  • Thelower end of the lever 14 projects inwardly and lies within one of the grooves 16, in which the fiat types 17 are adapted to move.
  • the upper end of the lever is articulated to a latch-bolt 18, and the lever is acted upon by a spring 19, which normally holds the latch-bolt in the position shown in Fig.- 4, with its inner end lying in one of the grooves or recesses 16 to arrest the descent of the types in the grooves or recesses.
  • the lever 14, and latch-bolt 18 constitute an escapement mechanism which lies in a recessed extension or housing 20, at the lower end of a type-case composed of a thin plate 21, Figs. 5 and 8, having at each longitudinal edge a thick rib 22, in each of which is formed two longitudinal grooves 16, one at each side of the plate 21, whereby each type case is provided with two cells or channels, and is adapted to contain one series of type-characters at one side of theplate 21, and another series at the opposite side thereof.
  • the type-cases and escapementmechanisms are alike in construction, and therefore a description of one is sufficient for all.
  • the type-cases are designed to be removable and replaceable for conveniently and quickly changing the font of types, and to accomplish this by a very simple and economical construction, the upper and lower heads 23 and 24 of the magazine are formed with radial grooves or recesses 25 and 26 to receive the upper and lower ends of the type-cases.
  • the lower end of eachtype-case can be easily set in one of the grooves or recesses 26, and the upper end of the type-case can then be moved into one of the grooves or recesses 25, after whichwa vertically movable pin 27, Fig. 4, can be moved downward into engagement with the upper end .of the type-case, thus holding the latter firmly in position while permitting it to be conveniently and quickly removed when occasion demands.
  • the magazine is mounted at its center on a cylindrical column or shaft 28, Fig. 4, on the upper end of which is fixed a yoke 29,
  • the types 17 devised by me are each constructed as best shown in Fig. 15, with a series of slots 31 at one end, one or more of which has its outer end removed or omitted, so that the types can be suspended by the oscillatory hooks and released over the proper type-cases or channels.
  • the construction of the types is also described and claimed in my application, Serial No. 522,489, above referred to, and therefore I will not more fully explain the same in this application, further ent filed October 2l, 1893, Serial No. 488,800.
  • the selections from the type-cases or channels are made by the keys 11, and as the types are released they pass by gravity into the chutes 33 and are received by the rapidly rotating table or wheel 34, from which they are discharged in the order of their selection into a chute 35, Figs. 2 and 4, which conducts the types to the inlet-channel 36, Fig. 9, in one end of a rotary line-carrier.
  • the rotary line-carrier comprises two circular heads 37 and 38, Figs. 9,11,12, and 15, connected bya sleeve 39 fixed on a ahaft 40, Fig. 10.
  • the heads 37 and 38 are rigidly connected by intermediate angular blocks 41, Figs.
  • the angular blocks 41 are each formed with a line-assembling or composing-channel 43, having a shape which corresponds to the outline of the types, the depth and arrangement of the channels being such that when a type is placed therein, with its slotted end lying against the vertical wall of the angular block 41, Fig. 10, the convex end of the type will lie in the plane of the perimeter of the two heads 37 and 38.
  • the convex end of the type is curved in an arc struck from the center of the shaft 40.
  • the assembling or composing-channels 43 are so arranged that they are open one upon the top IIO and the other upon the bottom of the angular blocks, so that they will always lie in proper position for assembling or distributing when the line-carrier is rotated.
  • the line-carrier is so arranged that one of its heads-as 371ies beneath the deliveryend of the chute 35, Fig. 9, and in the outer face of this head 37 is formed the curved or segmental channel or chute 36, which cuts the periphery of the head substantially in the direction of a radius of the latter.
  • the segmental channel iscurved to avoid the shaft 40, and one of its extremities cuts the periphery of the head at a point separated by an arc of about ninety degrees from the other extremity.
  • the head 37 is provided with two of the inlet channels 36, each of which is the counterpart of the other.
  • the form of the channels in cross section is such as to permit the body portion of the type to enter the same.
  • the channels 36 are partially covered by plates 45, thereby forming a curved chute in which the types may slide freely in the direction of their length, as in my application for Letters Patent, Serial No. 488,800, abovementioned.
  • each type is arrested by the elastic or yielding dog 44, such type is acted upon by pins 46 on a rotary transfer-wheel 47 having teeth 48, whereby each type is positively moved into alignment with the lineassembling or composing-channel 43, Fig. 15.
  • each type In the movement of the type into alignment with the line-assembling or composing channel 43, it acts upon a curved foot-piece 49, Fig. 16, on the inner end of a reciprocatory composing-stick or feed-bar 50.
  • the composing-stick or feed-bar 50 yields in the direction of the arrow, Fig.
  • the composing-stick or feed-bar is suddenly forced in the opposite direction by a spring 149, Fig. 11, and thus urges the type into the lineassembling or composing channel, so that the type lies upright against the head 51, of a slide-bar 52, which is adapted to yield as the types accumulate in line.
  • the head 51, of the sliding-bar serves to retain the blank or quad which first enters the channel or space 43 in an upright position, and consequently all the types which subsequently enter are likewise sustained in upright positions.
  • the composing stick or feed-bar 50 is locked for the purpose of compressing and locking the line of type in the direction of its length. This is accomplished by providing the outer end of the composingstick or feed-bar with a roller-bearing 52, Fig. 11, which, when the line-carrier commences to rotate, as will hereinafter appear, passes into engagement with a stationary incline 53, and thence on to a segmental track 54, Fig. 21, whereby the composing-stick or feed-bar is forced inward and rigidly held during a half revolution of the line-carrier.
  • the line of type including the whole number representing a line, or part of a line of printed matter, as well as the necessary spaces and characters, is compressed in the direction of the length of the line, so as to force the types closer together and secure uniformity in the length of the successive lines.
  • lhe support 56 is sustained in position by a yielding plate 56" bearing upon a cam 58 which underlies the support and forms a part of, or is rigidly mounted upon a cam-shaft 59, one end of which is extended through the head 37, and is provided with a lever 60, Fig. 9, comprising two arms 60 and 60
  • the lever-arm 60 is operated by a projection 61 having a beveled outer end and mounted on a type-aligning drum 62, hereinafter referred to.
  • the lever 60 is operated by the projection 61, thereby forcing the cam 58 against the yielding plate 56 and causing the support 56 to yieldingly force the jaw 55 against the edges of the type-plates.
