SPEGIFICATION fQrming part of Letters PatentNo. 561 ,111, dated June 2, 1896.
Application filed September 5, 1892. Serial No. 445,074. (No model.)
To all whom it may concern.-
Be it known that I, JOHN G. HODGSON, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Im provement in Machines for Cleaning and P01- ishing Tin-Plate, of which the following is a specification.
My invention relates to machines for cleaning and polishing tin-plate or other metalcoated sheets after the same have been tinned or coated.
The objectof my invention is to provide a process and machine whereby this cleaning and polishing of the surface of the sheet may be done perfectly and with uniformity, so that the whole product may be alike and fit for any nseas, for example, the manufacture of cans for putting up condensed milkand whereby at the same time the work may be done automatically, rapidly, and cheaply and without the necessity of employing skilled labor.
I have discovered, and herein my invention primarily consists, that the tin or metal coated plates of iron or steel as they come from the tinning-bath maybe perfectly, uniformly, and rapidly cleaned and polished by holding the plates in contact with theupper surface of a rapidly moving or revolving mass of bran or other similar absorbent cleaning material, the mass of bran being stirred simultaneously or from time to time in order to present fresh material at its surface and to prevent the-bran at the surface of the mass from becoming fouled or charged with the grease removed from the tinned plates and which is absorbed by the bran.
In practicing my invention any suitable means or mechanism may be employed for containing the mass of bran or material and giving the mass a rapid movement or revolution, and the plates to be cleaned may be held in contact With the surface of the revolving mass of bran by any suitable mechanical devices or mechanism. v Likewise, too, the mass of bran may be stirred by any suitable me-, chanical means.
For practicing my invention, however, I prefer to use an automatic machine of the particular construction herein shown and de scribed which I have specially devised for revolving or moving the mass of bran, stirring and leveling or smoothing the upper surface of the mass of bran, and holding the plates in contact with the revolving mass of bran, and
in this my invention in part consists. This automatic machine comprises, first, a bin or vessel for containing the bran mounted on or secured to a central vertical shaft or axis adapted to be given a rapid revolving movement second, a series of stirrer-arms projecting downwardly into the mass of bran in the containing vessel and attached to stationary supports, whereby the mass of bran is stirred,
and, third, one or more sheet-holding devices,
preferably four, arranged above the vessel and adapted to hold the sheet in contact with the surface of the rapidly-revolving mass of bran, and each consisting, preferably, of a slowly-revolving drum, the shafts or axes of which extend out radially from the axis of the bran-containing vessel and are mounted parallel to the surface of the revolving mass of bran. These drums are furnished with a clamp or device for clamping one edge of of the revolving mass of bran, the drum also serving to press the sheet firmly against the surface of the movingmass of bran with the pressure necessary to clean and polish the same. By the rapid revolving movement of the bran-containing vessel the mass of bran, S5
owing to the centrifugal action, is compressed, so that it exerts a greater pressure against the sheet of tin held by the drum in contact therewith. The bottom of the bran-containing vessel is preferably dishshaped, as the surface 4 of the bran naturally assumes under the centrifu gal action a somewhat hollow or invertedcone form.
In the accompanying drawings, whlch form a part of this specification, I have shown one 5 form of apparatus embodying my invention and suitable for use in practicing it, and that which I believe to be the best form now known to me.
In the drawings similar letters of reference indicate like parts. 7 v
In said drawings, Figure 1 1s a central vertieal section; Fig. 2, a partial plan view. Fig. 3 is a detail section of one of the sheet-holding drums, showing the mechanism for automatically clamping and releasing the sheet from the drum; and Fig. 4 is an end view of one of the drums.
In the drawings, A represents the frame of the machine.
13 is the bran-containing vessel or bin, secured to or carried by a central upright revolving shaft C, by means of which a rapid revolving movement may be communicated to the mass of bran or other cleaning'or polishing material Hill said vessel. This brancontaining vessel is preferably about six to ten feet in diameter. The bottom I) of this vessel is preferably conical or dish shaped, as is clearly indicated in Fig. 1 of the drawin gs. The central portion of the vessel is preferably provided with a hollow dome I), which incloses the shaft 0 and keeps the bran from coming in contact with it or its bearings, and also serves somewhat to diminish the quantity of bran or material necessary to fill the vessel to the requisite depth. The shaft 0 has a suitable bearing 0 at its lower end and another bearing 0 on the frame of the machine.
