To aZZ whom it may concern.-

Be it known' that we, WILLOUGHBY W. STREET and CHARLES LESLIE TRAVIS, citizens of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Justifying Attaehments for Matrix-Making Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as'will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to matrix-making machines of the single-die class, wherein the impression is madefn the matrix material by a series of dies brought in succession 'tothe printing-point. In this class of machines a printed impression, in appearance like newspaper or book print with justified lines, is produced by differentially-spaced dies, correspending dilerential feed movements of the matrix material,and the proper distribution of Spaces from pre-prepared eopy between words. The copy isl prepared by measurement with the common scale used for the dies, the feed movements of the matrix-machine and the newspaper line,and the notation thereon of the extra spaces required to till out the line. In practice this preparation is effected on a type-Writer having' a differential registering device or Space-indicator which registers like spaces forlikecharactcrs, the same as thematrix-machine, the extra spaces lett. over, if any, at the end of the line being indicated by a numeral. The numberof extra spaces required vto be thrown in between words is thus predetermined and made known to the operator on the matrix-machine. In the plan generally hitherto pursued theoperator after noting' the numberofwords in the line and making a calculation as to the best distribution of the extra spaces, throws the same in between the words by a proper nianipulation of the space-keys. As the number of extra spaces and the number of words-in a line varies widely, this requires the most careful attention, and the.

best of operators will frequently make a mistake, thus failing to justify the line, necessitating the destruction of the matrix.

The object of our invention is to provide a machine by which the distribution of the extra spaces may be automatically effected. To this end we provide a mechanism which will vary the space-feed movement, so as to put in between Words other than normal spaces, and by first predetermining the extra spaces in the customary manner and then adjusting the mechanism to make the required variation oi the space movement, the extra spaces are distributed automatically by the operation of the normal space mechanism of the machine with vabsolute certainty and precision. as the operator is concerned, into simply setting a pointer at the total number of extra 'units and then operating the machine for normal spacing, just as it there were no extra units of space to consider'. In other words, we provide a mechanism for automatic justiication, resulting; in a great saving` of material and time and enabling the employment of lower-priced operators.

Though capable of general application, our invention was especially designed for use in connect-ion with matrix making machines, illustrations of which may be found in the Patents Nos. 414,39?) and 414,400, issued to George A. Goodson of date November 5, 1889, and we have shown the invention as applied to such a machine,

In matrix-machines of the general character to which theV present invention is applied the dies are carried onione end of a swinging and sliding lever having a hand-key at the other end moving over au index-plate on the bed. Thefeedmovementsarecontrolledelectrically from the index-plate, the act of seleetinfY the characters on theindex-plate serv- 111g to align the selected die and to close acircuitJ for eltecting,r the. proper corresponding setA of space-keys are connected in multiple for electrically controlling,r the matrix-material vcz'trriag-e to eilect the proper spacing between irords.

ln the accompanying,r drawings, Figure I is a plan view of a matrix-machine embodying our invention, some parts being removed. Fig. II isaside elevation of apartof the same, the one unit space-key being removed. Fig.

Fig. IV is a right side elevation of same; Fig. V, a let`t-side elevation with some parts broken away. Figs. VI and VII are front elevations of same with face-plate removed a-nd some parts broken away, showing two extreme positions of the cam-plate and switch. Fig.

VIIIv is a section on line X X' of Fig. VII, and

Fig. IX is a front elevation of some parts detached.

A is the table on which the machine is mounted.

B is the bed-plate of the machine.

B is the index-plate with perforations or key-seats a.

HB2 is the die-carrier.

B3 is the matrix-material.carriage under tension. (Not shown.)

B4 BS are the escapement and stops' for controlling the same. Five of these stops are movable and the sixth is stationary.

b is the electro-magnet for releasing the escapement.

b b2 b3, '&c., are the electro-magnets for controllingthe stops B5.

C ,C2 are respectively the positive and nega tive binding-posts of a generator.

D is the outgoing wire charging the entire bed of the machine. i

D2 is the return-wire of same coming froi escapement-magnet.

