INTERMITTENT CLUTCH DEVICE FOR TYPE-CASTING AND TYPE-COMPOSlNG MACHINES.

SPECIFICATION forming' part of Letters Patent No. 787,138, dated April 1l, 1905.

Application filed May 9, 1903. Serial No. 156,450.

To /I'm/l/ 1'/ llmj/ con/cern:

Be it known that l, aumen lVnumaN, engineer, a citizen of the hepublic of France,

resnhng at it lvue de la liictou'e, the Republic of France, have invented certain i l l l l i Paris, in i the justilicationwthat is to say, instead of making' lifty-three complete movements it will only make two.

The mechanical arrangements of this invention are shown in the accompanying' drawnew and useful Improvements in intermittent Clutch Devices for '.lype-Casting and 'l`ypeside elevation, respectively, of the new ar- Composing Machines, of which the following isa specilication.

This invention relates to machines for casting and composing' movable type of the system made known by the English latent No. 18,542 of lilou; and it has for its pul'pose to insure a longer duration of and greater security for theI operation of the apparatus for justifying' the lines described in the said patents, and that by means of a simplitication of the movements of the said apparatus.

lleretofore all the mechanisms contemplated for preparing the striking of the molddrawer in view ot' the justification of the line remained continuously in motion, althoug'h they were only used during two revolutions of the shaft before the beginning of each line. The continuously-rocking movements of the yoke 12(7) of the said machines, which follow each other in rapid succession, on account of the great speed of rotation led to such rapid and heavy wear and tear at the piv(')ting-points that the very strictly limited accuracy of the said movements was soon lost and the device for justifying no longer served its purpose. 'lhe present arrangement does away with this objection in that it allows of the rocking movements of yoke 12C being produced exclusively during' the period o'f preparation for the justification before the beginning of each line and of keeping' the yoke 126 at rest during the remainder of the time. 'lrhe advantage of this arrangement is of very great importance even with short lines. For instance,

ings, in which- Figures l and L) are a front elevation and a rangement. Fig'. 3 is a horizontal section ou the line A B of Fig. 2. Fig. L is a plan view of the same parts in a different position.

'lhe cam-disk lll) is indepcudentof the main shaft of the machine 10S) and rotatably mounted on a hanger or sleeve 8, on which it is held by a nut Q. lhe said disk is provided with a lateral crown 3, provided in its turn with a notch 9. lt also carries a pawl l0, mounted on a pivot 1l and subjected to the pull of a l i i l i with lines containing' fifty characters the yoke l'l' instead of remaining m motion, as in the previous arrangement made known by the; aforesaid patents, during the casting of the type and then during the iustitication and the .'arriag'e of the line will only operate during spring' IO".

ln thc position of rest of the cam-disk ll() (see Figs. l to 3) a stop-bolt 5 is engaged in the notch 9 and serves also at the same time as a point of support for the pawl l0. 'l`he said stop-bolt is rotatably mounted on the stud T and connected with a pull-rod 6, by means of which it can be moved away from the notch 9 and out of reach of the pawl l0.

The pull-rod o is pivoted to a lever 20, held in position by the action of the spring' 19, which holds the heel of the lever against an abutting screw 2l. ',lo the lever Q0 is also pivoted the pullrod l2, so that the rod 6 follows the movements o'f the said rod l2, intermittently made at the beginning of each line, as shown by the aforesaid patents.

In front of the pawl l rotates a clutch-disk I, keyed on the shaft of the machine and provided with a single notch 22. (See Fig. l.)

\\"hen the rod l2 is putin motion by the action of a determined combination of perforations of the registering-band, as shown by the aforesaid patents, the stop-bolt is withdrawn from the notch t) of the crown 3 of the disk 1l() (see Fig. i) and at the same time carried out of reach of the pawl through the medium of the lever 2l) and the rod (3. The pawl l0 is thus rendered free to follow the pull of the spring 10 and falls onto the rim of the disk 4, which is revolving. Then When toward the end of this rotary movement of the disk the notch 22 of the latter comes under the pawl 10 the latter falls into the same, and the cam-disk 110 is thus caused to follow the rotary movement of the shaft 109. The parallel form of the striking edges of the notch 22 and of the corresponding meshing tooth of the pawl 10 insures a forward rotation of the cam-disk Which is absolutely invariable With respect to the rotary movement of the shaft.

So long as the rod 12 remains in motion in the manner shown by the aforesaid patents the stop-bolt also remains out of reach of the pawl and out of the notch 9 of the crown 3; but when the rod 12 after the third revolution of the shaft of the casting-machine moves back toward its normal position the lever under the action of the spring 19 also causes the rod 6, together with the stopbolt 5,to move back toward their primary positions. Then the arm 10' of the pawl 10 comes and bears against the stop-bolt 5, and the clutch-disk 4L continuing its movement gradually disengages the said pawl from the notch 22. At the last moment and so soon as the paWl 10 leaves the notch 22 the notch 9 comes opposite thel stop-bolt 5, which then following' the pull of the spring 19 and of the pull-rod 6 falls at once into the said notch 9. The cam-disk 110 is thus brought to rest and the pawl 10 lies out of reach of the clutchdisk 4, so that the latter can continue to turn with the shaft of the machine. At the next line only Will the cam disk 110 be again brought into action, together With the mechanism of justification.

I claim-- 1. In a justifying mechanism for type casting and composing machines, the combination of a shaft, a loosely-mounted disk provided With a notch, a second disk fixedly secured to the shaft and provided with a notch, a springpressed pawl carried by the first Ydisk and adapted to engage the notch of the second disk, a stop-bolt mounted on a fixed support and adapted to engage the notch of the first disk and when in engagement with said notch to support and hold the paw] against the action of its spring, and means for operating the said bolt.

2. In a justifying mechanism for type casting and composing machines, the combination of a shaft, a cam-disk loosely mounted on a support concentric with the shaft, said disk having a lateral ucrown provided with a notch in its periphery, a clutch-disk fixedly secured to the shaft and provided with a notch in its periphery, a pivoted and spring-pressed pawl carried by the cam-disk and adapted to engage the notch of the clutch-disk, said pawl being provided with an arm, a bolt pivoted to a liXed support and adapted to engage the notch of the cam-disk and When in engagement with said notch to engage the arm of the pawl to support and hold the pawl out of engagement with the notch of the clutch-disk, and a lever mechanism for operating the bolt.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
