TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed September 16, 1914. Serial No. 861,965;

To all whom it may concern:

Be it known that 1, (11.10 of the United States, and residentof Arlington, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

My present invention relates to tabulating mechanism for typewriting machines, and its general object is to provide new and improved mechanism of the character specified.

More specifically, one object of the invention. is to provide novel column selecting mechanism; another object is to provide novel denominational tabulating mechanism and still another object is so to construct said novel mechanisms that they may be em-.

1 bodied in a single typewriting machine.

To the above and other ends, my invention consists in the features of construction, com-.

binations of devices, and arrangements 0 parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings which illustrate the preferred form of my inven-- tion, Figure 1 is a fore and aftvertical sectional view of a typewriting machine embodying myinventiom-only so much of the nominational tabulating mechanism. Fig. 2

B. YAw, citizen and a connecting top plate 2. Fixed to the rear portion of the main frame is a guide rail 3 grooved at its top and bottom to cooperate through anti-friction rolls 1 with a motor or spring drum 8 supported on a frame 9 detachably secured to the end plates 1. The connections between said, motor and said carriage comprise a gear wheel 10 concentric with the spring drum, said gear wheel meshing with a set of teeth 11 on a a second series of teeth 13 that mesh with a feed pinion 14 controlled by escapement de' vi'ces so that while the'constant tendency of the motor 8, acting through the described connections, is to draw the carriage leftward. this movement will be controlled by the printing keys acting through the escapement devices so long as the latter'remain in control of the feed pinion 11. Said feedpinion is loosely mounted on a shaft 15 which, as best appears in Fig. 2,'is journaled up'onthe frame 9. A slidable'clutch member 16 is mounted on the shaft 15 below the pinion 14: and is provided at its upper end with ratchet of clutch teeth which mesh with corresponding clutch teeth on said pinion,

said clutch member being normally retained inoperative engagement by a spring 17 coiled around the shaft 15.. The clutch member'is caused to turn) always when said shaft turns by reason of its engagement withnotches'formed in a flange 18 fixed to said shaft. The construction permits? the clutch member to be slidv down along the shaft 15 to disengage from said pinion without disconnection from said shaft. Fixed to the lower end portion of the shaft 15 is a toothed escapement'wheel 19 with which cooperate escapement dogs 20 and 21 mounted on a rocker or carrier 22, which is fragmentarilv shown in Fig. 1. Said dogs are controlled by printing keys, as disclosed in my pending application Sr. No. 855,551,

filed August 7th, 1914. To move the clutch member downward and release the carriage devices means are provided which cotiperate with a circumferential groove 23 in said clutch member, as hereinafter described.

rack bar 12 which is further provided with Both the column selecting and denominational stop devices that are key controlled.

cooperate with adjustably mounted carriage carried or column stops 24. Any-desired a plurality of combinations or arrangements of carriage stops 24 to beset along the bar and brought separately into use by rotating the bar 25 until the proper setting is obtained. The bar 25 is located so that during carriage movements it carries the column stops 24 between the denominational stops, which are located at the front side of the bar, and the column selecting stop member, which is located at the rear side thereof, so that while the rear face or portion of each carriagestop 24 may cooperate withthe column selector to arrive at a predetermined columnar position, the front side of said stop may cob'perate with the denominational stops to arrest the carriage in desired denominational positions. 7

Both the column selecting and denomination stops are mounted on a detachable frame at the rear of the machine. A cross bar 28 extends from the bottom edge of one end plate 1 to the other and is screwed to said end plates. Rising from said cross bar, to which it is detachably secured by screws 29, is a frame post or member 30, (Figs; 1

,a long and 4-6). The denominational stop levers are mounted to swing back and forth, as hereinafter described, in a series of parallelvertical guide slots 31 in the upper end portion of said member, which is also cut away, as indicated at 32, to provide-a free passageway for the travel of the carriage stops.

The column selecting mechanism will next be described, reference being had especially .to Figs. 4-8. Two parallel supporting arms or brackets 33 are screwed or otherwise secured to the post 30 and extend rightward therefrom, or toward 1 the left when viewed from the rear. As seen in Fig. 6 each bracket fits around a corner of the post, having an angular extension 33 which 7 the stability of the bracket. "Aitits-freeend.

each bracket is curved rearward and is boi 'e'd out to provide a bearing for an upright rod or rock shaft 34, the ends whereof project beyond the bearings Secured to the upper end of said shaft is a bell crank comprising arm 35, a short arm 36, and a hub portion 37, which hub portion'receives a set screw 38 by which the 'bell crank "is secured shaft 41.

