TYPEWRITIN'G MACHINE.

Application filed. September To (all whom it may 0076667 77,

Be it known that l, Greene's GOULD Gems, a citizen of the United States, residing at liliddletown, in the county of Middlesex and State of Connecticut, have invented certain new an d useful Improvements in Typewriting lidachines, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to typewriting machines and more 'mrticularly to type actions therefor.

The main object of the invention, generally stated, is to provide an improved construction and arrangement of parts whereby the elements of each type action are functionally and structurally coordinated to facilitate printing in an improved manner.

More specifically stated, one of the objects of the invention is to provide improved and highly eflicient type actions for printing without producing the noise that ordinarily results from the operation of the type ac tions.

A still further object of the invention is to provide an improved and highly cliicient construction of the character specified in which the type actions are controlled from a standard keyboard with a single shift.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims.

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

Figure 1 is a top plan view of a machine embodying this invention, portions being broken away, more clearly to show the re lationships of the parts;

Figure 2 is a central, fore-and-aft vertical sectional View with parts omitted of a typewriting machine provided with a type action constructed in accordance with my invention, the type action being shown in the normal position;

keys, to print from a type on the lower type block or head;

Figure & is a similar view showing the type-bar printing from a type on the upper type head under an actuation of the other associated printing key; and

Figure 5 is a view similar to Fig. 2 of a modified form of construction.

In the accompanying drawings I have shown only so much of a typewriting 1nachine as is necessary to arrive at an understanding of my invention in its embodiment therein. I have shown my invention applied to a machine which, as to features outside of my invention, may be similar to that formerly known commercially as the Noiseless typewriter.

I provide in the present instance a machine having a standard keyboard of four banks of keys, each type bar carrying four types and being operated by either one of two keys. Each pair of keys actuates a single front strike type bar in a substantially noiseless manner to normally selectively print from one or another lower case type on the type bar, depending on which of the two keys is actuated, or to selectively print from one or another upper case type on the same type bar after a relative case shift has lgeen effected between the platen and type ars.

In the present embodiment of my invention the frame of the machine may be said to include a base and socalled front plate or member on which various working parts of the machine, including the type actions, are supported. It will be understood that the type bars are arranged in a substantially horizontally disposed arc in front of and around the printing point as a center, so that each type bar moves but a short distance in a radial plane to the common printing center. The controlling means for each type bar, with the possible exception in some instances of the key lever therefor, move in the same plane as the plane of movement of the associated type bar or as close to and parallel with such plane as the assembled parts will permit.

With the foregoing general statement I will hereinafter specifically describe a single type action, it being understood that all actions are alike, or substantially so, except that they are mounted in different planes that radiate from the printing center. The description of one type action applies to the others.

Referring now to the drawings, 10 denotes the base of the frame of the typewriting machine which supports a paper carriage (not shown) carrying a platen 11. The machine frame may be said to include a front plate or member 12 supporting preferably a row of brackets or type action hangers 13. Each bracket or hanger has an arm 14 received in a radial slot in the member 12 for adjustably securing the hanger to the front plate by

screws

14 and 14". The front plate is arcuate in shape so that the brackets, carrying the type actions, one oi? which is indicated generally at a, may be disposed in the ordinary man ner about a common printing center. The type action supported by each bracket comprises a type-bar, carrier, or member 15, which is pivotally supported from its bracket 13 by means oi a pair of links 16 and 17. The typebar or member is disposed with its longest dimension arranged substantially horizontally, and is adapted to lie substantially in a vertical radial plane that extends through the printing center. Each type bar is guided in its printing movements in guide slots in fixed upper and lower segmental guide combs Z) and 0 respectively. This member 15, as shown in the present instance, carries four types, the

types

18 and 18 being grouped together and disposed on the lower type head or block, and the types 19 and 19 being disposed on the other or upper type head. The printing tacos of the types on the two type heads are disposed in difierent intersecting planes, for a reason hereinafter more fully explained.

