To 1/,ZZ whom, it may concern:

Be itknown that 1,' OTTMAR MEEGENTHA- LER, acitizen of' theUnited States, residing at Baltimorein the State of Maryland, have invented certain new and useful Improvementsin Linotype-Machines, of which the foldividual characters are through the instrumentalityl of escapement Ymechanism controlled by finger-keys delivered from a magazine, composed or, assembled in line, justified, and presented to the face of the mold,l which is then filled with molten type-metal to produce the required bar or linotype, having on its-face an impression of the assembled matrices." After these operations the matrices are returned through a distributing mechanismtothe magazine from which they started.

The present machine is of the same general character as those represented in numerous Letters Patent heretofore granted to mesuch, for example, as Lette-rs Patent No.l 317,828, dated May 12, 1885, and No. 378,798, dated February 28, 1888,:but more particu-J larly to that form of machine represented-in the Letters Patent granted to me, Nos. 436,531 and 436,532, dated September 16, 1890.

The present invention is designed to simplify and to reduce the cost of manufacture of the machine; and to this end it consists in various improvements' in construction and oper'atiom'which are hereinafter to be described in the specification and finally pointed out in the claims.

Referring now to the drawings, Figure 1 is a front view of my limproved linotype-machine, showing such parts 'of the machine as are at the front thereof. Theportio'ns of the machine at the back have been omitted from this View in order to avoid confusion in the proper. I lthe 'assembling mechanism and of the key- Serial No. 680,964. (No model.)

My improved machine is intended to han- Fig. 25 is.

dle matrices such as are shown in Fig. 33 in connection with the space bars or wedges such as are shown in Fig. 32. The matrices Y, properly assorted, are contained in the elevated magazine B, having a series of channels through which the matrices descend to the eseapement devices at the bottom thereof which are actuated through the escapementrods E, operated in turn by the finger-keys D. Similarly the space-bands Z are contained in the space-band box K and are released therefrom by an escapement device hereinafter to be described, operated from a suitable iingerkey. The discharged matrices, which are released in the desired order and one at a time, descend through the guidingchannels G, formed in the assembling-plate, and are re ceived on the upper surface of the traveling belt H, by which they are delivered successively into and assembled in line in the slotted assembling-box I. The space-bars Z are released one at a time when desired in such manner that they descend into the assembling-box to be added to the line of matrices. As the line of matrices and space-bars is assembled it is held in compact form by the yielding resistant J, which is moved to the left step by step as the matrices and space-bars are delivered into the assembling-box by means of the rotating assembling star or cam H13. When the line is completed, the operator shifts the line manually to the left through the guide M until it is introduced and contained within the elevator N. The elevator N is then man ually released by the operator and descends by its own weight until the line of matrices and space-bars is brought into proper position in front of the mold. This descent of the elevator through mechanism hereinafter to be described automatically starts the further operation ofthe machine which effectsthe proper movements of the pot S and mold O and the justification of the line through thejustifyingpiece Q,the proper locking and clamping of the line longitudinally through the sliding jaw R, and the ejection by means of the pump-plunger S8 of the molten metal from the pot Sinto the mold and against the faces of t-he matrices in front thereof. The parts are then released from their casting positions and the mold turned through an angle of two hundred and seventy degrees in such manner that the base of the slug is trimmed by reason of its passage against'and by a stationary knife S21. When the mold comes to rest again,the ejector starts forward through the mold and forces the linotype out of the mold a distance of about an eighth of an inch, when the knife S22 starts to descend and trims one of the front edges of the slug or linotype throughout its entire length. After this trimming of one edge of the linotype or slugthe ejector acts further to force the linotypc or slug completely from the mold and into the knife-box Si, which contains the knife for trimming the otheredge of the slug or linotypc. In this position the slug is engaged and forced longitudinally by IOO IIO

means of a slugshifter SL32 through the knifebox and passes the knife contained therein,

