'Joseph Gasser UNITED STATES APATENT Ollllflhlo JOSEPH GASSER, OF TRENTON, NEW JERSEY.

BRUSH.

Application filed August 23, 1918.

To all whom t may concern Be it known that I, JOSEPH GAssnR, a citizen of United States, residing at 27 Carrol street, Trenton, in the -county of Mercer and State of New Jersey, have invented new and useful Improvements in Brushes, of which the following is a specication.

The invention relates to brushing and scrubbing, and more particularly to a device for accomplishing that purpose, and has for an object to provide a rotary brush for use in brushing or scrubbing, and which is particularly adapted for use in cleaning or scrubbingrust from iron or steel.

Although the invention may be adapted for various purposes, I particularly employ my brush for use on the hulls of ships and the like, for removing therefrom any accumulated rust, barnacles, or other foreign matter. To this end I provide a brush body which is preferably arranged with steel bristles, and which is rotated at a high rate of speed, in order to effectively remove any incrustations that may have accumulated on the sides of a ship or on steel plates.

In the further disclosure of the inven tion, reference is to be had to the accompanying drawing, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a side elevation of the brush.

F ig. 2 is an end view.

F ig. 3 is a vertical longitudinal sectional view taken on the line 3 3 in Fig. 2, and

Fig. a is a cross-sectional view taken on the line -a in Fig. 1.

Referring more particularly to the views, the brush indicated in its. entirety by the numeral 10, consists 'essentially of a frame 11, including a casing 12 having a suitable motor 13, seated therein, a handle 14 being provided with a shank 15 having connection between the-handle and the casing, and constituting a part of the frame 11. n the event the motor 13 is an electrical motor, the necessary wires 16 are carried along the shank 15 through the handle 141-, with a suitable switch 17 at a convenient place on the handle, the wires 16 then being carried to a suitable source of electrical energy. Of course it will be understood that I may employ some other form of motor, such as an air-driven motor -audsupply air by means of a suitable pipe or tube (not shown) and which may be carried through the handle Specification of Letters'latent.

yand shank in the same manner as the wires '16. The casing 12 at one end thereof is provided with an opening 1,8, and immediately adjacent the opening within the casing, is disposed one end of the shaft 19 of the motor 13. A brush body 2() consisting of a substantially cylindrical element 21 and bristles 22 secured therein, is disposed so that the body or main part will encircle the motor casing, and the brush body is provided with an indented portion 23, in thev nature of a bearing and which has an opening 2a, through which extends the shaft 19 of they motor, a suitable thumb nut 25 being arranged in the indented portion to engage with the shaft and rigidly clamp the brush body to the motor shaft. With this construction it will be seen that the brush body will in fact be mounted upon the casing as a bearing or support, and will have connection with the shaft of the motor through the medium of the body 21 and thumb nut 25.

Adjacent the inner end of the handle 14 there is provided a shield 26, which is substantially semi-circular in shape and which is suitably secured to the shank 15 to partially encircle the brush body, thus protecting the hand of the operator, which will be clearly seen.

In order that the free end of the brush body, or namely, that part which is nearest to the inner end of the casing, will not bear against the exterior of the casing in the rapid rotation of the brush body, I provide a ring 27, which secured to the inner end of the brush body, tends to aid in properly supporting the brush body upon the casing, and thereby prevents any undue friction of the main part 21 of the brush body with the casing.

With a brush of the character described, it will be clear that the part of the brush opposed to the shield can be brought to bear against the side of a steel plate or the hull of a vessel, and when the switch 17 is operated to close the circuit to the motor, in the event that an electrical motor is employed, the

tor easing Carried by the frame and rigid' With the latter, said motor casing projecting from one side of the frame, a handle on the frame, a brush body loosely encircling the easing` and disposed to one side of the frame, and a segmental shield interposed between the handle and the brush body, said handle being disposedA in ol'set relation to the frame, and lying,` in the central transverse plane of said easing7 brush body and said shield.

In testimony whereofl I aiix my signature.

JOSEPH GASSER.
