LINOTYPE SQUIRT GUARD Filed 001;. l2, 1956 FI .Z Ff MZy Patented Sept. 13, 1938 UNITED; STAT-Es PATENT OFFICE 4 Claims.

The present invention relates to a 'guard for use on Linotype machines for preventing the spattering of molten metal during the casting of a blank or typographed slug. Y

As is well knownl in the art after the matrice are set in a line, the line is carried to an elevator for supporting the same and carrying said line to the casting part ofthemachine. The casting is accomplished thru the use of a pot containing molten metal, and in the casting operation the molten metal is squrted thru a restricted opening into the mold. The squirting of the metal presents a hazard to the operator of the machine since it frequently occurs that the metal will spatter, which is caused primarily when the matrices are loosely held or when they become worn, when the line is improperly justified, when the metal is too hot or too cold, when small fragments of metal adhere to a matrice 2() or space band, when space bands slip off the jaws which causes an opening therebetween, or when a proper lockup is not obtained.

The primary object of the invention therefore is to provide a guard connected to a Linotype machine and so positioned that the operator of the machine will be protected from the spattering molten metal during the casting operation.

A further object of the invention is the provision of a guard means for yprotecting the operator from spattering molten metal and at the same time permit access to the mold and elevator mechanism should the occasion arise.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing.

Fig. 1 is a side elevation, partly in section, of a Lintoype machine in position for casting a type slug, the guard being shown in protective posi- 40 tion.

Fig. 2 is a front elevational View and illustrating the casting elevator with the guard in position; and

Fig. 3 is a perspective view of the guard detached from the machine.

Referring to the drawing for a more detailed description thereof, the Linotype machine herein illustrated consists, briefly, of a pot 5 containing molten metal, and having a spout 6 thru which the molten metal is ejected into the slot 'l of the mold B. The pot 5 is supported on the main frame 9 and adapted to pivot thereon thru the arm IE), the pivotal connection not shown.

Intermediate the pot 5 vand the frame 9 is the mold disc II which supports the mold 8. The

mold disc ll is mounted on a shaft I2 and is provided with Water compartments, not shown, for cooling purposes.

The elevator mechanism for holding the matrices during the casting operation and for transporting to and from the casting operation is indicated generally by the numeral I3, and comprises a longitudinal frame I4 and channeled rails I5. The channeledrails I5 support the matrices I6 and space band I'I as clearly illustrated in Fig. l of the drawing. The justification mechanism is indicated generally by the numeral I8. The elements above described comprise a portion of the usual Linotype machine with which the guard is associated.

The guard indicated generally by the numeral I9 is attached to a portion of the machine 20 known as the rst elevator stop, at which point the line of type is transferred to the distributing or second elevator, not shown. 'Ihe guard I9 is attached thru the bracket 2| being secured thru bolts or the like 22, said bracket being pivotally connected at 23 to permit the guard to swing into and out of engagement with the machine. By referring to Fig. 3 0f the drawing it will be noted that the guard is formed of a channel-shaped frame 24 that is substantially rectangularshaped. A shatter-proof glass 25 is supported Within the frame on the front, top, and two sides thereof, it being understood that the back portion contacting the machine is open as well as the end. On one side and preferably the side toward the operator there is provided a hinged door 26. For various reasons it may be necessary for the operator to have access to the casting mold and surrounding parts and it is for this purpose that the door 26 is provided. It will also be noted that the lower end of the door is L-shaped as indicated at 2'I thru which extends the adjusting mechanism, not shown, for varying the measurements of the line to be set. The L-shaped portion 2l permits the positioning of the adjusting mechanism and .at the same time allows for the guard to completely surround the mold and casting parts to protect the operator from spattering metal. The bracket 2| is also provided with vertical slots 28 thru which the bolts or the like 22 pass for attachment of the guard to the machine, and by means of said slots the guard can be adjusted toward and away from the channel rail l5, being adapted to move a limited distance within said slots.

From the above description it will be apparent that there is provided a new and novel type of guard which protects the operator of a Linotype CFI CIK

machine from the spattering of molten metal during the casting of a blank or typographed slug. The provision of the guard does not in any manner interfere with the normal operation of the machine since all parts are visible and readily accessible.

It is to be understood that this improvement is capable of extended application and is not conned to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein to fit different models of typecasting machines as do not affect the spirit oil the invention nor exceed the scope thereof as expressed in the appended claims.

What is claimed as new is:

1. The combination with a machine for casting type bars, comprising a holder for type matrices,

a mold cooperating therewith, and means for forcing molten metal into a mold, of afnormally relatively stationary shield-pivotally connected to the machine fory covering the matrices and mold, said shield being substantially rectangular shaped and provided with transparent top, side and fron-t walls.

`2'. The combinationl with a machine for cast.-

ing type bars, comprising a holder for. type matrices, said holder forming part of an elevator mechanism, arnold cooperating with said holder, and7 means for lforcing molten metal intoV said mold, of ay normally relatively stationary shield pi-votally connected to the upper end of the machine forcovering the matrices and mold during theY casting operation, said shield being substantially rectangular shaped and provided with transparent top, side and front Walls, and means carried by said shield for permitting access to the casting mold.

3. The combination with a machine for casting type bars, comprising a. holder for type matrices, said holder forming part of an elevator mechanism, a mold cooperating with said holder, and means for forcing molten metal into said mold, of a normally relatively stationary shield pivotally connected tothe upper end of the machine for covering the matrices and mold during the casting operation, said shield being substantially rectangular shaped and provided with transparent top,v .side and front Walls, and a door hingedly connected to said shield for permitting access to the mold and elevator mechanism.

4.
