Q By A llorney Patented Sept. 22, 1931 JOHN PERRY, F WHEELING, WEST VIRGINIA TIN-PACK HANDLING- MECHANISM A mama filed August 9, mo. Serial No. 474,200.

This invention relates broadly to mechanisms for handling tin packs and the primary object of the present invention is to provide a mechanism for conveying the tin packs from the heating furnace to the roll thus dispensing with the manual labor heretofore utilized for such purposes.

A still further object of the invention is to rovide a conveyor mechanism for disposition between the furnace and the roller 'mill whereby the tin ack will be transferred directly from the conveyor in the furnace on to the conveyor mechanism to be conveyed by the latter to the mill, and-to be transferred directly from the said conveyor mechanism to the lower run of roller.

A still further object of the invention is to provide a conveyor mechanism for han-. dling tin packs which may be used especially so in such cases as where the roller mi is may be disposed to one side of the furnace.

A still further object. of the invention is to provide. a mechanism of the above mentioned character which also includes means for maintaining the edges of the sheet of the respective packs at the fronts and sides of the packs in true flush relationship whereby the edge of no one sheet of the pack will project beyond a corresponding edge of a second sheet of the pack.

Other objects and advantages of the invention will become apparent during a study of the following description, taken in connection with the accompanying drawings wherein: Y Y a Figure 1 is a top plan view of the improved mechanism,

Withreference more in detail to the drawings, it will be seenthat the reference char-. acter C designates the forward end ortion of a conveyor arranged within the eating furnace (not shown) and from which conveyor the tin packs are to be transferred on to my improved mechanism.

-For supporting the forward end of the furnace conveyor C there is provided a pair of longitudinally spaced standards 5 and 6, and between each of the pairs of standards a horizontal shaft 7 and 8 extend.

My improved conveyor or tin pack end mechanism comprises a pair of spaced parallel endless conveyor chains 9 that at one end of the conveyor are trained over suitable sprockets provided therefor for the shaft 8, and at the opposite-end'of the conveyor are trained over suitable sprockets 10 provided so therefor on a horizontal shaft 11 supported in a pair-of spaced standards 12 arranged remote from the furnace and adjacent the roller mill designted enerally by the reference .character M. be chains 9 are provided with tin pack engaging lugs 13', and the lugs 13 arearranged in airs for en gaging the rear end of the pac for moving the same with the conveyor chain and retaining the edges of the plates of the respectivepacksflush.

Adjacent one end of the conveyor chains 9 there are mounted a plurality of pairs of horizontally disposed allned shafts 14 and 15. The outerends of the shafts 14 and 15 are mounted in standards 16 and 17 respectively and the inner ends of the shafts 14 and 15 are mounted in standards 18 and 19 respectively. On the inner ends of shafts 14 and 15 are collars 20 and 21 and on the beveled gears 22 and 23. The shafts 14and 15 are oppositely threaded, and have threadedly enouter end of the shafts'are gaged therewith blocks'24 and 25 that have their lower end portions operable in cha'n-.

nel guide members 26 and27 whereby to re tain the members 24 and 25 against rotation but to permit of movement of the blocks 24 and 25 longitudinal movement relative to their" shafts 14 and 15, i v

Each of the guide blocks 24 and 25 are provided on opposite sides thereof with lateral shoulders 28 which cooperate with inwardly directed flanges 29 formed on the upper edge of the sides of the channel guides 26, 27 for retaining the guide blocks in their channel guides.

