SPECIFICATION forming part of Letters Patent No. 555,594, dated March 3, 1896.
Application filed March 2 8, 1 8 9 3.
To all whom it may concern.-
Be it known that I, FERDINAND WoLTER, a citizen of the United States, residing at Gaylord, in the county of Sibley and State of Minnesota, have invented certain new and useful Improvements in Type-WVriting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to type-writing and similar machines which produce impressions from individual type or dies brought in succession to a common printing-point, and has for its object to provide certain improvements in the details of the mechanism with the view of producing a more efficient machine.
To these ends the invention consists in certain novel devices and combinations of devices, which Will be hereinafter fully described and will be defined in the claims.
The accompanying drawings illustrate a type writing machine embodying my improvements, wherein, like letters referring to like parts Figure 1 is a plan view of the machine. Fig. 2 is a vertical section from front to rear on the lines X X of Fig. 1. Fig. 3 is adetail in plan showing the carriage-bed or guide- Way and a part of the carriage-frame, ribbon, &c. Fig. 4 and 5 are details, respectively, in section and outside elevation, showing the bearing-flange, type-levers, &c-. Fig. 6 is a detail in outside elevation, showing one of the connecting-rods for operating the type-levers from the keys. Fig. 7 is a detail in section, showing the aligning-funnel. Fig. 8 is a detail in horizontal section and plan view, illustrating the feed mechanism for rotating the inking-brush and imparting a longitudinal movement to the ribbon. Fig. 9 is a detail in left end elevation, showing part of the carriage, swinging'paper-roll or platen, &c. Fig. 10 is a vertical section on the line X X of Fig. 1. showing the line-feed mechanism.
Fig. 11 is a bottom view of part of the carriage, showing guide-bands for the paper, to. Fig. 12 is a detail in cross-section on the line X X of Fig. 11, some parts being removed. Fig. 13 is a central cross-section through the paper-roll andfeed-roll on the line X X of Serial No. 46 7,944. (No model.)
Fig. 11, some parts being broken away. Fig. 14 is a plan view showing the guide-slips for the type-carriersand the means for supporting the same. Fig. 15 is a detail partly in section and partly in elevation, showing the cam-lever used for releasing the feed-dogs from the feed-ratchet automatically on the return of the carriage. Fig. 16 is a detail in sectional elevation of the connecting-rod to the adjustable stop for varying the throw of the flexible or pivoted member of the feeddog. Fig. 17 is a detail in side elevation of one of the guide-slips for the type-carriers. Fig. 18 is a detail partly in plan and partly in horizontal section, showing part of the manual feed-dog-releasing device.
A bed-plate or casting a, vertical pillars a, an annular head-plate a and cross-bars a a constitute together the main frame of the machine, which in its main design or outline is similar to that of well-known standard machines.
w are vertical extensions from the main frame, and a a horizontal shelf supported thereby and constituting the bed or guideway, upon which rests and travels the papercarriage and to which are fixed various parts of the mechanism.
