To ctZZ whom it may concern.-
Be it known that I, EMIL WERNER, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Typograph-Machines and Attachments; and I do hereby declare the following to be a full, clear, and exact description of the inventio'n,such as will enable others skilled in the art to which it pertains to make and use the same.
My invention relates to improvements in typograph-machines and attachments,to a typograph-machine of that variety wherein type-dies are employed to impress the matrix-blank or matrix from which a stereotypebar or plate may be subsequently cast,and
- my invention oonsists'in certain features of construction and in combination of parts hereinafter described and pointed out in the claims.
In the accompanying drawings, Figure l is a front side elevation of my improved typograph-machine and attachments, a portion of the spacing-mechanism being shown in section, and portions being broken away to reduce the size of the drawing. Fig. 2 is a right hand side elevation of the same in vertical section, portions being shown unsectioned, and portions being broken away to more clearly show the construction and to reduce the size of the drawing. Fig. 3 is an enlarged right hand side elevation of a portion of the machine, more clearly showing certain features in the construction. Fig. 4 is a front side elevation, partly in vertical section, on line 4-4, Fig. 3, showing the type-die-carrier and means employed in reciprocating said carrier, both Vertically and horizontally, the type-dies being removed from the carrier, a portion of gear h beingbroken away to disclose the operative connection of arm 127 of slide 120 with oscillating-shaft D. Fig. 5 is a transverse section of the type-die-carrier on line 55, Fig. 4. Fig. 6'shows a perspective of several type-dies, exhibiting the variations in the size of ribs or noses G employed for actuating the matrix-blank or matrix-feed ing-mechanism. Fig. 7 is. a left-hand side elevation showing, among other things, the means employed for locking the type-diecarrier and paper-carriage of the typewriter mechanism at the desired elevation, and Fig.

Fig. 9 is a front side elevation of the matrixblank or matrix-feedingmechanism, the paper-carriage of the typewriter mechanism and the mechanism that operatively connects said paper-carriage with the matrix-feedingmechanism to effect the horizontal movement ofthe paper-carriage. Fig. 10 shows a plan viewof a portion of the matrix-feeding-mechanisrn and spacing-mechanism with bar R and lower portion of member U of lever U in transverse section. Figs. 11, 12 and 13 are vertical sections of portions of the matrixfeeding-mechanism taken, respectively, on lines 11-1l, 12-12 and 13+13, Fig. 10,1001;- ing in the direction of the arrows. Fig. 14 is an elevation exhibiting the funnel-shaped guide employed in causing the type-die to engage the matrix-blank or matrix exactly at right angles to the surface to be impressed.
Fig. 15 is a top plan in horizontalsection on line 1515, Fig. 14, exhibiting means employed for uniformlyholdin g the matrix-blank or matrix in its passage by the point at which it receives its impression. Fig. 16 is a central vertical section on line 16-16, Fig. 9.
Fig. 17 is a detail showing the spacing-leverin engagement with the top wall of slot R in feed-bar R, the lever being shown in transverse section. Fig. 18 is atop plan, partlyin section on line 18-18, Fig. 2,-showing the driving-pulley and cam-wheel L for actuating the type-die-impressing-plunger, and means employed for operatively connecting and disconnecting said cam-wheel and driving-pulley. Fig. 19 is a vertical section on line 19-- 19, Fig. 2. Fig. 20 is a perspective of the clutch-mechanism employed to operatively connect cam-wheel L with the driving power. Fig. 21 is a rear side elevation of hinged plate Z Fig. 22 is a side elevation, partly in section, of a portion of the typewriter mechanism, somewhat enlarged as compared with corresponding parts in Fig. 2. Fig. 23 is a plan view of a portion of the typewritermechanism with the upright members 55 of the type-lever-bars in transverse section. Fig. 24 is a front side elevation of a portion of the typewriter-mechanism, with bed 47 and a number of type-lever-bars'in section. Fig.
25 is a vertical section on line 25-25, Fig. 2,
looking in the direction of the arrow, the same exhibiting the mechanism employed to operatively connect the type-levers of the typewriter mechanism, with the type -dieactuating-mechanism of the typograph-machine. Fig. 26 is a vertical section of a portion of the typewriter mechanism on line 26-26, Fig. 1, looking in the direction of the arrow. Fig. 27 is a front side elevation of vertically-reciprocating slide 120, parts being broken away to reduce the size of the drawings. Fig. 28 is a section on line 28-2S, Fig. 26, looking in the direction of the arrow.
