A To all whom t may concer/a.' Y;

Be it known that I, FRANKRioHAnDso YUBURGEss; a -citiaen'of the Dominion ofv Canada, residing at Ottaw a,in the Province 'of Ontario and lDominion ofCanada, have inf vented. certain new andi useful' [Improve- ;-ments in Scrub-Carts, off-which: the following is a specification, reference being,y had to the accompanying drawings, and to vthereference characters marked thereon; which ffoim a part of this specification.

f This invention relates'y to an improved,

A portable kneeling bench which I-herein des'- ignateas a scrub cartf 1 ,fg

In scrubbing floors with aescrubbing brush and soap and water, the scrub-woman is gfpbliged to kneel upon theifloor, which being hard, promotesfSertre'rne:fatigueV and so'ref 'Iovobviate this thescrub- J ness to the knees.` woman not .infrequently employs. a' small pad or cushion to kneel upon. This is only a temporary expedient, for the pad or cush-V` ion 4becomes moist and in 'timer communicates moisture to the:clothingr of the scrub.-v woman, which adds greatly toitheannoyance and inconvenience of the operator.

Moreover, there is no stability Vabout such.

an article and it frequently slips and slides about, making the scrubbin'goperation more difficult.,

vMy invention contemplates. a cushioned support for the scrub-woman to kneel upon, that will be comfortable and at the saine times suiciently raised from the floor to be free from becoming moist and damp, andthus communicate dampness tothe clothes of the operator; a devicewhich will be Vprovided with suitable rolle-rs so as to be readily movable as the scrubfwoi'nan proceeds with the scrubbing operation; and provided Vwith means whereby itmay be held `against movement in alg'ven spot while the act of scrubbing is being performed.

The nature and .advantages .of myinvention will be more readily apparent from an inspection of the accompanying drawings, and as I proceed with my specification.

In said drawings:

Fig. 3 is a side elevation. y In the drawings, the cart, lettered A, as a whole, is provided with a suitable floor or Vcushion supporting part l, which floor is i v q sonos-CART.- p

The constructionof these casters is not terial and further description will not ybe had,"inasmuch as any caster adapted fory free movement vof the article tov which it is ati tached, may be used.- Y It will Vbe observed that by reason of the under members 2,y 2,

and the dependingl casters 3,3, the floor l of Y I the scrub cart is raised anappreciable distance above the licor line designated by the. 'numeral' 5. l/Vhile a lesser number of casters may be used, I yrecomine1ic-l'fourfbe#V hand, the'use of four has' a tendency to check 4cause this number will not-make the ,mov-jI ability of the cart too free, Vwhile `on 'the other;

sudden movement of the cart suchas would easilyoccur if threecasters were used.'

It will be noted that the forwardeifids'ofv thejfloor l are preferably rounded a't` 6,' 6, Surrounding l'the two sides and' front mar-j giiisfa'nd the rounded ends Gfof the floor'l is an upturned flange member 7. l/Vithin this i flange member 7, and resting upon the floor 1, is any suitable padding or kneeling cushion S. To the forward end of the cart, I attach aVV suitable box 9'which may be a convenieiit receptacle for a vscrubbing brush,

soap or other Aarticles required in the scrubbing operation.

Mounted transversely ofthe floor and in suitable journal bearings 10, 10, attached to the under side of vthe transverse members 2,. 2, is'v a shaft ll. yond the outer margin of the sides of the flange 7, and at each end is provided with a brake disk l2 as shown inV Fig. 3. The brake disk 1 2 is mounted eccentrically of the shaft 11.` Attached to one 'of the eccentrically mounted brake diskslQ is a handle 14:.

VThis is preferably mounted upon the right A pair Vof out-V hand side of the device.` wardly projecting'pins 15, 16, are mounted This shaft extends be on the flange member 7, on the same side of the device as the handle, and serve to limit the throw of the handle 14, as clearly indicated by dotted and full lines in Fig. .3.

vWhen the operator is kneeling upon the cushion 8 and desires to havev the device remain stationary, she will seize the handle 14 and move it to its forward position, indicated in full lines in Fig. 3, whereupon'the fiat faces 17 of the cam disks 12 will be pressed downwardly until in contact withl the floor. In this position all movement of tion of the device, she will grasp the handleVV 14 and move it backto the rear stop 16, into vthe position shown in dotted lines in Figs.

operator finds that she is entirely free from danger of accidental slipping, andat the gin of the brake disk 12 entirely clear from the Hoor. i shift the position of the scrub cartby means of the rollers and a very slight movement of the body. In kneeling, upon this device in the act of scrubbing, the voperator naturally desires to cover as large an area as possible without shifting her position. To this end she may lean forward with out-stretched hand, and were it not for the brake disks 12, the kneeling device would slip out from undery her. With thesepbrakes applied to the floor, there isA no danger of the device slipping away or shifting its position.

- while the brake disk 12 inname@ and described is recommended from experience as a practical device, I do not desire to be limited to this particular means ofbrake,

` as it will be `obvious that any movement resisting device may be used; and while I have shown the cushion 8 upon the support 1, it is obvious that saidicushion may be dispensed with.

One of the principal advantages of myk invention consists in the fact that the scrubwoman when kneeling upon the cart, may

At such time the operator'mayl shift `it from point to point without arising susV therefrom; a simple pressure of the lhand Y sity of raising the body with each shift of position, the Work progresses much more rapidly. y y

' With the use offmy improved device, the

same time is provided with a soft cushioning fdevice `whereby the act of scrubbing isfacilitated and made easier. v The device is simple in construction, Vcheap to manufac-` ture, and has-no parts to get out of order; y I claim as my'invention: i As a new article of manufacture, a scrub cart comprising a support, rollers on the bottom of said support,V ay brakepmeans on the bottom of the support for locking the 'r cart in a given position, said means comprising an eccentrically mounted brake disk, a lever foractuatingsaiddisk and stops for limiting the movement of the lever. l
