To all whom it may concern:

Be it known that I, ANNIE WARD, citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Collapsible Washtubs, of which the 'followin is a specification.

My invention r'e ates to new and nseful improvements in wash tubs, the primary object of my invention being the construction of a collapsible wash tub which, when not in use, may. be stored in a relatively small space. i

A further object of my invention is to provide an all metallic collapsiblewash tub having a body portion consisting of a plurality of telescopic ring shaped members, one of which is closed at one end to provide a bottom for the tub, said closure being extended to provide an exterior peripheral flange forming a seat for the remaining members when the body is collapsed.

A still further object of my invention is to provide means for positively holding the members making up the body of the tub in extended position when the tub is in use and so preventing inadvertent collapsing of the tub. And a still further object of my invention is to so arrange this locking mechanism that the locking bars or braces constituting the locking mechanism may be swung inwardly and out of the way when the tub is collapsed.

With these and other objects in View, my invention will be more fully described, illustrated in the accompanying drawing, and then specifically pointed out in the claims which are attached to" and form a part of this application.

In the drawing: Figure 1 is a perspective view of my improved wash tub as it would be in use; Fig. 2 is a similar view, showing the position of the parts when the tub is collapsed; Fig. 3 is a fragmentary vertical sectional view showing certain details in construction; Fig. 4 is a perspective view of one of the locking devices employed in securing the body members of the tub in ex tended position; the parts of the locking devices being shown in unassembled relation.

Correspondinga'nd like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

In the preferred embodiment of my invention, the body of the tub is made up of lu'rality of telescopic sections 10, each of l a w lich is ring-shaped, tapering from its upper to its lower end. All of the sections taper uniformly and the internal diameter of the lower end of each section is slightly less than the external diameter of the upp'er end of the next section b'elow'. Because of this, when the sections are moved to extended position, the upper and lower ends of adjacent sections will friotionallv engage weight and are preferably tinned, galvan ized or otherwise treated to prevent their oxidiza'tionor corrosion; Although a wash tub having but three sections is illustrated in the drawing, it will be clear that as many sections as deemed advisable, and sections of any desired height, may be employed.

The innermost or smallest section is closed at its lower end to provide a bottom 11 for the tub and this closed end is projected externally to provide a circumferential flange 12 of suflicient width to support all the sections of the body member of the tub when said sections are collapsed. The upper edge of the outer or largest section which, consequently, is the upper section, is reinforced by a wire-ring 13 which surrounds said section and about which the upper edge of the section is rolled as clearly shown in Fig. 3. This upper section is provided at diamet rical'ly opposite points with swingingly mounted handles 14 of any desired type which not only serve as a means for moving the tub about when in use, but also as a means for drawing the various sections of the tub to extended position as it will be clear that if the lowermost section of the tub is held against upward movement and the upper section raised by grasping the handles 14, the entire tub will be extended. The lower section is preferably reinforced at a point adjacent the bottom of the tub as shown at 15 and provided with a drain openin having a closure 16 of any suitable type, t e only limitation being that this closure be of such a style as not to extend unduly beyond the body member in order that it will not interfere with the proper nesting of the upper body members about the lower.

In order to lock the telescopic body members of the tub against collapsing when in extended position, I provide a plurality of locking devices, indicated as a whole by the numeral 17, these locking devices being located at spaced intervals about the tub. Three or more of these locking devices should be employed and as they are all identical in construction a description of one will sufiice for all. Each of these looking devices includes a plate 18 which is soldered or otherwise secured upon the upper face of the flange 12 and which is provided with a longitudinally extending slot 19. A pin or stud 20 extends upwardly from this plate between the slot and the body of the tub and preferably midway of the length of the slot. A hinge plate 21 is riveted or otherwise secured to the outer face of the upper body member 10 of the tub, one of these hinge plates being provided for each of the slotted plates. As best shown in Fig. 3 of the drawing, the intermediate portions of these hinge plates are curved outwardly and upwardly and then inwardly as at 22 to engage about the reinforcing bead formed by bending the upper edge of the body member about the binding wire 13. The ex tended upper end of the hinge plate is then cut-away to provide an upwardly and outwardly directed tongue, the free terminal of which is bent to form a bearing 23 for the pintle pin 24 of the hinge.

A locking bar or brace 25 is cut-away at one end to provide a tongue 26, the terminal of which is bent to form a bearing 27 co-act ing with the bearing 23 to receive the pintle pin 24 by means of which the locking bar is hingedly connected to the hinge plate in such a manner that the locking bar may be swung downwardly to extend in spaced relation along the outer face of the tub as shown in Figs. 1 and 3 or swung inwardly to rest within the tub as shown in Fig. 2.

The free end of the locking bar is provided with a laterally directed bifurcated terminal 28, the arms of which are adapted to seat one upon either side of the upwardly directed stud 20 of the co-acting plate 18 when the tub members are in extended position and the locking bar is swung to the position shown in Figs. 1 and 3. Swingingly mounted upon the outer face of the locking bar 25 adjacent its lower end, is a clamping lever 29 having a cam nose 30 adapted to work in the slot 19 of the plate 18. This clamping lever is so arranged that when swung at right angles to the locking bar 25, its lowermost portion will be above the lower end of said bar while, when swung upwardly into alinemen't with the locking bar, its cam nose will extend below the lower end of the locking bar.

In operation, assuming that the tub is collapsed as shown in Fig. 2, the parts of the body of the tub are drawn to extended position by holding the lowermost member down and raising the uppermost member by the handles 14. The locking bars are then ing levers are swung upwardly into alinement with their clamping bars, thus forcing their cam noses into the slots 19 of the respective plates 18 and exerting upward pressure upon the respective locking bars to further expand thebody member.

The engagement of the arms of the bifurcated terminals of the locking bars about the studs of the slotted plates relieves the hinges by which the locking bars aremounted upon the upper tub sections from lateral strain and also tends to prevent rotation of the upper member of the tub with respect to the lower member when in extended position. The clamping levers not only serve to more completely extend the body of the tub, but also, because of their engagement in the slots of the plates 18, serve to securely lock the locking bars against outward swinging movement which might otherwise free them from the flange 12 and permit collapsing of the tub.

The peculiar formation of the hinge plates 21 and manner in which they engagebeneat-h the reinforcing head of the upper body member is such that the strain exerted upon these hinge plates by the locking bars is exerted to a considerable extent against the reinforcing bead, thus relieving the rivets or other fastening devices, by which the hinge plates are secured to the tub, from a great part of the strain which they otherwise would have to support.

lVhile I have illustrated and described a collapsible tub construction in all its de tails and with considerable particularity, it will of course be understood that I do not wish in any way to limit myself to the specific details of construction, so illustrated and described, as various changes, within the scope of the appended claims, may at any time be made in the tub construction, without in the slightest degree departing from the spirit of my invention.
