23 Claims.

This invention relates to linecasting and composing machines and particularly to the shifting of the magazines of multi-magazine composing -machines by an automatically controlled unit responsive to prearranged signals.

For convenience in describing the present invention, the standard structure of a well-known commercial linecasting and composing machine,

1 as illustrated in the accompanying drawing, will be referred to hereinafter as the principal machine, while the mechanism which is operative for initiating the magazine shifting function of the principal machine will be referred to here- -inafter as the control unit.

An object of the invention is to provide control means responsive to selectable elements under the control of stored signals for the magazine shifting mechanism of standard linecasting machines.

The invention features an arrangement for rendering the control unit non-responsive to repeated identical magazine shift signals.

In multiple magazine linecasting machines any one of the two or more matrix storage magazines may be rendered capable of delivering matrices by establishing operative relation between the magazine and a set of matrix selecting lever systems. Such establishment of relationship may be described as qualifying the magazine for operation, since there is conferred upon the magazine a quality which enables it to perform the function for which it is provided, namely, to discharge matrices.

Briefly, the invention includes mechanical means for depressing the magazine shift key of a standard commercial linecasting and composing machine and thereby automatically starting into operation a. magazine shifting mechanism of the linecasting machine. When the magazine shift operation has been substantially completed, the shift key is permitted to return to its unoperated position and the control unit is rendered unable to respond to a like magazine shift signal. A different magazine shift signal will then be effective upon the control unit to effect the depression of the magazine shift key to operate the magazine shifting mechanism whereby the magazines are restored to their previous operative condition. Thus successive different shift signals will alternatively condition the magazines, but successive identical magazine shift signals will not operate the magazine shifting key.

For a complete understanding of the invention, reference may be had tothe following description and to the accompanying drawing in which the single figure represents schematically in perspective a control unit having embodied therein the subject matter of the invention as applied to the magazine shifting mechanism of a standard commercial linecasting machine.

In the drawing, only so much of the mechanism of the principal machine has been shown as isdeemed necessary to disclose clearly the cooperation of the control unit therewith. For a full and complete understanding of one form of 1 selecting means which may be employed for initiating the operation of the control unit which forms the subject matter of this invention, reference may be had to Patent No. 2,036,282, granted April 7, 1936 to E. S. Larson.

Principal machine Referring now to the drawing, the reference numeral l0 designates a pair of matrix storage magazines of a standard commercial linecasting and composing machine. The magazines may be supported at the rear edges thereof by pivots (not shown) and the upper magazine may be supported above the lower magazine in the usual way so that the two magazines may be shifted as a unit. A bracket H, having a downwardly extending arm 12, is provided for supporting the magazines adjacent the front edges thereof and at the lower end of the arm I2 is secured a transversely extending pivot pin l3. A toggle lever system consisting of the levers I 4 and I6 connects the bracket H to a portion I! of the stationary frame of the linecasting machine, there being a pivot pin I8 secured to the frame portion I! for pivotally securing the lower end of the lever 16. The upper end of the lever l4 pivotally engages the pivot pin l3, and the adjacent ends of the levers I4 and I5 are pivotally connected together by the common pivot 19 which has an extension slidable in a slot 2! in the frame portion I! for guiding and limiting the movement of the toggle lever system,

A bell crank lever 22, which is pivotally mounted on a fixed pivot 23, has one end operatively engaging the pivot pin Hi to operate the toggle 5 lever system and has its other end connected by a link 24 to a crank pin (not shown) carried by a rotatable cam member 26. The rotatable member 25 is fixed to a rotatable shaft 21 which is driven through the medium of bevel gears 28 and 29, shaft 3|, and friction clutch 32, from a worm gear 33 to which rotation may be imparted by a worm 34. The worm 34 is loosely mounted on a shaft 36, which may be any power driven shaft of the principal machine such as the socalled intermediate shaft. The loose mounting of the worm 3% permits the shaft 36 to rotate independently of the worm, and the shaft has secured thereto in spaced relation to the worm 3d a bevel gear 31.

A clutch sleeve 38 is loosely and slidably mounted on the shaft 35 intermediate the worm 34 and the gear 37 and the sleeve 38 has positive driving connection with the worm 34 through the medium of leftwardly extending fingers 39, which are disposed within slots 4| in the hub of the worm 54. At its opposite end, the sleeve 38 is provided with teeth 42 which may be brought into engagement with recesses 43 formed in the hub of beveled gear 31 to permit the establishment of driving connection between the beveled gear 3? and the worm 34 when the clutch sleeve 33 is shifted rightwardly. The sides of the teeth 52 are preferably disposed obliquely with respect to the faces thereof and the recesses :13 are correspondingly formed, as shown in the drawing, so

that when the clutch sleeve is brought into en-,

gagement with the hub of the rotating bevelled gear 37, a mutual camming action between the teeth 42 vand recesses 43 creates a continuing tendency for the clutch sleeve to be forced out push rod 52 by means of the pivot pin 55.

of engagement. Thus the clutch always seeks disengagement unless restrained therefrom, and means, presently to be described, is provided for so restraining the clutch during intervals in which its continued engagement is desired.

