No. 823,010. Specification of Letters Patent. Patented June 12, 1906.

Application fi led January 16,1902. Serial No. 90.020.

Be it known that I, CHARLES WELLINGTON ALKER, a citizen of the United States, and a'residen't of Bridge ort, in the county of Fairfield and State of Connecticut, have invented certain'new and useful Improvements in- Type-Writing Machines, of which the following is a specification.

My invention relates to type-writing machines, and is directed mainly to the t ebar action and to the mechanism for shi ting the parts so as-to change from one case to another in order to print with any one of a plurality of types oneach type-carrier; and the invention is further directed to the typeguide construction for guiding the types in proximity to the printing-point.

y invention consists in certain features of construction and arrangements of parts,- as will be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, wherein verse bar 8, that is secured to an arm 9, pro

ecting from the rock-shaft 10 of the dogrocker 11. The feed-dogs 12 on the dogrocker cooperate with a feed-wheel 13, which is 0 eratively connected to a shaft that exten s through a fixed bearing 14, secured at 15 to the top plate 16 of the machine.

The forward end of the shaft referred to is provided with a feed-pinion with which a feed-rack 18 cooperates. The feed-rack 18 is carried by a carriage 19, that moves upon suitable traverse-rods 20, supported upon the top plate 16, and the carriage supports a platen 21. ,Each of the key-levers 3 is conlike reference characters designate corresponding parts in the various views, Figure 1 pivoted at 23 to a bell-crank is a vertical sectional view from front to rear of one form of type-writing machine embodymg my invention. Fig. 2 is an isolated detail I side view of one of the type-bar actions, the view illustrating one of the lower-case type at theprinting-point. Fig. 3 is a like view of the same, showing the parts shifted to bring one'of the upper-case type to the rintin position. Fig. 4is afront viewof t e mac 'ne, with parts broken away and others omitted for the purpose of more clearly showing other parts. Fig. 5 is a detail perspective view of the case-shifting mechan1sm., Fig. 6 is a detail perspective view of oneof the typebar actuating bell-cranks and hangers emplo ed at thefront of the segment. Fig. 7 is a ive view of another of said bell-cranks and hangers.. Fig. 8 is a detail perspective view of one of the bell-cranks and hangers used at the rear of the segment. Fig. 9 is a like view of another of the bell-cranks and hangers'eim Fig. 10 is an enlarged detail perspective View of the ty(peguide. Fig. 11 is an enlarged detail si e viewof a portion of one of the type-bars with one of the side plates removed to clearly show the means for connecting the type holders to the bar. Fig. 12 is a'detail front nected to a straight draw-link 22, which is lever 24 or24, as the case may be, and the various bellarms are connected at various points in the lengths of said bearings. All of the bellcrank levers 24 are-vertically arranged and are pivoted to hangers 25, that are segmentally arranged and are each apertured at 26 for the reception of a screw 27, by means of which the bell-cranks 24 and their hangers may be secured to the front of a vertically disposedfsegment or segmental support 28. Hangers 29 are secured by screws 30 to the rear. face of the segment 28, and these hangers support the rear set of bell-crank levers 245' r The hangers 25 and 29 are the same in construction and are secured in the same manner to the segment 28, though the hangers upon opposite sides of the segment are staggeredor alternate, as will be seen upon reference to Fig. 4, wherein the front series of hangers are each mounted out of alinement with the hangers u on the opposite side of the segment. By t "s arrangement of han ers and bell-cranks a large number of hellcranks may be mounted in a comparatively small space, considered widthwise of the machine, which is substantially coextensive edge of a type-bar.

