While I propose under ordinary circumstances to use a rigid stop, it is to be distinctly understood that it may be given a yielding action in any suitable manner-for example, by providing its upper surface with a leather pad or cushion, as indicated by dotted lines c, Fig. 2.

In practice it is found that a stop such as herein described answers an excellent purpose in the protection of the matrices and that it does not in the least interfere with the introduction of the usual Wedge spacers or justiiiers, which hang down through the line,

What I claim as my invention is- I. In the assembling mechanism of a linotype-machine, a centrally-located stop in the path of the incoming matrices to encounter their lower ends.

3. In a linotype-rnachine, the assembler' 'of an assembler to receive the matrices, a

yielding stop to arrest the advance of each matrix before reaching its iinal level in the assembler.

In testimony whereof I hereunto set my hand, this 21st day of December, 1900, in the presence of two attesting witnesses.