  • a yielding device such as a plate 56, backed by a rubber or other cushion 56, is important, in that it compensates for irregularities, or overthrow of the positively operating parts. For instance, if the throw of the cam 58 were greater than the distance the support 56 could swing when the type are in line in channel 43, the plate 56 would yield and permit proper locking up without danger of any rigid part breaking or becoming strained or injured.
  • the type-aligning drum 62 Fig. 9, which is carried by a shaft 63 journaled upon the main frame at the front of the machine, said drum being of about half the diameter of the line-carrier.
  • the periphery of the drum is provided with a seat in juxtaposition to the projection 61, in whichis seated a metallic bar 64, having a longitudinal groove 65 lying parallel with the axis of the drum.
  • the bar 64 is substantially the same length as chanthe line-carrier that the bar 64 will roll upon and abut'forcibly against the convex ends of the types, the projecting type characters of the types entering the groove 65, and being free from contact with the base of the groove.
  • the action of the bar 64 against the convex edges of the types forces back anyone or more of the types which project more than others, so that the lugs on the outer ends of the types bear against the rib 55*, Fig. 10.
  • the types are aligned, and the entire series is placed in such condition that a perfoot impression can be made by the types in the matrix material, as will hereinafter appear.
  • the next step i in the order of operation is the formation of a type impression in the soft metal or other material which is to form the solid line of matrices from or by which the cast-bar is produced.
  • the matrix material isin the form of a rectangular block 66, Fig. 27,,of soft metalof suitable thickness,and of awidth approximately coextensive with the length of the line-assembling or composing-channels 43.
  • the matrixblock is mounted in, a rotatable holder 67, Figs. 9, 18,19, and 20, which is specially constructed to carry two matrix-blocks which alternately receive the impressions of the lines of types.
  • the matrix-blocks are each arranged to slide longitudinally in guide-ways 68, and on one surface the block is provided with a rack or series of .teeth 69 engaged by the teeth of a pinion 70, mounted on a shaft 71 and having at one end a gear-wheel 72, engaging a pinion 73, on a shaft 74.
  • the shaft 74 is provided witha ratchet-wheel 75, with which engages a pawl 76, acted on by a spring 77, to hold it in engagement with the ratchet-wheel while permitting the latter to rotate in one direction.

  • the ends 89 Fig. 18, of the matrix-block holder are formed in the arc of a circle struck from the center of the shaft 90'on which the holder is mounted.
  • the levers 82 Fig. 9 are each formed with a long arm 91 and a short arm 92. As the matrix-block holder rotates, the long arm 91, strikes a stud or roller-bearing 93 Figs. 2 and 9, on a shaft 94, whereby the lever 82 is rocked and the cam-shaft 83 Fig.
  • each lever 82 is turned to cause its cam 84 to press the yielding plate 85 and move the support 86 for causing the jaw 88 to lock up the matrix-block 66 and hold it in a fixed position in the holder 67.
  • the short arm 92 Figs. 2 and 9, of each lever 82 is adapted to strike a shaft 95, and thereby swing the lever 82 in the proper direction to release the support 86, Fig. 18, and unlock the matrixblock 66, so that the latter can be advanced one step by the rack and pinion 69 and 70, as will hereinafter appear.
  • each matrix-block is successively impressed and shaved, so that the matrix-block is provided with a smooth and bright or lustrous impression surface for every type-impression.
  • the projecting end of the matrix-block is shaved off by a shear-knife 96, Fig. 9, duringthe rotation of the matrix block holder, and before the projecting end of the block has been shaved off, the block is advanced a predetermined distance, or one step, to cause the outer end of the block to project the required distance that it may be shaved ofi by the shear-knife 96.
  • the matrix-block holder 67 Fig. 9 is timed to rotate in unison with the line-carrier, and as the greatest diameter of the matrix-block holder is the same. as the diameter of the line-carrier, the surfaces 89 of the holder roll against the peripheries of the heads 37 and 38 of the line-carrier. During this movement the male type-characters are driven or forced into the shaved end of the matrixblock 66, thereby forming a series of intaglio impressions or indentations which are the converse of the cameo letters or characters of the types, thus producing, asolid line of matrices from which a type-high printing-bar may be cast by the casting mechanism hereinafter described.
  • each carrier block 78 The opposite edges of the recesses 79 in each carrier block 78 are separated such a distance that the end of the bolt 81 entering the recess is susceptible of a limited play therein, so that when the lever-arm 92 first strikes the rod 95, the lever 82 and the bolt 81 will be moved or swung ashort distance without actually moving the pawl-carrier block 78, whereby the matrix-block is unclamped or unlocked, and then the carrier-block 78 is subsequently moved for causing the pawl 76 to move the ratchet-wheel 75 one step, or a predetermined distance, for the purpose of rotating or turning the pinion '70 and causing it to move the matrix-block outward a distance corresponding to the distance the ratchetwheel is moved.
  • the matrixblock is fed outward, so that the previously impressed or indented surface will be shaved off by the shear-knife 96, but previous to the shaving of this impressed or indented end of the matrix-block, the lever-arm 91 strikes the stud or roller-bearing 93 and the matrixblock is clamped or locked rigidly inposition in the matrix-block holder.
  • the end of the matrixblock still projects a slight distance, as shown in Fig. 24, for receiving the impression of the line of type assembled in the rotary line-carrier.
  • the ends of the matrix-block holder 67 are provided with projecting lugs 97 which act upon the rotary mold, and cause it to accurately register with the mouth of the casting-pot, as will hereinafter appear.
  • the rod 95 is suspectible of being shifted lengthwise through the medium of a lever 98, Figs. 2 and 3, so that the inner end of the rod can be moved out of the path of the lever arms 92, of the levers 82, to permit the matrix-block holder to be repeatedly rotated without feeding or shaving the matrix-block.
  • the purpose of this is to produce duplicate castings of the same line of matrices.

JOSEPH C. FOWLER, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO THE FOWLER COMPOSING AND TYPE SETTING COMPANY, OF
CHICAGO, ILLINOIS.
MACHINE FOR PRODUCING TYPE-BARS.
SPECIFICATION forming part of Letters Patent No. 533,285, dated January 29, 1895.
