Be it known thatl, LOUIS ALBERT DIss,

' citizen oftheUni tedStates, and resident of Then, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Machines for Making Dies or Matrices for the Manufacture of Ty e forTypet-lVriting Machines, &c., of which t e following is a specification.

, The present invention relates primarily to a machine for cutting diesor matrices for ty e to be used in typewriting machines. n .one classfof typewriting machines, a

cylindrical platen is employed and the faces surface; t

ofthe type are made to-iit this cylindrical iat is, the faces of the type are in surfacesof single curvature, just as the surface of a cylinder is of single curvature. In

another inake of typewriting machines, the platen is-polygonalj and the faces of the'type are fiat orplane to'fit the plane faces of the prism. fThe type for these classes of type limiting machines are commonly formed on a I block of steel provided with a tapering shank.

In some cases, the'saidblock is provided with two (r more) type orcharacters, as upper and lower madeby dropping or pr'essingfor y rolling' Whenthe type are made by ,dro

ing. the dies or matrices must ave the form (inverted), of the-finished type; and the said case letters. These ty e may be ping or press 7 dies, when they are to be used in the rolling spond "surface of a sphere or-outer surfaceof a process, must have their parts, which corree to or form the'faces of the type, in the cylindrical ring.. The foregoing remarks type lie in the surface plane-faced type are to be made by dropping applyonly in the case where the faces of the of a cylinder. If the or pressing the dies have their faces in ,p anes; andif the type are to be made by rollin thenthe dies must have their faces whidli make or form the faces of the type in the surof iron or steel, and must therefore be (proface of a cylinder. i 7

Types for typewriting machines are made duced from hardened steel matrices or less Heretofore such dies have been made by fore--- ing master types into soft steel and hardening the latter after the impression-is made.

This process is open to two objections, the

first of which ar ses from the necessity of hardening the master type after it is shaped, since-in hardening the type issomewhat deformed. The second objection arises from the necessity of forcing the master types into soft steel and of subsequently hardening the "latter, since the matrlx is strained by the compression and the strain is removed by the subsequent heatin so that the impressions are disturbed. hus from two ndependent causes' deformities exist in matrices formed by the usual process. Both of these objections are overcome by my invention of forming a type matrix by a cutting process, since practically no deformation ofthe char-- acters occurs in hardening acut matrix.

The principal object of this invention is to provide a simple and efiicient machine for cutting dies or matrices from which to form types whose faces are curved to match substantially the curvature of the cylindrical writing-machine platen upon which they are intended to print- The invention consists of certain'features of'construction and combinations of devices hereinafter described and more particularly pointed out in the a pended cla1ms. 4

The invention is illustrated in the accompanying drawings'forming part of this specification in which,

The same art, in the various views, will be found to be designated by the same numeral of reference.

Referring to the formof the invention shown in Figs. 1 and 2 and the figures showing details of parts shown therein, the reference 1 indicates a hollow standard or casting provided with a platform 2 at the top thereof. 3 indicates a head or standard cast in one with a horizontal bed or plate 4 which isbolted to the platform byscrews 5, which ass through the late 4 and en age threaded oles in the plat orm 2. The head 3 is providedsw ith a pair of bearings 6 and 7 disosed one over the other. The plate 4 is ored horizontally at 8 to provide a bearing for a rock-shaft 9, which is formed or vided at one end with a cross head 1 0, an the arms "11 and 12. The arms 11 and 12 are bored at13 and 14 to provide bearings for a shaft or pivot pin 15. After the rock-shaft 9 perforation guide plate or pattern 0 amp.-

respectively a longiping or pressing Th shaft17 which-5 passes through a transverse perforation the collar and a transverse 19 in the shaft. The pin or shaft 17 fisof a length suflicient to roject beyond bosses 20 at each side of the collar 1 6, toprovide bearingsv for the forked end 21 of an actuating lever or stylus carrier 22} The prongs 2-1 are provided with-perforations 23 in line witheach other to fit overthe ends of the pin or shaft 17, and the prongs, the collar, andthe rock-shaft are secured together by means of screws 24 and washers 25, the said screws entering threaded holes 26 in the. ends of the ivot or shaft 17.

The die-b ank "-hold er 27 consists of a block bored transversely at 28 to receive the ivot or shaft 15, above referred to, and bywhich it is held between the arms or forks 11, 12 of the rock-shaft 9. The vise block or dieblank-holder 2.7 is made less in width than the distance separating the said arms 11 and 1-2, for a purpose presently to appear; The top of the vise is formed with two extensions 29 and 30 to provide a seat or bearing for the reception of the removable jaws 31 and 32.

