TYPECASTING AN D LINE-FORMING MACHINE.

Specification of Letters Patent.

Patented Mar. 8, 1921.

To all whom it may concern:

Be it known that I. EDWARD E. VILSON, a citizen of the United States, residing at Cleveland, in the county of (Juyahoga and State of Ohio, have invented certain new and useful Improvements in Typecasting and Line-Forming Machines, of which the following is a specification.

This invention relates to a new and novel improvement in type casting and line forming machine and has for its object to provide a means for carrying a large number of different sizes and face of type or type matrices in one machine. and for bringing these different type or type matrices into position for printing or casting and for the purpose of forming type letters to be rsed in printing.

Further objects of the invention are to provide a plurality of holders in which type or type matrices may be carried and independently used and stored in a convenient manner to be delivered to a central printing or casting point. a print or cast being made therefrom and the type or matrix delivered back into the container, magazine or rack.

Still further objects of the invention are in the provision of means for locating the propencarrier in registry with the printing or casting point, means for disposing of the printed or formed type face in a convenient and eiiicient manner, the provision of a suitable mechanism for controlling the proper movement of the carriers in a rapid and efficient manner and the provision of a machine which will be simple and durable. nominal in cost and capable of serving wide usage.

T 0 this end the invention consists in the certain construction and combination of parts which may best be described in connection with the accompanying drawings and particularly pointed out in the following specification and claims.

Reference being had to the accompanying drawings wherein like reference numerals designate similar parts of reference throughout the various views. Figure 1 is a side elevation of the machine: Fig. 2 is a plan view drawn to a large scale: Fig. 3 is a horizontal section taken on the line 33 of Fig. i: Fig. 4 is a transverse section on the line 1-4 of Fig. 1: Fig. 5 is a similar section as indicated by the line 5 of Fig. 6: Fig. 6

is a sectional detail on the line 6-6 of Fig. 4; Fig. 7 is a similar detail on the line 7-7 of Fig. 4; Figs. Sand 9 are sectional details of the matrix clamps; Fig. 10 isa perspective of the type stick; Figs. 11 and 12 are sectional details corresponding to the linesll- 11 of Fig. 2 and 12-12 of Fig. 11; Fig. 13 is a perspective view of the matrix carrier one of the matrices being partially removed; Fig. 14 is a perspective view of a type letter; Fig. 15 is a perspective view of a type face as it emerges in its completed form from the machine; Fig. 16 is a detail in perspective of the mold disk or wheel.

The invention consists of a table 1 supported upon legs 2 at a convenient height for operating. On the top of the table and at each end thereof are supported front and back frames 3 and 4, respectively. These frames are secured equidistant from each other by being bolted at the bottom to the table top and at the top by cross bars 5, and are each provided with an overhanging portion 6 which permits a cage or frame 7 to slide longitudinally back and forth upon tracks 8 which extend at right angles to and are made as a part of the frames 3 and 4. The cage 7 is composed of end and side members 9 and 10 respectively and is permitted to freely move upon the aforesaid tracks upon anti-friction rollers 11 secured to the sides 10 and said cage supports the type or matrix carriers which will now be described.

As previously stated, the carriers of the type or type matrices must be so constructed and stored as to permit of independent use and positioning with respect to a central casting point. lVith this end in view I have designed a boxed carrier 15 provided with separate compartments 16 in which are placed the type or-type matrices. and said type or type matrices each comprise a rectangular plate 17 upon one end of which is stamped or elcctrotyped a type 18 or type matrix. The plates 17 are retained in their respective compartments 16 by a cover plate 20, the edges of which are dove-tailed to occupy like recesses 21 in the=carrier 15. The carrier 15 is further provided with interlocking hinge members 22 and 23 at the top and bottom. so that they may be assembled in the form of a bar or chain of carriers. each bar containing two or more carriers, and as shown in the drawings, Figs.

*ferent font.

4 and 5, the bar or chain comprises five carriers and each carrier may confine a series of type or type matrices or characters of a dif- At the top said carriers are secured by means of their hinge joint to a bar-carrying plate 25 and said plate is provided with ears or lugs 26, which rest upon the aforesaid tracks 8. These lugs 26 may be provided with anti-friction rollers to facilitate their free movement upon said tracks, but this is optional and therefore has not been illustrated, and, as clearly illustrated, a lurality of said plates are confined withm the frames of the cage 7.

