"ALTET BENJAMIN F. BELLOWS, OF CLEVELAND, OHIO, ASSIGNOR TO THE ELEC- TRIC COMPOSITOR COMPANY, OF OF WEST VIRGINIA.

CLEVELAND, OHIO, A CORPORATION MACHINE FOR JUS TIFY IN G TYPE-LINES.

SPECIFICATION forming part of Letters Patent No. 727,267, dated May 5, 1903.

Application filed January 24,1900. Renewed November 14, 1902- Serial No. 131,392. (No model.)

To all whom, it may concern.-

Be it known that I, BENJAMIN F. BELLOWS,

a citizen of the United States, residing. at

Cleveland, in the countyof Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Machines for Justifying Type-Lines, of which'the following is a full, clear, and exact description, reference being bad to the accompanying drawings.

The object of my invention is to introduce atproper points in an assembled line of type or matrices the proper number of spacers of the proper size to justify said line. The spacers employed to eifect the justification are alike in so far as their construction is material to the presentv invention, except that they vary in thickness, wherefore all references herein to'the size of the spacers has ref-. erence solely to their thickness.

The invention is equally adapted for use with matrix-assembling machines and with type-setting machines. The term type will, however, throughout this specification be used generically to designate the small 2 5 blocks of metal which are assembled to make up the line to be justified whether these metal blocks have cameo or intaglio characters.

Before describing in detail the machine in which my invention is embodied I will state in general terms the principle and mode of operation of said mechanism. As the type are assembled one by one in line, said line is moved along distances equal to each addition to the line, the mechanism employed for this purpose being common to the assembling-machine and to the justifying mechanism. This movement of the line causes the movement of mechanism by which the aggregate width of the type assembled, or, in other words, the

length of the assembling line of type, is measured. Instead of introducing spacers into the .line at the points where spacers are necessaryas, for example, between the words tubes are introduced. The upper ends of these tubes are severally in communication with a like number of spacer magazines.

Each magazine is divided into a plurality of magazine-channels in which are stored spacers of various sizes, each channel, however, containing only one size. Each of these magazine-channels has an escapement which when operated releases one spacer only. This spacer falls into the tube associated with the magazine of which said channel is a part and through said tube is delivered into the typeline. The escapement-operating devices are arranged over aselectiug-plate which carries a plurality of combinations of escapementoperating devices, preferably vertical pins, some of which, depending upon the position of the plate, are adapted to engage with and operate some of the escapement-operating devices. The surface of this plate is divided in one direction into as many divisions as there are escapements, and each of these divisions is subdivided into as many equallyspaced rows as there are tubes. The plate is also subdivided in a relatively transverse direction into a plurality of equallyspaced rows, and these pins are. placed at the intersections of these relatively transverse rows. This plate is capable of moving horizontally under said escapement-operating devices in two directions and is so moved as follows, to wit: It is moved a definite distance transversely of said devices, which are preferably levers, whenever a tube is added to'the line, and this movement of the plate determines the number of spacers which shall be released, and it is moved forward in the direction of the lengthof the levers a distance proportionate to the size of each type added to the line after the line has reached a justifiable length, and this movement of the plate determines the size of the spacers to be released, but does not vary the number. These pins are arranged empirically upon the plate in a plurality of combinations in such man- .ner that whenever the plate stops after it has been moved in said two directions as many pins thereon as there are tubes in the line will be in operative relationship with a corresponding number of escapemen t-levers which are associated with those magazines with which the tubes in the line communicate, and the particular escapement-levers with which said pins are in operative relationship will when operated release spacers whose aggregate size will equal the distance which the type-line is short of its desired length. When therefore the selecting-plate after it has received the two movements referred to is moved upward, these several escapement-levers will be operated, and as a result one spacer will fall through each tube in the typeline and will be left in said line when the tubes are withdrawn, and these spacers will be of the proper size to exactly justify the line. The power for moving the several parts concerned in the justification of the line is in thetmachine as shown derived from electromagnets which are connected in normallyopen circuits. In most cases these circuits are closed automatically and in proper sequence, and they remain closed long enough for the magnets to perform the work allotted to them, and then the circuits are automatically broken. It isnot my intention, however, to limit the primary invention to combinations in which electromagnets are employed to move all or any of the movable parts, because it is obvious that other sources of power to move said parts may be employed if desired.

' The invention consists in the construction and'combination of parts shown in the drawings and hereinafter particularly described, and definitely pointed out in the claims.

I will now proceed with the specific description of the machine shown in the drawings, in which my invention is embodied, and attention is invited to the claims, which define what parts and combinations of parts of the mechanism so described are of my present invention.