e jaw 31 is L-shaped to fit the angle between the extension 29 and the horizontal top of the block 27. The inner vertical surface of the jaw 31 makes an obtuse angle with the top of the horizontal part of the jaw 31 for a lpurpose presently to appear. The jaw 31 is eld in position relative y' to the block 27 by means of a screw 31?. Th vided with a couple of pins or projections 3.3. on its vertical arm, ,and it is also provided with a die-blank-catch 34 carried by an angle lever 34 pivoted thereto at 35 on the vertical part thereof and with a spring 36 secured to the horizontal lever 34 upwardly against a 'sto -pin 37. The lever 34 is bent upwardly and t en horizontally, as at 38, to provide a finger piece e jaw 31 is prorpart thereof, and pressing the whereby the catch 34n1ay be operated. The

j aw- 32 rests on the horizontal part of the jaw 31 and its inneror die-clampingface 39 makes an obtuse angle with the said horizontal portion of the jaw 31. The 0 posing or dieblank clamping surfaces of t ejaws 31", 32, are thus adapted to co-act with tapering or segment-shaped die-blanks 40 to securely hold the same when the jaws are forced toward each other by means of a screw 41, which engages with a screw-threaded perforation in the extension 30 and bears against the back surface of the jaw 32, as shown in i Fig. 2. Each die-blank 40 is provided with a notch or shoulder 42 for the eception of the catch 34 hereinbefore referred to. The dieblanks 40 are placed in position between the jaws of the vise by pressing down the lever 34*, thus. moving the catch 3. out of the way and then inserting the blank between the )ins 33 and the catch, with one end of the lankbearing against thepins,- after which 1 the lever 34 is reieased toallow. thenos'ecr' catchto snap into the notch 42. The .j aw 32,

which has previously been loosened'is now tightened up by the screw 41 and the die beyond the arms 11 and'12. Screws 45 and washers"46, thefirst of which engage screwthreaded holes 47 in theends of the shaft 15, secure the said parts together, see Fig. 1 more particularly. v The ends 48 of the yoke 43 are forked (see Fig. 8) and the prongs of these forksiare perforated or drilled at 49 to receive the ends 500i a forked-linkfiL. The ends 50 are perforated at 52 to correspond-with the holes 49 and are secured to the said forked ends 48 by means of pins 58, which fit in said lengthwise thereof or u slot. At one end; the s eeve 56 is provided holes. At its other end, the said forked-link 51 is connected, with the actuating-lever 22 inthe following manner :,One of the prongs 21' of the lever 22 is provided with an extension 54 which overhangs the said prong in- "wardly as shown in Fig. 14. Thisextension .54is1previded with a rectangular slot 55 parallelwith the axis 17 of the lever 22. The

a figure proportioning sleeve 56 (shown in detail inFig. 18) is rectangular in cross section. andfits the slot 55 widthwise and isslidable and down in said with shoulders 57' which co-act with the end surface 58 of'the extension 54 to revent the sleeve from passingthrough the s 0t, and the other end of the sleeve 56 1s reduced and providedwith an external screw-thread 59. The

sleeve 56 is bored longitudinally at 60; and this bore is parallel with the axis 17 when the sleeveis in proper position in the slot'55.

'lhedistance from the shoulders 57 to the end of the sleeve where the reduced screw-threaded portion joins it, is equal to or is slightly less than the lengthof the extension 54; the

' nut .61 on the thread59 and washer 6'2 lock or hold the sleeve 56 in any position in the slot 55 to which it may be adjusted. Apin 63 providedwith a head or finger piece 64fits closely within the hole 60 of the sleeve 56 and is of a length sufficient to project beyond the same, as shownin-Fig; 1. The projecting end of said pin 63 rovides a pivot for the end 65 of thcforkedink 51., said link being perforatedat 66 tofit upon said pin. By the described means, the motion of the lever 22 a about the axis 17 .is communicated to the yoke43. v V l The means by which the yoke 43 communicates this motion to the vise and so moves it about orwith'the axis 15 will now be described. 'Ihe vise-block'27 is provided with-two arms 67 and 68 projeotin'g-down wardly therefrom atopposite sides of the yoke-43; the arms 67 and 68 are, provided with screw-threaded perforations and with adjusting screws 69 and 7 O engaging said per-- 'forations and adapted'to bear at their ends against opposite sides of the yoke 43,. as shown in Fig. 2. Jam-nuts 71 and 72 upon the screws 69 and are also provided. The screws 69 and 70 serve to adjust or vary the position of the vise-block 27 and die-blank 40 relatively to the yoke 43 and to the" cutter and to secure these parts in such adjusted positions. These screws also serve in conjunction. with the said yoke to secure the vise in any position along the shaft or axis 15 to which it may be adjusted.

The actuatin -lever 22- is shown as being hollow or bored out at 73 to receivea sleeve 74 therein. A-set-screw 7 5 engaging a screwthreaded hole in the lever 22 secures the sleeve 74 against displacement. The sleeve 74 is closed at its upper end 76 and is provided with a slot 77 near its lower end. A tracing-pin 78 fits within the'sleeve 74-and is provided with a pin 7 9, which passes through the slot 77, thus limitingits motion longitudinally of the sleeve and providing .a handle for lifting it. A helical spring 80 inserted in the sleeve 74 bears against the closed end 7 6 of the sleeve and the top of the tracing-pin, pushing the pin outwardly. The column or standard 1 is provided with a vertical row-of screw-threaded holes 81 at the front thereof, these holes being in a-rectangular piece or guide 82 formed interal with or attached to the said column. A slide 83' is provided for co-action with a guide 82, said slide being formed with jaws 84 which embrace the edges of the guide. The slide 83 isprovided with a vertical slot 85. A fastening screw 86 passing through the slot and engaging with the corresponding hole 81 secures the slide 83 in the position from the s ide 83 and is provided with three used. A latform 88 projects horizontally pins 89 arranged to co-act with a side and i an end of a rectangular or square guiding plate or pattern carrier 90. The platform is also provided with'clam ing jaws 919projecting from bars 92, as siown in Fig. '27. The bars are formed withprojections 93 which are provided with screw-threaded perforations parallel with they bar. l Clampingscrews 94, engaging the perforations, have their working ends in opposition to the jaws 91. The platform 88 is provided with suitening s 95 for the insertion of ably shaped o ich are then turned to bring the clamps w them over the pattern-plate 90, after which this same pattern plate and pattern letter ing. aflange 101 at other .suitable means.

