While the die blocks are shown as equipped with the usual simple form of co-actingymale and female elements in Figures 2 and 4 of the drawings, it is to be understood that the present marker is particularly adaptable to use in heavy duty marking wherein the marking dies are equipped to mark the end closures over the whole ' or a major portion of the surfaces thereof, in cluding curved line embossing which demands 10 precise interengagement of the male and female ' embossing elements.

After each adjustment of the eccentric sleeve ‘I6 the screw adjustments v8.0 are-utilized to adjust the gears ‘H! and 13 relative to the shaft 15,. thereby to restore ‘Perfect regis tering relation of the male and female die ele ments. } , The marking equipment .as herein described is» cap-able of being operated at great speed in marking and has a capacity for making heavy impressions with rotary diev elements which may cover the whole can'end with embossing; instead of the usual one or two lines of characters. .It will also be obvious that the marking equipment and the end closure feeding devices can be; :ad justed order toupwardly adapt'the or closing downwardly machine as. aforwhole closing The intermeshing gears 61, 10 and 13 are pref erably protected ‘by a removable cover 92 at 20 containers of different heights.

Thus by loosening the clamping or securing screws 33 and 63 and by rotating the hand wheel 31, upward or downward movement can be impartedv to the screw column 28, the markerrbody 60, '64, the hanger bracket 56, the 30 bracket extension '54, the bracket plate 32, the plate or table 35, and the end closure stack or feed 38 and the depending housing 39 supported by said plate. It will be obvious that spline shafts 22 and 26' will move vertically with the parts just mentioned without disrupting the. power transmitting connections to the marking parts or to the end closure feeding devices.