b are the keylevers, which are provided with notches b at their rear ends, held up by springs b in engagement with a knife-edged fulcrum-bar b at the rear end of the bedplate. This fulcrum-bar b is spaced apart a short distance from the body of the bed-plate. This arrangement of the fulcrum bar 19 notches b and the upholding-springs 6 permits the key-levers to be independently detached and removed from the fulcrum-bar at will by simply depressing the rear ends of the levers against the springs b and at the lie a cross-bar c on a vertically-movable feedplunger 0 subject to the action of the keys and the said feed-bail in one direction and to a strong retractingspring 0 in the other. The feed-plunger c works through a lower end guide, 0, fixed to the rear cross-bar, a of the frame and through an elongated slot 0 in the rear flange of the annular head-plate a the said slot permitting to the upper end of the feed-plunger a limited swinging movement from front to rear, the same being normally held to the front limit of the said slot by a strong spring a on the top of the headplate a the tension of which is adjustable by an eccentric lever a. At its upper end the feed-plunger c" carries a pair of escapementdogs 0 and c, of which the former is the fixed and the latter the flexible or pivoted member and subject to the action of a light spring 0 The feed-dogs c and c engage with the feed-ratchet c on one of the rear cross-bars of the carriage for imparting the letter-feed movements thereto under the action of the feed-plunger 0 The pivoted or flexible dog 0 works through a keeper 0, carried by the rigid dog 0 and the throw of the same, under the action of its spring 0 is limited by an adjustable stop 0 held and guided on the top of the head-plate a by a slot-andpin engagement therewith as shown at 0 The stem of this stop e is connected to a bell-crank c", pivoted at its angle to the headplate a and provided with a pull-rod extended forward to within reach of the operator of the keyboard and provided with notches c en gageable with a fixed keeper 0 at the front right-hand corner of the cap-plate to hold the said feed-stop e in any desired adjustment. The stop 0 may therefore be set to permit the feed-dogs to take one or more of the teeth of the feed-ratchet e at every escapement movement, according to the spacing desired. The further connections from the feed mechanism and the action of the same will be described later on.
d are the type-bars, and d d the carriers for the same, of which parts (Z is the body portion composed of a straight rod, and d is an enlarged head on the same, which carries the type on its tip or. extreme upper end, and is set at an angle to the rod (Z or body portion of the carrier. The head portions (1 of the carriers are larger in cross-section than the type-bars (Z and made tapering, thereby servin g to protect the type and taking all the wear and tear from the aligning action on the carrier-heads and making it impossible for the type-face becoming battered by an accidental collision of the carriers, as the taper would cause them to glance oif. This arrangement also prevents any looking or hooking of the type-bars, as is the case with other lever arrangement.
The type-carriers (Z d are suspended and operated by radially-swinging levers d ,pi\*otally attached to the carriers at a point intermediate of their extremities and near the center of the same. The levers d are provided at their upper ends with lateral bearing-lugs (1 (see Figs. 2, 4c and 5,) which engage with hook-like lug-seats d turned up from a notched annular bearing-flange cl, which is secured to the lower inner margin of the ann ular cap-plate a An annular locking-band cl works on the rear vertical face of the bear ing-flange cl above the lug-seats (l and has a slot-and-pin engagement with said bearingflange, as shown at d in Fig. 5, the slot of which is cut at an angle to the plane of the rings movement. This construction will cause the locking-band to rise or lower on the flange (1 when turned thereon. Hence the said band serves as a convenient common lock for securing all of the levers d" from displacement when in their working positions on the lug-seats (1 while, at the same time, it may be readily raised, so as to permit the levers to be removed from the bearing-flange d.
The type-levers d are adjustably united by eye-screws d with the upper end or forked section of the key-lever-connecting rods b 0 h of which parts Z) is a rigid rod made fast to the key-levers, b is a buckle, and b is a two-pronged or forked upper end section, one member of which carries a pivot-stud b for engagement with the eye-screws d and the other member of which is engageable with the free end of the pivot and disengageable therefrom by a yielding or spring action, as shown in Figs. 4 and 6. This special feature of construction permits the key-connecting rods to be readily disengaged from the carrier-swinging levers d". The eye-screws d afford a convenient means for adjusting the throw or radial movement of the type-swingin g levers (1 The type-carriers cl (1 are in circular arrangement within the annular head-plate a and normally rest with their heads (1 against an annular buffer d composed of leather or other similar stiff yielding material secured to the inner upper corner of the annular head-- plate a By a radial and endwise movement the typecarriers (1 d are thrown to a common point of impression in the axial line of the circle through a bell-mouthed aligning block or f unnelf, placed mouth downward and secured rigidly to the bed a, over which the papercarriage moves. The aligning-funnel f is preferably provided with a removable bushing f, to take the wear and tear from the carrier-heads (1, which bushing, as shown, is removably secured to the upper end of the funnel bya set-screw f The curve of the mouth of the funnel corresponds to the curve of the type-carriers in passing to the printing-point.
