Specification of Letters Patent.

Patented July 15, 1913.

Application filed October 4, 1910. Serial No. 585,186.

T 0 all whom it may concern Be it known that I, LYMAN D. BROUGH- rox, a citizen of the United States, residing in Hartford. in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Type-lvriting Machines, of which the fol lowing is a specification.

The present invention relates to those typewriting machines which are especially adapted for tabulating work, and which to this end ordinarily comprise: first, a series of column stops adjustably attachable to the carriage, to accord in. number and adjusted position to the columns or printing fields of the tabulation: secondly, a set of decimal tabulator stops, any selected one of which is adapted to be set to cooperate with the proper column stop in arresting the carriage at the desired decimal position of a column to which the carriage is thrown: and thirdly, key-operated means for releasing the carriage and setting the column stops so that any desired number of columns or printing fields may be skipped or passed over before the carriage is arrested at the selected column.

This invention is in the nature of an improvement upon the devices disclosed in my pending application No. 552,540 filed March 31. 1910.

The invention has particular reference to those machines in which the normal setting of the column stops is such as to render the same efi'ective to stop the carriage, but in which, by means of suitable key operated connections, one or more of the column stops are movable to inetl'ective position to permit the carriage to skip or pass over the columns controlled by the stops so moved.

One feature of the present invention is the provision of a connection between each of the column stop keys, and the decimal point stop of the decimal tabulator, whereby, whenever a column stop key is operated to release the carriage and set the column stop, the decimal point tabulator stop is also set tocooperate with the selected column stop to arrest the carriage, unless at the time the 0211112198 is released, some other one of the decimal tabulator stops is especially set by operation of a. tabulator key. It tol lows that where in the present invention,

the carriage is to be arrested at the decimal point position in the selected column, no decimal tabulator key need be operated. The operation of a single key, (the desired column stop key), not only releases the carriage, and, by actuation of the column stops, selects the column to which the carriage is to be skipped; but also sets the decimal point tabulator stop to cooperate with the selected column stop to arrest the carriage.

Another object of the invention is to provide a. novel form of column stop and stop carrier, and means for setting the latter on the carriage, whereby the attachment of the stops to the carriage may be secure and of ample strength to resist the shocks imposed upon the column stops in arresting the car riage after a run, and whereby bending or other injury to the column stops by reason of the impact of the same against the tabulator stops is absolutely prevented.

A rack attached to, and extending longitudinally of the carriage, is av well known means whereby adjustably to secure the column stops to the carriage. The rack has commonly had two faces and the stops have straddled the rack to engage between the teeth thereof on either side. The stops have been slidable into and out of engagement with the rack. According to certain features of the present invention, this structure is much simplified. The rack has but a single face, thus permitting of a swinging movement of the stops in engaging and disengaging the rack; and the stops are so shaped that the shock of stopping the carriage is distributed to several of the teeth of the rack.

Certain features of the invention relate to a novel means for operating one or more column stops from a single stop key to render ineffective all of the stops so operated, and for returning the parts to normal position, together with the decimal point tabulator stop.

Other objects and features of the invention will more fully appear upon reference to the accompanying drawings in which,

On the main frame 1 of the machine is mounted the carriage frame 2 which carries the platen 3 and various other parts. The carriage frame driven in the usual manner by a drum sprin (not shown) and a pinion a, forming part of an escapement mechanism, normally engages arack 5 on the carriage frame to control the stepbystep or letter feed of the carriage. The rack 5 is supported on arms (3 pivoted at 7 to either end of the carriage, so that, upward movement of the arms 6, lifts the rack from the escapement pinion 1 to release the carriage from the escapcment mechanism when it is desired to jump the carriage from one column or printing field to another, or to release the carriage at other times.

Mounted to have up and down movement in the main frame of the machine are a series of decimal stop plunger-s 8. These plungers are normally in depressed position, and after each operation are returned to normal position by means of springs 9, each secured at one end to one of the plunger-s 8, and at the other end to a cross bar 10 in the frame of the machine. A stop bar 2 1 limits the movement of the plungers, and determines the normal position of the same. The plungers 8 rest upon and articulate with levers 11 carrying the decimal stop or tabulating keys 11. Upon depression of any of the keys 11, the corresponding plunger 8 elevated, and cooperates with one of a number of column stops to intercept and arrest the carriage in the proper position after each jump. The plunger-s 8 each have a shoulder 8 and a universal bar 12 fast to a rock uhflft 13, extends crosswise over the shoulders S so that when any one of the plungers 8 is elevated, the bar 12 causes the shaft 13 to be turned. Fast to the shaft 13 is also a lever 1 The lever 141 is connected to a link 15, and the link 15 to a lever 16 on a rock shaft 17. The shaft 17 carries an arm 18 bearing at its outer end against an arm or lever 19 journal-ed on a shaft 20. On the lever 19 is mounted a roll 21 adapted when the lever is rocked counterclockwise, as shown in Fig. 1, to engage the rack 5 and lift the same out of contact with the escapement pinion 4. hen, therefore, any plunger 8 is operated by its corresponding decimal. key 11, the bar 12 is lifted up, causing the lever 14, link 15, lever 16, and arm 18 to be depressed, and the lever 19 to be rocked to release the carriage from the escapcment mechanism. Fast to the rock shaft 17 is a brake or governor mechanism comprising a pinion 22, which, when the shaft 17 is rocked to release the carriage from the escapement mechanism, engages a second rack 23 on the carriage. The movement of the carriage during the column to column movement is therefore checked by the connection of the governor through the pinion 22 with the rack 23. The return of the plunger-s S to their normal position permits of the return to nor mal position of the parts above described. The return movement of these parts is effected by means of a spring not shown, prefe'ably mounted upon the rock shaft 13. The machine as thus far described is not new with the present invention.

