Specification of Letters Patent. Patented July 112, 191W Application filed September 16, 1909. Serial No. 517,993.

To all whom it may concern:

Be it known that I, WILLIAM C. VANNE- MAN, of Anderson, county of Madison, and State of Indiana, have invented a certain new and useful Tin-Plate Polishin and Cleaning Machine; and I do hereby eclare that the following is a full, clear, and exact description thereof, reference bein had to hich like numerals refer to like parts.

The object of this invention is to improve cleaning and polishing tin plates and the like.

One feature of the invention consists in providing a series of rolls through which the tin plates pass horizontally, with means located above the same for depositing bran or other cleaning and polishing material upon the surface of the rolls and the tin plates and providing under the series of rolls a horizontal bottom late on which the bran or cleaning materia accumulates and piles up sufificiently to substantially envelop the lower rolls of the series, the rolls at their ends being mounted in openings in a frame so that there is no box-like receptacle for the bran or cleaning material and no opportunity for such material to enter the bearings of the rolls and interfere with their operation. The pile of bran which accumulates on the bottom plate tapers upwardly at the sides so as to be remote from the bearings of the rolls and yet supplies the lower rolls with material for cleaning and polishing the edge surfaces of the tin plates. Along with the foregoing, means are provided for the vertical adjustment of said bottom bran-holding plate whereby be adjusted in position for maintaining the desired quantity of bran.

Another feature of the invention consists of a provision, in connection with the foregoing bottom plate, of a tapering receiver below the same in which the bran, after passing through the rollers and off the bottom plate, is received and from which it is returned to a point above the rolls for repeated discharge upon the rolls. In connect-ion therewith a novel discharge spout with a plurality of downwardly flaring passageways is provided for distributing the dis charged bran laterallly of the machine, the spout being contracte in the other direction.

Another feature of the invention consists in means for mounting a roll for the discharge of the tinpl'ates from the machine so that said roll ma it may be adjusted vertically and also horizontal y toward or from the other rolls. Along with said roll there is combined a cleaning brush, said brush acting on the up er surface of the lates as they pass over e said discharge r pressure of said brush on the plates is regulated by said adjustment of said roll. Said roll must be adjusted to accommodate itself to tin plates of varying sizes and degrees of stiifness.

The nature of the invention will be understood from the acomp'anying drawings and the following description and claims.

In the drawings there is shown in Figure 1 an elevation of the right hand side of the machine. Fig. 2 is a vertical transverse section on the line 22 of Fig. 1. Fig. 3 is a horizontal section on the line 3 3 of Fig. 2. Fig. 4 is a vertical longitudinal section centrally through the machine with the upper part of the bran conveyer broken away. Fig. 5 is a vertical longitudinal section through part of the machine on the line 5-5 of Fig. 2. Fig. 6 is a vertical longitudinal section through a portion of the main frame and through the adjacent means for the mounting of the discharge roll.

As appears in Fig. 4, the machine consists of a feeding-in roll at the left hand, a part including four pairs of rolls for cleaning the tin plates, a part to the right of them includ-' ing two pa rs of rolls for polishing the plates, and the discharging end having a brush and discharging roll. In addition to the foregoing there is a bran receiver below the roll, a conveyer for lifting same and a discharge spout above the roll.

The frame of the machine consists essentially of two parts, the supporting frame having four legs 10 and side bars 11 near their lower ends. On said supporting frame there is an upper frame consisting of two side frames 12, cross end bars 15 and upper side bars 16.

The side frames 12- are provided with vertical bearing openings or slots 13 and 14 in which the boxes 17 and 18 of the rolls 19 and 20 are mounted. The rolls 19 are feed rolls made of metal or the like, while the rolls 20 are cleaning or polishing rolls and are covered with fiber 21. There is one of each type of rolls in eachvertically disposed pair of rolls and the positions of the rolls of the two types alternate, as indicated-in Fig. 4. The bearings 17 are mount.-

and the ed in a stationary position and are of two different sizes, as indicated in Fig. 5. The smaller square bearings 17 are for the lower feed rolls 1!) and rest in the lower ends of the slots 13. The bearing boxes 17 of the upper rolls 19 are mounted in the upper part of the slots 13 on shoulders 24, see Fig. 5. Said upper bearing boxes 17 are held down in position by the screws 25.

The bearing boxes 18 of the upper fiber covered rolls 20 are held supported in the grooves 13 by screws v26 that pass through the upper bars 16 of the frame and have heads on their lower ends rotatably mounted in extensions 27 on the upper side of the boxes 18. This permits a vertical adjustment of said bearing boxes. The boxes 18 for the lower rolls 20 are mounted in the slots 14 on the upper ends of screws 28, similar to the screws 26 but passing through a horizontal frame bar 29 and locked in place by the nut 30. The bars 16 are fastened to the main portion of the end frame by the screws 31. The two right-hand pairs of rolls, see Fig. 4, are mounted the same as the other rolls although they are for polishing purposes only.

Under the cleaning rolls, or first four pairs ofrolls, the bottom plate 35 is mounted, as shown in Figs. 4 and 5, on rods 36 that extend through the top of said bars 16 and are held and vertically adjusted by the nuts 37. This bottom plate at its ends abuts against the vertical end plate 38 and pro jects below the end plate 39, see Fig. 4, and the sides of the bottom 35 are spaced away from the frame on each side and also away from the side walls of the bran receiver 40, see Fig. 2. This is so arranged in order that the bran may fall over and down from the lateral and forward edges of said bottom plate 35 and escape into the receiver 40 and not bank up on the plate 35 so as to come in contact with the bearings of the rollers.

