connect the shell therewith, thus to complete the frame structure and provide-a watercontaining receptacle; and a suitable packing, such for instance as sheet lead, is 1nterposed between the flanged edge of the shell and the side frames, which is tamped to produce a water-tight joint. With such a structure, it is a serious fault to utilize the shell as a component part of the frame.

In case a joint leaks, it must be repaired from the inside of the receptacle, which operation is attended with considerable difficulty. In case the shell wears out, or is so injured that a new shell is required, the old one. must be detached from the side plates to admit of a new one being substituted, and when detaching the same, the entire, or substantially the entire frame structure must be disassembled. In case of a fire, the lead packing usuall melts, and the tight joint is destroyed. ence, repairs of an extensive nature can only be made satisfactorilyat the factory, which necessitates shipping the machine to the factorywith the attendant delays in transit as well as the additional expense.

I have discovered that by providing the side-plates with means for rigidly supporting them in their respective relative positions independently of the shell, that the shell may be connected with the side-plates by a very simple form of joint, which, in case of leakage, may be repaired from the outside of the shell, or case a new shell is required, said new shell may be secured in place at the laundry, Without the necessity of ship Jingthe machine to the factory.

Furt ermore, a type of joint may be employed wherein the ends of the shell may be devoid of flanges, and rivets are not required to connect said ends with the side-plates. Such joint may consist of a groove formed -in the inner side of each side plate, which Specification 6;" Letters l fatentf v P tented June 22, 19 20.

grooves areadapted to receive the ends of the shell and said grooves are made much wider than the thickness of the wall of the shell to provide spaces in the grooves at one side of the wall of the shell to receive a mass of molten lead'or equivalent packing material which may be run into the grooves after the shell has been placed therein. The wall of the shell maybe arranged contiguous the inner Wall or'side of thegrooves, and in such case, the mass of molten lead will be arranged on the outside of the'wall of the shell. This type of joint for this purpose has many advantages but 'by means independent of the shell, such joint cannot be employed for the reason that it is enough to connect the shell with the side plates and hold said parts assembled, so that they form component parts of the frame structure.

Figure 1 is a front elevation of a washing machine embodying this invention.

Fig. 2- is an end view'of the same.

Fig. 3 is a rear elevation of the same- F 4 is" an inher side view of one of the side plates of the frame structure which also serves as an end wall for the water-contaim in receptacle.

ig. 5 is' a fragmentary sectional detail view of a joint which may beemployed.

Fig. 6 is a similar detail view of a modified form of joint;

The frame-structureof the machine, as here shown, consists of a pair of side-plates not strong 1 porting legs 13; a substantial bar or beam 14 arranged horizontally to rigidly connect said side-plates together at the rear of the machine, said bar or beam being arranged with its ends abutting against adjacent faces of elongated ears 15 on the side-plates and secured thereto by screws 16 extended through said ears and into the ends of the beam; and several long stay bolts 17 which are rigidly connected to the two side-plates, there being four such bolts here shown, two of which are arrangedwithin the margins of the side-plates, and two are arranged outside of the margins of the side: lates, being. at the tops of. the supporting egs. However, any other. suitable form of bar, beam, or stay bolts, or equivalent members may be employed, the idea being to provide ample connecting-means for rigidly connecting together the side-plates, so as to form a rigid which is connected with the sidepl ates, and which forms in connection therewith, a water-containing receptacle. 7

20 represents such 'a shell, which is or semi-circular formation in cross-section, and adapted for engagement with the lower half or portion of the side-plates, so that together with said side-plates, a water-containing receptacle is produced. p

Each side-plate has a deep groove 21 formed. on its inner side or face at or near its margin adapted to. receive .one end of the shell. This groove may be formed by providing a pair of

parallel flanges

22, 23, on the inner side or face of the side-plate, as represented in Figs. l to 6. The ends of the shellare placed in these grooves, being arranged therein contiguous the inner wall of the grooves, see Fig. 5, and the grooves are.

made of sufficient width to provide spaces outside of the. wall of the shell adapted to receive a metallic packing, such, for instance, as molten lead or spelter. In Fig. 5, a groove is represented as havingsubstan tially parallel sides and the end portion of the wall of the shell may be more or less roughened thereby to. more securely enable the metallic packing to hold the shell in place. In Fig. 6, a dove-tailed groove is formed which obviously more securely holds the metallic packing in place. The metallic packing inherently unites with the-metallic side-plates and shell, so that a water-tight joint is produced.

lVith this structure, it will be seen that in case the joint leaks, it may be easily repaired at the outside of the shell, or in case the shell needs repairs, or a new shell is required, the old shell may be removed, and a new shell supplied without theqnecessity or disassembling the entire structure or sending the machine to the factory, or in case of a fire, and the metallic packing melts, new metallic packing may be easily. supplied without disassembling the machine.

The side-plates of the machine each have an elongated radial. slot 80 extended to .its center. or thereabout to enable the usual shaft to be placed in position, and suitable covers 81 are provided for these slots.

Furthermore, suitable means are provided for closing the top of the water-containing receptacle which may comprise a circularlyformed plate 35, rigidly connected to themargins of the side-plates, and a circularlyformed cover 36 hinged thereto.

I claim e 1. In a washing machine, the combination of a shell, a pair of spaced-apart.side-plates having grooves in their-adj acent sides, a plurality of supporting members extended between said plates rigidly connectingthem together at their margins to form a rigid frame structure and to maintain said side- 2. In a washing machine, the combination of a shell, a pair of spaced-apart side-plates having grooves in their adjacent sides, a plurality of supporting members extended between said plates rigidly connecting them together at their margins to form a rigid frame structure and to maintain said sideplates in spaced-apart relation independently of said shell, said shell having its ends receivedfin the grooves in said side-plates, contiguous the inner walls thereof, and metallic packing arranged in thegrooves at the outside of the shell, said shell and side-plates forming a water-containing receptacle.

3. 'In a washing machine, the combination ofa shell, a pair of spaced-apart side-plates having grooves in their adjacent sides, elongated ears in said plates, a bar extending horizontally and connected to said ears, a

plurality of long bolts connected to the margins of said side-plates, thus to form a rigid frame structure andtomaintain said sideplates in spaced-apart relation independently of said shell, said shell having its ends received in the grooves in said side-plates, and a mass of metallic packing compacted in the grooves with the ends of the shell on the outside of the receptacle, said shell and side plates forming a water-containing receptacle. j

4. In a washing machine, the combination of a pair of spaced-apart end-plates, means rigidlyv connecting and separating them, a curved shell disposed between said endplates, and means whereby said endplates and shell are connected tov form a water-tight joint comprising, said endplates having deep grooves in their adjacent faces in which the ends of said shell are received with its inner face contiguous the in-- ner edges of the grooves, said grooves being materially wider than the thickness of the shell, and a metallic packing compacted into.

the spaces between the shell and the groove on the outside of the shell whereby to force the inner face of said shell into firm contact with the inner edges of the grooves and externally seal the vessel.

Intestimony whereof I have signed my, name to this specification in the presence of two subscribing witnesses.