Application filed September 24:, 1394. Serial No. 523,978, (No model-l I C To all whom it may concern.-
Be it known that I, JOSEPH O. FOWLER, a citizen of the United States, residing at Washington city, in the District of Columbia, have invented new and useful Improvements in Machines for Producing Type-Bars, of which the following is a specification.
This invention relates to that class of machines for making type-high printing bars, wherein male types, or types bearing characters' or letters in relief, are released in proper order by finger-key mechanism, and composed or set in a line which is justified and caused to impress or indent some suitable matrix material to form a line of matrices therein from or by which the printing-bar is cast by injecting type-metal into one side of a mold, the opposite side of which is closed by the material in which the line of matrices is impressed or indented.
In prior machines of the character alluded to, it is difficult to produce printing'barshaving type characters which possess the required sharp angles and perfect formation necessary for finely executed work and the high perfection required in the printing art. The chief reason for imperfect work in this method of casting printing bars resides in the fact that the impressions or indentations have heretofore always been made in comparatively irregular or rough and dark, dull or-lusterless surfaces of lead or other soft metal bars or blanks, which are comparativeiy thin and lack the required body or solid foundation necessary for the production of perfect matrices.
1 have discovered that by shaving the matrix block or material, and thus providing it with a smooth and bright or lustrous, or polished surface, the impressions or indentations of the types produce accurate and perfect matrices, with the result that I have obtained type-high printing-bars bearing characters or letters having all the necessary sharpness of angles and susceptible of producing as finely executed printing as type-high printing bars cast direct from or by disconnected and interchangeable matrices, or type-bearing female characters or letters assembled in aline. I have also discovered that by impressing or indenting into the shaved surface of a body of soft metal of comparatively largellimensions, the metal is compressed or consolidated and the large body presents a hard foundation for the formation of the matrices, while the edges of each matrix are higher than is ordinarily the case, because the metal flows upward or outward when the impression is made, in a better manner than when the impression is made in a comparatively thin matrix-bar or blank. I
y The objects of my invention are to improve machines designed for producing printing or type-bars by casting from or by lines of matrices obtained by causing male types to indent or impress some suitable soft metal or other suitable material; to obtain superior lines of matrices insoft metal or matrix material; to improve the devices for mechanically handling or manipulating the types; to simplify the construction of this class of machines; to reduce the dimensions of the ma chines and render them susceptible of being conveniently and swiftly operated.
The machine involves several new improvements, and, concisely stated, it comprises a magazine having a plurality of individual removable and replaceable type cases or channelsin which cameoor male types are arranged in columns, and are individually released by finger-key mechanism. The released types fall upon a rapidly rotating table or wheel which delivers them to a curved chute, and the curved chute deposits the types vertically in a line-assembling or composing-channel formed in an intermittently rotating carrier, into which channel the type are successively fed by a horizontal line-composing stick or feed-bar. When the desired line is assembled, the carrier turns, the types are aligned by a rotary-drum, the composing-stick is locked, and the type are rolled into the shaved end of a solid block of soft metal which is locked at intervals in an intermittently rotatable matrix block holder. This holder rotates in unison with the line on type-carrier, and after the impression or indentation is made to produce a line of matrices in the. shaved end of the block of metal, the holder stops in proper position relatively to a mold, into which type metal is injected, for the purpose of producing a type-high printing-bar bearing at one edge a line of cameo or relief characters. During each rotation of the matrix-block holder, the matrix-block is shaved to provide it with a fresh impression surface which is bright or lustrous. While the castingofaprinting-barisbeingeifected,the types are successively delivered into an exit-channel in the rotaryline-carrier, from which they ,are delivered into engagement with an ele- .of the magazine.
vating screw. The screw carries the types to a circular distributing mechanism, and as the types are carried in a circular path, they are automatically assorted into the type-cases or channels of the magazine.
The spacers employed in the machine may be similar in form to the types, and are mechanically handled in the same manner, but all are deposited in the same channel or cell The cast type bars are ejected from the mold and descend through an inclined chute into a galley.
The invention consists in the several features hereinafter described and set forth in the claims, reference being made to the accompanying drawings, in which Figure 1 is a broken side elevation,looking at the left hand side of a portion of my improved machine.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, wherein The numerals 1 indicate parts of a main 11. The hand-lever controls the rotation of the main power-shaft and the fin ger-keys connect by slender rods 12 with vertically slidable pins, as at 13, Figs. 4 and 5, each of which is provided with a beveled upper end bearing against the lower end -of a lever 14 pivoted between its extremities to a pin 15. Thelower end of the lever 14 projects inwardly and lies within one of the grooves 16, in which the fiat types 17 are adapted to move. The upper end of the lever is articulated to a latch-bolt 18, and the lever is acted upon by a spring 19, which normally holds the latch-bolt in the position shown in Fig.- 4, with its inner end lying in one of the grooves or recesses 16 to arrest the descent of the types in the grooves or recesses.
The lever 14, and latch-bolt 18 constitute an escapement mechanism which lies in a recessed extension or housing 20, at the lower end of a type-case composed of a thin plate 21, Figs. 5 and 8, having at each longitudinal edge a thick rib 22, in each of which is formed two longitudinal grooves 16, one at each side of the plate 21, whereby each type case is provided with two cells or channels, and is adapted to contain one series of type-characters at one side of theplate 21, and another series at the opposite side thereof. By this means the dimensions of the magazine are reduced, and its construction is simplified.
The type-cases and escapementmechanisms are alike in construction, and therefore a description of one is sufficient for all.
The type-cases are designed to be removable and replaceable for conveniently and quickly changing the font of types, and to accomplish this by a very simple and economical construction, the upper and lower heads 23 and 24 of the magazine are formed with radial grooves or recesses 25 and 26 to receive the upper and lower ends of the type-cases. The lower end of eachtype-case can be easily set in one of the grooves or recesses 26, and the upper end of the type-case can then be moved into one of the grooves or recesses 25, after whichwa vertically movable pin 27, Fig. 4, can be moved downward into engagement with the upper end .of the type-case, thus holding the latter firmly in position while permitting it to be conveniently and quickly removed when occasion demands.
The construction of the type-case, with two cells or channels in the manner described and shown, is very desirable, in that, as before stated, two sets of different characters can be contained in a single removable and replaceable type-case.