The spacers 9 are stored in readiness for use in the magazines 1, 2, 3, 4, 5, 6, and 7, the lower ends of which converge and form contracted necks. A glass plate 10 (see Fig. 13) may form the front of all the magazines. Into the lower end of each neck the upper end of one of the assembling-tubes 23 projects. The lower ends of said tubes are sup ported on a horizontal plane surface 41. Seven magazines and seven tubes are employed in the machine as shown; but this number is empirical and less or more may be used, if desired. Each magazine is subdivided intoa plurality of vertical spacer-channels 8. The several channels in any magazine contain spacers of different sizes. In the machine as shown fifteen different sizes of spacers are employed, the smallest being .04 of an inch in thickness, and they increase in thickness by .01 of an inch, the largest being .18 of an inch thick. The first magazine contains fifteen channels, and each channel contains a stock of spacers which differ from the other spacers in thickness. The second and third magazines contain ten channels each, and consequently only ten va- The magazines 4, 5, 6, and 7 contain, respectively, seven, six, five, and three channels and a corresponding variety of spacers. These numbers are all empirical and arbitrary and may be varied at will. Each spacer-channel has an independent es- In the form shown each escapethe rear plate 11 of the magazines, and it has two prongs 13 and 14, which project through said rear plate 11 of the magazine-channel. Under normal conditions the lower prong 13 projects beneath the lowest spacer and supports the entire column of spacers in that channel. At the same time the other prong 14 does not project into the channel, but is ata position behind but just below the second spacer in the channel, and when the lever is rockedit moves beneath the second spacer and temporarily supports it. The tail 15 of this lever, which normally rests upon a transverse fixed bar 16, acts bygravity to hold the lever in the described normal position. A release-leverl7 is pivoted on a horizontal rod 20 to the rear plate of the magazine-channels. Its upper end enters a notch 19 in the lever 12 above its pivot, and the tail 18 of this lever normally lies in a substantially horizontal position, resting upon a fixed bar 21. On the under side of this arm is a downward-extendin g vertical pin 22, against which specifically the lifting force is applied, whereby to rock this lever and through it lever 12,

- whereby the lowest spacer only is released from the channel. As will be seen from Fig. 12, these rearwardly-extending escapemeutlevers are arranged in a row at equal distances apart crosswise of the machine.

30 represents a selecting-plate which rests in a horizontal position upon a suitable supporting-frame 32 below the row of lever-arms 18. This frame is pivoted on the same axis with said lever 17--viz., the rod 20. Projecting upward from this plate 30 are a very large number of small vertical pins 31. This plate is capable of moving endwisethat is, transversely-of the machine and also forward and backward and during its movements toward its selecting positions moves to the left and forward, as indicated by arrows in Fig. 18. By these two movements a large number of combinations of these pins may be brought directly beneath the operating pins 22. Every time a tube is added to the line this plate moves a definite distance to the left transversely of the machine, this distance being in the machine as organized .025 of an inch. Since there are seven tubes, this plate may move in the direction referred to .175 of an inch by seven equal steps. To understand the arrangement of the pins 31 upon this selecting-plate attention is called particularly to Fig. 18. This plate .is divided crosswise of the machine into as many equal divisions .175 of an inch wide as there are spacer-channels 8 and corresponding escapementsin the present case fifty-six. Each of these divisions is subdivided into seven (corresponding with the number of tubes) smaller spaces or rows (.025 of an inch wide) extending from the front to the back of the plate, and the pins 31 are placed empirically in some of these rows. It will be understood that all of the pins in the various rows of the first division of this plate are provided for operating the escapement of the first spacer-channel under certain conditions to be described. All of the pins in the various rows of the second division of this plate are adapted to operate the escapement of the second spacer-channel, and so on. Fig. 18 shows diagrammatically the subdivision of the plate referred to. Beneath the various divisions of this selectingplate, as shown in Fig. 18, will be found decimal figures which indicate the. thickness in fractions of an inch of the spacers stored in the spacer-channels with which the pins in said divisions are associated. It will be understood that the organizer of this machine arbitrarily determines what sizes of spacers shall be used and in what magazine-channels the different sizes of spacers shall be stored and then empirically determines what spacers should be released under different circumstances to complete the length of the line and that the pins are placed upon the plate in the positions to effect the release of the proper spacers. As before stated, this plate is not only capable of moving crosswise of the machine, but it is also capable of moving forward and backward. The machine as organized is capable of supplying spacers when seven tubes are in the line which will lengthen the line .7 of an inch and when one tube only is in the line .04 of an inch, and it is capable under conditions which will arise in practice gles to the subdivisions first referred to into sixty-eight equal spaces or rows, each being, as shown, .025 of an inch in width. The pins 31 are placed at the intersection of these relatively transverse rowsviz., those run ning forward and backward and those running crosswise of the machine. In the operation of the machine as soon as the type which have been assembled fill all of the line except .7 of an inch this selecting-plate begins to move forward distances proportionate to the thickness of each addition of type to the line, and it will be remembered that for each tube added to the line the plate moves to the left one step-in this machine .025 of an inch. Because of these two movements of the plate and the empirical arrangement of the pins thereon the plate will always be in such position that those pins thereon which are directly beneath pins on the escapementlevers will release when the plate is moved up one space from each magazine whose tube is in the assembled line, and the aggregate thickness of the spacers so released will be equal to the shortage in the line.