A clutch yoke 44 engages the clutch sleeve 38 and isconnected toa lever 45 mounted on a rock shaft 4? by means of a pin 48. At the opposite end of the rock shaft 41 from the lever 45 there is secured a lever 49 which has pivotally depending from the outer end thereof a link 5!. A push rod 52 is positioned below and in alignment with the link 5|, .and a keylever 53 which is pivotally supported at 54 pivotally engages the The keylever 53 is provided with a finger key 55.

In order to insure the completion of a magazine shift after it has been initiated, the rotatable cam member 25 which operates the link 24 is provided on its opposite face with diametrically opposed recesses 51. A lever 58, pivotally mounted at 55, has one end thereof engaging the clutch yoke 35 and the other end terminating in a portion 5! which may enter a recess 51.

The operation of the disclosed part of the principal machine is as follows: When the magazines are to be shifted, the finger key 55 is de pressed, which causes the keylever 53 to rock on the pivot 55 and raise the push rod 52 upwardly. The push rod 52 reciprocates the link 5!, thus rotating the lever 49 and rocking the shaft 47 to cause the teeth 42 on the clutch sleeve 38 to engage the hub of the continuously rotated beveled gear 3?, and thus drive the worm 3 5,

The rotation of the latter causes the worm gear 33 to be driven and through the medium of elements previously described the member 26 is rotated and the link 25 is thereby caused to rotate the bell crank lever 22. The bell crank lever 22 may be rotated counterclockwise from the posltion shown in the drawing and this causes the pivot pin Hi to travel to the opposite end of the guide slot 2i and rotates the lever l6 counterclockwise onits pivot pin 18 to lower the magazines 55 by drawing downwardly on the lever It.

Since the lever 58 is connected to the clutch yoke l i, the shifting of the clutch yoke to cause engagement of the clutch results in a counter clockwise rotation of the lever 58 about the pivot 59. This rotation of the lever 58 causes the portion Bl of the lever to be withdrawn from a recess 5| in the face of the rotatable cam 26. As cam 26 rotates, the lever 58 is blocked from clockwise rotation by the engagement of the portion 5i of the lever with the face of cam 26. When cam 26 has completed one-half revolution, which occurs at the completion of a magazine shift, a recess 51 is brought into alignment with the portion 6! of the lever 58, so that that portion may enter the recess, thus permitting the clutch to become disengaged by a leftward movement of the clutch sleeve 38 under the influence of the mutual camming action of the teeth 42 and recesses 53. a

Control unit The reference numeral 52 designates a set of code bars which are adapted to selectively condition the code levers 63 and 64. The code bars are responsive to stored signals in a manner fully described in the above identified patent, and a complete understanding of the manner in which the selective conditioning of the selectable codelevers 53 and 65 is accomplished may be ob-' It is deemed tained by reference to the patent. sufficient to state here that the code bars 62 are capable of a slight endwise reciprocatory motion' and that the selective conditioning of the code levers 83 and 6d occurswhen the code bars 52 assume certain predetermined positions.

l vers 53 and 64, it is reciprocated rightwardly by a function performing bail not shown.

Levers 66 and 5'! pivoted at 68 engage the code levers 53 and 54 respectively, so that upon the rightward reciprocation of one of the code levers,

its cooperating lever 66 or 67 is rotated in a clockwise direction. The levers 66 and 6'? are normally urged in a counterclockwise direction by the springs 69 and H3 respectively.

Adjacent to the left-hand end of the levers 66 and 51, a T-shaped member H which has slots 12 in the shank portion thereof is slidably mounted upon the fixed pins 73.

75 of a lever Ti. The lever 71 is fixed to a shaft 18 which may be journalled in any convenient fixed portion of the principal machine and which has secured to its opposite end a lever 19 which: is provided at its forward end with a downwardly extending portion 8|, the lower end of which is disposed in alignment with and preferably a small distance above the finger key 55. Adjacent to the lower end of the lever H is a bell crank lever 82 which constitutes a latch andv The bell crank lever 82.

wise direction, and a spring 88 urges the member H rightwardly, the springs 87 and 88 normally maintaining the end 8| of lever 79 from operative engagement with the finger key 55.

