at their upper ends are very little, if any, larger than the openings at the upper -ends of the funnels of the false bottom. Consequently the water cannot return through the holes in the cover, but will return by way of the perforations. rlhe bridge assists in distributing the water as it rushes up through the funnels evenly over the perforated cover, and the result is that the water is evenly distributed and circulates'through the clothing which is to be washed.

It will be understood that in the construction and arrangement of the details of the machine it maybe found in practice that certain changes will be necessary. For example, the number of funnels h5 might be varied or the shape of the vessel, also the shape of the false bottom; but all these changes which are within the scope of mechanical skill may be made Without departing from the spirit of my invention.

What I claim as my invention isl. In a device of the class described the combination with the outer boiler or casing of a removable false bottom located therein and provided with perforated supporting sides or flanges, said false bottom sloping inwardly and upwardly toward the center, and having a central hole provided with an upwardly-extending funnel, a cover suspended byits edges on theedge of the boiler,the central portion of said cover being perforated and located below the upper edge of the boiler, said cover having a hole provided with a downwardly-flaring funnel, said funnel in the false bottom extending into the funnel in the cover, a deilecting-bridge secured to the cover and extending over the openings above the downwardly-extending funnel and adapted to deect the water rising from the funnel toward the sides of the perforated cover whereby the water is prevented from spilling and an even distribution is obtained, means for holding said false bottom in its proper position in the boiler and means for securing said cover to the boiler as and for the purpose specified.

2. In a device of the class described, the

combinationwith the boiler, ot' a false bottom located therein, spring-wire loops secured to the ends of said false bottom and extending upwardly therefrom, metal plates secured to said loops and stops on the inner walls of the boiler designed to coact with said plates to hold the bottom in place, substantially as described.

In a device of the class described the combination with the boiler or casing and the false bottom located therein, said boiler or casing having suitable stops extending through the ends thereof, of upwardly-extending wire loops formed with a spiral spring at their lower ends and secured to said false bottom, plates of tin or sheet metal, secured to said wire loops, said plates having inwardly-curved lower portions and their upper edges being adapted to engage the said stops as andfor the purpose specified.

4. In a device of the vclass described the combination with the boiler, of a false bottom located therein,.and comprising substantially vertical sides and ends, and a gableshaped Lipper portion, holes or openings being formedin said sides and ends and acentral line of holes being formed along the ridge of said gable-shaped upper portion, tubes or funnels secured in said holes and extending upwardly,

.a cover suspended by its edges on the edges of said boiler and the central portion of said cover being perforated and located below the edges of the boiler, a central line of holes being formed in the bottom or central portion of said cover, downwardly-flaring funnels secured in said last-named holes and extending over the tops of the upwardly-extending funnels secured to the false bottom, a longitudinal bridge secured to said cover directly above said central line of holes, means for holding said false bottom in its proper position in the boiler, and means for securing said cover to the boiler as and for the purpose specified.
