TYPE-CASTING MACHINE.

Specification of Letters Patent.

Application filed May 26,

Patented Aug. 23, 1910.

1909. Serial No. 498,520.

To all whom it may concern:

Be it known that I, ANDREW E. MILLER,

provements in Type-Casting Machines, of

which the following is a specification.

This invention relates to the art of type making in which is produced individual type characters, such as body and display letters, borders, ornaments, spaces, quads and the like, that are used in type composition.

Heretofore the business of the type founder and printer have been conducted separately and wholly distinct. The printer has been dependent upon the type founder for supplies of movable type, and in consequence the procuring of sorts or the addition to fonts of only a portion of its type characters has been attended with inconvenience, delay and expense.

The present invention has for one of its objects to overcome these difficulties by ex tending the domain of the printer by enabling him, in addition to producing the printed matter, to produce the type instrumentalities by which that matter may be obtained.

A further object is to advance the art by enabling the printer to maintain perfectly faced type, whereby the printed product is always of the highest standard.

A further object is to provide a machine capable of producing various sizes and styles of type of the highest standard quality; to replenish sorts at will; and to permit the recasting of old and worn out type into new and more desirable faces.

A further object is to provide such an organization or combination of the principal elements involved as will enable the desired type to be produced without expert knowledge of type founding.

A further object is to produce a mold constructed of a minimum number of parts and so arranged as to permit of rapid adjustment for changes in the size of the type body, or of the character on said body, without necessitating the employment of expert type founders.

A further object is to provide improved means for regulating the size of the mold cavity, whereby the changes in the size of the cast may be readily and quickly accomplished.

A further object is to provide a mold capable of casting type bodies of all sizes and styles, andmeans arranged to automatically conform to the differences in size of the cast for securely closing the mold cavity during each casting operation.

A further object is to provide a mold formed'of loosely mounted, normally stationary sections, and means for rigidly lock ing the same, said locking means being adjustable to conform to changes in the size of the mold cavity.

A further object is to provide means whereby the size or style of the cast may be readily and quickly changed at will, and the casting operation carried on at relatively high speed irrespective of the size or styleof the cast.

A further object is to provide improved means for ejecting the type after each casting operation.

A further object is to provide an improved mold slide for closing the mold cavity.

A further object is to provide improved means for breaking the jets from the type after the latter have been ejected from the mold.

A further object is to provide improved means for accurately placing the matrix in proper position with relation to the moldv cavity.

A further object is to provide improved means for injecting molten metal into the mold cavity.

A further object is to provide improved means for operating the various moving parts in time with each other, and to so con struct said parts as to automatically adjust themselves to changes in the size of the mold cavity.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings :Figure ing the mold. Fig. 9 is a detail plan view of the mold slide. Fig. is a front end view of the mold and its adjuncts, parts be ing in section. Fig. 11 is a similar view with the mold slide advanced to open the end of the mold. Fig. 12 is a detail sectional view of the mold and its support. Fig. 13 is a sectional view illustrating the matrix carrier. Fig. 14 is a top plan view of the mold base. Fig. 15 is an end view thereof. Fig. 16 is a detail view of the type guide. Fig. 17 is a view of the pump locking mechanism. Fig. 18 is a view illustrating the mechanism for operating the rock shafts in time. Figs. 19 and 20 are details.

Referring to the drawings, designates the supporting base or standard provided with an upper platform or extension 81.

The power mechanism comprises a power shaft 32 mounted in base 30 and geared with a driving motor 33 of any preferred construction. Power is transmitted from the shaft 32 by a pulley 34: mounted thereon and controlled by a clutch 35 operated by a lever 36, as shown. It will be understood, however, that I do not limit myself to any particular form of power mechanism, the form shown being merely for illustrative purposes.

