SAID LIEBERKNE 1 ATENT oF TYPE-CASTING MACHINE.

To (LIZ It'll-0711, it may concern-.-

Be it known that we, ROBERT DRUMMOND and WILLIAM C. LIEBERKNEGHT, citizens of the United States, and residents, respectively, of the borough of Brooklyn and of the borough of Manhattan, both in the city and State of New York, have invented a new and. useful Improvement in Type-Casting Ma chines, of which the following is a specification.

This invention relates to an improvement in type-easting machines, and is particularly directed to means for making low quads and spaces, with the object in view of permitting the use of the type cast by the machine for printing purposes without danger of the quads and spaces coming in contact with the print-ed surface.

A practical embodiment of our invention is represented in the accompanying drawings, in which c Figure 1 is a view in front elevation of a )ortion of a type-casting machine of welllrnown and-approved construction with our device for making low quads and spaces applied thereto. Fig. 2 is a view in side elevation of the same. Fig. 3 is a top plan view with certain of the parts broken away to more clearly show the parts beneath them, the device for making the low spaces being in its closed position. Fig. 4 is a vertical section through the machine in the plane of the blade, showing the device for making the low spaces in its open position. Fig.5 is a top plan view of the same. Fig. 6 is a detail ver tical section in the plane of the blade, show-- ing the parts in the position shown in Fig. 3. Fig. 7 is a detail view showing the type, the en-quad, the em-quad, and the justification space or. blank. auxiliary blade in top plan and face views, and Fig. 9 is a transverse vertical section taken in the plane of the lock for the auxiliary blade.

The main blade {denoted by 1) for determining the width of the body of the type, quad, or space is operated in the well-known manner by the sliding bars 2 and. 3.

The blade 1 is surmountedby an auxiliary blade 4, which is permitted a slight longitudinal sliding movement thereon at predetermined intervals for opening and closing the top of the mold.

Specification of Letters Patent. Application filed October 31,1903. Serial N0. 179.290.

of its rearward movement'with Fig. 8 shows the lock for the Patented March 26, 19 57 The forward end 5 of the auxiliary, 4 overlaps the forward end ti of the main blade a short distance below the face of the mov-' able matrix-case 7 so that when the auxiliary blade is moved to closethe top of the mold the metal within the mold will be stopped a corresponding space from the face of the matiix-ease to form a low quad or space. i v

When the auxiliary blade 4 is at the limit respect to the blade 1, the face of its for "d end 5 will be in alinement with the face 01 the forward end 6 of the main. blade, thus permitting the metal within the mold to flow into engagement with the type on the face of the movable matrix-case 7. v i i The mechanism which We employ for operating the auxiliary blade at predetermined intervals independent of the operation of the main blade to form low quads and spaces for the diilerent spacesviz., the err-quad; the em-quad, or the justificati0n-space-is as follows: The auxiliaryblade 4 is provided with a recess 8. A earn 9, carried by the bar 10, fitted to slide in a suitable bearing 11, is arranged in position to enter the recess 8 at-pr'edetermined intervals for sliding the auxiliary blade forward independently of the main blade 1.

The cam-bar 10 is connected at 12 to one arm 13 of a two-armed lever pivoted at 14 to swing horizontally, the other arm 15 of the said lever having a pin-and-slot connection 1.6 17 with an arm 18 of a second two-armed lever pivoted at 19* to swing horizontally,

the other arm 19 of the last-named two-- 'armed lever carrying a laterally-extended controlling-bar 20. v c A The movable blade 4 is provided withra recess 21, which is engaged and disengaged: by

a laterally-sliding lock 22,-carried by the main blade 1.. The movement of this look 22 is controlled by the movement of the rocking lever 13 15, as follows: -A laterallysliding bar 23 has its outer end provided with a pin-and-slot connection 24 25 with the arm 13 of the rocking lever 13 15. The inner end of this laterally-sliding bar 23 is provided with two upwardly-extended arms 26 27 which engage the outer faces of therearwardly-ex'tended arms 28 29, of the lock 22, This connection between the lock and the 25 18- 19 and 13 1-5 fitted to slide into and out of the recess 21 in the under side of the movable blade 4, and a depressed portion 22**, adjacent to the lip 22 on or'over which depressed portion the bla e 4 may freely move 1n a longitudinal dio rection when the lock 22 is moved laterally r 5 which is 20 20 of the rocking lever 18 19.

