SPECIFICATION forming part of Letters Patent No. 423,688, dated March 18, 1.89.

pplication filed June 6, 1889. Serial No. 313,284. (No model.)

To all ZIJ/'tom iv' may concern.-

Be it known that LWVILLIAM JAMES How- ELL, of Flushing, Queens county, New York, have invented a new and useful Improvement in Apparatus for Producing Indented Type- Impressions upon Paper, the., of which the following is a specification.

My invention relates to a machine for pro'- ducing indented typedmpressions upon paper or other material, which impressions may subsequently be used as stereotype-molds.

My invention consists in the construction of the apparatus, as hereinafter more particularly set forth, in which the material which is to form the matrix, and in which the type are to produce their indentations, is disposed in front of an annular type-cylinder, in which cylinder are radial chambers in which the type are placed. The hammer is disposed inside the cylinder, and is actuated to strike and press on the protruding rear end of any one of the type which maybe presented to it. The types are movable longitudinally and are arranged in the same horizontal plane as the hammer,`so that the rotation of the cylinder on its axisbrings any one of the type in place in front of the hammer. Consequentlywhen the hammer delivers its stroke it causes the type in front of it to move longitudinally, so that the type is driven into the paper, wax, or other material which is to form the matrix. This material is then moved a certain distance to the right to space the letters, and the cylinder is again adj ustedso as to bring another type in front of the hammer, and this type is paper corresponding exactly to the letters which would be printed by the type if the faces of the type were inked. The matrix be ing thus formed is removed from the machine, and serves asa mold for stereotyping or electrotyping in metal in the ordinary way.

The important features of my invention are, first, the annular typecylinder in which the movable type are disposed, within whichl cylinder is arranged the hammer which moves Wardly to cause them to produce their impressions; second, the hammer and its associated mechanism, which causes the hammer to strike not a sudden blow on the type, but

to force or press the type into the material of the matrix for a measured distance ;r third, the construction of the hammer mechanism so that it shall act positively. on the ham mer and operate with greatest force when the hammer approaches the end of its inward stroke,

" and hence has forced the type most deeply into the matrix; fourth, the lmechanism whereby a rotary type-wheel is turned in differentpositions by the oscillation or vibration of a pivoted bar or plate operated upon by Wedges or cams placed at different distances from the center of oscillation, said cams being associated With the finger-keys; fifth, the construction whereby power from an outside source is caused to actuate the various mechanisms embodied, so as `to reduce the manual labor of the operator practically to such as is necessary only for the adjustment of the parts and the regulation ofthe time of applying the power; sixth, the novel construction of the letter-spacing mechanism ;l seventh, the various novel combinations and sub-combinations of mechanism, all substantially as hereinafter set forth. Y

In the accompanying drawings, Figure lis a vertical section of the machine on the line X X of Fig. 2. Fig. 2 is a plan view.v Fig. 8 is an end elevation of the machine, looking toward the rear side of the movable carriage. the same line as Fig, l, and showing corresponding parts on a larger scale. In Figs. l and-4 the'iinger-keys are shown in a different position, as will be more fully set forth hereafter in this specification. Fig. 5 is a detailed view,` showing the mechanism arranged on the-rearside of the carriage for operating the spacing device. Fig. 6 is a side view of the same mechanism. Fig. 7 is a sectional view, on the same line as in Fig. 1, of the Fig. l is Aa sectional View taken on mechanism for operating the type-striking hammer, the said mechanism being shown on an enlarged scale, and the link-levers being in a different position from that indicated in Fig. l.

Fig. 19 is a section through the support '50, just above the bolt 85.

Similar numbers of reference indicate like arts. I will [irst describe the mechanism whereby on the'pressurerof a finger-key a movable type is adjusted in proper'place in front of the material upon which the character is to be impressed, and which mechanism, by continuing its operation, causes the type to be struck by the hammer and moved outwardly, so as to produce said impression. ,1 is the tablev or bed ofthe' machine, on whichare two standards 2. Between the standards 2 extends a curved fulcrum-bar 3, (dottedlines, Fig. 2,) which passes through holes in the keys 4. It will therefore be understood that when any one of the ten keys 4 is struck by the tnger in the ordinary manner of thetypewriter key it will vibrate on its pivot-bar 3. Said keys are separated by washers (indicated at 5.) y

The casing of the machine is formed in two parts, the lower part 6 being secured directly tothe bed 1 and the upper part 7 resting upon the-part 6 and also upon the two standards 8,'Fig. 1. The part 7 is secured in place' by the three screws i), which enter the lowercasing 6, and also by the screws 10,

' which enter the ends ot the standards 8. By

removing these screws the upper casing 7 can be separated from the lower casing, so as to allow of access tothe interior mechanism.