Arranged adjacent the forward endof the conveyor chains 9, or adjacent that end of the conveyor chains remote from the heating furnace is a pair of longitudinally alined oppositely threaded shafts 30 and 31 respectively provided on their outer ends with bevel gears 32, 33, while on the inner end of the shaft 31. is a' clutch member 34 provided with radial recesses or grooves for receiving radial tongues on a complemental clutch member 35 provided on the inner end of the shaft 30. The clutch member 35 is fixed to the shaft 30 while the clutch member 34' is slidably keyed to the shaft 314to any suitable means for movement into and out of engagement with the fixed clutch memchannel guide members 39 and 40.

are suitably supported in standards 41, 42

and their inner ends supported in' standards 43 and 44. I

It is to benoted, that the shafts 14, 15, 30 and 31 extend between the upper and lower runs of the chains 9 and at right an les to the chains.

he upper'ends of the guide blocks 24 c and 37 have suitably secured thereto and supported thereon an elongated channel bar, 45 while the upper end of the guide blocks 25 and guide block 38'have suitably secured thereto and support a like channel bar.46.-

The channel bars 45 and 46 have each arranged therein and extending for the full' length. thereof a .guide strip 47, 48, and the upper portions of the strips 47, 48 extend above the upper runs of the conveyor chains 9 and are adapted to contact the side edges of the packs carried by the chain for retaining the edges of the plates of the respective packs-in suitable vertical alinement same time to be moved relative to one another for accommodatlng packs of various widths and for positioning the packs on the chains laterally with respect to the chains as will be hereinafter more fully apparent.

Each of the standards 16 is provided with a laterally extending bearing bracket ,49, and the standard 41 is equipped with lateral bearing brackets 50. Supported in the bear-' ing brackets 49'and in the bracket 50 is a horizontally disposed-longitudinallyextending shaft 51 that is equipped with a pair of beveled gears 52 for mesh .with the gears 22,'together with a single bevel gear 53 for mesh with the bevel gear 32 on the shaft 30. That endof the shaft 5l adjacent the bracket50 is provided with a suitable hand wheel 54 for manually rotating the shaft.

Likewise each of the standards 17, isv

equipped with a laterally bracket 55 and the standard 42 with a'jlike bearing bracket 56. Rotatably mounted in the bearing bracket 55 and bracket 56 is a shaft 57 provided with a pair of-beveled gears 58 for mesh with the beveled gears 23, together with the beveled gear 59 for mesh with the beveled gear 33. The shaft 57 at that end thereof remote from the gear 59 is equipped with a suitable hand Wheel 60 for manually rotating the shaft.

From the. foregoing then it will be seen that when the clutch members 34 and 35 are engaged, and either shaft 51 or 57 manually rotated, the shafts 14 and 15, together with the shafts 30 and 31 will be rotated simultaneously for simultaneously moving the channel bars 45 and 46 inwardly-toward one another or outwardly away from one another for accommodating the various Widths of packs that may be conveyed on the chain extending bearing 9. When the clutch members 34 and 35 are out of engagement, it will therefore be seen that by rotating shaft 51 the channel bar 45 may be moved toward or away from the channel bar 46, the latter remaining stationary, while con'versely upon rotation of shaft 57 the channel bar 46 may be-moved inwardly or outwardly toward and away from the channel bar 45, the latter in this instance remaining stationary. In this manner, it will be seen that the guide members 47 and 48,may be so positioned relative to one another as not only to accommodate various width packs, but may also be positioned relative to one, another for so accommodating the packs even though the packs -may extend or project at one side thereof farther beyond 0r laterally of the adjacent chain 9 than the packs at theirv opposite sides project beyond the other of the chains 9. The referred to movement'of the channel bars 45 and 46 is of course transmitted to said channel bars from the shaft 75 mounted in standards 76.

spaced flipper shafts 14 and 30 and the shafts 15 and 31, through the medium of the guide blocks.

For the clutch member 34 there is provided an operating lever 61 that has a laterally directed forked end portion '62 for engaging an annular groove provided therefor in the clutch member 34. The outer 'free end of the lever 61 is slidably supported in any suitable bracket 63 provided therefor. The conveyor chains 9 are operated from a suitable electric motor E that includes a drive shaft 64 provided adjacent its outer end with a bevel gear 65 for mesh with the bevel gear 66 on one end of shaft 11.