The type 9 which are to be assembled to form the line which the present invention is designed to justify, will preferably be stored in suitable magazines. For the purposes of illustration the vertical channels 144 in Fig. 1 may be regarded as the magazines in which these types are stored, and some of these channels also contain spacers or quads,which may be released whenever desired. Each magazine has an escapement-lever 145, which is operated by a vertically-movable releaserod 219, said rod being raised bya finger-key (See Fig. 2.) The type are released one by one, and they fall through a tube 146 onto a shelf 40, which is a part of the supportingblock 41. J ust to the right at the lower end of this type-assembling tube is a plunger 43, which immediately the type falls upon the shelf 40 pushes said type and all of the line which has been previously assembled a difioperate this plunger. The drawings show for this purpose an electromagnet144, whose armature is connected by a link 46 with one of the links of a toggle 47. This toggle when it is straightened out moves the plunger forward-that is to say, to the left-to push the type along, as stated. This magnet is connected in a normally open electric circuit. 'One end of the broken circuit is connected with a contact-finger 48, and the other end is electrically connected to a thin spring 42, which projects up through the shelf 40, directly beneath the type-assembling tube 146. The types fall, therefore, upon the spring 42, which is thereby forced downward into engagement with the contact-finger 48. This completes the circuit of the magnet 44, which thereupon attracts its armature. Thetoggle is thereby straightened out, and the plunger is moved forward, with the result of moving the type forward and ofi of this spring 42, which thereupon springs away from the contact-finger 48. This breaks the circuit of the magnet 44, whereupon the armature falls, flexing the toggle, and this causes the plunger 43 to return to its normal position in readiness to repeat the described operation every time a type is added to the line. When a tube 23 is pushed forward into the line, it strikes the rear edge of this spring 42 and pushes it forward into contact with the pin 49 on the contact-finger 48, thereby closing the circuit of the magnet 44. The result is that the plunger 43 operates as described, and the tube is thereby pushed to the left a distance equal to its Width. Resting upon the same horizontal surface 41 upon which the tubes rest is a horizontal plate 50, which horizontal surface is behind, buta little above, the shelf 40, upon which the type-line is assembled. This plate 50 extends transversely across the machine substantially the entire width thereof. The forward edge of this plate is undercut, whereby it is raised above its support. In the under side of this raised portion are tongues and grooves 51, extending crosswise of the machine-that is'to say, parallel with the assembling-shelf. This plate is connected by links 52 with arms 53, which are secured to a rock-shaft 54. By rocking this rock-shaft this plate may be moved bodily forward or backward,'for purposes to be described. Normally it is in its'forward position, as shown in Fig. 7.

A measuring-block 55 has afoot 56, which rests upon the same surface 41 upon which the plate 50 rests, and the measuring-block itself extends over the type-assembling shelf.

On the upper'side of this foot'are tongues and grooves 57, which engage with the tongues and grooves 51 in the plate 50, whereby the block is guided in its movements. This block always occupiesa position in advance of the line of type being assembled, and the first type in the line is incontact with it. This block is consequently pushed along by the type-line as the several type are added to said line, and the distance between the face of this block and the rear face of the last type in the line is the length of said line.

A supplementary tube 24 forms the lower end of each spacer-assembling tube 23 and upright position even if the tube 23 is inclined. These supplemental tubes are open on their front sides, and each has on its lower .side a rearwardly-extended foot 25, in the upper surface of which are tongues and grooves 26, adapted to engage with the tongues and grooves 51 in the plate 50. When the tubes are moved forward into line with the assembling type and the plunger 43 moves said tube to the left, the tongues and grooves in this foot engage with the tongues and grooves in said plate, and thereby said tube is guided in its movement and held in the assembling type-line. The tube which is next to be forced into the line normally bears against the right end of the plate 50. It is moved forward into the line by an arm 62, which bears against the rear edge of this foot, this arm being fast to the rock-shaft 60. When, therefore, the operator desires to introduce a tube into the line, this rock-shaft is caused to rock, and thereby said tube is pushed into-line, and the plunger 43 immediately pushes it to the left, its foot engaging with the tongues and grooves of plate 50. To cause this rock-shaft to rock with the results stated, the operator presses down on the spacekey 70. This space-key in the construction shown engages with an arm 71 on one end of a pivoted ball-governor tube 72, thereby forcing down the raised end of said tube. A catch 73 on the vertical arm of a pivoted le-.

