to yield rearwardly away from the framethe type is against a yieldingly su ported' upper end is provided with a laterally projecting bracket 24, in which is journaled a platen 25. Theplaten is of the usual construction, and extends across the auxiliary frame of the carriage and is arranged in line with the type when striking the paper, so as to form' the usual backing to receive the blow of the type. Said platen as clearly shown in Fig. III, is mounted in a movable boxor bearing 26, at each end thereof,

which box is guided in the bracket 24, and held spring-pressed forward by a coil spring The springs 27, will allow, the platen for the paper, and consequently the-blow of platen. Rigidly mounted on the s aft of the platen, a t-each end thereof, is a gear wheel 28. The frame 12, carrying the paper is formed with a rack on the 'rear face of each of its side members, and these racks engage respectively, gear wheels on the shaft of the platen. It will readily be seen thatiupon the rotation of the platen, the gear wheel 28, operating upon the racks earned by the frame for the paper will move'the frame vertically in the auxiliary v .frame of the carriage. The racks formed tially horizontal. when on the side members of the frame, and the gear wheels carried by theshaft of the platen are formed with teeth which are so shaped that the engaging faces are substansupporting the frame, and therefore, all-tendency of the tooth connection between these parts to slide one over the other, caused by the usual camshaped tooth, is avoided. The platen is'provided at each end with the usual thumb Said spring dog will perate to hold the 0 a will be carried in a flat conditio vertically fsions from the t e.

pieces 29'. I have also provided at one endof the platen, a spacing lever 30. Said spacing lever is. freely journaled on the platen shaft, and is held by a spring 31,

against a stop pin 32. A pivot dog 33, car

rled by the spacing lever engages a'ratchet wheel 34', which is rigidly mounted on the shaft of'the platen. 'A stop pin 35, 'willserve-as a limiting means for the movement of the spacing lever. In order to hold the platen in its various adjusted positions, I have provided a spring do 36, whichcarries a roller at its free en which engages between the teeth of thegear wheel 28.

frame for the paper-in Its various adjusted vertical positions. Itwill readily be seen therefore, that as the platen is turned, the paper will not only be carried vertically by .'the movement. of the platen, but the frame 'which supports" the paper will also be moved vertically and the sheet of aper.

I substantiall rollers 43, that engage a second; track bar These rollers allow the I on the main frame. carriage to travel transversely across the machine, and the transverse movement of the carriage conveys a similar transverse movement of the frame carrying'the paper,

and said frame for the paper. is movable rnly in a vertical direction relative to the carriage. It will readily be seen that the frame carrying the paper may be raised vertically relative'to the carriage and removed from the machine, the bearings for the'platen yielding to allow the frame to pass. 1 This allows the ready insertion of new sheetsof paper and carbon sheets if desired for manifolding. It will be obvious however, that the paper may be inserted while the frame is in the machineif desired,

Theauxiliaryframe of the main carria e is supported in the carriage by lugs .44, w ich engage the frame work of the machine. As a means for moving the carriage across the machine, I have provided the usual coil spring 45, which is secured to one end of the carriage and coiled in 'a' bracket of the well known character in this type of machine.

A toothed bar 46, is rigidly carriedby arms 47 which are pivotally attached to the lower member of the carriage. Coil springs v 48, engage said arms 47, and normally press the toothed bar downward into engagement with a toothed wheel 49. The teeth of the bar .onythe side facing the coil spring, are

ment with t e teeth of the toothed wheel'49,

said bar and the carriage attached thereto are prevented from movement in a direction totheleft, as viewed in Fig. II, except as the toothed wheel is allowed to turn by the escapement. The yielding sup ortforthe toothed wheel, will however, al ow the carriage to be moved to the right whenever it is esired. The toothed wheel 49, asclearl shown in Fig. I,',is; suported by theantlfriction .balls 50, which engage recesses formed in each face of the toothed wheel, and corresponding recesses or tracks formed .in a bracket 51. This manner of supporting the toothed wheel will allow the same to vertical and when in, engage rotate freel' when released by-the es'ca ement.- Sai toothed wheel is rovided with a central opening 52, and is ormed with a plurality of teeth 53, which coiiperate with an escapement pawl. Said escapement pawl 54, is carried by a bar 55, and-has oppositely disposed cam teeth 56, and 57. The bar for supporting the pawl 54, is mounted on parallel links 58, and 59, which in turn are pivoted to arms carried by the frame 'of the machine. a

