TYPE-WRITING- MACHINE.

Patented July 21, 1914;

Application led November 4, 1919. Serial No. 590,635. l

To all 'whom it may concern;

Be itiknown that I, SIGMUND Sonrrn, a subject of the King of Hungary,'res1d1ng in the borough of Manhattan, city 'of New York, in the county of New Yorkand State of NewYork, have invented certain new and :sol

useful Improvements` in. Type-riting Machines, of which the followingv is a speclcation. Y Y,

The presentinvention relates to an improved means in a typewriting machine for shifting the platen with respect to the paper guide-tol permit of correct and easy intem of key controlled leversvis eliminated,

so that the parts may be few in number, and

of simple construction.` The mechanism is 30l operated directlvby means of a. wheel or similar device on the platen shaft; which,

in certain forms of the invention, maybeone ofthe hand Wheels commonly found at each end ofthe platen shaft. There is Ano. delay or movement of the parts aftr'the.

platen is positioned, to unlock the platen,

before the shifting of the platen is commenced; the' shift-ing commences without any preliminary unlocking movement.

unlocking 'and' shifting movements are re`- solved into a simple rotation of the platen relatively to the eccentric or other device which is used for shifting the same.

I also provide a simple and eective device for preventing shift of the platen ex cept when the same is in such 'position that the shifting mechanism must operate to throw it in the proper-direction. i

In .one form of the invention, a sleeve with' eccentrics attached thereto is mounted 4to turn on the platen axle, the latter journaled inthe platen frame and carrying the usual hand Wheels for rotating it. The ec-v centrics are seated in openings formed in,

a clasp Iand the like at-A In a l form of the invention hereinafter shown the" platen ends eccentrically of the platen to shift the platen transversely of its axis when the eccentrics are rotated relatively to' the 1 platen. .The platen is normally rotated with' vthe platen axle by means of a disk fixed tothe be shifted transversely ofthe axle when the.

eccentrics are `rotated in the platen ends, a hand wheel on said sleeve forming a means eoA for rotating the eccentrics The eccentrics are normally prevented from rotating in the platen and thereby shifting the latter, by means of a pin projecting from the end of `the platen into a circular opening formed in a platev onthe platen frame, and thereby preventing outward movement of thepin except when the latter is brought opposite a slot forming an extension of the circular opening. In another form of the invention, the eccentricsare rotatable on the platen to shift the latter by means of a hand wheel connected toa sleeve loose on the platen axle and movable endwise on the axle into clutching engagement .with the eccentric-V carrying sleeve. 4When the said hand wheel" 'han -wheel is prevented from being moved inward to `connect said clutch by a plate or lcollar on the platen frame, except when the sleeve has been rotated V to bring a pin orprojection lthereon opposite a-notch in said collar, so' that the eccentrics are adjustable `to shift the platen only Awhen the platen and axle have been rotated vtoa predetermined position.v

Other. objects and tionwill hereinafter appear.

In the accompanying' drawing, Figure l is a view inperspective of the platen and 'the means for preventing shift of the platen until the same is turned to proper position. Fig. 4 is a View of the platen and platen shifting mechanism, looking at the right hand end of the platen, the parts being features of the inven ino Ahand end of the platen for shifting` and driving the platen; Fig. 7 is a detail view show- 'l b certain of the parts of the apparatus shown in Fig. 6. l Y

Referring to the forni Of the invention 4shown in Figs. 1-5 included, the platenA shaft 1` is shown as having attached to the ends thereof the h and wheels 2 and 8. Also fast to the platen shaft is the line-spacing wheel 4f which is engaged in the usual manner by a pawl 5 to effect the line spacing movement of the platen 12. The platen is suitably mounted on the platen frame, a portion of which is shown in dotted vlines at 6 in Fig. 2. 4The end lates 7 and 8V of the platen are shown as tted upon eccentric disks 9 and 10 by means of which the platen Yis supported on the platen shaft. The eccentrics 9 and 10 are not, however,

fast to the shaft, but are fast to a sleeve 11` within which the shaft is fitted and which is adapted to be rotated relatively to the shaft for shifting the platen, by means of the eccentrics, transversely of the shaft. For convenience in assembling, the sleeve 11V is shown-in two parts, one part 11il of which carries a wheel 13 by means of which the sleeve is rotated relatively to the shaft. The eccentrics are secured to the sleeve by means of set screws 14, and in order that the two sections of the sleeve may turn together, the right hand eccentric is made fast to both sections by means of two set screws. Fast, by means of a set screw 15, to the left hand end of the shaft, against the end plate 7 of the platen, is a plate or disk 16, which enby means of slots 17 and 18 in the disk with pins 19 and 2O carried by the end plate 7, i such a manner that when the shaft with the disk 16 is rotated the latter acts upon the pin 19 or the pin 20, (according -to the direction of rotation of the shaft), to rotate the platen. The slots 17 and 1S are se1iiicircular in form to permit of the shift of the platen with the pins 19 and 20, when the eccentrics are turned relatively to the platen by means of the hand wheel 13. The plate 16 and the flanges Q1 on the eecentrics prevent longitudinal displacement ofk the platen.