The casing 6 is open in front, as shown at 11, Figs. 1 and 4, so that the keys may extend through it. keys 4 is a cam .projection 12, and also a pin 13. The side of the projection 12 nearestethe pin is beveled or inclined, s0 as to form a.

cam-surface. Pivoted at its middle to a lstandard 14, rising from the bed l, is a semicircular plate or bar 15, to which are attached cords 17, which cords are connected to the ends of springs 18, inclosed in suitable casings, Fig. 2. It will be understood that when the curved plate I15 is vibrated horizontally j on its central pivot it will be opposed by the action of one or otherspring 18, and that the tendency of thesprings will be to bring the plate always back again to its original position. T he extremities of the curved plate 15 Fig. 17 `is a face.

Fig. 18 shows they On the under side of each of the tends underneath all vthe keys and'which is supported upon rods 22, whichV rods rise from another curved plate 23. Plate 23 is supported on a series of arms 24, (dotted lines, Fig. 13,) which radiate from the lever-arm 25, which lever-arm is pivoted at 26 to a bracket 27, which extends downward from the frame 1. Consequently when the lower edge of the projection 12 meets the plate 21 it forces that plate, and hence the plate 23, downward, and so causes the lever 25 to vibrate on its pivot 26.

At the end of the-lever 25, Fig. 7, is a vslotted link 28, into which enters the pin 2 9 on the dog 30. The dog 30 is made in two parts, as shown in sectional view, Fig. 8, and from each part projects a pin or roller `31, each of which pins enters a camfgroove 32, formed upon the faces or kbrackets 33 34.

35 is a bent lever pivoted to the bracket 36, which depends from the bed 1. The downwardly-bent end of lever 35 is connected by a spiral spring 35* to a pin which extends between the lower extremities of the parts ot' the dog 30. The lever 35 is pivoted between the upperfaces of the dogs' 30, and also o n the same pivot between said dogs is alever37. In the extremity of the lever 37 is al slot 37*, through which passes a pivot-pin which connects said lever with the hammer-rod 38.

Each of the dogs`30is provided with a shoul-` der or step 39, which is suitably placed so as to be eng-aged by the teeth of therwheel 40. The wheel 40 is supported -on the shaft 41, vwhich extends between suitable bearings 41*, Fig. 3, depending lfrom the bed 1. On sai'd sha-ft is a pulley 42, by .means of which mo# 4tion is communicated to said shaft by a belt 43 from an electric motor or other suitable source of power, the, pulley, and hence the wheel 40, beingrotated in the directionv of the arrow. The wh eel 40 isloose upon the shaft 41, but is provided with a segmental-opening 44, Fig. 7, in which enters a' projection 45 from the shaft. The projection 45 meets the end of the opening, Land so carries the wheel around with it. l Betweenpthe projection 45 and the end'vot` the opening in the wheel is interposed a spiral spring 46. The obj ect of this spiral springis to act as a cushion, so as to prevent too sud- IIO den movement cfthe Wheel 40 and possible A disarrangement of the mechanism. Beneath under the bar 21; but when the key is de` pressed the effect of the rollers 136 lwith the bent rod 135, which is carried through them downwardly, is to move the bar 134 to the left of thedrawing, so that the hook 138 on the key engages with said bar 134, as shown in Fig. 4.

The operation of theapparatus so far described will now be explained. Vlien the key 4 is pressed down, v the straight lower end of the projection 12 first strikes the bar 21, thereby forcing downward the plate 23 and raising ,the slotted link at the end of the arm 25.L The effect of the raising of the slotted link'28 is to cause the rollers 31 and the dog 30 to traverse the cam-'groove 32, so that -thev toe or shoulder 39 on the dog 30 is brought intopo` sition to be acted upon by theteethof the wheel 40. The effect of throwing forward the dog, so las to bring its shoulder 39 into posi- ISO tion for engagement, is also to'gcarry upward the levers 35 and 37; but the lever 37, by reason of the slot 37* therein, then moves over its pivot-pin in the end of the hammer-lever 43S, so that during this motion'of the dog noi movement is communicated to the hammerlever. Consequently the only resista-nce to the downward pressure of the key is the inertia and friction of the few partslnecessary -to be moved to bring the vdog into proper po-Y sition to be acted uponv by the wheel As already explained, the descent of the plate 21, i

