CARL GABRIELSON, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR TO UNION TYPEWRITER COMPANY, OF JERSEY CITY, .NEW JERSEY, A CORPORATION OF NEWJERSEY.

TYPE-WRITING MACHINE.

To all whom 'it may concern.'

Be it kn`own that I, CARL GARiELsoN, a citizen of the United States, and a resident of Springfield, in the county of Hampden and State of iifassachusetts, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification. v

My invention relates to denominational tabulating mechanism for typewriting machines, and the main object of said invention is to provide a simple and et'iicient mechanism of the character described.

A further object ot' the invention is to provide simple and ei cient automatically operated means for preventing rebound of the carriage when its travel is arrested by the engagement of the tabulator stops.

Tothese main ends my invention consists in the novel features of construction, arrangements and combinations oi parts to be hereinafterdescribed and more particularly pointed out in the appended claims.

Fig. 20 is a perspective tending bell crank lever 10 which is pivoted-at 11 to a key lever 12 that is pivoted in the frame of the machine at 13 and is provided with the Vusual finger key 14. I

This bell crank or vsub-lever 10 has a dependingpertion which extends below its associated /keyvi'ever and l which is slotted at l5 forco-operatiptiwith a fixedfulcrum bar 16 that may be supported by suitable brack-v ets 17 and each of the key levers may be'restored tothe normal position by a spring 18, all as fullyshown and described in the, Letters PatentNo. 657,927,l granted to Jacob Felbel, September 18, 1900'. Extending be neath the various key levers 12 is a transverse universal bar 19 which is' connected at its'ends to upright links or rods 20 which in turn connected at their upper ends to a rocker arm 2]. that projects fronia,y rock shaft 22, supported by centers or pivots 23 and provided 'l with a carrier 24 for the usual feed dogs'25f' 26 is the usual returning spring for thedog rocker. The feed dogs 25 co-operate vwitha feed or eseapement wheel 27 which is operatively'connected :to a shaftv 2S,

(see Fig. 21) that rotates in a bearing 29 and which is` provided at'its forward end witha feed pinion 30; 'Co' operating with this feed pinion. 30 is a carriage 'feed rack 31 that is carried by arms 32 which are'securcd to rock shafts 33 adapted to rotate in bearings 34. on the carriage 35. These rock shafts 33 may each be provided with a finger key or crank arm4- 36', bygmeans of which the 'rack 3'1 may be elevated or disengaged ironitlie feed pinion 30 and thus permit a free movement of tlief carriage. 'lhis carriage 35 includesv a bar 37 having" oppositely disposed track or race-ways 38. Antifric tion balls 39 are adapted to be received f withi'n these race-ways andin the cooperating race-'waysof the fixed rails 40, which are secured to brackets or uprights 41, that in turn are mounted to the top'platc 2 oi the machin e.

chine is provided a series of denominational key levers 42 which are pivoted at their rear ends on a rod or pin 43 that is supported by bracket arms 44 depending from the base portion of the frame of the machine. Each of these denominational key levers extends to the keyboard of the machine and is provided with a fingerykey or button 45. Each denominational key llever is likewise provided with a contact piece 46 which is preferably rounded at its lower contact face 47 and these Contact pieces are made in loop or U-form and are so secured to the lever as to leave a space between the bottom of the lever and the loop for the reception of one end of a spring 48, which at this point may also engage a notch in the key lever, as shown in Figs. l2 and 13. The rearwardly projecting free end of each spring is adapted to bear upon a xed cross-bar 49 which is carried by the bracket arms 44.

