Application led May 21, 1918'. Serial No. 235,812.

To all/whom t may concern: f

Be it known that'I, JOHN H. BARR, citizen of the United States, and resident of the borough -of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Typen-Whiting Machines, of which the following is a specification.

My invention relates to typewriting machines and it has for its object to provide certain improvements in said machines. One ofthe principal objects of the invention is to provide a typewritingmachine that can be collapsed or compacted to make it more convenient for carrying about, and

f that can be extended or expanded to bring vit into position for use.

To the above and other ends my invention consists 1n certain features of construction and combinations and arrangements of parts, all of which will be fully set forth herein and particularly pointed out in the claims. A typ/ewriting machine embodying all the features of my present invention is illustrated in the accompanying drawings in which- Figure 1 is a. side elevation ofthe machine .in expanded position Vready for operation.

Fig. 2 is a front to rear vertical section in expanded position.

Fig. 3 is a perspective view of a portion of the framework which carries the printing mechanism. A

Fig. 4 is a perspective view Aof a part of e the frame which carries the platen and which can be shifted to different case positions.

` Fig. 5 isl a side elevation of the machine in collapsed or compacted position.

.Fig G is a. front to rear vertical sectional view taken just to the right vof the left-hand shift key of the machine and looking toward the left, the machine being in expanded p0- sition.

Fig. 7 is a top plan view of the left-hand half of the machine, in expanded position.

Fig. 8 is a front to rear vertical sectional view of the inachinef'in compacted position.

Fig. 9 is a diagrammatic plan view of the type bar system in its extended or outstanding formation, ready for use. l

Fig. 10 is a similar view but showing the set of type bars in.its flattened or compacted formation. i

The frame which supports most of the means of an angleeiron 11 whose flanges are mechanism of the typewriter will be most readily understood from Fig. 3 which shows a portion of said frame, the remainderbeing broken away. lThe frame comprises right and left-hand end pieces 1 which are connected together at their forward ends by'a double c omb plate 2, which can be secured to the side plates 1 in any suitable'way. As here shown, each of said plates has an 'ear 3 to which the comb plate 2 is secured by a bolt and nut 4; and the side plates also have lugs. or ears 5 which project forward through suitable openings in the comb plate and which may or may ynot be riveted up on their forward ends. The side plates 1 are connected neartheir rear ends by a casting designated generally by the numeral 6 and comprising a type bar mount orn segment 7 'a'nd a sub-lever segment 8', said two segments lying substantially horizontal, the sub-lever segnier1't-in front' of the type bar" segment. Said segments at their ends are integral with a bracket portion 1Q of :the casting which portion is securedl to the side plate 1 'by secured to the lbracket 10 and to the side plate 1 respectively by rivets 12. The end of the bracket 10 does not reach quite to the side plate 1, leaving an opening or slot at the point marked 13 in Fig-3, which serves as a. guide for a movable part of the machine, as will appear hereinafter.` A comb plate 14 extends from right to left across the machine, being secured to the underside of the casting 6 by screws 15 (Fig. 2). This comb plate is bent down at its rear edge and is formed with a series of prongs-or tines 16 leaving slots 17 between them. 'The 'prongs 16 are bent as shown to supporta pivot rod 18. alternate prongs beingbent toward the 95 front and towardfthe rear of the'machine so as partially to embrace said rod and to support it in place. 1` The printing key levers 20 of the machine are pivoted on the rod 18 and are guided'in 100 the slots 17, and near their vforward ends said Y key levers are guided in slots 21, Fig. 3, in the lower part of the comb plate 2. The key levers 20 carry at their forward ends printing keys 22 arranged as shownin the pres- 105 ent instance 'in four rows. Each of saidl key levers is connected by a vertical link 23 in slots 25, Fig. 3, in the upper part of the 110 d.

