TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed. July 15;l 1916. Serial No. 109,452.

vof New York, have invented certain new and useful Improvements in Typographical Machines, of which the' following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotype machines of the general organization represented in United States Letters Patent to O. Mergenthaler, No. 436,532, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through distributing mechanism to the magazine from which they started. More particularly, it relates to machines of the kind disclosed in the Letters Patent of D. S. Kennedy, Nos. 1,193,558 and 1,193,559, and his pending application Serial No. 52,999, and other of his patents and applications `unnecessary to refer to herein.

In these machines, the matrices are stored according to font in a plurality of magazines, each provided with its own series of escapements which eiiect the discharge of the contained matrices inthe required order. Theseveral series of escapenients are controlled by a common set of actuating reeds, which tend to actuate the corresponding escapements of all the series at each operation; but such simultaneous actuation of the escapemcnts is prevented by locking devices, one for each series, which are controlled by magazine selecting keys in suoli manner that when one locking device is moved to inactive position, the others are simultaneously restored to active position, thus permitting the delivery of matrices from one magazine only at a time. Further, in these machines, the escapement actuating reeds are carried by a frame or :so-called front plate, which is pivotally supported so as to be swung forwardly to give access to the interior parts, this movement of the frame at the same time disconnecting the actuating reeds from the escapements. Means are also provided,

when or before the frame is thus swung forwardly, for restoring the escapement locking devices to active position in order to prevent the release of matrices from the magazines due to ,the disconnection of the actuating reeds from the escapements.

It has been found 11i practice that under certain conditions, an escapement locking device will fail to return to active position,

as, for instance, when one of the escapeinents is caught by a matrix improperly located in the magazine. In such event, the escapes ments of the series remain unlocked when the actuating reeds ai'e disconnected therefrom, thus allowing the lowermost matrices to escape from the magazine with the evil results which necessarily follow.

It isthe object of my present invention to obviate these objections, and to that end 1 have provided each series of escapements l with locking means which will operate in the above circumstances to hold them against action even though one of them occupies an abnormal position at the time. In one of the embodiments illustrated, I have modified the escapcments and their key-controlled locking devices so that thel latter may be moved to active position notwithstanding the abnormal location of one or more of the escapements; and in another embodin'ient, I have provided each series of escapements with a supplemental locking device which will serve to hold them in locked condition in the event that the usual l ey-controlled locking device fails to act. In this latter embodiment, means are provided whereby the supplemental locking devices are moved to active position automatically when or before the front plate is moved. In this way the locking of the escapemcnts is insured at all times, and even though one of them should be caught by an oifeuding matrix.

In the accompanying drawings I have illustrated my improvements merely in preferred form and by way of example, and obviously many changesI and variations may be made therein which will still be comprised within the spirit of my invention. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

As my improvements have been embodied in a machine of the kind disclosed in the Kennedy application, Serial No. 52,999, before referred to, I have confined the drawings to such parts thereof as are imine.

diately concerned. If desired, reference iiiaybe had to said application for a further land complete illustration and description of A,the remainder of the machine.

Referring to Fig. l, the matrices X are Ystored according to font in one or the other of the magazines B, only two of which are shown, but of which a greater number might be employed if desired. The matrices are released from their corresponding magazine by the escapeinents C and pass through one or the other of the throats D1 into the vertical channeled raceway D whence they are carried to the assembler and composed in line in the customary way.

The escapements C are of the usual construction, each comprising a rocking lever and a pair of paivls, which latter are projected alternately into the corresponding magazine channel to control the release of the contained matrices. The escapemeiits for each magazine are supported iii series in the bar or frame CS, which may be connected directly to the magazine, or, (as in the Kennedy application) pivotally secured to the magazine base-frame. The escapements of both magazines are coiitiolled by the single series of actuating members or reeds C2 formed with the rearward projection C overlying the forward arms of the small levers C1, pivoted to the lescapenieiit supporting frames CS, and which under the influence of the members C2 act to rock the corresponding escapenients of the two magazines.simultaneously in one direction against the force of the springs Cu1 tending to rock them in the opposite direction.