Upon examination-of Fig. l of the drawings, it willl be observed that the various contact pieces 46 are secured to their respective denominational key levers at varying distances from the pivot rod 43 thereof. These Contact pieces 46 are adapted to bear upon an underlying bar cross-head or horizontal plate 50 which preferably is formed integral with vertically arranged side arms 50, the plate and arms formingA a sort of frame which is pivoted upon a bar l that is secured to bracket arms-"2 which depend from the frame of the machine. TE .e rear ends of thev side bars 59E of the frame are united by a pivot piece 53 from which extends upwardly a rod or link 54 that projects through apertures in the hase plate and top plate of the machine through a tube 55 which is supported on the top of the base plate. This rodor link 54 has an adjustable. collar 56 to serve as an abutmentfor the upper end of an expansion spring 57; the lower end bears upon the flange 55a. formed at the lower end of the tube 55, as

threaded sleeve 71.

shown at Figs. 1 and 2. At Fig.5 the spring is broken away. The upper .end of the rod or link 54 is threaded at 58 and receives the sleeve 59 forming part of a rack frame or carrier 60 having vertically arranged teeth 61. .Iam-nuts 62 may be threaded upon the rod above and below the sleeve 59 of the carrier so as to enable it to be adjusted and held'inithe proper position. This rack carrier 60 is slotted vertically and longitudinally as at 63 for the reception of a headed screw 64, the threaded stem of which takes into a threaded opening in a bracket 65, which is secured by screws 66 to one ol the carriage supporting brackets 4l. Another bracket 67 is secured in position in a like manner and both brackets constitute supports or bearings lor a stop rod or rock shalt 68. Thus upon reference to Fig. 14, it will be seen that one end of the rock shaft or stop rod 68, which is cylindrical in cross section, is received within a cylindrical opening in the bracket so that it may rotate therein. The opposite end of this rock shaft is provided with a reduced portion 69 which forms a circumferential shoulder 70 that -bears against the inner end of an externally The threads vof this sleeve engage internal threads in the bracket 67 so that the sleeve and stop rod may receive a slight longitudinal adjustment. The outer end of the reduced portion of the stop rod has a threaded opening therein which receives the stem of a headed s1. rew 72, and the head of the screw is received within an opening in the knurled head 73 of the sleeve 7l and bears against a shoulder 74 formed by said opening. By these means the rock shaft is free to turn'in the sleeve 7l and the opening in the bracket 65 but is prevented from longitudinal movement, though as before stated a slight longitudinal adjustment may be given to the rock shaft by turning the sleeve 7l in its bearings and a jam-nut 75 may be employed to rigidly secure the sleeve in its adjusted position. The lefthand end of the stop rod, in Fig. 14, is apertured for the reception of astud 76 which projects from one side of a pinion 77 and a pin 78 is passed through openings in the stop rod and stud to secure the pinion and the stop rod together. This pinion 77 meshes with the rack 6l, hereinbefore described, so that a vertical movement ol the rack to different extents will cause a turning of thc stop rod to different extents. The stop rod is serrated at 78x on opposite sides thereof so as to form teeth and kerfs and the bases of these kerfs are straight or flat as indicated at 79 in Figs. 9 and 16. A column or tabulating stop 80 projects from a segmental stop carrier Sl, which is illustrated in detail in Figs. 9 and l0 of the drawings. This stop carrier i's forked or bifurcated as at 82 and adapted to co-operate with the walls 79 of the serrations in the stop rod and thusenable the stop and rod to rotate together. It will be understood that when these forks are seated within the serrations, which are letter space distances apart, the stop and its carrier are prevented from moving longitudinally upon the stop rod, and in order to prevent accidental detachment of the stop carrier from the rod, I have provided a C shaped clamping spring 83, which is secured at its middle by a screw 84 within a C-shaped housing 8l.n forming part of the carrier and extending laterally of the forks 82. Said spring embraces a cylindrical portion of the stop rod below its axis and thus tends to hold the stop carrier upon the rod. In order to adjust thev stop on the rod 68, it is merely necessary to withdraw the stop carrier laterally against the tension of the spring 83, and re-engage it with the rod at tho desired point by insel-lf ing the forks 82vinto opposite kerfs and causing the spring to embrace the rod, as at Fig. 9. number of letter spaces which the carriage may make maybe provided upon the stop rod to facilitate an adjustment of the tabulating or column stops thereon.