The links 16 and 17 of each type action, while supported on the machine by the as sociated bracket: '3, are not in the present instance directly pivoted to it; the links 16 being pivoted at 20 to the lower arm of the companion bellcrank .lever 21, which is pivoted at 22 to one extremity of the depending arm oi its bracket 13. The second link 17 of the type-bar member is pivoted in the present instance at 25 to one end of a lever 26, which in turn is pivoted at 27 to a supporting member 28 on the associated bracket 13. The upper end of the lever 26 is connected to the upper arm of the corresponding bell-crank lever 21 by the link 30. Each type-bar 15 is thus supported by what I term a quaternal or quaternate linkage having axes of motion respectively at 20 and 25, which axes remain in situ during the movement of the type-bar, except when displaced by the movement of the bell-crank lever 21. A supporting sector 23 having radial grooves in its upper side is fixed in the base of the machine and serves as an additional support for the lower ends of brackets 13, each of said lower ends be ing received in a radial groove in the supporting sector, which enables the c0mpanion bracket to receive its radial adjust ment.

Each type bar 15 is moved from its retracted position, shown in Fig. 2, by a plurality oi? keys through suitable actuating and controlling connections. In the drawings, a pair of levers 31 and are shown as provided with

keys

31 and 32 respectively to actuate the associated type bar 15. The lever 31 is connected through link 33 with a cam lever 34, which has a curved thread where it has rolling contact on one ari'n 35 of a sublever 36 pivoted at 37 to a depending portion of the companion bracket 13. This sublever 36 is adapted to impart a thrust to the type-bar or member 15 through the connected toggle 3839. The link 38 of the toggle is pivoted at 40 to the type-bar, while the other link 39 is pivoted at 41 to its bracket 13, power being applied to the toggle from the sublever 36 through a link 42, which is pivoted at 43 to a depending arm on the link 39. The link 42 has a projecting weighted portion 44, which normally rests on a pad (Z, and which in the operation of the type action is adapted to absorb energy and accumulate momentum from the initial movement of the sublever 36.

The key lever 32 has a pull wire or link connected to apply power to a toggle 51 52, such connection being eflected at a point intermediate the ends of the link 51. The forward end of this link 51 is pivo-tally supported at 53 to another depending portion of the bracket 13. The rear end of the link 52 is pivoted at 54 to apply power to move the bell-crank lever 21. To provide a stop for limiting the breaking oi the toggle 5152, and also to insure proper alignment of the types on the upper head with reference to the printing point on the platen, the link 51 is provided with a heel 55 which contacts with the stop 56 having a cam or eccentric adjustment and located on a depending branch of bracket 13. It also will be understood that this stop 56 limits'the depression of the key lever 32.

The operation of the type action thus far described is as follows:

When the key 31 is depressed. a thrust is imparted to the typebar 15. The key 31 may be depressed until an arm 66 on lever 34 contacts with a pin 67, (in a manner hereinafter explained). which, when disposed as shown in Fig. 3 operates as a stop to limit. the turther depression of this key. During the depression of the key 31 a pull is transmitted through the wire 33 to the cam lever 34, which applies power in the first instance to the tip of the arm 35 ally changing acceleration to the sublever.

Nevertheless, the weight lat absorbs momentum trom the motion of the sublever, and continually stores it through the period oi acceleration, i. e., until the movement of the key lever is arrested. The energy in the weight l-e'l, now accumulated, operates to complete the straightening out of the toggle, and etlects the final movement of the type or character to print; as for instance, the type 18. During this final movement, the arm 35 of the sublever 36 moves out of contact with the cam lever 34. This final position is clearly shown in Fig. 3.

During the movement of the type-bar 15, when actuated by the key 31, the axes of motion 20 and 25 remain in situ. The quaternal linkage supporting the type-bar 15, however, is not shown as, and preferably is not, a parallel linkage. Consequently as it moves, there is motion of rotation of the member of type-bar 15 about an instantaneous center, and a bodily movement or motion of translation thereof, as it moves from the retracted position, shown in Fig. 2, to the printing position shown in Fig. 3. The locus of a point in the typebar, for instance one point on a type, as the bar moves from retracted position to printing position, in consequence is a curvilinear path.

