HERBERT E. BRIDGWATER, OF DERBY, CONNECTICUT, ASSIGNOR, BY MESNE ASSIGN- MENTS, T0 SECOR TYPEWRITER COMPANY, OF DERBY, CONNECTICUT, A CORPORA- TION OF CONNECTICUT.

TYPE-WRITING MACHINE.

To all whom it may concern.

Be it known that I, HERBERT EDMUNDS BRIDGWATER, a citizen of the United States, residing at Derby, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

My invention relates to certain improvements in that class of typewriting machines known as front-strike machines and more particularly to the construction in such machines of those portions comprising the adjustable fulcrum support and segmental guiding of the type-bars.

In typewriting machines of the class referred to, the full complement of type-bars is generally restricted within a segmental curved or arch-shaped support, the angular extent of which is less than half a circle. The subdivisions of this angle by the usual number of type-bar bearings arranged side by side, in substantially a circular arc with its center at or near the printing point, brings the typebar heels or pivotal ends close together, confining within narrow limits any device for providing type-bars so arranged with adjustable fulcrum support and radially guiding means. On this account, it has been customary to employ an integral segment of the desired radius, and by means of saws cut closely adjoining radial slots for the reception of the typebars as guiding means, and then to provide an annular groove intersecting these slots in which a curved rod is held as a fulcrum common to all the bars, but which provides no independent or individual adjustment of the type-bars. The subdivisions of the segment between the slots are connected only at one end to their support and it is not unusual for these divisions to warp or spring, altering the dimensions of the adjoining slots and thus make the fitting of the typebars therein an expensive operation. Also, the removal of a type-bar from such a segment is not readily accomplished, necessitating as it does the withdrawal of the fulcrum rod from out adjoining bars on one side, unless the bar is simply suspended on that rod by an open hook, the use of which is objectionable. In this class of construction where no independent adjustment of Specification of Letters Patent. F

the bars is possible it becomes necessary to distort the bar between the type-faces and fulcrum bearing to efiect changes in dimensions within the bar for alining operations.

The object of my invention is first: to provide a segmental guide-support for a set of type-bars which is preferably integral in character and of such form as to avoid the springing of its radial subdivisions by the operation of slotting by forming the part to be slotted so as to provide a slot of ample guiding capacity and at the same time require the removal of a comparatively small amount of metal and leave the radial subdivisions in integral connection preferably at both ends with the segment; secondly to provide a movable hanger or individual fulcrum support for each type-bar individually having its point of attachment on an abutment disposed in such a plane as will permit of an independent adjustment of each type-bar fulcrum point radially in a line toward or from the writing point without disturbing any of the other bars in their several individual adjustments.

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

I have shown my invention in the present instance in its application to a frontstrike machine, though it should be understood that the construction therein disclosed may be varied without departing from my device as claimed and may be readily employed on various styles of typewriting machines.

In the drawings, in which similar reference characters indicate corresponding parts in all the views, I have shown only so much of a typewriting machine as is necessary for the illustration of my invention.

Figure 1 shows the front elevation of the carriage and segment supporting bridge of the typewriter. Fig. 2 shows a sectional view of Fig. 1 at X, X to which is added the side elevation of a key-lever and its connections to a type-bar which is here disclosed in printing position. Fig. 3 is a fragmental portion of Fig. 2 showing the greater portion of a type-bar in normal position. Fig. 1 is an underneath plan view of the bridge and segment of Fig. 1. Fig. 5 is a fragmentary enlarged view of the rear elevation of the segment comprising that sectional portion forward of the line Y, Y, Fig. 2. Fig. 6 is a planview of one of the individual hangers with its type-bar journal end and an associated type-bar in section on line Z, Z, Fig. 3. Fig. 7 is a view showing a plane development of the segment on right line A, A of Fig. 2, and the intersecting arc line B, B of Fig. 1, showing the arrangement of the type-bars in their relative normal position. Fig. 8 shows the side elevation of a type-bar head in printing position in connection with a modified form of type-bar guide. Fig. 9 shows a front elevation of the type-bar guide illustrated in Fig. 8. Fig. 10 shows a sectional view of a modified form of my type-bar segment. Fig. 11 shows a sectional view of a further modification in the form of my type-bar segment. Fig. 12 shows a sectional view of a form of my type-bar segment in which the guide member is divided, and Fig. 13 shows a sectional view of a modification of my type-bar segment adapted for use in rear-pull front-strike typewriters.