Attached to the lower ends of the actuating members C2 are the spring C3 pulling downwardly thereon from a relatively fixed part of the machine and of sufhcient strength to overcome the action of the springs C4, so as to holdthe lowermost pawls of the escapenients in engagement with the leading matrices in the magazines, which are thus prevented from escaping therefrom. Toi permit the release of such matrices, therefore, it is necessary to raise the actuating members C2 against the force of their springs C3, when the lighter springs C* will be allowed to act; and this movement of the actuating members is effected by the pivoted levers G5 engaging beneath the projections C12 thereon and arranged to be rocked upwardly by the vertically guided rods C6 operated from the keyboard mechanism in the usual way.

Since the actuating members (i1 control the escapements of both magazines, their operation would result in the release of matrices from both at the same time were other means not provided. Each series of escapements, therefore, is equipped with the well-known transverse rock shaft H which is rotatably mounted in the supporting frame C8 and arranged in proximity to the rear ends of the escapenient levers, the shaft being cut away or recessed in the usual way so that in one position it will lock the escapements against operation, while in another position it will permit their operation. The two rock shafts H are provided at one end with crank arms (shown in dotted lines) which are connected by the vertical rods Hi to the pivoted levers H6 operated througli the medium of the rods `H7 by the cam yokes HS controlled in the usual way by the magazine selecting keys H10 disposed alongside the main keyboard. The rods H1 are constantly urged upward to move their rock shafts H to locking position by the springs H5, and are held .down against the action of the springs by the hooks H12 projecting upwardly from the locking plate Hn and adapted to engage over the rear arms of the levers H6 when they are rocked downward by the actuation of the corresponding magazine selecting keys (see Figs. l and 1b). The locking plate H11 is normally held toward the right in Fig. l1 by the spring H9 with the inclined ends of its hooks H12 in the path of the levers H, so that as one or the other is rocked downward it displaces the locking plate toward the left and passes beyond the corresponding hook, which then immediately snaps across the lever and holds it depressed with the .connected rock shaft H in unlocking position. It will be noted that the disiso placement of the locking plate by one of the levers H6 releases the other, if the latter had previously been locked down, and consequently permits the connected rock shaft to be returned to its locking position by the spring H5. In other words the arrangement is such that the alternate actuation of the two keys H1o effects the movement of the rock shafts H to locking and unlocking position alternately, so that but one series of escapements C is allowed to be operated by the actuating members C2 at a time and consequently matrices released only from the corresponding magazine.

The escapement actuating members@2 and the other devices are all mounted upon the pivote-d frame or front-plate G, (shown only in pal-therein) which may be swung outwardly away from the magazines to permit their removalor to give access to theinterior mechanism. Before or when this swinging of the frame G is effected, the rock shafts H should be restored to active position, as otherwise (due to thedisconnection of the actuating members C2 from the escapements) the latter would beactuated by the springs C4 to release the lowermostmatriees in the magazines. The means employed to secure this result are the same yas illus`` trat-ed in the above-mentioned Kennedy application Serial No. 52,999, consisting of the long lever H13 connected to the locking plate H11 and fast to the rearend of the fore-andaft rock shaft H15, which is provided at its opposite end with the arm H16 arranged in position tobe engaged by the arm H17 secured to one end of the cam bar H1s rotatably mounted in the swinging frame G and coperating with'rthe rearward projections C13 on the escapement reedsCz, so that when rotated it will raise the latter and disconnect them from the several series of escapements C prepara-tory to the outward movement of the frame. At its opposite end the cam bar H18 (Fig. 2) is provided with an arm H30 connected by means of a long link H31 to a crank arm H32 fast to the stub shaft lon which is mounted the operating handle H33 provided with the cam or eccentric H35 which is adapted to engagea part of the fixed machine frame and lock the swinging frame G in operative position. The lever H13 is normally urged toward the lcftLTig. lb) by the spring` H14, which is of sufficient strength to overcome the antagonistic spring 'H9 of the locking plate H11 and to move the latter to unlocking position. Normally, however, the lever H13 is held toward the right by the cam bar H18 through the inter.- mediate connections described, so that the spring H14 is not allowed to act, but when the cam bar is rotated by the unlocking of the frame Grv its connections with the lever H13 are brokenv and the latter, therefore, un? der the infiuence of the spring H14, is caused to move the locking plate H11 to inactive position. The effect of this arrangement is that either rock shaft H, which may be standing in inactive position at the time, will be restored to active position when the frame G is unlocked preparatory to its movement outwardly from operative position.