1,2, 3, 4,5,and 6 represent thc feed-circuits. They are all branches of the main circuit, taken from the bed passing through the respective groups ot contacts (not shown) under the index-plate, and, with the exception ot No. 6, all passing through the respective corresponding stop-controllin,f.,1r feed-magnets. No. 6 passes directly to the escapement-magnet, permitting the escapcment to throw to its limit against the stationary member of the stops.

E E2 E3 E4, &c., are a set et' spacing-keys pivoted on plate F,charged by wire D3 or otherwise from bed B. These space-keys correspond to the respective feed-circuits'l 2 3 4, &c., and are all provided with corresponding contacts c e2 e3 c4, the., thereunder. (Only e2 shown.) Each of thesecontacts, with the exception of c2, is directly connected up in multi ple in the corresponding' fced-circuit. 'lhe space-key branches or loops ot the circuits are normally open at the keys, the latter being held away from the contacts by a springbailF. Wil-h these space-keys and theircleetrical connections the feed movements may be controlled by hand to effect any spacing desired and is the means hitherto generally used on such machines for this purpose. With our attachment the normal spacekey contact et is not directly connected in the corresponding feed-circuits, but the connection ismade indirectly through the justifier to a switch or pivoted contact movable over fixed contacts corresponding to and connected with said spacingcircuits. lhis switch is automatically operated by a cam-plate, which is set or tizitwfmimmmmmamm .W

4adj usted by hand at the beginning of the line f cuits are indicated in Fig. I 'and marked 2 3 Referring now to Figs. III to IX, inclusive, the detailed construction of the justifier is as follows:

G G G is a suitable case-ot' which G `is the face-plate, G the body, andG the baseplate for securing the ease in position.

' H is the switch or pivoted spring-contact under tension by spring Il', pivtally attached at itsupper end to a hardrubber plate h,`se sured to the back of the case.

I-l2 Ila H4, dac., are contacts fixed at 'short distances apart to a hard-rubber plate h ,secured to the back of the ease, directly under and inV a position to make contact with the free end of the switch H. The switch I-Iis in circuit with contact e2 under normal space-key E2, and the fixed contacts II2 113, dsc., with the spacing-cireuits by branches 2 34, &c., as before noted. l l

K is a post or pintle fixed to the back plate of the case at about its center and projecting outward throughl the face-plate ol the same.

L isa cam-plate with extended hubs mounted on the post K.

M is a shield or cut-off level' having 'au extended hub loosely mounted on theinnerhub of cam-plate L.

N is a pawl carrying lever having hub loosely mounted on the vhub of the lever M and is provided with a pivoted spring-pawl N at its ,outer end.

I I is a lever pivoted at the lower end ot' its stem to the case.

P" is an arm or bar of -hard rubber pivotally attached to the lever l and is slotted to receive avstud h of the switch ll. 'lhc arm l of lever Pis provided with notches or teeth at its upper surface for engagement with a heel-like extension N ot' the pa\vllever N. The stem of the lever I is also slotted near its upper` end to receive a stud M on an angularlyextended arm lll of. the shield-lcver M. also provided with an outwardly-projectng cam-stud p.- Q is au operating-arm or connecting-rod connected at one cud to the pawllever N and at the other to an extension ot the normal space-key'l12. 'lhc cam-plate L is provided withr a series of cam-surfaces l, l", l, Z, l5, and l", located at different distances from ,the common axis or center, the latter five of which k,cam-surfacesare madeeontinuous in abroken ath and correspond, respectively, to the fixed contacts ll24 ll, &c., while the first named or surface is located so as to --have its beginning entirely outside the outermost of the others viz., l" -and its terminus 'lhe arm l of the lever l is IOO at the same radial distance as the innermost of the same-viz., Z2. These cani-surfaces may be provided on the cam-plate in any suitable way. As shown, the'cam-pl'ate is suitably cut away for the purpose. When the parts are in proper position, the stud p on the arm P of the lever P engages with one or another of said cam-surfaces;

The Vcam-plate L is provided with ratchetteeth q on one-halt of its periphery, `with which the pawl N on pawl-lev-erN. may be made to engage for turning the cam-plate.

