PAT NT .o'FFic This invention relates to means for mounting dishand clothes-washing machines, and the like,

in a manner enabling their being folded with respect to their support, and has for one of its objects provision of means whereby such a device may be folded beneath a sink or the like when not in use.

Another object of this invention is the, provision of such a foldable mounting enabling manual handling and moving of a relatively heavy machine with the expenditure of very little effort.

A further object of this inventionlies in the provision of such a foldable mounting which may be quickly and positively locked in the opened position to support the machine as rigidly as if it were carried upon a mounting of conventional construction, and which lock'may be quickly and easily released.

Other objects and advantages will be apparent from the following description wherein reference is made'to the accompanying drawings illustrating a preferred embodiment of my invention,

similar arts throughout the several views.

In the drawings: Figure 1 is a side elevational view showing an application of my improved roldable mounting to the support of a washing machine, shown carried thereby, the mounting being in opened position and the machine carriedtherebyread for use.

Figure 2 is a detail side view, partly in e1e .vation and partly section, of my improved mounting, the tub supports carried thereby being fragmentar ily shown. I

, Figure '3 is a front elevational view showing a washing machine supported upon improved standard and partly folded away beneath a also showing in dotted lines the position assumed by the device when fully folded beneath the sink.

Figure 4 is a view showing in top plan the arrangem'ent of Figure 3, "a1so showing in dotted lines the .pOS'lt'iO'll assumed, by th ii'l'i'lfl when folded away beneath the sink, and

Fi ure 5 is a detail fragmentary sectional view taken substantially on the line 5+5 or Figure 2', and looking in the direction-or the arrows.

Referring now to the drawings, reference char actor '10 indicates a may be secured to a floor or the like, as by screws 11, and whicnrigidl supports in vertical position the cylindrical post '12. The post, as shown in Figure 2 may be tubular. Rotatably supported upon the post 12 is a downwardly projecting sub-base or support which sleeve 13 carried by and integral with a housing 14. The housingl provides a journal and. support-fora horizontally disposed tubular shaft 15. For added rigidity a bracing web 16 and a laterally positionedbearing 17 carried thereby 1'n alignmentlwith the bearing 18 formed in the housing; may bejprovided; The horizontal shaft 15 is preferably rotatable in the bearings 17 and 18. The washing machine tub or other device desiredlto'be carried by the support may be rigidly affixed to the horizontal shaft 15. As here shown, the tub, designated. 20, is not directly aifi xed to the shaft, but to the legs 21, which are in turn secured to the shaft 15 by means of the saddle 22 which maybe formed integrally with the legs if desired, and which carries a central sleeve portion 23- through a threaded boss 24 of which. a set screw 25 engages to firmly secure the saddle, and consequently the legs and the tub carried thereby, to the shaft 15. It will thus be apparent that the tub may be swung about the axis of the shaft 15 and thatthe shaft turns with it. The weight of the tub is counter-balanced bye, counter-balance spring 26, contained in the housin .14.. The inner end of the spring engages a slot 15 in the shaft 15 to constantly urge the tub toward upright position, and as shown in Figure 5 the outer end is adjustably secured to the side of the housing 14 by means of the clevis pin 14. having a threaded-extremity 14 extending through an aperture 14 in the housing and carrying the, nut 14 threaded thereon, by means of which the tension of the spring may be adjusted. A similar but oppositely positioned aperture 1143 is'also provided in the housing through which the stem of the pin may pass in like manner when thesprlng is reversed in position to enable swinging and) counterbalaneing the machine about the shaft 15 in the opposite direction. Reversing the spring is accomplished by merely removing thepin from the aperture and removing the spring from the shaft, its inner extremity sliding onto! the slot, and turning the spring over, placing the stem of the clevis pin through the opposite aperture. The spring will then counterbalance the machine in the opposite direction. Y 7

The tube may be maintained upright by the slid'able locking pin or detent 28, which is engageablein an aperture .29 in one of the legs 21, as shown in 2. The pin is normally urged into the aperture by the compression spring 30 and may be retracted by the link 31 through the agencyof the lever 32, and the operating rod. 35 The operating rod'is formed with a handle portion 33 end of the hollow shaft 15, and a suitable aper tured boss 37 formed in the housing 14, as shown, Adjacent the extremity of the lever 32 the operat: ing rod is formed with a crank portion 'saupon which is fitted a connecting rod intheform of an elongated link 39 which extends downwardly and is connected to, to operate, apin- 40; engageable" in a suitable aperture 41 in the sub-base 10.to

prevent rotation of the support about its vertical axis. A compression spring 42 may be provid ed to urge the pin into the aperturegthe pin and spring being housed in the radial. extension .43. carried by the lower-extremity -of-the sleeve or elongated boss 13. It will'thusbe seen that ,.by

turning the operating rod 35; by means of the handle 33 the pin 40 may be retracted, whereupon the support and the machine carried thereby may freely beswung about the vertical axisfurnished by the shaft 12, and that upon turningv the operating rod in the opposite direction the pin may again be allowed to enter the same or another aperturein the sub-base to secure .the machine in any desired position with ,respect to' said axis,

depending upon the arrangement. andpositionr. aperture or apertures 41 in the sub-" ing of the a a base. It will also be seen that by pulling the operating rod outwardly the machine maybe. swung about a horizontal axis furnished by. the I shaft 15 to the position shown in full lines ,in'l Figure 3, at which point it is stopped .by en-' gagement of the bottom of the saddle 22 with the stop 44, carried by the bracing w'ebf16; or re-} versely it may be moved from thehorizontal' po--] sition shown in Figure 3 to the upright positionshown in Figure-.1, where it may be locked by the pin 28; in the manner described. v In order to enable folding the machinein the opposite direction, which is frequently desirable to enable folding it signs, and to still permit the machine to be in-the same position when opened for use, Ipreferably sov form the parts carried by thesaddle 22 which engage the shaft 15 as to permit reversing the saddle and so the entire machine with respect to the shaft. It will be seen that the sleeve portion 23 is substantially in the center. of .the. saddle, while the two end shaft-engaging pore,

tions are substantially alike. This enables re. moving the shaft 15, reversing the machine, and" replacing the shaft. If the counterbalance spring. 26 is then alsoreversed inthe manner previously described, the support will function in precisely the same manner, but will fold in the opposite; direction. One of the'apertures 29 for the pin 28- is'of course placed in each leg, as shown in Figure 2.

Figures 1, 3, and 4 show an-application of 'my support to' the mounting of a washing machineyor the like so that it may be-folded andswung away beneath a sink. The sink, whichyisgsomewhat conventionally sh0wn,'is designated 45, and Fig* ure 1. :shows the machine in the' uprightposition inwhich it would normallybe used.---,:Figur e 3 shows in full, lines the first stepin folding the,

beneath sinks of varying de' machine in one direction, which comprises swinging it about the horizontal shaft 15 to the position there shown. This position is shown in plan view in full lines in Figure 4. The machine may then be swung about its vertical axis upon the shaft 12 to the position shown in dotted lines in Figures 3 and 4, in which it is completely beneath the sink and out of the way. When the counterbalance spring ,and .the machine arereversed in position,'the latter of course folds awayin the reverse direction, but otherwise in the same manner: ,-.-While it will be apparent that the illustrated embodiment of my invention herein disclosed is 'well' c'alculate'd to adequately fulfill the objects and advantages primarily stated, it is to be understood that the invention is susceptible to variation,

' modification and change Within the spirit and scope of the subjoined claims.