The magazine is mounted at its center on a cylindrical column or shaft 28, Fig. 4, on the upper end of which is fixed a yoke 29,
carrying a horizontal bar 30, formed as an annulus or ring, and provided with pins or projections 30, the linear arrangement of.
which is changed or varied to form a permutation-bar which serves to properly operate oscillatory hooks 31 for automatically releasing the types 17 and assorting them into the type-cases or channels.
The specific construction and operation of the permutation-bar and the oscillatory hooks are fully described andshown in my applica tion forLetters Patentfiled September 8,1894, Serial No. 522,489, and is claimed in that application, for which reason I do not herein claim the same, and do not deem it necessary to more fully describe and illustrate the features, especially in view of the fact that in the present machine I do not confine myself to any particular devices for automatically distributing the types into the type-cases or channels.
The types 17 devised by me are each constructed as best shown in Fig. 15, with a series of slots 31 at one end, one or more of which has its outer end removed or omitted, so that the types can be suspended by the oscillatory hooks and released over the proper type-cases or channels. The construction of the types is also described and claimed in my application, Serial No. 522,489, above referred to, and therefore I will not more fully explain the same in this application, further ent filed October 2l, 1893, Serial No. 488,800.
The selections from the type-cases or channels are made by the keys 11, and as the types are released they pass by gravity into the chutes 33 and are received by the rapidly rotating table or wheel 34, from which they are discharged in the order of their selection into a chute 35, Figs. 2 and 4, which conducts the types to the inlet-channel 36, Fig. 9, in one end of a rotary line-carrier. The rotary line-carrier comprises two circular heads 37 and 38, Figs. 9,11,12, and 15, connected bya sleeve 39 fixed on a ahaft 40, Fig. 10. The heads 37 and 38, are rigidly connected by intermediate angular blocks 41, Figs. 9 and 10, which may be formed in one piece with the heads, but which are preferably constructed as separate parts, and are attached by screws, as at 42, Fig. 12. The angular blocks 41 are each formed with a line-assembling or composing-channel 43, having a shape which corresponds to the outline of the types, the depth and arrangement of the channels being such that when a type is placed therein, with its slotted end lying against the vertical wall of the angular block 41, Fig. 10, the convex end of the type will lie in the plane of the perimeter of the two heads 37 and 38. The convex end of the type is curved in an arc struck from the center of the shaft 40. The assembling or composing-channels 43 are so arranged that they are open one upon the top IIO and the other upon the bottom of the angular blocks, so that they will always lie in proper position for assembling or distributing when the line-carrier is rotated.
The line-carrier is so arranged that one of its heads-as 371ies beneath the deliveryend of the chute 35, Fig. 9, and in the outer face of this head 37 is formed the curved or segmental channel or chute 36, which cuts the periphery of the head substantially in the direction of a radius of the latter. The segmental channel iscurved to avoid the shaft 40, and one of its extremities cuts the periphery of the head at a point separated by an arc of about ninety degrees from the other extremity.- The head 37 is provided with two of the inlet channels 36, each of which is the counterpart of the other. The form of the channels in cross section is such as to permit the body portion of the type to enter the same. The channels 36 are partially covered by plates 45, thereby forming a curved chute in which the types may slide freely in the direction of their length, as in my application for Letters Patent, Serial No. 488,800, abovementioned.
When the shaft 40 is rotated, and the linecarrier is turned until the entrance end of one of the chutes or channels 36 lies in a vertical line, as shown in Fig. 9, said chute or channel will then constitute practically a continuation of the chute 35, so that the types will pass freely from the latter into one of the chutes or channels 36, and will swiftly traverse the latter by gravity until they arrive at the lower end of the chute or channel, where each type is successively arrested by an elastic or yielding dog or stop 44, Fig. 15, pressed by a spring 44 toward the channel or chute 36. As each type is arrested by the elastic or yielding dog 44, such type is acted upon by pins 46 on a rotary transfer-wheel 47 having teeth 48, whereby each type is positively moved into alignment with the lineassembling or composing-channel 43, Fig. 15. In the movement of the type into alignment with the line-assembling or composing channel 43, it acts upon a curved foot-piece 49, Fig. 16, on the inner end of a reciprocatory composing-stick or feed-bar 50. As the type is forced against the foot-piece 49, the composing-stick or feed-bar 50 yields in the direction of the arrow, Fig. 16, and as soon as the type arrives in alignment with the lineassembling or composing-channel 43, the composing-stick or feed-bar is suddenly forced in the opposite direction by a spring 149, Fig. 11, and thus urges the type into the lineassembling or composing channel, so that the type lies upright against the head 51, of a slide-bar 52, which is adapted to yield as the types accumulate in line. The head 51, of the sliding-bar, serves to retain the blank or quad which first enters the channel or space 43 in an upright position, and consequently all the types which subsequently enter are likewise sustained in upright positions.
When the necessary number of types to constitute a line of the required length have been introduced into the line-assembling or composing-channel 43, and when this line is to be impressed into matrix material, as hereinafter explained, the composing stick or feed-bar 50 is locked for the purpose of compressing and locking the line of type in the direction of its length. This is accomplished by providing the outer end of the composingstick or feed-bar with a roller-bearing 52, Fig. 11, which, when the line-carrier commences to rotate, as will hereinafter appear, passes into engagement with a stationary incline 53, and thence on to a segmental track 54, Fig. 21, whereby the composing-stick or feed-bar is forced inward and rigidly held during a half revolution of the line-carrier. By this means the line of type, including the whole number representing a line, or part of a line of printed matter, as well as the necessary spaces and characters, is compressed in the direction of the length of the line, so as to force the types closer together and secure uniformity in the length of the successive lines.