The mold mechanism comprises a mold base pivoted to the platform or extension 31, and supporting two

mold blocks

41, 42, the latter being adjustably mounted. The base 40 is provided with shoulders or abutments 43, at, between which the mold blocks are placed. Tnterposed between the section t2 and the shoulder std is a filler block 45, which is of such proportions as to give the proper bodywise size to the mold cavity 46. In this connection it will be noted that a plurality of filler blocks &5 of different predetermined sizes, conforming to the various body-wise sizes of standard type, are employed, said filler blocks being interchangeable. Thus in order to secure the proper body size of the mold it is only necessary for the operator to selectthe proper filler block and insert the same in a manner to be later described. The jet cavity 47 is formed by jet plates l8 located in a recess in base 10 below the

mold sections

41, 42. A filler block 4-.9 similar to the block may be employed to adjust the size of the jet cavity when such adjustment is desired. I prefer, however, to employ a jet cavity of uniform size for all sizes of the body cavity. The nipple plate 50 is located below the jet plates, and the mold section 4:2 is provided with a rib 51 adapted to form the usual nick in the type body. The mold section 41 is held normally stationary by means of a finger 52 secured to a segmental member 53 carried by a rock shaft 54, said finger engaging a notch 55 in the top face of said block. The member is arranged to abut against a similar member 56 rigidly secured to the mold base, each of said members being provided with a series of holes 57 arranged on an arc of a circle. Said holes are so positioned relative to each other that they are normally out of register, whereby the tension on spring 58 may be adjusted by bringing any two of said holes into register and passing a screw or bolt 59 through them. (See Figs. 1, 2, 3 and 10.) Said spring encirclesthe shaft 54 and through the medium of finger 52 acts to hold the mold block 41 normally against the ejector 60. The ejector 60 is mounted to reciprocate between the

sections

41, 42 of the mold, said ejector being of a thickness conforming to the proper body size of the type that it is desired to cast, and definitely proportioned with relation to the filler block 45. A plurality of such ejectors are employed, each of different body size, and interchangeable, whereby one may be substituted for the other when it is desired to change the body side of the cast. The jet ejector 61 is mounted in the jet cavity at. with a notch 62 adapted to fit over the T-end (53 of a reciprocating crosshead 6%, the jet ejector being provided with a similar notch 65, adapted to fit beneath said T-end. The setwise size of the mold cavity is obtained by limiting the backward throw of the ejector (30, and for this purpose I provide an abutment 66 secured to the forward end of an adjusting screw 67, said screw being carried by a shaft 68 controlled by an index wheel 69. In order to aid the operator in securing the proper set, the wheel 69 is provided with graduations conforming to the various predetermined adjustments, and arranged to register with a stationary pointer 70.

The crosshead 64: is reciprocated by means of a bell-crank lever 71 mounted upon a rock shaft 72 and forked at 73 to engage a pin 74L in said crosshead. The depending arm of said lever is provided with a roller 7 5 which rests upon a cam 76 provided with a protuberance 77. A spring 78 encircling the rock shaft 72 tends to hold said crosshead normally retracted.

The outlet side of the mold cavity is closed by a mold slide 80 mounted to reciprocate in a guide 81 formed adjacent the forward end of the mold base. The body of said slide is deflected inwardly, that is, turned in from the straight line, to form a member 82 adapted to fit closely against the forward ends of the mold sections 41, 4L2, to close the cavity &6, being normally held in close contact with said mold sections by means of levers 83 pivotally mounted at- 84: and provided with approximately flat faces bearing against the outer face of said slide, an antifriction roller 85 being carried by said levers. To the upper ends of levers 83 is connected a link 86 passed through a guide 87,

The type ejector 60 is provided 'a spring 88, the tension of which is con-' trolled by a nut 89, serving to hold the flat faces of said levers firmly against the outer face of slide 80, whereby the latter will fit closely against the forward ends of the mold sections. The mold slide is also provided with an internal overhanging portion provided with an opening 91. Said slide is also provided with an integral downwardly bent out-turned finger 92 for breaking the jets; an abutment 93 (see Fig. 6) is carried by the slide 80 and arranged to engage the mold block 42 in its forward movement, to limit the movement of said slide.

The mold slide 80 is reciprocated through the medium of a rock shaft 94 mounted in suitable bearings and provided with a cam arm 95 engaging the cam groove 96 in the rotating cam member 97. To the forward end of said rock shaft is secured an arm 98 which pivotally supports a yoke 99, the latter being in turn pivoted to the slide 80, as indicated at 100. The yoke 99 is provided with a finger 101 provided with a seat for one end of a tension spring 102 carried by arm 98, the tension of said spring being regulated by means of nuts 103 working on a threaded rod 104.