The toggle 38-89, together with the mo mentum accumulator 44, operates as a motion governing means to slow up the final movement of the type bar 15 as it approaches the platen, and translates the energy stored in the weight 1% into pressure during the final movement of the type bar, in the manner fully set forth in United States Letters Patent No. 1,261,751, issued in the name of Anderson. A spring is shown at 63 which is distended by the motion of the sublever during the printing movement of the type bar. The spring operates to retract the sublever, thereby retracting the type bar at the termination of the printing stroke.

We will consider more in detail the curvilinear paths traversed by the types in their movements toward the printing position. VVe will first refer to the lower head carrying the types 1818', and to their movement under the action of the key 32. Such movement of these types is initially upward substantially normal to the face of the head, but the pathway orients until the movement is substantially directly toward the print- .ing position and this orientation. continues throughout that portion of the i'novement which is under the influence of the key 10- ver. When the type bar has reached this point, i. e., the point where the continued motion of the type bar is entirely under the influence of the energy storing member, the tare of one of the lower type 18 or 18' has oriented itself into a position where it is in front of, and coincides with, the platen surface at the point of printing. The type bar 15 then makes a rectilinear advance from this point onward against the platen, i. e., parallel to the radius of the cylindrical platen which is drawn at the printing point. This rectilinear portion of the path of advance of the type bar toward the platen 1s, however, only a very small portion of the total length of the advance; consequently the deceleration of the advance of the type bar 15 toward the platen during its final rectilinear movement is exceedingly quick. This quick deceleration of the type bar, as indicated above, is under the control of the energy storing member, the final execution of the printed character being effected by pressure produced by the final straightening of the toggle 3839 under the influence of the weight or energy storing member 44:.

hen, however, a printing key 32 is depressed, it imparts a pull through the link 50 to the toggle 5152, until the heel 55 contacts with the adjustable stop 56. As the toggle 5152 breaks from a substantially straightdine position, it pulls torward on the lower arm of the bell crank lever 21, imparting a pull. through the link 30 to the upper end of the lever 26, which, as shown in the drawing. displaces the axis of motion 25 simultaneously with the displacement of the axis of motion at 20. The link 16, in its retracted position, shown in Fig. 2, is normally in contact with a pin or other suitable stop 65 on the bell crank lever 21. Power is thus transmitted from the breaking of the toggle 5152 to the link 16 which at this time acts as a lever, as though it were a rigid lever arm extending upwardly from the bell-crank lever 21 to pull the type bar 15. The printing posi tion of the type bar when actuated by the key 32 is clearly shown in Fig. 1-. The continnal displacement of the two axes of motion 20 and 25 under the action of the toggle 515:2 operates to cause the type bar 15 to swing about a continually varying instantaneous center and the proportions ot the linkage of the

levers

21 and 26 are such as to efi'ect at this time a displacement of the type bar 15 to a lower horizontal plane. As a consequence, the type bar 15 executes not only the motion of rotation, but of translation into a lower horizontal plane, until a type on the upper head, as the type 19,- is brought opposite the printing point when absorbed by the n'iotion governing means comprising the toggle ild ilfl and weight 4i, so that the final approach of the type bar to the platen materially slowed up; the printing being etli'ected under pressure by the expenditure oi. the energy stored in weight ll. The t -Jpe bar is retracted, in this instance. not alone under the iniiuence or spring 63. but. also under the influence of tension spring 6i w rich is attached to a heel of each key lener and returns to the normal position. where it is arrested by a suitable stop c.

