I 4 w According to my invention in its application to '7 a Linotype machine,'I insert a'cut-away liner or filling strip 01' suitable width, under the mould at each end of one of the moulds formed in or on the rotatable mould disc. One of these cut-away linersor filling strips projects into the mould a distance equal'to the width otthe furnititre tofbe produced, serving to form a step'at oneerldottheiurniture, Y

W to allow of themolten metal, delivered from ,the melting pot entering that portion of the mouldimmediately above the projecting portion 1 oflaid liner or filling strip, I partly cut away the 1 ribs formed on the corresponding end of the gmould-can.

I also provide an ejector blade of appropriate length for pushing the cast iurhiture from its mould into a chute below by means'oi' which the furniture is deliveredto the tray provided at the treat of the machine for reception of slugs cast Should itbe desired to form a, step at both ends I or the i'urniture I may employ two extended liners or filling strips, one being inserted at end otthe mould, in whichcase the ribs at mum having a plurality (orm radially about its centre which be moved into 'a. position between.

Where the furniture is=required for the setting up of type matter or cutting andcreasing means which will be-subjected to much use, it is advisorder to allow ofits' tendency in common with, other printing iurniture, to creep towards the level of the type faces oredgesiof the cutting and creasing means as the case might be, and interable to reduce the height, of the furniture in j fere with the eflicientout-put oi the machine in which the chase is mounted.

To provide for this the height of the furniture may be reduced by cutting in the usual manner, but preferably Iemploy a filling strip having its face formed complementary to the front portion of the mouldingcavity, and capable of beingrheld in one of the usual slide blocks, say. a border 7 block,, employed in the machine, so that thebreadth of said cavity will be reduced accordingly.