Fig. l shows the parts in a normal position with the swinging frame Gr locked against movement, and with one of the rock shafts H in inactive position and the other .in active position. lf, now, it should be desired to draw the frame G forwardly, the operating handle H33 is rotated to the position shown in Fig. 2 in the direction of the arrow there indicated, thus unlocking the frame G and through the connection described releasing the rod H4 connected to the particular rock shaft in unlocking position, (in Fig. l the rock shaft for the upper magazine) which is then immediately restored to locking position by the spring H5. The parts so far described and their manner of operation are fully set forth in the aforesaid Kennedy application 52999, and the corresponding parts are indicated by substantially the same letters of reference.

It may happen Vthat for one reason or another the return of the rock shaft H to active position, as above described, will be prevented, as when it is engaged with an escapement which is caught by a matrix improperly located in the magazine. Thus, in Fig. l, one of the escapements for the upper magazine'is shown as having its lower pawl held out of the magazine by a matrix which has passed beyond its proper location, causing the escapement to occupy an abnormal position, or one which is the reverse of that it should occupy; namely, with the upper end of the cscapement lever held close up agaiinst the rock shaft H, thus locking it against rotation. (lonsequently, when the frame G is to be swung forwardly, the release of the rod H41 fails to restore the connected rock' shaft to active position, (the signing H5 yielding) and the lowermost matricosV in the upper magazine may fall out into the fmachine, since the actuating reeds C2 are disconnected from the escapements by the unlocking and the movement of the frame, and the escapements are thus allowed to be op :ated by the springs G4',

`This diliiculty is avoided according to my invention by the provision of va supplemental locking device for each series of escapements, which serves to hold them against ac tion in the event. that the rock shaft H fails to do so, and which, preferably, is operated automatically as the frame G is unlocked to be swung forwardly. In the present in stance, (sce particularly Figs. 2 6) it is in the form of a thin transverse strip or plate c, arranged to cooperate with upstanding lips c1 on the upper edges of the escapemeut actuating levers C1, The plate c is attached to the escapement supporting frame CS by means of inclined pin-and-slot connections c2, of such character as to cause the plate to be moved edgewise upwardly and downwardly as it is shifted longitudinally to the left and right respectively. A spring n* (see Figs. 3 and 4:) tends constantly to hold the plate in its leftmost position, where it will stand (as shown in Fig. l) some distance above the lips c1 on the pivoted levers G1, which may thus be operated freely. When, however, the plate is shifted to the right, its lower edge is brought down into engagement with the lips c1 and locks the levers G1 against rotation (as shown in Fig. 2), the plate being held in vthis position by a spring-actuated detent cs, which is seated in a recess in the escapement frame and is provided at its forward end with a reduced portion c adapted to pass through a hole or opening 011 in the locking plate. The locking of the actuating levers C, due to their engagement with the escapements, consequently locks the latter in their normal position against the action of the springs c". To release the parts, it is merely necessary to disengage the detent, it being provided with a projecting pin 01 for this purpose.`

