FOLDING- BATH-TUB.

Specification of Letters latent.

Patented Dec. 17, 1912..

Application filed February 25, 1911. Serial No. 610,700.

To all whom it may concern.

Be it known that I, FRANK HENRY Russ, a citizen of the United States, resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Folding Bath-Tubs, of which the following is a specification.

The development of folding bath tubs has received considerable attention and applications for patent on the development have been made by myself and others until there remains but the new and advantageous features of the construction, to be considered from a patentable standpoint. Even some of the features found in this particular device are also to be found in my application for a similar device which was filed June 10th, 1910 and bears Serial #569,733.

In devices of this general character the particular advantages lie in the efliciency of, the device when used as a tub, in its lightness for transportation, and in its construction that allows it to be folded into a compact whole. It is with this last feature that I have particularly to do in this application.

The following is what I consider the best means of carrying out this invention.

The accompanying drawings form'a part of this specification, in which:

Figure 1 shows the completed device, it is in side elevation. Fig. 2 is an end view corresponding to Fig. 1. Fig. 3 shows, in side elevation one of the legs and its junction with the side frame in this figure the receptacle is omitted. Fig. 4 shows a modification of the hinge member. Fig. 5 is a view corresponding to Fig. 3 though with the legs folded.

Similar reference numerals indicate like parts in all the figures where they appear.

The numeral 1 indicates the tub or receptacle for the water, it is of fabric, oiled silk or canvas, or canvas impregnated with rubber so as to make it water proof. The tub is oblong and when the sides and ends are upturned the surplus materialis folded in without cutting and then clamped into position. In this way I obtain a complete receptacle without stitching.

2 and 3 indicate the side rails which may be of wood, to these the tub is secured by means of the metallic fastenersor nails 4:.

mediately' adjacentand-supporting the side rails 2 and 3. The legs which support the 6, and the legs which support the side rail -3 are numbered 7 and 8.

The legs do not extend directly from the side rails downward but are secured in such a manner that they extend inward and cross in airs. The legs 5 and 7 being secured to get er at mid-height by the pivot 9 and the legs 6 and 8 are similarly secured. by the pivot 10. The blocks 11 are arranged upon the pivots 9 and 10 and between the pairs of legs secured by the pivots in such a manner as to support the legs when they are in their operable position and to relieve the pivots 9- and 10 from the strain which mighktend to shear the pivots. I

One of the most important elements of my device though one which has not been before described is the means for connecting the legs reliably to the side bar that they are intended to support. This means is the hinge l2 and its peculiar construction makes it well adapted for the duties it is called upon to perform. In its simplest form that shown in Figs. 1 and 2 it is made of sheet metal about {-3 of an inch thick and in shape is not unlike the letter. 5., having a long and a short end. In the long end I provide two holes which are to receive wood screws. to secure it to one of the ends of the side rail 2 are numbered 5 and legs. A single hole is produced in the short endand a strong screw which is to act as thepivot 13 secures this end loosely to one of the side bars.

In Fig. 5 I have shown the advantages to be derived from the peculiarly constructed hinge that is, that the legs fold under the rolled tub in such a manner as to allowsufiicient room for the 'tuband yet cause the legs to fold in a line parallel to that ofthe side bars.

Because of the relative operable position of the legs the length of the shorter end of each of the L hinges mustbe determined by the position they are to occupy, for instance the length of the shorter and of the hinges on the legs 7 and-.8 'is less than that on i the legs 5 and 6 for the reason that legs 5 and 6 must travel a greaterarcto assume and 8 4 Modification may-be made within the their proper place outside of the legs '2' its parting from the principle or sacrificing the advantages of this invention.

glhe connection of the hinges 12 to the me gnbers with which they are to Serve might be strengthened or even improved if the side rails and legs were slitted at their adjacent portions allowing the hinge to be secured and operated within the slit. ,A similar construction is well known in other arts.

Fig. 4 shows a modification that may be advantageous.

Having carefully and fully described my invention What I claim and desire to secure by Letters Patent is A folding bath tub having a frame of parallel side members, a leg at each end of each said side member and hingedly connected thereto, said legs arranged in pairs approaching and crossing each other, a pivot through said legs at the point of crossing, and a block loosely suspended upon said pivot, said block being provided with a pinrality of extensions, two bearing upon each said leg, and a tub operable with the frame for the purpose set forth.

Signed at New York city, in the county of New York and State of New York this 25 day of February, 1911, in. the resence of two witnesses.
