TYPE-'WRITING MAC HINE,

Specification of Letters Patent. Patented-June 1913 Application filed January is. 1913. Serial no. 742,341.

:Beitikiimvn that I, HERBERT H. SrEELn, citizeirof the United States, and resident of Marcellus, in'the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- WritingMachines, of which the following is a specification.

My invention relates to type-writing machines and more particularly to tabulating mechanism. 1 One of the objects of' my invention is to. provide a comparatively simple and efficient two-way tabu'lator' by which a tabulating' operation may be effected by a backward movement of the carriage, as well as by a forward movement thereof in the direction of its feed. Another object of my invention is to provide novel means by which the carriage may be arrested at the same letter space position, whether a backward or forward tabulation is effected. I

A further object of my invention is toprovide novel means for holding the carriage-againstmovement which would tend to separate the tabulator stops when an arrest of the carriage isefi'ected by said stops.

A still further'object of my invention is to provide means of the character specified above that may be readily embodied in existing styles of typewriting machines without modifying, or materially modif s 'ing the structural features of said machines as they 35.

now exist.

To the above and other ends which w ll hereinafter appear, my invention consists one of the. denominational stopsand its ass ci-ated latch.' Fig. 4 is a fragmentaryplan view, .withparts. in section, the View showing a portion of the tabulator mechanism and some of the associated parts. Figs. 5 and 6' are enlarged detail diagrammatic plan views of the tabulator stops. Figs. 7 8, 9 and 10 are fragmentary diagrammatic feed pinion and feed rack, the different views showing the parts disposed as they appear under different. conditions of use.

I have shown my invention embodied in the present instance in' the Monarch machine in which the invention may be readily included without modifying, or materially modifying, the structural features of that machine as they now exist. It should be understood, however, that the invention may ing machines.

base 1, corner posts 2 and top plate The carriage comprises a cross or slide bar 4 from which end bars 5 project forwardly to support a rotati e platen 6. The slide friction balls or rollers wluch are received in oppositely grooved guide ways in the slide bar, and are also received in oppositely grooved guide rails i fixedly supported on the top plate of the machine, so-that the carriage may travel from side to side of the machine over the top plate.

Upwardly and rearwardly striking type bars 7 are segmentally arranged and the platen. These type bars are connected .to sub-levers 8 by intermediate actuating links 9. Each sub-lever 8 is pivoted at 10 to a keylever 11 which is fulcrumed'at its upper rear edge portion against a fulcrum plate 12 and extends forwardly to the keyboard of the machine where it provided with a finger key 13.'

A universal bar 14 extends beneath the series of key levers and is carried by a frame 15 formed with a rock shaft 16 which is pivoted in the base of the machine. A

this frame and is connected to an upwardly extendmg lmk 18 which m turn is connected t -o a forwardly pro ecting arm 19 of The frame of the machine comprises a adapted to strike against the front face of rear'wardly projecting arm 17.eXte-n ds from a dog rocker 20. This dog rocker is pivoted at 21 to a bracket 22 secured to the-top pl atc of the machine.- The upwardly extending views of certain of. the tabulator stops, the

be embodied in various styles of typewrit-- bar't of the carriage is supported by antiarm of the dog rocker carries teed dogs 23 which coilperate with an escapemcnt wheel V end of the escapeinent wheel shalt carries a feed pinion 26 with winch a feed rack 27 meshes. The feed rack is supported by arms 28 pivoted at 29 to the carriage. Returning springs 30 are connected with the key levers and the parts connected therewith to return them to normal position after the keys have been depressed, and a returning spring 31 is eii'ective to return the dog rocker and associated parts to normal position.

Curved bracket arms 32 are supported on. the top plate of the machine and constitute supports for the fixed guide rails 4. Rearwardly projecting bracket arms 33 extend-from the carriage in line with the openings in the curved bracket arms and con stitute supports for a colunnrstop bar 34-. This stop bar has teeth projecting from the front and rear sides thereof for the reception of bifurcated flatsheet metal column steps 36 in the interdental spaces between the teeth 35. The column stops are thus held against lateral play or movement on the column stop bar and in the dihterent positions to which they may be adjusted along the bar. A tabulator frame 37 is fixedly connected to the frame of the machine in the usual manner by screws 37 and supports a.

