PROCESS O1 MANHOLDING Application fled September 28, 1927. Serial No. 229,866.

My invention relates to the forming of manifolding copies in a'series of superimposed forms or pieces of paper which shall be perforated as well as imprinted with a coloredl impression, so as to be entirely safe against alterations.

It is my object to employ in the marking of manifold copies a type face or reciprocating perforating pin which penetrates all of the sheets upon which the manifold impression is to be made, and to pigment or color cause of its tendency to smudge, wear out,

make indistinct copies and limit the number of copies that canbe manifolded. In'stead of thls, and instead of using manifoldin cloth or-printing cloth, I employ a kind 0 hard coating,

coated paper which has a particular quality that suits my process. This paper is coated on the side which will lienext above a iece of paper to be marked with anon-smu ging and contains those elements which gree, and shouldhave a color which contrasts markedly with the color of the piece of paper that is to be marked. In the paper trade, a stock grade of this type of paper isknown as-glazed coated paper, and is readily obtainable, and demonstrates the process.

I have found that if such a permanently coated paper or other types of color coated paper where the color coat is not smudgy or easily dislodged, is employed, that I can by using a perforatmgfipin or a type face formed of pins, readily slodge suflicient of the color coating from an upper. coated web to igmjent the walls of the oles made in the ower web by the perforating element.- While not as brightly pigmented as were carbonized paper used, or a printing ribbon or the like, the color is not smud at all,

and while it can be erased, it remain which are coate give a permanent like finish to the paper. The coating is. preferably of such a type that it will be brittle to a certain dequite permanently about the perforations so as to color them and render the reading of them easy.

The best mode of practicing my invention is to use a paper coated on the underside with color and left white or with a pale color on the top side, with the top side imprinted with whatever form is being used. It is not practical in ordinary industrial uses to employ manifold slips and forms which are coated with carbon paper finish on the underside because of the smudging of anything with which such a form comes in contact. With the use of the special coating or anyother relatively permanent color coating, I am, enabled to do away with the interleaving of any copypaper whatever between the forms in a manifolding machine, and it also enables me to make many more copies at one writing.

'The most expensive element in the use of manifolding machines to-day is not the rinted paper issued thereby, but the caron paper which is used. Also, when a-large num er of forms must be made as copies, there'will have to be twice as thick a bundle for the type to act upon as would be required, were it ractical to use form sheets if on the back with removable carbon.

Thus my invention eliminates the cost of carbon sheets, makes it practical to form a larger number of copies at one writing than in the past, and it makes good legible copies throughout.

I accom lish my objects'b that certain process to pointed out in etail, and for the use of which a typical mechanism will be shown and described.

y process can be employed with a typewriter having type faces formed of pointed pins spaced from each other andarranged in the shape of a desired character or letter. It can also be employed with a-stylus having a reciprocating point that is operated somewhat after the fashion of a flexible shaft dentists tool. a

I have shown, however, only the typewriter mechanism which will sufiice to explain the nature of my invention.

I have illustrated a typewriter 1 mounted to move to and fro and forward and back on'a frame 2. A storage roll for manifold paper webs, such as printed form, is shown at 3. This paper will preferably be coated han on the back with a color coat. I have illustrated one of the webs at 3, as having a color coating 3?. As stated, this color coating should be of'non-smudging type, and preferably should be a coating of a color which strikingly contrasts with the printed form face of the paper, or if not printed, the color of the face of the paper upon which writing or tvping is to be done.

T e typewriter will have its type arms as at 4 equipped at the ends with pins 5 driven into the ends, which pins carry type bodies 6. The type bodies 6 have each a set of pins 7 which are sharp pointed and arranged in the shape of the desired character or letter. They will normally be held in the type body by means of Babbitt metal.

Mounted on the typewriter and moving therewith I provide an abutment plate 8 against which the type bodies will strike,

said abutment plates being arran ed to overfolding machine. The pins of the type are provided clearance by a notch 8 in the plate. The paper is laid across the platen of the machine and held down as by the usual clamp bar 9 of the Elliott Fisher machines, and the usual ribbons 9 employed for the top web.

As the ty manner, stri ing the selected type arms down against the paper, the pins will penetrate a of the forms. Since the forms have on the usual ribbon guide 0 the mani ewriter is operated in the usual'" 1.