which trims the other front edge of the linotype or slug throughout its entire length. The linotype or slug is then'dropped into position to be engaged by a vibrating finger S49, which assembles it with the lLinotypes previously cast in a chase or form S48A in suitable order to be printed from. During this operation of the ejection' and trimming of the slug the elevator N has ascended to the upper portion of the machine, carrying withit the line of matrices-and space-bars until they register exactly with the distributing-box'. The line-shifter W then moves in to the right, carrying the line of matrices and space-bars into the distributing-box, where the spacebars are separated from the matrices by means hereinafter to be described and returned to the space-band box or magazine. The shifter WV continues to move the line of matrices toward the distributing mechanism X, where they are engaged one by `one and returned to their therewith has been stopped automatically byY means hereinafter to be described. It will be seen that, as in my previous patents referred to, the matrices and space-bands are returned to their proper magazines by a path different from that which they pursued during the course of assemblage, or, in other words, that I still employ herein what is termed in the art as the circulating system. This feature enables the operator to start in upon the composition of a secondline immediately after he has transferred the first line to the elevator and releases the elevator, so that it may descend to its operative position, as the further operations of justifying, casting, ejecting, trimming, and distributing are entirely automatic. l t

Matrices-The matrices employed in the machine are preferably identical in construc-A tion with those described in my Letters Patent Nos. 436,531and 436,532, previously referred to. As shown in Fig. 33, each matrix Y consists of a flat rectangular plate of brass,

steel, or likematerial provided in one edge with the intaglio letter or matrix proper and recessed in its two vertical edges to produce the four shoulders AY. The matrixis also notched centrally in its upper edge and provided with sustaining-teeth Y2, the number and arrangement of which differA on matrices bearing different characters, so that they may be employed as a means of distinguishing betweenand distributing the matrices in the manner set out at length in Letters Patent No. 347,629, granted to me onlthe 17th daypf August, 1886, as well as in numerous other Letters Patent granted to me.

Space-bars.-The space-bars or justifying devices are of the same character as those described in numerous Letters Patent hereferred to.

tofore granted to me-such, for example, as

the Letters Patent previously. referred to, Nos. 436,531 and 436,532.' As shown in Fig. 32, each bar consists of a long wedge Z, carrying on one side a second and shorter wedge Z, which is provided at the upper end with ever, and preferably employ herein its construction with a Vertical post or pillar A', on which the keyboard mechanism, the Yassembling mechanism, the matrix-magazine, and the distributing mechanism may be firmly placed and secured. This is or may beeffected by the employment of collars A2 A2, which may be slipped over thepost or column A and secured thereto in the desired position by means of set-screws A3 A3. This form of construction and arrangement affords me a simple and perfectly practicable method of adjustment and attachment, insuring the independent and exact adjustment of the parts in their desired positions.

Thematrt`x-magaztne.-In the present form of machine the matrix receptacle or magazine B is employed in vertical position instead of in inclined position, as in the Letters Patent Nos. 436,531 and 436,532, previously re- This magazine B consists, essentially, of a front plate B2 and a rearplate B', one overlying the other and divided between theirapprox'imate faces into a large number of longitudinal grooves or 'receptacles for the matrices by means of the intermediate partitions BS. (See Fig. 29.) It will be observed that under this arrangement the matrices are held end to end .in rows or lines in their respective compartments and permitted to slide freely downward between the plates, those in one line being kept out of contact with the y'adjacent lines.

The construction of the magazine-channels may be similar to that illustrated and shown in my Letters Patent No. 436,532, it being noted that the magazine as a whole is flared or made in fan shape, the upper ends of the magazine-channels being separated, so as to facilitate the proper distribution of the matrices. From the upper part of the magazine to the lower part the channels gradually converge, so. that at the lower extremities the series of channels lie closely together and in IOO IIO

close proximity to the receiving-channels G;

This convergence of the channels may be secured by tapering the intermedi-ate partitionplates B8 or in any other suitable manner.

At the lower part of themagazine the front plate B2 is provided with doors or inlets B3,

hinged upon the transverse rod B5 and ordif narilyretained in closed position by means of the pivoted springs B1. (See Fig. 2.) By turning the several springs B4 about their pivots the doors orinlets B3 may be opened, so as to permit access to the magazine-channels. It will be noticed that the location of the doors B3 at the bottom of the plate B2 gives a ready and convenient access to the magazine-channels at the front of the machine and in close proximity to the operator. The rear plate B is provided with lugs B7, Fig. 29, which are adapted to pass over and engage the horizontal rod B0, attached to the main frame of the machine and which sustains the magazine in pendent position, so that it may abut at its lower end against a suitable portion of the frame of the machine and remain in proper adjustment with the assembling-plate hereinafter to be described. It will be seen that all that is necessary to secure a change of fontis to lift the magazine from its position by disengaging the lugs B7 from the rod B6 and to substitute therefor another and similar magazine containing the desired characters.

