App lication'filed September 18, 1907. Seria1 No. 393,439.

To ell whom may/fiicern:

. Be'- it knownthat I, ANDREW. W. ,s v a Cltlzell of fihe United States, and resident of Bridgeport, in thecounty of Fail-field and State qiGonnccticut, have invented certain newfind useful Improvements in Type- \Vriting Machines, of which the following is if specification. T

My invention relates especially to the tabnlating mechanism of typcwriting machines and has for its object to provide improved mechanism of the class specified.

To the above and other ends, the invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

My invention is shown as applied to a Remington typewriter, but it is to be understood. that the nature of the invention-is such that it may be adapted to other styles of writing machines.

pile form of the inventiox; is shown in the accompanying-drawings, wl erein- ISO . Figure l is a vertical, front-to-rear, sectional view taken about centrally of a Remington typewriter and showing myinventtion applied theretofparts of the machine 'bein omitted and )arts broken awa Fi 2 is a rear elevation of the machine, parts being omitted and parts being broken away. Fig. 3 is a. l'ragnn-ntary horizontal sectional view taken on a plane between the top plate and the base. Fig. -.l is a front vertical sectional view showing the tabulator key levers and some of the associated parts.

in the drawings. the main Frame of the machine is shown as comprising a base 1, corner posts 2 amt a top plate 3. set ot type bars are circularly arranged on the top plate, each type bar t being connected by a link 5 with a key lever (3 pivoted at the rear of the base. 'lhetype bars when actuated cooperate with the under surface of a platen 7 mounted in a platen carriage comprising aplaten frame 8 pivotally supported on a truck S). The truck is provided with rollers H) which run ona fixed-guide rod It and with a slide which cooperates with a rear lixed guide rod-ll. roller [2 atth e 'lront. ol' the platen l'rame (@lltlltl't'fi wlth a front, shil't rod l3 winch lsTsupported m the usual way on pivoted arms i-t. A carriage feed rack is secured toarms l6 pivoted at 17 to the carnage truck. Said rack is normally spring pressed into engagement as usual with a' feed pinion 1S- the-latter being op-. eratively connected with a toothed escapement wheel 19 cooperative with which are escapement dogs 20 arr: nged at the top of a pivoted dog carrier or rocker 21. The dog rocker is connected with a universal bar by a train of mechanism comprising a link 252, a bell crank lever 23, a second link 24, a crank arm of a rock shaft 25 having arms 26 from which depend arms 26 which are connected directly with the universal.

bar 27 which underlies the set of key levers 6. The parts above briefly described are not of my invention and are found in the Remington machine and need not be more. fully described at this place. we

Referring more particularly tothe tabulat-ing mechanism, this comprises a stop rack-bar 28 supported on angular arms 29 suitably secured to the carriage truck 9. One or more carriage or column stops 30 are detm-hably secured to the rack bar and cooperative with these stops are aset of denominational stops 31 which, as herein shown, project forward from and are integral with the upper ends of a set of upright tIenominational levers 32 arranged slde by side and having open mouth bearings by which they pivotally engage between their ends a fulcrum rod 33 mounted in a hooded frame or supporting bracket, said frame being suitably secured at the rear of the machine. The levers 32 extend straightdown from their pivots through an opening in the base of the machine. The forward edge of each lever 32 is curved at 3:2 substantially concentric with the pivot 33 and a detach able pin 33 extends across the frame 3% near thc curvedportions of the levers so as to a tl'ord a turning of the levers on their pivot pin or rod' but to 'n-event an accidental displacement of the levers from said pivot'pin.

'The frame Ill is-detachable but the mode of attaching it is the lIIYtI'ltlUlLOf another and need not be described in detail.

While 1 have shown the dehominational stops 3! as integral with the levers 32, it is to be male! stood that they maybe separate parts suitably connected if so desired. The Y, denommational levers and stops are suitably guided 'and are adapted .to be actuated by novel mechanism l)l' t'stlltl y to be (It scribed.