A represents the bed of the typograph-machine, that is supported in any suitable manner, preferably upon legs A. Bed A, at the front side, is offset downward, asat ct, (see Figs. 1, 2, 3, and 4,) said oifset extending lengthwise of the bed and accommodating the location and operation of the horizontally-reciprocating type-die-carrier. The type-diecarrier comprises two vertical side-members, B and B, arranged a suitable interval apart and extending lengthwise from end to end of the carrier. Members 13 and B are rigidly connected with each other preferably by means of pins or screws, 13 (see Figs. 4: and 5) and effectively braced apart, for instance, by means of sleeves, B mounted on the screws. Members B and B of the type-die-carrier afford bearing for the type'dies, G, that extend transversely of the type-die-carrier and are arranged in two or more horizontal series located the one series above the other. There is preferably a type-die for each numeral, punctuation-mark and letter of the alphabet. Members B and B are, of course, perforated, as at b, to afiord suitable bearing for and accommodate the movement of the type-dies in the performance of their function. In the present instance, there are three horizontal series of horizontal type-dies arranged as hereinbefore indicated. The type-dies bear the type, g, at their forward end or face. (See Fig. 6.) In the normal position of the typedies the face of the type is preferably flush with the outer surface of forward side member B of the tye-die-carrier, with the shank or stock of the type-die protruding at the rear of the rearward side-member B of the carrier. Just forward of member B the typedie is provided with a stop, usuallya pin, G, to limit the rearward movement of the die, and mounted upon the die, between stop G and the rear side of member B of the typedie-carrier, is acoil-spring, G (see Figs. 3 and 7) that is adapted to act in the direction to hold the die rearward. The type-die, at the forward end, has an upwardly or laterally-projecting rib or nose, G for the purpose hereinafter made apparent, and imme diately at the rear of this nose or rib and preferably integral therewith, has a laterallyprojecting flange, or guide, G. Forward sidemember 13 of the type-die-carrier has slots, 1), in open relation with holes I) in said member, to snugly accommodate the passage of of the horizontal travel of the type'die-carrier. U-shaped members, 0, at their upper or free ends, are flanged inwardly, as at C, and the U-shaped members are rigidly connected with each other by means of plates, 0 that are secured, preferably by means of screws, 0 to the faces of inwardly-projecting flanges C of said U-shaped members. Plates 0 constitute the ways or rails of a track endwise of which the, type-die-carrier is adapted to travel as will hereinafter appear, side-members B and B of the type-die-carrier, at or near each end of the same, being provided with an upwardly-extending arm, I) that at its upper end, and outer side, is provided with a wheel, b mounted on the adjacent way or rail.
The bed of the machine is provided with suitable vertical slideways, 0/, for the U- shaped members of the vertically-reciprocab ing frame, and 0 represents caps that prevent the displacement of said members of the vertically-reciprocating frame from their respective slideway, caps 0 being secured to the bed of the machine preferably by means of screws, C (See Figs. 3 and 7.)
The means employed for elevating and lowering the type-die-carrier supporting-frame is preferably as follows:
D (see Figs. 1, 2, 4: and 7) represents ashaft that is located below and extends lengthwise of the bed of the machine, said shaft having bearing in brackets, D, depending from and secured to the bed of the machine.
1) represents rock-arms that are 0peratively mounted ion shaft D and are operatively connected with U-shaped members 0 of the vertically-reciprocating type-die-carrier supporting-frame, the construction being preferably as shown in the figures last referred to, wherein said rock-arms extend forwardly between a pair of rollers,'C secured to the respective U-shaped member of said frame. At the left-hand side of the machine shaft D has operatively mounted thereon a hand-lever, D by manipulating which in the one direction or the other the aforesaid frame and type-die-earrier supported thereby, are elevated or lowered to bring the desired se ries of typedies at the proper elevation relative to the type-die plunging or actuating mechanism hereinafter described.
Suitable locking mechanism for holding the vertically-movable type-die-carrier support ing-frame at the desired elevation, is shown in Figs. 1, 7 and 8, wherein lever D in suitable proximity to its handle D, has pivot- ICC of segmental plate Esecured to the adjacent portion of thebed of the machine. A spring, (1 interposed between lever D and latch d,
and secured at opposite ends,'respectively,'
to said latch and lever, acts inthe direction to retain the latchinengagementwith the respective notch or recess e. The arrangement of parts is such that in the position of lever D shown in Fig. 7, with latch deugaging the lowermost notch or recess of l the series of notches or recesses ea die in the uppermost seriesof type-dies of the type-die-carrier is in position for operation, and by disengaging the latch from said notch or recess and manipulating lever D to bring the latch into engagement with thecentral or uppermost notch or recess 6 the central or lowermost series of type-dies would be brought to the proper elevation relative to the type-die impressingplunger, as would be required if the die selected were in the central or lowermost series of dies.