forcing down the bar 23, throws the lockingplate 134 to the left, so that it engages'with the hook 3S on the projection 12` under the key 4; hence by the'time the wheel 40 beginsto act on the shoulder 39 to carry it up the'key 4 is locked to the' plate 134, and-hence the rotation of the wheel, raising thefleverarm 25, pullsdown the 'key 4 still farther; The further `operation ofthe machine is then vdone bythe outside source of. power acting upon the wheel 40, and it will therefore be understood that the manual work of 'the 0perator consists simply in 'forcing down the key suiciently far to throw the shoulder; 39

on'the dog 30 into position to beacted upon by the wheel 40, and simultaneously to cause alocking of the key to the levers, which are now'to be'movedA by the wheel. The wheel in rotating carries up the dog to the .upper arch'of thecam-grooye 32, and in so doing brings the levers and 37 into "a horizontal position, as shown in Fig. 7 but beforethe lever 35 reaches this horizontal-position the end of its' slot 37* will meet the pin in the end of the hammer-lever 38 and carry the hammer-rod 3S to the right of Fig. 4 against the action of the spring 383, attached to said rod.-` Inasin'uch as said rod is pivoted at 47, its Vupper end, which carries the hainmer 4S, is brought into contact with one of is, asalready explained, raising the lever 2,5, andhence moving down the plate 23, to which the key has been locked( Consequently as the key goes down the' front inclined edge of the projection 12 meets the in`- ner side or edge of the Acurved plate l5 andV causes'that plate tovibfrate on its`central pivot.-

If the key which is pressed downis'` located just on one side of the central pivot,"it will be obvious that the'plat-e 15 willbe displaced or caused to oscillate over agreater arc than when it is 'acted upon by a similarly-arranged key placed at a greater distance from the pivot; hen'ce'no two' of vthev keys 4 will swing the plate 15 over the same distance in the arc. if

It will be` understood', however,'.that the keys located on opposite Asides of the pivot 14 will f I causethe plate15 to 'oscillate in the rela'- tively opposite directions. l By the greater or less movementof the plate l5 the typecylinder -is rotated so as to bring the type linto position so as to be struck 'by thehammer. How this'is dn'e will be described far-k Meanwhile attention is now calledk ther on.

to the projection o r pin 13,' which projects.-

downward from the. key 4. This pin, when Vthe key 4 is pressed down, enters a hole'(one of a series) in the plate 15,"which is suitably disposed-to receive it, as shown in Fig. 4.- It

doesfnot reach this hole until after the plate 15 has been moved by the projection 12, Of

course when the pin 13 'enters the hole inplate 15 plate 15 can no longer oscillate on its pivot,

and therefore the object of the pin 13 is to prev'ent't'oo much oscillation of the plate 15, j

because if'the-key were suddenly drawndown the plate v15 might in that case swing a little beyond its proper point. lf' as soon as the plate 15 is adjusted the pin 13 enters the open`4` ing and-locks it, it will be obviousthat no furihermotion'of plate 15 can ensue. v

Y I will nowrefer to the'typ'e mechanism.`

Extending up from the bed 1 is a tube 49, and surrounding this is loose tube or sleeve 50.

Uponisaid tube 50 is a chain or sprocket wheel'5l;` The sprocket-chain 52 passes over fixed pulleys 53, (dotted lines, Fig. 12, and dotted lines, Fig. 2,) and is connectedto the ends of the' swinging bar 15 bymeans of a screw-v bolt 5333'- as shown in Fig. 16. Y In order to prevent slacking of the chain when the bar 15 oscillates, Iprovide an arc-shapedrplate 54,

which is carried by said plate 15 by'fdo'wnwardly'- depending arms 55, 15.2 This curved-bar 54 rests upon a roller '56, which is supported o'n the bed l. The ends -ot' the chain-,after passing'- around the pulleys'53, extend over the periphery of this curved bar to the end of bar 15. It will be understood,

therefore, that when the bar 15 i's'oscilla'ted on its central pivot it rotates the sleeve' 50, and that the extent of rota-tionof the sleeve 50 will be in either direction proportional to the arc swungJover by the bar 15.

57 is thetype-cylinder shown in partial j horizontal section in Fig.' 10'and in elevation in Fig. 11. This consistsof an annular piece plate 60, is a spiral spring 62.

of metal or hard rubber'provid-ed with a vse# ries of compartments radially arranged.V Each `chamber or compartment is -ofsuitable size' Ato contain one of. the type 58, Fig. 10. On each type is formed a shoulder 61 of suitable size knearly to iill up the cross-section of t-his compartment and move freely therein. The inner end of the .type projects through an opening in the rear of the compartment and into'the central space 59. The front end of` the compartment is closed by a plate 60, of

metal, 4which enters a recess in the cylinder.

