' naar VCTOR A. MILLER, OF ST. PAUL, FHNNESOTA.

RQTARY BRUSH.

`application led July 30,

To all whom. t may concern:

Be it known that l, Vieron A, MILLER, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Rotary Brushes, of which the following is a speciication.

rlhis invention relates to rotary brushes and more particularly to an improved scrubbing and cleaning apparatus of the type which employs a rotary brush.

@ne of the objects oit the invention is to provide an a paratus of this character which will utilize a supply of running water for the purpose of supplying the rota-ry motion to the brush element, and also furnish the necessary water for the cleaning operation.

Another obfject of the invention is to character which will permit the user to edectivelybrush a surface and thoroughly clear the same without splashing or oversupplying the water to the surface which is being cleaned.

Another object is to provide a brush of this character which will haveits mechanism entirely within the control of the operator so that the supply of water and the speed of the brush may be governed during the operation of the same.

Other objects of the invention will apear upon consideration of the following etail description and accompanying drawings, wherein Figure l is a longitudinal horizontal section through the brush constructed in accordance with my invention,

Figure 2 is a longitudinal vertical section,

Figure 3 is a side elevation of the rotor,

Figure 4 is an end elevation of the same,

Figure 5 is a cross section taken on the line 5-5 of Fig. 3,

Figure 6 is a to plan view of the frame structure for holding the brush mechanism,

Figure 7 is a side elevation of the central distributing sleeve, and

Figure 8 is a cross section through the controlling mechanism.

Referring to the drawing by numerals, the body 1 of the brush is constructed to form a suitable tra-me being substantially semi-cylindrical in formation to permit one, half of the brush element to be encased within the trame while the other portion 1921. Serial No. 488,580.

is exposed as shown to advantage in Fig. 2. The enlarged Semi-cylindrical portion 2 1s integrally connected to an extension 3 which is provided with a handle 4 for pei'- mitting convenient manipulation of the brush. The extension 3 is provided with a longitudinal passage-way 5 which communicates with an enlargement 6 on one sideo-i the brush frame, the enlargement being proa bearing for a distributing sleeve 12 which 'i' is centrally located with respect to the centery of the iframe.v rlihis distributing vsleeve 12 consists of a tubular memberhaving a series of openings or perforations 13 therein and one end of the sleeve is provided with a stud end 14 adapted to be extended through the central opening in the hearing member 7 and equipped with a removable nut 15 so as to hold the distributing sleeve 12 in osition. rlhe opposite end of the sleeve is screw threadedly mounted in the opposite side of the frame, and the hollow central portion o the sleeve communicates with the passage-way 5 as shown to ad vantage in Fig. 1.

Mounted for rotary movement upon the sleeve is the rotor 16 which consists of a series of blades or ins 17 arranged in circumferentially spaced relation and having their ends connected to circular end pieces 18 which are equipped with diametricall'yA opposite lugs 19. The brush consists of a brush head to which the bristles are attached, and this brush head comprises two end rings 20 between which channel bars 21 extend, the channel bars being in circumferentially spaced relation and located near the outer peripheries of the end rings 2O so that the bars 21 will be in spaced relation from the rotor 16 as shown to advantage in Fig. 2. The channel bars 21 have .bristles lodged therein, each channel bar beingpro vided with a series of three clusters of bristles, the clusters being separated by spacing members 22 as shown in Fig'. 1. c

channel bar secures the bristles in position iic longitudinally extending rod through Yrea/eh ,y

and it will be obvious that any convenient or desirable form of fastening the bristles in position may be employed. The end rings 20 are each provided with diametrically opposite slots adapted to receive the lugs 19 of the circular end piece 18, so that the brush head, the end piece and rotor 16 are rotated together.

At the diametrically opposite portions of the open side of the frame, the latter'is provided with recesses 23 extending longitudinally of the frame and adapted to receive auxiliary brush members 24 which co-operate to prevent splashing of the water While the brush is in use. These brushes 24 eX- tend tangentially with respect to the brush element so that when the brush element is in operation the water will be confined to the space between the auxiliary brushes 24.

A controlling mechanism shown in Fig. 8 is employed to permit the operator to control the supply of water furnished to the brush. The supply pipe 25 which is in communication with the passage-way 5 extends for any desired length and has attached thereto a handle member 26 which is hollow7 as shown in Fig. 8 and which is provided with an angular partition 27 having a cen-l tral opening 28 normally closed by a spring valve 29. This spring valve is ,controlled by a trigger or finger lever 30 pivotally mounted as indicated at 31 and normally held by a spring 32 to maintain the valve 28 in closed position. The valve may be opened by pulling the trigger or finger lever 30 toward the handle 26 thus lifting the valve against the action of the springV 32. When the trigger. is released the spring will force the valve28 into closed position and thus shut off the water, the movement of the lever 30 being limited by a stop lug 33 on the end of the'lever as shown in Fig. 8'.' Obviously this mechanism will permit the supply of water to be entirely within the control of the operator and the brush may be operated slowly or ata greater rate of speed according to the desire of the user.

Minor changes may be made in the details of construction without departing from the spirit of the invention or the scope of the claims hereunto appended.

What is claimed is 1. In an apparatus of the character described, a frame provided with a supply passage-way, a central distributing sleeve mounted in the frame and having a hollow interior communicating with the pasasgeway, the said sleeve being provided with perforations throughout its length, a rotary member mounted upon the sleeve and including a plurality of circumferentially spaced blades to receive water passing through the openings in the said distributing sleeve and a brush element rotatably mounted in the frame and connected to the said rotary member at the ends thereof whereby the said brush element will be rotated when the rotary member is rotated.

2. An apparatus of the character described comprising a frame provided with a substantially semi-cylindrical body portion and equipped with an extension, a passage-way extending through the extension and leading to one end of the said semicylindrical body portion, a distributing sleeve mounted in the body and having one end in communication with the passageway, a rotary member including longitudinal blades circumferentially spaced apart and embracing the said distributing sleeve7 the latter being provided with openings to establish a water passage between the blades and the interior of the distributing sleeve the .end portions of the rotary member having lugs, a brush head including end rings mounted on the rotary member and connected by the said lugs `to the rotary member whereby the brush element will rotate when the rotary member is operated, the said brush element having circumferentially spaced brush members extending throughout its length.

In testimony whereof I have aiixed my signature in the presence of two witnesses.
