ROTARY BRUSH.

Specification of Letters Patent.

Application filed October 20, 1915. Serial No. 56,9116.

T0 all whom 'it may concern Be it known that I, RALPH B. GooD'RIoH a citizen of the United States,Av residing atA College Hill, lin the county of Hamilton and State 'of Ohio, have invented certain new and 'useful Improvements in Rotary Brushes, of which the following is a speci'- fication.

This invention relates to a novel improvement in brushing-and scrubbing devices of the type which employ a rotary brush, and which-are particularly adapted for washing automobiles or other vehicles, although susceptible to a wide rangevof other uses.

To this end, the invention contemplates a simple and practical device which utilizes a supply of running water for the two-fold f purpose of rotating the brush element, and

also supplying thereto the necessary water for the washing operation. That is to say, the invention has in- Iview a novel construction whereby the same water which actuates the brush-operating instrumentalities, is fed to the brush without waste or leakage, thereby providing a device of this character that not only economizes the consumption of water but gives a maximum cleaning eiiciency for the water used in a safe and convement manner.'

Another object of the invention 1s to provide a novel brush operating device that 1s easily made 'and assembled, and capable of bei-ng readily taken apart to facilitate repairs and renewals. invention proposes to utilize a special brush which constitutes an essential part of the apparatus, and may be easily and quickly connected or disconnected from the brush4 operatingv deviceA when desired, but when coupled therewith, is positively held orv locked so that all of the power from the operating device is carried direct to the brush.

`A further object of the invention is to provide a novel rotary brush, the body of which is made of a material that will not be affected by the water, and which isso constructed that the same may freely pass from the interior thereof to and through .the bristles to-ass'ist in the cleaning operation. Furthermore, 4it is proposed to make the brush of such a design thatit will readily t into the corners and more or less concealed places usually found on a vehicle.

YWith `the above and otherv objectsin view ywhich will more readily appear as the na-.

In this connection, the

ture of the invention is better understood,

the same consists in the novel'construction,

combination and arrangement of parts here.

inafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the present invention is illustrated in the accompanying drawings, in which.-

Figure l isAa side elevation of` my im` proved rotary brush, and the means for operating the same. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a vertical sectional view. Fig 4 is an enlarged detail elevation of the core ofthe rotary brush, showing the end plug detached. Fig. 5 is a vertical sectional View of the construction shown in Fig. 4 with theend plug in place,

and the bristles shown in Ione lof the chan-- nels. Fig. 6 is an elevation of the rear end of the complete br'ush.

Similar reference characters designate;Y

corresponding parts throughout the several figures of the drawings.

A novel and distinctive feature of the present invention resides in the provision of a suitable casing having at one' side an inlet connection, and an oppositely located outletl extension having'fitted thereto-a rotatable brush. which is capable of distributing the water passing through the casing for the washing operation, after it has operated the brush actuating mechanism.y r

-As will be observed from the several Inigures of the drawings, this casing is -designated generally as C, and essentially comprises the complemental sections 1 and 2 which may 'be secured together by suitable fastening elements 3. Referring to the novel features of construction ofthe casing,

it .will be noted .that the section 1 thereof is provided with an inlet connection 4, while the portion of the section directly opposite this connection is formed with an extended neck portion a which together with a correeoy sponding neck portion 'b of the complemental section 2 providesan outlet extension f 5 having an open discharge -mouth 6. It will thus be apparent that 'water supplied to the casing through the inlet connection 4l will have a vsubstantially direct passage' throughithe same tol exhaust-through the discharge mouth 6. The said outlet extension 5- is provided with an annularflange 7 whichconstitutes an abutment for asuitable 'washer 8, that is intended to protect or.

shield the part of the vehicle being washed from being scratched or marred by the metal casing, but at the same time has another function which will hereinafter more-fully appear. The inlet connection 4 is interiorly threaded as shown in Fig. 2, to detachably receive the threaded end of a hollow'pipe 9 which constitutes a handle for manipulating the present device. This pipe 9 is provided at one end with a suitable coupling member 10 for connecting With a hose or other convenient source of water supply, and is provided at the opposite end with internal threads for receiving the threaded shank 11 of a jet nozzle 12. As Will be clear from Fig. 2, this jet nozzle 12 is located Within the inlet connection 4, and is adapted to direct a jet of Water into the interior of the casing C.