The matrix is mounted in a carrier 111 (Figs. 11 and 13) arranged to reciprocate through the openings 91 in the mold slide 80. Said carrier comprises a block provided with a plurality of adjustable matrix clamping members 112 controlled by clamping screws 113. Said block is also provided with a slot 114 to receive a supporting pin 115 mounted in the forward end of an operating lever 116 mounted on a rock shaft 117. The

pin 115 is provided with a tapered head 115 arranged to engage roller 85, whereby the arms or levers 83 are moved out of engagement with the mold slide as the matrix. carrier is raised. A spring 118 encircling said shaft 117 acts to hold said matrix carrier normally retracted from the mold cavity. To the rock shaft 117 is secured a de pending arm 119 provided with a pin 120, and to rock shaft 54 is secured a similar arm 121 provided with a pin 122 (see Fig. 18). Said pins and 122 are engaged, respectively, by

slots

123, 124, in a link 125 connected to a cam arm 126 arranged to engage a cam 127. The slot 124 is made longer than slot 123, whereby arm 121 will remain at rest during a portion of the time that arm 119 is moving.

The metal supply mechanism comprises a metal pot 130 adapted to contain the molten metal, suitable heating devices 131 (see Fig. 2) being employed for maintaining the metal in the molten condition.

The metal injecting mechanism consists of the pump casing 132 provided with openings 133, and closed at its lower end by a plug 134. Mounted within. the casing is a plunger 135 provided with the usual nipple or outlet 136. A rock shaft 137 is mounted in suitable bearings 138 and serves to support a yoke-like lever 139 pivotally connected at its forward end to the pump casing 132, the rear end of said lever being provided with a roller 140 arranged to engage a cam 141 having a depression 142. Mounted on said rock shaft is a bell-crank lever 143, one arm of which is provided with a roller 144 in the path of a second depression 145 in cam 141. The other arm of said bell-crank lever is forked to receive one end of a finger 146 pivotally connected thereto, the other end of said finger being pivotally connected to a depending plunger operating member 147. Said member is provided with a pin 148 arranged to enter the forked end of a lever 149, said lever being extended through casing 132 and plunger 135, and pivotally mounted at 150 in a depending lug 151. The rear end of finger 146 is provided with a stud 152 which is connected by a spring 153 with a similar stud 154 on lever 143. The roller 140 of lever 139 is held normally in engagement with the cam 141 by means of a yoke 155 straddling the metal pot and connected to lateral extensions 156 of lever 129. Said yoke is adjustably connected to a rod 157, preferably by a screw thread, said rod in turn, being encircled by a helical spring 158, one end of which bears against an adjustable abutment 159 and the other end against a stationary collar 160. To said collar is pivotally connected a spring pressed latch 161 arranged to engage a lip 162 carried by a nut 163 on said rod 157, whereby the yoke may be locked in a depressed position if it is desired to render the pump inoperative. Said latch is controlled by a handle 164.

After being cast the type are delivered upon a typeway comprising two guide members 165, carried by the

adjustable members

166, 167, respectively. The member 166 is normally stationary whilethe adjustable member is arranged adjacent an abutment 168. The adjustment of said members is accomplished in any suitable manner, pref erabl-y by a set screw and slot connection as indicated at 169.

If desired the molds may be artificially cooled by water or other refrigerating fluid, and for this purpose I show a tank 170 from -which the cooling fluid is drawn by a pump 171 and forced upward through a pipe 172 provided with branches 173 leading to the

mold sections

41, 42, respectively. From thence the return is through pipe 174 to said tank. The pump 171 may be operated by means of a sprocket chain 175 connected with the main shaft 32 in any suitable manner.

The

cams

76, 97, 127 and 131 may be arranged independently, but for convenience they are all shown as formed on a single member C mounted on a shaft 180, said shaft being rotated by means of a pulley 181 secured thereto and connected by a belt 182 with pulley 3a. The speed of said cams may be varied in any preferred manner.

