2 Claims. (Cl. 15-179) This invention relates to wire brush mountings and in particular to the method of assembling the wire brush with the mountings.
An important object of the invention is to provide means whereby a brush may be clamped between a pair of flanged mountings in such a manner as to be irremovable, except by destroying the mountings.
Another object of the present invention is to provide a connecting means between the flanged mountings which acts as a bearing for the brush and also as a clamping means for both mountings.
Other objects and advantages may be noted from the following specifications and their'accompanying illustration, in which:-
Fig. 1 is perspective view of a brush secured between a pair of mountings.
Fig. 2 is a sectional view of the device.
Fig. 3 is an enlarged fragmentary view of the device showing one of the flanged mountings and the method of securing the sleeve to the mounting.
Fig. 4 is a plan view of the mounting and the sleeve assembly.
Referring more particularly to the drawing, I0 indicates an annular mounting plate anged inwardly at II and again embossed inwardly at I 2, the surface of flange I2 forming a bearing 30 surface for the brush when in use, as when the brush is mounted on a rotary shaft.
Between the mounting. or side plates I0 is attached a connecting member in the form of a sleeve, the edges of which are contracted or bent inwardly as shown at I4 and I5 to contact the embossed portions II of the respective mounting plates I0. This connecting sleeve forms a bearing surface I3 to accommodate the brush I6, said brush being superimposed over the connecting sleeve, after which the second mounting plate is pressed or inserted in the opening I 'I of the sleeve I3, thus confining and clamp- 5 ing the brush in its assembled form.
After the brush is thus assembled an expanding tool of a proper kind (notishown) is inserted in the embossed portion I I of the plates I0 and expanded. This expands the metal, 10 forming a series of struck up or beaded portions I8 around the diameter of the embossed portion II of the mounting I0, and the metal thus expanded forms a locking means for the sleeve I3 and thus locks the brush in the assembled posi- 15 tion.
It will thus be seen that I have provided a very simple, quick and convenient ineans for clamping a brush in a mounting, andthe mounting is so constructed that it is practically im- 20 possible for it to separate, and thus the brush is positively clamped in position.
1. A brush comprising a pair of side plates,
a boss on the inner side of each side plate, said g5 boss having a central opening and an inwardly projecting circular flange aroundsaid opening, forming a bearing, a sleeve between the plates, said sleeve having inturned ends rigidly engaged with the periphery of the boss, and brush material clamped between theplates.
2. A brush as in claim 1, the periphery of the boss having beaded portions in locking engagement with the inturned ends of the sleeve and serving to hold the side plates clamped against the brush. material.
