TFatent-ed May 3, 1910.

Application filed February 21, 1908. Serial No. 417,132.

To all whmrrit may concern:

Be it known that I, Enoan ll. Bunny, citizen otthe United States, and resident of the borough of Brooklyn city of York, in the county of Kings and State of New York. have invented certain new and useful improvements in Type-lvriting lilachines, of which the following is a speci: cation.

My invention relates to typewriting machines and more particularly to line lock and alarm and margin stop mechanism and the main object of my invention is to provide improved mechanism of the character specified.

To the above and other ends which will hereinafter appear, my invention consists of: the features of construction, arrangements of parts and combinations oi" dcvices to he hereinafter set forth and particularly pointcd out in the appended claims.

in the accompanying drawings wherein like reference characters indicr e corre sponding parts in the various views, Figure l is a vertical front to rear sectional view of a typewriting machine embodying my invention. Fig. 2 is a trontelevation of the same with parts in section. Fig. 3 is a tragmentary top plan view of the same with the parts sectioned away.

Fig. 12 is an L connected hy a link enlarged detail top view with parts in section showing the final stop associated with the margin stop and some of the-parts that cooperate therewith. Fig. 13 is a sideclevalion partly in section showing the alarm mechanism.

l have shown my invention in the present instance applied. to a front-strike typewritin; u'iachinc similar to that disclosed in the ication of Oscar Yi oodward, Serial 2H, 98'. filed August. 15th, 1905, but it should he understood that the invention may he embodied in various styles of typewriting machines.

The frame of the machine comprises a base 1, corner posts 9 and a top plate 3. Fixed rails 4t and 5 are supported on upwardly extending; lugs G which project from the top plate. The rails l and 5 are grooved for cooperation with anti-friction balls or rolle s 7 which are received in correspondingly grooved r: 'ls S and t}, which constitute the rear and forward cross bars respectively of a rectangular carriage or truck, said cross liars being united hy end bars 10. A platen 11 is supported by the carriage in any suitable manner.

llairwardly extending arms 12 are piv- I oted at 13 and carry atv their rear ends a feed rack 1% which cooperates with a feed pinion 15 on one end of a shaft. which turns in a tired hearing 16, the rear end of the shaft, being operatively connected to an escapemcnt wheel 1?. Feed dogs 18 cooperate with the escapenicnt wheel and are carried by a dog rocker 19 pivoted at 20 in bracket arms 21 which extend from the de ending hracl t secured to the top platev A forwardlyhxtending arm 23 on the dog rocker Zl with a crank arm which projects from a rock shaft 26 pivoted at its ends in the base of the machine. Crankarms 27 likewise extend from the rock shaft and are connected by depending links 28 to a universal bar 29 which extends transversely of the -machine beneath the set of key levers 30 pivoted at their rear ends on a fulcrum plate 31 and providedat 36. The type ears are pivoted on hangers at segmentally arranged on type har scg nients 38. The forward ends of the type bars are supported on a pad 31) whichresls upon a"segment 4-0 having a depending flange 41 which supports hungcr.- 42 for the sub levers 3 t. Zach ol the key levers is provided with an engaging portion or hooklike projection 13 near the forward end thereof. A locking bar l l; is provided at its ends with ears 45 by which it is pivoted at 46 to the base of the machine above the system of key levers and over the engaging pro- .jections 43 on the key levers. The lower portion of the locking bar extends rear- Wardly to form a flanged? which is adapted to pass under the projections or engaging portions 43011 the key levers and to lock them against printing depression or against an extent. of depression which will all'ord printing operations of the type bars. From an inspection of Fig. 5 it will be observed that the locking bar is provided. with a for-- cured at one end to the rock shalt wardly extending arm 48 hook-shaped at its forward end as indicated at 49 for cooperation with a depending crank arm 50 on a verticalrock shaft 51. The crank arm 50 is preferably in the nature of a wire seand engaged by a contractile spring secured at one end to the crank arm and at its opposite end to a. pin projecting from the lived 0o portion of the machine. The rock shall; 50

