. ments in Type-Writing Machines,'of which the following is a specification.

My invention relates to typewriting machines and n'iore'particularly to indicating means and to card or work sheet guiding devices therefor.

In practice it is often desirable or necessary in filling in partly printed blanks, index cards and the like to resort ,to line spacing different from any which'can be secured with the aid of the ordinaryline spacing mechanism. lleretofore it has been customary to attain this result by throwing the ordinary line. spacing mechanism out, of operation and throwing the fractional line spacing mechanism into operation. The operator could then turn the platen bythe finger wheels any desired extent but had to rely upon mere judgment or upon the eye to effect the desired extent of line space movement and to secure a uniform spacing between the lines.

-One of the main objects of my present invention is to overcome the above disadvantages and to provide indicating means 'by which a proper and uniform spacing between lines-can be secured.

To the above and other ends which will hereinafter appear-my invention consists in the features of construction, arrangements of parts and combinations of devices to be described in the following specification and set forth in the appended claims.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views, Figure 1 isa central sectional view of so much of the upper portion of a typewriting machine as is necessary to show my invention in its ap lication thereto. Fig. 2 is a fragmentary ront elevation of a portion of the same. Fig.3 is an enlarged detail fragmentary plan view of the left-hand endof the carriage showing the fractional spacing mechanism.

I have "shown my invention applied to a Monarch machine and to a card guide of the general character shown inthe patent to .26 at the free end thereof.

George A. Seib, No. 831,382, dated May 22nd, 1906, but it should be understood that the invention is capable of general application and may be applied to different machines and employed in .a different manner from that shown. l

The corner posts 1 of the machine support a top plate 2 on which the carriage is mounted to travel from side to side of the machine. A type bar segment 3 carries type bars 4 pivoted thereto at 5 and segmentally arranged and adapted to move upwardly and rearwardly to the printing point. Each type bar is pivoted at 6 to a rearwardly extending link 7 connected to the usual type bar actuating'mechanism. A type bar support 8 is carried by rods 9 that extend forwardly from the type bar segment 3. A platen 10 is mounted upon a platen shaft 11 journaled in end bars or plates 12 connected to a rear crossbar 13 provided with oppositely grooved tracks or race-ways 14 in which. anti-friction balls 15 are received. .The anti-friction balls are also received in oppositely grooved fixed tracks 16 secured by screws 17 to upwardly extending standards 18 fixed to the top plate of the machine. The ends of the platen shaft carry finger wheels 19 by which the platen is turned. Upon reference to Fig. 3 it will be seen that the left-hand platen head 20 is formed with line spacing ratchetv teeth 21 thereon. A line spacing pawl 22 is operatively connected to a finger piece 23 by which it may be actuated in the usual manner to cotiperate with the teeth of the line spacing wheel to effect a step-by-step line feed of the platen. A spring 2a is secured by a screw 25- to the carriage'and carries a detent roller The detent roller is adapted to bear against the teeth 21 of the line spacing wheel when the line spacing mechanism isin use. A fractional line spacing mechanism is provided, which comprises aifinger piece 27 secured to a sleeve 28 that surrounds the platen shaft. The inner end of the sleeve is secured to a disk 29 that bears against the outer face of a friction disk or Washer 30 which in turn bears against the left-hand platen head. The disk 29 has a cam groove 31 therein with which a bearing on the spring 24 for the detent roller 26 cooperates. The construction is such that when the finger piece 27 is moved rearwardly the corresponding movement of the disk 29 will be effected, thereby allowing the detent roller to come in contact with and bear against the teeth of the line spacing wheel without effecting a pressure on the disk 29. IVhen, however, the finger piece 27 is moved forwardly, as shown in Fig. 3,

be moved to any desired extent, thus providing for fractional line spacing.

A front plate 32 is secured by screws 33 to depending lugs 34 which project from the top plate. A bracket 35 is secured to the front plate by headed shouldered screws 36. The bracket 35 is provided with forwardly extending ears 37'which support the pivot rod 38' that extends through openings in cars 39 on a card guide designated as a whole by the reference numeral 40, thus pivotally connecting the card guide to the bracket 35. The card guide 40, which is located centrally of the machine, has depending cam fingers 41 with which forwardly extending fingers 42- on a slide 43 are adapted to cooperate. The slide is mounted in place on the shouldered portions of the screws 36 which are received in slots id in the slide. A spring 45 is coiled about the pivot rod 38 and exerts a pressure against the card guide to force the up per end thereof toward the platen; The card guide is likewise provided with a pointer 46 which cooperates with a carriage scale 47. If desired the slide 43 may be moved upwardly to cam the fingers 4 1 forwardly, thus forcing with positive pressure the upper end of the card guide toward the platen. The construction thus far described constitutes parts of the Monarch machine and further description thereof is deemed unnecessary.

