MACHINE FOR CASTING PRINTING-PLATES.

Specification of Letters Patent. Patented Aug. 31, 1909. Application filed March 23, 1904. Serial No. 199,551.

To all whom it may concern:

Be it known that I, AMANnUs II. Cnrsn, a citizen of the United States, residing at New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Machines for Casting Printing-Plates, fully described and rep' resented in the foilo'wing specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in machines "for casting stereotype printing plates, and has for one of its objeets to produce an improved mechanism by which stereotype printing plates may be continuously cast from metal flowing from a suitable source of supply.

A further object of the invention is to produce an improved mechanism by which molten metal in continuous flow is convert ed into stereotype printing: plates, suitable dividing mechanism beingemployed to separate the product between the plates.

A further object of the invention is to produce an improved machine for casting; stereotype printing plates, embodyirar simple and eflicicnt constructions for effecting the various steps of the operations to be pm'l'ormed.

'ith these and other objects in view, the invention consists in certain constructions, and in certain parts, improvements and combinations as will be hereinafter fully de scribed and then specifically pointed out in the claims hereunto appended.

Referring to the accompanying drawings:l igurc 1 illustrates in sectional side elevation one form of machine embodying the invention. Fig. 2 is a detail view. Figs. 3 and 4- are side and end elevations respectively of the machine shown in Fig. 1. Fig. 5 is a longitudinal section of the construction shown in Fig. 3. Fig. 6 is a vertical section of the construction shown in Fig. 4.

In the drawings which illustrate a preferred embodiment of the invention, 1 indicates a furnace of any suitable form or construction, and 2 illustrates a melting pot. This melting pot has an outlet pipe 3 which may be secured to it in any suitable manner and wl'iich as shown is supported in one of the walls of the furnace, the outlet pipe beingbolted or otherwise secured to the melting pot. This outlet pipe valve of-any suitable form or construction. In the construction illustrated, this valve is marked 4 and is carried by a stem 5 which is controlled by apasses througl'l aperforation in an arm 6 secured to the upper wall of the pot. The

valve stem is operated by a lever 7 pivoted to a link 8, this lever being pivoted to the valve stem 5 at 9.

While the outlet. from the melting pot may be of any desired configuration, its delivery end should, and preferably will be, broadened so as to be practically as wide as the plate to be cast. In the construction shown, the delivery end of this outlet pipe is formed by a spent 10 which is secured to the outlet pipe by bolts or in any other suitable manner, this 'spoutbeing flattened so that the molten metal is not much thicker than the plate to be cast. of the spout may be of any suitable form, but should be so formed as to deliver the metal directly onto the surface of the cylinder.

In order that the temperature of the metal The delivery end I may be controlled with exactness, so that the I spray might, if desired, be reversed, or that,

under some circumstances, either or both of thcinmight be omitted.

The mechanism for forming the molten metal into printing; plates may be widely varied in its form and construction. As shown, there is provided a frame embodyingstandards 14 in which the several parts of the forming or casting mechanism are mounted. This HKXUTHLDISTH, however constructed, will include forming surf aces so located. with respect to each other as to afford a mold space between them, and these su faccs will be given a movement during the forming or casting operation. The configuration of these surfaces may be varied within wide limits. Preferably, however, both surfaces will be arranged to move in. a curved path.

In the particular construction shown, which illustrates one embodiment of the inwrntion, there is provided a mold forming member comprising a cylinder 15 which may be termed the mohl cylinder. This mold cylinder is provided with heads 11' from :which extend journals 17, these journals iii if desired, be integrally formed, but the con-.

struction shown is a convenient one to construct.

The surface cooperatingwith the mold cylinder may be, as has been indicated, varied widely in form and construction. Preferably, however, this surface embodies a flexible carrier band 13, this type of surface being advantageous where the cooperating surface is a cylinder. The ca'rrierband 18 may be mounted and operated in any desired man- In the preferred construction, however, and as shown, there is provided a pair of cylinders 19, 20, the cylinder 19 being mounted on a shaft 21 sup orted in suitable bearings in the frame an the cylinder20 being mounted on a shaft 22 similarl supported. These cylinders are prefera ly so located with respect to the mold cylinder that the carrier band, which, in the particular construction illustrated, carries the matrix, will be given an upward curve, thi curve being parallel to the curved surface of the cylinder and being at a distance from the cylinder equal to the thickness of the plate it is proposed to cast. In the construction shown, the carrier band is intended tocarry two matrices and the bandis conveniently made in two parts or sections.

The construction by which the band is operated by the cylinders around which it passes may be widely varied. As shown, however, each of the cylinders is provided with agap 23 in which fits a clamping bar 24. Cooperating with each of these clamping bars 24is a wedge shaped clamping bar 25, this bar bein forced into engagement with the bar 24 by means of a suitable screw or screws.