.lYhen so actuated they cooperate with a cross bar 35 supported on arms 36 plvoted at 37 to the frame 34. One of the arms 36 has a forwardly extending horizontal arm 38 which carries an adjustable abutment 39 cooperative with a release lever 40. 'Said release lever is pivoted at 41 to a bracket 42 15. When the bar is pushedforward by one of the denominational levers the abutment 39 will press down the rear arm of the lever 40, elevating the lifting shoe a3 and causing it to swing the rack 15 upward out of mesh with the pinion 18, thereby releasing the carriage from its escapement mechanism and permitting it to be drawn freely leftward across the top plate'under the influence of the usual spring drum -14 with which the carriage is connected by a band or strap The tabulating mechanism as thus far described is not per se ofmy invention and it is not thought a more detailed description is necessary.

Referring now to the novel actuating nlechanisn'i for the tabulating mechanism, this mechanism comprises for each denominational stop lever 32 a member, bar or floating key lever or one having a fulcrum or fulcrmn point, the position whereof varies.

during the operation of the key lever, said key lever, member or bar being designated as a whole by the numeral 4.6 and comprising a forward horizontally disposed portion provided with a key 47, a vertically disposed portion extending downward and slightly rearward from the forward horizontal portion and connecting at its lower end with a rearwardly extending horizontally disposed portion 46 which is pressed laterally outward as indicated at. all)" to provide a longitudinally extending strengthening rib. The rear end portion of the part 4(3' is folded over to form a hole, the interior of which is threaded and receives the forward threaded- ;portion of a 'rod 48, said rod being adjustablyconnected with the lever 4.6 and being held in fixed relation therewith by a check nut 4!). The rear end portion of the rod 48 is flattened as indicated at 48 and carries a laterally extending pin 50 which enters a hole in the lower arm of the associate lever 32 near its end. A spring clip 51 is' secured to the rod 48 and cooperates with the frceend of the pin 50 to prevent accidental separation of the dctiuehablc connection between the lever 32 and the rod 48. As will be best seen in Fig. 2, the upper arms of the levers 32 are arranged a letter space distance apart but the lower arms are curved or spread laterally at varying degrees as indicated arms of the levers 32 are spaced sufficiently at 232" so that the lowerfar apart to permit the connections of the rods 48 and levers 40 to be arranged side by side without causing interference between said rods, levers and connections. The curved portions 32" of the lovers 32 are or may be strengthened by curvedstrips 32 of metal suitably secured to said levers.

Each lever 46 is pivoted on an arm or guide link 52, said arm being formed preferably of sheet metal and having vertical side portions 52 which at the rear incline toward each other so as to lie close to or embrace the associate lever 46 at its vertically disposed part, said arm and said lever being pivotally connected as by a rivet or pin, 53 passing from one portion 52 to the other through the lever 46. The arms 52 are inclined to the horizontal and, in thepresent instance, extend downwardly and forwardly from the pivot pins 53 toward the front. of the machine, The side portions 52 of each of said arms incline laterally away from each other from rear to front and are perforated at their forward end portions to receive' a pivot rod 54. Said pivot rod is secured at its ends by screws 55 in angular bracket 50, the horizontal portions of said brackets being provided with slots 57 which receive securing screws 58, said securing screws entering the base frame and thereby detachably and adjuslably securing the brackets 50 and the pivot rod 54 in a lixcd relation with the machine. frame. The construction is such that when the key ll is operated it moves nearly straight downward, whereas"the rear end of the bar It; moves toward the rear of the machine. The forward and rear ends of the bar l t; move in paths that are nearly at right angles to each other. The construction is such that the spreading or (ll\'( lure of the side portions 52 of the arms 013 provides a broad and stable bearing for each arm on the pivot rod 5i and at the same time tends to maintain the arms 5; properly spaced apart. shown in Fig. 3 the leversdti fan or diverge from rear to front. The forward horizontal portions of said levers pass through guide slots in a combined guide and cover plate 51) which is secured by screws (it) to the brackets 56, the upper portion of said plate being rcarwardly inclined and formed with a'slot til through which the usual or a suitable tabulator scalc (,2 may be inspected, said scale being suitably attached to the guide and cover plate 5%). The detail constriwtiou' of the scale is not my invention and need not. be described. liy loosening the screws 58 the guide plate may be adjusted laterally of the levers 46.