The various tabular key levers 42 are limited in their downward movement by stop pins or screws 86 which are held in or threaded in openings in a plat-e 87-that is supported by depending arms 88 from the base of the machine. It will be observed that these various stop pins 8G extend to different heights and thus vz.-

riably limit the depression of the different denominational key levers 42. These key levers 42 are adapted to bear upon a cross-bar 89 which is connected at its ends to a yoke or frame 90 that is pivoted upon the rod 5l, heretofore described. One side ol this yoke or frame 90 is extended rearwardly to form'an arm 91 to which is pivoted at 92 a link or rod 93 which is preferably a two-part link; the separate parts of which are threaded at 94 with right and left-hand screw-threads, that co-operate with a`turn buckle 95 in order to shorten or lengthen the link. The upper end of this link is pivoted at 96 to a horizontal lever 97 that is pivoted at 98 to a stud'99 which projects from the under-face of the topl plate 2 of the machine. To the inner end of this lever-is-pivoted at 100 a feed rack disengaging piece or yoke 101, which is bitureited at its upper end A scale 85 or bar or plate through the contactot' the part 46 therewith but Athat such depression will likewise cause a downward movement of the yoke 90, thus drawing down one end oi the lever 97 and elevating the opposite end thereof, which causes the disengaging yoke or.

piece 101 to be elevated and the carriage feed rack 31 lo be lifted from its pinionSO. The yoke or rack litter |01 is guided during this vertical movement thereof by .its arms 102 engaging within recesses 104 ith-med in the bearing 29 ,oi the feedpinion shaft 28, as illustrated in Fig. 21.' Depression of the various denominational ,key levers will variably depress the cross plate or bar 50 or move it down differentl distances according to' the ,key lever operated by reason of the location or arrangement oi the contact pieces 46 at various distances from the pivot 51 of-the`pivoted cross plate 50, and by reason of Athe fact that the depth of depression of the different denominational keys is controlled or variahly limited by the setting of the cooperating stops 80, of which there is one ior each said key lever. The effect of this varying depression of the cross plate* 50 is to impart to the stop rod (through the link 54, rack-61 and pinion 74) a differential or variable turning movement or oscillation in order ,to`

, bring the 'tabulating stop thereon into the path of the desired denominational stop carried by the carriage. The stop 80, in turning with the stop rod, moves in a plaire that extends fore and ait of the machine so that the impact against the stop is received lengthwise against the rod and does not tendito move the stop from -.the position towhich it has been turned. A bracket 105 is secured by 4screws 106 (Fig. 15) to the carriage rack bar 37 and this bracket is formed or provided with a tubular or hollow cylindrical stop carrier 107 and provided interiorly with a series of radiallyarranged denominational stops l108. These stops are.v also segmentally or` eircularly and spirally arranged, as