extends through an opening in the top plate and is situated adjacent-to the left-hand forward co'rner post of the machine. The lower end of the rock shaft is received in a bearing in the base of the machine, whereas the upper end of the rock shatt turns in the bearing in the forward lixed guide ail 5. The upper end of the rock shaft 51., where it extends above the top plate, has a crank arm adjustably secured thereto by a set screw 55. The crank arm is pivotally connected to one end of'a link 56 which extendstransversely of the machine and has a longitudinal moven'ient in a 5. The link extends to of the machine where it is bent. forwardly at 57 and is received in an upright slot 58 in a stop member designated as a whole by the reference number 59. This stop member comprises an upwardly V or stop portion (30 located about centrally ot the machine and at the forward portion thereof and is provided with a finger piece 61 by'jWhich it can be readily manipulated from 'thefront-of the machine by the operator. The stop member has a sleeve 62 driven with adrive tit on'the contracted portion 63 of a cylindrical carrying meinber or trunnion-like pivot (34, the sleeve (32 abutting a shoulder 65 formed at the intersection of the enlarged and contracted portions of the carrying member 64. The earrying member 64 and the stop proper 60 to gether with-the finger pity-e 61 thus constigroove in the fixed rail about the center extending engaging I: l l i l l l i l l l l l wvhere the flange 47 thereo'l. wi

thou h l prel'er to form them in the main ncr tescribcd to facilitate manufacture and assembling. The le'l't-haud end of the carrying member ti-l ol' the stop may be recessed to receive a coiled expansion vspring till one end of which is connected to the carrying n'ieniber at til, the other end oi. the spring being secured at (38 to a cylindrical block (39,-.

The stop 5i cxtcnds at its top and bottom through a slot T0 in a cylindrical housing Tl. secured to the forward sidc ol the lived guide rail 5 by screws 7;. 7 The slot it) ail'ords a movement of the stop in two directions at substantially right angles to each other one direction being in the general direction of the travel ol' the carriage and the othe at substanliall) right angles thcrcto. The reduced portion 625 ol the stop carrier is received andhas a bearing in an opening it in the c vlimlrical housing Tl. whcreas the enlarged portion of the arricr is re ccived and has a bearing in an opcning T5 in the housing. I

The block till hercinbetore rcl'crrcd to has a screw-driver nick Ttl at its outer end to enable the block to be turned in order to appl a torsional st ain to the coiled spring on. An opening extends trunsvcrsetv through the cylindrical block and the screw Tl; passes t'rccly through said opening to secure th block in place after torsional strain has been placed upon the spring on llv this construction the spring tltl is employed tor a t\\o-i ,old purpose. 1'. c., to turn the stop 5! around its pivotal center of its carrier in the housing it so as to bring the upper or top engaging portion (30 ot the stop into the path of the cooperating stops on the carriage as shown in Fig. 7, and at the same time to normally maintain the stop toward the right as indicated in big. it) and to restore it to this position utter it has been moved to the left as will hereinal'ter more clearly appear.

It. will be understood that the pin and slot conl-icction 5T 58 between the line lock stop fill and the line lock mechanism ii'tloi'lls a pivotal 'niovcmcnt ol' the stop l'rom the full to the dotted line positionshown in Fig. 7 or vice versa without a ll'ccting the line lock mcelmnism. \Vhcu, however, the stop (it) is moved to the left. a longitudinal movement of the link 56 is ell'ccted thereby turning the rock shaft '51. against. the tension of the spring 52 to enable the loci-:ing bar l-l to move by gravityto the inking position be situated beneath the engaging projections 13 on the key levers, thus locking the key levers against printing depression.