1 ver 74 projects through a slot 75 in the arm 71, and when the tube is depressed by the space-key this catch engages with the arm 71 and holds it down until a ball 76 in said tube rolls down to the then-depressed end thereof. The ball strikes the projecting end ofthis catch 73, thereby disengaging it from the arm 71 of the governor-tube, which tube under the influence of a spring 77 resumes its normal position, and the ball-governor thereupon rolls back to its normal position therein. An electromagnet 80 has its armature 82 connected by a link 81 with an arm 61, attached to the rock-shaft 60. This magnet is connected in a normally open circuit, one wire of which is connected with the insulated contact-sprin g 83. When the ball strikes the catch 73, it throws the end of the lever 74 up is pivoted thereto, whereby it may occupy an enters the line. This is necessary in order to give the type released from the type-magazines 144 just before the space-key was depressed time to fall through the long typeassembling tube 146 onto the assemblingshelf before the spacer-tube is inserted in the line. This is particularly necessary, because the lower end 147 of this type-assemblin g tube 146 is hinged at its upper end to the main tubes 146, whereby its lower end may swing forward to a position in front of the type-assembling shelf 40, and, in fact, the lower end 147 of this tube is so pushed forward by each spacer-assembling tube when it enters the line. When this spacer-tube 23 is forced to the left by the plunger 43, the type-assembling tube is swung back into the position to deliver the type onto the assembling-shelf. A horizontal arm 65, which is also fastened to this rock-shaft 60, has a pawl 100 pivoted to its outer end. The upper end of this pawl is adapted to engage with ratchet-teeth 104 on the rear side of a vertically-movable plate- 101. Every time this rock-shaft is operated and a tube thereby inserted into the line this pawl is moved up the distance between two adjacent ratchet-teeth on this plate, and thereby lifts the plate. This plate is connected by an arm 102 with the tail 103 of a vertically-movable stepped wedge 105, which is thereby moved up one step. This stepped wedge is located so that its stepped face may be engaged by a finger 37, which is secured to the selecting-plate 80. This selecting-plate is under the influence of a spring 117, tending always to move it to the left, and thereby hold this finger in engagement with this stepped wedge. Everytime the stepped wedge is moved up when a tube is introduced into the line this selecting-plate is permitted to move to the left a distance equal to the height of one of the steps of said wedge, and it is so moved by said spring, and said finger 37 then engages with the next step on said wedge 105. The described mechanism is that through which the selecting-plate 30 is permitted to make one of its movements, hereinbefore referred to-that is to say, a movement in steps of .025 of an inch crosswise of the machine when each tube is added'to the line.

There are two slides in this machine-viz., the main slide 94 and the compensating slide 84. They move transversely of the machine in parallel paths which are also parallel with the path of the assembling type-line. The main slideis provided with a series of ratchetteeth 95, the operative faces of which are onefourth of an inch apart. The compensating slide has a pallet-lever 85 pivoted to it for engagement with said ratchet-teeth. The foot of the measuring-block 55, referred to, has in addition to the tongues and grooves on its upper face, before referred to, other tongues and grooves 58 on its lower face at right angles to those first named, and these tongues and grooves engage with the cooperating tongues and grooves 93 in the upper edge of a vertically-extended fin 96 on the main slide. It will be remembered that the block 55 is moved in advance of the assembling line which contains both matrices and tubes and that its total movement is always equal to the length of the line made up of spacers and tubes. By reason of the described connection between this block and the main slide the latter necessarilymoves an equal distance. The compensating slide, however, moves a distance which is only equal to the length of the line made up of type only-that is to say, it moves a distance less than the distance which the main slide moves equal to the combined thickness of allof the tubes in the line. These tubes are made one-fourth of an inch in width, and, as before stated, the ratchet-teeth on the main slide have their operative faces one-fourth of an inch apart. Every time the spacer-key is depressed the pallet-lever 85,referred to,is operated and the main slide is permitted to move forward onefourth of an inch, because ofthe addition to the line of the spacer-tube, but the compensating slide remains stationary. The mechanism for operating this palletlever is the following: An arm 63 of the same rock-shaft 60, a

which hasbeen before referred to,is connected by a link 64 with an arm 107, attachd to another rock-shaft 108'. This rock-shaft has two arms 109, between which extends a round bar 106, which is parallel to the rock-shaft. A lever 87 is pivoted to the compensating slide, with a notch 88 in its end which receives this bar 106 and maintains its engagement therewith, regardless of the position in which the compensating slide may be. This lever 87 engages with the projecting tail of the pallet-lever 85, and every time the rockshaft 60 is moved this other rock-shaft 108 is likewise operated through the mechanism described,with the result of temporarily disconnecting the twoslides 84 and 94 through the operation of said pallet-lever. The main slide, therefore, moves forward, but the compensating slide remains stationary. These operations are repeated until the line is long enough to bejustified. This will be in practice when the line contains all of the complete syllables of the copy which will go into it. When the line has reached the justifiable condition, it will be found that the compensating slide has been moved along until an upwardly-extending arm 90 thereupon has come into contact with an adjustable stop 121 on horizontal bar 120, which is suspended by its ends from two freely-swinging links 122 and 123. A further movement of the slide, due to the addition of more matrices, moves this bar and consequently causes these links to swing. One of these links has a nearly horizontal arm 124, to which is pivoted the lower end of the tail 1260f another step-wedge 125, which by its position controls the forward movement of the selectingplate referred to. Therefore this wedge is moved up after the arm 90 of the compensating-slide has come into contact with this stop, and the movement is always proportionateto the width of the type added to the line. The

