Application filed May 9, 1906. Serial No. 316,027.

To all whom it may v Be it known that I GEORGE A; SEIB, a citizen of the United States, and a resident of Syracuse, in the county oi' Onondaga and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification. v

My invention relates more especially to the ribbon 'mechanism of that class of typewriting -machines wherein a vibrator or carrier is employedto move the ribbon to cover and uncover the printing point during printing operations.

The mainobject of the invention is to provide improved means for dispensing at will with the-vibratory movement of the ribbonso that it may be maintained quiescent and without'the printing field on the platenv during printing operations.

To the above and other ends the invention consists in the features of constrhction; combinations of devices .taken on a plane representedby the linen -win Fig.1

and arrangement of partslhereinafter fully described and particularly pointed out in the cljaiins. v

One form of my invention is illustrated. in' theaccom-f' panying drawings, wherein I I i 1" Figure l is a vertical ironttoiar sectional view ofa typewriting vmachine embodying-any invention, of said machine being ,omitt'ed parts'beingbrokenf away; Fig. 2 is a sectional view showing-the right hand side of the lower partof omitted and heing brokniawayathe section being and looking in the direction-{of the a ows at-said lin Fig. 3 is an enlarged fragmentaryl horizontal detail sectional view the iconnectio'nlbetweenthe versal bar and-the link-for actuating the vibrator operating lever.-

LA sub-lever 7 is screw 15 to. a segmental type baisupport 16. The type bars are radially arranged in segments of circles and their type ends which normally rest on a segmental pad 17 are adapted to cooperate with the front face of a rotary platen 18. The platen is supported in side bars I 19 of aplaten carrier or carriage which is composed of the side bars 19 and a longitudinal rear bar 20 from the ends of which the sidebars project'horizontally forward The rear bar 20. is provided at its top and bettorn with longitudinal grooves which cooperate with anti-friction balls 21 said balls also cooperating with fixed top and bottom grooved guide rails 22, said guide rails being secured by screws 23 to standards 24.-rising from the top plate.

mally meshes with a feed pinion 26 mounted'on-a shaft which is journaled in a fixed bracket 27. An escape-' nent wheel28 is operatively connected with the pinion shaitand th e pinion 26, and 'escapement dogs .29 are adapted totcoiiperaxe with said escapement -wheeLsaid dogs .being mounted at the topoi the upright arm 30 of -a pivotedyibratory-dog carrier or' rocker 31-, said rocker lbeing provided with a horizpntalfiarml'32twhich carries a pin 33.

The uni:-

versal bar extends from side to side of the machine bedown about the pivots 41, through the link 35 on the dog rocker 3 1 andjcausing the e scapement dogs I I 29 to cooperate in aknown mannerfwith the escapernent the machine is--' Supported on tlie'carriageis a feed rack 25 whichtnor 1 yneath the series of key levers;4 and when any key lever 1 V is operated said universal bar is adaptedto befswung' wheel '28, ,A carriage dron li44 ismonnected by a bandor-strap 45 with the carriage andtend's constantly 1 to draw the carriage leftwardgacross the top'plate oi the machine. At each operation of a printing key, itsasso ,ciate type bar is swung to and from the printing point, and the escapement devices cooperate to permit the carriage to be drawn a units distance in printing direc tion under theinflnence of the spring drum 44. During their up airddown movements the printing key levers 4 are guided near their rear ends between teeth or reeds 46 projecting upwardlyfrom acomb plate or reed bar 47, which'errtends'irom side to side of the'machine beneath the key levers and is provided a t its ends with angular arms 48 which are secured by screws 49 to ribs 50 on'the base 1 i i I Y A pair of ribbon spools -51 arranged above the top plate and forwardly of the platen, .one at each side of the machine, receive a ribbon 52 which may be fed lengthwise from either spool to the otherby any suitable means, preferably that employed in the Monarch machine and which is explained in the patent to Felbel &

Gabrielson, No. 703,339. dated June 24tl1,-1902. Only theleft hand one of the ribbon spools 'is shown in the drawings. Each ribbonspool 51- is carried by an up- .right shaft 53 which rotates in a fixed bearing 54 and is adapted to be connected by a suitable gear train with a driving or power shaftj55, whiclr'shait is connected by beveled pinions 56 and 57 with the carriagespring drum 44. As explained in the above cited patent the' driving or power shaft is. capable of longitudinal movement and the longitudinal position of said shait determines which ribbon spool will be turned to wind the ribbon thereon.

