TYPAE-CWRITING MACHINE.

SPECIFICATION forming part of Letters Patent NoL 608,634-., dated August 9, 1898.

A nmiei filed April 5,1893.

To all whom it may concern.-

Be it known that I, STEPHEN MQBALZER, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new andjuseful Improvements in Type-WritihgjMachines, fully described and represented in the following specificationand the accompanying drawings, forming apart "of the same.

This invention relates to type-Writing machines, and especially to that class of machines in whichthetype are grouped upon one or more carriers as distinguished from machines in which each type is mounted independently, the most common form of machines of this class being that known as wheel machines, in which the type are placed upon a rotating carrier, such as a wheel or segment, and the latter rotated in one or both directions to position it for the impression of the desired character, the impression being made either by a hammer or by the movement of the type-carrier against the paper. The machines heretofore constructed on this principle have not been found satisfactory in operation; chiefly on, account of the difficulty of securing accurate positioning of the type-carrier for the impression of the desired character and its certain retention in such position during printing, especially at a high rate of speed or after wear of the mechanism by use.

One of the special objects of the present invention is to provide an improved type-movement for such machines by which the typeoarrier is under positive control and positively locked in position before and during the action of the impression mechanism, so that a correct impression is secured at any rate of speed at which the machine can be operated.

Vhile the improved type-movement by which the type-wheel is positioned and held during printing-is applicable generally to machines of the class referred to, whether the impression be produced by the movement of the type-carrier against the paper or by a hammer pressing the type against the paper or the paper against the type, it is of especial value as applied to machines in which the typcrarrier is moved against the paper Serial No. 469,224. (l lo model) for printing; and a further object of the invention is to providean improved machine of this special class. Such machines are es pecially liable to inaccurately position the typecarrier and make imperfect impression, especially when operated at high rates of speed, because the type-carrier is liable to be moved bodily out of position before the type-carrier is properly positioned or to yield so as to permit the type-carrier to overthrow in the positioning operation even with the devices heretofore used for locking the typecarrier in position during the impression. This difiiculty is avoided in accordance with the present invention by positively locking the type-carrier against bodily movement during the action of the positioning mechanism. An important improvement is secured also by locking the key, type-carrier, and positioning mechanism together during the impression movement, so that these parts all move together as a single construction after the type-carrier is positioned. When these features are combined with the improved type-movement by which the type-carrier is positioned, the carrier is first brought into and locked in position for the impression of thecharacter corresponding to the key actuated, during which time the carrier is positively held against bodily movement, and then the type-carrier releasedto permit bodily movement and moved against the paper for printing, While the key, type-carrier, and positioning mechanism are all looked together during the bodily movement of the carrier and the type-carrier still locked in position for the impression of'theproper character. There .are preferably provided also means by which when any key is actuated all the other keys are locked against movement, and thus held until the type-carrier and type-movement have returned to normal position.

In connection with the construction. of a machine embodying the main features of the invention there have been devised also certain specific features of construction and combinations of devices, which in themselves form parts of the present invention.

For a full understanding of the invention a detailed description of a machine embodying all the improvements in their preferred form will now be given in connection with the accompanying drawings, forming a part of this specification, and the features forming the invention specifically pointed out in the claims.

In the drawings, Figure 1 is a plan view of the machine. Fig. 2 is a section on the line 2 of Fig. 1. Fig. 3 is ahorizont-al section, on an enlarged scale, taken below the top plate of the machine, the position of the platen and feed-rack being indicated in dotted lines. Fig. 4 is a vertical section on the line 4 of Fig. 3, looking to the rear, with the paper-carriage. Figs. 5 and 6 are vertical longitudinal sections on the line 5 of Fig. at, showing the parts in different positions, the ribbon-movement being omitted. Figs. 7 and 8 are detail plan views of the type-movement, corresponding to Fig. 3, but showing the parts in different positions. Fig. 9 is a cross-section on the line 9 of Fig. 3, lookingto the left. Fig. 10 is a central section through the wheel frame. Fig. 11 is a detail plan of the ribbon-feed. Figs. 12 and 13 are respectively an end view and central cross section of the carriagespring construction. Fig. 1 1 is a detail hereinafter referred to.