The means employed for reciprocating the type-die-carrier in a horizontal plane is preferably as follows:c (see Figs. 2, 3, at and 7) represents a slide that is adapted to move endwise between the side-walls of the downward offset a in the bed of the machine. Slide 0, at each end of the type-die-carrier, has
an upwardly-extending member, a, the typedie-carrier being confined between members 0' up and down which it is adapted to slide. To the bottom of slide a are attached the bands, F F, for propelling the slide, and consequently the carrier, in opposite directions respectively. These bands, however, may constitute a single continuous band secured to slide 0, as at F as shown in Fig. 4:. Bands F F are preferably of steel andof course lead in opposite directions, the one band F being attached to and leading over a pulley or wheel,f, at the left-hand side of the machine, and the other band F being attached to and leading over a pulley or wheel f at the opposite side of the machine, wheel or pulley fbeing supported preferably by a depending bracket or hangerf secured to the bottom of the bed of the machine. The downwardly-offset portion of the bed is recessed longitudinally, as at a and suitably slotted, for accommodating the location and operation of the aforesaid means of propelling slide c. Pulley or wheel f is operatively mounted on a shaft, f that extends transversely of the machine and is supported by a depending arm or bracket, secured to the bottom of the bed of the machine. (See Figs. 1,4 and 25.) Shaft f forward of pulley or wheel f,has also operatively mounted thereon a spur-gear, f that meshes with a spur-gear, h, operatively mounted on a shaft, H, that extends transversely of the machine and is located directly below the type-die that is in position for operation. Shaft Hhas bearing in a depending arm or bracket, secured to the supporting-bed. I Upon shaft H,
at the forward endthereof, (see Figs. 1 and 2,) is rigidly mounted an arm, I. -Arm I, at
its upper end, is provided with an index-key, J, the upper end of the arm being perforated, as at I, to accommodate thelocation and operation of saidindex-key. The key is provided with a shoulderior pin J, and perforation I of arm I is enlarged as at 1 forming a shoulder 1 between which and pin or shoulder' J is confined upon the index-key, a coilspring, J that is adapted to act in the direction toretain the index-keyvwithin the respective hole of the series of lateral ,holes It in segmental index-plate, K,that is rigidlysecured to the front of the'bed of the machine. The series of lateral holes k is concentric with the axis ofarm I and the holes, in number, correspond with the number of type-dies in a series of type-dies of the type-die-carrier. Holes 70 are preferably funnel-shaped or flaring outwardly to facilitate the entrance of the index-key. Index-plate K bears letters, marks or characters that the respective holes repre- I sent, that is, bears, in suitable proximity to each hole, letters, marks or characters indicating the type-dies that are adapted to be brought into position for operation when arm I and index-key J are manipulated to cause the latter to enter said hole or perforation.
The one series (and we will suppose the uppermost series) of type-dies bear the capital letter type; another series (and we will suppose the central series) the small letter type,
andthe remaining series the type for numerals, punctuation-marks and other signs or characters. There being only one series of holes in the index-plate, the latter, consequently, not only bears, in the desired proximity to each hole or perforation, the marks, letters or characters required to indicate what typedies are adapted to be brought into proper position upon the engagement of the respectivehole or perforation by the indexkey, but said marks, letters or characters are arranged in such a manner that the operator can at once tell in what series of type-dies the die, that the respective mark, letter or character on the index-plate indicates, is located. If the type-dies bearing the small letter type, are directly below those bearing the capital letter type, as we will suppose, it, of course, would not be necessary to have the index-plate bear both the capital and the small letter, but
one letter, either capital or small, would be sufficient.
Referring to Fig. l of the drawings,the index-plate, adjacent to hole or perforation 7i), for instance, bears the letter m indicating a type-die in the central and uppermost series of type-dies, and directly below said letter is the comma-mark of punctuation indicating that the type-die bearing the comma-type is located in the lowermost series of type-dies.
The type-die-carrier is reciprocated in the one direction or the other to bring the desired type-die of a series of type-dies in position for operation according as arm I bearing indexkey J is manipulated in the one direction or the type-die-carrier is reciprocated in a direction opposite to that in which arm I is moved.
The sizes of gears f h, relative to each other, are preferably such that arm I need be moved but the least distance practicable, being preferably as shown in Fig. 4, wherein the diameter of gear f on shaft f is one-half that of gear h; consequently the index-key is moved only one-half the distance that the type-diecarrier is moved, and the distance apart of the holes or perforations in the index-plate is only one-half the distance apart of the type.-
' dies in a series of type-dies of the type-diecarrier.
As already indicated the type-die-carrier is movable in a vertical plane to bring the series of type-dies, containing the type-die selected for operation, at the proper elevation relative to the type-die-impressing plunger hereinafter described, whereby, in conjunction with the horizontal reciprocation of the type-diecarrier, any type-die in either or any of the series of type-dies can be brought into the proper position.
To prevent end play of the type-die'carrier, a spring, as at 0 (see Fig. 4) is preferably interposed between the one end of one or both side-members of the type-die-carrier and the adjacent upwardly-extending member a of the type-die-carrier slide, said spring being secured to member 0' and acting in the direction to hold the type-die-carrier against member 0 at the opposite end of the carrier.
Plates 0 that as already indicated, constitute the ways or rails of the track of the wheeled type-die-carrier, at their lower edge, extend more or less into corresponding recesses (see Fig. 3) in the top of the adjacent side-members of the type-diecarrier, to guard against and prevent any lateral movement of the upper portion of the type die-carrier and said lower edges of plates 0 are preferably V-shaped as shown to reduce the friction toa minimum. The upper edge of plates or ways 0 is preferably of an inverted V- shape, as shown and engages a corresponding recess in the periphery of the respective wheels or rollers of the type-die-carrier.
Slide 0 of the type-die-carrier, extends, widthwise, beyond the side-members of the type-diecarrier and fits snugly but easilybetween the sidewalls of the downward offset in the bed of the machine.
0 represents bars or plates that extend from end to end of the horizontal travel of the typedie-carrier, the same being secured to the side-wall of the downwardly'olfset in the bed of the machine just above the type-die-carrier slide, and serving asguides to check any tendency of an upward displacement of the type-die-carrier-slide. Hence, it will be observed that by the construction hereinbefore described the type-die-carrier slide is held strictly in line, both horizontally and Vertically.