The water fed into the casing by means of the nozzle 12 is adapted to actuate a brush operating motor which is housed and concealed within the casing. This motor essentially comprises a water wheel 13 having a plurality of cuppedimpact blades 14 which are disposed directly in the path of discharge of the jet nozzle v12. The said wheel 13 is carried by a transmission shaft 15 having its opposite ends respectively journaled in the sections 1 and 2, and also carrying a worm 16. In connection with the'end ofthe shaft journaled in the section 2 it will be observed that the same may be provided with a plurality of bearing washers w, and may also be supplied with lubricant from the tube T formed on the exterior of the section by the adjustment of the vscrew S. This arrangement of the shaft 15 causes thesame to be' disposed transversely of the interior ofthe casing, and facilitates the meshing of the Worm 16 carried thereby With a Worm pinion 17 mounted on a motor driven shaft 18. This shaft 18 is carried in suitable brackets 19 formed from the inner side of the section 2, and' is also provided with a shaft casing 20 which not only facilitates the assembling of the device inasmuch as it holds the worm pinion 17 in position, but also protects the said shaft from rust and corro-sion and provides a more substantial and steady bearing therefor.` It will also-be noted that this shaft is disposed longitudinally of the casing, and therefore at right angles to the transmission shaft 15, and is located i'n the center of the outlet eX-v tension 5, and therefore in the direct line' lof discharge' or passage of the water through the casing.

The frontend of the motor shaft 18 is provided with a slot 21 for engaging with the locking plate 22 Whichvi's secured within the hollowconical body of the rotary brush designated inI its entirety by the reference character B. This brush essentially comprises a yhollow perforated conical core 23,

License and is provided at its rear Vend with a suitable spider 24, which is rigidly secured toL issuing from the discharge mouth 6 thereof l flows into the interior of the core, and makes its way to the brush bristles through the plurality of perforations p therein. In this connection it `will also be noted that the spider 24 and locking p late 22 are arranged Within the interior of the core so as to permit the rear end of the core to fit over the end of the extension 5 and abut against the washer 8 which maybe of leather, rubber,`

or any other suitable material, to thus protect the operator by preventing water from splashing back over the casing C.

Referring to the additional features of construction involved in connection with the brush B, particular reference may be made to Figs. 4, 5 and 6. From these figures it will be observed that the hollow core 23 is substantially frusto-conical. That is to say,

the upper end thereof is cut off to provide for receiving an end plug 26, which may be made fast to the core by means of azsuitable fastening element 27 lfitting into the opening 27a. This end plug 26 is provided with a discharge passage 28', and is also provided with a series of spaced annular flanges 29 which gradually diminish in diameter and have therebetween the grooves 30 lwhich are 4connected by means of an oblique slit 31 in the flanges' 29. These grooves 30 are adapted to receive the bristles to form the ends of the brush, and correspond to the continuous channel member 32 on the core. This channel member is spirally wound from one end of the core 23 to the other, and is preferably made of light metal, as is also the core or brush body 23, thus making it possible for sthe channel member to be soldered or otherwise secured to the brush body, in a manner Which will not be affected by the water.

The bristles designated generally as 33 in thebrush B are held in position by means of a retaining Wire 34. That is to say, a single continuous retaining Wire having one end made fast tothe. core, preferably at its bottom end, is wound into the channel, thus pressing the bristles laid across the same into such aJ positibn4 that they stand outwardly from the core body as shown in Fig. 5, and also in Fig. 2. The plug 26 which is fitted in the end of the core or brush body, carries its own bristlesinthel grooves 30 by a separate retainingl wire slmilar to the wire 34 which in practice has one end secured to the shank of the plug and then passes through each groove and to the adjoining one by means of the oblique slots 31. Thus, after 5 the core`23 is'fitted with its bristles, the'endl the Lsaid washer, and means within the casplug may bel placed in position. V

From the foregoing, it will be apparent that water issuing from the jet nozzle 12 will strike against the cupped impact blades 14 of the water wheel13, and thusturn `the worm pinion 17 on the shaft 18 will of course be rotated, thus turning the brush B through the means already described.' Ac-V cordingly, it will be obvious that the'same water which operates the water wheel 13 passes on through the outlet extension 5 of the casing to the vbrush to 'be used in" the washing operation, thus utilizing the water for the two-fold purpose of operating the brush and assisting the same in the cleaning operation.

Without further description, it isv thought that the many features and advantages of the present invention will be readily apparent, and it will also be understood that "changes in the form, proportion, and minor details of construction may be resorted to without departing from .the 'spirit ofthe invention or scope of the appended claims.
