Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed May 9,1904- Serial No. 207,175.

To all whom, 1125 "may runner-rt:

Be it known that I, MARSHALL J. PAYNE, a resident of Staunton, Virginia, have invented a new and useful Improvement in Type- Writers, which invention is fully set forth in the following specification.

This invention relatesto type-writers, and more particularly to platen-rotating or linespacing mechanism therefor.

The object of the invention is to provide means whereby the platen may be rotated by devices operatively connected to key-levers extending to the keyboard.

The device is so constructed that the platen ma be rotated by keys from the keyboard without regard to the position of the carriage.

The device is further applied to typcwriters of any standard make having a reciprocating carriage and to type-writers having a reciprocating carriage and devices for the return of the carriage, and more particularly applied to the device as set forth in Patent No. 782,112, granted on application Serial No. 165,169, iiled July 11, 1903. W'hen as sociated with a carriage-return device controlled from the keyboard, I have provided means .to rotate the platen and free the mechanism restraining the carriage-return device. ()ne of the levers employed to actuate the platen-rotating device is operativcly connected to the lever tripping the pawls rel straining the carriage-return spring. It is desired, however, that the platen be rotated the required dlstance ust before the pawls restraining the carriage return device are withdrawn. It 13 further desired that the lever acting to withdraw the pawls be locked in a position holding the pawls out of engagementwith the ratchet on the spring barrel of the carriage-return spring until the carriage is fully returned from left to right and then the lever so acting be automatically released. It is desired, howeverfto restore the lever actuating the platen-rotating mechanism to a normal position just as the finger is lifted or the rotation of the platen is completed. I have therefore devised novel means of accomplishing the rotating of the platen and freeing of the carriage-return device and in addition means of rotating the platen independent of the carriage-return. I have also devised novel means of adjusting the device .for one or a. plurality of spaces, in combina- 1 tion with a device employed to withdraw the pawl from operative engagement with the ratchet on the platen except when the same The invention may receive various mechanical expressions, the preferable construction, however, being illustrated in the accompanying drawings, in which Figure 1 is a partial perspective looking from the right hand rear corner. Fig. 2 shows a modification of certain parts illustrated in Fig. 1 and shows more particularly the preferable plan of constructing the parts therein illustrated. Fig. 3 illustrates the lmec-hanism I employ for withdrawing the pawl from engagement with the ratchet on the platen-shaft and the means of adjusting the device for a greater oi" lesser throw of the platen. Fig. 4 shows a modification of certain parts illustrated in Fig, 1, and this construction of the parts allows me to-dispense with the lever 11: Fig. 5 is a rear elevation of the type-writing machine used in connection with the present invention. A carriage-adliancing device constructed in any well-known manner and a carriagereturn device supplied with any motorpowcr and a device restraining the carriage: return device are here shown and will be more specifically described and referred to hereinafter in the specification and claims.

Referring to the drawings, Fig. 1 illustratcs the lever 1 supporting key 2, fulcrumed at 3 on the rod 3, which rod acts as a bearing for the typical type-levers 44 and issuitably fastened to the frame of the machine. Lever 1 1 supporting key 11 is similarly fulcrumcd to rod 3 at 12. Spring 4 and s ring 13 act to restore the levers 1 and 11 w icn depressed to a normal position. l Journaled on the frame of the machine at 8 and 9 is the shaft 7, which shaft is laced beneath the keybearing levers, ((lhsignated typically as 44.) Mounted securely on shaft 7 is the crank member 6, and rigidly secured to the said crank member is the laterally-projecting pin 5,resting 'normally just under the lower edge or surface f lever 1. This pin is preferably provided with an antifrictionroller. bearing. are an exact counter art to the crank member before describe the pin 15 normally is in the immediate act of rotating the platen.'

Crank member 10 and pin 15' of a type -writer and illustrates certain parts Egg resting just beneath the lower edge of lever 11. I 7

Spring 14, fastened to the shaft 7 and to any suitable part of the machine, acts to return the shaft to a normal position Whenever the sameis rotated. The arm is securely mounted on shaft 7 and connected to the pull-rod 18 by any suitable connection. The pull-rod 18 is likewise connected. to arm 19, the said arm 19 being securely fitted to the rock-shaft 19. The shaft 19 is suitably journaled on the 11 per rearpcrtion oi the machine prif 'erab y near the center or the travel of the well-known carriage. Member 19 fastened to shaft 19 and supporting the ballbearing 20, should be just at the center of the travel of the carriage, ball 20 being in .op-

erative relation to thevibrating bar or blade The said bar or blade 22 1S pivoted on- 30 sets to return the-lever 29 to a normal po sition whenever the actuating force is withdrawn. Spring 31 acts to normally force pawl B i'into operative engagement with the ratchet-wheel 37",. The function of the ball and the ball-bearing at 20 is to relievethe iction ofthe parts and to allow for motion in two directions.

