Twalffulwn it 'nt/,ty concern.' 4nBeit-lmcwvn that I, OscAn WooDWAnn, a citizen-Ot the U 'ted States, and a resident of tlieborough of lt anhatian, city of New York,

rOrk, have invented certain new and useful Impr'oycm'ents in, Type-Viriting Machines, of y which .the tollowing is a specication.`

l vThis invention relates to tabulating mech- ;o anisrns -of writing machines and more particularly to `that class Oftabulating mechanisms'in whid-h a series of denomination keys 4,are employed, each of said keys controlling a denomination stop, said denomination stop riagejbeing automatical y released vby -said ley and-.permitted to run freely under the. tension of the usual carriage spring until ar- ,rested by said projected stop at a point Where 2Q thewrtin of a number having the denomination of tlie operated key may bebegun.-

s jf lhe main object of my invention is to pro- I i' vide'anovel construction of the carriage releasing mechanism in .connection with a tabz 5 ulat'or of the class described.

j the accompan 'ng drawings, Figure 1 lis a vlan view` luso much of. a type-writmac e asis necessary to a correct understandng of my invention, some of the ii partslbeingbrpken away and other parts bemg shown in' scction Fig. 2 is a side e1evation of the machine, s 'ome arts being shown ,insecton-andother parts fing omitted and -brkelihityr p -35 In the drawings, theframe of the machine 't-,comprises a base 1,-coiner pplsts` 2 ggd a top.; cruin at 5 in 4plate 3. Ke levers 4are vthe reary of t e base, each ofsaid lileyf-levers lbeing provided with a restoring springt and being connected jby a link 7..W1th a type'bar rollers' ,`18"ai`1dl14, which run upon parallel" guider-aile and 1G. A carriage rack 17 is .o/ ,secured to curved supporting arms. 18 pivoted at 19 at the rear of the carriage V12, and

qs'aid carriage rack normally meshes with a feed .pinion 20, which latter is operatively in the county of New York and State of New ybeing projected by its ke f andthe paper car'- "at its ends in a vertically arranged frame or "bracket 43, said bracket being-clamped to connected to an escapement wheel 21lcontrolled by a feed dg 22 and a holding dog 23, both of said dogsbein'g carried upon theupper end of .a dog rocker 24 pivoted at 25 to a fixed part of the machine. The dog rocker has secured to it forwardly extending arms. 2connected by hooked-members27 with a. 6o universal bar 28 which extends from side to K side of the machine beneath the series of key levers; but only one .arm 26 'and one hooked member 27 appear in the drawings.. l.Vl/'hen the key levers are actuated to cause the ltype oars to print, the universalbar 28 through the connections described vibrates the4 dog .rocker 24, causing the escapement members or dogs 22 yand 23`t co-operate inv a known manner with the escapement wheel 21 to per- 7o mit the platen carriageto be drawn leftward a letter space distance under the inuence of a spring drum 29 with 'which said carriage is connected by a strap or band 30 which en'- gages a hook lsecured to the carriage. The 7S structure thus far described isessentially the samees that of the Well known No. 6 Rem-y in ton typewriter and it is therefore not consi cred' necessary to describe the parts in greater detail. i

