Specification of Iietters Patent.

Application filed April 3, 1915. Serial No. 18,987.

To allwhom it may concern:

' Be it known that we,'CHARLEs J. Bonn 1 and HUBBARD N. J OSLEYN, citizens of the United States, and residents of Syracuse. in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which thefollowing is a specification.

Our present invention relates primarily to the universal bar mechanism of typewriting machines and its main object is to provide new and improved mechanism of the character specified.

To the above and other, ends which will hereinafter appear, our invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

"In the accompanying drawings which illustrate the prefer-red form of our invention, applied to a typewrit'ing machine having some characteristics of the Monarch typewriter, Figure 1 is a front to rear vertical sectional view of said typewriting machine,v Fig. 2 is a fragmentary detail view on a larger scale, said-view being partly in side elevation and partly in section and showing features of the universal bar construction. Fig. 3 is a horizontal sectional view taken on a plane indicated by the dotv at. said line.

tedline a: in Fig. 1 and looking downward.

F ig. 4 is a top plan view, partly in section,'

showing various parts as they appear when the top plate is removed. Fig. 5 is a vertical transyerse sectional view taken on a plane indicated by the dotted line g z in Fig. 1 and looking in the direction of the arrow Fig. 6 is a rear elevation, partly in section, showing certain of the escapement devices. Fig. 7 is a fragmentary perspective view showing the novel uni- "versal ba'r mechanism and associate parts.

As shown in the drawings, the main frame of the machine comprises a base 1, posts 2 Rising from the top plate are standards 4 to which are fixed upper and lower grooved rails or track-ways 5 and 6, said. rails coiperating through antifriction balls 7 with the rear bar or slide 8 of a carriage or platen carrier. Said carriage further comprises forwardly extending end bars 9 rigid with the bar 8 and prov viding bearings for a rotary platen 10. Co-

,and the outer type 14 or the one farthest from the pivot of the type bar being an upper case type, thu reversing the usual order of the types in the Monarch machine. The

' type bars are preferably pivoted on a common pivot wire 15 which is mounted on a shlftable type bar segment 16. The type bar construction and mounting are not herein described in detail as they are the joint invention of Hubbard N. Josleyn and John W. Koerner and form the subject-matter of their application. Serial No. 19,470, filed April 6, 1915. Each type bar is connected by a link 17 with an upright sub-lever 18 which is fulcrumed at 19 on a key lever 20, said sub-lever being slotted at 21 near its lower end to cooperate with a fixed abutment 22. The set of key levers 20 are fulcruined on av plate 23 mounted in the rear portion of the base and each key lever is provided with a key cap or button 24.

Near their outer end portions the type bars are normally supported by a curved 'seg'mental rest 25 which is mounted on a frame 26 screwed to bars or rods 27 rigid with and projecting forward from the segment 16 near each'side thereof. Said segment 16 and said rest 25 are comprised in a type bar support which is shiftable at will tochange case. The segment ,16 is provided at its sides with upright track members 28 which cooperate through anti-friction. balls 29 with oppositely grooved trackways 30 secured to osts 31' fixed to and rising from the base 1. The sets of balls 29 at the sides of the segment are each controlled by a separator 32.

For limiting up and down movements of the stopping end of each of the devices 35 and 36 into tongues 39 and 40. The tongues .39 with which the stops mounted on the segment coiiperate directly, are, because of this construction, somewhat yielding or resilient so that both the noise and the jarring incident to the arrest of the segment at the end of shifting movements are minimized. The body portions of the devices 35 and 36 are provided with elongated slots ,41 which receive headed screws 42 by which each stop device isadjustably secured to the rear face of the post 31. The stopping face of each tongue 39 is inclined to correspond with the inclined stopping face of the associate stop on the segment, the construction being such that by moving the .stop device in or out prior to setting it by the screw 42, the point of arrest of the segment may be varied. Thestop devices 35 and 36 are not claimed herein as they are the invention of' George- A. Seib and form in part the subject-matter of his application Sr. No. 69,601, filed December 31, 1915.

Tosupport the segment and shift it downand up, devices are provided which are con. nected to lugs 43 extending downwardfrom the segment, one near each end thereof. Said devices comprise a pair of upright links or bars 44, the upper ends of which.

are .pivotally connected by screws 45ito the outer facesof thelugs 43. The lower ends of said links are pivotally connected by screws 46 to the free ends of rearwardly extending crank arms 47, said'crank arms being provided with hub portions 48 which fit over and are fixed to a rock shaft 49 bearing at its ends on pivot screws 50-secured in th sides of the base 1. Segment shifting and locking devices are provided which are the sole invention of Charles J. Bond and are disclosed and claimed in his'application' Serial No. 22,032, filed April 17, 1915.