. the levers 24 screw 4 passes.

comb plate where they are retained in position by bar 2G lying across the upper edge ot said comb plate and'seeured in pesition in any suitable manner, as iior eXample in the manner shown in Fig, 6. Said har as shown provided at eac-h of its ends with an ear 2T that hangs down in iront of the comb plate 2 and through which the holt or Referringto Fig'. 2, for example, each ot 'has pivoted in the forward end thereof a link Q8 which extends upward therefrom and is pivoted to the forward end or" a subdever 30, which is one of aseries of sub-levers pivote-d on a wire 31 in the sublever segment 8. Said segment has the general form of an are oi' a circle and has cut in its upper part a series of radial guide slots 32 tor the. several subrlevers 30 and the wire 3l lies in a suitable slot eut in the forward face of the segment 8 where it is secured by .two screw nuts 33, Fig. 3, one threaded onto eachend ot it.

Each ot the sub-levers 30 hasl gear teeth 34 on its rear end, which mesh with gear teeth 85 on the heel of the corresponding type bar 36. All of the type bars are guided in radial slots 37 in the type bar segment 7 and they are pivoted on a wire 38 lying in a suitable slot 40 cut in the rear face of said segment, and said wire is secured in position by the latheads et two screws 4l screwed Iinto the casting G and the heads of the screws engaging the ends respectively of lthe 1wire. The segment "7 is so shaped that the rear toothed ende` or" the sub-levers 80 also pass through the slots 37 and are guided thereby, and are thus prevented from getting out ot mesh with the gearing on the heels of the type bars.

The disposition and proportions ot the sub-levers 24 will be understood from Fig. 7, where it will be seen that all of the sub` levers 30 terminate in an arc convex to the' trent et the machine and that the links 28 are therefore also disposed in an arc. rThe levers 24 are therefore made of varying lengths, that shown in Fig. Qbeing one of the, shortest and the levers increasing in length toward the right and lett-hand sides of the system. The links 23 which connect Ithe levers 24 with the key-levers 20, are suitably disposed in a front and back direction so that each one of them gives the proper leverage for its key lever on the sublever 30. ils said'sub-levers 30 are all alike they all have the' same extent of oscillation when the keys are depressed.

llach type action 1s provided with a returning spring 42, said springs in the present instance being 'connected to the forward .ends ot the levers 30 and each ot' them con nected also to a hook bent backfrom the forward edge et a plate 44 lwhich plate 6e overlies the sub-levers B0 and is secured by screws 45 to the upper part of the segment 8.

The type bars 36 each carry in the present instance two types 46 and said type bars are adapted to swing rearward and downward and to'strike against the upper tace of a platen 47. The present machine is therefore a top strike machinet Said type barsnormally rest against a pad 48, which, when the machine is eXtended'or expanded ready to be used, stands in the position shown in Fig. 2, Where, in the present ina-- chine, the type bars incline upward and toward the front of the machine. In the pres ent instance these type bars turn through an angle of son'iething like 120O to strike the platen, but this can .be varied; and when the machineI is compacted, they are moved back to a greater angle from the platen, or an angle of nearly 180. When the machine is in its expanded position the set of type bars stand up as shown in Figs. l, 2 and 9; but when the machine is compacted they occupy a low-lying substantially horizontal position, as shown in Figs. 8 and 181, in which position it will be seen they do not project 'above th'e machine, and the machine therefore as a whole takes up less space and can be put into a smaller case than it could if the' type bars stood up as shown in Fig. 1.

The dropping back of the type' bars to the position shown in Figs. 8 andV 10 and their elevation to the position shown in Fig. 2, are preferably effected by moving the pad 48, and in the present instancesaid pad is moved for this purpose down and up. But the raising and lowering of the type bars may be ellected in a variety ot other ways, some or which will be shown in vspeciic applications presently to be filed. The particular mechanism shown for that purpose in the present case will be fully explained hereinafter. Such motion of the type bars is permitted, however, by a peculiarity in the gearing 34, 35 by which said type bars are operatively connected with the sublevers 30. To this end the heel of each type bar hasin front ot and-above its series of gear teeth 35 a smooth circular. convex edge 50 which is adapted to register with a smooth concentric edge portion 51 on the sub-.lever 30 above the gear teeth 34. lVhen the type bar is in its elevated position, shown in Fig. 2, in which position it is ready to be operated, the forward one ot the teeth 35 lies in the interdental space between the uppermost tooth 34 ,and the con-- cave edge 51 of the sub-lever. It the pad 48 be depressed the type bar can drop down to y the position shown in Fig. 8. In the first part of this motion the uppermost tooth 35 will slightly depress the rear end of the subserved by comparing the positions ofsaid ,key levers in the comb plate 2 in Figs. 2 and 8. After thus slightly depressing the rear end of the lever 30, however, the smooth part 5() of the type lbar slides along the con-v cave part 51 of the sub-lever without further operation of said sub-lever, the gear teeth 35 running out of mesh with the gear teeth 34C so that the sub-lever and key are -operatively disconnected from the type bar.

