WILLIAM W. LASKER, OF NEW YORK, 1N. Y.
TYPE-WRITING MACHINE.
Application filed December 12, 1908.
y To all whom 'it may concern:
Be it known that I, VILL'IAM lV. LAsKnR, a citizen of the United States, and resident of New York city,` borough oi Brooklyn, in the county of Kings and State of New York,
have invented certain new and useful lm# visible writing machines, and the objects of my invention are to lock the type bars from displacement to prevent them :trom becoming jammed together, to permit ready removal and replacement of the type bar supports, tovcause positive feeding of the paper carriage, and generally to simplify the various parts and reduce the number thereof.
My4 invention comprises the novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims. v- Y "Reference is to bc had to the accompanying drawings `forming part hereof, wherein,
Figure 1 is a side elevation of a typewriting machine embodying my invention; Fig. 2 isa perspective view illustrating part of the type loar operating device; Fig. 3 is a detail section substantially on the line 3, 3,

able construction, and at 2 are the key levers having their keys 2n arranged in any suitable or wellknown manner. As a simple and convenient means for detachably and pivotally supporting the key levers 2 I provide frame 1 with a transversely disposed ba r El having one or more longitudinally disposed grooves 3 and transversely disposed slots 3" intersecting the grooves 3, in which slots the end portions of the key levers 2 fit snugly, and the key levers 2 are provided with hubs or projections 2b which fit in the corresponding grooves 3a. whereby said key levers are pi votally supported. The hubs or projections 2 are shown formed on the keyr levers 2 by pressing the same out of the metal of said levers, whereby said hubs are made integral. with the key levers. A plate 4 secured over bar 3 retains the key levers in position in the grooves 3, and by removing said plate any of the key levers may be readily removed and replaced individually without disturbing any of the other key levers. This arrangement provides a simple construction and reduces the number of parts usually employed in typcwriting maciines in pivotally supporting the key levers.l
5 indicates the type bars, which may be made by stamping the same out of suitable sheet metal and attaching the type 6 to the lree ends thereof by a screw or in any suitable manner. The type bars 5 are pivotally supported upon a curved or segment-like support 7 hung' from frame 1, as by screws '8, and frame 1 is provided with a cormally rest. The type bars 5 have individual detachable bearings 9 carried by support 7, for winch .purpose said support is provided with recesses or pockets 7 opening npwardly and in which the bearings 9 snugly fit. The bearings S) are shown as having two side members receiving the type bars 5 between them, which bearings may be made by suitably stamping and bending sheet metal (sce Figs. 2 and 3). Asawsiinple and convenient means oi. pvotallv supporting the type bars inthe bearings J said type bars are provided with hubs or projections 5 pressed out from the material of the bars and entering aperturel il in one member of the bearing i) (see Fig. 3), the opposite side of the type bar being shown resting flush against the corresponding side df bearing 9.
(itl
fio
To apply the type bars to bearings 9 the side members of the latter' may be sprung 4apart to permit the type bars and their hubs to be pushed into place and then the members of the bearings 9 will spring back to pivotally support the type bars, -as in Fig. 3.- The bearings 9 are each set in a seat or pocket 7a of support 7 and said bearings are held firmly in place by screws 10 entering threaded apertures in support 7. The arrangement is such that one screwv 10 may bear against andI holdtwobearings 9 thereby reducing the number of screws required for such purpose (see Fig. 11). By the means described any one of the type bars may be removed and replaced without disturbing any other type bar, and the bearings 9 may be adjusted up and down'as required, for alinement of the type, it being understood that the type bars andtheir bearings are so set that the several type always strike a given pointjwith v respect to the carriage.
The type bars 54 are operated by the key levers as follows: A link 11 is pivotally con.4
nected with each key lever, at 11", and is slidably connected with each type bar. For the latter purpose each type bar is shown provided with a longitudinally substantially horizontally disposed slot 5b, (atjthe side of the pivot opposite type 6) receiving a hub or projection 11a from a corresponding link 11. The hub or projection 11EL is shown pressed out of the metal of link 11 and turned back or bent over the opposite side of type bar 5 (see Fig. 4a), whereby the link is slidably operatively `connected with the type bar, and the link land type bar are retained in proper position. The links 11 each have a rearward projection 11b the under surfacesl of which are shown curved at 11c and` rest upon an abutment,' showny in the form of a transverse bar or roller 12 supported by frame 1, as upon the slotted memf' ber 13 thereof, all whereby as a key lever is depressed it will tend to draw the corre- .sponding link 11, and as the projection 11b of such link rides over the abutment or bar 12 said'link will be cased to swing toward the front, instantly causing a rapid accelerV ating movement, and as its hub 11a slides through the slot 5b of type bar 5 it will cause the latter to swing on its pivot to project its type 6 against the platen of the carriage or the paper thereon. spring 14 attached to each link. 11 and to a rod leta on frame 1 tends normally to draw and maintain the lrespective parts inthe positionsshown in Figs. 1 and 5, for as the key lever is released the spring 14 by drawing back the link 11 will cause the type bar to be depressed and the key lever to be raised. The arrangement is such that the type barsare locked in normal position resting upon ledge or support la as the bearing 9 is disposed between ledge or support l aand the hub er projection 11",
