A @riginal application filed June 29, 1910, Serial No. 569,502. Divided and this application filed May 27, 1913.
Y Serial No. 770,110.
To all 'whom it may concern Be it known that I, WALTER WRIGHT, a citizen of the United States, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following 1s a specification.
This invention relates to an improvement intypewriters, and more especially 1n c onnection with carriage and platen-operatlng mechanism, and isa division of my application No. 569,502, filed June 29, 1910.
An object of this invention is to control the movement of a power-driven carriage of a typewriter, both as to its ektent and dlrection, whereby it can be drlven by motlve means, in either direction, to any polnt desired.
A further object of this invention 1s to operate the platen of a typewriter for hnespacing concomtantly with the return movement of a motor driven carriage, whereby as the carriage is returned each time, the paper on the platen is spaced up a l1ne automatically, so as to be ready for a new l1ne of typewriting.
In the embodiment used to illustrate this invention, the carriage of the typewrlter, which is of the Underwood type, obtains its movement from motive means shown in the form of an electric motor which is connected through the intermediary of gearing to the carriage. This gearing includes a slip clutch which permits the carriage to be held stationary by the usual escapement mechanism, while the motor rotates until such time, as at the actuation of the typewriter keys, as 1t is desired to move the carriage. The gearing is so arranged that it normally tends to drive the carriage in a letter feeding` d1- rection, but lis provided with a reversingmechanism embodying a shiftable clutch,l
whereby the direction of movement of the carriage, caused by the gearing and the motor` can be reversed.
The movement of the carriage in a letter feeding direction is controlled in part by the typewriter keys, which operate the usual Underwood escapement mechanism, to permit the'motor to drive the carriage step-bvstep as each character-key is struck. i This movement is also controlled. by tabulating keys which disconnect the carriage from the escapement mechanism, so that it can be freely driven by the motor until one of a plurality of adjustable stops on the carriage has been engaged by obstructing 'means brought 1nto play by the tabulating keys. These tabulating keys can also be used to bring the carriage back in a return direction, predetermined distances, dependent on the particular tabulating key struck. This is accomplished by first depressing a key which shifts interponent mechanism into the path of certain projections moved by the tabulating keys, so that said tabulating keys will operate said interponent mechanism to shift the above-mentioned clutch, which is oo nnected thereto, and thus reverse the direction of drive of the carriage.
In order to return the carriage completely after a line has been written, another key may be struck, which, unlike the tabulating keys, does not interpose any obstructions into the path of the carriage, and yet shifts the interponent mechanism to a position where it operates the clutch to reverse the drive; the escapement. mechanism being of such character that it does not interfere with the return movement of the carriage. Provision is made whereby a single column of figures can be written and the carriage automatically returned by the return key which shifts the direction of drive from the motor and at the same time actuates platenoperating mechanism, so as to rotate the platen for the purpose of line-spacing the paper thereon, whereby the paper will be automatically brought to the beginning of the column and spaced up to the next line by the striking of the return key.
Other features and advantages-will hereinafter appear.
In the accompanying drawings, Figure 1 is a fragmentary view in side elevation, showing the mechanism in its normal relation when the carriage can move step-bystep in a letter-feeding direction. Fig. 2 is a fragmentary view similar to Fig. 1, showing the control key actuated to shift the interponent mechanism into the path of the tabulating key mechanism, so that the latter can shift the clutch and actuate the platen. Fig. 3 is a View similar to Figs. 1 and 2, showing the. return key actuated so as to completely return the carriage and concomitantly operate the platen for line-spacing.
` Fig. 4 is an enlarged fragmentary top plan opposite side to that shown in Fig. 2.
Referring more particularly to the separate parts of this invention as embodied in the form shown in the drawings, and as applied to an Underwood machine, l indicates keys which operate levers 2 to swing through the intermediary of bell cranks 3 type bars 4, so that the latter will strike rearwardly against the front side of a platen 6 mounted to rotate on a carriage 7, which in turn is mounted to slide back and forth in the usual manner on one or more tracks or rails 8. Each of the type bars 4 is provided with a heel 9, which is adapted to engage a universal bar 10 when any one of the type bars is operated, so that the latter will shift back and forth with the aid of a spring-pressed arm 11, a pair of pawls 12 and 13, so as to permit an intermittent rotation of an escapement wheel 14 withl which the pawls engage.
