rownnornnnrnn CLEANING BRUSH.

Application filed January 16, 1926. Serial No. 81,720.

This invention relates broadly to new and useful improvements in power-operated brushes and has more specific reference to a Water-operated rotary brush.

An important object of the present 1nvention is the provision of arotary brush adapted to be associated with a Water motor of any ordinary or preferred construction, so that the Water used to operate the motor will also be utilized by the brus Another object of the present invention is the provision of new and novel means" for connectingthe brush with the motor, in such a manner that as the Water exhausts from the motor, it Will pass through thebrush and onto the object being cleaned.

Another obj ectof the invention istoprovide' simplified means "for transmitting the rotary, movement from the driving shaft of the motor to the brush.

, Another object is to provide such a brush having associated therewith means for carrying a quantity of soap or the like which 1s adapted to be used during the cleaning poration.

A further object of the invention is the provision ofnew and novel means for mounting the soap carrying means Withm the brush proper so that the exhaust Water fromthe motor will come in contact with the soap as it passesthrough the brushonto the object being Washed,

A still further object is to provide a r0- tary brush of the character stated Which will save both time and labor in'the cleaning of various objects such as the under surfaces of automobile fenders.

A still further object is-to provide such a rotary brush which While simple in its con struction, is nevertheless strong, sturdy and durable, practical and efficient in its operation and an advance in the art.

lVith these and numerous other objects in view, the invention resides-in the novelconstruction, combination and arrangement of partsto hemore fully hereinafter described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims. s a

In the drawings forming a part of this application and wherein similar characters of reference denote corresponding parts throughout the several views: 7

Figure lis a front view of a power-operated brush constructed in accordance with the present invention,

Figure :2 is a side elevation thereof,

Figure 3 is a sectional view substantially on line 3-3 of Figure 1,

Figure 4 is a transverse sectional view on line l-4 of Figure 3,

Figure 5"is a detail view of a slight modification of the present invention showing an additional Way in which a hose may be secured toythe Water inlet port,

Figure 6 is a sectional View on line 6-6'of Figure 5.

Referringmore particularly to the accompanying drawings and more especially to Figures 1 to 4; inclusive, wherein for the purpose of illustration has been disclosed a preferred embodiment of the present invention, the letter A denotesas a Whole, a Water motor which may be of any ordinary or preferred construction and in connection With which the improved rotary brush B is adapted to be associatec lVhile, as stated above, the motor A may be, of any ordinary or preferred construction, the type disclosed herein comprises a' sub stantially circular housing 10 from one point of which extendsthe Water inletport 11' to which is adapted to be secured one end of a suitable Water conductor such as a hose or the like,t-h'e other end of Which may be secured to a suitable source of supply.

Formed onthe periphery of the housing and extending in an opposite direction to the-Water inlet port 11, is the water outlet port 12 having secured thereto one end of the tubular-jcoupling- 13 provided at its opposite end With the bearing sleeve 14 arranged in substantially parallel relation to the Water outletport 12.

Mountedtransversely Within the housing 10 is the usual drive shaft 15 projecting beyond the housing at one side thereof and having fixe'd thereto the Worm gear 16 adapted to remain in constant mesh with the gear 17 positioned at right angles thereto and fixed on the adjacent end of the shaft 18, the

outer end portion of said shaft passing through th'esaid bearing sleeve 14. It will, i

of course, be understood thatthere is mount edon the shaft 15 Within the housing'lO, a plurality of vanes, propeller blades" or the like so that the Waterengaging-therewith will arise the rotation of thesaid shaft Which will be imparted through the gears 16 and 17 to the shaft 18. It is not thought necessary, however, to disclose the construction within the housing inasmuch as it may be of any ordinary or preferred type.

Upon reference to Figure 3, it will be clearly seen that the upper end portion of the shaft 18 is formed with the longitudinally disposed elongated recess 19 and that also formed in the periphery of the shaft and con'inninicating with the recess are a plurality of openings 20, positioned directly opposite the opening in the tubular coupling 13 and adapted for selective registration therewith as the shaft is rotated, whereby to effect communication between the motor and the brush.

The brush B comprises in its construction a plurality of spaced inverted substantially U-shaped wire ribs 21 carrying the bristles 22 secured thereto in any desired manner such as by twisting the wires constituting the ribs around the bristles as disclosed in the drawings. The free ends of the ribs are suitably secured to the annular band 23 which in turn is bolted, as at 24, to the annular flange 25 formed on the periphery of the shaft 18 adjacent its outer end, said flange adapted to abut the enlarged end portion 26 oi? the bearing sleeve 14.

