To all whom t may concern."

Be it known that I, CHARLES M. REYNARD,

g a citizen of the United States, and resident of McKeesport, in the county of Allegheny and State of Pennsylvania, have invented a new and useful improvement in Apparatus for Cleaning Tin Plates; and 1 do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to apparatus for cleaning tin-plates.

ln the manufacture of tin-plates, the sheets are passed from the tinning-pot where they receive their coating of tin to cleaning apparatus to remove the oil and the dirt mixed with the same, which may adhere to the plate as it comes up through the palm oil which covers the tin in the tinning pots. 1n order to remove this' oil or grease the plates are passed through rolls which revolve in a suitable receptacle containing sawf dust, bran or other mlxture which wlll remove this oil or grease as the plates pass through it. i

rlPhe object of the present invention is to provide apparatus of this character in which the saw-dust, bran or other material, which is carried out of the receptacle by the movement of the plates through the body of material, is discharged into a suitable receptacle below, so that it may be conveyed upwardly and discharged again into the receptacle, by being evenly distributed across the rolls contained therein, and the invention comprises the novel features hereinafter set forth and claimed.

ln the drawings, Figure l is an end view' of my improved apparatus, and Fig. 2 is a longitudinal sectional View.

The numeral 2 designates a suitable stand or frame which supports the -box or receptacle 3 containing the bran, saw-dust or other mixture, 4f, for cleaning the sheets. rllhis frame also forms the support for the driving mechanism for driving the rolls and the conveyers. rl[`his driving mechanism consists of the pulley 5 whichis'mounted on the shaft 6 journaled in bearings in the bracket 7 and the stand or frame 2. Rotary movement is imparted to the pulley 5 by means of a belt leading from a suitable motor or engine. The shaft 6 has the pinion 8 which meshes with the gear-wheel 9 on the stub-shaft 10. A pinion 11 on the stub-shaft 10 communicates rotary movement to a train lof gears 12- rllhe front wall 15 of the box 3 has the slot 16 y for the entrance of the plates to be passed through the rolls. The bottom plate 17 of the box 3 is removable, being arranged to slide in guides and is provided with the handle 18 by means of which said bottom may be inserted or withdrawn.

The frame 2 contains the receptacle 19 with the inclined walls 20, and at the bottom of said receptacle, extending transversely of the frame 2 is the spiral conveyer 21 carried by the shaft 22. This shaft 22 is journaled in suitable bearings in the frame 2 and at one end of said shaft is the sprocket wheel 23. A chain 24 engages said sprocket wheel, said chain leading from the sprocket wheel 25 on the shaft 6. ln ,this way rotary movement is imparted to the spiral conveyer 21. The spiral conveyor 21 extends out into the inclined passage 26 which communicates with the upwardly extending passages 27. A bevel pinion 28 on the shaft 22 meshes with a bevel pinion 29 on the shaft 30 which carries the spiral conveyer 31 working in the passage 27. rfhe upper end of the passage 27 communicates with the curved passageway 32 which is formed of an elbow section 33 connected to the passage 27 by the collar 34 which is adapted to turn on the upper end of the passageway 27.

The curved passageway 32 discharges into the hopper member 35 extending transversely of the frame 2, said hopper member being supported on the swinging bracket 36, which is hinged to the box 3 atl 37. The bottom of the hopper 35 is provided with the longitudinally extending slot or opening 38. A slidable cover 39 controls the size of the opening 38, said cover being held in any desired position by means of the set-screws 40. Contained within the hopper 35 is the spiral conveyer 41 mounted on the shaft 42. lf his shaft 42 is providedl with the sprocket wheel 43, and achain 44 connects said sprocket wheel up with the sprocket wheel 45 on the shaft 46, which is driven by the train of gearing 12.

The plates to be cleaned, as they come from the tinning-pots, 'are inserted into the opening 16 at the front end of the box 3, and are taken up by the first pair of rolls, and are fed forward through the succeeding rolls passing through the bran', saw-dust or other cleaning material 4, and as the plates pass through and over the end wall 14, a

certain amount of cleaning material will be carried over with .said plate, and this will fall down into the'receptacle 19 and into position to be operated on by the spiral conveyer 21. This conveyer 21 conveys this cleaning material into the inclined passage 26, where it is forced alonginto the passage 27 to be taken up by the spiral conveyer 31 and discharged at the upper end thereof into the passage 32, whence it is discharged into the hopper 35. The spiral conveyer 31 in said hopper moves it along said hopper until it reaches the opening 38, whence it is discharged into the box 3 at a point adjacent to the first pair of rolls 13. By having the inclined passage 26, there is no clogging up of the material but it is forced up the inclined passage 26 to be engaged by the spiral conveyer 31 in the passage 27. In this manner I provide for the recovery of the cleaning material which is carried from the cleaning box by the plates in their passage through the rolls, and this cleaning material is conveyed rapidly back to the point Where it is discharged into the cleaning box, so that the cleaning box is constantly being replenished and' interruption in the work due to the replenishing of the cleaning box is avoided, while at `the same time cleaning material is so evenly distributed in the box as to prevent the collection of cleaning material in piles at any one po1nt.-

When the cleaning material has become saturated with oil and grease, and it is nec# essary to remove such cleaning material and introduce a clean supply into the box, the sliding bottom 17 is withdrawn, which allows the material to drop into the recepta-4 cle 19 and it is conveyed off by the `spiral conveyers in the manner above described, but in order not to return it again to the hopper 35 the elbow 33 is turned around in position to discharge this material in another' direction, and when all the material has been removed in this way, the slide 17 is inserted. The bracket 36 is then swung back together with the hopper 35 which gives easy access to the boxfor the introduction of a new lot of cleaning material.

What I claim is:

1. In apparatus for cleaning tin plates, the combination with asuitable frame, of a receptacle for containing the cleaning material, power driven rolls mounted in said receptacle, a second receptacle below said first named receptacle, a hopper member above said first named receptacle having an elongated opening extending across said first named receptacle, a conveyer in said hopper member, and means for conveying the material from said second named receptacle to said hopper member.
