CASTING-BOX.

SPECIFICATION forming part of Letters Patent No. 709,942, dated September 30, 1902.

Application filed October '7, 1899. Serial No. 732,846. (No model.)

To all whom it )nay concern.-

Be it known that I, EDWIN D. TUCKER, a citizen of the United States, residing at New York city, county of New York, and State of New York, have invented certain new and useful Improvements in Casting-Boxes, fully described and represented in the following specification and the accompanying drawing: forming apart ofthe same.

This invention relates to certain improvelnentsin casting-boxes, and more particularly to the type of boxes which are used in printing-oiices for casting.stereotype-plates.

In'stereotyping casting-boxes as now ordinarily constructed the position of the matrix and the lengthvof the casting are determined by what is ordinarily known as a headgage, this gage being a strip or bar which is located at the inner end of the box and usually pivoted thereto. Inan ordinary curved casting-box the head-gage is provided with handles which are seized by the operators when the box is opened, the head-gagebeing thus turned on its pivot to throw the cast plate forward, so` that it can be readily grasped and removed from the box. The boxes ordinarily used are arranged to stand in vertical position when the molten metal is poured. After the pouring has taken place the box is swu ng into a horizontal position, and the cope or cover is then opened. The operators (for there are usually two) then reach down and rock the head-gage to displace the castA stood, time is of essentialy importance in the i stereotyping operation. In newspaper-offices every eifort is made to shorten the time between the Closing of the forms and the appoarance of the completed paper on the street, the yObject being to delay the closing of the forms as long as possible, so as to get in the late news. In large Oflices, therefore, where a considerable number of plates have to be cast, strenuous effort is made to save time between the closingr of the forms and the starting of the presses, and particularly in the stereotyping operation.

The object of this invention is to produce a casting-box in which the operation of displacing the cast plate in the casting-box may be more quickly and easilyperformed,thereby saving time in the operation of casting.

A further object of the invention is to produce a casting-box in which the cast plate shall be automatically displaced or thrown forward by the movement of the cope or cover in opening the box.

With these and other objects in View the invention consists in certain constructions and in certain parts, improvements, and combinations, as will behereiuafter described and then pointed out in the claims hereunto ap pended.

In the accompanying drawings, which form a part of this specification and in which like characters of reference indicate the same parts, Figure l is a side view ofso much ofa castingbox as is necessary to illustrate one form of the invention.. Fig. 2 is a plan view of the construction shown' in Fig. 1. Fig. 3- is a vert-ical sectional View of the construction shown in Fig. l, the box being shown as partly open and the gage thrown forward to displace the plate. Fig. 4 is a view similar to Fig. 3, but illustrating the operation of the parts as the cope or cover of the box is being `tion', of a sornewhat'different form of box and illustrating another form of the displacing devices. Fig. 9 is a detail sectional View.

In the accompanying drawings, l indicates IOO the body or mold proper, which in the form tal position the projections 10 will strike the of the invention shown is of the ordinary curved or semicircular form and intended for casting curved plates, such as are now universally used on fast rotary presses.

2 indicates the cope or cover of the box, which is preferably pivoted to the body. The construction by which the cover is pivoted to the body may be of any ordinary or desired form. In the construction shown the body is provided with ears 3 and the cover with ears 1. Through these ears runs an ordinary pivot-rod 5, which is secured in position by means of nuts 6.

The body of the box is provided with the usual side gages, which are omitted from the illustration for the sake of clearness, and with a head-gage 7, the purpose of which is to close the inner end of the box and to determine the position of the matrix and the length of the cast plate. The head-gage may be secured to the box in any suitable or desired manner, but is preferably pivoted thereto, as shown, the gage being provided with pins, which are let into short slots 8, located in the body of the box. In the form of the invention shown in Figs. 1 to 4 the Lipper ends 9 of the headgage 7 extend considerably above the body of the box, for a purpose to be hereinafter described. In the ordinary form of box, as has been indicated, the head-gage is moved, after the cast is made and the box is opened, by handles in order to displace the cast plate and throw it forward, so that it may be seized by the operators. These handles must necessarily be short in order not to interfere with the working of the box, and considerable power is required to move the gage and displace the casting, because the short handles afford very little leverage. Furthermore, since the handles are at the bottom of the box the operators have to bend down to reach them. As the bottom of the box when the box is swung into a vertical position is near the door, the handles are not easily reached by the operators, nor are the operators when they have reached the handles in an advantageous position for exercising the necessary power required to start the cast plate. In the present invention means are provided by which the head-gage is operated independently of its handles, which may or may not be omitted. The operating means for the head-gage may be varied very considerably. In the form of the machine shown in Figs. l to 4 the extensions 9, before referred to, lie in the path of projections lO, carried by the cover. These projections are preferably pivoted between ears ll, carried by a bracket 12, bolted to the cover. There is also preferably provided a spring 13, which is secured to one of the ears 1l and bears upon the projections 10, for a purpose to be hereinafter described. In the construction shown in Figs. l to 4 as the cover of the box is raised after the pouring of the metal has taken place and the box has been returned to a horizonends 9 of the head-gage and turn the same on its pivot. The movement of the head-gage causes the cast plate P to be thrown forward, the position of the parts at the time the headgage is at the end of its forward movement being shown in Fig. 3. As the cover of the box is turned still farther on its pivot in order to fully open the box the projections 10 slip over the ends 9 of the head-gage 7. The end of the plate now projects considerably from the forward end of the box, and the plate can be readily seized and removed by the operators. After the plate is removed the headgage is thrown back into position and the cover of the box closed. As the cover is swinging down into its closed position the projections 10 are allowed by the springs 13 to swing on their pivots suiciently to pass the projecting ends 9 of the head-gage, and after they have passed these ends the springs 13 cause the projections to snap back into their normal position.