The escapement wheel 14 is loosely mounted, but connected to an escapement pinion .15, by one or more pawls 1G, in such a manner as to permit the rotation of the pinion 15 in-one direction but to prevent its rotation in the opposite direction, unless the pawls,12 and 13 permit the escapement wheel 14 to rotate. Inasmuch as a rack 17 normally engages the escapement pinion 15 and is connected to the 'carriage, this arrangement will permit the letter-feeding movement of the carriage step-by-step at the actuation of each key, and will also permit the return movement of the carriage, without he actuation of the escapement wheel, inasmuch as the pinion 15 is free to rotate in a return direction relative to the escapement wheel. The carriage 7 in this instance, is traversed by a motor 18 which is shown in the form of an electric motor, but might be ofl any other suitable type so long as it will give the power necessary to move the carriage. The motor 18 is connected to the` carriage 7 so as to traverse the same through the intermediary of gearing, indicated in general by the numeral 19.
Considering the specific type of gearing shown, it will be seen that the motor 18 is provided with a shaft 20 to which are connected clutch arms 21, which engage internally of a friction drum 22, so as to form a slip friction clutch which will permit the rotation of the motor 18 while the carriage remains stationary when held so by the eseapement mechanism. The clutch drum 22 is connected to a bevel gear 23, which meshes with a bevel gear24 on a shaft 25, on the opposite end of which is provided a bevel gear 26 meshing with a pair of bevel gears 27 and 28, both of which are loosely mounted on a shaft 29. Either of the bevel gears 27 or 28 is capable of being connected in driving relation with the shaft 29 by means of A a double clutch 30,.which is splined on the shaft 29 and is provided with upper and lower teeth capable of engaging corresponding teeth in the gears 27 and 28 so that when the shaft 29 is driven, it will in turn drive a gear 31 provided adjacent its upper end, so that a rack 32 meshing with said gear 31 may be driven in either direction. The rack 32 is secured to the carriage 7 in any suitable manner, so that the movement of this rack will be transmitted to the carriage, thus forming the completing unit in the chain of gearing connecting the motor 18 with the carriage 7.
The clutch is normally in engagement with the gear 28, so that the shaft 29 will be rotated in such a direction as to tend to move the carriage 7 in a letter-feeding direction, which movement however is only permitted `When the escapement mechanism is operated or released through the type keys 1, or other means to be described. In order to reverse the direction of the carriage, the clutch 30 may be shifted up into engagement with the bevel gear 27 so as to connect this gear in driving relation with the shaft 29 by means of a lever 33 which has a pin 34 engaging in a groove 35 provided in the clutch 30. The other arm of the lever is connected by a link 36 to a frame 37 which, in fact, is a composite leve;` embodying a pair of lever arms 38 pivoted at 39 and connected by a cross bar 40 at one side. The opposite ends of the lever arms 38 are provided with arcuate slots 41, in which is adapted to slide a normally ineffective interposable universal bar 42, so as to render the clutch capable of being operated by tabulating keys 43 through the intermediary of the lever frame 37 and the connecting linkages, thereby forming a portion of the interponent mechanism through which the tabulating keys may operate the clutch.
The tabulating keys 43 are mounted on levers 44 which are pivoted intermediate their ends and are adapted to engage vertical bars 45 at their rear ends, so as to raise the upper ends of the latter to positions where they will obstruct the movement of the car.- riage 7 by engaging with any one of a plurality of stops 46 adjustably mounted on. a rack 47 which is secured tothe carriage 7 in any suitable manner. It will be seen that when the bar 42 is shifted to its innermost position nearest the pivot point 39 of the lever frame 37, it Will overlie a series of projections or lugs 48, one of which is mounted on each of the bars 45 so that when one of the tabulating keys 43is actuated, if.
the bar 4 2 is superposed above this projection, the lever frame 37 will be lrocked so as to shift the clutch from the position indicated in Fig. 5 to a position in which it will connect the gear 27 in driving relation with the shaft 29, (Fig. 3) so that the carriage 7 Will be traversed in a return direction, that is to say, in a direction opposite to a letter-feeding direction. The lever frame 37 and the clutch will be automatically returned to their normal position by means of a compression spring 49 when the pressure on the tabulating keys has been released. Of course it is to be understood thatthe tabulating keys 43 are used more generally to cause the carriage to run in a letter-feeding direction to predetermined positions, determined by the stops 46 and the particular tabulating key struck, so that the machine can be used in tabulating columnsof typewritten matter. In this case, it is of course necessary to relieve the carriage of the restraining effect caused by the escapement mechanism. For this purpose, the bars 45 are provided with projections or lugs 50, any one of which is adapted to engage a universal bar 51 on a lever 52 connected to a link 53, so as to rock a lever 54 carrying a roller 55, which underlies the rack 17, so as to lift said rack from engagement with the escapement pinion l5.
