TINNING-MACHINFE.

SPECIFICATION forming part of Letters Patent No. 520,428, dated May 29, 1894.

Application filed January 9,1894. Serial No. 496,319. (No model.)

To all whom it may concern.-

Be it known that I, J OSEF HIRSOHMANN, a subject of the Emperor of Austria-Hungary, residing at Liniield, in the county of Montgomery and State of Pennsylvania, have invented new and useful Improvements in Tinning-Machines, of which the following is a specification.

My invention relates to such machines, in which thin charcoal iron plates are tinned after they have been scoured, cleaned and pickled in the usual or any preferred manner. With the machines heretofore constructed, many difficulties were experienced in the operation thereof, owing to the imperfect guiding and feeding mechanism for the plates as they were carried through the tin-bath but with my improved machine such difficulties are removed.

In my improved machine hereinafter more fully described, I employ continuous guides for the plates, transferring or feed rolls between them to take hold of each plate at its center, whereby a uniform and straight motion of the plate is obtained and any edgewise feeding of the plates is obviated, while the continuous guides prevent any winding or curling of the plates around the said feed rolls.

In my improved machine and by the use ofchain carriers and automatic clutches,-

which latter carry the plates through a fluxbath, a tin-bath and an oil-bath and then through bran contained in a box and automatically deliver the finished tin-plate, without having received any marks whatever, on a table, the number of attendants is reduced to a minimum.

My invention consists of devices assembled and operated to constitute a tinning plant, and it further consists of certain improvementsin the feeding, guiding and cleaning devices as will be hereinafter more fully described and pointed out in the claims.

The invention will be more fully understood taken in connection with the accompanying drawings forming part hereof, and in which Figure 1, is a view illustrating my improved tinning plant, and showing at the left, chain carriers for the feeding of the iron or other plates into the melting pot supported over a furnace, and at the right of the sheet the bran box, depositing table, 850., and also the operating mechanism for the different devices. Fig. 2, is a sectional view of the furnace supporting the melting pot containing the improved plate guides and feeders, and also showing the oil reservoir with improved delivery mechanism, a rotatably mounted funnel for guiding the plates between the finishing rolls, and the operating devices for the difierent parts. Fig. 3, is a plan view of the melting pot with its plate operating mechanism, showing also the plate feeding table and chain carrier and the oil reservoir with the finishing rolls. Fig. 4, is a vertical section on the line 44 of Fig. 2. Fig. 5, isa similar section on the line 55 of Fig. 2. Fig. 6, is an elevation of a plate clutch attached to the links of a chain carrier, the chains of which are held in stationary guides provided with opening wedges or devices for the said clutches. Fig. 7, is a side elevation of the clutch and opening devices shown in Fig. 6. Fig. 8, is aplan view of the chain guide showing the chain with clutching mechanism in position. Fig. 9, is a similar View to Fig. 6,'

with the exception that here are shown the stationary opening devices for the clutches, which cause the disengagement of the plate from the chain carrier. Fig. 10, is a section on the line 10-10 of Fig. 9. Fig. 11, shows in perspective a portion of a chain carrier adapted to carry the tinned sheets from the oil reservoir through the bran box and showing attached thereto spring clutches as illustrated in Figs. 6, 7 and 8. Fig. 12, is a section of a melting pot with modified plate carrying or forwarding devices, theplates being carried by books on an endless chain through the continuous guides immersed in the tin bath. Fig. 13, is a'vertical sectionon the line 1313 of Fig. 12.

Referring now to the drawings for a further description of my invention,'Ais the melting pot of cast iron or other material, supported on the furnace A, and this pot A carries one end of the plate feed B, the flux box 0 and the oil reservoir D.

The plate feed B comprises a slanting table b provided with a central slot 1) and an endless chain 1) passed over two sprocket wheels b and b the latter being driven from the main shaft A by a chain 1 and wheel b on the shaft of the plate feed supported by the melting pot A. The chain 1) is provided with hooks or projections o which move the iron plates along the table I); the latter is curved at b so as to extend into the flux box 0 and directly above the funnel e of a guide to be presently described. The table I) is further provided at the curved end b with a hinged cover b which may be fastened at its free end by any suitable catches to the table 17, to guide the plates around the curved end b of the table I) and into the funnel e. The object of hinging this cover 6 at b is to allow cleaning of the chute formed by the table b and cover b and to prevent any sticking together of the two parts by the solidification of the flux contained in the box 0, should the machine be out of operation during night or other times. 12 is a spring,

which may be employed to regulate the feed of the plates into the funnel and guides before mentioned.

