TYPE-WRITING MACHINE.

Specification of Letters Patent.

PatentedJuly 12, 1910.

To all whom it may concern:

Be it known that I, HERBERT H. STEELE, a citizen of the United States, and resident of Marcellus, in the county of Onondaga and State of New York, have invented certain new and useful Im rovements in Type- \Vriting Machines, 0 I which the following is a specification.

' My invention relates to typewriting 'machines and more particularly to billing mechanism.

In most instances condensed record billing work does not require more than a single rotation of the platen in order to bring a newly introduced invoice sheet to proper position to receive the first line of writing. However, it sometimes occurs that the printed headings on'the invoice sheets are so deep that it requires morethan a rotation of the platen to bring a newly introduced sheet in proper position.

The main object of my present invention is toprovide a comparatlvely simple and eflicient mechanism that will aiford more or less than onerot ation of the platen, as may be desired, before it is arrested by the billing stops.

The present invention is shown applied to a billing typewriter in which the turning of the platen to introduce the new sheets of paper is efiected by means of the ordinary finger wheels at the end of the platen shaft. here the heading of the bill is of such depth as to require the platen to be turned more than half of a rotation it requires two operations to turn the platen in thesedevi'ces as heretofore constructed. The operator cannot turn the platen much more than half of a turn at one gripping of the hand on the finger'wheel. By the present invention nearly or quite a complete rotation can be imparted to the platen by one gripping of the finger'wheel. This is a matter of a good deal of convenience and of time,

-A further object-of my inventionis to provide mechanism of the character specified which is applicable to existing forms of typewriting machines without modifying, or materially modifying, the structural features of such machines as they now exist.

A still further object of my invention is to embody the features thereof existing forms of billing mechanism without modify.-'

it saves a good deal the features of construction, arrangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicate correspondin parts in the various views, Figure 1 is a ragmentary vertical sectional view taken through one end of the platen and the associated billing devices. Fig. 2 is an end view of a carriage withparts broken away, the carriage bein shown equipped-with the billing devices 0 my invention. Fig. 3 is a view corresponding in part to Fig. 1 but showing amodified form of construction. Fig. 4 is a viewwhich corresponds to Fig. 3 but shows a'still further modification of the invention. Fig. 5 is a detail endview with parts in section, the view showing portions of the clutch mechanism by which the billing stops are rendered operative or inoperative to arrest the platen.

The invention in the present instance is shown embodied in a Monarch typewriting machine and may be said to be in the nature of an improvement upon the construction disclosed in the patent to Jacob Felbel No. 902,527, dated November 3rd, 1908 and also upon the construction disclosed in my application Serial No. 520,684, filed October 22, 1909. It should be understood, however, that the invention may be embodied in various styles of typewriting machines and that various changes may be made to facilitate such embodiment.

Fixed oppositely grooved guide rails 1 are secured to the top plate of the machinein the usual manner and receive anti-friction balls or rollers 2. The supporting and guide rollers 2 are likewise received in op:

positely grooved faces of a slide or guide bar ends with finger wheels 6 secured thereto by set screws 7. 'A cylindrical rotative platen 8 is mounted on and operatively connected to the platen shaft in a manner to be hereinafter described. A cross bar 9 extends above the laten and is connected at its ends to upwar 1y extending bracket arms 10 formed on the end lates 4 of the carriage. A bracket plate 11 is provided with an upwardly extending ear 12, secured to the frame of the carriage by a screw 13 which is received in a tapped opening in the end of the rod 9 and is operative to secure one end of the rod in place on the bracket 10 as well as to secure the plate-like bracket 11 in posi tion. The rear end of the late-like bracket 11 is secured to the rightand end plate. 4 by a screw 13 and a bracket 13. A shouldered screw 14 passes through the bracket plate 11 and into a tapped opening in the right-hand end plate and constitutes a spindle or arbor for a sprocket wheel 15. The bracket plate 11 is provided with upwardly extending arms 16 and 17 to which a stop carryingvbar or rod 18 is secured by screws 19. The rod or bar 18 is or may be, rovided with a scale 20 to facilitate the ad ustment of an adjustable stop 21 which-is carried by the stop bar 18 and is secured in its adjusted position thereon by a set screw 22.