indicated in Figs. (i, 7, 8 and 16 of the drawings, and are situated a letter space distance apart in their spiral arrangement or considered longitudinally of the tube 107. Eight of these concentrically arranged stops are shown, there being one for each denominational key employed. This cylindrical stop carrier surrounds the stop rod'and `the tabular stop as shown in Fig. lli and during the movement oi the carriage when the tabulating mechanism is not in operation, the tabular stop on the rod 68 will not arrest the4 carriage, because. it stands normally in a position where it cnnnot be struck b'yoneoi' thedenominational stops 108, llyreferringto Fig. 10, it will be observed that the said stops 10S do not extend completely around the inside of the tube or carrier 107 and hence that there is a bla-nk spacelOSX at the forward portion oi the tube for the accommodation of the stop 80 which normally projects forwardly ns shown in full lines in said ligure.` 1t will `therefore be seen that in the back and forth travel of the carriage when the sleeve passes over tlic stop device on the rod`68 there is nothing for the stop 80 toy be struck by and hence it will fail to arrest the carriage. When, howover, a tabular or denominational key is depressed, it will cause a 4corresponding depression of the rack 61, which will result in the stop rod being turned in its bearings, thus moving the column stop 80 from the full line position shown in Fig. 16 to, We w-ill assume, the dotted line position represented in the same figure, and at which time the tabulating stop extends in the path of one of the denominational stops,vsaid denominational stop depending upon the particular tabular key which as been depressed. It will be seen that at or about the end of the turning of the stop 80 to the selected position, the 'lever 97 is vibrated and the earriage feed rack disengaged from its pinion, and the carriage is free to be propelled in the direction of its feed by the ordinaryspring drum 109 `and sti-'ap 110 secured to said drum at 111 and connected to the carriage at. 112 by hooking upon an arm 113 depending from the carriage in the usual way. A separate denominational key is provided for each denominational position and is 1effective tomove the tabulating .stop y80 into the path of the corresponding denominational stop. Thus, for instance, the tabular key which is shown provided with a decimal point is adapted to turn the stop rod and the tabulating stop 80 thereon into the path of the last of the vseginentally arranged denominational stops and of course to simultaneously release the carriage, whereas the vunits denominational key will turn the stop rod so as to move`the tabulating stop 80 into` the path of the next to the last denominational stop 108, and so on throughout the remaining tabular keys.

On account of the spiral arrangement of the denominational stops, or of their offseting one from the other progressively as they extend round inside of the tube, their operative faces lie in parallel vertical planes, taken transversely through the tube, which are equidistant and at a letter space distance apart, as indicated by the dotted lines a at Fig. 8, and hence these stops 108 are adapted vto caiise the arrest of the carriage at diverent denominational positions, depending upon the amount of'rotation or oscillation given to Vthe stop 80 or to its angular position on the rod at the completion oi its oscillatory movement,V the stop 80 (in any position which it mayoccupy Aor be set longitudinally on the rod) swinging always in the same vertical plane that extends fore Aand ait. ofthe machine but to different extents or to different angular positions. Thus if it be desired to.write 10, the denomiuatiorial key bearing the inscription 10. is actuated and .the column stop 80 is turned rearwardly l1-15 in the direction oi the arrow in Fig. 16 to what may be called its third position, (said stop being adapted y lo be turnedv to eight diiierent'positions) and in this position' it will be brought Ainto the plane or path of movement of the relatively vfixed third rdenomina- 120 tional stop on` the carriage (counting fromv decimal stop) and hence when the carriage is released and said denominational` stop strikes the stop 80, the carriage will be arrested and in the proper denominational position for the immediate writing in of the numeral 1 of the- 125 10 to be written. The denomination key having been released upon the stoppage of the carriage,- the carriage maypf course continue its step-bystep 'feed movement ns the numeral type keys are actuated to enable the operator to typewrite the amount to be written.

In further explanation, let us say that the column stop 80 is set at the point 60 on the scale oi the column stop rod so as to define or determine the righthand side or limit of the column to be written. ii the decimal key be depressed, the carriage will be released and arrested at the sixtieth position oi the carriage or when this part oi' the platen is in register with the printing point. It, however, the units key be depressed, the carriage will be arrested one step or letter space in advance oi said sixtieth position; it the tens key be depressed, the carriage will be ar. rested two spaces in advance oi said position and so on up to the highest denominational key, which in this case is millions, and when thel last mentioned key is actuated the carriage will be arrested seven spaces in advance oi-the point 60 or at 53 on the carriage scale, so that when the amount 1000000 has been written in, the sixtieth point on the right-hand side of the column will then be brought in alinement with the common printingr center. Thus the carriage has a greater length of jump or travel when'the lower denomination keys are actuated than when the higher ones are used, for ii the carriage be at 40" when the units key is actuated the carriage will skip from 40 to 59]y whereas if .the millions key be employed, the carriage will skipfonly from 40 to 53. Hence the denomination stops f 108 are arranged with the units at the lett-hand end of the spiral or the leithand end of the tube, and the millions at the righthand end thereof, the carriage'being arranged in this instance to travel irom right'to left considered from the front ofthe machine.

