These parts are not further detailedas the details thereof form no partgof my present The :bed. 2' is formed of a pair of plates 5a 1 1 and 15 having telescoping flangeslG and 1' 16 at their edges. The plates are held in spacedrelation by the shouldered spacing spools 17; @Thespools also constitute,sup-, ports for the posts 18 p a t a '1 60 ;These posts are provided with heads'19 at their upper ends and are shouldered at 20 to 511121111311, nested Within the cam member23 The posts arealso provided with clamping nut 24:; below the bed sothat the cam members areclampedupon thebed. v These-cam members in the-emhodimentfillustratecl' are cupped stampings, theirflanges o The bed is provided with holes 25 Which are engaged by lugs 26 on the outercam members, theseholes being positioned in the upper plateof the bed .to properly position a the cams. To'position the inner and outer cam-s relative to each other, the outercamsare provided with recesses. 27 and the inner cam. member with lugs 28, these lugs, and, I

pairs'of camsrelative to each other. H Byflthis arrangement the outer cams may all be formed by one die,,that is, they are all alike, and the inner cams are also all alike, v 3 I so it is merely a matter of positioning them In the: embodiment illustrated I provide a relative to each other on thebed to properly control, the coacting mechanism a'nd they are clamped in place bythe posts. The clamp members 21 also serve as end thrust members for the rotary heads designated generally by the numeral 29. These heads-consist of hubs 30, top pl'ates 31 and bottom plates 32 held in properly spaced relation by the spacing sleeves 38arranged bet-Weenthe plateson thehub. The gears 34 are also mounted on the hubs and .areheld in' properly spaced relation to the bottom plate 32'by the rings 35 and rings 36 arranged below the gears- The gears are arranged in meshing relation.

t The plates and gears are preferably stampv ings andapressed fit on thehub' so that they are held in proper assembled relation thereon without other attaching means; The lower end ofthe hub and the lower ring 36 con-i -stitute'an end thrust bearing coacting with; the iblampin'g me mbe'rs 21,*the heads 19-fof V the posts retaining the'rota'ry heads thereon.v

The latches are i 7 m0unted*for verticalTmovement;'in" 'al1ined keepers39 which are. engaged by the latches hel'es 42 in the head plates and also "projectthrough the holes 43 in thefgears; The-holes in the gears are also preferably of such size 3 as to serve as bearing supports for the latches.

The-latches" are "provided with laterally v projecting "arms tt having 45 thereon to receive the springs46.