The series of types being compressed longitudinally, as stated, it is necessary to clamp the type plates edgewise, in order to place the cameo or male characters in accurate alignment and firmly hold the type in the line-assembling or composing-channel or space 43. To accomplish this I provide a clamp-jaw 55, Fig. 10, secured to a support 56, pivotally mounted on a shaft 57 fixed in the heads37 and 38. The jaw 55 lies in the open side of the line assembling or composing channel 43, and when the line carrier is in the position shown in Figs. 9 and 10, the jaw 55 lies directly beneath the lower edges of the types as they enter and are moved forward in the line-assembling or composing-channel. lhe support 56 is sustained in position by a yielding plate 56" bearing upon a cam 58 which underlies the support and forms a part of, or is rigidly mounted upon a cam-shaft 59, one end of which is extended through the head 37, and is provided with a lever 60, Fig. 9, comprising two arms 60 and 60 The lever-arm 60 is operated by a projection 61 having a beveled outer end and mounted on a type-aligning drum 62, hereinafter referred to. As the line-can rier rotates, the lever 60 is operated by the projection 61, thereby forcing the cam 58 against the yielding plate 56 and causing the support 56 to yieldingly force the jaw 55 against the edges of the type-plates. This occurs as the movement of the line-carrier is initiated, and when the jaw 55 is forced against the edges of the type-plates the lever 60 rides off of the projection 61, leaving the cam 58 in such position that the jaw 55 is locked against the types. In the subsequent rotation of the line carrier, the jaw 55 is unlocked to release the edges of the types by the lever-arm 60 striking a pin or lug 60,
' frame.
nel 43, and the drum is so timed relatively to The provision of a yielding device, such as a plate 56, backed bya rubber or other cushion 56, is important, in that it compensates for irregularities, or overthrow of the positively operating parts. For instance, if the throw of the cam 58 were greater than the distance the support 56 could swing when the type are in line in channel 43, the plate 56 would yield and permit proper locking up without danger of any rigid part breaking or becoming strained or injured.
In order to place the faces of the cameo or male types in the same plane, should one or more project slightly beyond the others, I provide the type-aligning drum 62, Fig. 9, which is carried by a shaft 63 journaled upon the main frame at the front of the machine, said drum being of about half the diameter of the line-carrier. The periphery of the drum is provided with a seat in juxtaposition to the projection 61, in whichis seated a metallic bar 64, having a longitudinal groove 65 lying parallel with the axis of the drum. The bar 64 is substantially the same length as chanthe line-carrier that the bar 64 will roll upon and abut'forcibly against the convex ends of the types, the projecting type characters of the types entering the groove 65, and being free from contact with the base of the groove. The action of the bar 64 against the convex edges of the types, forces back anyone or more of the types which project more than others, so that the lugs on the outer ends of the types bear against the rib 55*, Fig. 10. By this means the types are aligned, and the entire series is placed in such condition that a perfoot impression can be made by the types in the matrix material, as will hereinafter appear.
I have only explained the construction of one of the line-assembling or composing channels 43, and the elements co-operating therewith, but a similar channel is formed in the opposite side of the line-carrier, and therefore the composingstick or feed-bar and lock-up devices are duplicated at such side, in order that the second line-assembling or composing channel may be brought into a position to receive types from the chute 35.
The line or series of types being set up, compressed, and accurately aligned, the next step i in the order of operation is the formation of a type impression in the soft metal or other material which is to form the solid line of matrices from or by which the cast-bar is produced.
The matrix material isin the form of a rectangular block 66, Fig. 27,,of soft metalof suitable thickness,and of awidth approximately coextensive with the length of the line-assembling or composing-channels 43. The matrixblock is mounted in, a rotatable holder 67, Figs. 9, 18,19, and 20, which is specially constructed to carry two matrix-blocks which alternately receive the impressions of the lines of types.
The matrix-blocks are each arranged to slide longitudinally in guide-ways 68, and on one surface the block is provided with a rack or series of .teeth 69 engaged by the teeth of a pinion 70, mounted on a shaft 71 and having at one end a gear-wheel 72, engaging a pinion 73, on a shaft 74. The shaft 74 is provided witha ratchet-wheel 75, with which engages a pawl 76, acted on by a spring 77, to hold it in engagement with the ratchet-wheel while permitting the latter to rotate in one direction. The pawl 76 is pivotally mounted on a carrier block 78, Fig. 4, adapted to oscillate on the shaft 74, and having at its lower end a recess 79, into which projects the end 80 of an actuating bolt 81, adapted to slide on an oscillatory duplex armed lever 82 which is secured toa shaft 83 Fig. 19, having a cam 84 which is adapted toact upon an elastic or yielding plate 85 Fig. 18, secured to a support 86, which is mounted on a shaft 87 carried by the side pieces of the rotatable matrix-block holder 67. The support 86 is provided with a jaw 88 preferably provided with a serrated face to engage the face 89 of the matrix-block 66, for locking up the matrix-block prior to making the type impression in the outer end thereof.
The provision of a yielding device, such as the elastic plate 85, compensates for overthrow of positively acting parts the same as hereinbefore described with reference to the yielding plate 56*, Fig. 10.
The lock-up devices for each matrix-block are the same, and therefore a description ofone is sufficient for both. The ends 89 Fig. 18, of the matrix-block holder are formed in the arc of a circle struck from the center of the shaft 90'on which the holder is mounted. The levers 82 Fig. 9 are each formed with a long arm 91 and a short arm 92. As the matrix-block holder rotates, the long arm 91, strikes a stud or roller-bearing 93 Figs. 2 and 9, on a shaft 94, whereby the lever 82 is rocked and the cam-shaft 83 Fig. 18 is turned to cause its cam 84 to press the yielding plate 85 and move the support 86 for causing the jaw 88 to lock up the matrix-block 66 and hold it in a fixed position in the holder 67. The short arm 92 Figs. 2 and 9, of each lever 82, is adapted to strike a shaft 95, and thereby swing the lever 82 in the proper direction to release the support 86, Fig. 18, and unlock the matrixblock 66, so that the latter can be advanced one step by the rack and pinion 69 and 70, as will hereinafter appear.
In my present invention, the outer end of each matrix-block is successively impressed and shaved, so that the matrix-block is provided with a smooth and bright or lustrous impression surface for every type-impression. To accomplish this, the projecting end of the matrix-block is shaved off by a shear-knife 96, Fig. 9, duringthe rotation of the matrix block holder, and before the projecting end of the block has been shaved off, the block is advanced a predetermined distance, or one step, to cause the outer end of the block to project the required distance that it may be shaved ofi by the shear-knife 96.
The matrix-block holder 67 Fig. 9, is timed to rotate in unison with the line-carrier, and as the greatest diameter of the matrix-block holder is the same. as the diameter of the line-carrier, the surfaces 89 of the holder roll against the peripheries of the heads 37 and 38 of the line-carrier. During this movement the male type-characters are driven or forced into the shaved end of the matrixblock 66, thereby forming a series of intaglio impressions or indentations which are the converse of the cameo letters or characters of the types, thus producing, asolid line of matrices from which a type-high printing-bar may be cast by the casting mechanism hereinafter described.