The forward end portion of the bar 18 is provided with a fixed stop 23, which projects rom the right-hand face thereof. A sliding stop 24 surrounds the stop bar and is connected at 25 to an endless band or chain 26 that extends around and cotiperates with the sprocket wheel 15. The sprocket chain also extends around a driving sprocket wheel 27 adapted to be operatively connectedwith the laten shaft in a manner which will hereinafter more clearly appear. ,It will be understood thatwhen the endless band or chain is operatively connected to the platen shaft a like connection is effected between the platen shaftand the movable stop 24 so that as the platen shaft rotates a rectilinear movement will be transmitted to the traveling stop24 to move it between the fixed stop 23 and the adjustable stop 21.

O erative connection between the platen sha t and platen is effected through a train of covered reduction gearin which in the present instance, transmits rom the platen shaft to the platen two'complete rotations of the platen for one rotation of the shaft. This reduction gearing comprises a bevel gear 28 provided with a hub 29 received in an opening in the right-hand end plate 4 of the carriage and fixed in osition 1n the end plate by a set screw 30 w ich is received in a tapped opening in the end plate and bears at its free end against the hub of the gear. This gear is therefore fixed to the carriage and is concentric with the platen and receives and constitutes a bearing for the platen shaft 5 which extends therethrough. A corresponding bevel gear 31 is likewise arranged concentric with the platen and is provided with a hub 32 received in, an inwardly extending hub-like portion 33 on the right-hand platen head 34. A feather or in 35 is-received in registering openings ormed in the hubs 32and 33 to lock the gear 31 to rotate with the platen. The platen shaft 5 extends ceritrally through the gear 31 and receives a bearing therein so that the platen and platen shaft may turn one relatlvely to the other. A cruciform carrier 36 is mounted on the shaft 5 and has one of its hub-like arms 37 tapped to receive a set screw 38, which at its inner end, engages a flattened portion 39 on the platen shaft to connect the carrier rigidly with the platen shaft. The hub- like arms 40 and 41 of the carrier receive the platen shaft whlch extends through the carrier and is surrounded by it. The fourth arm 42 of the carrier is provided with an annular shoulder 43 against which one face of a beveled planetary gear 44 is ada ted to bear. The arm 42 is likewise provi ed with a reduced portion 45 which constitutes a spindle on which the gear 44 is ada ted to turn. A headed screw 46 is received in a tapped opening in the spindle of the arm 42, the head of the screw overlapping the end of the hub 47 of the gear to hold 1t in place on the spindle. This gear 44 meshes with and constantly engages the twocooperating, gears 28 and 31 so that a rotation of the platen shaft is effective to turn the carrier 36 and thereby carry the planetary gear 44 around the platen shaft as a center. This movement of the planetary gear likewise produces a turning movement of said gear on its spindle 45 by reason of its engagement with the fixed gear 28. The rotative movement of the lanetary gear 44 around its spindle 45 pro-" duces a rotative movement of the platen around the platen shaft. As hereinbefore pointed out this rotative movement of the platen in thepresent instance is as two to one, two revolutions of the platen being eflected for a single revolution of the shaft.

The means whereby the platen shaft is operatively connected to and disconnected from the sprocket chain or the traveling stop 24, ma be of any suitable construction. Anysuitab e two-part clutch for instance,

jmay be employed for this purpose. The

construction disclosed in the present instance 1s one such as is shown in my application hereinbefore referred to and in pracllt tice I prefer to employ such a clutch. A

shouldered sleeve 48 is received in an opening in the bracket plate 11 and is secured therein by a drive fit orotherwise. This. sleeve constitutes a bearing for the platen shaft which extends therethrough and the outside ofsaid sleeve likewise constitutes a bearing for a hub 49 formed as a (part of a shell or housing 50 which surroun s the cooperativeclutch members. The hub 51 of the driving sprocket wheel 27 surrounds the I hub 49 of the housing 50, the hubs 51 and 49 being secured together by any suitable means. The housing 50 is formed with an annular cut-out to receive a ring 52 provided with inwardly extending oppositely beveled clutch teeth 53. The'rlng 52 bears against a shoulder or flange 54 to which the ring is secured by pins 55. Radiallydisposed sliding clutch members or pawls 56 are received and slide in grooves 57 formed in a member 58 secured to the platen shaft by a pin 59 which extends through an opening in a hub 60 of the member 58 and through the platen shaft, to fixedly connect the two to rotate together. Each pawl 56 is provided with an inwardly extending pin 61. Three triangularly arranged coiled springs 62 are connected at their ends to these pins and tend to draw them inwardly. A frusto-conical actuating device or wedge 63 is provided with an enlarged central opening 64 through which the platen shaft 5 extends. The inclined face 65 of the actuating device coiiperates with and is supported by the inner ends of the radially disposed pawls 56 and when pressure is exerted upon the wedge or actuating device the pawls will be forced outwardly into engagement with the teeth 53, thus rigidly connecting the member 58, which is fixed to the platen shaft, with the member 50, which is fixed to the driving wheel 27. At this time, therefore, t e driving wheel is locked to the platen shaf to rotate therewith and to cause a movement of the traveling stop 24 between the steps 21 and 23.

