Application filed June 15, 1914. Serial No. 845,207.

i To all whom it may concern Be it known that; we, JOHN H. BARR and EDWIN E. Banner, citizens of the United States, and residents, respectively, of the aborough of Manhattan, city of New York,

in the county of New York and State of New York, and Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which at-ing mechanism thereof, which includes,

and the operation of which depends on, the: whole typebar-system, the object of the invention, generally stated, being to better the construction and operation of the typeactions and mechanismactuated by them, especially in single .shift-machinesin which the segment instead of the platen shifts. The invention' consists of mechanism embodied in a front-stroke typewriting machine, at"

cluding the features of construction, combinations, and arrangement ofparts hereinafter described and specified in the'claims.

In the accompanyingdrawings, in which like reference numerals designate like parts in differentviews, and which illustrate portions of a front-stroke typewriting machine containing the invention,

Figure 1 is a central, vertical, longitudinal section, and side elevation, of the frame and some of the mechanism of the machine;

Fig. 2, a vertical cross section, on the plane indicated by the line .1, .1, Fig. 1, of the frame and some of the mechanism, a front elevation of parts both in front of and behind that plane, and a diagrammatic illustration of some parts; Fig. 3, a vertical cross section and rear elevation of portions of the frame and mechanism, the section being on planes indicated by the lines y, y, Fig. 1;

and Fig. 4, an enlarged perspective of a device called a pusher.

The frame of the machine'is composed of five castings, 1, 2, 3, t and 5, the last being the top-plate. Each of the castings 1 and 2 forms a side of the base and includes two of the posts 6 by which the top-plate is supported and to-which it is affixed. The sides of the base andthe castings 3 and 4, which are respectively the front and rear portions of the base, are fastened together with tap-bolts, four of these, 7, beingshown in Fig. 1. The fixed plate .8, in the rear part4 of the base, forms the fulcrum of the typekey-levers 9 and the two levers 10 of the space-bar 11. The levers 10 have downwardly extending ears 10 and are connected together by'a cross-rod 12 affixed to these ears, and are provided with restoring-springs'12. All of these levers extend through slots in the comb 13 fixed in the part 3 of the base. The typekey-levers 9 are connected by links 14 with a set of angular levers, mounted dn a fixed support above the key-levers, each lever 9 having on. it a hook 15 and each link being forked at its lower end and engaged with a hook, which passes through the fork and over a pivot-pin fast at its ends in the branches of the fork. A fiat springlfi, riveted to the lever and extending close to the back of the link, normally keeps the latter engaged with the book but allows it easily to be disengg 'ed therefrom. -These angular levers, '1, are punched from thin, fiat stock and are all alike, each having a rearwardly extending arm 18 and an upwardly extending arm 19, and the links 11 are connected to the arms 18. The support 20 of the levers 17 is made from sheet-metal, and has the form shown by Figs. 1 and 2. The levers 17 are pivoted on horizontal axes in hangers 21 which project from the back of the support and have fiat stems 22 which extend through holes in the support and are upset on its front face (Fig. 2). The support is attached by-screws 23 to lugs 21 formed on the top plate, and is connected by the bar 25 with the part 3 of the frame.

The tvpebar-segment 2G and typebar-rest 27 are firmly fastened together by means of the two side-rods 28 and the central bar 29, and are supported on the two arms 30. near the sides, and' the links. or double link 31, about midway between the sides, of the machine. The arms 30 are fast on the-shaft and are pivotally connected at their front ends by the pin 37 .to the arms 33 of a bracket having the top 39 through which extends the stud 10 that is fast in the lug 41, formed on and projecting from the back of the segment. -This stud also passes through the bail-shaped bar 42, and this bar and the top 39 of the bracket just descr bed are clamped together and firmly but ad u stably attached to the stud by nuts 43 which engage with screw-threads onthe stud. A spacing-sleeve which fits closely between the links 31 is shown surrounding the pin 37. The arms 30 are parallel and equal in length and their pivotal axes are parallel to and equally distant from the plane which contains the pivotal axes of the links 31, the length of which may equal, or be somewhat less or greater than, that of the arms 3O.