- with the width of the keyboard and-without ICC crowding the parts and without detracting from the strength thereof by reduc ing the size of the parts. From an examination of Figs. 1, 4, 8, and 9 it will be seen that this staggered arrangement of the hangers and bell-cranks permits one arm of each of the rear series of bell-cranks 24 to be bent forward, so that it extends between the up right arms of the forward set of bell-cran 's and may each be connected to a straight draw-link 22, which in turn is pivoted at 32 to a key-lever, so that while the bell-cranks are upon opposite sides of the segment 28 they all connect with their key-levers forward of the segment, and a substantially equal leverage is provided throughout the various actions. Each of the bell-cranks 24 and 2-4 has one arm thereof connected to a draw-link 33, which has its inner end pivoted at 34 to a driving-lever 35. These links may be twisted, as shown in Fig. 4, or may be round links which are screw-threaded at their ends, where they are received in the connecting ends 33, as represented inthe other ligures. Each driver 35 is pivoted at 36 between the ends of a type-bar proper, 37, which latter is pivoted at 38 to a pivoted guidelink 39, so as to constitute what is known as a jointed type-bar. The upper end of each guide-link is pivoted to a segmental pivotwire 40, secured at 41 to a fixed cross-bar 41. Each driver 35 likewise pivoted at 42 intermediate its ends to a supporting-lever 43, that constitutes one arm of a bell-crank lever which. is pivoted on a segmental wire 44, that is supported by the vertically-disposed segment 45 and is adapted to move around said pivot-wire in ,aradial slot 46, formed in said segment, so that each type-bar proper, 37, swings around four centersone, the swinging pivot 38, another,the fixed pivot 40, the third; the pivot 42 of the driver for the typebar, and the fourth the swinging pivot 36-in the same general'manner as the type-action in the Yost machine. The arm 47 of each of the radially and segmentally arranged bellcranks 43 to 47 is rounded at 48 and projects into the slotted edge 49 of a segmental shift-plate 50. To the shift-plate 50 is secured a bracket 51, which is pivoted at 52 to a lever 53, that is pivoted near its lower end at 5.4 to 'a bracket 55,'that extends from the forward face of the fixed segment 45. Extending from the rear face of this fixed segment is a bracket 57, to which is pivoted. at 58 another link 59, that is pivoted at its upper end 60 to a bracket 61, which is secured to the rear face of the shift-segment 50. It will thus be seen that the segmental shiftlate 50 is mounted and supported upon parallel links 53 and 59 and is adapted to move onsaid links in a horizontal plane and that unduly this movement of the shift-plate 5O produces radial movements of the levers 43. The link 53 various supportingis extended downwardly beyond its pivot and is rigidly connected to an arm 62, that has its rear end pivoted at 63 to a link 64, which in turn is pivoted at 65 to an arm or lever 66, that is secured to a rock-shaft 67. This rock-shaft 67 likewise has arms 67 X projecting rearwardly therefrom, the rear end of each of which is provided with a depending hook or strap 68, that takes around an actuating or shifting lever 69, which is fulcrumed in the same manneras the character-key levers and is provided with a finger-key 70 at the keyboard of the machine. Each of these arms 67 may be connected-at 71 to a spring 7 2, which has its opposite end secured at 73 to a suitable fixed portion of the machine.

From the foregoing understood that a depression of either key 70 will cause the link or arm 53 to be vibrated on its fixed pivot, thus causing the upper end of the link or arm, together with the segmental shiftlate connected thereto, to be moved towar the front of the machine. This movement of the segmental shift-plate 50 will cause all of the segmentally and radially arranged bell-crank levers 43 to 47 to be vibrated on their common fixed pivotal wire 44, and thereby move the arm 43 of each lever inwardly or radially toward the center of the system, each arm 43 vibrating in the same radial plane that its associated typebar moves in and the rear end of each of the links 33 moving or'swinging with its connected arms 35 and 43. The effect of this radial shifting movement of the arms 43 is to change the position of the pivotal center 42 of each type-bar driver, so that when a character-key is actuated the path of movement followed by the type -bar will be changed, and the upper-case type will be brought to the rinting-point, as indicated in Fig. 3 of the rawings, though each ty ebar will move at all times in the same ra ial plane, whether for upper or lower case printing. In Fig. 3 the dotted line position shows the normal or lower-case printing position of the supporting-lever 43 47, whereas the-shifted or upper-case position is represented in full lines.

From what has been said it will be understood that the type-bar follows one path of movement in printing a lower-case character and follows another path of movement in printing an upper-case character, but that, nevertheless, it always moves in the same radialplane.

Referring to Fig. 2, the lower-case type A description it will belIO is represented as at the printing-point in full point.

and as above the printing position in full lines, and the dotted line connecting the lower-case type inits two extreme positions represents substantially the path of said type when the parts have been shifted to enable the upper-case type to print, and which upper-case type B is shown as at the printing- It will be observed that the path taken by the lower-case type when the parts are in their shifted ositions is different from and longer than the path of said type when the parts are in their non-shifted positions. Simiarly the upper-case type travels through different paths and paths of different lengths when the parts are respectively in normal and shifted positions; but these varying paths of the upper-case type are not shown by dotted lines in order to simplify the views and avoid confusion.