Near the. right-hand end of the carriage and at the forward side theredt is carried a line lock stop designated as a Whole by the reference numeral 7 7. To the right of direction of the travel of the carriage but cannot be detached from the carriage. The left-hand end of the block 99 is formed with a pointer 110 for cooperation with the a carriage scale 91 and said pointer is adapted to be brought into register with the pointer or indicator 93 on the line lock stop 77 so that both indicators may if desired, be brou ht into register with the same index on tie carriage scale as shown in Fig. -l. W'hen the parts are in the positions shown in Fig. -lnot only are both of the

pointers

93 and 110 brought into coincidence to register with the same index on the carriage scale but a portion of one stop adapted to overlap the other, as shown in said figure and in 1*ig'. (3. in order that both of the arresting faces 80 and 100 of the two stops may be brought into coincidence to cltcct eo 0 operation with the line lock stop 59 at the same time. The construction of the line lock be moved around its pivotal center to clear the final stop as will be, understood from an inspection of Fig. 7-. If, therefore, the two stops 7? and 78' be adjusted at the same index mark on the scale this will be a final pointofyarrest or the final point and only pointat which the carriage can be locked out of o eration and additional letters or a hyphen cannot be inserted unless the final stop is moved to the right. If, however, it is desired to enable the operator to sort a predetermiueil number of charactms after .the initial ine locking. this may be eti'eeted by first setting the'final line lock stop '78 a predetermined distance from the stop 77.

If. for instance. the stop 78 be located four letter space distances from the stop 77 on 0 the carriage scale, then four additional charactersmay be inserted after the line lock stop 77 is reached and released and before the machine is tinally locked out of operation by the linal stop 78. e

.A marginal stop designated as a whole by the reference numeral 111 is .)rovided near the lefthand end of the carriage and at the front thereof where it. is readily ac cessible to the operator, and to the left of this margin stop a final margin stop designated as a. whole by the reference numeral 112. These stops 111 and 112 are construct'ed like the

stops

77 and 78, respectively, except. that they are reversed and a detail description of the stops 1.11 and 112 is deemed unnecessary. In the use of the stopsll'l and 112 the margin stop 11.1 is first. brought into contact with the stop ()0 in the movement of the carriage from left toright but no movement of the stop is effected at this time. inasmuch as it is at this time pressed to the limit of its movement.- to the right by the spring 66 and an arrest of the carriage is therefore etfected. Should 5 the operator desire to write within the marstop 78 is such that the stop 59 cannot gin it. is merely necessary to press the finger piece (31 rearwardly, thus moving the stop 59 out of the path of the engaging portion of the stop 111 and the operator may write beyond the normal margin determined by the stop 111; the distance beyond the normal margin within which Writing can be produced being determined by the relative adjustment between the stops 111 and 112. When the stop 111 is -to the right of the stop 59 and a movement of the carriage from right to left takes place a bevel on the stop 1, corresponding to the bevel 9S on the stop 77, will force the stop 51: around its pivotal center. thus enabling the stop 111 to pass to the left of the stop 59.

' In order line lock mechanism is actuated I have provided alarm mechanism which is best shown in Figs. 1, 2, 3, 11 and 13 from which it will be seen that a bell 113 is secured to the forto warn the operator before the i ward right-hand corner post of the machine by a screw 11%. A bell hammer 115 cooperates with the bell and is mounted on a. carrier 116 formed at its upper end as a root; shaft 117 received in a groove in the bottom of the forward fixed rail 5 of the'n1a chine. This rock shaft is provided with a forwardly extending arm 118 which extends beneath an actuating leyer or bell trip 119 pivoted at 120 in a cut-out 121 in the fixed rail 5 and extending through the cut-out and beyond the upper face of the rail as shown in Figs. 11. and 13. This lever 119 carries a pawl 122 having a rounded portion 123 received in a C-shaped bearing 124- of the lever 119 so as to atl'o'rd a turning movement of the pawl 122 independently of the lever 11? leaf spring 125 is secured at 126 to the lever and bears at its free end against the against a face 127 of the C-shaped-bearing portion of the lever to normally retain the pawl and lever in fixed relation. The pawl 122 is beveled at 128 on the upper right hand side thereof for purposes which will hereinafter appear. This pawl isinthe path of'the engaging portion 80 of the lineloek stop 77. As the carriage moves to the left the engaging portion of theline lock stop will'be brought into contact with thefcam face 128 of the stop reaches the stop 59. The effect ofthis contact is to move the left-hand end of the lever 119 downwardly, thus rocking the shaft 117 to move the bell hammer-from the dotted to the full line position shown inFig.