Z-In Fig. j38-one. ofgthepins 89 is replaced by plate 96 which is at tached to the platform 88 by'nieans of a screw 97and dowel pins 98; a projection 99 on the plate 96 serves the functions of the pin89. V-

In Fig. 25 I have shown the pattern plate 90 having the letter K formedin its surface by the pattern groove 90*, and in Fig. 1

are shown in position in the machine. It will be observed from an inspection of Fig. 1 that the pattern plate isso positioned in themachinethat-hnes extending from top mb ttfom of the letter wouldbe formed by the swinging. of the Work holder about theaxisthat is nearest the point of the cutter that is to say, in the form of the machine hereshownj, about the fixed axis.

The mechanism for cutting the die or t3 pe Willnext be considered. 'As above stated the head 3 of the frame or casting is provided with two lugs or bearings 6 and 7" arranged one over the other. These bearings are perforatedor drilled vertically and the lower bearing 7 is provided with arbus'hin'g 100 havone end thereof and insorted in the bearing 7 from aboveQ: The

or sleeve 102. The cutter operating spindle or sleeve 103-fits 'n and passes-through the bushings 100. and 102, and is'provided between said bushings with apulley wheel 104 made fast to the spindle 103 by a drive fit or The hub of-thc wheel vand. the bushing 102 rests upon the other end of the said hub. The cutter 105 is at one end ofarod 106, whose opposite end is reduced at 107-; the main portion of the rod 106 ad This rod 106 fits within the sleeve or spindle 103 and is provided with an adjustable cuttersuspending nut ordevice 109 and with a graduated sleeve 110. The nut 109 is pro vided with an internally threaded longitudinal perforation 111 for engagement with the threaded portion 108 ofthe rod 106 it is also provided with a knurled surface. At one upperjend of the spindle 103. The'nut is provided .with a transverse threaded-hole 114, which opens into or communicates with the threaded hole 111'. A set screw 115' engages with said threaded hole 114 and its end bears against the threaded portion 108 of rod 106 to secure the nut 109 in anyposition justed-on the rod 106. The other end ofth'e nut 109 is reduced .in diameter at 116 and is providedwith a mark the cylinder 116 or index 117 extendinglongitudinally thereof. The graduated sleeve 110 has a knurled cylindrical which are suitable "graduations or marks 119, say ten, numbered from .0 to 9. The sleeve 110: is threaded perforation 12,0 adapted to engage with the threaded portion 108 of the rod .106

it Is also counter-bored at l'20 'to receive ,"it is also provided with a transverse or radial threaded hole 121. A set screw engaging with the perforation 121 and adapted to bear at its end against the threaded portion 108, securely attaches the graduated sleeve 110 to the rod 106.

The head 3 is provided with anupright rod 122 fixed thereto, whose upper end 123 is threaded, as shown; a sleeve 124 fits loosely over the threaded portion 123 and is provided with a flat or leaf-spring 125, preferably fast thereto, which is adapted to bear upon the upper end of the rod 106. couple of nuts 126 and 127, respectively aboveand below the sleeve 124 allow of the adjustment of ,the sleeve 124 longitudinally of the screw 123and secure the sleeve in such adjusted position. By adjusting the sleeve up or down on the rod 122, the desired amount of spring-pressure upon the upper end of rod 106 may be'secured- The function of the spring 125 is to force the point of the revolving pointed end-milling tool or cutter 106 down, before the tracing operation begins, as far=as the nut 109 will allow, and thereafter to maintain the tool in that position, so that during thetracing operation the point of the tool remains at a fixed and invariable distance fromthe axis of shaft 9, without attention on the part of the workman. It is'understood that the spring is to be made powerful enough to accomplish this purpose. The spring may "be swung aside to permit the removal of one cutter and insertion of another, as hereinafter explained, and may then be swung back to working position.

The pulley 104, sleeve 103, nut 109, sleeve 110, and rod 106, are rotated by means of a 'cord orround belt which passes around the pulley 104 and the guide pulleys 128 and 129 at the sides of the head 3, the cord coming from overhead, and being connected with a suitable source of power.

