SPECIFICATION forming part of Letters Patent No. 393,192, dated November 20, 1888.

Application filed Seplomhcr 7, 1831'. Serial No. 248,099. (No model.)

To all whom it may concern.-

Be it known that 1, Russian]; TTnrYnR, a citizen of the United States, residing at Philadelphia,State of Pennsylvania, have invented a new and useful Improvement in Revolving Brushes, of which the following is a full de scription thereof.

My invention consists in a novel construc tion by which the brush is readily caused to revolve, and by its friction accomplishes the desired result, such as cleaning horses, polislr ing,or any other operation in which a rubbing surface is used.

In the drawings, Figure 1 represents an outside View of one form of my improvement; Fig. 2, a section on lincazrv, Fig. 1. Fig. 3 rep resents a sectional view of one modified form of my improvement, in which the axis of the motor is shown in a vertical position, and the brush is connected at the lower end of and revolves with said axis. Fig. 8.

0 represents the armature, and D the magnets forming an electric motor. The current comes from any desired source through the wires b,whieh are preferably surrounded by an insulating material. The wires are carried through the handle B, and are connected with the frame (1, by means of which the current is carried to the motor. The magnets are insulated from the frame (I by the insulating-surfaces (1 d. The brush-frame a of the brush A is connected with and insulated from-the frame (Z. This brush may be constructed of any material in accordance with the desired use. The brush A being connected with the shaft of the electric motor, when the currentis sentth rough, the motorshaft revolves and the brush is carried around with it, and upon the brush being presented to the surface of the substance to be operated upon its revolution causes it to perform the desired work. If desired, the shaft and armature may be fixed and the magnets revolve, and by their revolution operate the brush; or the magnets may be fixed, andahollow armature revolving about them may be used to operate the brush.

Fig. 4 is aplan view of My invention may be used for polishing surfaces of any character and for performing any work which requires a metallic or other characterofbrusl1,the term brush in this specification and claims, besides its ordinary meaning, being intended to refer to any frictional surface, such as emery-cloth.

If. desired, the frame (I may be made of insulated material. lVhile I consider the con struction as illustrated in the accompanying drawings as desirable forms, yet I do not intend to limit myself to the specific forms so illustrated, as it is obvious that many other specific means of connecting the currentsource with the electric motor may be used, and also various differences of construction may be used without departing from myinvention. I can replace thebristles of the brusn by the use of emery or other frictional surface without departing from the invention.

Having now fully described my invention, what I claini is as follows:

1. In combination, an electric motor, a brush surrounding said motor, a source of electriccurrent supply, and means to connect said electric-current supply with the motor.

2. In combinatioman electric motor, a brush attached to, insulated from, and revolving with said motor, a source of electric-current supply, and means to connect said electriccurreut supply with the motor.

3. In combinatioman clectricmotor, abrush attached to and revolving with said motor, a source ofclectric-currcnt supply, and means to connect said electric-current supply with the motor.

4. In combination,anelcctricmotor,abrush attached to and revolving with said motor, a source of electric-current supply, framed, and handle B, and means to connect the source of clectrie-current supply with the motor, all constructed and operated substantially as and for the purpose specified.
