Abstract: 21,087. Cleveland, A. J., [Brackelsberg, E. W.]. Sept. 27. Stereotype-matrix and like machines; linotype and like machines.-A machine for forming line, word, or letter type-matrices in a prepared cardboard, strawboard, &c. strip is shown in sectional elevation in Fig. 1. The impressions are made by means of a hammer E and dies disposed in notches in two carrier strips sliding in a divided groove in the bed A. The carrier strips are hinged to handles C<3>, C<9>, Fig. 3, provided with pegs C<8> for adjustment in orifices D', D<1>, Fig. 1, in an inclined indicator board D. Actuating-mechanism is arranged so that at each depression of the handle C<3> or C<9> motion is imparted to the hammer E, Fig. 1, and to strip-feed and die-registering mechanism shown in Fig. 4. The pegs C<8>, Fig. 3, are formed on sliding grips C' carried on stems C<4> and limited by means of set-screws C<6> and slots C'. The hammer E, Fig. 1, is reciprocated in a bracket E' by means of a pin E<7> and a slotted arm E<2>, which is pivoted to an adjustable lug E<3> and to an arm F<2> secured to the strap F<1> of an eccentric F loose on a driving-shaft G. An adjustable divided clutch-band F<3> is connected to the eccentric F, and frictionally engages a flange or pulley G<2> secured to a driving-pulley on the shaft G. A trip-plate H on a spring-controlled bell-crank lever H<1> projects into the path of an arm F<7> on the eccentric F. The lever H<1> is also provided with a trip-plate H<5> and a pivoted lug or bearing H<4> for the free end of an operating- rod H<3> pivoted to an arm D<7> on a rocking-shaft D<5>, which is provided with other arms D<4> carrying a spring or gravity controlled lever or plate D<8> below the board D in position to be depressed by pegs C<8>. When the plate D<8> is depressed, the rod H<3> slides against the trip-plate H<5>, and turns the lever H<1> to withdraw the trip-plate H from the arm F<7>, and the further movement of the lever H<1> carries the rod H<3> clear of the trip-plate H<5>, leaving the lever H<1> free to be returned by its spring to the normal position, and thus ensuring that there shall be only one hammer blow for each depression of the plate D<8>. A registering or gripping bar J, Fig. 4, provided with a die notch or recess J<1>, projects into the bed groove, and is carried by a tube J<2>, which is free to slide in a tube J<3> in turn free to slide in a socket A<3>. A spring J<4> is interposed between the tube J' and a web J<5> in the tube J<3>, and a stronger spring J<7> is interposed between the socket A<3> and a collar J<6> on the tube J<3>. A serrated or roughened plate K<1> on the tube J<3> projects through a slot in the socket A<3>, and is engaged by a pressure foot K<3>, which is carried by a spring-retained pivoted arm K. A bell-crank lever L, Fig. 1, operated by an eccentric L<2> on the eccentric F, is connected by a spring L<3> to a pin K<5> on the arm K. The tubes J<2>, J<3>, Fig. 4, are cut away to receive a wedge or cam-shaped member adjustably linked to an arm J'‹, Fig. 1, on the eccentric strap F<1>. The wedge is operated before the hammer, and causes first the advance of the tube J<2> with the die-registering bar J, and then the advance of the tube J<3> with the plate K<1> for a differential strip feed. Weighted levers may be used in place of the springs J<4>, J'. One edge of the strip M, Fig. 4, is kept against one edge of a guide M' by means of an adjustable guide-plate and a flanged roller M<3> carried on an arm M<4> secured to a spring-pressed spindle mounted on the guide M<1>.