By an inspection of Fig. 8 it will be perceived that when the parts are in the-collapsed position the coperation of the concave 51 and the convex edge 50 will be such as to lock the Vsub-lever 30 and, therefore, the key, against operation. When the type rest 48 is elevated from'the Fig. 8 to the Fig. 2 position the reverse of the above rccited operations takes place. That is to say, the type bar turns independently of the sublever until the first tooth 35 runs into the interdental space just beneath the concave formation of the type bars from" the ex? panded formation shown in Figs. 1 and 2 to the contracted formation shown in Fig, 8. 1n the present instance, however, .I have provided means for still further contracting the machine, and to this end the frame 1,

2, 6, itself is made movable from an extended position to a contracted position, and other parts of the machine also are extensiblel and contractible, as will appear from theA following description.

The type-action-carrying-frame is supported at its forward part by two links 52 and at its rear part by two links 53, Figs. 1 and 5, said links being pivoted to the side plates 1 on pivot screws 54. The links 52 arepivoted attheirrv lower ends at 55 and the links 53 are pivoted attheir lower ends at 56 to a stationary base 57 which is provided with rubber feet 58 on a desk or table.

The base 57 can be of any appropriate form. -As here shown it is approximately in the form of a rectangle andis made of sheet metal `having an upstanding rim G0 and a horizontal flange portion G1, the Whole construction being such that said base is.;

light in weight and yet suiiiciently strong for its purpose. This base can have. any suitable 'side plates attached thereto, such,

designed to rest for example, as is shown at 62 in Figs. 1, -5 and 8. In Figs. 1 :md5 this plate is removed from the side nearest'the observer in order to avoid hiding the mechanism.

The'connection of the links 52, 53 with the base 57 and with the frame 1, 2, 6,.is

such that said frame can be elevated to the position shown in Fig. 1 or be depressedv to the position shown in Fig.l 5, said links rockingl about their pivots in moving from one of these positions to the other. In or lder to retain the frame in its upper position any suitable means can be provided.. that here shown consisting of a pair of flat springs 63 each secured to the flange 61. of thebase 57 by screws 64, and said springs' inclining upward and toward the rear and each terminating in a loop G5, which when the machine is in its, extended position catches under a pin 66l projecting from the link 52. 'These springs hold the frame in its elevated position with a. sufficient degree of security vbut upon the exertion of enough force the tension of the springs can be overcome 4and the frame dropped down to vthe-Fig. 5 position.

When the frame is raised to its upper position, shown in Fig. 1, it is arrested by a lug or ear 67 n the front edge of each of the links 52., saidlugs striking against a slightly projecting end 68 of the comb plate 2.. I Means are provided whereby when the frame 1, 2, etc., is elevated with relation to the base 57 the back stop or cushion 48 for the type bars is at the same time raised still higher so that it not, only partakes ol'l the upward motion of the frame 1, etc.,'but moves upward still farther and .with relation to said frame 1 so as to elevate the type bars to their extended position. This vcan be effected by a variety of means andthe particular means shown in the drawings 1 will nowloe described. Each of the links 52 and 53 has an arm' 70, which arms, when .the parts are in tho Fig. 1 position, extend upward and forward from the pivot screws 54:; and at their upper or forward ends said arms 70 are by pivot screws 71 pivoted to side plates 72, there being one of these plates on each side of the machine, and said plates extending upward from the pivots 71 as shown in Fig. 1, for example, It will be perceived that the location of the pivots 71 with respect to the pivots 55, 58 differ from the location of the pivots 54 in two particulars; that is to say, said pivots 71 are both farther from the pivots 55, 56 and they are alsoin a different direct tion from said pivots than the pivots 5l, so that the motion of the plate 72 is solncwhat different from thc motion of the plate 1. That is to say, the plate 72 moves up and down farther than thc plate 1 and its motion is also somewhat more nearly straight up 'and'downT-it has not lquite so great a component of'motion in the horizon tal directionfas theplate 1."