Normally the shift-plate 50 bears against and is stopped by the rear nut 50 but when shifted said plate strikes against and is arrested by the forward nut 50*. These nuts are adjustable on threaded rod 50, which passes freel through the shifter-plate and is supported by bracket 50 attached to the cross-bar 41.

From an inspection of Fig. 4 it will be seen that the various type-bars, drivers, and supports 43 are mounted in planes that radiate substantially from the point indicated by the letter at in said figure and that in the operation of the machine the type-bars and drivers (and which drivers may .be considered as parts of the type-bars) move in'these same planes both when the parts are in the normal position and when in the shifted position. The supports 43, which effect thec range of case, likewise move in the same radial planes in which the typeba'rs move.

From a comparison of Figs. 1 and 4 it will be observed that the point it, heretofore referred to, isin the same horizontal plane with the printing-point and the axis of the platen, as is indicated by the dotted line a in Fig. 1. By reason of the above features of construction I am enabled to make all of the typebars without lateral bends at the type ends of the bars and to arrange the types one behind the other in the planes of the type-bars and with the printing-faces of all of the types at right angles to said planes. Straight typebars or those without lateral bends and wherein every portion of'the type-bar moves in a single plane and those wherein the )rinting-faces of the types are at right angles to vsaid plane throughout the system have many advantages over type-bars having lateral bends where the types are placed and over straight bars where the types are offset or overhang and over type-bars wherein the printing-faces of the types are at angles other than right angles to the plane of movement of the bar which carries said types and are at varying angles throughout the system.

In prior machines it has alwa s been customary, as far as my knowle ge extends, either to bend the outer type ends of the bars more and more as they approach the sides of the segment or circle, where each type-bar is to be provided with a plurality of types, as upper andlower case types, or else to make the type-bars strai ht from end to end and place the u per and lower case types thereon at gradual y-increasing angles, working from the middle of the machine outwardly in both directions or to have the pr ntingfaces of the types at different angles throughout the system relatively to the planes of movement of the type-bars. It results from these constructions last described that the types are oflset from or overhang the major axis of the t pe-bar and not only take up more room in the basket as the sides of the machine are approached, but such type-bars print with a crank-like action and produce faulty and objectionable impressions or that the. faces of the types will strike the platen in a plane other than at right angles to the plane of movement of the type-bar, and a faulty impression will result.

In my construction it will be observed tha t there are no lateral bends in the type-ha rs at any part of the segment and that no one of the types on any of the hers is offset from or overhangs its bar. The types being arranged one behind the other and in the plane of the bar each type will be supported by the body of the bar itself during the impact of the type, and the hitherto offset or crank impressions are thus avoided. The faces of all of the types meeting the platen at right angles to t is planes of movement of the type-bars prevent blurring impressions. Moreover, I am enabled by my construction to provide a greater number of type-bars in a given space than any other machine wherein there are a plurality of types on a bar and wherein the types are offset from the main body of the It will be understood that by reason of the fact that the types are arranged one'behind the other, as explained, and that in the shifting of the parts for upper and lower case printing the parts all move in radial lines, I may providean indefinitenumber of types on each type-bar, adding, of course, the necessary nunfber of shift-keys for the different. number ofshil'ts required-that is to say, each type-bar may have three or more types and may have two or more shil'ts accordingly. Upon reference to Figs. 1 l and 12 it will be seen that each elongated type-holder 74 is pivoted at 75 between the side plates T6 of each type-bar 37 and that each type-holder i 18 provided with an elongated opening 77, 1 through which a pin 78, secured to plates 7c,