The type-carriers d (1 work between radially-arranged horizontal guide-slips g, which are composed of comparatively-light but stiif or unyielding material and are loosely seated in an annular groove g on the inner face of the annular l1ead-plate a at their outer end, and are provided at their inner ends with notches 9 which overhang the vertical flange 1 of a cup-shaped bearing-head 9 carried on the upper end of a vertical standard g g rising from the bed-plate in the axial line of the aligning-funnel f or type-carrier circle. At their outer ends the guide-slips g are flattened, so as to substantially fill the groove or seat g in which they are held and properly space the same apart togive clearance for the type-carriers. The guide-slips converge toward the bearing-cup g on the vertical flange of which their inner ends rest in close contact with each other, but loosely seated, so as to be free to for example,,the inner ends of the guide-slips 9 may be made to so fully fill up the flange,
of the bearing-cup g as'to give only lateral spread enough for the entrance of one carrier, in which event two carriers could never come near enough to strike or interfere with each other. The guide-slips should be sufficiently stiff so as not to bend or yield laterally under the action of the carriers.
g is a removable lock flange or collar fitting over the top of the standard g, with its flange overhanging the inner ends of the guide-slips and preventing their removal from the bearing-cup g without the removal of the said lock-collar and itsjam-nut The lower or tail ends of the carriers 61 61' work through guide-passages g of an annular guide or disk 9 fixed to the standard g g and serving to hold the type-carriers at that point at a fixed distance from the standard or axial line of the circle, while permitting a free endwise movement to the carriers, under the action of the keys and the type-swinging levers (1 This annular guide 9 is preferaby composed of leather or other similar stifi yielding material, as this gives the best bearing for the carriers in the action to which they are constrained by this tail-end guide.
As a convenient construction for securing the leather disk 9 in position, the standard g g is composed of two sections, having expanded disk-like clamping-surfaces g between which the leather disk d is held, and the lower member of which is provided with a screw-threaded extension 9, engaging a screw-threaded socket g on the upper section g and working through a perforation in the leather disk.
WV ith the parts so far described it is obvious that under the action of the keys the typecarriers will be directly thrown by a continuous radial and endwise movement to the common point of impression through the aligning-funnel f, and that letter-feed movements will be imparted to the feed-plunger c and the escapement feed -dogs carried thereby and working with a vertical action on the horizontal feed-rack 0 It will be noted that the type-heads d of the type-carriers d d are formed with a taper, diverging upward from the stem portions 61 and blending into the enlarged type heads d. This is a desirable construction, inasmuch as it prevents the interlocking of the carriers in case of engagement and protects the type from being mutilated or defaced.
Turning now to the paper-carriage and its connected parts, h represents the longitudinal bottom bars or runners, and h the end cross bars or plates constituting together the main frame of the carriage. The runnerbars it ride on horizontal rollers 7L2 j ournaled in the carriage guide-bed a, and are prevented from lateral displacement by vertical guide-flanges a rising from the guide-bed and engaging with the outer vertical surfaces of the runner-bars h. The carriage-frame is provided with a longitudinal banking-bar h which, as shown, is at the rear of the frame and carries on its under surface the letterfeed ratchet 0 straight edge which engages with a banking This banking-bar h has a projection, which, as shown, is in the form of a roller 71 in line with the impression-point crosswise of the carriage guide bed. or ways. The banking-roller 71 regarded relative to crosswise movement of the carriage on its guide-bed, is fixed, and hence under the forward tension on the said carriage from the spring 0 applied to hold the top of the feedplunger 0 in its extreme forward position the said aligning-bar 7L will be made to hug the banking-roller h at a point inline with the point of impression, thereby insuring the accurate centering ofthe paper-roll or platen with the aligning-aperture of the aligningfunnel f, preserving alignment of work regardless of play in the carriage. For convenience, with respect to the removal of the carriage, the said banking-roller 77. is not journaled in a fixed bearing, but is carried by a pivoted orlever-like bearing h, (see Fig. 3,) which is held normally against a fixed stop-pin h by a strong spring h of so much greater strength than the spring 0 applied to force the top of the feed-plunger 0 forward and the carriage crosswise of its bed in a forward direction, as to render the said roller rigid against the strain from the spring 0 as hitherto stated, while at the same time the said roller may be sprung forward to permit the removal of the carriage from its bed. The front carriage-runner is held down to the bed by a spring-clip 71. which maybe turned forward against the tension of its spring h so as to disengage the carriage at the front of the frame when it is desired to remove the same.
