To all whom t may' concern: y

Be. it known that I, CHARLES PHILO MosHER, a citizen of the United States, and

a resident of Groton, county of Tompkins,

' and State of New York, have invented cer-y` tain'new and useful y vlVritmg Machines,

Improvements in vTypeof which the following is a full, clear, and exact description.

This invention relates ,more particularly to the ribbon mechanism of foldable 'Visible or front-strike typewriting machines in which the keys of the keyboard may be brought into close relation to the platen to make the machine compact when not in use, andl is a division of my application Serial No. 56,242, filed October 16th, 1915.

One of the principal objects of the invention is to provide a typewriting machine in which a universal or standard keyboard may be employed and in which the ribbon mechanism may be operated by the keys of /the keyboard and the entire keyboard and key action folded with respect to the platen and l keyboard having individual keys for operating individual type and whereinpthe pivotal part of the foldable support may serve as a connecting means between the keys and the ribbon mechanism for the platen carriage in order that no break or disconnection is necessary whether the machine is in a folded position or in an'unfolded position.

A further object of the invention is to provide a simple and efficient mechanism. for vibrating a ribbon to cover and uncover the printing point and for imparting a step-bystep lengthwise movement to the ribbon.

A still further object of the invention is efficient connecting means between the ribbon mechanismvand the keys of the keyboard ofa foldable typewriter. y

A still further object" of the invention is to provide the ribbon a typewriting machine in which. mechanism and the parts operaty ing ythe same are of simple construction and may bereadily made and assembled.

.lVith these and other objects in view, the invention will be hereinafter more particularly described, with reference to the accompanying drawings, which form a part of this application, and will then be pointed out in the claims at the end of thedescription.

In the drawings, Figure 1 is alongitudinal section of one form of machine embody.v

Fig. 6 is a vertical sectionytaken on t'e line 'VI-VI of Fig. 2 of a part of the ribribbon lengthwise transversely of the n1achine. i

l While the invention shown as applied to a typewriter in which an inclosing case is employed, it will be understood that the folding principle between the key-operated levers and the ribbon mechanism may be embodied in a machine in which an ordinary o'r any preferred rform of frame may be employed or a frame independent of such case, and. that said foldable principle as .well as the construction of the ribben viral operating means therefor may be employed in typewriters of various constructions.

The casing has a main member 11 and a top member or cover 12 which 1s hlnged at 13 to said main member 11.. At the forward lower edge of the main member 11 is a foldable member 14 which is pivoted or hinged at 15 to said main member 1l so that said member 14 may be folded upwardly and when so folded and the cover 12 thereon moved over and forward as shown in Fig. 3, a substantially uniform and regular inclosing case is provided. This member 14 may be held in its open position by means of stays 16 or any other suitable means, and said stays may be slotted as at 17 to engage headed pins or studs 18. The stays are normally forced in one direction by springs 19 and the slots 17 are curved orso arranged that in one position the stays will act as a lock, and when forced against the springs 19 the case member 14 may be moved to its folded position. I

A foldable support or member 20 is pivotally held to atransversely extending rod 21 which is supported in the sides of the main casing member 11 or in sleeves which serve as the direct bearing for the support 20 and at its forward end said folda'ble support 2O may be connected by links 22 to the member 14 so that the member or mipport 20 may be folded with the member 14 of the case. The support 20 has sides 23 which may be connected by a transverse bar 24 and mounted in said .support 20 is a segment 25. r1` ,fpe-bars 26 are pivoted to the segment in any suitable way, as to a rod 27, and said type-bars are adapted to carry a'plurality of type and be supported at their outer ends on a cushion 28, the latter being held to a cushion supporting' frame 29 extending out wardly from and supported by the segment. IThe type-bars are each normally forced in one direction by springs 30and are each connected by a link 31 to one arm of a bellcrank lever 32. Each bell-crank lever is pivotally held to a rod or support 33. Y There are four rods each being adaptedto support a plurality of the levers 32. The bellcrank levers 32 each have one arm, as 34, provided with a cam edge 34a which is adapted to engage a cam edge 35 of key-operated levers 36. These key-operated levers 36 are supported in groups or banks upon rods or supports A37 which are horizontally arranged in the normal operative position of the machine under the rods 33 and correspond in number to said rods 33. As each key is depressed the cam edge 35 will operate @U its coperating bell-crank lever and through a link 31 will move the type bar upwardly and rearward for printing purposes, and by reason of the arrangement in groups or banks a substantially uniform touch is obtained.

Laeaaoe ranged in the raceways to adapt the bed and carriage to travel easily transversely of the machine. The carriage may have end plates '44 in which is mounted to rotate the usual platen or roll 45. The carriage may have the usual paper apron 46 'and the usual linger knobs 47 for rotating the platen. and

may also be provided with the usual or any preferred form of line-spacing means, paper fingers and other attachments usually em-` ployed in typewriting-machines, but as such features form no part of the present invention it is thought unnecessary to describe or show them in detail.

To vibrate the ribbon and to move the same lengthwise of the platen in a foldable typewriting machine it is necessary that provision be made whereby the folding principle involved will permit the operation of such ribbon mechanism by the depression of the keys during the printing operation. As onev means, I provide a universal bar 48 which is suspended by arms 49, the latter being pivotally held at 50 onthe type-bar segment 25, there being any suitable number of arms 49 or other supports for the bar 48.