The arms of the T-shaped lever H are provided with slots 91 in which are disposed pins 92 carried by a reciprocable member 93. The member 93 is thus supported by the T-shaped lever H and is provided with rightwardly ex- Upon the selective conditioning of either of the code At the lefthand end of the shank of the member 1| is: mounted a pin l' which is disposed within a slot A spring 86 urges the bell.

tending portions 94 which are spaced apart a distance different from the distance between the left-hand ends of the levers 66 and 61, so that one of the projections 94 may be aligned with the end of one of the levers B6 and 61 in each of the limiting positions of the reciprocable member 92, as determined by the slots 9|. A lever 95 which is pivoted at the fixed point 96, has one end pivotally engaging the reciprocable member 93 at 97 and the other end pivoted at 98 to a link bar 99 which is pivotally associated with the magazines II] to be moved upwardly or downwardly as the magazines are so moved. The link bar 99 is provided with a hump or cam portion 10! and the upper end of the bell crank lever or latch 82 is provided with a cam projection I02 disposed in the path of the cam portion ll of the link bar 99.

The operation of the control unit is as follows: Since the lower portion 94 of the reciprocable member 93 is in alignment with the left-hand end of lever 56, it will be assumed that a predetermined stored signal-has actuated the code bars 92 to condition selectively the code lever 99. The rightward movement of the code lever 33 under the influence of an operating bail (not shown), will cause the lever 66 to be rotated clockwise and its left-hand end will move leftwardly the lower element 94 of the reciprocable member 93 which, by reason of the disposition of the pins 92 in the slots 9|, will cause the T- shaped member H to slide leftwardly upon the pins 13. The pin and slot connection of the member ll with the lever 11 will cause the latter to be rocked clockwise, and as the lower end of the lever ll moves behind the shoulder 84 of the latch 32, the latter will be rocked counterclockwise by its spring 86 to retain the lever 11 in the position into which it has been rotated. The rotation of the lever H causes the shaft 18 to rock in clockwise direction, which carries the end 9! of the lever 79 into engagement with the finger key 55 and causes the depression of the finger key and thus the actuation of the keylever 53. The actuation of the keylever 53 will cause the magazine shifting mechanism of the principal machine to operate in the manner previously described. Since the magazines have been shown in their uppermost position, the operation of the magazine shifting mechanism in response to the selective conditioning of the code lever 69 will cause the magazines to be lowered to their lowermost position.

The downward movement of the magazines causes the link bar 99 to be moved downwardly, and an upward movement is transmitted to the reciprocable member 93 through the agency of the lever 95. As the reciprocable member 93 moves upwardly, the lower projection 94 is moved out of alignment with the lever 66 and the upper projection 94 is moved into alignment with the end of lever 61. It is apparent from this description that should the code lever 63 again be selectively conditioned in response to a re peated signal, the magazine shifting mechanism would not be affected, for the reason that the lower projection 94 of the member 93 would be out of operative alignment with the lever 66. This arrangement prevents the magazine shifting mechanism from responding to repeated identical magazine shifting signals and insures the alternative conditioning of the magazines in response to the proper predetermined signals only.

The restoration of the magazines to the position shown in the drawing, after a shift operation as described in the foregoing paragraphs, is accomplished by causing the code lever 64 to be selectively conditioned in response to a predetermined signal which differs from the signal to which the code lever 63 is responsive. The selective conditioning of the code lever 64 results in a clockwise rotation of the lever 61, which, through the operative alignment of the upper projection 94 therewith, will cause the T- shaped member H to slide upon the pins 13, thus rotating the lever 11, shaft 18 and lever '19 to effect the depression of the keylever 53. The depression of the keylever 53 causes the magazine shifting mechanism of the principal machine to operate in the manner previously described, whereby the cam member 25 is rotated through one-half revolution to rotate the bell crank lever 22 clockwise by means of the link 24 and thus the magazines ID are returned to their uppermost position.

The upward movement of the magazines is accompanied by an upward movement of the link bar 99, and a clockwise movement of the lever 95. The member 93 is moved downwardly upon the clockwise movement of the lever 95, bringing the lower projection 94 into alignment with the lever 96 and withdrawing the upper projection 94 from alignment with the lever 61.

In addition to shifting the reciprocable member 93 as outlined in the preceding paragraph, the downward or upward movement of the link bar 99 causes a clockwise rotation of the latch 82 by reason of the engagement of the cam portion I91 with the portion I02 at the upper end of the latch 82. Upon the clockwise rotation of the latch 82, the lever I? is released from engagement with the shoulder 84 thereof and is enabled to respond to its spring 81 to rotate counterclockwise and thus release the finger key 55. The spring 88 cooperates with the spring 8'! in releasing the lever H, and the springs also cooperate in returning the T-shaped lever H to its normal or inoperated position.

Although a particular embodiment of the invention has been shown in the drawing and described in the specification, it is to be understood that the invention is not limited to the specific structure disclosed, but that it is capable of modification, rearrangement, or substitution of elements and operations without departing from the spirit of the invention and within the scope of the appended claims.