The frame of the machine (not shown) supports a bridge 1 shown in Fig. 1 in front elevation. The upper edge of this bridge is grooved as a guide way for the running support of the carriage, a portion of which is shown at 3, Fig. 1. This carriage supports the platen 4-. for longitudinal axial movement across the machine during the writing operation. This bridge is shown in section in Fig. 2 with the platen 4; in the position which it is carried above the bridge. From the front of this bridge 1 projects the segmental port-ion 5 which, as is shown in Figs. 1 and 4., has its axis in the center of the machine and at a point just below the writing-point at 6. It opens upwardly as a segment toward the upper edge of the bridge 1 and is in vertical relation to the front side of the platen a. This portion of the bridge 1 will hereafter be referred to as the typebar segment. This type-bar segment is preferably cast solid as one piece with the bridge 1 on which it forms, as viewed from the front, an annular flange, but being cored out in the casting as a hollow member it forms, as viewed from the rear, a segmental recess 7, see Fig. 3. The axis of this segmental recess is at all points uniform from the axial point 6. The arch-formed wall of this segmental recess is slotted radially as shown in Fig. 1 to a depth or extent shown in Figs. 2 and 3, to provide the guide mem bers 8 with the slots 9 for reception of the type-bars.

In thus slotting this type-bar segment it is converted into a series of arches or arch-like divisions with their faces in parallel radial alinement with the faces of adjoining arches, each archlike division being attached at its extreme ends to the bridge 1. of which it forms an integral part and which effectively maintains them in fixed relative position. The arch-like form or outline of the divisions of the segment in their upper portion between the axis of the type-bars and the printing point, extend tangentially to where they unite with the main body of the segment as is seen from Figs. 2 and 3. By employing the described construction, I secure a type-bar heel guide bearing of relatively large effective proportions by the removal of a comparatively small amount of metal during the slotting operation, while the intervening divisions are securely held against warping, springing or other displacement which would impair the dimensions of the adjoining slots. The type-bars 10 are pivotally fulcrumed on individual hangers 11 which are attached to and supported by the annular abutment 12 which is disposed in a plane parallel with the axis of the recess 7 which it adjoins as a part of the bridge 1. The hangers 11 are fixedly attached to the segmental abutment 12 by the screws 13. The hangers 11 are shown in detail in Figs. 2, 3, 5 and 6. They are preferably in the general form of a right angle comprising a bearing arm and an attaching arm. Each of these arms is flattened, one is slotted as at 13 for the reception of its attaching screw so as to permit of adjustment in a direction parallel to its axis, and laterally under the head of the screw. The other arm is thinned to dimensions less than one half of the axial distance between the type-bars at their fulcrum ends in their position in the segment and carries a boss or pivot stud 14, on one side of its extreme end, the length of which is equal to the thickness of a type-bar at its journal.

end. The slotted arms of these hangers rest upon the abutment 12 in such position as to allow the bearing arms to project forwardly into the recess 7 bringing the axis of the bearings 14- generally concentric with the arched wall of the hollow type-bar segment. The type-bars 10 are fulcrumed on the studs or bearings 14 in this position as shown in Fig. 2. To mount or insert a type-bar, a hanger 11 is loosened by slacking its attaching screw 13 and then swung thereon to one side against an adjoining type-bar heel (if present) thereby carrying its pivot stud 14 out of line wit-h the slot to which it is opposite, as clearly shown in the right hand hanger in Fig. 5. The type-bar to be mounted or inserted has its heel end entered through the slot thus cleared by the swinging aside of the hanger and the fulcrum hole therein is adjusted to find the stud on said hanger. The hanger is then swung to position engaging the stud 1 1 in the fulcrum hole 15 as shown in Fig. 6. The walls of the slot 9 provide a lateral support for the type-bar in its oscillations on the bearing 14, while permit-ting of any necessary movement of the bar in its plane of oscillation that may be due to a movement of the hanger 11 in a similar plane. By an inspection of Figs. 1 and 2, a typebar 10 is shown in printing position with a typeguide pin 16 engaging a typebar guide 17, which consists of a hardened bushing mounted in the plate 17 which is attached to the bridge 1 by the screws 17 in such position that the guide 17 coincides with the axis of the radial slots 9 shown at 6, Fig. 1. Each type-bar carries a pin 16 to which the position of the type 18 is previously gaged in its attachment to the bar. A type-bar is engaged with a loosened hanger as described and is then brought to the position as shown in Fig. 2 with its pin in the type-bar guide, then the screw 13 of the hanger 11 is tightened which secures the hanger and bar in the proper radial adjustment to bring the pin 16 into engagement with the guide 17 at each printing 0perat-ion. To remove a type-bar it is only necessary to loosen its hanger screw 13, swing the hanger to one side as previously described, when the bar may be withdrawn from its slot without disturbing any of the adjoining bars.

Ordinarily the type-bars at their heel porticn will be of such dimensions in thickness as to fill the slots with a running fit, so that stud 14 will serve only as a fulcrum for the type-bar in its oscillations thereon. If as the result of long continued use, the bars and slots become worn so that in effect the slot becomes too wide to guide the bar steadily, it will only be necessary to carry the bearing arm of the hanger 11 toward the bar in a line parallel with the axis of its bearing until the type-bar heel is embraced between the opposing wall of the slot and the face of the bearing arm portion of the hanger, securing the hanger in this position as before by its screw 13. Thus the type-bar will again with certainty bring its alining pin into engagement with the typebar guide at its printing operations.