ItA is desirable to prevent shift of the platen except when the eccentrics arein one angular position, indicated in any suitable manner as by means of mark 2201i the face of the platen, said position preferably being such that the platen, when shifted, will be carried away from thev paper guide. The platen with the eccentrics is therefore turned to bring the mark 22 ,to said angular position before hand wheel 13 is `turned to alined.

shift the platen, which position may be indie platen at other times, there is attached to the platen frame 6 a plate having a central circular opening 2lithrough which the platen shaft extends. The pin 20 is not of suihcient length to reach the face of the plate 23, but the pin 19 is extended beyond the face of the disk 16 aiidenters the opening Zet in the plate 23. The opening 24 is of such diameter. that the pin 19 may be turned therein, around the shaft 1 as a pivot, when the disk 16 is revolved with the platen. The periphery ofthe opening 24,

however, closely embraces the path 'of niovei ment of the pin 19v so as to prevent shifting of the platen except when the angular position of the platen is such that the pin 19 registers with a slot 25 in the platev 23, as shown in Fig. 3. When, by means of the mark 22,

'pin 19v has been brought to the Fig. 3,

position, the platen may be shifted by the eccentrics, and the pin 19, movingwith the end plates 7 and 8 of the platen and following its own slot '717, enters the slot 25 in the plate 23.

The norinalfposition of the parts is shown in Fig. 1.` The sleeve 11 which carries' the eccentrics is not locked to the shaft 1 but snugly engages the same. of the platen embrace the eccentrics sufficiently. closely to i prevent play or loose movement between the parts, but not so tightly as to offer appreciable friction to relative rotation of the parts. When the parts are in normal position and the platen shaft is moved by the line spacing wheel or by the hand wheels, the movement of either of these is transmitted to the plate 16. If the movement of the hand wheel 2 is in the direction of the arrow (see Fig. 1),the plate 16, bearing against the pin 19 at the end of the slot 17, carries with it this pin and the platen. If the rotation is in the opposite direction, it is the pin 20 against which the plate 16 bears to rotate thc platen. The ecceiitricity of the eccentrics is not largeandA there is no leverage exerted by the plate 16 which would tend to causo the saine to slip on the eccentric and thereby be shifted. The

.pin 19 furthermore, when bearing against they plate 23, positively prevents the shift of the platen during the normal rotation of the parts. The parts, therefore, ii'rove as a unit either backward or forward under normal conditions.

' "When it is desired to shift the platen, and

the parts are in the position shown in Fig. 3

so that such shifting is possible, the hand wheel 3 is held against rotation, and the wheel 13 with the sleeve 11 is rotated in the direction of the arrow on the wheel 13 in Fig. `1. The movement of the sleeve 11 is For preventing` the shift of the The end plates 7 which pin normally engages the sleeve 32.-

transmitted to the eccentrics, and the plate 16 being held stationary to prevent rotation of the platen, the latter is shifted bodily on the eccentrics from the Fig. 4 position to the Fig. 5 position, so as to move the platen away from the paper guide 26 and feed rolls 27. The pins 19 and 20 are thrown by this movement to the other ends of their slots 17 and 18, and, by engagementwith the endv walls of these slots, serve as-stops-to limit the trhrow .of the-platen. The'paper 28, with clasps 29 or the like, having beeninserted and positioned,the platen is returned to normal position by reverse movement of the Wheel 13, the hand 4wheel 3 being held dur'- ing the returnmovement by the operator.

The return movement to normal position is In the form of the invention shown in Fig.y

6 the wheel -13 is dispensed with, and the hand wheel 2 is mounted so that it may be disconnected from the platen shaft and connected tothe sleeve 11.