Fast to the carriage is a third rack 25 out only on the side which faces to the rear of the machine. Also fast to the carriage to the rear of the rack 25 is a bar 26. The column or field stops are mounted on the bar 26, and are adjustable along this bar, (see Figs. 2 and 7). These stops each comprise a sleeve 27 splined to the shaft to be adjustable longitudinally thereof; and, mounted to be rocked on each sleeve, is a collar 28. Each collar at one point carries a finger piece 29 and at another point an arm or locking bar 30. The bar 30 is of sutlicient length to engage the rack 25; and, when the stop is set, rests by means of a shoulder 31 (see Figs. 1 and 6) on the upper face of the rack. Each of the bars 30 carries at its end two or more teeth 32 which, when the bar is set, engage the teeth of the rack 25. Since there are a plurality of the teeth 32, the shock of the carriage is distributed to several teeth on the rack 25, instead of to one only. To move the bar 30 into and out of engagement with the rack, the finger piece 29 is swung on sleeve 27. T he sleeves 27 have each a ball socket 33. Each of the bars 30 (see Fig. 2) has a pocket in which there is a ball 3a and a coiled spring bearing against the same. hen the pocket in the bar registers with the socket in the sleeve 27, the ball 1 enters the socket under the action of the spring and holds the bar 30 against angular displacement on the sleeve. The ball 34: isin its socket 33 when the bar 30 is in engagement with the rack 25, and the set position of the bars 30 is has maintained.

Mounted to rock on each of the sleeves 2 is a bell crank lever comprising a long stop arm 36, which extends toward the rack 25, and a short arm 37 which depends below the shaft 26. These bell crank levers are adapted to be rocked upon the sleeves 27 between a normal (full line Fig. 6) position and a position shown in dotted lines in the same figure. Springs 36, each attached at one end to stop arm 36 and at the other end to bracket 43 forming part of sleeve n7, return stop arms 36, and arms 37, to normal posi tion after operation of the same. If any column stop arm 86 lies in its normal position, and in such position is brought by the carriage to the decimal plungers 8, a depending tooth 38 on the stop arm 36 will engage with whichever of the decimal plunger stops 8 may be elevated at that time, to arrest the carriage. The stop arm is held against lateral yield or displacement by the bar 30 to one side, and by a lug 30 on the bar to the other side.

For the purpose of operating the stop arms 36 to render the same ineffective during the operation of the machine by drawing the same out of reach of the decimal stop, so that certain columns may be skipped when desired, the depending arms 37 of the stop arm levers are each engaged and adapted to be actuated by arm 41 of a lever 4L5 pivoted on a stud 452 carried by the depending bracket 43 on the sleeve 27. Each arm 37 has a tooth 39 which intermeshes with teeth 4L0 on the arm a1 so that when the lever 45 is rocked, the arm 37 must also be rocked. It will be noted that the stop arm 36 must move in a direction reverse to that of the arm 45. The movement of the arm 37, and consequently of the stop arm 36, is limited in either direction by cars tal formed on the bracket member 43. The depending arms of the levers each terminate in a tooth or hooked end 46. For purposes presently to appear, the lever arms do are of different lengths (as shown in Fig. the arm representing the first column or printing field being of the greatest length, and the arms representing the succeeding columns being successively of shorter length. Since the final column is never skipped, the stop representing the same need not be operated from the key board, and there is consequently no lever connection to this stop (see Fig. 8).

The stop arms 36 are operated by means of the arms 4-5 from the key board as follows: Pivoted on a shaft- 47 fixed in bracket arms 48 on the frame 1 of the machine are levers 4L9 corresponding in number to the number of columns or printing fields for which the typewriter is adapted to be set.