Z (see Figs. 2 and 18) represents the driving-shaft upon which is operatively mounted the driving-pulley Z, the driving-shaft having bearing in suitable boxes rigid with the supporting bed.
L represents a cam-wheel loosely mounted on the driving-shaft. Cam-wheel L is, however, adapted to be operatively connected with the driving-shaft as will hereinafter appear.
Cam-wheel L is provided with a peripheral cam L that is adapted to engage a roller, M, trunnioned in the rear end of plunger, M, and actuate the latter, plunger M being adapted to reciprocate endwise in plungercase, N, that is rigid with bed A of the machine. The forward portion of plunger M is reduced in size, as shown, forming shoulders, as at m, and the forward end of plunger-case N is correspondingly perforated, as at N, for the passage of said reduced portion of the plunger, the latter having mounted thereon a coil spring m, that is confined between shoulders m and the forward end of the plunger-casing, and adapted to act in the direction to hold the plunger rearward. The plunger is adapted to engage the butt of the shank or stock of the type-dies and force the dies forward to cause the dies to impress the matrix-blank or matrix, the latter represented by on", being conveyed along, forward of the type-die-carrier, by the following mechan1sm:
0 represents a box .(see Figs. 1, 2, 3, 9, 10, 11 and 12) rigidly secured to or integral with a bed A of the machine, and located immediately forward of offset a. Box 0 is open at the ends and top. The matrix-blank or ma trix is fed endwise throughbox O by means that will presently be described, the sides of said box constituting guides for the matrixblank or matrix in the passage of the latter p 1st the impressing-plunger.
P represents an endless-conveyer-belt that leads around a roller or pulley, P, trunnioned in upright posts or suitable supports, P (see Fig. 1) at the right hand end of the machine, and leads over a roller or pulley, P (see Figs. 9 and 11) that is trunnioned in the sides of box 0. The forward trunnion of roller, P extends outside of box 0, and has operatively mounted upon its forward end a spur-gear, P".
The bottom of box 0, in the present instance, is located somewhat above the bed of the machine, but, of course, is cut away, as at 0', (see Fig. 9) to accommodate the passage of belt P and the location of roller P Immediately forward of the type-dye that is in position to be operated upon by impressing-plunger M, rear side of the box is per-v forated or bored vertically, as at 0 (see Fig. 13) and within said perforation or bore is located the lower portion of an upright bar R of the matrix-blank or matrix feedingrnechanism. The lower end of this'bar is inclined or'beveled, downward and forward, as at R, this bevel or incline of the lever being adapted to be engaged by nose or rib G of the type-die, and the rear side of boxO hasa lateral perforation, as at 0 for the entrance and passage of the type-die, said lateral perforation of course being in open relation' with vertical perforation O Perforation O is preferably square and bar R, in cross-section, is of a corresponding shape and size. As shown more clearly in Figs. 13 and 14: of the drawings, lateral perforation O is tapering or funnel-shaped to facilitate the entrance of the typedie, the forward or reduced end of said perforation being just large enough to receive the type-die, and to cause the latter to properly engage and impress the matrixblank or matrix, that is, to cause the impression to be made exactly at right angles to the surface to be impressed. The rear side or wall of box 0 has a slot, as at O in open relation with perforation O to accommodate nose or rib G3 and flange or guide G of the type-die.
I would here remark that it is desirable to have the type-dies operate easily in their bearings but that it is of vast importance to have the dies truly engage the surface of the matrix-blank or matrix to be impressed. I, therefore, employ dies, the butt or rear end of the stock whereof is pointed, convex or reduced in size, as at G and provide the forward end of the impressing-plunger with a corresponding recess, hole or cavity, m adapted to receive or engage said reduced end of the die, the arrangement of parts being such that in conjunction with the reduced end of funnel-shaped guide 0 (that as hereinbefore indicated, is just large enough to receive the die) when said recess or cavity in the forward end of the plunger makes engagement with the rear reduced end of the die, the latter will be properly centered to engage the matrix-blank or matrix exactly at right angles to the surface to be compressed.
Bar R has laterally-extending arms R R (see Fig. 9) that extend in opposite directions and to which are pivotally secured depending links R, that, at their opposite ends, are pivotally connected, with annular disks or rings, 7", loosely mounted upon feed-rollers S and S. Feed-rollers S and S are located, respectively, within box 0 and at opposite sides of, and preferably equidistant from, bar R.
Feed-rollers S and S are trunnioned in the sides of box 0, (see Figs. 11 and 12) annular disks or rings, 7", being mounted upon the respective roller in the rear side or wall of box 0 that is recessed to accommodate the location and operation of said annular disks or rings. The forward trunnion of feed-rollers extends outside of box 0 (see Figs. 9 and 11) and, upon its forward or outer end, 18 operatively mounted a spur-gear S that is in mesh with spur-gear P mounted on the forward trunnion of roller P hereinbefore described.
