To all whom it may concern.-

Beit known that we, J osEPH C. FOWLER and J osEPH O. FOWL R, J r., citizens of the United States, residing at Baltimore city, State of Maryland, have invented new and useful Improvements in Type Casting and Setting Machines, of which the following is a specification.

Our invention relates to improvements in type casting and setting machines, and has for its object to provide an efficient machine of improved construction and operation adapted to cast single or independent types, assemble them in composed lines, justify such lines, and transfer them to a galley or printing-form.

The invention has also for its object to improve the construction, arrangement, and

mode of operation of the elements performing each of the stated operations.

To the end stated the invention consists in the machine hereinafter described and illustrated, in the several combinations of elements recited in the appended clauses of claim, in the mode of operation of the machine as an entirety, in the mode of operation of the several mechanisms embodied in the machine, and in the novel elements and arrangement of elements of the machine.

That which is regarded as new in respectof the elements and their arrangement, combination, and mode of operation will be set forth in the appended clauses of claim.

In the accompanying drawings We have illustrated a machine embodying our invention, in which drawings Figure 1 is a top plan view of the machine. Fig. 2 is an elevation of one end of the machine. Fig. 3 is an elevation of the other end of the machine. Fig. 4 is a sectional view taken on the line 1 4 of Fig. 1 and illustrating the line-ejecting mechanism and correlated parts.

Fig. 35 is a top plan view of the metal-pot. Fig. 36 is a fractional plan view illustrating i the construction of the matrix-well and the method of mounting the matrix-bars therein. 1 Fig. 37 is an enlarged detail showing part of i the finger-key mechanism, matrix-releasers, i and matrix-arresters. Fig. 38 is a plan view i of a preferred manner of arranging or bank- 1 ing the fingenkey mechanism.

The casting of the type is controlled by linger-key mechanism, which serves to release 3 and properly position a selected matrix character or characters of a selected matrix bar or bars in front of and close to an appropriate normally closed cell or cells of the mold, after which by depression of a proper key the matrices are alined, a metal-pot is caused to be brought to proper position, a mold-cell or mold-cells are opened, and type-metal is ejected from the pot into the mold cell or cells and against the matrix character or characters.

The matrix-bars which it is preferred to utilize in the machine are of substantially the character shown in Letters Patent of the United States, granted us the 22d day of July, 1902, No. 705,525. Each matrix-bar consists of a body 1, of metal or other suitable material, having formed in one face thereof a series of intaglio characters 2, arranged in a vertical line and having in lines coincident with said characters in the opposite face a series of recesses or sockets 8. It is contemplated, preferably, that a series of seventeen of such character matrix-bars shallbe employed, each of which will be provided with a series of fourteen characters in or on its face, providing a font, as it were, of two hundred and thirty-eight charactersa number adequate to permit the casting of all the characters in ordinary use in the art of printing and in addition thereto a blank bar 1 for casting spaces. It will be understood, however, that our invention is not limited to this character of matrix-bar nor the number thereof, this being preferential only. The series of matrix-bars are arranged in suitable ways 7, with which the matrix-well is provided, so that they may have distinct paths of movement in order that they may perfectly register in respect of a horizontal line passing through the mold with the several mold-cells.

'lhe linger-key mechanism of the present machine, the means by which the matrix-bars are released, and the means by which they are arrested and properly positioned with respect to the mold are generically the same as shown in the said Letters Patent, but differ therefrom in details of construction and arrangement of parts. Referring to Figs. 3, 37, and 38, where this mechanism is shown,

, the numeralsi indicate the key-levers, which are pivot-ally connected in vertical series to pivoted supports 5, and their free ends have operative engagement with appropriate matrix-arresters (3, of which there is one for each key of the clniracter-keys of the keyboard.