The scale of Figs. 1 and 2 is half size and of the others full size of a machine embodying the invention in convenient form.

The frame of the machine is shown as formed of the base-plate A, the two side frames B O, supporting the carriage, and a top plate D, mounted on standards E on the base-plate A, this top plate D supporting the type-wheel and operating parts therefor and the ribbonmovement and covering the machine between the carriage and finger parts of the keys. It will be understood, however, that a frame of any other suitable construction may be used.

The type-carrier, as shown, consists of a wheel F, which is loose on a sleeve 10, extending through slot 11 in the top plate D, this sleeve 10 being carried by the wheel-frame, which, as shown, consists of a bar 12, pivotally mounted in a bearing 13, carried by the topplate D, the bar 12 being provided with a hollow hub 14, mounted in said bearing, so that the bar 12 is supported just below the under side of the top plate D. If but one row of type were to be used 011 the wheel F, it might be mounted rigidly on a shaft carried by the bar 12 and projecting through the top plate D; but it is preferable to use a plurality of rows of type, so as to diminish the positioning movement of the type-wheel, and the typewheel is shown mounted as usual in such constructions, a shaft 15, by which the typewheel is actuated, passing through the sleeve 10, which forms a bearing therefor and being provided at the top with a forked arm 16, engaging a pin 17, carried by the type-wheel, so that the type-wheel rotates with the shaft 15, while free to slide upon the sleeve 10, the typewheel being provided with the usual collar 18, engaged by any suitable devices for shifting the type-whecl to change the row of characters.

The shaft 15 carries at its lower end, below the bar 12,a cross-piece 19, to one end of which is pivoted one arm of a three-armed lever to, this lever forming a positioning member, by the movement of which the type-wheel is rotated into position for the impression of the character desired and being provided with two other arms 21 22, extending at right angles to the arm 20. The lever a is carried by .a rod 0, to which it is pivotally connected at the junction of the three arms 20 21 22, this rod being supported by and sliding in brackets 23, depending from the top plate D, the rod 0 being drawn toward the front of the machine and normally held in this forward position by a spring 2 1, secured to the pin in the top plate D and to the end of the rod 0. The arm 20 of the lever a is connected to the cross-piece 19 by a stud or pin 1 on the cross-piece entering an opening in the arm 20, which is preferably made a little larger than the pin, as shown in Fig. 14, for the purpose presently to be described. The opposite end of the cross-piece 19 carries a similar pin 2, entering a long slot in a link 26, which is carried by and pivotally connected at its opposite end to a rod 1), similar to the rod 0 previously described and mounted in the same manner in brackets 23, this link forming a stopping member by which the type-wheel is stopped and held in proper position when positioned by the movement of lever a.

It will be seen that in the normal position of the parts, as shown in Fig. 3, the typewheel and shaft are at dead-center to the lever a in the line of bodily movement and also at dead-center relatively to the link 26, as the pin 2 is diametrically opposite the pin 1. By the rocking of the lever a, therefore, the typewheel and its shaft 10 will be thrown off the dead-center, and then the wheel, if necessary,

rotated further by the bodily movement ofthe lever, this being permitted by the slot in the link 26, this link serving to stop and hold the type-wheel in position by the engagement of the pin 2 with the link at one end of the slot, and the link being actuated in accordance with the movement of the lover a and the character to be printed.

The cross-arms 21 22 of the lever a carry at their outer ends pins 34, which are engaged, respectively, by plates 27 28, carried, respectively, by rods (Z c, mounted and sliding in the brackets 23 in the same manner as rods 1) 0, previously described. These plates 27 28 are cut away on their inner forward edges so as to first engage, respectively, the pins 3 4 on the respective arms 21 22 as the rods d e move rearward in the brackets 23, and then their reduced portions come in contact with the central pin 5 of the lever a,-the plates 27 28 being arranged at different levels, as shown in Fig. 9, so as to permit them to pass each other, so that either of them may engage the pin 5. It will be seen also from Figs. 5 and 6 that the pins 1 2, arm 20, and link 26 are so arranged that the arm and link IIO are at different levels, and the cross-piece 19 may thus be carried into any position, rotating in. either direction from the normal position, the arm and link passing each other.