The outer ends of the types pass through'said the hammer-head, and therefore itwill be obvious that by rotating the cylinder 57 any type jmay be 'brought in front of the hammer,

so as to be acted uponthereby.

To recapitulate brieiiy, therefore, the operationY of the mechanism so f ar described, when a key 4 is pressed down it iirst throws ytheishoulder ot the dog 30 into position to bev acted upon by the wheel 40; or, in other.`

words, arranges matters sok that the power applied to the machine may go on and do the which is pivoted to a bracket 33 at 92.

work. e down farther, and the keyin golng down The wheel in rotating pulls the key farther swings the plate 15, and thus rotates the type-cylinder 57, so that a certain 'type corresponding to the key which is pressed is brought in front of the hammer.

Then the wheel, still operating, actuates the hammer'to strike the type, and thus causing the type to impress itself upon the paper or other material disposed to receive it, and, lastly, the dog is retractedfrom yengagement with the g wheel, the lever 25 descends, the key 4is unlocked and returns to its normal'position, and the dog resumes its original placeready to be thrown into engagement with the wheel again when a key is once more pressed.

I will now describe the spacing mechanism, i whereby the material to be indented is caused l to move in front ofv the type, so that the indentations may be disposed thereon in the proper order to `'produce the desired words, zc. l.Extending Idownward from the upper case 7 is a bracket 66, Fig. 4, to which is pivoted a swinging bail 67,*which extends over the ends of the keys 4, sothat by pressingk any one of said keys the bail 67 maybe swung on its pivot. Connected to said bail is a rod 68, which works the spacing mechanism.y rPhe rod 6,8 is secured to a leverr9, e

V- end 'of the-rod 69 is forked, andv in the fork is received the lower extremity of a bar 94, Fig. 3. Upon one side ofsaid bar are formed rackteeth, Fig. 5, which engage with a pinion 95,

which is supported on the rear side of the carriage 96 in a bracket' 97. (See Figs.`1, 3,

and 5.) 98 is the pinion-shaft, whichl terminates'in a gear 99, this gearbeing placed just inside the rear face of the supporting-carriage 96, Fig. 1. Surrounding said pinionshaft is a spring, (not shown, but inclosed in' lthe cylindrical casing 97i, Fig. 6,) which acts upon a fixed abutment on the bracket 97, and also on the pinion-shaft is a ratchet 100, (dotted lines, Fig. 5,) which acts upon a pawl 101,

which pawl acts upon the pinion 95. The op eration of this spring is to cause the pinion nor-V mally to turn in one direction. 102 is a bentbar also havin g on its edge rack-teeth adapted to en gage with pinion 95, and provided on its horizontal portion with two rollers 103 on Iopposite sides-ot' the bar 94. The bar 102 is pivoted at 104. Extending downward from the upper flange of the carriage 96 are two brackets 105 and 106, to which are pivoted, levers 107 'i 108, which carry at their ends rollersJ which bear against opposite sides of the bar`94. Y .90

The spiral spring extends from the pivoted lever 108 tothe hook end of the bracket' 106. from the pivoted lever 107 lto -the upper Iiange of the carriage 96. 105 and 106 are shoulders 105* and 106i, for limiting the movements of the arms 107 and 108 when said arms are retractedl byv the springs 109 and 110. As the rod 94moves downward, the tendency of thelever 108,V

'acted upon. by spring 110, is to ycrowd the rod 94 against the pinion 95, and so cause en- A similar spiral spring 109 extendsl Upon the brackets,k Y l i roo fl 'gagement of the rack-teeth of rod 94 with the teeth of pinion 95, and simultaneously it moves rod 102, so-as to throw that rod to the left and out of engagement withl the: pinion. At the same time the lever 107 drops down (see Figr) and allows of this inward swing- I from the pinion 95. At .the same time the rod 94 draws the rod 102 into engagement with the pinion,- and thus the pinion is locked in place until the rod 94 makes another downstroke, when the foregoing operation is repeated. The carriage 96 is provided with a dovetail slide 111, which enters ways 112 on the bed or table 1. Extending upward from said carriage is a fixed nut 113, Fig. 1; also extending upward from the table 1 are'brackets 114, in which brackets is journaled a screw 115,which is turned by the hand-wheel 116. By turning the hand-wheel 116 the carriage 96 may be caused to slide in its ways, and so brought nearer to or farther from the type-cylinder 57. On top of the bracket 114 is fasteneda fixed pointer 117, and I may lay oft' the rim of the hand-wheel 116 in any'convenient divisions, so that the pointer 117 will show the extent to which the wheel has been IIE f turned, and thus the extent of movement of the carriage may be nicely graduated and observed.