i 13. \Vhen the line lock stop passes the pawl 122 the parts of the bell trip and alarm mechanism will be restored to-,th e1r normal positions and the bell hammer 115 will vibrate against the bell sounding an alarm, prior to the time the line lock stop actuates the line lock mechanism. In the movement of the carriage b ck to the right the line pawl 122 to hold it normally Pa-wl 122 before the line lock i esaem this stop is What is termed a final line lock .stop designated as a whole by the reference as will hereinafter'more clearly appear. The block 79 is provided with a thickenedorenlarged portion 8lreceived in therear of a depending flange or retaining strip 82 on a bar 83 secured by screws 84- to the front. cross bar 9 of the carriage. A rack with square teeth 86 is interposed between the bar 83 and the cross bar 9 of the carriage and is secured in place by the screws 84. which The teeth of the rack 85 extend forwardly for eotipera tion with teeth on the line lock stop,

theseteeth being situated at one endq'iortion "of the stop on the flange or enlarged portion 81 thereof. The forward wall of this onlarged portion is inclined indicated at 88 to provide a space between the retaining strip 82 and the enlarged portion of the stop. A leaf spring 89 is secured at one end as at 90 to the line lock stop and bears at its opposite free' end against the rear face of the re taining strip 82 and tends to press the righthand or tootlrbearing portion of the stop toward the teeth. of the rack 85. The forward face of the line loch sto; has a. sheet metal piece of plate 01 secured thereto by screws 92. An upwardly projecting pointer '03 extends from the piece 91 for cooperation with a carriage scale M carried by the carriage. The plate 91 near the lefhhand end of the line lock stop is provided with a finger piece by which the stop ma y be released from engagement with the rack 85 for adpistment 1n the direction of the travel of the carriage as will hereinafter appear.

From an inspection of Fig. 8 it will be seen that the rearside of the enlarged portion 81 of the line lock stop forms an inclined face 96 which between the teeth andthc linger piece 95 has a rounded hearing portion or projection 97 that normally bears against the rack or the'teeth thereon and; constitutes a fulcrimi on which the stop may be turned against the tension of the spring 8t) from the full to the dotted line position, thus enabling the stop to be disengaged from the rack and adjusted longitudinally or in the direc tion of the travel of the carriage, the pointer 93 cohperating with the carriage scale to properly determine the position of adjustment of the line lock stop. It will be seen from an inspection of 'Fig. 8 that the engagline loch stop will be brought into engagement with the stop 59 on the fame of the machine, moving it in the direction of the axis of its trunnion-like pivot G36 L to the left \with the carriage against the tension of the spring (36. This movement is effective to transmit a longitudinal movement to the link 56 which turns the rock shaft 51, thereby moving the c 'ank arm 50 rearwardly against the tension of its spring 52 to enable the locking bar 44 to drop by gravity to the locking position where the flange 47 on the bar is interposed in the path ol. the projections 43 on the key levers, thus preventing printing operations thereof and locking the machine out of operation. Should the operator desire to release the line loch mechanism in order to write one or more additional characters in order to .complctc a word or to insert a hyphen, the linger piece (31 may be pressed rearwardly, thus turning the stop 59 on its tinnniondilte pivot (33-434: and moving the upper engaging portion of the stop 59 from the full to the dotted lino position shown in Fig. 7, thereby carrying the stop 59 out of the path of lhe line locl; stop 77 and the stop 55) will he returned to normal position by its spring (iii. In the return movement of the carriage the beveled portion 98 of the line lock stop 77 will engage the arresting portionol) of the stop 5i), deflecting the arresting portion forwardly to the dotted line position shown in Fig. 7 to enable the line lock stop 77 to pass to the right of the stop 59.