The aforesaid frames 3 and 4 are provided at their middle with vertical flan ed slideways 28 which terminate on a p ane wlth the top surface of the tracks 8 and extend downwardly to a point just above the casting.

or mold wheel, which will be hereinafter described, and a pair of sliding conveyors 30 are adapted to move within each slideway, which conveyers are provided with studs 32 which project outside the limits of ,the frames 3 and 4 and are engaged by the slotted ends of a pair of levers 35 which are located outside of the frames 3 and 4 and are pivoted at their ends upon a shaft 36 which has a bearing in and extends between and through the foresaid frames, and said levers are adapted to be operated by links 37 pivotally secured at one end to the middle of the levers These links are provided at the opposits end with slots 38 in which are engaged a second pair of levers 39 pivoted upon a shaft 40 which extends through and has hearings in the aforementioned frames 3 and 4. The aforementioned levers 39 are provided with a lost motion connection with the levers 37 for a purpose to be hereinafter .described, and are in turn each operated by a link 41 having connection with a crank arm 42 securely fixed upon a third shaft 43, which has bearing in the frames 3 and 4, and which is manually operated by a crank 44 provided with an operating handle 45. It is evident that upon motion being iven to the crank 44 and a connection established after a predetermined time with the levers 35, said motion causes the conveyers to be moved vertically within the slideways aforementioned, and the method of selecting the proper bar of matrix carriers preliminary to this movement will now be described.

The hereinbefore referred to cage 7 has secured to it a rack 50 by means of su porting members 51 which are secured tli and which extend beyond the outside limits of the frame 3 and said rack is engaged by a spur gear 53 mounted u on a shaft 54 having suitable bearing in t e overhanging portion 6 of the frames 3 and 4. This shaft has also secured thereon a bevel pinion 55 which meshes with alike inion 56 upon a substantially vertical she 57, and said shaft is ereto driven through a like pair of bevel gears 58 by a crank 59. Said gears 58 are suitably mounted in a bearing member 60 supported upon the top of the table 1. The shaft 61 upon which the crank handle 59 is mounted also has secured thereto a disk 62 and said disk is provided with a series of graduations about its outer circumference which are marked according to the character that it is desired to select. In this manner the crank 59 is rotated until the indicating finger 65 points out the character desired, motlon being transmitted through the gearing and rack before mentioned to the cage 7, and the assembl of matrix bars are caused to move longitu inally upon the tracks 8 until the proper bar of matrices is in alinement with the slideways 28. At this time the lugs 26 rest upon the top surface of the conveyers 30 and upon motion being transmitted to the levers 35 the bar or chain of matrices is caused to descend vertically with the conveyers within the slideways 28.

After determining the proper character or letter it is desired to cast, it is next necessary to determine the proper font or form of that same letter or character, as it will be remembered that each bar of matrices will carry a pluralit of different fonts. This is accomplis ed by means to limit the downward vertical movement of said bar, and consists of a stop slidably mounted in alinement with the slideways 28 and substantially at the middle of the table 1, and said stop is operated by a rack 71 havin engagement with a spur gear 72 driven b means of an operating wheel 73. A lura ity of graduations 74 upon the face of the stop upon coming in alinement respectively with the top plane of the table will determine the exact font of type coming in registry with the proper point of the casting ap aratus as will ap car more clearly hereina er.

t will be obvious that after the matrix has been located definitely with respect to the proper casting position it is essential that the same be effectively clamped thereagainst, and means for accomplishing this result consists of a swinging carrier clamp or vise indicated generally at 110 and illustrated in detail in Figs. 8 and 9. Said vise is pivoted at its lower end upon an arbor 111 securely mounted in a suitable bracket formed as part of the frame 4 and is adapted to be swung into and out of engagement with the carrier 15 by a pair of horizontal arms 112 secured at one end to said vise by means of a shaft 115 which extends transversely of the frames 3 and 4 and is securely fixed to said vise by means of the brackets 116, and said arms are given a reciprocatory movement by cams 118 the extreme outer ends of the shaft 40 en agi a pair of rollers 118 secured to the ends of iille arms 112. As clearly indicated in Fig. 1

