GEORGE P. KINGSBURY, OF HOLLIS, NEW YORK, ASSIGNOR TO MERGENTHALER LINO- TYPE (JOTVUPANY7 A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

Application filed April 21, 1928.

This invention relates to typographical machines, such as linotype machines of the general organization represented in U. S. Letters Patent to O. Mergenthaler No. 436,532, wherein circulating matrices are released by escapements from a magazine or magazines in the order in which t-heir characters are to appear in print and then assembled in line, the composed line transferred to the face oi' a mold, the mold filled with molten metal to form a slug or line of type against the matrices which produce the type characters thereon, andthe matrices thereafter returned through a distributing mechanism to the magazine or magazines from which they started.

In these machines, the magazines are usually mounted in such manner that they may be quickly removed and replaced by other magazines containing ditlerent matrix fonts. Before removing a magazine, however, it is customary to lock the matrices therein; in fact, this is 'necessary when the escapements are separated from the magazine, as otherwise the matrices would be free to escape therefrom. Hence, the commercial machines are equipped with devices which prevent the removal of the desiredmagazine until thematrices have been lirst locked therein. In some instances, as when the magazine is lifted out of engagement with the escapements, the locking devices are arranged to prevent the premature raising of the magazine 5 while in other instances, as when `theescapements are lowered out of operative relation to the magazine, the locking devices are arranged to prevent the movement of the escapements as distinguished from that ot the magazine. In either case, the locking devices referred to are controlled and actuated by matrix locking means which, in locking the matrices in the magazine, release it for removal. There are two kinds of matrix locking means now in use, one being in the form of a detachable bar which is inserted and removed endwise through the edge of the magazine, and the other being in the kform of a permanently attached bar mounted on the magazine so as to be movable instantly to active or inactive position.

The present invention contemplates a matrix locking bar of the permanent type which not only presents all the advantages of those now in use but may be produced at a minimum cost to the manufacturer and is readily Serial No. 271,734.

movement in its active and inactive positions. n

In the accompanying drawings, the invention has been shown merely in preferred form and by way of example but obviously many alterations and variations may be made therein and in its mode oi application which will still be comprised Within its spirit. It is therefore to be understood that the invention is ynot limited to any specific form or embodiment except in so far as such limitations are specitied in the claims. v

Fig. 7 is a detail end view of the bar and its operating handle, showing the relation of the former to the matrices in its active and inactive positions; and

Fig. 8 is a detail view of theopposite end of the locking bar.

The matrices X (see Fig. l) are stored in the standard magazine A and are released, one at a time, under control of the escapements B which are actuated in the usual way from the regular keyboard mechanism, not shown. The magazine A comprises, as usual, the upper and lower grooved plates A1, A2 and the right and left-hand side barsA3,iL 1,which latter are provided near their lower ends with the customary transverse cuts or recesses A5, AG. At the front, the respect-ive plates A1, A2 are extended by means of the heavier plate sections A7, A8 which are also fastened to the side bars A3, A, the upper section A7 being adapted to accommodate the matrix locking device, and the lower section AS being recessed and apertured to receive the grcoved portions of the escapement supportin bar D1.

In the embodiment illustrated, the escapement bar B1 is carried by the magazine base frame C, and the magazine is mounted so as to be capable of being lifted out of engage ment therewith preparatory to its removal. Consequently, the safety locking device herein employed is associated with the magazine rather than with the escapements and is intended to prevent raising of the former until the matrices have been locked therein. This device is arranged, as usual, at the left of the magazine adjacent the side bar A4 and consists of a latch member or lever D'which is disposed in the longitudinal plane of the magazine and pivotally mounted in a suitable bracket D1 fastened to the base frame C. A light compression spring D2, seated in the bracket D1 and engaging the latch D, serves to maintain the latter resiliently in its active position, the rear end thereof at such time being directly opposed to a linger E which is adapted to be swung forwardly as the magazine is lifted out of engagement with the escapements B. The linger E is secured to a rockshaft E1 journaled transversely in the base frame C and provided about midway its lengthwith a rectangular cam plate E2 which is normally disposed in the plane of the base frame C in position to directly engage a longitudinal bar A3 fast to the magazine ribs A10. As thus arranged, by rocking the shaft E1, the cam plate will be swung upwardly and downwardly and, through its engagement with the bar A3, will raise and lower the magazine relatively to the base frame and the escapement bar B1 (see the dotted line showing in Fig. l). Rocking of the shaft E1 is effected, usual, by means of a pair of manually operable side arms E3 which are detach ably mounted on its opposite ends and may be locked thereto in any suitable manner in-order to obtain the purchase required. These arms are adapted to bank upon lateral projections C1 of the base frame C when swung forwardly to raise the magazine and, in this position, serve not only to support the magazine during its removal but also to facilitate its replacement. The foregoing parts and their mode of operation are similar to those incorporated in the com mercial linotype machines and in themselves constitute no part of the present invention, but for further information reference may be had to the h/.lcNamaI-a Patent No. 1,586,316.

The present invention is directed specilically to improved means for locking and releasing the matrices in the magazine A and to the manner in which it is adapted to control the operation of the magazine lockin device D. Such means, in the preferred embodiment illustrated, consists of a locking bar F provided at its opposite ends with trunnions F1, F2 journaled in the upper plate section A?.