When it is dcsiredto adjust the cutter 105 closer to or farther from the die-blankholder-or the axis 15 of the vise 27, the spring 125 is swung aside; the set screw 115 in nut 109 is loosened, and the sleeve 110 and rod 106 are-rotated together (nut 109 being held stationary-the while) or nut 100 is rotated, the sleeve 110 and rod 106 being held stationary the while, in the direction which will increase or decrease the distance between the nut 109 and the point of the cutter 105, according as itis desired to lower or raise the cutter; as a guide to obtaining accurate adjust1nents,'the mark 117 and the provided with 1 a longitudinal portion and a coned end 118 upon 1 T graduations upon the cone 118 are provided;

in such case, the turning of the rod 106 and i sleeve 110=is continued until the mark lli reaches [the graduation on cone 118 which corresponds to the amount bywhich it is de sired to var-ythe distanceof thepoint of the 011t11611105 from the axis 15 of the vise 27,

-whereupon the said set screw 1155is tightin either dir-ection'probably covering all the ened up and spring 125 is replaced. The distances,throughTfwhich the point of the cutter 105 is adjusted are, relatively speaking, not large3ac01nplete turn of the rod 106 adjustments that will be required after nut, 109 has once beenset. The effect of increasingthe distance between the oint of the i cutter-lO5 andtheaxis (am the axis of shaft 9-) is to increasethe radii of the working-faces of the dies formed. Conversely,

decreasing the dist an ce between the point of v the cutter1105 and'axis -15 (and axis 9) de- 1 creases the radiiof the working-faces of'the Y dies out, The axis ofcutter 105 and rod 106,- produced, passes through the axes of shaft 9' (produced) and shaft 15. The nut 109, in conjunction with the sleeve 103, performs severalfunctions; it forms a support or car rier for the rod 106, and with the tongues @112 and notches 113 forms a clutch for confor rod 106.

necting sleeve 103 with rod 106 and the said nut, 109 also acts'as an adjustable stop -In Figs. 28,29 and 30, are three views, on

i i an enlarged scale,--of matrices or dies pro- 2 and above described. As above pointed out, the matricesor dies shown in thesefigures are intended" for produclng type by duced by the machine shown in Figs. 1 and 1 the rolling irocess. It will now be seen that in cutting t 1e die for the rolling process, it is swung on two axes which differ in their distances from the cutter; consequently the type-face of the die will'be in the exterior surface of a cylindrical ring, which by the the type, It willals-f) be. seen that instead rolling process effects a cylindrical face of ,7 of this face being in the exterior surface of a cylindr cal ring, it may be spherical which it would necessarilybe if the radius of' 'the platen and of the circle in which the'type face of the die swings were equal. In which case, the; two axes 'ofthe die would necessarily :be {at equal'distancesfrom the cutter; that is, theywould intersect each other.

The die-blank 10fshownin Fig; 30 is segmentalortaperin'g and theftop curved surfacethereof formed before the die-cutting is begun,is concentric with thebottom or typeface forming line "130 of the die, and this face isformed or struck, oto say, on the axis of v,The curved bottom lines 131 of the dies shown in Figsy28 and 29,)" roduce thatsurfa'ce of the type which is :to} t the cylindrical surface of the platen (i5 maaav'e the same radius as the platen with enable all portions thereof to bear with the distance from the parts being arranged to which the type are to co'act; which radius is equal to the distance from the axis of-s'haft 9 (produced) to the point of the cutter.

Although preferable, it is not essential that the type shall be formed upon a curve having'the radiusof the platen in connection with which it is to be used, so long asi't is so curved'as to fit the platen in practice, arid su stantial evenness upon the platen. By

reference to Figs. 39 and 40 it will be noted that the two letters upon the t e of a double case typewriter 'are arrange one above another, so that the top of the lower letter is next the bottom of the upper letter, the space between theletters t e extent of the .shift of the writing -machine platen relatively to the type. It

is noted that the curves of the two letters on the type,- although'having e ual radii,

areeccentric to each other, that t ey would intersect if produced, and that the curve of each letter extends from top to bottom, or in are formedv on curves.

Owing to the fact that the point 'of thecutter 105 1s at unequal distances from the axes of shafts 9 and 15, it results that when the die-blank is vibrated about the axis 9, it is out in the arc of a circle lengthwise of the-blank, and when the blank is vibrated about the axis l5'the blank is cut in the arc of a circle crosswise of the blank, or an are at right angles to the first mentioned cut; but inasmuch as the axis 9 1s nearer the epending. upon other words the upright lines of each letter )oint of the cutter, the lengthwise arc is I move' in any desired direction and hence enables the cutter to form or produce any desired figure .or character, as any letter of the alphabet, numeral, punctuation or other mar as well as the right angled cross shown for illustrative purposes.

It will be seen that I have combined a cutter and a'die or work holder, one of said swing on axes at right angles to each other, the relative movements of thecutter and blank holder, wherebythe desired predetermined curves areolotained in the de' ress'ed or intaglio typeface formed inthe 1e, being controlled by sald axes By the abovephrase relative movements" of the cutter and blank holder, I refer particularly to the automatic swin ing movements about said axes which pro uce the desired curvature, as distinguished from erably much larger 7 compared with the 2, thus pressin t -ments which determine the outline of the letter. By this construction the matrices are cut uniformly and automatically upon a predetermined double curvature. The operator may manipulate the tracer to 'vary the outlines of the letters, but not to vary the curvatures upon which the letters are cut.

