To all whom t may @or/cern." y
don, England,` have invented certain new and useful- Improvements Vin Type-Writing Ma-4 chines, of which the following is a specification.
This invention relates to type-Writers *and has for its object to simplify and reduce the cost of their construction and will be best understood by referencev to the accompanying drawings, in Whichl Figure 1 is a plan of a type-writer constructed according to this invention, parts of which, notnecessary for a clear understanding of the invention, are for the'sake of clearness omitted from this view. Fig. 2 a'trans-` verse section on the crooked line 2-2 lof Fig. l. Fig. 3 is a longitudinal section on the crooked line 3 3 of Fig. 2. Fig. 4 is an elevation of Vsome of the type-levers as seen'when looking in the direction of arrow 4 of Fig. 1. Fig. 5 is an end elevation showing the paper feeding device. Fig. 'is a side elevation of one of the key-levers andits spring and a portion of the base-plate shown in section. Fig
7 is a transverse section of the 4inkin'g-p'ad drawn to an enlarged scale.
Like letters indicate like parts throughout the drawings. i I
A is the base-plate which may be supported on three or-more legs 0r standards'-A with l blocks of. rubberor equivalent materiallet into their lower ends' in the usualv manner..
B is the segmental plate to which are attached the brackets C in which the typede-` v absorbent material e to hold the ink, faced with muslin, silk or other equivalent material f e2 upon which the type-heads rest and through which the ink passes.
According to the construction of the machine the pad may be modilied but Itind it lconvenient to place the pad in the hollow arc 5 5 vE and to hold the edg'es'of the muslin` orother covering e2 with Wires or. a' frame e3,'which may be sprung into the arc. To supply the pad with ink this may be eectedlby vbrushing it overthe outersurfacel of the covering 6o c? or, by removing the Wires c3 and covering c2 and applying it directly to the absorbent material e. This form ot'- pad serves efliciently` to 'ink the type while keeping them out of contact with the feltwhich is a great desideratum because it is found that Whereever the type is allowed to come into Vdirect contact with felt or other similar absorbent .inking material the type becomes clogged with fibers Whereas according to this `inven- 7a ,tion the covering c2 is of such material or texture that it will 'allow of the ink passing through it but not any fibers of the absorbent material.
F are the key-levers which radiate from a common center and eachof which, .as shown in Fig. 6, is provided with a bearing point f which forms the pivot of the' key-lever and is located in a conical recess a formed in the under side of the base-plate A. The recess a 8o of'each key-lever may be'independent ofthe others or all the ybearing points f may be l0- cated in one long grooveof an angular shape in transverse section. Each key-lever is connected with oneof the type-levers by a link f', passing through the plate A, andvpin fgin the ordinary Well-known manner, and each key-leveris'moreover guided near its front end in a yslotted segmental plate A2 or between wires or equivalent guides.
G is a bar rigidly mounted in brackets G secured to the under side or forming part of the base-plate'A and on `which bar G is piv-A oted the back end ofthe spacing lever-G2, which is preferably forked at its rear endl as shown in Fig. 3, so as to passion each'sid of the escapement mechanism. The'fro'nft'f'end`l of G2 is provided with the usual finger plate" g.l Each key-lever F,as`also thespac'i'ng lever G2, is provided with a spring H (preferably roo formed of wire with a turn in il) for raising it toits normal position after it has been depressed by the operator, this spring being Se.
vcured to the under side of the base plate A;
or any other suitable form of spring may be employed for this purpose. The bar G also forms the pivot of the leverI the front end of which is provided with the segmental plate I which, with the lever I, is hereinafter referred to as the anchor I, and which segmental plate I extends beneath the whole of the key-levers F and spacing lever G so that by the depression of any of these keys or the spacing lever, the anchor I may also be depressed. The anchor I is pivoted by a piu j to a plate J the upper end of which carries the dogs or knifeedges of the escapement mechanism as hereinafter more particularly described.