\Vhen the bar 55, is at the rear end of its stroke, as shownin Fig. I, the tooth 56, en-

gages one of the inner teethof the toothed wheel, and prevents said toothed wheel from being turned by the spring operating upon opposite side of the pawl will engage one of the teeth on the opposite side of the toothed wheel 54. When this engagement is brought about, the cam face 56, will released from the tooth which it engaged, and the toothed wheel will have moved half the distance between its teeth. On the return movement of the bar 55, the cam face 57, will allow the toothed wheel to move again half the distance between'its teeth and the cam face 56 ofthepawl 54, will engage the next inner tooth on the toothed wheel. It will thus be seen that by one movement of l the bar 55, a half escapement occurs, and on 'the other movement of the bar, the remaining half occurs, thus requiring a forward and backward movement of the bar to allow the escapement of a single tooth.

The bar 55, is connected. by means of a link 80, to a bellcrank lever 81. Said lever at its lower end is connected to a spring 82, which, in turn is pivoted to the frame of the machine, and which spring operates to hold the bar 55, at the rear end ofits stroke. The bell crank lever 81, is rigidly attached to the universal bar 60. The spacing bar [61, is carried by a lever 62, which is pivoted on the frame of the machine, and en- %ages the upper face of the universal bar 60.

y depressing the spacing bar, the universal bar is moved downward, which operates the escapement and allows the carriage to move the distance of one tooth transversely of the machine. The downwardly projecting In 4, carried by each key lever 1s also locate directly above the universal bar 60, and when a keylever is depressed, the universal bar is alsodepressed, thus causing the operation of the ,escapement.

In order that types carrying small letters and capital letters may be brought into action when desired, I have provided each type lever with two types 63, and 64. The type 64, is rigidly mounted, in a socket in t e type lever in the usual iiianner. The

type 63, is mounted in a n ovable bar 65,

which slides in. a suitable bearing in the outer end of the type lever. Said bar at its .lower end carries a in 66, v hich eng es a slot in-a lever 67, pivoted to the end 0 the type lever. The spring 68 normally depresses the outer end of thl lever '67, and holds .the outer facefof the t pe 63, positioned below the outer face- )f the type 64, so that when the parts are an the position shown in ,FigLVIII, the typi 64, will strike the paper resting against the platen, and the type 63, will be ineffective. lever is moved to its normal noperative position, shown in Fig. I, the 0 iter end of the lever 67, strikes'the rest bar, and moves the lever 67, against the actionoi the spring 68, so asto throw the surface (f the type 63, above the surface of'the type 34. A gravity latch 69, will engage ashouli er on the type lever and lock the lever 67 ill this position, holding the type 63, rigidly LbOVG the type 64, so that when the type'lei er is swung to bring the type into en age] cent with the paper, the type 63,-will. ef ective and the type 64, will be ineffective or ino erativea When the type The type v63, preferably cai ries t e small letters. When it is desired to bring the" type carrying the large lette rs into operation, the shift key 70, is d pressed. The key lever carrying the shiftk is connected by means of a link 71, to a b a l crank lever 72, carryin machine. The depression of the 70, throws thebar 73, into en; the latch on eaclitype lever, thus releasing the lever 67, allowing the sp1ing6 8, to depress the lever 67, throwing thetype 64, lnto action as soon as the type lever is moved from the rest bar. ing the shift key is'also provit ed with a link 74, which is connected .to the uter end of a lever 75, fulcrumed on the d apending arm 76. Said lever 75, engages the under face of a bar 77, which is rigidly connected to the outer side'pieces of t e at xiliary frame forming a part of the carriagl When the shift key is depre ssed, thelever 75, will be operated, which in urn will raise the auxiliary-frame of the :arriage, thus lifting the platen, and the f] ame carrying the paper, so as to position tl 1e same prop:

erly for ,the action of the othe P type carried by the type lever.

- It will be obvious that min )1 changes in the details of construction may be made without departing from the s irit of my invention. In the place 0f.pr( viding a rest for the lower end of a sheet )f paper, and using separate sheets of paper, I may mount a roll or'rolls of'papen attthe lower end of the paper support ng frame, a1 (1 provide the T] ve lever carry a bar 73, extend ing across the shift key agement with usual combined 'clamp and :utter at the upper endso thatt paper iaybe drawn across the paperisu rtmg fame, and'cutlw off by the cutter at the upperend in the usual well known manner.

Having thus described my invention, I

claim sheet supporting frame movable with said carriage; and means for. simultaneously operating said platen and moving said sheet supporting frame vertically.