The upper arm of each lever 49 carries at its end a plate 5-0 which lies in substantially a horizontal plane with one ec ge turned toward the actuating levers 45 (see Figs. 3 and Each of the plates 50, (see Figs. 9 and 10), except the upper plate, is cut away, as at 50, so that the longer levers in bringing their plates to the levers 45 may not be obstructed by the plates of shorter levers. The de )ill of the cut away portions is such, however, that a longer lever 49 in moving toward the actuating levers 4E5 presently engages and carries with it all the plates 50 below its own plate; and, each of the plates thus moved together then lies in position to operate its appropriate lever 45 when that lever is brought by the carriage to the plate. When, therefore, a lever 49 representing a column or printing field beyond the first column is operated to set its plate 50 in position to be engaged by its column stop lever 455 when the latter is brought by the carriage to the plate, all those plates 50 which con trol the column stops for the preceding printing fields are simultaneously set, so that, as the carriage advances, one after another of these preceding column stops is rendered ineffective and cannot be engaged by a decimal stop to arrest the carriage. For example, if the lever ll-9, which controls the third column stop is operated, that lever will set the plates 50 which operate the stops for the first and second columns, and therefore the first and second column stops, in turn, will also be rendered ineffective, so that the carriage will skip to the fourth column. The levers 49 are guided in their movements, and are held against lateral displacement, in slots 54 in a crcss piece on the frame 1.

Each lever 19 is operated from one of a number of column stop keys on the key board by means of a link or pull rod 56 connected at one end to the lower arm of lever 49 and at the other end to a bell crank lever 57 pivoted on a shaft 58 in the front of the machine frame. Each bell crank lever 57 is connected to a lever 59 pivoted at 60 or 61 to the front of the machine frame. The levers 59 carry the column stop keys These keys are numbered 2, 8, at and 5, and when operated, skip the carriage to' the second, third, fourth and fifth columns respectively. The key #2 controls the first column stop; the key #3 the second column stop; etc. Key #2 by operating and rendering ineffective the first column stop, skips the carriage to the second column; key #3 to the third column; etc. There is no column stop key numbered 1, because when the first column or printing field is desired, there is no skipping to be done, and no stop to be rendered ineffective.

The pull rods 56 are slotted at 71 where they engage pins 72 on the levers 49, so that the levers 49 may rock independently of the pull rods. lVhen a column stop key is depressed to operate any except the lowest of the plates 50, it will be remembered that the plate or plates below the one so operated are also moved. If these plates are to be moved together in this manner, although but a single column key and pull rod is operated, then the levers 49 which support the plates connected to the other pull. rods must be free to move independently of such pull rods; hence the slots 71. Coil compression springs 62 return the pull rods 56 rearward to normal position after each operation. lVhen the levers 49 are in normal position, the pins 72 rest at the rear ends of the slots 71.

Levers

57 and 59 with keys 55 are returned to normal position by pull rods 56 to which they are connected.

It has been shown that the plate 50 car ried by the lever 19 which controls the column #1 stop is operated whenever any of the levers a9 is operated, because all the levers of the higher plates must engage the lowest plate in advancing toward levers The lever 4-9 controlling the column #1 stop in returning to normal position, may therefore be utilized to return all. the levers 49 of the other plates to normal position. To this end there is pivoted at 63 to a bracket 64 on the frame, a bell crank

lever having arms

66 and 69. The arm 66 of this lever engages a pin 67 on the column #1 lever 19. The arm 66 is engaged by a spring 68, also attached to the bracket 64, and acting through arm 66 to return attached lever 49 to normal position after each operation. The plate 50 carried by this column #1 lever 49, in returning to normal. position, engages and forces back with it the longer levers -19 of any of the higher plates 50 which may previously have been set. Each lever 415, as soon as disengaged from its plate 50, is free to return to normal position, and does so by virtue of spring 36, acting through its stop arm 36. The other arm 69 of the bell crank lever, pivoted at 63, projects toward the decimal plungers S, and is bent to pass under a shoulder 70 on that one of the plungers 8 which is employed to arrest the carriage at the decimal point. This is the first plunger 8 to the left looking from the front of the machine. Whenever the lever arm 69 is raised by operation of the first column lever a9, acting through the arm 66, the decimal point plunger 8 is lifted by the engagement of the arm 69 with the shoulder 70, so that this plunger is set for the column stops. Since the lever arm 69, by virtue of its connection to the #1 column stop lever 49, is actuated every time any of the column stop keys is operated, it follows that whenever any of these keys is operated the decimal. point plunger 8 is also operated. To oper ate the decimal point stop at each column it is therefore unnecessary to operate a key of the decimal. tabulator. When, in the tabulating work, some other decimal stop is the one desired, such stop is operated from its particular tabulator key as heretofore described; and, although the decimal point stop is also necessarily operated whenever any of the column stop keys is operated, it is in such instances inactive, because, before the carria reaches the decimal point stop, it is arrested by whichever of the other decimal stops may have been lifted to set position.