The keys G are pivoted upon a bar H, mounted in the side frames 13 O at the rear of the machine and are each provided with a depending arm 29, which arms move be tween guides formed of teeth in a plate 30, the keys being returned to position by springs 31, connected to the keys and plate. Behind the arms 29 are mounted bails I I K, these bails consisting in the preferred form shown of cross-bars 32 in the path of the arms 29 and vertical side arms 33, by which the bails are pivoted on the bar H. The bails I I each extend over one-half the width of the machine, so as to be engaged each by one-half of the keys, while the bail K extends the full width of the machine and is actuated by all the keys. Near the center of the machine widthwise each of these bails I I K is connected by links 34 to vertical levers it" 70, corresponding to the respective bails, these levers being pivoted in brackets 36 on the base-plate A and forked at their upper ends so as to engage pins 6 on the slidingrods previously described, the levers t' 2" 7t being connected, respectively, to rods (Z c b.

It is necessary that the bails I I and the keys G should be so constructed and arranged that the keys will move the bails I I different distances, so as to position the type-wheel for the impression of the character corresponding to the key actuated. This result may be attained by varying the construction of the different keys or the construction of different parts of the bails in accordance with the keys, or any other suitable means may be used for securing this result in connection with the other features of the invention, but this result is preferably attained by the 0011- struction shown, by which a very simple, cheap, and efficient construction is provided.

In this construction all the keys are the same in construction, and the proper variation in the movement of the type-wheel is secured by adjusting-screws Z, carried by the bails I I and corresponding to the keys G, so that by the adjustment of these screws the proper movement of the bails may be secured in accordance with the key actuated. In order to secure the proper movement of the bail K by the different keys, this bail also is provided with adj ustin g-screws m, similar to screws Z. These adjusting-screws Z or may be held in position when adjusted by any suitable means, but there is shown a device for this purpose which in itself forms a part of the invention. In this construction the arms 32 of the bails are cut away so as to form forks through which the screws Z 772 pass, and be tween these forks is placed a thin metal plate 37, which rests upon the screws Z m and is pressed down upon said screws by pressurescrews 38, passing obliquely downward through the bars 32, so that by forcing in these screws the pressure of the plate 37 upon the screws Z m may be increased and the lat-- ter held firmly in position, while by loosening the screws 38 the pressure of the plate is released, permitting the screws Z m to be adjusted as desired.

The mechanism thus far described secures the positioning of the type-wheel in accordance with the character to be printed, the locking of the type-wheel in said position, and the moving of the type-wheel and wheel-frame rearward for the impression. WVith this mechanism is preferably combined a locking device by. which the wheel-frame is held positively in position during the positioning of the type-wheel, and in theconstruction shown this lockin g device serves also to lock the key, type-wheel, and frame and the positioning mechanism together during the impression movement and to lock all the other keys against movement when any one of the keys is actuated for printing and prevents the operation of a key until the key previously struck and other parts have returned to position. In this construction a locking bar or frame L extends the full width of the bank of keys G and is mounted loosely on a rod 39 at the base of the machine, so as to swing vertically below the depending arms 29 of the keys G and the bails I I K. The barL is so formed as to allow it to move upward without engaging the bails, but is provided with a shoulder 7, which normally is just below and to the rearward of the rear edges of the arms 29. The bar L is connected by a link 40 centrally of themachine to a horizontal arm 41 of the bell-crank lever n, mounted loosely on the bar II, another arm 42 of the bell-crank lever extending vertically and be: ing connected by a link 43 to an arm 44: on the rear of the wheel-frame 12. In the construction shown the arm 42 is connected to the link 43 by a pin-and-slot connection, so as to allow the arm 42 to move rearward withoutmoving the wheel-frame for a purpose presently to be described; but it will be understood that this is notessential so far as the action of the locking device is concerned and any other suitable form of connection may be used. i

The lower ends of the arms 29 on keys G are curved for a short distance from their rear edges 011 a radius struck from the center of the bar II and then cut on a curve of shorter radius or inclined so as toform a curve or incline of smaller radius or angle, the curve 8, struck on the longer radius,forming a lockingsurface coacting with the shoulder 7 as the keys are actuated to lock the bar L against upward movement,

during the positioning operation, and then the curve or incline 8 engaging the shoulder and locking the key, carrier-frame, and the bails and cooperating parts together during the impression movement, the bar L being permitted to rise as the carrienframe moves and thus hold the wheelframe positively against rearward movement rearward, as fully described hereinafter in connection with the operation of the machine.