to diseng e the ii 22* from the recess 21. The mec anism or operating the movable blade 4 to form the uads or the justification-spaces is as fol ows: The wedge 30, operated and which controls the movement of the main blade 1 in the usual manner'to form the pro er mold-slot for the 'ustification-space, IS a so provided with a iug 31, which embraces the controlling-bar As the wedge is moved inwardly laterally with respect to the mold-blades the lug 31 will engage the yielding stop 32, and as the wedge com letes its inward movement the two rocking evers will be rocked in adirection to slide the cam 9 into the recess in the movable biade 4 for sliding the blade into position i to close the top of the mold-slot at a distance from the type on the face of the matrix-case.

Before the earn 9 is moved a suflicient distance to slide the movable blade 4 forward the lock 22 is withdrawn from the recess 21 the movable blade through the controllingbar 23. P

It is to be understood that the blade 1 is operated in the usual manner by the sliding bars 2 and 3 to first bring it into position to form the space of the required thickness and is then moved toward the mold-slot for forc- 0 ing the space after ithas been formed out of "the mold-slot. This last forward movement of the blade 1 will bring the lock 22 opposite the recess 21 on the movable blade, so that as the ge 30 is moved laterally outward 1 45 it will, through the engagement of the lug 3.1 with the yielding stop 33 on the bar 20, rock the two levers 18 19 and 13 15 back to their normal position and draw the lock 22 into the recess. This same movement will also withdraw the cam 9 from the recess 8 of the movable blade. thus permitting the two blades to be drawn back to their normal pos1- tion by the usual mechanism for withdraw ing the blade 1.

The means which we have shown for sliding the movable blade 4 forward independ- I ently of theblade 1 to form a low quad of a different thickness than the justificationspace-as, for instance, the em-quad-is as 60 follows: The rocking lever 13 15 18 provided witlr'a laterally-extended controlling-rod. 34. The lever-arm 35 engages a ielding stop 36 on the rod 34, which lever is inged'to swing vertically on a pivot 37., carried by a Support 38 of the machine. The upper arm 39 of this lever is connected through a rod 40 with theupper arm 41 of a two-armed. rocking lever 41 42, pivoted at 43 toanother support 44 on the machine. The lower arm 42 of the two-armed rocking lever 41 42 is located in position to be engaged by the matrix case 7 when the matrirecasc' required point by the controlling mechanism for causing the em-quad to be formed. The engagement of the m'atrix-case 7 with the said arm 42 will, through the connections above described, cause the horizontal roclring levers 13 15 and 18 19 to be rocked into position to unlock the. movable blade 4 and slide it forward to close the upper end of the mold-slot as hereinbefore described. This movement will also compress the spring of the yielding stop 33 against the lug 31 of the has been moved to the wedge 30 because of the rocking movement of the lever 18 19, so that when the case '7 is withdrawn from its engagement with the arm 42 the parts willbe returned to their normal position bythe extension oi the spring-yielding stop 33 whcn it is permittedto exert its force. v

The means which we have shown for sliding the movable blade 4 forward independently of the blade 1 to form a low space of still another thicknessas, for instance, for forming an en-quad-1s as iollows: A twoarmed lever has its lower arm 45 fixed to a rock-shaft 46, carried by a bracket 47, cured to the support 38, which arm 45 is err-- tended down into position to be engaged by the matrix-case 7 when the matriiecase is moved to a predetermined point by the controlling mechanism for permitting the en quad to be formed. The upper arm of this lever is also fixed to the shaft 46 and is connected by a rod 49 with one arm 50 ofan r angle-lever pivoted at 51 to a bracket carried by the support 38, the other arm 53 of the said angle-lever having a pin-and-slot connection 54 55 with the connectingaod 4G, hereinbefore described.

The rocking levers 13 15 and 18 19, and thereby the lock 22 and earn 9, are operated through. the rocking lever 35 39 and rod 3-4 in a manner similar to that described with retercnce to the means for controlling the male ing of the em-quad.

By the mechanism herein described we are enabled to form quads and. spaces the faces.

of which will be spaced a considerable distance from the faces of the type without interfering with the operation of the ma chine in any particular.

It is evident that mechanism other than that herein shown and described might be employed for operating the movable blade for forming the low quads and spaces. Hence we do not wish to limit ourselves strictly to the structure herein set forth; but

-- blades to form a low What'we claim is' I 1.