The matrices which are marked 26 may be secured to the band in any desired manner. As shown there is employed a second clam ing bar 27 which also cor'iperates with tie clamping bar 24, being forced into engagement therewith by a suitable screw or screws, these bars seryiug to hold opposite ends of each matrix. The construction will be clearly apparent from Fig. 2.

The bars 24 are arranged so as to move easily into and out of the gaps in the cylinder, a convenient way of effecting this being to bevel the sides of the bars as shown. As the cylinders rotate,"-the means by which they are driven being hereinafter described, the blocks 24- pass into and out of the gaps in the cylinders, the band, when both blocks are disengaged from the cylinders, being driven by the friction of the molten metal on the drum and by thefrietion between the bands and the cylinders.

Suitable means which may be varied widely in construction, are'employed to close the mold space at the sides." Preferably, however, this means will be of such a charactor as to give the cast plate the beveled edge usually present on printing plates. When the side closing means employed is of the character just referred to, that is to say, when it produces lates having beveled edges, this means wil preferably be movable so as to enable it to be moved out of position todeliver the plate and then back into position. In the particular construction shown, the side closing means consist of two pairs of segments 28, (see Fig. 5) these segments being movably mounted on the cylinder, the movement being parallel to the axis thereof.

The means for thus movably mounting the segments may be of anydesired character,

but as shown, the cylinder is provided on each side with aT-slot 29 (see Fig. 6). Each of the segments has de ending therefrom a T-shaped lug 30 which ts snugly in the slot.

The segments may, therefore, be slid away from the middle of the cylinder so as to enable the plate to be removed and may then he slid back into operative position.

When, as in the construction shown, the members which form the mold are rotary members, their movement may be effectedin any desired manner. In the.particular machine illustrated, there is provided a standard 31, and in this standard is mounted a. ower shaft 32, the other end of this shaft eing supported in one of the standards 14. This shaft 32 is shown as provided with the usual fast and loose pulleys and with a driving pinion 33. This driving pinion 33 meshes with a gear 34 which is mounted on a shaft 35 suitablysupported in the frame. This shaft has on it a pinion 36 which meshes with a large gear 37 fast on one of the journals 17 of the mold cylinder. This large gear 37 meshes with driving gears 38, 39 mounted on the shafts 21, 22 before referred to as carrying the cylinders which support the matrix carrier.

When, as in the particular construction illustrated, the machine is intended for con tinuous operation, that is to say, intended to cast a series of stereotype. plates in succession without intermitting the o eration of the machine, there will be provi ed suitable mechanism for dividing the product into the separated plates produced by the matrix or matrices, as the case may be. This dividing mechanism may be of any desired description. As illustrated, there are provided two knives 40 located diametrically opposite each other in the cylinder, the knives each consisting, as shown, of two blades 41. hose blades are guided in their movement by means of bars 42 extending across the cylinder. The knives are norinall flush with or below the surface of the eylini er and are projected at the proper time in order to divide the plates. The mechanism for projecting these knives may be of any desired character, but in the construction shown, two cam disks 43 are provided for this urpose, those cam dish; bei provided witff car grooves 44 of a suitable configuration. The projecting ends of the knives engage these grooves so that the knives are projected and with drawn at )roper times.

It has been heretofore stated that When the segments which form the side closing means are of such a shape as to )roduce plates with beveled sides, they will ie withdrawn at proper times in order to permit the plate or plates to be removed from the cylinder. This withdrawal may be effected in any desired manner. As shown, however, slides 45 (see Fig. 5) are provided on each side of the machine, these slides being preferably curved, as shown,and provided with suitable en aging means which cooperate with engaging means on the segments. gaging means maybe varied, in the construction shown, each of the slides has a groove -16 thereon, and the segments are provided with ribs 47 which run into and engage these grooves as the cylinder is rotated. Each of the slides is provided with a pair of stems 48 projecting therefrom, those stems being connected by means of a cross bar 49 (see Fig. 6). This cross bar 49 has a cam stud 50 (see Fig. 5) mounted thereon, said stud engaging with a cam groove 51 in a suitably formed operated in any desired manner.

cam 51 which is mounted on and rotates with one of the journals 17 of the cylinder 15. This cam is so shaped as to witl'idraw the slides at the proper time for the delivery of the plate, that is to say, when the plate is over a receiving device, if such a device be employed.

