STREET SWEEPER BRUSH AND HOLDER Filed April 22, 1955 3 Sheets-Sheet 3 United States Patent 2,864,112 p Y STREET swEEPER BRUSH HOLDER Albert Theodore Nielsen, Kolding, Denmark, assignor to Newark Brush Company, Kenilworth, N. J.
Application April 22, 1955, Serial No. 508,137 4 Claims. (Cl. 15--181) This invention relates to a new type of a roller brush structure especially adapted for street sweeping wherein the brush structure is suitably positioned and attached to a truck or tractor.
In the past certain types of roller brushes have been constructed and utilized, for example, cylindrical body of wood has been used having a plurality of holes drilled therein and brush material inserted into the holes and held therein by various types of pitch sticking material. Another type of roller has been utilized and is made of wooden boards fastened to a metallic framework, the boards being drilled through preferably at a slant with a plurality of holes into which brush material is pushed into or through by hand, the same as an ordinary pushbroom. In another construction the holes in the boards are filled with different types o-f round steel wire bent into hairpin shape and pushed through the holes in the boards from the inner sides thereof, usually a metal plate is placed over the inner end of the bunches of Wire and fastened by screws or bolts to the boards. These and other somewhat similar ways have been utilized in the past for making these roller sweepers. I have found that they do not do a satisfactory sweeping job especially after being in use a short time.
It is therefore the principal object of my present invention to provide a construction that can be easily made and one that has a framework that will last a long time and a framework on which the old brush units may be easily removed and new brush units added thereto.
My new and highly useful structure will best be underst-ood and appreciated by reference to the annexed drawings and description thereof. In the drawings:
Figure l is a side View of a complete brush structure with the central brush portion being removed.
Figure 2 s a view similar to Figure 1 with the brush units being shown in central frame construction for carrying the brush units.
Figure 3 is a view of the brush unit framework shown in Figure 2 without the driving means.
Figure 4 is a part sectional and 4part elevational View of the right hand end of Figures l and 2.
Figure 5 is a partial view on the line 5`5 of Figure 4. Figure 6 is a View similar to Figure 4 but with the structure angularly turned to a different position.
Figure 7 is a partial view on the line 7-7 of Figure 6.
Figure 8 is a view on the line 8 8 of Figure 6.
Figure 9 is a partial view of one of the brush units showing the stop pin which is carried by each of the brush holder rings.
Figure 10 is a plan view of one of the spacers used between each of the brush units.
Figure l1 is a view at right angles of Figure 10.
In the various views wherein like numbers refer to corresponding parts, the framework F is composed of a plurality of very strong tubes T,` four being shown, of suitable preferably rust proof material, such as stainless steel. The entire framework F may be considered as being divided into sections by spacing discs 5 that are welded to dotted lines so as to illustrate the r ceY the said tubes. The two end discs or support plates 6 and 7 are identical but are much heavier and stronger than the intermediate plates 5 and are provided with threaded holes 8, four being shown in each of the discs 6 and 7, so suitable metal flanged caps 9 may be fastened to the end plates 6 and 7. Carried by the plates 6 and 7 is a centrally located tube l0, the outer ends of which are welded to the plates 6 and 7. The tube 10 is adapted to receive a drive shaft or, as sho-wn, a pair of stub shafts 12 one at each end. These stub shafts 12 each has a gear wheel 13 fastened thereto by screws 14 that go into the holes 8 in plates 6 and 7 whereby the structure can be readily taken apart to put on new brush units. These brush units B are assembled in suitable holders 15 which normally are U shaped to receive the brush ends, after which the holder is inwardly crimped as shown in Figure 6. The width of the holders 15 is dependent on the density and composition of the brush material being used for different kind of sweepings. Furthermore, the holders 15 are all provided with a series of radial depressions 20 ou both sides of the holder, so the brush material per se appears to be divided into small bundles near the center. This construction prevents the brush material from sliding in the holder 15. One advantage of securing brush material in this manner is that it is possible to use round crimped steel wire instead of flat wire and a more satisfactory sweeping action is obtained. I have also found that this new construction as described causes less wear on the mechanical parts of the general apparatus with which it is used. The holders 15 are held in position on the tube 1 by spacing members 16 which also act as cooling members. Each of the brush holders or rings 15 carries a stop pin 17 which is adapted to engage some of the tubes 1 in either direction of rotation of the brush structure and to thereby get and take up motion from the drive gears 13 simultaneously, which motion is taken up by all the brush units by their stop pins 17.
The ends of the stub shaft 12 are carried by bearings 18 and 19 which may be of any suitable type. It will be obvious that many of the details may be varied without departing from the spirit of this invention and the scope of the appended claims.
While I have shown the central member 10 of the structure as of suitable round pipe, I may use in its place a square section of pipe, which can be readily made from two pieces of angle iron welded together, the dimensions of the angle irons being such as to allow ease of assembly of dri-ving gears.
Having thus described my invention, what I claim is:
1. A street sweeper brush structure of the character described comprising a centrally located operating member carrying brush units, each of which has a stop pin,
said member being composed of a plurality of strong metallic members in the form of seamless pipes suitably and arcuately spaced by longitudinally arranged support plates securely anchored thereto and at least one at each end of said members, the support plates at the ends having a bearing member detachably fastened thereto, a drive shaft and gear carried by each of saidV bearing members and assembly spacing members in the form of channel shaped rings positioned ar-ound said metallic members for properly locating the brush units thereon.
2. A street sweeper brush structure having a centrally located operating member to receive a plurality of brush units, said operating member being composed of a strong member preferably in the form of a pipe located on the axis of the rotating structure and a plurality of longitudinally extending strong metallic parts arcuately spaced from the axis member and anchored at their opposite ends to rigidly stilf plates, each of which has a driving gear fastened thereto, each of said gears having a stub shaft extending on both sides thereof, one extension tting snugly into one end of said axis located member, while the other end is adapted to it into a suitable operating bearing, each brush unit having an annular brush ,holder member U-shaped in cross-section to receive the brush material, the arms of the U being forced inwardly to securely grip the brush material and circular channel shaped members separating the said members that receive the brush material and acting onsaid arms to holdI the brush material in full operative position said last mentioned member Fitting snugly over the parts anchored to the said end plates.
3. A street sweeper brush structure asset forth inclaim 2 further dened in that a angedV cap is used at each end of the structure to act as spacers between the drive gears and the brush units.
4. A street sweeper brush structure as set forthV in claim 2 further defined in that a plurality of circular and arcuately positioned members,
discs are anchored to all of said longitudinally extending between said stiff end plates, and further dened in that the brush holder member is provided with a series of radial depressions on both sides.