operative or inclined face of this wedge has sixty-eight equal steps which are .025 of an inch wide. The mechanism intermediate of said wedge and the bar 120 is so proportioned that for every.Ol of an inch added .to the line the wedge will be moved up the distance between two adjacent steps, and consequently the plate 30 will be permitted to move and will be moved forward .025 of an inchviz., the width of each step-which is also the distance between two transverse rows of pins thereon. When this plate 30 is in its normal position, before it has been permitted to move by reason of previous movements of either of said wedges the front transverse 'row of pins (the lower row, as shown in Fig.

requires a movement of this plate one step to the left before any of the pins in said row come into proper operative relation with an escapement-lever. When this plate has so moved one step to the left, (at the same time a tube is added to the line,) it will be seen by examining Fig. 18 that a pin 31, associated with the channel containing spacers .06 of an inchin thickness in magazine 1,will be brought into operative relationship beneath the pin 22 on the escapement-lever associated with .the said magazine-channel and that no other pin on the selecting-plate will be inoperative relation with any pin on the escapement-lever. By a second movement of this plate one step to the left another pin will be brought into operative position beneath the same escapement-lever. Another pin will also be brought into operative relation beneath the pin on the escapement-lever of that spacerchannel in the second magazine which con tains spacers .06 of an inch in thickness.

y a third movement of this character pins 31 will be brought beneath these same escapement-le'vers and beneath the pin on the escapement-lever of the spacer-channel in the .third magazine containing spacers of like thickness. This mode of action may continue until when seven spacers are in the line,. although the plate 30 has not been moved forward at all, because the line is not ofa justifiable length. The upward movementof this plate 30 will operate an escapement-lever associated with the channels containing spacers .06 of an inch thick in every one of the magazines. Because of this construction any short line which cannot be justified may nevertheless be spaced with spacers .06 of an inch thick.

By an examination of Fig. 14 especially it will be seen that the stepped wedge 125 does not engage directly with the selecting-plate, but it does engage with the upturned edge of a bar 38, which is rigidly, but adjustably, secured thereto. On the under side of this plate is a yoke 39, through which a shaft ings on the under side of the frame 32.

near one end is a channel-bar 28. tion-roller 136 upon the upper end of a lever passes, whereby the plate'is held down upon the frame 32. This shaft is mounted in bear- To the ends of this shaft two pinions 112 are fastened. One of these 'pinions is engaged bya gear-segment 113 on the upper end of an arm 114, which is attached to the rock-shaft 115. These two pinions engage with rack-teeth 29 on the under side of the plate 30. An arm 118 on this rock-shaft 115 is connected, by means of a link 119, with the armature 131 of an electromagnet 130. The spring 117 is connected at one eudwith a fixed pin 116 and at the other end with a lever-127. One end of this lever is hooked into a slot in the link 119. The spring therefore exerts a continuous force, tending through the described mechanism to send plate 30 forward, thereby holding the part 38 in contact with the wedge 125. The magnet is connected in a normally open circuit; but when the circuit is closed the armature is moved with a force greater than the force of the spring 117, whereby the plate is moved through the mechanism described rearward to its normal position on frame 32. When it is so moved, the stepped wedge 125 falls by gravity to its normal position, and thus prevents the forward movement ofsaid plate under the influence of the spring 117 when the circuit of said magnet is again broken.

On the under side of the selecting-plate 30 A fricenters this channel-bar. An arm 137, which is rigidly attached to this lever, is connected, by means of a link 138, with the armature 139 of an electromagnet 1 10. The lever 127, before referred to, is pivoted to this link 138 at one end, while its other end enters a slot in the link 119. The same spring 117 which acts to rock the shaft 115 also acts through the described connections to rock the lever 135 in such direction as will cause the finger 37'on the plate 30 to press against the stepped wedge 105. 'The magnet 140 is connected in a normally open circuit. When the circuit is closed, the armature-is attracted witha force superior to the force of the spring 117, whereby the lover 135 is moved in the opposite direction, with the result of returning the plate 30 to its normal position, whereupon the stepped wedge 105 falls by gravity to the position shown in Fig. 12. \Vhen the circuit of the magnet 140 is broken, the spring 117 again exerts its force and through the described mechanism moves the plate 30, whereby the finger 37 will always bear against the stepped face of this Wedge.