- Said devices comprise short forwardly extending crank arms 51 arranged near the ends of the rock shaft 49 and provided with hubs 52 which fit over and are pinned or otherwise secured to the rock shaft 49. Just inside each crank arm 51 a curved arm 53 is arranged, said arm being provided with a slot 54 which receives a headed screw 55 that is threaded into the contiguous'arm 51, .the' arms .53 and 51 being thus adjustably secured together and so that the relation of the arm 53'with the rock shaft 49 may be I varied. Said arm 53 is cut .outto fit over said rock shaft and take a bearing thereon,

thence curving upward, rearward and d0w.n

ward, its rear end carrying a pivot screw 56 on which is mounted a roller 57. Operative on the lefthand roller 57 are lugs 58 and 59 projecting downward respectively .from shiftv key levers 60- and 61. These levers are fulcrumed at their rear e ids on Iagpivot-screw ,62 which-is supported in a U-- shaped bracket 63 that is suitably secured to the under face of the rear portion of the basal. This bracket has a slotted guiding ear 64 by which the levers 60 and 61 are guided. 'Each lever is provided with a coiled restoring spring 65 and the lever 60 has a key button 66 while the lever 61 has a 1 kev button 67. A right-hand shift key lever 68 corresponding with the shift key lever 61 at the left is provided, the lever 68 hearing on apivot screw 69 supported by a fixed bracket 7 0, which bracket is provided with aslotted guide ear 71. The lever 68-has a restoring spring 72 and a key button (not shown). The depression of the key 66 shifts the segment and causes it to be locked in shifted position, while the levers 68 and 61 control the temporary shift of the segment anddo not lock'it down. The shift locking devices comprise a latch 73 pivoted at 7 4 to the lever 60 and constructed so that when the key 66 is operated the upper end of the latch is thrown under a fixed abutment 75 by a spring 76 connected to the lower end of said latch 73 andto the lever 60 The latchis released by apin ,77 on the lever 61 which throws the upper end of the latch rearward from under the locking abutment 75 when the key 67 is operated. Normally the segment 16 is maintained-in its upper position with the movable stops 34 engaged with the lower stops 36 as illustrated in Figs. 1 and 5, in which position the inner or lower case .types 13 are operative. For thus normally maintaining the segment inupper position, spring means are provided. comprising a pair of draw springs 78 each connected .at its forward end to a pin 79 extending radially downward from the rock shaft 49. The-rear ends of the springs 78 are adjustably anchored to screw hooks 80 threaded respectively into projecting ends of the screw pivots 62 and 69 and .adjustably set by locking nuts 80 Suppose the shift'key lever 61 is depressed, thenits lug 59 will act on the-roller 57, de-

pressing said roller and turningthe rock however, the lever 60 is operated the .seg-' ment willbe locked down in upper case position by. thelatching or looking devices.

To guide the type bars during printing operations, a type guide is provided which 'is supported on 'a' ,segmentalplate .81 ariac vMonarch typewriting machine.

ranged above the type bar pivots and having cars 82 whichreceive screws 83 by which the plate is fixed at its ends to lugs 84 on the segment 16. Asegmental abutment 85 on the front face of the plate 81 is struck by the. type'bars at or near the ends of their printing movements. The plate 81 has a depression 86 as shown in Fig. 3 and in said depression is. seated aplate 87 which is fixed in place by screws 88. The plate has a central opening 89, the lower portion of which is shaped to provide a pointer 90 which cooperates with the platen scale (not shown). A type opening or slot 91 at the upper end'of said plate '87 is adapted to receive't-he types and guide them to the printing point. Ateither side of the type opening' horizontal wings or guides 92 project forward from the plate .87 which guides are shaped to provide a flaring mouth'communieating with the slot 91. The