and as the portion of the type bar above slot 5b then bears upon hub 11a the type bar cannot rise or swing because projection 11J of link 11 by bearing upon abutment or rod l2 cannot be depressed by movement imparted direct to type bar 5, but only by the depression of a key lever. By locking the type bars in their normal positions the type bars cannot vibrate, collide or become wedged together and the operation of the machine is thus facilitated.. The pivot 11e is shown similar to 11a, part of link 11 being pressed out and passed through a hole in the key lever and the end of part 11e bent over, see Fig. 4. f
My improved means for feeding the paper 4carriage 'step by step without jumping or vibration are as follows At 15 is a screw or spiral worm extending lengthwise below the paper carriage, and suitably journaled, g5
as by pivots or studs 16 carried by frame 1, which screw or worm is of suitable pitch and preferably is a multiple thread screw. Step by step carriage feeding rotation of said screw 1s given for each depression of 4a'type 90 key or space key, for which purpose I have shown a -suitable ratchet wheel 17 secured atl opposite ends of the screw and operated by pawls 18 carried by rocking arm or lever 19 hung concentric with or upon a suitable 95 Vportion -of screw 15. The rocking armor lever 19 is shown provided with twodepending arms connected together by a cross bar 20 located above the projections 11b of links 11, a brace 21 also being lshown con- 100 worm 15 the appropriate distance rfor each 110 forward step .of the paper carriage. Lugs X11"T are shown normally at a distance back of cross bar 2O so that therey will `.be independent movement of key levers 2 before lugs 11d engage cross bar 20, then before the 115 completion of the down stroke of the keyl/ lever lug 11d' will engage cross bar 2O t6 cause appropriate movement of screw 15. To cause screw 15 tocome to rest just before the key strikes the paper, pawls 18 are 120 disengaged from the corresponding ratchetswhich may be accomplished by means of 'a lug 18a on the pawl engaging stud 22 placed in suitable relation upon 'frame 1 (see Figs. 6 and 7), whereby pawls 18 will 1 25 l be in vengagement with the ratchets for a 4suitable distance of themovement of the pawls and as lugs 18a engage studs 22 and ride on thev latter the pawls will be moved out of engagement with the ratchets and the 130 The relation of the parts screw 15 and the carria e lwill be at rest at vided with a nut or internally the moment the type stri tes the paper. The paper carriage, indicated generally at V25, and which may be of any suitable construction, maybe guided by rod 26 secured upon frame 1 (as bybrackets 27), the carriage being shown provided with yokes open at the bottom fitting over and sliding upon rod 26,- whereby the carriage may be readily lifted olf the frame. The carriafre 25 is prothreaded piece 28ftting the threads of screw or worm 15, and means are rovided for raising and loweringnutf20 cui) of and into engagement with screw 15 as r uired for adjustment of the carriage. Nut L8 is movably connected .with carriage 25, arid for this purpose said nut-'is shown provided with a stem 28 having slots 28b receiving"` the shank portions of screws 29 which are-secured in a lug 30 de- `pending from the carriage, whereby nutf28.
mayhave up and down movement. Nut 28 carries a 1pin 28c that enters a suitable slot 31a in a,
f The inking ribbon, devices are arranged as follows1-Near opposite ends of frame 1 are bearings 35 in which are 'journaled shafts or spindles 36 on which are mounted the vi'nking ribbon rolls or spools 37, any 'suitable' or wellknov'vn guide being provided forre- 4 taining the ribbon 38 in line with the printing position of the platen 25x of the paper carriage. The shafts 36 carry crown ratchets 39 adapted to'be engaged by pawls 40 65 piyntally nonnerted with the levers 19 so' .to cause t be rotated step by step. The pivots of pawls 1'8 and 40 may be made by 'pressing out the metal of said pawls and passing the same through holes in the corresponding lever arm 19., and bending back the metal of such pressed out'hub or pivot in the manner shown in Fig. 4 with respect to hub 11. The pawls 40 at opposite ends of the machine are intended to operate alternately upon the corresponding ratchet 39 to cause the ribbon to wind in one direction or the other on its corresponding spool 37, and for this'puripose .the pawls 40 are located pn'oplposite sides of the corresponding shaft 36,
each pawl 'carrying a pin 41, shown passing through a suitable slot 42 in frame l, which pins are ada ted to be engaged by a movable 'iece of slide 43 carried by frame 1 (see Figs. 1 and 11), saidmovable piece 43 having an inclined or beveled end 43 adapted to engage pin 41 when slide 43 is pushed forward to raise pawl 40 from engagement with the corresponding ratchet 39. Slide 43 is shown provided wlth a slof. 43" receiving a screw 44 carried by frame 1,
' slide 43 also resting on la suitable support 45. Springs 46 connected with frame 1 and with pawls 40 serve to pull the pawls 40 and thus maintain pawls 18 and swinging frame or leversu 19 in normal positions. By pushing one slide 43 under a pin 41 to raise the corresponding pawl 40 out of engagement with the corresponding ratchet 39 the opposite pawl 40 will cause rotation of the corresponding ratchet 39 and ribbon spopl 37 slides 43 the opposite pawl 40 will operate to wind the ribbon in the reverse direction. Springs 50 secured lto frame 1 and bearing against shafts 36 prevent the spools 37 from overrunningz Said springs are shown enlclaims Without departing from the spirit of my inventionf Having now described1 my invention what I claim is 1.