The 0 eration of. the apparatus is as follows suming that it be desired to form a double-case die for the plus mark shown in Fig.- 28, the guide or pattern plate 90 is placed upon the platform 88 against the pins 89 and stop 99, asshown in Fig. 38, and securely clamped in position by means of two or more clamps 91. The pattern 132 is prefthan the corresponding dieorIdie-figures to be formed on the blank 40; and hence the parts of the machine are proportioned to .greatly reduce the die as pattern. Assuming that .it 1s desired to form the upper or larger die (see Fig. 28) the sleeve'56 is set in say, the

' position shown in Fig. 2 relatively to the slot 55,- also, the die-holder 27 is placed against arm 11 or in the position in the manner above described. The die-blank 40 is secured in the vise by the screw 41 in the manner above described. The tracing-pin 78, which is movable longitudinally in sleeve 74, is placed in the position shown in Fig. 38, to wit, in the center of the cross or plus. mark, which is formed by a couple of intersecting V-shaped grooves. The rod 106 is inserted in the spindle 103 and the spring 125 is -placedover its u per end, as shownin Fig. e cutter 105 down upon the surface of t e die-blank. The cutter is next rotated by means of the described mechanism, the pulley 104 and spindle 103 together with the bushing 102 being lifted slightly, if necessary, for the purpose of causing the tongues 112 to engage with the notches 113 to rotate thecutter. As soonas the cutter, under the force of spring 125, has cut its way into the die-blank as far as the nut 109-w-ill allow it, the tracing-pin 78 is moved by means of the lever 22 along one of the four arms of the pattern 132, the point of the tracing-pin being kept in the bottom of the V-shaped of the vise 27 as shown in Fig. 1)

groove, which it constantly fits by means of the spring 80, which moves the pin outwardly longitudinally of the lever 22. I Assuming that the lever 22 is moved toward the observer in :32, the rock-shaft 9 is rotated upon its axis 'iiut the lever 22 is not moved upon or about its axis 17; it results from this that the end of the vise near- 7 est the observer (which is the left-hand end swings up and the opposite end swings down; the-corresponding groove cut in the die is the lower branch a of the upper or larger *plus mark shown in Fig. 28. When the point of the position shown in Fig; 1 and is secured in such tracing-pin 78 has reached the limit of the pattern in the direction in which it has been moved as described, the said tracing-pin 78 is moved back to bringing theblank back to its first position relatively to cutter 105; and another branch of the cross or plus mark is begun. Let this be the branch opposite the one just formed. In this case, the tracing-pin 78 observer in Fig. 2, and that end of the vise-block 27 next the observer in Fag-2, which is the lefthand end of the vise in g. 1, will swing down and the other end up by the rotation of the rockshaft 9; the cutter will thereupon form the upper branch?) of the upper or larger (lie shown in Fig. 28. After the cut of the said upper branch is complete, the tracing-pin is brought back to the center of the pattern which, of course, brings the center of the upper die shown in Fig. 28 under the cutter and the formation of the cross groove is begun. Assumin that the tracing-pin 78 is moved to the rig t in Fig. 2, along the groove of the pattern, there is no rotation of the shaft 9 ut the lever 22 is moved upon or about its axis 17, and, through the described connections, it moves the link 51 to the left in Fig. 2; and link 51, throughthe arms 67 and 68 and the screws 69 and 70, turns the vise-block 27 upon its axis 15, thus causing the die-blank to move to the left in Fig. 2; the cutter 105 forms in this movement, the right-hand or lateral branch 0 of the upper die shown in Fig. 28. Upon the completion of the cutting of this branch of the die, the tracing-pin 7 S is brought back to yoke 43, the

its starting point, thus the center of the pattern and simultaneously the die-blank is moved to bring the center of the die being formed under the cutter 105. Upon'moving the lever 22 to the left in Fig. 2, the tracing pin still being in the groove of the pattern 132, the link 51 is moved to the right in Fig. 2 and through the described connections swings the die-blank in the same direction; this brings about the formation of the left-hand branch d of the upper or larger die shown in Fig. 28.

The above described operations of the machine assume the use of but one cutter only. In practice, however, I prefer to use two or more cutters to do a given or total amount of cutting, and to take two or more cuts'at the'same piece of work, the purpose being, of course, to avoid puttin an undue amount of work upon a single tool and also to obtain a fine finish by means of a tool doing as little work in the consistent with the fine finish desired.

Hence, the first cut, by means of the cutter 'in the above described operation, would be of a depth less than the depth of the final or complete die. For the second cut, the cutter used for the first cut would be removed and 'a second cutter would be introlast or' finishing operation as is i in placeof thesaid' cutter, the second cutterbeing adjusted to' take a deeper cutthan the one first used. The said second cutter can make thefinishing cut or it may;

merely' -deepen the previous .cut and a third cutter, be-inserted in place of the second cut ter and be used .to give the finishing cut. It 1 is understood, of course, that in making each cut'intheoperation of forming a die the tracing-pin78 and the same fixed pattern 132 are 1 used.

