Definitions

To all whom it mg concem:
Be it knownthat I, Gnome F. Ec1m1rr, a citizen of the United States, residing at Covington, in the county of Kenton and State of Kentucky, have invented a new and useful Improvement in Rota Brushes, of which the following is a speci cation. This invention relates to rotary brushes.
It is an object of the invention to provide a rotary brush which has a scraping action rather than the scratching action which is accomplished by the usual wire rotary brush. This brush is particularly intended for use in the tobacco industry for stripping the last shreds of a tobacco leaf from its long central stem. For such a purpose it is essential that the leaf be removed in as large strips as possible as the value of these strippings depends very largely upon their size.
Another object is to provide a brush in which the scraping elements will not have a tendency to mat or to retain therein shreds of the tobacco or other substance upon which the brush is being used.
These and other objects as will appear are accomplished by this invention which is fully described in the following specification and shown in the accompanying drawing in which Figure 1 is a partial longitudinal section through a brush embodying the invention; Figure 2 is a similar view of the opposite end of the brush with the central sleeve in elevation, Figure 3'--is a front elevation of a brush element as it comes from the dies; Figure 4 is the same but showing the fingers bent at right angles; Figure 5 is a section on the line 5--5 of Figure 2; Figure 6 is similar to Figure 1 but showing a modified form of brush; Figures 7 and 8 are similar to Figures 3 and 4 but showing a modified form of brush element.
In the embodiment illustrated, the rotary .brush is made up upon a sleeve 10 which is secured to a shaft 11 in any suitable manner,
as by means of a bolt 12, so as to be readily removable therefrom. The sleeve 10 is threaded at each end to receive the nut 13 and the lock nut 14.
The sleeve 10 also has a series of external grooves 15 therein, which as shown are four in number which are equally spaced about the sleeve.
A series of brush elements 16 as shown in Figures 3 and 4-. have central openings which permit them to be placed over the sleeve and a series of four inwardly projecting ears 17 each ofwhich is adapted to engage one ofthe spiral rooves 15 of the sleeve 10.
These brus elements are preferably made of steel which after being stamped and bent 'ments 16 in such a way as to be supported by those elements and particularly by the spadelike tips These bristles may be carried 1n any desired way such as in openings 22 in the spacer23. One of the great objections to the use of rotary'brushes having bristles made of spring metal wire is that the bristles bend over and mash down. With these bristles, however, supported and reinforced by the spring sheet metal blade, this difficulty is largely overcome and a brush is proyifded which will have a very much longer form ofbrush element 16 having straight fingers 18. This brush is preferable for some forms of work.
While I have shown and described but a few forms of my rotary brush, it will be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made which do not depart from the spirit and scope of the invention as disclosed in the appended claims, in-which it is my intention to cover all novelty inherent in the invention as broadly as possible in view of the prior art.
What I claim as new and desire to secure by Letters Patent is: Y
1. In a rotary brush, a sleeve, a plurality of sheet metal brush elements on said sleeve each element having a series of radial fingers bent at right angles to the body of said element, spacers for said elements and means for clamping said elements longitudinally of the sleeve.
2. In a rotary brush, a sleeve, a plurality In Figures 7 and 8 is shown a modified.
of sheet metal brush elements on said sleeve, each element having a series of radial fingers bent at right angles to the body of said element, a spiral groove on said sleeve, ears in said elements for engaging said groove, spacers for said elements and means for clamping said elements longitudinally of the sleeve.
3. In a rotary brush, a sleeve, a plurality of sheet metal brush elements on said sleeve, each element having a series of radial fingers bent at right angles to the body of said element, spacers for said elements, means for clamping said elements longitudinally of the sleeve, and radial wire brush elements between said sheet metal brush elements and reinforced thereby.
4. ln a rotary brush, a sleeve, a plurality of sheet metal brush elements on said sleeve, each element having a series of radial fingers having spade like tips bent at right angles to the body of said element, spacers for said elements and means for clamping said elements longitudinally of the sleeve.
5. A sheet metal brush element for rotary brushes having a flat metal body, an opening therein and a lurality of arms radiating from said bodgl the outer endsof which are bent at right angles to the plane of the body.
6. A sheet metal brush element for rotary brushes having a fiat metal body, a central opening in said body, a plurality of arms radiating from said body and having pointed tips which are bent at right angles to the plane of the center.
7. In a rotary brush, a plurality of sheet metal brush elements having flat bodies and openings therein, a spacer between each pair of adjacent elements, a sleeve passin through said elements and spacers, eac element having a series of radial fingers bent at right angles to the body of said element, each finger terminating in a spade-like tip, the tipsof one element overlapping the tips of the adjacent element, and means for clamping said elements longitudinally of the sleeve, whereby a notched space is formed between the tips of adjacent elements.