The upper portion or mouth of the magazine which receives the matrices from the distributing mechanism is constructed in the following manner: Pivoted at B4G to the plate B2 of the magazine are the two upright plates B10 B10, slotted vertically, as clearly shown in Figs. 29, 30, and 3l, to receive the reduced ends of the partition-plates B0. These ends of the partition-plates B0 pass through the vertical slots in the upright plates B10 B10 and are secured therein by means of a rod B11, which passes between the two uprights B10 B10 and through corresponding holes formed in the reduced ends of the partition-plates- This method of adjustment is one of great simplicity and permits of the ready change of a partition-plate simply by the withdrawal of the rod B11. These partition-plates B0 are held against vertical displacement by the longitudinal bearing-bar B11 under which they lie. The portion B12 of the partition-plate which is in direct proximity with the mouth of the magazine proper is made corrugated in form, as clearly shown in Figs. 29, 30, and 3l. This corrugation is made use of to adjust the passages to the exact width of the matrix, so as to prevent their turning, as the upper ends of the channels of the magazine B, as before stated, are made much wider than is necessary to hold and retain the matrix. The other end of the partition-plate B0 rests on and within the lerfs ot' a serrated longitudinal plate B13, which is also attached to the upper plate of the magazine. These kerfs or serrations in the plate B13 permit a certain amount of resilient lateral movement to the partition-plates B0, which is availed of to stop the distributing mechanism when a matrix is misplaced in the manner hereinafter to be described. It will be seen that the pivoting of the magazine-mouths at B40 to the magazine proper permits them to be swung out and gives a ready access thereto.

The magazine as a whole is light and simple in construction and dispenses with the heavy and cumbrons metal castings sometimes employed in machines of this class.

Matrix 'delivering mccham'sm.-At the lower end of the magazine I provide each channel with an escapement which allows the discharge of a single matrix at a time. This escapement (which is clearly shown in Fig. 5) is practically identical with that shown and described in my Letters Patent Nos. 436,531 and 436,532, previously referred to. It consists of a centrally-pivoted lever or plate E2, pivoted to the magazine and provided at its opposite ends with the horizontal pins E4 E1, which play alternately into the magazine, so that when the lower pin E4 is retracted to release the lowermost matrix in the line the upper pin E'1 will advance into the channel to arrest the downward movement of the next matrix. A spring E3 acts constantly on the rear end of the escapementlever E2 and assists the inward movement of the upper pin E4 when the latter is permitted to act through the operation of the mechanism now to be described. The rear portion of the escapelnent lever or plate E2 is formed with a notch, which engages a similar notch in the upper end of the escapement-rod E. These escapement-rods E are located at the rear of the assembling-plate and are suitably guided at their upper portions in a rack or recessed plate C2, attached to the assemblerplate, hereinafter to be described. At their lower ends these bars E pass into a rack or guide D3, attached to the keyboard, and rest therein upon the bars or plates D2, which in turn are actuated by the finger-keys D, pivoted at D. Springs E/ E are attached to the guide or rack D3 and to the escapement-rods E in such manner as to hold the escapementrods in a depressed position and are of such strength as to overcome the tendency of the springs E3 to turn the escapement plates or levers E2 and to withdraw the lower pins E1 from the magazine-channels. Vhen, however, the finger-key D is operated, the escapement-rod E is raised against the pressure of the springs E', and the spring E3 is thus permitted to operate the escapement-lever E2 and withdraw the lower pin E1 in such manner as to permit the release of a single matrix in the manner well known and understood in the art. When the finger-key D is released, the spring E restores the escapement-rod E to its original position and overcomes the pressure of the spring E3, thereby Withdrawing the upper pin E1 and reinserting the lower pin E4in the magazine-channel, when the next matrix is in position to be released in the same manner. It will be understood that the escapement-rod E may be directly connected to the finger-key D and the plate D2 dispensed with, if desired.