Between the ribbon spools the ribbon 52 is threaded through a ribbon vibrator or carrier 58 which is supported and guided in a bracket 59 suitably secured to tion of the link is flattened and besides carrying the stud is provided with a downwardly andforir-ard 1y bent arm-69. The lower end portion ofthe link 68 is fiattened as indicated at 68' and the flattened portion is provided at itslower end with a hole or opening '70 ,(Fig.

3) in which engages-a pin or rivet 71'projecting laterally rightward fromthearm 37 of the universal bar frame.

The end of the pin or rivet is rounded as indicated at 2 i for ready engagement with. thefhole or opening 70.

Olamped between the head 7 Softhe pin"or rivet 71 and one side of the arm 37 is the end of a flat securing spring 74, which, as best shown in Fig. 3, is thus con-, nected to and carried by the arm 37. The rear or free end of the spring bears against the link 35 and serves to maintain it in engagement with the pin 36.

The link 68, which is' on the opposite side of the arm 37,. is adapted to be maintained in engagement with the pin 71 and to be disconnected from and reconnected thereto by means presently to be described.

Said link 68 is arranged to b e'swun g fore and aft of the machine about the pin 7l' in order to cause the stud 66 to move longitudinally of; the slot 64 so that said link may engage the operating lever 61 at varying distances from its fulcrum, thereby varying'the power arm of said lever and causing the ribbon vibrator to throw the ribbon varying distances from normal position.- The means employed for swinging the link about its pivot 71' inthe present instance comprises an eccentric 75 fixed onthe power shaft and rotatable with the latter. Said eccentric is embraced between the flattened upper I portion of the link 68 and the arm 69 thereof, the arm 69 and the upper portion of the link 68 constituting a strap for the eccentric andone which afiords'an up and and said eccentric 'will cooperate with the strap of the link 68 to move the pin 66 back and forth in the slot 64. In assembling the parts the head 67 of the pin or stud 66 is passed through the enlarged opening 65 at the rear and of the slot but during the back and forth movements of the pin 66 under the influence of the eccentric. said pin is-never moved rearwardly in the slot as far as the enlarged opening 65. The diameter of the head 67 of the pin 66 is greater than the width of the slot 64 so'that during the operation of the parts the link 68 is constantly'or at all times connected with thc operating lever 61 and cannot be accidentally detached .from it.

with the pin 71- on thc univ ersal bar .as'described, said barwhen any of the printing keylevers 4 are operated,

' and the operating lever 61 will be turned on its fulcrum 62 by said link, throwing or moving the ribbon vibrator 58 upward variable distances. The upward move v 'ment of'the vibrator carries the'ribbonfrem a normal inoperativeposition below the printing pointupward 'so:that said ribbon covers theprinting point and the typeoi the actuatedv typebar will cooperate with the paper and platen through said ribbon, thereby causing an inked impression to be made on the paper. Sometimes a 10f the'ribbon between the types and thepaper. .By

my invention this result is accomplished bymeans which are operative to disconnect the actuating link 68 from the universal b'ar frame, so that when the universal bari's operated by the printing keys, the link will not be moved by said universal bar, and the operating lever and the vibrator will remain quiescent-and the ribbon will be maintained in normal position below the printing point. The means for disconnecting the bar framewill now actuating'link from the universal be described.

A horizontally disposed angled bracket 76 is secured to the comb plate or reed bar 47 by headed screws 77.