In the construction shown in Figs. 5, 6, and 7 the operating means for the head-gage are differently arranged. In this form of the construction the cover 2 of the box is provided at its rear end with an angular arm 14. This arm is preferably perforated, so that the pivotrod 5 passes through it. This angular arm has a socket 15 formed in its ends, in which socket is located a projection 16, this projection being in the form of a spring-seated pin, the spring which controls its movement being marked 17. The projection is limited in its movement by means of a pin 19, which works in a slot 2O in the angular arm. In this form of the invention the body of the box has fixed thereto a slotted plate 21, the said plate being arranged just back of the head-gage, as is clearly shown in Figs. 5, 6, and 7. The slotted plate is held in position and the extent of its movement is controlled by means of a headed pin 22, which is fixed to the body of the box. The projection 16 has one of its edges slightly beveled, the beveled edge being marked 16'. In this form of the invention as the cover of the box is raised the projection 16 strikes the slotted plate 21 and throws it forward. The plate in its turn turns the head-gage on its pivot, and thus causes the plate to be thrown forward in the box. The further movement of the cover on its pivot causes the projection 16 to pass the edge of the slotted plate 21. After the cast plate is removed the head-gage is thrown back into position, and as the cover of the box is closed the spring-controlled projection is allowed to slip over the edge of the plate 2l, this movement being facilitated by reason of its lbeveled edge 16.

In the forms of the invention so far described the opening movement of the cover is caused to automatically operate the headgage to move it forward and displace the cast. While the invention will preferably be embodied in constructions by which a move- IIO ment of the cover automatically displaces the cast, it is not necessarily limitedl to such constructions.

In the form of the invention shown in Fig. 8 the head-gage 7 is operated by means of a sliding plate 23, the plate being connected by a pin 2J: and slot 25 to a bell-crank 2o' 27, v

which is mounted between ears 28, carried by the body of the box. The bell-crank 26 27 is operated to throw the plate 23 forward and rock the head-gage by means of a springcontrolled plungerrod 29, said rod being mounted in a bracket 30, which is secured to the frame 3l of the b oX, the construction being such that a downward movement of the plunger rocks the bell-crank and throws the plate 23 inward. of the plunger may be effected in Various ways. Preferably, however, the plunger is secured to atreadle 32, said treadle being piv` oted on a pin 83, mounted in the frame 3l. In this form of the construction it is neces sary that the connection between the arm 27 of the bell-crank and its operating-rod 29 be such as to permit the casting-box to be swung upward on its trunnions in order that the molten metal may be poured into it. This connection may be of various forms. In the construction shown the rod 29 is provided with an inwardly-projecting stud 34, said stud having an open groove 35 therein, which takes over a pin 36, carried on the arm 27 of the bell-crank. As the box swings upward on its pivot, therefore, the pin 36 passes out o f engagement with the groove 35. When, however, the box is swung downward into a horizontal position, as 1shown in Fig. 8, the pin 36 is again engaged by the groove in the stud 35, and the parts are in position so that the bell-crank 26 27 may be operated through the rod 29 and treadle 32. invention while the head-gage is not automatically operated by the movement of the cover it is very quickly and readily operated. The operator after swinging up the cover of the box simply steps on the treadle. He does not, therefore, have to bend forward, as in the old form of box, and, furthermore, the construction affords an easy and powerful means for throwing out the plate.

The construction by which the invention is carried into effect may be widely varied. It is to be understood` therefore, that the invention is notlimited to the precise constructions which have been shown and described.