I will now describe the device which holds the paper or other material uponv which the type a're to produce their impressions. The

front view of this device is shown in Fig. 13.'

118, 119 120 are the vertical mem-bers and transverse 4member of a frame of light thin metal, such as steel. In the lower portion of this frame is journaled a roller 121. About half-way up said frame is the rack-bar 122, and, finally, on the upper end of the members 118 119 is journaled another roller 123, which It will be understood7 therefore, that the paper-frame is held between the roller 129 .and

-the carriage 96, and that it is'supported upon the roller 127, which rests .upon the rail 128. The roller 121 enters and freely moves in a circular chamber130in the carriage 96. The rackbar 122 enters and freely moves in a similar but smaller chamber 131, extending across the face of the carriage 96. Therefore the frame 118 119- 120 is free to slide' longitudinally rosswise the. face of the carriage 96.I` The inclosing-wall of 1 the chamber 131, which receives the rack-bar 122, is slotted on its under side, so that the pinion 99 may project therein and engage with the rack-bar122. A handle or knob 132 `is .provided for convenience in turning the roller 123. I

The spacing-key 133, Fig. 2, is a simple lever notprovided with the downward proj ection 12. It is pivoted upon the bar3. Its rear end acts upon the bail 67 to raise the rod 68, and thus throughV the lever 69 to operate the bar 94 in the manner already described. c It is ofcourse important that the type-'cyllnder should not be free to oscillate or turn loosely on its `center at all times, but that it should be held in position firmly, except just when it is rotated to set a type in front of the hammer. I therefore provide a locking mechanism, which normally prevents the sleeve 50 from rotating, but which is released when a key is pusheddown. Securedv to the rod 68 1s a spring toe or stop S3, whichacts upon the pivoted bell-crank lever S4, and the lever VS4 operates a sliding spring-boltS. In the sleeve 50 is a slot which receives said bolt, so that when the bolt is in the slot the sleeve 50 is locked .and prevented from turning.

rlghe arrangement of the spring toe'or stop 83 upon the rod 68 is such that Ithe ,lever 34 is acted upon to withdraw the bolt, and thus leave Ythe sleeve 50, and -hence the cylinder 57, free to turn just before the key4 -commences to act 011 the swinging plate 15.`

Any one skilled in the` art will readily understandthat the various motions heretofore described are to be so timed, and hencethe mechanism is to be so adj usted and arranged, that the various operations will'follow in their proper order, and this order recapitulated is as follows: First, a key is pressed down, throwing the dog into position to be engaged by the wheel and simultaneously locking the key tol the wheel through the intermediate devices, so that the key receives motion fromthe wheel; second, asl the key is drawn down it operates the lever S4 and releases the typecylinder, so that the latter is now free to be turned 5 third, as the key continues to go down it vibrat-es the plate 15, and so sets the typecylinder in position `to bring the type corresponding to that key in the path of the hammer; fourth, the pin 13 on the key then en? ters a hole in the plate 15 and locks Jthat plate from further motion, and by this time the toe S3 has passed t-he bell-crank lever 84 and the spring-bolt 85 has been again thrown by the action of its spring into the slot in the sleeve 50, thus once` more locking the cylinder in place; iifth,by this time the lever 37 is acting upon the hammer to force it against the type, causing said type to make its indentation; sixth, the. key 4 now raises lthe bail 67 sufliciently to operate the spacing mechanism; seventh, the dog now passing the arch of the cam-groove 32 .goes back to-its normal position, the key 4 is released, and the partsresume their condition as at starting. I haveshown in the type-cylinder only ten type 5 but of course it will be understood that I may arrange more type in said cylinder, so as to .increase the number of characters.` A machine of ten type, however-each'one representing one of the numerical digits-hasa special utility for the preparation of stereotypeingmolds for arithmetical tables and like work. A

Itis to be distinctly understood that the drawings forming` part hereof are not working drawings, nor are they drawn to any deii- IOO IIO

arranged to bring about the proper timing and co-ordination of the movements. The sleeve 63 of cylinder57 simply surrounds the tubular support 50, so that the said cylinder and sleeve are easily detachablefromthe tube. It is desirable in practice to provide several cylinders 57, having different type, all interchangeable upon the support 50. In this way the capacity of the machine for imprinting i 57, and gearing between said plate and said cylinder, substantially as described. z 5 y 3.