The opposite edges of the recesses 79 in each carrier block 78 are separated such a distance that the end of the bolt 81 entering the recess is susceptible of a limited play therein, so that when the lever-arm 92 first strikes the rod 95, the lever 82 and the bolt 81 will be moved or swung ashort distance without actually moving the pawl-carrier block 78, whereby the matrix-block is unclamped or unlocked, and then the carrier-block 78 is subsequently moved for causing the pawl 76 to move the ratchet-wheel 75 one step, or a predetermined distance, for the purpose of rotating or turning the pinion '70 and causing it to move the matrix-block outward a distance corresponding to the distance the ratchetwheel is moved. By this means the matrixblock is fed outward, so that the previously impressed or indented surface will be shaved off by the shear-knife 96, but previous to the shaving of this impressed or indented end of the matrix-block, the lever-arm 91 strikes the stud or roller-bearing 93 and the matrixblock is clamped or locked rigidly inposition in the matrix-block holder. After the impressed or indented end of the matrix-block is shaved off to provide a bright or lustrous impression surface, the end of the matrixblock still projects a slight distance, as shown in Fig. 24, for receiving the impression of the line of type assembled in the rotary line-carrier. The ends of the matrix-block holder 67 are provided with projecting lugs 97 which act upon the rotary mold, and cause it to accurately register with the mouth of the casting-pot, as will hereinafter appear.
The rod 95 is suspectible of being shifted lengthwise through the medium of a lever 98, Figs. 2 and 3, so that the inner end of the rod can be moved out of the path of the lever arms 92, of the levers 82, to permit the matrix-block holder to be repeatedly rotated without feeding or shaving the matrix-block. The purpose of this is to produce duplicate castings of the same line of matrices. The
same result can also be obtained by providing a device for temporarily holding the pawl out of engagement with the ratchet-wheel 75. Such a device is illustrated in Figs. 19 and 20, and consists of a disk 99, adapted to be rotated through the medium of a finger-piece 100, and having an eccentrically arranged pin 101 which lies under the pawl 76, so that when the finger-piece is turned, the pin 101 will serve to lift the pawl 76 out of engagement with the ratchet-wheel 75. Therefore, the matrix-block holder can be repeatedly rotated without feeding or shaving the end of the matrix-block, and two or more castings from the same line of matrices can thus be obtained if occasion demands. The lever 98 can be locked by a latch 98*, for the purpose of holding the rod 95 when shifted out of the path of the lever-arms 92 of levers 82.
In Fig. 9 the matrix-block holder is shown in position when a type-high printing-bar is being cast from the impressed face of one of the matrix-blocks. The mold-disk or carrier 102 and the casting-pot 103 are indicated by dotted lines in Fig. 9'.
The rolling of the line of cameo or male type characters into the matrix material is very advantageous, but is not claimed in this specification, as it contitutes an element of some of the claims in my application for Letters Patent, Serial No. 488,800, hereinbefore alluded to.
The line-carrier in which the types are as sembled and justified, and the matrix-block holder make a half revolution in unison at each action of the machine in casting a print ing-bar, and the said carrier and holder are arrested when in the position shown in Fig. 9. While at rest the printing or type-bar is cast, and the line of types by which the line of matrices was produced is returned to and distributed in the type cases or channels of the magazine, and a new line of types is at the same time set up in that one of the line assembling or composing channels 43 opposite that from which the types are being removed. As these operations are all carried on concurrently, I will now describe the means for casting the type-bar or line of characters or words, and then explain the mechanism for accomplishing the other mechanical operations referred to.
The mold-disk 102 Fig. 21, is preferably provided, upon its periphery with four molds 104, of suitable dimensions for the production of the body portion of the type-bars. The mold-disk 102 is attached to a clutch-section 105, Figs. 3 and 29, loosely mounted on and adapted to slide lengthwise of a shaft 106. The shaft 106 is provided with a clutch-section 107 which rotates therewith, and between the clutch-sections 105 and 107 is arranged a coiled or other suitable spring 108. This spring constantly tends to force the clutchsection 105 and the mold-disk or carrier 102 toward the rotatable matriX-block-holder 67. The casting-pot 103 is arranged beneath the shaft 106, and is pivotally mounted, as at 109, and on the upper end of the pot is an arm 110 having a roller stud 111 entering an annular groove in the clutch-section 105, and susceptible of slight play back and forth between the walls of the groove. The arm 110 rises from that part of the top of the casting-pot which lies nearest the mold-disk or carrier, and upon the opposite side of the top of the said pot are mounted two anti-friction rollers 112, Fig. 1, between which engages a cam-disk 1l3,secured to a hub which is mounted on the shaft 106, Fig. 3. The cam 113 is so shaped that in its revolution the casting-pot will be vibrated toward and from the mold-disk or carrier. The vibration of the casting-pot opcrates the clutch-section 105 and causes it to engage or disengage the clutch-section 107, and the shifting movement of the clutch-section 105, causes the mold-disk or carrier 102 to move to or from the projecting smooth face of a matrix-block, so that during the casting of a printing-bar a tight closure is effected between a mold and the impressed or indented end of the matrix-block, while after the printing-bar has been cast, the mold-disk or carrier is moved slightly rearward, so that it can be rotated without obstruction to place another mold in position forcasting. When the casting-pot swings in a direction away from the matrix-block holder, or away from the mold-disk or carrier, the clutch-sections engage and the mold-disk or carrier makes a quarter revolution, but the clutch-sections disengage just prior to the completion of this quarter revolution. Therefore itis desirable to positively complete the quarter revolution of the mold disk or carrier, and to stop it at the proper point, so that a mold will register accurately with the mouth of the casting-pot, and with an impressed line of matrices in the matrix-block carried by the inatrix-block holder. To accomplish this the lugs 97 Figs. 21, on the matrix-block holder 67 are utilized. Each one of these lugs is adapted to enter a recess 114 at one end of each mold-box, so that as the matrix-block-holder 67 rotates in the direction of the arrow thereupon in Fig. 21,0ne of the lugs, 97, enters one of the recesses 11 4 and completes the quarter revolution of the mold-disk or carrier. At the same time the mold-disk or carrier is moved toward the matriX-block-holder 67 by the ac tion of arm 110 on the clutch-section 105, and one of the mold boxes passes beneatha rigid projection 115 Fig. 21, formed on a part of the main frame 1, whereby the mold-disk or carrier is stopped at the proper point for the casting operation and the discharge of a previously cast printing-bar. The rotation of the matriX-block-holder 67 is so timed and the operating mechanism hereinafter explained is such that the holder 67 stops the instant -the proper mold registers with the mouth of the casting-pot and with the line of matrices formed in the bright or lustrous shaved end or face of the matrix-block.