Inca-Se a smaller patternis employed to ob-- t'ain the smaller die, no adjustment of the mechanism from the positions shown ahddescribed is necessary and the operation is sub stantially the same aslabovedescribed. If,

justments are madekT-he screw 86 is re-v moved andtheplatform 88 is moved down- 'ward a distance such that the excursions to and fro. of the tracing-pin 78 in the pattern willbe reducedat the surface of the die-block in the vise to the desired extent, and the. screw 86inserted in a hole opposite theslot 85 and the platform is secured in place. The

slot 85 and screw 86 allow of delicate adjustments of the height of the platform to secure the exact reduction desired." Next the set screw 75 is loosened and thesleeve 7 4 (of the two-part extensible actuating-lever 22 7 4) is slid out of the upper part 22 until the tracingpin 7 8 with'its point at the center of the pat- .tern' and pushed inward relatively to the sleeve 7 4 until pin 79 has risen sufficiently far in the slot resting on the bottom thereof is 77150 permit of free longitudinal motion of the" pin, as the tracer is moved to all parts of the pattern, and the set screw 75 is then tightened upand themachine is ready. The operation of forming the said smaller plus mark is substantially the same as that hereinbefore described. in connection with the formation of the larger ,plus mark shown in Fig. 28, the only difference being that, for the same excursions of the tracer in the pattemthe die-blank makes smaller motions than in the previously described case. v

' The end-milling tool or tapering cutter 105 1 isthree sided and V-shaped or V-pomted at -'.its lower end; that'is, it is substantiallynn inverted, equilateral, triangular pyramid,

and may come t a fine point or the point may be slightly rounded in order to avoid giving too sharp an edge to the working-faces of, the type.

,ThB lines of the finished or printing type faces produced from the matrix equal in thickness the diameter of the extreme point of the cutter. Only a skeletonoutline of the type is generated-in'the matrix by the point of the motion of the vise and die in one direc tion wlthout affecting the amount of its for the production of a set of type'for use in a machine where the movement of the carriage is of an inch for each letter space and it may for making type for'use in'a machine where the carriage moves a greater or a lesser dis-' tance than of an inch for each letter, without, however, making any change in the height of the letters. Provision is made for such variation by means of a sleeve 56 and the. slot 55 hereinbefore described. The closer the pin 63 is to the axis 17 of the lever 22, the less is the throw of the vise about its axis 15, while by moving the slide 56 farther from the axis 17, the greater is the throw of the vise-block 27 about its axis 15. The lines of the dies, formed by the cutter when the vise moves about its axis 15, are those lines which produce the width of a character in the die. width of the character may be varied by varying the motion of the vise about its axis 15.

The method or process of and apparatus and shown in Figs. 28, 29 and 30, will be briefly described. A separate machine is used for this purpose in which a shaft is pro vided having on it a drum and certain disks adapted to have a numberof the dies 40 mounted thereon in such a way that their face of a cylinder or part of a cylinder.

The head 14.2- of each blank 142 is of pris- 1118130 shape, flat or plane on three sides and The convex or rounded on the fourth side. back of the head of the blank is the rounded part while the face is flat and receives the 1m ress ,of the die. The'shank 143 is round an tapered asusual. the-type blanks are mounted has a straight toothed rack which meshes with a toothed gear or pinion rigidly connected with the matrix cylinder.

. ln the operation of forming types the clamp containing the type blanks is reciprooated cylinder containing the dies is rotated, these two parts moving in unison so th at .each type blank is rolled against one of the provided for reciprocating diesl Means are the type blank holder and rotating or oscillating the die cylinder back and forth and for feeding one of these devices toward the other under 'heavy pressure. The result is that the metal of the type blanks is gradually forced into thematrix grooves in the die and this 0 eration is continued until said metal has comp etely taken shape so as to fit exactlyinto said matrix grooves. As the grooves 130 are concentric'with the cylinder and as the type blank moves in a straight line, the part of a type that is formed The grooves ofeach type thus formed lies in the surface of afcylinder having 'a' curvature corresponding to the curvature of the groove 131 of the matrix. It will be recalled that this groove was cut concentrically with the shaft 9 of the and cut in a radius corresponding to the radius of the typewriter platen.

the vise-block 27 may be adjusted accordingly about its axis 15 to bring the point of the cutter to the center of the blank.

In case-blanks'of a shape different from that shown in Fig. 13 are to be used, the jaw 31 is removed from the vise-block 27 and a j awshaped to receive the new style of blank is substituted; the jaw 32may also be replaced by another if necessary.