It will be observed that in the present machine I dispense entirely with the automatic delivery and escapement devices, as illusmachine are of the same general character as those described and yclaimed in my Letters Patent Nos. 436,531 and 436,532, previously referred to, but dier therefrom in various minor features and will be hereinafter point-,-

ed out. On being discharged from the magazine the matrices descend vertically to the vertical channels or guides formed within the entrance-plate. These channels or guides G are formed between the plates G4 G4 by partition -plates G3, which are attached to the rear plate G4 in the manner clearly shown in Figs.` 5 and 8. Each partition-plate ,G3 is provided with two or more projecting lugs, which pass through corresponding recesses in the rear plate G4 and are there retained by means of the rods G5, which pass through holes in the lugs of the partition-plates G2, firmly retaining them in position. This form of construction affords a simple and easy means of substituting or changing the partition-plates G2. The front plate G4 at its lower edge is hinged at Gwinthe manner clearly indicated in Figsl and 2,so as to permit access to the guides or channels G. The lower ends of the ribs or partitions Gsare deflected slightly to the left, as in the former patents referred to, and terminate near the inclined belt H, in order that the matrices may be presented flatwise and with proper end foremost upon the belt. The upper ends of the escapement-rods E, as before stated, are contained within and guided by the rack or guide G2. This rack G2is attached to the piece or bar G', which is connected to the back plate G1, Figs. 2 and 5. Attached to the bar G' is the spring G1,which is also connected to the frame of the machine, Fig. 14. The piece G' is provided with elongated screw-holes, through which the supporting-screws G6 pass into the frame of the machine, Fig. 2. It will be seen that the tendency of the spring G7 will be to force the entrance-plates and channels G constantly to the left, sliding them upon the screws G6 until the piece G abuts against the adjustingscrew G8. (See Fig. 2.) In this manner I am enabled to secure an exact and constant registration between the assembling-channels `and the mouths of the magazine and also through the attached rackor guide G2 of the escapement-rods E and the escapement-levers E2.

The belt H is carried around the pulleys H', H7, and H8. Instead'of employing the bevel and other gearing of my prior patents motion is directly imparted to the upper pulley H' from the pulley H6 on .the intermediate power-shaft H25 through the medium of belt H5 and pulley H4, which is fast on the rear end of shaft H3. (See Figs. 2, 14, and

assembling.

25.) The pulley H is attached to and turns with the shaft H3 by means of the handclutch H2, which is within easy reach of the operator and whereby he is enabled to stop or start the belt H at will, Figs. 2 and 25. It will be noticed that at the lower end of the belt H. instead of one pulley I employ two pulleys H7 and H11. These two pulleys are so located as to give the belt an angular turn at its lower end and to insure the delivery of the matrix in an approximately vertical position, thereby enabling me to dispense with the plate, which is shown as straddling the lower end of the belt in my Letters Patent No.` 436,532. v

At the lower end-of the assembling-belt H and directly in front of the assembling-box is the assembling star or cam H12, which serves to force the descending matrices forward one after another into the assembling-block,wher e they stand in vertical position side by side, as shown in Fig. 2. A guide-piece H14, above the assembling-star H13 and near the lower end of the assembling-belt H, serves the double purpose of checking the space-bands in their fall and of preventing the matrices from falling off the belt H and insures their proper delivery in front of the assembling-star H13. Motion is imparted to the assembling-star H13 from the belt-pulley Hs in the manner shown in Figs. 5 and 7. The journal of the pulley H8 is continued, rearwardly through the supporting-plate H26 and carries fast on its end the pinion H9,'which gears into a pinion H111, also journaled inthe said plate H26. This pinion H10 gears in turn into a third pinion H11, loose on the shaft, which carries the assembling-star H13, but which ordinarily causes the rotation of the said shaft and star by reason of the spring connection H12, fast on said shaft. This spring connection H12, however, permits the stoppage of the assembling-star H11'1 in case a matrix or space-band should bef come jammed or wedged in front of it, and thereby prevents the breakage of the parts. In front of the assembling-star H13 and of the pulleys H7 and H8 a glass plate H15 is provided, which is held in a frame H17, (see Figs. 2 and 5,) pivoted at H18 in such manner vthat 'the plate H15 may be swung to the right, so

as.to permit access to the parts within. rlhe spring H16 holds the plate firmly when it is closed, and a set-screw H11 limits its inward motion.

The space bands or bars are suspended in their magazine K, are delivered one at a time therefrom, and descend through the channel or conductor K to the front of the assemblingblock, into which they are carried in the same manner as the matrices and added to the line .in the course of composition or assemblage.

`436`,532,previously referred to. It is provided, however, with a pivoted cover K10, which is formed with a centrally-depending IOO lug or bar K25, which is so shaped as toproject between the lugs or ears Z2 of the spacebars. This cover when closed rests upon the stop K11 and holds the space-bars securely in the magazine, but does not prevent the liberation ofthe space-bars one by one by the escapement mechanism hereinafter to be described. (See more particularly Figs. 1, 26, 27, and 28.)