roper the arms 112 are slotted at one end to permit bearing to be had upon the shaft 40. thus confining them in such a manner as 'to keep them in the proper engagement whereby motion may be-transmitted thereto. The vise or clamp 110 is provided at its upper end with a central partition 120 and at each end thereof with movable members 121. The members 121 are normally thrust outwardly or away from the partition 120 by springs 1:22 and at the time of clamping the carrier in place are adapted to move inwardly or toward the partition 120, so as to effectively clamp the carrier in the space 124, bythc beveled edges 125 engaging the beveled surfaces 126 of wedge blocks 12? se cured to and supported by the frames 3 and -l. This movement takes place onlywhen the vise is thrust in a direction toward the casting or mold wheel. Upon referring par ticnlarly to Fig. 7, it will be seen that the clamp further supports. by means of a pair of arms 130, a strap member 131 which is so positioned as to engage the opposite side of the carrier 15 to that which 18 engaged by the clamp 110. This is provided for the purpose of freeing the matrix from the formed type face after same has been cast and the action takes place simultaneously with the freeing movement of the clamp from the carrier 15.

Upon reference particularly to Figs. 4 and 5 it will be seen that two separate bars of carriers depend from the plate .25 and to properly position the same with respect to the proper casting position I provide an index 135 supported in such a manner by the side frames 3 and -l as to separate them the proper distance preliminary to their positioning themselves within the clamp 110.

The casting apparatus comprises a casting or mold wheel in the form of a steel disk provided with a hub portion 76 which permits it to be mounted upon the end of a horizontal shaft 77 located between the frames 3 and 4 and supported by a bearing 78 secured to the table 1. The wheel 75 is further provided with a plurality of rows of rectangular tangential openings 80 and with a second series of openings 81 spaced 90 degrees apart. The aforementioned openings S0 allow the molten metal to enter the matrices and form the stem of the type face as will appear more clearly hereinafter.

The wheel is intermittently rotated onequarter turn upon each selection of type face and this is accomplished by means of a bevel pinion 85, Fig. 3. loosely secured upon the opposite end of the shaft 77. and said pinion has formed thereon a hub portion 86 provided with ratchet teeth 87 which are engaged by a ratchet collar 88 splined to said shaft. and normally held in engagement with the teeth 87 by a spring 89 interposed between said collar and the bearing 78. The

bevel pinion is rotated at the proper time by means of a gear segment 90 provided with skew teeth 91 and is fixed to the shaft 40.

As before stated, the openings 80 in the mold wheel 75 form the stem of the type faces. and as the wheel rotates through onequarter turn it carries with it the formed type face. It is therefore obvious that ejecting means must be provided to remove the formed type faces from the mold wheel, and said means consists of a plurality of ejector rods 95 equal in number to the openings 80 and which are slidabl mounted within an extension bearing 96 ormed as part of the main bearing 78 and secured at one end to a head 97 which has pivotally connected thereto an arm 98 receiving its motion throu h a crank 99 secured upon the shaft 43. T ie slotted connection at 99 between said arm 98 and crank 99 is so constructed as to permit of considerable lost motion being had therebetween. The aforesaid rods 95 are further provided with reduced ends 100 which enter the openings 80 in the mold wheel and thereby effectively eject the formed type face. It is further necessary to provide a means for positioning the mold wheel in an exact relation to the type matrices and this is accomplished by an adjuster rod 101 provided at one end with a reduced portion 102 which enters one of the openings 81 in said mold wheel and has its opposite end secured to the head 97 hereinbefore referred to.

Means for supplying molten metal to the rear of the mold wheel and through the openings 80 comprises a metal pot, pump and heating appliance which is not shown in detail in the drawings, as there are many different appliances of this class and the selection of these parts were left to be adapted to the needs of the machine, therefore the metal pot only is shown and is indicated at 140, for holding the molten metal, constructed with a jacket similar to those used in other type or slug casting machines and with a nozzle 141 opening directly upon the rear of the aforementioned mold wheel, the nozzle being so constructed as to form it shutoff back ground for those openings 80 of the mold wheel which are not in use. The metal pot 140 is pivoted to the base plate at 142 in such a manner that the swing of the said pot will carry the nozzle over and directly in line with the proper opening in the mold wheel. The movement of said metal pot may be controlled by means of suitable links or levers in any convenient manner to swing the same and in order to place the nozzle in the proper position. The foregoing con- 1 strnctions are well known to the art and therefore require no further illustration or description.

