These bars 25 are of such length that when fully inserted the lower ends thereof are substantially flush with the lower ends of the leg formations and the channels 28 of proper size to embrace the pairsof curled edges 23' tightly therein so that when applied, the flanges 22 are tightly clamped together and the adjoining sections thus rigidly and inseparably joined to form a strong substantial tub support, the legs of which are effectively reinforced throughout their length by the connecting bars.
Obviously any desired number of sections may be employed instead of four quarter sections as shown herein and joined together in like manner with channeled bars 25.
Preferably the bars 25 are of double channeled form each with a channel 28 along the inner side, preferably like the channel 26, for mounting brackets or other fittings on the bars 25, these inside channels 28 being employed in the present structure for mounting tub holders or seats 29, brace connections 38 and caster sockets 3| in appropriate places thereon. Each of these brackets or fittings 29, 30 and 3! has an elongated T-shaped flange 32, of a shape and size to fit snugly in the channel 28, which is slipped into the channel 28 to the proper elevation and locked therein at the selected place. Such locking may be accomplished in any convenient manner, either by squeezing the embracing walls of the channel 28, by means of an appropriate tool, into a sufficiently tight clamping engagement with the respective T flange to lock the flange 32 rigidly therein, or by squeezing the walls of the channel along the unoccupied portions to reduce the size of the channel between and at the ends of the flanges 32 as indicated at 33 or by punching the channel walls at the ends of the flanges 32 as indicated at 34, or by providing the flanges 32 with depressions 35 at suitable places and punching the metal of the channel walls therein as indicated at 36.
or other means may be employed, although it is preferred to avoid pins and the like which may necessitate providing the bars 25 with openings or apertures which might impair their strength. These bars 25, being of uniform cross sectional shape throughout their length, may be conveniently made in long lengths by an extruding process and merely cut to proper length, and are of a metal that may be readily shaped to clamp or lock the flanges 32 of the fittings 29, 38 and 3| in the chahnels 28, aluminum being preferably employed, not only because of the advantage of light weight, but also because subsequent shaping thereof as in clamping the flanges of the fittings in the channel or in contracting the channel between and at the ends of the flanges as at 33 not only does not impair the strength thereof but in fact increases the strength and rigidity thereof, thereby enhancing their effectiveness as supporting and reinforcing elements. a v
Each channel bar 25 has a tub holder or seat 29 secured in the channel 28 thereof at the upper end, all being at the same elevation to engage the bottom margin of the tub i0 which is curved as at 31 and the seating faces of the tub Any one ormore of these locking means may be employed,-
holders 29 being correspondingly curved as shown in Fig. 3 to properly fit same and each channel bar 33 also has a caster socket 3i secured in the channel 28 thereof at the lower end to receive the stem of a caster 39 by which-the washing machine is movably supported, said caster sockets being preferably formed with a flange 40 at the bottom engaged under the lower end of the inner half of the channel bar 25 within and concealed by the lower end of the respective leg formations I6.
A frame, part only of .which is shown, and indicated as a whole by the reference numeral 4| in Fig. 2, is provided within the assembled washing machine support to brace the assembled structure and provide a mounting for operative parts, and in the present instance comprises a platform portion 42 with a pair of brace bars 43 extending laterally therefrom near each end. Only one end portion of the platform 42 and the brace bars 43 at that ,end are shown in the drawing, but it is to be understood that the other end of said platform is similarly equipped with two sets of brace bars 43, thus providing four sets of such brace bars 43, each of which said sets is provided at its outer end with a fitting 44 for attachment to a brace connector 30 of the respective channel bar 25, thereby interlocking the four channel bars to frame 4!.
Each fitting 44 is provided at its outer end with a vertically extending pintle like formation 45, preferably with rounded upper and lower ends and circumferential grooves 46 and each brace connector 39 is provided with a correspondingly elongated stirrup 4'! with a substantially cylin drical opening 48 therethrough open along the inner side to receive the formation of the fitting 44 endwise therein. The walls of the stirrup 47 are malleable and after the formation 45 has been inserted in the opening 48 the stirrup walls are contracted by means of a suitable tool to engage the rounded end of the formation 45 and the grooves 46 thereof so as to lock the formation 45 securely and permanently in the contracted opening 48 of the stirrup 41, thereby securing the frame 4i likewise securely and permanently within the tub support and insuring a strong and effective bracing of leg formations thereof.
The housing l2 by which the wringer is supported and through which driving connections therefor are provided from the motor i4 is preferably secured to the side of the tub support, preferably between a pair of leg formations of one of the sections 11 as indicated in Fig. 2 and may be secured to such section in any convenient manner, and suitable openings will of course be provided through the wall of the section I! I from within the tub supporting structure. to the interior of the housing 12 for power communication, the particular manner of attachment of the housing H. to the section l1 and the arrangement of such openings thereto not being particularly shown as they form no part of the present invention.
From the foregoing it will be apparent that I have provided a construction and a method which may be advantageously employed in making tub supports for washing machines and other similar structures of assembled sheet metal sectionsthat the assembling of the sheet metal sections is greatly facilitated and the sections and other parts are securely and rigidly united in a manner to obviate any release or relaxation of the connections such as occur when bolts or other similar fastenlngs are employed; that all connections are made with reinforcing members so that no strain is imposed thereby on the.
sheet metal parts and in such a manner that there are no exposed connections or connecting means; that the connecting means for the sheet metal sections serve at the same time to effectively reinforce the assembled structure and are of such a character that their strength and rigidity is increased by the shaping thereof in the preferred manner of attaching parts thereto, and it is to be noted that the manner of attaching fittings to the channeled reinforcing members permits location thereof at elevations selected at the time of attachment without the necessity of previously shaping, drilling or otherwise preparing the parts for attachment of the fittings at a selected location.
While I have shown and described my invention in a preferred form, I am aware that various changes and modifications may be made therein without departing from the principles of my invention, the scope of which is to be determined by the appended claims.
