Speceation of Letters Patent.

Patented May 3, 1917.

Application filed. July 8, 191.5. Serial No. 38,814.

T0 all whom t may con/Jorn Be it known that we, LEGRAND FRLnL and CLAUDE L. F RIEL, both citizens of the United States, residing at the city of Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Casting Mechanism for Producing Linotype, of which the following is a specification.

In the Mergenthaler linotype machines the mouth of the casting mold is of a size to cast the longest and thickest line used with the machine. When a linotype of less length and thickness than the maximum linotype is to be cast the mouth of the mold must be reduced in size. This is done by putting in liners to reduce the size of the mouth. These liners must be held rigidly in place and it takes considerable time to adjust the mouth of the mold Wherever the size of the linotype is changed.

It is the object of our invention to simplify and reduce the time of making the change.

A. further object is to simplify the method of ejecting the cast linotype.

In the drawings forming a part of this application Figure 1 is a front elevation of the mold and connected parts.

Fig. 2 is an end elevation of the parts shown in Fig. 1, with parts broken away and other parts omitted.

Fig. 3 is a section on the line 3-3 of Fig. 1, with the mouth of the melting pot shown in dotted lines.

Fig. l is a section on the line 4-4 f Fig. 1.

In the drawings 10 is a U-shaped supporting frame which is secured to the floor 11 by bolts or screws 12. The end members of this frame are provided with oppositely disposed supporting lugs 13 which support the movable mold frame 14 and top lugs 15 which engage the top of the mold frame and aid in holding the .mold frame slidably mounted in the supporting frame. The mold frame is provided with the usual Mergenthaler mechanism for reciprocating the mold frame toward and away from the line of matrices when positioned for casting a linotype. rlhis mechanism is not shown as it would obscure the drawings and is no part of our invention. Upon the base bar 16 of the mold frame is slidably mounted a block 17 which has a rack shank 18. A pinion 19 mounted on shaft 2O meshes with rack 18. By rotating shaft 20 block 17 is moved to thc right or left. The central longitudinal portion of the upper face of block 17 is wedge shaped as shown by dotted line 21 in Fig. 1. Resting on the wedge shaped face of block 17 is a coacting wedge 22 which carries a post 23 on its upper face. Post 23 is preferably rectangular in cross section and passes through the central bar 24: of the mold frame and also through a bearing 25 attached to the lower side of bar 24.

Bearing 25 could be omitted. @n the top of post 23 and movable therewith is the base block 26 of the mold. On top of block 26 is a plate 27 which extends beyond the right hand end of block 26 and slopes downwardly to partially support and guide the linotype as hereafter explained. To the right hand end of block 26 is secured an arm 28 which projects rearwardly from block 26 until it is clear from all connected parts and then passes upwardly and then forwardly and terminates in a guide bar 29 which extends over the longitudinal center of block 26 and also projects to the right thereof as best shown in Fig. 1. In the bottom of bar 29 is a dovetail groove 30 in which is slidably mounted the top of the right hand end piece 31 of the mold. End piece 31 has a wing 32 which projects to thel right thereof and when end piece 31 is moved to the left to shorten the length of the linotype this wing acts as a stopper for so much of the mouth of the melting pot as comes into engagement therewith.

Looking at end piece 31 from the left it will be seen that it consists of a broad bottom portion 31a, which in all positions forms the right hand end of the mold, and a central narrower portion or shank 31b which ends in a dove tail head 31C. Shank 31b passes through an aperture 32a in the top member 33 of the mold near the right hand end thereof. Along and forming a portion of the top (of member 33 is a dove tailed ledge 33a which slides in a dove tail groove 34a in the central portion of the top bar 34 of the mold frame which is wider in the central portion than at the ends. Near the right hand end of member 33 and on the lower surface thereof is a small lug 33b which lightens the linotype and aids in ejecting it as hereafter explained. A groove 33 extends along the face of member 33 to receive projections of the matrices. On the left hand end of member 33 is a shank which passes through an aperture 36 in frame 10 and between the furcations 37a of lever 37. The upper end of lever 37 is forked and the forks have transverse elongated apertures 3S therein through which and throughthe end f of shank 35 passes a pin 39. Lever 37 is pivotally connected by pin 40 to a sliding block 41 slidably mounted to move to the right or left in the top of frame 42. Block 41 has a dove tail lug 41a which is received inra dove tail groove 42a in the top of frame 42 as best shown in Fig. 2.

The lower end of lever 37 is provided with a transverse aperture 43 through which and through crank 44 passes a pin 45. Crank 44 is mounted on shaft 44 and is driven by suitable mechanism (not shown). On the bottom of block 41 is a rack 46 which is engaged by a pinion 47 mounted on shaft 48. The left hand end of the casting mold is a plate 49 which is attached to bar 24 and extends to and contacts with member 33. In Figs. 3 and 4 the matrices 50 are shown as positioned for casting, the supporting mechanism being omitted. The melting pot 51 shown in dotted lines is advanced and the casting performed inthe well known'manner of the Mergenthaler linotype machine.

Should it be desirable to change the thickness of the linotype the operator rotates shaft 2O by means of a wheel 52 to bring pointer 53 mounted on shaft 2() to that position on a scale mounted on disk 54 which indicates the desired thickness of the line. The rotation of shaft 2O moves block 17 and through wedge 22 post 23 raises or lowers block 25 thereby making the linotype thicker or thinner depending upon whether block 26 is raised or lowered.. Should the length of the line require change the operator rotates shaft 48 by means of a wheel 55 to bring pointer 56 mounted on shaft 48 to that position on a scale mounted on a disk 57 which indicates the desired length of line. |The rotation of shaft 48 moves block 41 to the right or left. If to the right the line is lengthened. If to the left the line is shortened. This is accomplished by retaining crank 44 stationary in the position shown in Fig. 1 When the movement of block 41 to the left will carry the upper portion of lever 37 to the left. Lever 37 being connected to the upper member of the mold moves this member to the left. The upper member carries with it the right hand end member of the mold thereby shortening the line. As shown in F ig. 1 the mold is positioned to cast the longest 60 line possible so that the first operation would be to shorten the line. After the line is shortened the reverse movement of shaft 48 would lengthen the line.

After the linotype is cast and the matrices removed from the mold shaft 44a is rotated a turn which causes the reciprocation of the upper and righthand end of" the mold, first to the right and then tothe left, the movement to the right carrying the linotype tothe right of the bottom member when it drops of its own weight onto the sloping end of plate 27 and is then removed by the operator. Wheels 52 and 55 are located at the front of the ma- 75 chine conveniently to the operator so that all he has to do to change the thickness of the linotype is to rotate wheel 52 and to change the length of the line he rotates wheel 55, simple and quickly performed so operations.

Having described our invention what we claim is:

1. ln a linotype machine a mold comprising a stationary end member; an adjustable top member; means to adjust the position of the top member; an adjustable end member partly carried by said top member and adjusted as to its position longitudinally by said top member; and a bottom member adjustable vertically; and means to adjust said bottom member.

' 2. In a linotype machine a mold comprising a movable top plate having a lug projecting from its lower face; a stationary endk plate across which said top plate can move; a bottom plate; means to adjust said bottom plate vertically; an end plate carried by said bottom plate and connected to said top plate; means to adjust said last end plate and top plate; and other means to cause the movement of the top plate to eject a linotype.

In witness that we claim the foregoing we have hereunto subscribed our names this 29th day of June, 1915.