Annular disks or rings 1', on their inner periphery; are provided with curved grooves or slots, 0", preferably four in number, and gradually reducedin size,\as at W. Within grooves or slots r between the periphery of the respective rollers S S and the opposing wall s of said grooves or slots are located rollers r and between these rollers and the end or grooves or slots 4" opposite to the reduced end of said slots or grooves are located springs 1' that are adapted to act against the respective rollers r in the direction of the reduced end of the slot or groove. To prevent the displacement of rollers r and springs 1"? is provided an annular plate, r secured to annular disk or ring 4" about the respective feed-roller and flush with the inner surface of the rear side of box 0, (see Figs. 9, 11 and 12) and links R are connected, respectively, directly with the respective annular plate or cap r. The operation of this feeding mechanism is as follows:carn-wheel or roller L is operated to cause peripheral cam L thereof to actuate plunger M, the latter in turn'engaging and forcing the type-die forward to impress the matrix-blank or matrix, the latter having been brought into proper position with n box, 0. Previous to the type-die making 1ts1rnpression, however, lateral rib or nose G at the forward end of the die will engage the incline or bevel R at the lower end of bar R, and cause the latter to be elevated. This motion of bar R and its arms B B will through links R, R, be communicated to annular disks or rings, r, the latter being moved in the direction indicated by the arrows, (Fig. 9) causing rollers r located within slots or grooves r of .disks or rings '1', to be wedged into 7 the reduced portion of said grooves 01' slots between the peripheryof the respective feed-rollers S S and the opposing wallof the respective slots or grooves, and causing feed-rollers S S to rotate with the respective encircling disk or ring r.
The periphery of feed-rollers S S is milled, or knurled, as shown, or provided with suitable projections, whereby the rollers, upon being rotated, as aforesaid, will take hold on the matrix-blank or matrix and feed the same onward as required. To cause the taking hold of the matrix-blank or matrix by the feed-rollers to be more positive, I provide a spring, or springs, s, acting downward upon the rollers, (see'Figs. 9 and sa d spring or springs being supported in any suitable manner, and the rollers have preferably an an nular groove, .9, for receiving said spring or springs. The gearing at P S communicates motion from roller S to conveyor-belt P upon which the matrix-blanks will likely be fed in procession to feed-roller S. The matrixblank may, of course, be of any length desired, but should j ust be wide enough to nicely pass between the sides of box 0, the sides of box 0 serving as guides to maintain the matrix-blank or matrix in a straight path. The distance that feed-rollers S S are located, respectively, above the bottom of box 0 and conveyer-belt P (the portion of the latter within box 0 may be said to constitute abottom for this part of said box) relative to the thickness of the matrix-blank, is, of course, such that feed-rollers S S will not fail to take hold of the matrix-blank or matrix, and feed the same as required. To guard against the objection that would be met in case the matrix-blank or matrix did not sufficiently snugly fit between the guides constituted by the sides of box 0, I provide, one or more springs, 0, (see Fig. 15,) to act against the sameedge of the matrix-blank or matrix that 1s designed to receive the work of the typedies, and cause the matrix-blank or matrix to closely hug the forward side of box 0, thereby insuring that the matrix-blank or matrix is always properly, firmly and uniformly held relatively to the typedies, during the impression by the latter.
As shown more clearly in Fig. 15, a recess 0' and spring 0 seated in said recess, are provided at each side of the point at which the impression of the matrix-blank or matrix takes place.
The noses or ribs G of the respective typedies, of course, vary in size, according to the distance it is required to feed the matrixblank or matrix that is to receive the impression of the respective dies. For instance, a die adapted to impress the letter m would necessarily require a rib or nose, G adapted to lift or elevate bar R a greater distance and consequentlycause the connected mechanism to feed the matrix-blank or matrix farther than, for instance, the die adapted toimpress the letter i. In impressing the matrix or matrix-blank with the letters composing a word, to render the work desirable, the impression should be equidistant apart, but as aforesaid, the letter in, for instance, requires more space than the letter i; consequently the variation in the size of ribs or noses G of the respective type-dies to cause the feeding-mechanism to move the matrix or matrix-blank the proper distance. This difference in the size of ribs or noses G of the respective type-dies,will be more readily understood upon reference to Fig. 6 that exhibits, in perspective, six type-dies bearing the type, I, e, n, N, M, and \V. Of these letters or characters, the letters I and e occupy the least space and the letters M and W occupy the most space. It is quite obvious that in order to obtainthe proper adjustment of space or distance between the letters of a word, the matrixblank or matrix must be fed or moved a greater or less distance according to the size of the space occupied by -the letter or character impressed. By providing the type-die with a rib or nose (Sr of the proper size of the most accurate justification is obtained. Cam L having passed plunger M spring m will return the plunger to its normal position, and the pressure being thus removed from the type-die that has just made an impression in the matrix-blank or matrix said type-die will also be returned to its normal position by the action of spring G Bar B and connected annular disks or rings 0', upon the withdrawal or recession of the type-die from the matrix-blank or matrix, are returned to their normal position, partly by the gravity of the parts, and partly (and promptly) by the action of a spring, R (see Figs. 2 and 9) the latter, as shown, being preferably a coil-spring mounted on the upper portion of bar R, the spring being confined upon bar R between the top of lateral arms R and R of the bar and the overhanging end T of a bracket or arm, T, that is secured to the top of the rear side of box 0, end T of said arm or bracket being perforated, as at T to accommodate the vertical movement of bar R, bracket or arm T thus serving as a guide to assist in maintaining the verticality of arm R.