It may happen that the blades 41 may not completely out the plates apart, and in order to insure that the plates are divided, an auxiliary hnife will preferably be employed. This auxiliary knife may be mounted and As shown, there 1s provided a cylinder 52, said cylinder being mounted on the shaft 53 suitably supported in the frame of the machine. This cylinder carries a pair of cutting blades 54 which project from the surface of the cylinder. The circlnnfcrence of the cylinder 52 is, in the construction shown, equal to half the circumference of the cylinder 15, and the two surfaces are driven at the same rate of speed, so that the cutting blades 541 come into cutti'ig position twice during the complete revolution of the cylinder and form, where necessary, registering cuts entering from the other side of the plate from those already formed by the blades 41. The surface of this cylinder 52 may also act to steady and hold the cast plate on the surface of dcr. While this cylinder may be driven in any desired manner, in the construction shown, it is driven byagear 52 which is fast While these enthe cylin on the shaft 53 and meshes with the large gear 37 before described.

In the preferred construction and as shown, there will be employed a cooling medium, so as to chill the plate on the cylinder, thus insuring its speedy cooling. The means for effecting this chilling of the cylinder may be of any desired construction, but in the preferred form of the construction, a suitable cooling liquid as water may. be in troduccd into the interior of the cylinder. The means by which .the cooling liquid is introduced may be of any desired description.

As shown, a perforated pipe 55 extends into the cylinder through one of the journals 17, a tight joint being made by a stuffing box 56 of ordinary description, this pipe communicating with any suitable source of liquid su' ply. It is, of course, ap arent that the liquid introduced into the cy inder must be withdrawn, and this withdrawal may be effected in any desired Way. As shown, a perforated pipe 57 is located in the cylinder, this. ipe connecting by means of an elbow 58 wit 1 an outlet ipe 59 located inthe other one of the journa s 17. The pipe 57 is located well below the center of rotation of the cylinder and as arranged will operate to siphon the liquid out of the cylinder. It is apparent that by means of the two pipes referred to a continuous circulation of liquid may be 'kept up through the cylinder.

1n the preferred construction, a plate receiving means will bcemployed, and this receiving means will preferably be of such a character and so located that the plate may be automatically deposited thereon by the cylinder without interrupting its rotation. This plate receiving means may be widely varied in construction. As shown, there are provided two arc-shaped frame pieces 60 mounted on slides 61. These slides move in guideways 62 in a bed block 63 which, in the construction illustrated, is bolted to the bed plate of the machine. struction, the plate receiving surface is formed by means of rolls 64 which are mounted in the arc-shaped frame pieces 60. In the particular construction illustrated, three of these rolls are shown, although it is ap )arent that any number may be employed. n the preferred construction, this plate receiver when in receiving position will be close to the surface of the cylinder, so that the plate may be deposited thereon without being allowed to drop. After the plate has been deposited thereon, the plate receiver will, in a preferred form of the construction, be moved away from the cylinder so that the plate may be readily delivered. It is for this reason that the slide mechanism before referred to is provided.

The means for giving the receiver its movement may be of any deslred character. As shown, however, there is prov ided a shaft 65 In the preferred conmounted in standards 14, this shaft having fast thereon a pair of arms 66 which are slotted at their outer ends and take over ins 67, a in being located on each of the s ides 61: he shaft 65 is a rock shaft, and in order that it maybe rocked, it is provided on its pu'ter end with anarm 68, this aim being rovided with a stud 69 to which is pivote an operating rod 70. This rod'carries a cam roll 71 which cooperates with a cam 72 mounted on the shaft 53 of the auxiliary cutter roll before referred to. The upper end of the rod is forked, as shown, so as to embrace the shaft, the rod being thus guided in its movement.

While the plate might be removed from the plate receivmg device by hand, or in any other desired manner, in the preferred constructdon, mechanically operated removing means will be employed. This removing means may be of any desired construction.

mounted a pair of sprocket wheels 80, and

over these wheels and the Wheels 78 run sprocket chains 81. The shaft 79 may be driven in any suitable manner, as from any moving part of the machine, or may be independently driven. The driving means having no special reference to the present invention, the illustration thereof is omitted in the interest of clearness and brevity.

The operation of the mechanism which has been described will be clearly understood, and a specific recital thereof is not, therefore, necessary. It will be seen that by this mechanism it is possible to cast stereotype plates continuously without interrupting t 10 operation of the machine, and that the number of forms cast will depend upon the number of matrices mounted on the carrier. If the number of matrices be varied, it will be understood, of course, that the cutting mechanism must be varied accordingly, if the machine is intended to be operated to cast-a number of latcs without interrupting its operation. hile, furthermore, in the preferred form of the invention, the matrix carrier and the cooperating surface are both given rotary movements.

The invention is not to be limited to constructions in which such movements are employed, the essential feature of the invention eing, so far as this part of the mechanism is concerned, that the mold travels away from the spout during the casting o eration, so that a continuous flow of metal during the casting operation is insured.

While the machine illustrated embodies the invention in its preferred form, it is to be understood that the invention may be embodied in constructions which differ widely therefrom. The invention is not, therefore, to be limited to the s ecifie construction herein shown and descri ed.
