The object of the present invention is to provide a simple attachment for typewriters whereby the underscoring of words or phrases or the formation oi leader lines will be tacilitated. The invention also has for its object the provision of means whereby lines may be made easily and rapidly transversely of the platen of the typewriter to extend vertically upon the sheet of written matter is or the lines may be drawn obliquely upon the sheet so that any desired formation may be produced to entirely enclose matter which is to be emphasized or to form captions or toconnect any desired words or phrases. The invention also seeks to provide a mechanism for the stated purpose which will be compact, will not interfere with the usual operation of the typewriter in any way and which will be set in working position by pressure upon so a key disposed at or adjacent the keyboard of the machine. The several stated objects, and other objects which will appear incidentally in the course of the following description, are attained in such a mechanism as is illustrated in the accompanying drawings, and the invention resides in certain novel features which .will be particularly pointed out in the claims.

In the accompanying drawings:

Figure 1 is a plan view of one embodiment of the invention showing the same applied to a typewriter, with those parts of the typewriter not necessary to an understanding of the invention being omitted for the sake of 85 clearness,

Fig. 2 is a side elevation of the same,

Fig. 3 is an enlarged detail perspective of the attachment removed from the typewriter,

Fig. 4 is an enlarged section on the line I 4- 1 of Fig. 3, and

Fig. 5 is a section taken longitudinally through the marker.

The typewriter, indicated 'as an entirety at 1, may be of any well known or approved form and is equipped with thevusual platen 2 over which the sheet for receiving'the typewriting is disposed and past which it is fed in the operation of the typewriter. In car-' rying out the present invention, there is' pro- 1930. Serial No.'465,431.

vided a marker 3 which may be a pencil or a stylus and which is provided with a marking point e adapted to impress upon the typewritten sheet a horizontal, a vertical or an oblique line when properly manipulated. The marking point 4: in the present instance is shown as fitted in the end of a holder 5 and extending axially therefrom through a retaining cap 6, the holderfi being slidably fitted within a tubular casing '4' housed within which is an expansion spring 8 bearing upon the holder so as to project the same from the casing. At its forward end the casing is constructed with a ball 9 fitting within a spherical socket 10 and held therein in a set position by a thumb screw 11 mounted in the wall of the socket and hearing against the ball, as clearly shown in Fig. 5. A locking projection 12- is formed on the upper side of socket 310 and a rack 13 is engaged with said projection to hold'the marker in a set position against the force of the spring 8, as will be understood upon reference to Fig. 5, the rack being formed on the lower edge of a bar 14 which is secured at its front end to the holder 5 and projects rearwardly therefrom through a guide loop or keeper 15 formed on the socket 9. The holding bar 14 is equipped with an enlargement 16 at its front end which constitutes a handle and in the keeper or guide loop 15 is secured a leaf spring 17 which bears upon the bar so that the rack 13 will be held in engagement with the projection 12 to lock the marker in its adjusted position. The socket 1.0 is formed at the upper end of an arm 18 which has a hub or sleeve 19 formed at its lower end and said sleeve or hub is fitted around and secured to a rock shaft 20 which is mounted at the front of the typewriter in any convenient manner. The drawings show the rock shaft mounted within a bore formed in a bar 21 which is a fixed part of an ordinary typewriter frameand has margin stops 22 mounted thereon. This arrangement is convenient and avoids the addition of extra parts to the machine but, of course, the rock shaft may be otherwise mounted, provided its allotted functions may be served. The bar 21 is provided at its center with a slot 100 or opening 23 to accommodate the sleeve or hub 19, and the arm 18 and the hub are secured in a set position by a set screw or bolt 24 mounted in the hub and bearing against 5 the rock shaft, as will be understood. At the right hand end of the rock shaft 20, I secure thereto a crank arm 25 which is disposed exteriorly of the typewriter frame and normalprojects downwardly and rearwardly 1 fi om the rock shaft, the rear end of the crank arm being curved eccentrically, as shown at 26, and provided with an upwardly projecting finger or extension 27 to provide a track for a roller 28 at the end of a presser bar or arm 29. The crank arm 25 is normally held in a raised position by a retractile spring 30 attached thereto and to the typewriter frame at a point above the arm, as best shown in Fig. 2, and this spring obviously serves to maintain engagement between the track of the crank arm and the roller 28. The presser arm or bar 29 is secured upon a vertically disposed rod 31 which is slidably mounted in suitable bearings and guides 32 on the side of the typewriter frame and is equipped near its lower end with a lateral stud or pin 32', said stud being engaged in the forked end 33 of a rocking arm 34 which is fulcrumed between its ends upon the side of the typewriter frame and is yieldably held in its normal position by a retractile spring 35 which is attached to the rocking arm at the rear of its fulcrum and also attached to some fixed point of the typewriter frame above the rocking arm, as shown at 36. The front end of the rocking arm 34 is provided with a depending lug or tooth 37 which is op-, posed to and adapted to ride on a similar lug or tooth 38 upstanding at the rear end of an angle lever 39 which is fulcrumed at its angle upon the side of the typewriter frame adjacent the front of the keyboard, the front arm of this lever extending upwardly and terminating in a key or push button 40, as shown.