At Fig. 1.6, I have indicated the values orthe dilierent stops by placing marks corresponding thereto in radial alineinent therewith and from this it will be observed that the stop. 80 is turned one step to arrest the carriage at the decimal position, twice far to arrest the carriage at the units position7 and so on around to its eighth position in order to arrest the carriage at the millions place. In practice the carriage is not released until the stop S0 has been whirled around into the path oi the proper denominational stop, but the release mecha/nismvis started in action just before the completion of the rotation ol' the stop 80.

It will be observcrl-v at Iiigs. (i and S that the active or stopping iat-.estoi the teeth oi the stops IOS are plane but that their backs and sides are beveled or tapering and so as to reduce their thickness or wid th at the points or tree ends, while leaving th em suiiiciently wide and irm bases towithstand the shocks or blows to which they are subjected. ,By tapering or lieveling the backs oi the said stops or teeth a wider space is created between the face of one tooth :and the back of an adjacent tooth at and nearfthe free ends of the teeth and this space is made sulliciently wide t0 enable the tree beveled end of the column stop tooth 80y (which is preferably beveled in an opposite direction to the bcvcling on the stops l08) to swing through between two adjacent teeth and thus avoid or escape any 'oi the teeth lOB when swinging around to the selected position in the event that at the time the tabulating mechanism is to be actuated the tube carrying the denomination stops is over or sur-l rounding the column stop and which latter might be arrested or blocked'bnt for this provision or feature'of` construction.

Now t The plate 50 and its supporting bars may be considered as a universal frame since it is actuated by each dcnomination key lever; and the cross-bar 8l) and its su pporting` arms may likewise be considered as universal trame for the same reason, the first mentioned frame :acting always on the column stop bar to turn it through dilicrent distances and the last mentioned frame acting always on the feed rack to disengage it from its pinion when any denomination key is depressed. .he extent of depression of the

universal frame

50, 50 is regulated or determined by the extent to which the key lever l2 in action may be depressed, the said key-levers having each a different extent ol depression, and this is prodetermined by the setting of the scro\vstops 80; for cxample, the stop 86 which limits thc downward movement ol the denomination key representing units is higher than the stop which controls the descent oi thc key representing thousands and hence when thc iormcr key is actuated it is depressed less than the thousands key und in turn deprcsses the universal frame to u lcss extent and through it and its connections turn thc column stop S0 through a smaller arc than when thc thousands koy is operated. Preferably the series of denomination key levers 42 are guidcd :it near their forward ends 'by a comb l2 rising from the pluto 87. Prolcrably also cach denomination key lever 42 is for-mcd or provided on its undcrsidc with u projection. 42 for operating the universal humo that connects with the curriugc rclcu'sc und thcsc projections or lips l2 muy bc oi diilercut lengths und so as to strike tho cross-bm' Si) oly snid immo ut dill'crent limos in the dcprc ions of the dil'lercut levers and so as to rclc-.isc the (uiiiagc ut the proper time, it boing desirable as bcl`orc cxplniucd, that the carriage bc not released until the column stop has 'been turncd around into thc path oi thc sclcctcd dos nominational stop. lint for thc provision ol' lhcsc diit'erent sized lips or projections y12" thc carriage might lic prematurely rclcuscd during thcy operation of om ol thc keys having the greater dcprt sion.