Each type-lever D at its upper end has pivoted to it a shoe K to which is rigidly secured the type-head k which may have formed upon it three (as'shown) or more or less type-faces it k2 7c3 these type-heads k being so arranged as Aregards the angle which they form to the 'respective shoes K that upon their depression for imprinting a letter they wllalways reach `the platen with the type-faces present-ed in the proper position; this variation of the angle of the type-head 7c to the shoe K is most clearly `shown in Fig. 4:. Each shoe K is connected by a link L to the end C of a jointpiece C C2 pivoted on a pin c in the appropriate bracket C. Each bracket C is provided with a spring c which bears upon the tail C2 of the joint-piece C C2, and is adapted to yield sufficiently to allow of the movement of the 'joint-piece C C2 necessary for enabling thesh'oe 'K and lever D to move as one piece after the shoe has fully engaged the lever D (as Shown in dotted lines in the third `position in Fig. 2) at which time something must yield, and I prefer this to be the link pivot, though a spring link would accomplish the same purpose. The object ofthis temporary uniting of the shoe K with the lever D is to prevent the blurring of the impression upon the paper "which can only be satisfactorily effected by the type striking and leaving the paper after making the impression without the 'type partaking of the turning movement whichit undergoes at other parts of its stroke.
Mis `the paper carriage in which the platen M is mounted in the usual manner so that it may be rotated by hand, for line spacing, by means of the milled head M2, Ms being the pawl whichby engaging with the tooth wheel M4 oiers sufficient friction to prevent the platen being accidentally rotated.
N is the paper guide pivoted in any convenient manner to the paper carriage as for example on the spindle N of the roller N 2 which is `mounted in the frame of the paper carriage so platen; the upper surface of N may have en- `to slide in the direction from back to frontof the machine or vice versa, in guides p secured to the base-plate A as shown most clearly in Fig. 3. By the provision of a slotted tube such as O for guiding thepaper carriage said paper carriage is capable of traveling to an extent considerably greater than where no such guide is provided because no obstacle is presented to the passage of the arms m along the slot orlongitudinal passage of the guide; `consequently were it not for other `obstacles such as the arms S and escapement mechanism the carriage might readilybe slipped endwise off the machine, but should this be necessary for repairing purposes or in order to replacethe paper carriage by a longer or `shorter one,"it may readily be effected by detaching the obstructing parts. The slotted tube O may be made of any desired length and servesequally well to support a long or short paper carriage either of which may be used quite irrespective of 'the general dimensions of the rest of the machine excepting the escapeinent rack the length of which would varywiththe length ofthe paper carriage.
The front part of the frame P has secured to it standards Q -onthe top of which is'mounted the rail Q over which travelstheroller m2 pivoted to the arm mi extending downward from the rod m4 secured at its end's'in theend plates of the paper carriage Onthe rod m4 are adj ustably mounted the paper guides m5 m6 the upper end ofthe latter of which is pointed as shown in Figs. 1 and 3'to serve for indicating the position on'the paperatwhich it is desired that the bell R should be struck or sounded, the block m7 of the paperguide m6 for this purpose being providedwith the pivoted bell-trip m8 and stop pin mi the nformer of which by abutting against thearm r secured to the spindle lr" of the bell-hammer r2 causes said hammer to be depressed so that when the trip m8 passes beyond' the arm fr thel hammer r2 will be immediately raised by the spring r3 encircling its spindle fr andwill strike the bell R. The belltrip m8 is so arrangedthat in its return movement on coming into contact with the arm r it will be turned on its pivot to enable it to pass over said arm Without operating it. By reason of the leverage exerted through the bell-trip m8 and pin fm, the block m7 is clamped upon the rod m4 at the time it is pressed against the bell-arm r for sounding the bell.
At the under side of the paper carriage M 'andthe other s at its lower edgeand both facing in the same direction; or instead of one bar S with two sets of rack teeth formed upon it, each set of teeth s s may be on av separate bar. The before described plate J which is guided so that it may freely recip-Y frocate in a vertical direction has secured to pression of a key-leveror the spacing lever.
The plate J has also hinged to it a bracket or framej2 carrying atits upper. part a dog orv knife-edgejs. The frame 7'2 is pivoted toJ at j* and is provided at its lower part with a spring 7'5 which tendsk always to throw the bracket i2 and dog or knife-edge js away from the plate J.