The casting-pot, as regards its internal construction, is substantially the same as in my patent and in my application, Serial No.
488,800, before mentioned.
The piston-rod, 116 Figs. 1 and 30, is pivotally connected, at its upper end, to a lever-arm, 117, pivotally mounted on a rigid bracket 118, extending from an upright shaft 119 fixed to the top of the casting-pot. The shaft 119 maybe solid or tubular, and is provided at its upper end with a screw-threaded portion 120, on which is adjustably mounted acollar 121 having an arm 122, constructed with a lug which enters the upper end of a coiled spring 123. The lower end of the spring bears against the lever 117 to depress thelatter and thus depress the piston in the casting-pot. The object of the adjustable collar .121 is to vary or regulate the tension of the spring according to the conditions required in the operation of the piston of the castingpot.' The lever arm 117 is adapted to be raised at proper intervals by a lifter or cam 125 which is keyed or otherwise secured to the shaft 106 so as to rotate therewith.
The casting-pot is supplied with heat by any suitable means, and is formed with an exit-channel or month 126, Fig. 25, through which the molten metal flows under the pressure of the piston in the usual manner. The exit-channel or month 126, communicates with the mouth of any one of the molds 104 when such mold is in the proper position for casting a printing-bar. While the casting mechanism is acting to cast a printing-bar, the line of types from which the preceding printing-bar has been cast is being removed from one of the channels 43 in the line-carrier, and returned to the type-cases or channels of the magazine. For this purpose the head 38, Fig. 11, is provided with curved exit-channels or chutes 127 the same as the inlet-channels or chutes 36, Figs. 9,10, and 11. The exit-channels or chutes 127 are the same as the corresponding channels or chutes in the line-carrier described and shown in my application for patent hereinbefore referred to, and such channels, or chutes 127, alternate in their arrangement with the channels or chutes 36, so that the types can be success ively received by a channel 127 and carried upward therethrough by a pin-wheel128, into engagement with the spiral-lift or screw 129. The first type which enters the channel 43 in the line-carrier will lie, when the series is complete, in that end of the exit-channel 127, which coincides with the left hand end of the channel 43, and for this reason it is desirable that the first plate introduced be a quad, or a mere blank, or aspacer.
In the upper part of the main frameis journaled a shaft 130, Fig. 1, on which is keyed a sleeve 129, Fig. 17, adapted to slide along but rotate with the shaft. The sleeve carries a disk or pin-wheel 128, rotatable in a plane parallel with the plane of rotation of the linecarrier, as shown in Fig. 9. A spring 139,
tating spiral-lift or screw 129.
Fig. 17, coiled on the shaft, acts to press the pin-wheel against the head 38 of the linecarrier, and from the face of the pin-wheel project two annular rows of pins 132 and 133, for a purpose hereinafter explained. The pin-wheel128 rotates continuously, and the pins 133 sweep through one of the exit-channels or chutes 127, and successively move the types therethrough into engagement with the lower end of the spiral-lift or screw 129. The pins 133 are arranged at regular intervals, and they engage the types successively, force them upward through one of the exit-channels or chutes 127, and into the lower end of a distributing chute 134, Fig. 31, where the lugs or shoulders of the types engage with the ro- Ihe spirallift or screw is journaled at its lower end in a bracket 135, Fig. 2, and at its upper end, in a fixed block 136, Fig. 4, forming a stationary part of the main frame.
As before stated, the composing-sticker feed-block 50, Fig. 11, is forced inward to com-' press the line of assembled types by the incline 53, Fig. 21, and is held in this position during a partial rotation of the line-carrier by engagement with the segmental track 54. At the end of the partial rotation of the line-carrier, after the line of type has impressed the bright orlustrous impression face of the matrix-block, and when the line-carrier is in the position indicated in Fig. 9, the composing-stick or feed-block is automatically forced lengthwise so as to move the line of type one step every time one of the types enters an exit-channel or chute 127, whereby the entire line of types can be discharged from the line-assembling or composing space 43. The lengthwise movement of the composing-stick or feed-bar is eifected through the medium of a vibratory arm 137, Figs. 1 and 3, secured intermediate its extremities in a rotatable post 138. The front end of the arm 137 is provided with a stud or roller-bearing 139, and the rear end is secured to a laterally projecting arm or rod 140, adapted to be acted upon by a face-cam 141, secured to a transverseshaft 142, which is driven as will hereinafter appear. The face-cam 141 is so constructed that the arm 140 can lie down in a recessed portion thereof, as shown in Fig. 3, into which position it is forced by the action of a spiral or other suitable spring 143 mounted on the rotatable post 138, and acting against the arm 137 with a tendency to force the front rollercarrying end of the arm 137 to the left, Fig. 3, and the rear end of the arm, which carries the arm or rod 140, to the right, Fig. 3 The parts are so timed that when the line-carrier rotates to impress the matrix-block and place the assembled line of types in position for distribution, the stud or roller-bearing 139 will bear against a laterally projecting pin 144 Fig. 13, on the outer end of the composingstick or feed-bar 50.
