1 Claim.

My invention is an improvement in the art of producing impressions of characters, lines and representations of any kind upon surfaces adapted to retain such impressions; and apparatus therefor; which can be utilized without recourse to lead pencils or ink or the other ordinary adjuncts employed for writing and printing.

It is an important object of this invention to provide means for facilitating typewriting without the conventional ribbon, for printing without ink, and for the tracing of lines and other marks upon specially prepared paper without the usual pencils which require to be continually resharp ened to maintain them in readiness for use. The paper employed has a smooth finished surface containing gritty particles, such as sand; I and the types or other marking elements are made of some suitable soft metal which will be scraped by the particles of gritty material whenever they come into contact with the particles; thus leaving small bits and pieces on the paper with the same outline as the character desired.

The nature and advantages of the improvement are fully described in the ensuing description and the novel features are defined in the appended claim. The drawings illustrate several forms of my invention; but I can of course vary the details without departing from the principle of the improvement herein set forth.

On said drawings:

Figure 1 is a perspective view of the end of the type bar of a typewriting machine bearing a letter, for example, on the end; this letter containing metal adapted to give th effect desired.

Figure 2 is a section along line 22 on Figure 1.

Figure 3 is a view similar to Figure 2, but showing a modification.

Figure 4 is a perspective view of a sheet of paper or the like which receives impressions from the types on the bar of Figure l, or in a printing press.

Figure 5 is a view partly in section of an instrument for drawing lines or writing on such a sheet.

Figure 6 shows in perspective a clip for holding tracing parts or elements of suitable soft metal in the end of such an instrument.

Figure 7 shows in side elevation a number of such parts.

Fig. 8 shows an accessory for such an instrument.

Figures 9 and 10 are side elevations of another part or tracing element of suitable metal for the end of such an instrument.

Figure 11 shows a sample of lines ruled with such an instrument upon specially prepared paper.

Figure 12 shows in perspective a drawing board and instrument for ruling parallel lines upon such paper.

Figure 13 is an enlarged plan view of the prin-- cipal parts of such an instrument.

Figure 14 is a section taken along the line [4-44 on Figure 13.

Figure 15 is a section taken along the line [5-45 in Figure 13.

Figure 16 is a view showing a modification of the instrument of Figure 13; and:

Figure 1'7 is a cross section on line Il-l1 of Figure 16.

The numeral l indicates the end of the type bar 2 of a typewriting machine; and on this end is the outline 3 of a letter or any other desired character. For example, the outline 3 has the form of the letter a, small, and A, large. The end I is of ordinary material, but the outline is of some relatively soft metal, such as aluminum, copper, silver or other material having no great hardness. The pieces of paper shown in Figure 4 on an exaggerated scale has a fiber body i and the surface thereof has a coating of clay 5, or other substance giving a smooth finish on the surface, in which the gritty particles 6 are em bedded and distributed throughout. Whenever the face of the outline 3 strikes or is pressed against the clay finish coating 5, the particles 5 will pull off small bits of metal in the outline 3, and a perfect reproduction of the character represented by the outline 3 is obtained on the paper. By typewriting in this way, the usual ribbon can be discarded; and if types are used in a printing press, no ink is necessary.

Figure 3 shows a piece of such soft metal l0 retained in a seat or cavity in the extremity of the bar 2. The quantity of metal abraded by the particles 5 from the face of the outline 3 is so minute that the outline will last a long time before wearing out.

In Figure 5 a tracing instrument is shown in two sections II and I2, screwed together. The body of the instrument has a cavity or magazine inside for pointed tracing elements of soft metal. The section l2 has a bore extending into its outer end to receive a clip [6 which grips and holds a tracing element 45. The clip is in two parts that are secured to each other by a binding screw H. The clip fits the bore or recess l4 snugly, and the instrument can be utilized to write or draw lines on the paper of Figure 4. The opposite end on the instrument can carry another tracing element l8, secured in place in any feasible way.

Figure 6 shows a similar clip capable of holding a number of pointed metal tracing elements so longitudinal slot 43.

as to draw parallel lines. The clip is made of two parts l9 with widened outer ends, and opposed recesses 20 on the inner faces. The parts [9 are secured to each other as before by a binding screw I! with elements l between them, and this clip is inserted into the bore [4 in the same manner.

Figure 7 presents a number of such tracing elements 24-28 inclusive, with ends sharpened to draw single lines, light or thin or heavy broad lines and parallel lines. Figures 9 and 10 show such an element 29 with two points 33 close together and an isolated point 3| on the end, so as to produce lines 32 and 33 in Figure 11 on an accountants sheet, to mark the totals.

Figure 8 illustrates an instrument having a stem 2|, with a wide end having several bores or recesses 22 side by side to receive tracing elements l5, held in by screws 17. A piece 23, with one end bent over the outer extremities of the elements 15, and the other bent and fitting into a notch in the stem 2|, alines the outer ends of the elements l5.

With instruments carrying pointed tracing elements of soft metal l5, lines can be drawn upon the surface of the paper shown in Figure 4. The elements never have to be resharpened, and they last for a long time.

Figures 12, 13 and 14 present a drawing board 34, having a sheet of paper 4 thereon, with a surface as described above in connection with Figure 4. A T-square 35 having a longitudinal ridge 36 is laid on the paper 4. This T-square has a slider 37 with a channel on its lower face fitting upon the rib 36, and can be moved along the T-square. To the slider member 37 an arm 38 carrying several tracer elements 39 is pivotally connected by means of a screw and stud 40. The arm'30 can therefore be left free to revolve or be fixed in any desired position. It can be held at any point on the bar 36 by means of a screw 4|. The elements 24 are all mounted in hollow bosses 42, having screw-threaded engagement with the arm 38. The tracer elements are of course of soft metal and will draw parallel lines curved or straight on the paper 1.

Figures 16 and 17 illustrate the arm 33 with a In this slot and engaging one side is a channel strip 44. Afiixed to this strip are several bosses 42 carrying the tracer elements. The bosses extend into the slot, and hold the channel strip against one edge of the slot. A binding screw 45 in the arm 38 retains the strip with the tracer elements in position. The strip and the elements 24 can be held in any selected position in the slot 43.

Having described my invention, what I believe to be new is:

A writing instrument having two sections detachably joined end to end to form a body having a closed cavity within it, one of said sections having a recess at its outer end, a clip made of two divided parts, one end of said clip being tightly engaged in said recess, a binding screw carried by the clip to hold said parts together, the clip being bent between its ends, and one or more tracing elements clamped between the outer ends of said parts.
