The present invention relates to a brush and consists in providing a ring of sheet iron rolled in a single piece to receive the prepared ring of bristles after which the sides of the ring are 5 compressed together, and for holding said ring together with the ring of bristles a groove is provided in both sides and the outer edge, with inwardly extending depressions, all for the purpose of preventing the material of l0 the ring of bristles from moving longitudinally when in use, between opposites sides of the ring.
In this manner there is obtained a brush of the greatest durability for use for various industrial purposes since it entirely prevents the bristles from coming loose, as they are all seated as though they were made integrally with the rings, thus giving a most secure and durable construction.
In order to fasten brushes of these types upon securing means, there is provided a pin or tenon. set into or secured to the ring. which extends against, or even into, cooperating devices on the holding means.
Metallic wire rings are secured in that the ends of the metal wire are joined in the rings and the ring is held and bent over on every side. and thereby serves'for securing itto the fastening device.
3 on the drawings-f Fig. 1 is a view of a brush from one side;
Fig. la 'is a developed section of a sector of the brush taken as indicated by the line A-A and the arrows, Fig. 1:
Fig. 2 a perpendicular cross section on a larger scale of the lowermost portion of the ring for pressing together; v v
Fig. 3 the same after ithas been pressed together; l
40 Fig. 4 a metal wire brush seen from one side:
Fig. 5 a perpendicular cross section on a larger scale through the lowermost portion of the ring for pressing together; and
Fig. 6 the same after it has been pressed together.
a is a U-shaped ring of band iron rolled in one piece, in which the prepared brush ring b is inset, whereupon the sides of the ring are pressed together and for the utmost securing of the material in the brush ring, is provided on both sides with a groove d and the outer edges with inwardly bent cavitiesl d', which assures that the material of the brush ring cannot move longitudinally when in use, between the inner sides of the ring a.
e is a lug brazed or welded to the inside of ring a which thereby becomes suitable for abutlo ting against, for example, one of aseries of axially directed vanes on the hub f, and thus preventing the brush from rotating upon the hub.
'I'he brush rings are secured upon the hub or mandrel f, which is of length appropriate to 15 the number of rings. 4After being applied, the rings are clamped axially by end washers and nuts in accordance with, the usual practice in the art of assembling section brushes. Such washers or nuts, being conventional, are not zo illustrated.
'I'he hub f as shown in Figs. 1 and 4, comprises a central opening m for a shaft, and is otherwise of cylindrical form, except that in the flgures a double line indicates a iront bevel. Radial 2- vanes lc run the length of the hub in a direction parallel to the axis thereof and serve both as spoke-like supports for the rings a and as stops for the lugs, such as e or i, sol as to carry the brush rings with the rotation of the hub posi- 3o tively.
g, Figs. 4, 5 and 6 indicates the body of kinky wire bristles which may be used in the ring a instead of ilber bristles and held therein by wires h. The wires h encircle the channel of the ring ab a, and the ends of h are twisted and are hooked back as at :i through holes in the bottom of the ring a. Besides securing the wires h. on the bristles, the hooks i also serve as lugs to prevent rotation of the brush on the hub f. o
I claim:
A brush section comprising in combination a ring of U-shaped cross section, bristles therein, and holding elements retaining said bristles in place. portions of said holding elements projecting inwardly through the bottom of said channel.