The carriage is under tension to move toward the left from a driving-spring It, made fast to the head-plate a at one end and applied at its other end, through a cord or wire 70, toa strap-drum spool 70 set in a Vertical riage-frame.
position and provided with an eccentric strapdrum 70 connected by a strap k to a hook 15 as shown, fixed to the right end of the carriage-frame. The upper end bearing for the spool-shaft k is given by a yoke shaped bracket 713 rising from the head plate a Under the strain from the spring 70 the carriage will be fed toward the left, as permitted by the escapement-dogs and o under the action of the feed-plunger c and the key-le vers to effect the letter-feed.
It should be noted in respect to the action of the feed-clog which is the rigid or looking member in engagement with the feedratchet 0 when the feed-plunger is in its lowermost position and the type-carrier at the point of impression, that it is inclined or provided with a cam-surface 0 on its forward or engaging edge, which by its camming action assists the spring 0 in aligning and looking the paper-roll or platen at the point of impression when the impression of the type is being made under the action of the key.
In virtue of the banking-roller 7L bankingbar h and the co-operative parts just hereinbefore described, the carriage may be permitted to work loosely on its guide-bed a between the retaining guide-fianges a and yet be perfectly centered or aligned at the printing-point. This gives a free and easy feed to the carriage and does not require any nice fittings of the carriage-runners and guideways, and permits the use of platen and carriage nearly the full width of the machine.
The paper-roll or platen p is journaled in hangers p, which, as shown, are of segmental form, pivoted to the end plates h of the car- This permits the paper-roll or platen to be swung forward and upward for inspection of the work. A bell-crank rocker or hand-lever p is pivoted to the left-hand forward corner of the carriage and connected by a link 19 with the left end hanger, 19, and is subject to the action of a spring 12 tending to hold the said lever and the paper-roll or platen p in its normal position with the link 12 abutting at its rear end against the fixed stop 19 rising from the carriage-frame. The handle of the rocker or bell-crank 19 projects toward the front within easy reach of the operator, for operation by the left hand to throw up the paper-roll and expose the work. This swinging paper-roll would be a convenience on any machine, but is especially desirable on this machine, inasmuch as the carriage-frame does not have a pivotal motion.
At its right end the paper-roll is provided with an annular ratchet p, engaged by a spring-retaining pawl 197 and a driving-pawl p pivoted to the upper end of a pivoted lever 1), extending outward and pivoted to a corresponding projection 19 from the right-hand plate of the carriage-frame, as shown at p. The lever 13 carries a flat spring 19 overarching the pivot 13 and bearing at its upper and free end on the driving-pawl p and serving both to hold the driving-pawl p in engagement with the annular ratchet p and to throw the lever 19, with the pawl 12, downward at its upper end to give the feed-stroke for the pawl 19 The upward throw of the pawl 19 maybe limited by a turn-button stop 12, having two or more stop surfaces or steps for single or double spacing, as may be required. The line-spacing lever 19, with its co-operating rigid arm 19 projects forward from the right end of the carriage to within reach of the operators right hand, so that the carriage may be returned to the right end of its runway and the line-feed be effected at the same time by grasping the levers p and p" with one hand.
