' To all whom it may concern:

rial No. 537,700, filed Jan. 12, 1910, patented- December 14:, 1915", No. 1,164,607.

This invention relates to a machineifor casting stereotype printing plates. While some of the features thereof are capable of use generally for that class of machines, yet the invention is illustrated in a form in which it is particularly applicable to the casting of flat plates.

Among the objects of the invention are to provide a new machine adapted automatically to take one matrix at a time from a pile of matrices in a magazine, deliver it in the mold, and discharge the matrix when desired; to provide anew matrix feed adapt-- ed to be adjusted so that the matrices can be fed in such a way that any desired number ofv plates can be cast from each matrix, or a plurality of plates from any matrix or matrices and a: diiierent number from the others, or a continuous series of plates from a single matrix to provide a magazine capable of accommodating matrices of different sizes; to provide for delivering the matrices by means of a following matrix or dummy matrix pushing each matrix out of the mold; and to provide an improved matrix. The invention also involves improvementsin various details of construction as will appear hereinafter. 1

Reference is to be had to the accompany ing drawings, in which- Figure 1 is a plan of a fiat stereotype plate casting machine constructed in accordance with this invention with part of the mechanism removed:

Fig. 8 is a sectional view like Fig. 7 show" ing the parts in a different position;

Fig. 9 is an elevation of a portion of the matrix magazine; and

Fig. 10 is a plan of a matrix suitable for use in this machine.

This invention is shown in a form for casting fiat stereotype, plates and as em bcdying aframe 30. At one end of the frame is a main transverse shaft 38 which by bevel gears 39 drives a longitudinal shaft 40 at the front side of the machine. On this shaft is a: cam 140' driving the pump plunger 145' inthe melting pot 146. This supplies metal at intervals to the casting;

box 9395. This is operated by a cam 1:06

on the shaft 40, but the mold operating mechanism is not shown.

At one side of this frame 30' are a pair of along the supporting brackets 41. These.

flanges project inwardly a short distance and serve to guide the corners of the matrices. On the delivery side of the magazine the side members are adjustably held together by means of cross bars 46. One of the side members. is firmly secured to its bracket and the other is adjustable thereon. Both ofthe side members are provided. with two slots in which the ends of these cross bars 46 extend and the latter are screwed or other wise fixed to these side members in the slots and are provided with fastening. pieces a7. Each of the cross bars 46 is provided" with a longitudinal slot. 48 through which pass screws or bolts 49 by which itis secured ad.-

justably'to the other. side member. In this;

way, the distance apart of the side members; and therefore, the width and length of the magazine, can be regulated as desired so as to provide for matrices M of any desired width and length.

Extending along the side of the magazine are a pair of reciprocable rods 50. On each of these rods are mounted two fingers 51 which project toward each other through horizontal slots 52 in the side members of the magazine and are provided at their inner ends with supports 53 in the magazine on which the matrices are supported, as indicated more particularly in Fig. 7. The matrices, are dropped by the logitudinal motion of these supports 53 which permits a single matrix to be dropped at a time on a central and two side suppons 54. Adjustably mounted on the cross bars are retaining bars 55-55 extending inwardly and spaced from the bottom of the magazine a distance suflicient to permit the matrices to be discharged under them.

The rods 50 are guided in boxes 56 supported bv the fla ges 4-4 and 4:5 and by boxes 57 supported at the other ends of the side members 42 and 43. On each of the rods 50 is a key 58 on wh ch the fingers are adjustable longitudinally. They are held in position by screws 59. The dropping of the matrices one by one is accomplished as follows :Each matrix is provided with a pair of opposite edge notches M near one end, and with a pair of similar opposite edge nochcs M at a greater distance from the other end. These notches are all of a shape and size to permit the supports 53 to pass throughthem, and are the same distance apart as said supports. The matrices are placed in the magazine alternately, that is, so that notches M and M are alternately at the head or feeding edge of matrix. When the rods 50 move forward, if the supports register with the notches, the bottom matrix will drop and the next matrix will rest on the support (Fig. 8). Then'on the completion of the reverse motion the second matrix will drop.

