TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Mar. 1, 1910.

To all whom it may concern:

Be it known that I, HERBERT H. STEELE, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- VVritin Machines, of which the following is a speei cation.

My invention relates to billing mechanism for typewriting machines and more particularly to mechanism for doing condensed record work.

One object of my invention is to provide simple and efficient billin mechanism operative to aid in mechanica ly positionin the platen and with the aid of which condensed record and other billin work can be readily done without taxing t ie mind of the o erator with mental calculations or the recol ection of given indices or numerals.

Another object of my invention is to provide simple and eflicient billing mechanism in the nature of an attachment which can be readily applied to existing forms of typewriting machines without changing the structural features of such machines.

A still further object of my invention is to provide billing mechanism for condensed record and other billing work ,in which the use of index numerals or indices may be entirely dispensed with.

To the above and other ends which will hereinafter appear, my invention consists in 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 corre sponding parts in the various views, Figure 1 is an enlar ed detail fragmentary sectional view of sufiicient number of parts of one form of typewriting machine to show the features of my invention in their application thereto, the section being taken on the line ww of Fig. 2 and looking in the direction of the arrow at said line. Fig. 2 is an enlar ed detail fragmentary end elevation showing a carriage mounted in place and the billing devices of my invention applied thereto. Fig. 3 is a detail transverse sectional view of a portion of the billing mechanism, the section being taken on the line m-a2 of Fig. 1 and looking in the direction of the arrow at said line. Fig. 4 is a detail transverse sectional view of a portion of the billing mechanism, the section being taken on the line 1 y of Fig. 1 and looking in the direction of the arrow at said line. Figs. 5, 6 and 7 are views corresponding to Fig. 3 but showing different relations of the parts. I have shown my invention applied to a Monarch typewriting machine to which my attachments may be readily connected without materially changing the structural features of said machine but it should be understood that the attachments may be applied to various styles of typewriting machines.

The top plate 1 of the machine supports upwardly extending fixed brackets 2 which support oppositely grooved carriage rails 3, -f secured to the brackets by screws 5. A rear carriage bar 6 has oppositely grooved guide rails 7 in which anti-friction balls 8 are received, the balls likewise cooperating with the oppositely disposed fixed guide rails 3 and 4 to support and guide the carriage in its movement from side to side of the machine. Extending forwardly from the rear carriage bar (5 near each end thereof are end bars or arms 9 which together with the bar 6 constitute the platen frame or carriage. These end bars 9 are provided with hearings to support a platen shaft 10 to which a rotary platen 11 is secured. The type bars (not shown) strike upwardly and rearwardly in the usual manner and impact against the platen at the front side thereof so that the printing line is always in view of the operator. The left hand end of the platen has a platen head 12 secured thereto by wood screws 13. the platen head being formed with crown teeth 14 which constitute a line spacing wheel. A deteut roller 15 is carried by a spring 16 secured by a screw 17 to an extension 18 on the left hand end bar 9 of the carriage. The. left hand end bar is formed with a bearing 19 therein through which extends a rock shaft 20. A fin er piece 21 is secured to the forward en of the rock shaft 20 and a crank arm 22 is secured to the rock shaft near the rear end portion thereof. A supporting arm 23 is loosely connected to move a limited distance relatively to a sleeve 24 received in the at 26 to the arm 23. The line spacing pawl is recessed at 27 for cooperation with the crank arm 22 and is adapted to be forced by said arm to contact with the teeth of the line spacing wheel and to turn the wheel and platen after such engagement has been effected. A restoring spring 28 is connected at one end to a bearing 29 in which the rear end of the shaft 20 is received and is connected at its opposite end 30 to the hub of the crank arm 22.

The line spacing mechanism described is more fully shown and described in the patent to Henry WV. Merritt No. 791,483, tiled June 6th, 1905 and constitutes no part of my present invention.

The parts thus far described are embodied in the Monarch machine and further description thereof is deemed unnecessary.

I will now describe the billing attachments of my present invention.

One end of a supporting sleeve 31 is received in an opening in the lefthand end plate or arm 9 of the platen frame and is secured therein by a set screw 32 which is received in a threaded opening in the end plate and bears at its inner end against the supporting sleeve. A sleeve-like extension or hub 33 on the left-hand platen head bears at its outer end against the inner end of the sleeve 31 andthus prevents longitudinal movement of the platen in one direction, whereas the platen shaft 10 extends through the sleeve 31 and receives a bearing therein.