The bed of the machine is of course slotted, as at a, to accommodate the location and operation of cam-wheel or roller L and drivingmechanism. Cam L'-of the cam-wheel has a slight depression, L extending transversely of the periphery of the cam. The office of this slight depression in. the cam will be quite obvious when it is considered that it is desirable to have uniformity in the impression of the matrix by the type-dies. Owing to peculiarities in the construction and shape of certain letters and characters and the consequent peculiarities in the displacement of the material of the matrix-blank or matrix by the dies adapted to impress such letters or characters, with a cam adapted to cause but one impulse to be given to the die there might be difficulty in obtaining uniformity in the impression of the matrix-blank or matrix by the various dies, and I have found that with a slight depression in the cam as just described the prominence of the cam, that immediately follows such depression, causes a fresh or second impulse, as it were, to be given to the die, and affords the die an opportunity to prevent any inequality or irregularityin the impression of the matrix, causing the degree of successive impressions of successive dies to be uniform. The depression in the cam referred to should, of course, not be so great as to cause a disturbance in the feeding-mechanism of the matrix-blank or matrix.
U represents a bent lever that isfulcrumed, as at U, to the bed of the typewriter mechanism hereinafter described. Lever U, at its forward end, terminates above the feedingmechanism of the matrix-blank or matrix in a depending member U that is, however, jointed, as at U. The lower section of depending member U at the lower end there ger, terminates in a depending member U the lower extremity whereof engages an incline m at the forward end of the type-die actuating plunger, the trend of such incline being upward toward its rearend. In the normal position of parts, member U of lever U rests upon the lower end of incline miand roller U rests gently upon the matrix-blank or matrix. As plunger M advances to engage and actuate the type-die to cause the latter to impress the matrix-blank or matrix member U lever U will be elevated by means of the aforesaid incline at the forward end of said plunger, resulting in the depression of roller U at the opposite end of said lever, thereby causing the roller to exerta pressure upon the matrix-blank or matrix at the same time that the latter receives the impression of the type-die, thus firmly holding the matrix-blank or matrix while being impressed by the die. The lower section of memberU of lever U extends through a sleeve U (see Figs. 2, 3 and 9) secured to the top of the forward side of box 0, whereby the verticality of the lower section of member U of lever U is maintained and roller U at all times caused to rest or bear squarely upon the matrixblank or matrix.
A roller, W, (see Figs. 9 and 10) is located within box 0 directly above and transversely 'of the path of the matrix-blank and in advance of feed-roller S, roller W being trunnioned in the sides of box 0 and being adapted to rest and bear upon the matrix-blank and prevent the rear end of the latter from being lifted as it is received and fed by roller S, the trunnions of roller WV being capable of slight vertical movement, however, the sides of box 0 being slotted or grooved for the purpose as at 0 (shown in dotted lines Fig. 9) to accommodate any slight irregularity or inequality in the thickness of the matrix-blank. Springs, as at W, are provided, the same being secured, respectively, to the sides of box 0, with the free ends thereof bearing upon the peripheryof roller W.
Suitable spacing mechanism is provided for causing longer or shorter spaces to be made, for instance, between words, or between characters or letters, as required.
As shown in Figs. 1, 9, 16 and 17, (Figs. 16 and 17 being on the same sheet with Fig. 9,) X represents a bent lever fulcrumed to a suitable support, such, for instance, as a post or standard X rigid with the forward side of box 0. The extremity of the weight arm of lever X extends into a slot R of bar R and is adapted to engage the top wall of said slot (Fig. 17). The power arm of leverX extends through hollow posts or barrels, as atYY' Y that are preferably integral with a plate Y rigidly secured to the bed of the machine. Lever X comprises preferably a flat bar, and upon the power-arm of lever X, within the respective barrels Y Y Y is seated a button, Z, the shank of the latter beingcomparatively long and slotted, as at Z, (see Fig. 16) whereby the bifurcated shank is adapted to straddle leverX, the slot extending preferably to the lower extremity of the shank, but the latter does not extend to the bottom of the respective barrel and the barrel is vertically slotted at opposite sides, as at Y (see Fig. 9) with said slots extending below lever X sufliciently far to enable thedepression of the power-arm of lever X'the distance re-' quired, whereby lever X, by depressing the proper button, will be actuated tolift or elevate bar R and connected matrix-feedlng mechanism and cause the matrix to be fed the space desired, the latter being greater or less according to the distance the button aforesaid is locatedfrom the fulcrum of lever X and according to the proximity of the lower extremity of the shank of the button to the bottom of the respective'barrel; hence, the provision of several buttons, Z, located at different intervals from the fulcrum of lever X and with the shank of the button in closer or less proximity to the bottom of the respective barrel. Referring to Fig.9 of the drawings, button Z, seated ,upon lever X within barrel Y being the button located nearest to the fulcrum of lever X and with the lower extremity of its shank farthest from the bottom of the barrel, is adapted to actuate lever X to cause barRand connected feed-mechanism to feed the matrix a greater distance than buttons Z in barrels, Y, Y which latter buttons are located farther from the fulcrum o1 lever X with the shanks thereof nearer to the bottom of the respective barrels. A spring, as at Z is mounted upon the shank of buttons Z and confined between lever X and bottom of the respective barrel, springs Z being adapted respectively, to return'the respective button to its normal position upon the removal of the pressure upon the button. In case more than one button, Z, is employed, as in the present instance, and as is desirable, slots Y in the sides of the respective barrels, as already indicated, should of course extend sufficiently far below lever X to accommodate the movement of the latter in all cases.
