SPECIFICATION forming part of Letters Patent No. 755,545, dated March 22, 1904.
Application lefl September 23, 1903. Serial No. 174,389. (No model.)
.To all whom it may con/cern.'
Be it known that we,WILLIAM P. QUENTELL, residing at New York, in the county of New York, and FRANKLIN JUDGE,residing at Brooklyn, in the county of Kings, State of New York, citizens of the United States, have invented new and useful Improvements in Type- Writing Machines, of which the following is a specification.
Io This invention resides in the 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 a machine em- I 5 bodying this invention and the top plate being removed. Fig. 2 is a section along w w, Fig. 1. Fig. 3 is a section along Fig. 1. Fig. 4 is a section along g/ y, Fig. 3, partly broken off. Fig. 5 shows a type wheel or 2o segment and shaft. Fig. 6 shows the top plate inverted with a lock for the type-wheel shaft. Fig. 7 is a section along .e e, Fig. 6. Fig. 8 is a side elevation of part of the typewheel shaft shown in Fig. 5.
2 5 The invention is shown applied to a machine of the kind illustrated in United States Patent No. 713,685, of November 18, 1902, but is not confined to such machine.
The machine is shown with type segment or wheel 1, made to vibrate or give a printing motion or stroke on platen 2, traveling on or across base 3. Key-levers are shown at 10. On a shaft 16 are bearings 17 of levers 19, connected by links 19, Fig. 3, with levers 18,
actuated by the key-levers. Levers 19 strike shoulders 21, so as to oscillate the same with rock shaft or sleeve 22, carrying arm 23, with segment 24, engaging gear 25 of the typewheel. Gear 25, with disk 48 and connectingpin 26, turns or sets the type-wheel.
The type-wheel shaft 27 is shown with a sleeve 29,rotating with gear 25 and carried by frame 30, vibrated, as presently explained, for the printing stroke. With this sleeve rotates a pinion 37, engaging a segment 36, having an arm 39, adapted to be stopped or arrested by the pins 18', each of which is lifted or moved to stopping position by its respective key-lever when depressed.
When a key-lever is depressed, it lifts a pin 5 O and actuates levers 18 and 19, which latter rotate the type-wheel and pinion 37, so as to swing stop-arm 39 until stopped by the pin, which has been raised or brought by its respective key to arresting position. After the rotation of the type-wheel is stopped the continued pull of levers 10 and 18 causes frame 30 to swing so as to dip or strike the type-wheel against the platen.
The segment 36 for convenience of description can be called an index-gear.
Returning springs 38, Fig. 1, for the typewheel and 38 for the type-wheel-carrying frame are suitably applied to revolve the wheel back and lift the same when through a printing stroke or dip.
An escapement is shown to prevent premature dip of the wheel, so that the proper type is first rotated to position to face the printing-point,after which the wheel dips or strikes. This escapement is shown comprising a hook 44, Figs. 3 and 4, which when engaged by bail or look 43 holds the wheel against tilting. This printing-escapement is connected with stop-arm 39, to be released when this arm strikes a stop 18.', the connection being made by a link 71, connected to lever 72, fulcrumed at 78, and extended over the horizontal arms of three-armed lever 73, fulcrumed to the shaft or sleeve of stop-arm 39. Thislever 73 80 is jointed to or actuated by lever 74, fulcrumed at 75 on stop-arm 39 and having projections or T-tail at 7 4', projecting beyond each side of arm 39 when thelever 74 lies parallel along said arm. As the arm 39 comes 85 against an elevated stop the lever-tail being also pressed against such stop will oscillate or press lever 74 to an angle with arm y39, and the consequent swing of levers 73 and 72 will raise the link 71 and lift or move lock or pawl 90 43 out of or clear from hook 44. As the keylever continues to move bail 18 and pull link 19/ the frame 30, with wheel 1, is drawn or pressed to the platen. When the stop or bail 43 engages the arm or depending part 44 of frame 30, the latter is locked against vibration, so that the type-wheel cannot dip.