The shifting of the plates c to the right is effected by means of small latches c5 pivoted to bracket plates 0G, one of which is secured to the inside face of the long link H31, and the other to an upward and rearward eXtension H34 thereof. The link Hf, it will be remembered, constitutes a part of the connections between the locking means for the swinging frame G and the locking devices which hold the rock shafts-H in inactive position, the connections being such that the link is moved upwardly and downwardly as the frame G is unlocked and locked respectively. The upward movement ofthe link H31, thus effects the raising of the latches c, which, by their engagement with the left ends of the locking plates c, (which are beveled or inclined at such ends) shift or cam the plates to the right against the action of the springs c. Thus, the parts normally occupy the position shown in Figs. 3 and 4, with the plate c located to the left and with its inclined end overlying the latch c5. When now the latch is moved Vupwardly, it engages the beveled end of the plate and shifts it to the right, as illustrated in Fig. 5, this movement of the plate also causing it to be depressed edgewise into operative position, the detents @s are disengaged from the locking plates by means of the protruding fingers 010, so as to allow the plates to resume their normal inactive positions to the left. When so located, however, the plates would stand beneath the latches c5 and interfere with the downward movement of the arm H31, which takes place when the frame G is locked or relocked in place. For this reason, each latch is arranged to yield upwardly, (see Fig. 6) as the arm H31 is depressed, the latch thus being free to pass the locking plate and thereafter to fall back into its horizontal position beneath the inclined end thereof.v

The operation of the parts will have been understood from the foregoing'description. Ordinarily, when the front plate is swung forwardly, the rock shafts H are returned to active position, and in such event, the escapements are\locked by two different instrumentalities. It may happen, however, that the rock shafts H cannot return to their active position, as when one of the escapements is caught in the manner illustrated in connection with the upper series in Figs. l and 2, and in such event theisupplemental locking device serves alone to hold the escapements against action. In this connection, it will be noted that the locking plate is free to be moved to its active position even though one of the escapements should be caught. For instance, as shown in Fig. l, when one of the escapements is caught, the upstanding lip c1 on the corresponding actuating lever C1 is located to ,one side of the locking plate and out of its path of movement, so thatit may pass therebeyond and into locking engagement with the upstanding lips on the remaining actuating levers, as illustrated in Fig. 2.

The effect of the above arrangement, therefore, is that the escapements will always be locked against action whenever the frame G is swung forwardly from its operative position. The locking of the escapements indirectlyresults in the locking of the matrices in the magazine, so that, more broadly speaking, the effect is that the escape of the matrices from both magazines is always prevented when the frame G is moved.

Figs. 7, 8 and 9 illustrate an alternative construction wherein the supplemental locking devices are controlled entirely automatically, means being provided for shifting them both to active and inactive position as the frame G is unlocked and locked, respectively. It will be noted that the plates c are still retained, being connected to the escapement supporting frames as before by pin-and-slot connections, by means of which they are moved edgewise when shifted longitudinally. In this instance, however, the slots are inclined in a direction opposite to that shown in the first form so as to cause the plates to move downwardly instead of upwardly as they are shifted to the left, and to move upwardly instead of downwardly they are shifted to the right. As a'result, the plates are held normally in locking position under the action of the springs 04, which tend constantly to move them to the left, so that to permit the operation of the escapements theplates should be held to the right against the action of the springs. This is secured by providing the connecting link H31 and its extension H34 with set screws or abutments c13 which are arranged to engage and actuate the plates as the link is moved upwardly and downwardly in effecting the unlocking and locking of the swinging frame G, respectively. Thus, as shown in Fig. 9, when the frame G is locked in position an abutment 013 stands in engagement with the left end of the corresponding locking plate c, and holds it to the right in inactive position. When, however, the frame is` unlocked, the upward movement ofthe link H81 carries the abutment cl3 upwardly therewith out of engagement with the locking plate, which is then shifted to the left by the spring c4, and thus caused to assume its locking position, see the dotted lines in` Fig. 9. When the frame Gr is relocked, the abutment cl3 is carried downward byr the movement of the link H31, and, by its engagement with the inclined end of the locking plate c, shifts the latter to the right, causing it to resume its original or inactive position. In the present instance, the bottomedge of each plate c is formed with a depending flange '012 adapted to engage in notches in the rear upper corners of the lips 01 on the escapement actuating levers C1 so as to become interlocked with the latter and positively hold them against pivotal movement. The general operation of the parts has been described before and need not be repeated here. In both forms, the supplemental locking devices are moved automatically to active position when or before the frame G is swung forwardly, and the second form differs essentially from the first only .in the respect that the locking devices are also moved automatically to inactive'position when the frame is restored.

