Granted: 1899-09-02
Abstract: 13,328. Krull, J. H. F. June 27. Sale apparatus, principally for tickets. Fig. 6 shows a diagrammatic view of the electromagnetic arrangements comprised. Delivery mechanism; coin action; coin-discharging mechanism.-The bottom article of a pile is thrust out of the casing by a slide which reciprocates with an oscillating armature d. Normally the armature is in the position shown, and the electromagnets a, b have a residual polarity tending to so retain it. The coin arriving between a fixed contact n and a pivoted one l<1> completes the circuit p, q, whereupon the polarity of the electromagnets is strongly reversed and the armature swings over to the left, delivering the ticket. An arm e moving with the armature completes the circuit r of a small electromagnet l, which lifts the pivoted contact from the coin, so breaking the main circuit. The coin drops again to a second pair of contacts m', o, and completes the current p, p<1>, q<1> of the main electromagnets. The armature is consequently brought back to its initial position, and the arm e moving with it momentarily makes the circuit of a second small electromagnet m, which sets the coin free. In a modification, mercury and spring pin contacts are used, and there is an arm approximately horizontal to close them together. Tickets, printing; coin action.-The tickets may be stamped as they are delivered, a lever bearing a stamping-roller being operated by an electromagnet. As the coin is inserted mto the apparatus, it presses a lever 14 having a notch 16 to draw a flexible terminal 19 into contact with a stiff one 18.

Title: Improvements in Mechanism for Tripping the Cylinders of Double Cylinder Sheet Printing Machines; especially applicable to Two Revolution Cylinder Sheet Perfecting Printing Presses.
Inventor: MIEHLE ROBERT
Filed: 1901-12-19
Granted: 1902-02-27
Abstract: 25,980. Miehle, R. Dec. 19. Cylinder machines with plane printing- surfaces.-Relates to mechanism for tripping the cylinders of two-cylinder machines. The cylinders are raised by springs on the rods B<3>, C<3>, and are depressed into the printing position by depressing the rods. The rods are provided at their lower ends with crossheads B<4>, C<4>, acted upon by eccentric arms G', G<1a> on shafts G, G<a> actuated by gearing E<5>, E<6>, E' in unison with the cylinders. The shafts G, G<a> are normally operated by cams L, L<a> on the wheels E<5>, E<7>. The cams engage the pins L<1>, L<1a> on arms J, J<a>, loose on the shafts G, G", and having pivoted on their ends gab hooks K, K<a>, the notches of which engage arms g, g<a> fixed on the shafts G, G<a>. The gab hooks are lifted, to trip the cylinders, by cam-levers M, M<a>, each of which is connected to a treadle-lever M<2>, M<2a>, by which it may be operated independently, so that either cylinder may be tripped. The cam-grooves m, m<a> of the levers M, M<a> normally permit of the movements of the projections K', K<2a> on the gab hooks while the hooks remain in engagement with the arms g, g<a>, but, when a lever M or M<a> is raised by the operation of its treadle, the projection engages the cam portion m<1> or m<a>, and the g<ab> hook is lifted so that it is disengaged and in its next movement slides over the end of the arm g or g<a>. The hook K has a second shoulder K<3>, which engages the arm g and depresses the corresponding cylinder sufficiently for the bed and cylinder gear to engage, but not to make an impression. A pivoted catch P engages the shoulder P' of the cam-lever M<a>, when the latter is operated by its treadle, and holds it, so that the treadle may be released before the hook K<a> is operated. The arm J<a> on moving to the left disengages the catch P. The treadles are so arranged that either may be held depressed by moving it into engagement with a slot in the framing. The treadle operating the levers M<2>, M has a side arm which engages the other treadle, so that the depression of the first may operate both.