The lower part of the vertically disposed portion of each lever 40 is guided in the slot formed in a guide or comb plate (33, said coi'nb plate being secured at. its ends to angular brackets (34 fastened by screws (35 to Itlo III)

the guide, plate 59 and the comb plate 63 adjustable, the accurate assemblage and. ad-

' 46. Eachlever 46 is provided with'a helical the other end to the guide or comb plate 63. v The spring-tends to maintain the lever 46 in i understood that the lever 46 and the rod 48 in: one direction, means beingiprmgided to 'againstthe closed-end of. the slot 58 in the crum 534 and the pivot 5'3 b eing'above the ,per arm of said lever 32 forward, projectthe inner sides of the base. Each bracket is formed with a slot for the free passage of a headedsc-rew '66, said screw passing through the slot in the bracket and entering a threaded hole in thecomb plate 63. By making justment of the levers 46 in the machine is facilitated. The bracket is engaged beneath by the comb plate and above'by thehea-ds of plate may be adjusted laterally of the levers restoring spring, said spring being secured at one end to the horizontal arm 46 and at the position-shown inltig, 1, the forward horizontal portion of said lever abutting plate 59. Each of the levers 46 is provided with a projection or abutment 46 which is" adapted when the lever is operated to contact with the top of the comb plate 63and limitthe depression of said lever. It will be constitute in effect a single member, said member or lever being pivotally connected directly to the denominational lever 32. and also to the associate arm 52 and being provided with means (i. e. thescrew connection between the lever 46 and rod 48) "for varying its length. V

When any finger key 47 is depressed to operate its lever 46, the associate arm fag-will. be turned downward about its pivot/6r fulhorizoutal will move in aitf'arc or path which will curve downward and rearward. Be.-

-ause of this movement of,the pivot 53- the lever 46 as 'a whole will move rearward, while its forward end is receiving a downward movement, forcingthe lower arm of the associate lever 32 rearward and the uping the associate stop'i-ll into thepath of the carriage or column stop or stops and ell'ccting the release of the carriage. 'lhe/ downward IIIOYOIHtBllt'Of the lever 46 will be finally arrest edby the contact of the stop 46 with the comli plate 63. lVhen the demessed' -l cy lever 46 is released the associatespring 67 will restore the lever 46 and arm 52 to ,the positions shown in Fig. l.

it will be seen that by my invention 1 provide simple and ctlicacious actuating de- Vices for the tabnlating n-iechanism'; that said devices comprise tabulatingkey bars or levcrs each of which is movable atjoneend cause the lever to move in another direction substantially at. right angles'tq the first direction when the end of the lever is so moved; that. said means in its preferred form includesa pivoted arm 52; that the actuat- I ing devices comprise few parts and are controlled by a set of depressible keys which are'arranged above and slightly to the rear of the regular keyboard of the machine so that they will not interfere with the operation of the regular keys; and that the floating tabulating key levers extend from their keysat points above the printing key levers' downward between the printing key levers and to points beneath the samewhei'' theyare connected with the denominational levers which extend downward between the printi11 key levers to points beneath the same.

34y invention has been embodied in a complete machine in which the parts and elements above stated to have been invented by others, and more especially the tabulator 'supporting'frame and the tabulator scale devices, are shown, and I have preferred to 46 at the pivotal point the edge 46 'may be caused to cooperate with the closedend of the a'ssocialtqe slotin the comb plate 63, acting a cal when the associate key '47 is depressed/to force said bar 46rearwa'ird as a I \vhole/ The operation when the arm a2 is.

connected with the bar or lever 46 is, however, easier and smoother.

Various changes besides those noted may be made in my invention without departing from the scope thereof.