In the melting pot A is provided on each side thereof one continuous curved guide E extending about the Whole length of the pot A, and at the left hand terminal the guides on both sides are opened to form a funnel e, which is directly below the chute aforesaid. At certain points closer in distance than the length of the plates to be tinned are sets of feed rolls E, in the present instance four in number, which are mounted centrally between the guides E and upon shafts e and e the lower shafts e are journaled in bearings provided in the guides E, which are held in place in the pot A by the depending plates 6 and cross plate e? fastened to each other and the pot A by bolts. The upper shafts e however are journaled in slide beari n gs e the ways e of which are formed with the guides'E, and the rolls E of the shafts 6 can be adjusted with reference to the lower rolls E to accommodate different thicknesses of plates to be tinned or to produce more or less pressure on the said plates; the roll adjusting devices are as follows, each slide bearing 6 is provided with a projection c with which a lever e hinged to one side of the way a engages; two such levers e of ad jacentbearings are coupled by slotted connections 6 to a rod e projecting beyond a bearing a of the roll and guide frame supporting plate a, and between this bearing 6 and an adjustable collar 6 is placed a pressure spring 6 which tends to press the top rolls onto the lower rolls, and this pressure may be-increased or decreased by turning the screw hand wheels e to adjust the springs e.

The rolls of each set of feed rolls E are geared together by wheels 6 and the shafts e of the lower rolls are driven by suitable sprocket wheels and the

chains

3, 4, 5 and 6 from the counter shaft A", which receives motion from the main shaft A by the sprocket wheels and the chain 2. All the guides and rolls with their adjusting devices and operating mechanism, together with the shaft A are held on the cross plate 6, so that by removing the latter,'the whole apparatus can be lifted out of the melting pot A for repair, cleaning or for any other purpose.

At the left hand side of Fig. 2, is provided the usual flux-box O, which is detachably connected to the melting pot A, and at the opposite end of the melting pot and extending into the same, isdetachably fastened the oil reservoir D. The Walls of the latter carry a removable frame (1, in which the sets of finishing rolls d'and d are held, one roll of each set is journaled directly in the frame d,while theother is journaled in slide bearings d properly guided in ways of the frame; each slide bearing is provided with a bifurcated stem d, which engages with a lever d. The latter are hinged with their lower ends at d on opposite sides of the frame 01 and are provided at their upper or free ends with clevises (Z and each two opposite levers d on one end of the two sets of rollers d and 01 have one turnbuckle d for the clevises d to draw together or separate at will the free ends of the levers (Z and thereby the rolls d and 11 to adjust the pressure of the rolls or to accommodate different thicknesses of plates. The sets of finishing rolls d and d are driven from the main shaft A by sprocket wheels and the chains 7 and 8.

Directly below thefinishing rolls d is provided a rotatable funnelfhaving trunnions f which are journaled in extensions of the frame cl. This funnelfguides the plates as they issue from the guidesEand rolls E into the frame (1 respectively into the oil reservoir and between the finishing rolls d and d and the object of making the funnel rotatable is, to gain access to the dividing line of the molten tin and the oil, as there are always collecting impurities of either substance and the attendant in charge should be able to remove the same, when it becomes necessary and without having to remove most of the machinery contained in the oil box. On one of the trunnionsf' is provided an arm f to which a shifterf is hinged, and at the upper end of the shifter is provided a cotter pin f engaging a bracket f to which the shifterf may be safely locked by the pin, when the funnel is in position to act as a guide.

In same cases of accident or repair, the finishing rolls and their connecting devices must be removed and this can easily be done by unscrewing the frame cl from the brackets d as all such devices are mounted on the frame (1 which then may be lifted out of the oil, which may remain in the reservoir undisturbed, in contradistinction to the old make of such machines where the oil had to be pumped out of the reservoir and the latter had to be removed and replaced, &c.

