BRUSH ASSEMBLY Filed Nov; 14, 1959 INVENTOR. IL/EZMAA/ ,4, STE/E277 1 ATTORNEY.
Patented May 19, 1942 2,283,293 1 Bausn ssam? Herman A; Steicrt, New Centerville, Pa. Application November 14., 1939, Serial No. 304,298
4 Claims.
effective ends of some of the bristles are disposed exteriorly of the periphery of the brush head. This invention is made with such an arrangement particularly in mind, because the foremost objective in view is the provision of a novel arrangement of assembling the bristles in a brush head which readily adapts itself to this angular disposition of the bristles.
The bristles of brushes of the type with which this invention is concerned, such as street cleaning brushes, ordinarily are made from appropriate metal such as steel. The heads with which they are assembled generally are of a multiple part construction consisting of a main body part to which is clamped one or more bristle carrying parts.
Heretofore it has been the practice to form one of the bristle carrying head parts with apertures designed to have the bristles passed therethrough. A single piece of steel wire is bent into hairpin formation and the legs thereof passed through a pair of these apertures, the bend of the hairpin being clamped between the bristle, carrying and main body parts. This known arrangement presents certain disadvantages'which are intended to be obviated by the present invention.
In the first place, considerable difficulty is experienced in assembling the bristles in that each bristle must be threaded through its required opening. Furthermore, the bend of each pair of bristles has been found to be an undesirable factor when subject to the clamping between the parts of the brush head. Perhaps the greatest difiiculty has been experienced in replacing worn bristles.
With the above noted conditions in mind this invention has in View, as an important object, the provision of a brush assembly of the character above noted in which each of the bristle carrying parts of the brush head is formed with a plurality of openings each-of which is designed to receivea unit of bristles. Each bristle unit consists of a plurality of metallic bristles which arrangement in which each opening in the bristlecarrying part of the brush head is surrounded by a countersink that is designed to receive the head of each bristle unit. The openings in the bristle carrying part may be disposed at an appropriate angle for causing the bristles to project therefrom at the required angle with respect to the brush head. Each bristle unit comprises a washer formed with a central opening in whichextrernities of the bristles are received. The bristles are joined to this washer at the required angle, as by welding. Thus when the heads of the bristle units are positioned in the countersinks the bristle carrying parts of the brush headmay be securely clamped to the main body part of the brush head to provide a firm anchorage of the bristle units therein.
Various other more detailed objects and advantages of'the invention will in part become apparent, and in part be hereinafter stated, as the description of the invention proceeds.
The invention, therefore, comprises a brush assembly consisting of a brush head made up of a main body part and one or more bristle carrying parts, together with means for clamping the bristle carrying parts to the main body part. The bristle carrying parts are formed with angularly disposed openings extending therethrough, .and which openings terminate in countersinks on the inner face of the brush part. Assembled in each opening is a bristle unit comprising a plurality of bristles that are welded together and to a washer-like head. This head is received in the countersink, while the bristles extend through the opening in the bristle carrying part.
For a full and more complete understanding of the invention reference may be had to the following' description and accompanying drawing, wherein- Figure 1 is a perspective view of a bristle carrying part of the brush head with certain of the bristle units assembled therein. This View also develops the means for clamping this part to the main body part of the brush head,
Figure 2 is a side View, partly in section, of one end of a bristle unit developing the manner in which the bristles are joined to the head of the bristle unit,
Figure 3 is an elevational showing taken as a section through one of the bristle carrying parts of the brush head, and
Figure 4 is a side elevational showing of a brush assembly in which the bristles are anchored therein in accordance with the precepts of this invention. In this View each bristle unit is represented diagrammatically.
Referring now to the drawing, wherein like reference characters denote corresponding parts,
and first more particularly to Figure 4, a-brush assembly is shown as comprising a brush head referred to in its entirety by the reference character H, which carries a plurality of bristle units each of which is referred to in its entirety by the reference character U.
The brush head H comprises a main body part which is carried at one end of a shaft II which rotates when the brush is used. This main body part II] is formed with a plurality of openings l2, which may be threaded for a purpose to be hereinafter pointed out. Carried on the lower face of the main body part ID are a plurality of bristle carrying head parts 13. Each of these head parts 13 is formed with a required number of openings l4 through-which fastening means, such as headed bolts l5, pass. These bolts l5 are threaded, as shown at It, and these threaded ends I6 are designed to be screwed into the threaded openings l2 in the main body part It] to clamp each of the bristle carrying parts [3 thereto. As shown more particularly in Figure 3, each of the bristle carrying parts I3 is cut away adjacent to the openings M to accommodate the heads of the bolts l5.
Referring now more particularly to Figures 1 and 3, each of the bristle carrying parts l3 is shown as formed with a plurality of apertures or passageways I! which are angularly disposed with respect to the faces of the bristle carrying part l3. The upper face of each bristle carrying part I3 is designed for engagement with the main body part ID of the brush head, and is designated [8. This face 18 is formed with a plurality of countersinks each of which is positioned at the upper extremity of the aperture l'l, these countersinks being designated I9.
One of the bristle units U comprises a plurality of bristles 20 which preferably are made from a steel wire of appropriate cross section such as a flat steel wire. These bristles 20 are closely bunched at one end and received in an opening 2| (see Figure 2) which is formed with a washerlike head 22. With the ends of the bristles so bunched and received in the openings 2| an appropriate metal fusion process, such as welding, is availed of to join the various bristle ends together and to the head 22, the welded joint being shown at 23.
Each of the washer-like heads 22 is designed to be snugly received in one of the countersinks I9, and in joining the washer-like head 22 to the bristles an angular relation between the two will be established that corresponds to the angular disposition of the aperture I! with respect to the faces of the bristle carrying part 13. Each bristle unit is positioned so that the bristles 2|] extend through the apertures I! with the washer-like heads 22 received in the countersinks H3. The bristle carrying part I3 is then assembled with the main body part so that the face l8 contacts the latter. The bolts l5 are then tightened in the manner above described to complete the assembled relationship in which a firm anchorage for each bristle unit is provided.
When it becomes necessary to replace any bristle unit it is obvious that the replacement may be readily carried out by removing the part l3 which carries the worn bristle unit, removing the latter therefrom by merely withdrawing the head 22 from the countersink I9, and drawing the bristles upwardly through the apertures 11.
A new bristle unit may then be positioned in the manner above described and the part l3 again clamped to the main body part 10 of the brush head.
While a preferred specific embodiment of the invention is hereinbefore set forth it is to be clearly understood that the invention is not to be limited to the exact construction illustrated and described, because various modifications of these details may be provided in putting the invention into practice within the purview of the appended claims.
