  • This invention relates to typographical machines, such as Linotype machines of the general organization represented in Letters Patent of the United States No. 436,532 to O. Mergenthaler, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then composed in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug against the matrices which produce the type characters thereon, and the matrices thereafter elevated and returned through distributing mechanism to the magazine from which they started.

  • Each of the magazines is provided with a series of-rnatrix releasing escapements D which, when the selected magazine is brought into operative position, are actuated under control of the keyboard mechanism in the usual way.
  • Each base frame is provideduwith a central magazine lifting and supporting plate E (see particularly Fig. 5) which is substantially as long as the base frame itself and which is located in a corresponding groove or recess E formed in the upper side of the base'frame.
  • the plate E is pivoted to the base frame, as at E thus permitting it to be swung upwardly in liftingthe magazine; and at its lower end it is provided with a stop shoulder E normally engaged in a transverse notch formed in the bottom face of the customary long center bar a on the undersideof the magazine and which thus retains the magazine in place on the plate when the latter is in its raised position.
  • the long center bar a on the magazine is located in a corresponding groove E extending throughout the length of the plate 'E. whereby the magazine is guided in a longitudinal direction as it is removed from or applied to the plate during removal or replacement.

  • the guide piece E is formed with a centrally located notch E (flared at its forward side) registering with the groove E in the plate E to accommodate the long center bar a. on the magazine.
  • the magazine lifting and supporting plate E is provided at its forward end, just in advance of the stop shoulder E with an automatic looking device in the form of a transverse plate L attached to the front face of the guide piece E by cap screws L passing through elongated slots L the screws L serving also as the means of attachment of the guide piece to the plate.
  • the locking plate L is formed with a notch L which, in the magazine releasing position of the plate, registers with the flared notch E in the guide piece E to accommodate the long center bar a. of the magazine.
  • the plate L is formed with an overhanging lug or hook L which, in the magazine locking position of the plate, is adapted to overlie the long center bar a of the magazine and prevent its disengagement from the stop shoulder E on the plate E (see dotted lines in Fig. 3) but which, in the magazine releasing position of the plate, is adapted to stand clear of the center bar a and permit its disengagement from the stop shoulder E (see Fig. 2).
  • a small compression spring L housed in a recess formed in the left end of the guide piece E and reacting against a nose L5 formed on the plate L.
  • the plate L when the magazine is moved into position for removal, the plate L will be moved to and held in its magazine releasing position, against the action of the spring L by the lug F on the lifting cam F, as shown in Figs. 2 and 3.
  • the nose L is formed with a cam surface L which is engaged by the lug F just before the cam F reaches its final position, the pitch of this cam surface being sufficient to move the plate L from its magazine looking to its magazine releasing position.
  • the locking plate L will act at all times to hold the magazine in place upon the lifting and supporting plate E exceptwhen that plate occupies its upwardly swung position and when the magazine supporting arms K are in position to receive and give support to the magazine after its disengagement from the stop shoulder E. It will also be seen that after the replacement magazine has been placed on the plate E and engaged with the stop shoulder E the locking plate L will be allowed to return to its locking position, under the influence of the spring L the instant the lug F passes onto the cam surface L during the initial movement of the cam F in lowering the plate E back into position upon the base frame.
  • the magazine supporting arms K remain in magazine receiving position, so that if by any chance the locking plate L were not allowed to act (due, for instance, to the improper seating of the magazine upon the plate E), no serious damage could result. But, once the magazine is properly seated on the plate E, the locking plate L becomes almost immediately effective and guards against any danger of the magazine being lifted-acoidently or unintentionally from the plate E during the lowering movement thereof. And, of course, the locking plate L continues to exercise its safety function after the magazine has been lowered into place upon its base frame and despite any lifting force which might be exerted on the magazine, for one cause or another, during the movement of the shift frame in changing magazines.
  • the magazine lifting and supporting plate E is provided with an automatic locking device in the nature of a detent M slidably arranged in a. transverse recess formed in the upper face of the plate E to the rear of the guide piece E
  • a cover plate M attached by screws to the plate E holds the detent in place and permits ready assembly of the parts.
  • the detent is designed to overlie the bottom wall of a semi-circular recess a formed in the upper face of the long center bar a on the underside of the magazine.
  • the detent At its outer end, the detent has a depending lug M which limits its inward movement and which is formed with an inclined slot M engaged with a pin M rising from the rear end of a fore-and-aft actuating slide M arranged in a recess formed in the under face of the plate E.
  • the slide M is held in place by a pair of cap screws M passing through elongated slots M formed therein.
  • a short tension spring M pulls rearwardly on the slide M and serves constantly to move it toward the rear and, -throughthe pin and slot connection M M to :maintain the detent M in its magazine locking position, as shown in all three figures.
  • the movement of the detent M to magazine releasing position is effected, as in the first embodiment, by the magazine lifting movement of the cam F.
  • the notched lug F is utilized for the purpose, this being accomplished by attaching the stop pin F to the slide M rather than directly to the plate E.
  • additional means are provided in this second embodiment to prevent the magazine lifting and supporting plate E from being lowered unless the magazine ha been properly seated thereon, that is to say, unless the long center bar a on the magazine has been properly engaged with the stop shoulder E on the plate E.
  • Such means consist simply of a small plate N attached to the rear edge of the notched lug F and extending a short distance beyond it so as to engage the lug M on the locking detent M whenever the detent fails to return to its locking position during the initial downward movement of the cam F.
  • Such a condition will arise if a magazine is not properly seated on the plate E, since the detent M will be blocked against inward movement by engagement with an unnotched part of the magazine bar a.
  • the magazine bar a is seated properly in the groove E of the plate E, the semicircular recess a will be in position to receive the detent and the lug M will stand out'of the path of the plate N.
  • the outer face of the lug M is shown as inclined although it need not be.