The bran is introduced upon the sheets of tin plate 40 near the first pair of rolls, see Fig. 4, through the s out 41. This spout is elongated laterally o the machine, see Fig. 2, and flares downwardly and is provided with partitions 44 formin spaces between them that flare downwar ly so that said partitions will distribute the bran laterally of the machine. The spout is rather narrow longitudinally of the machine so as to deposit the bran at one part thereof.

The bran falls on the first upper roll 20 and the tin plate as it is entering thefirst pair of rolls. Thus as the plate is fed through the machine its upper surface is sprinkled with bran and it is rubbed against the plate by the fiber roll which moves somewhat faster than. the tin plate. The bran accumulates on the bottom plate 35 and is maintained in the pile that reaches up to the tin plates and hence surrounds all of the lower rolls but not the upper rolls. The

lower fiber covered rolls revolving in the path of movement being determined by thestationary rolls 19.

The bran drops from the bottom plate 35 into the receiver 40 below, it being secured to the legsof the machine by brackets 45 and tapers downwardly and in the lower part thereof a screw conveyer 46 is located which moves the bran through the tube 47 to a vertical tube 48 through which the vertical conveyer 49 operates. From the upper end of the tube 48 the bran is discharged into the tube 50 which carries the bran to the spout 41. The conveyer shaft 51 is mounted in a box 52 at its lower end and carries a gear 53 meshing in the pinion 54 that is driven by a gear 55 and it in turn by gear 56 on the shaft 57 ofthe horizontal conveyer. The shaft 57 has on it a sprocket wheeldriven by the chain 58 running from the sprocket wheel on the shaft 59 that extends through the machine transversely. This shaft is driven by a drive wheel 60 from any suitable source of power. Power is transmitted to the rolls through the car 61 on the shaft 59 to the gear 62 on the s aft 63. From shaft 63 there is a train of gears on the left side of the machine for driving the relativel stationary rolls 19, and at the left hand si e of the machine another train of gears for driving the fiber covered rolls. The latter train of gears is shown in Figs. 1 and 2, there being a gear 64 upon the end of shaft 63 that meshes with the pinion 65 on the spindle of the larger gear 66, for driving the latter. The gear 66 drives a gear 67 and it in turn gears 68 and 69. These gears drive the cleaning rolls. For driving the polishing rolls the gear 66 meshes with an idle pinion 70 that engages a gear 71, shown by dotted lines in Fi 1 on a polishing roll 20. Connected wit a shaft of said roll a gear 72 is mounted that drives the gear 73 of the upper polishing roll. This latter "ear drives the sprocket wheel 74 and chain 75 and the sprocket wheel 76 on the spindle of the discharging roll 77, see Figs. 1 and 4. This driving mechanism is geared so as to give the cleaning and polishing rolls about one hundred revolutions per minute.

The feed rolls 19 are geared to be driven at a slower peripheral speed than the rolls 20. They are driven from a gear 80 on the shaft 63, see Fig. 2, which meshes with a gear 81 on the spindle of one of the rolls 19,

being at the lower left-hand corner of the rolls indicated in Fig. 4. Power is transmitted from the gear 81, shown also by dotted lines in Fig. 4, and the gears 82, 83 and 84. The last one of said gears drives an idler 85 that drives the gear 86 and it in turn gear 87 shown by dotted lines in Fig. 5.

On the spindle of the first roll 19, see Figs. 2 and 4, there is a sprocket wheel 90 from which a chain 91 runs to the sprocket wheel on the feeding-in roll 92, see Fig. 4. This roll is mounted in brackets 93 secured to the front end of the machine. Tin plates 40 come in over that roll and over the curved guide plate 94. The upper end of the artition 39 in the middle of the machine is a so curved to form a guide. A brush 95 is mounted in connection with the bars 16 of the side frames about the middle of the machine and extends down in position to sweep the upper surfaces of the tin plates as they leave the cleaning rolls, and brush the bran ofl them. There is also a brush 96 secured at the rear end of the machine in position to sweep the upper surface of the tin lates. As the tin plates issue from the polishing rolls at the rear end of the machine they pass under the brush 96 and over the discharge roll 77 This discharge roll is adjustably mounted in a pair of brackets 97 which are provided with horizontal slots 98 for the boxes 100 in which the roll is mounted and said boxes 100 are adjusted and held by set screws 99 so that the roll may be horizontally adjusted to move out closer to or farther from the brush 96. As seen in Fig. 6, the brackets 97 are also mounted so as to be vertically adjustable on the frame of the machine by bolts 101 extending through vertical slots 102 in the brackets. This enables the discharging roll 77 to be vertically adjusted to increase or diminish the pressure of the brush 96 on the tin plates and to accommodate said roll to plates of varying degrees of stiffness.

The conveyer tube 48 is braced in its vertical position by the brace 105 secured to the top of the frame-work of the machine and the tube 50 is supported by the supports 106 and 107 also secured to the frame of the machine.

For cleaning the bran from the rolls, the nuts 37 on the rods 36 supporting one end of the plate 35 may be loosened so that the end of the plate 35 will drop down, as indicated by dotted lines in Fig. 5. Then the bran upon the plate 35 and about the rolls can be readily removed. This is one important advantage of the construction, as it avoids the necessity of removing the rolls for cleaning the bran out of the machine.