pivot rod on which donominational stop carrying levers 39 are pivoted, said levers extending forwardly at the upper ends thereof to form denominational stops l0. These denominational stop levers and the stops carried thereby are maintained spaced apart by devices ll which in the present instance constitute latching means or devices, as will hereinafter more clearly appear. The lower end 42 of each denominational stop lever co-acts with a slide bar 3 which extends, and guided for movement, fore and aft of the machine. Each slide bar, at its forward end, meets with a depending crank arm Mr. fixed to a rock shaft 45 sup ported in upwardly extending bracket arms 46. Each rock shaft 43 has a forwardly extending arm l7 fixed thereto. the arm carrying a denominational kev 48 at its forward end. It will be understood. therct'ore. that a depression of a denominatiomil kev is effective to move the associated bar rearwardlv, thercb transmitting a pivotal movecolumn stops 31' The usual returning springs l9 cooperate v t3: the (ltllflllilllib' tional stop h -"rs to return the r: and the m). 1*. universal her 0 extends across -frame 37. One of the arms 51 is extended Loeeeea the series of denominational stop levers 39 V at the rear thereof and below the pivot v3S. T his universal bar is supported on arms 5i which are pivoted at 5:2 to the tabulator forwardly Where pivotal connection is made at with an up *ardly extending link 541 The upper end of this link '54:. is connected to a lever pivoted {it-5h to a depending bracket 57 which extends from the top plate 3 of the machine. One end of the lever is bent upwardly to form a stop 58 which co operates with the top plate of the machine to limit the movement of the parts in one; direction. The opposite end oi. the lever 55 is pivoted. at 59 to an upwardly extending carriage releasing device (30 guided in its vertical movement by the escapement wheel shaft 61. Contact shoes (32 project forwardly from the releasing device and extend so that an eleva- S5 beneath the feed rack tion of the releasing device (30 from the position shown in Fig. 2 is effective to elevate the feed rack and disengage it from the feed pinion. It will be understood, therefore,- 0 that a release of the carriage is effected at ach actuation of a denominational stop as the latter is projected into'the path of the column stop, and that at' such time the can riage is-free to be moved from right to left 9 under the power of its spring drum (33 which is connected to the carriage in the usual manner. v r

The construction thus far described is similar to that embodied in the ivlonarch machine except that the spacing devices: ll. usually employed in the Monarch machine are of a ditlerent character from those shown in the accompanying drawings. the. usual spacing devices not being in the nature of latching means or device-=. In the present instance 1 substitute for the oidinar spacing means employed between the denominational stop lovers :1 series of latching devices ll which conform substantially in outline to the upper portions of the denominational stop lovers. the latches l] terminating at their lower ends at it. These ltllt'llQH alternate with the denominational stops and are pivoted on the pivot rod 38 for movement fore and aft of the machine in the same general direction as the dcnominaiional stops. As will be seen more clearly from an inspection of Fig. -1, each of the donominaticnal stops 0 has a laterally extending pin or proje tion ('35 extending*lroui the back face theinol l refer to the back face of each donominational stop to distinguish it from the front face ('16 oi the stop with which the column stops ')-Htl ata hu ward- 125 talndat ngoperation citcctodduring the fl travel of the earring? from right lo-ictt-i'n in the direction of its feed. l hn'h pin or oje tion (33 is received in a slot or opening UT in the adjacent left-hand latch 41. This 130 opening or slot is of a' sutiicientextcnt to aiford'a limited independent movement neof Fig. 1, each latch 41 has fixedly con-' vnected thereto, and projecting from its lower -edge,-a depending wire spring68, the lower tween the latch, 41 and its associated dehereinafter more clearly appear.

As will be understood from an inspection nominational stop, for purposes which will end of which is bent to engage around the rear edge ofthe associated denominational stop lever 39. The power of each spring 68 7 1S exerted to force the associatedlatch for-' wardly until it is arrested by the rear Wall of the slot 67 therein engaging the pin or projection on the associated denominational stop, as shown in Figs, 1 and 3.

Each spring 68 therefore tends to normally nainta'l'n this relation between a latch and its associated denominational stop. .It will.

- be seen that-each latch is locatedon the back or left-hand side. of the associated denomi-.

sto-psetO and series of latches 41 are arranged adj acentone another and occupy a space he'-- tween a contact edge 69 and a contact edge 70 of a front plate 71 fixed to the tabulator frame. The-contactedges69 and 7 0 resist a n 1ovemei1t of the .stops and latches inop p'osite' directions. An adjusting screw .72" is received in a tapped opening in the left;

hand side of thejtabula'tor frame 37 and bears at its inner end against theleft-hand "latch 41, as shown in Fig. 4. This screw is 'efi'ective to take 111a any undue v play or lateral motion between the series of denominational stops and the-series of latches t1, although these parts are rather loosely disposed in the frame to provide suflicien't freedom of fore and aft movement between the parts.

