Title: Improvements in or relating to machinery for use more particularly in the manufacture of tinplates and the like
IPC: C23G5/00
Filed: 1928-11-01
Abstract: 322,300. Thomas & Co., Ltd., R., and Davies, D. H. Nov. 1, 1928. Cleaning. - In apparatus for effecting the cooling, and so facilitating the scaling, of metal bars or billets, particularly for use in the manufacture of tin plates, in which the bars are placed on a horizontal table which is then tilted so that the bars are immersed in the cooling medium, the table is connected with mechanism which, when the bars are treated in pairs, automatically separates the two bars when the table is tilted, or, when one bar only is being treated, automatically separates the under surface of the bar from the table surface, so as to ensure thorough cooling of the bars or bar. A table 8 of grid formation is pivoted on a spindle 9 carried by a framework 10 fixed to one end of a cooling bath 11. An adjustable counterweight 13 on levers 12 attached to rearward projections 8<a> of the table normally holds the table in a horizontal position. A downward projection 14 from the table is connected by a link 15 with the lever 16 which is pivoted on a spindle 17 carried by the framework 10, and the upper end of the lever 16 is pivotally connected wjth a weighted pawl 18 which effects the separation of the bars. The distance of the bottom front edge of the pawl above the table is adjusted by the screw 19 which abuts on a face of the link 16 so that the distance is just greater than the thickness of one of the bars. The, weight of the bars when placed in position causes the table to tilt, and the linkage gives a forward motion to the pawl which causes the uppermost bar to rise up an inclined projection 8<b>, the position of which on the table may be adjustable. In a modification, Fig. 4, the tilting of the table is effected by a hand-operated lever 21 and the pawl is replaced by a rod sliding in an arched guide. A turntable comprising rollers 23 mounted in a frame 24 carried at the upper end of a ram 25 slidably and rotatably mounted in a sleeve 26 may be used to turn the bars so that the end that requires less cooling is disposed towards the pivot of the table 8. A pedal 27 effects the raising and lowering of the ram, and when lifted the turntable rotates under gravity, rollers 28 cooperating with a cam track 29.
