Be it known that I, H NRY'A. WrsirWoon,

S a resi ng t- New York, the county of New York and State of New York, have invented anew and of which Whitizen fot the United useful Stereotype-Casting Device, the following isia specificationi Up to within recent years,

stereotypes has been the delay occasioned with the rapidity of printing in modern frame which constitutesja part thereof.' Fig; plants; 'In order to overcome-this difiiculty, 3 is a side elevation of ap'ortion of the device have heretofore invented several machines on an enlarged'scale showing how t e plate is for-the rapidproduction of-s'tereot e printdelivered. Fig'. 4'is a Ian-of the casting-box plates but most of these have een suit proper, when in'closed position. Fig.- 5-is. a. ab eforusechieflyin lar e plants. Some atfront yiew of the same, and Fig. 6v is a sectempts' have beenmade a tively simple wayso ing the use such devices ing box from and to remove to a pos tion in taken from the castingbox.

The principal objects of the present invention are to provide means wherebythe two parts of the casting box may be separated in y a rocking motion without having any change in the character of motion of the partwhich carries being positively guided), the use of complicated machinery suitable only for large plants, and at the same time, to provide means whereby automatically separated from the casting box and delivered, preferably by gravity, in a convenient and sim le manner into a position where it will be rea' 11y accessible and from which it may be removed at leisure; also to provide an efficient guiding devicefor the movable member of the box, a

a convenient and simple manner the plate (said part without involving the plate may be the casting of done in manually oper ated casting boxes which 'are'necessanly manipulated at a very slow speed as compared with other printing'op rations and in fact,

is usually. called vthedrag;

is constructed 111 any .85 being operated in the 1 7 by links 18 with the fornl of matrixmanipulating mechan sm, which is'not shown herein. as

within the scope oi-this invention in any dostub?understood that the motion of the drag aft-er the plate is cast is'forthe purpose of separating the same from the cast plate which is left on the core orc'ope. "Consequently, this motion is of comparatively small extent, it being necessary merely to remove the drag far enough to permit manipulation of the core in a manner which will be described.

hereinafter. After the plate is cast and the drag moved back, as is indicated iirdotted lines in Fig. 1, .the other mold member-or core .60 is rocked directlv forward, having a rocking motion from t e start in order to deliver the cast plate. By reason of giving the back a moto the frame or base 10 in the present instance, by a latch 21 pivoted on a fulcrum stud 22 at the front of the core. This latch swings in. a substantially vertical plane and upon them in either direction.

engages a pair of studs 23 mounted on the frame on o posite sides. of the front of the core. The atch is provided with a handle 24 for manipulating it. When the lat-ch is swung to unlock the core from the frame, it will be seen that the handle will serve not only for this function, but for rocking the core over to the-front and that a simple swin 'ng motion of the latch by pulling the han e upwardly, issufiicient to accomplish both functions.

- When the core is unlocked and swung to the front, it rocks on a pair of rockers 25 to which it is secured and which roll on tracks 26 formed onthe frame or base. In order to cause the core to rock without sliding either forward or back along the tracks so thatit may register with the back and with the delivery frame, as will be described, the rockers are provided with guides 27 which'are engaged by rolls 28 on the frame. These guides are connected with the rockers in such a manner, and they are of such -shape,-that the'rockers will be constrained to roll along thetracks and will be prevented from sliding For this reason, the shape of the guides 27 is substantially that of the 'cycloidal curve. I As will be obvious, this form of guide serves to hold the rocker in'proper p osition'and to return the core to the same place after each operation.

The guides and the rockers are of sufficient length to permit the core to rock over to a position beyond the horizontal so that when the core comes to rest, it is sufficiently inclined with its jet end down to permit the plate to be discharged by gravity. Consequently, if. the casting position of the core is vertical, the. effective rocking surface of the desired.

nary or desired manner.

and the guide end segment of the casting box. This scgment constitutes the bottom of the mold when the parts are in casting position, as is indicated in Fig. 6, and it is provided with springs37 secured to the coreand on thcsegment itself to hold it yield ingly in proper position for forming the end of. the cast plate. When the stop 31 is engaged by the arm 30 and the bell-crank 34 swung to the right, the

segment is forced outwardly from the 'cast plate so as to permit theplate to be removed rom the core. At the salne time anarm 40" connected with the arm 30 operates a link 41.

which swings two or more arms 42 upwardly 0 into such position that anti-friction rolls 43 which they carry engage the edges of the plate and eject the same by lifting it to the position indicated in Fig. 3. As has been described, the core at this-time is on an incline and as the rollers are now located in an inclined plane, it will be seen that the plate, being sup orted, entirely by the rollers, is free to be dialivered by gravity and that it'will descend on a series of rollers .44 mounted on a stop 46. The plate, therefore, is automatically deliveredv on the delivery frame and is left in. a position from which itcan be removed while the core is being returned to the back for the production of another plate, if

7 When the core is swung back, a roll 47 on a lever 48 connected with the link 41 engages a stationary cam 49 and returns the link and rollers -to proper position out-of the way of the plate so that the casting may be produced in the usual way. casting box which forms theedges of the plate which aredestined to rest on the rollers 43, which constitutes a part of the matrix carrying mechanism, is not shown herein in detail as it can be'constructed in any ordi- Such, for instance, as that shown in the above mentioned copending application.

The side of the l It is to be observed that the drag is located in position against the core by the toggle lever and that the core is locked to the frame by the latch which has been described. Consequently, the drag can be-mov'ed back out of en agement with the cast plate without un-' I loc ing the core and whenthis has been accomplished, the core can be unlocked and rocked forward with practicallya single mo- 100 the delivery frame 45 which is provided with i tion of the plate. At the end of the traverse and the casting from the core, but delivers the casting into an accessible position where it can be handled in any suitable waywithout further delaying the subsequent operatilo'n of the casting box to produce another p ate. I

, It will be obvious, therefore, that'a device constructed in accordance with this invention, is of a simple and inexpensive character so that it may be used in small plants and that it avoids the complication of a compound movement of a movable member of the casting box, permitting'the two parts. to

'move independently and roviding for exact registration of the parts with each other pon their return motion; also providing to looking the rocking element of the box in a predetermined position, independently of the location of the otherpart of the casting box at that time. a 0
