TYPE-WRITING MACHINE.

.Application led October 7, 1916. Serial No. 124,260.

VTo all whom z't may concern:

Be it known that I, GEORGE A. SEin, citivzen of the United States, and resident of Ilion, in the county of Herkimer and State of New York, have invented certain new land useful Improvements' in Type-Writing both ends of the .carriage travel.

To the above and other'ends -which will hereinafter appear, my invention consists in certain features of construction and 'combinations and arrangements of parts, all of which will be full set forth herein and particularly pointe out in the claims..

In the accompanying drawing,

Figure 1 is afragmentary left-hand side `elevation partly in section of the upper part of a typewriting machine having my invention embodied therein, only those parts beingv shown which contribute -to an understanding of the invention.

Fig. 2 is a front view of the left-hand end of the `platen and its supporting means, parts being shown in section on the line m of Fig. 1. l

Fig. 3 is an end elevation, partly in section, showing the left-hand end piece of the platen frame and my adjustabledevices, vthe section being on the vline y y of Fig. 2 and looking in the direction of the arrows at said line.

Fig. 4 is an enlarged'fragmentary section on the line z z of Fig.43. l

Fig. 5 is a diagrammatic plan view on a I have shown my invention embodied' in a machine which in some respects is similar to, and may-be identical with, the No. 10

Remington typewriter, but which in other Specification of Letters Patent.

respects is different from that machine. The machine shown in the drawing comprises a top plate 1, which below the platen 2, is depressed into .a trough-like form as in the No. 10 Remington. Said platen has an aXle 3 which is mounted by means presently to be ,described in a platen frame, of which only the left-hand end piece 4 is shown in the drawing. Said platen frame may be mounted with provision for an up anddowr caseshift motion in a carriage truck, which truck is not shown in the drawing but which may be identical with that of the No. 10 Remington machine. Said Remington truck comprises a rectangular "frame, the front and rear bars ofwhich are lin the nature of grooved rails, which through roller bearings coperate with stationary railsmounted on 4,

the top plate 1. All of this mechanism, in-v differs from that of the Remington No. 10y

m chine, however, the :type bars 5 being guided in a Series of radialslots 6 in a. type bar segment 7 and all of saidtype bars pivoted on a curved wire 8 suitably seated in a, curved groove in the -rear face.V of 'said segment.l Said segment is secured in :any suitable -way to brackets 10 of the top plate 1. Each 'of saidtype bars hasa slot11 in which plays a pin 12 projecting from a'ke'y oper- 'ated sub-lever 13, the jwhole construction being such that whenakey is depressed said pin 12 moves toward the front yof the machine and throws the type bar from its ynormal horizontal position up 'to its printing position shown in Fig. 1. One or the other of the two types l4`will strike against the front face of the platen depending ton the case position of ,the platen. A center-guide 15 for the type bars is mounted onthe segment 7 On the front face of said-- segment, as in some prior machines, there is an anvil 16 formed on acurve in a vertical plane and against which each type bar strikes at about the instant of printing. It is always desir- \able vto have the two ends of the platen bear at all times the same relationvto the typesl by the anvil 16. For this purpose I have so that a wrench can be used on it.

provided a plate 17 which is secured to they inner face of the end piece 4. The axle 3.

passes through a sleeve 18, part of which is exteriorly screw threaded, and the plate 17 has a hole which is correspondingly internally threaded and the sleeve 18 is screwed into said plate. Said sleeve has an enlarged part 20 forming a shoulder which is screwed up tight against the plate 17, said enlarged part as here shown being formed polygonal A check nut 21 is valso screwed on to the threaded part of the sleeve 18 tight against the lefthand tace ot the plate 17 so that the sleeve 18 is rigidly secured to said plate 17.l The end piece 4 is madewith a hole 22 large enough to admit the nut 2l with provision for more or less motion of said'nut in a front and back direction. In other words, the hole is larger than the nut. rllhe plate 17 is secured to the end piece 4 by means of two screws 23 and 24, the one located in the 'vertical plane of the platen axis, in this instance directly below said axis, and the other preferably directly above said axis. @ne of said screws, for example, the screw 23, passes through a round hole in the plate 17 and is screwed into the piece 4; but the other screw 24 passes through a slot 2 5 in the plate 17 which slot may be 'formed on a curve concentric with the screw 23. Another slot 26 is formed in the plate 17 and is elongated in a direction toward and away :from the screw 23. A screw 27 with an elongated head eccentric to the shank or threaded partof the screw, passes through the slot 26 and is screwed into the piece 4, lthe head of said screw 27 being of a diameter corresponding to the width of the slot 26..

1n adjusting the machine the carriage may `be moved to its extreme left-hand position and a gage is set against the front face of the right-hand portion of the platen which at that time will be at the printing point.'

The carriage may then be moved to its extreme right-hand position and, the screws 23 and 24 being in place but not tightened,

the screw 27 is turned one way or the other, the turning of said screw on account of the eccentricity of its head rocking the plate 17 one way or the other' about the screw 23 .as a center. As said screw 23 is directly-beneath the platen axle, turning the screw 27 will eEec-t a line adjustment of the lett-hand end of the platen toward the iront or back ot the machine. By this means' the left-hand end of the platen is adjusted exactly to the gage which has previously been set to the riUht-hand end of said platen. When the let-hand end of the platen has been thus accurately adjusted it is secured in adjusted position by tightening the screws 23 and 24. When this has been done both ends of the platen and therefore, of course, all parts of the platen will be set in exactly the same lrelation to the type bars when any of said bars is in contact with the anvil 16.L

1t will be perceived that the etti'ect of the adjustment described is to set the front or printing face of the platen in exact parallelism with the carriage rails, or parallel with the direction of carriage travel.

While in practice have found it necessary to employ only one set of the adjusting devices, it` will be understood that two such sets may be used, one setLat each end of the platen. 'Agaim though I have applied my novel adjusting devices at theleft-hand end of the platen, it will be understood that in some makes of machines it may be desirable or necessary to apply said adjusting devices at the right-hand end of the platen.

The character of the adjustment provided by my novel means., is diagrammatically illustrated in Fig. 5, where, the broken line 28, drawn through the front face of the right-hand end of the platen parallel with the direction ot carriage travel, represents the correct position of the said front tace or writing line. 1f the left-hand end of the platen is found to be vforward of or behind this line, it can be adjusted toward the back or front until it is brought exactly ,to said line 28. ln this gure of the drawing the left end of the platen is shown, in an exaggerated way, behind its proper position, and is to be adjusted toward the front.

1n the drawing the invention is shown applied to a trontstrilre machine, and in such case the adjustmenty is in a frontiand back direction; but in a machine in which the types strike at some different angle, as in a top strike machine, for example, the adjustment would be in a correspondingly different direction. 1n some of the claims l have referred to the adjustment as being in printing point direction, meaning in lthe direction of the radius of the platen at the printing point.

lt will be noted that the platenl axle has a long bearing 1n the sleeve 18, that said platen frame.

ture asv itAwould have been if the adjustment had not been provided. j

Various changes/can be made in the details of constructionand arrangement without departing from my invention.