Each vertical series of keys is provided with characters corresponding in kind and relative arrangement with the series of characters of a given matrix-bar, and the cooperative relation of the kevmechanism, matrix-releasing devices, and matrix-arresters is such, as in the Letters Patent No. 705,525 before mentioned, that upon the depression of any character-key a corresponding matrix-arrester will be projected into the hereinafter-referred-to matrixwell 7 and arrest the fall of the released matrix, with its selected character corresponding to the depressed key in proper position in front of the mold. The numerals 8 designate the matrix-keepers and the numerals 9 the matrix-releasers. The matrix-keepers consist of a series of pivoted fingers corresponding in number to the number of matrices employed, including the space-matrix, and they engage suitable ledges,with which the matrixbars are provided, and normally support the latter in an elevated position in the matrixwell just in front of the mold, as shown in Fig. 10 of the drawings. Thematrixreleasers correspond in number to and cooperate with the matrix-keepers and consist of vertically-movable bars each appropriate to the keys of a vertical row of keys. A series of studs or pins 10 project laterally from the releaser-bars and rest on the key-levm's, as clearly shown in Fig. 37. The upper endsof these releaser-bars are in position when lifted by the actuation of a cooperative key to engage and trip the matrix-keepers, as best shown in Figs. 9 and 10 of the drawings.

in use a single individual type may be cast in one cycle of operation of the machine, or where a sequence of type which it is desired to cast may be found on the keyboard running in any direction from left to right as many individual types may be cast as may be within the sequence. This being understood, the machine will be hereinafter described without reference to whether a single individual type or sequence of individual types are selected and cast during a given cycle of operation of the machine.

The matrices are selectively released by actuating the appropriate key of the finger-key mechanism, which lifts a correspomling matrix-releaser to trip the proper keepe and release the matrix-bar. This operation is clearly shown in Fig. 9. The key mechanism sinmltaneously with the performance of its matrix-releasing function operates to project a matrix-arrester into the matrix-well to ar- '12, formed in the machine-frame commumj eating with the matrix-well and correspond.

in. number and alinement with the severalmatrix-bars. These alining-blades are connected, respectively, by relatively stiff springs 13 toa rock-shaft 14, (see Figs.- 9 and- 10,) the idea being that on the rotation of said rockshaft the alining-blades will be forced into the properrecesses or sockets 8 of a released matrix, as shown particularlyin Fig. 9 of the drawings, and thosealining-blades corresponding to-matrix-ba'rs which have not been released will enter supplemental recesses or.

sockets 3, provided therefor. as shown in Fig. 10. The alining-blades not only serve to accurately bring the selected matrix character in front of the appropriate mold cell and maintain it there during the casting operation, but also to force the matrix-bar closely against the face of the mold, so thatthe moldcell is closed with nicety.

The spring or yielding connection of the alining-blades with the rock-shaft is of value in that thereby individuality in the action of the alining-blades to compensate for any pos sible irregularity is affordedas, for instance, should it ever occur that the sockets-or recesses 3 of any of the matrix-bars be slightly deeper by reason of wear or otherwise than the sockets of other matrix-bars the alin-- ing-blade corresponding thereto will have a throw sufiicient to push said bar closely against the face of the-mold, while the springs of the alining-b'lades of other matrices which do not need so great a throw will yield. Again, by reasonof this yielding connection of the alining-blades with the actuating rockshaft it is possible that the shaft may to in sure a close fit of the matrix against the mold be rotated a maximum degree-a little more than necessary ordinarily to cause the alining-blades to perform their proper functions. In this event by reason of the yielding spring connection the alining-blades will yield to compensate for the overdegree of' rotation of .the rock-shaft. Thus variations and chiliculties which might occur by reason of wear if the alining-blades were thrown by an unyielding fixed positive movement are obviated.

