To all 'Ll/'700712, ift iii/Ly con/cern:

Be it known that I, HANS GoLDsoHMID'r, chemist, a subject of the King of Prussia, German Emperor, and a resident of Essen-on-the- Ruhr, in the German Empire, have invented a new and useful Method of Dressing Tinned Sheet-Iron Boxes, of which the following is an exact specification.

My invention relates to a method of and apparatus for dressing tinned sheet-iron boxes by machines for the purpose of separating the surfaces of the boxes in equal manner on all sides. The following' conditions must, therefore, be fulfilled for practicing the matter: The boxes must be compressed, so as to occupy a small room only, and, furthermore, the dressing of the boxes must be so effected that the dissolving agent can circulate at both sides of the plates from which the tin is to be taken off. These conditions are fulfilled in my new method of dressing tinned sheet-iron boxes, consisting therein that the boxes are pressed together between mechanically approaching and retiring surfaces and are simultaneously or afterward perforated by suitable means.

ln order to make my invention more clear, reference is made to the accompanying` drawings, in which Figure 1 shows a front View of a convenient apparatus for practicing my method. Fig. 2 is a cross-section on line A B of Fig. l. Fig'. 3 shows another constructional form in side view. Fig. 4 is a horizontal section of the apparatus according to Fig. 3. Fig. 5 is a further constructional form in side view. Fig. 6 is a corresponding plan view.

ln the. drawings, c is the standard of the apparatus.

f f2 are tooth-wheels actuated by any con- Venient means driving' the pulley g, fastened to the axle of tooth-wheel f.

/t /t are two eccentrics fastened to the axle of wheelfz and moving' the rods e' up and down. The rods e' are fastened at their lower ends to a plate 7e', guided in the frame by the guide-pieces Z Plate carries at its lower end a plate ato which points c c are detachably secured. is a second plate strongly fixed on the standard e parallel to and opposite plate a and being' provided with holes c/ c',into which the points c c enter in passing down. Z is a second plate between a, and 7), with holes in which the points c c may remain in their utmost position.

`a is a belt for feeding the box to be dressed, consisting' of single strips and arranged in corresponding' grooves of the rollers 'a a, mounted in frames n fr. The belt fa must be formed from single strips in order to be not destroyed by the points c c.

The working of the apparatus is as follows: The boxes to be dressed are laid down upon band n and by conveniently actuating' the rollers m are brought upon plate N ow the plate a is nioved down, thereby compressing and perforating the boxes by means of the points c c. Now the plate or carrier then vretires in moving upward, the plate Z frees the now compressed and perforated box from the upward moving point c, the band further advances and carries the dressed box out of the apparatus, the box being' now ready for taking off the tin and regaining the iron. For surely freeing the boxes from the upward moving points c the plate Z may also be moved down and approached to the plate L.

Fig. 3 shows an arrangement in which two rollers o 02 are provided with points upon their circumference andare arranged parallel to and near each other, so that in turning' both rollers the points enter between each other. y is a pulley actuated by any convenient means and driving the gears b2 7235", thereby rotating the rollers o 02. The boxes to be dressed are placed from above in the direction of the arrow, Fig. 3, between both rollers, are seized by the points and drawn in between both rollers and leave the apparatus after being compressed and perforated beneath the rollers.

Figs. 5 and 6 indicate an apparatus consisting' of a plate r, a roller s, fitted out upon its circumference with points. The roller may be rotated in any convenient manner, and in rotating' its points enter corresponding' holes in the plate fr. The boxes to be dressed are placed between r and roller s in the direction of the arrow, Fig. 5, are drawn down, and leave the apparatus after being' compressed and perforated.

The apparatus described only illustrates IIO some of the best devices for practicing my method and may be varied in different ways. For instance, instead of reciprocating the carrier It' by means of eccentrics means may be devised which only raise the carrier 1, and thereby the plate e, and then release these latter, so that the carrier 1, with its plate a, Jfalls down and acts in the manner of a stamping-hammer. The free falling is, however, limited so that the surfaces of the boxes do not touch each other, so as to allow to circulate afterward the dissolving' agent on all sides of the plates.

I am aware that further changes in the form and proportion of parts and details of construction ot' the devices herein shown and described can be made without departing from the spirt or sacrificing the advantages there- HANS GOLDSCHMXDT.