Lever 40, having bearing at 42 and supporting key 41 and provided with a rearwardly-extending arm resting under awls 8 and18 at 43 and being also provide( with a lock 23, is'fully described in Patent-No. 782,111, ranted on application Serial No.

155,169, iled July 11, 1903.- The functionof the lever40 is as follows: When key 41 is depressed, it causes a corresponding elevation of the rearwardly-extending arm of lever 40, which acts to lift the pawls 8 and 18 resting on lever 40 and to withdraw the said pawls from engagement with the ratchetwheel on the spring-barrel of the carriage-re turn spring. I

In order that the pawls 8 and 18 be disengaged during the return of the carriage, it is required to retain the rearward end or arm of the lever 40 in an elevated position during the return movement of the carriage. Am suitable device may be employed therefor, however.

In Fig. 1 a lock illustrated that may be clearly understood by refcrcncc 1n the drawings. The latch 23 is su mounted othe frame 52.

senses nose engages the lever 40 whenever the rear ward arm is elevated, and thereby retains said arm in that position,

The release mechanismis simply a bellcrank lever 23 fulcrumed on the machineframe and having one arm connected to the latch 23 and the other arm connected to a pull-rod 23". A ull on the said rod acts to withdraw the late from engagement with the lever. 10', and said lever isthenrestored to a normal position by spring 40 The member 39, rigidly secured to lever 1 and extending in an upward direction, terminates in a lateral extending projection 39,

overhanginglever 40. The'function of the said member is as follows: When lever 1 is depressed, the said member 39 traveling therewith after a predetermined distance comes into contact with or en ages the uppcr edge or border of lever 40, which then acts to pull lever in a downward direction. The'lever 40 and the-lever 1 havin reached the end of their respective travel, ever 40 is locked in a depressed position; but the lever: 1, carrying member 39, is restored by virtue of spring 4 to a normal position in advance of lever 40.

In this WayI avoid friction between the bar 22 and the ball-bearing 20. Furthermore,

the parts are allowed to return to a normal position and all stress or friction of bearing is reducedto a minimum.

' Referring to thedrawings, Fig. 5, on any suitable framework 44 is mounted the cari riage-advancing mechanism 45, connected tothe carriage 47 and bearing the platen 48 by the cable 46; The carriage-advancing mechanism is constructed in any well-known manner and permits the carriage to be advanced step by step as the characters are printed.

On the opposite side of the machine from the carria.gc-a 'lvancing mechanism is the carriage-return device, in which the shaft 55 is suitably journaled in the frame 52 and having keyed thereon the ratchet-wheel 56 and the gear-wheel 54, the gear-wheel 53 having bearing on the shaft 51 the gear-wheel 54 and connected to the ul ley 50, likewise having bearing on the s aft 51*. i The shaft 51 is suitably journaled in fastened to the periphery of the pulley 50 and the other one right Whenever the carriage-return mechan 15m is actuated. pivoted on the frame 52 in such position as and meshing with The cable 49, having one end.

secured to the carriage 47, acts to withdrawthe carriage from left to lot IIO

The retaining-pawl 18 is to engage the ratchet-teeth on tho ratchetwheel 56 and to restrain it until tllc lever 40,

resting just under the tail of the said pawl. is operated' Whenever the lever 14) is operated, it acts to withdraw the pawl l from engagement with the ratchet-wheel it) and to tree the mechanism Ejusl now described. I that its 4 wish It distinctly uni erstood, in: a over. that the principle of my invention does not restrict me to any motive power that may be employed to actuate the carriage-advancing device or the carriage-return device.

