l .Application filed February 4, 1908. Serial No. 414,200.

T o all whom 'it may concern:

Be it known that I, OSCAR VVooDwARD', citizen of the United States, and resident oi' MontclairI in the county of Essex and State of New fersey, have invented certain new und useful Improvements in Type-lVriting Machines, of which the following is a specification;

My invention relates to typewriting machines and more particularly to line lock and margin stop mechanism and the main object of said invention is to provide simple and efficient mechanism of the character specified which may be readily actuated to effect. a release of the line lock or to permit the carriage to pass beyond the position where it is normally arrested on its return movement by the margin stop mechanism.

'1I`o the above and other ends which will hereinafter appear, my invention consists of the features of construction, arrangements of parts and combinations of devices to be hereinafter set forth and -inore particularly pointed out in the appended claims.

VIn the vdrawings wherein like reference characters indicate corresponding parts in the various views, Figure l vis a vertical, front-to rear, central, .sectional 'vi'ew of a.

'typewriting machine 4embodyimg'my -invention. Fig. 2 is a front elevation of the same 'with parts sectioned and broken away. Fig. 3 is .an enlarged det-ail fragmentaryperspective View .with parts broken away and in scction of the line lock mechanism. Fig. 4 is a I'fragmentary detail front elevation with parts 1n section showing portions of the line lockl and alarm ,.mechanism. Fig. 5 is a flan View of thesame.- Figi 6 is an en'- i arged detail-bottomv view of the adjustable margin stop and the partsassociated theilewith. Fig.l 7 is a plan .view of 'the same.`

Fig. 8 is any enlarged detail sectional View taken transversely through the forward lixed carriage rail or track and showingpoitions of the line lock and alarm mechanism. Fig. 9 is a transverse sectional 'view showing tlhc combined line lock .and margin stop in the released position.

In the -various views parts of theitype' writing machine unnecessary to.an, understandlng of invention have been omitted.

I have shown my invention embodied in the resent instance 1u a front-strike typewritlng machine, thoughl't should be underrotate.

ported by risers 6 and 7 respectively, whichA extend upwardly from the; top plate' of the machine Antiffriction balls 8 are received in the grooves of the fixed guide rails and in corresponding grooves in the forward and rear cross bars 9 and l() respectively ofv the carriage, said cross bars being united by end bars l1 so as to form a rectangular frame in which a cylindrical platen l2 is mounted to A feed rack 13 is connected to arms 14? pivoted at 15 to upwardly extending lugs 1 on the carriage. The feed rack 1 3 engages a feed pinion 17 which is operatively connected to an escapement wheel 18 co opera-tive with feed dogs 19 carried by a dog rocker 20. A forwardly projecting arm 2l on the dog rocker is connected to a link 22, the lower end of which is in turn connected t-o a crank arm 23 located centrally of a rock shaft 24 mounted in bearings in the base l ot' the machine. This rock shaftis'likewise provided near its ends with crank arms 25 which extend rearwardly from the shaft and .aire connected at their rear ends with de The universal bar extends transversely beneath the key levers 28 ulcruined on a fulcrum bar 29 secured by screws 30 to, The key leyers are the base ofthe machine. provided with the usual 'finger keys 3l' and with restoring springs 32.