Arranged transversely of the chains 9 at the forward ends of the chain, and adjacent the roller mill M is a pair of spaced chains 67 that are also equi ped with ack contacting ugs '68, the atter also eing arranged in pairs. The chains 67 are trained over suitable sprockets 69 and 70 mounted on transverse shafts 71 and 72. The shaft 71 is supported in a pairof suitable standards 73, and the shaft 72 is mounted in suitable standards74.

For use in conjunction with the conveyor chains 67 there is provided a suitable flip per mechanism which includes a flip fier e shaft 75 is provided with a plurality of members or arms 77 arranged one adjacent each of the chains 67 and the arms 77 are normally disposed in a horizon tal position whereby the tin packs on the chains 68 may normally pass thereover.

The shaft 75 is equipped with a crank arm 78. An eccentric 79 is provided on the shaft 71 and includes an arm 80 pivotally connected at its free end as at 81 to the free end of the crank arm 7 8. Apparently therefore when the shaft 71 is rotated, the shaft 75 will be also rotated and the flipper arm 77. raised froma horizontal position to a 1 vertical position suggested by dotted lines in Figure 6 whereby the pack may be flipped from the conveyor chains 67 on to the table T to be transferred from the tables T on to the roll of the mill M as Wlll be apparent from the study of Figure 1; 1

In order that the chains 9 may be operated simultaneously with the chains 67, or the chains 67 and chains 9 operated independ- 'ently with respect to one another, the shaft 71 is operatively connected with the shaft 64 of the motor E through the medium of a suitable clutch mechanism 82 that may be manually controlled through the medium of a pivotally mounted lever 83.

In' order that the flipper mechanism may be operated independently of, or simultaneously with the operation of the chains 67, the shaft 71 at said end may be engaged or disengaged from a shaft 84 through the medium of a clutch 85 controlled through the medium of a suitable handle 86 that is pivotally mounted for rotation on a horizontal' plane.

In this connection, it will be noted that the shaft 84 is suitably mounted in a hearing standard 87 and that one of the members of the clutch 85 is integral with the eccentric 79 that is loose on the shaft 71 while obviously the remaining of the clutch members 85 is suitably keyed to the end 84 of the shaft 71.

In order to maintain the forward edges of the plates of the respective packs flush with one another, as the packs are conveyed by the conveyor chains 9 there is provided a member 86 that extends upwardly between the chains 9 and at its lower end is suitably and pivotally mounted as at 87 to a base 88, the upper end of the member 86 is adapted to normally project upwardly beyond the upper run of the chains 9 to contact the forward edges of the plate of each tin pack successively and in this manner maintaining the forward edges of the-plates of the respective packs flush and even with one another. For normally retaining the member 86in a vertical position, there is provided a bolt 89 that has an eye connection 90 with an intermediate portion of the member 86. The bolt 89 extends horizontally through a suitable opening provided therefor in the upper end of a bracket member 91 rising from the base 38.

Convoluted about the bolt 89 is a coil spring 92, and one end of the coil spring bears against the sprocket 89 and the opposite end of the coil spring bears against a nut 93 threadedly engaged with the free end of the bolt. Obviously,'as the forward edgesof the pack,contact with the upper end of the member 86, the forward edges of the plate of the respective packs are alined,

and as the pack continues onwardly the member 86 is rotated about its pivot to assume the position shown in dotted lines in Figure 4 to again bring into vertical position'under action of spring 92 when the pack discontacted has moved farther along,

so that the member 86 at its u per end 15 again in position to contact the orward end 0 the next succeeding pack.

In actual practice, it is intended that the improved tin pack handling mechanism be arranged between the furnace as shown and the roller milland as is apparent from a medium of the members 47 and 48 the plates invention, it is to be understood that the same is susceptible to changes fully comprehended by the spirit of the invention, and the scope of the appended claims.
