LINE-MAKING ATTACHMENT FOR 'rxrnwnrrme-uacnmns.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed March 27, 1920. Serial No. 869,207.

To all whom it may concern:

Be it known that I, RICARDO GUERRERO PEREIRA, a citizen of the Republic of Chile, and a resident of Valparaiso, Chile, South America,have invented a new and Improved Line-Making Attachment for Typewriting- Machines, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved line-making attachment for typewriting machines, arranged to permit the user to quickly and accurately produce horizontal or vertical lines or combinations of the same, and such as. are used in making out statements, diagrams, invoices and other typewritten matter.

Another object is to permit of readily applying the attachment to various types of typewriting machines without requiring any or, at the utmost, but slight changes in the general construction of the typewriting machines.

Another object is to permit of drawing successively a plurality of vertical lines spaced desired distances apart and without requiring shifting of the carriage.

With these and other objects in view, the invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a art of this specification, in which similar characters. of reference indicate correspondin parts in all the views.

Figure 1 is a p an'view of the improved line-making attachment as applied to an Underwood typewriting machine;

Fig. 2 is an enlarged plan view of the line-making attachment;

Fig. 3 is a cross section of the same on the line 3-3 of Fig. 2;

Fig. 4 is a sectional front elevation of the same on the line 44 of Fig. 2; and

Fig. 5 is a sectional plan view of the attaching clip in position on the top bar guide of the typewritmg machine.

he improved line-making attachment for a typewriting machine is arranged in front of the cylinder or roller platen 10, on which.

is held the paper 11 adapted to receive the desired typewritten matter, and horizontal .and vertical lines 12 and 13 adapted to be produced by a line-makin attachment, as hereinafter more fully exp ained. It is understood that the platen 10' is mounted to turn in the usual manner in the carriage 14.- adapted to travel sidewise from right to left, and from left to right, as is well known. As shown in Figs. 1, 3, 4 and 5, the linemaking attachment is mounted on a station ary type bar guide 15 of the typewriting machine, and for this purpose use is made of an approximately inverted U-shaped spring clip 20 having clamping jaws 21 clampingly engaging the outer sides of the type bar guide. The spring clip 20 is sufficiently high to permit the passage of the type end of the type bar making an impression at the time on the paper 11, and the top of the clip 20 is attached to the under side of a guideway 25 ranging sidewise approximately parallel to the cylinder or roller platen 10. In the guideway 25 is mounted to slide sidewise a slide 26 having an upturned threaded lug 27 in which screws an adjusting screw 28 mounted to turn in the upturned lug 29 forming an integral part of one end of the guideway 25. The screw 28 is provided with a suitable knurled head 30 to permit the user to conveniently turn the screw 28 with a view to shift the slide 26 sidewise, either from the right .to the left or from the left to the right according to the direction in which the screw 28 is turned at the time. The slide 26 is provided with a post 35 on which is secured a tube 36 slightl inclined downwardly and rearwardly, wit

its axis approximately intersecting the axis of the cylinder or roller platen 10. In the tube 36 is mounted to slide transversely a holder 4:0 for carrying a pen, pencil or other writing implement 41 adapted to draw the horizontal lines 12 or the vertical lines 13 on the operator pushing the holder 40 rearwardly in the tube 36 to engage the writin implement with the paper 11. Now it wi be noticed that when the writing implement 41 is in contact with the paper 11, and the carriage 14 of the typewriter is shifted from the left to the right or from the ri ht to the left, then a horizontal line 12 is rawn on the paper 11, and when the writing 1mplement 41 is in contact with the paper 11 and a turning movement is given to the roller or cylinder platen 10 then a vertical line 13 is drawn on the paper 11.

The writing'implement holder 40 is preferably in the form of a shell 42 mounted to slide in the tube 36 and pressed on by a spring 43 resting at one end against the upper end of the tube 36 and abutting with its other end on a head 44 attached to the outer end. of the shell 42. A stop pin 45 is attached to the shell 42 and extends through a slot 46 formed in the top of the tube 36. to limit the movement of the shell 42 in the tube 36. It is understood that the spring 43 normally holds the writing implement 41 in retracted position, that is, a short distance away from the peripheral face of the roller or cylinder platen 10. The shell 42 is provided at its forward end with jaws 50 clampingly engaging the writing implement 41, and the jaws 50 are held 1n clamping position by the usual jaw-closing and opening member 51 screwing on the threaded portion 52 of the shell 42. The writing implement 41 may be in the form of a lead pencil or an ink point.

It is understood that when the operator desires to make a horizontal line 12 on the paper 11 then the operator pushes on the head 44 to move the writing implement 41 in contact with the paper 11, and then the operator shifts the carriage 14 either to the right or to the left to draw a horizontal line on the paper 11 at the desired place. When this has been done, the operator releases the pressure on the head 44 to allow the spring 43 to retract the holder 40. When it is desired to draw a vertical line, the operator pushes the head 44 to engage the writing implement 41 with the paper 11 at the desired point to which the carriage 14 was shifted, and then the operator turns the roller or cylinder platen 10 to correspondingly move the paper 11 whereby a vertical line is drawn on the paper by the writing implement 41. lVhen it is desired to draw another vertical line alongside but spaced from the first made vertical line and without shifting the carriage 14, it is only necessary for the operator to turn the screw 28 to shift the slide 26 and with it the tube 36 and the holder 40 to the right or to the left the desired distance to be had between the line made and the next line to be made. The operator then pushes the tube holder the same as previously explained and then turns the platen 10 whereby a second vertical line is drawn on the paper 11 either to the right or to the left of the first line according to the direction in which the slide 26 is shifted.

From the foregoing it will be seen that the line-making attachment for the typewriting machine is very simple and durable in construction and can be readily applied to a typewriting machine without requiring changes in the construction thereof.

Instead of mounting the line-making attachment on the stationary type bar guide 15, it may be attached to a lever actuated by a special key which when pressed moves the device into the desired position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A line-making attachment for typewriting machines comprising a supporting member having a portion adapted to be attached to the stationary type bar guide of a typewriting machine, and a channel shaped portion extending transversely of the machine, a slide mounted on the supporting member through the medium of said channel shaped portion and conforming thereto, means for adjusting the slide longitudinally of the transverse portion parallel to the platen of the machine :and securing it in adjusted position, a writing implement holder carried by and movable with the guide, a stylus-like implement carried by the holder and extending in juxtaposition to the platen and a spring yieldably pressing the writing implement outwardly to normally maintain the same out of contact with the work and adapted to permit movement thereof manually into engagement with the work, substantially in the manner as and for the purposes specified.