lpart of my invention is concerned, thc said antiwar nage-rebounding means muy be employed in connection with various other styles or consiruclions oi column stop and tabulating mechanisms. In the coustruction represented in these .ligurcs the slop rod 86, instead oi being fixed against longitudinal movement in both directions, as in the construction hcrcin` before described, has a slight movement in the direction oi its length and this is effected by providing a space between the circumferential abutment 70 litl formed by the reduced bearing portion 69*L on the rod and the inner end of the externally screw-threaded sleeve 71. In this construction the head 72b of'the screw72a is extended outside of and beyondthe knurled head 731 on the sleeve 71, and c'o-operating with this head 72J is a yoke 113 that is carried by the free end of r a lever 114 which is' pivoted at -115 lto a bracket 115 and aspring 116 exerts a pressure on saidlever-in the direction of the arrow in Fig. 18. Pivoted to this lever at 117 intermediate of its ends is a link 118 which has its opposite end pivoted at 119 to an engaging piece or lever 120 which is pivoted at 121 to the bearing 29 o f the -feed pinion shat. i The forward or free end of this engaging piece or lever is adapted to bear against and co-operate with the side of the feed rack 3l and thus check or prevent a rebound of the carriage and assure its maintenance at the position where it is arrested by the tabulating mechanism.

- When a tabular -key is depressed the releasedcarriage is drawn by its spring drum in the direction of l l 1o nominational stops reaches contact with the tablulatl ing stop 8O which has been interposed in its path. The impact of the carriage, or of the denominational stop carried thereby, against the interposed tabulating stop will cause the stop rod to receive a slight longitudinal lnovement toward the left. This movement will be transmitted through the lever 114l to the link 118 and by said link to the arresting piece, brake or dog 120 whose inner end 'will be swung into contact with one side of the feed rack and pressing thereon, thus prevent a rebound of the carriage. As will be seen at Fig. 18, the dog is normally out of contact with the side of the rack 31 and occupies such an angular position in' reference thereto that when its point is swung to' Wards the right by the impact of the carriage, said point approaches and binds orclamps against the outer sidev of the feed rack somewhat after the fashion of a cam or eccentric. When the carriage is moved to the right or the tabulating key releasedlby the operator, the tabulating stop will no longer be under compression of the carriage. spring, by reason of the fact that the tabulating and denominational stops are no longer in contact and the spring 116 is at this time effective to move the stop rod towards the right to the normal position and at the saine time release the holding dog 120 from contact with the carriage feed rack.

It will be observed that the device shown and described fory preventing the rebound of the carriage is automatic in its action and that the greater the force of impact of the carriage against the tabulating stop, the

- greater will be the hindering vice 120 against the side of the feed'rack; It will likewise be understood that theshock of the impact of the carriage against the tabulating stop is not resisted by a fix-ed abutment but'it is distributed and the force of the impact is employed to effect the actuation of the vmechanism for preventing a rebound. of the carriage. l This mechanism is of value in tabulating i devices wherein ordinarily the carriage is liable to rebound one, two, three or even four letter space distances and the feed rack will often engage its pinion before the carriage has an opportunity to recover from the rebound and to settle against the tabulating stop, so that the carriageinstead of being arrested at a predetermined -ment or proper denominational position.

' its feed with considerable speed until one of the deforce of the pressure depoint will be arrested at one, two, three or four letter space distances to the right of sucli point. The operator ordinarily will not perceive this defect until the writing has been done, when, too late, it will be found that the figures ofthe columns arethrown out of aline- By my present invention, these diiiiculties are entirely obviated and a simple and efficient device is provided to prevent a rebound of the carriage. As far. as this part of my invention is concerned, very many different changes may be made in the means for holding the carriage or resisting its rebounding action without departing from the spirit of my invention and it will be understood that the dog or other pressure device -120 which is moved into position by the impact of the co-opera'ting stops' may be otherwise formed and may engage some other part of the carriage than the feed rack, which in the present machine isemployed merely because it is convenientto use it instead of applying a separate and independent bar to the carriage o r using some other part of the carriage in lieu thereof. This mechanism may also be used in tabulating devices Where there arey no denominational stops but only column stops.

While I have shown and described but one embodiment of the various features of my tabulating invention, it should be understood that many detail changes in the construction may be made withoutl departing from the spirit of my invention and that one or more of the features of the invention may be employed with-A out the others.l In companion cases filed .of even date herewith and bearing Serial Nos. 97,493 and 97,495,

some of my improvements are shown carriedout in other forms of tabulating mechanism. l