- Ina forward tabulating movement 'the l parts co-actin the usual manner andthe denominational stops, through their front contact-faces 66, co-act with the front faces 36? of the column stops 36 to arrest the carriage. As will be understood from an 'inf7 in spection, of Figs. 7 and 8, a movement-of a denominational stopinto operative position is eifectlve to'release the carriage by disengaging the feed raclt 27 from the feed pini n 26.- At the time that'the carriageis ari ted in its forward movement by the co- 0]')1'z-."l0l1- of a column stop with the pro jected uencminational stop 40; the partsappear as represented in Fig. 8. On a com 'parison of this figure with Fig. 7, which shows the positions of the parts after'the denominational stop has been withdrawn from its projected position shown in Fig.

-8, ittwill he seen that the movement of the feed rack back into mesh with the feed pinion from the Fig.8 to the F ig. 7 positioni will afi'orda drop -of the carriage for a distance corresponding substantiallyto the has no particular effe'cton' the operation'of the tabulator in theor'dinary tabulatini-oo eration in' which the carriage moves rom right to left to the point'of arrest except that it' enables the-stops to clear one an other, as will be understood from an inspecvtion of Figs. 7 and 10. It will be seen from a consideration of these figures that if the actuated after-a drop has been effected and the parts are positioned as shown, then the projected denominational stop is in aposition-to co'-act' with the next succeeding column stop, as it is-intended it should.f This clearing of the stops, therefore, is

efi'eetedby the drop scribed above.

In the operationof the devices. for reverse vor backward tabulation, denominational key is depressed, thereby projectingthecorresponding denominational stop forward with its rear face presented for cooperation with the rear face .of the first'co'lumn stop of the carriage deto the left." The operator then moves the carriagetothe right with one hand,lwhilemaintaining the denominational key de pressed with the other, until the'carriage 'is arrested by the cotiperatio-n of the. rear face ofthe first columnstop with the rear face ofthe projected denominational stop. 7 During thismovement of the parts the beveled:

face/T3 of the column stop co-acts with the 1 beveled face'74 of'the projectedlatch 41 ,as shown in Fig. 5, and forces the latch rearon the projected latch, the spring-68 of said latch is effective to move it forwardly on a-rdly around its pivot against the forceof'. I i I the spring 68 of the latch. As soon" as-the column sto'p'has cleared the beveled face 74: r I l the"left-hand "side or back of the column stop, as shown-in Fig? 6. This locks the "column stop and-projected denominational stop together, preventing a movement'of the carriage in the direction of its feed, it being uniderst-oo-d 'that the feed rack is maintained released at this time by. the depression of b the denominational key. The carriage being held at this time, as shown in F igl 6, by the engagement of the latch 41 with the column. stop, said latch will restrain the carriage against movement in the direction of its feed, and Willi-stain it'in the same letter space position that 'the carriage Would-be arrested in by the coiiperat-ion of the same denominational stop with the. same column stop in a. final arrest of the carriage by ,a forward tabulation, through the lmovement' of the carriage from right to left ThlS is thickness 'of one of the denominational or f column stops. This drop of the carriage 80" I same denominational stop 1s,1mmed1ate1y "due to the fact that in the tortvard tabulationthe carriage receives a drop from u in Fig.

in Fig; 9-unti'1 pressure is released on the denominational key. .lVhen pressure is. 'releasedon thekey theydenominational stop" and its latch will 'ino've back to normal 100; I

is to restrain thecarriage against movement .in the direction .ot' its' feed until such. time as a reenga-gemenbof theirack -With'it'sfeed efi'ected" yhentherec'an be opinion has been no such drop of the carriage asis pro:

vided during the reen'gagement of the rack andxpinion during the forward tabulation.

Fig. 7 shouts the parts asthey appear 7 after the-arrest of the carriage-during a .out depart forwardtabulation ,'whereas Fig. '10 shows the parts as they appear after an arrest of the carriage effected by a'backward tabula 7 tion. It Will'be'seenthat in each case the denominational stop 40 and the column stop. 36 bear the same relationso that in" each instance the'carriagc is arrested at the same letter space position assuming of course that the same denominational stopis .employed to co-actwvith the same column stop. Inone case the frontfaces of the'denomination-aldand column'stops co-act to arrest the carriage, although the final position of the carriage atthis time is not attained until the denominational stop is Withdrawn and the drop of the carriagehas been effected. In the other case the rear faces of the .denomi-natio-nal colmnnstops co-act to -arrest the carriage and there is no such drop of the carriage rem this position of arrest; U.

lfhile I have described the use of the latching device in a construction intendedprimarily to attord backward as well as for ward'tabulating operations} itshoul'd be un-.; derstood that th'e'latching device 1s ,ell"ect1ve wherever it is desirable 'to prevent a separai 'i tion of twocooperating contactingtabulator stops through. aLmo-vemeht' oi' the carriage.
