end of the socket member or socket 3, and

also has an "annular shoulder upon which is recelved the under edge of said socket. The anti-slide member is recessed 1n the up per side, as represented at 16, to receive the.

bottom part of the holder 12, and said memher is secured tosaid holder by means of a screw 17 which is passed upward through the axial center of said member to be tapped into the axial center of said holder.

The anti-slide member "13 is preferably made of rubber, and preferably has its bottom recessedto make of said member a shetion cup. In the present example there are in the bottom of themember 13 a'central recess 18 and an annular groove 19for SIICtlOIL Thus itis seen that the anti-slide member not only grips or hugs the surface, with which it is intcontact, in a.,manner to produce frictional resistance and thereby pre-;

vent sliding, but also forms asu'ction connection with such surface, whereby sald member is held still morefirmly in place,

thereon. While dependence for immovability might be placed on either the frictionalresistance factor, or on the suction factor,

either alone, it is preferred, for thesak'e of greater secu'rlty, to provide and employ ananti-slide member which possesses both of these factors; i i

The transmission case 1 is preferably in the form of a hollow enclosure for containing'transmission mechanism (not show n)l" The transm ssion will preferably be ar ranged to actuate shafts for atub anda wringer as will be hereinafter referred to. The case 1 functions asthe body for the carriage and is injturn supported'at opposite sides or ends by revolvable and anti-slide members and is sufficiently rigid to facilitate the rolling of the carriage about. This case may be madeof a plurality of securedto gether complemental sections asshown. When the case/1 is in horizontal position,

the bottoms of'the wheels 11 and the bottonl of the anti-slide member 13 are'in' the same horizontal plane. Inother words, whenthc wheels 11 and the anti-slide member 1 am rest on the floor, the case 1 is in'a horizontal" two feet,*as 33. Thewheel 32 has an aXlebo-lt position.

The case 1 has'on top over the socket 3 a flange 20 into which is'set and to which is pinned at 21) a wringer column 22. At the upper endthe column 22 has pinned theretd (at 23) a hub 24 of a handle 25. i The handle 25 projects forwardly and is furnished to facilitate raising he carriage at the" front supported thereby, when normally disposed.

rests with thejwheels 11 and the anti-slide member 13, of the foot at the front end, on the floor, and understood that the weight of the motorb-is. not suflicient alone to rock said case, through the medium of the arms '7, upwardly with the'a-Xles 8 as a center. The

weight of the motor 5 is a factor, however, in" assistin to rock the case lupward'ly on the wheels '11, said motor" then swinging downwardly, when the handle25 is grasped and said case is raised at the'front end to take the anti-slide member 13 off of the floor, and'also inassisting tobalance' the machine while still tilted andmoved about by means of said'handle. As'soon as the upward force applied to the handle 25 is' removed the case 1 rocks downwardly until the anti-slide member 13 again rests on the flobr, carrying upwardly at this time the motor 5. The motor is always quite'neart'oithe floor and therefore prevents the machine from being upset rearwardly when tilted by 'meansof the handle2'5. 1The whee1s 11 are so wide apart'that tilting in a'lateral direction isprevented.

The weight of the parts above onthe antislide' member '13-'f0'rc'es said member into close contact with the floor and fthus'causes to be set up a degree of frictional resistance which in itself or alone"fre'quently would be sufficient to "hold' said member in" place, but in addition a-partial-vacuum is created in therecess 16 and the groove 19, and this adds sufficient additional staying force absolutely-to prevent'movement ofthe carriage in any direction until said me'mber is lifted from the floor; The suction of the member 13 is not suificient, however, to interfere with the raising of the carriage atthe front end, and-when said carriage is raised'and said member is clear of the floor there is'nothing to prevent movingfthe carriage on the wheels 9 in any direction.

In the carriage illustrated in the last two views, there are a single wheel, as '32, and

34 mounted in'two bearings 35 depending from the bottomof the case 1 forward of the motor 5, said bolt being held'in place by' a nut 36. The'ffeet 33 are fastenedto two holders that are received in socket members 38-38 located adja'centto the front end of said case. The socket members 37 extend down alongside and below the sides of :the front-end portion of the case. Otherwise the construction of the second carriage is practically identical with that of the first, and

the wheel 32 and .the feet 33 respectively function in a very similar mannerto that in which the wheels 11 and the foot 13 function,

only in the one case the wheels at all times prevent the-machine from tipping over sideways, and in the other case the feet when on the floor prevent the machine fromtipping over sideways, but such tipping can only be prevented by the operator at such times as said feet are off of the floor, and the operator must balance the machine while being moved about on the single wheel. Ordinarily the first carriage is to be preferred;-

The rotary and anti-slide members in the second carriage are smallerthan corresponding members in the firstcarriage;
