Application October 12, 1936, Serial No. 105,307 4 Claims. (Cl. 199-53) The present invention relates to a 'guard for mold disc ll is mounted on a shaft I2 and is use on Linotype machines ’for preventing the provided with Water compartments, not shown, spattering of molten metal during the casting of for cooling purposes. 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 ele vator for supporting the same and carrying said line to the casting part of‘the’machine. The casting is accomplished thru the use of a pot containing molten metal, and in the casting op eration the molten metal is squìrted thru a re stricted 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 justi fied, when the metal is too hot or too cold, when ' The elevator mechanism for holding the mat rices during the casting operation and for trans CFI porting to and from the casting operation is indi cated generally by the numeral I3, and comprises a longitudinal frame I4 and channeled rails I5. The channeled’rails I5 support the matrices I6 and space band I'I as clearly illustrated in Fig. l0. 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 same time permit access to the mold and eleva I9 is attached to a portion of the machine 20 known as the ñrst elevator stop, at which point the line of type is transferred to the distribut ing or second elevator, not shown. 'I‘he 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 ma chine. By referring to Fig. 3 0f the drawing it will be noted that the guard is formed of a chan nel-shaped frame 24 that is substantially rec tangularshaped. A shatter-proof glass 25 is supported Within the frame on the front, top, and two sides thereof, it being understood that 30 the back portion contacting the machine is open tor mechanism should the occasion arise. The invention will be fully and comprehensively the side toward the operator there is provided understood from a consideration of the follow 35 ing detailed description when read in connection be necessary for the operator to have access to 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 25 machine and so positioned that the operator of the machine will be protected from the spatter ing molten metal during the casting operation. A further object of the invention is the pro vision of a guard means for yprotecting the op 30 erator from spattering molten metal and at the 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 illus trating the casting elevator with the guard in position; and Fig. 3 is a perspective view of the guard de 45 tached 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 50 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 55 mold disc II which supports the mold 8. The as well as the end. a hinged door 26. On one side and preferably For various reasons it may the casting mold and surrounding parts and» it is for this purpose that the door 26 is provided. 5 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 45 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 CIK 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 2 2,130,308 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 conñned to the exact showing of the drawing 10 nor to the precise construction described and, therefore, such changes and modifications may be made therein to fit different models of type casting machines as do not affect the spirit oil the invention nor exceed the scope thereof as 15 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 afn’ormally20 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'.