In Figs. 13 and 14 a vertically-movable plain wedge 141 may be seen by the side of the stepped wedge. The inclined'face of this plain wedge may be below the stepped face of the other wedge. A laterally-extended pin 142 on this plain wedge extends over the top edge of the stepped wedge. If through the action of the plunger 43, which moves the line along,'the compensating slide or the stepped wedge 125 acquire a momentum which carries them past the position in which they should stop, the selecting-plate,

if it were then allowed to come directly into contact with the teeth of the stepped wedge, would prevent the wedge from returning to its proper position. This action on the part of the selecting plate is prevented by the plain wedge referred to, because before the stepped wedge moves up far enough to come in contact with the pin 142 referred to its operative stepped face is above the plain edge of the other wedge 141, and therefore the bar 38 on the selecting-plate can only move as far as the plain wedge will let it. It is not believed that the momentum of the parts will ever cause the plain wedge to be moved up too far. The selecting-plate being engaged in its forward movement by the face of the plain wedge cannot prevent the stepped wedge from falling back into its proper position. When, therefore, all of the type have been added to the line which it should properly contain, the first action of the mechanism is to draw the plain wedge upward and allow the selectingplate to move forward into contact with the stepped wedge if it were not in contact with said wedge before. It will be understood that this plain wedge is not a necessary part of the machine, but is only a precautionary element intended to act when necessary to prevent the selecting-plate from moving forward too far. It may be that in practice this plain wedge will rarely, if ever, serve any useful function; but it is there prepared to serve a useful purpose, if necessary. The selecting-plate having been moved by the described mechanism and its movement having been properly controlled by the two stepped wedges, the selectingplate is in a position in which the proper number of pins thereon are in operative relationship with the escapements associated with the spacer-channels of the several magazines which contain the proper size of spacers to accurately justify the line. The power which directly causes the upward movement of this selecting-plate is furnished by an electromagnet 150. A rod 149, connected with the armature 151 of this magnet, engages with the frame 32. The magnet is normally in an open circuit. l/Vhen the circuit is closed, the armature is attracted, and this rod engaging with the frame 32 swings it and the selectingplate 30 upward upon the pivot 20, whereby the release-levers 17, which swing on the same axis, are operated and a spacer of the proper size is released and falls into each tube in the line and through said tube into the line. It might be here noted that the'upward movement of the frame 32 is limited by a shoulder 34 on an adj ustably-tixed rod 35, which passes through a yoke 33 on the under side of this frame. This yoke normally rests upon another shoulder 36 on the same rod. Following this action the spacer-tubes are drawn backward out of the line and so, also, is the measuring-block 55. The slides are then drawn back to their normal position, whereby the measuring-block 55, acting against the first tube, pushes all of the tubes back to their normal position, as previously described, in readiness to be again used.

As before stated, the power to cause the required movement of the described mechanism is furnished by electromagnets. These magnets are connected in normally open circuits. One pole of the electrical generator 179 is connected with one pole of each magnet. The other pole of the generator is connected with the metallic framework of the machine. When the other pole of any magnet is connected with the metallic framework, the circuit of the magnet is completed. The means for completing the circuit of the electromagnet 44 and of the magnet have been described. The other magnets (except 220) are intended to operate different parts of the mechanism, either simultaneously or in quick succession, and therefore means are provided whereby the closing of the circuit of one magnet will automatically and after a proper in-- terval of time close the circuit of another magnet, and so on until the cycle of operations which these magnets are designed to produce is completed, and the several circuits of the magnets are again broken after the magnets have done their work.

After the line is set up and ready to be justified the line-key 178 is depressed. It contacts with a spring 177, which spring is electrically connected with one pole of the magnet 170. This completes the circuit of the magnet 170, because the line-key is electrically connected with the machine frame. When this magnet attracts its armature 171, the line-key may be released, because the movement of said armature permits a spring 174 to move against an insulated contact-finger 173, which is connected in the circuit of said magnet. Thev armature has theretofore held the spring 174 out of contact with the finger 173. The spring 174 is electrically connected'with a spring 176,which is normallyin contact with the spring 175, this latter spring bei-ng electricallyconnected with the machineframe. The circuit of the magnet 170 is thereby completed through a path which is wholly independent of the line-key. The movement of the armature of this magnet produces two tog results: First, it rocks a lever 180, which is connected by a link 181 with said armature. This lever carries a spring-pawl182, adapted to engage with a toothed extension 143 of the plain wedge 141, whereby said wedge is lifted, so that it no longer prevents the direct contact of the selecting-plate bar 38 with the stepped wedge 125. Second, the same movement of this lever rocks a pivoted ball-governor tube 183, to which it is connected by a link 184, so as to change the inclination of said tube. The ball 185 in said tube rolls to the other end thereof. When it reaches said other end it strikes against thespring 175 and moves said spring out of contact with the finger 176, thus breaking the circuit of the magnet 170, whereupon its armature falls and the ball-governor tube resumes its normal position The ball rolling down to the opposite end of the said tube rolls over a thin spring 187, which is thereby depressed and forced against an insulated contact-piece 186, which is in the circuit of the magnet 150. The circuit of'the magnet 150 is thereby completed, because the spring 187 is electrically connected with the frame of the machine. When the armature 151 of this magnet moves, it causes the circuit of the magnet to he completed through another path, because it permits a spring 152 to come into contact with a finger 153, which is connected with one pole of the magnet. The spring 152 is electrically connected with a spring. 154, and a spring 155, which is normally in contact with the spring 154, is electrically connected with the frame of the machine. The upward movement of this armature 151 swings upward the frame 32, which carries the selecting-plate 30, and thereby the selected escapements are simultaneously operated and spacers are released into the assemblingtubes. The upward movement of this armature also rocks a ball-governortube 156, to which it is connected by a link 158. The ball 157 in this governor-tube rolls down to the depressed end thereof and strikes the spring 155, forcing it out of contact with the spring 154, and thereby the circuit of the magnet 150 is broken, its armature falls, and the governor resumes its normal position.