: The alining-bladesareintended to come into operation, as is obvious, when the matrix-bars have been released, have fallen, and are properly positioned against the mold. They are in the illustrated example of our invention bestshown-in Figs. 1 and 3. When, as here-- inafter described, the space-key or startingkey is operated, the camshaft 19 is placed in .clutch engagement with the main or driving shaft of the machine. whereupon the cam-race 18 causes the arm 17 to retreat. The pullingspring 20 causes the finger 15 to follow the retreating movement of said armgand thus the alming-blades are caused to enter the recesses or sockets 3 or 3 of the matrix-bars. When the arm 17 under the action of the cam 18 has nearly finished its retreating stroke, the

abutment 17 thereof, which is shown as adjustable, engages the finger 15 and acting positively thereagainst forcefully pushes the alining-blades into the sockets or recesses of the matrix-bars referred to, causing the latter to be pushed hard against the face of the mold to accurately close the mold-cells thereof.

When it is desired to cast a space, the spacekey 21 (see Fig. 29) is actuated, releasing the space-matrix bar, which falls in the well until arrested by the engagement of a pin 22, projecting laterally therefrom, with a part of the machine-frame 23, that constitutes a suitable stop. (See Figs. 11 and 12.)

In the preferred arrangement shown the space-matrix and the space-key are at the extreme right, and consequently terminate any sequence possible for a single'cycle of oper matrix-bars, including the spacer-matrix bar- This mold is preferably made up of plates 24 and 24: and an intermediate series of blocks 24: (see Fig. 15) bolted togethera convenient manner of manufacturing.

The spaces 8, the preferred form of which is illustrated in Fig. 19 of the drawings, must obviously be of less height than the character types. To effect this, it is arranged that the mold-cell for casting spaces shall be shorterthan those in which the type characters are cast. Thls 1s accomplished in the manner shown in Figs. 15 and 16 of the drawings by means of a sliding mold-section 25, which has a projecting lip 25, that constitutes an end wall of the space-casting cell whenthe parts are in casting position, and when a cast is made in order to permit the ejection of the space the sliding section is moved in a reverse direction to open the cell. Said sliding section is operated by means of a pin 26,

depending therefrom andfitting into a recess 3 in the machine-frame and. which when the mold is moved to e ecting position abuts against one wall of the recess 27, Fig. 25, and

stops the movement of the sliding section, whereby the space-cell of the mold is opened. WVhen the mold is returned to casting position said pin 26 abuts against the opposite wall of said recess, and the lip closes the end of the cell and constitutes an end wall thereof, and in this way the length of the castingspace of the cell is shorter than the castingspaee of the type-character cells of the mold.

The mold may be provided with a suitable cooling-chamber 2 t to prevent heating thereof, and thus facilitate or expedite the hardening of the type cast therein.

A series of gates 28, one of which is shown in perspective in Fig. 18, are arranged to open and close the entrance ends of the mold-cells. These gates, as best shown in Figs. 9 and 10, movably fit against the face of the superstructure of the mold and are normally maintained in position to close the mold-cells against the entrance of metal from the metal-pot by means of springs 29 and confining-strips 30. The gates are provided with openings 28, which are caused to register with the mold-cells when a cast is to be made and with arms 28", that overhang and normally rest on the matriX-bars.

The metal-pot 32, which is of the tilting type and the preferred details of construction of which will be hereinafter described. is suitably pivoted, as shown in Fig. 6, and is provided with an arm 33, engaging a cam 34, arranged on the camshaftofthe machine, whereby it is caused at the proper time to be tilted to bring its discharge-orifice into register with the mold-cells. The pot is provided with a bracket 35, in which are arranged a series of gate-openers 36, one for each gate, consisting of spindles 37, yieldingl y fitted in said bracket by means of suitable springs 38. The operative arrangement is such that if no key of the key mechanism is actuated and no matrixbar is released then no gate will be opened and no cast taken, because the arms 28" thereof rest upon the unreleased matrix-bars, which prevent operation thereof, and the mold-cells therefore remain closed against the entrance of metal, the gate-openers yielding against the springs 38 in such event. hen, however, a matrix-bar is released, it drops from beneath the arm 28 of the corresponding gate, and the latter is then caused to be mo ed by the appropriate gate-opener to bring the opening therein into register with the appropriate moldcell, so that the metal may enter such cell. The remaining gates, however, which they govern are maintained in normal position to keep closed the cells which they govern by means of the unreleased matrixbars, and no metal is allowed to enter the mold cells closed by such gates.