Between the links 31 is a frame formed from a piece of sheet-metal and having the back (H, and the sides e15 which are connected together by the pin 46 on which is the roller 47. This frame is attached to the links 31 by the bolts or, screws 48 and 49 which extend through thelinks, and through the slots 50 and 51 in the sides of the frame, and on which are spacing-sleeves 52, closely fitting between the sides 15. The roller may be raised and lowered by loosening the bolt 48 and turning the frame on the bolt 49, and may be moved forward-and backward by loosening the bolt 49 and turning the frame on the other bolt, and th erefore is properly adjustable with relation to the cam 53 having the slot 54'throug-h which the roller extends. This cam is fast on the shaft 55, which is a; rock-shaft, connected at its' ends to the sides of the frame, and on which, near its ends, are the arms 56, connected by the links 57 with the shiftkey-levers'58, fastened to the shaft 59, which is also a rockshaft, connected at its ends to the sides of the frame. The bar 42 is attached near the sides of the machine to the vertical rods 60, which are fast at their upper ends in the lugs 61 on the back of the segment and pass through the bar, which is adjustably fastened on the rods by nuts 62, and the parts 63 of this bar-extend under "the blocks 6%, cast on the sides of the frame, and on each of these parts are pads 65. The coil-spring 66, attached at its upper end to the screw 67, extending through and below the top plate, and at itslower end to the spacing sleeve on the bolt 48, normally keeps the links 31, arms 30, segment," typebar-rest and bar 42, in the positions in which they are shown, and then the'pads 65 on the upper sides of the parts 63 of the bar 42 are in contact with the blocks 64. The blocks .68, which are cast on the machine-frame directly under the blocks 64, and the screws (l /(Hid which project from the tops of these blocks, support the plates 71 and enable them to be adjusted with relation to the parts 63 of the bar 42. The screws 69 pass through these plates and the screws 70 are normally tightly set against the under sides of the plates. W'hen lower-case writing is done the Segment and type-rest are in the positions in which they are shown, and when they areshifted to enable uppercase characters to be written, the operation of a' shift-key rocks the cam 53, and the front ends of the links 31 are pulled down untill the downward movement of the bar 42, and

of the segmentand type-rest is arrested by the stop-plates 71. .By this operation the coil-spring 66 is stretched, and when the shift-key is released thisspring raises the segment and type-rest. to their normal positions, their upward movement being ar-. rested by the stopblocks64 and bar t2.

The type-bars are pivoted to hangers attached to the front face of the segment 26, on which they are arranged in twocurved rows, one eontainingthe hangers 72 and the other the hangers 73 of the type- bars 74 and 75 respectivelyf which normally lie near their front ends on the pad 76 that forms part of the typebar-rest.

In construction and arrangement the type bars and hangers do not .difl'er materially from those of well known Remington machines. That part of the typebar-rest which is behind the pad7-6 is much like a slotted typebar-segment in form, and in the slots 77 thereof levers 78 are mountedon a common curved pivot-wire 7.9, the upper or inner arms of these levers extending close to the convex side of'the type'bar-system and b ing connected with the'type-bars by links 80,

and the lower or outer arms of the levers 78 being connected by links 81 with thearms 19 of the angular levers 17' above described. The median plane of each lever 78 is at right angles to the pivotal axis of the type-bar to which the lever is connected, and preferably coincides wvith the median -plane of that type-bar, so that the median planes of the levers of thisset diverge as they recede from the convex side of the typebaysystem, and the elevations of these levers increase in order from the middle to the-ends of the set.