devices

91 and 92 guide the type bars near their free ends during printing while near their pivot ends the type bars are guided by slots 93 in the segment 16 inwhich they are seated. The plates 81 and 87 cooperate to provide a guide and support for the stem 94: of a ribbon v1- brator or guide 95 Which comprises in addition to the stem both a head composed of parallel branches 96 diverging from the stem and also guide fingers 97. The COIIlblIlGd type guide and ribbon guide device 87 shifts with the support 81 and the type bar segment 16. Through the ribbon vibrator 95 is threaded a ribbon 98 which is preferably carried by spools (not shown), said spools being rotatable and controllable by suitable mechanism preferably like that found in the The stem 94, as shown in Fig. 3, is slidably supported and guided in a way made by depressing the rea'r face of the plate 87 as indicated at 99,-

this depression, togetherwith the front face of the plate 81, providing a grooved track fer-the stem 9-4. The rear face of the plate 87 is further formed with a vertical depression or slot 100 which registers with a slot or opening 101 out in the plate 81. The vibrator is actuated by means which cooperate with a pin 102 supported at the rear of the stem by a plate 103, riveted or otherwise secured to the rear face of the stem 91 and terminating at its lower ends in cars 101 which are curled around and clasp the ends of the pin 102. Engageable with this pin. 102 is the forward slotted end of an operating lever 105 which is fulcrumed at 106 on a lug 107 depending from the top plate. The rear arm of the lever 105 is slotted, as indicated at 108, and receives an actuating pin 109 that projects laterally from. the top of a link 110, the lower end.

whi -e01? is pivotally connected at 111 to a universal bar frame 112 which isoperative by the key levers to pull down the link and operate the lever 105 and the ribbon vibrator. During the vibratory movements the forward end of the operating lever moves up and down in the slot 100, 101. The position of the actuating pin 109 in the slot 108 may be varied to vary the extent of throw of the vibrator, this variation being effected by means'which comprise a rotary member 113 which is mounted on a ribbon driving shaft 114 and which coiiperates with the link 1'10 Toguide the link, devices are provided comprising a slotted guide 115 secured to a comb plate 116 which guides the sub-levers 18.

The universal bar frame 112 comprises a straight universal bar proper 117 underlying the key levers, said bar being secured to curved crank arms 118 which project rearward from a rock shaft 119 having fixed pivots. The pivot 111 is on the middle one of said crank arms of which there are three. Pivoted at 120 to the middle arm is a lever 121 having a pin and slot or lost motionconnection 122,123 with said middle arm. The forward arm of said lever terminates in a lip 121 which is engaged by a device (not shown) operative from the space bar of the machine. The universal bar construction here described resembles generally that disclosed in the patent to Barney No. 893,422, dated July 14, 1908. The explanation of the operation of the universal bar mechanism heretofore described Will be deferred until after the description of a supplementary or additional universal bar mechanism which is operative directly by the type bars.

adjustable two-part link 125 with a dog rocker 126 pivoted at 127 to cars 128 on a stationary bracket 129. The horizontally disposed arm of the rocker is provided with a screw stop 130 having a leather buffer or end portion 131 which is normally maintained engaged with the bottom face of the bracket 129 by; a rocker spring 132. A second screw stop 133 carried by the upright arm of the rocker is provided with a leather buffer 131 which cooperates with the rear portion of the bracket 129 to limit operative movements of the rocker. The buffers 131 and13i lessenconsiderably the noise due to the arresting of the rocker at the ends of its movements. The rocker carries at its upperend two dogs and 130 which cooperate with a toothed escapemcnt wheel 137, said 'escapement wheel being operatively con-' The rear arm of the-lever 121 is connected by an saidrocker and thereby lessen the noise-due to such-impact, Theoperative connection between the escapernent wheel 137 and the shaft 138 comprises a spring-pressed pawl 14L} pivotally mounted on a housing 142 fixed;- shaft'138 in the'usual way Said pawl .cog'iperates .with a ratchet wheel 143 i id with ihejescapement wheel, 137. Acircularspring'guide-or cam 144 loosely surrounds said ratchet wheel and in the space betweenits ends and the pawl 41 normally passes and is held in engagement with the ratchet wheel 143 by the pawl spring :141 and the pull of the main spring. v During letter space advance'movements the guide 144 will be, carried'around with'the pawl 141 and the ratchet wheel 143 so that its relation will not bezchanged. The guide spring 144 hasenonghgrip on the ratchet wheel to-re' main stationary long enough to enable the left-handfree endof the spring to cam or,

noiselessly over the teeth of the ratchet wheel 143 and maintaining the pawl tooth disengaged from said ratchet teeth, thus avoid} the noise which has heretofore re-v sill ted re n the backward clicking of the pawl ever the ratchet wheel during carriage return movements. The construction involving-..the spring 144 is per sethe sole invehtion, of Hubbard N. Josleyn and is disclosed and claimed in his application, Sr. No." 35,837, filed June 28, 1915. The for-. wardend of the shaft 138 carries a feed 'pinionf145 which is normally engaged by a feed 'rack l46 mounted on the earriage'S, 9.