It is intended that the metal in the pot shall be kept in a molten state by means of a suitable heater arranged below the pot, well known and not shown herein. To secure the greatest benefit of the heat thus supplied upon all parts of the pot, a surroundingjackctiit) is provided, in the space between which and the body of the pot the heat readily ascends and by which it is confined to the area of the pot. In order to supply the heat in close proximity to the discharge-orifice of the metal-pot, where it is needed by the comparative attenuation of the body of metal at that point, it is conducted to a chamber 10, provided near the top of the pot adjacent to and behind and in front of the dis charge-orifice, and then passes off through a. suitable flue 4C1. Openings 412 are provided for the escape of the heat, which passes up through the space between the metal-pot and the surrounding jacket, so that a circulation is maintained.

The metal-pot, as best shown in Fig. 3:), is provided with two compartments, one, T3, for containing type-metal and the other, 453", for space-metal, the latter metal being of a softer nature in order that the space, preferably of the shape shown in Fig. 19, shall be compressible to secure thejustification hereinafter described. The larger type-metal compartment 43 of the pet has a channel 16 leading to a discharge-orifice L7, common to all the cells of the mold except the space-casting cell, and the other compartment, -13, has an independent channel a6 leading to an individual discharge-orifice a7. Each compartment is provided with a suitable pump 1 as best seen in Figs. 5 and 6, working in a cylinder within the pot and with which the channels to the discharge-orilices communicate. The pumps are actuated by the rocking levers51 51, working against suitable cams and 52 on the cam-shaft 19. The return stroke is accom plished in two moves, the first being a slight n'iovement by reason of a slight face of the cam, which imparts but a slight suction, so that the metal is withdrawn in a gentle manner, whereby the liability of sucking out metal from the body of the type is avoided, and then by reason of a more acute face of the cam the metal is forcefully and rapidly withdrawn into the pot to avoid danger of becoming cooled in the channel.

The mold is carried by a slide 5?), (see Fig. 25,) arranged in a guideway provided in the machine-frame, and connected with this slide is a link 5*, (see Fig. 13,) the other end of which is connected to a lever-arm 5st, working in a cam-race formed in a. barrel 51", mounted on the cam-shaft, as best shown in Fig. 1. hen in the casting position, the relative arrangement of the mold, the slide by which it is carried, the link, and the arm, are shown in Figs. 11 and 1?) of the drawings. At the proper time when a cast has been made the slide 52-), with the mold and its appurtenances, is shifted to the ejecting position, (shown in Figs. 12 and 14,) where the relative position of the parts is clearlyillustrated,allowing ample opportunity for the cast type to cool.

The operation of mechanism by whichthe metal-pot is tilted, the mold-gates opened,

the metal ejected from the pot into the mold cells, the shifting of the mold and appurtenances, and the mechanism by which the subsequent operations of the machine are effected is started either by action of the startingkey or by the space-key 21, the tails of both of'-which keys engage arms 56, carried by a rock-shaft 57, (see Fig. 29,) whereby said shaft is rocked, releasing a trip-arm 58, connected thereto, from engagement with a weighted tumbler 59, mounted on a short shaft and which by the influence of gravity partially rotates said shaft. A mutilated groove-drum 61, Fig. 30, is carried by the shaft 60 in proper relation to continuousgroove drum 62 on a short shaft 63, which shaft 63 is constantly driven from the main shaft A by means of a gear 6 1 on the main shaft meshingwith the teeth of a clutch-wheel or element 65 on the counter-shaft, which carries a sprocket-wheel 66, connectedby a chain 66 with a sprocket-wheel on the short-shaft 63; A cam 67,,Fig. 31, on the shaft 60 is thus caused 'to operate a crank-arm 67 to withdraw the bolt 68, Fig. 3 1, and allow a spring-impelled coupler 69 to enter one of the sockets 70 in the clutch member 65, mounted on the cam-shaft 19, whereby said countershaft 19 is caused to operate to effect one cycle of operations of the machine, whereupon the mutilated or inactive part of the drum 61 comes opposite the drum 62 and rotavention is not'restricted thereto. 1