The power-arm of lever X extends in suit- ICC able proximity to the handle of lever D so the camwheel and driving-shaft.
ter the actuation of the impressing-plunger by cam L. Upon driving-shaft Z (see Figs. 2, 18, 19 and 20) is operatively mounted a grooved-wheel, Z thatis located within camwheel L and is preferably integral, as shown, with the driving-pulley Z. \Vithin groove Z in the periphery of wheel Z is located a friction-shoe, Z that is provided with a pin Z projecting outwardly through a lateral hole or perforation L in camwheel L and terminating at its outer end in a head Z hole L being just sufficiently large to snugly receive said pin. By the construction shown it will be observed that a pressure exerted upon the head of pin Z will press shoe Z against the walls of groove Z in wheel Z and cause the cam-wheel to rotate with the driving-pulley. Shoe Z is retained in the position desired by means of a spring Z that is fastened at one end to the cam-wheel, as at Z and the other end terminates in a member Z extending through a hole L provided in the cam-wheel and in open relation with lateral hole L said spring acting in the direction to cause member Z thereof to engage and bear against pin Z thereby, in conjunction with the frictional contact between pin 1* and the surrounding wall of hole L retaining shoe Z in the position desired, in or out of frictional contact with the walls of groove Z of wheel Z as the case may be. Shoe Z of the clutch-mechanism thus constituted,with its members Z Z, is shown detached in Fig. 20.
n represents a fork that is secured, at the side of cam-wheel L opposite to the direction of rotation of said wheel, to any suitable support, such, for instance, as plunger-case N. The arrow indicates the direction of travel of said cam-wheel. Prongs or members n of fork 91 project over the cam-wheel opposite to the direction of the rotation of said wheel, and terminate in close proximity, and are arranged tangentially, to the periphery of said wheel. Fork n is located in such a position relative to the clutch mechanism that is adapted to operatively connect cam-wheel L with the driving-pulley or driving -shaft, members n of the fork are located such a distance apart, and the size of head l of the clutch-mechanism is such, that when the clutch-mechanism arrives at the free end of the fork, pin 1 of said mechanism will pass between members a of the fork, and head Z of the pin will ride upon the fork, releasing shoe Z from frictional contact with wheel Z and resulting in operatively disconnecting Prongs or members n of fork n are cut away or farther separated, as at M, to permit head Z of the clutch-mechanism to pass through the fork, after cam-wheel L has become operatively disconnected from the driving-shaft.
For automatically establishing frictional contact between shoe Z and wheel Z and thereby operatively connecting the cam-wheel with the driving-pulley or driving-shaft, is provided as follows:
Z (see Figs. 2 and 21) represents a stiff plate located at the rear of index K, the same being hinged, as at l, at or near the bottom of the index. Plate Z is adapted to be tilted rearward on its hinges by the engagement therewith of index-key J, and is of such size, relative to the index, that it will be actuated bv the index-key no matter what hole or perfdration in the index-plate is engaged by the index-key. To the upper end of plate 1 is rigidly connected a rod, Z that extends rearward across the machine and terminates at its rear end just outside of the path of head Z of the aforesaid clutch-mechanism. Of course, it is obvious that cam-wheel L,ow1ng to its momentum, will travel some distance further after it has become operatively disconnected from the driving-shaft as hereinbefore described, and the free end of rod Z for the purpose hereinafter made apparent, terminates approximately at such a point relative to the'path of head Z that the latter after becoming released from fork n and before it has come to a stop will come mtg position to be engaged by said rod. Rodl is bent, as required, to avoid interference with other parts of the machine. The ndex-key is of such length, that as said key, 1n the operation of the machine engages any one of the holes in the index it will also engage hinged plate Z and the arrangement of parts such that just as head Z of the clutch-mechanlsm comes opposite the free end of rod Z the latter will be engaged by head Z of the clutchmechanism whereupon said rod will be actuated by means of index-keyJ engaging plate Z and exert a pressure upon saidhead, depressing the latter and causing frictional contact to be established between shoe Z and wheel Z thereby operatively connecting camwheel L with the driving-shaft. Head Z of the clutch-mechanism is elongated in the direction of the circumference of wheel L so that there is no liability of a failure of its coming into engagement with rod Z aforesaid.
Cam-wheel or roller L, in the same circular plane with the clutch-mechanism hereinafter described, is provided with a peripheral cam, L that is sufliciently narrow to pass between prongs or members at of fork n and is adapted to engage rod l and return the same to its normal position, the arrangement of parts being such that said cam will comeinto engagement with rod Z after the latter has actuated the clutch-mechanism to operatively connect the cam-wheel with the driving-shaft. A spring, as at Z is also preferably provided at the rear of plate Z toact in the direction to return the plate to its normal position. Either cam L or spring Z alone, might a11- swer the purpose, but I prefer the employment of both, that the return of plate 1 to its normal position, shall be positively effected and retained in such position, until againactuated by index-key J.