'shaft41 is a multiple column stop member,

menses to the shaft. The lower projecting end ofdesignated as a whole by the reference numeral 42, said member comprising a central cylindrical portion 43 fromwhich radially project any desired number of teeth or stops 44. There are eight of thesestops or contact devices 44 in the present instance and the multiple stop is arranged at such a height that when swung forward, as hereinafter described, these contact devices will enter the path of the carriage stops 24. Preferably in the present irTstance the said member further comprises a'downward extension or hub 45 terminating in a ratchetor detent wheel 46, the whole member being suitably secured to the shaft so as to rotate therewith. The multiple stop is arranged above the arm 35. Between said arm and the arm 39 the shaft 41 receives a hub or barrel member 47 which is partly hollow and is fixed to the shaft by one or more set screws. The barrel 47 is provided with a series of radial projections or stops 48, these and is partly housed within the barrel, thev upper. end of said spring being secured to the barrel while the lower end is anchored to the arm 39. The tendency of the spring is to turn the column selector, comprising the barrel and the multiple stop, in the direction of the arrow in Fig. 5 and to maintain a stop pin 50 projecting upward from the barrel in contactwith a downwardly projecting stop pin 51 on the arm 35. The other bell crank arm 36 is provided with a pin 52 over which is hooked one end of a draw spring 53, the opposite end whereof is an chored to a pin 54 on the upper bracket 33. The tendency of this spring is constantly to throw or swingthe frame, comprising the shaft 34, the bell crank 35, 36, and the arm- 39, together with the column selector carried by said swinging frame,toward the rear. The rearward swing, however, is limited by the pin 54 engaging with the. forward end of a slot "55 formed in an angular extension 36. of the arm 36 (Fig. 6). The

, forward swing ofthe frame and the stop devices or selector which it carries is limited by the engagement of the rear end of the slot 55 witha stop pin 56 on the bracket 33 (Fig. 8). .This forward swing is for the purpose of bringing said stop devices into operative position and is caused by horizontal key controlled arms or actuators 5.7 which are arranged loosely one above the other on the. shaft 34, being properly separated by washers 58. There are in the present instance eight of these actuators and their end portions are adapted each to en-' gage with one of the projections 48,- the ac-. tuator thus combining the junctions of an actuating device and a stop. When lled forward each actuator, is adapted to'contact with a vertical rod 59, secured at its ends to the arms 35 and 39 somewhat to the right of the barrel 47, and through said rod 59 communicate movement to the swingin frame and'stop-devices. .The actuators 5 are guided in their swinging movements by a slotted plate or comb 60. which is formed with'a series .of parallel horizontal guide slots to receive and guide the actuators, and

is provided with ears 61 which receive headed screws 62 by whichthe comb plate is fixed to, the brackets 33. 'Swinging movements are communicated to the actuators by. trains of key controlled devices, one train .being provided for each actuator and,v each train comprising a} link 63 pivotally connected at its rearend to the actuator and extending fprward and somewhatdownward therefrom. The forward end of each link is pivotally connected to an upright crank arm 64 fiiied to a rock shaft 65., There are eight of these rock shafts arranged'in a series, one forward of the other at the front of the machine and below the keythe crank arms 64 are arranged at progres-= sively varying distances from the right-hand ends of their respective rock shafts 65 while the points of attachment of the links 63 to the actuators are in a vertical straight line, so that the links 63 fan or spread somewhat as they approach the front of the machine, thereby avoiding any chance of their interfering with each other when their keys are actuated. Close to its right-hand end each rock shaft is providedwitha forwardly extending crank a'rm"67 to the free end of which is pivotally connected the lower end of-an upright key stem 68, said key stem projecting upward through a guide opening 7 in the keyboard cover or plate 69 and ter- 'minating in a button or key 70. The column keys 70 are at the right of the regular keyboard, said rock shafts extending from side board (not shown), the set extending from top to bottom of the bank of keys and being suitably marked to indicate the column to which they correspond. Thus in the present instance f. the bottom key receives the number 1., the second key 2, and so on to the top-key which bears the number i87 When any one of the column,-selecting keys is depressed it acts through the train of connections comprising arm 67, rock shaft 65-, arm 64 and' link 63 on the associate actuator 57, swinging the same forward on its .a'xis 34 against the rod 59 and acting, through said rod to move the swinging frame forward and bring the contact devices or stops 44 into the path of the rear contact portions of the carriage stops24.