Leeaaia To permit the assembling of these parts, the plate section A7 is provided at one end witha split bearing formed by a block A11 and adapted to receive the trunni ons F1 F. This block A11 fits against the right-,hand end of the plate section A7 and is rigidly clamped upon the magazine side bar A3 by the two screws ordinarily employed to secure that side of the top plate section. For reasons presently to appear, the block A11 is provided with a spring detent A12 disposed parallel to the locking bar and it is ralso formed with a transverse slot A13 offset at A11.v As shown in the drawings, the form and arrangement of the bar F is such thatit is adapted, when roof the bar tated through a limitednumber of degrees in a clockwise direction (accordingto Fig. 7), to stand clear of the matrices in the magazine and, when given a similar turn in the opposite direction, to engagethe upper ears of the mat ricos and pushthem slightly back out of en `gagement with the escapement -pawls In the latter or active position of the bar, the mat-V rices are locked thereby against escape from the magazine A.

Rotation of the locking bar, in the present instance, is accomplished by means of a small operating handle F3 keyed to the trunnion F1, and having a hub portion F4 formed with a short radial arm F5, the latter being disposed approximatelyr at right angles to the shank portion FG of said handle and located in a plane offset slightly therefrom. ln the inactive position of the bar F (seeFig. 3) the handle F3 is raised and the shank portion FG thereof lies flush against the outer side face of the bearing block A11 where it is maintained yieldiirglyy by the spring detent A13. When .the bar is turned to its active position (see Fig. 5), the shank portiony FG of the handle F3 is .first brought into registry with the slot A13, above mentioned, where it is arrested by a stop shoulder a formed on the block A11. This operation also .swings the radial arm F5 upwardly into horizontal alinement with the detent A13. As before stated, the bar F is not only rotatable to lock the matrices in the magazine but is also capable of a limited endwise movement to actuate the latch D. The block A11 is, therefore, counter-bored to receive the hub portion F4 of the handle,

and the bar proper between the trunnions F1,

F2 is made somewhat shorter than the distance between the inner side walls of its bearings.

Hence, when the handle is in registry with the slot A13, the bar is capable of being` slidbodily endwise back and forth in its bearings.

As best shown in Figs. :2, 3, an dll, the front i ranged to engage the latch below the rounded or beveled corner d thereof. When the bar is pushed all the way to the left to actuate the magazine latch, the shank F 6 of the handle F 1 is vertically alined with the notch or offset portion A11 of the slot A13 and may then be lifted into engagement therewith to lock the bar against endwise movement. In this connection, it should be understood that suflicient lost motion of the bar in its locking position is necessary to permit such axial movement thereof to take place without disturbing its purchase on the matrices. As theshank of the handle enters the notch A14, the detent A12 engages a recess in the short radial arm F 5 and thus maintains the bar F in its locked position (see Figs. 4, 5 and 6).

From the foregoing, it. will be'seen that, when the bar F has been pulled to the right against the inner wall of its right-hand bearing, it may be turned to active or inactive position as desired, according to the direction of movement of the operating handle Ff". In the inactive position'of the bar, the handle F3 is raised alongside the outer face of the bearing block A11 and locks the bar against endwise movement. In the active position of the bar, on the otherhand, the handle stands opposite the slot A11 and allows the bar to he pushed to the left, in which position it may bey locked against endwise movement by turning the handle upwardly to cause its shank F6 to enter the offset portion A14 of the slot A13. The detent A12 serves, in both its active and inactive positions, to restrain the bar against accidental rotation. Since endwise movement of the bar is permitted only when it is in act-ive position, any damage that might occur for failure to lock the matrices before the release of the magazine is avoided. It is also pointed out that, inasmuch as the extent of the endwise movement of the bar F in operating the magazine latch D is greater than the distance between the inner walls of the magazine side bars and the adjacent columns of matrices, the arrangement must be such as will permit rotation of the bar in overlapping relation to said bars in order that all of the matrix columns may be engaged whether the bar occupies itsV position at the left or right. For this reason, and as will be seen from Figs. 3, 4, and 5, the locking bar, in the present instance, is preferably arranged in definite relation to the regular transverse cuts or recesses A5, A6; that is to say, the axis of the bar F is located centrally above these cuts so as to provide the necessary clearance without changing the construction of the standard magazine.

l/Vhile the operation of the yparts will have been understood from the foregoing description, a brief recapitulation may be helpful. Preparatory to removing the magazine A, and assuming the matrices to be unlocked, the handle F3 is disengaged from the detent A12 and, by the same'operation, turned downwardly against the 'stop shoulder a. The bar F is thus rotated to its active position and is now free tobe pushed to the left until the hub portion of the handle comes in contact with the right-hand bearing. rIhe handle is then lifted slightly to lock the bar and permit the detent A12 to snap into engagement with the radial arm F5 (see Figs. 4, 5, 6, and'). The matrices X are thereby locked against escape and the trunnion F2 at the left will have engaged the magazine latch D and rocked the upper end thereof out of the path of the upstanding finger E. The magazine E3 and cam plate E2, out of engagement with the escapements B to removing position (see dotted lines Fig. l). As the magazine is raised, the trunnion F2 is disengaged from the latch D and the latter is allowed to resume its normal locking position under action of the spring D2. Vhen the magazine is lowered, however, the stud 7*' on the end of the trunnion F2 will engage the beveled corner d of the latch D and, by such engagement, vcam the latter out of the way so that the magazine may properly reengagethe escapements B. After the magazine comes to rest on the base frame C, the handle F3 is disengaged from the notch A1, pulled toward the right to draw the bar F out of engagement with the latch DI and cause` it toy lock the magazine against removal, and finally turned upwardly until engaged by the detent A12 to restore the bar to its inactive position.