To carry the tinned plates from the finishing rolls d and d to and through the bran box G and deposit them automatically onto the table H Fig. 1, I employ achain carrier I,

which passes around the studded chain wheels d Figs. 2 and 5 to 8, then upward and around the set of eccentric wheels '5, then over the wheels 1' in the bran box G, the wheels 71 through the brushes k and it, around the idlers 2' the eccentric wheels 71 and back to the wheelsd The wheels pertaining to a set for instance the eccentric wheels t" or t are each keyed to a shaft, so that an equal movement of the carrier chains 2' is insured; the chain carrier I is-operated from the main shaft A by the chain 9 leading to the counter shaft 2, which is geared to the shaft of the eccentric wheels i by the wheels i to reverse the motion of the said eccentric wheels i and the upper eccentric Wheels 2" are driven from the counter shaft '5 by the chain 10. This chain carrier I consists of the chains iprovided with automatic clutches n, fastened or formed on links of the chains 1' at certain distances, the length of the plates to be tinned plus a clearing space of about one or two inches; the clutch ncomprises a jaw n fixed to a link of the chain 1' and a sliding jaw 72?, the former is provided with a slot 72 and a bore 01 in which latter the stock n of the sliding jaw n moves. This stock n is provided with a collar 02 and a spring n which presses against the fixed jaw n to normally hold the sliding jaw n against the jaw n and clamp a sheet between them; on the other end of the stock of, is attached a roller n ,which when brought into contact with a wedge n and moved along the same, separates the two jaws to either allow a sheet of tin or other plate to enter the jaws or to be released fromits grip. To guide the plates as they leave the finishing rolls 01' into these clutches n, funnel shaped projections 01 are provided on the fixed jaws it. When ever the opening of the jaws n and n has to be accomplished either for gripping or releasing a plate 00, the chains 2 are led through guides Z fastened to brackets L attached to the oil reservoir D and brackets L on the table H respectively, to insurethe proper engagement of the rollers 92 on the stock if of the sliding jaws n with the wedge n of the said brackets L or L.

The eccentric wheels t" and 2' are provided to cause the chain carrier I to move at intervals slower orfaster, 2'. e. the plates ware fed quite a distance into the clutches, before the latter are allowed to grip the said plate, and the clutches move at such feeding quite slow being almost motionless; but as soon as the chain carrier passes onto and over the major axis of the eccentric wheels t" it makes up for the speed lost, while gripping the plate, as willbe readily understood.

In Figs. 12 and 13, I have shown a modified form of forwarding mechanism in the melting pot for the sheets to be tinned. In this instance the guides E and mechanism in the oil reservoir D remain the same, the only difference being, that instead of feed rolls E being employed, use is made of an endless chain K provided with hooks k to engage the plates as they leave the feed table I), which in this instance is provided with two feed chains b the chain K is mounted around a driving wheel driven from the chain feed shaft by suitable gearing k and passes around idlers or rollers k The chain K drags along the under edges of the guides E insuring thereby the engagement of any plate, which may have been fed between the guidesE from the table I) and bringing the said plate through the tin bath, to the delivery rolls E and the finishing rolls d and d which are adjustably mounted as before described.

If preferred or found necessary, a guide or trough T may be attached to the guides E, to carry the chain K and make sure of the projecting of the hooks it beyond the guides E.

The operation of my improved machine or rather tinning plant is as follows: Motion is imparted to the main shaft A which operates allthe parts hereinbefore described, and the charcoal iron or other plates are placed on the table I) from which they are conveyed into the flux box 0 and guides E by the chain feed B, and before the hook b releases the plate, the first set of feed rolls E have taken hold of the plate and fed it to the next set of rolls Eand so on until it passes the finishing rolls. Itis evident that the speed of these rolls should be the same as the feed of the chain feed 13, or in other words, the plates must be forwarded as fast as they are fed into the guides E by the chain feed 13. From the finishing rolls d,the plates are taken as before described by the clutches n of the chain carrier I, and are carried through the bran box G where most of the oil is wiped off, and are then brought above the table II where the clutches n are automatically opened by the brackets L, to allow the plates or to be deposited on the table H. The chains 2' and clutches n of the chain carrier I then pass through the brushes k and k where the former are cleaned, so as not to bring any bran or otherimpurities into the oil reservoir D.
