In the aeeompanving drawing. in whirh is illustrated one of the various possible em llodiments ot the several features of the invention. Figure 1 is a plan view showing sueh parts of a typewriting machine as are nQePsSHly to illustrate the application ot' the present invention thereto Fig. is a side levation of the parts shown in Fig. 1; Fig. 3 i. ii front elevation with eertain parts lit-in; shown in startion. or hrolten away. for the sake of elearness.

imilar rel'erenee eharaeters refer to similar parts throughout the tlitlerent views of the drawing.

While the pres nt invention will he tile, serilletl hereinat'tw with relation to its appiieation to a noiseless tvpewritinglf machine in whi -h the type earriers are radially tllS posed with respeet to a eonunon printing point and oaet with th platen by pressure in "mtradistitn-tion to impart. it i of nurse. t he nndewtood that this meehanism niav he. applied to other forms of t) pe- 'writim: maehines as well without departing deserilie anv torni ot tvpe aetl n and ass eia ed a,

in those l as the tunrtions are well lauown ainiliar with the ar ltel'erl-ing' now in detail iv the aerompanving' drawing and more partimlarlv to Figs. 1 and 2. a platen roller 1 is carried by a earria 'e 2 traveling along: a horizontally disposed shift rail :3 in the usual well-known manner. letwe n the end wails l f the platen earriae'e and positioned adjacent o the platen roller is a flat ;-heet-metal platen adapted t talt'e up he thrust or pressure the type tarriers one o \\illt'll is indr rated at i "th pap r is adapted to he ted downward alvout the platen roller from a pap r tal'le t). and upward o er the flat pla n ext nding aer ss the l'ront ol the platen roller.

.\mon;1 the several meam used l'or hold" ing the. paper in engagement with the platen. there is provided what will be termed hereinafter tor eonvenienee. an alining scale" 7 of flat sheet metal provided with laterallv extending arms at earh side eo-aeting with a relatively large s'art'ar of the flat platen I). or havin; a t tal spread of perhaps halt the length of the platen roller, This seale. whit-l1 is ul ti a printing; point indleator. is provided. al.-.o with downward twtendin; 2ll'lll, ltl lormed Y MWWAWWWWH ill integrally with the lateral arms and having rearward extending ears 11 attheir lower ends. through slots in which pass adjusting screws 1; engaging tapped-out portions on an auxiliary bracket 13 carried by a main bracket ll secured in any desired manner to the shift rail 1) along which the carriage travels. It is to be noted that the arms 8 and 1" carrying the scale 7 are. all ()1 one piece. but not necessarily so, it being easier and cheaper to make the parts in this manner. The auxiliary bracket 13 as shown more clearly in detail. Fig. 3. is mounted upon trunnions in the form of adjusting screws 15 passing through the sides of the main bracket ll and provided with lock nuts 16 in order to maintain them in adjusted position. The screws passing through the ears 11 in the alimng scale are adapted to permit an independent vertical adjustment ol the alinint: s ale T in order that it may properly coact with the lower edge of the printing line. The. adjusting screws 15 supporting the aux iliary bracket are particularly adapted to permit lateral adjustment in order that the indices upon the alining scale 7 may properly coact with the central portion of each printed character. the vertical and lateral adjustments being capabl oi being made independently of each other. It, is. of course. to be understood that atter these adjustm nts are once made. further adiustments will probably be, unnecessary.

The alining scale 7 is spring pressed against the platen or paper. it in place, by a flat spring 17. secured by means ot a set screw IN to the rear of the main bracket ll. which bears against the upper ed e of the auxiliary bracket l as shown in lig. 2.

Th right and lelt hand ends of the alining ?ll( proper are onnected across the open renter exposing tin printing point by an upwardly extending arch d portion 20 whi h i al o ruricd backwa d above the printing point. as rllwz' a in Fig. 2. thereby to detlect the paper and hold the same in contact with the platen roller.

The hape of the central opening in the upward extending portion it through which the type pass when making the printed inr pres ion. is ol' importance. since it. guides the l'eeding ol the paper. and du to the curved arch particularly prevents the cor-- tiers of the paper from catching in the opening it the corner happens to be just above the inner edge ol the laterally extending portion N ol the scale when the carriage is inoyetl to right or let't. or it the paper is l'ed into tlumachine in such position that th orn r thereol'. would tend to enter or pass out of the opening. The inner ends of the latcrallj, extending arms H of the aliniug scale are turned slightly l'orward away from the platen as shown at 3] in Fig. l to prethe printing point.

vent catching of the paper during the letterspace movement of the carriage. The upper end of the arched connecting portion 20 is provided with a V-shaped notch, the space between the two upper points of which represents the writing space or width of one letter and the bottom of the point of the V being directly above the center of In a machine using the pica type, for example, the printing space would be .10, so that the opening of the V would be of that amount in such a machine. The two upper points of the V are also a certain number oi lines above the normal writing line so that when inserting a character the space in which the same is to be inserted, is brought into alinement with the points of the V and then the paper is fed backward to the printing line. the line-space mechanism of the platen roller coi'itrolling accurately the position thereof. In order that the writing line may be exposed as much as possible, the scale is provided with openings 24 at each side of the printing point which assist in making the line being written. as near visible at all times as possible.

In a double-shitt machine using straight thrust type carriers in which the type are positioned one above the other with their printing surfaces in substantially the same plane. there is, when writing a large number of sheets a tendency for the upper and lower type to overscore or underscore the printing line. The present alining scalchas an important relation with the paper-feeding qualities of a machine of this character, as it holds the paper more closely against the platen mileand back of the plane of the flat platen thereby preventing buckling or swelling of the paper at the printing point. thuseliininating the tendency to overscore and underscore during the printing operation. The oven-scoring is prevented by the rearward curved arched portion 20,

while the underscoring is prevented by means of a plurality of flexible spring arms or lingers 25 riveted to the arms 10 supporting the alining scale. These arms 23 extend backward against the platen roller, as clearly shown in Fig. 2 and are made of relatively light resilient material to hold the paper against the platen roller just below the flat platen 5. thereby materially assisting in the elimination of the tendency to underscore.

The present device tray serve either as an alining scale or a card holder, but when intended to hold cards it is preferred to introduce additional spring tension intermediate the scale. and final point oi resistance. This mechanism comprises a resilient arm it; extending downward l'rom the auxiliary bracket and is provided with a forward eX llt) trailing; pnrtiun 27. the, forward einl of whil-h forms a heel; tn engage a pull wire 01' eenneeting link .30 extending tawanl the front of the maehine.