R is a bail-shaped lever pivoted in lugs r, secured to the case, having its ,baill portion outside and in position to be made to bear against the switch II. lt is provided with a crank-arm R. A light wire S with a loop is attached at one end to the crank-arm R. A coiled spring T has its body mounted for a base of resistance on the hub of the camplate and has one of its ends attached to the wire S and the other passed through the loop thereon and attached to the pivot-post of the pawl N on lever N. The result is that when the-pawl-lever is thrown forward (upward) to its limit the bail R is also drawn up, forcing the pivoted contact H tightly against the corresponding fixed contact, over which it may be at the time.

V is a stop fixed tothecase for limiting the throw of the pawl-lever.

\Vis a pointer mounted tightly on the hub of the cam-plate outside the face-plate, with its free end over the dial-plate.

t is a'hard-rubber face on switch I-I.

It should be noted thatthe number of ratchet-teeth correspond to the number of exl tra units indicated on the dial-plate and the maximum number of extra units of space for which provision is made. It should also be` noted that the shield-lever M is of like radius with the cam-plate and that its outer segmental end may be made to coincide through a greater or less portion of it's length with the periphery of the cam-plate and prevent the pawl N from engaging with the teeth q.

Hence the number of teeth with which the pawl may be made to engage or the length of its throw will vary according to the position of the shield-lever M. This position of the shield-lever, in virtue` ofr its connection-(by Ml\l' and theslot in stein P) with the lever l, is made to depend on the corresponding relative position of the cam-studi). This lever and stud is prevented from moving'to the left out of its proper position by the heel N engaging the proper tooth of l. Note, also, that the tension 4on the pivoted contact or switch ll tends to throw it to its outside limit in the slotted arm P.

\Vith the construction in unit and especial attention to the above-noted features and the electric circuits, the operation may be readily understood, which is as follows: When the pointer is at 0, as shown in Fig. lll, the cani-plate and the other parts are in the respective positions shown in Fig. \'I, the pivI oted contact or switch bearing against the twounit fixed contact ll2 and the cam-stud 1J being at the extremity of the notch between cam-- surfaces Z and Z2. This, for convenience, may be called the normal position. In this p0- sition the operation of the normal space-key E2 will close a circuit through stop-magnet b2 and the normal two-unit space will be thrown exactly as it the j ustitier attachment had not been used'. It now the pointer be .turned to 525 on the dial-plate, the camplate will be carriedwith it and all the parts will be in the position shown in Fig. VII, the cam-stud p will be bearing against the cam-surface Z6 at its limit, the switch H will be bearing against the xed contact H, and the shield-lever M will have been retracted, so as to permit the pawl-lever a throw ot four ot teeth q at a stroke. It' now the normal space-key E2 be struck, the following will result: first, the feed-circuit will be closed through LH6 to escapement-magnet b, permitting the escapement B3 to move to its limit, feeding the matrix-carriage forward six units ,of space, or varying from the normal space between words by four extra units; second, the pawl-lever will throw the cam-plate forward four notches, corresponding to the extra units of space thrown at the feed. As there are twenty-five teeth on the'cam-plates, it is evident that six strokes on the key would revolve the plate to within one tooth of its normal position. On the sixth stroke of key E2, in virtue of thelocation of the outer cam-surface Z, the cam-stud p would be struck thereby and forced toward the post or center K `until in same radius with cani-Surface Z3, carrying downward the arm lt and throwing upward the shield-lever M to cut o'if from the pawl all except one tooth of the plate. Mean- 'time the spring T, wire S, and bail R would hold the pivotedlever against 1l6 until the completion of the stroke; but the instant the key is released and the operating-lever Q and pawl-lever N fall to their lowermost position the bail R-is released from its tehsion and the pivoted contact H,being free, is instantly thrown by its tension-sprin g to its limit in the vslotted arm P, and as the arm is one space from normal the free end of the contact ll is over contact 113. 'The seventh stroke closes the circuit through l1"3 and the feed-magnet b3, throwing in the one remaining extra unit, and by surface Z, dsc, as before described, brings all the parts back to their normal position, as

shown in Fig. VI. It is evident t-hat'it there had been twenty-five extra units, indicated on the prepared copy, required to be thrown in to justify the line and there had been eight words (or seven spaces) in the line, the same would have been distributed by the addition ot` four extra units to each of the first six spaces and one extra unit to the last. It would rarely ever happen that there would be twenty-tive extra spaces to distribute. The number seldom exceeds fifteen and averages about seven or eight." The line willsel- IOO IoV

dom contain less than six words or tive spaces. The device has been constructed accordingly.