The path of the moven'ient ot the upper h ad carrying the types 19-19 has in general a curvature which is in opposite direc tion to that oi the path described by the lower heath the types 19 and 19 noving initially in a downward direction, but the path is gradually oriented in a vertical plane but with an angular displacement opposite to that of the normal to the lower beach as the type bar moves forward toward the platen. This orientation continues until the type bar 15 ha, reached the point wl'iere it no longer moves under the impetus or the key lever 32 i. e.. to the point where th energy storing member 4:4: takes tull control of the motion. From this point onward the linal movement of the type bar advances rectilinearly toward the platen, this rectilinear portion of the path of advance of the upper head toward the platen coinciding substantially with the rectilinear portion ot the path of advance for the lower head. Accordingly there is the same quick deceleration in the advance of the type bar when printing from a type on the upper head as when printing from a type on the lower heath this ower nuwement bein citected iy the energy storing member l in both instances. lhe final execution of the printed character from a type on the upper head is thus also produced under influence of pressure due to the final straightening of the toggle 38-39. This curvilinear path and that first described do not diti er solely by the direction of their curvature, but may be, and in the form illustrated are. different s 3130188 of curves. l'his arises primarily because the lever connections to the two keys are ditl erent. As it is desirable to have the touch of the two actuating l:eys alike, it is desirable to so'correlate the el'lective momentum and acceleration of the type bar and connecting elements with the ratios 01 the levers as to present substantially the same resistance at the different keys at corresponding points in the stroke, and to impart the same etlective force to the printing elements at the printing point for the same key movement.

In the form illustrated, each type head menace has two types for printing, each disposed re spectively in ditlerent horizontal planes rela tive to the medial. vertical plane of the typebar 15. If these horizontal planes are drawn at the center of the printing point normal to the faces ot their respective type heads then those of the upper head and those of the lower head are respectively parallel but dis placed by a distance equal to the distance through which the platen is shifted by the case shift. Likewise the parallel planes of the upper head intersect with the 1 arallel planes or the lower head forming dihedral angles which are equal to the dihedral angle formed by the planes of the faces of the two heads. l Vhen the type-bar 15 is actuated selectively by either key 31 or 92 and caused to traverse its respective path, the parallel sets or generally horizontal planes are oriented, but in respectively opposite directions by the two key levers. The set of planes which-"correspond to the characters being printed by one such key however, are oriented in either case to a position of coincidence with the position the. other set would have assumed were the other key depressed.

As will be seen from Fig. 2, the cam lever i-r-l is pivoted at 69 to the bracket 13 and its a depending arm 66 which is adapted to nake contact with the pin or stop 67 on the .ink 5352 when the key 31 is in depressed pon. A stop 68 is provided on the bracket against which the link 51 makes contact n order to stop the toggle 5152 when the aster is in the straight line, or substantially n he straight line, position and thereby n Wm on. H

n event it from breaking beyond such posion in one direction. Should the toggle 1 52 not be entirely straight when the key 01 is depressed, the axes of motion at and would not be in the correct. position for the desired movement of the type bar 15 a ainst the platen. By the provision of arm 66 a final impulse is imparted to the toggle 51--52, whereby it is straightened just prior to the printing of a character from a type on the lower type head of the type bar 15. It is thus seen that the correct position of the axes of motion 20 and is insured at all times when a key 31 is depressed to impart a thrust to the type bar. ll hen a key 32 is depressed to impart a pull tothe type bar, the rigid relation of the link 16 to the sublever 21 insures at all times during this movement of the type-bar that the correct position of the axes of motion 20 and 25 is maintained and that the path of movement of the type-bar will be properly naintained.

in order to insure properly the correct alignment of the types with respect to the printing point, the position of the member M8 on the bracket 13 is preferably made adjustable. lhis member is in the form of a lever pivoted at 70 and having at its forward end an elongated opening 71 which engages with the cam 72 journaled in the bracket 13. The rotation of this cam actuates the lever 28 to adjust initially the correct positions of the axes of motion 20 and 25.

For the purpose of determining which one of either pair of types is to effect the printing, a suitable single case shift mechanism is provided. The machine, as shown, is arranged normally to print from either of the types 18 and 19 which will, as a rule, correspond with the lower case characters, and a case shift is actuated to print from the types 18' and 19, corresponding to the upper case characters, by the shift key. This is accomplished by effecting a relative displacement between the platen and the types. As illustrated, in the present instance, the platen 11 is shifted by means of a lever 73, carrying at its outer end a shift key 74 and pivoted at 75 to the frame. This lever is connected to a case shift frame 76 by a link 77, whereby the depression of the key 74 will cause the platen to move vertically upward relative to the type.