The feed-roll p is j ournaled in hangers p pivoted back of the paper-roll to the paperroll hangers p, as shown at 17 The feedroll hangers p are connected by a common bar 19", which is subject to the crank end of a rock-shaft p journaled in the rear crossbar, 13 connecting the paper-roll hangers p, and provided on its upper end with a handlever p The crank-ended rock-shaft 19" serves as an adjustable stop for varying the tension on the feed-roll 19 through the bar 1)", thus giving a yielding pressure on the paper and when thrown back admits of an easy removal of the paper.
19 is the paper-shelf or feed-board carried by the hangers 19 p are spring guide-bands for the paper, secured to and adjustable on a longitudinal guide-rod 11 located directly below the feedroll and having its ends made fast to the hangers p. The spring-bands 19 have rearward projections which underlie the feed-roll, and their free ends extend forward and upward and are bent into aloop to increase their flexibility or yielding action, and the outturned tips of the same rest and ride upon the front cross-bar, 1), connecting the paperroll hangers 1). These spring guide-bandsp it will thus be seen, co-operate with the pa per-shelf and feed-roll to form continuous yielding guides for holding the paper to the paper-roll or platen throughout its entire travel, from the point of entrance to the point of delivery, and admits of the use any size of paper.
An envelope-clip p is pivoted to a central projection p on the front cross-bar, p and held under spring-tension by a spring-finger p for use either alone or in co-operation with either or both of the intermediate paper-guide bands 19 to hold envelopes or narrow paper. The finger may be thrown back while paper is inserted.
The ribbon r is mounted on spools r at the opposite ends and below the carriage guidebed a, and passing up through slots r therein and moving longitudinally over the top of the aligning-funnel f and under the platen at the point of impression. For imparting the 1011- gitudinal feed to the ribbon 0 one of the spools r, the left member as shown, is provided with an extended shaft 0*, j ournaled at its forward end in the bracket-arm r and provided with a ratchet-wheel r engaged by a retainingpawl r and by a feed-pawl 0*". The feed-pawl r is carried on the forward end of a pivot-ed cam-lever r pivoted, as shown at r", to the left end of the head-plate a under the carriage-guideway a? (see Figs. 1 and 8) and subject to the action of a cam r carried on the drum-shaft 70 under the strap-drum k and also subject to the action of a spring 0*, workthrough a keeper 7", which rests on the guidebed a and is provided with a slot 7- directly over the aperture of the aligning-funnel f. This keeper r is normally held by a spring 4 thrown forward, so that a projection r thereon rides against the inner vertical face of a horizontal cam-plate r fixed to the front member of the carriage-runners h and provided with zigzag inclined surface 1", which under the movement of the carriage in co-operation with the spring T will throw I the keeper 7' and the ribbon r successively toward the rear and toward the front across the point of impression, thus giving to the ribbon a lateral feed, as stated. The keeper 7 is provided with a shifting rod T, by which the same may be thrown back into an idle or inoperative position, together with the ribbon held thereby, and be secured in this idle position by a pivoted button 1", engaging with the front end of the shifting-rod W. This is a convenience when it is desired for any reason to expose the tip of the aligning-funnel or. a type-carrier held up therein and when it is desired to employ direct-printin g devices without the use of the ribbon. For this purpose of direct printing I provide an annular inking-brush t, supplied by an automatic inkfeed and located in the path of the type-carriers as they are moved toward and from the point of impression.
In my preferred arrangement I carry the brush t on the under surface of an annular disk t", which turns on the lower projecting end of the funnel f, as a pivot, and is removably upheld by pivoted crank-arm hangers t projecting downward from the carriage,
guide-bed a, the crank ends of which may be made tounderlie the said disk and hold the same up in working position. The top surface of the disk t is provided with annular recesses 15 having feed-ducts 15 leading to the .top of the brush t, which annular grooves or recesses are filled with some suitable absorbent material t for holding the ink and giving the proper feed. An annular shield or cover if is placed over the top of the disk 15 to hold the absorbent material in position and exclude the dust.