The action of the mechanism as so far described is as follows: Should it be desired at the end of the written line to return the carriage to the extreme right-hand position and to rotate the platenthe required distance for the next line, all that is required is to press the key 2, which acts to correspondingly dcpress lever i, and consequently rotate the eccentric member 6 and with it shaft 7 arm 16 therefore acting to rotate shaft 19 through the pull-rod 18'. The rotation of shaft 19 acts to cause ball bearing 20 to en age and vibrate the vibrating member 22, which acts to elevate the arm 27, causing a correspond ing elevation of the 'rcarwardly-extending arm of lever The forward end of lever 29 as will be plainly seen, is therefore depressed, and with it pawl 34, the same acting to rotate the platen by cn aging the toothed wheel 37", supported on t e platen-shaft 37. So soon as the actuating force is relieved the spring 14 acts to return the shafts 7 and 19 to a normal position, and the efore allows all the parts to assume a normal position, as before described. The downward travel of lever 1, carrying with it member 39 supported thereon, engages lever 40, as before ex lained, after a predetermined distance and t \e same acting to withdniw pawls 8 and 18 and allow the carriage to be returned in virtue of the function ,of the carriage-return spring.

Should it be desired to rotate the platen without returning the carriage, as is frequently the case, all that is necessary is to press key li which acts to rotate crank member and cause the rotation of shaft 7, the mechanism thereafter being the same as before described.

' Fig. 2 illustrates the vibrating bar 22 and ball-bearing in operative relation. In this figure the vibrating member is illustrated in a perpendicular plane, the line of motion whenever the said. bar is actuated being illustrated by the arrow. Pin 28 is preferably provided with an antifrictionroller to reduce the friction at this point, the same receiving any mechanical expression best suited to serve the purpose.

Fig. 3 illustrates the pawlcarrying lever suitably pivoted on a bracket at and )vided with spring 30, preferably supported by a springbarrel and acting normally to restore lever 29 to an elevated posillul]. The bracket 30", supportin the lever 29, has an arm 30 extending in a forward direction, and mounted on the said arm 30" so extended is a stop-pin 32, which stop-pin is adjustable in the perforations in the arm 30". On the pawl 34 and extending in a forwardly direction is the arm and in the ath of travel of the said arm 32 is the adpistable stop-pin 32, the function of which will be presently described. The cam-stop 31 is securely fastened to the pawl 34 and is preferably integral therewith, and mounted on lever 29 is a similar or companion camstop 31', the same being in operative relation to the cam-stop 31", mounted on the pawl 34. The spring 34 acts to cause pawl 34 to engage the toothed wheel 37* whenever the pawl-carrying lever is actuated. The platenshaft 37, suitably journaled on the carriage and carrying thereon the platen 37 and the ratchet-wheel 37, is constructed in any wellknown manner and callsfor no special description.

The action of the mechanism as above explained is as follows: The depression of the keys 34 to engage and rotate the toothed wheel 37, before explained. The return of the lever 29 1s in v rtue of the function of spring 30, carrying pawl 34, and with it the arm 32- In the path of arm 32 is the stop-pin 32, which acts to withdraw the pawl out of operative relation with ratchet 37 The upward travel of lever 29 is further prevented by the cam-stops 31 and 31 engaging: and also in virtue of the stop-pin 32 engaging the arm 32,.supported on awl 34. The adjusting of stop-pin 32 in a ower or higher hole will cause the lever 29 to be correspondingly adjusted for a greater or lesser travel. and therefore whenever the lever 29 has a greater throw the platen will be rotated for a plurality of spaces, and when the lever 29 is adjusted for a lesser throw the platen. will be rotated for a single space.

Fig. 4 illustrates a modification of the device employed to operatively connect the levers 1 and 40. In this figure the slotted member 39 has a key 39 mounted on the upwardlyextending end of said member. The pin 40 is securely fastened to the lever 40, the said pin being provided with anannular rim projected over the slot, which allows lever 40'to be actuated until the upper end of the slot comes into contact with the pin 40*. Spring 39* acts to restore member 39 to a normally elevated position. The lower end of slotted member 39 is provided with a suitable surface in order to rest on the lever 1 and when the said member 39 is depressed by key 39 to causc a corresponding depression of lover 1. The action of the parts ex 2 and 11 acts to cause the pawl plained above and illustrated in Fig. 4 is as and return the carriage, all that is required is to depress key 39, which acts to depress member 39 and to causes corresponding depression of lever l, the same acting to rot-ate the platen, the tjneniber 3Q continuing to travel in 21 downward direction until the upper limit of the slot 40" engages the pin tlfland' thereby the lever 40 is correspondingly depressed. The slot in member 39 acts also to allow the return of lever l independently and prior to the return of lever 40.

It willbc further clear that the arrangement of the parts in Fig. l and in Fig. allows the platen to be rotated independent of the return of the carriage and in any position of the carriage. The mechanism also allows the carriage to be returned indcpendent of the rotation of the platen by depressing key 41. 4