I) l) are the revolving drums by which the sheets to be cleaned are held in contact with the upper surface B of the mass of bran ll. These are each furnished with suitable clamps or devices (Z for clamping the sheet thereon. The axes or shafts D of the drums preferably extend out radially from the upright shaft 0 of the bran vessel 13, and the shafts D are also, preferably, arranged in a somewhat inclined position conforming, approximately, to the dished or conical surface of the revolving mass of bran B in the vessel 13 which it naturally tends to assume under the centrifugal action. The shafts Dof the drums are journaled in suitable bearings l) on the frame of the machine. Each shaft is furnished with an internal gear I), which meshes with the gear 1) on the inclined shaft D carrying at its inner end a beveled gear D, which meshes with a beveled gear C on the shaft O, whereby a slow revolving movement is communicated to the drum from the shaft of the bran-containing vessel. The inclined shaft D is journaled in a suitable bearing 1) on the frame. The clamps (Z are automatically opened and closed to release and discharge the sheet by means of the stationary cams d on the box or hearing D of the drum-shaft I), which engage pins (1 carried by a slide 01 adapted to reciprocate radially in suitable guides d on the drum, and to which slides the clamps d are connected'bya cross-bar d. The clamps (l are connected to the cross-bar (Z adjustably by means of the set-screw d. F F are stirrer pins or fingers carried by stationary arms F, which extend out radially from the center of the vessel Secured to the arms F are fingers or racks H, which serve to catch or support the sheet of tin-plate G as it is discharged from the drum 1).
The mode of operation is as follows: As the drums D revolve over the surface of the revolving mass of bran B the clamps (Z are automatically opened and the operator then inserts a sheet under the clamps and holds it there as the drum revolves until the clamps dare automatically closed. As the drum eontinues to revolve the thin sheet of tin plate is carried around by the drum and each portion of its surface held by the drum in contact with the revolving mass of bran a regular and uniform length of time, so that the whole surface of the sheet is acted upon alike and properly cleansed and polished. As the drum continues to revolve the sheet is carried around thereby until the clamp (Z again automatically opens, when the sheet slides down the periphery of the drum and falls into the rack II. The operator then turns the sheet with its other face to the drum, and then its other surface is cleansed and polished in the same manner. The stirrers F are preferably made of different lengths conforming to the conical or dish shaped surface which the mass of bran tends to assume under centrifugal action, so that the fingers themselves will thus tend to maintain the surface of the bran smooth or plane. As the drums D are several in number, they also tend to level or smooth the surface of the revolving mass of bran, and the centrifugal action likewise tends in a measure to this result. The drums D are preferably arranged to revolve in the opposite direction to the vessel 13. As the sheets bend around the drum the drum presses the sheets against the surface of the bran or cleaning material, and the spring or elastic nature of the sheets, together with the gravity of their free ends, also aids in pressing or holding the surface of the sheet in contact with the revolving mass of bran. or cleaning material in the vessel 13.
ll is a guard, preferably in the form of a leather or felt covered roll, extending parallel to the drum 1) and journaled in suitable brackets II, attached to the frame. The object of this guard is to prevent the thin flexible sheet dropping away from the drum as the clamp or gripper (l is carried with the axis of the drum.
The vessel 13 is supported upon the shaft C by an adjustable collar 0 fixed t0 the shaft G by a set-screw C. liy adjusting this collar up and down the height of the vessel ll in respect to the drums D may be regulated or varied to give more or less pressure of the sheet on the bran or other cleaning material.
By the use of the word bran in the specification and claims I desire to claim any suitable cleaning material in a loose, granular, or powdered form.
I claim- 1. The automatic tin-plate-cleaning ma chine herein described, consisting in a revolving bran-containing vessel 1- mounted on an upright shaft C, a series of revolving drums mounted on shafts extending radially from the shaft of said vessel and provided with clamps for securing the sheets to the drums, and stirrer arms or fingers attached to the stationary frame and projecting into said vessel B, substantially as specified.