In accordance with my present invention the card guide 'is formed at thcupper portion thereof with two arms 48 situated on opposite sides of the printing point inclicated by the letter a in Fig. 2 and defined by the space between the portions 49 on the fingers and which is in alinement with the pointer 45. The arms 48 are notched or recessed to provide an openin through which the types strike and the bottom wall of which forms indicating edges 50 on opposite sides of the printing point and which constitute a printing line indicator that registers with the printing line indicated by the dotted line a in Fig. 2. In this figure it will be seen that the line indicating edges '50 register with the bottom edges of the letters or characters at the printing line and arefleach pro= vided with a scale or letter space indices 51 that correspond with the scale 47 and indicate the letter space distance between the characters. The arms 48 extend across the printing line forming extensions 52 having inner parallel side walls or edges 53 and each provided with a line spacing scale 54 that extends at right angles to the printing line in dicator and transversely of the platen. The

indices forming the scale 5e are preferably arranged close together and the indices on one scale register with those on the other. The object of these two scales 54 is to provide indicating means by which the distance from a previously written line, indicated by the dotted line b, to the rinting line a may be measured, thus a ording indicating means by which to effect a uniform spacing between lines when no other means for this purpose is provided, as when the fractional line spacing mechanism is in use. It will be understood that the particular scale marks on the scale 54 when used will depend upon the distance that it is desired to provide be-- tween lines.

In the operation of the devices or indicating means it may be assumed that the fractional line spacing mechanism is in operation and that it is desired to write on index cards provided with lines which differ from line spacing that may be effected with the ordinary line spacing mechanism of the machine or that blank cards are employed and it is desired to write the lines on said cards closer together than is provided for by the ordinary line spacing mechanism. The operator may introduce a card or Worksheet 0 into the machine in the usual manner and the platen is turned until the proper portion of the work sheet where it is desired to begin the first line of writing is brought to the line indicators 50 and the first line indicated at b may be written. Theoperator may then turn the platen until the printed line is indices on the scales 54, the distance between which and the printingv line indicators determines the space between the lines. The operator keeps in mind which is the index mark on the scales 54: to be employed. The second line may then be written and after this line is completed the card or work sheet may be set for the third line of writing by merely turning the platen until the second written line is in register with the same marks on the scales 54 that were employed ,in the first instance. The operatormay then proceed to write the third line and so on in definitelyand all lines will be spaced-a uniform distance apart, the indicating mechanisih assuring wlth mechanical accuracy the proper spacing between lines, affording a neat appearance in the work produced and the operator does .not have to rely merely Jeeaeai upon judgment in order to secure the proper and uniform spacing between lines as heretofore.

In some classes of card index work a line is written on a scale and the card is removed from the machine until some future time when it is again introduced into the machine and a second line is written just below and'close to the first line, the distance between the lines usually being less than that provided for by the ordinary line spacing mechanism. The card is then removed and at some future time it is again inserted inthe-machine and the third line written and so on until the card is filled. By my present invention this class of work not only can be more rapidly effected than heretofore but the spacing between the various lines on each card and the spacing on the various cards will be uniform, thus greatly enhancing the neatness in their appearance. It will also be understood that the indicating means of my inventionare also especially convenient in making corrections and altera tions and from certain aspects of my invention the indicating devices may be considered apart from the paper guiding and feeding devices or card guide of which they form part and regarded solely as indicating means, whereas from cert-am other aspects the indicating devices may be regarded aspart of the card guide or paper feeding devices. The latter are particularly efiicientin the present construction, inasmuch as the arms 48 of the card guide, or the extensions 52 thereof, extend across .the printing line and form an efiicient card guide which presses the card or paper against the platen at the printing line and adjacent to the printing pointand prevent it from bulging this point no matter how stiff the cards employed may be, thus preventing blurring imprints from being produced and deliver ing or guiding the work sheet or card 0 to the usual paper guides or fingers 55 and leaving no space whatever longitudinally of the platen between the card guide and the paper fingers 55, so that the card is mainriage.

.that arecarried by a tamed under pressure bythe card uide at and above and below the printing inc and adjacent the printing point at all times.