In addition to the cams 59. at the righthand ends of the plates 50, it is also desirable to have cams 51 at the left hand ends of these plates; because there is a liability of the operator running the carriage back to begin a new line while a column key is depressed. In such instances, except for the cam 51, the column stop lever 45 which was in set position would strike its plate 50 squarely, and might be bent or injured by the blow. A. lever 45 striking a cam 51 is swung idly back.

Assuming that the carriage has just been returned to initial position, and that it is desired to jump it to the fourth column or printing field, and there to arrest it at the decimal point position of the column: the column key 55, numbered 4% is depressed. This key controls the third column stop. .i' hen the key is depressed, the levers and 57 are rocked to pull forward the proper rod 56, compressing its spring 62. The pins 72 normally rest at the rear ends of the slots 71 in the rods 56; so that, as the rod 56 goes forward, the lower arm of the corresponding (third column) lever 49, operated by key numbered 4E also swings forward; and the upper arm of this lever 49, rearward, with its plate 50, to set position. The upper arm of the third column lever 49 in swingin rearward engages and carries with it to set position, the plates 50 of the second and first column levers 49, so that as shown in Fig. 3, all the plates except the upper plate, which is operated from key numbered 5 are in set position. The levers 49, carrying the first and second column stop plates 50, are free to be thus moved to set position. without corresponding movement of their pull rods 56, by reason of the slots 71.

As the first column plate 50 moves to set posit-ion, its lever 49 is rocked, and rocks the bell crank lever 6669 around its pivot 63 against the action of the spring 68. The arm 69 of this lever thus swings up, and, by engagement with the lug 70 on the decimal point plunger 8, lifts that plunger, against the action of its spring 9, to set posi tion. The decimal point plunger 8 in moving up engages and rocks the bar 12 on the shaft 13, and through the connections 14:, 15, 16, 17 and 18, rocks lever 19 to lift the rack 5 from the escapement pinion 4, thus releasing the carriage. The movement of the rock shaft 17 brings the governor into connection with the rack 23 through the pinion 22 just before the rack 5 is lifted free of the escapemcnt pinion 4. The carriage then moves rapidly to the left under the control of the governor. As the carriage advances, it carries with it the column stops, all of which have previously been set by means of the rack 25 to any desired position. he first column stop is the first to reach the bank of plates 50. It finds its plate 50 in set position intercepting the path of its tooth 4L6 on the lever. The tooth 46 engages the cam 52 of its respective plate, and in being forced back by the cam, rocks the lever to lift the first column stop arm 36 to ineffective position. The cams 52 are positioned so that this action occurs before the column stop arrives at the decimal stops. The plate is of suflicient length to hold the first column stop arm 36 elevated until ithas passed the last decimal stop, to wit, the decimal point stop. The decimal point stop is in its elevated set position, but the first column stop arm 36 has been lifted too high to engage it, and so the carriage moves on without stoppin and the first column or printing field is skipped. The second and third column plates 50 are also in set position, and so the second and third column stop levers 45, in turn, engage each its respective plate 50, to lift each its respective stop arm 36. The stop arms 36 of the second and third columns, like that of the first column, therefore pass the decimal point stop, and the carriage continues, without stopping, toward the fourth column. The fourth column stop lever 45 on arriving at the bank of plates 50 cannot engage its plate 50; because this plate lies above the upper end of the third column lever 49, (operated from the stop key numbered a and so has not been moved rearward to setposition by the key numbered 4 The fourth column lever 45 is therefore not rocked backward, as were the preceding levers as. The fourth column stop arm 36 consequently remains in normal, depressed, position. This stop arm therefore presently engages the decimal point plunger 8, and the carriage is arrested at the decimal point of the fourth column. The column stop key, numbered 4, is then released. Springs 62, on rod 56 connected to this key, returns levers 57 and 59, and the key to normal position, determined by suitable stopping surfaces, on the frame, which are engaged by the levers Spring 68 acting through lever 66, is then free to return not only the first column lever ll) and plate 50 to normal position, but, acting through these elements, to return second and third column levers 4.9 with their plates 50, also to normal position; all the levers L9 coming to rest with pins 72 at the ends of slots 71. When the spring 68 swings lever 66-69 to normal position, the spring 9 attached to the decimal point plunger 8 lowers that plunger until stopped by the bar 24; and, simultaneously with the return of the plunger 8, the carriage is disenaged from thegovernor and engaged with the escapement mechanism in the usual manner through the connections described, whereupon the machine is ready for letter feed. Assuming that some decimal stop, other than the decimal point stop, is desired, the proper tabulato-r key 11 should be operated, in advance of the operationof the desired column st op. The carriage is then arrested before it reaches the decimal point stop; and the latter although set, is not reached by the column stop.

Obviously the structure shown and described is susceptible to various modifications within the scope of the invention.