A spring pressed locking device or latch 34 is ivoted at 35 to lugs or bracket arms 36 Which extend upwardly from and are secured to or formed as a part of a collar 37 which is received on the supporting sleeve 31 and is secured thereto by a set screw 38 received in a. threaded opening in the collar and hearing at its inner end against the supporting sleeve 31. An expansion spring 39 bears at one end against an extension 40 on the locking device and is received at the other end in a cut-out or opening 41 in the collar 37; the tension of the spring being exerted to move the upper end. of the locking device or latch 34 to the left in Fig. 1. The upper end of the locking latch is provided with a finger piece 42 by which it may be moved against the tension of its sprin to disen age it from locking position as wi l hereina ter more clearly appear.

Ad'acent to the locking latch is a socalle stop carrier 43 which is in the nature of a disk or shell and is provided with a stop 44 which, in the present instance, is in the nature of a pin that projects laterally from one face of the disk or carrier 43 and is riveted in place on said carrier. The in ncr edge of the cylindrical portion 45 of the shell is notched at 46 to provide teeth which 5 form a circular rack with which the locking device 34 is adapted to cooperate; an edge of the locking device being adapted to seat itself in any of the spaces 46 between the teeth of the rack and to lock the disk or shell a ainst rotation in either direction. The shell 43 is adapted to turn freely around the axis of the platen and on its supporting sleeve 31 when the latch 34 is disengaged from the circular rack on the shell in order that the stop 44 thereon may receive a rotative adjustment around the axis of the platen. A hub 47 on the shell 43 bears against the outer face of the collar 37 and prevents an axial movement of the shell in one direction. A collar 48 is supported on the supporting sleeve 31 at the other side of the shell 43 and is held in place by a set.

screw 49 received in a threaded opening in the collar and bearing at its inner end against said sleeve, to hold the collar in place with the inner face thereof bearin against the shell. 43 to prevent an outward axial movement thereof. The collar 48 is provided with an outwardl extending arm or stop 50. A second disli or shell 51 is arranged beside the shell 43 and bears at its inner face against the outer end of the collar 48 to prevent an inward axial movement of the disk. The disk 43 constitutes a rotary or oscillating carrier for a stop 52 which is in the nature of a pin that projects laterally from the member 51 and is adapted to contact with the

steps

44 and 50. The shell 51 is adapted to rotate around the axis of the platen and is provided with an ofl'set hub 53 which receives a bearing on the reduced portion 54 of a member 55 the outer end of the hub 53 hearing against the enlarged portion of the member 55, thus preventing an outward axial movement of the shell or disk 51 on its bearing. A spring 56 is contained within the shell or stop carrier 51 and is connected at one end to the stop 52 and has its opposite end connected by a screw 57 to the collar 48. The tension of the spring 56 is exerted to turn the stop carrier 51 in the direction of the arrow in. Fig. 3 to bring the stop 53 into contact with the stop 44 irrespective of the position to which said stop 44 may be adjusted by the rotative adjustment of the shell 43. It will be observed that the shell 51 constitutes a housing which surrounds or contains the spring 56, the stop 59, the stop 44 and the stop 52, all of said parts being inclosed by the shell 51. The shell or disk 51 is provided with an outwardly extending portion 58 having a central depression 59 with sloping or inclined walls 60 which constitutes a clutch member for cooperation with a correspondingly shaped clutch member 61 that is formed as a part, of a finger wheel 62. The finger wheel (r2 is in the nature of a sleeve that surrounds and moves longitudinally on the member 55 which is secured to the platen shaft by a setscrew (33 received in a threaded opening in the reduced portion of the member 55 and hearing at its inner end against. the platen shaft t and in a cut-out portion 6% therein. The set screw (13 may be introduced and see cured in place through openings 58. G and tilt formed respectively in the member 58. in the clutch. member of the linger wheel 62 and in the hub 53 of the disk 51. these openings being adapted to be brought into register with each other and with the screw receiving opening in the reduced portion of the member 55 to form a passage for the admission of the screw (33. A spiine (:7 is secured to the member and projects latcrally therefrom into a spline groove (38 in the finger wheel (13, thus forming a spline-d connection between the platen shaft and tinger wheel for locking the finger wheel against rotation relatively to the platen bat attording a movement of the finger wheel in the direction of the axis of the platen. The construction thus described ail'ords a movement of the finger wheel 2 longitudinally of the platen to effect a clutching engagement between the clutch members 58 and (31 in order to operatively connect the stop to the platen and to compel said stop to rotate with the platen. An expansion spring (39 surrounds the hub 51 and bears at one end a gainst the member 51 and at its opposite end against. the inner end of the finger wheel (32 so that when an inward pressure is released on the finger wheel the spring 69 will move the finger wheel in the direction of the arrow in Fig. 1. thus separating the clutch members and disconnecting the stop :32 from operative connection with the platen.