The mechanism thus far described is sufficient to effect marking of lines upon the typewritten sheet, but in order that the work may be facilitated, I provide means whereby the typewriter carriage may be released to be moved backward so as to facilitate the work. To this end, the vertically disposed reciproeating rod 31 is extended above the presser arm 29 and is then bent laterally, as shown at 41 in Fig. 3, to pass outwardly beyond the typewriter frame a sufiicient distance to accommodate the extreme movement of the carriage, the carriage being indicated at 42 in Fig. 1. From the lateral extension 41, a short vertical connecting portion 43 rises and from the upper end of this short vertical portion a rod 44 extends inwardly over the carriage and may be provided at its inner extremity with an abutment or stop 45 of any convenient form. The upper member 44 passes over the escapement release lever, indicated at 46, to bear. thereon so that when a downward impulse is imparted to the rod 31 the escapement lever will be released and the carriage may then be moved freely in either direction. The stop 45 is preferably in the form of a lateral lip or lug at one end of a stem or shank 47 fitting within a socket formed in the end of the rod member 44 and held therein by a set screw 48, as shown in Fig. 3, this arrangement permitting the stop to be adjusted so as to conform to any given circumstances. To reduce frictional wear, a roller 49 may be mounted upon the escapement lever 46 under the rod 44 so that there will be no interference with the free movement of the typewriter carriage.

The marker 4 obviously is normally out of contact with the sheet of typewriting and a very slight movement will sufiice to bring it into contact with said sheet. In order that the sheet may be held smooth and firm when the marker 4 is in contact therewith, presser members 50 are provided upon the holder 5 and extend from the opposite sides of the same, these presser members being resilient arms equipped with rollers 51 at their free ends to bear against the sheet of paper in an obvious manner.

It is thought the manner of using the device will be readily understood from the foregoing description, taken in connection with the accompanying drawings. The typewriter is operated in the usual manner to transcribe the work. When it is desired to underscore or overscore portions of the typewritten matter or to connect portions of the same, the key 40 is pressed downwardly thereby rocking the angle lever 39 and, through the engagement of the lugs or teeth 38 and 37, oscillating the rocking arm 34 so that its rear end will be moved downwardly, as shown by the full lines in Fig. 2. The downward movement of the rear end of the arm 34 will obviously be imparted directly to the vertical rod 31 and the presser arm 29 will, consequently, ride downwardly with respect to the crank arm 25 so that said arm will be swung downwardly and the shaft 20 rocked to shift the marker from the position shown by dotted lines in Fig. 2 to that shown by full lines so that the marker point 4 will bear upon the paper. At the same time that the marker is thus moved rearwardly against the typewritten sheet, the upper extension 44 ,is caused to press downwardly upon the typewriter escapement release lever 46 so that the carriage will be released and if it is not restrained it will move quickly towards its initial position and, consequently,

a line will be drawn horizontally across the sheet. Upon reference to Fig. 1, it will be noted that the marker is located at the center of the escapement scale upon the typewriter, and it will be understood that the movement of the carriagemay be controlled manually by the operator so that the marker will be set to begin the line at a desired point and also controlled to terminate the line at the desired point. The marker will remain in contact with the typewritten sheet as long as the key 40 is depressed and when said key is released the parts will be returned to the initial positions indicated by the dotted lines in Fig. 2 under the influence of the springs 30 and 35, as will be understood. While the carriage is moving across the machine, the platen may be rotated and as a result of this action an oblique line will be drawn upon the paper. If it be desiredto make avertical line, the car riage is shifted to the desired point, whereupon the key 40 is depressed and the platen then rotated through the are necessary to inscribe a vertical line of the desired extent.

It will thus be seen that lines of any desired arrangement may be made upon the type- I written sheet with facility and speed and without requiring the operator to do any unnecessary or laborious work. The arrangement is very simple and compact and is not apt to get out of order.

Having thus described the invention, I.
