SECOND ELEVATOR. FOR. TYPOGRAPHICAL I MACHINES Clay E. Murray, Davenport, Iowa, assignor to Linograph Corporation, Davenport, Iowa, at

corporation of Delaware Application August 16, 1937, Serial No. 15.93%

12 Claims.

The present invention relates to that kind of typographical machines in which one line of type is composed and cast at a time, and relates more particularly to the second elevator mechanism of Among the objects of this .invention are to conserve space; to provide a machine which will have exceptionally wide magazines for a given overall width of machine; to'

provide, in a machine of the character indicated, a safety mechanism which will prevent breakage in event the second elevator becomes blocked and unable to move; and such further objects, advantages, and capabilities as will hereafter appear and as are inherent in the construction disclosed herein. My invention further resides in the combination, construction, and arrangementv of parts illustrated in the accompanying drawings and, while I haveshown therein what is now regarded as the preferred embodiment of this invention, I desire the same to be understood as illustrative only and not to beinterpreted in a limiting sense.

In the drawings annexed hereto and forming a part hereof, I

Fig. 1 represents a front elevation of a fragmentary portion of a machine embodying my invention;

Fig. 2 represents the same structure in a dif ferent portion of its operative cycle; and 1 Fig. 3 represents the same structure in a still different portion of its operative cycle.

The face plate I is shown as having a projection 2 at one cornerthereof upon which the second elevator 3 is pivotally mounted at 4 and 5. The second elevator comprises ahead 6 anda pair of arms I and 8 by which the head-is supported and actuated. An arm 9 connects the arm 8 to the link In so that power may be transmitted to the elevator to cause the same to swing in a. substantially vertical plane in-a direction parallel to the magazines. The head 6 and the lower arm 1 are pivotally connected at H, while the head is pivotally connected to the upper arm 8 at l2. A pair of fingers l4 rise from the head. 6 and are slightly notched to receive the cross pin l2 projecting from the sides of the arm 8. Springs l3 are secured to the; fingers M and are somewhat bent to cooperate with the. pivot or cross pin l2 and the fingers I4.

A screw l5 furnishes an operative connection betweenthe arms 8 and 9 and makes possible the adjustment of the vertical swing of the elevator. A spring 16 furnishes means between the;

crank arm 9 and the arm 8 so that there will not be lost motion between these parts.

The matrices and space bandsare carried from casting position to the upper transfer position by the elevator slide I! provided at its upper end with the elevator-jaws 18. They are pushed forward into the intermediate box H! by the pusher l9a. The space bands are indicated at 20 while the matrices are shown in dotted lines at 2 l The ears of the space bands are longer than those of the matrices and, therefore, the latter may be lifted out of the intermediate box l9 by the head 6, as shown in Fig. 2. Before the matrices and space bands are transferred from the elevator jaws l8 to the intermediate box' l9, the head 6 assumes the position shown in Fig. 1 and is ready to receive the matrices 2|, the space bands 2|] being separated from the matrices by suitable mechanism, not shown. When the link It is pulled downwardly from the position shown in Fig. 1 toward that shown in Fig. 2', the head 6 is elevated but it is always maintained in a position parallel to theposition which it occupies in Fig. 1. Asthe head 6 moves upwardly, the matrices 2| are lifted away from the space bands 2|] and the latter are moved to the right ,by the shifting means 22 connected to the pusher I911 by the link I91) to be discharged into the space box 23. Here they are ready for use in the setting up of a subsequent line.

Since the pivots land 5 are fixed and are the same distance apart as the pivots II and i2, and since these four pivots define a parallelogram, a plane defined by the axes of the pivots l l and l2 must maintain a position of parallelism with any other position which this plane assumes. Therefore, the head 6 must, at all times, remain parallel to any position which it may occupy at any time during its course of travel.

If the head 6 should-become stuck or jammed for any reason, when in its lowermost position, so that it cannot rise when the link 10 is pulled downwardly, then the downward pull would causethe arm 8 to turn on its pivot 5, the pivot l2 being released from between the fingers l4 and the springs l3. Thus, breakage of. the machine because of the immovability of the head will not result. The operation of the machine.

will then be stopped and the cause of the trouble can then be located and removed.

When the second elevator reaches its uppermost position, illustrated in Fig. 3, the distributor shift lever 24 turns about its pivot, located at a point below any part of Fig. 3, andpushes the link 25 to the right to cause the head 26 to engage the matrices and shove them on to the bar 2'! of the distributor box from Which they pass to the distributor mechanism at the right and are re-distributed by the screw 28 to themagazine 29. This distribution is well understood by those skilled.

It is of course understood that the specific description of structure set forth above may be departed from without departing from the spirit of my invention as set forth in this specification and the appended claims.

Having now described my invention, I claim:

1. In a typographical machine, a support, a matrix elevator pivotally mounted thereon, said elevator comprising a head and a compound headlifting arm, said arm comprising a pair of individually pivoted arms mounted on said support for united or separate swinging motion in a substantially vertical plane, said head having fingers projecting therefrom and pivotally connected to the free ends of said individually pivoted arms, the upper one of said pair of arms having a crank arm whereby force may be applied to it to cause it to turn about its pivotal connection to the support, the pivotal connection of the upper arm to said fingers being such as to normally cause the head to swing with saidupper arm but such as will permit the head and arm to separate if the head becomes locked in any manner and unable to swing with the arm.

2. A structure as defined by claim 1 in which the pivots of said compound arm define a parallelogram so that the head, during its movements, will always occupy positions of mutual parallelism.

3. In a typographical machine, a support, a matrix elevator pivotally mounted thereon and swinging substantially in a plane defined by a magazine of the machine, said elevator comprising a head and a compound head-lifting arm, said arm comprising a pair of individually, pivoted arms mounted on said support for united or sepa rate swinging motion in a substantially vertical plane, said head having fingers projecting therefrom and pivotally connected to the free ends of said individually pivoted arms, an intermediate box, and a distributor box, said head cooperating with said boxes, and said compound arm carrying said head from a position in which it cooperates with one of them to a position in which it cooperates with the other.

4. In a typographical machine, supporting means for the movable mechanisms of the machine, an intermediate box carried thereby, a distributor box, a matrix transferring head cooperating with said boxes, 9. parallelogram arm having two pivots connecting it to said supporting means and two connecting it to said head, mechanism for swinging said arm to raise and lower said head, the arm swinging in a plane substantially parallel to the plane of a magazine in position for use.