In addition to the operated parts above described, the machine may be provided with ribbon-carrying spools 78 and a cover plate 79.

In the modification shown in Fig. 5, the type action is of a slightly different construction from that previously described. A bracket or hanger 113 has an arm 14 resting and adjustable on the front plate of the machine in substantially the same manner as shown in Fig. 2. The type bar 15 is as before pivotally supported by quaternal linkage. Such linkage includes links 116 and 117 having shiftable axes of motion, respectively, at 120 and 125, supported respectively by levers 121 and 126. The lever 121 is shown as a plain lever arm pivoted at 122 to the bracket or hanger 113 while the lever 126 is of the bell crank type pivoted at 127 to the support 128. This support is made adjustable as before by pivoting it at 129 to the hanger and is controlled and adjusted by the cam 130 working in the slot 131 at its upper end. lVhen the key lever 31 is depressed it pulls down on the pull wire 33, which actuates the sublever 36 to thrust forward the type bar 15, in substantially the same manner as shown in Fig. 2. S hGIL however, the key lever 32 is depressed, it transmits a pull through the pull wire to a link 151 of a toggle 151152. Link 151 is pivoted at 153 to a depending arm of the bracket- 113. This link is also pivotally connected by means of a link 154. to the upstanding arm 155 of the bell crank lever 126 which carries the axis of motion 125. The: depression of the key lever 32 consequently not only breaks the toggle 151152, but actuates the levers 121 and 126. Since by reason of the stop 65, the link 116 moves rigidly with the lever 121 and a full movement is at once transmitted to the type-bar to project it against the platen in a position to print from a type, as 19, on the upper head. The movement of link 151, however, operates to move the bellcrank lever 126, so that both the aXes of motion 120 and 125 are simultaneously displaced. The positive motion thus imparted to the lever 121 operates to guide the front end of the type-bar and at the same time transmits energy to the motion governing means, including the toggle 38-39 and momentum accumulator 4 1, which operates to decelerate the final movement of the typebar toward the platen and effect pressure printing.

By the construction embodying my invention it will be seen that each type-bar is actuated by twokeys 31 and 32*. Each key causes the associated type-bar to move against the platen through a particular individual path, and by so doing selectively prints a character from a type on the upper or lower head, depending on the key which is actuated. Moreover, each type action, except the key lever thereof, for effecting this selective movement of the associated type-bar, is carried as a unit on a single bracket or hanger, and therefore can be removed and replaced and adjusted individually as desired. By properly proportioning the points where power is applied, and the tension on the springs 64, the strokes upon the keys which selectively actuate the type-bars may be equalized throughout the system so that substantially no difference in touch can be observed, while the energy accumulators operate to supply substantially the same pressure while printing from types on the upper or lower type heads.

By the use of this invention, the number of type-bars corresponding to the keys of a so-called standard keyboard may be greatly reduced, or the number of types which may be disposed in a given widthwise space or are is hereby greatly increased, the increase being a direct multiple of the type carrying heads.

By this invention a very compact and efficient machine may be provided. The arcuate length in which the desired types can be disposed is so reduced that the radial distance from the type are to the printing center may be reduced to a length comparatively shorter than it was heretofore practical to use, whereby a quick and quiet action may be provided.

The mounting for the type bars in accord ance with this invention is well adapted for use in conjunction with means for limiting the printing movement of the type-bars and with motion governing means therefor to effeetdeceleration and final pressure printing at the printing point by utilizing the energy initially stored in the motion governing means, and consequently is Well adapted for a type action when it is desired to reduce to a minimum the noise of printing.

The use of this invention in a frontstrike variety of typewriting machine permits ;he disposition of the usually desired number of types in sufiiciently close array about the printing point to have a quick and substantially noiseless type action but yet employ only a single shift.

I am aware that various changes may be made in the construction and that parts thereof may be employed Without others Without departing from my invention as it is defined in the accompanying claims.
