Application filed May 8, 1918. Serial No. 233,237.

To all whom it may concern:

Be it known that 'L'CHESLEY T. SMA LL, a citizen of the United States 0'f AIne1'lCa, residing at the city of St. Louis, State of Missouri, United States of America, have inventeda certain new. and useful Can- Brushing Machine, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to \vhich it .ppertainsdomake and use the same, reference bein had to; the accompanying drawings, forming part'of this specification. I

My invention relates to a can brushing machine, and more particularly to one which is adapted to beapplied to the conveyer of a can filling machine. j s In the accompanying drawings, which illustrate one form of; can brushing machine made in accordance with my invention, together with a portion of the conveyer of a can filling machine, to which the same is applied, Figure l is a top plan view, partly in section; Fig. 2 is a side View; Fig. 3 is an'enlarged section taken on the line 33 of Fig. 1; Fig. dis a diagram illustrating the action of the brushes; and Fig. 5 is an enlarged section takenon the line55 ofFig. f

10 indicatesithe T-rails of the ,conveyer of a can filling machine. These T-rails 10 are provided with slots in which travel chains 11, the cans be'ingcarried upon the upper surfaces of said chains. Passing through the are rods 12, upon which are car- T-rails l0 riedbrackets 13, supporting a, guide-rail 14, for guiding the cans traveling upon the chains 11. All of the above described parts are like those shown and, described in my prior application'for'patent for a can filling m'achine, Serial-No. 184,990, filed August 11,1917, and form no part of the pres ent invention, except in combination with the parts hereinafter to be describe 15 are side frames, each of which is pro vided with a pair of hubs 16, passing around the cross rods 12, hereinbefore described. The frames can be adjusted toward and away from the conveyor, and are held in position by means of set screws 17. 18 are vertical spindles carried in roller bearings 19 (Figs. 3 and 5) which bearings are con tained in brackets 20, secured to the said frames 15. The number 0% spindles 18 may be varied to meet the requirements of the machine. In the drawings I have shown a set of three spindles, as carried by each of the side frames 15. Mounted on each of the spindles 18 are a number of brush members 21, each of which is provided with one or more annular rows of bristle tufts The brush members 21 are secured to the spindles 18 by means of set screws 23, as

shown in Fig. 3 of the drawings. By loosening the set screws 23 some elf the brush members 21 may be removed, or more brush members may be added, so as to adapt the ma chine to cans of varying heights. These set screws 23 also permit the brush member 21 to be relatively adjustedaround the spindles 18,so that the vertical rows of bristle tufts 22 maybe brought into alinement, as shown in Fig. 2 of the drawings, or the tufts of the various brush members may be staggered or otherwise relatively placedso as to securethe best results upon the particular kind of cans upon which the machine is to operate.

In order to avoid any interference with the action of the bristles upon the cans throughout their entire length, I remove a portion of each of the guide rails 14 adjacent -to the frames 15 and secure across the spaces thus formed a thin guide rail 24:, which is adapted to pass between two of the annular rows of bristle tufts without interferingwith the action of the brushes, as best s'hown'in Fig. 3 of the drawings. In order to rotate the spindles 18 I provide each of said spindles with a pulley 25. Two of the spindles are also provided with a second pulley26. -'The pulleys 25 of the middle and last spindle 18 are surrounded by a belt 27, while the pulleys 26 of the middleand-first spindle are surrounded b a similar belt 28. The pulleys 25 of the rst spindles are'driven bymeans of belts 29 which pass around pulleys 30 upon a cross shaft 31, upon which is mounted a driving pulley 32, by means of which the machine is driven from any suitable source of power. As the spindles 18 are vertical and the shaft 31 is horizontal, the belts 29 are quartered, and this together with the fact that it is desirable to adjust the frames 15 toward and away from the conveyer without disturbing the pulleys 30, requires the use of a round flexible belt for driving the pulleys 25. In order to secure' this result I form the belt 29 of a coil of spring wire. The

belts

27 and 28 may also be formed of similar coils of spring wire, this, however, is not essential, and any ordinary form of belting may be used for these

belts

27 and 28.

The individual bristle tufts 22 of each annular row are arranged in juxtaposition around the periphery of the brush members 21, but are normally out of contact, as shown in Fig. 1 of the drawings, and diagramarrows A in Fig. l.

tufts 22 upon the cans inatically in Fig. 4. The belts 29 are so arranged as to drive the brush members 21 in the same direction as indicated .by the The action of the bristle 33 is such as to rotate them in the direction indicated by the arrow B of said figure as the said cans are carried \forward in the direction indicated by the arrows C on the conveyer chains 11. This rotation of the cans between the brushes allows the cans to be acted on throughout their entire periphery, thus removing all the dust and particles of powder which adhere to the cans after coming from the filling machine. The individual bristle tufts 22 when brought into contact with the periphery of the cans are bent back, as indicated at D. After moving out of contact with the surfaces of the can each bristle tuft springs forward and strikes with considerable force against the preceding tuft, as indicated at E. This action frees the bristle tufts of the adhering particles of dust or powder.

Having fully described my invention, what I claim as new and desireto secure by Letters Patent of the United States is:

1. In a can brushing machine, the combination with a traveling conveyer for the cans, guiding means for positioning the cans on said conveyer, of a pair of brushes, one situated at each side of the conveyer, means for independently adjusting each of said brushes toward and away from said conveyer, and means for rotating said brushes in the same direction, whereby the cans are rotated on the conveyer as they pass between said brushes.

2. In a can brushing machine, the combination with a traveling conveyer for the cans, of a pair of vertical spindles, one sit- V uated at each side of the conveyer, each of said spindles having mounted thereon brushes comprising a plurahty of remov- Gopies of this patent may be obtained for rotated on the conveyer as bination with a traveling conveyer able brush members, whereby the machine may be adapted to cans of varying heights,

and means for rotating said brushes in the same direction, whereby the cans are they pass between said brushes.

3. In a can brushing machine, the combination with a traveling conveyer for the cans, of a pair of vertical spindles, one situated at each side of said conveyer, each of said spindles having mounted thereon a brush comprising a plurality of members, means for relatively adjusting the brush members around their axis of rotation, and means-for rotating said brushes in the same direction, whereby the cans are rotated on said conveyer as. they pass between said brushes. I

4. In a can brushing machine,

for the cans, of a pair of frames, one arranged at each side of said conveyer, means for adjusting said frames toward and away from said conveyer, vertical spindles carried by said frames and provided with pulleys, brushes carried by said spindles, a driving shaft provided with pulleys, and elastic belts connecting the pulleys on said driving shaft with the pulley on-a pair of said spindles. I

5. In a can brushing machine, the combination with a rail forming a support for a traveling conveyer, of a pair of cross rods carried by saidrail, a pair of guide rails supported from said cross rods, a pair of frames supported on said cross rods and provided with rotary brushes, and means for driving said brushes.

6. In a can brushing machine, the combination with a rail supporting a traveling conveyer, of a pair of cross rods carried by said rail, guide rails supported from said cross rods,