The coil-springs 82, connected to the lower or outer arms of the lovers 78, and to the hooks 83, formed on the plate 84, attached to the front ofthe typebar-rest, are tensionsprings which normally compel the levers to push on the links 80 and pull on the linksBl of these springs, and Wlien'a type-key is acso that the type-bars cannot rebound even slightly unless they overcome the resistancetuated there is no lost motion at any of the joints between the key-lever and the lever 78 on which the key-lever acts. The springs 82 will restore the typekey-levers,type-bars and a the other parts of the type-actions to their normal positions, during the operation of the machine. When a type-bar is operated the upper or inner end of the lever 78 then actuated moves into the space normall ra pied. by the type-bar, the mnstruction scribed enabling the lever so to act wiQh out interference from any of the other type bars, and the force that ora -rates the type bar is confined to a single plan:- from ti front end of the link 81 to the pivot. of he type-bar. The lines a in Fig. 2 indicate dia grammatically the pivotal axes of several type-bars, and the lines e) 2) indicate planes which are the median planes of those type-bars and of the levers TS coi'inectctl thereto. and in which the forces act that arrtransmitted from those le ers to the type hars through the conneeting links. Th:- links 61 are so arranged that when the set: inent is in its shifted posiiion they are in clined to the vertical planecontaining th pivots of the levers 17 substantially to the same extent, but in a ditl'erent direction. as the are when the segment is in its normal position. and this.arrangen'n-nt of the linlr S1. and. the action on them oi the springs and levers 78 as above les-"ril erl. prevent. or help to prevent. the shifting: operation from producing a vibration sum as is called \\'ink" in either the tv t'lT l.l-S \'l-;ltn1 or tin; kewboard. for the swing; of these links or their rear pivots. and the slight movement of the levers T8 on the front pivots of the links. there being! lost-motion to he taken up in these joints. will not disturb the levers l? or affect the relations of the levers Th to the typebarwest, links 80. t \*pe.-l'.-ars and seen'lent.

The number of these levers equals that of the type-liars. and the med wt planes of the levers coincide with those of the t vpe-l ars. the elevations of the li"\' l'7-- n;- ereasing in order from the middle to the co lof the set. and to these levers at their lower ends are connected the coil-springs 88. which are also connected to the hooks 89 and tend to force the upper or inner ends of the levers forward. these hooks being formed on th plate 9), which is fast on the segment.

mally engages, the clutch and pinion being also mounted on the bracket 127. The arm 130, fast on the shaft 110, is connected by the rod or link 131 with the cross-rod 12, through which the rod 131 loosely passes, and on the rod 131 under the cross-rod 12 are the nuts 132, the upper nut being normally in contact with the cross-rod, or nearly so.

The operation of the levers 87, through the action of the type-bars on the pnshers 95, as described, causes these levers so to rock on the universal bar 102 that this bar is pushed backward at each stroke of a type-key by the actuated lever 87, the bar swinging on the upright arms 106, 107 and 108, and slightly turning the rock shafts 109 and 110, and as the bar 102 moves backward the dogrocker 123 is rocked by the action on it of the rod 122 and nut 125. The springs 119 and the dogroc ker-spring (not shown) re store the universal bar, rod 122, and dogrocker to their normal positions. The levers 87 rock on the universal bar 102 from about midway between its curved edges to or nearly to its upper or inner edge, when the segment is in its normal position, but when the segment is shifted to its lower position the levers 87 descend so that in the operation of the machine in writing uppercase characters these levers act on the universal bar from near its lower or outer edge to about midway between its curved edges. The depression of the space-key rocks the shafts 109 and 110 so that the universal bar 102 and rod 122 move backward and the dogrocker is rocked as above described.

In consequence of the practice of the at ent ()tiice concerning the division of applicacations, parts of the mechanism above described, which are believed to be novel and patentable, are not claimed herein, but the right to claim those parts in another application is not waived.

It will be understood that the invention claimed below may be embodied in mechanism differing more or less in details of construction and arrangement of parts from that in which it is illustrated herein. \Ve are not aware that a shifting set of type-- ba arranged in two curved rows, and mechanism comprising a universal bar and a (onnection between it and the escapemcnt, have heretofore been combined. so that, both when the typebarsupport or segment is in its normal position. and when it is in its shifted position, the universal bar will be properly actuated by the type-bars, and by the force of blows struck by them, and by portions thereof that are remote from the type-blocks. where they travel much less rapidly than do portions near the type-blocks.

The shape and location of the universal bar, and the means through which the action of this bar is made to depend on blows struck by the type-bars, are the result of numerous inventive acts and experiments by which the mechanism described herein was developed, and that mechanism illustrates the invention in its preferred form.