- The ball 157, rolling down toward the depressed end thereof, rolls over a thin spring 160 and forces it into contact with a contactfinger 161. This fingeris connected electrically with the three magnets 130, 140, and 190, and since the spring 160 is electrically cou nected with the frame of the machine the circuits of these three magnets are completed. The circuits of the magnets remain completed only so long as the ball-holds this spring down, but this'is long enough for the magnets do their work. The magnet 140 attracts its armature and through the mechanism which has already been described rocks the lever 135 and draws the selecting-plate 30 crosswise of the machine to its starting-point; The stepped wedge 105 falls toits normal position, where itacts, as before explained, to prevent the movement of the selecting-plate in the opposite direction. The movement of the armature of the magnet 130 acts through the mechanism described to swing the arm 114, whereby the selecting plate is moved rearward to its starting-place. The stepped wedge 125 therefore falls to its normal position, where it prevents the opposite movement of saidf'selecting-plate, as described. The armature 191 of the magnet when it moves upward permits an insulated spring 193 to come into contact with a contact-fin- 157 rolls off of said spring.

' seven spacers.

ger 192, which is electrically connected with one pole of the magnet- 190. The spring 193 is electrically connected with an insulated spring 194, which normally is in contact with some part of the metallic frame-as, for example, the lug 195 on the rear part of the block, which supports the main and compensating slides and various other parts of the machine. (See Fig. 6.) The circuit of this magnet is therefore completed through a path which does not include the spring 160, and therefore it remains completed when the ball The armature 191 is connected by a link 196 with an arm 59" on the rock-shaft 54. WVhen, therefore, the armature moves upward, this rock-shaft is rocked, and this movement of the rockshaft, transmitted through the arms 53 and the links 52, draws the plate 50 rearward. This (1 raws the tubes rearward out of the line, leaving the spacers in the line, and it also draws the measuring-block 55 rearward out of the line, although it remains operatively connected with the slide 94. The slide 94 is then drawn to the left. This movement may bev effected by drawing downward upon a cord 97, which is attached to the main slide and passes over a sheave 98. The main slide 94 engages with an arm 86 on the compensating slide, and this slide is also drawn backward, both slides reaching their initial or starting position. An insulated arm 99,which is attached tothe compensating slide, engages with the spring 194 when said slide reaches its initial position and moves the spring 194 out of contact with the lug referred to, and thus the circuit of the magnet 190 is broken. The backward movement of the main slide draws back the measuring-block 55, which is, in effect, a part of said slide, and it pushes the spacer-tubes back to their normal positions at, rest. When the circuit of the magnet 190 is broken, its armature falls, rockshaft 54 reverses its movement, and the plate 50 moves forward, its right end serving as an abutment against which the spacer-tubes rest. This completes the cycle of operations, which result in justifying a line of type and of returning the mechanism to position in readimess to go through the same cycle of operations. The justifying mechanism, as shown, however, includes other mechanism not heretofore described which have important functions to perform. For example, it is desirable and perhaps practically necessary to provide some means which will inform the operator when the line is nearly full and show him approximately how much more matter he can add to the line. Before describing the means for this purpose attention is called to this factnamely, that the more tubes there are in the line the shorter must be the type-line which can be justified. For example, if seven ICO tubes are in the line, room must'be left for If the smallest spacers (.04 inch) are used, they will necessarily occupy .28 inch of space, whereas if only one tube is in the line only one spacer will be required and that may possibly occupy only .04 inch. It will be necessary to hear these facts in mind in order to readily understand the m echanism to be now described.