Means are provided for automatically releasing the carriage by .thecolumn keys, said means in the present instance comp-rising a U-shaped universal bar or bail 71 embracing between its end portions the post 30, said end portions'being pivoted at 72 to the sides of said posts, the bail depending at the front side of said post andcarrying a cross rod 73 on which is loosely pivoted an arm or connecting link,74, said arm extending rearward and being twisted so that its rear portion is horizontal and may pass between two of the actuators 57. This horizontal portion is formed with an elongated slot which loosely embraces the'rod 59, the construction being such that when the swinging frame is moved forward the rod 59, acting against the forward end of the slot 75, actuates the link or device 74, pushing the same forward, and causing it to swing forward the bail 71,.the rod 59 in this instance acting as a universal bar. It may here be noted that the bail 71 and link 74 may however be swung forward without affecting the rod 59 and the swinging frame on which it is supported, by reason of the lost motion connection afforded by the slot 75 and rod 59. The forward swinging movement communicated to the bail "71 is transmitted toa link 76 which is connected to a, projecting end of the rod 73'and extends upward to its point of connection with an angular lever 77 which, as shown in Fig. 2, is pivoted at 78 to the frame 9,'the opposite end of said lever being provided with a pin.7 9 which engagesthe circumferential groove 23. Said leveris also operative from a release key on the carriage. As the bail 71 swings forward the link "76 is pushed up,"acting to swingthe lever 77 on its pivot and causing the pin 79 to slide ,the clutch member 16 downward against the spring 17, thereby freeing the carriage from the control of its escapement devices and allowing it to move uninterruptedly leftward under the pull of the springdrum 8. This release of the carriage istimed to take. place just after the multiple stop 42 is brought to operative position. Consequently as the carriage moves leftward the first column stop to the right,

engaged thereby when the selector is swung into operation. Said pawl is pivoted at 81 to a horizontal ledge on the post (Fig.

6) and is retained in normal position in contact with a vertical face of said post by a spring 82 which is connected to the tail of the pawl and is also anchored to the' post. When in operation each unit turning movement of. the multiple stop causes one of the ratchet teeth to pass the pawl 80 which then drops in behind the tooth and prevents any 'end of the uppermost actuator.

backward turning movement under the influence of the spring 49. As the carriage moves leftward the operative column stops 24 will successively engage at their rear portion with successive projections 44 on the multiple stop and will turn said multiple stop step-by-step as described, the step-bystep movement continuing until the operated actuator 57 is engaged at its free or stop end by the associate projection Ben the barrel 47. Since these projections are progressively arranged it will be understood that the extent of step-by-step turning movements of the multiple stop will depend on which one of the actuators is in operation. lfhus if the 1 column selecting key is operated, the actuator to which it is connected, z'. e., the lowermost actuator, will be swung forward and positioned in the path of the lowermost projection 48, so that the.

selector cannot turn at all and accordingly the multiple stop will arrest' the carriage when it is engaged by the first or proximate carriage stop 24. On the other hand, if the 8 column selecting key is operated it will actuate or swing forward the uppermost.

actuator 57, bringing the same into the path of the uppermost stop or projection 48. and consequently the multiple stop will be turned successively step-by-step by the first seven carriage or column stops which will pass freely by it without arresting the carriage, this arrest taking place onlv when the eighth carriage stop engages with the multiple stop, at which timethe-uppermost projection 48 will be in engagement with the It will be understood that lesser extents of turning movement of the multiple stopand consequent arrest of the carriage at columnar positions preceding the eighth column will be caused by operating the column keys between the 51 and 8 keys; that the columnar position of arrest will depend on the particular column selecting key that is actuated; and that all columns intervening between the position in'which the carriage may be at the moment and the selected columnar position will be. skipped or passed, the carriage running freely until arrested in the selected and predetermine column, that is, so that the desired column on the work sheet carried by the carriage but not shown herein is opposite the printing point.

When the depressed column selecting key is released, the swinging frame and the stop or contact devices thereon will be swung back to normal position by the spring 53, and as soon as the ratchet wheel 46 is freed from the pawl 80 the shaft 41 and the devices mounted thereon will be rotated backward to normal position by the spring 49. At the same time that the other parts are returned, the actuator 57 and its key connections will also be returned to normal position by spring means, said means comprising for each actuator a coiled spring 83 which, as appears from Figs. 5-7, is