During the shifting of the mold to the eject ing position the gates are lifted by means of a rail 73, provided on a plate 7-1, hereinafter described, on which rollers carried by said gates travel, as shown in detail in Fig. 17. v

In this way the openings 28 in the gates are brought into register with cleaning-channels '75 in the mold, as shown in Fig. 5 of the drawings. When' the mold and its appurtenant gates are transferred to the ejecting position, the mold-cells are in register with a series of guide-openings76 in the plate 74 and the openings 28 in the gates are in line w1tli another series of guide-openings 77 1n said plate, which is shown in detail in Fig. 17.-

An ejector E (shown in detail in Fig. 2 1 of the drawings) is arrangedto reciprocate on the machine-frame by means of a cam 78 on the cam-shaft in the relative position shown in erably, though not necessarily, through a die 81, Figs. 5 and 20, having openings 82 of the configuration and dimensions of the body of the type, and in the passage through which any burs, if by any possibility such may have been formed in the casting of the type, are removed. This die is not essential to the op'' eration of the'machine; but to compensate for possible failure of employees to keep .up the adjustment of parts and to keep the machine perfectly clean it is considered desirable to provide it. The cleaning-fingers on the forward movement of the ejector enter the" openings in the gates, as before eXplained,-'

and project any particles of metal that may be contained therein 'intoand through the passages therefor provided in the mold, as best shown in Fig. 5 of the drawings.

The type ejected from the mold, whether a single individual type or'a series of individual type, depending upon whether the operator can cast a'sequence of type at onecycle of' operation of themachine, are allowed toremain in the type-race, and the mold and its appurtenances are returned to the casting position by means of the 'link 5 1 and arm'54, connected with the slide 53, that carries the the mold,'. said arm passing upon an appropriate surface'of the barrel-cam 54 On the return movement of the mold the mold-closing gates are restored to normal position by means of the inclined part of the rail 7 3, arranged on the plate74, before referred to, In the meantime the matrix bar or bars and the matrix-bar arrester or arresters previously put into operation will have been returned to initial or normal position by ashoe 83, arranged to swing on an axis 84: and operated by a high-pitch cam 85, mounted on the cam-shaft, immediately preceding which return of the matrix bar or bars and arrester or arresters the alining blade or blades 9 11 will have been withdrawn from engage-- ment with thematrix-bars by the rotation of the rock-shaft 14, caused by the action of an abutment 17 of the arm 17in the forward movement of said arm. The elements are now in proper relative position therefor, and

another cast, either of a single individual type orsequence of individual types, is now made, as before, the mold shifted to ejecting position, as before, and the type ejected there from and the openings in the gates cleaned, as before.

(see Figs. 25 and 27) by a composing-finger The type or sequence of type left in the l type-race by the previous operation of the j machine is now pushed along the type-race 1 into the composing and justifying box 100 1 8t), sup 'iorted by and in the van of the mold. This composing-finger is slidably connected with the mold and normally held to its posi 5 tion of work by a spring 87. On the return of the mold to casting position, however, this composing-finger is shifted to a path clear of the type-race by means of an extension 88 of the ejector, which engages the composingfingerand moves it to the position shown in i Fig. 27, whereupon a spring-actuated bolt 89 is projected from its housing and stands in 1 front of that part of the mold to which the composing-finger is connected, thus holding the composing-finger out of the way on the return movement of the mold. When the l mold reaches casting position again,the springbolt engages a nose 90, that forces the bolt 1 89within its housing, and the finger is then i drawn into operative position by means of its spring 87.