Case-shift movement can be effected by lever-arm 55, Fig. 3, fulcrumed at 56 and having an arm 58, actuated by one or more shiftkeys. l
A stop 66 limits upward swing of the typewheelwthat is, the backward swing of escapement arm or hook 44. This stop or screw 66 is shown carried by a top plate 79, which is removed in Fig. 1 to expose certain parts.
The stops 18 are shown not as plain or straight rods, but [F shape, so as to have a double guide or be steadied in their movements, the longer shank of each stop resting on the rear portion of its respective key-lever to be moved to raised or stopping position as the key is struck.
The platen feed-rack 47 and dog 46 are familiar, as also the spacing or dog-actuating lever 50, having a cross-bar lifted by each of the keys 10, as also by a spacer-key 10.
The escapement has a certain looseness or play to allow limited freedom or dip to the wheel before the escapement is released. The catch 43, as seen in Fig. 3, does not sit close or tight into the hook 44, so that while the lock 43 is still in the hook the wheel can dip to some extent, but not far enough to strike the platen. When a key is struck, the wheel dips somewhat until the rear high part of hook 44 is arrested against the lock 43, after which the wheel is rotated by a lever 19 until arm 39 is arrested by a stop 18. The continued pressure on key 10 then snaps lock 43 up to clear hook 44, and the wheel on such sudden release is jerked or struck down onto the platen to give a clear print.
Mounted on shaft 16 are cams 80, Fig. i2, engaging pawl-levers 81, fulcrumed at 82 at each side of the machine. These pawl-levers are shown with tooth portions 83,made springy or yielding or in shape of separate springpressed pivoted teeth. Such teeth of separate pieces can be made light, so as to be quick or reliable in action.A
Connected to or moving with index-gear 36 are ratchets 84. As the type-wheel rotates and arm 39 is suddenly stopped the cam 80 has been rocked to swing lever or pawl 81 and press tooth 83 firmly to ratchet 84, whereby rebound of stop-arm 39 `from the struck stop 18 is prevented. Swift operation is thus made possible, but blurring or inaccurate work avoided.
The cam 80 is shown double-acting, or in form of a slotted cam-plate, so as to both move and return the pawl-that is, move the pawl into action or engaging position, as well as to release. Such cams 8O are suitably mounted on or moved by-the rocking frame carrying the type-wheel, so as to move when the type-wheel dips, and the preliminary dip of the type-wheel moves the pawls into action in the machine or frame, such as the top. As
the wheel dips or strikes for a print the extension 85 enters a recess or seat in the lock, so that shift of the shaft or vibration is prevented. The lock is shown with a series of recesses, into one or another of which the extension engages, according to the case being printed. This lock is mentioned as being fixed; but it can be adjusted so as to be in the position required for accurate results. When once adjusted, the lock is to remain as set. Such lock is shown held in place by a screwand-slot connection, the screw being shown at 87. When this fastening-screw is somewhat loosened, the lock can be set backward and when made of hardened steel will resist' wear. rlhe oppositely-extending part of extension 85 moves in a slotted guide-plate 89 and prevents rotation of shaft 27, while allowing its case-shift movements. A spring 90, carried by the rocking frame and made to engage the shaft or extension', will hold or bring the same to normal position-that is, to print the lower or usual case.
A ribbon or spool carrying frame is shown at 91, Fig. 3, having a shaft 92, with ratchet 93 and spools 94. A lever 95 with pawl 96 is provided for the ratchet. A holding-pawl 97 to prevent back rotation is also shown. The spools are loose on the shaft; but by placing either of latches 98, Fig. 1, into engagement with the adjacent spool, while the other spool is left loose, thev latched spool will wind the ribbon 99 freely unwinding from the loose or unlatched spool. The shaft is rotated by the pawl-lever 95, actuated by the dipping typewheel frame or an arm 101, Fig. 1, extended from such frame. The latter as it dips depresses arm or lever 95 to give the pawl 96 and its ratchet a forward or rotation step. The spool-frame is hung or adapted to be swung out of the way to expose the writing. A suitable pivot 100 supports the frame, and an extension of the spool-frame forms a trigger or thumb-piece extending up into easy reach for the frame to be swung.