T is a rod guided in the supporting bracket T and connected at one end with the movable knife-edge js, its other end terminating in a loop or equivalent handle t so that the knife-edge js may be readily pushed into the position shown in dotted lines in Fig. 3 in which it is outot' engagementwith the rack s.
t is acollar securedon the rod T for limiting its outward movement by abutting against the bracket T.
To one o f the arms S is secured the downwardly projecting portion of which (Figs. 2'and 5) serves for the attachment to the carriage M of one end of the ilexible band,
chain or equivalent u the other end of whichv is securedv to the barrel U containing the 'spring by which the carriageis drawn along. This barrel is mounted on a spindle u `secured to the adjustable frame P and at its lower part is provided with the usual ratchet wheel u2 with which engages the pawl 'Lts for preventing the unwinding of the spring contained in the barrel.
At the front part of the fralneP is provided a nut p integral therewith and into which is screwed the back end of the -rod V which is guided so that it may move freely in the direction of its length through a bracket or post 'v secured to or forming part ot' the base- -plate A. The rod V is encircled by the spring n which exerts its pressure between the post fu and a collar o2 rigidly secured Von the front end of the rod V so as to tend always to draw the frame P forward, a vcollar fus adjustable on the rod V serving to limit the extent to which the frame P may be moved i-n a forward direction. v v
To the middle one of the legs or standards b supporting the top plate B is pivoted a bent or bell-crank leverW W the end of the arm W of which is provided with a fingerplate w and the end of the arm W of which is pivoted at w to a bar wzy which vbears against the front of the frame P this bar w being guided in the block w8 so that it may move freely only in the direction ot' its length. To the arm W of lever W W is pivoted the catch arm X which is provided with say two teeth new which are adapted to en gage with the shoulder or face :r4-for holding an arm U thepaper carriage in the proper 'relative positions necessary for the printing ot one or other of the sets of type-faces k k2 7c3 as hereinafter more fully described. The teeth fr, of arm X are pressed into engagement with the shoulder m4. by means of a spring m2 secured on the arm W of lever W W and maybe disengaged from m4 by the operator pressing on the cross-baro;3 secured to the catch armv X.
' Y is a'frame formed on` the end of an arm y rigidly secured to the top plate B and y is a rod 'secured at its lower end to the arm y and at its upper end passing through the segmental frameE and screwed and provided with a nut y2. This arrangement of the arm y y y2 enables the vertical position `*of the frameY to he adjusted and supports it against depression; The opening in the frame Y is such as will accommodate the type heads It and secure them inl position at the moment ot' striking the paper as shown in dotted lines in Fig 2, and the gap y3in one side of the frame Y is provided for the purpose of enabling the last printed matter to be readily seen.
Each type-bar of the before described apparatus is adapted for printing three letters or symbols for each of which the paper earriage is moved into the appropriate position for receiving the particular letter by the op- 1 jv the tooth m engages kthe shoulder x4 as shown in Fig. 2 the type-face k will be that vwhich by each depression of a keyleveris broughtn into contact with the platen M or paper thereon; if the paper carriage occupies its intermediate position, that is when the tooth engages the 'shoulder x4, then the type-face k2 will be that brought into position for printing, and when the paper carriage is -in its foremost position when neither of the teeth 0c engage with :r4 then .the type-face, 7a3 will 4be brought into operation. The three positions, which the lever W W occupies for causing the shifting of the paper carriage for the printing of either of these Asets of typefaces, are indicated in Fig. 2, one in full lines and the other two in dotted lines. A conven- IOO IIO