From the toregoii'ig description it will be seen that all of the parts of the billing device are arranged outside of the platen frame and are in the nature of attachments which can be readily applied to existing forms of typewriting machines. such as the Monarch. for instance, without modifying the structural Features of said machine. the screws 39. 4t) and ti?) holding all parts of the billing mechanism in place.

In the operation of the device it is necessary first to set the mechanism for the particular character of bill heads which are to be used in the machine. in order to do this it is neces ary to ell'ect a proper relative adjustment between the stops i-l and 50 which. in use. are in the nature of two lixed stops which cooperate with and limit the movement of the rotary stop 52. The stop 5; is arre ted in its ftll'Witltl movement or during its movement in the direction of the arraw in Fig. 2} by the. adjustable stop 44- and this stop it will therct'ore be termed the lin'ward stop whereas the buchward nnivement ol the stop 5; is arre ted b the fixed stop 50 and thi last mentioned stop will be termed the "back top The relative adjustment between the forward and back stops may be cilia-ted in the following inanncrz-lt may be assumed that the stops are in any position other than the correct one. such. for instance. 21 that shown in Fig. 3. A bill or invoice sheet oi the character to be used in the machine is inserted with its leading edge in the bighl between or at the intersection of the teed rollers ill and the platen. The shell :11 is then turned rtlarwardly by hand from the position shown in Fig. 3 and against the tension of its spring. or in a direction opposite to that indicated by the arrow in said ligul'e. until the rotary stop Yr carried thereby is brought into contact with the tixed back stop 5U as .-il('l\\'ll in Fig. 5. While the shell 51 i held in this position. the linger wheel oz should be forced in the direction opposite to that indicated by the arrow in l ig. l to eli'ect a clutching engagement between the clutch members and I'll. The opcrutor should maintain this' clutching engagement. by pressure exerted on the linger wheel. and at the same time turn the platen lor 'ardly to bring the desired point. say. the date line on the invoice sheet. to the printing line. In other words. the platen should he turned forwardly nntil the desired point on the invoice sheet is in position to receive the tire-t line ol writing. This may be readily determined in visible writing machine by the (iterator observing when the desired point on the invoice sheet is hronght to the printing line. the position of the paper rchr tivcly to the printing line being ctlnstantly under the observation of the operator in snch machines. in a bottom strike or blind machine it will be necessary to swing the platen back in order to observe when the proper point on the invoice sheet has be n brought to the printing line. The result of this forward movement of the platen is to turn the stop on to the position shown in Fig. tl. After thi positioning oi the invoice sheet has been eli'cctcd pre sure is still maintained on the linger wheel to keep the clutch members connected. and the tinger piece l2 is moved to the left to disengage the latch in order to tree the shell ill. The shell 4? is then turned rearwardly. or in a. direction indicated by th arrow in Fig. 6 until the stop l-l strikes the stop fr). This movement. of the stop it is from the position shown in Fig. (3 to that illustrated in full lines in Fig. 7. This relative adjustment of the stops gives the exact distance lOt) lit)

from the feed rollers 70 to the printing line hut as it is the custom to allow. say, three line space distances hclwecn entries on the record sheet: a further adjustment of the disk t l is etl'ectetl. "lhus. when the two stops ll and are in contact. as indicated in tall lines in Fig. i. the ling-1r wheel in reh-asial and the shell i is given a further liaclnvartl turning movement of. say. three teeth to tiring it to the position slnnvn in dotted lines in Fig. I and the shell in ltltjlit'tl in this po ition hr the latch Ill. This athli iional movement of the shell l2! corres 'iontls to three line soaring teeth of the ratchet wheel and is eitertcd in order to move the stops -l-t and 52 llilt'h' a tilt-tillh't. of three tine spaces, or from the full to the dotted line position shown in Fig. T and therchv provide proper spacing helwcen the ditl'ew cut entries on the condensed record sheet as will hereinafter more clearly appeal. The linger wheel is again moved to ell'ect. an engagement het ween the clatrh nieinhcrs and while the clutching engagement is main tained the platen is given a rearward niovcnient until the stop 5):! is hronght into contact with the fixed top [it]. "lhe linger wheel is then released and the spring 5t, will return the shill fit illlll the stop )2 uarried thereh to the normal position indicated in dotted lines at Fig. T where the stop 5; contacts with and i arrested lrv the top ll. The stops have now lwen set in proper relation to rotiperate with the particular character of hill heads or invoiee sheets to he employed and a l'nrther setting of the stops is tl11Iill" :11 Y until hill heads r invoice sheets of a dill'crcnl chara ter are to he used. "the c tnlensiial rcci'n'tl and cathon sheets may now he introelacwl into the machine between the invoice sheet and th platen. with the ttll'llili! sheet hetwecn the invoice and record sheets and the leading edges of the record and carbon sheets brought to the. hin'ht' h t ween the feed rollers and platen. 'lhe platen may now he turned forwardly to luring the proper point on the invoice sheet to the writing; line. The 1:|)- eizltur may then pr ceed to write the hill and during the writing ope 'ation the stop 3'3 will remain ltlt lti' its s 'iring' }'Irc sure in c ntact with the :nlju taizl t i'awarsl top ll. lhr stop 53 lining at thitime (list-inn nccted From the platen.