With the construction thus far described any suitable paper-carriage, platen, and feed therefor may be used. There is shown a simple construction which will be found convenient and efficient and certain specific features in which form parts of the invention.

The carriage M is supported on front and rear rollers 45 in the frame of the machine by bars 16 47, running thereon, the front bar 47 forming the rack-bar by which the carriage is fed. The carriage is held firmly in position while readily removable from the frame by a clip as, secured to the rear of the frame by a screw 19 and overlapping the bar 16.

- By simply removing the screw a9 and clip L8 the carriage may be taken out.

The carriage M carries the usual paperfeeding roll and pressure-plate 5O 51 and the platen h, which in the form shown consists of a metal bar, over which the paper is fed by the roll and plate 51, the paper being guided as it is moved upward by the rod 53. The carriage is advanced for letter-spacing by a coiled spring, as usual in such constructions, the carriage being connected by a cord or band 54. to a hollow pulley 0, to the inside of which is attached aspring p, coiled about the bearing of the pulley. A spring construction is provided by which the tension of this carriage-feeding spring may conveniently be regulated as desired, which in itself forms a part of the'invention and is clearly shown in Figs. 12 and 13. In this construction the hub 55 of the pulley 0 runs in a hollow hub 56, which extends through and is mounted to rotate in a plate 57, fixed on the frame and carries outside the plate a ratchetwheel q and a thumb-piece r. Upon the plate 57 is mounted a finger-lever s, carrying two pawls 58, one of which will engage the ratchet-wheel q in each position as the lever is.

rocked, these pawls being so positioned that on each rocking of the lever so as to release one pawl and throw in the other the ratchetwheel will be allowed to turn one tooth. One end of the spring 19 is attached to the pulley 0 and the other to the hub 56 on ratchetwheel q, and the pulley is secured in the hub 56 by a screw 59, which forms a bearing for the pulley. By this construction the spring may readily be wound up as desired by the thumb-piece r, and in case the spring is too tight the proper tension may readily be secured by releasing the ratchet-wheel q and spring 0 step by step by the lever s.

The construction shown for releasing the paper-carriage step by step for letter-spacing consists of the common fast-and-loose pawl device 60, which is carried by a lever 61, pivoted on the frame of the carriage so as to rock vertically and connected by alink 62 to an arm 63, extending rearward from the bellcrank amounted on the bar If an d previously described in. connection with the locking movement,'so that as the bell-crank is rocked rearwardly by the impression movement of the wheel-frame the pawl device is actuated so that a letter-space movement is secured as the wheel-frame returns to position, as well understood in connection with similar carriage-feeds. It will be understood that any other suitable rack-releasing device may be used in connection with the carriage-spring construction.

For word-spacing a space-l tey N is used, which is shown as pivoted at the base of the machine and connected to the link 40, so that .by actuating this space-key the bell-crank 'lever 77. on shaft 11 is rocked rearwardly and a spacing movement secured, as in the printing operation, the pin-and-slot connection of the arm 42 to the link 43, previously described, providing for lost motion sufficient to permit this spacing movement without movement of the wheel-frame.

The shifting devices for moving the typewheel vertically to change the case may be of any suitable construction. As shown, the collar 18 011 the type-wheel is engaged by the forked end of an arm 64, carried by a pin 65, moving vertically in a central opening in the hub 1 1 on the frame 12, and this pin is raised and lowered by a bar 66, carried by one end of a lever 67, pivoted in brackets on the under side of the top plate D and actuated by two keys S S at one side of the machine, two shifts being used for three rows of characters, as usual in such constructions.

Any suitable inking device may be used, either pad or ribbon, but a ribbon is preferred, and there is shown a ribbon-feed which will be found simple and efficient and forms a part of the invention. In this construction the type-wheel is partially surrounded by a ribbon-guide 68, as usual, and the ribbon-spools R R are placed on the top plate D in front of this guide, these ribbon-spools R B being mounted in any suitable manner so as to rotate in either direction and being provided with ratchet-wheels 69 by which they are driven.