ient arrangement of the type-faceson the When it is desired to operate the machine the paper is introduced between the roller N2 and platen M. The platen is vthen rotated by means ofthe milled head M2in the direction indicated by the arrowin Fig. 2 so that the paper passes around the platen and between it and the paper guides M5 M6, and'when the edge tirst introduced is in proper position it is-,passe'd beneath the' paper guide N which is drawn back for this purpose in the usual manner. Supposing now that it isdesired to commence with a capital letterz-For this purpose the paper carriage M must occupy its rearrnost position as shown in Fig. 2, the catch arm X and lever W W also occupying the positions shown in full lines in. that figure. The necessary key-lever for imprinting the required capital is then depressed and the type-face 7o" will be brought on to the paper for imprinting that letter, and so on. Should it be required to continue with the printing of capital letters the necessary key-levers are depressed in proper succession while the arm W of lever YV W" still occupies its lowest position. Should it now be desired to print with small letters, it will be necessary to depress the catch arm X by means of the crossbar w3 to disengage a: from :r4 and allow the arm W' of lever W W to be raised by the pressure of the spring v until by the spring rc2 the tooth m of arm X is engaged with as, at which juncture the paper carriage will be in its inter-mediate position having been drawn into that position from its rearmost position by the spring 'U'. In this intermediate position the center of the platen M is directly beneath the point at which the typefaces k2 meet it so that these type-faces only print upon the paper, the type-faces 7.3 and 7c3 standing away free from the paper on either side of the point of contact of the type-face, k2 with the paper. Should it now be desired to print with numbers the catch arm X is again depressed so as to disengage m from r4 and the arm W of lever W W is allowed to assume its highest position the spring e while moving it `to this position also drawing the `paper carriage M into its foremost position, so that the center of the platen is brought immediately beneath the point at which the type-face 7a3 strikes the paper the result being that only the symbol depicted on this typeface will be printed on the paper, the other two type-faces It 7a2 standing clear of the pa per. Ateach operation of a key-lever the appropriate type-head 7.: and shoe K are moved from the'position which they relatively occupy to the type-lever D shown in f ull lines in Fig. 2 to that shown in dotted lines at the part where it strikes the papel', an intermediate point of this reversal of position being shown also in dotted lines in Fig. 2. When the type head 7o is in the position shown in full lines in Fig. 2, the type-faces k .7a2 7.03 receive from the pad c the necessary ink for printing and it will be seen that whereas in this position the type-faces 7c' k2 7c3 are turned away fromthe platen M yet by the link L the shoe K, during the descent ofthe t-ype-lever D, is caused to turn upon the pivot .e so that the type-faces are gradually turned over to the descending side of the type-lever D and are in proper printing position when the type-leverD is at or nearly at the lowest point of the stroke. At each descent of a key-lever or upon the spacing lever G2 being depressed the anchor I is also depressed, this resulting also in the depression of the plate J. At each depres- Sion of the plate J the spring-controlled dog or kfnifeedg@ j? is lowered out ofengagement with the rack teeth s and the fixed dog or knife-,edge j is lowered into engagementwith the rack teeth s. Immediatelyupon the release of the knife edge js from s', the said knife-edge is forced by its spring 7'5 to,` assume the position shown in dotted lines in Fig. 3, so that when the key-leverF or spacinglever Gr2 is next released and raised by its appropriate sp1-ing H and the anchor I and lplate J are raised by their spring j, the knife-edge j which, before its last descent was in engagement with one tooth, will engage with the next tooth, the carriage being drawn forward bythe spring in barrel U to theextent of the width of this tooth until it is stopped by the knife-edge js abutting against the plate J. The width of each tooth corresponds with the amount of movement to be imparted to the carriage for each symbol. Should it be desired to move the carriage toward one or other side of the machine without printing or resorting to the use of the spacing lever G2 this may be speedily effected by pushing the handle t in the direction indicated bythe arrow in Fig. 3 which will have the eiect of pushing the dog or knife-edge js into the position shown in dotted lines in Fig. 3 when it will be quite clear of the rack teeth s and the knife edge j being in its raised position and consequentlyout of engagement with the rack teeth s the carriage may be moved freely in either direction. For line spacing the platen is turned to the required extent by means of the milled head M2 as will be well under-` stood.
The before described apparatus `may be modified without departing from the spirit of the invention. For example as will be obvious, the type-heads 7c instead of having three letters upon them may each be provided with more or less than that number, the frame P and paper carriage M being adjustable to a corresponding number of positions.