Inasmuch as the tabulating mechanism is normally used for forward or letter feeding movement of the carriage, the bar 42 is normally in the position shown in Figs. 1 and 7, where it is held by a rock shaft 56 having a pair of crank arms 57 provided with slots through which the bar 42 extends.
The rock shaft 56-is also provided With an arm 58 to Which'is connected a link 59 join# ing said rock shaft 56 with another cranked rock shaft 60, which is connected through the intermediary of a link 61 to a bell crank lever 62 mounted at the front of the machine and provided with a key 63 so as to form one of the bank of keys of the typewriter. The key 63 is normally held in its raised position by a spring 64 which is connected to the link 61, and Inormally forces said link to its foremost position. It will thus be seen that the key 63 forms a control,
which, on being depressed, will shift the bar 42 into a position superposed above the lugs 48, whereby the tabulating keys 43, instead of acting to cause a movement of the carriage in a letter feeding direction, Will, throughl the reversal of the clutch 30, cause a return movement of the carriage 7.
In order to relieve the operator of the Written,
-this connection that necessity of holding the key 63 depressed While selectin the particular tabulating key to be struck, t ere is provided a lock or latch 65, which has a notch 66y adapted to engage a pin 67 on the key lever 62, so as to lock the key 63 in its depressed position. A spring 68 acts to force the notch 66 into engagement with the pin 67. The key 63 can be readily released by shifting the lock 65 against the tension of the spring 68.
The stops 46 are `of a thickness less than that of a letter space, so that when'the carriage is arrested by one of the bars 45 through the actuation of a tabulating key 43 in a letter feeding direction, the arrest will take place at a point corresponding to one letter space, or 1f numerals are being to one denomination, and'when the carriage is stopped while moving in the opposite direction, the point of rest with the same stop and tabulating key will correspond to the next adjacent letter space or denomination. This is taken care of as illustrated in Fig. 6 by designating the tabulating keys with tWo distinguishing marks, one for forward tabulating and the other for backward tabulating. It will be seen in if the carriage is stopped while moving in a forward direction when the tenth tabulating key from the right is struck, the position of the carriage will correspond to the tens column, and when the same key is struck while the carriage is moving in a return direction, the position of the carriage will correspond to the units column.
It will be seen that while the tabulating keys are very useful for returning the carriage to different predetermined points according to the particular tabulating key struck and the stop on the carriage, it is often desirable to completely return the carriage to its initial position from'which it can be once more fed stepby-step in a letter feeding direction. For this purpose, there is provided a special key 69 which is similar to the tabulating keys and secured to a lever 70 pivoted intermediate its ends, the said lever 70 being adapted to actuate a vertical bar 71 somewhat similar to the bars 45 and provided toward the top with a lug 72 forming a means for operating the bar 42 when the latter is superposed above said lug, so that the clutch 30 can be shifted so as to reverse the direction of travel of the carriage. The bar 71 however differs from the bar 45 in that it is not necessary to provide it with a lug corresponding to the lugs 50, because of the fact that the pinion 15 is permitted to rotate in a direction'permitting the return movement of the carriage by the slipping of the pawls 16. Further, the bar 71 is not of suflicient length to project into such a posi# tion that it will obstruct the movement of the carriage by engagement with any of the stops 46. This feature will be clearly seen by reference to Fig. 7.
