Original application filed January 13, 1921, Serial No. 436,'924. Divided and specification gf Letters Patent.
Patented May 30, 1922.
this application filed May 27, 1921. serial No. 473,161.
To all whom t may concern.'
Be it known that we, EDWARD BERNARD Hess and Lewis CARY MYERS, both citizens of the United States, residing in Brooklyn, county of Kings, cityand State ot New York, have invented certain lnew and usetul Improvements in Typewriting Machines, of which the following is a specification.
T his. application is a division of our application for patent tiled January 13, 1921,' No. 436,924-,
In the application mentioned we h av shown a fully organized typewriting machine possessing most of the characteristics of the Royal Standard machine, but which is, by a novel construction and arrangement of the mechanism, made small, compact and portable. The portable machine ot' said parent application embodies various improvements in typewritinp; machines which are claimed in other applications for patents copending herewith. In the present application we have directed our claims to certain novel organizations and constructions whereby cert-ain parts of the mechanism 'are so supported and operated that they are arranged obliquely and move obliquely when shifted Yfor case printing, so that the writing may be at all times plainly visible in a machine where the platen is located lower than in standard machines.
According' to the invention herein claimed, the over-hanging carriage is supported on a carriage track and that part of the 'carriage in which the escapement oscillates is formed with an extension projecting downwardly to a point where vit contacts with an adjustment screw carried by the back portion ot' thebase trame ot' the. machine, ln such construction the extension will not` permit a rocking movement at its lower end, and this prevents a fore and aft movement ot the This way ot suspending the carriage upon the track may be applied to other types of machinesq especially those ,in which the carriage runs on three bearing points instead ot tour, or where there is a tendency for an over-hanging of the carriage,ieither forward or backward and particularly where sheet metal parts are sub4 stituted 'for the heavy castings ordinarily used.
The machine is'so built that the carriage shift rail or track and the frame which sup ports the escapement mechanism are rigidly connected and this same frame connects with a rail or rod on the carriage trame andof the mechanism which operates the escape- Inent Figure 3 is a similar view illustratingl the mechanism to1` sl1it'ting` the carriage for case printing;
Figure 4 is a `perspective view, largely diagrammatic, and with many parts broken away to show thc relation oie/the various parts ol. the mechanism tor shitting the carriage obliqucly tor limiting' its up and down movement and for operating thc escapement.
The trame ot the. machine is indicated at A and B indicates some ot' the type key levers which operate a universal bar (l, as well as the type bar. These leversare pivotally mounted on a'rod c mounted in a trame I) and these levers are connected by links c, t0 t'ront links or levers E, in turn connected by rods I" with the type hars (i. '-lhe levers 'E are pivotally supported by a rod c mounted in a traine ti. attached to the 'frame D. The
type bars (i are pivotcd in the usual way to a segment, ll and are supported when idle on a type bar rest l. A space key Z is connected -by levers 2 with the universal bar and this lever is pivotally mounted on the rod a. Ribbon spools are indicated at l( and the type bar guide at L. The )daten M is mounted in a carriage comprising` the side plates N and a rail O, which is supported by a shit't rail l1 anti-friction balls a being interposed between the two rails. The rails are held in proper relation to each other by clamping plates o. A
A jr'rame Q is seein-ed to the shift rail and extends rigidlytheretrom and supports the rocker R of the escapement mechanism. The shit't rail P has downwardly extending legs links S which extend forwardly and upwardly from their pivotal connection at s2 with the machine frame. This pivotal conneetion is adjustable so that the inclination of the carriage as a whole may be changed to render it more or less oblique.
The upper portions ot the legs s are pivotally connected at t with levers T secured to a rock shaft Tl pivotally mounted in the frame at t. One of the levers T has an arm 252 connected by a rod u with the upwardly extending arm u of a bell crank lever U pivoted at to the frame D and extending into the keyboard where it is provided with a finger piece u. By means ot' this key the lever T with which `it is conneeted may be operated to raise the shit't rail and consequently the platen and its carriage. A spring u* attached to an ear t5 of the lever T and to the bottom o't' the trame A serves torassist in lifting the carriage and in counterbalancing it.
ln order to lock the carriage in lower case position. we employ a latch V which engages a lug 'a on one of the legs s of the shift a-il.
A rod V is connected to the lower end of the latch and to the upper end ot' the lever ll. A spring V2 tends to hold the latch in engagement with the lug i'. ll'hen the tinger piece u* is depressed the latch is released and the lev-er T is operated to raise the earriage for upper case print-ing.
The devices shown at lV are tor locking the mechanism when desired in upper case position; but they are of usual construction and -need not lbe further described.
The escapement rocker B is operated by a lever R pivoted at l" and bearing on a roller 7" carried by a spring arm r2 of the rocker and saidvlever It is operated by arod R connected wit-h an arm o ofthe universal bar.
The trame Q is rigidly secured to the lshitt rail P and it supports a roller J and a pin J arranged on opposite sides of a rod J2. connecting the rear ends oi' the two 'side plates N of the carriage. As the carriage moves back land forth ovel' the shift rail it is partially supported and guided by this rod. the roller and the pin.
An arm Q. extends downwardly and rearwardly from the frame Q and beal's against an adjustment screw Q2 mounted in the rear part of the. frame A.
Inasmuch as the carriage overhangs its front supports and as the carriage ls a ioat- 'ing one. being supported Vatthe front by the shift rail which is in turn supported by swinging links aml levers` there is a tendency t'or the carriage to sag. but b v means ot' the brace arm Q in cooperation with the front supports ol' the carriage this tendency is obviated, as by means ol' the set screw Qz a torsional strain can bc imparted to the sub` frame of the a'rriage which vwill canse it to always maintain its proper oblique arrangement without any material change. In this way we provide what. may be termed an aligning arm which extends from the shift rail or. arriage support to a rigid abutment.
ln order to limit the up and down movement ot' the carriage we provide stops B', B2. B. B4. The stops B. B2 are mounted in a bracket BI attached to the left hand rlage is moved obliquel) Jfor case printing,
but the same organization ot' mechanism may be used in other machines. Some of the mechanism herein Ashown and not claimed is claimed in other copending applications. 4