hooked through a hole in an angular extension or tail portion 57 of the actuator, the opposite end of the spring being anchored to a curved lug 84 formed on the upright plate 85 which is secured at its ends by screws 86 to the brackets 33. It will be understood that the lugs 84 extend in a vertical line lengthwise of the plate 85;; that the restoring springs 83 are arranged one above the other; and that each spring is effective to return its actuator to the rear end of the guide slot in the comb 60 which acts as a stop. After the column selecting mechanism has returned to normal position it may again be actuated to cause the advance of the carriage to another columnar position without an operation of any of the printing keys or any preliminary advance movement of the carriage being nec essary in order to clear the previously arrested carriage stop from the column selecting mechanism. lhis is a decided improvement over some prior constructions wherein it was necessary to operate several of the printing keys or to actuate the space bar several times inorderto clear the arrested carriage stop and permit the proper subsequent operation of the column selecting mechanism. The presentconstruction af- .fords the great advantage of allowing the column selecting mechanism to be immediately re-operated if a mistake has been made in arresting it; or in allowing it to be operated after only one character has been printed, and this without any need of mental calculation such as has been necessary in some prior construct1ons under similar condltions where the number of the column at Figs. 1, 3, 7 and 9. The denomination stop levers 87, of which there are eight in the present instance, are arranged in an upright positionforward of the post 30 in the parallel guide slots 31, said levers being pivoted on a rod 88 secured to the post, the upper end portions of said levers being confined'in said guide slots 31, the lower ends fanning outward to some extent and passing behind the bail 71. The denomination levers 87 vare adapted to be swung on their common fulcrum so that their upper end portions will be thrown rearward to an operative position, filling in or closing the cutaway Said crank-arm is fixed to the right-hand end portion of a sleeve 91 which surrounds and bears on one of the rock shafts 65. These sleeves91, as will be understood from Fig. 7, are confined loosely between the lefthand. supporting plate 66 and the hub portions of the crank arms 64 which are fixed to the shafts near their right-hand ends.

The crank arms 90, considered as a series,

are progressively arranged on their respective sleeves 91, the crank arm 90 on the rearmost sleeve being nearest the right-hand side of the machine while the others recede step by step toward the left. This enables the links 89 to be arranged in a series side by side in a substantially horizontal plane.

-Near its left-hand end each sleeve 91 has fixed to it a forwardly extending crank arm 92 to-the. free end of which is pivotally connected the lower end of a. key stem 93 that extends vertically upward through a. guide opening in the plate 69, being provided at its upper end with a key or button 94. The denominational keys 94 consequently are arranged in a row fore and aft of the machine at the left-hand end of the keyboard, occupying the same relative positions at this end *that the column selecting keys do at the opposite end.

The denomination keys 94 are provided with suitable indicating marks, in the pres ent instance these marks being, reading from the top downward, 7, 6, 5, 4,

3, 2,..1, It will be understood that the train of connectio'ns controlled by each of the'keys 94 may be actuated without affecting the trains controlled by the keys 70. Each bell crank comprising arms 90 and 92 and the elongated hub portion 91 may be actuated by its key 94 without affecting the shaft 65 on which it bears and which acts asits fulcrum. Also each bell crank comprising arms 64 and 67 and the elongated pivot portion or shaft '65 may also be actuated by its'associate key 70 without affecting the sleeve 91 which bears on it, and through which the shaft 65 extends. When one of the'keys 94 is actuated it operates through the train of devices comprising arm 92, sleeve 91, arm 90 and link 89, on the connecting stop lever 87, swinging the upper end of said lever rearward through the cutaway 32 into the path of the forward edge portions-0f the stops 24. At the same time the lower arm of the lever 87 swings forward and acts against the universal bar or bail 71 which lies in front of the set of levers87'. As a result said bar is also swung forward and acts through the train of devices comprising link 76, lever 77 and pin 79 to lower the clutch member 16 so that the carriage is automatically released. The release is so timed that after the actuated stop lever 87 is positioned the carriage is freed and will move leftward until arrested in the predetermined denominational position by the engagement of the proximate carriage stop 24 with the actuated or projected stop lever 87. It will be observed that the operating portion of this stop lever extends across the opening 32 and is so arranged that it is hacked or reinforced on three sides; that is to say, above, below and at the front of the portion or point which is directly engaged by the stop 24. As a result of this backing or reinforcing, liability of bending or distorting the stop lever, as a result of impact from the column stops, is reduced to a minimum, thus doing away with objections found in prior constructions, in which as a result of such distortion the parts were either prevented from acting or else acted imperfectly producing inaccurate results.

When the depressed denomination key 94 is released the parts will be restored to normal position by restoring devices which comprise at the lower end of the stop lever, while the By my present invention I provide a very I compact and comparatively simple construction, which has been found in practice to work efiiciently 1n the reproduction of tabulating work involving. column skipping or selecting denominational or decimal operations. 'lhe mechanisms may be applied to the machine without interfering with other parts, and may be removed with little trouble, the principal operations to this end 1 compr1 ingthe removal of thecross bar 28 by Letters Patent, is

and the plates 66, which provide the primary supports of both sets of mechanisms.

Various changes may be made without departing from my invention.