3, which 'remains connected to the platen, and turning the handwheel 2,

which has been connected to the sleeve.- In Fig. 6 the plate 16, having its pin and slot engagement with the platen, fis, for convenience of illustration, not shown, but these parts are,

nevertheless, present, and perform the same functions as heretofore ascribed to them. Instead of Athe extension 11a of the sleeve with its wheel 13, the' sleeve in Fig. 6 terminates at the eccentric 10, and the latter carries, in addition to the lflange 21, one member 30 of a clutch for locking the sleeve and eccentrics to vthe hand wheel 2 for 'rotation when the platen is to be shifted. The other member 31 ofthe clutch, which is normally disengaged from the clutch member .30, -is carried by a sleeve 32 to whichhand wheel 2 is xedly attached by means of a set -screw 33. The hand wheel 2 is, however normally connected to the shaft 1, so as to rotate thel latter, bymeans of a pin34 on the shaft,

Sleeve 32 has,.however, abayonet Joint engagement with the pin 34 on the shaft so `that by forcing the hand wheel 2 toward the 69 -theclutch member 31 into'engagement with platen, the sleeve maybe moved-to bring the clutch member- 30. When the sleeve with the hand wheel 2 has thus been moved, the

pin 34 enters that part ofthe bayonet jointj slot 35 which permits'the hand wheel 2 to be this positionof parts The platen may` then be 'shifted by 'holding the hand wheel pressed toward the platen,

trics, relatively to the shaft 1, to which lat-' ter it will be remembered, the hand wheel 3 and plate 16 are fast. This relative' turning movementI therefore causes `the eccentrics to be turned relatively to lthe platen, and the latter to be shifted as described in connecf tion with Figs. 1 to 5 inclusive. After the turning of the sleeve 32 on the. shaft has been commenced, the slot 35 holds the pin 34 so that the 'clutch members cannot disengage, and'pressure on the hand wheel 2 i s no.longer necessary.4 The f relative turning movement of the parts, and the throw of the platen, isdetermined by the pins 19 and 20 engaging the ends of the slots 17 -and 18 (see Fig. 5) The 'pin 34 may however by engagement with the end walls of the s lot 35 serve this purpose. When the platen has been returned to normal position so that the pin 34 may enter .the olfset portion-of the slot 35, a coil compression spring 4'0 throws the clutch member 31, and-with it the sleeve 32 and hand wheel 2, to normal position and the hand wheel 2 is again locked to rotate with -the shaft 1.

A device 23 has hereinbefore been de:

lscribed for preventing shift of the ,platen Aexcept when the eccentrics are in one position, suitably indicated asby a mark 22 on.

the platen. This same device may be used in connection. with shifting mechanism shown in Fig. 6, but in Fig. 6 there. is shown another device for thesame purpose. This vlatter device comprises -a disk or'collar 37, attached to the frame member 36. .and em'- bracing the clutch member 31. On the member 31 is a pin 39, and at one point of the collar 37 isa notch or opening 38. Unless the platen shaft with the platen and with the clutch member 31 is turned to a position to bring the pin 39 opposite the notch or open:

ing 38, the clutch member 31 cannot Abe moved into engagement with the clutch member 30,. because upon any effort to so move the clutch, `the pin '39 will strike the collar plate. 37, and the shift of the clutch member thereby be stopp'cd. When however the platen is firstrotated to correct position with the pin 39 registering wit-h'the opening 38, and the'hand wheel is thereafter the pin 39 passes through opening 38, and theclutch members come ltogether, permitting the shift of the platen.

A' rsum of the operation of the invention as shown in Fig. 6 is as follows: The platen roll and b oth the handwheels and eccentrics i.

being locked to the shaft 1, the same are all turned by either hand wheeluntil the `pin 39 lies opposite the opening 38 in the'framelcarried plate 37. The handle 3 is then held stationary and the handle 2 is pressed against the action of spring 40, until clutch inembers 30 and 31; engage; At this time pinr 'of slots 17 and 1S to stop the shift-ing movement. The paper being inserted, the inovenient is reversed until the pins 19 and 20 engage the lower ends of the slots 1 7. and 18, and the pin 34: in position to permit the spring 40 to throw back the clutch member 31' With the sleeve 32 and handle 2 to normal position, again locking the handle 2 to the shaft l, by means of the bayonet joint, and disenga-ging the handle 2v from the eccentrics.

It Will be noted from the foregoing that no key operated lever system is required to `effect the unlocking and shifting of the platen with respect to the shaft. lt Will also be noted that the moment the relative rotation of the parts commences, the shifting of the platen also commences so that there is no preliminary unlocking movement. lt will be seen that the platen normally rotates Withlthe shaft.

The shaft and the platen, by reason of the eccentrics, are in continuous engagement.

The invention has been shown in tWo forms only, butA it is obvious that all or a number of the features of the invention may be embodied in variousotlier forms Within the scope ofthe invention.