The wheel-frame carries a bar 70, extending forward and sliding on the top plate D, this bar 70 being guided as the wheel-frame moves backward and forward by a pin 9, passing through a slot in the. bar. At its front end this bar 7 O carries a pawl-carrier 71, pivoted to swing transversely to the bar and having at opposite sides pawls If, one of which en gages one of the ratchet-wheels 69 as the bar 70 moves with the wheel-frame, according to the position of the pawl-carrier 71, which is held in position according to the ratchetwheel to be actuated by notches cut in the pawl-carrier, and a small spring 7 2, entering either of said notches according to the position of the pawl-carrier and the spool to be actuated thereby. The ribbon is thus fed from one spool to the other by one of the pawls t, and when the ribbon has been thus wound entirely onto one spool the pawl-carrier 71 is shifted so as to throw the other pawl into engagement with the ratchet-wheel 69 on the other ri bbon-spool and reverse the ribbon, as well understood in such constructions.

The operation of the construction will be understood from a brief description.

In the normal position of the parts, as shown in Figs. 3 and 5, with no key depressed, the type-wheel and wheel-frame are in their forward position away from the platen 52. The sliding rods 6 c d e are all in their forward positions, and thebell-crank lever a is in its forward position, with the type-wheel at deadcenter relatively to the arm 20, all these parts being held in position by the spring 24. The locking-bar L is in its lowest position with the shoulder 7 just below and in front of the rear edges of the arms 29, and the bails I I K are all in theirforward positions. Assuming that the key actuated operates the bail I and rotates the type-wheel to the left through alarge part of its semicircumference, as shown in the drawings, the first action of the key upon the adj usting-screw Z throws the bail I rearward and through connecting-rod 34 and lever 7: moves the rod d rearward in the brackets 23, so that the rear edge of the outer portion of the plate 27 engages the pin 3 on arm 21 and rocks the bell-crank lever a, so as to throw the type-wheel off the dead-center and into the position shown in Fig. '7, the pin-and-slot connection 1 of the arm 20 to the cross piece 19 permitting this movement and preferably being so formed as to allow no lost motion, but secure the continuous movement of the wheel with the lever a. As the type-wheel is thus rotated, the pin 2 in the cross-piece 19 moves forward in the slot in the link 26, the rod 1) being stationary. The rod d has now been advanced so that the inner cut-away portion of the plate 27 engages the pin 5 at the center of the bell-crank, by which it is connected to the rod 0, and as the movement of the key, bail, and rod d eontinues the bell-crank a is moved forward bodily to continue the rotation of the typewheel to the left, the bell-crank carrying with it the rod 0 against the tension of the spring 24 and the pin 2 continuing to travel back in the slot in the link 26. At the proper time the bail K is engaged by the arm 29 011 the key being actuated through one of the adjusting-screws m, and this bail is then moved backward and through the link 34 and lever it moves the rod 12 rearward with the link 26 until the forward end of the slot in the link engages the pin 2, when the type-wheel is positioned for the impression of the letter corresponding to the key actuated and locked in this position by the pins 1 2, arm 20, and link 26 engaging the cross-piece 19 on opposite sides of the axis of the type-wheel and opposing each other.

In the construction shown, in which the type-wheel is moved against the paper for printing, the movement of the bails I K and rods (1 b is continued after the type-wheel is thus positioned and locked, so as to carry the type-wheel frame rearward for the impression of the type against the paper on platen h, the rearward movement of both the lever a and link 26 maintaining the positive locking of the type-wheel against rotation during this movement and assuring a correct impression.

NVith the wheel-frame mounted on a vertical pivot, so as to swing in a horizontal plane, as in the construction shown, it will be seen that the change of position of the type-wheel due to the are through which the frame and type-wheel swing for the impression movement is compensated for automatically by the lever a and link 26, so as to secure the impression of the face of the type squarely against the paper.