The disk 1 is provided with an annular ratchet t, which is engaged by a spring-held pawl 25 carried by the ribbon-feeding camlever r By these connections 25 and 25 to the said ca1n-lever 7' operated as heretofore described under the movement of the carriage, the inking-brush twill be kept constantly rotating with a very slow movement, thus insuring an even usage of all parts of the brush on the type, under the movement of the carriers. It is possible to use these direct-inking devices, together with the ribbon, and when so used it will keep the ribbon supplied with ink. The ribbon may, if so desired, be set out of working position. I also provide a type-cleaning brush w, which is of annular form and is secured to the under surface of the hood-flange a which is secured to the head-plate a and overarches the buffer-ring d This locates the cleaning-brush w in the path of the type in their movement to and from the impression-point, and will keep the same clean of all dust and other easily-removed matter.
l/Vith a view of giving better control of the carriage I provide a manual feed-dog-releasing device, consisting of a pivoted lever .2, carried by a post 2 depending from the rear flange of the head-plate a one end of which is slotted, as shown at 2 and engages with the feed-plunger c and the other end of which lever is connected by a rod 2 with a bell-crank z, pivoted to the left-hand front pillar, a, of the frame directly above the keyboard and provided with a laterally extended or expanded hand-rest .2 The bell-crank z is also connected by a link 2 to a spring-lever 5 projecting from the head-plate and provided with the fin ger-rest or handle 2 Under the action of the spring-lever .2 the bellcrank will be held up at its forward end and the lever .2 will either have no action on the feed-plunger of or will tend to assist in holding the same, together with the feed-dogs carried thereby, in their forward or engaging position; but by pressing down, either on the hand-rest .2 or the fin ger-rest .2 the left end of the lever .2 will be drawn toward the front and the right end of the same will be thrown toward the rear, thereby forcing backward the top of the feed-plunger c and throwing the escapement feed-dogs 0 0 out of engagement with the feed-ratchet 0 This enables the operator to move the carriage backward or forward at will independently of the feeddogs.
I also provide an automatic releasing device for rendering the feed-dogs inoperative on the feed-ratchet 0 during the return movement of the carriage. For this purpose I provide a cam-bar Z9 onthe carriage-frame directly above the banking-bar k with which engages a cam-leverz having a longitudinal slot 2 through which by set-screw 2 it is pivoted to a bracket-arm e projecting from the rear flange, d of the carriage guide-bed (1. The rear end of the cam-lever z is in position to operate directly or indirectly on the feed-dogs to throw the same toward the rear. As shown, the rigid dog 0 is provided with a lateral projection .2, against which the rear end of the cam-lever bears. The cam lever 2 carries a spring-finger e which engagesa releasing-ratchet 2 fixed to the ca1nbar 2-. On the forward or letter-feed movement of the carriage the said pawl will slip over the ratchet 5 but the instant that the carriage is reversed the pawl will be caught by the ratchet and the lever 2 will be rocked and at the same time thrown toward the rear, thereby forcing the feed-dogs out of engagement with the feed-ratchet 0 The cam-bar z and the ratchet .2 are cut away near the left end of the carriage-frame, so as to leave a clearance-space a", into which the pawl .2 and the front end of the lever .2 may fall when the carriage is at the extreme right of its runway, thereby permitting the feed-dogs to assume their active position in engagement with the feed-ratchet The general operation of the machine is similar to that of the ordinary standard typewriters, the nature of which action is so well known and is so obvious from the preceding description that a repetition or summary statement of the same is not deemed neces sary for the purposes of this case. The actions and advantages of myimproveinents in thedetails of the mechanism have been stated in connection with the specification and detailed description of the respective parts. It may be noted in a general Way, however, that the machine is comparatively easy to make, is light of touch, quick in action, accurate in alignment, and distinct in impression.