As has been seen before, the bar 42 is not normally superposed above the projections 48 and 72, so that the bar 71 would be unable to actuate the interponent mechanism to reverse the drive from the motor to the carriage by shifting the position of the clutch 30 unless some means is provided for shifting the bar 42 to a position in the path of the lug 72. However, the lever 70 on which the return key 69 is mounted is connected by a link 73 to a rocker cam 74 pivotally mounted in juxtaposition to the link 61, s6 that the cam edge thereof will engage a pin 75 provided on said link 61, so as to force said link 61 toward the rear when the key 69 is depressed, and thus shift the bar 42 to a position above the lug 72, whereby the key 69 may shift the clutch 30 through the interponent mechanism. In order not to V disturb the control key 63 during this actuation of the link 61 by the return key 69 said link 61 is connected by a pin-and-slot connection 76 to the lever 62 of the key 63. In order that the bar 42 may be positively shifted to a position above the lug 72 before said lug is raised, there is allowed a certain amount of play, as will be seen by reference to Fig. 7, between the rear end of the lever i 70 and the bottom end of the bar 71, the
bar 71 being supported by a pin-and-slot connection 77 which limits its downward movement.
In cases where it is desired to obtain a return motion of the carriage through the simple depression of a key, it is also desirable to have the platen actuated automatically concomitantly with the return movement of the carriage, so as to provide for line spacing. This is accomplished in this case by connecting the platen-rotating mechanism so that it will be operable whenever the interonent mechanism is shifted to a position such that the clutch can be reversed. For this purpose the bar 40 on the lever frame 37 is connected by a link 78 to an arm 79 splined on a shaft 79a on the carriage, to
which shaft is fixed a rock arm 79b which actuates a link 80 supported at its opposite end by an arm 81 swingingly mounted on the platen shaft 82. of the platen 6. The link 8O carries a spring-pressed pawl 83 which engages a ratchet wheel 84 connected to the platen 6, so as to rotate the same. It will thus be seen that the carriage is moved in a return direction by a reversal of 'the clutch, and that the platen at the same time will be rotated so as to bring the paper thereon up to a fresh line. Of course the usual linespacing mechanism found on the Underwood machine can be used just the same. This line-spacing mechanism usually embodies a handle or lever 86, which operates to force rearwardly a spring-controlled slide 87 carrying a pawl 88 which co-acts with the ratchet Wheel 84. The aforementioned handle or lever is also usually effective to return the carriage.
As stated above, the lever frame 37 and the mechanism connected thereto are returned to normal position by the compression spring 49, which likewise acts to turn the `platen-actuating mechanism to its normal position. Springs 85 return the bars 45 and 71 to their normal depressed position, and thus raise the front ends of the tabulating keys 43 to their normal positions.
In the operationy of the device, it will be seen that as the character keys 1 are struck, the type bars 4 will strike the platen 6 actuating the escapement mechanism so as to permit the carriage to move step-by-step under the impulse of the motor 18 in the letter feeding direction, inasmuch as the clutch 30 normally connects the shaft 29 in driving relation with the gear 28. If it is desired to return the carriage partially for any purpose to a predetermined point, it is merely necessary to strike one of the tabulating keys 43 after having first, how ever, depressed the control key 63 to a position where it will force the bar 42into the path of the projections 48 onthe bars 45. The depression of any one of the tabulating keys will thus raise the corresponding projection 48 so that it willrock the frame 37, lifting the clutch 30 through the intermediate linkages, so as to connect the upper bevel gear 27 in driving relation with the shaft 29, and thus reverse the direction of movement of the/carriage 7, until the particular tabular stop 46comes in engagement with the particular bar 45 actuated by the depressed tabulating key 43. The carriage will then be'stopped in its motion while the motor 18 still rotates if desired, in view of the fact that the slip clutch comprising the drum 22 and the clutch arms 21 permits this relative movement. This slip clutch also comes 'f into play while the carriageis held from movement in a letter-feeding direction by the escapement mechanism. If the desired return movement has been obtained, the carriage can again be traversed in a forward or letter-feeding direction after thekey 63 has been released by manipulating the lock 65. If any one of the tabulating keys is struck, after this operation, the carriage will run forward a predetermined amount until one of the stops carried thereby en gages the counter-stop 45 corresponding to the particular tabulating key struck, the clutch in the meantime having been forced down by the compression spring 49 returning the connecting linkages.
If it is desired to completely return the carriage, it is merely necessary to depress the key 69 without a previous depresison of the key 63 as the key 69 is connected, so as /f'ing the extent of movement of said carriage ywill not only shift the clutch so as to re- .Y
verse the direction of travel ofthe carriage,
but will also actuate the ratchet mechanism for rotating the platen so as to bring the paper thereon up "co/a new line.