During the operation of positioning the type-wheel as thus far described the locking device for the wheel-frame has operated to hold the wheel-frame positively in position, so that the movements described, although tending to move the type-wheel and wheel frame, have produced no rearward movement of the type-wheel, but only the rotary movement requisite for positioning it for the impression of the proper character. This result has been attained as follows: As the key G is depressed and the arm 29 thrown rearward the rear portion 8 first passes over the shoulder 7 and prevents the raising of the locking-bar L until this portion 8 has passed inside the shoulder and the front portion 8 is in engagement with the shoulder, when the bar is permitted to rise during the further movement of the key, the bar still engaging this surface 8, however, so as to permit it to rise only in accordance with the movement of thekey, and thus locking the key, wheelframe, bar, and the bails and other parts of the positioning mechanism together. In the position of the type wheel and actuating parts shown in Fig. 7 the projection 29 on the key G, which is being actuated, is in the posit-ion shown in dotted lines in Fig. 5, and the surface 8 is just about to release the bar L,

IIO

so as to allow the latter to rise for the rearward impression movement of the typewheel. As the movement of the key G and bails I K continues the rods cl I) carry the type-wheel and type-frame rearward, the key, wheelframe, and positioning mechanism being locked together by the bar L and the typewheel being positively locked in position for the impression of the character corresponding to the key actuated, as previously described, and as the type-wheel moves rearward the bell-crank n is rocked rearward through the link 43 and by the connectingrod 40 raises the locking-bar L, which has been released, as previously described, so that at the time of impression all the parts are brought into the position shown in Fig. 6.. In this position it will be seen that the lockingbar L has been raised, so as to bring the shoulder 7 in the path of the rearward movement of the arms 29 on the keys, so that all the keys are positively locked against movement, and

this locking of the keys continues until the bar L is again lowered. When the impression is made, the key G, previously actuated, is released and all the parts returned to their normal position, the key G being returned by the spring 3i and the type-wheel and wheelframe being returned through bell-crank a, rod Z7, and spring 24-, and the return of the type-wheel and wheel-frame returning the bar L to its lowest position through the connections previously described. The forward movement of the rods cl 1), with the wheelframe and bell-crank a, also returns the bails I K through the levers 1' 7c and connecting-rods 34. The feeding movement takes place during the return of the wheel-frame, as previously described,the movement of the Wheelframe in opposite directions actuating the pawls through the arms 63, link 62, and lever 61. The pawlt has been carried back one tooth on the ratchet 69 on one of the ribbonspools, and on the return of the wheel from the ribbon-spool it rotates the ratchet-wheel one tooth and the ribbon is shifted. The parts are now in position for printing another character, and thus the operation is repeated.

In the operation described the bail I has been described as actuated before the bail K and the pin 2 as moving in the slot in link 26 before the link is moved; but this is only because the operation selected for illustration is that of positioning the type-wheel for the impression of a character requiring the rotation of the type-wheel through nearly a halfcircumfercnce or nearly the largest movement of the type-Wheel. It will readily be understood, therefore, by those skilled in the art that the bail K will in some cases be actuated before the bail I or I, so that the link 26 will move forward before the type-Wheel is rotated and the wheel then be rotated by the movement of bail I or I while the movement of the link 26 continues, the result being the same as previously described. The time and amount of movement of the bails I or I and K depend, therefore, upon the position of the character on the type-wheel corresponding to the key actuated, and the movement of the bails is varied in accordance with the character to be printed and their accurate movement secured solely by the adjustment of the screws Z m, the keys G in construction and movement being all the same.

It will readily be understood by those skilled in the art that the means for positioning the type-Wheel are of general application in typewriting machines of the different classes employing a type-wheel and may be used in machines of other general construction than that shown.

It will be understood that the invention is not to be limited to the exact construction or arrangement of the devices shown, but that many modifications may be made therein by those skilled in the art without departing from the invention. it will be understood also that many of the features of invention may be used in constructions not employing the other features and that the claims are intended to cover such use.

What I claim is- 1. The combination with a type-carrier, of a plurality of series of keys, a positioning member having a pivotal connection with the type-carrier, connections between said positioning member and keys for moving said type-carrier in different directions by thedifferent series of keys to position the type-carrier, and stopping mechanism controlled by all the series of keys whereby the type-carrier is stopped and held in position, substantially as described.