One or more column stops 32 are dis Osed along a column-stoprack-bar 33 which' ex-j -tends parallel'with the platen 11 and is suite. A ably secured upon the ends of arms 34; ,rojecting rearwardly from a'bar 35, the latter $5 having downwardly extending ears 36 whichy i are suitably secured to the axlesl'of the rear rollers 14 of thel platen carriage.- I )zenomina vtvoustops 37v are arranged at letterY space intervals apart andsufiicently'in' the rear of 9 `"the column-stop rack-bar '33 to normally clear the column stops 32,'said' denomination stops 37' being formed at'the upper ends -of vertically disposed levers 38fgpivoted on a ffulcrum rod 39 and connected at their lower ends with horizontallydisposed push rods- 40, the latter extending .-.iorw'ardly beneathv the base 1 and carrying at their'ffro'nt-ends keys 42. The ulcrum .rod 39de supported the base of the machine by -set screws 44' (one only of the latter being shown) and be connected near its upper end by a screw 45 with a U-shaped supporting membelffi, `xo5 which member is in turn supported,attire xo ing mechanism as thus far described is generally similar to the well-known Gerin tabulator, and for the purposes of my invention it is not deemed necessary to here describe the parts in greater detaill Above the fulcrum rod 39 the supporting frame or bracket 43 is formed with a forwardly and upwardly prf'g'ecting portieri 5l which is provided with vertical kerfs or slots 52. Each slot'52 receives a bell crank lever 2o 53 fulcrumed on a fulcrum rod 54 which exl tends from side to side of the part 51,. The number of bell crank levers 53 corresponds to the number of denomination stops, which number is ten in the particular tabulator illustrated herein; but the number of denomination stops Aemployed is immaterial. The upwardly extending arm of each of the ten bell cranksj53 is formed with a slot 55. l Engaging-said slot is a'pin 56 secured to 3o and extending laterally from a short ear 57 integral with the associate denomination stop lever The forwardly extending and horizontally .disposed arms of the bell-V l crank levers 53 are off-set laterally as ap- 3 5 pears in Fig. l,- ive of said bell crank arms or half the entirenumber being bent or offset to the left of the escapement Wheel 21 and the remaining half being bent to the right of said wheel. The forward end of 4o eachl horizontally disposed bell crank arm is bifurcated as indicated at 58, the bifurcated portion engaging with a pin 59 projecting laterally from the rear end of a littinfr lever 60. There are ten of these lifting llevers, lone for each bell crank, and they are divided into two groups, one group comprising five of the levers being arranged at the left of the escapernent whee 2l and` its bearing andthe other ve levers being arranged at the right 5o thereof. Beginning at thc rear end the levers of each group irst 'bend laterally outward, these lateral bends 60 being succeeded by portions 60b extending straight toward the front of the machine, the portions 60b being followed in turn by portions 60 which bend inwardl toward the center of the machine. The orw'ard end of each lever 6() is formed with a horizontally arranged lip or lifting shoe 6,1 which normally stands be- 6o neath and out of contact with the carriage rack 17.v `As appears in Fig. l, the two groups lof lifting shoes 61 are arranged so that the 'members composing each group are close togetheL-gthe innermost-member of 65 each group beingbut a short distance from the feed pinion 20. Bearingiy brackets 62 and 63 are similarly secured by headed screws 64 to the top plate ot the machine, each bearing bracket being slotl ted or kerl'ed to receive the portion oi a ill the lifting 7o levers 6l) save thexinnermost lever ofa each group. .The levers 60 move jeely in their slots in the bearing brackets ari d are pivoted on short fulcrum rods 65. T hl e inner endof each iulcrum rod 65 is prol 'ided with a 7 5 fixed collar 66 abutting the in ner lifting lever'60 of the group, said inn r lever being arranged between the collar li and the .end of the bearing bracket. The? outer end of each'rod 65 is threaded to rec eive a iiut 67 8o which assists in retaining the n :id in place.

When it is desired to operatir the tsfbulat ing mechanism the proper den" n'inati l nkey 42 is pushedin, thereby, actua ting tl' ciate lever 38, the lever arm of said lc ver be.- 85 ing swung rearwardly about the uli ruin 39 and the upper arm of said lever bein swung forwardly about said fulcrum; the 1 `sociate denomination stop 37 being thereb moved forward to 'operative position.. i, As 1he upper 9o arm of the lever 38 moves forward ij'actuates the associate bell crank lever 53 tlfuough the pin and Vslot connection 55-56, swinging the orizontally disposed armo the 'bell crank lever downwardly about the ful'crllm 54, said 95 horizontally dis osed arm in tur ,'n acting on' the associate lifting lever 60 tos'ringt-he re'ar arm of said lever downward aloout'th f11l` ,crum 65and the forward arm .lofrsaidlever upward aboutsaid fulcrum.4 Ijs the `foi-wand 1o arm of thelifting lever is swung upward the lip or shoe'61 at its end contacts with' thev carriage rack 17 and swings [the latter upward about the pivots 19.unt `il said rack .dle-

"engages from the pinion 20. i .As soon as the xo' rack is se arated .from the pinion, the caff-- riage 12, ed' or released 'from the escapement devices, is drawn leftward across the' top plateby the spring drum 29, thisrffee movement of the carriago continuing until n the column stop 32 coacts the projected' denomination stop 37. The ke '42-is thereupon released an the paltsof' e'tsbulaltin mechanism actuated b said'key'am rest ore to non'nal position by t esp 49,'-while the rack 17 is caused to re-en gage with the pinion by the usual rack sprin'gmotshowii). .TheA desired characters may then 'lie 'printed in a known manner and theigeafter fthe tabu sting mechanism may be again 4operated the 12 mannerdescribedto release or free tlle car 'riage from its esca ment devices and said carriage to A drawn freely lo until the next colline- 1 stop coacts with projected denomination sto ""ifka It will be observerlthat by myl constnrction I provid aseries of denominationjkeys, each of said eys beingadaptedto oprata'an associatedenomination sto nember? and also to operate an associate evice forreleasx3 'ing the carriage v0i the machine from the es.- capernent devices; that each of said rele'as ing -devices. ,is separate from all the other releasing devices and is operated by the de- I'iomination key with which it is associatedindependently. of all the other releasingr devices.

v `While I have 'shown my invention as cnibodied the tabulating mechanism comr'monly known as the Gorm tabulator and as applied to the No. 6 Remington typevmiting machinej-it is to be understood that said in vention may be adapted to other styles of tabulating mechanisms and writing machines, andthat'various changes in-the construction and in the arrangement of the parts may -effected' without departing from the fspi'rit oft'he invention.