. The described operations are repeated un- 1 til approximately a sufficient number of type or type and spaces to form a justified line have been cast, whereupon the operator is advised of this fact by an indicator 91, moving along a scale 92, preferably arranged on the keyboard-casing. The operator will then in the subsequent operation or operations of 1 casting depress just so many keys to cast just so many type as will approximate a justified line, the intention being that the line shall be slightly overset and justified by compression of the spaces.

In passing along the type-race the type and spaces are accurately guided by a yielding depressible track 93, arranged in a suitable recess of the body of the type-race and projecting above the surface thereof, as best shown in Fig. 20. The type when ejected from the mold ride over this track until guide-recesses 93, with which they are provided, take over the track, along which they move in accurate alinement to the composing and justifying box or chamber 100. This composing and justifying box is formed of an extension of the type-race, which constitutes the bottom thereof, and movable rear and end walls, the line-ejector hereinafter referred to constituting the movable rear wall thereof and the extension 88 of the type-ejector and the abutment 94 constituting movable end walls there of. The box has an open front to permit of the passage of the line therefrom.

The justification of the composed line is effectedin the following manner: A movable abutment 94 is provided, the initial position of which is shown in 11 and 13 and against which the first type cast is moved by the composing-finger 86. This abutmentis g arranged to move on a guide-rod 95 and re- 1 to the galley or printiug-form i101.

codes under the action of the composing-linger and intervening type progressively as the latter accumulate until the requisite munber of type to form a justified line has been assembled, at which time a bar 91", connet'sted to said abutment rides off the tail end of a roeki ug arm 97, (see detail, Fig. 23,) carried by a lineejector 98, permitting its other end to drop into the path of said line-ejector-actuating mechanism 99, (see Fig. 1,) by which it is engaged, and the line-ejector ad 'ances to push the line. from the composing and justifying box loo The lineejector is actuated when the tail of the rocking arm drops, as referred to, by a plunger 102, operated by a cam 103, as shown in detail in Fig. 1. This plunger reciprocates at each rotation of the counter-shaft, but becomes active to operate the line-ejector only when the end of the rocking-arm 97 drops into its path of reciprocation. The movable abutment is provided with spring-controlled ratchet 10 t, (see Fig. 21,) which engages av rack 105 to hold the abutment step by step in the progressive position to which it is advanced by the successive type or spaces com- (,)n the completion of a line the ratchet is disengaged from the rack by a releaser-cam 106 and is held so out of engagement by the spring 1117. \Vhen the line has been ejected, the abutment is returned to initial position by a spring 106, mounted on the rod on which the abutment moves. Prior to the ejection of the. line, however, the justification of the composed line is effected by means of a. toggle-line eompresser 109, actuated by an arm '1 10, engaging a suitable cam 111, carried by the camshaft, the operative parts of this cam and that which controls the line ejector actuating mechanism being so disposed and timed that the justification by compression takes place in advance of the transfer of the line from the justifying-box to the galley. The abutment 112 for the finishing end of the line, and which constitutes that side of the justification-box in the example of our invention as illustrated in the drawings, consists of that extension 8b of the type-ejector which operates to move the composing-finger out of the way, as before explained. This extension passes across the composing-surface and rests there by reason of the formation of the cam by which it is operated sufficiently long to enable the justification to take place. As the composed and justified lines are moved into the galley 1111. which is of any suitable or usual kind, sustained by a coul'iterweight 1.1 1, a line-pusher 115, worked by a cam 116, descendsand pushes the line accurately to place in the galley and causes the galley to fall a distance equal to the height of a line of type, where it is retained by a suitable dog 117, el'igaging a rack l 18.