After the hill ha heen completed and reproduced through the interposed earhon on the record sheet the tinge]: wheel t'rl may he moved to the right to ctl'ect a clutching engagement hctwccn the clutch mcmhers. thus connecting the stop 52 to rotate with the platen. The platen is given a rearward rutation while the stop 52 i thus clutched to the platen and the extent ot rearward rotation of the platen is determined by the hackward movement of the stop which contaets with the fixed back stop and prevents further rearward movement of the platen. The clutch member may now he released and the pressure of the spring 56 will return the stop to its normal position in contact with its stop 44'. The extent of rearward movement of the platen thus etleeted is three line (spaces less than the distance from the printing line to the Feed rollers and consequently the last written line on the record sheet will. he returned to a point three line spaces in ad *ance of the feed rollers to provide proper spacing between different items on the record sheet. The written lIlYOltiL? sheet may now he removed with out disturhing the carbon and record sheets, or the written invoice sheet may he left in the machine and a seeond or a new invoice sheet intrmluccd into the machine in trout of or over the previously written invoice and with its leading edge at the point of in tcrsei'rtion ot' the teed rollers and the platen.

"lhe querator may then turn the platen forwardly unt l the date line on the last invoice sheet. introduced Into the machine is hronn'ht to the printing line. The operator may then proceed to write on the new invoice sheet and the items will be reproduced through the carbon sheet, giving a carlion cop or record on the condensed record sheet. The lirst line of the last written or second invoiec reci'ird on the condensed record sheet will appear three line space distances from the last written line ot the preceding record on the condensed record sheet. This operi tion may continue iiulelinitely and, when the invoice sheets are not removed from the machine a t'ter completing each of them the) may he fed hack and forth with the corn doused record sheet of carbon until they are t ed successively to a position where thev can he readil} rem ved front or rill he ted tor wartlly out of the machine. ith hill heads ol the size usually employed this occurs during! the writing of a third or fourth hill. In other words. when the third or fourth in- \oice sheet. has heen completed the first invoice sheet will he led to a position where it can be readily removed from the machine or n ill he fed entirely out" ot the machine.

hen one record sheet has been filled it may he removed troni the. machine, together with the carhon and such written invoice sheets as may he in the machine and, a new carbon and invoice sheet may then he introduced into the machine as before and the platen turned forwardly until the proper point on the invoice sheet. has been brought to theprinting line and the operator may proce d to write the invoice or the record, carhon and invoice sheet may he introduced into the niaehine with the leading edges I thereot together or the invoice sheet may be given a lead over the other sheets sufficient to bring the first hne of the carbon tit) copy to be reproduced on the record sheet near the top or leading edge of said sheet and thus avoid an unnecessary space at the top of each record sheet. It will be understood that after the stops are once set in position for use with a given character or bill head sheet, it is merely necessary to turn the platen torwardly to feed each invoice sheet up so as to bring the date line thereo't' to the printing line and to write the bill; then to actuate the clutch and move the platen rearwardly until it is arrested by the cooperation of the stops 52 and then insert the next bill as before and turn it. forwardly until the first line to be written thereon is brought into register with the printing line, and so on the operation may be continued indefinitely.

From the foregoing description it will be nnderstoml that there are no means for arresting the platen in its forward rotation, that this is determined wholly by the operator observing when the proper point of the invoice sheet has arrived at the printing line but that the platen is positively arrested in its rearward or backward movement for the intrmluetion of a new invoice sheet; that the extent of rearward movement of the platen when the clutch members are engaged. ls determined by the movement of the stop 52 from its norn'ial position in contact with the stop ll to the tired or back stop 5t), and, that the adjustment of the stop -l-l regulates the extent of the rearward movement of the platen. it will also be seen that l have provided simple and etlieient billing mechanism to aid in produeingthe condensed record work and by whirh the platen may be mechanically positioned in its backward movement or by which the platen may be moved rear wardly a predetermined extent or to a predetermined point, and that the platen is free to li'iflYe tornardl) any desired extent: and that there is no necessity for referring to indiees or making mental calculations in the operation of the billing devices in order to actuate them for condensed record work.

Various cl'ianges may be made without departing from the spirit and scope of my ire yention.