A plurality of openings 80 in each set is provided, for the following reasons; the cage provided with a solid fiat surface mouththe back of the letter.

piece with only one orifice for the metal to e forced through by the action of the amp located on the inside of the metal pot. Vhen the letter is casting. this flat surface forms a back wall for the holes in the disk except the hole which comes in alinement with the opening in the metal pot mouthpiece. When the mouthpiece is clamped against the disk on one side of the wheel, the matrix carriage is clamped against the other side with the letter to be cast resting in direct alinement with the hole in the mouthpiece. is forced through the orifice of the mouthpiece, into and through the hole in the disk,

and into the matrix where it fills the matrix, Should it hap ienthus forming the letter. to be a thin letter to be cast there woulr be but one stem at the hack of the letter, but should it be a wide'let-ter, the metal being forced over to the edge of the matrix, it

eutcrs the other one or two holes in the disk and thus forms one or two or more stems at This is for the purpose of securing the letter more firmly to the slug when the slug; is cast onto the letter, as the wide letter. would have one or two or more stems'around which the base slug would be cast. Then in casting the lower case letters the metal pot mouthpiece is shifted back so as to bring theorifice in the mouthpiece into alinement with the fourth hole from the right. It will he noticed that all six of the ejector rods work simultaneously immediately after the wheel adjuster (101-402) thus entering all' holes in the disk and ejecting the letter, whether it be in the first three holes or the second three holes of the mold block.

As before described the formed type faces are ejected from the mold wheel by the ejector rods 95. and in order to keep the same' in their successive order a type stick or magazine indicated generally at 150 is provided.

Saidtype stick consists of a face plate 151 provided with a vertical slot 152 and secured to a back plate 153. A second plate which shall be termed the letter slide 154 is mounted directly in back of the plate 151 and spaced fr 0m the back 153 a distance equal to the thickness of the type face, andsaid slide is permitted a vertical movement between guideways 155 carried by the back 153 so that when a letter is cast in the open- 'iug indicated at 80' the slide may be moved The metal up or down by the handle thereon to'allow the slot 156 in the slide 154 to adjust itself to the arc defined by the opening 80* at one- (uartcr rotation of the mold wheel. The ornred type face is then ejected with the type face between the back 153 and the slide 154 with the stem projecting through the vertical slot 156. This type stick is pivotally mounted at the bottom 'end as indicated at 160 to a suitable bracket 161 carried by the table top and when the type stick has become filled to its capacity the same is tipped forward and the ty 0 emptied into a channeled or grooved galey for further operation. I

In Fig. 15 I have illustrated in detail the formed t 'pe face which consists of a body portion 110 provided with a stem 171.

With the parts constructed as described and the metal in the metal pot being in condition the first operation is the location of the proper font desired by turnin the hand wheel 7 3. The operator then wit his left hand turns handle 59 until the letter desired comes directly in line with pointer 65. Then with the righthand he throws crank 44 over to right, this brings the arms the nozzle 141 of the metal pot 140 and one of the openings 80 in the mold disk or wheel 75. This movement also turns shaft 40 which throws the clamp arms 112 toward the right, thus clamping the mat carrier-15 snugly against the mold disk or wheel 75, and at the same time it releases the plunger in the metal pot, this causing the molten metal to be forced upward and into and through the nozzle 141 of the metal pot 140 and into the mold disk 75. This movement also throws forwardthe mold wheel adjuster 101 and the ejector rods thus securing the mold disk rigidly in position and ejecting any letter which may be in the preceding openings in the mold disk. After the operator has thrown the handle 44 to the right as far as it will go he brings it back to the left. This movement brings the mold disk 101 and ejectors 95 back into position. at the same time it brings the metal pot plunger hack into position, and also raises conveyor arms 35, this carrying the bar of mat carriers back into the rack and at the same time gear segment 90 fixed to shaft 40, engages the ratchet pinion 85 upon the main shaft 77, turning said shaft and bringing the cast letter into position for ejection and also'brings another series of openings into position to be in line for another mat carrier. Another similar operation ejects the letter just east and the stem llO is then tipiped forward and the ty e emptied by sh mg it out of type stick s ide and into a channeled or grooved galle where it is properly spaced and justifie It is then carried to a slug caster where the type high slugs are cast, thus forming a type high 'printin slu which is ready for use,- by underlaylng t e letters with slug-high metal bases or quads or slugs.