Said carriage is normally urged leftward .by a: motor or springdrum 147 to-which it is connected by a strap 148.,

T ,he spring drum 147 is connected with .thefribbon driving shaft 114 in the usual.

yway' found in the Monarch machine, the

go-connection com-prisingaratchet wheel 149 .-mounted-"at the front face of sald spring drum, and also beveled pinions 149 and 149 ,the first rigid with said ratchet wheel and the second mountedon and driving the shaft 114; j.-In stead, however, of the/usual pawl for connecting said ratchet wheel 149 with said spring drum at times when the spring drumturns' to draw the carriage in printing-direction, a spring 150 of novel constructionis secured to the ratchet pawl by a screw 151 and engages at its free end with the ratchet. The spring and pjawl construction per se is the sole invention of Hubbard N. Josleyn and is the subject-mat ternqf .hisjapplication, S r.- No. 35,838, filed June 23, 1915. During the returnmovemerits of the carriage, and spring drum the "spring 150 willslide lightly over the ratchet teeth and the clicking sound which results in the ordinary construction from the movement of the .pawl over the ratchet teeth is in the present instance largely eliminated.

Supplementary universal bar mechanism is provided comprising-a curved universal bar proper 152 arranged just below the plate 81 and between the same and the pivot portions, of thetype bars.- Said universal bar-152 is of light stock and is in the form of ase'gment concentric with the segmentally arranged set of type bars. The front edge of the universal bar'is turned inward to provide. a contact surface 153, which is in a vertical plane normally forward of theplane of the plate 81,.as is clearly shown in Fig. 1. The contact surface or flange which also lends rigidity to the universal bar'is engageableby faces or projections .11 on the type bars 11 by which the universal bar 152 is adapted to be moved bodily rearward in both shift positions of the-type bar segment. To this end the universal bar 152 is supported from the plate 81 so that said bar may shift with the type bars and their.

support. Thenormal or lower case position of the universal bar is shown by full lines in .Fig. 2 while its abnormal or upper case-position is indicated by the dotted lines in said figure. In the present instance the universal bar 152 is slidably carried by devices comprising a supporting frame composedof 218136111 154 from which diverge

branches

155 and 156, said branches being connected at their ends by a cross portion 157. This cross portion is provided with a depression or-open top notch 157 (Figs. 4, 5 and 7) to allow for the up and down movements of the operating lever 105. .The inner face of the universal bar 152 is prefer ably'lined witha layer of-felt 158, which felt is cut away to permit two ears 159 in which'the branches and cross portion of the supporting frame terminate to contact di-' rectly with the universal bar. proper 152, the latter being suitably secured near its ends to the care 159 as by riveting. At about the junction of each of the

branches

155 and 156 with 'the cross'portion 157 a horizontally arranged and forwardly projecting pin 160 is suitably fixed to the sup- 9 I 120 porting frame, the pins bearing slidably in transyerse-holes 161 in theplate 81. The rear end of the stem 154 is turned up at one side, as indicated at 162, providing an angle portion in which is received and suitably secured ablock 163perfor'ated as in dicated at 164 to bear. on a guiding and su'pporting red 165 said rod extending horizoa'itally and beingfiXed at its forward end in the late. 81. Secured in therear end of said rod is a stop screw-1 66 which, through contact of the .block 163 with the head of said screw, limits the rearward movements. of the universal bar de ice comprising the universal bar 15:? and its supporting frame. Normally the universal bar device is held in forward position by a coiled spring 167 anchored at its forward end to the plate 81 and connected at its rear end to the universal bar frame. It will be understood that the universal bar device is slidably supported on the plate 81 which is rigid with the type bar support, said universal bar device having three triangularly arranged sliding points of support, two at the front where the pins 160 bear in the openings 161 and the other at the rear where the block 163 bears on the rod 165. [This con struction provides for an easy fore and aft movement of the universal bar device under'the actuation of each and all of the type bars and in both lower and upper case positions. v 1 I 'Theuniversal bar frame is connected to the dog rocker 126 by devices comprising an upright lever 168 of the first order which is fulcrumed at 169 to an angularbracket 17 fixed to the rear of the plate 81. The lower arm of the lever 168 is connected by a link 171 to -an angular bracket 172 fixedto and depending from the cross portion 157.. A horizontally disposed link 173 connects the upper arm of the lever 168 with anangular bracket 174 secured by a screw 175 'to the upper arm of the dog rocker 126. The link 173 may be readily detached from its pivotal points of connection with the lever 168 and the bracket. or arm 174. It will be understood that when the universal bar 152 is operated by any one of the type bars it will move bodily rearward, this movement being transmitted through the link 171 to the lever 168, the lower arm of which will swing rearward and the upper arm forward, -the latter arm pulling forwardthe link .173, with the result that the dog rocker will be actuated; It will also be understood that the connections between the dog rocker and the universal bar 152 shift or move when the type bar segment and said universal bar are shifted, the lever 168 and link 171 shifting bodily and the link 173 swinging or shifting about its connection with the bracket 1741 on the dog rocker as a center, there being sufiicient lost motion in 5 the parts to permit of these movements.