A topl plate -7 3 -is secured by sc'rews 74 to the upper parts of the two plates 72. From an inspectionof Figs. 2, 7 and 8 it will be perceived-that the rear and middle part ot the said topl plate is depressed below the upper edges of the side plates 1, the line or depression being indicated at 75 in Figs. 2 and This depression forms a sort of semicircular pan in which the type bars lie when the machine is in itsv compacted position as shown in Fig. 8. The type rest 48 consists of a piece of some'suitable material., such, for example, as lfelt or leather, lying in an arc-shaped channel 76 in the rear edge of the top plate 73. rilhe top plate, of course, partakes of the up and down motion of the side plates 72 and as this u and down m'o tion exceeds the up and dbwn motion of the frame 1, 2, etc., in which the type bars are mounted, it will be perceived that in collapsing and extending the machine said type rest L)L8-moves up and vdown relatively to the type bar 'segment 7 and raises the type bars in the one instance to the position shown in Fig. 2 and in the other instance allows them to drop down to the position shown in Fig. 8.

1t will perceived that the machine has at one operation a double expansion and contraction in an up and down direction; that is to say, the whole type action frame is dropped down into the base plate 57 which.V

has the form of a sort of pan and at the same time the type bars drop down into compact relation with the balance of the type action.

It will also be perceived that ,the motion of the parts is such that the machine is expanded andv contracted lengthwise as well as up and down. 1When the machine is in its extended position shown in. Fig. 1, the platen Li7 and the carriage and associated parts stand out some distance behind the rea" edge of the base 57 ,but when the machine is contracted to the Fig. 5 position these parts come ins/ide of said base. This fore-and'aft contraction of the machine is, of course, due to the swinging of the upper ends of the links 52, 53, not only downward but also toward the front of the machine. Said links, whenin expanded position, stand approximately vertical, whereas, when in compacted position, they lie toward the 'front of the machine, more nearly horizontal. lVhen the machine is in itsscompacted l position, it can be expanded by the operator grasping the projecting edges of the top plate 73 andraising said top plate to its expanded position. All of the other parts, including the type bars, automatically assume .their expanded positions also, at the same time, so that the machine can be brought into condition foi-.use by this single motion.

rpart of theleveriwhichfbending, however,

Leccese By comparing somewhat similar to that of the other parts;

that is to say, in compacting the machine said space bar has ,moved forward and downward, but it has not moved as far forward as the printing keys 22. It will also be perceived that this peculiarity of the motion of the space bar has the effect of a contraction of the machine in a front and rear direction. Such motion is brought about by the peculiar mounting of said space bar which is here shown as a bar of any suitable material secured by screws 78, Fig. 1, to the front cross -bar 8O of a yoke-shaped'frame, which comprises side bars or lever arms 81, one at the right-hand andi-the other at the left-hand side of the machine, said levers 81 vbeir1, 2,tpivoted at their rear ends on pivot nearer to the front of the machine than the v pivot 54. When the machine is in its extended positionv ready for use, these screws 82 serve as suitable fulcrums for the space frame, but when `the machine is compacted the pivot screws 82, by reason of their peculiar relation to the pivots 56 obviously do not move as far toward the front of the machine as the screws 5/1 and this accounts for the space bar havinga forward motion less than thatof the printing keys 22.