Having thusdescribed theconstruction and operation of the typograph-mechanism, I will Bars 54, at their forward end, terminate, re-- proceed with a description of the means and mechanism employed for operatively connecting with the typograph-mechanism, suitable typewriter mechanism whereby the operator, at all times, is enabled to see a proof of his work. I
Shaft at or near its rear end, has operatively mounted thereon a bevel-gear, f that meshes with bevel gear 33' (see Figs. 4 and 25) operatively mounted on an upright shaft 34 that extends through bedAof the machine and is supported in any suitable manner. Shaft 34, at its upper end, has operatively mounted thereon a bevel-gear, 38, (see Fig.2) that meshes with a bevel-gear, 39, suitably mounted on a shaft, 40, that hassnitable bearing in the upper member, 41, of a bracket or standard, 42, rigidly secured to bed A of the machine. (See Fig.1.) Shaft 40, forward of its forward bearing,has operatively mounted thereon a spur-gear, 43, that meshes with a rack, 44, the latter (see Figs. 2., 22, 23 and 24) extending lengthwise of the machine, and being secured at either end, preferably by means of screws, 45, to a block, 46, that ex tends longitudinally,'and by means of rack 44 aforesaid, is adapted to be slid endwise bed 47 of the typewriter mechanism,bed47 being supported by and preferably integral with legs, 48, that are bolted or rigidly secured to bed A of the machine, bed 47 of the typewriter mechanism of course being located sufficiently far above the typographic mechanism underneath that the latter will not be interfered with. To render the travel of sliding-block 46 as easy as possible, bed 47 is grooved or recessed longitudinally as at 49, and block 46, at suitable intervals, on its under surface is provided with recesses or depressions, 50, that register with the longitudinal groove or recess 49 in bed 47, and fitting nicely between the opposing walls of recesses 50 and 49, and extending transversely of recess 49, are located rollers, 51. Sliding-block 46 also travels in contact with rollers 52 secured to bed 47 at suitable intervals along the sides of block 46. By this construction the travel of block 46 is not only rendered ex ceedingly easy, but comparatively noiseless. Block 46 is provided with a series of transverse grooves or recesses, 53,0n its uppersurface, within which grooves or recesses are nicely, but easily fitted, bars 54, the latter being adapted to slide endwise within said grooves or recesses, that are preferably of such depth as to receive bars 54 with the top surface thereof flush with the top surface of block 46.
spectively, in an upwardly-extending arm or member, 55, to the upper end of which is pivotally connected the power-arm of a curved type-lever, 56, levers 56 being fulcrumed upon a rod, 57, in common, the latter being supported, at either end, by antupwardly extending arm or bracket, 58, rigidly secured to slidingblock, 46, the latter being preferably flanged forwardly at .either end, as'at59, and arms or to work upon rollers as at 63, provided in re- I cesses 64, in the upper and lower surfaces of said bars adjacent cap-plate 61 and slidingblock 46, (see Fig. 22.) The endwise movement of a bar54 rearward causes the typelever operatively connected with said bar to make its imprint on the paper in the papercarriage hereinafter referred to, and this movement of bars 54 is effected by mechanism operatively connected with type-die plunger M of the typographic mechanism, as fol lowsz-Typie-die-plunger M, at the rear end,
(see Figs. 2, 22, and 25) has an upwardly-extending arm or member, 65, that is hollow or bored, as at 66. Type-die plunger-case N, is, of course slotted, as at 67, (see also Fig. 18) to accommodate the location and movement of arm or member 65, but at either side of the latter is provided with an upwardly-projecting and laterally-slotted ear or member 68, the top and rear walls of slots 69 of members 68, sloping downward and rearward, forming an incline as at 70, '(see Fig. 2.) Within the bore of arm or member 65 is located a bolt, 71, the head of the latter, 72,
being adapted to engage a notch, 73, in the lower surface of bar 54 immediately above. The shank of bolt 71, at the rear end, is provided, at either side, witha laterally-projecting pin, 74, that is adapted to ride up and down the sloping or inclined wall of the slot in the respective ear or member 68 of plunger-case N. Arm or member 65, is provided with inwardly-projecting shoulders 75, between which andhead 72 of bolt 71, is confined a spring, 76, preferably a coil-spring as shown mounted upon the shank of bolt7l, said spring acting in the direction to retain the-head of bolt7l in its shot position. Gapplate 61 at the rear end, (see Figs. 2, 22, and 23) has a depending-flange, 77, that is perforated for the passage of pins or rods, 78, that are screwed into the respective bars 54, and upon rods or pins 78, between flange 77, and the respective bars 54, are mounted springs 79,
adapted to act in the direction against bars 54.
There are as many type-levers 56, as there are type-dies in a series of type-dies in the type-'die-carrier of the typographic mechanism; each type-lever is provided with as many type as there are series of type-dies, and the type carried by the type-levers, as to the letters or characters they are adapted to imprint, correspond to the type of those typethe series of type-dies, that the type-lever dies that have the same relative position in p