The universal bar 48 is adapted to be engaged by the rear cam edge 51 of the typebars 26. The purpose of the cam edge 51 of the type-bars is to start the universal bary gradually during the upward and rearward movement of the bars and to give the universal bar an accelerated movement without altering the uniform characterof the touch of the keys and in order that no sudden jar on the keys may be apparent to the operator when the type-bars start to actuate said universal bar. At the rear of the universal bar are upwardly extending arms 52. These arms rest idly at their upper ends against the rear surface of the universalv bar 48, and at their lower ends are held to a transversely extending rod 53, the latter being pivotally held at its endsin the sides of the support 20. Arms 54 project forwardly from the rod 53 and said arms `have their forward ends slotted to engage pins 55 carried by the inner ends of arms 56. The arms 56 are held to the transyersely extending pivot rod 21 and serve,

when the universal bar moves the arms 52,

' which one end of the rod 2 1 passes, said cam member 58 being normally forced inwardly by means of a spring 61. The slid'- ing canrmember 58 is provided withan annular Igroove which is engaged by the forked end 62 of a llever` 63.

pivoted at 64 to a lug on one of the sides of the main casing member 11 and has its upper arm 65 extending inwardly and pro- Y vided with a slotted or forked end 66 which described, the said rod is adapted to engage a pin 67 extending outward from a rod 68, so that on each movement of the lever 63 as will be presently 68 by means of the pin 67 will be rocked.- on its pivot pins or screws located 'at't "e ends thereof.

The rod or shait'68 serves as the direct operating or connecting means for the vibrating mechanism for the ribbon to move the latter to cover and uncover the printing point, and as ameans whereb may be operated to give the rlbbon a stepby-step movement lengthwise in the direction of movement of the platen, the ribbon mechanism if desired being constructed to adapt the ribbon to have a plurality of fields or zones of different colors, or to remain inactive forstenciling purposes. As shown, the rod or shaft 68 has an arm 69 projecting outward therefrom which is connected to one end of a link 70. The link 70 is connected to .an outwardly extending arm 71 which is pivoted at 72 to a bracket 7 the latter having downwardly extending arms secured to the plate 41 forming a part of the carriagetrack. The arm 7l forms a part of a ribbon vibrator and at a portion thereofl may have outwardly extending spaced lips or parts 74 forming a type guide or aliner. A plate 75 may be secured to or formed integral with the arm 71 and this plate forms a ribbon holder through which the ribbon'76 is threaded. The plate or holder 75 has openings 77 and is provided with spaced parts 78 forming suitable guidesl for the ribbon on opposite sides of the printing point, said parts 78 being spaced apart -far enoughto permit the type to print against the platen. As the rod 68 is rotated oroscillatedby the mechanism already described, the arm 69 will move the link 70 andthrough the latter vibrate the ribbon old one.

The lever 63 is substantially bell-crank shaped and is mechanism holder 75 and aliner 74, thereby causing the ribbony to cover and uncover the point as each key is operated,

The ribbon extends beyond the sides of the ribbon vibrator and-may be guided in the ends 79 of the brackets80, said ends having slots 81 for the ribbon to pass through. The'ends ofthe ribbon are passed about spools 82 and 82. These spools are mounted to rotate on a fixed part of the printingy casing and are adapted .to be readilyremoved to permit-a new ribbon to replace an provided with a ratchet, rg toothed portion or member 83 formed ont `:he spool or separate therefrom as preferred, and adapted to engage the or dog 84. Each pawl 84 is pivotally held at one end to an arm '85, the latter being held to the rod or shaft 68, a spring 86v ednormally to force the pawl to' an en-` gaging position. The arms 85 are adapted to slide along the rod 68 and said arms for both spools are connected by. a transversely extending bar or element 87 havingv one or more substantially V-shaped projecting portions 88 adapted to engage notches 89 in said rod 68. The arms 85 are so positioned that only one pawl is engaged with the teeth of the toothed member of one of the Aspools at a time so that by shifting thebar 87 lengthwise of the` rod or shaft 68 one pawl' is disengaged from its coperating spool toothed side of the machine with a step-by-step movement. I i."he rod-A 68 is thus operated through the lever 63 and its connection with The' ribbon spools may each be teeth of each member is apaw-ll thus the ribvso being arranged on each of said arms adaptthe key action as previously described ,an-d ,v

by the rocking movement of said rod or shaft 68 the ribbon is moved lengthwise and also vibrated to cover or uncover the ing point as shown in full lines in'Fig. 1.

Any suitable means may 'employed as an escapement mechanism for letter-spacing the carriage. As shown the carriage has .a rack 90 secured to the base 89, and engaging this rack is a pinion 91, said carriage being attached to a iiexible connection 92 which passes about a spring drum 93 tendingnormally to force the carriage transversely of the machine. The pinion 91 is held to a ratchet wheel 93, and the teeth ofA this ratchet wheel are engaged by a'pawl 94 carried by a toothed wheel 95, said pawl permitting the carriage to be moved freely in one direction.

The toothed wheel 95 is engaged by the usual loose or'limber dog 96 and a-xed dog 97 said dogs being held to the rod 68 so that when said rod is operated by the depression of any of the key-operated levers 86, as previously described, the dogs will be moved to permit the toothed wheel 95 to escape and print-` ployed inv which thereby permit rthe carriage to move a letter splicevateach depression of a key-operated l 56 in" the usual way, it beingunderstooil'ffthat the escapement, may be operated through a source independent ot' the means employed r operating the ribbon vibratory ani'blrif hw se feeding means.