Pressure is maintained upon the wedging or actuating device 63 by a spring-pressed slide 66 which is mounted to slide longitudinally along the platen shaft and bears at one end against the wedge 63. A coiled expansion spring 67 surrounds the platen shaft and bears at one end against the slide 66 and at its opposite end against the bottom of a cup-like member 68, the cylindrical portion 69 of which surrounds the coiled spring. The bottom of the member 68 bears against the hub of the right-hand finger wheel to limit the movement of the member 68 to the right. Theslide 66 is provided with a circumferential flange 70 against which one side of a circular portion 71 of a lever 72, is adapted to hear. The circular portion of the lever 72 enables the platen shaft and the slide to extend through the lever and provides an effective engagement for the lever on the slide 66. The rear end of the lever is pivoted by a bolt 73 to a of the lever 72 is provided with a finger the movable stop 24 controlled thereby. A

latch 76 is pivoted by a headed shouldered screw 77 to an extension 78 on the forward end of the bracket plate 11. The latch is provided with a finger piece 79 by which it may be depressed against the pressure of a suitable spring (not shown) in order to disengage the engaging portion 80 of the latch from the release lever 72. When the latch engages the release leverthe latch is effective to lock the lever in its clutch-releasing position so that the platen may be turned indefinitely independently of the stop devices.

Referring to the modification shown in Fig. 3 it will be observed that in addition to the parts previously described I have provided a fourth bevel-gear 81 which is situ-v ated opposite the gear 44 and like the gear 44 is adapted to turn on a spindle 82 formed on an arm 83 which corresponds to the arm 37 in the construction previously described. A headed screw 84 is received in a tapped opening in the shaft 5 and performs a twofold function, the inner threaded end of the screw engaging the shaft to lock the carrier to rotate therewith and the head of the screw overlapping the end of the hub 85 of the gear 81 to prevent a displacement ofthe gear 81 from its spindle and at the same time to provide means for efiecting an adjustment of the gear 81 toward the oppositely disposed gear 44 in order to compensate for any lost motion or back lash that may take place between the gears 28, 31 and 44. This arrangement also provides for abetter distribution of the forces on opposite sides of the platen shaft in transmitting movement from the shaft to the platen. Moreover, the arrangement greatly reduces the liability of any looseness or lost motion in the train of gearing.

In the construction disclosed in Fig. 4 a

coiled expansion spring 86 is interposed beit is believed, for describing the operation thereof further than to point out that when the clutch members are in engagement the platen will be arrested in its backward movement by the engagement of the traveling stop 24 with the forward stop 23. A bill or invoice sheet is then introduced and a forward rotation of the platen is effected, thereby producing a rearward movement of the traveling stop 24 along the bar 18 until the traveling stop engages and is arrested by the adjustable or back stop 21, thus arresting the platen in position to receive the first line of writing on the newly introduced invoice or bill sheet. The clutch may then be disengaged and the writing proceeded with. During the operation of the usual line spacing mechanism the platen will be rotated at successive line spacing movements and the effect of these movements is to turn the planetary gear and-effect a corresponding movement of the platen shaft. The clutch sec tions at this time, however, are disconnected, and the turning of the platen will not affect the stop devices.

The gearing may be protected from dirt by a cylindrical cover 89 having an opening 90 for the insertion of the bit of a screw driver when it is desired to turn the screw the laten so as to obtain register of the holes wit the screws of the gearing. The cover may however be fixed and the platen rotated to bring the screw into alinement with the hole.

While I have referred to the train of gearing between the platen and stops, and between the platen and platen shaft or the finger wheel thereon, as reduction gearing, inasmuch as there is a reduction of the speed of two to one between the platen and said parts, it will be understood that regarded the other way about or fromthe traveling stop or from the shaft to the platen, the intermediate gearing may .be regarded as multiplying gearing WhlCh increases the speed of the p aten two to one with reference to the traveling stop or the finger wheel.