The printing operation is performed by depressing the key-lever 19 fulcrumed on the bar 20 supported in the main frame of the machine. The key-lever 19 is operated by the finger-key 21 and its movement is transmitted to the type-bar 10 at a point 22- on its short arm 23 by the stirrup-link 24, the bell-crank 25 and the draw-bar 26. The type end of the bar 10, when in normal position, as shown in Fig. 3, rests on the pad 27, Fig. 2. Retracting springs 28 and 29 are provided for the return of the several parts to their normal position after each writing operation.

In Figs. 8 and 9, I show a modified formthe type 18, this extension entering and cooperating with the type-bar guide. The heel portion of these type-bars would be the same as hereinbefore described. hen a type-bar guide of this form is employed in connection with my improved segment and hanger, the types 18 are attached to the bars 10 in as uniform relation as possible to their fulcrum points. Final and close adjustment of the types in relation to the writing line can then be readily efiected by the radially movable hangers 11 by means of which any typebar may be shifted radially endwise toward or from the writing point independently of the type-bar segment in order to cause it to bring its type to the proper position in its printing operation.

In Fig. 7 is shown a sectional plan view of my type-bar segment in which the are E, B of Fig. 1 is projected as a right line. Type-bars 10 are shown in plan view here in the normal posit-ion as shown in Fig. 3, mounted upon their hangers 11 in attachment with abutment 12. For the purpose of this illustration three groups of a part of the bars are shown, the types 18 being omitted from one of the groups as being duplicates only of the opposite group on which the type 18 are displayed. On these type bars are shown the type-guide pins 16 which are shown in Figs. 1 and 2 as entering the type-bar guide 17 as the point at which all the type-bars intersect at the extreme end of their radial length. Beyond this point the bars extend in a direction at an angle to the plane of oscillation of the bar in a direction which, when the type-bar is in printing position, is cross-wise of the platen or at right angles to the line of writing. The extent of this angular bend, which takes place at the axis 'of the guide pin 16, increases from the center of the segment to its ends, near which ends the angle is so great as to materially reduce the space between the types 18 when in their normal position. The effect of this condition would be to cause the type to collide or restrict the width of the characters that may be used on them. To obviate this effect, I carry the fulcrum bearings of a number of bars at each end of the platen gradually increasing distances rearwardly in a line parallel with the radial slots 9 and at right angles to the abutment 12, to such an extent as to provide ample working room for the type 18 when in their normal position. This I accomplish, as shown in Fig. 7, by successively shortening the bearing arms of the hangers 11, which are near the ends of the segment, so that the axes of their fulcrum ournals are in oif set axial relation and progressively closer to the plane of the abutment 12. This I am enabled to do very readily in connection with my integral type-bar segment on account of the individual hangers that I employ as a part of my device, by reason of the independent character of the hanger which carries the typebar as a fulcrum support therefor in line with its guiding slot in the integral segment.

The type-bars herein referred to are prefcrably of equal length, although my invention is not limited thereto, also the features of integral construction particularly alluded to in the preceding specification may be modified without departing from my invention.

In Figs. 10 to 13 inclusive, I have shown modified forms of the slot-ted segmental recess, the slotted faces of which form the radial guiding surfaces of large extent for the type-bar heels. In Fig. 10 the form of segmental recess is generally arch-shaped or circular in cross section but open on its upper side toward the front of the segment.

In Fig. 11 another modified form is shown in which the segmental recess is also generally arch-shaped in cross section but is open at the lower portion toward the front of the segment and the arch is of somewhat less extent than that form shown in Fig. 10.

In Fig. 12- the slotted segmental recess is shown as open toward the front of the machine thus presenting in cross section separate slots or slot faces 9 on opposite sides of the pivot stud.

In Fig. 13 the slotted segmental recess is angular in cross section presenting an angular slot face or radial guide for the type-bars.

In all of the modifications of the form of slotted recess shown in the drawings, the same principle of providing a radial guiding slot having a large guiding capacity or surface is exhibited, the form of recess in cross section being such that the type-bar is guided in all of its positions or points of travel from its position of rest as indicated in Figs. 3 and 10 to 13 inclusive, to its printing position indicated in Fig. 2; so that the type-bars are constantly guided through the full extent of their movement.

By the construction shown and described I have provided a segmental pivotal support and radial guide for the type-bars of typewriting machines, particularly of the style referred to and known as the frontstrike or visible Writing machine, in which the bars are provided with ample lateral or radial guidlng surfaces and with individually and independently adjustable pivot supports or bearings, and in which a full set of type bars are mounted side by side in a single series. By reason of the extended lateral guiding surfaces provided in combination with the small lateral extent or space occupied by each bar, I am enabled to accommodate a full set of bars in a single segmental arrangement or series and at the same time provide against lateral deflection of the bars in all positions in their paths of movement.

It will be understood that the precise details of the invention shown and described, may be varied by those skilled in the art without departing from the invention or sacrificing the principle or advantages thereof.
