ROTARY Specification of Letters Patent.

BRUSH.

Patented May 19, 1908.

Application filed February 17, 1908. Serial No. 416,281.

To all whom 'it may concern. l

Be it known that we, MAX STOERR and l MAX` KUETTNER, both subjects of the Emi peror of Germany, and both residing at Oornfort, in the county of Kendall and State of l Texas, have invented certain new and useful l Improvements in Rotary Brushes, of which l the following is a specification.

This invention comprises a novel form of brush of the rotary type, and in accordance with the invention it is proposed to provide a desirable device of this class, operable by a suitable motor7 and in which the various parts are assembled in an advantageous many ner, designed to secure compactness of strucl ture and to economize space.

Other objects of the invention are to employ special mechanism permitting of ready substitution of another brush for that upon the device, to be used for some different purposes, and to embody in the construction of the invention peculiar means for controlling the operation of the brush by the motor.

Other objects and advantages of the presi ent invention will be noted upon reference to l the following detail description, and to the accompanying' drawings, in which:

Figure 1 is a plan view of a brush constructed in accordance with our invention 1 Fig. 2 is a horizontal sectional view; Fig. 3 is a vertical section taken about on the line Fig. 4 is a detail section of the ratchet means cooperating with the spring motor; and Fig. 5 is an end elevation showmodiiied adaptation of the invention.

Similar' reference characters refer to similar parts throughout the description and drawings. y

Specifically describing the invention,'and referring to the drawings, the numeral 1 designates a circular brush which is mounted for rotation upon a head 2 with which is preferably connected a handle 3 The han- 4, this being desirable in order that handles of different lengths may be used in connection with the brush, dependent upon the particular use for which the device is to be employed. The brush 1 is mounted upon the head 2 in a peculiar manner. The head 2 comprises a tubular orhollow body adapted to receive at its ends spindles 5 of end members or sections which are directly connected with the body of the brush.

The end members are indicated 6 and 7,

the member 6 being formed with an integr-al socket 8 which is adapted to be received easily in a recess 9 provided in one end of the body of the brush 1. In like manner, the end member 7 is connected with a small U shaped frame 10, secured thereto by the threaded connection 11, said frame being received in a recess 12 formed in the end of the brush body opposite that having the recess 9. The outer end of the recess 12 is closed by a plate 13 secured by fastening means to the frame 10.

Broadly speaking the head 2 carries end sections or

members

6 and 7, and the latter carry supporting members, 8 and 10, which are connected at opposite ends of the brush body in such a way as to permit ready rotation of the brush when operated in a manner to be described. The supporting member or socket 8 receives a spring motor consisting of a drum or casing 14 in which is arranged a spring 15 connected with a shaft 16. The shaft 16 is a two-part shaft composed of the part 16a secured to the spring motor, and the part 16b secured to the frame 10, which frame supports governor mechanism coacting with the motor. The inner ends of the two parts of the shaft 16 are received in an opening through the body of the brush 1 and the meeting extremities of said parts interlock at 17 to establish a driving connection therebetween. The opening in the brush body which receives the end of the shaft elements is preferably of oblong formation to conform to a similar formation of the shaft, and the brush is thus connected with the shaft in such a manner as to rotate therewith. A ratchet wheel 18 is applied to the casing 14 and a pawl 19 coacts therewith to prevent unwinding of the spring 15 except when the shaft connected therewith rotates. The spring motor is wound up in an obvious way by turning of the handle 2() attached to the casing 14.

To the outer end of shaft part 16b is attached a gear 21 in mesh with pinion 22 mounted on a governor shaft 23. A small fan governor 24 is carried by the shaft 23 and is of course operated by the motor when the brush 1 is rotated. A sliding pin 25 mounted on the frame 10 and plate 13 constituted means arranged to engage the member 24 in order to control the operation of the motor, so that the latter may be stopped or started at will.

A suitable cleaning comb is provided for the brush and is indicated at 26. The device 26 embodies teeth arranged to engage the fibers of the brushto accomplish the desired result. Fastening members 27 are employed to secure the cleaner 26 and body of the head 2 to the

end members

6 and 7. Said members 27 consisting of thumb screws passing through the tubular body of the head 2 and engaging the spindles 5 of the

members

6 and 7 so as to detachably secure the said members in position.

It is contemplated to use different brushes in connection with the supporting and operating mechanism above described and hence it is necessary and desirable that a brush may be quickly removed from, or attached to the supporting means. One brush may be used for cleaning carpets, another for the purpose of the bath, another for cleaning shoes, and others for different purposes, as will be readily appreciated. To remove the brush l it is only necessary to unscrew the fastenings 27 and separate the

end members

6 and 7 by outward movement thereof until the shaft parts, and supporting

devices

10 and 8 are disengaged froml the body of the brush. A different brush may then be quickly substituted for that removed and the

arts

6 and 7 with members carried thereby fbrced together until properly positioned with res ect to one another so as to support the brus in/a manner in which it may Abe readily operated.

Should it be desired to use the brush for bath purposes mainly, the invention may be supported by a wall, or other support, in the manner shown in Fig. 5 of the drawings, in which instance, the body of the head 2 is engaged with the upper portion of a bracket plate 28 directly secured to the support. The operation of the brush when supported as in Fig. 5 may be readily controlled in an evident manner.

Having thus described the invention, what is claimed as new, is:

l. ln a rotary brush, the combination of a `head embod ing separable supporting members, a brus motor mechanism carried by one of the supporting members aforesaid and governor mechanism carried by the other of said supporting members, and a shaft connected with the brush and comprising parts separable with the supporting members, one art of the shaft being connected to and movable with the motor mechanism while the other part of the shaft is similarly connected with the governor mechanism.

2. In means of the class described, the combination of a brush provided at opposite ends with recesses, a two-part shaft upon which the brush is mounted, motor mechanism in one of the recesses of the brush and connected with one of the parts of the shaft, governor mechanism in the other recess of the brush and connected with the other shaft art, the shaft parts being separable and connected by a driving connection, a head comprising separable end members one of which has connection with the governor mechanism and the other of which is connected with the motor mechanism, and means connecting the end members aforesaid and holding the motor and governor mechanisms in operative relation to the brush.

3. ln a device of the class described, the combination of a head comprising separable members, a shaft mounted upon said members and comprising parts having a driving connection with each other, one part of the shaft being mounted on one member of the head while the other is carried by the other member of the head, motor mechanism operably connected with the shaft, and means connecting the separable members of the head together and normally operatively connecting the parts of the drive shaft.

4. ln a device of the class described, the combination of a circular brush the body of which is provided with recesses in its opposite ends, a supporting head comprising a tubular body and separable end members, spindles projecting from the end members and received in the tubular body of the head, fastenings securing the body and end members of the head together, a spring motor comprising a casing received in one of the recesses of the brush body and a spring in said casing, means connecting the motor mechanism and one end 'member of the head, governor mechanism connected with the other end memberof the head and comprising a frame arranged in the recess of the brush opposite that receiving the motor casing, a two-part shaft passing through the body of the brush and connected for rotation of the latter, a driving connection between the parts of said shaft, one of the shaft parts being connected with the spring motor for operation thereby, the other of said shaft parts being mounted on the frame of the governor mechanism, a governor fan mounted on said frame and operable by the shaft aforesaid, and a member controlling the movement of the fan to stop and start the motor.