In order to pivot the spacing levers 81 to the links 53 in the manner described it has been found convenient in the present instance tQ make these-levers of a peculiar form. It will be noted in Fig. 7 that the orwardend of the lever Sl there shown lies to the right of the vshift key lever and it will be noted from Fig. 1 that therear end of the lever 81 there shown, this being the right-hand one, however, is pivoted to the outside of the link 53; and it will be perceived that this involves olf-setting the rear part of each lever 81 from the front 'part'. This olf-setting is effected chiefly by cutting Y out the lever 81 in the iirst place of a form that will be understood from the -following description and making two bends in it, the front' part of the lever and the rear part being connected by a hor'igontal dat part 83, Figs land 7, this Hatpar't of the lever underlying the shift key lever. The odsetting is addedto by a slight bending of the rear rails 86. Standards 87 rise from the bed 84 it has not been thought necessary to show in the present drawing. The levers 81 of the space bar are provided with any suitable restoringsprings 79 (Fig 2).

The carria e 84 of the machine can be of any suitable 'nd as far as my present in- Vention is concerned. As here shown it comprises a bed-part bent atits front and rear edges to form two ball-bearing rails 85 which face two relatively stationary .grooved of the carriage and support the platen 47.

lS-aid carriage and platen may be equipped The rails'86 -are mounted on horizontalbrackets or arms 93 from one of which the bracket 92 projects, said rails being fastened to the brackets 93 by screws which pass through holes 94, Fig. 4. Said Fig. 4 shows ythe left-.hand one of the two side pieces which together with the rails 86`constitute the main part of the shift frame. Each of' said side pieces consists of avertical plate 95 made of sheet metal and having the.

bracket 93 bent 0E from the rear lower edge thereof.

The verticalv part of the plate 95 lies against the inside face of the side plate 1 of the type action frame, a portion of the straight upper edge thereof lying in the slot 13, Fig. 3, between the end of the casting 6 and the side plate 1, which slot therefore serves in part as a guide for the shift frame. The plate 95 is supported in the manner shown in Fig. 6. Said plate is prolonged toward the f'ont of the machine as shown in Fig. 4 and at its forward end has a pivot pin 96 projecting therefrom, which pin is pivoted in the lower end of an arm 97 fixed on a transverse rock shaft 98 extending across the front of the type bar frame, said shaft being pivoted to said frame on a pivot screw 100, Fig. 7, screwed through a hole 101, Fig. 3, in an upstanding ear' of the side plate 1. As this rock shaft extends across the machine and is connected with the plates 95 on both sides ofthe machine it insures that the two ends of the shift frame shall move front and back to the same extent.

Each of the plates 95 is, nearits rear end, pivoted at 102 to the lower end of a link 103 which is pivoted at 104 to the side plate 1. the links 103 being substantially parallel to the arms 97, so that the shift frame has subpart of the type action frame in the act of extending and contracting the machine.

The shift key 105 and its connections are shown in Figs. 6--and 7. Said key is mounted on theforward end of va key lever 106 which at its rear end is pivoted on the same rod or lwire 18 as the printing key levers.

A link 107 is connected at its lower end to. the key lever 106 and at its upper end said link is pivoted at 108 to abell crank 110 which is.v pivoted.` 'on a pivot screw 111 screwed into an ear 112 ofthe side plate 1. The bell crank 110 is folded upon itself so as to take a bearing on the screw 111 at two points spaced apart, and theY depending arm .of said bell crank has a slot 113 in which plays a pin 114 on the left-hand side piece 95 of the shift frame. The constructionK` is such that when thekey 105 is depressed said Shift frame is pushed toward the rear of the machine. Said shift frame is normally held in its forward position by means of a returning spring 115 which is connected at its forward end with the bell crank 110 and at its rear end to the link103.

The stops for limit-ing the front and rear movements of the shift .frame consist of pins,

116 projecting eccentrically from the ends of screws1 117 threaded through the side plates 1 and having outside of said side plates lock nuts 118, Fig. 1. An upstanding lug 120 onthe side piece 95 on each side of the machine, is adapted to play between a pair 0f the stop pins 116, said lug being arrested by said pins. It will be perceived that the precise position of each pin 116 can be regulated by giving a part turn to its screw117 and seposition by curing the screw in its adjusted tightening the lock nut 118.

The carriage escapement mechanism in-` cluding the universal bar is carried by the shift frame and consequently these parts move up and down when the machine is eX'- tended or compactedand they also shift iio front andl back when the platen is shifted.