Arranged to be supported within the brush B is an elongated soap container or cage C extending longitudinally thereof, said container being preferably constructed of wire and comprising the four substantially parallel corner wires 27 and the intermediate longitudinal side wires 28, these wires being connected by the inter-woven transversefivires 29. Carried by each of the corner wires adjacent its opposite ends are the wire hooks or clips 30, the free ends of which engage the ribs of the brush as indicated at 31 whereby to securely retain the container in its proper position within the brush.

This container is adapted to carry a quantity of soap or the like and secured to the end thereof adjacent the motor is a conicalshaped deflector 32 provided to spread the water as it enters the brush.

In the operation of the invention, it will readily be seen that as the water enters the housing and through suitable means contained therein causes the rotation of the shaft 15, this rotary movement will be transmitted to the shaft 18 through the worm gears 16 and 17 and inasmuch as the brush is secured to the flange of the shaft, the same will also be caused to, rotate. As the exhaust water passes out of the housing through the outlet port, it will be conducted through the tubular coupling 13, and thence into the brush through the spaced openings 20 and the recess 19 in the said shaft 18. The water engaging with the deflector 32 will be spread in all directions and as the brush continues to rotate, this water will run over and come into contact with the soap or the like within the wire cage C before it passes through the wire ribs of the brush onto the object being cleaned. In this manner, the water as it comes into contact with the object being cleaned will have mixed therewith a quantity of soap whereby to cii'ect the easy cleaning of the object.

In Figures 5 and 6 has been shown another way in which a hose may be secured to the water inlet port of the motor and by reference to these figures, it will be noted that there is provided the motor A comprising a circular housing 10, provided with the water inlet port 11. However, in this term, there is secured to the water inlet port 11, in any suitable manner, such as by means 01? the bolt 3:2, a bracket 33 to the outerend of which is secured the bight portion 31 of the clamp 35 having the arcuately curved resilient arms 36 and 37, the free ends of which are provided with the lugs 38 and 39 through which pass the bolt 40 having threaded upon one end thereof a wing nut or the like -l-l, the portion of the bolt intermediate the said lugs 38 and 39 being encircled by the coil spring 42 which acts to norn'ially urge the spring arms 36 and 37 apart.

The numeral 13 denotes one end of a suitable hose, the other end of which may be attached to the source of water supply in any desired manner. In the application of the clamp, the wing nut 11 is first loosened so that the spring arms will be forced apart by the action of the spring 42 to a degree suliicient to permit the insertion of the hose between the same and the water inlet port, it being of course understood that the hose is slipped over the said inlet port. The wing nut 11 is then subsequently tightened whereupon the spring arms 36 and 37 of the clamp 235 will engage the hose i i and clamp the same tightly onto the utter inlet port 11.

From the above. it will be readily appreciated that there has been provided a new and novel \\'atei.'operated rotary brush which will accomplish all of the objects and perform all of the functions claimed hereinabove. Also. that while there has been illustrated and described a preferred embodiment thereof, it is to be understood, that various changes or IllOCllliCfltlODS in the details of construction may be resorted to without dcparting from or sacrificing the spirit of the invention so long as these modifications or changes fall within the scope of the appended claims.

lVhat is claimed is:

1. A brush head structure designed to have water forced into the interior thereof. comprising a base plate, having a passage therethrough for the extension therethrough ill) of a discharge end of a water pipe and a plurality of inverted substantially U-shapedsaid element, a plurality of inverted substantially U-shaped frames extending outwardly from one face of said plate and having the free ends of their legs secured at diametrically opposite points in the plate, bristle members secured to and projecting outwardly from each of said frames, and a foraminous soap receptacle adapted to be mounted Within said head, said receptacle having an imperforate bottom of 001110211 shape designed to be arranged over said Water CllS- charge element to cause water tobe spread laterally Within the head.

3. In combination, a brush head structure adapted to be revolubly mounted upon a Water discharge element, comprising a base plate body designed to be secured to said element, a plurality of inverted substantially U-shaped frames, extending outwardly from the face of said plate and having the free ends of their legs secured at diametrically opposite points in the plate, bristle members secured to and projecting outwardly from each of said frames, a Wire soap cage structure arranged Within said head, and a plurality of clip members extending from the all of said cage to and engaging said frame legs to suspend said cage in position Within the head.

In testimony whereof I aifix my signature.