extends. Each type-holder has atapering recess at 74: for the reception of a tapering stem 74", which projects from a type-body 74", so that each type-body may be turned, with its stem, to properly position the face of the type on its holder. The pin-and-slot connection between each type-holder and its type-bar adapts'the type-holder to move on its pivot independently of the movement of the type-bar. This independent movement of the type-holder on its bar answers a twofold purpose in the present instance. It enablesthe type to be properly centered in the type-guide in the movement of the type to the printing-point, and it likewise enables the face of the type to be maintained properly positioned on the fixed segmental inking-pad 79, whether the parts be in the normal posi tion to write lower-case characters or be shifted. to write upper-case characters. In other words, the slight movement which is imparted to the various type-bars 37 by an operation of the shift key is ineffective to displace the face of the type from the inkingad by reason of this independent movement of the type-holders and their type bars or carriers. that the invention is not restricted to the use of types which move with relation to their type bars orcarriers and that the case-shifting mechanism may be employed in connection with type-bars wherein the types or their holders are fixed to the bars. Also the invention is not limited to jointed type-bars. While it is one of the ob ects of the invention to produce a front-strike machine in which the types are inked by a pad and print directly on the paper without the interposition of the usual inking-ribbon, nevertheless some features of the invention may be embodied in machines wherein an inkin -ribbon is employed instead of'an inking-pas Situated adjacent to the printing-point is a type-guide 80, whose bracket or support 8O is secured at 81 to a fixed portion of the machine. The support or bracket of this type-guide is bent at 82 to provide a clearance for the upper-case-type holders, elongated stems or supports when the lower-casetype holders or stems are within the guide, as indicated in Fig. 2, and the bracket 80 is secured to the rear portion of the guide in order not to interfere with the type outside of the guide. The type-holders, elongated It should be understood, however,

stems, or type-supports 74 on each type-bar are arranged at such distance'apart as to leave sufficient space between them to permit either type to pass outside the guide when the other type passes through the uide in its movement to t e printing-point, tire walls of the guide being of less thickness than the space between the stems or supports of each The body of this typeuide 80is substantiall cylindrical exteriofly and-is provided with inner guiding-faces 83, that are wider than the arms seaoio adapted to surround the type-body upon all sides. faces, so that the internal opening is rectangular in crosssection to cooperate with four faces'83 (see Figs. 11 and 12) on each typebody to properly guide the type to the print ing-point and to properly center it in the type-guide. The faces 83 are inclined in the usual manner toward the type-opening 84 and are, in effect, angular walls of the guideopening which surround u on all sides the anular sides of the type-b0 y. The upper-leftl iand corner of this type-guide is cut away at 85, and this corner of the guide is preferably beveled on the outside toward the rear thereof, so that the operatorrnayexamine the lastwritten character without moving the platen to either side of the type-guide. it will be un derstood that it is preferable to cut away the upper left-hand corner of the type-guide, hecause of the fact that the opening 85 will thus be-provided at that side of the guide toward which the platen moves in its usual letterspace-feed movement. By reason of the general cylindrical contour of the outer face of the type-guide it enables a free space to be provided at every point around the guide for the type-holders which are not carried to the printing-point during the actuation of the keys, but which must be maintained either above or below the type-guide or to either side thereof when various bars are brought successively to the printing position. Thus when one of the keys at the-center of the key- ,board is actuated to print a lower-case character then the other type and itsholder or stem on the same type-barwill take a position below the guide, as represented in Fig. 2 of the drawings, whereas when one of the-same keys is actuated to print an upper-case character the other type and its holder or stem-on the bar extends above the type-guide, as represented in F i 3 of the drawings It follows that the thic ness of each wall of the guide is such that it will permit the types or their stems to straddle the uide at every pomtthat is to say, the thickness of the walls of the guide is such that they are adapted' toextend between the types, so that one type ona bar may be outside the guide when theother type on the same bar is within the-guide and at the printing-point.

From an examination of Figs. 4, 6, 7, '8, and 9 it will be seen that the pivotal bearing 24* of each lever 24 or thereof. It will also be seen by comparison of these levers in Fig. 4 that the arms of the different levers-connect with the bearings 24* thereof at different points in their widths.

tances apart, though the distances between the arms of the various levers may vary.

Thus upon reference to Fig. 4 it will be seen.

that the arms of the levers 24 and 24* are spaced farthest apart at the center of the segment and the spaces between them gradually decrease as either side of the segment is This facilitates the connection between the various levers and their drivers and lgey-lev erswithout the necessity of providin an irregular mounting of the hangers. It wil likewise be seen that the upright arms of the levers 24 and 24 are arallel throughout the segment, those at the extreme sides being bent inwardly at their upper ends to 1facilitate the connection with their associated .in 's.