In Fig. 3 the arm 137, and the composingstick or feed-bar 50, are shown in the position 9 they occupy when all the types have been removed from the line-assembling or composing-chamber. In the operation of the parts, when the stud or roller-bearing 139 first engages the pin 144 of the composing-stick or feed-bar, the spring 143 forces the rear end of arm 137 to the right, Fig. 3, and the front end to the left, and as the types are successively removed by the pins 133 of the pin-wheel 128, the composing-stick or feed-bar is moved step by step to the left, Fig. 3, by the action of spring 143 and arm 137, so that as each type is removed by the pin-wheel, the remaining portion of the line of type is bodily shifted to place another type in coincidence with the exit-channel or chute 127. When the full line of type is assembled in the assembling or composing chamber of the linecarrier, the head 51 of the feed-bar 50 will lie at such distance toward the left, Fig. 11, past the exit-channel or chute 127, that the types can be successively removed by the pin-wheel without interference from the head 51. As before stated, in assembling a line I prefer to first introduce a blank or quad, because when the full line is assembled, such blank or quad will register with the channel or chute 127 and serveito prevent a type proper from being pushed back into the channel or chute until the proper time arrives. When all the types are removed from the-1ine-assembling or composing -channel in the manner described, and this channel is to be placed in position for the assemblage of another line of type,it is necessary to restore the composing block or feed-bar to its normal position,Fig. 11, so that its inner end is adapted to receive the types as in Fig. 16. \Vhen the arm 137 is in the position shown in Fig. 3, it is restored to normal position by face-cam 141, acting on the rear end of the arm, which causes the front end to swing to the right, thus placing spring 143 under increased tension to again move the composing-stick or feed-bar to the left, the same as before. The composing'stick or feed-bar is restored to normal position during the rotation of the line-carrier through the medium of an inclined track or cam 145, Figs. 3 and 11, which at its front extremity is formed with a beveled portion 146,-and an opening 147. The normal position of the composing-stick or feed-bar is shown in Fig. 11, in which the pin 144 lies against the beveled portion 146, while the roller 52 which may be mounted on the pin 144, bears against a suitable leaf or other spring 149, the arrangement being such that, although the pin 144 is adapted to bear against the beveled portion 146,the composing-stick or feed-bar can yield outwardly or to the right,Figs. 11 and 16, for the entrance of a type under pressure exerted by the pins 46 of the transfer-wheel 47.
In assembling a series of type in the assembling or composing-channel or space 43, the types are rapidly introduced, and therefore a rapid reciprocating motion is imparted to the composing-stick or feed-bar, it being moved outward or to the right, Figs. 11 and 16, by the pressure of the incoming type, and inward, or to the left, by the action of the spring 149, the inward motion being limited by the pin 144 striking the beveled portion 146 of the inclined track or cam 145.
When a line of type has been assembled in a line-assembling or composing-space or channel 43, the head 51 of the slide 52, will lie at or near that end of the line-assembling or composing-channel or space nearest the exitchannel or chute 127, Fig. 11. When the composing-stick or feed-bar is restored to its normal position, Fig. 11, it is necessary to restore the slide 52 to its normal position, so that the head of the slide will lie near the head 49 of the composing-stick or feed-bar and be in the proper position to. support the first type of the line. To accomplish this, the outer end of the slide 52 is provided with a recess or notch 150, adapted to be engaged by a pawl 151 pivoted to the composing-stick or feedblock 50, at 152, Fig. 14. The tail end of the pawl is acted on 'by a suitable spring 153, which tendsto throw the acting end of the pawl into engagement with the notch or recess 150. The angular portion 41, which constitutes the top or rear wall of a line-assembling or composing space 43 is extended to the right, as shown in Fig. 11, and the outer end of such extension is provided with a beveled projection 154, Fig. 14, which, when the composing-stick or feed-bar is moved to the limit of its outward motion, or to the right, acts upon the pawl 151 and disengages it from the notch or recess 150, thereby leaving the slide 52 free to be moved inward step by step as the types are successively introduced. When the line oftypes has been assembled, and the line-carrier has been rotated to impress the bright or lustrous face of the matrix-block, and the parts are in position to distribute the said line of types, the operation hereinbefore described, with reference to moving the composing-stick or feed-bar inwardly, or to the left, Fig. 11, takes place, and, therefore, when all the typeshave been pushed out of the line-assembling or composing-channel or space by the action of the composing-stick or feed-bar, the pawl 151 will have moved into the position required to engage the notch or recess 150. When this occurs it will be obvious that the outward movement of the composing-stick or feed-block, to restore it to its normal position, Figs. 11 andv 16, will automatically move the slide 52 outward to its normal position, and when the parts are in the proper position,and the outer beveled end of the pawl 151 is acted upon by the beveled projection 154, the pawl is freed from engagement with the notch or recess 150, and the slide can then be moved inward step by step, as before explained.
I will here explain that in my former application, Serial No. 488,800, I employ a single annular row of pins corresponding to the pins 133 Fig. 9, of the pin-wheel 128, but in to remove the pins 133 laterally from an eXitchannel or chute 127, and to accomplish this I provide a lever 155, Fig. 17, pivoted intermediate its ends, as at 156, and having one end adapted to be acted on by a earn 157, while the other end is adapted to act upon the hub of the pin-wheel 128, or a part of the sleeve 129 to push the sleeve in the direction of the arrow, Fig. 17, and thus shift the pin-wheel laterally the distance required to move the pins 133 out of the exit-channel or chute 127, whereupon the line-carrier can be rotated without obstruction. When the linecarrier has been rotated the desired extent, and the pins 133 are to be again moved into the exit-channel or chute 127, it is possible that one or more pins would enter this channel or chute at the improper time or point and prevent the proper engagement of a pin 133 with the end portion of one of the types. The pin-wheel is shifted back and forth at regular and uniform intervals, and, therefore, it is desirable, to prevent restoration of thepin-wheel into position to discharge the types from the line-assembling or composingchannel or space until the first pin of the pinwheel to act on a type is in the proper position, so that only one type can be between two pins, as otherwise the acting pin might strike the body of a type and by friction push out the type improperly, in consequence of which the spiral-lift or screw would not properly take or receive such type. To avoid this I provide the annular row of pins 132, Fig. 9, each of which is arranged directly opposite one of the pins 133, and is adapted to operate in connection with an irregularly shaped plate or latch 155 pivoted, as at 156 to a suitable supporting plate 157. The pin-wheel rotates continuously and its restoration after lateral shifting should take place when a pin 133 is in correct position to strike one end of a type. The acting-pin will be in correct position if the pin-wheel is restored when such pin lies anywhere between the lower end of plate or latch 155 and the periphery of the line-carrier. Therefore, the pin-wheel should be prevented from restoration to normal position until the pin 133 to act on a type is in the correct position referred to. If the pin 133, which is to act on the type, is in correct position, and the pin-wheel has been restored, the pins 132, act upon and lift the plate or latch 155 out of its path. While the pin-wheel is shifted laterally it cannot be restored so long as any one of the pins 132 lies opposite the plate or latch 155 because the pin 132 will bear against and move