The so-called tinal line lock stop 78 hereinho't'orc referred to is situated to the right of the line lock stop 77 and is shown in de tail in Figs. l, (3, 7, 5) and i2. From these figures it will be seen that the final stop designated as a whole by the reference numeral 78 conn'irises a block or stop carrying portion 00 having an arrest ing face 100 that extends into the path of the stop 59 as shown in Fig. 7. The body of the stop 78 is pcrforated to provide a hearing for a pivot 101 of a releasing device having a finger piece 102 lixcd lo the pivot 101 and having a de pending end 103 rorcivcd in a cut-out or opening 104 in a locking slide 105 provided at its rear end with teeth 106 which engage as a flange or enlarged portion 109 received back of the depending retaining strip or flange 82 on the bar 83 hereinliefore referred to. moved rearwardly the locking slide is disengaged from the rack 85 and the stop 78 may be moved to right or left or in the When the finger piece 102 isthe left hand straight face 129 on the pawl stroke onthe bell.

122 and will turn it on its pivotal center 123 against the tension of its spring 125 without vibrating the lever 119, and the alarm will not be sounded. As the line lock stop passes to the right of the pawl 122 said pawl will be forced back to its normal position relatively to the lever 119 by the spring 125, and the parts will again be in position to sound the alarm-when the carriage is moved to the left.

, The means for applying spring pressure to the bell hammer and the associated parts are best shown in Fig. 13 where it will be seen that a device or lever 189 is pivoted at 131 to the right-hand for ard corner post of the machine and is connected to one end of a spring 132, the other end of which is connected to the arm 116 of the bell hammer. The device 130 carries, at the other side of the pivot 131, a screw stop 1355 provided with a knurled head 13% by which the stop may be adjusted to regulate the normal position of the pivoted device 130, it being understood that the end of the screw bears against the right-hand forward corner post. 2 of the machine to limit the movemeni'x of the pivoted device 130 in one direction. As the screw 133 is turned forward from the posit-ion shown in Fig. 13 the. upper end of the pivoted device 130 will be moved to the right and an increased pressmre will he applied to the parts by expanding the spring 132 so that greater force will be applied to the bell hammer to increase the force of its 3y these means the power of the alarm or the force of the stroke of the bell hammer on the bell may be increased or decreased atwill. A fixed pin 135 extends in the path, of the lever 119 to limit its upward movement and thus enable it to be properly interposed in the path of the line lock stop. From an inspection of Fig. 7 it will be observed that the engaging portion 100 of the final line lock stop is out of the path of the pawl on the bell tr p and consequently does not co-act therewith so that the alarm mechanism is only actuated by the line lock stop 77.

From an inspection of Fig. 1 it will be seen that the cylindrical bearing piece or housing 71 for the stop 55) is extended rear- Wardly at 136 to form a supporting bracket for a pointer 137 secured to the projection or bracket by a screw 138. The pointer is bent upwardly and then forwardly around the front cross bar of the carriage and cooperates at its forward end with the carriage scale 94:.

From the foregoing; description it will be seen that all of the

stops

77, 78, 111, 112 and 59 are located at the front of the machine where they are readily accessible to the operator for adjustment and manipulation and Where the stops 7?, T8, 111 and 112 co-act with the carriage scale which is at all times in the View of the operator so that the stops may be readily set by said scale to determine the desired points of engagement. between said stops and the stop 59 and that the stop 59 is so positioned that it may be readily actuated by the operator to release the line.

locking mechanism or to enable the carriage to move beyond the normal margin deter mined by the margin stop 111.