Figs. l0 and 11 illustrate aA modification of my invention. In this embodiment, the supplemental lockingdevices and associated parts before described have been dispensed with, and the escapements C and their cooperating rock shafts H have been modified so that the shafts may be moved to active position even though one of the escapements should at the time occupy an improper or abnormal position. As seen in these figures, each of the escapement 'levers is of hookshaped form at its rear-end, so asl to present in its upper edge a recess Ca and an overhanging lip Cb; and each of the rock shafts H is formed with a longitudinal groove h2 which leaves at one side a longitudinal rib its. `As the parts are thus formed, when a rock shaft occupies an inactive position, its groove la? overlies the rear ends of the escapement levers and permits the latter to be rocked freely in opposite directions to effect the release of the matrices (see Fig. 10). When, however, the shaft is in active position, its rib or solid portion 7a3 overlies and engages the upper edges of the Overhanging lips Cb of the escapement levers and thus locks the latter against movement. This form and arrangement of the escapements and the rock shafts is such that the latter may be moved to active position even if' one or more of the escapements should be held in abnormal position, as so illustrated in connection with the upper magazine in Fig. 10. In such event (see particularly Fig. 11) the rib 71,3 of the rock shaft enters the recess Ca of the abnormally located escapement, and passes over the overhanging lips Cb on the remaining escapement levers, holding the latter down against the action of their springs C4. In this way the caught escapement lever, instead of locking the rock shaft against rotation, as before, permits its free rotation at all times.

The invention, therefore, consists broadly in the provision of locking means which will insure the locking of the escapements of all the magazines when the front plate is swung forwardly, and the mechanisms illustrated are alike in the respect that each series of escapements is provided with a locking device so formed or arranged relatively thereto that it can be moved to active position even when one of the escapements is improperly located. In the iirst two forms, this result is secured by the provision of a supplemental locking device which coperates indirectly with the escapements, that is, through the medium of the pivoted actuating levers C1, the latter being suitably formed so as to permit the locking device to be moved to its active position even though one of the escapements be caught; and in the last form, therock shaft H and the escapements with which it directly cooperates are modified, orchanged from their ordinary construction, so as to permit the shaft to be rotated to active position when one of the escapements is caught. The last form also presents the additional capability of insuring the proper locking of the escapements in changing back and forth between the two magazines, it being noted that the liability of the escapements becoming caught by improperly located matrices ispresent during this operation as it is when the front plate is swung forwardly.

It is well known that in some machines of the class illustrated, the magazines may be 130 provided with locking devices to engage directly with the contained matrices to hold them therein, instead of engaging with the escapements as shown. In both cases, the matrices are locked within the magazines, in the first directly, and the second indirectly. It will be apparent, therefore,that my invention comprehends both arrangements, it being the essential idea to insure the locking of the matrices within the magazines before the escapements and their actuating members are disconnected. However, the use of the locking devices to hold the escapements against operation is preferable, possessing certain advantages which would not obtain when they are arranged to cooperate directly with the matrices.

As is also well known, the locking devices may be variously modified in form or applied to many different classes of machines. It is to be understood, therefore, that my invention has been shown merely in preferred form and by way of example and as applied toaparticular style of machine, and obviously many modifications and alterations therein and in its mode of application will suggest themselves to those skilled in the art without departure from its scope.