A-lever 205 is pivoted to the front side of the housing 204, in which the plate 101 is guided. To the lower end of this lever a bar 206 is pivoted, and this bar rests and slides upon an extension of the bar 120. On the side of the bar 206 an insulated contact-plate 207 is secured, and this plate is electrically connected with an electrically-operated signal, which may be an incandescent lamp 210. The other terminal of the lamp is connected with the generator 175. The lever 205 has a pin 208, which passes through an arc-shaped slot 203 in the housing 204 and into an inclined slot 101 in the vertically-movable plate 101. As this plate is moved upward, as described, when tubes are introduced into the line the lever 205 will be swung to the right, and the contact-plate 207 will consequently be moved in the same direction. After the line has reached ajustifiable condition the bar 120 begins to move to the left, and sooner or later (depending upon the position of the contact plate 207, which, as stated, depends upon the number of tubes in the line) a tinger 128 on bar 120 will strike this contactplate, thereby completing the circuit of the lamp, which flashes the signal that the line is nearly as full as it should be to be justifiable. Theactual space which may now be filled in with additional type is approximately indicated by the distance between this finger 128 and a contact-spring 212 on the lower end of a swinging lever 213. This lever is insulated from the machine, but is electrically connected with the magnet 220. The operator must see to it that this finger 128 shall not touch the contact-spring 212, because thereby the circuit of this magnet is completed. The function of this magnet is to lock the mechanism whereby the type are released, and it effects this result through the following mechanism: The escapements of the typemagazines are operated by vertically-movable release-rods 214, which are connected with finger-keys 211. A frame 216 is pivoted adjacent to the upper ends of these releaserods, and it has a cross-bar 217, which may be swung over the tops of all of said releaserods. The armature 221 of the magnet 220 is connected by a link 222 with an arm 218 of this frame. When, therefore, the circuit of the magnet 220 is completed, this frame will be swung on its pivot until the crossbar 217 is over the tops of the release-rods 214, whereby the vertical movement of said. rods is prevented, which of course prevents the operation of the escapements by which the type are released. This mechanism is called the key-lock, and obviously it does not matter whether this frame engages with one part or another of the train of mechanism of which the type-releasing keys are commonly at one end and the type-escapements at the other. The lever 213 has its position varied to carry the contact-spring 212 toward the finger 128 through the contact with it of a friction-roller in the end of an arm 111, which is attached to the vertically-movable plate 101. It is obvious that the more tubes there are added to the line the farther will this lever be swung to the right, and consequently the sooner will this contactspring 212 meet the finger 128. In other words, the more tubes there are in the line the shorter will be the actual type-line when the type-release mechanism becomes locked.

It will not infrequently happen that more than seven spacers are required in a line. The machine as organized is only adapted to deliver seven spacers through the tubes. If other spacers are introduced into the line, they must be in the form of plain quads and must be introduced by some other means than through the tubes. As is common in ma-' chines of this class, quad or plain spacers are stored in magazines like those which contain the type, and they are capable of being released by similar finger-keys. As shown in the drawings, 211 indicates a quad-key, and 219 a quad-release rod, which rod by its vertical movement operates the escapement of a quad-magazine which contains quads .06 inch wide. The operator may by depressing this quad-key release a quad and cause it to enter the line. The operator, however, becomes accustomed whenever a spacer is desired in the line to depressing the space-key 70, and therefore mechanism is provided in this machine whereby the depression of this space-key after seven tubes are in the line will have no other effect than to cause-the operation of this quad-release rod, whereby a quad is added to the line.

By reference particularly to Figs. 16 and 17 a bar 162 is seen pivotally connected with the quad-release rod 219, and under normal conditions it hangs vertically downward from its support. It has a forwardly-extended arm 163, in which there is a vertical slot 164. The pin 165, which connects the link 64 with an arm 107, passes through this slot and through another slot 66in the link 64. Until seven tubes are in the line this lever 162 is back out of the way of all moving parts; but after seven tubes have been introduced into the line the lever 162 is swung forward over a pivoted pawl 67 on the end of an arm 68, attached to the shaft 60.

Looking now at Figs. 8 and 9 particularly, a beveled lug 91 will be seen on the inner face of the main slide 94. If seven tubes are introduced in the line and comparativelyfew type, this main slide will have moved independently of the compensating slide such a distance that this lug will come into engagement with the tail 78 of the lever 87, and thereby this tail will be depressed. This, through the described intermediate mechanism, will cause the rock-shaft 108 to be rocked,

and this rocking action through the link 107 will draw the bar 162 forward and hold it forward during the assembling of the remaining portion of the line of type. When, now, the space-key is depressed and by the action of the parts described the rock-shaft 60 is rocked, the pawl 67 on the end of the arm 68 on said rocloshaft engages beneath the lower end of this bar 162 and pushes it upward. This pushes up the release-rod 219 and causes the release of a quad, which falls through the type-assembling tube into the line. It might be here stated that whenever this beveled lug 91 on the main slide comes into operative relation with the tail of the lever 87 the front end of the pallet-lever 85 is in engagement with a shoulder 89 on the end of the main slide 94, whereby the movement of said slide 94 is necessarily accompanied thereafter by a corresponding movement of the compensating slide.