A feedrack 121 is mounted onthe carriage 84 by means of brackets 122`secured to said I upper rear parts of the side plates95 ofthe y shift frame. 'The arm 125 is one arm of an angled lever having another arm projecting forward from the Shaft 126 and havisc ing a pin 131 at its free end, said pin projecting ,into a hole 132 in an arm 133 whichis' fixed tothe shaft 126 near the ymiddle of the machine. 'The hole 132 is larger than the pin 131 so asto provide lost motion between th'e shaft 126 and the arms 130 and 125,`whereby the extent of oscillation of the arm is less than that of the shaft 126.

Said shaft 126 is operatedthrough the v138 extending toward the front of the machine from the pivot 137 and a universal bar is mounted on the forward ends of the two levers 138. Each of the levers 138 has a bracket or ear 139 bent olf therefrom a little forward of the pivot 137 and said brackets underlie the space key levers 81 as best shown yin Fig.v 1. As these two levers are pivoted onvv the shift frame it will be seen that 'they move front and back with said shift frame. rI'he universal bar is here shown as a round rod suitably mounted on the free ends ofthe levers 138 and lying,r be! neath ,lugs 14,11 formed on the lower sides of the printing'y key levers 20, said lugs being of siich.length that they overlie the universal bar in both of its case shift positions. Restoring springs 142 for the universal bar are-here lshown as plate springs secured at their rear ends .to the bracket 93 of the shift frame and at their forward ends underlying the arms 138.

The ribbonsy spools and their-,driving toward the middleof the machine from the rear part of the upper edge of the shifting plate 95 and said brackethas a hole 144 therein in which is' mounted the stud 145, Fig. 7, of the ribbon spool 146 this same construction being. of course, duplicated on the two sides of the machine. As bestshown in Fig. 4 the inner end of the bracket 143 is bent up to form an ear 147 having .a notch 148 therein in which notch is journaled one end of a drive shaft 150 having thereon at each end thereof a bei/ e1 pinion 151 adapted to mesh with a bevel or crown gear 152 secured to the lower flange 0f the ribbon spool 146. ln the machine represented in the drawings, means are provided for shifting the shaft 15() endwise to cause it to drive the right or lefthand spool as required. Said means is not shown in 'versal bar.

headset saidmechanism is mounted. l The shaft 150 can be dgivenin any suitable way. 1t 1s here shown equipped with v a ratchet wheel Y153 which can be operated by any suitabie pawl mechanism from the shaft 126 which, it will be recalled,vis operated by The machinecan be provided with any suitable form of lribbon vibrator, that here :shown comprising a plate or bar 154 of sheet metal lying beneath a rigid bracket 155 projecting rearward at an upward in clination and secured at its forward end by a screw156 to the rear face of the type bar segment 7 at vthe middle of the machine. rhis bracket 155 has ears 157 at its forward end serving as a center guide for the type the uni-- i bars. The ribbon vibrator bar 154 has ears 158 overlapping the bar or type guide 155 and it also has ears 160, Fig. 7, projecting from one side thereof, one in front of and the other behind the upper end ofthe lever arm 133 which is mounted onl the universal rock shaft 126. The vibrator bar 154 has 4any suitable loops or ribbon guides 1.31m 1t will be perceived that' the vibrator is moved back and forth with the Astrokes'lof the printing keys after the usual fashion of such devices. and that it-partakes ofthe entire rocking motion ofthe shaft 126 of which the feed dogs 124 partake of only a part, dueY to the lost motion connection 131, 132. lt will also be understood that the ribbon vi*- brator slides along thebar 155 when the case shift, key is operated.

The drawings show a bail-shaped frame lor bracket 162 secured at its lower end to the under side of one of the rails 83, and lying just in front of the platen 47; This bail or bracket has certain paperrontrob recognized that this change in the formation of the set of type bars is a thing distinct from the movement of the set of type bars as a wholedue to the movement up and down of the type bar segment or common support 7 Various changes can be made in the details of construction and arrangement without departing from my invention.