The modified form of the invention shown in Fig. 38 is intended for the production of dies of the character illustrated in Figs. 31 32 and 33, in'which the die-faces 131 are the sameas in Figs. 28, 29 and 30 and are for the 'sarne' purpose, while the die face 130 is straight and not curved. The type are produced by dro pine or ressin the t e blanks and. the die's one u pon the other, r id the final product is the same as in the rolling process just described. In the machine for producing the dies under consideration, the die-blank holder or vise has directions at right angles to each other, one

motion and the other of which is a rectilineal motion. Those parts of the structure having the same numerals of reference as in the previous figures are the same, and have'the same functions; as the-parts hereinbefore described. Certain parts of the structure, such as the mechanism for driving the cutter, are omitted from Fig. 42 for the sake of clear ness. The die-blanks 4.0 are in the form of solid disks of metal with a longitudinal groove 156 for purposes presently to be described. Thc vise 27 a metal perforated to slide upon the rod 15*. The rod 15 is fixed in the arms 11 and 12 of the cross-head 10; and the cross head 10 is fast upon the rock-shaft or stem 9 The vise 27 is provided with a flange 157 Which rests upon thev top of the cross head 10. The vise is provided with two arms 29 and 30-", which are united by a semi-circular part adapted to form a seat for and to receive the. which rests upon a flat part or seat in the vise above the shaft 15 A latch-piece 158, hinged to the arm provided with a screw 160 passing therethrou h and adapted to engage with a threaded ho e in the arm 30, secures the die-blank 40 in position. The vise 27 is provided with a loc dug and registering rib 161 adapted to co-act withthe groove 156 in the side of the die-blankAO, thus securing that thedie-blank may be-removed and replaced without change of position relatively to the cutter. The shaft or stem 9 is carmotion in two.

consists of a block of ried within a sleeve 162 and is adapted to I move lengthwise thereof. The sleeve 162 is provided with a forked head 163 and the cross head'F IO fast on the shaft 9 is provided with a rectangular arm 164 adapted to stood that the cutter rod 106 is operated in fitbetween the parallel prongs of the fork 163. The setscrew 165, passing through one 'of the prongs of the fork, 163, is adapted to ,co-act with the arm 164 to secure the same immovably between the prongs 163 by these "means the shaft or ste1n9 is compelled to rotate or rock with the shaft or sleeve 1'62 and may be adjusted, together with its attached' parts,-- longitudinally of said sleeve. The sleeve 162 itself fits within a sleeve 166 -which is journaled in the bearing 8 in the i bed 4. The sleeve 166 is provided with a "fork 167 inside the fork 163. At its other end the sleeve 166 is provided with a collar 168 having parallel arms or a fork 169; the said [collar 168 being firmly attached to the sleeve 166. The fork-167 and collar 168 prevent the sleeve 166 from moving endwis'e in its hearing, as they themselves abut against the ends of bed i. The sleeve or shaft 162 projects beyond the sleeve 166 at the front of the machine and is provided with a sleeve 16 fast thereto, and the sleeve 16 is provided with a bent arm 170 which fits between the prongs of. the fork 169, above named; whence it "results that any motion of rotation of either sleeve 162 or 166 is com munic'ated to the other, while the sleeve 162 may'slide lengthwise of the sleeve 166 to a limited-extent, spaces 171 and 171 between. fthe collar 168 and sleeve 16 and between forks 163 and 1.67 being left to provide for i this endwise notionof the sleeve 162. The

The pin 63 in this instance rovid'es a pivotal connection for the rod or linksw with lever 22; at its other end the 45 link is pivoted to the parallel arms 167 by means of thepin 173.

' y Y The vise 27 is provided with a set screw 3 Q 174fby which it'is' clamped to the rod 15?.

The vise is ofale'ngth less than the distance between'the inner surfaces of said arms,thus fproviding for lts ad ustment lengthwlse of the'said rod for the purpose of providing for same blank.

- upper and lower case dies in. one and. the p The adjustments secured by' the arm 164, fork 163, rod 15 and set screws 165 and 174 provide for the'formation of two or more pairs of dies in the same dio block 40, as indicated in Fig. 38.

The operation of the modification illustrated in Fig. 38 is as'follows: It being underthe manner hereinbefore described,and that a die-blank is in position in the vise and a the tracing pin 78 is placed at the center of the pattern 132 and the machine started. The cutter, under the action of spring 125 soon sinks into the die to the depth allowed by its nut 109, and then the tracing-pin 78 is moved along one of the branches of the pattern, let us say, lengthwise of the pattern. This swinging motion of the lever 22 rotates the shaft 9*, sleeve 162,- and sleeve 166 but produces no endwise motion of the sleeve 162 or shaft 9*. The fork 169, arm 170 and the other parts secure that the rear end of the link 51 to wit, that end pivoted on pin 173, shall rotate about the axis of shaft 9 in unison with the front end or that pivoted on the pin 63. The vise 27 is rotated about the axis of the stem 9 and the curved face 131 (see Fig. 31) is that produced by moving the tracing-pin along as described. To produce the cross out, the tracer is brought to the center of the pattern and is then moved across the pattern, and causes the lever 22 to pivot upon the pin 63 and move sleeve 162 and the stem 9 to the rear and then to the front; this causes the cutter to produce the cross cut or groove; the groove produced in this operation corresponds to the straight face .130 of Fig. 32. The die, in this instance, 'may be formed by one, two or three cutters adjusted and used as hereinbefore described. To form the other, say upper, case letter or mark, the vise 27 is adjusted along the rod 15 to abut against arm-11 and is secured in its new position, and the foregoing operations are repeated.