The operation is as follows:The burner 131 is first ignited for the purpose of bringing the type metal in the pot to a molten condition and to maintain the same in this state. The matrix is secured in position in the carrier 111 and the latter attached to the operating arm 116. The type ejector 60 of the desired bodywise size, and the ct ejector 61 are then attached to the crosshead 6% and interposed between the mold blocks 4L1, 12. The filler block l5 corre sponding to the bodywise size of the ejector is then inserted between the abutment a4 and the mold block 42, whereby the latter is accurately moved to a position to provide the proper bodywise size for the mold cavity. The setwise size of the mold cavity is obtained by adjusting the wheel 69 to bring the proper markings in register with the pointer 70, and thereby moving the abutment 66 to such a position as will interrupt the movement of the ejector at the proper point to give the required size to the mold cavity. After the parts have been adjusted and placed in their various positions, as described, the pump is released from the yoke 155 and the clutch lever 36 is operated to connect the various parts with the power. The various cams on cam member C are arranged to act in time with each other. The crosshead 6 1 under the influence of spring 78 is held normally retracted with the rear end of the ejector against the abutment 66, the forward end of the ejector 60, and the corresponding end of the jet ejector 62, forming one side of the mold cavity, and the mold blocks 11, 12, each forming one side of said cavity. The cam 96 is so timed that the mold slide 80 is first moved to a position whereby'the inturned member 82 will close the end of the mold cavity and form the fourth wall of the latter, being held tightly against the mold blocks 41, 42 by the levers 83. As the mold slide reaches its position the cam 127 through link 125 rocks the shaft 117, causing arm 116 to bring the matrix carrier downwardly through the opening 91 in said mold slide. The movement of the link 125 is such as to increase the tension on spring 58, thereby forcing the mold block a1 closely against the ejec tor while the latter is at rest, to make a tight oint and to accurately square the faces of the mold cavity. As the cam member proceeds with its rotation the roller 140 drops into the depression 1&2, thereby rocking shaft 137 to bring the roller 14% into contact with the cam 141, and immediately thereafter the said roller le-l drops into the depression 145, and operates the pump piston to inject the molten metal into the mold cavity. It will be noted, of course, that the ends of the latter are closed by the matrix and the nipple plate, respectively. Immediately after the casting operation, the lever 126 is operated to withdraw the matrix and relieve the tension on the mold block tl, allowing sufiicient lateral play of the latter to permit the ejector to move freely between the mold blocks. At the same time the upward movement of the matrix brings the pro tuberance on pin 115 into engagement with roller 85, and moves the levers 83 away from the mold slide, against the tension of spring 88, thereby permitting free movement of said mold slide. As soon as the mold slide is free, it is moved far enough to uncover the mold cavity and then its movement is interrupted, (the cam groove 96 being properly shaped to effect this pause in the operation), whereupon the ejector will be forced forward by cam 76 to eject the type from the mold cavity and on to the mold base 40, and with the jet in line with the jet breaker 92. By this time the cam 97 operates to move the mold slide 80 to the limit of its movement, bringing the jet breaker into contact with the jet and breaking the latter off from the type body in an obvious manner. The foot of the type may then be finished off in any suitable or well known manner.

The operation just described is that which is required for the casting of a single type character, and is continued as long as it is desired to cast type of the particular size and style for which the mold is set. When it is desired to change the bodywise size it is only necessary to substitute an ejector 60 and filler block 15 of the requisite size; to adjust abutment 66 for the proper setwise size, and to place the proper matrix in the carrier 111. Obviously these changes will require but two or three minutes at the outside, and the machine is then ready for the casting operation. If it is desired to change the setwise size .without altering the bodywise size, it is only necessary to adjust the abutment 66. It will also be understood, of course, that the matrix is readily changed at will.

It is apparent that the range of the machine is unlimited and that all sizes of type, from the largest to the smallest, and provided with any desired type character can be accurately cast, and the changes in the size of the cast accomplished with an expenditure of a minimum amount of time and labor, and without necessitating the presence of operators skilled or experienced in the art of type founding.