' Hence for all the camsurfacesls, Z4, and Z5.

ve throws of the pawl are allowed to bring 5 the parts from. the limit of the surface backto normal.` ,For Zi, as before seen, a possible seven is provided. Suppose there had been l oneextra unit. 'The pointer would have been set overl on the dial, the cam-wheel `would camstud wouldbe near the terminus of camsurface Z3, andthe pivoted contact on fixed contact il. Then the Erst stroke on the normal space-key would throw in the extra ,unit and bring all the parts back to normal. Suppose there had beeniive. One extra would have been added to eachl of tive spaces. Suppose ten extras and five spaces. The cam-stud would work on calli-surface Z4 and the pivoted contact on H, throwing in two extra units at each of the five strokes. If fifteen extras and five spaces,it operates on Z5 and 115, throwing three Iextras at each of the tive strokes. If twenty, on ls and H6, throwing four extras each stroke. In other words, the divisionsyare at 5, 10,,and 15. From 1to 5 it throws oneextra unit of space, from 6 to10 two extras, from 1I to l5 three extras, and from 16 upward four extras each stroke. Of course it is apparent that if there be six "words (tive spaces) andless-thanive extras, they will all be distributed between the earlier words o'f the line. So with intermediate numbers between 5andl0,l0and 15, ,l5 and 20. In case there were onlyl tive words, (four spaces,) these intermediate extras would be thrown in uniformly between all the words.

In that event, or other cases where thev line' contains less than six words, (live i spaces,) there might be one or two extras left over after the last space was struck; but this can, in ,all except rare instances, be entirely 1 avoided by an additional or slightly-different manipulation of t hedevice--viz., byadjusting the cam-plate to throw a larger number of extras in all or a part `of the key-strokes. For example,supposethelineeontainonlyfour words or three spaces and there be twelve extras. 'lhc operator will first swingthepointer around to itslimit, (or at least past l5,) s0 as to bring cam-surface l into play and the pivoted contact to operateon ll", and then return the pointer to 12 on the dial. For each' of three strokes of the key there will be then thrown in fonr` extras, distributing the entire twelve. Se if thorewere ten extras and onlyfour spaces thc pointer would be first turned past ll lon the dial and then back to l0, causing surface l and contact Il to operate for three strokes and Z2 l l2 on the fourth throwing lin three extras between. the first four-words and two extras between the last two words.` 'ihe device is therefore within the range of all ordinary conditions perfectly automatic when properly adjusted at the beginning of theline. 'lhe principle'is of course have been turned one tooth from normal, the

tional cam-surfaces and `fixed' contacts the device could be made to throw five or six extras each stroke. Practical experience has demonstrated, however, that the device as shown hassuiiicient range for all ordinary l work. Itl will also be understood that `the circular form is simply a matter of convenience. `The full set off space-keys, from 'one to six units, is left on the machine for use in case of necessity in extraordinary instances. For example, it might happen that between the last two words it would be desirable to throw only one unit ot' space instead of thel normal amount oftwo units, the total extras and one more unit having-been thrown in by the justifier between the other words. Oi', again, suppose the unusual case of eighteen extras and on1y fonr words, (three spaces.) .Inasmuch as thel highest number of extras which the device can add at a throw is four, it is evident that in that particular rare instance resort must vbehad to the space-keys,

using `both the normal two-unit plus the'sixunit key for every one of three spaces. Such extreme cases require provision to meet, but are of such extremely infrequent occurence as not to make it worth while to add' addi- 'tional' feed-magnets to the matrix-machine and additional contacts and cam-surfaces to thejustifier in order to make f'the same exhaustive.

The device shown in` Figs, III to IX, inclusive, though designed and shown applied as a justilierfor matrix-machines, is, broadly viewed, an automatic switchand might be of use otherwise than in matrix-machines.