The universal bar 117 as stated is operated by one part of the type actions, viz., the key levers, and actuates both the escapement devices and the ribbon vibrating de 60 vices. The universal bar 152 is operateddirectly bythetype bars, that is, by another part of the type actions, and actuates only the escapement devices, having no effect on the ribbon vibrating devices which are inde- '65 pendent of said universal bar 152. The two the movement of the latter. In the present instance during the initial portion of the key depression. the universal bar 117 is effectively operated, actuating the dog rocker and the ribbon vibrating devices in the usual way. During this portion of the stroke .of the type bar the universal bar 152 moves idly, receiving. actuation through the con nections between it and the dog rocker comprislngthe link 173 and lever 168. When the type bar reaches the point in its movement toward the platen indicated by the dotted line of said type bar will pick up the universal position in Fig. 1, the portion 11 bar 152 which, through the described train of connections, will act effectively on the dog' rocker to swing the same forward, taking it out of the control of the universal bar 117. In other words, the key lever through the universal bar 117 starts the escapement in motion and the type bar through the uniyersal bar 152 finishes or completes the movement of the escapement. The important result accomplished by this construction is that a practical uniform let-off of the escapement is insured through actuating the escapement from the type bars while at the sametime the usual objections to actuating the escapement on this principle are done away with. By employing two universal bars and effecting the initial movement of the escapement devices through the key lever operated universal bar, the type bar is relieved of the retarding effect which would result from striking. the universal bar 152 when at rest orin its normal position, and which would be unavoidable if the universal bar 152 alone were employed.

It will be observed that by our present invention we provide in combination With carriage and escapement devices, two cooperative universal bars for actuating said devices, said universal bars being actuated by means controlled by a single key, sa1d means in-the present case comprising 'a type action consisting of a type bar, a key lever and connections between said type bar and key lever; that separate trains of devices connect the universal bars with the dog I means for beginning a movement" of the es- I capement devices while the other, or curved, universalv bar operates the means for completing the movement; that the mechanism is so timed. that one universal bar initiatestn operation, ccessively actuated; that both universal bars are constantly connected t5 the escapement devices through the described trains of connections to the dog rocker; that each key lever directly operates one universal bar and indirectly through its connected type bar operates the other universal bar; that one of the universal bars, in the present instance the type bar actuated universal bar, is associated with means for initiating movement of said universal bar prior to its actuation. by a type bar; that certainof the escapement devices the operation 0nd univcr comprising the dog rocker and the dogs mounted thereon are given an initial movement in one direction by one universal bar,

movement in the same direction being completed through and by the other universal bar independently of the first universal bar; that one universal bar actuates both escapement devices and also ribbon vibrating devices, and the other universal bar operates only one of said sets of devices, in the present instance the escapement devices; that there are provided a platen element and a type bar element relatively shiftable to change case in combination with a universal bar shittable automatically when the case shifting operation takes place and a second universal bar that does not shift but has an unvarying normal position, this last named universal bar being mounted on a stationary part of the machine, while the other universal bar is mounted on one of said elements, in the present case, on the type bar clement, segment or shiftable support; and that the shiftable universal bar is connected with a nonshittable dog carrier or rocker through connections comprising an intermediate lever and two links, said connections shifting with the shiftable universal bar and the segment or type bar supporting element.

Various changes may be made without departing from our invention.
