KOIBER &: (10., OF SU'HL IN T'U'RING, GERMANY.
To all whom it may concern:
Be it known that I, EUGEN VAN DEVOORDE, mechanical engineer, a subject of the Emperor of Germany, and residing at Bremen, in the German Empire, have invented certain new and useful Improvements in Rotatable Circular Brushes, of which the following is aspecification.
This invention relates to a rotatable cir cular brush which is especially designed for the cleansing of surfaces, for instance, for,
the scraping off of boiler incrustation, the removal of tightly adherent and hardened layers of rust from painted surfaces such as the outer plating of ships, and the like. The brush for this purpose is not composed of separate flexible bristles or wires, but of stifi? points which may be variously formed.
In accordance with the present invention,
expanded radially by the'centrifugal force,
and will consequently exercise pressure upon the surface to be cleaned which is imparted to the totality of the points by the centrifugal force. In this manner a quiet, uniform operation is secured with the brush and it becomes possible for instance to detach softer coating layers from a harder basal layer without injuriously attacking the surface of the said harder basal layer.
For the better comprehension of the invention, it is illustrated in the accompanying drawing in several constructions.
Figure 1 shows the side elevation of one construction. Fig. 2 shows a vertical section through the center. Fig. 3 shows the collecting ring. Fig. 4 shows the sides. Fig. 5 shows a view from above overthe brush points. Fig. 6 shows a view from above of another construction. Fig. 7 shows an axial section through the construction illustrated in Fig. 6. Fig. 8 shows a view of one of the points. Fig. 9 shows a side elevation of the SLITlB-' Fig. 10 shows a brush of a third con:

axial section. Fig. 14 shows the same construction in transverse section. Fig. 15 shows a. side elevation. Fig. 16- shows a view of a special construction of the points. Fig. 17 shows a fifth modification of the brush in axial section. 'Fig. 18 shows the same modification in transverse section. Flg. 19 shows a view of another modification. Flg. 20 shows the corresponding transverse section thereof. Fig. 21 shows another modification of the brush. Fig. 22 shows the specially'formed points.
The drum-shaped brush holder 1 is made of metal and is provided with cavities in any requisite number, which cavities are distributed uniformly over its periphery. The ring 2 is somewhat wider in diameter than the inner diameter of the drum and is cut through so far that the brushing parts 3 pass through the slot. The brushing parts 3 are stamped out of a single piece of metal provided at the top with points and have at their lower edge a perforation which is so formed that the ring 2 fits into it. The brushing parts 3 are placed in the requisite number separately upon the ring 2 through the slot, are then distributed in the slots of the brush holder 1 and the whole construction driven in, whereupon the brush is ready for operation. As the ring 2 is wider in diameter than the inner width of the drum, it is compressed and the slot is closed. At the same time, the ring 2 presses elastically against the wall of the drum in such a manner that the requisite hold is thereby secured. In the construction illustrated in Figs. 6 to 9, the points 4 are formed plane, while those in Figs. 1 to 5 are formed pointed. The opening 5 of the points 4 by which they are secured upon the ring 2, is made sufliciently large to give the points play in the radial direction. The points can therefore when they encounter an obstacle move radially inward and are only pressed by the centrifugal force outward against the surface to be operated upon. The opening 5 of the points 4 is however in addition made so great that the points can also move or swing in the radial direction. Moreover, the slot 6 arranged in the drum 1 can be made so great for each point,
that the points can possess also a free play in the direction of the rotation, as illustrated at 4 in Fig. 6. In the construction of the rotatable brush illustrated in Figs. 10 to 12, the points 7 are formed in the shape of nails or rivets, and are suspended in openings 8 of the cylindrical hollow body 9, whereby they are retained in the openings by means of the .to this mobility of the points occasioned by the play afforded by the opening 8, they have another relief in the radial direction, which is limited by means of the inner concentric cylinder 11. When a surface is to be worked with the brush, the points consequently can not only move in the direction of the superficies of rotation or in the direction of the axis, but they can also be displaced radially toward the center of the brush. A very extensive adaptability of the points and the elastic application thereof is attained in consequence of the centrifugal force during the operation of the brush.
In the construction illustrated in Figs. 13 and 14:, the points 12 are movably suspended by means of links 13. They can for instance be constructed as illustrated having their links 13 arranged on pivots 15 placed axially on the periphery of the brush cylinder 14. The points 12 can freely displace themselves in the superficies of rotation in the one or the other direction, they are consequently when the brush is in rapid rotation, radially adjusted by means of the centrifugal force and consequently encounter the surface to be operated upon elastically and yieldingly.
In order to hold fast the pivots 15, these maybe secured by a number of rings surrounding the brush cylinder 14 and the pivots 15 may pass through openings in these rings. The rings serve at the same time to maintain a distance apart between the points 12, which can be arranged either separately, or in pairs, or in bunches. The points may also be formed fiat, being composed of strips of sheet metal as shown in Figs. 15 and 16.
In the construction illustrated in Figs. 17 and 18, the points are formed of bunches of steel wire 16 or the like, which are held in the holder 17. Through the loop 18 of the points, there passes a pin 19, which projects at both sides beyond the loop. The body 20 of the brush has an annular free space 21 in which all the points are set side by side. In order to facilitate this setting, the one check is formed as a ring 22 and arranged detachable. The play room 21 is so high that the pins 19 can move freely in the radial direction, likewise, the separate bunches can bend over in the tangential direction by the turning of the pivots 19. I
In the construction illustrated in Figs. 19 and 20, the brush is composed of U-shaped bent points 23, which pass through the openlngs 24 of the flat rings 25. As many of the said rings can be placed side by side as is desirable (see Fig. 20). The points 23 have in their openings 24 a free play in all directlons, so that they may either bend over or may move radially. The points may also be formed of flat metal strips as shown in Figs. 21 and 22. They are then provided at their lower end with a head 27, by aid of which they are secured in the openings 28 of the rings 29. The points may however also be turned 90 as illustrated at 30, so that they do not act with the edge but with the broad side.
I claim 1. A brush, comprising a cylindrical body, and a plurality of scraping members mounted on the body to move radially and swing tangentially to said body.
2. A brush, comprising a cylindrical body having an annular cavity and openings leading from the cavity through the periphery of the body, a plurality of scraping members prQ ecting loosely through the openings into the cavity, whereby they are free to move tangentially to the body, and means for retaming the inner ends of the said members in the cavity so as to permit them to move radially through said openings.
3. A brush, comprising a cylindrical body hav ng an annular cavity and openings in its periphery leading into said cavity, a plurality of scraping members extending loosely through the openings into the cavity, and a retaining member in the cavity and with which the inner ends of each of the scraping members have a sliding connection.
4. A brush comprising a cylindrical body having an annular cavity and openings in its periphery leading to the cavity, a plurality of scraping members extending through the openings into the cavity, the inner ends of the members being provided with openings, 7
and means in the cavity loosely engaging the openings of the said members.
5. A brush comprising a holder having a cavity therein, a split ring located in said cavity, and a scraper plate ,having a slot therein and supported on the said ring.
6. A brush comprising a holder having an annular cavity and openings /-in its periphery leading to the cavity, a ring in the cavity, and slotted scraper plates on the ring, the slot in each plate being longer and broader than the contacting part of said ring.
7. A brush comprising a holder having an annular cavity and a plurality of openings in its periphery leading to the cavity, a ring in the cavity a plurality of scraper plates extending through the openings into the cavity, the inner ends of the plates having slots through which the ring passes, the slots of the plates being longer and broader than the contacting part of the ring and the openings of the holder being of greater diameter than the thickness of the plates.