The method of producing enlarged or re duced dies from one and the same pattern is the same in this instanceas in the preceding case or that shown in Figs. 1 and 2. The adjustment of the figure-proportioning sleeve up and down secures the same variations in the results as in the case hereinbefore described.

' It is noted that the blank holder in-both the cases shown has motion in the direction of the length of the shafts 9 and 9*;(and 166) in one case, this motion is a swinging motion about the shaft 1.5 and in the other case lt is a straight or rectilinear motion. It is noted also that the axis of the cutter bar 106 (produced) intersects the axes of shafts 9, (9 and 15 (produced, if necessary.) It is noted further that the end milling tool or cutter 105 works under endwise pressure or has endwise support. and acts or cuts by an end edge or edges and not by a peripheral or'reaming out, being in this respect very similar to twist-drills and carpenter s bits. It is also noted that the axis 15 and the axis of the cutter lie in a plane and that the axis of the shaft 15 swings about the axis of the shaft 9 and in said plane, whence it results'that the angle between the (produced) axis of the cutter 105 and the axis of shaft 15 varies during the operation of the machine.

Heretofore, in producing master punches alinement with the other types in the ma chine, and as such alterations in the type are difiicult to make and require special tools and appliances, as well as the utmost skill of a trained Workman, the process has proved very costly. Particularly was this the case where special types were required for an existing writing machine. Such types were made by hand, without the use of master punches or dies. By my invention this difli--- culty is wholly avoided, and each character in the group is positioned with the utmost accuracy wlthout the necessity of special training or skill on the part of the workman, so that the expense of alining the types on a writing machine is materially reduced. Heretofore, in making s eci'altypes having a plurality of characters t ereon, the usual appliances for making duplicate type faces could not be made available, and the types were necessarily hand-engraved in a laborious manner by a skilled mechanic. To illustrate, in the ordinary Remington writing machine the character it is placed upon the same type with the figure 3, and if it should be desired to substitute a mark for the former, it would be necessary to engrave by hand both the 3 and the 3 upon a single type-blank, to be placed directly in the writing machine. By my invention, a blank is placed in the blankholder, the usual pattern for the figure 3 is placed in the pattern-holder, and the char acter "8 is formed upon the blank in the described manner. Then the pattern is removed, the usual pattern for .8 substituted, the blank shifted, and the character 58 formed thereon, both characters being formed in absolutely correct positionupon the blank, without requiring the services of either a trained mechanic or a skilled engravel.

Of course the invention or improvement is equally well adapted for making dies for single type or characters, and many changes may be made without departing from my 1nvention. The invention may be used for other purposes than making dies for'type. I have shown my invention carried out in the form of a machine for cutting the type faces of matrices, but many of'my improvements are obviously applicable to machmes for cut ting the type faces of master punches used in m ing matrices for writing machine types, especially where it is desired to properly position several characters upon a single punch. By the term type face I mean to include type faces whether formed intaglioin a matrix or in relief on a master punch.

my machine the swinging element has not only a swinging motion upon an axis but also a motion longitudinally of said axis. The last mentioned motion is in one machine a swinging motion, whereby the horizontal lines of the types are curved, but in the other machine, it'is a straight line motion, so that such horizontal lines are given a straight for mation. i

In the machine illustrated at Fig. 2, the point of the cutter is held at an unvarying or set distance'from the main axis or shaft 9, and also in the vertical plane in which the axis 15 swings during the cutting operation. The point of the'cutter works at the intersection of two vertical planes, one whereof passes through the axis 9 and the other whereof passes through the axis 15. The work holder swings with a universal joint motion which is secured by mounting a movable axis crosswise upon a fixed axls. The tracing lever is mounted upon the fixed axis and connected to the movable axis. The

the point of the cutter, the tracing lever be ing mounted upon the axis nearer said cutter. The face of the work lies between the point of the cutter and both of said axes. The skeleton pattern letter, which the tracer constant y fits, is so mounted in the machine that the grooves extending from the top to the matrix by the cutter, that is, the grooves extending along the vertical axis of the letter, are curvedconcentrically with the axis which is nearer the point of the cutter, and the grooves extending across said matrix'letter are curved concentrically with the other axis. In other words thegroove in the pattern letter which extends from the top to the bot tom of said letter is traversed by the tracin in 78 when it moves in a direction'to an from the operator, viewing fig. 2, and when said tracer pin moves to the right andleft in said -view it traverses the crosswise groove of the letter in the attern plate. Means are provided for enab ing a relative straightline shift to be effected between the cutter and the work, so that the cutter may pro duce a lurality of letters upon a single blank. By means of automatically operatdirection of the work-shifting movement are cut on predetermined uniform convex curves. The work holder swings upon an axis 9 which extends at right angles to the direction of said work-shifting movement. The tracing lever mounted upon said axis is face movements of the cutter and 'work a It will beobserved that in bothforms of axes'are arranged at unequal distances from ing devices the grooves. which extend in the the bottom of the skeleton letter grooved in connected to means for effecting relativesurto cause the cutter to penetrate more or less into the work, in order to form the letters on both on that form of the invention and on I What I claim aslnew and desire to secure byLetters-Patent, is:
