UNITED STATES WILLIAM 1 QUENTELL,
OF NEW YORK, N. Y.
SPECIFICATION forming part of Letters Patent No. 624,864, dated May 9, 1899.
Application filed May 27,1898. Serial No. 681,943. (No model.)
To all whom it may concern:
Be it known that 1, WILLIAM P. QUENTELL, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Type-Writing Machines, of which'th'e fol-. lowing is a specification.
This invention consists in the novel features of construction set forth in the following specification and claims and illustrated in the annexed drawings, in Which- Figure 1 is a plan view of the machine, partlybroken away. Fig. 2isasectional side elevation on the line 2 2 of Fig. 1. Fig. 3 is a sectional side elevation like Fig. 2, on a larger scale, and some parts broken. Fig. 4 is a plan view of the machine with the carriage and some other parts removed. Fig. 5 is a detail view of a'hammer-detent. Fig. 6 is a rear elevation of certain parts of the machine.
tion. Fig. 8 is a plan view of Fig. 6. Fig. 9 shows the body portion of a type-segment. Fig. 10 is a view like Fig. 9 with the segment-hub added. Fig. 11 is a side elevation of Fig. 8. Fig. 12 is a detail view of aspeeding arrangement serviceable in connection with the spacing-key.
The machine shown in the drawings is of the kind employing a type'segment or wheel. A hammer'suitably actuated strikes or presses the sheet or paper against the required type on the wheel to produce a print or impression. The machine is shown with a base 1, Figs. 1 and 2, and has a way or track 2, Figs. 1 and 3, for apaper-carriage 3. The feeding mechanism of the carriage, comprising a rack 4 and dog 5, is known and need not be described in detail.
The dog 5 has its rock-shaft or fulcrum at 6 and is moved or held to one position by arm 7 and spring 8, secured to a suitable part or fixed post or block 9, Figs. 3 and 4. The dog 5 is rocked against the tension of spring 8 by arm 10, connected or linked at 11 to arm 12, extending from rock-shaft 13, which latter has the laterally-extending arm 14..
- The free end portion of arm "14; as indiengagement with the cross-bar 16 of a hail, the lateral branches of which are shown at 17. The bail has its fulcrum or rook-shaft at 18.
At 20, Fig. 2, are shown the buttons or finger-pieces of the keys or key-levers 21., fulcrumed in asuitable'bearing or strip 22, Fig. 3. The keys extend across or engage the cross piece or bar 16 of bail 16 17, and the keys at opposite sides of the machine also extend, respectively, across the cross pieces or bars 23 of lovers 24, fulcrumed at 26. The levers 24 are shown at opposite sides of the machine. For convenience of description the levers 24 can be called printing-levers. Each such printing-lever, as will presently appear, gives the printing-stroke to hammer 27, Figs.'2, 3, and 4. Say that one-half of the keys 21, or the keys to one side of the machine, act on the cross-piece 23 of one of the levers 24, and the other set of keys actuate the other levers 24. Then as a key of one set or another is actuated the respective printinglever is moved. I
It is noticed that in Fig. l the buttons 20 are shown; but for the sake of clearness the key-levers 21 are omitted in Fig. 4.
The hammer 27 is shown on the pivot 01' with swinging support 28 and has a pin or oppositely-extending lugs 29. Each lever 24 has its rear arm extending positively or di* rectly under or into engagement with pin 29. The depression of a front arm of lever 24 and consequent rise of its rear arm will give an upward .or printing swing or stroke to the hammer.
The fulcru ms 26 are each carried or mount ed on a lever 30, Figs. 3 and 4, conveniently called positioning-levers since, as presently seen, they move the type-segment to bring the required type to printing position.
The positioning-levers are fulcrumed at 31, r
laterally under the keys. When a required key is depressed, it actuates a lever-arm 24, with fulcrum 26, and the consequent swing of the lever 30 swings shoulder-piece 36, with shaft 37, type-segment 42, and arm 43, until the latter is stopped by positive or direct contact with the depressed key. The type-segment has now carried or swung the required type to the printing-point and has come to a stop by the arrest of arm 43.
The lever 30 with fulcrum 26 have come to a stop with the type-segment, but the lever 24, continuing its swing, carries the hammer 27 along until it has made the print. The actuated key being then released, the parts return to rest, as indicated in Figs. 1 and 2.
The paper-carriage can have a sheet stored or rolled in holder 44, Fig. 3, and fed out between rollers 45 46, so as to lie back of plate 47, having a perforation 48, Fig. 6, at the printing-point. The ink-ribbon from spools 49 extends between the sheet and the type-segment, and when the hammer 2'7 forces the paper through opening 48 against the required type an impression is secured.
The hammer 27 is generally so balanced as not to move ahead of time or until the type-segment has been actuated and arrested. In the drawings, however, is shown acam or detent to prevent racing or premature stroke by the hammer. Such cam is shown in detail at 50, Fig. 5, and at Fig. 3 the high part of the cam, or the part farthest from the rod 31, is shown in contact with or in proximity to the hammer 27. The cam is connected to sleeve 51 on fulcrum or rod 31. A bail 52 53 is shown on the shaft 31 and its arms 52 carry a rod 54. The bail is connected to sleeve 51 by the piece 55, connected to such sleeve and to rod 54. A returning-spring 56 engages rod 54.
The lever-arms 25, which engage hammer 27, are step-shaped or formed to engage the cam or its rod 54, so as to actuate the hammer and cam. As a lever-arm 25 raises the cam and hammer, the cam or its high part is held or moved in advance of or clear of the hammer, and said cam being located in the path of the hammer in advance of the latter a premature jump or stroke or excessive speed of the hammer is prevented. The cam is mounted clear of the hammer and is capable of moving out of contact with the latter and is so cut away or shaped that when the cam has been raised a certain distance the low or cut-away portion of the cam permits the hammer to fly forward of its own momentum to print. The hammer is suitably cut away or A slotted, as seen at 87,Figs. 3 and 4, so that as soon as the cam 50 swings up it will clear or free the hammer by coming over the slot 87. Should the hammer acquire excessive speed or jump ahead or away from the lever 25, it will be checked by the cam until the latter has moved sufficiently to clear the way for the hammer. The return-spring 56 can be made to return the hammer and bail, or
these parts might be made of such weight and so arranged or over-balanced as to return without the aid of a spring.
The type-segment is adapted to be made very light and at the same time sufficiently strong or rigid to answer its purpose. As seen in Figs. 9 and 10, the segment consists of an upper and a lower section provided with lugs 57, made to engage one another or soldered or secured together for connecting the sections. The holders 58 are adapted for riveting or securing the type-strip or type in place along the segment-rim 42. The lugs 57 are shown at the outer spokes of thetypesegment. Each segment-section being formed ofa suitable blank, Fig. 7, of sheet or thin metal or stock and being corrugated or bent or flanged along the dotted lines shown in such Fig. 7, such sections will be stiffened and will bring the lugs 57 to engagement with one another. The segment-sections being secured together at suitable distance or space apart, can receive the type-strip therebetween. A sleeve or hub 59, Fig. 10, secured to the hub portions 41 of the two sections, is adapted to fit or be secured to shaft 37.
The holders 58 are shown in Fig. 7 as perforated, and when these holders are bent perpendicular or toward one another, as seen in Fig. 10, screws or rivets passed through such perforations can be made to engage or hold a type strip placed against the holder or lugs 58.
The ribbon-spools 49 are made shiftable or mounted on the shiftable support or plate 60,
Fig. 6, so that such spools can be alternately brought into and out of engagement each with its respective driving-pawl 61 and retaining-pawl 62. One head of each spool being suitably notched, the pawls can engage the spool for driving and preventing retrograde rotation of the latter. The spool-actuating pawls 61 are mounted on rock-shaft 63,
having arm 64, Fig. 11, connected by link 65 with. arm 12, Fig. 6, extending from rockshaft- 13.
The rock-shaft 13, actuated by the keys, as noted, actuates both the pawl-shaft 63 and the dog-shaft 6 or is common to driving mechanism of the spool and carriage. The retaining-pawls 62 are mounted on suitable pivots or bearings and each held bya spring toward its respective spool. A stop 66 can be arranged to prevent each stop-pawl 62 swinging too far or out of place when its spool is shifted clear of the pawl. The rock-shaft 63 swings the driving-pawl 61, so as to give a step-by-step rotation to one or another of the spools to wind the ribbon back and forth. The shaft 63 and pawls 61 and 62, it is noted, are not shiftable.
The plate 60 has a shoulder 67, Fig. 8, and as the plate is shifted it is locked against accidental movement by spring 68 or the shouldered end of said spring engaging one side or another of shoulder 67.
The type-segment when provided with difa the case or shift-levers 69, Fig. 1.
ferent rows of type is made to be shifted by Two suchlevers are shown, the segment being supposed to have three rows of type and the top row being normally in action or printing when the levers 69 are released. A fulcrumblock 71, Fig. 8, supports the screws or fulcrums 72 for the shift-levers fulcru med to sides or lateral faces of the block. On top of the block 71 or between the shift-levers is a fulcrum 73 for a lever, having arms 74 75, the free ends of which are suitably'inclined or cam-shaped, so that when a shift-lever is depressed and a lever-arm 74 or 75 is swung over the depressed shift-key the latter is locked to hold the type for printing wit-h the required case until the lock 74 75 is released. As seen in Fig. 8, the lock-lever can be set so that both arms 7th and 75 are out of action.
As seen in Fig. 11, a block or base-plate 76 is differentially slotted at 77 and 78. Each shift-key 69 has its arms 70 entering into or limited in play by its respective slot. When the shift-key stopped in slot 77 is actuated, the middle case of type will print, while the key in longer slot 78 when swung to its full extent will bring the lowest case of type into action.
'On the plate 76 normally rests plunger 79, adapted to be shifted by the keys .69, and an arm on the plunger is made to engage the seg ment or its hub 59 to shift such segment along shaft 37. This arm, as seenin Fig. 6, is composed of two jointed sections 80 and 81, the section 81 being normally in position orheld by a spring to engage the segmentand being adapted to swingor bend on section 80 to clear or release the segment-as, for example,when the latter is to be taken from the machine.
The writing-keys 21, being fulcrumed a certain distance back in the machine and extending forward, engage the spacing-bail 16 the free end 1.5 of said arm 14.
by resting directly or positively thereon, and each set of keys also engages or rests directly or positively on its respective printing-bail 23. These two bails, being suitably separated or spaced at the center, allow a spacing-key 83, fulcrumed at 18 and normally held raised by spring 19, Fig.- 3, to play or descend without actuating the printing-bails; but such spacer can be made to engage or depress the spacing-bail 16.. To eifeet speeding or enable the key 83 to space with comparatively slight movement, a lever 84, fulcrumed at 85 and made to contact with or support spacer 83 at 86, is placed intermediate the spacingkey. 83 and the arm 14 and is made to engage the latter near the fulcrum or shaft 13-that is to say, at a greater or less distance from The spacer S3 is centrally located or arranged to pass or clear through the central cut or break between the bails 23 without actuating such printing mechanism. The plunger 79, Fig.
11, when freed can be allowed to drop or descend by its weight, or its descent can be secured or aided by a suitably-applied spring.