The release of the space-bars one at a time is effected from the space-bar key K2, (see Fig. 5,) pivoted at K3 and acting upon the escapement-rod K1, which acts in turn upon the end of the pivoted lever K5, (see Fig. 2,) which is pivoted to the escapement-lever proper, K6, pivoted at the base of the magazine K. At the end of the escapement-lever K6 are pivoted the escapement-pawls K7, which are normally held inward against the magazine by the springs Ks in such manner that the pawls K7 will engage one, and only one, of the spacebars in the magazine. Fast to the lower end of the magazine K is the projecting piece K2, which rests in contact with the outer or eX- treme space-bar and holds the series from further downward movement until the outer one is released by the action of the escapement-pawls. )Vhcn the finger-key K2 is depressed through the connections already described, the pawls K7 are elevated and engage under the shoulders Z2 of the outermost spacebar Z and lift it until it is free from the piece K9 and until its upper shoulders are raised above the side of the magazine, when the weight of the assembled series of space-bars forces it over the beveled portion K13 of the magazine K into the channel K', permitting it to drop into position in front of the assembling-star H13, whereby it is forced into the assembling box I. The delivery of more than one space-bar at one operation is provided against by means of the studs K12 on the pivoted cover K10, (clearly shown in Figs. 27 and 28,) which are squared off and formed in such fashion as to permit the escape of a single space-bar at a time. As before noted, the spring guide-piece H14 serves to check the too rapid fall of the space-band by reason of its projecting tongue.

In order to resist the advance of the lengthening line of matrices and to hold them in compact order, I provide the yielding resistant J, which is forked and straddles the guidepiece J', as clearly shown in Figs. 2 and 6. This resistant J is provided with a finger, which projects down and into the assemblingbox, against which the line of matrices and space-bands is assembled. As clearly shown in Figs. l and 2, it is connected to the cord or band J2, which passes about the compound pulley J3, around which also passes the cord J1 to the spring J5, attached to the frame of the machine. As will be clearly seen, the tendency of this arrangement is to draw the resistant J to the right and to oppose the enlarging line of matrices and space-bands,

which is constantly urged forward by the action of the assembler-star'lfl.

The length of the line is determined by the pawl or detent L, which depends from the slotted rock-shaft L2 and'which is adjustably attached thereto by the set-screw L3 in such manner that the length of the line may be dctermined at will. A spring L4, attached to the frame of the machine and to the rockshaft L2, tends to force the pawl L forward into the path of the resistant J, but permits the pawl to be swung rearwardly and out of contact with the resist-ant when the line is full, as shown in dotted position in Fig. 6, so that the line of matrices and space-bars may be shifted to the elevator at the left.

The construction of the assembling-box I is clearly shown in Fig. 6 and consists of a box open at the top and at the two ends, so that the line of matrices and space-bands may pass in and out. It is further provided with shoulders to engage the lower shoulders Y of the matrices, thereby sustaining them. The space-bands are sustained in the assembling-box by reason of their shoulders Z2, which pass over the upper edges of the box. The front of the assembling-box I is provided with a longitudinal slot I/ to enable the operator to see the indicating characters which distinguish the matrices. Vhen a complete line of matrices and space -bands has been assembled, the pawl L is moved rearwardly by the operator against the pressure of the spring L4, and the line of matrices and spacebands, together with the resistant, is moved manually to the left along the guideway M until it is inserted and received within the elevator N, which when the machine is at rest is normally in line with the guide M and assembling-box I. In effect the guideway M is a mere continuation of the assembling-box. It will be seen that by this arrangement and the simple manual transfer of the composed line I am enabled to dispense with the first line-elevator, the transferring mechanism, and their operating-levers and cams, as illustrated in my Letters Patent Nos. 436,531 and 436,582, previously referred to.

When the elevator descends in the manner hereinafter to be described, the resistant J is left free to return to its original position in the assembling-box by reason of the spring connections J2, J3, J1, and J5, previously described. In this return'movement of theresistant J it encounters the bevel L5 on the pawl L and effects the rearward movement of the said pawl against the pressure of the spring L4, permitting the passage of the resistant J to its original position in the assembling-box. Then the operator may proceed to the composition of a'second line, as the operations of justification, locking, casting, slug trimming and delivering, and of the distribution of the matrices and space-bands of the rst line are automatically accomplished in the operation of the machine.