In order to move the rods 50 the shaft 40 is provided with a gear or pinion 61 wh ch operates a gear 62 on which is mounted a double throw cam 64:. Gear 62 rotates on a stud 63. Th s cam operates a spring-pressed cam roller 65 on a lever 72 which is conncctcd by screw 73 to lever 66 which is provided with a gear segment 67. This gear se ment meshes with a pinion 68 and turns the same periodically so as to o:cillate a pinion 70 and shaft 69, and reciprocate the .pair of rods 50 which are provided with racks on the bottom. This carries the fingers 51 back and forth periodically and uniformly so as to deliver the matrices under them, as has been described. To adjust the throw of the lever 66 to accommodate the location of thenotches ll and M a .rod 66 is pivoted to the lever and has an adjustable collar 66 which engages the bracket on which the rod is mounted. The lever 66 and therefore the roller 65, is yieldingly held in position by a spring 66. The screw 7 3 can be removed so as to leave the lever 66 free to cast any desired number of plates from a single matrix.

On the shaft 40 is located a cam which operates a spring-pressed forked lever .76. By means of a lever 77 this reciprocates a slide 78 which is mounted on a guide or support 79. This slide carries a pair of ears 80 supporting a rod 81 on which are mounted two hubs 82 each having a pushing finger 83 thereon. One of these is adjustable along the rod to provide for matrices of dilferent widths. Every time the roll 65 comes either on the low or high part of the cam6l the slide 78 is moved to discharge a matrix from the magazine. If it is desired to deliver matrices at alternate rotations of the shaft 40, so as to cast two plates from each matrix the crm (ii is changed. In this case the cam would have one high and one low part of approximately equal length. This slide 78 then moves forwardly and the fingers 83 which come up between the brackets 4L engage the rear of the matrix deposited thereon to push it out of the magazine, as shown more particularly in Fig. 5.

The side member 42 is shown as stationary, and the side member 43 is shown as provided with a projection 85 having slots to move in vertical guides 92 on the frame,

and carries the lower casting box 93.

The upper castirg box 95 is supported on two brackets 320 on which are standards 321 carryirg rods 322 and 332. The upper box is supported from the rods by plates 323.

Through the bases of the plates 323 pass thilnbles 329 which extend slightly below the bottom thereof. A bolt 330 extends through each thimble and these bolts fasten the upper box to the standards 321. The rod 332 rests in open slots on the brackets 320.

The matrices are discharged from the magazine under the end gages of the casting box and positively moved into register with the side gages by means of the pusher fingers 83.

T hen the supporting plate 91 is raised by a cam 106 on the shaft 40 by means notshown. 1

Whenrhecasungbexes close another plate will becas't from the same matrix u-nl'essanother one or'a dummy is fed into "the casti-ng bein In thatcase the old matrix will be forced outofthe box by the new matrix guided bythe end gagesand'drop' at the rear of the frame.

Inpperation the matrices areplaced in'the magazine with the notches M and .M arranged alternately so that .as the feeding rods mo'vefback-and forth-one ni'at'rix will be fed down "at the end of the forward stroke and'the next one atthe end of thereverse stroke. When" it is desired to operate jthe machine one or a definite number of times without casting a plate, one or'more' dummy matrices with their corners cut away are placed in the magazine. Under ordinary conditions 'a 'm'atrix will befed in'to the mold under the end gages Which hold its edges "on the lower casting box. rises, lifts the top section a very slight distance and brings the parts into registration with the-nozzle149 ready for the casting of 25 i "a plate. Then the lower box moves down. The upper box remains substantially in the first position with the'cast plate held by the side gages Which underlie its edges, as has been stated.

It will be seen therefore that one plate 'canbe'cast from each matrix, or any desired number, or a plurality of'plates can be cast from the first'or any'particular matrix and a difierent'number from the'rest of them, or a continuousseries of plates can-be-cast from a'single matrix. It will be seen also that the used matrices are pushed by a succeeding matrix or dummy from theca'sting' box and that the dummy'matrice's" will be delivered in the same way. The various mechanisms are adjustable in 'allnecessary Ways to take care of plates of difi'erent'sizes.
